SCHOOLS OF MINES. The beneficial results attendant on the establishment of these schools continue to be felt in the mining centres. Opportunity is afforded enabling advanced students as well as working miners to acquire knowledge of the various subjects necessary to those desiring to follow up the profession of mining engineers and managers, and also of other subjects required in carrying out all successful mining enterprises. The long-felt need of a higher technical education, combined with practical knowledge of everyday work, in connection with the development of the mineral wealth of the colony has in a marked degree been met, and the interest evinced in the classes is shown by the increased number of students attending the principal schools, and by the desire expressed by the miners for the establishment of schools in districts at a distance from the present centres. The large number of students coming forward clearly shows it to be a recognised fact that, unless those engaged in mining pursuits wish to be left behind, they must avail themselves of the opportunity for acquiring the scientific knowledge now so necessary to all who desire to become leaders in the conduct of mining enterprises. Well-equipped schools at the chief places, in which a continuous course of instruction is carried on, are infinitely preferable to smaller schools, where the time devoted to teaching is intermittent, and less opportunity afforded for obtaining a thorough knowledge of the subjects forming the groundwork of the necessary studies. THAMES SCHOOL. The attendance at this school continued to increase during the year, the average being 103» as against 56-5 for the preceding year. The number of assays made —viz., 1,796, as against 1,103 for the preceding year—shows a large increase, whilst seventy-four parcels of ore were treated at the experimental plant, as against forty-five for last year. There are many advantages consequent on having the school in a central position like the Thames, where all branches of gold-mining are carried on. The scientific treatment of ores by different processes can be readily witnessed, and the Director is in a position to at all times explain matters which otherwise, in the absence of practical illustration, would be more difficult. The experimental plant in connection with the school is shortly to receive an addition which will place it in a position to be more readily used in treating parcels of ore. The two stamps are to be removed, and a battery of three stamps, suitable either for wet or dry crushing, with a rockbreaker and all the most modern appliances for the scientific treatment of different kinds of ore, is to be erected. The advantages named in a great measure tend to insure this school maintaining the foremost position in point of attendance and practical results. Mr. F. B. Allen, M.A., B.Sc, was appointed Director of the school as successor to Mr. James Park, F.G.S., who resigned his appointment during the year. Mr. Allen's position as assistant to Mr. Park enabled him to enter on the duties and follow up the system hitherto adopted in the successful conduct of the school. The following is the report furnished by Mr. Allen on the progress made at the Thames School for the past year:— I have the honour to report that the year 1896-97 has been an extremely busy and a successful one for the school, which has made exceptional strides, and is now in a flourishing condition. Consequent on the revival in mining on the peninsula the school has been busily and constantly employed assaying and treating parcels of ore for the public, and has afforded a ready means of ascertaining the value of the numerous new finds which have been made during the past year. Besides this, large numbers of new students, both young men just entering the field of mining and also working miners, have taken advantage of the courses of study at the school, and have been qualifying themselves for the various public examinations, as well as for work in the mines and batteries. The mining students are becoming thoroughly alive to the fact that scientific training will materially assist them in their daily avocations, and enable them, when in charge of works, to develop their mines and carry on the operations connected with the winning of gold to better advantage. That the amount of public work performed by the school during the past year, as well as the attendance, have practically increased twofold shows that the school has kept pace with the mining revival, and is thoroughly appreciated. An inspection of the tables accompanying this report will show that the public work and the attendance at the classes rapidly increased from May, 1896, onwards; and, as Mr. James Park, F.G.S., who had so ably directed the school for some seven years, and brought it into an efficient condition, severed his connection with the institution at the end of April, 1896, I was left single-handed to carry on the whole work of the school, just at the time when public assays and battery-work were rapidly increasing, and when new students were entering every week. This entailed very long hours on my part to keep everything in working-order, but after four months an assistant, Mr. P. G. Morgan, M.A., was appointed as Assistant Lecturer and Assayer. This was in September, and since that time he has ably discharged his duties, and has relieved me in great measure from the excessive amount of work entailed by increase in every department of the school. The average attendance of registered students has increased from 565 in 1895-96 to 103 for the year 1896-97, and, as the attendance has continued to progressively increase from the beginning of 1896 up to the present time, it is now far in excess of that of any previous period in the history of the Institution. The assaying classes are, as usual, largely attended, but it is a pleasing and noteworthy fact that in the mining and surveying classes, which are in great part made up of practical miners who attend after their daily work in the mines is over, the increase has also been large. The surveying-class roll shows an increase from twenty-six in 1896 to fifty-three for the first term of 1897, and the mining class an increase from twenty-five to fifty, in each case double that of the preceding year. The school is now taxed to its utmost capacity in finding accommodation for these students.

There has been a corresponding advance in the amount of work performed for the public in the shape of assays and analyses and the treatment of ton parcels of ore by the plant, showing that the school retains the confidence of the mining community as an accurate and reliable institution for the valuation of ores. The following table gives a comparative view of the number of assays performed during the last two years : — 1895-96. 1896-97. Number of public assays ... ... ... ... 743 1,204 Number of assays in connection with ton parcels ... ... 360 592 Total ... ... ... ... ... 1,103 1,796 This increase to 1,796 in 1896-97 from the already large number of 1,103 in 1895-96 has been largely in consequence of the widespread prospecting which has been going on throughout the peninsula, and in the very nature of things it is reasonable to suppose there will be a falling-off again in the number of assays after a time. When the mining properties are more developed the companies will employ assayers of their own, and already a number of our students have left to take up positions of assayers at various up-country mines. The plant for the experimental treatment of ton parcels of ore has been, with the exception of one week's stoppage for repairs, continuously employed throughout the year, and during several weeks it was necessary to work double shifts in order to cope with the sometimes sudden influx of several separate tons of ore at one and the same time. During 1896-97 the plant treated seventyfour parcels of ore, of an aggregate weight of 122,9411b. dry weight, as against forty-five parcels, aggregating 80,4571b., in 1895-96. Of these seventy-four parcels, a table of which is given below, sixty-two were treated by pan-amalgamation and twelve by the cyanide process, and in the case of seven of the parcels it was necessary to chloridize roast the ore before amalgamation. The percentage saving on the average was, by cyanide, 64-75 per cent., and, by amalgamation, 82-9 per cent. It should be noted that most of the parcels were treated by cyanide at the request of the owners as experimental tests to ascertain to what extent the bullion could be successfully extracted by this process, but the results show that few of the parcels contained gold in a fine enough state of division for successful cyanide treatment direct. In most cases the bullion can be better extracted by amalgamation, followed by cyanide or other treatment of the tailings. The chief alterations to the plant during the last twelve months have been the erection of a larger percolation-vat in connection with the cyanide process, a second zinc-extractor, and a centrifugal pump for cyanide solutions. The vat is 7 ft. in diameter, is fitted with all necessary appliances, and has proved very suitable to our requirements. During the year it has been necessary to re-bed the mortar-block, and to make repairs to the amalgamating-pan and the furnace, while the Council now contemplate extensive alterations during the coming year. It is proposed to remove the present two stamps and erect a three-stamp battery instead, on a solid concrete foundation. This will necessitate the laying of a 9 in. main to drive the stamps, and the total cost, including the erection of a separate public assay-room, will amount to something like £800. Students are, subject to permission granted by the Director, allowed to work with the experimental plant, and many have taken advantage of this, and have derived considerable useful practical experience thereby in the metallurgical treatment of ores. In order to insure accuracy, as well as to keep the results from becoming public property, I have, during the last year, arranged that all public assays are performed by the Laboratory Assistant after the students have had their instruction in the classes ; so that when these assays are made no students are present and the public work goes on without interruption. This was a necessary alteration, and the very large number of assays performed for the public shows that reliance is placed in the methods adopted. Still, it has meant keeping the school working late and early, and the Laboratory Assistant has had an exceptionally busy year. My thanks are due to Mr. George Nicks, Mr. A. Jones, and Mr. F. Woolcock, who have in turn occupied this position creditably to themselves. They have each had their rewards, however, in that the large amount of practical experience gained by them as Laboratory Assistants has enabled each of them to secure a lucrative appointment with mining companies. The Mines Department has very kindly donated to the school a series of models imported from Germany, illustrative of the action of a plunger pump and man-engine and of the mode of contraction of various kinds of dams and sinking of shafts —all very useful models for practical demonstration of the lectures. The Government, through the courtesy of Sir James Hector and Mr. Alexander McKay, has made a gift of the past Geological Eeports, which will form a welcome and valuable addition to the library; while the thanks of the school are due to Mr. George Wilson, Inspecting Engineer of Mines, Mr. T. P. Moody, of Hikurangi, and others for various collections of rocks, coal, and minerals. I myself have made a collection of several hundred samples of auriferous quartz, which, as illustrating the different appearances assumed by the gangue of the precious metals mined on these fields, will, I trust, prove useful to the mining community. So many students enrolled themselves this present year in the drawing class that it was found necessary to obtain a special instructor for this important subject, and in March, 1897, Mr. John Parr, B.Sc, M.E., mechanical engineer, of Christchurch, was appointed drawing master, and is giving every satisfaction. The field geology class has been well attended throughout the year. Many trips, some of them necessitating hiring horses, have been made across country to illustrate the relation of the beds one to another, and excursions underground into the mines have also been made to give students the benefit of actual observation of the details of mining operations and the occurrence of mineral deposits. Excursions to one place or another are made weekly, and are invaluable as affording practical illustration of the subjects discussed in the lectures. My thanks are due to the members of the Council, who have given me their assistance throughout the year, and have shown that, all along, they are greatly interested in all that concerns the wel-

fare of the school. I have much pleasure in acknowledging the services of Mr. P. G. Morgan, M.A., the Assistant Lecturer, and also the valuable work done in the plant by Mr. Eichard Vercoe, who has proved himself most reliable and painstaking in the discharge of his duties. The following is a table of the attendances at th c several classes : —
Table of Attendances for Year ending 31st March, 1897.
The annual examinations were held in December, 1896, the papers being set, as formerly, by examiners in Wellington appointed by the Government, viz.: Mr. H. A. Gordon, F.G.S.; Mr. William Skey, Government Analyst; Mr. Alexander McKay, F.G.S. ; and Mr. C. H. Pierard. Keeping pace with the increase in the attendances at the school, the number of candidates who presented themselves was more than double that of the preceding year. The results of the examination are shown in the following table. The President's medal for the best aggregate was awarded to Mr. K. M. Barrance, who also won the gold medal for surveying, presented by Mr. Ehodes, of the Kauri Estates Company. Mr. Barrance and Mr. Fleming sat for the School of Mines scholarship examination, but no award was made.

Eemaeks on the Parcels treated. The tailings from Waihi, which gave a poor extraction on pan treatment, had already been treated in pans before they were received at the school, and the second treatment, made at the request of the owner, showed that little could be extracted from the tailings by pan-amalgamation. A test on about 2 tons of the tailings by the cyanide process showed that 90 per cent, of the value could be extracted by this method. The parcels of ore sent to the plant this last year have been on the whole unsuitable for cyanide treatment, owing to the condition of the gold particles. Several parcels were treated by cyanide at the request of the owners, but the results were generally not high. The majority of the new finds are thus shown to be unsuited to treatment by this process. Nevertheless, I consider that the cyanide process can be successfully combined with wet-crushing and amalgamation for the economical treatment of many of the ores of the peninsula, and mine-managers would do well to experiment in this direction with a view to obviating the dry-crushing methods.

During the year I have supervised two Government examinations for mining managers and battery superintendents. At the first one, in May, 1896, one Thames student sat for first-class mining manager's certificate and two for the battery superintendent's certificate, and all three were
C.—3
12
successful in passing their examinations. In January, 1897, another examination was held, at which eleven Thames students sat for the first-class mining manager's papers and five for those of battery superintendents, but the results have not yet been made known. A feature of the Thames School is the practical nature of the instruction. The mines being in close proximity to the school afford exceptional opportunities for observing and illustrating the modes of development of mines and the different kinds and modes of occurrence of oredeposits. An examination is made every week of one of the mines or of the surrounding country, and besides this practical work in mining and geology there is a class for field-work in surveying both above and under ground. Moreover, as the school plant is constantly treating varied and complex ores from all parts of the field, students have regular practical work in assaying and metallurgy, and are enabled in a short time to obtain as much general information concerning ore treatment as they could obtain in a much longer time by actual work in a battery where usually only one process is in operation and only one class of ore treated at a time. Distribution of Prizes and Certificates. The annual distribution of prizes and certificates was performed in the school-building on the 9th February, 1897, by the President, Mr. J. McGowan, M.H.E., a large number of students being present. Governing Body. At the annual general meeting the following officers and members of the Council were elected for the ensuing year: President, Mr. J. McGowan, M.H.E. ; Vice-President, Mr. T. A. Dunlop ; members, Messrs. G. S. Clark, J. H. Smith, E. F. Adams, W. Burch, L. Melhose, M. Paul, G, Denby, P. C. Hansen; Treasurer, Mr. J. Hague Smith; Secretary, Mr. A. Bruce. EEEFTON SCHOOL. The falling-off in the number attending the school, due to the depression that prevailed for some years past, has not continued during the present year, the number of individuals having increased from twenty-five to thirty-three, and the work in the school in the matter of assaying and analysis is also greater, 973 assays and analyses being performed, as against 229 for the previous year. The Boatman's class, which was commenced with eleven members, was not successful, as the attendance fell off to five members, and it was then diseontinned. The classes at Brunnerton and at Denniston were not visited by the Directer during the year. The following is Mr. Aitken's report on the progress made at the Eeefton School during the year : — I have the honour to report on the work and progress of the Eeefton School of Mines during the past year ending 31st March, 1897, which I am pleased to say has been very successful, and a great improvement on that of the previous year. The classes were attended more regularly by the students, and the number of individuals attending increased from twenty-five to thirty-three. The membership to each class and the average attendance also show an improvement on that of the previous year. lam quite sure that as the district goes ahead the numbers attending the classes will increase; and when the committee are able to furnish the school with better appliances and stock it will induce many more to attend. Up to the end of 1896 no less than twenty-four students from this school have successfully passed the Government examinations for first-class mine managers, sixteen under the Mining Act and eight under the Coal-mines Act; besides these, a great many have been successfully prepared for the engine-drivers' and other examinations. In the laboratory we have been exceptionally busy, and, with our limited stock of chemicals and appliances, have been almost unable to overtake the work. During the past year we have performed 973 assays and analyses, as against 229 for the previous year, showing the large increase of 744. In the performance of this work I have to thank two of the students—Mr. J. Sutherland, who has lately received a position under the New Zealand Consolidated Company, and Mr. T. 0. Bishop, now attending the Otago University and School of Mines —for their able and willing assistance. In the early part of the year the laboratory was also being used by the assayer for the Consolidated Goldfields of New Zealand, when over 220 fire-assays were made in addition to those made for the school. The classes and laboratory work in connection with the Eeefton School have given me so much work that I have had but little time to attend to the outside schools. Brunnerton and Denniston were therefore not visited during the year ; and the class at Boatman's had to be discontinued early, owing to the small average attendance. The following tabulated statement will show the attendance at the classes during the past year:— Sub J eot ' Members. A^dance.

In the surveying class very little practical work could be done, as the school is without the necessary instruments. The practical work in the assaying, metallurgy, and chemistry classes was carried on under difficulties, owing to the poor appliances and insufficient supply of chemicals. The instruction given at the classes has been very much the same as that given in previous years.

Practical Assaying and Metallurgy. —The students were instructed in the wet and dry methods of assaying, use and composition of fluxes, fuels, reagents, &c, smelting, valuing, and refining of gold and silver bullion, amalgamation, retorting, &c. ; also in the various methods of extracting gold and silver from their ores, such as battery-work, amalgamation, concentration, cyaniding, and chlorination. This class has been very popular, and the instruction given is of great importance to those who wish to qualify as assayers or battery superintendents. Up to the present there has not been a great demand for assayers here, although some of the students have obtained good positions. Practical and Theoretical Chemistry. —As in the previous year, these two subjects were taken together, and the classes were fairly well attended. The theoretical chemistry was mostly confined to the non-metallic elements, and the chemistry of gold* silver, and mercury. Instruction was given in the preparation of reagents and salts, testing for acids and metals, separation and detection of metals and mineral substances, besides assays and analyses by gravimetric and volumetric methods. Land- and Mine-surveying. — This work was nearly all theoretical, owing to the want of instruments. Some practical work was done in levelling, forming, and grading ; also in planwork and drawing working sections. Instruction was given in chaining, tabulation of traverses, calculation of areas, heights, and distances, plotting, levelling, and laying out roads and races. With a good theodolite, level, and staff the attendances to this class would be greatly increased, and proper instruction cannot be given without the instruments. Mining and Mathematics. —The instruction given includes mining geology, logarithms, plane trigonometry, strength of materials, timbering, pumping, and pit-work, hauling and winding, ventilation, explosives, water-power, &c. This class is mostly attended by miners and those wishing to qualify as mine-managers and engine-drivers. Considering that most of the students live a considerable distance from the school, the attendance has been very good, Many are unable to attend regularly, owing to the different shifts, and therefore they miss some of the work done at the class, This is partly the reason they do not attempt the examination-papers. Boatman's School. —This school started with eleven members, but after doing a little work the average attendance went down to about five, so that the class had to be discontinued. Beefton School. —There has been but little done in the way of adding improvements to the school. A new muffle furnace has been erected, and the inside fittings of the laboratory have been altered for the convenience of the classes. The crushing of all the samples is done with pestle and mortar, and the assay sample is finely ground on a bucking-plate and muller. This method is very slow and tedious, and a good crushing and sampling machine is much needed. The stock of chemicals and apparatus is very poor, and we have been unable to test a lot of the work sent. We have only the one balance, which has to be used for both assay and chemical work, so that another is urgently needed, as in many cases very poor material has to be tested, and accurate assays and analyses must be made. The support given to the school has been much better than that of the previous year ; but, as the committee had to pay off the back debts, there was little left at their disposal for improvements to the school. The Laboratory. —ln this department a large amount of work has been done, no less than 973 assays and analyses being made, besides experiments, determinations of minerals, &c. This shows an increase of 744 on that of the previous year, whichis evidence of the amount of prospecting being done in the district. These tests are made up as follows : Fire-assays, 882; amalgamation tests, 67 (weight of stone, 4601b.); bullion assays and smeltings, 8; analyses, 2; cyanide tests, 2; tin assays, 3 ; platinum, ] ; scheelite, 2; galena, 3; chrome, 2 ; copper, 3. Most of the samples tested by amalgamation were quartz containing free gold. The greater number of the fire-assays were quartz samples. There were also a great many cements, gravels, and black sands tested. Many tests were made for the General Exploration Company on the cements and gravels extending along the coast at Charleston and Addison's. On all these samples, which are poor in gold, and where 1 dwt. per ton would pay to work, large assays from 1,000 gr. to 2,000 gr. had to be made in order to obtain correct returns. There has been a considerable amount of prospecting done throughout the district during the past year, and the want of a small testing plant has been frequently spoken about by prospectors and investors. I consider a small testing plant would be a great boon to this district, and would not only assist the prospector and mining companies, but would give our students practical work in the various processes for the extraction of gold and silver. The plant should be capable of treating up to 2 tons at least by wet- or dry-crushing, concentration, amalgamation, chlorination, or cyaniding. A small roasting-furnace would also be required. Experiments on a practical scale could then be made on quartz samples, cements, tailings, and concentrates, and I am quite sure would be productive of some good to the whole of the West Coast. Annual Examinations. —The annual examinations for students were held in December, 1896. The papers being set by a Government Board of Examiners, only a few of our students competed, and in the subjects taken show good work. The following are the results: —

Governing Body. —At the annual meeting the following committee were elected for the current year: President, Mr. W. Laving; Hon. Secretary, Mr. N. Lawn; Hon. Treasurer, Mr. T. H. Lee; members of committee, Messrs. G. Hufton, J. S. Matthews, Eev. T. Pinfold, and T. Watson. In conclusion, I must thank the committee for the valuable assistance they have given me in carrying on the work of the school, and I trust that the institution will continue to improve, and show some practical results at the end of the present year. OTAGO SCHOOL OP MINES. The attendance at this school has still further increased during the year 1896. The new plant for treatment of ore has been completed, and a number of parcels of quartz were crushed and treated by amalgamation or by the cyanide process. The following is the report of Professor George H. F. Ulrich, the Director of the school, on the progress .made during the past year, the personal notice of students and list of donations to the Mining Museum being omitted : — I have the honour to submit the following report regarding the attendance, work, and results of annual examinations of the School of Mines during the past session (1896), together with remarks on the practical teaching facilities, and on other points affecting the future progress of the school. The attendance number of students during the past session was thirty-eight, classed as thirtytwo regular students for the full course and six occasional ones for special subjects—principally assaying—only. Of the thirty-two regular students, nineteen were old ones returned for the completion or further prosecution of their studies (as detailed further on), whilst the other thirteen comprised new entries, including one student who had the previous session attended as an occasional one. Ten of the new students entered for the first year's course of the mining division, though several with the intention of going through four years' study, in order to enable them to gain in addition to the diploma of associate in mining that of associate in geology or the certificate of metallurgical chemist and assayer. Two students who had some years before gone through the first year's course of the mining division returned for the completion of their studies, and the thirteenth new student—being the holder of one of the three scholarships in mining established by the Hon. the Minister of Mines (Mr. Cadman), and tenable at the Otago University —entered for the study of the subjects of the geological division with the aim of gaining the B.Sc. degree in geology in the University of New Zealand. As the attendance number of students during the session of 1895 was twenty-seven, of whom only nineteen returned, the loss of eight is explained by three occasional students and of two who had the year before entered as regular students not returning, whilst the other three—viz., John Watt, Ernest Edwards, and John Orkney —had finished their studies and passed the prescribed examinations, as stated in my last year's report. After producing certificates of twelve months' engagement in practical work in mines they have since each been granted the diploma of associate in mining, and, in addition, John Watt and John Orkney the diploma of associate in metallurgy, and Ernest Edwards the certificate of metallurgical chemist and assayer, to which they were entitled. The attendance of the various classes by the thirty-two regular students was very satisfactory, only a small number having missed any lectures, and those mostly on account of illness. The ten new students passed through the first year's course with the exception of five—two who did not attend mathematics, one who failed in this subject, one who failed in mining geology, and one who failed in theoretical chemistry. Thirteen students passed through the second year's course of the mining division, save two who did not attend mineralogy —one who failed and one who did not sit for the examination in this subject. Three others did not take the classes in theoretical and practical physics, but as these, as well as the others who missed classes, have the intention of staying four years they can make up the deficiencies during next session. Eight students —some of four years' and one of three years' standing —finished their studies during the past session, and are leaving the school, having successfully passed the examinations in all the subjects prescribed for several of the divisions. With few exceptions, all these students took advantage of learning by the practical instruction and example of Mr. Fitzgerald, battery-work and gold-extraction by amalgamation and the cyanide process in working regularly four-hour shifts alternately from the time the testing of samples for the public was started. In compliance with applications, Mr. Fitzgerald arranged evening-classes in assaying, which were attended by six occasional students, five of whom came regularly all through the session, whilst the sixth stopped away after about three months' work. As the afternoon classes for the sixteen regular students in the first and second courses of assaying (which need at least three hours each for three afternoons per week, and necessarily require to be held together for want of other free time) were rather crowded, and the five available smelting furnaces proved quite inadequate for continuous steady working of these students, two of them, whose other lectures fortunately permitted it, attended the evening classes also, much to their own convenience and that of the other students of the afternoon classes. All the new students (eleven) who entered for the first year's course attended the evening class established by the St. John Ambulance Association, and were successful in passing the examination, and thereby gaining certificates of first aid as required by the regulations. On considering that the lecture-hours of the first year's course on any day of the week leave the hour free at which the ambulance class is generally held (which is not the case in the second and third year's courses), it was thought advisable to make attendance at that class part of the first year's course for the future, and prescribe it in the calendar.

The numerical attendance at all the classes, and the results of the recent annual examinations, are shown in the following table: —
The twenty-four students who require to make use of the vacation for practical mining-work have by this time most probably all found places in gold- and coal-mines in Otago, on the West Coast (South Island), and in the Thames and Hauraki Districts (North Island). The chances of obtaining employment in the latter mining fields seemed, in fact, so favourable, according to news received by some of the students, that thirteen departed together by steamer for Auckland directly after the results of the annual examinations were published. Owing to the kind intercession of Mr. James Allen, M.H.E., the general manager of the Union Steamship Company (Mr. J. Mills) made a liberal reduction in the cost of a return ticket to Auckland from £7 10s. to £5, and extended the time of return to six months—a generous aid during the pursuance of their studies highly appreciated by the students. The manager of the Huddart-Parker Steamship Company has since also intimated by letter that he will in future treat our travelling students with the same liberality as the Union Steamship Company. Eegarding the number of students likely to attend for next year's session, it may reach sixty in case all the twenty-four old students return and all new applicants for entry are admitted. The number of these latter at present on the books is thirty-two, but additional ones will very probably come forth before the commencement of next session. For the special mining classes of the first year's course —mining geology and general geology —(which are the same for all the five divisions of the school) the enlargement and alterations of the present museum room, as sanctioned by the Council, will probably afford the necessary seating-space for so large a number of students; and, if not, Professor Shand's lecture-room, being free at the hours fixed for these classes, could be made use of, though with some inconvenience in the carrying about of models, specimens, and diagrams. But for three of the classes of the second and third years' courses—viz., assaying, petrography, and surveying—twelve students at the outside (which for assaying means twenty-four, as explained previously) can only be accommodated, and only on provision for the assaying class of five newsmeltingfurnaces, and for that in petrography of at least four additional petrological microscopes and a second machine for cutting and grinding rock-sections. With regard to the assaying class last session, Mr. Fitzgerald wrote to me as follows : " I found that the laboratory accommodation was taxed to the utmost. I had sixteen students, two of whom luckily were unable to take the evening class, thus relieving the furnaces to a certain extent. I understand that five new furnaces are to be added, but I would draw attention to the fact that even with the new furnaces we could not accommodate more than twelve students in each course."

For a class of twelve in petrography, and for any larger number than this in mineralogy, an assistant demonstrator would be necessary, for the reason that in these subjects, more especially in petrography, each student requires special individual attention and instruction in microscopic examination and the preparation of rock-sections, and one man cannot possibly do this work and yet cover the ground prescribed in the calendar in the time available during the session. From the foregoing it will be seen that should, of the large number of students to be admitted for next session, more than twelve qualify for entering the session after next any of the above three classes, by passing the annual examination in mathematics and chemistry according to the Council's ruling, and the entry up to twelve goes by priority of application for entry to the school, then those above that number will have to wait for admittance to these classes till the succeeding session. Being free, however, to take other classes included in the curriculum, they can so arrange that their time for study is fully occupied during the interval. From conversation I had with many of the new applicants I found that a number of them are very deficient in necessary preliminary knowledge, and have, I am afraid, little chance of passing in mathematics and chemistry at the end of the first year's course; but, though I pointed this out to them, their intention of joining the school remained unshaken. On consideration of all circumstances, the pressure for entry to the school will most probably be confined to next session; but, should it be repeated to the same extent for the session after next, a limit would have to be placed on the number of admittances, otherwise the resources of the school in accommodation, apparatus, instruments, &c, would be totally inadequate : they would, in fact, require to be more than doubled in order to meet all the necessary demands for proper teaching. For the purpose of rendering his lectures more interesting and instructive to the students, the lecturer in general geology, Dr. Don, prepared at his own expense about two hundred lanternslides, illustrating geological features and occurrences in various parts of the world, many of them, as he informed me, being copied from the admirable reports and monographs of the United States Geological Survey. He also followed the same valuable course as last year regarding practical instruction in field geology, by making, with his students, three field excursions, of which he most liberally paid the greater portion of the expenses. The first excursion during one day took in various places of interest on the Otago Peninsula, especially the Blowhole and the limestone quarries of Sandymount, and the interesting occurrence of auriferous volcanic rock at Hooper's Inlet. The second excursion, which occupied five days during the midwinter vacation, was to Catlin's Biver and Kaitangata. At the former place three days were spent in the study of the fossiliferous beds of Cannibal Bay, Catlin's Biver, and Owaka, and of the remarkable results of marine erosion on the neighbouring sea-coast. On the return journey a day was devoted to the inspection of the celebrated Kaitangata Coal-mine and the very fine and large mining machinery connected therewith. The third excursion, occupying two days, had for its object -the study of interesting geological features around Palmerston, of the Hampden beds enclosing the celebrated Moeraki boulders— gigantic septaries, so far unique in the world—next, of the fossiliferous series of Oamaru and of the Devil's Bridge. Dr. Don, on behalf of himself and the students, expresses thanks to the General Manager of Bailways for extending the concession in railway return fares from three days to eight days, so as to allow a longer stay at Catlin's; next, to Mr. W. P. Watson, the general manager of the Kaitangata Company, for permission to inspect the mine; and to Mr. J. Shore, the mining manager, for conducting the party through the workings, and in supplying sections of the workings illustrating the faulting of the coal-measures in that district. Dr. Don and the students are also very grateful to Mr. J. Paterson, the librarian of the Dunedin Athenaeum, for permission to occupy his cottage during their stay at Catlin's Biver. The resignation of Mr. P. Fitzgerald of his post as lecturer in assaying and metallurgy again deprives this department of the school of an able and energetic teacher, who performed his duties with exactness and conspicuous success. As one of our past students he certainly sets, however, a good example by his self-confidence and enterprise in trying to better his position by entering into private practice as an expert, and taking the principal active part in an undertaking to develop some of the neglected gold resources of this province. Although the new testing plant has been specially reported on to the mining committee of the Council by Mr. W. Cutten, the lecturer on applied mechanics, under whose supervision it was erected, and also by Mr. Fitzgerald, who conducted its working since its completion, still I may be permitted to add here a few remarks concerning some alterations and additions which I consider would much improve its gold-saving facilities by amalgamation, and next in explanation of the objects of the plant —in fact, its value to the mining public. Begarding the amalgamating appliances in direct connection with the mortar-box at present in use, they consist of two silverplated and amalgamated copper-plates divided by a very shallow and narrow quicksilver riffle, and at the end of the second plate of a deeper quicksilver riffle from which the crushed material runs on to two blanket strakes. In the working it has now invariably been found that the shallow dividing riffle and the succeeding copper-plate retained but a small percentage of gold, while the deeper quicksilver riffle at the end caught a much larger quantity. This points distinctly to the advisability of interposing between the copper-plates, instead of the present shallow riffle, a so-called deep-drop riffle, say, of Sin. drop, such as are used in sets of three with great satisfaction in some of the best crushing-mills in Victoria, and in cases quite to the exclusion of copper-plates. The second copperplate would need to be only a few inches broad, and be followed by a shallow catch-riffle, following which again would come the blanket strake, some 4 ft.-5 ft. larger than at present—an addition much needed for a more satisfactory saving of pyritous material. All these alterations and additions, which I beg strongly to recommend, can easily be effected, and at but a small expense— say, about £3. Begarding the value of the plant to the mining public, it consists, in my opinion, not so much in extracting the highest possible percentage of gold from any parcel of ore sent, but rather in the information imparted to the sender in the report accompanying the gold extracted. For he will find indicated in this report, as deducible from the results of the
C—3

various assays, cyanide tests, and observations made in the course of the trial, the most advisable treatment on the large scale for ore of similar character as the parcel sent, which may be by wet-crushing and amalgamation and use of the berdan or the cyanide process for the concentrates or by direct application of the cyanide process— i.e., by dry-crushing and leaching of the crushed stuff by cyanide solution of a certain strength. There seems to be a belief amongst some OtagO mining men that the direct use of the cyanide process, as just explained, is advantageous for auriferous quartz of every description, but this is a great mistake. For the ore of most, if not perhaps all, auriferous reefs of Otago occurring in schistose rocks the direct process is quite unsuitable, and causes loss, owing partly to the general great diversity in the size of the gold particles enclosed therein, partly to its mullocky character or admixture of schistose rock. While the finest gold particles may yield to the cyanide solution in a few hours, the larger ones might require up to several days for this action, and consequently there is no limit fixablefor the time qf satisfactory leaching. And mullocky ore, or such mixed with schist, forms slimes so unctuous and impermeable that hardly any cyanide solution will filter through, even by the use of a strong exhauster. For these reasons senders of ore parcels should not unreservedly demand the use of the direct process for their ore, as was done in some cases, but leave the advisability of its application to the judgment of the operating metallurgist; for, if they do so, it stands to reason that they have to be satisfied with the results of the extraction, however unfavourable these may turn out. The work done for the public since the date of my last year's report—2sth November—by Mr' P. Fitzgerald, and since his departure by Mr. A. Mosley, in assays, analyses, and with the testing plant, and by myself in the determination of minerals and rocks, was as follows ; — ' Assays and Analyses charged at Fixed Bates.

April 5. —White mineral found at Waikouaiti, forwarded by editor of Witness, proved to be a hydrous silicate of alumina allied to halloysite. June 30.—A sample of fine black sand, forwarded by Mr. W. Motherwell, Ophir, was found to consist of titaniferous iron with a small percentage of magnetite. Two rock specimens from same district proved to be argillaceous mica schist coated with manganiferous brown iron-ore. July 17. —A sample of coal from Fortrose, sent by the editor of Witness, resembled pitch-coal, but was found to be so strongly impregnated with pyrite and to be generally so friable as to render it of very little value. July 25. —Sample of rocky material supposed to contain gold found near Oamaru, and sent by Dr. Garland, proved to be non-auriferous. August 22.—Sample of rock from Eaggedy Eidge, near Ophir, sent by Mr. W. Motherwell, and supposed to be of some value in containing gold and other metals, was found to be rather decomposed quartziferous phyllite mixed with micaceous quartz schist, all impregnated with small crystals of pyrite and magnetite; an assay gave a small trace of gold. September I.—Mineral specimens from western spur of Mount Cook, forwarded by D. M. McFarlane, S.M., Hokitika: These specimens contained in a matrix of quartz and tremolite small crystals and granular patches of a red transparent mineral, supposed to resemble the Oriental ruby once found at Rimu, but the mineral proved to be common garnet of no value. November 3.—Specimen of rock from the Inkerman Mine, Eeefton, forwarded by Mr. G. Dixon, was found to be a fine-grained somewhat feldspathic sandstone. Information and Beports on Various Subjects. (Furnished by myself without charge.) December 3.—lnformation to editor of Witness about market price of aluminium. December 10.—Information by letter to Mr. W. H. Young, miner, Hyde, about prospecting of quartz reefs.

Selby, Melbourne —regarding the occurrence and best mode of procuring scheelite in this province, to be used for the manufacture of fluorescent screens required for obtaining proper effects by means of the Eontgen X-rays. NELSON SCHOOL OF MINES. This is a school where the pupils are taught mineralogy, assaying, and elementary chemistry. The following is Mr. W. F. Worley's report on the progress made during the year: — I have the honour to report as follows on the work done in connection with the Nelson School of Mines from the 31st March, 1896, to the 31st March, 1897. Blowpipe Class. Thirty-six boys joined this class early in April, 1896. Most of these attended well till the end of the year, but after the Christmas vacation, owing to some of the boys having left school and to the rearrangement of classes, the numbers fell off to twenty. The attention of the class was directed mainly to the testing of ores and metals of commercial importance. Each boy, in addition to the ordinary blowpipe outfit, was provided with a small tin pan and some gold-bearing sand with which he practised the art of panning. The boys took great interest in the work of their class, and, for their years, made considerable progress. The class was examined on the 31st March of this year. Small quantities of lead, antimony, bismuth, chrome, copper, and manganese compounds were given to each boy, and one hour was allowed for the testing of these. To prevent mere guesswork, each boy was required to assign his reason for giving a given name to any of the test-powders with which he had been provided. There were thirteen boys present at the examination. Jesse Hill named correctly five of the minerals, and was awarded the first prize—a handsome blowpipe cabinet, presented by J. D. Hornsby, Esq. Six others named correctly four of the minerals, but owing to their thus tying were examined again with fresh tests for the honour of second place. Harold Hounsell proved the best among these, and was awarded second prize—a copy of the " Prospector's Handbook," presented by myself. Lectures. A lecture on fire-damp and choke-damp was prepared to illustrate the supposed cause of the Brunner disaster. It is not necessary for me to mention the theoretical parts of this lecture, but a description of the experiments by which it was illustrated might be useful to those who have to do with coal-mines. A large wide-mouthed glass bottle was procured, and graduated into twenty parts. The graduating was done thus : The bottle was placed on a pair of good scales and carefully counterpoised. A 4 oz. weight was then added to the weights, and water poured into the lottle till the scales again balanced. The bottle was then placed upon a level surface, and on each side of the bottle was drawn a short, thin line of red paint, just at the level of the water. This operation was repeated till the whole of the bottle was graduated. To facilitate counting the marks on the bottle each fifth mark was numbered. A tinsmith was then got to make a small Davy lamp, just large enough to pass through the neck of the bottle. The diameter of the Davy lamp was If in. and its depth 8 in. One of the three stout wires used for strengthening the sides of the lamp was pro-
0.—3-
20
longed to 18 in. to serve as a handle when lowering the lamp into the bottle. A short piece of small wax candle, such as is used on Christmas-trees, supplied the light. The candle-socket was made to fit just tight into the bottom of the lamp, and did not need any fastening. With these pieces of apparatus one was able to show the behaviour of the flame towards mixtures of air and coal-gas. The first experiment was made with one part of gas to nineteen parts of air. The naked flame of a small piece of candle attached to a wire was lowered into this mixture, and the character of the flame noted. The experiment was repeated with the same quantity of gas, but with one part less air, and the ratio of air to gas was thus gradually reduced till the explosive point was reached. This explosive point was found to be between thirteen to fourteen parts of air mixed with one of coalgas. The quantity of air was then still further reduced till the maximum amount of explosive force was reached. One of gas to nine or ten of air gave the loudest explosion. With these quantities the bottle was half-full of water, the other half of the bottle being taken up by the explosive mixture of air and gas. To get a larger volume of explosive gas two parts of gas were mixed with eighteen parts of air, and the mixture fired with a naked light. A similar mixture of air and gas was then made, and the Davy lamp lowered into it. The gas was seen to inflame within the lamp, but there was no explosion. . To show the effects of a gas explosion upon animal life the bottle was again charged with two of gas to eighteen of air; a mouse was dropped into it, and the gas fired by a naked light. The mouse was singed and stupefied, but not killed, the small amount of carbon dioxide in the bottle riot being sufficient to kill it. It was, however, quickly despatched by pouring into the bottle some ready-prepared carbon dioxide, the deadly properties of that gas being thus shown. These experiments have been described in detail, with the hope that some of those who work in coal-mines will perform the experiments for themselves, and thus learn by actual experiment the dangerous nature of the gases with which they have to deal. Many miners have not seen the faintest gas explosion ; hence the weakness of their conception of danger, and their neglect of the safeguards provided for them. Assaying. Nelson has felt the wave of the mining boom, and during the last twelve months more assaying has been done here than in any previous year. In all 149 assays were made, most of them being fire-assays for gold or silver, but a few of them were wet-assays for copper. Judging from the quality of some of the stones sent for assay, there ought to be a considerable increase in mining in this district before long. The most interesting discovery of the year was the existence of gold in some of the copper-sulphide lodes of the Dun Mountain district. The gold was first discovered in the Monster Lode, at the head of Aniseed Valley ; and later on an outcrop of gossan on Mount Claude, lying between there and the Dun Mountain, was also found to carry gold. The assay-value of these lodes is not high, but is sufficiently good to warrant extensive prospecting. Appended is a schedule of the assays from that district: — Copper-sulphide (Monster Lode) — Gold. Copper, i No. 1 assay ... ... ... 4 dwt. per ton. Not estimated. No. 2 „ ... ... ... 2 No. 3 „ 8 No. 4 „ ... ... ... 4 No. 5 „ ... 5 No. 6 „ ... ... ... 4 No. 7 „ 4 No. 8 „ ... ... .. 6 „ 4-08 per cent. No. 9 „ ... ... ... 4 „ 3-48 ,; •• Copper-carbonate, &c.

In addition to the assaying, several pan tests and blowpipe tests were made, a few only of which call for special mention. Some black sand from the Moutere Hills was found to consist largely of grains of chromite. This is an interesting geological discovery, as it proves that the mineral belt was being denuded at the time the materials of which the Moutere Hills are composed were being deposited. Some black sand from the upper part of the Motueka River gave, in addition to iron, reactions for nickel, but the test was not decisive. A visit to the Moutere Hills proved conclusively, by several pan tests, that that formation is gold-bearing, though nothing approaching payable stuff was seen. Some of the sedimentary rock from the district of the Enner Glynn Coal-mine was also found to contain traces of gold. These facts seem to indicate that a lead of payable gold might be found if properly prospected for.

Conclusion. " Owing to so much of my time being taken up with assaying I was unable to hold any classes for adults, though several persons were anxious to join classes. With the limited amount of spare time at my disposal, even the assaying was rather too much for me, and I was obliged to employ labour for the rougher parts of the work. My laboratory is extremely small, and I have not yet been able to afford the laying-on of water. Gas for roasting purposes and small fusions was laid on about the middle of the year, at my own expense. In studying the rocks of this district I am badly in need of a petrological microscope, and hope before the end of the year to receive some assistance in purchasing one. EXPENDITURE ON SCHOOLS OF MINES. The following table shows the expenditure by the Government on Schools of Mines since their inauguration, exclusive of subsidies paid to the University of Otago towards the School of Mines in connection with that institution :—
The above statement shows the amount expended on the different Schools of Mines throughout the colony; but, in addition to this, the sum of £6,250 has to be added, as that has been paid to the School of Mines attached to the University of Otago, £1,000 being paid last year towards maintaining the school and erecting additional plant, which makes the total expenditure up to the 31st March last to be £22,920 9s. 2d. This expenditure has extended over a period of twelve years.
WATEE-EACES. Waimea Water-race. ~ ■- The deviation of this race is so far advanced that the water is now run in the open ditch. There is still a section of low fluming, about 11 chains, to be constructed to receive the water from the ground-race, and when this is completed the whole of the high fluming will be dispensed with. The sound timber available from the old high fluming is used where practicable in the construction of the low fluming connecting with the ditch. The whole of the timber in this fluming is 7 silver-pine, and will last for forty years in good condition. A great saving in the cost of maintenance is now effected, the old fluming having taken a great deal of labour and material to keep it serviceable. On the whole, this may be looked upon as a work of great importance to the, miners, as there is now less chance of breakages in the race, and consequent loss of time in carrying' on sluicing operations. The amount expended on this work was £1,512 lis. Id. during the year. The branch race to Callaghan's has been completed, and water supplied to the miners during the months of February and March. The amount expended was £329 7s. Id. during the year. No work has been done On the branch race towards the middle branch, Waimea Creek, as no water can be used from it until the completion of the Waimea Main Tail-race. When this is completed about 80 chains of race will have to be constructed to supply water to the claims which the tail-race will command. This new main tail-race has been driven a total length of 2,100 ft., and the trustees are about to sink a shaft to connect with the surface in the large flat on the middle branch of the Waimea Creek. When the communication is made the tail-race will be paved with wood blocks, and several parties are ready to drive branch tail-races to connect with the claims, so that in a short time it will be available for use. The Kelly's Terrace drainage-tunnel has been driven 1,200 ft., and, as the country through which the tunnel is being driven is auriferous, it is probable that payable gold may be struck before the intended termination of the tunnel 6,600 ft. from the entrance is reached. It is expected, therefore, that water will shortly be required to work the ground opened by both the tail-race and the drainage-tunnel. The following statement will show the receipts and cost of maintenance of the Waimea Eace" for the year ending the 31st March last, together with the approximate quantity of gold obtained by those using water for working claims from that supply : —

It will be seen from the foregoing statement that the value of the sales of water for the year amounted to £776 19s. 5d., as against £795 13s. 6d. for the previous year, while the cost of maintenance amounted to £669 6s. 3d., as against £770 3s. Bd. for the former year; thus showing a decrease in the cost of maintenance of £100 17s. 5d., and also a decrease in the value of the sales of water of £18 14s. Id. from the previous year. The average number of men employed in claims worked with water from this supply last year was 6625, and the approximate quantity of gold obtained by them was 2,133 oz., representing a value of £8.318 14s. Deducting the value of the sales of water from the value of the gold obtained, it leaves the average earnings of the men to be £113 16s. 9d. per man per annum, or £2 3s. 9d. per man per week. This cannot be taken as their actual earnings, as the cost of pipes, tools, and timber required in working the claims has also to be taken into consideration. The value of free water given to open up claims and for working poor ground during the year was £100. This free water, however, is necessary, as the ground is becoming more expensive to work every year. The total cost of this water-race and branches up to the end of March last was £136,340 18s. 7d. Callaghan's Branch Water-race. This race has been completed at a total cost of £5,948 18s. Bd., and the miners in this district have been supplied with water since the beginning of February. The anticipation formed that this race will become of importance is shown by the returns obtained from the use of the water from this supply : —
It will be seen from the foregoing statement that the value of the sales of water for the past two months amounted to £42 155., and that the cost of maintenance was £25 15s. The average number of men employed was 12-5, and the approximate quantity of gold obtained by them was 110oz., representing a value of £429. Deducting the value of the sales of water from the value of the approximate quantity of gold obtained, it leaves £386 ss. as the earnings of the miners, which is equal to an average of £30 18s. a man for two months, or at the rate of £185 Bs. each per annum. Kumara Water-race. This race still continues highly profitable, although the gold obtained through the use of this water-supply does not come up to past returns. The richer claims are becoming worked out, and, as far as known, the large area of auriferous ground that has been proved is found to require working on the most economical principle in order to remunerate those employed. An extensive area exists that will afford employment for a number of miners for many years to come. Future workings will be more costly, both on account of the limited fall for tailings and also the greater quantity of water required to remove the poorer layers of gravel. The whole of this race is in good repair, the Kapitea Hill Eace, in addition to the ordinary demand, having supplied water required in the construction of No. 4 and also of No. 5 main tailraces, the cost of the water to supply No. 4 being £106 9s. 3d. and for No. 5 free water. The by-wash of the Loop-line Dam is being raised. This will have the effect of largely increasing the storage-capacity of the reservoir. Another catchwater-race, which can be constructed at a reasonable cost, will further improve the supply for this dam, and the loss from scarcity of water be thereby reduced. The No. 5 main tail-race is not yet completed. The total length will be 6276 chains, of which 40 - 27 chains has been constructed, being securely timbered, boxed, and blocked; and there still

remains 22-49 chains to complete the driving of the tunnel. When this is completed a large quantity of water will be required to work the different claims. The total amount paid by subsidy for this work was £2,463 ss. 9d. The following statement will show the revenue derived from sales of water, and also the cost of maintenance, for the year ended 31st March, 1897 : —
It will be seen from the foregoing statement that the value of the sales of water for the past year amounted to £3,502 175., as against £4,106 lis. 3d. for the former year, and that the cost of maintenance was £1,786 15s. 9d., as against £1,943 Bs. 7d. for the previous year. This shows a decrease in the revenue last year of £603 14s. 3d., and a decrease in the cost of maintenance of £156 12s. lOd. In addition to the sales of water, the value of free water supplied to the claims which did not prove payable to work during the year amounted to £613 os. 6d. The average number of men employed in claims worked with water from this supply was 90-33, and the approximate quantity of gold obtained by them was 5,455 oz., representing a value of £21,264 10s. Deducting the value of the sales of water from the approximate quantity of gold obtained, it leaves £17,761 13s. as the earnings of the miners, which is equal to an average of £196 12s. 7'4d. a man per annum, or £3 15s. 7-Jd. per man per week. The total cost of this work up to the end of March last amounts to £41,463 165., and, deducting the cost of maintenance from the value of the sales of water for the year, it leaves a profit on the working of £1,716 Is. 3d., which is equal to 4-137 per cent, on the total cost of the works. The reason the sales of water amount to so much less than last year is that the price of water was reduced from £2 per sluice-head per week to £1 10s. from the Ist June, 1896, so that there was only two months of the year at the higher price. [For table showing result of working Kumara Water-race for fourteen years, see page 25.] Waimea-Kumara Water-race. The Waimea and Kumara Water-races have been considered as separate races, though this is not the case. The object of showing each separately is to give an idea of the value of each in proportion to the capital expended on the different works in connection with each branch. They may be termed separate water-races, but the supply of water to the Kumara branch is dependent to a great extent on the Waimea branch. If these races were held by different individuals there would be a far greater scarcity of water at Kumara than now occurs, and at the same time there would be more water in the Waimea Eace than could be disposed of. However, when the deviation of the Waimea Water-race is completed, and the branch constructed to Goldsborough, the whole of the water in that supply will be utilised at Callaghan's and the middle branch, and it will only be when there is surplus water in the Kawhaka Creek that there will be a full supply in the Kawhaka Eace feeding the Loop-line Dam, which stores the water for the Kumara field. The whole of these water-races are under one management, and worked as one concern. The following statement will show the revenue and expenditure on the whole of these works for the year ending the 31st March last: —

It will be seen from the foregoing statement that the value of the sales of water for the year amounted to £4,322 lis. 5d., while the expenditure for maintenance for the same period was £2,481 17s. For the previous year the value of the sales of water was £4,902 4s. 9d., and the expenditure £2,713 12s. 3d. This shows that there was a decrease in the revenue last year to the extent of £579 13s. 4d., while the cost of maintenance has also decreased to the extent of £231 15s. 3d. The total value of free water given to the miners to open up new ground and construct new tail-races, and also for working claims which did not prove payable, amounted for the past year to £819 9s. 9d. The number of men employed in claims worked with water from these supplies was 15783. Deducting the value of the sales of water from the approximate value of the gold obtained from claims worked with water from these supplies, which amounted to 7,698 oz., representing a value of £30,012 45., it leaves £25,689 12s. 7d. as the average earnings of the miners, which is equal to about £162 16s. per man per annum. The total cost of the whole of the works, including the extension to Callaghan's, up to the end of March amounts to £184,696 6s. 4d. The following statement will show the receipts and expenditure for the last twelve years, ending the 31st March last, of the Waimea and also the Kumara Water-races : —
This table shows that there has been a net profit derived from the working of the Waimea Eace of £3,723 15s. 10d., and £51,584 Bs. from the Kumara Eace, for the above period.

Mount Ida Water-race. This race has been used continuously, in consequence of the open season, the water being stopped only twenty-three days, on account of frost. The supply of water was, however, limited, On account of the exceptionally dry weather throughout the summer months, the race, at its best, only supplying twelve sluice-heads, and sometimes the quantity was reduced to five sluice-heads. As increased attention is being directed to work the deeper ground by hydraulic sluicing additional water will be in request. This will necessitate widening the race and maintaining additional storage. The Eweburn Eeservoir, which would be of vast importance in this respect if

H is found practicable to construct it efficiently, will be fully reported on by the officer appointed to report on water-conservation generally. The staff required to maintain and look after this and the Blackstone Hill Eace consists of the manager and six men. The following statement will show the revenue derived from the sales of water, the maintenance, and the approximate quantity of gold obtained by the miners using water from this supply for the year ending the 31st March last : —
It will be seen from the foregoing statement that the value of the sales of water last year amounted to £1,333 lis. 6d., as against £1,189 Is. for the previous year, which is an increase of £114 10s. 6d., while the expenditure on maintenance was £1,316 15s. 6d., as against £1,363 Is. for the previous year. The gain on the working last year was £16 16s. The approximate quantity of gold obtained from claims worked with water from this supply was 3,157 oz., representing a value of £12,154 9s. ; and the number of men employed in these claims averages about 66-5. Deducting the value of the gold obtained from the value of the sales of water, it leaves £10,820 17s. 6d. as the earnings of the miners, which is equal to about £162 14s. 4d. a man per annum, or about £3 2s. 7d. a man per week. Blackstone Hill Eace. This race continues to be economically managed, only a small amount being required for maintenance. The branch race from the right-hand branch of Hill's Creek was cleaned out in May, 1896. The dry season had the effect of lessening the ordinary supply of water during the past four months, and the race will have to be trimmed and cleared out next spring. The following statement will show the revenue derived from sales of water, the cost of maintenance, the number of men employed in working claims by the aid of this race, and the approximate quantity of gold obtained from claims for the year ending the 31st March last : —
It will be seen from the foregoing statement that the sales of water for the last year amounted to £115 19s. 3d., as against £136 lis. 7d for the previous year, while the cost of maintenance was £5 Bs. 6d., thus leaving a net profit of £110 10s. 9d. on the working of this water-race. The average number of miners employed in claims worked by the aid of this water-race was 8-75, and the approximate quantity of gold obtained by them was 183 oz., representing a value of £704 lis. Deducting the value of the sales of water from the value of the gold obtained, it leaves £588 lis. 9d. as the earnings of the miners, which is equal to about £67 ss. 4d. per man per annum. The total cost of this water-race was £1,036 16s. The net profit on the workings last year gave about 10-6 per cent, interest on the capital invested. s—o. 3.

SUMMARY OF WATER-RACES. The following statement will show the profits and losses of working the different water-races constructed and maintained by the Government for the last nineteen years, and also the collateral advantages derived by the utilisation of the water from these races: —
GOLD- AND SILVBE-MINING. The mining boom which commenced in 1895 continued throughout the past year. A large number of areas were taken up within the principal mining districts of the colony, and extensive works undertaken in prospecting and development of the mines. In a great number of cases the claims have been disposed of to English companies. Operations have been commenced and machinery erected to an extent only possible by large expenditure of capital. The demand on the part of investors for legitimate mining properties has not to any great extent been lessened, notwithstanding the shrinkage in the yield compared with last year, and shown in the following statement of the quantity and value of gold entered for exportation : —
In the Auckland District; in the North Island, there was a decrease of 23,153 oz. of gold—from Coromandel County, 12,849 oz.; from Thames County, 5,113 oz. ; from Thames Borough, 1,998 oz.; from Piako County, 19 oz. ; and from Ohinemuri County, 3,172 oz. In the South there was an increased yield of gold in the following counties, as follows : Waimea, 96 oz.; Westland, 152 oz.; Kumara Borough, 65 oz.; Taieri, 974 oz. ; Waikouaiti, 84 oz.; Lake, 514 oz.; Fiord, 2,703 oz.; Southland, 1,043 oz.; and Stewart Island, 18 oz. Last year there was a decrease in the yield of gold from the following counties : Marlborough, 2,384 oz.; Collingwood, 1,347 oz.; Buller, 2,012 oz.; Inangahua, 14,312 oz. ; Grey, 1,258 oz.; Hokitika Borough, 505 oz.; Boss Borough, 303 oz.; Tuapeka, 1,196 oz.; Vincent, 472 oz.; Maniototo, 725 oz.; Waihenio, 1,187 oz.; Waitaki, 22 oz.; Bruce, 119 oz.; Wallace, 1,229 oz.; and Clutha, 4 oz.

The decrease in the yield is not altogether due to the scarcity of the metals, or to the mines being exhausted, but chiefly to the fact that on English companies becoming owners a change in the policy of working was adopted, and dead-work and improvements in machinery carried on in the place of continuous production; to which may be added the scarcity of water during the dry season, a full supply being necessary to almost every kind of mining operations. An immediate increase in the returns cannot be looked for, inasmuch as, in addition to preliminary work, the new appliances adopted and the construction of the water-races will take a considerable time to complete, during which the actual recovery of gold in many of the mines will be almost totally suspended. In the newer mines also, in which discoveries have been made of a promising nature, gold returns cannot be expected until the mines are developed and the necessary machinery and appliances provided, both for the quartz lodes in the North and Middle Islands and the alluvial deposits in the latter Island. In the near future, however, the number of gold-producing mines will be materially increased, and a steady yield maintained. QUABTZ-MINING. The great interest evinced in quartz-mining, and the large amount of capital now invested, will mark a new era in the history of the industry in New Zealand. The introduction of capital and consequent change of policy in the development of both new and old mines has brought about a material change. The adoption of improved machinery capable of dealing with large quantities of what is termed low-grade ore will do away in a great measure with the past method of selecting only the richer portions of the reefs for quick returns. In order to maintain the supply to keep the mills employed systematic working of all parts of the mine simultaneously will be carried on, and the mines thereby made to maintain a fair average return. The mines are being opened up, and a stock of ore kept in reserve, so that when development work is going on there will be no difficulty in keeping up the output of a quantity of payable ore for treatment. During the year a large number of special claims and licensed holdings have been taken up in the principal mining districts throughout the colony. In most cases these have been acquired with the view of submitting them to agents on the outlook to purchase mining properties for the purpose of flotation of companies on the London and other markets. In many instances arrangements have been made and capital subscribed for the development of the quartz reefs, but in a great many cases the land taken up has failed to attract the representatives of capital, and the owners are left with claims they are unable to work for want of funds. In the rush to secure properties land has been acquired where at present there appears very little chance of valuable discoveries being made, and where no indications warranted the preliminary expenditure required to secure a title; many of these areas will in due course be abandoned, and the owners be losers of the money laid out in taking up the land. The investment of capital in mining enterprise, if injudiciously directed, will react on legitimate ventures, and agents should exercise caution, and become possessed of such knowledge as can only be gained from those experienced in the different fields, before recommending the expenditure of capital. In this matter I can reiterate the remarks made by Mr. H. A. Gordon in his report to you of last year: "Nevertheless, although we want foreign capital to develop the quartz-mining industry, it is essential that nothing but legitimate mining enterprises be offered to capitalists, in order that they may receive a fair interest on their outlay. If worthless properties are placed on the London market and taken up it will tend to bring about a depression in mining, and it will take a long time to re-establish confidence. All those who are interested in the welfare of the colony should set their face against offering valueless properties to foreign capitalists." There are numerous places in which highly-profitable returns on the capital invested for bond fide mining purposes can be assured, and care must be exercised in placing before investors a true report of the value of any property on which expenditure of capital is invited. In this way only can a distinction be made between those ventures that will be genuine or otherwise. At this early stage of occupation, and until actual work has for some time been carried on, it may be injudicious and invidious to definitely assert in which claims gold or silver is to be found in paying quantities. There are certain localities, especially in the North Island fields, where, in the vicinity of mines with a past history, and within the belts of well-known auriferous country, mining ventures have the greatest chance of success. To the Middle Island fields the same remarks may apply. There are, however, new discoveries taking place at a considerable distance from the localities already famous for gold-producing, and all fresh fields have for the miner sources of attraction, in the hope that the yields from the older gold-bearing reefs may be eclipsed. The prospector, therefore, goes far from the beaten track, and in many instances has obtained evidence of auriferous reefs which promise to become before long a valuable addition to the field of legitimate investment. The treatment of the ores and the recovery of the metals by the most improved methods is still being energetically pursued, and new plants will shortly be brought into operation on the fields of both Islands. The following list of companies outside the colony connected with New Zealand mining shows the vast interest taken in developing the industry, and before long investment in mining will be in the front rank amongst the other commercial undertakings throughout New Zealand : —

NORTH ISLAND. Puhipuhi. The most northerly field in the Auckland District is at Puhipuhi. The locality of the reefs already discovered is in the vicinity of the Table-land, or flat top of the main range. There is, however, a tract of country between this and Helena Bay which is known to contain quartz reefs, but has hitherto not been sufficiently prospected on account of its rugged and broken nature and the dense bush with which it is covered. In the older worked portion of the field too much has been expended in experimenting with different modes of treatment, whilst exploration of the ground and opening up and prospecting reefs have been neglected. It would be wiser to ascertain what extent of ground is available, and how far the reefs and lodes may contain the metals, and what would be the value per ton, and demonstrate without doubt that sufficient quantities of ore can be readily got at, than to erect machinery and afterwards find that there was not sufficient value in the ore to cover the cost of mining and treatment. The possibilities of the district are very great ; the large reefs already discovered and the character of the quartz, which in most eases carries gold and silver, show they are worthy of being thoroughly tested. It only requires a discovery of undoubted payable quartz to give an impetus to the prosecution of prospecting. The mode of treatment suitable will soon follow when the presence of valuable ore in question is determined. The following abstract shows the land held for mining purposes in this district: —

The attention directed to taking up land for mining throughout the Hauraki Mining District led to a considerable area being again occupied in this district. British Gold- and Silver-mining Company's Mine (Area, 600 acres). —Very little mining work was carried on during the year, the whole of the company's attention having been devoted to the erection of the chloridizing roasting-kiln, and transforming the battery for Mr. French's new process. After the battery and kiln were used for a short time operations ceased, and the mine was closed down. The proceeds of Mr. French's treatment cannot be obtained, as he, shortly after making a trial of the plant, left the district. It appears that all the capital of the company was exhausted in prosecuting Mr. French's experiments, and the directors are endeavouring to induce the representatives of capital to find sufficient funds to work the mine. Dr. Jim Mine (Area, 200 acres). —This mine comprises the Dr. Jim and Cecil Ehodes Claims, and is situated next the British Company's Mine, in the north part of Puhipuhi Forest. About 200 ft. of driving has been done in the mine, as well as surface prospecting. Four men were employed up till the time the claims were protected. As this company has no machinery it is intended to try some of the ore in the British Company's battery before erecting a plant. There are four reefs, from 3 ft. to 8 ft. in width, in the ground carrying sulphide of silver. Work has also been carried on in the New Puhipuhi, Waimarie, and other claims; sulphide of silver is found in the quartz, but so far it has not been demonstrated to be present in payable quantity. A considerable amount of attention was directed to the Kauri Mountain, near Whangarei Heads, where gold has been obtained in small quantities in veins and leaders. Another discovery has been made of a large so-called auriferous dyke, said to be from 100 ft. to 150 ft. in height, and from 300 ft. to 400 ft. wide, where it projects into the sea. If gold exists throughout such a large mass of material a very small yield per ton would be payable, as the stuff could be cheaply mined. Ohaeawai. A certain amount of machinery was erected for the treatment of the mercury deposits at this place, but no results have been obtained. Prospecting was occasionally carried on, and a goldbearing leader discovered at Pukepokako, on the road to Kirikiri, but so far there has been no valuable result. Throughout the Bay of Islands County occasional discoveries of quartz have been made, and on several occasions I have received samples collected by Captain Stephenson, but there appears to be a decided absence or only slight traces of the precious metals in the tests made. Geeat Baebieb Island. Great Barrier Island lies about fifty-seven miles north-east of Auckland, being the largest of the belt of islands in and north of the Hauraki Gulf. It is about twenty miles long, is ten miles across at the widest (from Owena to the mainland near Eangianua) and three miles at the nearest part (from Oruawharo to Blind Bay). The country is very rough, from Kaitoke Valley to Harataonga particularly, the Hirakimata (Mount Hobson) Eanges intervening before the Awana Block, known also as the antimony property, is reached. There is plenty of kauri on the island, a large portion of which is the property of the Kauri Timber Company, while manuka and fern render travelling to any point past Kaitoke Creek somewhat difficult. The scenery is splendid, there being a wild grandeur which cannot fail to please. A bullock-track runs as far as the lona Mine, and a horse-track leads from Blind Bay through nearly all the mining properties, and these will shortly be followed by a road from Blind Bay to Whangaparapara Bay which can be negotiated by vehicles—a thing impossible at present. The First Discoveries of Gold and Silver. As may be expected, a good deal of controversy has taken place regarding the question as to who first discovered valuable minerals on the island. It is alleged that as far back as 1857 a miner named James Perry prospected the northern end and discovered antimony and copper and slight traces of silver, but very little attention was paid to the matter at that time. This statement is doubted by many old residents of the island, who state that it is only a few years back since prospecting was properly carried on. Twelve years ago, however, the property now known as the Awana Antimony-mines was prospected by Arthur T. Lee and A. Prescott. Two years later Lee accidentally found stone showing antimony at the head of the Awana Creek, below Hirakimata, on the eastern side. He was subsequently despatched by an Auckland syndicate, of which Messrs. W. F. Buckland and Charles Clayforth were the head, to cut the antimony lode which was supposed to exist on the property. This was done, and some good specimens taken out and forwarded to Auckland. For several years members of the Sanderson family, who have resided on the island, a* Tryphena and Blind Bay, for thirty-two years, have prospected various portions, particularly that in which the mines at present being worked are situated. Six years ago Ben and William Sanderson prospected White Cliffs, but it was twelve months before they struck what was considered payable ore. On the property now known as the Original (previously called the Prospectors' Union Jack), on the Great Barrier, Kauri Timber Company's property near Whangaparapara, and on Eyan's freehold good prospects were obtained. The party pegged out the Original, and worked it for two years, putting in two drives and cross-cutting. Some 14 tons of stone were taken out and treated, the return of bullion being considered very satisfactory. Work was continued for a short time, and abandoned on account of the patchy nature of the ground. When the mining boom was at its height attention was again directed to the Great Barrier, and there has been a marked revival in mining during the year. Work was carried on in the original Great Barrier Claim, which was exploited by the Anglo-Continental Syndicate, who held an option over the mine. After several months had been spent in prospecting

C,~-3
and various reefs driven on, this syndicate gave up the option, and the land reverted to the owners. On the inclusion of this island in the Hauraki Mining, District, on the Ist September, 1896, the owners of the prospecting licenses secured titles under the Mining Act, and the following special claims were applied for and granted by the Warden at the Thames on the 30th November, 1896 :—
Abstract of Licenses for Special Claims, issued from the Warden's Office at Thames, in the Great Barrier Island, and registered on or before the 31st March, 1897, in the Books of the Mining Registrar, Thames.
As soon as titles were completed work was vigorously carried on in the following mines :— Original Great Barrier Mine (Area, 200 acres). —In addition to the prospecting and development work done by the Anglo-Continental, the owners have commenced to drive a level 1,150 ft. to cut the reef at a depth of 120 ft. below the surface. There are four reefs in the ground, varying from 3 ft. to 5 ft. in width, and carrying gold and silver in sulphide form. A drive was also made on No. 1 reef, 80 ft., and another on No. 2 reef, 50 ft. Seven men are employed. Aotea Mine (Area, 200 acres). —A level has been driven a distance of 90ft., with a view of cutting the Proprietary reef. Trenching has also been done on the surface. lona Mine (Area, 200 acres). —A drive has been put in 150 ft., and a large reef about 12 ft. in width cut into. The quartz is generally of a hard flinty nature, containing gold and silver. Five men are employed. Kaitoke Mine (Area, 200 acres). —A level has been driven 123 ft., to be extended to cut the lona reef, near the southern boundary of the claim.- Three men are employed. Great Barrier Mine (Area, 200 acres). —There are a number of reefs running through this ground ; only two, however, are at present being worked. Lee's reef has been cut and driven on 100 ft. in the top level, and a cross-cut is being put in to cut it at a depth of 80 ft. under the top level; another cross-cut is also being driven to cut the reef to the eastward, of the present workings. Lee's reef is about 18 in. in width, and the ore is of a rich character : 1 ton gave a value of £15, and a parcel of 10 tons has been shipped for treatment at Swansea. The lona reef runs through this ground, and a cross-cut is being driven to cut it. Twenty-five men are employed in this mine. Mount Argentum Mine (Area, 200 acres). —A low-level tunnel has been driven 250 ft. to cut a reef about 12 ft. in thickness. Several other smaller veins were cut, in which a trace only of silver was found. Seven men are employed. Prospecting has also been carried on in the Edgerton, Excelsior, Bonanza, Comstock, and other claims. Byan's Freehold (Area, 80 acres). —Mr. A. McKay, Government Geologist, who has recently visited the island, describes this property as follows : " This is the area contiguous to the Great Barrier, on its western boundary, the reef from which passes into Eyan's Freehold at the waterfall, in the bed of the creek. In this the reef has been explored west a distance of 60 ft. The ore-band is continuous, and at the upper level shows a thickness varying from 12 in. to 15 in. or 18 in.; 15 in. may be considered the full average thickness of the lode in this part of its course. The ore is richer here than in the Great Barrier Claim, and magnificent samples might have been collected from the heap when the mine was visited. At that time a winze was being sunk to cut the lode at a further depth of 25 ft. to 30 ft. This has now been done, and it is reported that in the winze the lode shows 30 in. in width, carrying ore quite as rich as may be had from the upper level. A low-level adit is contemplated, which may be made to cut the lode 70 ft. to 80 ft. below the present workings, and at which it is hoped the thickness of the lode will be further increased. Many tests on small samples of the ore have been made, leading to the conclusion that the value of the ore is not less than £36 per ton, and from the character of the ore coming from the mine at the time of my visit the above seems to be a very moderate estimate of what the average yield will be should the ore continue of the same grade. A sample analysed at the Thames School, of Mines yielded at the rate of 500 oz. silver to the ton. The country on the foot-wall of the lode within Eyan's Freehold is fairly well decomposed to a kindly-looking ' sandstone,' but this will probably not continue to any great depth,

the foot-wall in the winze being very hard andesite; so that anticipations of the presence of soft country along the western part of the lode are of doubtful realisation. There is ample warrant for the energetic prospecting of this lode in both claims in which it has been traced, and the ore is rich enough to pay for transit to Europe for treatment. Its richness, therefore, to some extent compensates for the smallness of the lode, and in this particular has to be looked at favourably in comparison with the greater mass and poorer ore of the lona lode." In order to afford facilities for working the mines in this district a road is being made from Blind Bay to Whanagaparapara. Attention has again been directed to the reefs containing copper-ore which were formerly worked in the northern part of the island, but very little work was done during the year. COEOMANDEL DISTEICT. The district comprises the northern portion of the peninsula. The country is of a very broken and hilly description, covered chiefly with bush, although in several parts the kauri timber has been removed and clearings effected. In consequence of the continuous rich yields from the Hauraki Mine numbers of claims were taken up, as the subjoined list will show. A large amount of prospecting has been carried on, and many discoveries of gold-bearing reefs were made. It will, however, take a length of time to develop the mines and to ascertain the value of those discoveries, and no doubt in many cases the claims will be abandoned for want of funds to carry on operations.

Port Charles District. Jay Gould Mine (Area, 100 acres). —Situated at Big Sandy Bay. Three drives have been put in —No. 1, driven 76 ft., on Kensington's reef, a small vein about 4 in. in width, in which small prospects of gold can be got; No. 2 drive is a cross-cut which is being put in to cut Mclsaac's reef; No. 3 level has been driven 64 ft. to cut No. 2 reef, which varies from 10 in. to 18 in. in width, and also gives small prospects of gold. Pour men are employed. A small amount of prospecting work was done on the De Hirsch Claim, of 99 acres 3 roods, but no gold has been reported. The Takapuna, Golden Gate, Vanderbilt, Grand Moehau Freehold Syndicate, Pacific, and Mclsaac's have been also taken up, but no returns have been made. Cabbage Bay District. White Star Consolidated Mine (Area, 750 acres 1 rood 31 perches).—This mine comprises the following claims : Doric, lonic, Coptic, Celtic, Britannic, Noric, Helvetic, and Belgic. Seven or eight prospecting drives have been put in, chiefly near the surface, and several compact quartz reefs cut in andesite country. Small leaders were also cut in the slate formation. A low level has been commenced to cut the reef, which occurs in the Belgic and Coptic Claims at a depth of 120 ft. below the surface. Twenty-four men are employed. Golden Caledonia Mine (Area, 27 acres). —As many as nine reefs occur in this ground, varying from 6 in. to 8 ft., but only in two of them has gold in small prospects been got. Three men are employed. Ladas Mine (Area, 87 acres). —Surface trenching was done for 110 chains, and seven different reefs cut, varying from 6 in. to 3 ft. 6 in. A cross-cut was put in 200 ft. below the surface, and a reef cut at 94 ft. Another drive is put in 50 ft., but no reef cut. Four men are employed. Queen Victoria Mine (Area, 100 acres). —A small parcel of 2 tons of oxidized pug and 1001b. of hard quartz was crushed at the Moanataiari Battery, Thames, for 3oz. of gold, value £2 15s. 6d. per ounce. The following is the work done at the mine during the year : About 205 ft. of driving, 300 ft. of trenching, 30 ft. of old drive cleaned out and repaired. There are several leaders, and three of them gold-bearing. Four men are employed. Criterion, late Fortuna Mine (Area, 47 acres 2 roods 28 perches).—This mine is situated at Waikanae, and the reef, which last year yielded quartz worth 10 oz. 3 dwt. to the ton, has again been worked. A parcel of 8 tons 3 cwt. of quartz was crushed, for 104 oz. 2 dwt. of gold, and 5 tons of quartz from No. 2 reef yielded 9 oz. 15 dwt. of gold. As there are several other goldbearing reefs in the ground the prospects are considered favourable, and a battery is to be erected convenient to the mine. Six men are employed. The City of Gisborne, Jersey, Cuvier Light, and Elvira have been prospected and reefs and leaders of quartz discovered, but no returns of gold have been made. Fortuna No. 2 (Area, 38 acres). —A considerable amount of prospecting work has been done. Six different cross-cuts were put in, and in the quartz cut prospects of gold are got, but not of a rich character. Four men are employed. The Moehau Nos. 1, 2, 3, and 4, Killarney, Golden Fortuna, Baron Eothschild, Netherfield, Great Waikanae, and Everton have also been prospected, but no results furnished. Kennedy Bay District. The A.J.C. Special Claim, of 100 acres, is situated at the Omoho Creek, Kennedy Bay. About 200 ft. of driving has been done, and three reefs discovered, each of which yields prospects of gold. Pour men are employed. Lorna Doone Mine (Area, 100 acres). —A considerable amount of work has been done in prospecting the reefs in this mine. Eight reefs are known, varying from 2 ft. to 5 ft., and one large reef 40 ft. in width. Gold is found in No. 3 reef and in the 40 ft. reef by pounding the stone and using the dish, but so far none of the reefs are valuable. A cross-cut is being put in to cut No. 3 reef at a further depth of 60 ft. Five men are employed. Work was also carried on in the Bay View, in which several reefs, varying from Ift. to 4 ft., have been discovered. A parcel of 6J tons yielded 19 oz. 8 dwt. of gold. The Madge, Look-out, Evening Star, Anglo-Saxon, and Maioro have been prospected, and in each quartz reefs were found. In the Kennedy Bay, Vanderbilt, West Derby, and Eangipuhi no discoveries have been made. Paul's Creek District. Conquest Mine (Area, 30 acres). —Considerable prospecting was done near the surface, but the ground opened proved to be of a loose disturbed character. A low level is now being driven to test the firm country underneath. Golden Lead Mine (Area, 127 acres) .• —About 300 ft. of cross-cut driving has been done, and several reefs cut; value not known. Five men are employed. The Duke of Wellington, Kapanga Beefs, and Corea Claims have also been prospected. Tokatea District. Boyal Oak and Tokatea Mines. —These mines are adjacent, and situated on the Tokatea Range. A large reef runs along the range in a northerly direction near the ridge, and the principal workings are on the eastern slope, the reefs worked being offshoots of the main reef, and running nearly at right angles to it. An interesting feature, and one that renders the deeper workings in these mines a matter of the utmost general importance, is that the reefs have been worked from the surface downwards in andesite rock; but at the lower levels the rock is changed to slate or sedimentary

rock. The chief gold-production from the Hauraki Mining District has been from those reefs existing in the andesite, and in few instances have reefs in slate formation hitherto proved payable. Therefore, as it is now proved that the veins of quartz have an uninterrupted continuance downwards in both rocks, and that they are gold-producing to a depth of 100 ft. below the adit, it augurs well for the continuance of the reefs down into the slate formation in all the other portions of the Hauraki Goldfield, and gives hopes of success in deep-level mining throughout. Captain Hodge has furnished me with the following report on those mines which are under his control: — Boyal Oak cf Hauraki (Limited). —This company has an area of 39 acres 1 rood 9 perches. The number of persons employed by the company is forty. The total expenditure since registration to the 31st December has been £8,221 os. Id. The greatest depth reached below the surface in this company's property is 930 ft. The number of levels in which work has and is being conducted is four—No. 3 level, 385 ft. below surface ; No. 5, 442 ft.; No. 6, 693 ft.; and No. 7, 869 ft. The shaft is also sunk below No. 7 level about 70 ft. The reefs being developed are known as the No. 1 tribute leader, in the Oak section, which averages 1 ft. wide; the Main Tokatea reef, averaging from 12in. to sft. wide; while the trunk reef of the district varies from 50ft. to 80ft. wide from wall to wall. The company has crushed since registration 36 tons of quartz, yielding 350 oz. 19 dwt. of melted bullion, and realising £884 19s. 9d. It is the intention of this company to thoroughly develop the Oak section of the property, and, in conjunction with the adjacent company— the Tokatea—by the aid of that company's machinery and motive-power, to develop the Main Tokatea reef, that paid so many dividends, and of which this company owns a section. Tokatea of Hauraki (Limited). —This company owns an area of 75 acres 2 roods 2 perches. The greatest depth reached from the surface or crown of the hill to this date is over 1,000 ft., on the line of the famous Main Tokatea reef, which reef contributed largely to pay the old Tokatea Company in dividends between £60,000 and £70,000. I may say it is satisfactory to find this reef carrying strong dabs of gold in the stone all along the bottom of the 100 ft. level, below No. 7. The company has now in progress the sinking of the shaft below this for a new level, and in the upper series of the old workings, whenever the reef contributed occasional blotches of gold, it was invariably discovered to be near the rich shoot. Bearing in mind that the sea-level is 1,500 ft. below the crown of the hill, the future of this company below the present workings should be a good one. The company owns two portable engines, which will develop 30-horse power, aircompressor, air-winch, and Tangye pump, and also fifteen heads of stamps and two berdans. A parcel of 21 tons of quartz has been crushed, for a yield of 77 oz. 18 dwt. 2 gr., which realised £222 14s. Id. Thirty-five persons are employed. It is contemplated very shortly to amalgamate this property with the Boyal Oak. With this done, by the aid of the Tokatea plant for pumping, winding, and stamping, the Royal Oak can work their shaft dry, and give this famous reef a thorough good development in the virgin ground. Judging from the indications at the deepest point reached in the mine, and guided also by the experience of miners who developed this reef in the upper workings, it is very evident that this Tokatea main reef will yield large quantities of gold in the deeper workings. I may say both this company and the Royal Oak are giving the large trunk reef a thorough good development from the level to No. 3, and, although their efforts have not yet been successful, any day might discover a section of it to yield payable ores, in which case a reef of this magnitude would contribute a large reserve of ore immediately. Provision has been made for fuel to develop the property for more than twelve months in advance ; in the meantime water-power is being conserved for developing the mines on a permanent basis ; and the amalgamation is being urged forward, in order that the two companies may jointly contribute to work the two mines on a basis with water as a motive-power. The ultimate success of this property and the Royal Oak, by their combined efforts, judging from all the indications surrounding their mines, ought to again bring these mines into prominence as good payable properties. Triumph Mine (Area, 30 acres). —The levels opened last year were further extended. The adit-level, which is 320 ft. below the surface, is now in 552 ft., and when continued will intersect the No. 1 and No. 2 reefs. Driving and stoping have been done on those reefs, and a quantity of quartz is now ready for the battery. No great expedition was observed in the erection of this plant, and it is not yet completed ; therefore no quartz has been crushed. Forty men were employed. Golden Tokatea Mine (Area, 30 acres). —A considerable amount of driving was done on two small reefs, the Morgan reef, 1 ft. in thickness, and the Hibernian reef, 6 in. About 10 tons of lowgrade quartz has been taken from the Morgan reef, and a few pounds of picked stone showing gold, but no crushing has been done. Four men were employed. Harbour View (Area, 38 acres 3 roods 28 perches).—Very little work has been done, and no quartz crushed. Tokatea Consols, formerly New Tokatea Mine (Area, 30 acres). —This mine is owned by the Tokatea Consols Gold-mines (Limited). A considerable amount of development was carried out, levels being driven both from the east and west sides of the range. The reef at the east side is from 1 ft. to 4 ft. wide, and on the west side 6 in. to 1 ft. No quartz was crushed. Thirteen men were employed. East Hauraki Mine (Area, 29 acres 3 roods 32 perches).—The reefs on this ground are of small size, varying from 6 in. to 18 in. A low level has been driven 400 ft. to intersect the principal reefs. A connection was made by rising on Dunn's reef to the Comstock level. The quartz (about 60 tons) has not been crushed, and no gold has been obtained. Ten men were employed. Prospecting work has also been carried on in the Alexandra, Star of Tokatea, Coromandel Queen, East Tokatea, North, Pigmy, and Good Luck. Stirling Castle Claim. —This claim was worked by the owner, chiefly on small veins; 5 cwt. of quartz yielded 20 oz. of gold, value, £58. Napier Claim. —A crushing of 14 tons yielded 100 oz. 5 dwt.

Buffalo Mine (Area, 10 acres 1 rood). —This land comprises Montgomery's freehold, in the old Buffalo Settlement, and is situated on the range towards the head of Courthouse Creek. During the year 350 ft. were driven on the main reef, and a leader of gold-bearing quartz was found on the footwall side of the reef, but no quartz was crushed. Four men were employed. Good Enough (Area, 13 acres 3 roods). —About 300 ft. of driving has been done by the company, but no quartz was crushed. Two men were employed. Southern Star Mine. —The Southern Star Gold-mines (Limited), of London, are the owners. A considerable amount of prospecting work was done on the ground, of which Mr. Pearce, the mine-manager, gives the following account : — The Queen's reef is situated on the east end of the property. The reef dips west into the Southern Star Mine. The intermediate level on Queen's reef has been extended 61 ft. by two men, with very good prospects of gold. The country-rock here looks very promising. Driving on Queen's reef, south end, the low level has been extended by four men 168 ft., with very promising results. There will be over 100 ft. of backs to the surface to be stoped out. Driving on same reef, north end, the low level has been extended by four men 110 ft. We have met with fair results whilst driving. The main cross-cut from Queen's reef level will meet the intermediate level on the west side of the property, so that the mine will be able to be worked to greater advantage. This has been extended, by six men, 65 ft. The country-rock is very heavily mineralised. The Queen's No. 2 leader, south end, has been extended by four men 24 ft. in the last two weeks. The cross-cut for No. 3 leader, and also Pearce's No. 1 reef, has been extended by two men. A cross-cut has been driven 168 ft., driving on No. 3 leader 70 ft., and also a branch leader 50 ft. We passed through other leaders, most of them carrying low-grade ore. The No. 1 cross-cut for No. 1 reef (Pearce's) has been extended by four men 271 ft. The country-rock here is very heavy, and requires to be well timbered. The intermediate cross-cut for Pearce's No. 1 reef has been extended 199 ft. to the reef, by four men. Six men have driven along the line of reef 163 ft. In the cross-cut the countryrock was very short and tight. The intermediate level will meet the west cross-cut on the other side of the hill, so that the quartz can be conveyed by this route to the battery. The rise from intermediate level to surface has been extended, by four men, 49 ft. on the reef. The Southern Star general low level has been extended, by four men, 299 ft. Here the country - rock is very patchy, with hard bars, making progress slow. The total length driven on this level is 1,705 ft. Mining timbers have been cut out of the bush from trees growing on the mine property to the following extent: Cribbing timbers, 269; props, 392 ; slabs, 3,169; caps, 372 ; toms, 120; and sleepers, 298. Roads have been made on the mine to the extent of about 7 chains. A road to the machinery site of about 15 chains has been made, at a cost of £140. Two rooms have been erected on the mine, to be utilised as office and store-room. Two men are employed in the smithy, and the miners are under the supervision of a shift boss. There have been no accidents during the past year. Success Mine. —This mine has been energetically worked during the year. The battery of ten stamps was conveyed to the ground and erected in close proximity to the low-level adit. The following particulars with respect to this and the New Hauraki Gold Properties Mines have been supplied by Captain Hodge, the general manager:— Success Gold-mines (Limited). —The nominal capital is £50,000. The area owned by the company is 15 acres 2 roods 6 perches. The total expenditure since registration to the 31st December last is £10,809 14s. 2d. The number of persons employed has averaged forty-three. The greatest depth reached in this company's operations is 260 ft. below the surface. The developments have been conducted at various depths by means of seven levels. The reefs on the property vary in size from 6 in. to 3 ft. wide, and are composed of quartz, much associated with iron-pyrites. The reefs are intersected by floors of pyrites considerably oxidized. The company have done a considerable amount of development on the property, and have crushed 493 tons of quartz, which gave 209 oz. of melted bullion, realising £600 ss. lOd. In James's level, on the line of James's reef, running east and west, a cross-course was encountered having a dip westerly. The same cross-course was intersected in the deep level at a point near where the deep level intersected James's reef. All east of this cross-course the rock is composed of a compressed hard andesite from which large quantities of gold have been raised from the surface to about 30ft. below No. 3 Success level. On the western side of this cross-course referred to the rock is a moderately hard andesite. This also has produced a fair quantity of gold. The lines of development now proposed by the company is to sink below this level both in the decomposed and hard andesite rocks. The reef-formation maintains its uniform size in the deep level, and it is highly probable the reef will again be fed by similar floors of pyrites, as the rock so far as reached is very largely charged with it. If this is so (which there is no reason to doubt) there will be good chances of discovering fresh runs of the precious metal. The other developments of the company are conducted in following up the line where good runs of gold have been raised in the upper series or sections of the property. The company owns a ten-head battery, with four berdans, worked by a portable boiler of 20 nominal horse-power and a horizontal engine, 14 in. diameter cylinder, with a Pelton wheel to work the battery when water is available. A large chamber has been cut on the ground at the site for sinking a shaft, and machinery is on order to conduct sinking by compressed air. Judging from the well-defined walls of the reef going below the deep level and the character of rock, deeper working promises well to discover a permanent and payable reef in undisturbed ground below this level. Between this deep level and James's level the reef pinched by a horizontal hard-class rock, say diorite. It is satisfactory that below this to the level the reef gradually has increased in size, is assuming its uniform formation, and the walls are getting well-defined ; to say the least, the development below this level is a very important matter for the future of the company. New Hauraki Gold Properties (Limited). —This property comprises an area of 182 acres 2 roods 28 perches, 14-J- acres of which is a licensed holding, the other portion being freehold
43
C—3
property. The deepest point worked on this property is 274 ft. below the surface. Operations have been conducted with seven levels at various depths and on different reefs, each varying in size from 6 in. to 18 ft. The average number of persons employed on this property is thirty-two. In the 14-J-acre section of this property a prospecting level is being driven in virgin ground. The total distance driven here is now 314 ft. For some time past the rock driven through in this level has been a hard diorite. It is hoped to be through this rock shortly, judging from the more moderate andesite rock outcropping on the surface in advance of this level. From the South Tokatea tunnel the company is developing a reef northerly on the supposed No. 1 Success reef, and, inasmuch as this drivage is towards the gold-bearing belt, there is ground for expecting to discover good runs of gold characteristic to the Success reefs at this depth. Northerly from this development a new prospecting cross-cut is also being developed, in the hopes of intersecting the same No. 1 Success reef. The rock so far as driven in (24 ft.) is a true decomposed andesite rock, and, inasmuch as loose colours of gold can be raised around the surface in this section of the ground, there is reason to expect cutting a productive reef. A new reef is being developed in the freehold property, in which occasional colours of gold are being met, and, speaking from the character of the reef so far as developed, it is hoped by the deepest level just being initiated on this reef to discover a payable reef. The company is also developing an east and west reef, varying in size from 3 ft. to 17 ft. wide, known as No. 1, No. 2, and No. 3 level cross-cuts. In the No. 1 and No. 2 levels large bodies of ore have been driven on, but so far of too low grade to pay for working. By following up the development of this reef, however, there is no reason to suppose but what payable sections of it will be discovered, as its development is practically all in virgin ground. The company is also working a hand rock-drill in the lower sections of its property, with a view to test the rock at different points. The area of this property and the various number of reefs traversing through it, and considering the prospects of gold traced in various parts of the property and surface prospecting, with further developments should discover some sections payable. The company has expended £7,727 14s. sd. in the colony since registration to the 31st December last. Waikoromiko District. In the under-mentioned mines a large amount of prospecting work was done, but no yield of gold has been reported. Machinery for crushing is not yet erected in the neighbourhood, but it is expected that a mill will be shortly erected by the Hauraki Associated Reefs Company, which will give a chance for public crushing from the mines—Rialto, Fabulous, Cuirassier, Golden Butterfly, Plunger, Jocelyn, Tandem, Trilby, Tokatea, Hinemoa, and City of Chester. Whangapoua Mine (Area, 100 acres). —This mine is situated at Waitekauri Block, Whangapoua, and joins the Waikoromiko claims. The reef is from 2 in. to 2 ft. 6 in. in width, and produces specimens. As the country is at present inaccessible for carting quartz, 4J tons only were sent to the mill, but this, with 1501b. of specimens, produced 720 oz. of gold ; value, £2,180 7s. Two men were employed. Forest Queen Mine. —A small crushing of 19 cwt. of quartz yielded Boz. 10 dwt. of gold ; value, £25 10s. Five men were employed. Four-in-Hand Mine (Area, 30 acres). —This mine is situated in the Waikoromiko district. A considerable amount of work was done during the year. The reef, which is from 4 ft. to 6 ft. in width, was driven on for 200 ft., and a rise 60 ft. put through to the surface. As this mine is far removed from a battery the bulk of the quartz was not crushed, but 400 lb. of specimens were treated, for a yield of gold value £900. Seven men were employed. Kapanga District. Kapanga Mine (Area, 99 acres 3 roods 27 perches).—This mine, the oldest held by an English company in the Auckland District, is still being vigorously worked. The return of gold for the year was 531 oz., obtained from 843 tons of quartz. The workings in the mine are of very great extent, and carried on from two shafts, the Kapanga shaft, 1,007 ft. in depth, and the Corby shaft, 185 ft. Gold occurs in many places, although no extent of rich specimen stone has been obtained. There is, however, always, when working on reefs in this mine, a chance of unearthing one of those patches of specimens similar to the rich finds obtained in the past. This company deserves success on account of the large amount of capital it has invested, for the untiring perseverance displayed in opening the mine at such a depth, and also for carrying on operations without having obtained adequate returns of gold for several years past. It is also intended to use the diamond drill in boring, with the view of sinking the main shaft to a greater depth should indications prove satisfactory. Mr. W. H. Argall, general manager, and Mr. H. Battens, mine-manager, give the following account of the mine :— Tutwork measurements (exclusive of stopes) : Engine-shaft has been sunk 207 ft.; drives on reefs and branches, 540 ft.; risings, 569 ft.; levels cleared and retimbered, 320 ft. Corby section : Shaft retimbered, 80 ft. ; shaft sunk, 65ft. ; drives cleared and repaired, 200 ft. ; drives on reefs and branches, 190 ft. Stopes: In this connection 740 tons of quartz has been treated, but a large proportion of it was of very low grade. During the year Larnach's engine-shaft has been sunk 207 ft., its size being lift, by Bft. within timbers. For the entire distance it has been securely timbered with 10 in. by 8 in. timber, and all the necessary centre-pieces, cage- and ladder-roads, have also been constructed, with the requisite sollars and bye-launders. We have also fixed alO in. bucket-lift, and al2 in. plunger-pole at the 600 ft. level, with a 13 in. rising main. We found it advisable to do this in order to counteract the weight of main rods, and it will also enable us to sink as low as the engine's capabilities will allow without incurring any further expense. The shaft having been sunk to the required depth, preparations were made at once for opening out at the 1000 ft. level. A chamber 24ft. by 10ft. by 8 ft. within timber has been cut, and the ground 7—C. 3.

properly secured; also the second cage-road put in. The shafting and poppet-legs, cage- and ladder-roads, are now completed ; also the necessary pitwork. From the top of the poppet-legs to the bottom of the shaft the distance measures 1,075 ft. At this level we started a cross-cut southeast, and during the first 18 ft. we intersected a small reef 6 in. wide, composed of solid quartz heavily charged with mineral and arsenic, slightly deviating from the direction of the cross-cut; in fact, the deviation was so little that we continued on the line of reef, which has now advanced 125 ft. This is, in all probability, a " dropper" from the reef cut in the shaft at the 940 ft. By continuing this drive we shall test the character of the reef, and ere long intersect the main portion of the reef. During the progress of this drive the reef has varied considerably, sometimes opening out to 14in., but the average width would not be more than 6in. It has carried good quartz for the whole distance, and is highly charged with arsenical pyrites. At about 96 ft. from the shaft we intersected another reef, bearing north-east and south-west, about 12 in. thick. This has been driven on for a distance of 17 ft. It is encased in a splendid class of sandstone, and is of such a character as should produce gold in quantity, though at present the ore obtained is not payable. At the same level we started a cross-cut south-west, which has been carried for 290 ft. A small leader about 5 in. wide was cut in the first 18 ft., which, though fine in quality and highly mineralised, showed no gold. At a further distance of 170 ft. two small veins were cut, both of which, though small, were excellent in character. We have here a much larger body of water to contend with than in the upper levels. Of course, the main object in advancing this cross-cut is to intersect our two old and tried reefs —Kapanga and Scotty. At the 940 ft. level, after cutting a chamber, we drove in an eastern direction on the line of reef, which has been continued both east and west for a distance of 89 ft. and 99 ft, respectively. The reef has varied in width from 2 ft. to 20in., and in both directions has carried small deposits of gold for the whole distance, and occasionally very rich pieces have been taken out. A bar or band of iron-pyrites, 2 ft. thick, has very much interfered with the extraction of the gold. At the junction of the bar with the reef gold was made. In relation to this mineral band, we were prompted to forward a sample to the local assayer, with the following results: Nos. 1 and 2, from the west drive, assayed—No. 1, traces of gold ; No. 2, 6 oz. 8 dwt. 13 gr. of gold and 1 oz. 17 dwt. 20 gr. of silver; value per ton, £25 17s. 9d. Nos. 3 and 4, from the east drive, assayed—No. 3, traces of gold; No. 4, 1 oz. 2 dwt. 16 gr. of gold and 10 dwt. 2 gr. of silver; value per ton, £4 lis. Bd. This band has accompanied the reef for the whole distance driven, and is 12 in. to 18 in. thick, of almost solid mineral. In the rise mentioned below another similar band has been met with, 8 in. thick, and has run with the reef right up to the rise. This band is a medium for the gold, and wherever it junctions with a reef rich deposits are found. We have put up a rise on the reef in the east drive for a distance of 42 ft., which is looking well, and showing strong blotches of gold. It was imperative that this rise should be put up to the 900 ft., in order to secure ventilation ; besides which, by so doing, a large block for stoping was at our command. A certain amount of stoping has been done. The reef is 20 in. thick, carrying a little gold, but it is heavily charged with mineral. Having completed the rise, we continued the east drive, but a slide coming in disordered the reef, and for a time we lost it; but by further driving we recovered it in an improved condition, but still accompanied by the band of iron-pyrites, which we consider an excellent indication. In the 900 ft. level a cross-cut east has been driven 42 ft. About 20 ft. in we cut a small vein, 4 in. thick, carrying a good class of quartz, and in 20 ft. more we intersected a 4 in. leader showing payable ore. This leader we have driven on for 42 ft.; it soon increased to6in., and subsequently to 10 in., gold having been seen for the whole distance ; and there is every indication to warrant favourable expectations. During this driving we intersected a reef running at right angles to the former one, which, though presenting a fine body of stone, did not betray payable ore. At this level we have initiated a cross-cut north-east, with the intention of picking up the reef cut through 16 ft. below the level, and which, where intersected, was found to be gold-bearing, a few specimens being taken out at the time. This cross-cut has advanced 36 ft. There is every encouragement to hasten and develop work at this level—in fact, from this point to the 1,000 ft. level every foot of ground should be prospected, as the country is one network of reefs, leaders, and veins, mostly gold-bearing, though in small quantities. The rise at the 800 ft. level has been stopped, and we have started to cross-cut west from the 700 ft. level to intersect this rise. We shall thereby obtain additional ventilation, and from the point of intersection continue the rise through to the 600 ft. This cross-cut has been advanced 110 ft. In the first 15 ft. we intersected a leader, 8 in. thick, carrying a body of highly-mineralised quartz. The next few feet of driving led us into the dyke, which we encountered in the shaft below the 600 ft. This somewhat retarded progress, but in the following 15 ft. we got clear, and cut into a composition of pug and mullock, which gave place to a more congenial class of country, with a good stream of water running from the face—probably owing to the nearness of a reef. Driving north above the 500 ft. level on Kapanga reef has been extended a further distance of 132 ft. The reef has averaged 8 in., composed of favourable quartz and pug, while the country - rock has considerably improved, and is carrying streaks of jasper, which is considered a good indication. This drive will lead us under the runs of gold to the north of the present face, and we are endeavouring to hasten this work as much as possible. The stope at the back of the drive has produced ore of low grade. The 420 ft. level (main drive south on Kapanga) has been advanced 115 ft. and repaired for 87 ft. The reef has varied during the drivage from 6 in. to 18 in. and at times has been much disturbed, owing, no doubt, to the broken and mixed character of the country-rock. An increased body of water has been encountered, and, from indications at the 300 ft. level, we are of opinion that this increase is coining from that level. The ore from the reef has been of low grade ; but with a better class of country coming in, and a more uniform reef, we are anticipating an improvement in the quality of the ore. The rising above 420 ft., on Scotty's reef, has been holed through to the intermediate proper. The reef has been from 8 in. to 18 in.
45
0.—3
thick, and the ore from the reef, as well as that from the stopes north of the rise, has been of rather low grade; but recently the reef has widened out in the stopes, and is now 4 ft. thick, carrying a good hanging-wall, and altogether presenting a much more favourable appearance. The rising above intermediate on Scotty's hanging-wall has been extended 102 ft., for a greater portion of which distance the country has been first class. The reef, 7 in. thick, opening out recently to 2 ft., has carried gold for a considerable distance. We have commenced stoping north, and have obtained fair crushing-dirt. In the 300 ft. level the winze which was started and continued for about 40 ft. with such promise is at present suspended, pending the completion of repairs to main drive at this level. In the Corby section the engine-shaft has been sunk a further distance of 39 ft., making a total depth of 185 ft. At present this work is stopped, so that we may push on the cross-cut at the bottom of the shaft to intersect the Kapanga reef. The No. 1 drive on reef has been advanced 91 ft. The width of the reef has averaged 11 in., with good walls, and is really a fine body of quartz. We fully intended to continue this drive, but a strong volume of water issuing from the face compelled us to suspend the work. We shall resume as soon as water will allow to get under Cotter's winze, as gold has been carried along there. The rise above this drive has advanced 40 ft., where we intersected a reef 12 in. wide, running about north and south (a superior body of stone, which we have driven on for a distance of 79 ft., and it has maintained its character throughout), the indications of which are favourable in every way for producing gold. A cross-cut has been started in the No. 1 level, and has advanced 51 ft. The object of this is to intersect Scotty's below the Golden Point Tunnel, where rich gold was found in former years, but in the absence of machinery to cope with the water the workings were abandoned. We are expecting to strike the reef in about 40 ft. The drive south of Cotter's winze, on line of reef, is still being carried on, and the reef, though small, continues to show gold, which at times is rich. We feel sure the ground all round the Corby section would pay well to be thoroughly worked and developed, but we would not depend so much on the shallow or surface levels as we would in depth, for while in the former you here and there get small pieces of flaky gold, in the latter you are more likely to get it in greater abundance in the quartz, and more continuous. In drawing this report to a close, we would like to remark that, in connection with the boring operations about to be started, we have been comparing notes in relation to the last operation, and are both of opinion that, by commencing with a large bore— say, 7 in.—we are likely to make better progress than before, as we can more easily reduce to 2 in., if necessary, than we could increase from 4 in. to 7 in. Permit us further to say that we are in favour of further testing, not because we are discouraged or disappointed with the present results of the lower levels, but rather because these very results are indicative to us of a much better class of country for the production of rich metal. Scotty's Mine.— -This mine has been continuously worked during the year, and extensive developments carried out. Captain Hodge, the general manager of the company, gives the following report on the mine and workings : — This company's property is adjacent to the famous Kapanga Mine : the reefs traversing the same are the Scotty's and the Kapanga, as well as parallel ones. The company have conducted considerable developments since their initiation. A permanent shaft has been sunk to a depth of 325 ft. The principal workings now being conducted are at the 355 ft., on the line of the reef known as Breuer's reef, and the sinking of a winze below that level. Nearly five hundred pounds' worth of gold was broken out from the 355 ft. level on the 26th January last by a few shifts working. Seeing this, it is only reasonable to suppose that by deepening the shaft and following this line of reef considerable quantities would be won. Another very important development in relation to this property is the discovery of a reef near the battery. This is practically one of the well-known New Hero reefs, in the adjacent property. The Scotty's company is now engaged sinking a prospecting winze below the creek-level on this reef. The reef is running approximately north-westerly, and its dip is easterly. In the reef, which averaged lft. wide, we have seen strong dabs of gold. The company is now recommended to sink a trial shaft on the site of this winze, and this development will be one of great interest, the quartz being of the same character as that found in the Hauraki lode and in Scotty's ground, never having before been worked except at one point, say, a few feet below the clay or surface. The area of the company's property is 38 acres 1 rood 2 perches. The total expenditure locally up to the 31st December last has been £12,506 Is. Bd. The total quantity of quartz crushed since its initiation up to date has been 122 tons, which gave 256 oz. 17 dwt., realising £749 17s. A good winding-engine is erected on the property, poppet-heads, two patent cages, and a plunger-lift for pumping to the 300 ft. The company have nine heads of stamps and three berdans, worked by an overshot water-wheel. The average number of persons employed is thirty-six. This company, having in view the development of the mine from the main shaft in depth, as also the sinking of a prospecting shaft near the battery, is now ordering two 25 nominal horse-power Cornish boilers, and a pumping-engine with air-com-pressors and plant. The future of the company, when the developments mentioned have been carried out, should be a profitable one. Britannia Mine (Area, 40 acres). —This mine is owned by the Britannia (Hauraki) Goldmining Company (Limited), of London. During the year the shaft has been sunk a further depth of 100 ft., and is now 220 ft. from level of the creek. A chamber was opened at this level, and a cross-cut driven 140 ft. No reef has yet been cut in the shaft, but the Flying Cloud and Junction reefs were formerly worked in this ground. The present machinery is a 10-horse-power steamwinch for winding and also for baling water, and a Tangye vertical boiler. From four to sixteen men were employed. The manager has recommended the purchase of new machinery, to consist of a pair of winding-engines about 35-horse power, and horizontal pumping-engine of 80-horse power, capable of working a 12 in. set of Cornish pumps.

Blagrove's Freehold (Area, 128 acres). —The main shaft has been sunk a further distance of 55 ft., and is now 255 ft. in depth. A chamber was excavated at the 200 ft. level, and crosscutting done. Several reefs were cut. The engine is found to be insufficient for pumping and winding, and a second 65-horse-power steam-engine is being erected to do the pumping, the other engine to do winding only. Thirty men were employed. Prospecting work has been carried on in the Great Kapanga, Conquering Hero, Coromandel, Dolcoath, New Hero, and Hauraki Gem. Kauri Block. Great activity has been displayed in carrying on mining operations in this portion of the goldfield. Upwards of sixteen engine-shafts are used. Captain Hodge has furnished the following reports on those mines in this district over which he has full control: — Hauraki Main Lodes Company (Limited). —This company started work in November last under very favourable auspices, being in the same auriferous zone as, and adjacent to, the Hauraki and Golden Pah Mines, and embracing several of the various reefs that traverse those properties. The property consists of two claims—viz., the Albion Special Claim, of 20 acres; and the Albion Extended, 78 acres 3 roods 37 perches: total, 98 acres 3 roods 37 perches—and is situated on the foreshore eastward from the Coromandel Harbour. An engine-shaft has been sunk to a depth of 145 ft., the size being 11 ft. by 7 ft. within timber, and all timbered in a substantial manner with frame set timber 8 in. by 8 in., and cased 9 in. by 2 in. The rock penetrated in sinking this far for the most part has been favourable decomposed andesite rock, which contributes in this locality to the production of very rich gold-bearing reefs ; in fact, the indications as far as strata is concerned augur well for a good property after thoroughly developing the reefs. It is proposed at the 150 ft. to open a chamber and resume sinking immediately for the 200 ft. level, and at this stage to proceed with the development of two levels—the 150 ft. and the 200 ft. The present shaft is being sunk by a temporary plant —a small portable boiler, Tangye pump, and steam-winch. A very substantial poppet-head is now in course of being built, for which concrete loadings are completed around the shaft to receive the same. In the meantime a pumping-engine, with a pair of 10 in. cylinder winding-engines, with adequate foundations and buildings, are about to be erected for the thorough development of the property. The company has crushed 4 tons of quartz and 241b. of concentrated black sand, which gave a result of 4oz. 9 dwt. of retorted gold. This was raised in excavating for the engine-shaft on the bed-rock, or between the bed-rock and the machine mud. The average number of persons employed on this property is thirty. Speaking of this property, its position and facilities for working with a permanent plant erected ought to prove, if indications go for anything, that it is a very valuable one. Hauraki Gold-mining Company (Limited). —This property contains an area of 28 acres 3 roods 11 perches. The developments are conducted with two shafts, the main shaft being 315 ft. and the lona shaft 170 ft. From the main shaft there are five main levels—viz., the adit-level, 100 ft., 160 ft., 220 ft., and 300 ft. The company own a battery with fifteen heads of stamps and nine berdans, driven by steam-power, the bullion being extracted by amalgamation. The quartz crushed for the year ending 31st March has been 4,437 tons, yielding 24,656 oz. 7 dwt. of bullion ; while the average number of persons employed during the year has been 180. There are twelve reefs or veins traversing the property. The principal ones developed have been—No. 2, bearing north-west, with an underlay north-east; average width, 10 in. : No. 3, bearing north and south, underlay east; width, Sin. : No. 6, bearing north and south, underlay west; width, 3 in.: Cross reef No. 1, bearing north and south, underlay west; average width, 3 in. : Cross reef No. 2, running north and south, underlay west; average width, 3 in. : Castle Rock reef, bearing east and west, dip north; average width, 12in. : lona reef, bearing north and south, dip east; average width, 10in. : New Year's reef, bearing north and south, dip north-east; average width, 12 in. The principal reef and the richest has been the No. 2, generally known as " Legg's reef." The Cross reef No. 1 and the lona and New Year's reefs have also contributed largely to the company's returns. The mines are being worked very profitably at the present moment, are kept continually drained to the bottom, and are being thoroughly developed, and everything kept in regular order. For the further extensive development of the property in depth foundations are being excavated for new pumping-engines, their capacity being two 18 in. diameter cylinders, high pressure, and estimated to sink the mine 1,500 ft. with a 12 in. diameter lift of pumps. The Castle Rock reef is estimated at a depth of near the 600 ft. to be in the same character rock which has produced the greatest portion of gold in the various reefs, and may be looked upon as a very important reef for development, outside of the various other reefs, which, of course, will be followed up and developed as the mine is being sunk. There is every probability of the mine continuing to pay good profits. The Union Beach section of the company's property embraces a portion of the Coromandel Harbour. On this property the shaft is sunk 180 ft. This is now being drained by the Hauraki Company. Foundations are nearly completed for the erection of 10 in. cylinder winding-engines. These engines, with two 25 nominal horse-power boilers, are being landed in Auckland. The company propose to develop this property from the bottom of old workings on the line of reefs below the 180 ft., where rich gold was raised in the early history of the working of this ground by sinking shafts. Motive-power for sinking these shafts is being provided by an air-compressor engine, air-winch, and air Tangye pump, conducted by pipes and air-receivers from the site of the shaft and the surface to the proposed sites of the shafts underground. The result of these workings, if successful (and there is every reason to believe they will be), will then henceforth be conducted permanently by raising a new shaft to the surface, and henceforth adopting a permanent basis for following continued workings in depth. I attribute the success of working the Hauraki Mine and regularity of the returns to the simultaneous working of the various reefs at different levels. Since the company's initiation there was driven nearly
47
0.—3
4,000 ft. of cross-cutting, while at the same time the drivages on the lines of reefs have been about the same distance—4,ooo ft. The dividends paid by the company to the 27th September, 1896, have been £112,000. The expenditure in the colony for the year ending the 31st December last was £22,987 17s. 3d., while the total expenditure since the company's registration to that date was £42,714 7s. lid. Golden Pah (Hauraki), Limited. —This company has a nominal capital of £62,500. The total expenditure since registration to the 31st December last has been £1,087 locally. The area of the property is 18 acres 3 roods. A permanent shaft is in course of being sunk, now down 100 ft. from the surface. An adit-level from the road is constructed 400 ft. in length. The company has also a second adit-level 100 ft. in length. Two tons of quartz has been raised from the Jewellers' leader, which yielded 3oz. 19 dwt. bullion. The average number of men employed by the company is thirty-four. A very substantial poppet-head has been erected at the Pah shaft. The shaft itself has been very securely timbered with frame sets from the brace to the bottom. The size of the shaft is 7 ft. by 11 ft. within timber. The excavation for machinery is in a forward state for a permanent plant, both for pumping and winding purposes. Smith's and carpenter's workshops, mine office, and material-house are completed. A very substantial engine-pool or reservoir has been constructed to contain water to supply the boilers for the permanent plant. The machinery to arrive shortly consists of one 22 in. by 48 in. horizontal high-pressure pumping-engine, with balance-bobs, bridles, caps, bolts, shaftings, crank, main gudgeon, plummer-blocks, caps, brasses, and all complete ; one pair of 10 in. by 15 in. winding-engines, with slot-link, reversing gear, drums for winding, foot-brakes, clutch-gear, and all their equipments complete ; and two steel Cornish boilers, each 22 ft. 6 in. long by 5 ft. 6 in. diameter, with fittings and. all complete, supplied with donkey-pump, 4 in. steam and W\ in. ram for feeding boilers, exhaust-pipes, horizontal condenser, and all intermediate gear complete. A temporary plant is being constructed to carry on sinking the main shaft pending the arrival and erection of the permanent plant. This company proposes to cross-cut from the 180 ft. level cross-cut from the Union Beach shaft to come under the Golden Pah shaft ; in so doing reefs will be cut through, and 100 ft. vertical will be available below the 80 ft. level from the Pah shaft, on the Golden Pah leader, the Jewellers' leader, and other leaders. The result of working these leaders when fully laid open is expected to yield fair quantities of gold. At present nearly the whole of the miners are engaged in preparing for the reception of the new plant. From a mining point of view, there is every reason to suppose this property will be a good gold-producer. Kathleen Gold-mine (Limited). —This company adjoins the Hauraki to the east, on the sections where the Hauraki Company's principal workings are conducted. The area of land held consists of 56 acres and 2 perches under Land Transfer title, freehold. The situation of the property is unique, as it embraces the junction of two well-known auriferous belts, in which are traversing in all directions a considerable number of reefs. The number of persons employed by this company averages forty-two. An engine-shaft has been sunk in a site to command the working of all the reefs therefrom to the best advantage. The shaft is now down below the surface 240 ft., all timbered with frame sets 11 in. by 7 in. At a depth of 200 ft. two cross-cuts have been driven north and south. The cross-cut southerly has been extended a distance of 80 ft. In this cross-cut a reef was intersected, known as Carlyon's reef, and has been opened on north 27 ft. and south-west 28 ft., the average size of the reef being 9 in. Visible gold has been met with in this drivage, and, from its appearance, on being fully developed throughout the property, should yield payable gold. The 200 ft. level cross-cut north has been extended from the shaft 100 ft. The andesite rock passed through in this drivage has been very largely charged with iron-pyrites, and is in every respect characteristic to the rock that produced the gold in the reefs found therein in the famous Hauraki Mine. In this cross-cut we intersected a large reef, at its intersection 6 ft. wide, carrying two welldefined walls, running nearly east and west and dipping north. We have seen colours of gold in the quartz occasionally. The quartz formation in this reef is almost identical in character to the Hauraki main reef, carrying considerable quantities of iron-pyrites, and very heavily charged with water. We have opened on the line of this reef north-easterly and south-westerly 40 ft., the average size of the reef for this length being about 4 ft. This continuation of the cross-cut north is going in the direction of the Hauraki North and Golconda series of reefs, and, speaking from the character of the rocks being penetrated and the large volume of water we have to contend with, it points to a good future for the company in this direction. The cross-cut southerly will also cut a large number of reefs, which on being cut and opened up on their line will make junctions or intersections with other reefs that cross them ; so that, putting the prospects of the company together, there is a great probability of a successful mine before the company. The pumping-engine is one of Tangye's combined coupled horizontal steam-engines, having high-pressure cylinder, diameter 16 in.; low-pres-sure cylinder,24in.; stroke,3oin.; fly-wheel, 13 ft. ; width of face, 22in.; the engines being coupled together. The whole is complete, and erected upon concrete foundations. The pumping-engines were set to work on the 13th February last. The winding-engines consist of one of Tangye's couple-geared winding-engines, with two drums, having steam cylinders 10 in. diameter by 22 in. stroke, with eno-ine-bed, crank-shaft, cross-head guides, and all complete, built upon concrete foundations, and housed with buildings. These were set to work on the 24th December last. To work the engines two Tangye steam Cornish boilers, each 25 nominal horse-power, are built in and connected with the engines complete. Poppet-heads have been erected over the shaft, with patent cages drawn by Bulivant's patent steel-wire ropes. The cages work by patent safety detaching-hooks, all complete. The pitwork consists of one 13 in. plunger-lift, with 14 in. pumps from the 200 ft. level to surface, the main rods being 10 in. square. Everything is in working-order, and doing a considerable amount of pumping. Carpenter's and smith's workshops, magazine for explosives, changing-house for the miners, company's office, and a road from the main road to the shaft are all completed and in working-order. Shafts have been sunk 336 ft. —viz., main shaft (Hartridge's), 240 ft.; puddling

shafts, 96 ft. Levels have been driven 100 ft. on the line of reefs. Cross-cuts have been driven 264 ft. The cost to the company for sawn and mining timber for the above developments is very nearly £1,000. The total expenditure of this company since registration to the 31st December last was £9,125, the nominal capital being £75,000. As far as the future of this company is concerned, any blast on the line of reefs (and the same remark will apply to the cross-cuts) might discover a rich property. Bunker's Hill Mine (Area, 3 acres and 12 perches).—This mine adjoins the Hauraki Mine to the northward. The shaft was sunk to a depth of 285 ft., and No. 2 level opened at 270 ft. The cross-cut at this level was driven 364 ft., and two reefs were intersected, as well as several leaders. No. 1 reef averages 18 in. in width—a compact body of quartz, in which dabs of gold are seen. 94 ft. of driving was done on this reef. No. 2 reef is of a puggy character, 1 ft. in width, on which no work is done. No. 1 leader is 2 in. in thickness, and was driven on 30 ft. A considerable quantity of quartz has been raised from the drives and in stoping on No. 1 reef, but no crushing was done during the year. Seventeen men were employed. Hauraki No. 2 (Area, 6 acres). —A shaft has been sunk 208 ft., and a level opened at 200 ft. This was in hard rock for 90 ft., and no reef is cut as yet, The winding is done by a steam-winch, and a Tangye pump raises about 1,300 gallons of water per hour. Ten men were employed. New Golconda Mine (Area, 5 acres). —The shaft was continued to a depth of 140 ft., and a chamber formed at 130 ft. Driving has been done in cross-cuts 266 ft. in a north-east direction, and 75 ft. to the north-west. Several leaders, from a few inches to 15in. in thickness, were cut and about 200 ft. of driving done on these reefs, and, although some of the quartz looks promising, no gold has been seen. Winding is done by a steam-winch, and a Tangye pump raises 3,000 gallons per hour. Twelve men were employed. Zealandia Mine (Area, 24 acres). —The shaft has been sunk to a depth of 157 ft. The manager, Mr. Bichard Harrison, gives the following description of the workings : — Since taking charge of the Zealandia on the 15th June, 1896, I have sunk the shaft from 90 ft. to 157 ft. The shaft is lift. 6 in. by 4 ft. 6 in. in the clear. At 150 ft. a chamber lift. 6 in. by Bft. and 10 ft. high was cut out. We have driven a main drive from the chamber 234 ft. going south-east and 200 ft. going north-east. We have cut several leaders in these drives from 2 in. to 3 ft. thick, and have driven upon some of them. No. 1 leader is a fine-looking body of ore about 9 in. through. We have driven 30 ft. upon this leader, going north-east (towards the Hauraki). The country-rock is of a good description for gold, being a nice-looking bluish sandstone. No. 2 leader is a splendid-looking body of stone 3 ft. thick. We have driven 40 ft. upon it, also going north-east. The country is like No. 1 leader. We have driven 9 ft. upon this leader, going southwest. We have also driven 16 ft. upon another leader, but so far we have not been fortunate enough to get gold. Welcome Find Mine (Area, 8 acres 1 rood 8 perches).—Work in this mine has been continuously carried on during the year. The main shaft was sunk a further 60 ft., and is now 190 ft. in depth, the No. 2 level being opened at 170 ft. from the surface. There are four reefs intersected, varying from 2 in. to 6 ft. in width, the quartz being of a hard and white crystallized character. About 750 ft. of driving, mostly cross-cutting, has been done, 120 fathoms of reef stoped out, and 56 ft. in rising and sinking on reef. Of general quartz, 54 tons was crushed, for a yield of 227 oz. 10 dwt. of gold, and a parcel of 2701b. of specimens yielded 304 oz. ; being a total of 531 oz. 10 dwt. of gold ; value, £2 16s. 6d. per ounce. The company having no battery, the quartz had to be crushed at the Thames. Fifteen men were employed. Hauraki North Mine (Area, 142 acres).--The shaft was sunk 50 ft., and is now 150 ft. in depth. 205 ft. of driving was done, and a winze sunk 40 ft. on the reef. The reef is nearly vertical, and has a width of 2 ft. The machinery used is one 8-horse-power Tangye tubular boiler and a steamwinch for winding, and a No. 4 Tangye is in use for pumping. The crushing machinery consists of a Bobinson ore-crusher (equal to three stamps of 7 cwt. each), one stonebreaker, one Bobinson's concentrator, and two berdans. The quantity of quartz crushed was 120 tons, which yielded 291 oz. of gold ; value, £3 per ounce. Sixteen wages-men were employed. Hauraki South Mine (Area, 17 acres 1 rood 25 perches).—This mine is now owned by the Hauraki South Gold-mining Company (Limited), of London. Very little work was done during the year, but towards the end of March a commencement was made in excavating preparatory to sinking a shaft, in pursuance of the new scheme of development. The shaft is to be 13 ft. 8 in. by 6 ft. clear of timber, the frames 8 in. by 8 in., with 9 in. by 3 in. sheathing, and will be divided into three compartments. A temporary winding plant consisting of a 10-horse-power boiler with winch is used. It is intended to sink 200 ft. before opening out. Wynyardton Mine (Area, 8 acres). —The shaft has been sunk to a depth of 90 ft. No. 1 level was opened at 85 ft., and two cross-cuts put in and a small leader of quartz cut. Six men were employed. Kathleen Crown (Limited) Mine. —Captain Argall has furnished the following account of the work done : The area of this English-owned mine is 95 acres, and is joined on the north by Blagrove's Freehold and on the south by the Kathleen. During the year a temporary steam plant was erected, with which sinking operations were carried on ; but recently a pumpingengine has arrived from England, and is now erected ; also the usual buildings—viz., blacksmith' s and carpenter's workshops and offices. Considerable anxiety, and no little difficulty, was experienced in obtaining good foundations for the poppet-legs to rest upon; the ground being so unreliable, it was found absolutely necessary to lay down solid concrete beds. The legs are fine sticks, 60 ft. high. The shaft has been sunk 185 ft. and securely timbered, cage-roads and ladder-ways put in; also new pit-work. A new and powerful winding-engine is en route from England, and when erected the mine will be fully equipped. During the period of the present ownership a considerable amount of prospecting has been done, with the result that several reefs
49
C—3
have been discovered, showing gold in the dish. It is the intention of the manager to sink the shaft to the depth of 200 ft., and then open out on the reefs found on the surface and in the several drives, and it is anticipated that rich discoveries will be made during the coming year. Preece's Point Mine (Area, 200 acres). —This mine is owned by the Preece's Point Proprietary (Hauraki), Limited, an English company. During the year the engine-shaft has been sunk 215 ft.; three chambers have been cut, one at each of the levels —viz., 70 ft., 150 ft., and 200 ft. ; 550 ft. of cross-cutting has been accomplished; besides 200 ft. driven on line of reef. Old levels have been cleared and retimbered for 650 ft. The following machinery has been erected: A pumping-engine capable of pumping from 1,000 ft., and a winding-engine equal to winding 600 ft. per minute from a depth of 1,500 ft. New poppet-heads, 60ft. high, have been erected, with all the latest appliances; also patent safety-cages, with detaching-hook for overwinding. Fifty men were employed. The Golden Shore Foreshore Claim, of 100 acres, and the Golden Shore Extended have been taken up on both sides of Preece's Point. Gadman's Gully, Karaka, and Pukemaukuku District. A considerable amount of prospecting was done on Aitkin's Freehold, and 50 tons of quartz was crushed, for 33 oz. 15 dwt. of gold, but, in consequence of litigation in connection with the title, work was suspended. Eight men were employed. Katie Mine (Area, 89 acres). —Prospecting work was carried on during the year, but no quartz was crushed. The Empress ground has also been occasionally worked, but no quartz has been crushed. The Pegasus, Gordon, Standard, Poneke No. 2, Exchequer, Alameda, All Nations, Flower of the Range, and Coromandel Queen Claims have been prospected. In the following mines in the Tiki district a large amount of prospecting work was carried on, and numerous leaders cut, but so far no returns of gold have been made for the year : Matawai, Pride of Hauraki, Gem of Hauraki, Specimen Hill, Gem of the Tiki, Nestor, Pukewhau, Alert, Native Chief, and Coromandel Mint. Coromandel Freehold Proprietary Company (Area, 536 acres). —The land owned by the company is that block in the Tiki district known as Mrs. Mcintosh's. A rush took place to this part in 1879, and arrangements were made between the miners and the owners so that the ground could be worked, the land at that time not being included in the goldfield. A number of claims were taken up and a battery erected, but after a few years the district was abandoned, although considerable quantities of gold were obtained from Blackmore's and other claims. The present owners have had a staff of men engaged in opening up old levels and in prospecting work generally, and, as numerous gold-bearing reefs and leaders are known to exist, there is a hope that in a short time payable quartz may be found. Ten men were employed. Castle Bock District. Progress Castle Bock (Area, 60 acres). —This mine has not been continuously worked during the year. The old levels were secured and a winze sunk on the reef, from which a small block was stoped out. A parcel of 1 ton 5 cwt. of quartz was crushed at the Thames School of Mines, for a yield of 35 oz. of gold. Five men were employed. The Vaughan, Wakiti, Gem of Hauraki, Golden Gem, Mahinapua, and Wairakei Claims have also been taken up. Manaia District. Golden Hill Extended Mine (Area, 36 acres). —Operations have not been carried on in a very extensive manner. A small battery of two stamps, capable of crushing 2 tons per day, was erected, and 17 tons of quartz crushed, for 3oz. 3dwt. of gold; value, £11 2s. 7d. These returns have been disappointing, hence the desultory manner in which work was carried on. Four men were employed. Prospecting has also been carried on in the Golden Hill, Leading Wind, Princess May, and other claims in the district, but so far the results have been disappointing. Whangapoua District. The land is chiefly Kauri Timber Company's freehold, and held by the Kauri Gold Estates Company. A large number of men have been employed in prospecting on this and other freehold lands, but no returns of gold have been made. This company is carrying on work in Owera and Otunguru districts. The Maiden Claim at Whangapoua is held from the Kauri Timber Company, and the owners had a parcel of 53 tons of quartz treated, for 16 oz. 11 dwt. of gold ; value, £46 4s. Matarangi District. The Wild Wave, Ocean View, Jumper, Matarangi, and the Ness Side Claims have been prospected, but there is no report of any valuable discoveries. Kuaotunu District. Kapai-Vermont Mine.— This mine has been steadily worked during the year. 3,179 tons of quartz crushed yielded 3,332 oz. 5 dwt.; value, £7,151 18s. 10d., or at the rate of £2 3s. Id. per ton, being a decrease of 2,876 oz. 15 dwt. compared with the previous year's yield. The principal works carried on were driving a distance of 500 ft. on the reef at the No. 2 or low level and putting up a rise 108 ft. to connect with No. 1 level. 272 fathoms of reef were stoped over No. 2 and 571 fathoms above No. 1 level. The mill used for crushing is an Otis ball-mill, which reduces 13J tons per day*
C—3
50
Continuous crushing was not carried on, the mill being kept running only 237 days, of twenty-four hours each, during the year. The ore is dried in five kilns, each capable of holding 80 tons of quartz. There is, however, a revolving furnace in course of erection, which is to be used in place of the kilns for drying the ore. The cost of mining the quartz is 18s. 7d. per ton, and of milling and cyanide.treatment 16s. Id. per ton. Twenty-four men were employed at the mine and eleven at the mill. This mine is under offer to an English company, but negotiations were not completed at the 31st March. The manager, Mr. J. B. S. Wilson, says, " For future works I have recommended to sink to a depth of 200 ft. or 300 ft. to prove the value of the lode below the present workings, and if found to be payable, then to start a main shaft on our eastern boundary, and sink to cut the underlie of the reef. The pumping and winding would only be to our present low level, and quartz could be conveyed to the mill on our present tram-line. The crushing machinery recommended is a Krupp mill to work in conjunction with the present plant, and eight vats and sumps in addition to the eight vats of 22-ton capacity used at present." Jupiter Mine (Area, 300 acres). —This property is situated to the southward of the KapaiVermont, and has been prospected by a tunnel 600 ft. near the south boundary of that mine. The rock was of a hard nature for some distance, but has lately been of a more kindly character, 100 ft. must yet be driven to intersect the line of the main Try Fluke reef. In surface drives and trenches several small veins have been discovered. The object of this company at present is to prospect the property and locate the reefs. Eight men were employed. Mariposa, formerly Try Fluke Mine. —This mine consists of an area of 106 acres, and has been transferred from the Try Fluke Gold-mining Company to the Mariposa (English) Gold-mining Company. In consequence of the change of ownership development works have chiefly been carried on, and the yield of gold is less than that for the previous year. The mine is now well opened up, sufficient quartz being in sight to keep a much larger number of stamps at work. Fifty-two men were employed. Mr. John Goldsworthy, the mine-manager, gives the following description of the mine-workings and machinery used in the treatment of the ore : — The mine is opened out at four levels ; the depths from the surface are : No. 1 level, 100 ft.; No. 2, 200 ft.; No. 3, 320 ft.; No. 4, 440 ft. The No. 1, or Try Fluke, reef has been driven on and worked to a considerable extent in the levels above mentioned. No. 3 lode has also been worked at No. 2 and No. 3 levels, and has produced a large quantity of payable ore. No. l,or Try Fluke, reef varies in size from 1 ft. to 20 ft. in thickness, and has been worked at Nos. 1, 2, and 3 levels, producing a large quantity of payable ore. The machinery used for crushing is as follows : One fifteen-stamp mill and two berdans, driven by a 20-horse-power steam-engine. The weight of each stamp is 9 cwt. The cyanide plant consists of four vats (capacity, 20 tons each), two sumps, one dissolver, and one solution storage-vat. This plant is capable of treating 25 tons per day. The ore is treated by the wet process, and is crushed in the usual way by stampers. The whol9 of the crushed ore passes over copper-plates, and the principal portion of the coarsest gold is saved by quicksilver amalgamation on plates and berdans. The whole of the tailings are caught and saved in pits outside of the mill. The tailings are drained fairly dry, and then trucked into the vats and treated with cyanide solution. The extraction is satisfactory ; there is very seldom more than from 16 gr. to 24 gr. of gold per ton left in the tailings after treatment. The mill has not been running full time. We have, however, put through 5,305 tons of ore, for a return of 1,865 oz. of gold ; value, £4,150 os. Id. Battery returns, 1,050 oz. ; cyanide, 815 oz. The mill at the present time is only working one shift, and is used more as a plant to test the value of the ore in the various levels. The object of the new company is to thoroughly open up the mine by driving on the reefs at the various levels. There is over 1,200 ft. to drive on the main reef, and also on No. 2 lode, with backs varying in depth from 140 ft. to 160 ft. from No. 3 level. At No. 4 level we have still about 1,800 ft. to drive on the No. 1 and No. 2 reefs, with backs of 140 ft. untouched for the whole distance. Development works are now being pushed on, and contracts are let for driving on the No. 1 and No. 2 reefs at the various levels. At No. 3 level, Fluke section, we are driving, rising, and sinking on the No. 1 and No. 2 lodes. We are also driving a cross-cut east of any of the lodes at present being worked, for the purpose of prospecting the eastern portion of the company's property. We are also driving south in the Venus section of the mine, on the Bed Mercury and Try Fluke lodes. In Mariposa section drives north and south are being driven on the main reef. At No. 4 level the main drive on the reef has been driven about 560 ft., and a rise put up to No. 3 level. We are also sinking a winze on No. 2 reef from No. 3 level; the depth is 100 ft., and we expect to hole through to No. 4 level in a short time. The cost per ton for mining ore, not including development work, is about Bs. ; cost per ton for crushing, ss. ; cost per ton for cyanide treatment, including labour, 4s. 11-Jd. The object of the company is to open up the mine, with a view to working on a large scale, with increased crushing-power. Plans are now being made for a forty-stamper mill, with all the latest improvements, which will shortly be erected. Great Mercury Mine (Area, 28 acres 12 roods). —This mine is situated on the spur lying to the northward of the Mariposa, late Try Fluke, and between that mine and the Irene. The ground is well opened up, and operations were carried on for a portion of the year only, protection having been granted for the claim. About 3,772 tons was crushed, for a yield of 1,579 oz. 7 dwt.; value, £1,328 6s. 4d. Twenty men were employed. Irene Mine (Area, 57 acres). —This mine is now held by the Irene (Hauraki) Gold-mine (Limited), London. The mine is opened by three cross-cuts —No. 1, 290 ft. long, 190 ft. below top of hill ; No. 2, 150 ft., 220 ft. below top of hill ; and No. 3, 250 ft., 297 ft. below top of hill. A lower level cross-cut has been driven 230 ft. 443 ft. below top of hill. Driving was done on the reef at No. 1 level 150 ft., at No. 2 450 ft., and on the intermediate level 175 ft. The main reef averages from 3 ft. to 4 ft., and dips slightly to the eastward. There are other reefs in the ground, but sufficient work has not been done on them to show their general characteristics. The mill consists of ten stamps, 950 lb. each, and five berdans, with a cyanide plant of one 20-ton leaching-

vat, sumps, &c. The motive-power for the mill is supplied from a 30-horse-power horizontal steam-engine with steel tubular boiler. The mill was run about two weeks during the year. At the time the property was held by the former owners 45 tons of quartz was treated, and, together with 100 tons of tailings, yielded 82 oz. of bullion. Since the property was acquired by the present company development only has been carried on, no ore being treated. Up to the 31st December last five men were employed ; since that time twelve men. Invicta Mine (Area, 18 acres). —A considerable amount of prospecting work has been done on the surface portion of the mine by driving cross-cuts. In the workings on the main reef, which varies from 3 in. to 3 ft., 37 tons of quartz was taken out and crushed, for a yield of 190 oz. 2 dwt. of gold; value, £370 9s. lOd. Three men were employed. Juno Mine (Area, 28 acres). —A low level has been driven at a depth of 160 ft. below the surface workings. A rise was put up on the reef for a distance of 35 ft. The reef is from 6 in. to 2 ft. 6 in. in thickness. 22-| tons of quartz crushed yielded 87 oz. of gold. Five men were employed. Gladys Mine (Area, 29 acres 2 roods). —This mine is adjacent to the Irene, to the westward. A considerable amount of driving has been done on the land, and several reefs cut, No. 1 reef being about 2 ft. in thickness. Mr. John Goldsworthy, jun., the mine-manager, gives the following description of the workings : — Three levels are opened. Depths from the surface : No. 1 level, 60 ft.; No. 2, 100 ft.; No. 3, 90 ft. There are two well-defined reefs traversing the ground, besides other smaller leaders. The No. 1 reef varies in size from Ift. to 2 ft. (course, about north and south), is a well-defined lode, carries a little gold throughout, and is in a good class of country. The No. 2 reef, near the eastern boundary, is also a well-defined reef from 2ft. to 3ft. through; course, about north and south. The ore from both these reefs is clean free-milling ore. The mine has been developed by means of tunnels, winzes, &c. On the eastern side of the ground, near the Irene boundary, a tunnel has been driven through the hill a distance of over 500 ft. From the centre of this tunnel we have driven south a distance of 170 ft. on a leader, and have also put up a rise at the end of this drive to the surface, a distance of 70 ft. On the No. 2 reef we have sunk a winze to water-level, a distance of 25 ft. On the western side of the ground, near the Juno boundary, we have driven in No. 1 level (north and south on No. 1 reef) a distance of 140 ft., and from this level have sunk a winze a distance of 60 ft. We are now driving a lower level to intersect this reef, which will give us over 100 ft. of backs, and will connect with the winze above mentioned. The assay-value of this ore is £2 per ton. Besides these workings, we have done a considerable amount of prospecting by means of trenches, surface drives, &c, and have cut several smaller leaders, from which a little gold can be got by dish-testing. The average number of wages-men employed for the year is four. Handsworth Mine (Area, 5 acres 2 roods). —This mine is situated to the northward of the Irene. The reef which has been worked on was cut in a tunnel driven a few feet above the level of the flat. A parcel of 35 tons of quartz was crushed at the Thames, for a return of 94 oz. of gold. Three men were employed. A considerable amount of prospecting has been done in the following claims, and quartz reefs discovered, but beyond a few colours by pounding and washing no further results have been reported to me : Midas, Ajax, Golden King, Great United, Balfour, Mount Aurum, Alpine Fluke, Diadem, Phoenix, National, Aurora, Golden Link, Norena, Empire, Brilliant, Antelope, Heather Bell, and Vulcan. Aorere Mine (Area, 100 acres). —A considerable amount of driving has been done on the reef, from which the tributers obtained gold to the value of £129 Bs. 9d. in the previous year. No quartz has been crushed during the year. Four men were employed. Lincoln Mine (Area, 126 acres). —A considerable extent of driving was done near the surface, and several reefs cut, which are said to give prospects of gold by mortar tests. The surface level was driven through blue clay, and when the supposed reef was met with it did not reach the bottom of the drive, but formed a roof for 40 ft. It is highly probable that this mass of quartz is the result of thermal action ; hence the soft clay underneath the surface deposit. Three men were employed. Kuaotunu Mine (Area, 100 acres). —A prospecting tunnel has been driven 540 ft., and a number of small stringers cut, but no large reef was met with. Four men were employed. Maori Dream Mine (Area, 100 acres). —The chief work during the year has been in opening up the mine. Three levels are now open, two of which will give 200 ft. of backs on the reef, which varies from Ift. to 19 ft. in thickness. The lowest level will also give 369 ft. of backs on the reef. Upwards of 600 ft. was driven on reefs, and the manager, Mr. A. H. Richards, informs me that the prospects of the mine are excellent, and that good returns will be obtained as soon as the proposed machinery for treatment of the quartz is erected. Eight men were employed. Maoriland Mine (Area, 100 acres). —This mine is now owned by the Maoriland Gold-mines (Limited), of London. The chief work carried on was in development of the No. 1 reef, varying from 6 in. to 5 ft. ; No. 2 reef, 18 in.; and No. 3 reef, 5 ft. in thickness. The adit-level tunnel, when driven in 600 ft., will give from 400 ft. to 500 ft. of backs on the reefs, and the depth from this tunnel to sea-level is 85 ft. Five men were employed. Carnage Mine (Area, 100 acres). —Three reefs of 4ft. in thickness each and one reef 7 ft. in thickness have been discovered, and about 250 ft. of driving was done. The quartz does not appear to be of great value. A parcel of 2 tons crushed at the Thames School of Mines yielded 9 d.wt. 14 gr. of gold. Four men were employed. Prospect Mine (Area, 100 acres). —The work carried on during the year was sinking a winze on the reef from No. 1 level and extending the No. 2 level 120 ft. This is now within 60 ft. of the bottom of the winze. A network of quartz veins, varying from lin. to 7 ft., has been cut in the eastern cross-cut, one of which, about 18 in. thick, consisting of rubbly quartz, prospects fairly well. Six men were employed. B—C. 3.

Waitaia Mine (Area, 85 acres 2 roods). —This mine is situated near the top of the range dividing the Kuaotunu and Waitaia watersheds. The land being precipitous gives facilities for opening the mine from surface drives: No. 1, a surface level, 36ft. ; No. 2 level, 320 ft.; No. 3, 380 ft. ; No. 4, cross-cut, 280 ft. ; No. 5, cross-cut, 309 ft. The principal work done during the year was extending the drive on No. 3 reef at No. 4 level 180 ft., extending the drive on Barrett's reef 60 ft. at No. 2 level, rising on Barrett's reef 40 ft., driving on No. 5 reef 23ft., driving on No. 4 reef Bft., rising on No. 3 reef from No. 4 level 50ft., and driving No. 5 cross-cut 309 ft. When this cross-cut has reached the reef the country will be drained and the mine well opened up. The different reefs vary from 2 in. to 6 ft. in thickness. 81b. of picked stone yielded 6oz. 10 dwt. of gold. The number of men employed was nine. The present owners are in treaty with an English company for the purchase of the mine, and no machinery has been erected pending completion of negotiations. Golden Anchor Mine (Area, 146 acres and 17 perches).—There are nine gold-bearing reefs, varying from 1 ft. to 15 ft. in thickness, and generally of a flinty character, already discovered in the ground. About 237 ft. of driving has been done on the different reefs, and a cross-cut 328 ft. has also been driven to prove the value of the reefs at a depth of 300 ft. from the top of the hill. Seven men were employed. Neio Mint Mine (Area, 27 acres). —Work was commenced on the ground in August last. Quartz was discovered in surface trenches, and good mortar prospects of fine gold obtained from No. 2 reef. A cross-cut is being driven to cut this reef at a depth of 100 ft. from the surface. 196 ft. must be driven before the reef is reached. Four men are employed. Premier Mine (Area, 77 acres). —A considerable amount of surface trenching and cross-cutting was done and four reefs cut in the low level, 100 ft. below surface. A drive was put in on No. 2 reef for 20 ft., on No. 3 reef 47 ft., and on No. 4 reef 63 ft. The reefs vary from 2 in. to 4 ft. in width. Four men were employed. Superb Mine (Area, 100 acres). —Four reefs have been discovered on this property, one of the reefs apparently being hard conglomerate quartz about 3 ft. in thickness. Three men were employed. Al Mine (Area, 105 acres). —This claim has been amalgamated with the Oriental Mine, and a considerable amount of prospecting work has been done. Three cross-cuts were driven : No. 1, 50 ft. ; No. 2, 235 ft.; and No. 3, 66 ft. Several quartz veins were cut, from Ift. to 3 ft. in thickness, and 28 tons of quartz was crushed, for a yield of 6 oz. of gold. A fresh cross-cut has lately been put in, intended to reach a reef from which good dish prospects were obtained on the surface. About 70 ft. of driving will cut the reef. Four men were employed. Wheal Bassett Mine (Area, 94 acres). —There are five reefs opened, in this mine on No. 1 reef, which is 3 ft. in thickness, and the quartz of a promising character. Prospects of gold are obtained by pounding the stone in a mortar ; in No. 5 reef also a few colours of gold are obtained by pounding. The quartz formation is 8 ft. in width, white, and of a friable character. Five men were employed. Opito and Kuaotunu No. 3 District. A number of claims have been taken up, but no returns of gold have been received. Mahakirau District. A number of claims have been taken up in this district, and extensive prospecting work carried on, but no return of gold has been received. Moewai District. Areas taken up and prospecting done, but no return. Hahei District. No record has been given of any discovery in the land taken up. Boat Harbour District. Very little work has been done here, and no valuable discovery has been reported. Kauri Gold Estates Company. This company now owns the following blocks of land, taken over from the Kauri Timber Company for mining purposes : Otanguru, 4,092 acres; Owera, 4,502 acres ; Wairoa, 444 acres; Opitonui, 8,837 acres; Waitekauri, 4,190 acres; Te Ranga, 467 acres; Hikutawatawa, 1,650 acres ; Kaeaeu, 88 acres ; Hurungoherehere, 533 acres; Moewai, 882 acres; Weiti No. 1, 2,315 acres ; Whakau, 933 acres ; Kaimarama, 1,600 acres ; Willis's, 1,797 acres ; Graham's, 1,650 acres ; Taparahi No. 1, 3,078 acres ; Matakitaki, 1,010 acres ; Ngarahutunoa, 210 acres; Maungatapu, 32 acres; Opera, 20 acres ; and Whangapoua, 62 acres. On the company obtaining possession of these lands active prospecting operations were at once commenced, a staff of about a hundred men having been employed. Operations were resumed in opening up the Lanigan's Mine at Whangapoua, the Owera, and also the Otanguru Mines, and machinery for pumping is being imported to sink one or two shafts in the Whangapoua district. The company secured the valuable services of Mr. A. Montgomery, formerly director of the Thames School of Mines, and latterly Chief Inspector of Mines for Tasmania. The large area of land held, and the many localities where the rock is of a promising and "kindly" character, favourable for gold-bearing reefs, indicate that mining operations will prove of a successful nature, especially as, since the opening of the Coromandel Goldfield, rich parcels of gold-bearing quartz have from time to time been obtained from several of the above-mentioned blocks of land.

General Bemarks. The Hauraki Mine has still continued the chief gold-producer in this district, although there has been a considerable falling-off in the yield of gold. It will, however, be some time before the lower levels in this mine, the Kapanga, Success, Scotty's, Tokatea, and other mines can be opened up in such a manner as to produce continuous yields, and unless other rich shoots of ore are met with in the meantime an immediate increase cannot be looked for in this quarter. In the Kuaotunu district, at the Kapai-Vermont, Try Fluke (now Mariposa), and Great Mercury Mines, more attention has ■ been given to mine-development than making the most with the present machinery of the ore immediately in sight. As those mines are now held by English owners, whose policy is to explore the mines thoroughly, and erect suitable plants for treating large quantities of ore, no great addition to the returns can be expected from Kuaotunu until after the new machinery is in operation. During the year 18,748 tons 5 cwt. 481b. of quartz was treated in Coromandel County, for a yield of 35,846 oz. 10 dwt. of gold, and 100 tons of tailings treated by cyanide yielded 40 oz. ; the whole valued at £100,911 os. lOd.; whilst 1,329 men were employed in connection with the mines. Thames District. The Thames portion of the Hauraki district lies to the southward of Coromandel, and the country is of an extremely rugged and broken character. A large number of mining properties are situate within this district, including the Thames-Hauraki Goldfields (Limited) Deep Levels Drainage-shaft, the famous Caledonian, Moanataiari, Prince Imperial, Waiotahi, and other wellknown mines, which are within the boundaries of the Thames Borough. The development of the mining industry in this portion of the Hauraki district is exemplified by the following list of mining properties taken up : —

Mata District. Mata Beefs Mine (Area, 176 acres). —This mine is situated near the junction of the Gentle Annie and Mata Creeks. The northern, or Mata, section includes the Mata and Jay Gould Claims. It is intended to reopen the workings on the hill, where gold was obtained several years ago. In the southern section, known, as the " Nikau Valley," there is a large reef of 20 ft. in width, from which good dish prospects are obtained. Several other reefs and leaders have been discovered, but not yet prospected. There is water-power available for driving machinery, and many facilities for working this property. Kelly's Claim (Area, 38 acres). —The work carried on in this claim has been sluicing the surface, with a view of discovering the reef from which the gold found in the creek was derived, but the efforts in that direction have not yet been successful, and no return of gold has been made. Three men were employed. The Marquis of Salisbury, Mata Prospectors, Canadian, Clematis, and Parnell Claims have been taken up, and more or less prospecting work carried on. Tapu District. Golden Point Mine (Area, 120 acres). —The shaft was sunk to a depth of 210 ft., and a level opened in the cross-cut towards the line of reef. A number of stringers, showing visible gold, were cut, and a rise put up to the old workings. So far the returns have not been very great. A crushing of 4 tons of quartz yielded 1 oz. 4 dwt. gold ; value, £3 per ounce. Thirteen men were employed. Sheridan Mine (Area, 100 acres). —The main adit has been extended to a distance of 800 ft., and 150 ft. will yet have to be driven to cut the main reef at 400 ft. below the surface. A considerable amount of stoping was carried on by a party who held an option on the mine, and 199 tons crushed yielded 197 oz.; value, £591. Eight wages-men were employed. Golden Horn Mine (Area, 21 acres and 20 perches).—This mine is situated to the southward of Tapu Creek, and about a mile from the sea. Prospecting work has been carried on, and a low level driven 370 ft., and four reefs cut from 3 ft. to 8 ft. in thickness, in which a little gold is got by pounding and dish prospecting. A crushing of 14 tons yielded 2 oz. 14 dwt. ; value, £8 2s. Four men were employed. Comet Mine (Area, 45 acres 2 roods 15 perches).—The principal work carried on during the year was in extending the low-level cross-cut. The shoot of gold worked in the early days of mining at Tapu Creek yielded 1,8000z., and this cross-cut is being put in in hopes of cutting the same leader at a greater depth. Four men were employed. A considerable amount of prospecting has been carried on in the following mines : Eoyal Extended, Sylvia Park, Eoyal, Shannon, Golden Band, Square and Compass, and Mahara. It is the intention of the Mahara Company to erect a battery of ten stamps in the vicinity of Eogers's farm. The battery will prove a boon to the claimholders in this part of the district, as affording them a means of testing the value of their reefs. Waiomo District. Monoiocd Mine (Area, 87 acres 3 roods 29 perches).—During the year 50 tons of quartz was crushed, yielding 29 oz. 12 dwt. ; value, £95 14s. 4d. The method of treatment introduced by Mr. A. G. French was after some time dispensed with, and the mine and mill both were at a standstill, no further quantity of quartz being crushed. The property is now owned by the Monowai Gold-mines (Limited), an English company, and the manager, Mr. A. S. Gabbs, is carrying on three drives for the purpose of developing the reefs. Benown Mine (Area, 100 acres). —A drive has been put in for a distance of 190 ft. to cut a large reef which outcrops, showing a width of 20 ft. Four men were employed. Bangatira Mine (Area, 53 acres 3 roods 20 perches). —This mine is situated near the beach. A drive has been put in for a distance of 378 ft., and a reef cut about 8 ft. in thickness. A crushing of 10 tons of quartz yielded 2 oz. 19 dwt.; value, £8 17s. Four men were employed. A considerable amount of work has been done in prospecting the large reefs formerly discovered in the Mount Morgan, Broken Hill, Comstock, and Mount Zeehan. A number of claims have been taken up in an easterly direction —namely, the Polydorus, Emerald, Topaz, Bronte's, Pactolus, and others —but so far there is no record of any valuable discovery. Puru District. Prospecting work has been carried on in the Waipuru, Sunlight, Orion, Ulysses, Wonona, New Boss, and also in the Big Eeef, in which a large body of quartz has been discovered. In the Puru Main Lodes, Eimutaka, Digger's Dream, Pakeha, Waimea, and Morion work has also from time to time been carried on, and this portion of the district proved to contain large reefs of quartz. Puru Consolidated. —This claim comprises the Eussell, 93 acres 2 roods; Uranus, 100 acres; Eussell Extended, 100 acres ; and Salisbury, 98 acres 2 roods. A considerable amount of work has been carried on in the development of the Eimu reef. A drive has been put in at No. 2 level, which will give a block for stopiug, with backs over 70 ft. in height. It is the intention of the owners to erect crushing machinery on the ground. A small parcel, consisting of 2 tons of quartz, was crushed, for a return of 3oz. 16 dwt. ; value, £10 10s. Seven men were employed. Tararu District. Tararu Greek Mine (Area, 159 acres). —This mine is being steadily developed. The No 1 level, 306 ft. below surface; No. 2, 376 ft.; No. 3, 582 ft.; No. 4, 609 ft.; and No. 5, or low aditlevel, 638 ft. below surface, have each been further advanced, and stoping has been carried on.

2,521 tons of quartz was crushed, for a yield of 795 oz. 16 dwt. bullion, valued at £2,386 16s. Bd.; and 1,000 tons of tailings treated by the cyanide process, for a yield of 1,215 oz. 10 dwt., value £797 10s. 6d. : total value, £3,184 7s. 2d. The low-level adit near the battery has been driven 332 ft., and is now 1,782 ft. in length. It is intended to connect this as early as possible with the level above in order to effect communication with the more distant portions of the mine, and obviate the necessity of carting the quartz from the other levels, which is found to be very expensive. The mill consists of twenty head of stamps used for wet-crushing and amalgamation, whilst three vats (two each of 25 tons and one of 50 tons capacity) are used for the cyanide process. Sixty men were employed. Mr. W. H. Argall, the general manager of the company, gives the following description of the mine-workings and of the machinery employed for treatment of the ore :— Since the present company started operations the following work has been accomplished: At the battery, or main-adit, level a distance of 1,450 ft. of cross-cutting has been put in repair, and a further distance of 610 ft. has been driven on the line of reef. The lode where last passed through showed a width of 36 ft. at 638 ft. from the surface. I may mention that this adit or tunnel is being made large enough to admit of a horse or small locomotive being used, and when completed will be the main outlet for the whole of the mine. The principal work at present being carried on is at the Dunedin level, which is 119 ft. above the main adit. A cross-cut of 283 ft. has been put in, and both the City of Dunedin and the Star of California reefs have been intersected. On the City of Dunedin lode 1,188 ft. has been driven, and 66 fathoms of stoping done. The reef varies from 2 ft. to 16 ft. in thickness, the ore being of a free-milling nature. On the Star of California reef .73 ft. has been driven, the lode showing a width of 3 ft. The Wild Missouri, or No. 4, drive is 70 ft. above the Dunedin low level. A considerable amount of work has been done in this drive. 1,021 ft. of cross-cutting is now opened up, together with 1,723 ft. driven on the line of reef (Californian reef). A block 200 ft. in length and 180 ft. in height has been stoped out. The reef varies from 1 ft. to 8 ft. in thickness, and may be considered of a complex character. On the Day Dawn line of reef two levels have been opened up. In No. 1, 249 ft. have been driven; No. 2, which tests the reef at a depth of 330 ft. from the surface, has been carried along a total distance of 507 ft., 307 ft. of which are on the line of reef. On this line 196 fathoms of stoping has been done, the lode all through varying from 2 ft. to 7 ft. in width. This ore is also of a complex nature. The battery consists of forty head of stampers, driven by an overshot water-wheel. At present only twenty head of these are in use. The mode of treatment of the ore is by wet-crushing and passing over amalgamating plates and blankets. The blanketings are then ground in berdans, of which there are six in use. The tailings are caught in buddies, and afterwards subjected to cyanide treatment. The cyanide plant consists of three steel vats, with necessary sumps, extractors, dissolving-tank, and solution-pump, capable of treating 100 tons per week. At the different levels there are fully 30,000 tons of ore in sight. City of Auckland Mine (Area, 100 acresj.—This mine comprises portion of the land formerly known as the Sylvia Mine. The old adit has been cleared for a length of 1,100 ft., and a shaft is being sunk to test the reef at a greater depth. Seven men were employed. Kaiser Mine (Area, 49 acres). —This mine is also a portion of the old Sylvia property. Prospecting operations were carried out on various reefs, but no gold was struck until the beginning of February last. The new reef, when cut, was 2 ft. 6 in. in width for the first 35 ft., and was composed of clean free-milling ore; for the next 20 ft. the reef is highly mineralised, containing galena, ironpyrites, copper-pyrites, and zinc-blende. The quartz is sometimes rubbly and at other times solid. Two parcels of ore were treated—lß cwt. at the School of Mines, for bullion of the value of £5 155.; and 15 cwt. by Fraser and Sons, Auckland, for a value of £6 7s. lOd. Six men were employed. Vulcan Extended Mine (Area, 186 acres). —This land is situated at Upper Tararu, and includes the ground known as the Vulcan, which was worked by a company in the year 1870. A battery was on the ground when formerly occupied, and a large quantity of quartz crushed, which yielded profitable returns. The mine is now being prospected by the Thames Exploration Syndicate, which holds an option on the property. There are several known lines of reef traversing the land, all gold-bearing. Six men are employed in driving a prospecting tunnel and cross-cutting near the surface. A parcel of 1 ton of quartz was crushed at the Thames School of Mines, for a return of 4 oz. 11 dwt.; value, £11 17s. Argosy Mine (Area, 183 acres). —This mine is situated on the ridge to the northward of Tararu Creek. A considerable amount of prospecting has been done, and four cross-cuts driven—No. 1, 95 ft.; No. 2, 40 ft.; No. 3, 140 ft.; and No. 4, 40 ft. Several gold-bearing reefs have been cut, averaging 2 ft. in thickness. The prospects are encouraging, and would warrant more exhaustive exploration. Eight men were employed. Prospecting operations were also carried on in the Golden Opportunity, Bonanza, Waratah, Temple Bar, Scottish Chief, Vulcan, Tararu Extended, Ake Ake, Conservative, Nuhaka, Clunes, Star of Tararu, Mount Taylor, and Lomas. Scandinavian Mine. —This mine was worked for a considerable part of the year by the Scandinavian Company. A crushing of 145 tons of quartz yielded 55 oz. 1 dwt. of gold ; value, £154 2s. 9d. Negotiations are in progress to dispose of this mine to an English company. Seven men were employed. Kuranui District. Kuranui Mine (Area, 15 acres). —A considerable amount of work was done in driving at the 70 ft. level, and prospecting on the Oddfellows and other reefs. A parcel of 20 tons crushed yielded gold valued at £4 14s. sd. Four wages-men were employed. The Magazine and several other claims have been prospected. Kuranui-Caledonian. —This mine comprises the Hazelbank and Comer's Kuranui. A tramway has been constructed from the Caledonian shaft to the battery formerly owned by Mr. Comer, and
.—3
379 tons of quartz crushed yielded 599 oz. 19 dwt. melted gold, valued at £1,629 14s. 2d. During the year the shaft has been repaired, and is now in good order down to the bottom, No. 4 level (474 ft.). This level has also been cleaned up and repaired to the Big Pump shaft. The drive on the course of No. 1 reef is also being cleaned out, and it is intended to push this drive on and connect with the Moanataiari new shaft. This will give splendid ventilation, and allow works to be carried on to more advantage. The most of the quartz crushed was won from No. 1 level, on reefs known as Darby's, Cross reef, and. Kelly's. The battery consists of twenty heads of stampers driven by a Pelton wheel 6 ft. in diameter. Seventy men are employed in the mine and battery. Moanataiari Mine. —This mine is one of the oldest on the Thames Goldfield. It was opened in 1868, and has been worked continuously ever since. At the time the mine was first opened the area of ground held was only a few acres in extent, but as time went on all the small adjacent claims were purchased by the proprietors of this mine, until the area now held is 95 acres, the whole of which is on the richest belt of this goldfield. A large amount of gold has been obtained from this mine, and dividends amounting to nearly £200,000 have been paid to the shareholders; but this gives a very faint idea of the value of the property, inasmuch as that if the assay-value of the whole of the ore treated from this mme —some of it was opened twenty-nine years ago—had been ascertained it would be found that, owing to the primitive appliances used in the early days, not more than 40 per cent, of the value of the gold the ore contained had been recovered. Although rich bonanzas of auriferous ore have been found from time to time in this mine, a very large amount of dead-work had to be undertaken in the construction of adits, levels, shafts, and winzes to open it up and get the workings properly ventilated, and when rich shoots of ore were worked, the shares rose on many occasions to high prices, and rapidly exchanged hands. The principal object in working the mine was to keep all hands working on the rich shoots, so that large dividends could be paid. A reserve fund was never thought of, to undertake fresh dead-work to open out fresh blocks of ore calls had to be made, and new shareholders, who had purchased shares at high prices with the expectation that the mine would steadily continue a large dividend-paying concern, were not in a position to meet the calls, and this has led to the company being reorganized at three different periods. The last reorganization of the company took place in November, 1896, when the mine and plant were purchased by an English company, with a working capital of £30,000, and which has since been increased to £50,000. This company's head office is in London, and is represented in the colony by its attorney, Mr. Henry A. Gordon, general manager of the Anglo-Continental Gold Syndicate (Limited), the late Inspecting Engineer of the Mines Department. The mine is being well opened up, a large amount of development having been done during the year. No. 2 shaft has been sunk a further depth of 246 ft., making the total depth from the surface 400 ft. The main adit, or Moanataiari Tunnel, was extended, and has now reached a distance of 3,170 ft. from the entrance. In driving the various cross-cuts 950 ft. has been completed, and 2,084 ft. of driving on reefs and leaders ;in rising and sinking on reefs 550 ft. has been done. The total quantity of quartz crushed during the year was : For the owners, 5,073 tons, value £1 Is. per ton ; and for tributers, 375 tons, value £1 lis. per ton : total value, £5,907 18s. The whole of the crushing plant has been dismantled, in order that a new and improved plant may be substituted. The mine will be so well opened that on completion the new battery can be fully employed. The prospects of the mine are very favourable. The extent of reefs explored and ready for stoping out will, when worked, yield profitable returns, as pockets of rich quartz similar in character to the bonanzas taken out in the past are almost certain to be met with. The increased quantity of quartz that in future will be required to supply the new mill will necessitate taking out blocks of reef that were left because apparently not payable. The average value of the whole when rich pockets are included will give a satisfactory yield. It is highly probable that exploration of greater depths near the Main Slide and under where the heavy deposits of gold were obtained from No. 9 reef will result in the discovery of a continuation of rich patches. The extension of the main tunnel will also enable the well-known rich reefs and leaders to be opened at greater depth than could have been undertaken in the past, and add in a great measure to the extent available for working. The return of gold for next year cannot (unless a very rich pocket is met with) be expected to come up to the yield for 1896, as during the greater part of 1897, until the new mill is ready, no quartz can be treated. Eighty-five wages-men and twelve tributers were employed. The following account of the mine, the new works carried out, and the improved crushing-mill has been furnished by Mr. H. A. Gordon, the resident general manager, and gives a correct description of the whole : — At the time the present company took over the property the mine was in a very bad condition. All the known shoots of payable ore on the upper levels had been taken out, and the levels, adits, and shafts allowed to fall into a very bad state of repair. The main adit, known as the Moanataiari Tunnel, which was constructed for a distance of 3,070 ft., had to be retimbered and new roadways laid down before workings could be proceeded with in other portions of the mine, this adit being the main highway to get the ore conveyed from all portions of the mine to the crushing-battery. The main adit has been extended for a distance of 100 ft., and a cross-cut constructed from it for 150 ft., where it cut the Eeuben Parr reef. This reef has now been driven on for a distance of 110 ft., and will require a further extension of the level of 550 ft. to get under the rich shoot of ore which was found in opening up the level 200 ft. above this, which is termed the 100 ft. level. The total distance to drive on this reef from the present face on the main-adit level to the eastward boundary of the property is 1,200 ft. The whole of this reef where the rich shoot of ore was cut through on the 100 ft. level is intact to the surface, the main-adit level at this point being 550 ft. under the outcrop. This lode has been opened up for a distance of 700 ft. on the 100 ft. level, and also for the same distance on the Point Eussell level, ready for stoping as soon as the new mill, which is at present in course of construction, is completed. Among other important works undertaken is the development of the Golden Age reef, one of the principal lodes which traverses the whole, of the property. This has been opened out
62
63
0— 3
for a distance of 750 ft., and also for a distance of 100 ft. on the Point Russell level, all ready for stoping, with 200 ft. of available backs. It will also soon be cut at the main-adit level, which, from its course and underlie, will join with the Eeuben Parr reef at this depth. A cross-cut has also been constructed from the Golden Age reef, on the 100 ft. level, for a distance of 600 ft., and the Waiotahi lode cut, but very little driving has yet been done on this lode to ascertain its value. In the western section of the mine, which comprises the seaward side of the Great Moanataiari Fault, a new shaft 12 ft. by 5 ft. 6 in. in the clear has been sunk on the south side of the Moanataiari Creek, and is now down to a depth of 400 ft. Two levels have been opened out from this shaft, one at 150 ft. below the main-adit level and another at about 90 ft. lower depth. These levels correspond with the old levels constructed many years ago from No. 1 shaft sunk on the northern side of the main adit. All the old levels have been cleaned out and repaired, ready to stope out the different blocks of ore which were left in the early days on the Caledonian reefs, Nos. 1, 2, and 9, A cross-cut has also been constructed from the main adit to the new shaft, where a chamber is constructed, and where all the ore from the deep levels will be landed and conveyed through the main-adit level to the battery. The new shaft will be sunk another 100 ft., and levels opened out on the Caledonian reefs, which will give about 140 ft. of backs on all these reefs, as no work has been done in any of them below the levels at present opened out. Another important work now in course of construction is a cross-cut from the new shaft at a depth of 250 ft. below the main adit to cut the Waiotahi reef, which is now driven on for a distance of about 160 ft., leaving yet 570 ft. to construct before it will intersect the lode underneath the place where the rich bonanza of ore was found in the Cambria Mine. This will give about 125 ft. of backs on this lode before the reef passes into the Cambria ground, the length available of the reef at this place being about 600 ft. The whole of the work in this mine is entirely confined to prospecting and development. The object of the company is to thoroughly open up every portion of the mine, so that a large and continuous supply may be got to keep the new crushing-mill, when erected, going. In order to carry out the development works expeditiously, a large air-compressing plant has been erected, capable of working four rock-drills at one time. A new double-cylinder steam winding-engine has been erected at the shaft, the cylinders being 12 in. in diameter, fitted up with winding-drums 7 ft. in diameter, with powerful brakes and a winding-indicator, the steam being supplied from a new multitubular boiler; all of which were manufactured by Messrs. Price Brothers, of Thames. The crushing-mill formerly used by the old company, consisting of forty heads of stamps, two pans, and twenty-one berdans, has been dismantled and removed, and in lieu thereof a new plant is in course of construction by Messrs. Price Brothers, of Thames. A large portion of the old battery building had to be taken down, but this is to be re-erected at the rear of the mill building, where a cyanide plant is to be placed. The new battery consists of sixty heads of the heaviest stamps yet used in the colony; each stamp when new weighs 1,050 lb. These are to be driven at a speed of ninety-five blows per minute, and will be capable of crushing about 4 tons each stamp per day. The stems are made of mild steel, 3Jin. in diameter and 15ft. in length, and fitted with steel reversible tappets or discs, made on the most modern design, and are held to the stem with three side cotter-keys in each tappet. The mortar-boxes are made on the Homestake pattern, being fitted with copper-plates coated with silver in the feedingside of each mortar, which has a projecting lip on the inside to prevent any of the ore, as it is fed into the mortars, falling on the plates to damage their surface. The opening in front of the mortars is 4ft. Sin. long by 18in. in height, on the face of which will be placed a wire screen fitted with a wooden frame, and held close to the face of mortar by long taper keys. Each mortar has a base 5 ft. 3 in. in length by 2 ft. in width, the metal in the bottom being 9 in. thick. Inside the bottom of mortar dies of hard steel are placed underneath where every stamp drops, the shoes of the stamps being also made of hard steel. The mortar-blocks are of heart of kauri, each block being 5 ft. 6in. by 2 ft. 3 in. and 18ft. long set on end, the bottom of which rests on a ground-sill, bedded in a thick layer of concrete resting on a solid and stable foundation. Considerable difficulty was experienced in obtaining a solid-rock foundation, but wherever this was not reached two rows of heart of kauri piles were closely driven down to a solid foundation, and a thick bed of concrete placed on the top of the piles, on which the mortar-sills rest. The mortar-blocks are ail down 9 ft. below the surface of the floor of the building, and filled in with concrete. On each side of the concrete foundation concrete walls are built up to within 10 in. of the level of the top of the mortarboxes, to support the sills of the trestles connected with the battery framing, and on the top of which the plummer-blocks rest, which carry the cam-shaft. Each battery of five heads is driven separately by a belt, a driving pulley being on one end of the cam-shaft and a corresponding pulley on the counter-shaft, which runs along the whole length of six batteries of five stamps each. The plummer-blocks to carry this shaft rest on the sills of the trestles at the back or feeding side of the battery, a belt-tightener being provided for each belt. Directly over the centre of the battery there is a gauntree fixed about 5 ft. higher than the upper end of the stems of the stamps, on which a traveller runs from one end of each battery of thirty heads, carrying all the appliances for lifting any of the stamps out of or into the mortars when repairs are required, and it is also strong enough to lift the mortar-boxes into or out of the position. The ore-bins are placed at a sufficient height above the mortars to admit of an automatic Challenge orefeeder being used for each five-stamp battery. The ore-bins, -instead of being constructed with the bottom sloping towards the battery, are flat, and run along the whole length of every thirty heads of stamps, and have a holding-capacity of about 400 tons of ore. The object of having the bins constructed in this manner is to admit of them holding a larger supply of ore, to insure the battery being kept continuously running in the event of the supply from the mine being intermittent. The level of the main adit above sea-level would not admit of the mill being constructed entirely on a gravitation system. The ore could not be delivered at a sufficient height to
C.—3
64
admit of the grizzly and rock-breakers being placed above the ore-bins. These are placed in a wing of the main building, between each battery of thirty heads of stamps, the distance between these batteries being 28 ft. The ore as brought from the mine is dumped on to the grizzlies, and what does not pass through the bars goes down to the rock-breakers, and, after being operated on by them, passes into the same hopper where the fine material going through between the bars of the grizzly falls ; and in the bottom of these hoppers there are ore-gates, underneath which sidetipping trucks are placed, and, when filled, are hoisted up in cages to a platform on a level with the top of the ore-bins by a hydraulic lift, two lines of rails being placed on the top of the bins on which the trucks run to empty the ore where required. There are two rock-breakers, 16 in. by 10 in. face, of the Blake Marsden type; these are driven by a separate Pelton water-wheel. Each battery of five stamps is fitted with an incline table 5 ft. 6 in. wide and 10 ft. long, covered with copper-plate electroplated, and coated with quicksilver, and the pulp from the tables passes on to two concentrators of the improved Frue design; and if the gangue, after passing over these concentrators, proves sufficiently rich it will be lifted by elevators into vats, and treated with a cyanide solution. The concentrates will also be treated either with or without roasting by cyanide solutions, as may be found the most economical. The plant of twenty-one berdans which was in the olid mill is to be re-erected, and will be used if found desirable, and the cyanide plant which will be erected at first will consist of three leaching-vats 20 ft. in diameter and 5 ft. in depth, three sumps 15 ft. in diameter and 5 ft. in depth, one solution-tank, one dissolvingtank and air-pump and vacuum boiler, a centrifugal solution-pump, and two zinc-extractors, with all the necessary appliances of a fully-equipped cyanide plant. The building and everything is so arranged that additional vats can be added as required. The whole of this mill, with all the machinery, is to be driven by Pelton wheels, being supplied with water from the county main. A Pelton wheel is to be provided for each battery of thirty heads of stamps, one for driving the concentrates, and another for the berdans, elevators, and pumps. In order to provide for the mill being kept continuously at work, a steam-engine is being erected for use when a sufficient supply of water is not available, or as an auxiliary power whenever required. The engine is one of Davey, Paxman, and Company's right-hand tandem compound horizontal engines, the highpressure cylinder being 17-|in. in diameter and the low-pressure 20 in. in diameter, provided with automatic expansion gear, special governor and jet-condenser, and air-pump with indiarubber valves. This engine has a stroke of 2 ft. 8 in., and will run at a speed of seventy-five revolutions per minute. It will be capable of giving about 240 indicated horse-power. The engine will be set on a concrete foundation, constructed between the two batteries of thirty heads of stamps. An intermediate shaft will be provided to couple on to the counter-shafts for driving the batteries, and by this means can be connected whenever auxiliary power is required. The steam for the engine is to be supplied by two of Babcock and Wilcox patent water-tube boilers, the steam-drums being 23 ft. long by 3 ft. in diameter, and will be worked up to the pressure of 1201b. per square inch. Moanataiari Extended Mine (Area, 27 acres). —Driving on several reefs was carried on in the surface levels, and 15 tons of quartz when crushed yielded 3 oz. 2 dwt. of gold; value, £8 3s. 6d. Six men were employed. Freedom Mine (Area, 6 acres and 7 perches).—A small party of owners work this ground, but no quartz was crushed. Orlando Mine (Area, 15 acres). —Operations were carried on by the Orlando Gold-mining Company. One hundred tons of quartz was crushed, yielding 35 oz. of gold ; value, £92 3s. 6d. Six men were employed. New Whau Mine (Area, 47 acres). —Operations were confined to clearing out the Middle Star old adit-level and some of the upper levels, and sinking a winze on a reef to a depth of 80 ft. No quartz was crushed. Nine men were employed. Moanataiari North (Area, 12 acres 2 roods). —A parcel of 15 tons of quartz yielded 1 oz. 5 dwt. Two men were employed. Neiu Alburnia Mine (Area, 54 acres 2 roods). —This mine was taken over in October last by the New Alburnia Gold-mining Company, Limited (an English company), prevjous to which time the old colonial company carried, on operations. The following extracts from the report of Mr. Robert James, the general manager, to the London directors will show the nature of the works, and gives a correct description of the mine : — The property has a splendid reputation. For many years the ground was worked under the old Cornish system of tribute — i.e., a party of miners would take a portion of ground and undertake to pay the company a royalty in the form of a percentage of the.mill proceeds of gold or bullion, the company, as a matter of course, being protected and their interests watched by their own agents. I have spoken to a number of miners who in times past did very well out of their tribute work on Alburnia ground, and they all have at the present time a great opinion of the property, and entertain a very high opinion of its future capabilities. It will be asked, "Is it not possible at the present time to procure men to take up ground under tribute ? " It is not, for many reasons, the most important of which is that the whole of the property has been honeycombed with previous shallow surface-workings, and a tributer would require to expend a considerable sum of money ere reaching a point that would admit of him exploring virgin ground. The reef—one of many traversing the property—which seems to have produced most gold in the period referred to is the one known as Dixon's, although a large quantity of gold seems to have been obtained from the Sons of Freedom, Star of the South, and Success reefs. There is not the slightest doubt but that the property has been a very highly productive one, and the record of its returns rather under than over estimated. In October, upon my taking over the management for the London company, the workings consisted of a shaft 365 ft. in depth. From this shaft four levels were driven ; the three upper levels were practically closed with debris, and the only work being carried on was from the No. 4 or bottom level. Here the ends were being driven east and west —the east drive was in about 200 ft. and the west 170 ft.
65
0.—3
Taking into consideration the fact that the mine above this level was not only choked by debris but practically worked out, there was no other alternative but to sink the shaft deeper, at the same time continuing the ends and sending up a few rises and prospecting stopes from the back of the drive, not only for the purpose of finding payable stone, but for purpose of ventilation. In this work we have been fortunate ; not only have we made the necessary connections for the proper ventilation of the mine, but we have taken out some hundreds of tons of stone of a payable character which has been passed through the mill. The stuff taken from the east and west drivages was dumped into the hoppers at surface, and transported by aerial road to the battery. Much of this stuff was of very low grade, but improved in value as we proceeded ; but having this cheap means of transportation, coupled with the economical advantage of waterpower, the cost of sending it to the stampers was not increased a particle, it being quite as cheap to deposit it at the mill as at the shaft dumps. The work performed at the mine for a considerable period before being purchased by the English company was of a desultory character, possibly from want of working funds, but certainly for the want of a settled policy. The main object of all exploratory work for years past seems to have been the discovery of rich patches which could be worked out quickly, producing phenomenal returns, and resulting in a wild scramble to get shares in order to participate in the general dividend ; then, when the faith and adventurism of the shareholders had become exhausted, at the departure of the patch, another tribute would be let, or the company would undertake to do a little dead-work prior to further explorations. This may have suited the times; it most certainly suited the average shareholders, who throughout the whole mining history of the peninsula have shown a great aversity to providing funds, or, more properly speaking, working capital, for the systematic and thorough exploration of mining ground. We are now thoroughly developing and exploring the property. The contract for the sinking of 100 ft. main shaft commencing from No. 4 level, a depth of 365 ft., was commenced on the 16th November and completed on the last day of February. This work (taking into consideration the fact that we used the shaft continually for the hoisting of dirt for the battery) has been rapidly performed. The dimensions of shaft are 10 ft. 6 in. by 4 ft., and it is securely timbered and divided for the operations of two cages. Upon first taking over the property it was not deemed wise to reopen the old portion of the mine above the bottom level, but subsequent discoveries of small leaders, carrying considerable gold, and tending upwards, led us to attempt the task of opening and securing the upper portion of the mine. This we have succeeded in doing, the advantages accruing through same being of the greatest importance, principally the opening-up of an old winze sunk 110 ft. deep upon the foot-wall of a reef at a point several hundred feet west of No. 4 level. We are now on the eve of the completion of sinking the shaft to a depth of 465 ft., and before cutting chambers, &c, are going to start a drive south to connect with the bottom of this winze and an old level. This work is intended not only for ventilation and communication, but to intersect a reef which in former days, and before the present cheap transportation was possible, was thought too poor or of too low a grade for extraction. Our plant at the present time may be classed as obsolete—that is, as far as the battery and amalgamation tables are concerned ; but the Denny pans and berdans are capable of doing excellent service, their results being very satisfactory. With the plant, old as it is, we have been enabled to give the mine a thoroughly good practicable test —such a test as could not be possibly obtained under any other conditions. We hope in the near future to open up sufficient ore bodies to warrant the erection of a first-class modern plant with all the latest improvements. The low-grade ores of this mine are difficult to treat, the stone being highly mineralised, containing a large percentage of iron-pyrites, with small quantities of copper-pyrites, galena, and zinc-blende. The ores cannot be directly treated with cyanide, but from a number of experimental tests made by Mr. Allen, of the Thames School of Mines, and Mr. Henry Allom, a gentleman who has had a unique experience in the use of cyanide, we have concluded that after the ores have passed completely through the mill and before being exposed to the air the tailings can be successfully treated with potassium-cyanide. Although our ores are low grade, we possess the great advantages of cheap transportation and water-power, and are enabled to work them at an average cost of 3s. 6d. per ton. As a matter of fact, during stoping and general explorations we occasionally find small bunches of rich stone which materially assists the average value of the stone passed through the mill. The general character of the stone is also improving, as will be perceived from the monthly returns. Although our mining plant is not everything that could be desired, it is still equal to doing much more good service. The shaft since the completion of the last contract is now down to a depth of 465 ft., securely timbered throughout, contains a man-way, and is operated by two patent safetycages, which are changed alternately, as, owing to the destructive nature of the water, it becomes necessary to look closely after all steel and iron material. As a matter of fact, since the property was taken over by the London company we have had nothing to face back upon to keep the battery employed but old ground. This has led to the reopening of the old portions of the mine, and thorough ventilation, and before long we shall have several good exits to the surface. It may therefore be said with truth that the future history of the mine will commence with the opening-up of the No. 5 or 465 ft. level. The amount of quartz worked and the yield of gold therefrom was as follows : November, 1896 —235 tons ordinary quartz, 57 oz. 15 dwt. melted gold ; December, 1896 —285 tons ordinary quartz, 100 oz. melted gold ; January, 1897—365 tons ordinary quartz, 144 oz. 2 dwt. melted gold ; February, 1897—215 tons ordinary quartz, 107 oz. melted gold; March, 1897— 304 tons ordinary quartz, 150 oz. 10 dwt. melted gold. The total number of tons worked to end of March was 1,404; and the total return of bullion 559 oz. 7 dwt..value £1,482 ss. 6d. It will be seen that the general character and value of the stone has gradually improved. The following are the particulars of the working on reefs: 1896—Driving, 292 ft. east, 180 ft. west; sinking, 49ft. 1897 —Driving, 226 ft.; sinking, 51 ft. This work is exclusive of stoping and all dead-work. Twenty men are employed.

Darwin Mine (Area, 8 acres). —This mine is situated at Punga Flat. There are not less than nine reefs and leaders in the ground, varying from a few inches to 2 ft. in width. The claim has been worked by different parties during the past twenty-eight years, and, as it lies at an altitude of 1,500 ft., it is highly probable that gold will be traced to greater depths in low levels. Twenty loads (30 tons) of quartz were crushed, for 56 oz. 10 dwt. of gold; value, £158 17s. Five men were employed. Prospecting operations have also been carried on in the Alburnia East, Caspian, City of London, Just-in-Time, and European Claims. Grahamstown District. Victoria Mine (Area, 41 acres 3 roods 10 perches).—The chief workings during the year were conducted from the shaft formerly known as the Prince Imperial. The reef averages 1 ft. in thickness, and yields some rich pockets of picked stone; 2,089 tons of quartz was crushed, for 2,174 oz. 3 dwt. of gold, valued at £6,149 17s. 3d. ; tailings sold valued at £18 19s. 6d. ; and for tributers 20 tons for 3oz. 15 dwt., value £10 4s. 3d: total, £6,179 Is. The shaft is furnished with safety-cages, and the winding machinery is driven by a semi-portable engine, Eobey make, 18-horse power. Forty-two men were employed. Cardigan Mine (Area, 64 acres 2 roods). —Prospecting work was carried on from the Saxon shaft, and a parcel of 16 tons 10 cwt. of quartz yielded 3 oz. 5 dwt. The company is now sinking a shaft opposite the Thames Star office. Six men were employed. Drainage. Drainage of the deep levels is carried on by the Thames Drainage Board, the Big Pump shaft being used. The working manager reports that the consumption of coal for the year ending 31st December last was 2,459 tons. The following extracts from the annual statement of accounts show the financial position of the Board, and also the contributions from the different companies assessed:— Receipts. £ s. d.

The chairman said the matter had been gone into from time to time, and it had been found that the figures came out in favour of New Zealand coal. As a matter of fact, only local coal had been used for the past two years, which in itself was sufficient proof. A test was made recently of coal from Westport, Hikurangi, and Ngunguru, with the following result: Westport, 6 tons per day of 24 hours, at 195., £5 14s. ; Hikurangi, 7-J- tons per day of 24 hours, at lis. 9d., £4 Bs. Id.; Ngunguru, 6J tons per day of 24 hours, at 12s. 5d., £4 os. 9d. By this you will perceive that Ngunguru is the cheapest coal for our purposes, and, in addition, it is also the easiest on the fire-bars. Waiotahi District. Waiotahi Mine (Area, 22 acres 3 roods 30 perches).—This mine still continues to be a dividendpaying one. The nature of the work carried on is of the same character and in like manner as has

been the case for the past ten years—driving and stoping on the reefs and leaders between Nos. 1, 2, and 3 levels in the main shaft, and on the large reef between Nos. 1 and 2 levels in the Mary Ann shaft. The mill consists of twenty-one stamps, 6 cwt. each, and five berdans, and is driven by a 16-horse-power steam-engine. Twenty stamps were run for three hundred days, crushing 1,613 tons of quartz. This is the only mill on the Thames driven by steam-power, all the others using water-power. The gold obtained was 2,057 oz. 5 dwt., value £5,606 os. Id., for the company, and 261 tons, for 342 oz. 4 dwt., value £932 95., for tributers. Twenty-one wages-men and four tributers were employed. Nonpareil Mine (Area, 21 acres). —This mine includes the ground formerly known as the Little Maggie, and is now held by an Auckland company. A considerable amount of work has been done in cross-cutting and driving on the reef, but no returns of gold have been made since the company acquired the ground. Eight men were employed. Cambria Mine (Area, 15 acres 2 roods 17 perches).-—This mine was worked by the Cambria Gold-mining Company until December last, when it was disposed of to the Anglo-Continental Gold Syndicate, who will add it to the Moanataiari Mine.

Thereafter they received an offer from the Anglo-Continental Gold Syndicate (Limited) of 7,450 shares fully paid up to £1 in the Moanataiari Gold-mining Company (Limited) for the company's property. The offer was duly considered in your interest, and was accepted on condition that the shares are placed on the Moanataiari colonial register as soon as the scrip can be received from London. When the directors receive the scrip, which will give one share in the Moanataiari for every six held in the Cambria, the property will be handed over, and the shares will be duly allotted. Your directors consider that they have done as well as could be expected, as the operations at the mine involved making calls to work at a greater depth, which requires capital. For the present year 93 tons 10 cwt. of quartz was crushed, for 154 oz. 5 dwt. gold; value, £408 15s. Eight men were employed. West Coast Mine. —The mine is worked by the owner, Mr. John Northey. His operations are chiefly confined to working small veins in the upper portion of the ground. 25 tons of quartz was crushed, for a yield of 17 oz. 10 dwt., valued at £46 7s. 6d. Two men were employed. Fame and Fortune Mine (Area, 71 acres 3 roods 19 perches). —This mine is now the property of the Hauraki Golden Age, an English company. The chief work clone during the year has been driving on and opening up the reefs at four different levels. The Golden Age reef, being a large body, is being cut through in different places to ascertain the width of quartz and value preparatory to the erection of a new battery and aerial tramway from the mine to the mill. The new mill is to consist of forty stamps and two stone-breakers, to be driven by both steam- and water-power. The method of treatment of the tailings after passing over amalgamation copper-plates has not yet been decided on. A parcel of 27 tons was crushed, for 6 oz. 3 dwt.; value, £16 ss. lid. Fifteen men were employed. Prospecting has also been carried on in the New Caledonia, Cumberland, and Cumberland Extended Claims. Waiokaraka District. The Queen of Beauty section of the Thames-Hauraki Goldfields Mine consists of an area of 47 acres. The chief work carried on during the year has been enlarging the shaft to a depth of 425 ft., and in making preparations for the erection of the new machinery and pump. Forty men were employed. The importance of this work towards the development of the reefs at deep levels cannot be overestimated. The plant which is being erected is of a substantial and efficient character, and shows the intention of the owners to provide ample power for drainage of the country to a depth of 2,000 ft. The cost of the undertaking will be great, and the subsidy of £25,000 provided by the Government is being fairly earned, the amount already paid towards the work being £2,593 lis. Id. The advantages from the drainage of this portion of the field as the sinking progresses will be first realised by the May Queen Company, which, as soon as the shaft is completed to a depth of 650 ft., will be enabled to open a new level and work a large block of ground under the rich quartz taken out at the No. 4 level. The following description of the works and new machinery, furnished by Mr. H. A. Gordon, who is supervising, will be of interest as showing the requirements for the construction of an extensive plant suitable for deep mining and drainage : — This company has widened the Queen of Beauty shaft to a depth of 426 ft., the dimensions of the shaft being 17 ft. 6 in. long by 8 ft. 6 in. in the clear. It is timbered with frames of 16 in. by 12 in. heart of kauri timber. These frames are placed 4 ft. apart, with upright studdles in the corners of 16 in. square, and lagged behind the frames with 2 in. planking. At 300 ft. the shaft is widened out to 17 ft. 6 in. by 16 ft. 6 in., to provide for space at the change of lifts, which takes place at every 327 ft. At one end of the shaft there is a division of 8 ft. 6 in. by 4 ft. 6 in. to provide for the winding compartments. A new set of poppet-heads is erected, having caps each capable of 10—C. 3.

bearing a working transverse strain of over 400 tons. The legs are about 2 ft. 6 in. square at the bottom, having a slight taper up to the top. They are about 90 ft. long, well braced and stayed, and capable of resisting the greatest strain that they can ever be subjected to, even if a whole column of pipes were slung from the top. The foundations for the pumping-engines and pump quadrants are all in one solid block, made of concrete, of one part of best Portland cement to five parts of broken metal and sand, enough sand being used to fill up all the interstices. The portion the engines are fitted upon is 61ft. 6 in. wide by 67 ft. 2 in. long and 20 ft. in depth; and the foundations for the pump quadrants are 12 ft. by 12 ft. and 12 ft. deep on each side of the shaft, with a wall of concrete joining these two blocks 4 ft. thick. The whole of the foundations are built in a homogeneous mass, and form one block, having a weight of about 5,891 tons. Portions of the foundations are on the solid rock, and where this could not be obtained rows of piles were driven into the ground until the rock was reached, and the concrete put on the top of them. The foundations for the winding-engine and capstan-engine are all in one block, only the winding-engine foundation stands at a level of 4 ft. above the level of the foundation of the capstanengine. The foundations are 5 ft. long by 26 ft. wide and 12 ft. deep on the place where the wind-ing-engine is fixed, and 8 ft. deep where the capstan-engine is placed. This foundation is made of one block of homogeneous concrete, of the same strength as that already mentioned for the foundations of the pumping-engine, the weight of this block being about 971 tons. A concrete foundation of 16 ft. square and about 4 ft. in thickness was made to commence to build the brickwork. The stack is built in a square shape with bricks, and is 103 ft. 6 in. high, being 7 ft. 3 in. square at the top. A large flue is built of brick to connect the different boiler-flues with the stack. A concrete foundation is made for building in ten boilers 99 ft. 6 in. long by 40 ft. wide. All the flues, whereever subjected to great heat, are built of firebrick, and all the flues from the boilers connect with a main flue, which is constructed at the back end of the boilers, large enough for a man to pass through to clear them out at any time. The pumping-engine is to consist of one pair of horizontal compound condensing engines, the high-pressure cylinder being 31 in. and the low-pressure 59 in. in diameter, both with 5 ft. stroke. Each cylinder is steam jacketed, and placed side by side with receiver and auxiliary steam-valve on low-pressure cylinder, and working on the cranks at right angles. Steam-chests are fitted at each end of both high- and low-pressure cylinders with variable expansion-valves worked direct from the crank-shaft and variable by hand, the range of cut-off being from nothing to five-eighths stroke. All glands and bushes are lined with gun-metal, and the glands and cylinder covers are polished outside. The piston-rods are carried through each cover. The cylinders and steam-chests are coated with asbestos, slag wool, and timber, and covered with planished steel plate secured by polished brass belts 2 in. wide, fixed with set screws. The cylinders are drained by a cock at each end, and the steam-chests are drained by cocks placed in suitable position. Each end of the cylinders is fitted with 2 in. spring relief-valve; also a side-feed lubricator, with a capacity of one pint (1 lb.), is fitted to each cylinder. The steam-receiver is placed between the cylinders, steam-jacketed and lagged with asbestos, slag wool, and timber, covered with sheet steel. This is drained by a cock connected to the same way-shaft as cylinder cocks. The jacket is also drained by an ejector. The throttle-valve is of double-beat type, with seatings of gun-metal. The governor is of the highspeed Porter type, controlling the supply of steam according to requirement, maintaining regularity of movement, and set so that the speed of the engine will reach thirty-four revolutions per minute. The piston bodies are made of cast iron, 8 in. deep in centre and 7Jin. at the edges. They are attached to the rods by recessed nuts screwed upon the rods, and are fitted with steel coils and castiron junk-rings. The piston-rods are of forged steel, and of sufficient length to project through both ends of cylinders, and are secured to front and hind cross-heads by steel cotters, having a solid collar forged on for attachment to piston, to which it is screwed, the diameter of the pistonrod being 5 in. The cross-head and gudgeon are made of hammered steel, bored taper to receive the piston-rod, to which it is cottered. The cross-head has cast-iron slipper-blocks, each 21 in. long by 6 in. wide. The gudgeon is of forged steel, 6-J in. diameter by 8 in. long in the journal, shrunk into cross-head, and fitted with steel key. The cross-head for tail-slide is also of steel, into which the piston-rod is fitted. The cross-head also receives the links actuating the air-pump and circulating pump levers. The connecting-rods are of hammered steel, polished all over; the crosshead end is made adjustable with gibs and cotters, fitted with heavy gun-metal steps ; the crank-pin end is worked from the solid, fitted with gun-metal steps, adjusted by means of cotters and set-screws. The length of each connecting-rod is 13 ft. 6 in. centre to centre, being siin. diameter at cross-head end, 6 in. diameter at crank-pin, tapering to 7 \ in. diameter in the middle. Large gun-metal lubricators are fitted at each end of the rod. The crank-pin bearing is diameter and 9 in. long. The crank-shaft is made of the best hammered steel, turned and key-grooved if necessary, its bearings being 13^-in. diameter and 20 in. long. The length between centre of engine is 16 ft., and the shaft is swelled in the centre to 16 in. diameter, on which the fly-wheel and spur-pinion for driving pump gearing are placed. The cranks are also made of best hammered steel, machined and polished all over, and are also keyed on at right angles on each end of the shaft. The crank-pins are 7 J in. diameter and 9 in. long; these are forced into the crank by hydraulic pressure, and afterwards riveted over. The eccentrics for working the valve motion are made of cast iron in halves, with adjustable rods of brass, and made with clips to join the eccentric rod with butt ends. All the valve motion rods and spindles are made of the best hammered steel, and all the bearings are of gun-metal made adjustable. The fly-wheel is 15 ft. in diameter, 20 in. wide on the face, and turned on rim and edges. The two halves are bolted together, and further secured by wrought-iron hoops shrunk on the bosses, the weight of the fly-wheel being about 20 tons. This wheel can be used for belt-driving if required. It is also fitted with a spur-ring for barring purposes, and a barring-engine with a pair of cylinders 10 in. diameter is to be fitted on to plates, and bolted to foundations, with all necessary pipes, lubricators, and drain-cocks. A spur-pinion is fitted on the
69
C—3
crank-shaft for driving the spur-wheel on the pump-shaft. This pinion is made in two halves, and turned together, having twenty teeth, Bin. pitch and 21 in. wide, shrouded up to pitch-line. The engine-bed is made of heavy cast-iron box girder section, having a depth of 18 in. and a width at the narrowest point on the top of 10-J-in., and 15 in. over beading at bottom, Each bed is made in two pieces, firmly bolted and joggled together. The beds are planed all over on the bottom, and also faced where the cylinder slide-bars and pedestals rest. The air-pump is worked from the tail-slide of the high-pressure cylinder by means of steel levers, shafts, and links, the shafts to oscillate in gun-metal bearings, and the ends of the links are fitted with gun-metal bushes. The air-pump body is made of cast iron lined with gun-metal, having the pump-bucket also made of same material. The air-pump rod is made of Muntz metal, having the foot-valves and searings of brass. The bucket-valve and delivery-valve are made of indiarubber. The hot well at the top of the air-pump is covered over to prevent water flowing into the foundations. The circulating pump is worked from the tail-slide of the low-pressure engine in a similar manner to the air-pump, and is double acting, of sufficient size to maintain a constant supply of water to the condenser. All the valves, seatings, plunger, and liner for pump-barrel are of gun-metal. The condenser is of the surface-condensing type, having a cooling surface of 2,450 square feet, with tubes of lin. in diameter outside and 19 w.g. thick, secured at both ends with screwed brass glands and nipples. The tube plates are of brass If in. thick, and are stayed together by five gun-metal stays. The condenser body is of steel plates and angles, and the joints lapped and on top. A single-acting feed-pump, with gun-metal seatings and valves, is provided to supply feed-water for seven boilers, and is worked from the same levers as the circulating pumps. There are ten boilers, of the Lancashire double-Sued type, each 7 ft. in diameter and 30 ft. long, constructed so as to carry a daily working pressure of 120 lb. to the square inch. The plates for the shell are of Siemens-Martin steel, sin. thick; the longitudinal seams are butt-jointed, with inside and outside cover-plates. The circular seams are lap-jointed, and zigzag riveted. All the rivets are A§ in. diameter, fin. holes, 1-J-f in. pitch. The circular seams have a lap of 3f in., and the covering-plates for longitudinal seams are 8 in. wide and fin. thick. All the holes in the boiler are drilled, and plates bent and ready to put into position on landing in the colony, and also all the plates planed on edges; each belt of plating or ring of the shell is all in one plate. These were sent out to the colony in pieces, and the boilers are now being riveted by Messrs. Price Brothers at the Thames. The flues are 2 ft. 9 in. internal diameter, except the last two rings of plates at the back. The last plate is 2 ft. 3 in. in diameter, and the second to that tapers from 2 ft. 9 in. to 2 ft. 3 in. All flue-plates are of steel, -J-in. thick, welded longitudinally, and flanged outwards at the ends; each length is connected by a solid welded ring, which takes all the rivets out of the action of the fire. The ends of the boilers are also made of Siemens-Martin steel, in one plate, i-J in. thick. The front plate is attached to the shell by an angle-iron ring 4-Jin. by 44; in. by and the back plate is flanged to meet the boiler. The ends are stayed by means of strong gusset-plates fastened by double angles to shell and end plates. There are five gussets above the flue and two below. These stays are not brought too close to the furnaces, sufficient space being allowed for expansion. The ends are further stayed by two longitudinal stays, 2 in. diameter, extending from end to end of the boiler, and securely fastened by nuts and washers inside and outside of end plates. Each boiler has a dome on its third ring from front 3 ft. in diameter and 3 ft. high, solid welded, and flanged to meet the boiler shell; the top is fitted with an angle-iron ring 3-J in. by 3-J- in. by fin. The top plate is 1J in. thick, on which the shut-off and dead-weight safety-valves are placed. The hole in the boiler shell to which this dome is riveted is Ift. 10 in. diameter, and has a strengthening ring added in the boiler under the dome. A strong steel man-hole is riveted on to the top of the boiler on the second ring from the back, and has a strengthening ring underneath, fitted with covered dogs and bolts. On the top of each dome there is a steam stop-valve, 6 in. diameter, with gun-metal spindle, valve, and seating; also a dead-weight safety-valve, 3 in. diameter, which is used when steam is at 120 lb. pressure. Each boiler is fitted with two check feed-valves, 2-J in. diameter, with iron body and gun-metal working-parts. A horizontal internal pipe projecting for 12 ft. into boiler; also one gun-metal blow-off cock, 2-J-in. diameter, with compound glands, and one taper connecting-pipe fitted to cast-steel mountings on underside of boiler shell. Two sets of asbestos packed glass gauge-cocks, with fin. glass; flanges being 4J in. diameter, fixed on steel bases. One brass pointer to show working-level of water in boiler. One pressure-gauge, with 9 in. dial, indicating up to 2501b. per square inch, fitted with syphon and tap, and one fusible plug in each flue. There is also sent along with each boiler one of Howl's patent hot-blast forced-draught furnaces, which is to be fitted to each flue, having a grate 8 ft. long. These, however, are not at present fixed on to the boilers. One of these will be fitted on to see what difference, if any, it will make in regard to its economy in using fuel before fitting them on to each boiler. Three of these boilers are now fitted together, and are in course of being built in, while the whole of the plates for the boilers are landed at the Thames, and are being fitted up at Price Brothers' foundry as quickly as possible. With reference to the whole of the machinery in connection with this pumping plant, only some of it has yet arrived, but the greater portion is now in course of transit from England. The second motion shaft is to be of the best hammered steel turned all over; the bearings are 20 in. diameter and 30 in. long, three of these being in the shaft. The shaft is swelled in the centre to 22 in. to receive the spur-wheel. The weight of this shaft with solid crank is 18 tons. The spur-wheel, which fits on to the shaft, has seventy-two teeth 8 in. pitch and 21 in. wide shrouded up to pitch-line. There are to be two sets of pumps in the shaft, each plunger or draw-lift being 25 in. in diameter, having a single rising main 20 in. in diameter; these are fitted so that a change of lifts will occur at every 327 ft. of vertical height. All rods and connections are of sufficient strength to admit of sets of pumps being added to lift 2,000 gallons of water trcm a depth of 2,000 ft. The draw-lift pumps are of the open-bucket type, 25 in. in diameter, and suitable ior a stroke of 6 ft. The barrels are made of cast iron, truly bored, and fitted with strong suction-valve boxes of
C— 3
70
cast iron, having large man-holes for inspection of suction-valves. The suction-valves are so arranged that they may be fished and withdrawn through the rising main if necessary. At the top of the working barrels are strong iron boxes, or what may be termed door-pieces, having man-holes for convenience in inspecting and removing the pump-buckets. All the flanges are strongly ribbed, and the man - hole mouthpieces have wrought - iron hoops shrunk around the flanges. The suction-valves are made of gun-metal of double-beat type; the seatings are fitted into tapered seats in valve-boxes. The valve-wings are set to give the valves a screw lift. The pump-buckets are made of gun-metal, fitted with delivery-valves of double-beat type, having a screw lift. Each bucket is to be packed with three gun-metal packing-rings, turned larger in diameter than the bore of the pump-barrel, cut on circumference, and sprung into place, stop-pieces being fitted on to each ring. The plunger-pumps are 25 in. in diameter, with a stroke of 6 ft., the pump bodies being of cast-iron, and strongly ribbed at all flanges, with hoops shrunk on all openings, and fitted with strong sludge-doors and -cocks. Strong brackets are cast on pump body for attachment to supporting girders. The plungers are of hard close-grained cast iron, truly turned and solid. Automatic shifting-valves are placed on the top of the plunger-pump barrels. Cast-iron air-vessels are also fitted between the delivery-valve boxes and the rising main, to withstand the same head- and testpressure as the pumps. The air-vessels have long narrow necks, and are provided with an approved arrangement for replenishing and maintaining the air in the vessels. Each pair of plunger-pumps delivers into one rising main of 20 in. internal diameter, made of cast iron of sufficient strength to withstand the pressure they have to sustain, each pipe being in 12 ft. lengths. They are all coated with Dr. Angus Smith's preparation, and are tested to withstand a hydraulic pressure of 2501b. per square inch. The branches from the delivery-valve boxes of the plunger-pumps are connected together and to the rising main by strong cast-iron pipes, upon which the air-vessels are seated. These branch pipes are sufficiently strong to withstand the pressure due to a water-head of 327 ft. The spear-rods are on the road out from England, made of iron, 10 in. in diameter ; but it is questionable whether these will be used. The company here prefer to use spear-rods made of kauri, having strap-bolts, brackets, and connections, which will be constructed here. The top of each spear-rod will be fitted with gun-metal steps, skeleton straps, gibs, and cotters, with all necessary plates and bolts for connecting the bearings to the top spear-rods. These rods will be made of such a strength to resist a strain sufficient to raise 2,000 gallons of water from a depth of 2,000 ft. Wrought-iron girders are being constructed to support the pumps in shaft. This was not included first in the contract, but the engineer who drew the detailed plan at Home considered that these would be preferable to beams made of timber, and would give more room in the shaft. A handpower travelling-crane is to be fixed on supporting columns in engine-house for the purpose of erecting and overhauling the different parts of the engine. This crane is sufficiently strong to lift and readily handle a load of 12 tons, and is placed on timber gantries supported on cast-iron columns, being 30 ft. from centre to centre of longitudinal rails, fixed at a height suitable for a lift of 18 ft. clear from the engine-house floor, the gantries running transversely across the enginehouse from wall to wall, and the crane is arranged for hoisting and travelling longitudinally and transversly ; all motion to be capable of being put into gear independently or at the same time, and actuated from platform on the main crane girder. The pumping-engine is to be utilised to drive a dynamo to supply power to work a forty-stamp battery, having an electric motor in the stamp-mill. The dynamo to be series wound, and to develop 55,000 watts at a speed of 700 revolutions per minute, the electro-motive force of the dynamo being from 300 to 500 volts, according to the distance through which the power has to be transmitted to the milling plant. The magnet limbs of the dynamo are to be either made of soft wrought iron or a special quality of cast steel, as made by Edgar Allen and Co., Sheffield. The armature is built up of soft wrought-iron plates insulated from one another by paper or varnish, and mounted on a strong gun-metal hub, which is securely attached by keys to the shaft, there being no bolts through the armature core-plates, but they are held together by end pressure. The wire has a conductivity of 98 per cent, of pure copper, and insulated with double cotton, well protected from all contact with the body of machine. There are six brushes mounted on a brush-holder capable of rotating round the bearing-end, with suitable means of fixing it in position when the right lead is obtained— i.e., whether the pole-pieces are at each side of the armature or at the top and bottom the brushes will touch the commutator in a horizontal line. The commutator is to be constructed so as to have a high conductivity of solid-drawn copper bars, insulated with mica and fixed in the commutator brush. The spindle is of the best mild Siemens-Martin steel, with provision made for securing the armature hub. All the bearings are of cast iron and bushed with phospor-bronze, with all necessary oil-cups and means of lubrication. The bed-plate is made of strong cast iron, and extended to take a third bearing, with suitable attachments for the belt striking gear, complete with side-rails, tightening-screws, &c. The motor is in all respects similar in design to the dynamo, with the exception that there is no loose pulley and striking-gear, and is capable of giving out 68 brake horse-power at the motor-shaft with 55,000 watts at the terminals at a speed of 650 revolutions per minute. Dynamo and motor are fitted with eye-bolts screwed into magnet yoke for lifting purposes. The switchboard is constructed of ample strength, and contains volt and ammeter, the ammeter being provided with a cut-out plug of negligible resistance. All cables are of sufficient strength for carrying the current at more than 1,000 amperes per square inch density. The countershaft for dynamo is driven from the main pumping-engines when the engines are working below their power, and is arranged so that the dynamo can be stopped for a short period when required, leaving the whole line of shafting and straps running. An electric-lighting plant is provided, having a separate engine of 10 brake horse-power when working at 100 lb. per square inch. This engine drives a dynamo, compound wound, of sufficient capacity for 2,000 candle-power and 75 16-candle-power, the speed of the dynamo being from 1,250 to 1,350 revolutions per minute. It is provided with one spare armature and six spare brushes.

A separate compound engine is provided for air-compressor and rock-drills, having cylinders of 16 in. and 31 in. respectively, with a 36 in. stroke, the air-compressor being of the coupled compound type, the air-cylinders being also compounded, having 31 in. and 19Jin. diameter respectively. A water-jacket is fixed around the air-cylinders, the water being admitted by a perforated pipe in the bottom, and overflowing at the top. The compressed air is delivered into an intermediate cooler, made of steel, of sufficient strength to withstand a working-pressure of 60 lb. per square inch, having an air-space of 75 cubic feet, and a cooling surface of about 140 square feet. The small air-cylinder compresses the air from 901b. to 1001b. per square inch. The inlet-valves are connected to the cooler by an ample-sized pipe. Both air-cylinders have large lubricators and all necessary lubricating arrangements for the valves. The air is delivered into a receiver having a capacity of 300 cubic feet; it is constructed of steel, and tested to 170 lb. pressure to the square inch, and fitted with safety-valve, drain, pressure-gauge, manhole-door, and cover, and attachment for air-pipe from air-cylinder. An independent surface condenser is supplied, having a cooling surface of 500 square feet; the tubes are -§ in. in diameter, made of brass, and fixed by means of screwed glands and nipples, all parts being sufficiently strong to withstand a pressure of 50 ft. head of water. The plant is capable of working twelve sets of drills, with which it is provided. These drills are also supplied with twelve stretcher-bars; twelve universal clamps; twelve 50ft. lengths of flexible hose, lapped with tarred marline, and brass fittings ; twelve G.M. main cocks, with couplings ; and one set of drill-sharpening tools. The whole of the work is progressing as fast as it is possible to get it done. The manager, Mr. T. A. Dunlop, is indefatigable in his exertions to push on the work, and Mr. Hughes, the engineer, who was sent out by the contractors, is always on the ground superintending the operations, and getting out detail designs for the different arrangements of the machinery. May Queen Mine (Area, 73 acres 1 rood 18 perches).—The mine was early in the year disposed of to the Anglo-Continental Syndicate, who again disposed of it to the May Queen Hauraki, Limited (an English company), under which ownership it is now held and worked. The following extracts from the account of the annual meeting of the May Queen Gold-mining Company (Limited) gives particulars of the transaction, &c. : — Receipts. jg Si ,j.

Your directors thereafter, on the 9th April, 1896, received a proposal from Mr. Moss Davis to place the property locally, through the AngloContinental Gold Syndicate (Limited). The following offer from the latter was received through Mr. Davis: " Anglo- Continental Gold Syndicate (Limited), Bank of New Zealand Chambers, Auckland, sth June, 1896.—The Directors, May Queen Gold-mining Company (Limited). —Gentlemen, —On behalf of the Anglo-Continental Gold Syndicate (Limited) I agree to purchase your company's property on the following terms : (a.) The purchasing company to have a capital of £200,000, in 200,000 shares, of £1 each, (b.) Your company to receive 82,000 fully-paid-up shares, (c.) A working capital of £30,000 to be provided by the purchasing company, and paid in manner following: (1.) £7,500 cash down, and the balance as required. (2.) The titles to the property to be held in escrow by the Bank of New Zealand, Auckland, until the whole of the working capital be provided by the purchasing company. Your shares as vendors to be pooled pro rata with the English shares for nine months at a price of not less than £1 per share. I guarantee the due performance of the above conditions, and the completion of the purchase on the above terms.—Henry A. Gordon, General Manager." Mr. Gordon's offer on behalf of the AngloContinental Gold Syndicate (Limited) was accepted, as under: " Office May Queen Gold-mining Company (Limited), Auckland, sth June, 1896.—Dear Sir, —I have the honour to acknowledge the receipt of your letter of this day's date, containing an offer for this company's property, and to state that the same was laid before the Board of Directors at a meeting specially convened for its consideration. In reply, lam directed to inform you that the terms set out in your letter have been accepted by the Board." The work carried on prior to the new company taking over the mine was confined to working on leaders in the Saxon section of the ground, and after the 7th June work was still continued on the reefs in this section. 638 tons of quartz was crushed, for a yield of 578 oz. 12 dwt. of gold ; value, £1,533 ss. 6d. The following is a report of the work done since the new company took over the mine :— This company purchased the whole of the property of the May Queen Company in June, 1896, and since then it has been carrying on prospecting operations on the portion of the old workings above the drainage level. The May Queen Company, prior to the sale of the property, had stoped out all the reefs known to be payable for working down to the level at which drainage is effected.— namely, the No. 6 level at the Saxon shaft and No. 4 level in the May Queen shaft, both of these being actually on the same level. The mine cannot be opened out at deeper levels until such time as
C— 3
72
the Thames-Hauraki Company's new pumping machinery is erected, and the Queen of Beauty shaft enlarged to a depth of 650 ft. As soon as this is done the mine will be opened up, and from the returns got from the reefs by the old company at the present levels, which proved to be the richest ones got from the mine, there is every reason to believe that rich ore will be got when once the next levels are constructed—at least, the evidence so far is in favour of this —and that it is likely to prove in the future one of the best mines on the Thames Goldfield. In carrying on prospecting operations on the present levels a cross-cut was constructed from the No. 6 level in the Saxon section for a distance of 500 ft., and two new reefs were cut, each varying from 12 in. to 15 in. in thickness. These were cut in the Cardigan ground, near the boundary of the May Queen-Hauraki property on the No. 4 level, in the Saxon section, but the yield at this level in the Cardigan was only about 10 dwt. of gold per ton. The No. 2 reef, in the May Queen ground, which was cut about 300 ft. from the Cardigan boundary, showed fair specimen stone; and, after driving on it to the north-eastwards for about 70 ft., twenty-seven loads of quartz was crushed at the battery, which yielded 46 oz. gold, being equal to an average of 1 oz. 14 dwt. per load. The company are now satisfied with the prospects, and have commenced to construct an uprise to connect with the No. 4 level, which was driven on the boundary of the Cardigan ground in order to obtain ventilation. Stoping cannot be commenced until this is done, as the air is very sluggish at the present time, and has to be forced into the uprise to admit of work being carried on ; but when once the connection is made it will give good ventilation in this portion of the mine to enable stoping operations to be continued. The May Queen shaft is being enlarged to 12 ft. by 5 ft. in the clear, to give two winding compartments and ladder-way. This is completed to a depth of 270 ft., leaving about 250 ft. yet to enlarge before it reaches No. 4 level. As soon as the Thames-Hauraki Company commence pumping operations, and lower the level of the water in the ground, this shaft will be sunk to a corresponding depth to the Queen of Beauty shaft as fast as the level of the water admits. Prospecting has steadily been carried on in the St. Hippo and Lone Hand sections of the property, but so far no reefs have been met with containing ore considered payable for working. During the year ending the 7th June last, which is the yearly return for the present company, 346 loads of quartz has been crushed from different leaders and reefs met with in carrying on the development works, which yielded 526 oz. gold, representing a value of £1,411 19s. 4d., while the average number of men employed in carrying on development works for the same period has been thirty-six. St. Hippo Mine (Area, 75 acres). —This mine has also been purchased by the May QueenHauraki (Limited), and important works are about to be commenced in sinking a shaft to prove the ground at Collarbone Creek at a depth hitherto impossible without capital. Lone Hand (Area, 27 acres 3 roods 35 perches).—This mine, which is situated chiefly in the Karaka Creek, but adjoins the St. Hippo, has been purchased by the May Queen-Hauraki (Limited), and important works will soon be commenced. A small party of tributers working on the surface obtained 2 oz. 15 dwt. of gold from a parcel of 2 tons'of quartz, valued at £6 lis. 3d. Block XXVII. District. Deep Sinker (section of Thames-Hauraki Mine). —This consists of an area of 93 acres, lying between the Township of Shortland and the Una Hill. The land was formerly prospected by a tunnel driven from Karaka Creek in a southerly direction. It was found that almost the whole of the ground through which the drive had been carried was of a late formation, the solid rock being underneath, as it was occasionally found in the floor of the drive. It was therefore imperative, in order to prospect the ground, to sink a shaft. The company decided to commence operations in the lowest portion of the land, near Eolleston Street. Twelve men were employed. Mr. T. A. Dunlop, the manager, gives the following account of the work already done : — This ground is virgin, and situated on Block XXVII., part of the Thames Goldfield, and adjoining the Queen of Beauty on its southern boundary, and has hitherto not been prospected, principally on account of its large alluvial-drift formation. The shaft now being sunk has reached a depth of 230 ft., and its dimension 12 ft. by 8 ft., divided into three compartments, two winding and one ladder and pumping. AlO in. plunger and draw-lift pump has been fixed in position. The first 110 ft. of this shaft was driven through the above-mentioned drift. We are now sinking through a hard diorite formation. It is intended to go to a depth of 300 ft. to 400 ft. before opening out, unless we meet something good before attaining that depth. This property is on the line of several well-known reefs, such as Pride of Karaka, Occidental, Oriental, Silver King, Eose, and Consolidated, all well known to be gold-bearing. Shortland District. Deep Level Consolidated (section of the Thames-Hauraki Goldfields property) (Area, 110 acres) is situated to the southward of the Deep Sinker section, and lies chiefly in the Suburb of Parawai. The characteristics of the surface formation are in a great measure similar to those of the Deep Sinker. An adit-level has been driven towards the rising ground from a point not far distant from Hogg's Corner. Six men were employed. Mr. Dunlop gives the following description of the work done :— This adit tunnel has been driven for the purpose of prospecting. The whole distance has been driven through a volcanic-mud formation, and we have now reached a point in a line with what is known as the Moanataiari Slide or Fault, and is similar in appearance to the Moanataiari. Our intention is to pick up the solid country behind this slide formation on the eastern side, with a view to getting its underlie so as to guide us in locating our principal shaft for pumping and winding. This mine is situated on the goldfield, which has hitherto not been prospected,

Karaka District. Karaka Mines Mine (Area, 84 acres 3 roods 20 perches). —The land comprises that portion of the field lying between Collarbone Creek and Karaka Creek formerly known as the Prosperity and Little Nell Claims. The claim was protected during the greater portion of the year, but since the beginning of 1897 operations have been commenced by the Austinfriars' Syndicate, of London, and the old low level, near the Karaka Creek, cleared for 460 ft., and a drive on the reef, which is 4 ft. in thickness, put in 50 ft. Five men were employed. Claremont Mine (Area, 3 roods 13 perches).—This mine is owned and worked by Mr. George Bryant. The workings are on the north side of the Karaka Creek, and on a line of flinties. Several small reefs and veins run across the belt of flinties at right angles, and it is at and near these junctions where the gold is retained. Specimens of rich quartz are found where the flinty is severed by the quartz vein, showing that apparently the flinty vein is of the oldest formation, in that the fissure filled by the quartz must have been formed subsequent to the formation of the flinty vein. A parcel of 521 lb. of quartz was crushed, for 402 oz. 6 dwt. ; value, £1,126 Bs. 9d. One man was employed. May Queen Extended Mine (Area, 47 acres). —The work carried on during the year in this mine was mostly of a prospecting nature. The low level worked through the Lone Hand and Adelaide ground has been driven in the May Queen Extended ground about 200 ft., making from the mouth of the tunnel 2,200 ft. A cross-cut in the Onehunga section has been put in about 20 ft., and a drive 120 ft. on a reef averaging 2 ft. wide. From a large 18 ft. reef in the creek 81 tons was crushed, for 13 oz. 17 dwt. gold ; value, £37 7s. lid. A drive is now being put in on a 5 ft. reef in the Hokianga section. The company has purchased Bull's battery of twenty-three stamps and thirteen berdans. The 81 tons from the Big Eeef is all that has been crushed for the company, the battery being mostly employed in crushing for other mines. Four wages-men were employed. The New Hauraki, Only Chance, and other claims have been taken up in this district, and more or less prospecting done. Adelaide Mine (Area 21 acres 3 roods). —This mine is situated on the western slope of the Una Hill. The shaft has been sunk to a depth of 410 ft., and a level driven on the reef. A winze was sunk from the adit to the low level. Portions of the reef were stoped out, and a cross-reef also worked on. A parcel of 81 tons of quartz was crushed, for a yield of 63 oz. 17 dwt. ; value, £187 16s. 6d : and a small party of tributers crushed 25 tons, for 14 oz. 19 dwt. ; value, £43 lis. Twelve wages-men and four tributers were employed. The Thames Claim, of 51 acres, consisting of portion of the Una Hill, has again been taken up, but very little work has yet been done. Gloucester Mine (Area, 87 acres). —This mine is situated in the Upper Karaka, and includes the ground formerly known as the Lucky Hit. Prospecting has been carried on during the latter three months of the year, and a commencement has now been made to sink a shaft 12 ft. by 5 ft. in the clear, for the purpose of testing at a low level the No. 2 and Good Fortune reefs, from which good returns were formerly obtained in the surface levels. Eight men were employed. Prospecting work has also been carried on in the European, Duplex, Lincoln, Bell Eock, Manchester, Mclsaacs, and Young Australia, all situated in the Upper Karaka. Little Willie Claim. —A parcel of specimens was crushed, for 20 oz. 13 dwt. of gold; value, £57 16s. sd. Two men were employed. Una Hill and Te Papa District. Occidental Mine (Area, 59 acres). —This mine now includes the old North Star ground. The chief workings were conducted from the adit known as the Una low-level tunnel, and driving was done on the Hague Smith reef, from which small parcels of gold were obtained. The workings in the North Star section are, however, the best for turning out payable quartz. It is the intention to continue a low level from the adit, to prospect the reefs in this district at a greater depth than has yet been attained. A parcel of 119 tons of quartz yielded 239 oz. 2 dwt.; value, £645 lis. sd. Seven men were employed. Fortuna Mine (Area, 61 acres). —This mine has not been vigorously worked. A crushing of 28 tons yielded 9oz. 8 dwt.; value, £25 7s. Bd. Four men were employed. Homeivard Bound Claim. —A crushing of 10tons 10cwt. of quartz yielded 6oz. of gold; value, £16 2s. One man was employed. Hape Greek. Anchor Mine. —This claim was granted to Mr. Adolph Kohn in the latter end of 1895, and the ground for a time protected; but latterly a large staff of miners have been employed in prospecting and reopening some of the older workings. The following extract from the New Zealand Herald gives a very correct description of the work carried on : — " This mining property, which is situated on the left-hand spur of the Hape Creek, just above the Old Consols Mine, and comprising an area of 96 acres 2 roods, is being developed most vigorously by an English syndicate known as the Hauraki (Auckland) Goldfields Syndicate (Limited). Operations were commenced at the latter end of October, since which date the syndicate have not only reopened and repaired no less than five different levels for. a total length of several thousands of feet, and commenced operations in each of them, but also erected a four-stamp battery, with three berdans, for the purpose of practically testing the various lodes that exist in the property. At preseut a staff of thirty miners is employed. So far the prospects met with have been of a very encouraging character, quite good enough to warrant the expenditure being incurred. Several reefs that have in past years and at higher levels yielded excellent returns of gold trend through the whole length of the property. The works now in progress will eventually test these same bodies at a greater depth below the surface. One of these
74
a—3
reefs, known as the Jupiter, is a large body quite 40 ft. in thickness where cut through in the Golden Cable low level, the lowest level now in progress. A contract for driving 100 ft. on the hanging-wall side of this large body is now proceeding at the level mentioned, and a contract is also in course of fulfilment for its intersection at another level about 100 ft. higher —the Golden Anchor level. At each of these points a most favourable class of sandstone country is being entered upon. At the Stephenson level two reefs are being operated upon, from one of which, averaging about 15 in. in thickness, a trial crushing is now being made at the syndicate's battery, with every prospect of its proving payable. In fact, both driving and stoping is being carried on upon this reef and colours of gold are seen pretty freely in the quartz coming to hand. A junction of this reef and what is known as Prescott's leader is expected shortly to be met with, and, as both bodies are gold-bearing, it is anticipated good results will follow. The other reef being operated upon at Stephenson's level averages about 2ft. in thickness, in which colours of gold have also been seen; bnt the ore is scarcely payable as yet. Further development of this body, however, is expected to result remuneratively. At Prescott's level a leader bearing the same name, which averages about 4in. in thickness, is being opened up. This leader has proved to be a good one in the past, and is now yielding a class of ore worth about 2 oz. per ton. Besides the works already mentioned, two or three other prospecting works are also in progress, in one of which (at the Weymouth level) a nice-looking 4 in. leader has recently been intersected, and strong colours of gold seen in it. The present scheme of development will suffice for amply testing the property." The battery has been employed in crushing small parcels from the different reefs. About 150 tons have been put through, but the result is not yet given ; another parcel of 21 tons yielded 2 oz. of gold. Twenty-four men on the average were employed. Mascotte Limerick Mine (Area, 200 acres). —The land is situated at Upper Hape Creek, and is on the line of reefs worked lower down the creek. There are two reefs, one 3 ft. and the other lft. 6 in. in width, besides small leaders. The mine is under offer to the Thames Exploration Syndicate, which has recently employed five men, who are engaged in driving and surface prospecting. Prospecting work was also carried on in the Limerick, Kedge, Shotover, and Masonic Claims. Otunui District. Several claims were taken up in this district, but very little work done. Matatoki District. Considerable amount of work was done in prospecting Teddy's Golden Chariot Claim. Kirikiri District. Fleming's Mine, comprising the Horseshoe, Filly, and Chester Claims, of a total area of 214 acres, was held under option by the New Zealand Exploration and other companies. A considerable amount of prospecting was carried on, but it has not yet transpired whether the purchase will be completed or not. No returns of gold have been received from this mine during the year. Puriri District. Hit or Miss Mine (Area, 30 acres.) —This mine is situated some distance up from the main road on the Puriri Creek, and has been worked for several years for small returns of gold. Since the time the present company became the owners a considerable amount has been expended in prospecting, and the old tunnels reopened. No. 1 level is driven 145 ft. on a reef 1 ft. 6 in. in thickness, and No. 2 level 176 ft., on a 2 ft. reef. A low-tunnel cross-cut at a depth of 400 ft. has been driven a distance of 349 ft., but no reef has yet been cut. This property has been worked for some time past by an English syndicate, which holds the option of purchase. Twelve men were employed, Dover Castle Mine (Area, 100 acres.) —This land has been prospected for the past three months, and a trial crushing of 1 ton taken from a reef in No. 1 drive yielded loz. 17 dwt. of gold; value, £4 16s. 2d. Four men were employed. Prospecting work has been carried on in the Empress of India, Amazon, Wandoline, Eclipse, and several other claims in this locality. Puriri Mine (Area, 100 acres). —This land is situated on Puriri Creek. A small reef 3 in. in thickness was driven on 60 ft., and gold occasionally seen in the quartz. A gold-bearing reef 10 in. in thickness was driven on 130 ft. at the top level, and at the new level it was driven on 54 ft., and proved to be gold-bearing throughout. A reef 4 ft. in thickness was discovered on the surface, but gold has not been found in it. The low-level cross-cut was only advanced a few feet, and no quartz has yet been cut. The rock continues to be of a very hard character. Three men were employed. Fair Alice, Apakura, Lion, Central, Dorrit, and several other claims have been taken up and prospected, but no discoveries or results have been ascertained. Day Dawn Mine (Area, 23 acres). —This land is situated near the Puriri to Tairua old track. The claim was formerly known as the Brothers, and was worked for several years by Mr. Peter Dome, and where there is a large quantity of auriferous matter, is being prospected by trenching and driving. The work has lately been carried on by a party who hold an option on behalf of English capitalists. They are prepared to find capital to work the ground and erect a suitable plant on the permanency of the mine being proved. Three men were employed. Neavesville District. A number of claims have been taken up in this locality, but mining operations have been delayed for the greater part of the year, consequent on titles not being settled, it being doubtful how far the boundaries of the Kauri Timber Company extended.

Tairua Biver District. Broken Hill Mine (Area, 340 acres). —A considerable amount of work has been carried out in this mine for the purpose of developing it in a systematic way for future working. The strike of the gold-bearing lode, which is north and south, has been driven on at the level where the original rich find was made a distance of about 500 ft., and large bodies of payable ore have been seen. The country and the nature of the lode at this level is very broken, and in no case have well-defined walls been found ; but this does not in any way interfere with the value of the lode, as quantities of payable ore can be obtained. At a distance of 300 ft. further south from the original rich find, and immediately under the top of the highest hill, very good ore has been met with. Another level, known as the Cutting level, has been started 40 ft. lower down than these workings, and driven a distance of 200 ft. The lode in this level has a very much better appearance, and appears to continue down between well-defined walls, which are expected to continue to the intermediate and low level. The intermediate level driven from the eastern side of the hill is now in 300 ft., and the low level driven from the western side is now in about 400 ft. Those works will prove the character of the reef at this place. The low level is 700 ft. below the top of the hill already mentioned, and will, when in and connected with the other levels, open up the whole of the mine on an extensive scale. A tramway has been erected (self-acting ground) from the upper level to the battery-site, a distance of a quarter of a mile, and excavations have been commenced for the foundations of the battery, which has been ordered from London. The company intends starting with a twenty-head wet-crushing mill, but is carrying on all the work, such as water-races, &c, for a much larger mill. The principal road made by the company is from the mine to the Tairua Eiver landing, and a tramway has been surveyed and levelled, which may eventually be built. All necessary buildings connected with a mine of this kind have been erected, such as assay-room, office, men's quarters, blacksmith's shop, &c. Thirty men were employed. A considerable amount of prospecting was carried on by Mr. Jonathan Seaver in the Broken Hills Extended and the Tairua Special Claims, with a view of obtaining English capital to work the ground. Tairua Proprietary (Area, 116 acres 2 roods).' —The land is situated in the vicinity of the Broken Hills. A considerable amount of prospecting has been done. Fourteen surface drives were put in, and a low level driven 270 ft., in order to cut the reef, which is 2 ft. in width. Six men were employed. Albert Mine (Area, 153 acres). —Upwards of 500 ft. of a level was driven and two reefs cut, the quartz being of a promising character. Eight men were employed. Prospecting has also been carried on in the New Tairua, Tairua Consols, Marguerite, Emerald Mount, Golden Bay, Tairua Big Eeef, and other claims. Ohui District. Harp of Tara (Area, 30 acres). —A considerable amount of prospecting was done, and four reefs cut, varying from 6 in. to 7 ft. in thickness. A prospect of loose gold can be got in three of the reefs, but not in payable quantities. A tunnel is being put in to cut a large body of quartz which outcrops on top of the hill, and from which prospects of gold have been obtained by washing in the dish. Four men were employed. Nil Desperandum Mine (Area, 86 acres).- —There has not been a great deal of work done during the year, and no quartz was crushed. Three men were employed. Prospecting has been carried on in the Maori Dream, Golden Hill, Sea View, and other claims. In the Ohui properties, held by Seaver Brothers, in all some 5,000 ft. of driving has been carried out, and now work has been concentrated upon the properties known as the Maorilander and the Last Chance, as it is thought that these properties will be the means of opening up the field. It is intended to erect a small battery on the Maorilander, and also drive a large low level into the Last Chance, which will thoroughly prospect this property under what is known as the Big Blow. Whangamata District. Flemington Mine (Area, 88 acres 1 rood 29 perches).—Two drives were put in, one 60 ft. and the other 100 ft. A large body of quartz 60 ft. in thickness was discovered, and two smaller reefs, but no payable quartz has yet been found. Four men were employed. In the following mines considerable prospecting was done, and reefs, in some instances containing a little gold, discovered: lolanthe, Herald, Marco Polo, Electric, Moa, My Sweetheart, Sybil, lolanthe Extended, Inca No. 1, Golden Castle, and Peruvian. Ptolemy Mine (Area, 219 acres). —This property is being prospected by Eiley and Company, of London, who hold it under option. A large amount of prospecting work has been done—ten drives, varying from 30 ft. to 150 ft.—with a view to cut the Luck at Last reef. Eight men were employed. Tamihana Mine (Area, 71 acres 2,roods 29 perches). —A considerable amount of surface prospecting has been done, and four reefs discovered, varying from 20 in. to 12 ft. in thickness. A cross-cut drive is to be put in to test their value at greater depth. King of Whangamata Mine (Area, 66 acres 3 roods). —About 250 ft. of a cross-cut was put in, and a 7 ft. reef cut and driven on 85 ft. Eight men were employed. Whangamata Proprietary Mine (Area, 294 acres). —This mine comprises the Luck at Last, Luck at Last Extended, and Wharekawa Special Claims, and is now owned by the Whangamata Proprietary, an English company. A large staff of men was employed in carrying on works to' develop the reefs. It is the intention of the company to erect a twenty-stamp battery, to be driven by water-power, which is plentiful and adjacent to the ground. Extensive prospecting works have been carried on in the Phoenix, Golden Mount, Golden Falls, Pukewhau, Three Star, Whangamata, and others. 11— G. 3.

General Bemarks. In this district there has been a considerable decrease in the yield of gold. The principal gold-producing mines were worked down to the extent of the ground opened up, and in the case of the Moanataiari, Cambria, Hazelbank (now known as the Kuranui-Caledonian), and May Queen the principal work carried on has been in the extension of development works and reconstruction of the crushing plants, and not in the actual work of mining and crushing quartz. However, the advancement of the shaft in the Queen of Beauty will before long enable the May Queen Mine to resume operations on the shoots of gold at deeper levels. The Moanataiari Mine also is being thoroughly opened up, and when the new plant is ready the treatment of ore on a large scale will be commenced. The Kuranui-Caledonian Mine has again been cleared to the No. 4 level, and the workings opened up, so that crushing operations will in the future be continuous instead of intermittent, as has been lately the case. The New Alburnia and Tararu Creek Mines are now in a position to yield good returns ; a large amount of development work has yet to be done and machinery erected before an addition to any great extent is made to the annual yield of gold from the newer mines throughout the county. During the year 15,693 tons 15 cwt. 50 lb. of quartz was crushed, for a yield of 10,799 oz. 3 dwt., while 11,367 tons of tailings was treated, for a return of 2,611 oz. 12 dwt., the whole being valued at £34,253 14s. There were 1,527 men employed. Ohinemuri District. This district lies to the southward of and adjoining the Thames County. The land is of a very broken and disturbed character, densely covered with timber, except in the Waihi district, where it is of a more open and less hilly nature. The chief mining districts are Karangahake, Waitekauri, and Waihi, where the mines are turning out to be highly profitable, and where the most extensive and improved machinery is being introduced for ore treatment. The cyanide process is most successfully adopted in the saving of gold, which exists in the quartz in a very finely subdivided state in the various mines throughout Ohinemuri. It is worthy of note that in this district the cyanide process was first introduced. The Cassel Company had an agreement to extract the gold from all ore crushed by the Crown Company at Karangahake, and their manager, Mr. John McConnell, treated a quantity with such marked success that the value of the process soon became established. It will be seen from the following list of claims that a great extent of country has been taken up for mining purposes : —

Maratoto District. Hikutaia Gold Syndicate Mine. —This mine was formerly held by local owners, who, after expending a large amount in prospecting and development work, ascertained that the ore was of low grade, and required to be dealt with on a large scale, for which additional capital was required. Mr. J. E. Banks, general manager, describes the mine and workings as follows : — The Hikutaia Gold Syndicate (Limited) was incorporated in London on the 15th April, 1896. The group of mining properties owned by the syndicate comprises the Maratoto United Special Claim and. several adjacent holdings, containing a total area of about 350 acres. The property is situated at the head of the Pakirarahi Creek, Hikutaia, in the Ohinemuri district of the Thames Goldfield, and occupies the northern slopes of the range forming the watershed between the Waitekauri, Komata, and Maratoto districts. The principal mine-workings are situated on the Maratoto United Special Claim, in which a large lode has been driven upon at six levels a total distance of 2,500 ft. The average width of the lode is 12 ft. A cross-cut tunnel is now being driven, which will intersect the lode 150 ft. below the present workings ; the average total backs obtainable from this adit being 275 ft. A considerable amount of prospecting work has also been done on the other sections of the property, sufficient to prove the persistence of the lode through these areas, which, however, will be worked more advantageously through the adit now being driven. The character of the ore is generally low grade, and large reduction works will be necessary to insure success. The company possesses ample water rights. Walker's Maratoto (Area, 80 acres 2 rood 2 perches).—This mine comprises the original Prospectors' Claim, from which very rich silver-ore was obtained in the early days of Maratoto. There was not much work carried on by the present owner other than opening some of the old workings. In the beginning of 1897 the mine was placed under option to the Mines Corporation Company, and since then work has been vigorously carried on, and in the low levels a continuation of the rich ore worked near the surface was traced. Another reef has also been discovered, the ore being worth about £4 per ton. These results are so far satisfactory that a company with £20,000 available working capital is prepared to take over the mine. It is proposed to undertake extensive works in putting up milling and ore-treating machinery on a scale equivalent to the value of the mine. Arrangements are also made for developing the reefs at a great depth by driving a long low-level tunnel, which will pass through and also develop the adjoining special claim, named the Long Drive. Sixteen men were employed. Prospecting works have also been carried on in the Waitekauri, Magazine, Express, Irving, Ophir, Lord Salisbury, Eetreat, and other claims. Komata District. Komata Queen Mine (Area, 120 acres). —Komata Queen (Limited), an English company, is the owner. A large gold-bearing reef was discovered on the surface, and 326 ft. of driving done to prove it. A considerable amount of cross-cutting was done, and over 1,000 ft. of deep trenching. Twenty-five men were employed. Komata Amalgamated (Area, 344 acres, comprising the following claims : Komata Eoyal, Komata King, Komata Proprietary, each 100 acres, and Komata Chief, 44 acres). —This property was acquired under option, with the exception of the Komata Proprietary section, which has been purchased by the London and New Zealand Exploration Company (Limited). Thirteen prospecting tunnels were put in, and surface trenching done. No defined reef has yet been cut. Twelve men were employed. Komata Beefs Mine (Area, 79 acres). —A large amount of work has been carried on by the Komata Eeefs Gold-mining Company (Limited), the owners of this mine, during the year. The three reefs known as Argall's lode, Lavington's lode, and the Komata reef have been well opened up, and the mine will shortly be in first-class working-order. Tramways are being constructed to convey the quartz from the mine to the new battery, a distance of about 120 chains. A staff of fifty men was employed during the year. The following description of the mine-workings, tramways, and plant has been furnished by the general manager, Mr. W. H. Argall: —■ Argall's Lode: The drive on foot-wall portion of the lode north from the main cross-cut has been extended a distance of 57 ft. A long piece of bottom had to be taken up a length of 218 ft., average depth 3 ft., caused through driving south from No. 2 cross-cut. At a point from main cross-cut 200 ft. north No. 1 rise was started, and rose 52 ft. A further distance northward on this level of 60 ft. No. 2 rise was commenced, and rose 111 ft. Three cross-cut drives, averaging 11 ft., at intervals of 50 ft., were put through to the hanging-wall to show the thickness of the orebody at this level. Also a drive on the hanging-wall portion, 39 ft. long, to prove its value. lam pleased to say that all work done on this portion of the mine is of a most promising and payable nature, besides which, immediately at the point of No. 2 rise, a branch leader was discovered running into the foot-wall. This leader is now known as Hartridge's leader, and has been driven on 101 ft., and proved highly payable throughout. An intermediate level, commencing from surface, and about 250 ft. north from main cross-cut, has been driven a distance of 50 ft., for the purpose of intersecting No. 2 rise for ventilation. A drive northward from the rise on the foot-wall portion of the lode has been made 32 ft. The ore-body at this point is 12 ft. thick, showing payable ore throughout. Argall's lode south from the main cross-cut has been extended a distance of 120 ft.; total length, 145 ft. The ore-body is very large, averaging fully 12 ft. of clean solid stone. The first 70 ft. from the flat sheet the ore is of a very payable character, but from this point south the ore is low grade, which shows that we must expect parts of this large lode to be not so remunerative ; but when further developed on its course there is every reason to expect that we shall discover other rich runs in this direction. Lavington's Lode: This remarkably large body of stone, fully 30ft. in thickness, has been driven upon the hanging-wall portion a distance of 80 ft. north. Although the rock is of a splendid
C—3
86
character in appearance, and carries the best of mineral and other indications for gold, the assays made so far prove the ore to be low grade. This is the whole of the work that has been done on the lode, owing to having no place to stack quartz. The main cross-cut has been extended 47 ft., making a total of 482 ft. Eor ventilation alO ft. water-wheel and fan has been erected, also tail-race completed for same. Pipes from here carry air to all parts of the workings at this level. The low-level cross-cut was started at the beginning of the year, and up to date has been driven a distance of 593 ft. At 578 ft. the Komata reef was cut, being a nice body of stone 5 ft. wide. Assays have been made, showing strong traces of gold. Still, at the point of intersection the ore is low grade. From this point 200 ft. more driving will cut Argall's lode. When this work is completed the company will, without doubt, possess a most important and valuable mine. All these works have been securely timbered where necessary. Ventilation has also been carried into low-level cross-cut by means of a water-blast, which required a small flume and trestling to get the necessary pressure, about 35 ft. This works very satisfactorily. The total amount of feet driven during the year was as follows: Driving and crosscutting on lodes, 512 ft.; rising, 163 ft.; cross-cutting country, 640 ft. We have also in a very forward state earthwork formation completed for 5 chains of ground-tram, commencing from orepaddock and leading to a shoot 70 ft. in length, to convey ore to the hopper, which is constructed, and will hold about 50 tons. From this point a short length of tramway is in course of construction to convey ore to No. 1 hopper, at the upper terminal of the aerial tramway. An assay office has been built and fitted with the necessary appliances, an assayer engaged, and practical assaying carried out at the works. All works have been carried out with a view to practical use and strict economy. The connection between the low level of the mine and the company's battery is being made by, first, a continuously working aerial tramway, a little over half a mile in length, and, second, by a steam tramway three-quarters of a mile in length. The arrangements are made so that the ore will be trucked direct from the low level to the hopper at the upper terminal of the aerial tramway, from which it is to be delivered by a skip to the buckets of the aerial line, which again will deliver it near the lower terminal to a hopper at the head of the steam tramway. From this hopper the trucks are to be loaded, and will be taken by a locomotive direct to the stone-crusher at the top of the battery. In the whole of this work the company are sparing no reasonable expense, so that the ore-delivery from the mine to the mill will be made at the lowest possible cost per ton, and, in pursuance of this policy, the most modern aerial machinery has been obtained, of which practice has actually proved the efficiency for their work. The whole of the tramway-works are being constructed in the most finished and substantial manner. The delivery by the aerial line will be 50 tons in eight hours, but could be very much increased if necessary. The great advantage of this machinery over any so far erected in the district lies not so much in an extraordinary capacity for delivery as in the simplicity and strength of the parts, which make it in a high degree suitable for the work of a permanent mine. The steam tramway is laid at a gradient of lin 30, with a gauge of 3 ft. 6 in., and 401b. rails. The minimum radius of curve is 223 ft. The tramway is made in earthwork 10 ft. wide for the whole length, excepting the four stream-crossings, two of which are crossed by two bridges, each of 30 ft. span, and two by viaducts, one of 134 ft. in length, in seven spans, and one of 30 ft. in length, in two spans. The whole of the timber being used in connection with the works is first-class heart of kauri, and the structures may therefore be considered of a decidedly permanent character. At the present time the earthworks are practically completed both for the aerial and steam tramway. The bridges and viaducts are all built, and the platelaying of the steam tramway and timber-work of the aerial line are now being energetically proceeded with. The first work done was the erection of the blacksmith's shop and an office, the latter containing two rooms, one of which is at present used for sleeping-accommodation for the men working at the plant. The next work taken in hand was making a tail-race and wheel-pit, and laying on the water from the water-race to the mill-site, with 20 in. water-main. A circular saw was next erected and driven by the water-power, to cut timber to be used in the erection of the mill. Up to date the following works have been completed : The building is finished, and the wheel to drive the mill is in place. The assay and smelting furnaces are complete, and the concrete sumps are finished. Three of the steel vats are already completed, and the foundations are in for seven out of the eight. The battery foundations and framing are erected, and the stamper-boxes placed in position; also the stampers. The towers are made and put in position. The revolving roaster and Gate's crusher are on the site, and the work of erecting them is being pushed on. All the machinery and other material is on the ground, and at the end of July the completion of the works will be drawing to a close. The bad weather and bad roads have greatly delayed the progress of the works. We have a water-race constructed for a length of between two and three miles, capable of carrying ten Government sluice-heads of water. This is completed, and in good working-order throughout. The following will be the mode of treating the ore: The ore is tipped from the tramway-trucks into storage hopper at the back of the mill. From there it passes through a No. 2 Gate's orecrusher, and then through a revolving screen, which sizes the ore down to Jin. mesh. From there it goes through a revolving automatic roaster, 24 ft. long by 52 in. diameter. The ore is dried in this, and conveyed from it to a large hopper at the back of the stampers. From this hopper it is fed automatically into the self-feeders, there being four of them, of the Challenge type; it then passes into the mortar-boxes, where the stampers, twenty in number, crush it to 50-mesh. It falls from the boxes into a small hopper at the front of the stamps. At the bottom of this hopper there is an elevator attached, which conveys the crushed ore to a large hopper placed in the centre of the six large steel percolating-vats. The crushed material is conveyed automatically from this hopper to any of these vats, and, after being treated by the cyanide process, and the greater

part of the gold extracted, the tailings are washed through launders on to copper tables. Should any of the coarse gold have escaped the cyanide it is caught on these tables, and the balance of the material is allowed to run into a swamp alongside the mill. The mill consists of the following machinery and appliances : Twenty stampers suited for wet- or dry-crushing, their weight being 8501b. ; a revolving automatic roaster; one Gate's No. 2 ore-crusher, with sizing-screen and elevators; four automatic self-feeders; six 22ft. steel perco-lating-vats ; two steel dissolving-vats, 21 ft. diameter ; three concrete sumps, 12 ft. by 12 ft. by 4 ft. ; and two zinc towers. The assay-plant is complete—melting-furnaces, oxidizing-pan. All furnaces are built in brick, with brick chimney 40 ft. high. The whole plant is covered by a building 90 ft. by 150 ft. and 60 ft. at the highest part, the building being covered with corrugated iron. The machinery is driven by two Pelton wheels, with a head of water of 140 ft. pressure. The following form also part of the plant : One centrifugal pump, one vacuum pump, vacuum chamber, one 60-light dynamo for lighting up the hill, copper tables, and one berdan. Te Ao Marama Mine. —This mine has been worked by the Waitekauri Company, and the works carried on are mentioned in Waitekauri Mine report. Byron Bay Mine. —This land was prospected, and several gold-bearing reefs opened. Prospecting work was also carried on in the National, Triumph, Queen's Birthday, Komata, Treasury, Eoyal Mail, and other claims. Karangahake District. Woodstock Mine (Area, 72 acres 1 rood 18 perches).—Work in this mine has been vigorously carried on during the year, and development of the different reefs effected in order that in the future a supply of quartz may be maintained to fully employ the new forty-stamp mill. The position of the new mill on the point between the confluence of the Ohinemuri and Waitawheta Streams entailed great expenditure in conveying materials and machinery to the site. Delay from this and other causes prevented the completion of the plant in August last, and crushing was only commenced on the 26th February, 1897. This delay has been the means of causing no return of gold to be possible, and the anticipation that the mine would yield an addition to the returns from Ohinemuri for 1896-97 has not been fulfilled. (The returns that have been obtained for the first cleaning-up show that for next year this mine promises to be one of the best gold-producers.) The mine is carefully and systematically worked, and the series of levels opened between the tramwayline and the outcrop of the reefs have disclosed such an abundance of quartz that no difficulty will be experienced in producing large quantities from the portion of the mine already developed. It is, however, intended to carry on operations below water-level at no distant date, and from the ascertained value of the reefs at the present lowest level there is very little doubt that when a shaft has been sunk developments in low levels will prove that the reefs continue in richness. The mine is at present one of the best conducted in the laying-off and execution of all underground work and machinery, and reflects credit on the manager, Mr. J. McCombie, who has supplied the following particulars: — The No. 1 level, Maria lode, has been extended south of the cross-cut about 142 ft. on the line of the lode, which measures 4 ft. in thickness, and carries payable ore throughout for the whole of that distance. Two extensive blocks have been timbered and opened up, with ore-passes and travelling-ways for stoping operations, and a winze sunk to connect with the intermediate level a depth of 130 ft. In the intermediate level, Maria lode, a distance of 137 ft. has been driven along the line of the lode south of the cross-cut. For the first 80 ft. of driving the lode was somewhat disturbed, and the ore low grade in consequence. Thence forward it improved steadily in size and value, and now it is fully 6 ft. wide, carrying payable ore from wall to wall, and signs are not wanting of further improvement going southward. During the year the No. 2 level, Maria lode, has been extended 100 ft., making its total length 688 ft. from the starting-place at the surface cross-cut. At this point 19 fathoms of stoping has been done on the lode, which averages 5 ft. in thickness throughout the whole of these workings, and the ore is all of good quality. The No. 2 level cross-cut has been extended westward a distance of 220 ft., making its total length 700 ft. Several gold-bearing lodes have been intersected, and these will be all exploited as opportunity offers. The No. 2 level cross-cut, Woodstock lode, has been driven upon for a distance of 60 ft. south of the cross-cut and 200 ft. north of the same point. Owing to the disturbed nature of the country, and consequent low-grade character of the ore, work here has been suspended for the present. Since writing last annual report the No. 3 level, Maria lode, has been driven southward a distance of 315 ft., making its total length 855 ft. The lode ranges from 3 ft. to 15 ft. in thickness, and it maintains an average grade of high-class ore so far as explorations have gone upon it, with every indication of improvement going downwards. Stoping over the back of this level is in active operation, and 162 fathoms have been blocked out. A rise has been put up to connect with the No. 2 level a height of 156 ft., and two winzes, 80 ft. and 85 ft. in depth respectively, have been sunk till connection was effected with the No. 4 level workings. Over the back of the No. 3 level, Shepherd's lode, about 72 fathoms of stoping have been done, which varies from Ift. to 6 ft. in thickness, and there is a high percentage of the precious metals distributed through the whole body of the ore. Steady progress has been made with developments at the No. 4 level, Maria lode, which has been advanced 537 ft. for the year, making its total length 612 ft. The lode here averages 4 ft. in thickness, and the ore coming to hand therefrom is all of good quality. Above this level about 45 fathoms of stoping have been carried out, and the resulting ore is all high grade. The distance driven in the No. 5 level, Maria lode, has been 360 ft., making the total length of the level 438 ft. About 200 ft. of this distance has been driven upon the lode, which is very irregular in size and value, and I do not expect any improvement till the level reaches under the shoot of rich ore now being worked upon at the upper levels. The cross-cut west, No. 5 level, is being driven for the purpose of developing
a—3
88
the Woodstock lode at the lowest obtainable level. It is now in 257 ft,, and the lode in question should be met with in another 163 ft. of driving. In the Ivanhoe section of the mine the kiln tram-line has been carried along through the gorge on the right-hand bank of the Waitawheta Eiver for a distance of 500 ft. This involved 398 ft. of tunnelling and 102 ft. of scarfing. The northern continuation of the Maria and Woodstock lodes has been intersected, and driving northwards upon both ore-bodies is now in progress. The following is the average number of men employed during the year : Mine, fifty-six contractors, fifty-four wages-men; mill, twenty contractors, four wages-men: total, 134 men. Eegarding the difficuty of minimising the dust nuisance so prevalent in all dry-crushing plants, we have succeeded in overcoming it, so far as the battery is concerned, by the application of an exhaust fan, which is connected with the mortar - box screens by means of a series of pipes, and we are arranging for the removal of the dust arising from the stone-breakers by adjusting thereto somewhat similar appliances. From the dust-bins to the percolating-vats the reduced ore is being conveyed automatically by a system of revolving conveyors with a spiral screw inside, and the whole concern is working splendidly. Neiv Zealand Talisman Mine (Area, 60 acres). —This mine is situated at Karangahake, and adjoins the Crown and Woodstock properties. The land is favourable for carrying on mining operations, the present adit-level being 700 ft. above the level of the Waitawheta Stream. The principal workings are at No. 6, or adit-level, and Nos. 5 and 4, the levels being each 100 ft. apart. A considerable amount of work was done in driving at the different levels and stoping portions of the reef. The mill, which comprised ten stamps and a complete cyanide plant, was not used to any great extent, it being found that the number of percolating-vats was insufficient, and that a great deal of time was lost in treating the crushed quartz by the cyanide process. From April to September, 1896, 285 tons of quartz was crushed, 280 tons being treated by cyanide, for a yield of 1,429 oz. 5 dwt., and 5 tons by amalgamation, for 5 oz. 14 dwt. The whole of the tailings from the 280 tons were, after the cyanide treatment, run over amalgamation-tables, and yielded 55 oz. 18 dwt. of gold. The value of bullion recovered by cyanide was 19s. lOd. per oz., and by amalgamation £1 10s. 4}d. The average value of the ore before treatment was £5 17s. 6d. per ton. Thirty men were employed at the mine and nineteen at the battery and buildings. On the completion of the treatment of the quartz as above the company decided to erect a more extensive and suitable plant. The following account by Mr. W. A. Mercer gives full particulars of the mine and new works carried on during the year : — The property of the New Zealand Talisman Gold-mining Company (Limited) is situated at Karangahake, in the Ohinemuri district, and comprises the licensed holdings known as the Talisman and Bonanza respectively, each having an area of 30 afires; also a machine-site, 1 acre in extent, on the right bank of the Waitawheta Eiver, and a special site of the same area at the junction of the Ohinemuri and Waitawheta Eivers. On the taking-over of the property by the English company on the 15th June, 1896, the Talisman and Bonanza Licensed Holdings were converted into a special claim of 60 acres. The capital of the new company is £150,000, in shares of £1 each, the working capital being £25,000. The company constitutes the first subsidiary undertaking of the London and New Zealand Exploration Company (Limited), the general management being in the hands of Messrs. Bewick, Moreing, and Co., mining engineers, of London, represented in the colony by Mr. William A. Mercer, with whom is associated Mr. Alfred H. Curtis, another representative of the firm, these two gentlemen being also the attorneys of the company in New Zealand. Prior to the acquisition of the property by the English company some 280 tons of Talisman ore treated at the Crown Gold-mining Company's battery yielded £2,770; and subsequently 285 tons of ore treated at the company's own ten-stamp mill yielded £5 7s. 6d. per ton. Under the new direction the mine has been systematically and rapidly developed, the principal workings consisting of six adits driven at intervals of about 100 ft. below each other (for the purpose of intersecting the main reef), and of extensive drives along the reef in northerly and southerly directions. The width of the reef has varied in these workings up to as much as 8 ft., the average size being probably from S-J-ft. to 4 ft. The exploratory work has proved the existence of at least two shoots of very rich ore in the main reef, which strikes into the Talisman section of the property from that of the Woodstock Goldmining Company (Limited). On taking over the property the engineers in New Zealand were confronted with numerous difficulties in the matter of the reconstruction and enlargement of the reduction-works, owing to the want of a battery-site of sufficient area to allow of the whole of the plant being erected under one roof. This difficulty was overcome by the construction of a Howe truss bridge across the Waitawheta Eiver for the purpose of connecting the machine-site proper with the special site. On the former area there is ample accommodation for the erection of crushing appliances, as well as for a small number of cyanide-vats; but the bulk of the eyaniding will be effected on the works at the special site. The following is an outline of the process adopted for the treatment of the Talisman ore : The ore is conveyed from the mine by aerial tramway, and delivered into the kiln formerly used for drying the ore and now utilised as a storage-hopper. From the kiln the ore passes over a grizzly to a rockbreaker of reciprocatory jaw type, falling thence into a hopper from which it is automatically fed into a revolving ore-drier (a conical cast-iron cylinder 24 ft. in length, 34 in. in diameter at the small end, and 50 in. at the larger, erected with axis horizontal), through which the ore gradually travels towards a storage-hopper lined with sheet iron immediately over the stamper-boxes. The capacity of the drier is from 40 to 50 tons per twenty-four hours, according to the amount of moisture in the ore. The use of this contrivance is a new departure in New Zealand, and is expected to effect a considerable saving in fuel, to obviate loss of cyanide caused by the presence of pieces of charcoal and partially-carbonised wood in ore dried by the kiln process, and to prevent the fusion of fine particles of gold into globules on which cyanide solution cannot effectually act. The pulverising plant consists of ten heads of 850 lb. stamps with single-discharge mortars (these stamps forming part of the mill as originally erected by the old company and ten heads of I,ooolb. stamps

with double-discharge mortars). The remainder of the plant on the machine-site consists of two wooden cyanide-vats, each 16 ft. in diameter (part of the old plant), and four new cyanide-vats each 22 ft. in diameter, into the latter of which the ore is fed by means of a revolving oreconveyor, a horizontally-laid pipe 8 in. in diameter, to the inner surface of which a worm is fitted. Over each of the four new vats there is an adjustable door in the revolving pipe, through which the ore passes when desired into a canvas hose lowered into the vats. The use of this form of conveyor obviates the necessity for the use of trucks in this part of the works, thus greatly reducing the amount of dust in the atmosphere of the building. The tailings, after treatment by the cyanide process, pass over amalgamated copper-plates for the extraction of the coarser gold, and the blanketings are subsequently treated in berdan-pans, of which there are three, 4 ft. in diameter, on the machine-site. Water for the driving of the mill is conducted from the company's dam on the Waitawheta Eiver first through a tunnel 90 ft. in length, then through an open cutting 20 ft. in length, passing finally into a wrought-iron pipe 4 ft. in diameter and 925 ft. in length, delivering the water into a concrete-walled turbine-pit 28 ft. in depth. The motive-power is generated by means of two Victor vertical turbines, 21 in. and 12 in. in diameter respectively, the latter being used for the operation of a dynamo generating electric light for the works and offices, and for the transmission of power to the cyanide works on the special site. The cyaniding plant on the special site (to which ore, after its passage through the mortars, is conveyed by covered tram vid the Howe truss bridge, newly erected over the Waitewheta Eiver) consists of six wooden vats, each 22 ft. in diameter, with the usual accessories, including amalgamated copper-plates and three 4 ft. diameter berdan-pans. The sumps are substantially built of concrete. The centrifugal and vacuum pumps on this site are driven by an electric motor operated by the dynamo on the machine-site. Water for vat-sluicing, &c, is brought to the special site from the Hauraki Creek by means of a pipe 3 in. in diameter. It is expected that the mill will be able to treat a minimum of 25 tons per day, and it is hoped that the stamps will eventually prove equal to as much as 30 tons. A No. 5 Krupp ball mill, recently received from England, will shortly be erected, and may be expected to increase the crushing-capacity of the plant by at least 20 tons per day. In addition to the buildings, machinery and plant, bridge, &c, above referred to, suitable office premises and residences for the mine and battery managers (Messrs. W. Goldsworthy and C. H. Taylor) have been erected since the property was taken over by the new company. Crown Mine (Area, 135 acres 1 rood 31 perches).—This mine, which now includes the Earl of Glasgow ground, is situated on the north and south sides of the Waitawheta Eiver. The river flows through a very deep gorge, the rock on either side being nearly perpendicular, and its direction generally contrary to the run of the reefs. The gorge is virtually a natural cross-cut made by the river, and shows the reefs and veins of quartz as they lie in the rock on both sides. Extensive operations are being conducted. The mine development is expeditiously carried on. The splendid water-power obtainable from the Waitawheta is being utilised in driving air-compressing machinery, and the power developed will provide a supply of compressed air to work all the machinery required at the mine. The battery now consists of forty stamps, and is being converted to suit wet-crushing and the use of cyanide solution in the stamp-boxes. One hundred and ninety-five men were employed. Mr. Daw, the general manager for the New Zealand Crown Mines Company (Limited), has furnished the following short description of the mine-workings, &c. : — During the year ended the 31st March last the mine has been worked continuously to provide quartz for the mill, and for the opening-up of reserves. The principal mining operations consist of the pushing-forward on the course of the Welcome reef of Nos. 4 and 6 tunnels, south of the Waitawheta Eiver, and the putting-up of two main rises to connect with Coward's old workings, the latter in order to provide ventilation and to open up the immense blocks of valuable stopingground between the river-level and Coward's No. 3 level above. No. 4 level has been extended south on the reef about 340 ft., making its total length 1,670 ft. The reef, it will be remembered, was picked up about 60 ft. west of the point at which it was cut off by the great fault mentioned in last report, and, while its characteristics are similar to those north of the fault, its value has greatly improved. Its average thickness is 4 ft., varying from 2 ft. to 10 ft. The reef in No. 6 level, which has been extended 370 ft., was intersected by a cross-cut put out west after striking the great fault, and its position was found to agree generally with the reef in No. 4 level above. It continues to maintain its average width, and the quartz from this tunnel and the stopes above and below it continues to be the most valuable received from the mine. Two main rises are being put up from No. 4 level to Coward's No. 3 level above, a total distance of about 480 ft. on the underlie of the reef. No. 1 of north rise has been risen 150 ft., and No. 2 210 ft. These rises, when completed, will be valuable for ventilation and stoping, as well as for passing filling for the workings below river-level. Stoping has been carried on in the backs of Nos. 4 and 6 levels, the quartz mined yielding an average assay-value of about £4 per ton. Little or no stoping has been done north and south of the winze below the river-level, owing to the incapacity of the small Tangye pump to cope with the inflow of water. During the year 11,737 tons of ore has been mined, of which 10,432 tons was milled, and yielded 7,691 oz. of gold and 9,040 oz. of silver, valued at £33,368. Over 1,600 tons of quartz is stocked at the battery, but, owing to the limited paddock-accommodation, it has been found impossible" to take advantage of the full output obtainable from the mine in its present state of development. Twenty heads of stamps were in operation up to the 10th August last, and since that date forty heads. At the reduction-works the battery, which is now a dry-crushing plant, is being converted into one of wet-crushing; the experiments in this direction up to the present have given most satisfactory results. In the No. 6 level north of the Waitawheta Eiver a chamber has been stoped out for an air-compressing plant. The compressor to be erected is a Eiedler horizontal two-stage tandem type, having cylinders of
C—3
90
17 in. and 26 in. diameter, and 3 ft. 6 in. stroke; working at sixty-five revolutions per minute it will deliver 1,680 cubic feet of free air per minute at 75 lb. pressure per square inch. On the south side of the Waitawheta Eiver chambers have been excavated for pumping- and winding-engines. The cylinders of the winding-engine are 12 in. in diameter and 18 in. stroke. The diameter of the drum is 59 in. and the face 4 ft. The pumping-engine has al4 in. cylinder by 24 in. stroke, fitted with slide-valve with Meyer's cut-off. The whole of this plant is being supplied by Messrs. Fraser and Chalmers (Limited), of 43, Threadneedle Street, London. AlO ft. Pelton water-wheel (3 nozzles) will be attached direct to the driving-shaft of the compressor. The water-race to supply power for the air-compressor is a mile and a quarter in length, with a present capacity of sixty sluice-heads, the pressure being 32 lb. per square inch. A large amount of prospecting work has been done in driving cross-cuts, trenching, &c, in the following mines, but no discovery of any value reported: Hercules, Deep Lead, Excelsior, South British, Karangahake, Mariner, Eothschild, Golden Fleece, Wealth of Nations, Union Jack, Asteroid, St. Patrick, Crown Imperial, Prince Eegent. In the Stanley a considerable amount of prospecting work was done, and gold has been discovered in a reef formerly worked in the original Prospectors' Claim, but no returns are reported. Sterling Mine. —Work has been steadily carried on and the reefs driven on. Waverley Mine (Area, 64 acres). —This mine adjoins the Woodstock, and extensive driving works were carried on and reefs cut carrying gold, but no returns have yet been reported. Mr. Tregoweth, manager of the mine, thus describes the result of operations:— During the past twelve months we struck a large lode, and operations have been confined to its development. We have driven about 400 ft. on it, and the stone proves to be of a sugary friable nature, carrying a little gold, but not sufficient to make it payable. The lode was followed into the Woodstock ground, but as the dip is towards the Waverley ground we will get this lode at the next level. This is an unusual lode for this district, having two clay walls, and the gold in the stone being similar in character to that at the Thames, whilst the formation is a blue sandstone similar to the Thames formation, and is an entirely new development in this locality, nothing being known of it outside the Waverley ground. Work has been stopped on this at present, as it will be necessary to go deeper, and we are now cross-cutting for the old Prospectors' lode, which the manager of the Stanley has picked up in his ground, where it gives good prospects of gold. We are in hopes of getting it in our ground carrying gold, as the country is most favourable for gold where driving is now being carried on. Imperial Mine (Area, 60 acres). —This mine adjoins the Crown, and, although there are several gold-bearing reefs in the ground, no quartz has been crushed. The work has chiefly been in driving a low level at a depth of 300 ft. below the surface, and in driving and sinking winzes in the levels above. Eight men were employed. Prospecting operations have also been carried on in the Eavenswood, Golden Giant, Crown Nimrod, New Shotover, Victor-Waihou, Mere, Eotokohu, Leap Year, Dickson's Lead, Waitawheta, Pandora, and Golden Age. Ohinemuri Syndicate Mine (Area, 700 acres, partly freehold and partly on Crown land). — The property is situated at Owharoa, and includes the claims formerly known as the Smile of Fortune, Eadical, Cadman, on the Ohinemuri Eiver, and extending to the Mangakara Creek, taking in Bein's and Eliott's-freeholds. A prospecting drive from the Mangakara Creek was continued 1,130 ft., and a shaft sunk 20 ft. for ventilation. It is intended to sink a main shaft near the Owharoa battery to work the Smile of Fortune and Eadical reefs below the water-level. Twentythree wages-men were employed. Prospecting works have also been carried on in the Eising Sun, Ophir, Maritana, Owharoa, United, Dawn of Hope, Fern Spur, J. G. Ward, Kinsella's Freehold, Teutonic, Tandem, Euapehu, Crescent, Fabulous, Unexpected, and Golden Stream Claims. Heitman's Freehold. —The shaft which was sunk to a depth of 255 ft. last year was deepened to 267 ft., and a level driven 266 ft., but as the formation was unfavourable for reefs no discovery was made. Waihi District. Waihi Mine (Area, 346 acres). —This mine continues to maintain highly profitable yields. The following particulars will show the character of the work done and the extensive machinery employed, also the results of the year's operations : The No. 1 shaft has not been made deeper, but No. 2 shaft has now reached a depth of 415 ft. The length of the adit driven through the hill is 3,200 ft., and the total drift at adit-level is 6,400 ft. The lowest level worked is 280 ft. below the collar of the shaft. The reefs worked are the Martha reef, north-east and south-west, varying in size from 12ft. to 52ft. in width; Welcome reef, parallel towards the east end, and then bending to the south, travelling west, when it again becomes more parallel with the Martha reef—the Welcome reef varies from 1 ft. to 30 ft., the a.verage width being 12 ft.; Surprise reef, between the Martha and Welcome reefs, is from 1 ft. to 2 ft. wide. The No. 2 shaft has been sunk 123 ft. during the year. No. 2 level: Total driving on Martha and Welcome reefs, 1,902 ft.; No. 1 level, 1,697 ft.; adit-level, 2,677 ft.; and in the upper levels, 70.1 ft.: a total of 6,977 ft. of driving during the year. The tonnage of ore forwarded to the mill from Welcome reef was 21,681 tons, and from Martha 16,704 tons. The machinery used at the mine is as follows : No. 1 shaft—compound pumping-engine, 12 ft. by 20 ft.; winding-engine, 20-horse power, 16 in. by 3 ft. stroke ; one Cornish boiler, 25 ft. by 5 ft.; one Cornish boiler, 26 ft. by 5 ft., one 14 in. pump, pump-rods, balance-bobs complete ; one 10 in. draw-lift pump; one air-compressor; one Evans pump; one duplex pump (Tangye). No. 2 shaft—one Hathorn Davy 19 in. vertical ram pump, 10 ft. stroke; one Tangye sinking-pump ; one steam crab-winch ; one Tangye double-cylinder winding-engine; one Tangye 2-ton crab-winch ; four multitubular boilers (Anderson and Co.). The mill and machinery consists of ninety stamps (8701b.), two stone-breakers (one Wheeler, one Gate's crusher), one berdan,
91
C—3
thirteen kilns, from 50 to 150 tons capacity ; twenty-four vats, 30 tons capacity; mill driven for the most part by water; auxiliary steam-power; one (Gates and Thorn) 350-horse-power engine; one (Golden State) engine, 120-horse power ; one Tangye " colonial," 20-horse power; two Babcock and Wilcox's boilers, one multitubular, and one semi-portable (Fowler and Co.) boiler. The mill worked 354 days during the year, the average number of stamps employed daily being eighty-two, and the average quantity of quartz per stamp daily was 1-195 tons. The quantity treated was 34,410 tons; value per ton (actual), £3 16s. 8-6 d. Bullion recovered — 29,722-53 oz. gold, 63,885-37 oz. silver. Total product, £132,021 14s. 2d. from mill; £3,069 10s. lOd. from tailings, 2,522 tons treated; £109 lis. 6d. from concentrates sold: total, £135,200 16s. 6d. (silver valued at 2s. 3d. per ounce). The whole of the above bullion was recovered by cyanide process. The average number of men employed at the mine was about 350 (irrespective of new works), of which probably two-thirds were employed on wages and the balance on contract work. The company is erecting a new mill at Waikino, Owharoa, a description of which is given in the following extract from Mr. H. P. Barry's general report : — Owing to some little trouble in getting the road-bridge across the Ohinemuri Eiver completed, work on the new reduction plant was somewhat retarded ; but since the bridge has been finished and open for traffic the various works have been steadily pushed on. This bridge is a strong piece of work, 155 ft. in length, the main truss on trestles built on two concrete piers, the decking of the bridge being 30 ft. above normal level of water, which I think will insure its not being carried away by any flood which we are likely to experience. Wherever it was to the company's advantage, all the new works have been let by contract. In this connection seventy-four contracts have been let, nearly the whole of which have been completed. After getting quotations from several firms in different parts of the world, the contract for the supply of the one hundred head of stamps was let to A. and G. Price, of the Thames, New Zealand, who have already delivered a considerable portion of the machinery. The main shafting for the mill and the pulleys has been delivered, as also the two turbines and the two Gate's stone-crushers. The whole of the heavy timber for the mill is on the ground, including the twenty bed-logs, 4ft. Sin. by 2 ft. 6 in. by 18 ft. in length, of good heart of kauri, which were sawn in our own kauri bush. The necessary excavations for these bed-logs, plates, and sills have been completed, and the masons have commenced the erection of the stone wall which is to carry the ore-bins. A considerable amount of work has been done on the tail-race, which has been taken out in a large open cut, but it is proposed to tunnel the rest of the distance. The following buildings were either completed or nearly finished at the close of the year: Store, 60 ft. by 25 ft.; sawmill, 80 ft. by 23 ft. ; carpenter's shop, 60 ft. by 23 ft. ; blacksmith's shop, 50 ft. by 25 ft. ; machine and fitting shop, 60 ft. by 25 ft,; office, 35 ft. by 29 ft. ; locomotive-shed; store and dwelling house. New water-races: The necessary motive-power will be obtained from a high-pressure system of races, ha.ving a fall of 198 ft., and a low-pressure system, having a fall of 54 ft. The high-pressure system consists of three races—the Mangakara Eace and the Stony Creek Eace, both tributaries of and falling to the Waitekauri Eace. The Waitekauri Eace, 6 ft. by 2 ft. 6 in. deep, and below the junction of its tributaries 7 ft. by 2 ft. 6in., is upwards of four miles and three-quarters long, and commences at a dam a few hundred yards below the Waitekauri Gold-mining Company's mill. This race passes under the old kauri bush, through a tunnel 1,530 ft. long, a portion of which has been securely cribbed where it passes through slidy ground. The Waitekauri dam is a substantial wooden structure, 16 ft. high, with a spill of 68 ft., the total length being about 170 ft., with the two wings built of heart of kauri throughout. I do not anticipate that we shall have any trouble with this dam for many years to come, as it was subjected to a very severe test soon after completion, when we experienced very severe floods, and it stood the test well. The dam on the Mangakara is a permanent piece of stonework, upwards of 30 ft. in length, and running from 2 ft. to 8 ft. in height. The Mangakara Eace, 5 ft. by 18 in., is upwards of 22 chains long, passing through a tunnel 268 ft. in length. The dam on the Stony Creek will be a wooden structure upwards of 45 ft. in length. The Stony Creek Eace is nearly half a mile long, 3 ft. wide by 18 in. deep. The pipe-line for conveying the water from these races to the mill is of wrought-iron, 2 ft. 4 in. in diameter, and upwards of 1,200 ft. long. The low-pressure system consists of the Ohinemuri Water-race, four miles and an eighth long, 12 ft. by 4Jft. deep, running for the most part on the south bank of the river, but will cross at one place to the north bank by a high trestle flume, and recross again to the south bank after a distance of about a quarter of a mile. These crossings, although expensive, were unavoidable, owing to the nature of the ground. With the exception of these flumes just referred to and a wrought-iron syphon-pipe 5 ft. in diameter and about 475 ft. long, the whole of the race has been carried through a ground-channel, so as to obviate the constant repairs that would inevitably be necessary after the elapse of a few years where fluming to any extent on a water-race obtains. The dam on the Ohinemuri, at the intake of this race, will be a strong and solid structure of masonry. It was considered advisable to do this rather than to construct it of wood, so as to prevent any possible danger in the future through the wood rotting and serious damage being done to dams, bridges, flumes, &c, further down the river. The extra cost will not be very great. The water from this race, which has a fall of 1 ft. in 2,000 ft., will be conducted to two 200-horse-power vortex turbines by a pipe-line 4 ft. 6 in. in diameter, branching off into two pipes of 3 ft. 6 in. in diameter, fitted with equilibrium-valves for each turbine. The length of the tramway from mine to Owharoa Mills is, approximately, five miles and threequarters. It has been constructed of a gauge of 2 ft. 9 in., the smallest curve having a 6-chain radius. It has been well graded throughout, being, with only one exception (which has an up-grade of 1 ft. in 90 ft.), all down-hill with a load, the steepest grade being 1 ft. in 40 ft. The line crosses from the north to the south bank of the Ohinemuri Eiver, at a distance of two miles and three-quarters from the mine, by means of a strong truss bridge, upwards of 185 ft. in length, and 30 ft. 6 in. high from 13—C. 3.

water-level to decking, and built of good sound heart of kauri and totara. The whole of the formation of this tramway has been completed, and upwards of -three miles laid with heart of kauri sleepers and 40 lb. iron rails. All the culverts have been made with glazed earthenware pipes, which will be more durable than wooden culverts; and all the swamps which the line traverses have been drained by good substantial drains. The locomotive has been put together, and is now busily engaged ballasting the line and hauling building-stone to the mill. Twelve of the iron side-tipping trucks are on the ground, and we have received advice that fifty more, which should be sufficient for our requirements, are now on their way out from England. Union Mine (Area, 250 acres).- —This mine is adjacent to the Waihi Company's ground, and is held by the Union-Waihi Gold-mining Company, an English company. A large amount of development work has been done during the year. No. 1 shaft is now 270 ft. in depth, and the depths of workings below surface are 177 ft. on Amaranth and 120 ft. on the Union reef. The Amaranth reef at No. 1, or adit level is 112 ft. below collar of shaft; and the Union reef at No. 4 level is 120 ft. below the collar of the shaft. The Amaranth reef varies from 14 ft. to 28 ft. in width, running nearly north-east and south-west, and is free milling, with large amount of silica. The Union reef varies from 4 ft. to 9 ft. in width, running north-east and south-west, and is of freemilling ore, rather soft and clayey; and the Winner reef undeveloped in No. 9 drive. Other works are as follow : Cross-cut driven to Amaranth reef, 486 ft.; cross-cut through country, 620 ft.; driving on Amaranth reef (adit-level), 787 ft.; cross-cutting, Amaranth reef, 107 ft.; winzes sunk on Amaranth reef, 420 ft.; other drives, winzes, and cross-cuts, 861 ft. : total, 3,281 ft. The whole of the above is development work, as the company does not at present possess any mill. The No. 1 shaft has now (15th April) been sunk to a sufficient depth to allow of another level being driven to the Union reef 80 ft. below the lowest workings. A cross-cut will also be driven at this level to the Amaranth reef, which will intersect it at a depth of 160 ft. below the adit-level. The distance to drive will be, approximately, 300 ft. to the Union reef and 450 ft. to the Amaranth reef. Thirty men were employed. Waihi-Silverton Mine (Area, 174 acres). — This mine has been continuously worked during the year. The shaft has been sunk to a total depth of 180 ft., which will give another 80 ft. of backs where the reef is opened up. The average width of the reef is about 10 ft. The total quantity of quartz crushed amounted to 7,922 tons, which yielded 6,605 oz. of bullion, of the value of £15,289. Sixty-one men were employed. The forty-stamp mill is in fairly good working-order. The mill has been provided with exhaust fans for the removal of the dust caused by the dry-crushing. These fans have the effect of carrying off the dust, and when further improvements are made it will be possible to alleviate the evil. The Gladstone Mine, which is now owned by an English company, had a staff of men employed for several months past in sinking a shaft and clearing out the old levels formerly driven in the mine. Favona and Brilliant Mine (Area, 200 acres). —The land is situated to the eastward of the Waihi and north of the Silverton. The chief work carried on during the year has been in sinking the mam shaft. The size of the shaft is 14 ft. by 6 ft. in the clear, timbered with 9 ft. by 9 ft. framed sets, heart of kauri, and divided into three compartments, two for winding and one for pumps. Thirty men were employed. The management have supplied the following description of the mine and machinery : — At a depth of 70ft. from surface a cross-cut was put in for a distance of 100 ft. in a westerly direction. This work intersected a large ore-body, fully 60 ft. through. The course of this reef is north and south, and underlying about 20° west. Various assays were taken from this reef, varying from 4s. to £1 12s. per ton; and the last 120 ft. sunk in the shaft has been in quartz from which assays have been taken with similar results to the reef cut in 70 ft. level, and the general character of this ore-body resembles the Silverton very much. Hitherto the water has been lifted from this shaft by a 7 ft. by 4 ft. Tangye's pump, but as depth was obtained the inflow was so great that it quite overpowered the pump. It was therefore decided to cease operations in the shaft until the plunger and draw-lift could be put in. Previous to work stopping in shaft a chamber Bft. wide by 10 ft. high and 15 ft. long was cut out at 200 ft., or 10 ft. from bottom of shaft. It is the company's intention to drive two cross-cuts from this level, one to go east-south-east and the other west-north-west. It is also the directors' intention to put down another shaft about 30 chains north of the present shaft. This work will not be started until the Martha reef can be correctly located in the ground. Some loose quartz which has assayed up to £6 per ton has been got about 60 chains east of the present workings. The pumping machinery consists of a plunger and bucket-lift, 12 in. diameter, with a differential stroke of 6 ft. and 4 ft. respectively. The motive-power is obtained from a compound condensing horizontal tandem engine with cylinders 16 in. and 26 in. diameter, with a stroke of 36 in. Keyed on the crank-shaft is a spur-pinion 3 in. to 4 in. diameter, geared into a spurwheel. 10 ft. diameter, 5 tons in weight, and prepared to receive a crank-pin for the 6 ft. or 4 ft. stroke, as may be required. The fly-wheel of the engine has a gross weight of 10 tons. The engine is also fitted with a crank-shaft governor connected to an automatic cut-off valve. This cut-cff valve has a range of from 0 to three-fourths of the stroke of the engine. The boiler for supplying steam is of the multitubular horizontal type, 16 ft. in length, with a diameter of 6 ft. The tubes are sixty-six in number, running longitudinally, and with an outside diameter of 3J in. Twelve of these tubes are of greater strength, and are chased, and secured with lock-nuts so as to form stays. Above the tubes there are also six longitudinal bolt stays 2in. diameter; below the tubes are two gusset stays. The thickness of shell is fin., and the boiler is designed to carry a working-pressure of 1501b. to the square inch. This mine is now owned by the Waihi Consolidated Gold-mining Company (Limited).

Waihi-Grand Junction Mine (Area, 280 acres). —This mine comprises two blocks of land—the Grand Junction section, of 190 acres, adjoining the Waihi Mine, on the north-east; and the Waihi West section, adjoining the Waihi Mine, to the south-west. In the Grand Junction section a shaft has been sunk to a depth of 507 ft. and a cross-cut driven at that level 167 ft. to the northward and 199 ft. to the southward of the shaft. The shaft was sunk for the first 250 ft. through the rhyolite deposit, and the remaining distance through the andesite or favourable rock, similar to what is found in the Waihi Mine adjacent. The reef, however, has not been cut in this end. In the Waihi West section a shaft was sunk to a depth of 170 ft. and a drive put in to the northward for 601 ft. To the southward a drive was put in, and at a distance of 430 ft. from the shaft a reef was cut, supposed to be the Martha reef, worked in the Waihi Mine. This drive has been further extended a distance of 350 ft., with a view of intersecting the Welcome reef, also in the Waihi Company's mine. The machinery used at the Grand Junction shaft consists of one 40-horse-power multitubular boiler, 16 ft. by 5 ft.; one Tangye 7Jin. by 12 in. winding-engine, with 4 ft. 6 in. drum; three Tangye vertical special pumps, throwing about 5,000 gallons of water per hour each from a depth of 507 ft. : at the west section, one 30-horse-power multitubular boiler, two Tangye boilers, one Davy pump, two Tangye vertical special pumps, and one hauling-engine with pair of 6 in. cylinders. Mr. J. M. Chambers, the secretary of the Waihi-Grand Junction Gold Company (Limited), of London, informs me that "the company has expended £18,000 in addition to £5,000 by the syndicate before the company was formed. If a good reef is discovered more machinery will be put down to develop the mine and a crushing plant will be erected." Forty-eight men were employed. Waihi Consols Mine (Area, 2,000 acres). —This mine adjoins the west section of the Grand Junction Mine. A shaft was sunk to a depth of 160 ft., but further development was not undertaken from there. The shaft in the west section of Grand Junction was then used, and the northern drive continued for 200 ft., but no discovery was made. Six men were employed. Prospecting was done in the Mount Waihi and Sir Julius Claims, of 100 acres each, but, as sinking must be carried on, work has been suspended pending further arrangements being made. In the Waihi Extended and Star of Waihi very little work has been done, and in the Waihi Eeefs a shaft has been sunk to a depth of 170 ft., with a view of striking the Amaranth reef. No further work has been done in the Queen of Waihi. Martha Extended (Area, 130 acres). —In this mine, which lies about three miles north-west of Waihi, a considerable amount of driving has been done from different drives, one 383 ft. and the others 125 ft., 102 ft., and 112 ft. Several well-defined reefs have been cut, carrying a little gold and silver. Six men were employed. Waihi Monument (Area, 100 acres). —This mine lies about four miles east of Waihi Township. The shaft was sunk to a depth of 110 ft., and a drive put in from the bottom of the shaft 86 ft. It is intended to sink to a depth of 160 ft. in order to get into more solid country, and then cross-cut for the reef, which on the surface is from 12 ft. to 15 ft. in width. Eight men were employed. Great Northern Mine (Area, 100 acres). —The land is situated about five miles north of Waihi, and near Wharekiraupunga. Two reefs were cut in surface drives, and a low level advanced 211 ft., in order to cut the reefs 100 ft. deeper. The first reef is 4 ft. in width, and the other, which is of a flinty nature, is 45 ft. wide. It is expected that the reefs will be cut in the low level when the drive is extended to 330 ft. Four men were employed. King of Waihi (Area, 89 acres). —Three prospecting drives were put in, of a total length of 500 ft. ; a large reef of flinty quartz 20 ft. in width was cut, and also a number of quartz veins. Three men were employed. Mataura Mine (Area, 86 acres). —Driving to the extent of 648 ft. has been carried on to cut a reef 12 ft. in thickness, consisting of hard flinty quartz. Four men were employed. Waihi South Mine (Area, 128 acres). —This mine is situated to the westward of the Waihi Township and to the south of the Waihi West. A shaft has been sunk to a depth of 150 ft., and a drive put in from the shaft to the southward 50 ft. and northward 150 ft. No quartz has yet been cut. Two Tangye boilers, with pump and steam-winch for winding, is all the machinery used. Thirteen men were employed. Prospecting works have been carried on in the Waihi Golden Pinnacle, Waitete, Waitete Extended, Waihi Proprietary, Queen of Waihi, Ohinemuri, El Dorado, Waihi Eeefs, Waihi Welcome, Waihi Mint, and Flower of Waihi. Wharekiraupunga District. A large amount of prospecting has been done in the Eoyal Standard Mine. The reefs are being opened up and a tramway made to a point on a creek where machinery can be landed. A large battery of forty stamps is to be erected near the mine, and, as there is ample water-power adjacent, this company will be in a position to treat quartz of low grade. The mill is to be fitted with all the latest appliances in gold-saving. Mr. J. G. Ealph, the manager, gives the following account of the mine and works :— The low-level tunnel has been driven a total distance of 151 ft., at right angles to the general course of the various lodes traversing the property. This is sufficiently large to admit of a horsetram line being laid. The country-rock is a very hard, splintery, close-grained andesite. The Eoyal Standard main lode will be intersected at this level, at a total distance of 640 ft., giving 380 ft. of backs, and affording crushing material for years to come before sinking is resorted to. The Le Messurier level is being driven along the foot-wall side of the Le Messurier reef. Bore-holes are drilled at equal distances along the lode, and the borings assayed, which proves the quartz to be highly payable. A cross-cut is to be commenced at a point 200 ft. from the mouth, and driven
C—3
94
through the reef, where a junction of two other smaller reefs with the Le Messurier is expected to be met with. In the Le Messurier cross-cut the total distance driven is 62 ft.; another 220 ft. of driving will intersect the Eoyal Standard main lode on the south side of the creek. The lode on the spur through which the cross-cut is penetrating is a splendid body of stone. Sulphides of silver, associated with extremely finely divided particles of gold, are freely seen in the large pieces of ore strewn about the surface of this spur. From here we expect a long run on highly payable ore. The Junction cross-cut will intersect the main lode on the northern slope of creek in 30 ft. of driving, and will pass through a further distance of about 60 ft. to reach the western branch of the lode, from which good dish prospects are obtainable on the surface. The want of storage-room for the quartz broken out necessitates the stoppage of development works on the various reefs until the tram-line is connected with the quartz hoppers. The total distance driven in the intermediate level is 95 ft. The rock here being near the surface is an oxidized andesite (propylite), through which progress is more speedy. The main lode will be intersected here at a point some 800 ft. north of the Junction cross-cut. A shoot for the conveyance of the quartz to the tram-line will shortly be in course of construction. The bulk of the crushing-ore will be obtained from the Le Messurier, Junction, and intermediate levels for a considerable time to come. The tram-line for the transit of quartz to battery is being constructed from the low-level tunnel to the kiln-site, a distance of 20 chains. From the entrance to the Junction cross-cut a bridge is to be constructed across the main creek, at the south end of which a large storage-hopper is in course of erection. The tram-line from this hopper will be cut around the precipitous rock to the mouth of the Le Messurier level. The tram from the Le Messurier to a point opposite the lowlevel tunnel is being made, and when a quartz hopper is erected a stretch of tram-line from this to the low level will complete the tramway formation. Great difficulties have to be contended with during the formation work, very precipitous rocks, the crust of which is extremely hard, towering up perfectly straight for 200 ft. The water-race formation, when completed, will have a total length of 40 chains, giving 197 ft. of fall. The excavation for battery is being carried on with expedition. A firm class of sandstone is met with for the foundations of stamps. The site will shortly be in readiness for the cyanide plant. Bricks for the assaying-furnaces can be made close to the battery-site. The greater portion of timber for the battery, water-race, hoppers, &c, is ready at the different pits, and a tram-line is being laid down in readiness for conveyance of timber to the battery-site. Mr. Charles Judd, of Thames, is the contractor for the manufacture and supply of a forty-head dry-crushing stamper-mill and a cyanide plant of the latest type, the whole plant to be erected without delay. The natural position of the mill-site enables the quartz, when once dumped into the kilns, to pass by gravitation through the whole mill without handling. The main-line formation of the railway from battery to landing is complete a distance of 4 miles 52 chains. This work is at a standstill until the arrival of the rails from England. The company is experiencing great difficulties in conveying supplies to its property. The Ohinemuri County Council appear to take no interest whatever in opening up this district. The Eoyal Standard Company have for some considerable time employed upwards of two hundred men, which surely entitles them to something in the matter of roads. Prospecting works have also been carried on in the Atlas and La Mascotte, where several goldbearing reefs have been discovered. Work was also carried on in the Devon, Gold Stream, Eoyal Shield, Tavistock, Prince of Wales, Fiery Cross, Sceptic, Day Spring, and Waitekauri-Tavistock Eeefs Junction. Waitekauri District. Waitekauri Mine (Area, 507 acres and 25 perches).—This mine comprises the following claims: Golden Cross Special Claim (Golden Cross section), 100 acres; Croesus Special Claim (Golden Cross section), 100 acres; Socket Special Claim (Golden Cross section), 99 acres 2 roods 6 perches; Te Ao Marama Special Claim (Komata section), 97 acres 3 roods 36 perches; Crosscut Special Claim (Komata section), 100 acres ; Waitekauri Licensed Holding (Waitekauri), 9 acres 2 roods 23 perches : total, 507 acres and 25 perches. The important development works projected last year have to a great extent been carried out. The low-level adit cross-cut has been extended, and No. 1 and No. 2 shafts sunk to a depth of 282 ft. and 86 ft. respectively. The mine is worked from three levels, viz. : Corbett's level, a drive in the side of the hill about 22 ft. below the level of the sill of No. 1 shaft; kiln level in the north, and battery level in the south, at a level of 129 ft. below the level of the sill of the same shaft. The reef consists of a dark-coloured quartz strongly impregnated with manganese and partially-oxidized iron-pyrites. It varies from 12 ft. to 20 ft. wide of payable ore, but at points is of a much greater width than this. Development work carried on at the Golden Cross section during the year is as follows: Sinking the two shafts; the extension of Corbett's, kiln, and battery levels ; driving the Corbett's, kiln, and battery cross-cuts to prospect the ground to the west of the reef; and driving the low-level tunnel or adit-level. At Waitekauri Licensed Holding the work consists of a prospecting drive to get under a rich shot of gold worked by the original company. At the Komata section the work has been the opening-up of the magazine level gully drive, the extension of Nos. 1 and 2 levels, and the driving of the aditlevel from the eastern side of the hill. The machinery used in mining operations consists of two air-compressors, one with 12 in. air-cylinders, belt driven by water-power, used for working the rock-drills; the other 12 in. air-cylinder 2 ft. stroke combined with steam-engine with 12 in. cylinder, used for working two Tangye pumps in the shafts. The quartz from Corbett's level is brought to mouth of the drive in tram-wagons, and that from kiln and battery levels by the same means, through kiln and battery cross-cuts respectively. There are also four miles and a quarter of tramway connecting the mine
95
C—3
with the forty-stamp mill. The machinery used for milling comprises one forty-stamp mill of I,ooolb. weight each stamper and one ten-stamp mill of 6001b. weight each stamper. There are also two stone-breakers; eight kilns, each of 250 tons capacity; and two, each of 200 tons capacity; nineteen vats, each of 30 tons capacity; and three, each of 23 tons capacity. The power for the above milling plant is water, with an auxiliary steampower. Water-power : Two 6ft. Bin. Pelton wheels to work the forty-stamp mill; head of water, 195 ft.; length of wrought-iron pipe, 2,000 ft.; length of water-race, three miles and a quarter; one 4 ft. Pelton wheel for working vacuum pump ; one 6 ft. Pelton wheel, with 162 ft. head of water, for working ten-stamp mill ; length of 10 in. main pipe, 835 ft.; length of water-race, 123 chains. Auxiliary steam-power : One compound condensing engine, 150 indicated horse-power, with two Babcock and Wilcox boilers of 190 indicated horse-power for forty-stamp mill; one high-pressure horizontal engine, 24 indicated horse-power, with one multitubular boiler for ten-stamp mill. The average quantity of quartz crushed per stamp-head daily for the forty-stamp mill is 1-5 tons, and for the ten-stamp mill 0-67. The average number stamp-heads employed daily was —forty-stamp mill, 37 ; ten-stamp mill, 10: total, 47 heads. The number of days worked during the year was—ten-stamp mill, 313; forty-stamp mill, started in August and worked until the 31st March. The total quantity of quartz crushed was 11,410 tons, giving 30,232 oz. bullion; value of £32,645 extracted by the cyanide process. The cost of mining, per ton, was 9s. lid. The cost of milling and treatment, per ton, was 17s. 3d. The average number of men employed during the year was 352 : all wages-men. New Zealand Jubilee Mine (Area, 292 acres 2 roods 25 perches).—Work has been steadily carried on during the year. The low-level adit has been extended 576 ft,, and a considerable amount of work done on Christie's and No. 2 reefs. No returns of quartz crushed have been received. Twenty men were employed. This low-level tunnel is being subsidised by the Government, and £42 12s. has already been paid on account of subsidy. Young Neiv Zealand Mine (Area, 14 acres 1 rood 12 perches).—This mine, which is owned by the Young New Zealand Gold-mining Company, is situated at Waitekauri, adjoining the Waitekauri United and Sovereign, and in close proximity to the old Waitekauri Licensed Holding. The land includes the old Welcome and Young New Zealand Claims, which were profitably worked in the early days of Waitekauri. The quartz was then treated by the old battery process, which did not save a very large percentage of the gold. Since the present company took over the property some of the old workings have been repaired and timbered, for the purpose of proving by sinking whether the reef maintains its richness at a lower depth. The first winze was sunk 43 ft., and from the bottom 2 tons of quartz were sent to the School of Mines at Thames, the value of which was stated at £6 ss. 9d. per ton. 80 ft. further north another winze was sunk 14 ft., and operations were suspended on account of the influx of water. From this winze 1 ton was sent to Auckland for treatment by the Fraser process, its value being given at £18 12s. The results from these trial parcels are satisfactory, and the low level, which will give 150 ft. of backs, is advanced 450 ft. up to date. About 200 ft. more driving should intersect the reef, which varies in size from 2 ft. to 4 ft. 6in. The hanging-wall portion is heavily mineralised, and the foot-wall portion full of blue sulphide veins. Assays made from stone that would give a prospect by pounding and washing by the old battery process were very rich. There are a number of other reefs that have proved to be goldbearing, varying in size from 34 ft. to 4 in. ; in fact, there is a network of reefs and small leaders, so that when a battery is erected the mine promises to be a gold-producer. Five men were employed. Grace Darling Mine (Area, 90 acres). —This mine is situated on one of the branches of the Waitekauri Stream, about two miles up from the Township of Waitekauri. About two years ago a mill was erected and a portion of the reef worked, but the results were disappointing. The mine is now opened up in a more systematic manner, and hopes are entertained that, although of low grade, the quartz may prove payable if large quantities are economically treated. The claim comprises the land formerly known as the Progress, Grace Darling, Portsea, Prioress, Vendor, and Pyramid Licensed Holdings, each of which was held by a separate company, but amalgamation was effected, and the Grace Darling Company is sole owner. The following is a description of the works done in the mine :— The property comprises an area of 90 acres, originally held in six 15-acre licensed holdings, and known as the Progress, Grace Darling, Portsea, Prioress, Vendor, and Pyramid Licensed Holdings, which are now amalgamated. In the Grace Darling section No. 1 level has been opened up for a length of 150 ft. on the reef, and has an average height of about 60 ft. of backs. The reef, which is of a friable nature, varies in size from 2 ft. to 8 ft. Three rises have been put up to the surface. In No. 2 level a cross-cut was put in, and the lode intersected at a distance of 175 ft. The reef, where cut, is about 5 ft. in thickness. A block about 40 ft. long and 30 ft. high has been stoped out and treated at the mill. The treatment was found to be unsuitable for the class of ore, and, as a consequence, a large percentage of the gold was lost, as no provision had been made for saving the tailings. This level has been opened up for a distance of 500 ft. Three rises have been put up to No. 1 level a height of 82 ft., and passes and chutes constructed at regular intervals. A winze has been sunk about 10 ft., and gold is showing in the bottom of the winze. The average width of the reef is about 6ft., and in the south face about Bft., all of which is gold-bearing. The gold does not seem to be uniformly distributed through the stone, but occurs in narrow runs or shoots. At the No. 3 level a cross-cut 300 ft. in length was required to intersect the reef at a depth of 110 ft. below No. 2 level. The lode, where intersected, is about lift, in thickness, and has been driven on for a distance of 25 ft. along the foot-wall side. No gold has been seen in this level, but portions of the quartz taken from it have given very favourable assays. In the Portsea section No. 1 level has been opened up for a distance of 250 ft., and two rises have been put up to the surface for ventilation. The reef has an average width of 8 ft., carrying gold in
C—3
96
places. No. 2 level has been opened up for a distance of 315 ft. at a depth of 72 ft. below No. 1, and is connected with it by rises and winze. The average width of the reef is about 5 ft. Some dabs of gold have been seen, but the greater part of the ore is of low grade, easily procured, and of a free-milling character. In the Progress, Prioress, Vendor, and Pyramid sections operations have been confined mostly to surface prospecting and trenching. A number of reefs and leaders varying from 6 in. to 3 ft. in thickness have been discovered, but there has not been sufficient work done on them to prove whether they are of a payable nature. Nine men were employed. The mine is well opened up, and the present owners, having exhausted their funds, have placed the property under offer to an English company for the purpose of furnishing sufficient capital for the erection of suitable machinery, as the present ten-stamp mill is inadequate to deal with low-grade ore. A considerable amount of prospecting has been done in the Waitekauri King, Golden Spur, Omega, Dorothy, Waitekauri No. 2, Waitekauri South, New-Zealander, Exchange, Southern Cross, Belmont, Golden Waitekauri, Jewel, British Empire, Oceania, Huanui, Waitekauri Eeefs, and Waitekauri Queen Claims, but no valuable discovery has been reported. Alpha Mine (Area, 30 acres). —This mine is situated near the old whim on the tramway to Komata. Three levels are opened, and four reefs, varying from 3 ft. to 14 ft. in width, have been worked on, but the quartz is generally of low grade, and until suitable machinery is available no returns of gold can be obtained. Four men were employed. The Eainbow Claim, of 60 acres, has also been prospected, and several reefs, varying from 2 ft. to 6 ft. in width, have been tested, and found to be of low grade, which to be payable must be dealt with in large quantities. Four men were employed. Waitekauri United Mine (Area, 109 acres). —This mine is now held by the Waitekauri United Gold-mining Company, Limited (English). A staff of forty-five men has been employed in driving tunnels to cut the reefs which are known to exist in this property. A 14-horse-power steam-engine is used for driving the air-compressor to work the rock-drills. Although several gold-bearing reefs are to hand, the crushing machinery is not to be erected until further development has been done. Mr. F. Stone, mine-manager, gives the following account of the work done : — During the past ten months this company commenced operations to open up the mine by tunnelling. No. 1 tunnel is now in a distance of 500 ft. into the main range. Several small leaders were cut, assays from which vary in value from 14s. to £6 per ton. We expect to cut the main reef in this tunnel in another 160 ft. of driving. This tunnel is being driven through the main range 2,800 ft. to meet No. 2 tunnel, which is started from the opposite side of the range, and will give from 220 ft. to 345 ft. of backs on the reef. No. 2 tunnel is now in a distance of 440 ft., but nothing of any importance has yet been met with; but it is a well-mineralised country, favourable for gold, and I would not be surprised to strike a good reef at any time. No. 3 tunnel is started at a point near the north-western boundary, and is now driven 293 ft., its course being south-west. We have passed through several small leaders, but not of any great value, although the class of country is favourable. No. 4 tunnel has been driven 40 ft. in a southerly direction from the northern boundary. No. 5 tunnel is now in a distance of 170 ft. from the south-west side of the range, to intersect what is known as the " United Blow," and to prove this part of the mine at a deeper level, as there was a good deal of gold got on the surface in the early days. The upper level, on the point reef, has now been driven a distance of 320 ft. on the line of reef, which varies from 6 ft. to 18 ft. in width, and the assay-value is about £2 per ton. There will be about 150 ft. of backs above this level. We have started a low-level to cut the point reef; it will give about 90ft. of backs to the level above. This cross-cut or low level is now in a distance of 92 ft., and we expect to strike the reef in another 30 ft. of driving. We have also opened up several drives on the old workings. The Energetic reef has been driven on for a distance of 100 ft.; the size of the reef varies from 2 ft. to 4 ft. in width, and assays about £3 10s. per ton. Waitekauri Gross Mine (Area, 100 acres). —This is owned by an English company, the Waitekauri Cross Gold-mining Company (Limited). It is situated on the line of reef worked in the Waitekauri Mine, and the following development work has been carried out during the year: An adit is being put in from near the south-western boundary in an easterly direction, with a view to intersecting the well-known Golden Cross reef. This is now in progress, and is already in about 600 ft. During the construction of this adit the Taranaki reef (formerly cut on surface) was intersected, and driven on for 100 ft. in a northerly direction. It proved to be a large lode, varying in width from 18 ft. to 30ft., with a strong dip to the east. There is little doubt but that this lode is the same as that being worked in the Waitekauri Extended ground. In addition to the above, a cross-cut was put in for 300 ft. from the south-eastern boundary in a north-westerly direction. At the present time a shaft is being sunk near the eastern boundary adjacent to the surveyed line of the Golden Cross lode, from which it is proposed to open out in order to intersect this reef. Twenty-five men were employed. Waitekauri Extended. —Work was carried on at different parts by tunnelling with small surface tunnels to find out the exact course of the lode; about I,oooft. of driving was done. It was then decided to drive a cross-cut tunnel 160 ft. below the surface at the top of the range, and in the centre of the Hippo section, to be known as the " blow tunnel." This was driven a distance of 400 ft., passing through a favourable channel of country, and cutting ten different defined reefs. The last reef, No. 10, which looked the most promising, and gave the best results, was at once opened up and driven on about 250 ft., cross-cutting at every 50 ft. It proved the reef to be 35 ft. wide at this level. A tunnel 55 ft. lower down was also driven into and through the No. 10 reef. At this level the reef was opened and driven on north and south over 400 ft., cross-cutting as above east and west. The reef in this level proved to be about the same thickness, and better in value. The country passed through in all these upper levels is of the favourable rock found in the Waitekauri district, and the lode itself is evidently on the run of and somewhat similar to the Waitekauri reef.

The workings in this mine up to the present, and no doubt in future, will be the means of leading to the developing and opening up a large tract of country known as the Hikutaia Falls and the watershed of that river. A low level has been driven a distance of 500 ft., and is 200 ft. lower down than the above-mentioned workings. All buildings connected with the working of a large mine are being erected, such as manager's house, men's quarters, blacksmiths' shops, assay-room, &c, and everything will soon be in working-order. The water rights and machine-sites which were obtained for the company consist of five water rights and two machine-sites, and ample water for a large crush-ing-mill can be obtained. A water-race is being constructed, consisting of a ditch, about 500 ft. of wood fluming, and 950 ft. of iron piping 16 in. in diameter. This water-race is about three miles long, and has about 380 ft. of a fall, and is estimated to give about 460-horse power. A forty-stamp crushing-mill is being erected on the battery-site, and will shortly be completed. The mill was ordered and obtained from the Union Ironworks, San Francisco, and consists of 1,000.1b. stamps, two double-discharge mortars, two large Comet rock-breakers, 6 ft. Pelton wheel, large wooden vats, &c, and we hope to be crushing and in full swing about September next. An aerial tramway of a very large size and a mile and a quarter long has been obtained from Fraser and Chalmers, London, and will, I think, be erected within ten months. In the meantime a temporary tramway, consisting of partly ground and partly wire, is being erected, and will be ready for transmitting the ore from the mine to the battery before the mill is ready to crush. The work has been carried on carefully, and will be one of the best plants in the district. The prospects of the mine are such as to warrant the expenditure which has been incurred. The reefs are large, and on account of the facilities for working and the character of the ore the cost of reduction and treatment will be reduced to a minimum. A considerable sum of money was expended on making roads, to which the Ohinemuri County Council have contributed. This work, of course, had to be performed before the machinery could be got on the ground, and the road will largely assist in the opening-up of this part of the field. About 110 men were employed. Prospecting work has also been done in the Bombadier, Musketeer, Brigadier, Takapuna, and Consols by surface tunnels, for the purpose of tracing and locating the large lode worked in the Waitekauri Extended. Some 1,000 ft. of driving has been carried on in these properties. Prospecting operations were also carried on in the Nebraska, Australia, Marburg, Pilot, and Central properties owned by the Waitekauri Union Claims (Limited), an English company. Prospecting was also carried on in the Zion, Queen Annie, Waitekauri Consolidated, Norena Key of Komata, Wangakara United, Burbank, and Alpha Extended. The Waitekauri Union Claims comprise in the western section (228 acres 3 roods 20 perches)— the Pilot Special Claim, the Pilot Extended Licensed Holding, the E.M.C. Licensed Holding, the E.M.C. Extended Licensed Holding, the Central Licensed Holding, the Central Extended Licensed Holding, and the Californian Licensed Holding; in the eastern section (406 acres) —the Australia Special Claim, the Nebraska Special Claim, the Anglian Special Claim, and the Marburg Special Claim. These were taken over by the Waitekauri Union Claims (Limited) in August, 1896, and extensive prospecting operations will shortly be commenced. General Bemarks. In this district success still attends the principal mines. The returns from the Waihi, Silverton, Waitekauri, Crown, Woodstock, and Talisman Mines are most satisfactory, and the mines are so well opened up that ore reserves are in sight sufficient to keep up a continuance of rich returns for several years to come. New mills will shortly be ready at the Waitekauri Extended and Komata Eeefs Mines, whilst other mills are in process of erection at the Eoyal Standard, Cross, and other mines. The yield of gold from the district for next year may be confidently anticipated to exceed that of the present year. The mills are used for dry-crushing and cyanide treatment. In the mill at the Crown Mine, however, the manager is again resorting to wet-crushing, using cyanide solution instead of water in the stamp-boxes. The quantity of quartz treated last year was 64,463 tons 4 cwt., for a yield of 148,626 oz. 8 dwt. The quantity of tailings treated was 2,522 tons, the whole producing gold and bullion of the value of £218,067 19s. 9d. During the year 1,820 men were employed. Te Aroha District. This goldfield is situated to the southward of Ohinemuri, and includes part of Ohinemuri and Piako Counties. The claims taken up are on the northern, southern, and westerly spurs of Te Aroha Mountain. The ore is chiefly of a refractory character, requiring special treatment. The past returns of gold were, however, obtained from the parts of the reefs not highly mineralised. Substantial parcels of ore have been sent to England, with a view of ascertaining a method of profitably dealing with the large quantities of quartz in the various lodes. The following list shows the claims taken up in this district:—

Waiorongomai District. Aroha Gold-mines (Limited) Mine (Area, 395 acres). —This company also owns water rights and machine-sites. The property includes the greater number of claims which produced most of the bullion from this part of the goldfield when worked by companies with small capital. The minemanager reports as follows : — The works carried on have been prospecting and development. Two winzes have been sunk, the total depth of which is 202 ft. 6 in. A distance of 763 ft. has been driven in cross-cuts, and 883 ft. has been driven on the reefs. The amount of ore treated was 708 tons, of which 308 was crushed wet with amalgamation, while 400 tons was dry crushed, and treated with cyanide. The percentage of bullion extracted by w 7 et-crushing and amalgamation was 42 per cent., against 85 per cent, yielded by dry-crushing and cyanide. The plant consists of a ten-stamp battery, one small stone-breaker, and one kiln, and the power used is water. Each stamp crushed per day 35 cwt. of wet and 1 ton of dry quartz. The battery was working sixty days, and the average number of men employed during the year was fifty (including wages-men and contractors). The company are now driving a main low tunnel to open up their property in a systematic manner. The dimensions of the tunnel are 11 ft. high by 9 ft. wide in the clear. Its length up to the present is 300 ft. Aircompressing machinery is now on the ground, and will be used to work rock-drills in the formation of this tunnel. A water-race is in course of construction, which will give over 600 ft. of fall, and provide power for working the air-compressor. The tunnel is being driven along the main reef, which outcrops the entire length of the property, a distance of two miles and a quarter. The backs will average 1,400 ft., and the greatest depth reached will be 2,200 ft. The tunnel will not only

open up the main reef, but will intersect numerous cross-reefs where they junction, and will be of great service to the adjoining properties, by enabling them to work at a great depth without being troubled with water. This will no doubt become the main outlet for the ore for the whole district. The intention is to erect a large plant to treat the ore, and have a locomotive to convey it from all parts to the mill. The company have already spent about £10,000 in prospecting, development, oretesting, and machinery, and are doing everything possible to hasten the completion of the main low tunnel, which is estimated to cost over £30,000. Seddon and Cadman. —A considerable amount of work has been done in prospecting the various reefs formerly opened in this mine. It is understood that an option has been obtained over this property, and sufficient capital will be forthcoming to still further continue development works, and then, if satisfactory, the purchase will be arranged. Prospecting work has been carried on in the Welcome, Loyalty Palace, New Munster, Great Western, and other mines. Montezuma Mine (Area, 70 acres). —This mine is situated on the western slope of the main range, and extends from the boundary of the hot-springs reserve to within 8 chains of the Champion Mine. A large number of reefs traverse the ground, varying in thickness from 3 ft. to 6 ft., and generally of a highly-mineralised character. The situation is such that 900 ft. of backs on the reef can be had with a moderate length of cross-cut. Three men were employed. Mr. John Williams, one of the owners, supplied the following particulars : — " Machinery is about to be erected in the near future, under the supervision of the Eev. Joseph Campbell, who is at present in England procuring a complete plant for treating the quartz by what is known as the " thermo-hyperphoric process" (Messrs. Lockwood and Campbell's patent). A company has been formed and registered in London to work the properties. A second company is being formed for the treatment of ores (refractory and otherwise) on an extensive scale. This process is guaranteed to give a return of from 90 to 95 per cent, of the assay-value of stone treated, at a cost of from ss. to 7s. 6d per ton." Prospecting operations have also been carried on in the Taranaki, Hot Springs, Golden Crown, Ethel Eeef, Gipsy King, Mount Morgan, and other claims, from which no returns have been received. Tui District. Champion Mine (Area, 98 acres). —This mine is now owned by the Tui Gold-mines (Limited), an English company. During the greater portion of the year there was very little work carried on, but on the new owners taking possession a staff of twenty men were employed, and the old levels and workings put in order, and a parcel of 25 tons of stone taken out and sent to London for experimental purposes. It is intended to ascertain the most improved method of dealing with the complex ores found in the mine, after which suitable machinery is to be erected. Prospecting works have been carried on in the Silver Star, Grand Junction, Day Dawn, Silver King, Golden Band, Waitara, and other claims, but no report of any valuable discoveries has been received. General Bemarks. Several claims are worked by English owners, and extensive works are carried on, notably by the Aroha Mines Company, at Waiorongomai, which is engaged in driving an adit tunnel from the outcrop near the township. This tunnel is designed to be extended two miles and a quarter, and will have a depth from the surface at the northern end of some 1,800 ft. The yield of gold in this district was from 934 tons of quartz, and amounted to 376 oz., of a value of £986 10s. During the year sixty men were employed. Tauranga County. ; Te Puke District. Clarke's Freehold (Area, 300 acres). —Three drives have been put in : No. 1, near surface, 40 ft., in which a reef about 9 ft. in width has been cut; No. 2 drive, 40 ft., of which 25 ft. appears to be quartz and reef formation; in No. 3 drive 90ft. has been put in, and the reef is expected to be to hand when 100 ft. has been completed. Two men were employed. Te Puke Gold Beefs, formerly Fleming's Freehold (Area, 1,087 acres). —A large reef was cut in the north cross-cut, and although 40 ft. was driven through it the wall was not reached. In the south cross-cut the reef was 20 ft. in width, and in the low level, 57 ft. deep, the reef was 24 ft. The quartz is generally of low grade ; samples assayed varied from 6s. Bd. to £6 3s. per ton. The mine is well situated for being worked, as the outcrop is 480 ft. above the creek-level, and there is sufficient power obtainable from the creek to work machinery. Six men were employed. Kaimai Valley and Katikati Districts. A number of claims have been taken up in the locality and prospecting carried out, but so far no important discoveries have been recorded. Accidents in Gold-mines. There was one fatal accident caused by an explosion, and two accidents of a serious nature from other causes, whilst four slight accidents were also reported as being due to explosives. James May was injured by falling down a pass in the Waihi Mine on the Ist April, 1896. A miner named Myers was in the act of pressing half a plug of gelignite into a previouslyexploded hole when an explosion took place. This occurred in the Sheridan Mine on the 16th May, 1896. The manager of the mine reports that Myers will lose one of his eyes. Samuel Baker was injured by an explosion of gelignite in the Waihi Mine. It appears two charges were fired and only one report was heard. Baker went back at once, when the second charge exploded, causing him to be injured. 14—C. 3.

John Dabb was injured in the Talisman Mine on Ist July, 1896. Dabb was picking the mullock thrown by a shot when a slight explosion occurred, injuring him in the face and eyes. Joseph Develin was killed in the Waihi-Silverton Mine on the 14th August, 1896, whilst drilling a hole in which there was an unexploded charge of gelignite. Andrew Douglas was severely cut about on the head in the Crown Mine, Karangahake, on the 18th September, 1896. A charge of gelignite was exploded, but he did not get out of the way in time. Thomas Mulholland was attending a winch at Preece's Point Mine, Coromandel, when he lost three fingers through his right hand coming in contact with the teeth of the winch. John Terrill had his leg broken on the 17th March, 1897, through a piece of stone falling on him in the Whangamata Mine. Machinery. It will be seen from the following enumeration of machinery supplied and erected by one engineering firm alone that great expenditure is necessary in connection with the mines throughout the district:— Kauri Gold Estates, Whangapoua: Small prospecting plant, for sinking shaft, &c, usually supplied for this purpose ; a pair of winding-engines, 5 in. by 10 in., complete, with all pit-head gear ; a Tangye vertical sinking-pump, with rubber disc-valves, to throw 3,200 gallons per hour 250 ft. vertical, the same driven by a Tangye colonial pattern tubular boiler of 12-horse power. Dacre's Freehold (Henry Green), Coromandel: A plant similar to above, but a 12-horse-power boiler. Hauraki South Gold-mining Company, Coromandel: A plant similar to above, but a 14-horse-power boiler, now being completed. Zealandia Gold-mining Company, Coromandel: A plant similar to above, but with a 12-horse-power boiler. Kathleen Gold-mining Company, Coromandel: Prospecting plant, for shaft sinking, with all gear belonging to same, to enable the shaft to be sunk while main plant is being erected, with pumps to deliver 8,000 gallons per hour ; permanent plant consisting of two 25-horse-power Tangye Cornish boilers, one pair Tangye's improved forward-geared winding-engines, with two drums, cylinders 10 in. by 22 in. ; main pumping-engine, compound coupled non-condensing —low-pressure cylinder 24 in. by 30in., high-pressure cylinder 16 in. diameter, fly-wheel 13 ft. diameter by 22 in. on face, with Meyer's patent expansion-valve, &c.; Cornish pumps and all pit-work complete; poppet-legs and gear, with buildings. Hauraki Main Lodes (Limited), Coromandel: A small plant complete for shaft sinking, as previously mentioned. Permanent plant is now in course of erection. This will be a duplicate of the Kathleen Company's. The Tangye pumps now in use will lift 10,000 gallons per hour. The permanent pumps will lift 500,000 gallons per day, which is now being done by the Kathleen, with valve only open fin. The Hauraki Golden Shore have ordered a small pumping and winding plant similar to the Hauraki Main Lodes. The Britannia Company have replaced their small boiler with a 20-horse-power colonial pattern, built in, and have increased the pumping power. The Waihi Gold-mining Company have put down a pair of Tangye winding-engines, 10 in. by 22 in., same size and pattern as the Kathleen Company's. Waihi Union Company : A pair of Tangye winding-engines, same size and pattern as Waihi Company's. The Waitekauri Company have also put down a pair of winding-engines similar to the above. The Waihi Extended have ordered a small pumping and winding plant similar to others, but have delayed erection. Waitekauri United Gold-mining Company: We have supplied this company with air-com-pressing plant, consisting of an Hirnant air-compressor, 12 in cylinders, three rock-drills, &c, driven by a 25-horse-power Tangye under-fired tubular boiler. Waihi Gold-mining Company, Waihi: We have supplied this company with al4 in. Hirnant air-compressor complete, for driving Tangye pumps, &c. Waihi Union Company, Waihi: We supplied this company with a duplicate to above. Waitekauri Company, Waitekauri: We have supplied this company with alO in. Hirnant aircompressor, with pulleys, &c, for belt-driving (water-power); also a 12 in. compressor for steam, same pattern as above. Waihi Consolidated Company : This company has put down a Tangye winding-engine, pair of 10 in. by 18 in. cylinders. Waihi South Gold-mining Company, Waihi: This mine has added to its plant a 12-horse-power colonial-pattern boiler and a Tangye pump to lift 7,200 gallons per hour. These are the principal items supplied and erected. There has been a great number of pumps and general machinery supplied to companies, with the erecting of which the firm had nothing to do. The Crown Company, Karangahake, has been fitted up with a complete installation of electric lighting. Woodstock Gold-mining Company, Karangahake : We have fitted up the battery, &c, with an electric-light installation complete. Waihi Gold-mining Company : This battery has been also fitted up with an electric-light installation, driven by a Victor turbine. The new battery for the Waihi Company is also being fitted up with a complete electric-light installation. The following table shows the number of tons of stone and mullock crushed, and the yield of gold from the northern goldfields, since the returns have been supplied to the Mines Department.

The Hauraki Mine has not maintained an output of rich specimens ; therefore it is apparent that the bulk of rich ore from this run has been worked out. At Kuaotunu also the Try Fluke (now Mariposa), the Great Mercury, and the Irene Mines have not been continuously worked. The output of quartz has thus been materially lessened, and the yield of gold consequently reduced. These mines must in future be provided with more suitable crushing machinery for economical treatment of large quantities of quartz, and until this policy is adopted an increase in the yields cannot be expected. The yield from the Kapai-Vermont Mine has also greatly fallen off, consequent on the richer runs of gold having been first taken out, and until additional machinery is erected for treatment, and development work done to provide reserves of ore, there is no likelihood of increased returns. In the Thames district the greatest falling-off has been in the returns from the May Queen Mine, the reason for this being that the lower levels could not be worked pending erection of the Queen of Beauty pumping plant ; therefore, until drainage has been effected and fresh blocks opened on the reef, a steady output cannot be maintained. The indications at water-level are so good that when the water is drained off rich yields will assuredly follow. In the Moanataiari Mine development has taken the place of production, and until the new plant is available no further treatment of quartz will be undertaken. The mine is being well opened up, and continuous yields will in the future be maintained. Another cause of decrease in the yield from Thames has been that, in consequence of other sources of steady employment being available, the tribute system has almost been given up by the miners, and returns from that source are very limited. The improved return in Ohinemuri County has been caused by a slight increase from the Waihi Mine, whilst during the year the. Waihi-Silverton Extended has largely added to the increase. The Crown Mine and the Waitekauri Mine, consequent on greater crushing facilities, have also exceeded their past year's production. The Woodstock and Talisman Mines, at Karangahake, the Komata Eeefs and W T aitekauri Extended, at Waitekauri, with the extensive crushing-power available, will increase next year's yield to such an extent that this district will be far in advance of any other quartz-mining centre in the colony in the value of its gold production.
MIDDLE ISLAND. Attention has been directed to quartz-mining in the Collingwood and West Coast districts, consequent on the introduction of capital to work the mines. Prospecting operations have been carried on and extensive areas taken up in the Lyell, Victoria Eange, and Paparoa Eange districts, as well as in the different localities around Eeefton. The number of claims shown in the following lists as having been registered in the Wardens' offices gives evidence of the keen interest manifested by those engaged in mining pursuits.

time. The first rush took place over twenty years ago, and, as a matter of course, the easiest payable alluvial deposits were then worked out. There are still terraces of alluvial drifts containing a fair percentage of gold, which will, in my opinion, be worked at no distant date, but up to the present the great difficulty has been want of sufficient capital to bring in water to work these terraces. This is well worth trying, and should it prove successful it will give a considerable amount of employment to miners. A great deal of gold in the creeks is found adhering to quartz, which leads miners to believe that rich lodes will be found on this company's property. A lode was discovered some sixteen years ago on the eastern side of Slaty Creek, which was worked for a time, giving payable returns; but when the payable portions of the lode became exhausted it was stopped, like many others in New Zealand, for the want of capital to further develop it. About the same time there was also a reef worked, and a five-stamp mill erected, on Friday Creek; but this only worked for a short time, as the quartz crushed from here only yielded at the rate of 4 dwt. to the ton, and the reef, being small, was not of a payable character. This company has pegged off three blocks of 150 acres in different localities, which they have reserved for gold-mining, but at present they are only opening up the Golden Eidge Mine. The work done during the year has been confined to driving two adit-levels from the side of the hill, and the sinking of two winzes on the reef from Nos. Ito 2 levels. The reef has varied from 8 ft. to 2in. in width, but it was where the reef was thickest that the best tests were obtained. Some of the quartz treated yielded at the rate of 131 oz. of gold to the ton. This, of course, is not what may be considered a fair average, but it was sufficient encouragement for the company to erect a battery, the works in connection with which are in course of construction. The battery is to consist of twenty stamps, 8J- cwt. each, four berdans, and one concentrating-pan. This is to be driven by a Pelton wheel. The tank where the water is to be lifted in pipes will be 150 ft. above the battery, which will give a pressure of 1831b. to the square inch, so that a small quantity of water will drive the entire plant. The quartz will be conveyed to the battery by an aerial tramway a distance of 60 chains, and this will be connected by a ground tramway from the mine to the upper terminus, the distance being- 350 ft. The company is energetically prospecting their property, and making tracks through the country, at considerable expense, and without Government aid, thereby giving a great amount of employment, over sixty men having been employed constantly during the year. In doing this they are worthy of praise, and it is earnestly hoped that the mines will turn out equal to their most sanguine expectations. There are also three other English companies working mines and carrying out prospecting operations on the company's estate, and meeting with a fair amount of success. The Australasian Gold Trust and Pioneer Company, of London, have also a property of 100 acres at West Wanganui, where prospecting operations are being carried on. An adit has been put in 200 ft., a second 195 ft., and a winze 125 ft. The reef, which runs north and south, is from Ift. to 4 ft. in thickness, the foot-wall being slate and the hanging-walls sandstone. Twenty men are employed. Lyell District. United Italy (Area, 30 acres). —This mine is the property of the United Italy Gold-mining Company (Limited), and has been worked by a party of six tributers. The quartz is chiefly obtained from leaders ; 100 tons yielded 420 oz. of gold. Lyell Greek Extended Mine (Area, 57 acres 3 roods 32 perches).—This mine is worked from the Lyell Creek low-level tunnel. The reef was struck after 3,000 ft. of driving, and two winzes were sunk, one to a depth of 150 ft., and a level opened at 125 ft. Work was, however, suspended in this part of the mine, and a new shaft commenced between the north and south blocks, which is now sunk to a depth of 50 ft. It is the intention of the company to erect a hauling plant to be driven by compressed air. Six wages-men and four tributers were employed. United Alpine Mine (Area, 96 acres 2 roods 28 perches).—This mine is worked from a low-level tunnel 3,000 ft. in length, from which an incline shaft was sunk 520 ft., and a low-level, No. 9, and an intermediate, No. 8, opened from the incline-shaft. 2,215 tons of quartz yielded 713 oz. of gold, and for tributers 65 tons yielded 70 oz. Thirty wages-men and six tributers are employed. Mr. Shallcrass, the manager of the company, gives the following account of the work done, &c. : — "During the year the main incline-shaft has been extended a distance of 200 ft., and the No. 9 level driven. A new air-compressor has been placed in position, and a line of 3 in. wroughtiron pipes, about 6,000 ft., has been laid from the battery to the air-winch at top of incline-shaft. An aerial tramway has been erected from No. 4to No. 7 level. For haulage, a winch driven by compressed-air, 4-horse power ; for pumping, Tangye's pump, capacity 15 gallons per minute, driven by compressed air. The battery consists of twenty heads of stamps and four berdans, the weight of stampers being 800 lb. There are also two air-compressors, 10-horse power each, for hauling and pumping, all of which are driven by water-power." It would prove of benefit to both the "United Alpine and the Lyell Creek Extended Companies if they could arrange to make a connection between their several levels. About 200 ft. of sinking is required from the No. 9 level of the Alpine to the low-level tunnel. Both mines would then be in a better position. The upper mine would be drained, and the lower mine as well as the upper be thoroughly ventilated. All quartz could be sent out by the low tunnel, thus saving hoisting on the part of the Alpine Company. Tyrconnel Mine. —This mine has again been profitably worked, the quartz being chiefly obtained from leaders. A parcel of 44-J- tons yielded 254 oz. of gold. Golden Grown Claim (Area, 50 acres). —This claim has been prospected by the owner, Mr. J. Grieve, and a gold-bearing reef, 5 ft. to 12 ft., and a leader of 12 in., also gold-bearing, have been discovered. Maruia. About twelve months ago gold was found in a quartz reef outcropping on the surface here and there for about a mile in length. It was first discovered in Wheel Creek, about three-quarters of a
113
C—3
mile up from the Maruia Eiver. Some of the outcrops showed a fair quantity of visible gold, and there were all the indications of good reefs being opened up in this locality. The prospectors made arrangements with the Anglo-Continental Gold Syndicate (Limited) to develop the property, but after prospecting it for about nine months by adits, shafts, and winzes it proved that the gold did not go down ; the only place where prospects were obtained of the quartz being payable for working was on and near the surface. The syndicate therefore abandoned the option over the property. These reefs are in the same formation as those recently found on the top of the Victoria Eange, being a metamorphosed clay slate, having in places a semi-schistose structure. The general impression is that reefs payable for working will be found in this locality yet, but it may take a considerable time to discover them, as the district is very sparsely populated. The Warwick Gold-mining Company applied for a lease of 100 acres of ground, and have already put in a drive of 100 ft. on the reef, which is from 2 ft. to 4 ft. thick. Six men are employed. The Grassmere lease, of 100 acres, and Maruia lease, of 16 acres, are also being surface prospected. The Zealand lease, of 30 acres, is also being prospected, and a winze being sunk on the reef from the top of a hill 700 ft. above the river. Britannia Mine (Area, 99 acres 3 roods). —This mine is situated at Stony Creek, Eepublic Eange, Waimangaroa. Prospecting has been carried on continuously, with from two to four men, in opening up the outcrop, driving levels, and testing reef. The quartz averages from 2 oz. to 3 oz., and the recent discovery of quartz in a lode about 20 chains west of No. 1 reef has proved to contain rich ore. An English syndicate has had the property under option for the past five months. Eeefton District. Victoria Bange. —A very rich discovery of auriferous quartz was made by Mr. Kerwan on the Victoria Eange in December last. The locality is situated about eight miles from Capleston, near the summit of the Victoria Eange, at an elevation of about 3,500 ft. above sea-level. There are about 10 acres of ground covered with a loose surface deposit of quartz, which has come from some reef in the immediate vicinity, but so far this has not been found. The ground on which the quartz is lying is a portion of a slip of considerable magnitude. This has been proved by an adit, which was driven into a low spur about 40 ft. below the surface on the summit of the spur. This adit is on loose disturbed ground, the rock being greatly disjointed and tossed about. The ground where the deposit of quartz is lying now forms a portion of the Lord Brassey Special Claim, comprising an area of 100 acres, which was granted to the prospector. On the northern boundary of this claim there are three other claims—namely, the Lady Brassey, Mark Twain, and Earl Brassey—each comprising an area of 30 acres, and on the eastern boundary there is another claim of 30 acres, known as Kerwan's Reward. On the Mark Twain, Earl Brassey, and Kerwan's Eeward Claims there are large reefs outcropping from 3 ft. to 6 ft. in width, but the quartz is far more crystalline in these reefs than in the surface deposit on the Lord Brassey Claim, and, as far as has been tested by assays, only contains a very small percentage of gold, some samples only giving a trace of gold, while others vary from 2-J- dwt. to a few grains to the ton. The formation where the reefs occur on this range is a metamorphosed clay slate, having in places a schistose structure of Devonian age, and older than the Maitai rocks in the locality of Eeefton, which belong to the Carboniferous period. It is a formation where one would expect to find rich auriferous lodes. The surface deposit of quartz on the Lord Brassey Claim must have come from a large lode, as some of the boulders are 2 tons in weight, but the general character of the loose quartz is in pieces varying from a few pounds to two or three hundredweight, all of which contain gold ; indeed, it is a rare instance to break up one of the boulders in which gold is not seen, and, even if it cannot be discerned by the naked eye, by pounding up the stone in a mortar and washing the pulverised material in a dish a very good tail of gold can be got. From the quantity of timber that is growing on the ground where the deposit of quartz is lying it shows that ages must have passed away since any slip took place in the vicinity, and there is no surface indication to show from what direction the slip came, other than from the wavy surface of the ground. One would suppose it came from the direction of the Lady Brassey and Mark Twain Claims. There is a high sharp ridge running across these claims, having a very steep slope down into a deep ravine facing the Lord Brassey Claim, which bears some indications of a slip having taken place, but whether it is from this direction the slip has come is a question at present unsolved. There is no doubt that the large quantity of quartz that is strewed over the surface has come from some reef in the vicinity, and one at no great distance from where the deposit is lying, as from the physical features of the country, and being on an isolated high range, it could never have been laid down in the position it is lying in from glacier action. It may take a considerable amount of time and money to find the reef where this deposit came from, but when it is discovered it is likely to prove one of the richest reefs ever opened out in the colony. Progress Mines of Neio Zealand (Limited). —This group of properties, formerly worked as two separate mines, has since its acquisition from the local owners been in process of development and equipment. The old equipment is entirely inadequate for the requirements in the future, the shafts being small and at too great a distance from the ore-bodies, and the hoisting machinery practically useless for handling the tonnage the mines are now in a position to turn out. The mill was of an ancient type, and is being replaced by one of a more economical pattern and greater capacity. The ore reserve when the mines were purchased amounted to but a few months' run for the mill, owing to the backwardness of development work. The present condition of the property, with its large ore reserve, has been brought about by devoting all attention to opening up fresh ground and
C—3
114
milling only such ore as came from development work. As little or no work has been done outside of known ore-bodies, the amount of dead-work required to develop the present ore reserve is greater in proportion to the tonnage developed than may be reasonably expected in the future. The nature of the ore occurrence will always entail a large amount of development, but with the property properly opened up, as it will be before the new mill is in operation, this need seldom interfere with ore extraction. The new shaft (shaft B) now being sunk has three comparments, two ft. by 4 ft. for hoisting, the third for ladders and piping. It is timbered in square sets, and will cut the vein on its dip at a depth of about 1,200 ft. Through this shaft it is intended to extract all ore-bodies below 500 ft. in depth, and, as it is already down 625 ft., and progressing at the rate of about 20 ft. to 25 ft. per week, the systematic opening of the mine is assured before the new forty-stamp mill is ready to crush. The following work has been done since February, 1896 : Drifting on vein, 1,911 ft. ; raised or sunk on vein, 804 ft. ; cross-cutting, 1,016 ft. ; shaft-sinking (B), 625 ft.; surface tunnel, 200 ft.; reopening old levels and shafts, 1,450 ft.: total, 6,006 ft. Station cut, 26 ft. by 13ft. by 10ft. The following surface-work has been done: Road-construction to shaft B, halfmile ; water-race construction to new mill, two miles and a half; water-race construction to shaft B, three-quarters of a mile; grading for shaft-house, hoisting engine, &c.; grading for new mill; clearing line of aerial tramway; construction of miners' boarding and living houses; grading for sawmill plant at mine. Work in the mine has developed a satisfactory showing of ore. The tonnage developed above No. 6 level is 50,000 tons, as against 23,000 tons reported on the 28th September, 1896. The completion of the shaft and opening of the level 100 ft. below No. 6 should add 30,000 tons to this reserve, and will provide over two years' supply at 120 tons per day. All the machinery necessary for the complete equipment of this property has been ordered; some of it has already arrived in New Zealand, and the remainder should reach here shortly. The grading and the foundation walls for the mill are nearly completed. Most of the lumber for the structure is on the ground, and the work of framing and erecting will begin at once. Two miles and a half (including the most difficult section) of the race for the supply of water-power to the mill is practically finished, two miles further has been benched, and there are a hundred and fifty men on the work to push the completion of the total miles. The heavy grading for the hoisting-works at shaft Bis nearly at an end, and the foundations for the new engine and boilers are about to be built in. Nothing but severe weather preventing outdoor work on the water-race should delay starting regular operations beyond the beginning of the coming year. Wealth of Nations Group). —This group is situated two miles and a half in a southerly direction from the Town of Eeefton ; it adjoins the Inangahua Tunnel group on the south and the Keep It Dark Mine on the north. The group is composed of the following claims : Southern portions of Gladstone, Beaconsfield, and Undaunted, 130 acres; Energetic, 23 acres 1 rood 38 perches; Wealth of Nations, 63 acres 1 rood 13 perches: total, 216 acres 3 roods 11 perches. Through the slates which form the country-rock there runs a mineralised belt in which irregularly-shaped bodies of free gold ore occurs. This belt runs about 15° west of north, and has an average dip of 70° to the west. The ore-bodies vary in size up to 180 ft. in length and 20 ft. in width. On the surface there were three parallel ore-bodies in the Wealth of Nations, worked to a depth of 700 ft. through surface tunnels. One of these ore-shoots struck into the Energetic, and formed the ore-body on which that mine worked until 1895, the output being 65,763 tons ; value, £131,703. The other ore-bodies were worked to a depth of 450 ft. in the Wealth of Nations, but there appears to be a barren zone about 300 ft. in depth making horizontally along the strike of the ore-belt in which little of value has ever been found. This extended through the Energetic, Wealth of Nations, and in a somewhat lesser degree through the Keep It Dark Mine to the south. Below this zone ore was again encountered on the 200 ft. level, Wealth of Nations, and carried down continuously to the lowest workings. The mine below the battery level has been worked through two underground shafts, ropes being brought 750 ft. through a cross-cut to No. 1 shaft, thence down to the 200 ft. level, and 600 ft. along that level to No. 2 shaft. Power furnished by an overshot water-wheel. The limited amount of work such a system could perform has directed all efforts towards an installation which would permit the opening-up of the Energetic ground from the lower levels of the Wealth. Connection has been made with the lowest Energetic workings, and an incline-shaft is being sunk to hoist ore and waste to the battery level. Since taken over the following work has been done : Drifting on vein, 1,182 ft.; cross-cutting, 247 ft.; sunk, 499 ft.; old drifts, air-shafts, and winzes reopened and retimbered, 1,840 ft.: total, 3,768 ft. The water-race, furnishing water and power for milling and hoisting, has been enlarged for a distance of four miles. As both the Keep It Dark and Wealth of Nations ore-bodies have been picked up below the barren zone it is reasonable to expect a like result with the Energetic ; hence every effort is being made toward pushing development in this direction. All hoisting and milling is done by water-power, and the twenty-stamp mill is in sufficiently good order to treat the ore-bodies now developed. When the Energetic ore-shoot is picked up some remodelling will be necessary. Inangahua Tunnel Group.-—Work has been continued in this group. The tunnel has been advanced at the rate of 146 ft. per month since starting (18th September, 1896), and ore has continued to be developed in the ground towards which the tunnel is being driven. No further attempt has been made to open the old Golden Fleece workings, as it is the intention to exploit this ground from below. The winze being sunk from the lowest workings of-the Golden Fleece for the purpose of tracing down the vein to the level of the tunnel 600 ft. below was started on the extreme end of the low-grade body of ore developed in this mine. It is now at a depth of 145 ft., and has carried more continuous ore than could have been expected from its position. It is a promising indication of what should be found below. In the tunnel the last 650 ft. driven has been in likely-looking slate; three stringers of quartz have been cut, two of which are worthy of further investigation. The face of the tunnel is in 3,989 ft., and the point at which the zone carrying the gold-bearing
115
0.-3
veins was expected to be encountered was 4,000 ft., so that this belt of country is 650 ft. wider than was anticipated. 650 ft. further should bring us to where the vein being carried down in the winze should be found, when drifting to the north along the strike of the vein will put the tunnel under country carrying known ore-bodies higher up. The following work has been done: Drifting on vein, 591 ft.; cross-cutting, 133 ft.; raised or sunk, 240 ft.; reopened old workings, 180 ft.; Inangahua Tunnel driven, 1,089 ft.; reopened caved portion, 200 ft.: total, 2,433 ft. 800 ft. of road has been constructed to the mouth of the tunnel. Boiler and air-compressor and an air-winch for hauling in empty mine-cars have been installed. Boatman's Group, consisting of the Welcome United, Fiery Cross, Cadman, Seddon, and Blake, is situated one mile from the Town of Capleston and twelve miles by wagon-road from Eeefton ma northerly direction. The ground comprised in this group has been the scene of great activity in the past. £198,600 has been paid in dividends, and the mines were opened to a depth of 1,500 ft. below the surface. The Welcome United has given the largest returns of this group, having paid £110,250 of the amount above mentioned. The average grade of the ore in this mine was 2 oz. 8 dwt. The ore occurs in shoots in a defined channel of slate running nearly north and south, and dipping to the east. The shoots pitch north into the hill in depth, and were followed until either the ore gave out or the continuation of the shoot was lost. From the appearance of the workings it will be seen that development work has been confined to the limits of the different ore-shoots, and there still remains a large extent of virgin ground to the north of the old Welcome and to the south of the Fiery Cross workings. The Eureka incline was sunk in the hanging-wall, with the intention of striking the Welcome ore-shoot as it dipped out of their ground as held at the time. However, the shoot had ceased to be payable 200 ft. above the Eureka level, and in the No. 10 level, 246 ft. below, has not been picked up, though the ground has been pretty thoroughly cross-cut at that depth. Nearly all the workings in the Welcome, except the Eureka incline and level, were caved. Operations in No. 10 level were impracticable, owing to lack of ventilation, and an attempt to reopen from the lower workings upward was also unsuccessful. Attention is now being given to prospecting the untouched ground to the north of the Welcome workings, operating through No. 5 level, and opening the ground between the Welcome and Fiery Cross through a cross-cut from the Eureka level. The latter development has not yet reached the line of reef. The No. 5 level has been reopened, and 18 in. of ore picked up beyond the former workings. There has been no time as yet to ascertain its extent. Work has been entirely confined to the Welcome Company's claims, and is as follows : Drifting on vein, 204 ft. ; cross-cutting, 292 ft.; reopened old drifts and winzes, 1,218 ft. : total, 1,714 ft. There is a twenty-five-stamp mill belonging to the Fiery Cross, which could be used on any ores developed for some time to come. The other four claims carry the Welcome line of reef for a distance of a mile and a half, and, should the ground now being opened continue to develop as it has begun, a large extent of country will be available from which the ore may be extracted without being hampered by old workings. Caledonia and Bosebery are situated at Larry's Creek, about seven miles by pack-track from Capleston. They are each special claims of 100 acres. No work has been done on the properties pending the completion of a wagon-road now about to be constructed. When, however, it is possible to haul in machinery with which to prospect this ground there is ample reason for doing so. Access to the lower workings cannot be gained, as the mine is full of water, but they are limited in extent, and have by no means prospected the ground. The property was worked to a depth of' 200 ft. at one point, when operations, it is said, were interrupted by the creek breaking through into the stopes. The yield of 6,209 oz. gold for 8,080 tons of ore, and the extensive mineralisation of the belt of country-rock carrying the shoots, are inducements for further investigation as soon as the conditions for working will permit. Ample water rights have been secured, and timber for mining is abundant. Keep It Dark Mine (Area, 56 acres 1 rood 34 perches). —This mine has been profitably worked during the year. The block of ground opened from the inside shaft continued to yield steady returns. The present workings are 1,240 ft. below the outcrop of the reef, 950 ft. below the Inangahua Eiver, and 300 ft. below sea-level. The reef averages 15 ft. in width, and 2,559 tons of quartz yielded 2,264 oz. of gold. Thirty-eight men were employed. The mine is worked from a shaft which is 503 ft. deep to No. 3 level. An inside shaft was then sunk to a further depth from No. 3 to No. 7 level of 505 ft., making a total depth of 1,008 ft. from the brace. The No. 7 level is at the greatest depth yet attained in this district. The winding machinery is worked by water-power, a large overshot wheel being used. There is, however, a steam-engine of 12-horse power, which can be used for winding if required. The battery consists of twenty stamps with three berdans, and is driven by water-power. There is also an air-compressor driven by water-power. The water-race is 140 chains in length, 6 ft. wide, and 1 ft. 6 in. in depth. The following extracts from the report furnished by the directors at the annual meeting held on the 21st December, 1896, give a full description of the mine and workings : — " Stoping out stone has been carried on between No. 6 and No. 5 levels, and the top stope is now up to within 23 ft. of No. 5 level. For the last three or four stopes the reef has been gradually making into the hanging-wall. The principal part of the reef is now about 30 ft. into the wall from the perpendicular of No. 5 level, so that there is every likelihood of the reef living up a long way above No. 5. The quality of the stone which was taken from the bottom of No. 6 level is being fully maintained, last month's crushing being the best average yield we have had. A winze has been sunk on the reef from No. 6 level to a depth of 125 ft. The winze for a short distance from the bottom appeared to be on the end of the block, but at the bottom a short drive exposed the stone, carrying payable gold. The inside winding-shaft is now being sunk by contract, and is down 84 ft. from No. 6 chamber. The rock is very hard, consequently the progress of sinking is slow. When it is down the required depth a drive of 180 ft. in length will connect with bottom of winze, and No. 7 level will then be opened up ready for stoping. The work in the mine for the year has 16—C. 3.

been greatly retarded, and much increased expenditure caused, by the heavy landslip which occurred during the heavy rains in April last. Thousands of tons of debris came down close alongside of the main shaft, smashing the poppet-heads, carrying away the blacksmith's shop and a quantity of tools, and completely destroying all the winding gear. The new winding water-wheel (which was just finished) was also totally destroyed, and the mine for some time was in imminent danger of being flooded. The Hercules Company very kindly allowed the directors the use of their windingwheel, and as soon as a connection was made with wire rope it sufficed to keep the water from rising in the mine until an engine was procured and placed on the ground. New poppet-heads have been erected, and a great amount of extra work had to be done before the mine was got into working-order. The excavation for new water-wheel is completed, and the erection of windingwheel will be at once proceeded with, as it is much cheaper winding with water- than with steampower. A new battery paddock will have to be put up, and also some repairs will be required at head of water-race ; otherwise everything is in good order. The mine at the present time, for permanency, is looking as well as ever it did, and the battery is proving the stone now being obtained to be superior in quality to what it was on higher levels. The winze which has been sunk from No. 6 level proves payable stone to exist at a depth from the surface of 1,260 ft." Hercules. —There have been no returns from this mine during the year. Keep It Dark No. 2 Mine (Area, 50 acres). —Work is not being vigorously carried on. The shaft is 470 ft. in depth, with steam winding machinery. Four men were employed at the time of my visit, but no returns of gold have been received. Golden Treasure Mine (Area, 69 acres). —There are several reefs and blocks of stone running through the ground from 2 ft. to 20 ft. in thickness. None of them have been worked at a greater depth than 300 ft. from the surface. In the south portion of the mine known as the Band of Hope there is a reef which has been worked down 250 ft. from the surface. 108 ft. has been driven on the stone, which is still showing in the face of the drive. There is a winze sunk on the stone from the level 150 ft. At 70 ft. down a drive was put north on the stone, which averaged 6 ft. to 8 ft, in thickness. If this winze were connected with the main shaft it would give 150 ft. of backs to work up. North of the above there is an antimony block of stone on which 100 ft. has been driven. It averages at least 5 ft. in thickness, and contains from 30 to 50 per cent, of antimony. By crushing this stone and running it over blankets it yielded 5 dwt. of gold per ton, and a sample of 5 tons sent to Freiberg gave a return of £23 per ton. There is a very large quantity of this ore opened up and in sight, with gold showing through it, but on account of the heavy sulphide of antimony the gold cannot be saved by the ordinary battery process adopted on this field. To the north of the antimony reef there is another reef 2 ft. to 3 ft. in thickness, which yielded 2 oz. to 3 oz. of gold to the ton. This stone has been worked some distance from the surface. The level of the bottom of the shaft is 100 ft. deeper, and this stone was never cut in it, and no prospecting done to discover it, through want of funds. The northern workings of the mine known as the Westland carry a reef which averages 4 ft. in thickness. A quantity of this stone was crushed, which yielded a value of £2 per ton. The quantity of stone crushed from the mine was 10,053 tons, which yielded 6,149 oz. gold, valued at £24,400. The stone crushed was mixed with large quantities of antimonyore and amalgamated by the ordinary battery process, which saved a very small percentage of the gold. A 25-horse-power winding-engine and boiler is employed ; and a fifteen-stamp battery and two berdans is driven by a 20-horse-power engine and boiler. Murray Creek. Inglewood Extended Mine (Area, 78 acres). — This area includes the mines formerly held by the Inglewood and the Phoenix Companies, with additional ground, joining on to the Golden Fleece and Victoria Mines. In order to bring the mine into profit the lower tunnel already driven 1,500 ft. requires extending 600 ft. to cut other lodes known to exist on the surface and in the upper workings. The proprietor is negotiating for capital to do this work, as well as to sink a shaft below the lowest adit. The Inglewood reef has been worked down from the surface 350 ft., and the Phcenix reef 150 ft from the surface, both reefs producing payable quartz. Another reef in the area, called the North Star reef, was worked down about 70 ft. Very little work has been carried on during the year, two men only being employed. Painkiller District. Dillon Extended Mine (Area, 60 acres). —The reefs in this mine vary from 18 in. to 4 ft. in width. 90 tons of quartz yielded 52 oz. of gold. Four men were employed. Merrijigs District. The Sir Francis Drake Mine has been worked chiefly in the upper or surface blocks. A crushing of 115 tons of quartz yielded 447 oz. of gold, and 60 tons of concentrates were treated for 19 oz. of gold. Seven men were employed. Al and Golden Lead Mines have both been worked on tribute. A crushing of 482 tons of quartz yielded 295 oz. of gold. Five tributers were employed. Cumberland Mine (Area, 90 acres). —This mine is worked from a shaft 531 ft. in depth, with steam winding machinery. The reef is from 3 ft. to 18 ft. in width. Six wages-men were employed for nine months, and afterwards for three months, as tributers. A crushing of 125 tons of quartz yielded 128 oz. of gold ; value, £527 Is. Prospecting was carried on in the Exchange and other claims, but no returns of gold have been received. Inkerman Combined Company's Mine (Area, 206 acres 2 roods 21 perches).—The principal work done in this mine is sinking a main shaft and driving a low level from the Rainy Creek side

of the range. Rock-drills are used, and good progress is made with them. The tunnel is in some 300 ft., and when completed should enable the company to cut the old line of reef, which some years ago yielded 9 dwt. to the ton, and tests subsequently made showed that nearly three times that quantity was lost in the battery. The main shaft has been sunk a further 100 ft., and driving has been commenced therefrom to meet the tunnel coming from the other side. At this level the shoot of stone which was worked out by the late company in the upper levels and left underfoot should be met with. About thirty men are employed. Big Biver Mine (Area, 38 acres). —The main shaft was sunk to a depth of 150 ft., and 200 ft. of driving has been done during the year. A reef discovered on the surface has been opened up, and 200 ft. of driving has been done to intersect the same, and a winze has been sunk 70 ft. on the stone. A 16-horse-power Eobey boiler and winding-engine is in use, and a water-power winding-wheel is also available. A ten-head stamper battery and six berdans, driven by a Pelton wheel, have been erected. During the year 2,000 tons of quartz were crushed, the yield from which, by amalgamation, was 1,903 oz. Twenty-eight men are employed. Lord Edward Mine (Area, 16 acres). —The shaft from which the mine is worked is 450 ft. in depth. Three levels are opened up at 200 ft., 420 ft., and 540 ft. At the latter level a tunnel is being driven a distance of 500 ft. Five men are employed. Grey District. Blackball Sub-district. Minerva Mine (Area, 96 acres). —This mine is situated at Blackball, Grey Valley. An incline drive has been put in on the reef, which is about 5 ft. in thickness. The drive is 376 ft. in length, and only a narrow strip of quartz along the drive has been taken out.. There is a ten-stamp mill on the claim, driven by water-power. No crushing was done during the year. The quartz is said to be of low grade, and so far has not proved payable. Two men were employed at the time I visited the mine. Garden Gully Mine (Area, 95 acres). —Mr. G. Perotti, who holds the mine on behalf of the Garden Gully Gold-mining Company, gives the following account of the workings : —■ The three auriferous lodes trend north and south, and stand parallel to and within 600 ft. of one another. They have been traced a distance of over 1,000 ft. along the surface. At the surface two of the reefs give prospects that may prove payable, and in one instance very rich stone was obtained. Nothing can be said of their permanency, because very little work has been done yet, owing to the fact that they were discovered only lately. On one lode a tunnel was driven to intersect it at a depth of 100 ft. The formation was cross-cut in the tunnel, but was quite mullocky, consisting of pug, slate, and quartz veins, but not containing payable gold. The claim is situate on a spur of the Paparoa Eange, leading to Garden Gully Creek, in Moonlight watershed, and at the head of Black Ball Creek. The following claims are working on the Paparoa Eange, in this locality : Imperial, Sunlight, Golden Crown, Midland, Alpha, and Eeward. In the Grcesus, in which five men were working when I was in this district, a winze had been sunk 70 ft. on a gold-bearing reef 2 ft. 6 in. in thickness. A drive was put in 8 ft. to the eastward of the reef, and a leader 6 in. in thickness was cut showing gold freely. On that portion of the Paparoa Eange known as Langdon's a number of special claims have been taken up. The field is not new, large sums of money having been spent in the locality years ago, but nothing payable was then found. Curtis Brothers, the owners of the Victory Mine, have continued stoping in No. 1 level, and have six men employed. They have been sinking a winze in the.same level, and have reached a depth of 93 ft. They have also driven a distance of 260 ft. in low level to cut the reef. The number of tons of quartz crushed has been 226, and the yield of gold from the same has been 624 oz. In the Julian Claim the owners have crushed 12| tons of stone, yielding 1 oz. 5| dwt. to the ton. Eoss District. Prospecting has been carried on in the Captain Eussell Claim by Zala and party, and 900 lb. of quartz yielded at the rate of 15 dwt. per ton. The same party also took a parcel of 12 tons of quartz from the United Helvetia, which was treated for 8 oz. of gold. Prospecting was also carried on in the Helvetia by the same party. Cedar Creek. Alpha Special Claim (Area, 100 acres). —This claim comprises the old William Tell, Eepubhc, Larnach, and other claims. The present owners, the Alpha Special Claim Syndicate (Limited), found rich stone on the surface, but after driving 223 ft. the stone became poor. It was then cut 28 ft. below the outcrop and a winze sunk 26 ft., carrying- stone all the way, until the work was stopped on account of water. One ton of quartz yielded 4 oz. 2 dwt.; value, £16 Bs. Nine men were employed. It is proposed to erect a battery of five stamps to thoroughly test the stone before putting up a larger battery. Battery Eeturns. The following statement, compiled from the monthly returns furnished by owners of quartzcrushing machines under section 308 of "The Mining Act, 1891," shows the quantity of stone crushed and the yield of gold from the various mines for year ending the 31st March, 1897 : —

This falling-off is in a great measure due to the nature of the work carried on, especially in the mines taken over by the Consolidated Goldfields of New Zealand (Limited). Operations in those mines have been chiefly towards opening up the reefs by sinking shafts and driving long tunnels and levels ; consequently, attention could not be directed to mining quartz and keeping the batteries employed. There is every reason to hope that when the new plant for treating quartz is completed no difficulty will arise to prevent this company's battery of forty stamps from being continuously employed, thus improving the future yield from the mines. Any addition to the yield of gold cannot for a considerable period be expected from the newer claims at the Paparoa and Victoria Eanges, as, even after they are proved to contain valuable ores, the introduction and erection of machinery suitable for the treatment of quartz will be costly, and much time must elapse before the recovery of gold will take place. In the other mines the new works to be undertaken consequent on the introduction of fresh capital can scarcely be expected to effect any marked improvement in the yield until after development works are carried out. The future outlook in quartz-mining throughout the district is of a hopeful nature. The mines are to be opened in a systematic manner, and provision made to provide reserves of quartz, in order that dependence need not be placed on any one particular block, but all parts of the workings be made to produce their quota of ore to keep the mills going with profit. The peculiar formation of the reefs, in which occur blank portions containing neither quartz nor gold, points to the necessity of a system of mining being adopted to keep prospecting works always in advance of immediate ore reserves. Otago District. In this district there is a considerable amount of attention being directed to quartz-mining, and the returns from several of the mines are of a highly profitable nature. It will be noticed from the following lists of special claims and licensed holdings taken up throughout Otago that greater interest is now being evinced, and that more energy is being shown, in this branch of the mining industry than in late years. The introduction of outside capital is leading to more systematic operations being carried on in opening up the mines, and, should development of the reefs show that improved processes for gold-saving are warranted, extensive improvements will be made in the necessary appliances for better extraction.

Macetown District. The Glenrock Consolidated Mine (area, 53 acres) comprises the Premier section, which is worked from an incline-adit 2,000 ft. in length with a grade of 1 in 4, from an intermediate level 180 ft. above, and also from another level below the adit. The lode is in mica-schist rock. The gold occurs in shoots of quartz, the rest of the lode fissure being filled with decomposed slate. Mr. Stanford, the general manager, gives the following account of the workings in the mine, the plant, and yield'of gold, &c.: — Only one shoot has been discovered in this mine of any permanence. This underlies with the reef, and has a pitch westwards on the strike of the reef of lin 4. It was traced from the outcrop to a depth of about 30ft. below low-level adit, where it faulted. The year's work up to November, 1896, was devoted to prospecting, and gold was again struck, but it is doubtful if it is the same shoot or a new make. The lode has an underlie of 62J degrees south-west, and strikes 26 degrees north of west and south of east. The hauling is done by electricity. Power is obtained off the mill shaft and transmitted 830 yards to a motor, which is 530 yards from the mouth of the tunnel; 20-horse power is available, but only 6 to 8 used, hauling 2 ton up lin 4 at 90 ft. per minute. Thirty stamps, in two separate mills of twenty and ten, are available. The twenty-stamp mill has 600 lb. stamps, the ten-stamp mill 800 lb. There are also two berdans and one Blake Marsden stone-crusher. Power is obtained from a 6ft. Pelton, working under 560 ft. pressure. The cyanide plant of four vats is capable of treating 5 tons concentrates per day. Twenty stamps worked 3 days 1 hour; fifteen stamps, 48 days 14 hours; ten stamps, 12 days 19 hours. About 1,038 tons was crushed, yielding 398 oz. 2 dwt. lgr. gold, value £1,596 17s. 6d.; and 19 tons concentrates treated by cyanide process yielded £69 14s. The cost of mining the quartz is only 17s. 5d., and of milling 4s. 4d. per ton. On the average sixteen men were employed. We

lost the shoot in this mine that had been traced without a break in January, 1896, just after we started sinking below our low-level adit. The shoot faulted on a cross-course, and all endeavours to trace it failed. As the line of reef did not fault, we continued sinking the incline on the reef on an even grade of 1 in 4. In May, 1896, we struck a little gold in driving, but further driving on this gold, and a rise put upon it, failed to disclose anything of value. Prom the top of the rise 25 ft. above the incline we put in a long cross-cut 70 ft. in length, following a cross-course the whole way, which led to a new line of reef, but no gold was discovered. The rise was abandoned and the incline continued. In October, however, there was a large fall from this abandoned rise, exposing a large body of ore. This was at once attacked and stoped out, and in order to get filling for these stopes the walls of the 70 ft. cross-cut were broken down, when another reef and large body of ore was exposed on the west wall. The May, 1896, prospecting works just missed these bodies by about 2 ft., and pure luck afterwards exposed them. The mine promises very well at present. The Gallant Tipperary Mine (Area, 47 acres). —This mine has been protected, therefore no work is recorded. Farrell's Claim is also held under protection for the purpose of flotation. Sunrise Mine (Area, 56 acres). —This mine, which is situated at Advance Peak, at an altitude of 5,000 ft. above sea-level, is the property of the Glenrock Consolidated Company. The ground has been prospected by driving the low-level tunnel and prospecting near the old workings. The rock consists of broken schist country, and the quartz is found in broken blocks of rusty compact stone, very rich in some places but worthless in others. In extending the low-level tunnel and prospecting in old workings for gold one good block was struck during the year. A sample of 30 lb. yielded by amalgamation at the rate of 11 oz. per ton, but 4 tons crushed only yielded 1 oz. 3 dwt. gold. This mine can only be worked during the summer months —November to May—on account of its great altitude. The peak is covered with deep snow from June to November. Developments promise well, but a new adit is wanted at a much lower level to enable operations to be carried on all the year round. Four men were employed. Tipperary Mine (Area, 105 acres). —This mine is owned by the Westralia and New Zealand Gold Explorers (Limited), and is situated in the Shotover district. It is opened up by a cross-cut adit 1,930 ft. in length. The reef, after being cut, has been driven on a distance of 490 ft. The reef is in mica-schist rock, and averages 4 ft. in width, with an underlie of 68 degrees, and strike of about 18 degrees north of west and south of east. Low-level adit struck lode on the 11th February, 1896, and since then 270 ft. has been driven west on reef and 220 ft. east; also connected with an unwatered old workings 62 ft. above low-level adit. The gold only occurs in narrow shoots or blocks of quartz. The shoot now being worked is 60 ft. in length and from 1 ft. to 8 ft. in thickness, and has been opened up through the whole of the distance between the two adit-levels. It has no pitch, but runs vertically, with the underlie through the lode. Except for these occasional shoots the rest of the lode is barren. Ten-stamp gravitation mill, 650 lb. stamps, recently replaced by new stems and tappets, American principle, giving 7501b. stamps; power, Whitelaw turbine, driven by water, about three heads and 70 ft. fall, giving about sixty-eight to seventy blows per minute, and crushing 1-3 tons per stamp per day. When sufficient quartz is available, ten stamps are used. At the 31st March, 1897, 1,234 tons crushed produced 369 oz. 11 dwt.; value, £1,490 13s. 9d. The gold is caught on copper-plates immediately outside the mill, and then on a 24 ft. by 12 ft. blanket-table. The blanketings are passed through a berdan. Fourteen shillings per ton is the cost of mining, and the cost of crushing is 4s. per ton. All wages-men are employed, the number being variable, never less than six nor more than thirty, depending on gold and funds available. This company has been recently reconstructed in London, and the name changed from the Tipperary Gold-mine (Limited) to the above. The new company is formed with a capital of £52,501 155., divided into 210,007 shares of ss. each, each share being credited with 3s. paid up, having a liability of 25., of which 6d. has been called up to date. The new company was registered in London on the Ist January, 1896. Nothing of value was struck in this mine until October, 1896, when the shoot of stone at present being worked was struck in the No. 7 level, the lowest level of the old 1887 workings, 62 ft. above our new low-level adit. A crushing at the end of October, 1896, of 101 tons yielded 60 oz. 17 dwt. bar bullion, but since then the results have been most disappointing, the yield in bulk being only 5 dwt. to 7 dwt. per ton. There are now, however, signs of an improvement, the quartz coming to hand being worth about 11 dwt. per ton. There is still about 1,000 tons of quartz unstoped above our adit-level. We are shortly preparing to sink with a small pit-engine below the level. During the year two new water-races have been cut in, one 500 yards in length to assist the turbine water, and one 200 yards in length to supply water for .the plates and blankets. At the mill the old shanks and discs have been replaced with new and heavier ones, and an amalgamating-barrel and shaking-table have been put in to assist the berdan with the blanketings. A reverberatory roasting-furnace capable of treating 1 ton per day has been erected at a cost of £145, and a small cyanide plant capable of treating 5 tons in six days has been added to the mill plant, to treat the blanketings after having passed them through the berdan or barrel. The pyritical sand is heavily charged with arsenic, and is valued at from £7 to £8 per ton. Treatment was started in April, and at first was not at all successful, the first run of 22 tons only giving 51 per cent, extraction, and the second run of 15J tons giving a 73-per-cent. extraction. After several modifications in the method of treatment complete success has been obtained, and we are now obtaining 100-per-cent. extractions by a combination of cyanide and amalgamation. After roasting the mercury would not touch the gold, though apparently free, and visible to the naked eye in the pan. Cyanide treatment only gave low extractions, but after cyaniding the residue was passed through the mill and the gold was then found to amalgamate freely. It takes a little over half a cord of wood to roast 1 ton, and costs £1 15s. without labour. Mr. Walter Stanford, the general manager, supplied the above information.

Achilles Mine (Area, 125 acres). —This mine is situated at Bullendale, near the head of Skipper's Creek, on the western slopes of Mount Aurum, from which emerge the richest goldbearing streams in New Zealand. From the bottom of the shaft, which is 150 ft. deep, starts No. 2 level, with which the lower levels are connected by a perfectly true grade. Up this grade the quartz is hauled in trucks by an engine worked by compressed air, the trucks containing 5 cwt. each, and is sent to the surface, where the quartz is emptied into self-delivering paddocks, whence it goes in trucks holding 25 cwt. to the battery, where all the fine stuff is sifted out on grizzlies, the coarse lumps being reduced by rock-breakers; thence it passes into automatic feeders, which pay the quartz, now reduced to a uniform size, into the mortar-boxes. The automatic feeders have now been in use for twenty-five years, and have given perfect satisfaction. Thus the quartz is conveyed from the face of the mine where it was first broken out to the battery without being handled oftener than at the initial filling into the first trucks. At No. 2 level the lines of lodes have converged so much that they are only 105 ft. apart, so that the work of looking for any missing portion is reduced to one-half of what it was at the low-level adit, 120 ft. above No. 2 level. Now, to carry out the argument: At No. 4 level, 184 ft. below No. 2 level, the distance is only 68 ft. between the converging lodes, and in place of the middle lode, which has so far not been located at this level, there is a body of phyllitic rock that carries payable gold for a distance that has not yet been correctly defined. If the three lines of lodes continue to converge at the same ratio they will unite at a level about 90 ft. below No. 5 level. The present exploitations in the Achilles Mine are chiefly confined to No. 5 level, and are of so encouraging a nature that the chief energies of the management and plant are directed to their development. As stated, this level has reached the depth of 1,200 ft. below the highest outcrop of the lode on the hill sideling above it. It is connected by two winzes 160 ft. apart with No. 2 level, which in its turn is connected with the surface by the present vertical working-shaft 150 ft. deep. A grade already spoken of leads down from No. 2 to No. 5 level, and is fitted with a double line of rails for the ascending and descending trucks. These connections provide the most perfect ventilation that could be desired, as well as all the other necessary conveniences of access, so that it may be pronounced to be in full working-order. The two winzes are in course of being connected. The stone now being attacked had a width of 7 ft. at No. 4 level; but at a depth of 83ft.-- that is, at No. 5 level—it had widened out to 13ft., the whole of which is sent to the mill. The new shaft, when completed, will be 600 ft. deep from the surface to the bottom of the mine, and will give every convenience in the future working of the mine. It will be 12 ft. by 4 ft., divided into three compartments of 4 ft. by 4 ft. each in the clear. The Achilles stone has been pretty free from pyrites so far, but as greater depths are reached they are increasing in quantity, and may be found to be impregnated with gold when still greater depths are reached. The new race from the left-hand branch of Skipper's Creek will give 400 ft. of pressure, and will be applied directly, instead of employing it for the purpose of generating electric power, as is done at present. The new race is nearing completion, and is expected to be available for motive-power before winter. It will have the effect of very considerably reducing the working-expenses, and will insure a greater degree of efficiency in the work done. The race will be applied to a Pelton wheel, and the present air-compressor at the shaft may be done away with. Hauling and pumping will then be directly done from the mouth of the shaft. The electric power will be held in reserve for the extremes of weather and other emergencies. The Achilles Goldfields Company was registered in 1893, and up to the present date 7,181 oz. of gold have been produced, valued at £27,500. Out of the time of its existence there must be deducted eight months during which repairs were carried on. During the year 5,453 tons of stone was crushed, giving a return by amalgamation of 4,413 oz. Seventy men were employed. Cornubia Mine, Skipper's Creek (Area, 30 acres). —No work was carried on during the year, owing to liens registered in Court, and the men cannot now be found. Mr. F. Evans, the owner of the miue, says, " This is an instance of the easy manner in which miners can close up a claim. I have dealt with all liens of those men who could be got at, but others cannot be got at, and I cannot see any way that the claim can be relieved." Leviathan Mine. —This claim is situated near the Shotover Eiver. The outcrop of the quartz is 1,000 ft. above the Shotover. Another reef is located on the opposite side, higher up the gully. An adit has been driven 350 ft. to cut the Crystal reef. No record has been sent in of any crushing from this mine for the year. The Sandhills Claim, of 20 acres, has been lately taken up, and is now under protection. Lawrence Brothers' Mine, Bannockburn. —Operations are still steadily conducted in this mine; 876 tons of stone was crushed, for a return of 346 oz. of gold, valued at £3 17s. per ounce. Five men were employed. Cromwell Mine, Bendigo (Area, 137 acres). —Three levels were opened ; depths, 115 ft., 420 ft., 520 ft. A leader lode, varying from Ift. to 4 ft. wide, composed of clay, slate, and quartz, enclosed within hard walls, was discovered. Driving levels and stoping; nearly the whole work was done for prospecting. The pumping and winding machinery is driven by water-power ; 30-horse power in use. The battery of twenty stamps is driven by water; 10-horse power in use. The aircompressor and rock-drills are not in use. The stamps weigh 7 cwt.; and there are four berdans, but only one was used during last year. During the year 650 tons of stone was crushed, yielding 262 oz. of gold. Twenty men were employed. McCabe and Sons' Mine. —During the last twelve months the owners have been driving a tunnel on a line of reef on the Carrick Eange, about four miles from Bannockburn, known as the Young Australian, which yielded good returns about twenty years ago, but was abandoned at that time through meeting with a large quantity of water. The level now being put in is 90 ft. below old workings, and the lode underlies 3 ft. in 1 ft. This will give about 270 ft. of backs. The level is in 300 ft., and it is expected to cut the reef in 300 ft. more. A small mill of two stamps and Pelton wheel is sufficient to deal with 21 tons of quartz per week. The cost of driving the tunnel is about £1 per foot. Two men are employed.

Invincible Mine, Earnslaw (Area, 75 acres). —A considerable amount of work has been done in this mine in development work, and a body of quartz 70ft. by 13ft. is exposed. A cyanide plant has been erected, which is kept employed on the tailings accumulated in former years. The mill, which is not at present in use, includes a ten-stamp battery, 8001b., seven 4 ft. 6 in. berdan pans, one octagonal iron amalgamating-barrel, one shaking-table; cyanide plant consists of one solution-tank, two 25-ton leaching-vats, two extractors, and two sumps. Mill driven by an overshot water-wheel. Six men are employed at the mine and four at the cyanide plant. White's Beef (Area, 28 acres.) —This mine, which is situated at the Old Man Eange, has been steadily worked. The reef varies from 6 in. to 2 ft. The pa.rty own a five-stamp battery, driven by water. 236 tons of quartz yielded 270 oz. of gold. Six men were employed. Excelsior Mine (Area, 100 acres). —This mine is situated on the Old Man Range, near Bald Hill Flat, about 3,000 ft. above sea-level. The shaft has been sunk to a depth of 60 ft., and an adit driven to connect with it 350 ft. in length. The lode is a large body 20 ft. in width, carrying more or less gold throughout, but principally on the two walls. The owner, Mr. F. W. Gray, has a battery of three stamps, driven by water-power. Four men were employed. The property has been placed under option to the New Zealand Minerals Company, who are doing development work, with fair prospects. Bonanza Quartz-mine, Macrae's Flat (Area, 60 acres). —Three levels have been opened—at 200 ft., 350 ft., and 500 ft. from the surface. The reef varies from 2ft. to Bft. in thickness, the quartz being of a rubbly nature. Two shoots of stone about 400 ft. apart are being worked on. The crushing machinery consists of a Huntington roller-mill, one Dodge rock-breaker, and one Price's pan, all driven by a Pelton wheel. During the year 232 tons of stone was treated, for a return of 219 oz. 12 dwt. Eight men were employed. Golden Point Mine, Macrae's Flat (Area, 67 acres). —This claim is worked both as an alluvial and quartz claim. The surface consists of peaty soil, with gravel-wash containing boulders, and is ground sluiced by \\ heads of water under a pressure of 70 ft. A quartz reef varying from 3 ft. to 6 ft. in width is also worked. The battery consists of ten stamps, one 5 ft. roller-mill, one rockbreaker, and two 3 ft. 6 in. grinding-pans driven by a 6 ft. Pelton wheel giving 30-horse power; 300 tons of stone yielded 63 oz. 12 dwt. of gold. Six men were employed. Barewood District. —The Barewood Quartz-mining Company's properties are now worked by the Anglo-Continental Syndicate, who hold the option of purchase. The reef has been traced two miles and a half, and the company intend to sink two shafts about half a mile apart. It is also intended to drive a long tunnel from the Taieri Valley to drain the country and enable prospecting works to be carried on at a greater depth than has been hitherto practicable on account of the expense of sinking, for which large capital was necessary. During the year 1,192 tons of quartz was treated, for a return of 715 oz. 2 dwt. of gold. Caledonian Mine (Area, 205 acres ; owners, — Orr, H. Piper, Charles Stewart, D. G. Simpson, — Youll, T. C. Simpson).—The land was prospected by trenching and sinking in different places. The reef was discovered on Sections 3, 4, 5, 6, 7, about 3 ft. 6 in. in width, but work has not been commenced. The owners are providing £100 for prospecting purposes in the meantime, and will make further calls of £100 from time to time to continue operations, and if sufficient inducement can then be shown the property will be disposed of in England. Nenthorn. Golden Band Mine, Nenthorn (Area, 60 acres). —A shaft has been sunk 60ft. and an adit put in 200 ft. The reef averages 5 ft. 6in. between the walls. A battery of five stamps, each of Bcwt., is driven by water-power. During the year 200 tons of stone was crushed, for a return of £280. Four to six men were employed. The option for flotation of this mine was acquired by a London company twelve months ago. Six months ago it was reported to be sold, but as yet the negotiations have not been completed. This has meantime prevented the working of the mine in a proper manner, as it requires the expenditure of a large sum to open it out at a lower level. It also requires suitable gold-saving plant, as owing to the fineness of the gold and pyritic nature of the stone about 50 per cent, of the gold is lost by the usual method of amalgamation. Prospecting operations have been carried on in several other claims in this district, but no returns have been recorded. Preservation Inlet. The attention of miners is being yearly more directed to the Preservation Inlet district, and there is every indication that in the near future a prosperous mining field will be opened up. As it was impossible for me to visit the district, I am indebted to a gentleman of considerable mining experience who was on the ground during the year for the following particulars. A considerable revival has taken place here owing to the rich quartz found in the Morning Star property, the mine at the present time employing upwards of seventy men. There is now a large settlement, with two stores and a post-office, at what was known as Long Beach, now Te Oneroa. The Morning Star Gold-mining Company's mine, at Te Oneroa, is still continuing to return satisfactory dividends to the shareholders, the total yield of gold since the commencement of operations being valued at some £20,000. The returns for the year ending the 31st March show that 3,140 tons of stone was crushed, for a yield of 3,420 oz. 14 dwt. of gold, valued at £4 2s. per ounce. The quality of the gold won is of high character, the assay returns from the Melbourne Mint showing a grade of over 23 carats. Ten new berdans have been erected during the year, and the mine machinery generally is in excellent order. The wharf, on which a Government subsidy of £120 has been received, is now completed, giving a depth at low water of 15 ft., thus affording greater facilities for the reception of coal-steamers. The Alpha Gold-mining Company has been formed to work what has been known as the Longney's Claim. There are several outcrops of quartz on the property, from some of which very fair prospects have been obtained, but for the past year little work has been done. 17—C. 3.

In the Golden Site Extended Gold-mining Company's mine, at Wilson River (area, 144 acres 1 rood 18 perches), cross-cuts have been driven to the eastward 105 ft. and 52 ft., and a tunnel driven on the line of reef. It was decided subsequently to put down a shaft 12 ft. 6 in. by 4 ft., and the required machinery will be erected. A well-defined reef has been traced a considerable distance on the company's property, from a trial crushing a sample of which gave favourable returns. On the north side the Crown, Lizard, and St. George Claims are under protection. On the coast-line claims have been taken up on which strong outcrops of quartz have been discovered, but little or no development work has yet been done. At Isthmus Sound the stone taken from what is known as Bradshaw's reef is highly mineralised, containing copper-pyrites, mispickel, zinc-blende, and galena, with a varying proportion of gold and silver. It is proposed to ship a parcel of ore Home for treatment. Several other claims have been taken up adjoining the Prospectors', but as yet little work has been done on them. It is worthy of note that Bradshaw's reef occurs in gneissic rock, all the other reefs prospected being in similar formation to that of the Morning Star and Golden Site—viz., Silurian slates and sandstones. Only a few men are employed in alluvial mining, centred chiefly at Coal Island and at Gulches Head, at the Neck. It is not believed that their earnings exceed a bare living.
Summary of Returns from Quartz-mines from the 1st April, 1896, to the 31st March, 1897.
Tailings treated : Glenrock Consolidated Company, Macetown, 19 tons ; gold obtained, value £69 14s. The foregoing summary of returns from the different mines shows that 15,450 tons of quartz was crushed, yielding 10,247 oz. 18 dwt., having a value of about £40,000. The Achilles Company and the Morning Star Company have turned out quartz of a highly profitable character ; and the mines at Macetown also give results showing that with increased output of quartz and the application of labour-saving machinery the ore may be also profitably dealt with. The AngloContinental Syndicate is devoting attention to the Barewood district, and no doubt have in view properties in other districts that may afford sufficient inducement for the outlay of capital for development purposes. It is also believed that other mining syndicates contemplate commencing operations in the Nenthorn, Preservation Inlet, and other districts. The prospects of quartzmining throughout Otago are decidedly improving.
ALLUVIAL MINING. Nelson District. Collingwood. The Parapara Hydraulic Sluicing Company hold an area of 415 acres, chiefly freehold, which is worked by hydraulic sluicing. Fifteen heads of water, with a pressure of 125 lb. to the square inch, have been at work on the three faces of 110 ft., 80ft, and 43 ft. respectively. During the year 200,000 cubic yards of alternate layers of clay and gravel have been treated, but the results have not been made public. Elevators will shortly be erected. Nine men are employed. The Collingwood Goldfields (Limited), an English company, hold a 200-acre lease at the Quartz Ranges which it is proposed to work by hydraulic sluicing. Mr. C. Y. Fell, the attorney for the company, gives the following report: " This property, and also a lease at Golden Gully, belong to an English company called the Collingwood Goldfields (Limited).

of-men under him, to explore and lay off a water-race to supply the nozzle from the Clarke River. This river was wholly unexplored, and the upper part of the race presented almost insurpassable difficulties. Mr. Holdsworth therefore abandoned it, and after great labour reports that he has found a practicable course for a race round Seal Hill to the Boulder Lake, about 3,200 ft. above sea-level. Immediately his plans are ready the construction of the race will be commenced by Mr. F. G. Mace, whom I have appointed manager and engineer for this purpose. So soon as Mr. Holdsworth has finished his work at Boulder Lake he will proceed to Slate River and lay off a race there to bring water to Golden Gully, which will also be taken in hand immediately the survey is finished. There will therefore very shortly be a large number of men employed on both these works." Takaka. A fair number of miners have been at work in this district, and have earned good wages. The Upper Waingaro River terraces, Bubu and Anatoki Rivers, have all been worked, but the methods employed are of a somewhat primitive character, and no extensive developments have been made. Motueka. Several applications for special claims, licensed holdings, and mineral licenses have come before the Court during the past year, but of these only one—a licensed holding of 30 acres—has been finally dealt with. It is intended to work this claim by hydraulic sluicing, the water being brought from Lake Peel. The special claims applied for embrace an area of 700 acres. The mineral licenses are to work deposits of asbestos; but progress has been delayed on account of the difficulty experienced in getting surveys made. The claims referred to above are all in the neighbourhood of the Mount Arthur table-land. A few miners have been at work on the Leslie River and about the Karamea Bend. On the Sherry, Baton, and Wangapeka Rivers a number of men are making a living, and it is reported that hydraulic sluicing on a large scale is shortly to be engaged in on Macrae's land at Wangapeka. Marlborough. There is little or nothing of importance to report on in the Marlborough District. A few men are obtaining poor wages. Special claims and licensed holdings are apparently being held for the purpose of sale. The prospects of the district, however, will be greatly improved if capital is introduced for the working of the auriferous deposits, which can only be effected on a large scale, and by considerable expenditure of capital. West Coast. Westport. The claims at Addison's and the Northern Terraces, in the vicinity of Westport, are still giving profitable returns to the miners, and apparently will continue to do so for many years to come. A large number of special claims, licensed holdings, and other mining rights have been taken up at Westport during the past year, but, beyond prospecting, little actual work has been done in connection with most of the rights. Bradshaw's Terrace. Lind and party occupy an area of 30 acres. The alluvial deposit consists of black sand and boulders. Ten chains of fluming have been erected, and ground sluicing is being carried on with eight sluice-heads of water with a3O ft. pressure. Three-quarters of an acre of land has been washed away for a return of gold value £500. The gold is saved on tables 41 ft. in width, on which there are five rows of plush. Three to six men are employed. Several other parties are at work in this locality. Addison's Flat. Maid of Erin Claim (Area, 10 acres). —Employs six men in ground-sluicing, the stones being hauled up the shaft 40 ft. by means of a water-balance of 10-horse power, and fair results have been given during the year. Golden Sand Company's Claim (Area, 308 acres). —This company expect to be at work in two or three months, and are at present constructing a water-race two miles and a quarter in length and a reservoir capable of storing 3,000,000 cubic feet of water. These works are at present under contract, and the Despatch Foundry, of Greymouth, are making the battery of twenty 5001b. stampers. The cement which is on or near the surface is from 8 ft. to 9 ft. thick, extending pretty well over the whole of the area held. The cement is easily crushed, but there are stones inseparably connected with it that must be put through the battery also. It is expected that the twenty head of stampers will put through 100 to 120 tons a day. The tables, which will have a spread of 72 ft., will be kept up Bft., so as to allow of future concentration and treatment of the tailings, as only about one-third of the gold proved by fire-assay to exist in the ore will probably be saved on the copper-plates and plush. This is owing to most of the gold being coated with a film of oxide of iron. Gould and party's Claim (Area, 15 acres). —This claim is worked by ground-sluicing, with a water-balance for lifting the stones. The amount of water which is in use in the face for carrying the dirt to the hopper is nine heads. The face of wash-dirt is about 16 ft. deep, chiefly black sand, with a moderate amount of stone m it. The hopper-plates are perforated with Jin. holes, and all the dirt which runs through these holes, together with the gold, passes down a tunnel 1,000 ft. in length to the tables, which are 50 ft. long—five tables, 2 ft. 6 in. wide, covered with plush ; then through a tunnel 7,000 ft. hi length. The ground is broken down by means of a nozzle with about
a—3
126
25 ft. of pressure. During the past year the owners have.driven 260 ft. of tunnel and erected a new water-balance, which is now in working-order. This work has been done for the purpose of working the stony lead which is on the western side of the claim. Garryoioen Mine (Area, 23 acres). —Messrs. Carmody and party. The face, which is worked by ground-sluicing, with a water-balance and trucks for taking the stones up an incline road, is about 50 ft. in depth, ten of which is black sand. Fourteen heads of water are employed. The black sand and all the finer stuff is carried through a tunnel about 3,000 ft. long. It passes over a hopper, where the stones are separated and taken in trucks of three-quarters of a ton each by a water-balance in an incline road to a height of 60 ft. The sand passes over tables 60 ft. wide by 20 ft. deep, covered with plush to save the gold, the sand passing through the remainder of the tunnel. The plush is washed in tubs, and then put into a churn-barrel with quicksilver and amalgamated. During the year 450 oz. of gold, valued at over £1,700, has been obtained by the eight shareholders at work. Venture Mine (Area, 60 acres). —The cement is obtained from open workings about 8 ft. in depth. There is an overshot wheel for driving the battery of twelve stamps of 3 cwt. each. During the year 9,231 yards crushed yielded 1 dwt. 1-J-gr. per yard by amalgamation. Five men are employed in the battery. The cost of mining and. delivery of the cement is Is. per yard. Dublin City Mine (Area, 13J acres; owned by Twohill and party).—The cement, which is 12 ft. thick, is crushed by eight heads of stampers of 3 cwt., driven by a 30 ft. overshot wheel. Some 50 tons are put through daily, at a cost of 2s. 2d. per yard. Five men are employed. ODea and party are also working a claim of ten acres of cement ground with good returns. The Golden Lead Claim, Halligan and party's claim, and Sullivan and party, as well as several other parties, are engaged sluicing in the district. At Cascade Creek several parties are engaged in sluicing, and in the Cascade Claim Patz and party are putting in a drainage-race for the purpose of lowering the water in the creek, where they expect to meet with payable wash. They also intend to erect a water-wheel for winding purposes. General Exploration Company (Limited). —This company has secured a number of mining properties in the Addison's, Charleston, and Mount Rochford districts, and is employing a large number of men. Mr. C. Dencker, the attorney for the company in the colony, reports as follows: — " We have five properties—three situated at Four-mile, near Charleston, and known as the Empress, Aurora, and Four-mile ; one in Addison's Flat, known as the Bendigo; and one at Mount Rochford, about nine miles from here, and known by that name. The first three properties above mentioned I will deal with first. These three properties have an area altogether of 259 acres, and contain large deposits of cement. The gold is very fine, and has a coating of oxide of iron, which makes amalgamation difficult. We have not commenced active operations at these claims yet, but have been, and are still, experimenting to find out the most economical method of working the cement, and we hope shortly to be in a position to place our orders for machinery. The ore is low grade, making economical working essential. The remainder of the ground we propose working by sluicing, the water for such purpose to be brought in from the Argyle Dam. The manager of the above-mentioned properties is Mr. E. G. Braddon. " The Bendigo and Rochford are both sluicing claims, the former containing 140 acres and the latter 100 acres. We have let a contract at the Bendigo for the construction of a tail-race tunnel, which, when completed, will be about a mile and a half in length. Besides this, another contract will be let shortly for widening about two miles and a quarter of the present race from the old Fairmaid Dam, constructing 26 chains of tunnelling, widening 15 chains of the present race from Reid's Creek and constructing 20 chains; also constructing a race 20 chains in length from Reid's Creek to Island Creek. Besides the above, a race is to be constructed connecting with the Nine-mile Creek, and a race from the Fair-maid Dam, which have not yet been completely surveyed. Up to the present time the Bendigo has not been worked. With reference to the latter property (Rochford), this property has been worked for a number of years by four shareholders on a very primitive scale. A contract has been let by us for raising the present dam (known as Lake Rochford) 12 ft., and constructing a race from Deep Creek to the lake. A by-wash 80 ft. in width and a race from the lake to the claim have yet to be constructed. Further races to be constructed will connect the dam with Wareatea Creek. A contract has also been let for the supply of 1,710 ft. of pipes, which will arrive here in about two months. The property shows many large boulders, which will have to be removed by machinery, and for which purpose we have just acquired a steam-crane. We are actively engaged in developing our claims, and in June or July we hope to start working operations at Rochford, and in August at Bendigo. I may mention that the tables which we are about to erect at Rochford will have a spread of about 200 ft. The manager of the Rochford and Bendigo Claims is Mr. A. G. Hill, late of the Wakamarina." Charleston. The Enterprise Claim is worked by a party which employs five men, who are engaged in cement-crushing. They have a battery of four stamps, which puts through 16 tons per day, giving satisfactory results. Birch and party's claim is worked by four men, who crush 8 tons of cement, with a four-stamp mill. Lander and Sons' claim, of 4 acres, is situated at Back Lead. This party owns a five-stamp mill, stamps 2501b. in weight each. During the year 2,340 tons of cement was crushed, for gold of the value of £2,635. Three shareholders are employed. A considerable number of men are casually engaged in sluicing, and several parties also earn a living by placing tables in the creeks below the other workings, on which it appears sufficient gold is caught to induce them to continue at this kind of work. Several parties also obtain gold by sluicing the black sand on the sea-beach.

o.—B
At the Barrytown Flat Gold-mining Company's mine extensive development works are being carried out. The manager, Mr. W. White, reports as follows: "This company, which has only recently been formed, has a 192-acre claim on Barrytown Flat. They have a right to thirty heads of water out of Baker's Creek, and a race is to be constructed for a distance of 142 chains to convey the water to the penstock at the head of the pipe-line, which is 600 ft. above the level of the ground we intend to start operations on. The greatest depth that has been reached in the claim is 20 ft., the flat being at too low a level to work deeper by the ground-sluicing system. Messrs. A. and T. Burt, of Dunedin, are supplying the plant, but none of it has arrived yet, and it will be some months before we commence elevating. The main line will be 22 in. and 18 in. pipes, and we will have branch lines of 11 in., 9 in., and 7 in. pipes. Our uptake pipes are to be 15 in., with a 7 in. throat. Ido not know what distance we will have to elevate the dirt, as the depth of the ground is not known. If we find it necessary we will sink to a depth of about 60 ft. with our first elevator, and if we do not then reach the main bottom I will, after opening out a large paddock, put in another elevator and sink deeper. The drift is a sea formation. The surface gold is very fine, and there is a great quantity of black sand with it." On the Barrytown Flat and along the beaches and flats to Razorback in a northerly direction, and to the Ten-mile Creek to the southward, about sixty miners are employed in sluicing, whilst along the terraces in the same district upwards of seventy miners are engaged in sluicing. The returns from those claims cannot be obtained. It is, however, understood that sufficient gold is recovered by the miners to give a fair average rate of wages per man. Grey Valley. Soaring Meg Alluvial Mine, Sluicing and Water-race (Area, 30 acres). —This mine is the property of the Roaring Meg Water-race and Gold-mining Company, and Mr. G. Perotti, the manager and one of the owners, supplies the following particulars : "The water-race is about two miles long, 2,000 ft. above the sea-level, supplies thirty heads of water, and has 900 ft. of pressure to the tail-race. The present ditch is only 600 vertical feet above the tail-race, but if required another ditch can be cut 300 ft. higher. It is, perhaps, the largest natural power developed in New Zealand. The alluvial face is 45 ft. high on an average, and yields about Is. 4-J-d. per cubic yard. Upon such yield the ground should pay splendidly, but so far the company has been unable to obtain profits. Three years and £6,000 have been spent in bringing the water-race in, making two tail-races (one of which is very long), and preparing the ground for extensive operations. The reason the company is unable to make it pay is because the wash consists almost of seven-eighths of stones ranging in weight from 300 lb. to 40 tons. The water has only been used for one hour out of every eight, the other seven hours are all spent in the terribly laborious work of blasting stones and carrying them away in trucks. The owners are aware that nothing but big mechanical power can turn this into a payable venture. Further capital is required to equip this claim efficiently, and the owners are now trying to arrange for this. It will be necessary to obtain 3,000 ft. of strong piping in order to utilise the pressure ; two five-ton cranes to lift the stones and heap them in the back ground, and an electric-light installation in order to enable the water to be utilised for the whole twenty-four hours of every day. It is intended to open a face 200 ft. wide, divided for two hydraulic nozzles, so that the water will have the power of playing alternately on half of the width of the face whilst the cranes do their work with the stones on the other half. When these improvements are effected no doubt the mine with prove remunerative for years to come ; but, as in most instances of gold-mining, the fact is again illustrated here that the industry is becoming most difficult and expensive, and that large outlay is required before attaining a payable development." Moonlight. —The population of this district, which includes Healey's Gully, has also increased. Along the slope of the Paparoa Mountains, from the head of Moonlight to Blackball, a large area of alluvial ground is known to exist, but the difficulty of obtaining a supply of water at a sufficiently high level to command the ground is a great drawback. At Healey's Gully the Republic Company hold a special claim of 35 acres, and has brought in a race capable of carrying forty heads of water. The prospects of this claim appear favourable, but it is not yet sufficiently developed to enable authoritative opinion to be given. About forty men are employed on the field. Granville, Duffer's, and Noble's Greeks. —There have been no new finds during the past twelve months, and the mining population remains stationary. Judging from appearances the miners seem contented and satisfied with their earnings. Some are engaged tunnelling and others sluicing. Orwell Creek. —Here also the population remains about the same, most of the miners being engaged tunnelling. The scarcity of water precludes sluicing to any extent, although it is well known that large areas of payable ground exist. Arahura District. Work has still been carried on in Boy's Claim, but, on account of having lost the face about ten months ago, very little gravel has been washed, the returns not having paid expenses. Dwyer and party are engaged in putting in a drainage-tunnel, and are receiving Government subsidy. The most important mining properties in this district were taken over, and are now worked, by the Consolidated Goldfields of New Zealand. Humphrey's Hydraulic-sluicing Company (Limited). —As much of the ground held by this company as could be investigated since its acquisition has been carefully sampled, and what water was available has, in the hands of the tributers, been used to check data obtained in other ways. The results so far obtained have shown the gravels found on the two slopes and the various
a—3
128
branches of Humphrey's Gully to be of a payable character. Work is in progress on the gravel deposits to the east, and, should a repetition of the results obtained in Humphrey's Gully be found, there need be no hesitation in starting the new equipment. Surveys are under way with the object of bringing in a race which it is expected will be less expensive in construction than the one already estimated. The tributers' desultory work resulted in obtaining 156 oz. gold, sufficient to pay all labour of prospecting outside of engineer's fee. Surveys and estimates are now being made with the idea of putting the present supply of water on better-grade gravel, so that the time occupied in surveying the large race and prospecting gravel will not be lost. Kumara. This is the most important hydraulic-sluicing district in the colony, and for many years past has produced quantities of gold, and has furnished employment to a very large number of miners, not only in the locality adjacent to the ample water-supply provided by the Government in the Waimea-Kumara Water-races, with their recently-established branch races, but also to a very large number of men in the Greenstone and other parts of the district, who, though working on a smaller scale, are yet profitably employed, and will, in all probability, for many years to come be enabled to earn a living, if not a competency. In the vicinity of Kapitea Hill, although the smaller areas of rich ground have been to a certain extent worked out, there still remains a very wide extent of country containing auriferous drifts. The later explorations in the low-level tunnels driven from the Teremakau River terrace show that profitable employment may be given to a number of miners for future years. Although the yield of gold on the Kumara field has fallen off, there is still a large quantity being obtained, and the field will yield good returns for many years to come. The area of ground on the field that will be sluiced away in the course of years is very extensive, and, although it is comparatively poor, it will, with improved and more economical methods of sluicing, employ a large number of miners. There are three main tail-races (sludge-channels) at present in work. What was originally known as No. 1 main tail-race has been abandoned for the last seven years, as it was found to be too low for the economical discharge of tailings on the tailing-site. No. 2 main tail-race has still four claims making use of it, and there is still an area of known auriferous ground that will take some years to sluice away commanded by the main tail-race. No. 3 main tail-race is used at present by ten claims, and the area of ground untouched commanded by this main tail-race will not all be sluiced away in ten years. Another party has obtained a right to sluice into No. 3, and their branch tail-race will soon be driven from the main tail-race to their claim. No. 4 main tail-race is used by three parties at present, but all of the parties are using large quantities of water —fourteen, fourteen, and twenty-four sluice-heads respectively, and they are in consequence sluicing away about twice the quantity of auriferous wash that the same number of claims washed away six years ago. Another party has driven a branch tail-race connecting No. 4 with their claim, and they will shortly begin sluicing into it. No. 5 main tail-race is not yet completed, as bad and difficult pug ground was met with in No. 1 section of the work, and the loose ground and large inflow of water was met with in No. 2 section. These difficulties have greatly retarded the progress of the work. The total length of No. 5 main tail-race will be 62f chains, and of this 40J chains has been completed, and 22-J chains has yet to be driven. No. 5 main tail-race will open up a very large area of auriferous ground, and, although the ground is not by any means rich, it will give employment to a number of miners, and enable them to earn wages for the next twenty years. The number of claims engaged in hydraulic sluicing on the Kumara field are : No. 2 main tailrace, four parties, thirteen men ; No. 3 main tail-race, ten parties, thirty-nine men ; No. 4 main tail-race, three parties, seventeen men ; private tail-races, nine parties, forty men; parties preparing to sluice, three parties, seventeen men. Of the above-mentioned parties, twenty-one are using water from the Government race and five from private races; and of the three parties preparing to work, two will use water from the Government race and one from a private race. The Kumara Long Tunnel Gold-mining Company have an alluvial claim of 60 acres at Kumara, worked by hydraulic sluicing, the length of the tunnel and tail-race being 2,742 ft. The materials treated consists of an alluvial drift of glacier wash, averaging about 40ft. in depth. The water used averages twenty Government heads, giving a pressure of 80 ft. The quantity put through during the year was 153,360 yards, yielding 625 oz. 5 dwt. 12 gr. ; value, £2,438 lis. — £975 Bs. 6d. for owners and £1,436 2s. 6d. for tributers. The quantity washed per hour is 120 yards, averaging 2 gr. of gold per yard. Waimea. The Waimea district still continues to give employment to a large number of miners, and there is a fair hope of a considerable revival when the Waimea main tail-race and the Kelly's Terrace drainage-tunnel are completed and working, and the yield of gold will compare favourably with recent years. The driving of the Waimea main tail-race has been completed throughout its whole length— about 2,100 ft.—and the trustees are about to sink a shaft at the upper end of work to connect it with the surface in the large flat in the middle branch of the Waimea Creek, where highly-payable sluicing-ground is known to exist. When this communication is made the tail-race will be paved with wood blocks, the material for which is now ready. Several parties are ready to drive branch tail-races to connect their claims with the main tail-race, when sluicing operations will be proceeded with. The large area of ground proposed to be sluiced through the main tail-race has nearly all been taken up in claims. The completion of this work and the starting of extensive sluicing operations in connection therewith should give a great impetus to mining in the district, as all the old residents have no doubt as to the payable character of the extensive flat commanded by this main tail-race.

Bimu, Back Creek, and Seddon's Terrace. The claims continue to yield good returns, and the" miners generally appear to be satisfied with their earnings. Craig's claim also is giving satisfactory returns, and the different claims on the University reserve and those extending further south are also doing well. The old beach deposit is also being worked by Mcßeth and party at the Shanghai lead. Phillips and party are working near Lake Mahinapua, where they purpose commencing dredging operations. Grimmond and party, who hold an extensive area in this locality, have in view a project of bringing in a large water-race from Lake Kanieri for working their claim and others in the vicinity. A water-supply is being brought in by means of the old Kanieri Water-race, the owners of which are working their own claims and supplying water to other parties at the Kanieri Forks. Should this race be further extended a supply of water will be available for working a large area of ground in the vicinity of the Kanieri Township. Boss. Mont dOr Gold-mining and Water-race Company (Area, 63 acres). —This mine is still steadily and profitably worked, and is one of the most consistent dividend-payers on the Coast. Operations are carried on by ground-sluicing a high terrace, sixteen sluice-heads of water, with a pressure of 240 ft., being used. The company's balance-sheet for the year ending the 30th November, 1896, shows that during that period 1,368 oz. of gold, valued at £5,335 3s. 6d., was obtained, of which amount £3,000 was paid in dividends. Boss United Gold-mining Company. —The company hold an area of 143 acres, situate at Jones's Flat. The plant and machinery used consist of reversible Peltons for winding purposes, a reaction turbine for elevating, and a 10-horse-power turbine for electric-lighting purposes. The gravel is first elevated and then drawn up an incline to the sluice-box, the water from the workings finding its way through the low-level adit formerly driven to drain the shaft. The claim is worked on the tribute system, twenty-five men being employed. No work has been carried on during the year in the shaft and deep levels. The Prince of Wales Claim, 60 acres, situate at Donaghue's Creek, is also owned by the Ross United Company. The gravel is here elevated by a dredge to the sluice-boxes, five heads of water, with a pressure of 39 lb. to the inch, being employed to drive a reaction turbine. Sixteen men are employed in this claim, which is also worked on the tribute system. Several other claims are worked with a fair degree of success by small parties throughout the district. Parties of men are employed all along the Coast to the southward, and during March a small rush set in between Lake Mapourika and Okarito Forks, where the terrace extends south-east from the Forks to McDonnell's Creek, some four miles distant. Only two claims have as yet proved payable, though a number have been taken up, and some small amount of prospecting done. On the north bank of the Waiho two special claims have been taken up by the Waiho Hydraulic Sluicing Company. They have secured a right to forty heads of water for working the terraces by hydraulic sluicing. The Taipo Sluicing Company hold a claim of 80 acres at Seven-mile Creek, Taipo River. Water rights have been secured, and a contract let to construct a race to bring in sixty heads from the Seven-mile Creek to sluice the terraces near the Taipo River. The Bell Hill Gold-mining and Sluicing Company hold a claim of 50 acres at Bell Hill, and have completed 50 chains of fluming, a dam, and tunnel tail-race. From fifteen to twenty Government heads of water will be worked, with a pressure of 90 ft. Ten men are employed. West Coast Dredging. The Matakitaki Gold-dredging Company are at work near Murchison, and report having won 362 oz. of gold, valued at £1,396 lis. 3d. Ten men are employed. The Cocksparrow Gold-dredging Company have sold their dredge and plant to a party of men who are working with fair success near Three-channel Flat. The Buller Gold-dredging Company are engaged on their claim of 37-J- acres at Fern Flat, Murchison, but the returns of gold are not published. Thirteen men are employed. Concluding Bemarks. The prospects of alluvial mining throughout the Karamea and Westland Mining Districts are of a hopeful nature, and the continued yields of a substantial character from the various fields are likely to be maintained in the future. The necessity for increased water-supply in order to profitably work the gravel drifts in which the leads do not contain gold in quantities that would prove payable under present conditions is, however, apparent alike in respect to terrace workings and deep ground. It is to be hoped, therefore, that the encouragement offered by the Mines Department by way of subsidy on water-races will tend to induce private enterprise to undertake the more urgently required works of this description. On the completion of the water-race now in course of construction by the Consolidated Goldfields of New Zealand the vast deposits of Humphrey's Gully will be enabled to be profitably worked; and, should adequate provision be made for utilising the water stored in Kanieri Lake, the drifts at Back Creek, Seddon's Terrace, and the terraces to the southward of the Hokitika River will furnish profitable employment to a much greater number of miners than are at present at work in that locality. The deep levels at Ross Flat before long will doubtless attract sufficient capital to provide machinery for pumping out the water which now precludes the possibility of working the rich leads known to exist below water-level. The new hydraulic-sluicing operations at Black Ball,
C—3
130
Barrytown, Charleston, and other localities will, when the projected water-races have been constructed, also furnish employment to large numbers of men, and consequent increased production of gold. The opening of new ground at Kumara by the construction of No. 5 tail-race, and the additional storage at the Loop-line Dam, will tend to increase the returns by the maintenance of a more regular water-supply, recent prospecting operations having demonstrated the existence of payable deposits at the lower levels in this district. Otago District. Maerewhenua. This field still maintains a limited population. The extent of land worked on the Livingstone portion of the field is about three miles in length by three-quarters of a mile in width. The wash generally consists of 3 ft. of surface sand overlying 6 ft. of blue shell-stone boulders, under which lies 10 ft. to 15 ft. of gray sand, which overlays "about 4 ft. of green sand, under which is about 2 ft. of quartz-gravel wash lying on the " Maori bottom." The gold is chiefly found in the quartz wash and green sand, but, as the stripping has to be removed, it will be seen that an ample supply of water is required to sluice the whole face. Several parties also work out the wash lying on the " Maori bottom "by driving, and are dependent on the rainfall in order to wash up. There is one elevating plant on the field, owned by Christian and party, who work to a depth of 30 ft. About twenty-six men are employed in sluicing and eight men in driving out the washdirt in the Livingstone district. Maerewhenua Range lies on the opposite side of the Maerewhenua River to Livingstone, and the area over which gold is worked about the same. There are two water-races brought in from the left-hand branch of the Maerewhenua, and several other races from small creeks, together with catchwater clams. All the water at present available throughout this district is insufficient to meet the requirements, and, unless a further supply can be obtained, no increase in the number of claims worked is probable. The number of men employed is about thirty-six, and the average earnings do not amount to ordinary wages per man. The Mountain Hut Water-race is not yet completed. Should it, however, be practicable to bring in the five heads of water to the point to which the survey of the race was made, a considerable area above the level of the other water-races could be worked to advantage. Naseby. Mason and Company's claim at Spec Gully is worked by ground-sluicing, with a pressure of 300 ft. supplied by 13 m., 11 in., 9 in., and 7 in. piping, with a Little Giant nozzle. About two sluiceheads and a half of water are available. There is an elevating plant on the claim, but it is not now in use, owing to scarcity of water. There being an ample fall from the terrace workings, a return of 1 gr. to the yard is payable in most of the ground, only one man on shift being necessary to keep the work going. Three men are employed. A considerable number of men are engaged on the terraces near Spec Gully, and obtain water from the Government race. There are also a number of small parties of men making a living by working the old ground. In Mulholland's Gully and Robinson's Gully the workings are chiefly carried on by the Chinese. Several parties are engaged in operations in Wet Gully, with fair success. In Enterprise Gully Young and party continue to work their claim, the ground being about 40 ft. in depth. They hold a water-race capable of conveying three sluice-heads of water, and are meeting with fair returns. Several other parties of Europeans and a number of Chinese are engaged in sluicing operations in the gully below Young's claim. Hogburn, or Main Gully : Inder Brothers, John Hore, Baxter and party, and Read and party are working their claims on the elevating system. A number of other claims have also been marked out, the ground being taken up in large areas extending for fully four miles and a half along the gully. It is intended to work these claims by elevating, but it will be necessary for the main water-race to be enlarged in order to secure a sufficient supply of water to do this. Guffie, McLaren, and Paisley hold a 100-acre claim about a mile and a half below the Township of Naseby, and are elevating with water from the Government water-race with a pressure of 100 ft. for three sluice-heads and a half. The yield per cubic yard is about 7gr., and the owners are so well satisfied as to the prospects of their claim that they are erecting a second elevating plant; but their operations have been hampered by the lack of a permanent water-supply, the time worked during the year being only equal to four months. They report their return of gold for the year at about 400 oz., valued at £1,560. It is intended to put a dredge on the claim to supplement the two elevators. Three other elevating claims have been at work during the past year, which worked night and day whenever water was available, all it is understood with good results. On four others in same locality plant is now being got ready to be placed in position before winter sets in. The total value of water supplied from the Government water-race during the year was £1,580 Is. lOd. The average number of miners supplied with water was 665, an increase of 5-25 over that of last year, and the approximate quantity of gold obtained by parties using water from the race was 3,157 oz., valued at £12,154 9s. During my visit to this district in November last, in addition to the five parties elevating in the Hoo-burn Gully, ten parties of Europeans and twenty small parties of Chinamen were employed. These were scattered over the gullies from Kyeburn to the Township of Naseby. Altogether about a hundred Europeans and seventy Chinese are working.

Wheeler and party continue to work their claim in the Idaburn, and prospecting has also been carried on in the Wedderburn district, but no valuable discoveries have been reported. At Blackstone Hill, Rose's claim, which has been successfully worked for many years, still continues to yield profitable returns, and other parties of men are also engaged in this locality, and are fairly successful. Welshman's Gully. The Shamrock Elevating Company (Simmonds, Hesson, and Company) occupy 60 acres, on the working of which Mr. Simmonds gives the following account: " Welshman's Gully is situated about five miles from St. Bathan's, on the Blackstone Hill side, commencing about one mile above the footbridge on the Manuherikia River, on the main road to Naseby. The gully appears to have been at one time one of the outlets of the Manuherikia, as the wash is of a similar nature, and the gold is of the same class. The gully runs nearly parallel with the Manuherikia, about two miles in length, varying but little in depth throughout, the mean depth being about 14 ft. The wash is waterworn, and of a coarse nature, with a great number of yellow boulders, varying in size from 9 in. to 18 in. in diameter. The gold appears to be distributed through the wash more or less throughout the gully. The bottom, where we commenced operations, is composed of a hard blue reef, running east and west, which, after exposure, becomes soft and crumbles away. The surrounding deposits are of a granite formation, with the exception of the Manuherikia River and this said gully. We have 30 acres in this place, and we have also 30 acres on the granite formation, in a gully known as Dip or Station Gully. We have done a good deal of prospecting, and in most places obtained a little fine gold from the surface to a depth of 12 ft., the gold running in layers. It is our intention in the near future to place an elevating plant in the gully, but before doing so we have to construct two miles of sludge-channel, and also to erect 14 chains of 15in. iron fluming across a gully to bring water to the ground. We have a water-race from the Manuherikia River about twelve miles in length, with a carrying-capacity of eighteen heads of water. We have just erected a plant, on the Welshman's Gully Claim, consisting of 3,000 ft. of iron pipes, varying from 9 in. to 15 in. diameter, for the main line leading to the elevator. The branch pipes for breakingdown purposes are 7in. Our working-pressure does not exceed 250 ft., which will do the work with satisfactory results, as we do not lift over 25 ft. vertical. We have a tail-race running on the main bottom which conveys the drainage, working water, and silt into the Manuherikia, a distance of 700 yards. Half of this tail-race has been cut through solid rock on an average of 9 ft. in depth. The boxes used are our own invention, and have been in use for over five years in the Last Chance Elevating Company's claim, Bald Hill Flat, and we find they are very little the worse for wear. The run is 60 ft. in length, made of 16-gauge sheet steel 6 ft. by 3 ft. turned up 1 ft. on each end to form the sides of the boxes, making a 4 ft. box 3 ft. long. The head-box, or elevator-box, is made in the form of a case with the running end open, 5 ft. high, made in sections. The elevatorpipe passes through the bottom of the head-box about 6 in. from the back end, and projects 4 in. to. 6 in. above the ripple-bars on the top, inside the head-box, directly over the elevator-pipe, and allowing for curve of water a striking-plate is placed to break the force of pressure and to prevent wear-and-tear. The dirt and stone strike this, preventing injury to the head-box. We use crossbar ripples in frames of five bars, each bar being 2-Jrin. by the angle piece underneath being made of 16-gauge steel riveted to the top bars. These ripples are found very effective. We also use a second set of boxes, 24 ft. in length by 2 ft. 6in. wide, made similar to the top boxes. These are placed in an excavation on a level with the inlet to the elevator, with a fall of 10 in. to the 12 ft. In these boxes we can always depend on getting 90 per cent, of the gold. We have 12 ft. of matting at the tail. The lower boxes are very effective, in that they obviate the necessity of the gold passing through the elevator, and can be readily cleaned up. We can put through the elevator on an average in the twenty-four hours about 170 yards. Three shifts are worked when water is available, and, on an average, ten men are employed." St. Bathan's. Mr. John Ewing still continues to work his claim at Kildare Hill. During my visit in November last the claim was idle, in consequence of a breakdown in the water-race. The depth from which the elevators raise the drift was said to be 135 ft., and I was informed it was intended to continue to a further depth. M. and E. Company (Area, 50 acres).—This claim is owned by the United M. and E. Waterrace Company (Registered). The work carried on has been stripping off the top drift and removing stones to enable the quartz wash and drift to be worked by elevating. Fifteen heads of water are used for sluicing, the pressure being 300 ft. Upwards of 10,000 yards of material were washed, the yield from the gold-bearing leads averaging 3s. 10d., and in the top drifts from 4d. to 6d. per cubic yard. Nine men are employed by the company, and work was carried on in the claim 290 days during the year. Eagle and Gray's claim was idle at the time of my visit, owing to want of water. Several small parties and individual miners earn a livelihood in working the old ground. Surface Hill. —The Scandinavian Water-race Company (Registered) own a claim of 36 acres. The drifts are worked by elevating, and 28,000 cubic yards w 7 ere sluiced away during the year, for a yield of 180 oz. of gold. The claim has been worked during eleven weeks of the year, as the company sell all the water they can, the surplus only being used for their own claim. Upwards of £2,000 has been expended on the race to secure a larger supply of water. Fifteen men are employed, mostly on the head-race. The water-race has now a capacity of ten sluice-heads, with a pressure of 300 ft. The St. Bathan's Water-race Company also own and work a claim of 55 acres at Surface Hill. The method in use is hydraulic sluicing, by which 24,200 cubic yards of drifts and wash were dealt with, for a yield of 3d. per yard. Four shareholders and one wages-man were employed. 18—C. 3.

A few individual miners are also at work in this district, and earn a somewhat precarious living by sluicing. Vinegar Hill and Cambrian's. Never Fail Claim (Area, 10 acres). —The owners of this claim, which has been profitably worked for the past twenty years (Messrs. Hughes, J. and E. Morgan, and Mills), have recently acquired an increased water-supply, a line of 15 in. iron pipes being used for the purpose. The claim was in active operation at the time of my visit, four men being employed. The last washing-up yielded 320 oz. of gold, valued at £1,232, for a period of eleven months. Ewing's Claim. —At the time of my visit this claim was idle, on account of the scarcity of water. Excell and Coulson, Fordham and Gay, and Davis and party were all at work when I visited this district, and it is understood that their returns are satisfactory. The claim situated between Cambrian's Township and Dunstan Creek, owned by Mr. J. Ewing, was also at work, and elevating operations were being carried on, with satisfactory results. Matakanui. Undaunted Gold-mining and Water-race Company, Limited (Area, 45 acres). —Operations are carried on in this company's property by hydraulic sluicing. The water is conveyed from the head-races by three different lines of pipes, with pressures of about 350 ft., 270 ft., and 230 ft. respectively. The number of men employed depends on the supply of water, but is generally from five to ten. This season's water has been very short, only about four months' water being available to carry on work to advantage. The Mountain Race Gold-mining Company amalgamated with this company on the 22nd August, 1896, which gives the new company command of about 40 acres of known payable ground. The depth of the present face is about 65 ft., the upper part (about 33 ft.) being composed of very compact clay intermixed with layers of gravel. The remaining 32 ft. is very heavy wash, which is elevated with an 11 in. elevator, the nozzle used in the bottom being 2f in. in diameter and the throat-piece 5 in. Sims and Morgan's claim, Ewing and McConochie, the Sugar-pot, Matakanui Water-race Company, and Sheehan and Barron's claims are all worked for profitable returns, the ground in the locality being, on the whole, considered rich. About forty men were employed in these claims. In the Devonshire and Drybread seven claims are at work, employing about twelve men. Pactolus Claim, Shotover Biver. —This claim is held under special conditions from the Warden, whereby the owners are entitled to work 70 chains of the river-bed. The wash is raised by a suction elevator. The nozzle from the water-pipes is If in., and, as there is 250 ft. of pressure and a supply of three sluice-heads, there is considerable power available. The pipes are brought along at the level of the beach, and the nozzle injects water into a horizontal pipe at a bend from which the suction-pipe extends downwards to the bottom of the workings. The owners find this a very economical method of working the river-bed, which became too poor to be worked by the ordinary methods. The ground had been abandoned for twenty-four years, and was thrice worked over before that time. A yield of \\ gr. per cubic yard can be made to pay for working, and the owners, Messrs. Rogers and Tripp, are satisfied with their earnings. Enterprise Claim, Skipper's Greek (Area, 14 acres). —This claim is held by Alfred Smith and Sons. The wash is raised by a suction elevator, two sluice-heads of water, with a pressure of 400 ft., being used. A paddock 20 ft. square is worked to a depth of about 20 ft. per week, and yields about 4 oz. of gold. Four men are employed. Alpine Claim (Area, 50 acres). —The owner, Mr. R. Johnson, has given an option of purchase to the New Zealand Minerals Company, and a prospecting drive of 600 ft. has been put in. On account of the dry season, little water has been available for sluicing, and no returns have been forwarded. Blue Jacket Claim, Maori Point (Area, 8 acres). —This claim is owned by Mr. J. S. Collins. There are altogether in the claim some 500 ft. of piping, 16-gauge steel, commencing with an intake gradually tapering from 18 in. to 9in., with a Little Giant director. The water for use is stored in two large dams during the night, so as to give sufficient to run fifteen heads for some four hours during the day. The ground is about 140 ft. in depth, and is very stony, there being three layers of wash, of an average depth of 4 ft. each, all carrying fine gold. The wash stones are got rid of by being broken and forced into the tail-race by the jet of water from the nozzle. This tailrace is 16 ft. deep, cut in rock, boarded to a height of 3 ft. and 2 ft. 6 in. in the bottom. For saving the gold light tramway-rails are laid longitudinally for 100 ft. in length, with about 2 in. of scrub between the rails and bottom of the boxes. This forms a catch for the gold as it gets worked down between the rails, which are about 1 in. apart. It is found that the rails make a very even bottom, thereby helping away the stones. The gold in the layers is very fine, but the bottom gold, or that found on the main bottom, is of a much coarser nature than that in the high layers. The top or high layers, together with the gold in the main bottom, would give a return of about 100 oz. with four hours' water per day for twelve months, with two men's labour. Aspinall's Claim (Area, 5 acres). —This claim was famed for its richness in the early days, gold to the value of over £60,000 having been taken out by different parties. The ground has now been worked by ground-sluicing for nearly twenty years, first by hose, and now by a very complete sluicing plant. There has been a very considerable amount of tail-race cutting in the solid, the ground being very deep at the back. An underground tail-race, 370 ft. long, in the solid rock has just been completed. The water is brought in by a race a mile long to two good dams, and from thence is conducted by 11 in. piping under a head of 250 ft. pressure to the workings below. The ground remaining to be worked is a little less than 3 acres. Work has been rather slack this season, on account of the scarcity of water.

Queenstown and Lake Wakatipu. Maori Gully Sluicing Claim (Area, 13 acres). —This claim is situated at the Twelve-mile, Lake Wakatipu. The owners, Messrs. Woodhouse and Houston, are ground-sluicing, with fifteen heads of water, for fairly profitable results. Moonlight Sluicing Company's Claim (Area, 54 acres 2 roods 21 perches).—Three men have been employed in this claim during the year, and 173 oz. 12 dwt. of gold, valued at £668, has been obtained. The Sugar-loaf Sluicing Claim (Area, 17 acres; Lawrence and Lynch, Owners). —During the year no sluicing operations have been carried on. A race to carry eight sluice-heads of water is being constructed for a distance of four miles and a half, the work being chiefly done by contract. Alexandra South. The Golden Beach Hydraulic Company are working a claim of 120 acres. The elevating plant, which is capable of raising the river-wash from a depth of 40 ft., is worked by twelve sluiceheads of water, with a pressure of 1101b. to the square inch. About a quarter of an acre of gravel has been worked, for a yield of 461 oz. 15 dwt. of gold ; value, £1,777 15s. 3d. Seven men were employed. Bald Hill Flat. The Bald Hill Flat, commonly called " Spear-grass Flat," is a flat or valley situated at the foot of the slopes of the Old Man Range, directly below the Old Man Rock, it being at one time one of a chain of lakes which I have no doubt existed in Central Otago centuries ago, drained by a number of small gullies and by the cutting-down of the Molyneux or Clutha River. In my opinion this particular flat or basin was drained by two outlets, one at the north end, known as Butcher's Creek, and the other at the south end, known as Coal Creek. This basin consists of about 1,000 acres, and has been prospected throughout. It has been proved that three-fifths of the flat contains gold in payable quantities for the hydraulic-elevating process of mining, and probably for dredging purposes would pay handsomely, as six times the quantity can be put away by the latter process. Very little mining has been done in the locality until within the last six years, when the Last Chance Elevating Company started their elevating plant. Since that time others have followed their example. This basin shows by its alluvial deposits that it must have been fed or the deposit brought down from the slopes of the Old Man Range by the action of water, as the wash is composed principally of broken schist-rock and quartz-drift. At the base of the hill in this basin Maori chisels and wooden bowls and the remains of Maori ovens have been found at a depth of 16 ft., the wooden bowls being very little decomposed. The bottom which the miners are working on is composed of various formations, some parts being of soft sandstone, varying in colour; other parts are of a rubbly clay. No defired reef-bottom has been found as yet. Nothing has been done to test what the deposits may be below this false bottom. Carroll and Lynch's Claim (Area, 16 acres). —This claim is worked by elevating. Six sluiceheads are used, the pressure of the water being 200 ft. About 140 yards are washed daily, the yield being about 5 gr. per yard. Six men were employed. Wilkinson s Claim (Area, 6 acres). —A branch tail-race 60 yards in length was cut through a heap of fork stones 25 ft. deep. Four sluice-heads, with a pressure of 100 ft., are used. About 26,400 yards have been sluiced since the tail-race was finished. Four men were employed. The Last Chance Elevating Company are the owners of a special claim of 64 acres. The claim has been continuously worked. Thirteen wages-men were employed. The following description of the locality, workings, and plant has been furnished by the owners :— " The Last Chance Hydraulic Elevating Company started operations about six years ago, their right of water being at that time eight heads from the Gorge Creek. Finding this right failed in certain seasons of the year, they purchased the Commissioners' water right of twenty heads from Shingly Creek, for which they cut a race seventeen miles in length, to convey a portion of this water to Bald Hill Flat. Since then they have purchased Quayles Brothers' rights of twelve heads from Shingle and Chasm Creeks. The whole of these rights give a very good supply the most of the year round. The company holds nearly fifty miles of water-race, which costs about £300 per year to maintain. They hold at the present time a special claim of 64 acres. Since they commenced operations they have washed away about 14 acres of ground, at an average depth of 23 ft. This ground averaged about 8 gr. to the cubic yard. The quantity put away per hour would average 7 cubic yards, or 168 yards per day for three shifts, which we mostly work. The plant consists of 4,000 ft. of pipes, varying from 7 in. to 15 in.; two elevating plants, with all the necessary valves, ball-joints, Little Giants, and bends for the working of the two elevators, which we have not worked for the last two seasons, owing to the scarcity of water. Our pressure is 320 ft., and we lift 31 ft. with good results, with 4f- heads of water in the pressure-pipes. The washing appliance for each elevator consists of 60 ft. of iron boxes 4 ft. wide, being bolted together for the convenience of erecting. These boxes are the company's own design, and found to be far superior to wood in every possible way. The ripples used on both lines are cross-bar ripples, made with 2f in. by fin. flat bars for the running part, and 16-gauge steel plate made in the form of angle iron, 2 in. in depth, riveted under bar to form the ripple. The company finds that this ripple cannot be excelled for gold-saving purposes. The company also use 24 ft. of boxes in the paddock, which the whole of the dirt passes through before passing into the elevator. These boxes are also iron, and provided with the same description of ripple as the elevator-boxes. In the lower 24 ft. of boxes the company can always depend on saving nine-tenths of the gold obtained from the paddock."

Boxburgh. Louden and party, consisting of four men, occupy a, claim of 30 acres situated at Roxburgh East. The drift, which is about 60 ft. in depth, is washed away by sluicing, but in order to more effectually deal with the bottom wash a small hydraulic-elevating plant has been erected. The Roxburgh Amalgamated Mining and Sluicing Company (Limited) still continue to profitably work their claim. The secretary of the company has supplied the following information respecting the claim : — " This company owns a property of about 100 acres, situated on the banks of the Molyneux, opposite the Township of Roxburgh. The claim is being worked under the management of Mr. William Peters on the hydraulic-elevator system, running four elevators continuously (two being second lifts), using in all forty-five heads of water. During the past dry season work at the claim was stopped for about six weeks, owing to the scarcity of water. The company suffers from the disadvantage of having to submit to prior rights drawing water from the Teviot Creek, notwithstanding the fact that the supply is obtained from the dam at Lake Onslow, built at the expense of the company. The company employ about thirty men, the average wages being about Bs. per day per man, exclusive, of course, of the manager's and assistant manager's salary." i Golden Bun Hydraulic Sluicing Company (Area, 100 acres). —This claim is situated at Miller's Flat. The workings are on a large alluvial flat, and the hydraulic elevators are worked with fifteen sluice-heads of water, having a pressure of 300 lb. per square inch. Sixteen men were employed. Island Block. Island Block Gold-mining Company. —Operations have been carried on in elevating from the workings on the flat, and also in prospecting on private property on the eastern side of the Molyneux River. No return of gold obtained has been made. Eadie and Kirkpatrick's claim, of 30 acres, is still being worked by hydraulic sluicing. Ten men are employed. No return of gold recovered is obtainable. Tuapeka. Blue Spur and Gabriel's Gully Consolidated Gold-mining Company (Limited). —This company's claim still continues to be most successfully worked by Mr. J. Howard Jackson, to whom I am indebted for the following extract from a report to the directors, dated the 15th March, 1897, as well as the drawings (which are reproduced with this report) illustrating the latest improvements in the hydraulic-sluicing plant:— " Total net value of gold won during the year 1896-97 — i.e., from the Ist March, 1896, to the 28th February, 1897—3,523-69 oz.; value, £13,919 2s. Water used in hours' sluicing-time : No. 1 division of mine, 3,985-5 hours ; No. 2 division of mine, 3,931 hours : total, 7,916-5 hours. " The two main items of expenditure are wages and explosives, and the cost under these heads is as follows :—Wages: No. 1 division of mine, £1,575 4s. 7d. ; No. 2, £2,375 19s. 2d.: total, £3,951 3s. 9d.

" Roburite was used almost exclusively, and proved satisfactory both in regard to the work done and comparative cost. The largest blast fired contained 1,6501b. of roburite, which I estimate to be equal in effective force to not less than 3 tons of best blasting powder. Roburite has been used at the mine for some years now, in many instances by men having no special knowledge of the use of explosives, and no accident of any kind has occurred in connection with it.

December, January, and February show a falling-off of 124-5 hours' sluicing-time as compared with the corresponding period of the previous year. During February less than in. of rain fell in this neighbourhood. " The average number of men employed during the year has been forty-one, at wages ranging from 12s. 6d. to 7s. per diem. Of this number, six were constantly employed on the head-races." The Local Industry Claim and Mill's claim are both being worked in this locality, with satisfactory results. Weathers tone's. Golden Bise Claim (Area, 33 acres). —Messrs. Smyth, Doulan, and Adams are working the claim, with satisfactory results. The pipes have been extended and altered,, at a cost of £300. A hydraulic-elevating plant is used, the height to which the wash is raised being 15 ft. About five sluice-heads of water are used, at a pressure of 190 ft. Five men are employed. Waipori. Waipori Deep Lead Claim (Area, 130 acres). —This claim is owned by the Amalgamated Waipori Deep Lead Gold-mining Company (Limited), and is worked by hydraulic elevating.

through was 90,000 yards, for a yield of 1-63 gr. per cubic yard. Ten men were employed at the claim and fourteen at race-cutting. Long Gully Claim (Area, 6 acres). —This claim is worked by the owners, five in number. They use a hydraulic elevator, with four sluice-heads of water, having a pressure of 130 ft. There are 60 ft. of boxes, 3 ft. wide, fitted with Venetian ripples. The wash-dirt is elevated from 15 ft. to 19 ft. Bakery Flat Claim (Area, 84 acres). —This claim is owned by the Bakery Flat Sluicing Company. The manager, Mr. J. T. Johnson, informs me that the company has only been in existence a few months, and work is not sufficiently developed to warrant a report. Waikaia. The Argyle Hydraulic Company, of Waikaia, is in possession of a special claim of 74 acres in Winding Creek Flat, and an extended claim of 6 acres at Frenchman's Hill; also a water-race 11 miles in length, and a right to twenty-four sluice-heads of water, twelve of which are used in carrying on ground-sluicing operations at the extended claim. The pipe line is over 600 ft. in length, giving at the working-face a fall of about 80 ft. The wash is of a very light character, and is treated at the rate of about 60 tons per hour. The other twelve heads of water are used for hydraulic elevating on the special claim, the main pipe line in this ease being a mile in length, giving a vertical fall of 315 ft. from the race to the claim. The ground is 40 ft. in depth, consisting of a heavy schist boulder wash lying on a bottom of soft sandstone. The material requires to be elevated to a height of 55 ft. in order to give room for stacking tailings. The power obtained from twelve heads having a fall of 315 ft. is sufficient to elevate the stuff to a height of 60 ft., or 65 ft. if necessary. Though only a prospecting paddock has been opened the ground is proved to be payable, and rich prospects were obtained from the bottom layer of wash. Twelve men were employed. Kennedy's Claim (Area, 4 acres). —The wash is from 60 ft. to 100 ft. in thickness, but only 6 ft. to 7 ft. of the bottom layer is taken out. This is done by driving, and the wash-dirt taken out and sluiced, the yield being from 2f-dwt. to 3 dwt. per yard. Four men were employed. The Break-em-All Claim is again taken up, after the ground had been comparatively idle for fifteen years. An Otago syndicate are about to provide funds for the erection of an elevator and construction of water-races. ■ ■ The Panama Water-supply and Gold-mining Company (Limited) has taken up a claim on the banks of the Mataura River, and is constructing a race to bring in water from Fiery Creek. It will yet be some time before sluicing operations are commenced. Nokomai. The Sew Hoy Nokomai Hydraulic Gold-mining Company's claim, of 128 acres, is owned by Sew Hoy, a Dunedin merchant. Of the water-race, six miles and a quarter was constructed, the total length being now twenty miles, having two siphon crossings of 3,400 ft. and 720 ft. respectively, the pipes being 18-J-in. in diameter, made of Bto 16 gauge of steel. The race is capable of carrying fifteen to twenty sluice-heads of water, with 550 ft. pressure. Two sets of elevators working in connection with 2,050 ft. main line steel pipes and 1,335 ft. service pipes are used for elevating and sluicing the drift, and a 3-horse-power motor for driving the dynamo for the electric light. No account was kept of the quantity treated, nor has any return of gold obtained been furnished. Fifteen men are employed. Golden Terrace Hydraulic-sluicing Company's Claim (Area, 100 acres; situated about a mile below the junction of the Nokomai and Mataura Rivers). —The Golden Terrace Company, a private company of fifteen shareholders, was formed on the sth August, 1896, with a capital of £3,000, to take over and develop a claim and water right held by a party of five working miners who did not possess the necessary capital requisite for such development. Immediately on becoming possessed of the property the company set to work in a systematic manner to develop it by constructing a water-race 5 ft. in width and 2 ft. in depth, capable of carrying twenty-five Government heads of water, the total length of which is two miles; also by placing on the ground a thoroughly efficient hydraulic-sluicing plant. The main pipe line is 12 B.W.G- steel, 18 in. diameter, double riveted; and its total length is 1,400 ft., and it gives from the race to the working-face a total fall of 300 ft. vertical, or a water-pressure equal to 128 lb. per square inch. The total depth of the gold-bearing drift is about 280 ft., largely mixed with schist and quartz boulders, some of the latter being very large. Some of the layers of wash through the face carry gold in quantities equal to 2 dwt. of gold per cubic yard. The average quantity of gold per cubic yard from the face, 280 ft. in height, from prospects obtained, appears to be from 4 gr. to 6 gr. The material is treated by ground-sluicing in the ordinary manner, the face being brought down by streams of water from two nozzles, one 3 in. diameter the other 2-J-in., and is then run through boxes 3 ft. in width, which are lined in the bottom with angle-iron bottoms, with cocoanut-matting underneath; and thence over a system of concentrating-boxes, they being lined with steel plates J in. in thickness, having perforations of J in. in diameter at ljin. centres, cocoanut-matting also being used underneath these to save the fine gold. The quantity of water used, on an average, will be about twelve heads, or sufficient to treat 40 cubic yards of material per hour for twenty-four hours per day. The amount of capital expended in development has been about £2,900. Eight men are employed. No returns are yet to hand, the plant not having been completed, and sluicing operations only lately commenced. Southland District. Bound Hill. The Round Hill Company are still energetically carrying on operations, and have recently completed extensive enlargements in connection with their water-supply. Port's Race has now a capacity of twenty-seven Government heads of water, whilst the continuation of the Cascade Race

136
will now carry fifteen heads. In all, the company's races have at present a carrying-capacity of thirty-six Government heads of water, and further extensions are contemplated in the near future. The reservoir in the Onrawera Gorge will, when completed, have a storage-capacity of 24,000,000 gallons of water. During the year the company manufactured on the spot some 90 chains of 27 in. pipes and 30 chains of 18 in. pipes, the annealed steel plates being imported from England. The whole plant is of a most complete and modern character, and the company is now enabled to work much more efficiently than in former years. During the year 1,238 oz. of gold, valued at about £5,000, was won. Fifty men were employed. The Ourawera Company have a claim of 20 acres adjacent to the Round Hill Company, and, the difficulties in respect to water-supply, &c, having been overcome, it is hoped that good returns will be made for the next year's working. At Wilson's River and Preservation Inlet alluvial mining is practically at a standstill, only a few parties of men being engaged, and these are meeting with but indifferent success. At Orepuki increased activity has been manifested, and the prospects of the district appear to be on the up grade. A lead parallel to the coast, near the Waiau River, has been all pegged off, the indications being of a hopeful character. General Bemarks. During the year the exceptionally dry weather in a very great measure lessened the watersupply, and many of the water-races supplying water for hydraulic elevating and sluicing purposes were almost dried up. The yield of gold from alluvial claims was, in consequence, much less than was expected. It is, however, to be anticipated that, with the additional area of land taken, up and the number of water-races recently completed, a decided increase on last year's yield of gold will be obtained. The activity displayed throughout the Naseby, St. Bathan's, Shotover, Lake District, Clutha, Tuapeka, Waikaia, and Round Hill districts gives evidence that those fields are not exhausted, but that with improved appliances and a better water-supply the yield of alluvial gold will continue to be of importance for many years to come. Dredging. The success attending on operations in the direction of the recovery of gold from the beds of rivers by means of dredges is every year adding to the demand for suitable dredges and machinery. Improvements in the construction and adaptation of these machines are leading to their application to work wet ground that up to the present could not be dealt with through want of the power required, and in the absence of necessary water-supply. Should the anticipations of success for this method be borne out after trial in the wet ground, where neither sufficient fall nor water-supply for sluicing is available, large areas of auriferous alluvial ground will be made to yield a profit that have up to this time scarcely been touched. The skill of the different mining engineers is being shown in the improvements made. Each new dredge now being built is furnished with the latest and most suitable machinery both for elevating the gravel, washing out the gold, and conveying the washed gravel, elevating, and stacking it at a distance from the dredges; thus leaving the vessel free to float, and to be moved to the most suitable place for carrying on the work. The following is a list of the claims taken up for dredging : —

Upper Shotover. The New Sandhills Gold-dredging Company have 70 acres on the Upper Shotover, and employ nine men. Power for the dredging plant, pumping, and lighting is supplied by two electric generators, driven by water-power, two motors being placed on the dredge. Sandhills Dredge. —The following description of the Sandhills Dredging Company's plant and operations is taken from the Lake Wakatipu Mail: — " The Sandhills dredge was built six years ago, the total cost of it being £7,000, of which some £800 was paid for freight and cartage. The dredge was built on the company's first claim, which extended from the Sandhills to Rapid Creek. Although it was well known that a greater portion of the claim had been formerly worked, the company was led to expect substantial returns from the rich patches left untouched. The actual returns, however, proved disappointing, and after five years' work with indifferent results the property changed hands, and the work is now carried on by a small Dunedin company. " With regard to the electric power by which the dredging is carried on, it will be of interest to give some account. The generator-station is situated about seven miles from Skipper's Point, and three miles from where the dredge is at present working. This part of the plant consists of two Brush Victoria generators driven by an ordinary 4 ft. Pelton wheel. The machines are capable of giving a total output of 52 kilowaths or 70-horse power. The water for driving purposes is brought in by a race from a creek about two miles distant. A pressure-tank is placed 525 ft. (vertical) above the generator-station, from which a line of pipes delivers the water at a pressure of 232 lb. to the square inch. "The plant is equipped with a very complete set of measuring and controlling apparatus, and the station is connected with the dredge by telephone. A Buss Sombast tachometer —an ingenious piece of mechanism—is mounted on one of the generators and driven direct from the armature shaft. This instrument continuously records the speed of the machines without the usual reference to a timepiece and consequent arithmetical calculation. A Soames Nalder ammeter registers the amount of current, and a Carden volt-meter, designed to read up to 4,000 volts, indicates the electrometer force. Two electro-magnetic cut-outs are included in the main circuit, to prevent damage to generators and motors in the event of a short circuit or total disconnection. In the event of either of these happening the ' cut-outs ' automatically switch the power into a set of resistance coils capable of carrying the maximum working current. This arrangement works admirably, and I was told that it had frequently prevented serious damage to the more delicate parts of the machinery. " A Brush lightning-arrester is connected with each conductor immediately inside the building, which effectually prevents damage from that source. The generator-station and all machinery therein are kept scrupulously clean, and appear to be carefully attended to. " The conductors which convey the power to the dredge are carried on patent fluid insulators supported (2 ft. apart) on iron rails, the telephone-wire occupying a central position immediately above. I am told that, notwithstanding the heavy current present in the power conductors, no inconvenience is caused by induced currents in the telephone-line. This trouble was anticipated, and the fear of a similar drawback led to much opposition to the proposal to drive the Dunedin city trams by electricity. The telephone instrument in use is of the ordinary kind, and, although working under great disadvantages, the transmission is excellent. To prevent damage to the telephone from accidental contact with the power line an exceedingly fine safety-fuse is included in the telephone circuit. " Leaving the generator-station, a three miles' walk for the most part on the river-beach takes us to where the dredge is now working, under Muddy Creek Terrace—and, by the way, I may mention that the track is nothing to brag about. This three miles of bad road, or no road at all, is a great drawback to the working of the dredge. From the Skipper's dray-road there is already a trolly track made (but not kept) to the generator-house ; from there the heavy machinery for the dredge has to be conveyed the remaining three miles as best one can. " Midway between the generator-house and the dredge you come to two fails in the river—one 10 ft. and the other 12 ft. About ten mouths ago it fell to the manager's lot to get his dredge over there, and any one seeing the place can estimate the difficulty. The fact of the dredge getting over, after being lightened of all her gear, without any injury whatever, in spite of the unavoidable rough handling, speaks volumes for the care both of the manager, Mr. White, and Mr. R. Hay, Dunedin, the designer of the dredge. " Reaching the dredge you get aboard by means of a boat attached to one of the quarter lines. Fortunately, at the time of my visit the river was in excellent condition for dredging, and the dredge was working well in solid ground (i.e., ground never previously worked), and is in every way splendidly adapted for dredging. The power is conveyed from the land-lines by means of flexible cables suspended at a convenient height above water. After passing through guide-blocks they are led to revolving drums (part of the recent alterations, and a great improvement on the old method) by means of a revolving connector attached to each drum. There is no interruption in the connections while paying out or taking in the cable. "The two motors are duplicates of the generators, the electrical plant having been constructed specially for the work. The several parts of all the machines are interchangeable, and a spare armature and field magnet are provided in case of an accident. Al6 in. centrifugal pump is worked by one motor, and the other drives the buckets, winches, and other gear in connection with dredging. All the necessary switches, shunt coils, &c, for controlling the machinery, &c, are placed in convenient positions on deck. The small space occupied by the whole plant, and the ease with which it is handled, makes electricity a very convenient power for any class of work, and the.necessary gear will compare favourably in point of weight, dimensions, and multiplicity of parts with any
139

ordinary steam plant. The pump, main shaft, and counter-shafts are driven by 5 in. rope bands, and have proved to be durable, efficient, and especially adapted to the work of the dredge. " The dredge is 90 ft. long and 20 ft. wide, and is constructed entirely of steel; all the buckets, pins, links, and other parts exposed to wear and rough usage are of the same material. The bucketladder is designed so as to bottom, if found necessary, 22 ft., and to discharge a ton per minute. It is, however, seldom that the dredge works near the maximum limit of either the depth or discharge. Originally the whole of the upper deck was devoted to gold-saving appliances, consisting of a revolving screen which delivered, the rougher material into a chatte laid with longitudinal ripples. The finer material was delivered out of the screen and run over two cocoa-matting tables, one on each side of the screen, the tailings being conveyed aft by means of a side chute. "By the present arrangement the wash-dirt is discharged from the buckets into a short chute overlaid with heavy steel plates ; from thence it drops into the head of the main chute or dummy. The water for washing purposes is pumped into a tank behind the first chute, and carries the material through the chutes. Tailings are discharged 30 ft. astern. The head of the main chute is 16 ft. long by 3 ft. 6 in. wide, the remainder being 40 ft. long and 2 ft. wide. The ripples are quite a novelty in that line, and are made from steel tram-rails; they are of various shapes, and arranged in different positions in the chutes. The portions used in the dummy are bent at angles found most suitable. Owing to the rough nature of the gold the space between each ripple ranges from 1 in. to 2 in. The peculiar manner in which the ripples are arranged causes the wash-dirt to be spread evenly over the whole width of the chute, thus insuring thorough washing before it is discharged. The ripples are laid on strips of wood lin. thick, and set in opposite directions to them, and under these is laid cocoanut-matting. The set and section of the bars make the ripples an excellent catch for coarse or fine gold. An important feature in the working of the ripples is they do not fill and become hard. The ripples are easily made, handled, laid, and lifted, there being no bars or bolts connected with them. A section is kept in its place by means of angle irons laid along the sides of the chutes. The ripples should stand an enormous amount of wear, and can be laid in various ways to suit different conditions of work. Mr. White has had some months' experience in the working of the new gold-saving gear, and he claims for it many advantages over the old style. He informs me that all the evidence of its working goes to prove that practically all the gold is saved. The whole of the gold is got from the dummy, which is washed once a week; the remainder of the chute is washed down once a month, and the result barely pays for the time it costs. In the old style of gold-saving the tables had to be washed every shift, which meant a stoppage of nearly an hour, and an extra band required two days a week to stream down the accumulated washings of the tables. This meant at least fourteen hours a week stoppage. Under the new arrangement all the stoppage required for washing up is three hours per week. " The screen and parts were exposed to much wear-and-tear, and took a considerable amount of power to drive them. Since the alterations have been carried out Mr. White informs me that he has reduced the necessary power by 9-horse power. This alone —during the past year at least—is an immense gain, as, owing to the extremely dry season, the dredge would not have been able to work under the old conditions during the last month for want of water. " The dredge is lighted by two Brush arc lamps of 2,500-candle power each. The lamps obtain the necessary current from the power circuit, and the splendid light given is a great convenience to the work at night. The lamps have been in use over five years, and have given every satisfaction." Shotover Biver, Queenstown. The Sew Hoy Big Beach Gold-mining Company (Limited) hold 167 acres 3 roods 7 perches on the Shotover River, near Queenstown, and work with two dredges portions of the year, twentynine wages-men being employed. The gold won for the past year was 2,040 oz. 8 dwt. 22 gr.; value, £7,904 Bs. 2d. The company own three dredges, 32-horse power each. Victoria Bridge, Kawarau Biver. The Golden Beach Dredging Company have a lease of 31 acres at the Victoria Bridge, on the Kawarau River, and a company which has been formed in London intend placing a first-class steam dredge upon it, as it is considered that the gold obtained in the " sixties " on the beaches of the river and the terraces abutting, as well as the success which has attended the dredge at present working, proves the Kawarau to be richly laden with the precious metal; but, unfortunately, it is for the most part confined to rocky gorges, and is generally on that account too rough for working with present appliances. The river at the Victoria Bridge is, however, comparatively smooth and free from rocks, so that there are fairly good prospects of working it to advantage. Kaivarau-Cromwell. The Electric Gold-dredging Company hold three claims, comprising about 150 acres, at the Kawarau River, near Cromwell, and have two dredges at work —one capable of dredging to a depth of 40ft., and lifting 70 cubic yards per hour; and the other dredging 53ft. deep, and putting through 90 cubic yards per hour. The cost of running the dredges is £100 per week, and the amount spent in building them was £9,000. There are thirteen men employed on the dredges ; the engines are 12-horse power and the boilers 14-horse power nominal. During the past two years the Electric Gold-dredging Company have opened up the Kawarau, which is one of the most difficult rivers in Otago to work. Their operations have so far proved successful, and as they are continually improving their plant, so as to overcome difficulties, they hope to be more successful in future. The whole of the gold in their claims is contained in 6 in. of the bottom, and to get at that 40 ft. of tailings, which will not run 3 oz. per week, have to be lifted. During the season, when the river is in flood, operations are suspended altogether, as the dredges are unable to cope with the drift. 19—C. 3.

Clyde. The Clyde Dredging Company has a very complete plant, the dredge being 93 ft. long by 27 ft. wide over all, and bucket-ladder 60 ft. long. The tail elevating-buckets are of an improved shape, and are intended to carry away all sand and gravel washed. A second small set of elevators will lift the grit and fine sand passing over the tables, and empty it into the main elevators at the level of the deck, to be discharged with the coarser gravel some distance away from the tail end of the dredge. The object of the tail elevator is to give the dredge plenty of room in the deep ground, or where a large quantity of loose gravel has been deposited in the river by terrace sluicers. In order to strengthen and prevent the dredge hugging, she is fitted with two sets of hog-posts, 28 ft. high, four in each set, diagonally braced, and having long iron tie-rods at top from the ladder hoistingframe at the bow to the outer end of the tailing elevator. This deck erection to such a height is considered quite a new feature in dredge construction, and it is thought it will be more generally adopted where deep ground has to be worked. Alexandra. The Chicago Dredging Company hold 57 acres 2 roods on the Clutha River, near Alexandra, and employ seven men, the dredge being worked by steam-power. The Eureka dredge, 80 ft. long, with pontoons 9 ft. wide and 5 ft. deep, ladder 53Jft. long, and ladder-way 4-J-ft. wide, works the river-bed half a mile above the Alexandra Bridge. The plant is capable of dredging 36 ft. deep from the water-surface, the capacity of the buckets being 3 cubic feet. The tailings-elevator, 36 ft. long, is capable of stacking the tailings 20 ft. above the water-level. The Ngapara Gold-dredging Company, at Alexandra South, put through during the year 225,600 yards, for a yield of 940 oz. ; value, £3,619. The dredge is worked by a 12-horse-power steam-engine. Seven men were employed. The Enterprise Gold-dredging Company (No Liability) hold a claim of 55 acres along the river at Alexandra South, and employ seven men on their dredge. The Manuherikia Gold-dredging Company (Messrs. Steel, McGeorge, and party) hold 28 acres at Alexandra South, and employ four men on their current-wheel dredge. The gold won for the year was 289 oz., valued at £3 17s. per ounce. The Manorburn dredge, at Alexandra, has a 12-horse-power nominal engine, pontoons 75 ft. long and 11 ft. wide, ladder (4 tons) 53 ft. long, and ladder-way 4-J- ft. wide. There are thirty-two buckets, each weighing 3 cwt. 201b., and capable of lifting 3 cubic feet each. The capacity of the dredge is estimated at 90 tons per hour. The washing cylinder is 16 ft. long, the perforations being fin. in diameter, and the material treated is distributed over 220 square feet of gold-saving tables, from which the sand is discharged directly into the tailings-bucket, which casts the tailings some distance behind the dredge, where, if necessary, they can be stacked to a height of 24 ft. above the water-level. The fall in the gold-saving tables, which are all fitted with cocoanutmatting, is 1 in 10. Ophir. The Ophir and Ind Gold-dredging Company (Limited) hold a claim of 99 acres at Ophir, and employ six men. They have a steam-engine, with a nominal 10-horse power. Boxburgh, Clutha. The Ettrick Gold Steam-dredging Company (Limited) hold 50 acres about nine miles below Roxburgh. A 12-horse-power compound horizontal surface-condensing engine drives all the appliances connected with the dredge. The Roxburgh Gold Steam-dredging Company's claim of 50 acres is situated one mile below the Town of Roxburgh. The beaches formed in the Clutha River are worked by steam-dredging, the dredge, band of buckets which lifts the w r ash-dirt, and the centrifugal pump which supplies the water for sluicing being driven by a 20-horse-power compound horizontal surface-condensing engine. Six wages-men are employed. The Golden Treasure Dredging Company's claim consists of 50 acres, about twelve miles below Roxburgh, a 30-horse-power compound horizontal surface-condensing engine driving the dredge, buckets, and centrifugal pump which supplies the water for sluicing the wash-dirt. Miller's Flat, Clutha. The Otago Gold-dredging Company (Limited) hold 52 acres at Miller's Flat, and employ seven men. Two steam-engines of 10- and 14-horse power supply the motive-power for dredge, ladder, and elevator. During the year the dredge worked 197 days, and. obtained 660 oz. 18 dwt. 17 gr. of gold; value, £2,544 3s. The Golden Run Dredging Company hold a claim of 50 acres at Miller's Flat, and employ six wages-men. A 12-horse-power compound horizontal surface-condensing engine drives all the appliances. Messrs. J. Pringle, R. Patrick, J. Mclntyre, J. C. Arbuckle, and J. Pringle, who own the Pride of the Clutha dredge at Miller's Flat, have an area of 57 acres, part river (34 acres) and part land (23 acres). The dredging machinery consists of a 60 ft. ladder, forty buckets, six hand-winches, and one steam-winch. Six men from shareholders and two wages-men are employed. Island Block, Clutha Biver, Tuapeka County. The Golden Gate Dredging Company (Limited) have a claim of 50 acres on the Island Block, Tuapeka County, and employ seven wages-men. Dredging operations were started a few chains below the Island Block line of pipes, where some good ground was met with, but it did not prove as extensive as anticipated. Some prospecting has been done lower down the river, and there is

a probability of finding payable ground on the east side of where the prospecting is going on. The dredge, which is in good order, and capable of doing a large amount of work, is driven by a 30-horse-power compound horizontal surface-condensing engine. Lowburn, Clutha Biver. The Wanaka dredge, at Lowburn, is owned by Messrs. N. P. Kloogh, W. Talboys, and HBruce, who hold a claim one mile in length along the Clutha River. Dredging is done by means of a current-wheel, worked by the force of the stream, calculated at about 8-horse power, and lifting 25 tons per hour. Bowman's Flat, Clutha Biver. The Bowman's Flat Company hold a prospecting area of one mile near Bowman's Flat, on the Clutha River, and have spent £3,900 on a dredge, which, with the pontoons, 82 ft. long, have been all made in Dunedin. Earnscleugh Flat. The Earnscleugh Flat Dredging Company (Messrs. C. Weaver, P. Weaver, J. Kelman, A. Black, and J. McPherson) have an area of 33 acres at Earnscleugh Flat, on which six men are employed. Rough gravel is worked in the face with a bucket-dredge, driven by a 12-horse-power steam-engine, and lifting about 8,000 yards per week, giving an average of 2 gr., of the value of 2Jd. Waipori. Messrs. McNeil and party, who own the Perseverance dredge, at Waipori, which is worked by a 10-horse-power steam-engine, have a claim of 84 acres, and employ six men. The Jutland Flat Gold-mining Company (Limited) hold 187 acres at Jutland Flat, Waipori. The ground is worked by regular faces and paddocks, and enclosed within dams to maintain the requisite level for floating purposes. Cement occurs in irregular patches, bands, and beds, and at different levels, and varies in its different positions as ferruginous and argillaceous, occasionally passing into soft arenaceous conglomerates, the latter being chiefly found near the main bottom at the side of the valley. The drift consists of quartz-gravel, more or less rounded, vari-coloured sands and clays overlying schist and lacustrine deposits of pebble-beds, soft sandstones, quartz-grits, clays, and slates, with bands of partly-carbonised driftwood, &c. The estimated yield is 1-49 gr. of gold per cubic yard, value 3d., and the cost of dredging l-38d. per cubic yard. There is a modern and improved plant, driven by 18-horse-power compound vertical surface-condensing engine. In addition to the districts mentioned, dredging operations are being instituted in the Nevis, Waikaia, Waikaka, Gore, Naseby, Waitahuna, Wetherstone's, Glenore, and other districts. The work of building dredges has given an impetus to the engineering trade in Dunedin, and the various foundries are kept employed in furnishing the extensive machinery required for their equipment. The cost of one of these dredges varies from £4,000 to £6,000, and the weekly cost of working is estimated at £30. Six men are found sufficient to man a dredge in ordinary work, but under certain circumstances one or two additional hands have to be employed. The future yield of gold from the Otago District will be largely augmented by the yield from dredging operations, and, although the whole of the land taken up may not be payable, a number of the claims will prove sufficiently rich to afford a handsome profit for working. This method of working river-beds is being adopted in other countries. The success attendant on this branch of the industry is causing inquiries to be made as to the latest improvements adopted on the New Zealand dredges.

WATEB-CONSEBVATION. During my visits to the Otago and West Coast districts the subject of water-conservation was brought forcibly under my notice, and the importance of the question can hardly be overestimated. An abundant supply of water is essentially the life of the mining industry in these districts, and, as will be seen by reference to detailed reports elsewhere, the lack of a permanent water-supply has been the cause of the yields of many of the mines not coming up to that high standard which would otherwise have been the ease. The supply, more especially in Otago, has during the past summer been very limited, and, this being the case, the fact of the Government having taken the necessary steps for an exhaustive examination into the matter, with a view of ascertaining the best method of storage and delivery of the water-supply of the colony, will be very favourably received by those interested in mining. The report of the officer appointed for this purpose will be anxiously awaited by the miners interested. Having in view the fact that the water of the colony is one of its richest natural assets, and with a view of precluding the possibility of such a valuable asset being acquired by monopolists whose aim will necessarily be to derive individual profit from what should be for the common benefit, a series of suggested conditions, to be inserted in licenses issued in respect to reservoirs in which the storage of any considerable quantity of water is proposed and water-races for the distribution of large quantities of water, was issued for the consideration of Wardens. The suggested conditions are as follows: — Special conditions to be inserted in licenses for dams of large areas, granted subject to the following reservations in favour of Her Majesty the Queen, her successors, licensees, and assigns, and the conditions following, that is to say : — Besebvations. Eeserving— (a.) The full and free right for all and sundry, Her Majesty's liege subjects, who may now or at any time or times hereafter do so, lawfully to fish and to boat over the site of the dam within described. (b.) All fish now or hereafter being or placed in, upon, or about the site of the said dam. (p.) The full and free right for all and sundry, Her Majesty's liege subjects, to use the site of the said dam, and any Crown lands immediately adjoining thereto, as a place of public recreation and resort. (d.) The full and free right to all the water of the watershed of the site of the said dam. (<?.) The full and free right of Her Majesty the Queen, her successors, licensees, and assigns, and to all present or future holders of miner's rights issued pursuant to the goldfields laws of the colony for the time being in force, to discharge water-tailings and mining debris into, along, and upon the watershed of the site of the said dam, and through such watershed on to the said site itself, without being liable to any actions, suit, or other proceeding, or to any claim for an injunction made at the instance of the grantee, his executors, administrators, and assigns. (/.) The right to grant to any person or persons, or body or bodies politic or corporate, being the holders of such miner's rights as aforesaid, who shall be prepared to increase the storage-capacity of the said dam, the right to do all things that may be necessary to increase such storage, as well as to divert such a quantity of water as
152

may be warranted by such increased storage-capacity, but subject to such terms and conditions as the Warden may see fit to impose, but so that one of such terms and conditions shall be the liability either to pay to the grantee, his executors, administrators, and assigns, a proportionate part of the construction of such dam or such annual sum as shall amount to a fair and reasonable interest on the cost of such construction. Such interest not to exceed £5 per centum per annum by the year. Conditions. 1. That Her Majesty the Queen, her successors and assigns, may at any time resume the ownership of the said dam upon payment merely of the actual cost of any works of artificial construction actually performed by the grantee, his executors, administrators, and assigns, either on or in connection with the said dam, and without any further payment of any kind whatever. Such actual cost to be fixed in case of dispute by arbitration pursuant to the provisions of "The Public Works Act, 1894," or any statute amending or repealing such Act for the time being in force. 2. In the event of any such resumption, the grantee, his executors, administrators, and assigns shall be entitled to no compensation whatever in respect of any purely natural advantages of which he or they may get the benefit by reason of the within grant. 3. That if the grantee, his executors, administrators, and assigns shall at any time or times hereafter sell, let, or lease, or otherwise dispose of, all or any of the water stored in the site of the said dam to any other person or persons, or body or bodies politic or corporate, for use by such person or persons, or body or bodies politic or corporate, for all or any of the purposes mentioned in section 104 of " The Mining Act, 1891," the price per Government head per week at which such water shall be sold or otherwise disposed of, and the rental per annum at and the terms on which such dam and water, and any races to be hereafter constructed to carry such water, shall be let or leased, shall be fixed by the Warden or Wardens for the time being exercising jurisdiction in the mining district in which such dam and water-races may be situate; and such Warden or Wardens shall have further power from time to time to review, alter, and vary the said price and rental, as well as the said terms and conditions, either by highering or lowering such price or rental, or by varying such terms and conditions, or by making any order of review, alteration, or variation, either of general or particular application, and this notwithstanding anything contained or implied in any lease, agreement of letting or selling, or any other contract relating to the said dams, water, and water-races which may at any time or times be entered into between the grantee, his executors, administrators, and assigns and any other person or persons whomsoever, or body or bodies politic or corporate whatsoever, but so, nevertheless, that such Warden shall not exercise the power of reviewing, altering, or varying in this paragraph contained and reserved, either generally or in reference to any particular price or rental, oftener than once in every three years. 4. In fixing any price or rental or any terms or conditions either originally or by way of review, alteration, or variance the Warden shall be guided by what would be a fair value per week or per annum based on a comparison between the capital invested by the licensee on or in connection with the said water-race and the dams used in connection therewith, and the value of the return or the probable value of any returns from any ground proposed to be worked, having regard also to the hazardous and uncertain nature of the return from capital invested in mining operations. 5. That the grantee, his executors, administrators, and assigns do, within a period of twelve months from the date of the grant of the dam, or such extended period as the Warden aforesaid may from time to time grant, erect on the said dam a well- and efficiently-constructed dam-bank of ft. in length to the satisfaction of any engineer to be appointed by the Warden for the time being as aforesaid, so as to make such dam capable of storing million gallons of water at the least. 6. The grantee, his executors, administrators, and assigns shall pay all reasonable fees incurred by the Warden as aforesaid in appointing any such engineer to inspect the site of the said dam. 7. The grantee, his executors, administrators, and assigns shall, within a period of twelve months, calculated from the date of the grant of the dam referred to in the within grant, or within such extended period as the Warden aforesaid may from time to time grant, well and effectually connect such dam, by a siphon consisting of iron pipes, with the dam described in the certificate of registration therefor No. , and dated 8. None of the water stored or capable of being stored in the said dam shall be allowed to run to waste, and if such water is allowed to run to waste it may be the subject-matter of a grant by such Warden as aforesaid to any person of persons, or body or bodies politic or corporate, being the holders of such miner's rights as aforesaid. It is hereby declared that the foregoing reservations and conditions have been made in the public interest, and are both necessary and desirable for the public good within the meaning of section 129 of " The Mining Act, 1891." Special conditions to be inserted in licenses for water-races of large dimensions, granted subject to the following reservations in favour of Her Majesty the Queen, her successors and assigns, and to the conditions following, that is to say:— Reservations. Reserving— (a.) The full and free right for all and sundry, Her Majesty's liege subjects, who may now or at any time or times hereafter do so, lawfully to fish over and along the line of
0.-3
154
the water-race described in the within license and the waters at any time or times running therein and over any Crown lands immediately adjoining thereto. (b.) All fish for the time being in, upon, or about the line of the said water-race, or the waters at any time or times running therein. Conditions. 1. That Her Majesty the Queen, her successors and assigns, may at any time resume the ownership of the aforesaid water-race, as well as the waters authorised to be diverted thereby, upon payment merely of the actual cost of any works of artificial construction to be performed by the grantee, his executors, administrators, or assigns on or in connection with the said water-race, and without any further payment of any kind whatsoever. Such actual cost to be fixed in case of dispute by arbitration pursuant to the provisions of "The Public Works Act, 1894," or any statute amending or repealing such Act for the time being in force. 2. In the event of any such resumption, the licensee, his executors, administrators, and assigns shall be entitled to no compensation whatever in respect of any purely natural advantages of which he or they may get the benefit by reason of the within license. 3. That if the licensee, his executors, administrators, and assigns shall at any time or times hereafter sell, let, or otherwise dispose of all or any of the waters diverted by means of the waterrace described in the said license to any person or persons, or body or bodies politic or corporate, other than the licensee, his executors, administrators, and assigns for use by such person or persons, or body or bodies politic or corporate, for all or any of the puposes mentioned in section 104 of "The Mining Act, 1891," the price per Government head per week at which such water shall be sold or otherwise disposed of, and the rental per annum at, and the terms and conditions subject to, which such water and any races to be hereafter constructed by the licensee, his executors, administrators, or assigns to carry the same shall be let or leased, shall be fixed by the Warden or Wardens for the time being exercising jurisdiction in the mining district in which such water-race may be situate; and such Warden or Wardens shall have, further, the power from time to time to review, alter, or vary the said price and rental and the aforesaid terms and conditions either by highering or lowering such price or rental, by varying such terms and conditions, or by making any order of review, alteration, or variance either of general or particular application, and this notwithstanding anything contained or implied in any lease, agreement of letting or selling, or any other contract relating to the said water or water-race which may at any time or times be entered into between the licensee, his executors, administrators, and assigns and any other person or persons whomsoever, or body or bodies politic or corporate whatsoever, and so, nevertheless, that such Warden or Wardens shall not exercise the power of reviewing, altering, and varying in this paragraph contained and reserved, either generally or in reference to any particular price or rental, terms or conditions oftener than once in every three years. 4. In fixing any price or rental or any terms or conditions either originally or by way of review, alteration, or variance the Warden shall be guided by what would be a fair value per week or per annum based on a comparison between the capital invested by the licensee on or in connection with the said water-race and the dams used in connection therewith, and the value of the return or the probable value of any returns from any ground proposed to be worked, having regard also to the hazardous and uncertain nature of the return from capital invested in mining operations. 5. The licensee, his executors, administrators, or assigns will, within twelve months from the date of the within license, or such extended period as the Warden aforesaid may from time to time grant, well and effectually construct the water-race mentioned and described in the within license, so that the same shall be able efficiently and with reasonable safety to divert and carry a hundred Government heads of water. It is hereby declared that the foregoing reservations and conditions have been made in the public interest, and are necessary and desirable for the public good within the meaning of section 129 of " The Mining Act, 1891."
PRECIOUS STONES. Noeth Island. Opals have been obtained in the Tairua district. Mr. McKay, the Government Geologist, who has seen the stones and examined the formation, informs me that the opals are of a valuable kind, but that the method of obtaining them by blasting the rock tends to their destruction by shattering the stones. Mr. McKay also says that opals are present in the rhyolite formation in various places near the Ohinemuri River, and along the east coast, in a northerly direction, towards Tairua. Middle Island. In January last a license to prospect for opals was granted over the Mount Peel and Ackland districts, and subsequently the prospectors, being of opinion that their discovery warranted further development, formed the Record Reign Opal-mining Company, but operations have been retarded by the severity of the winter in the locality of the company's mineral lease, and no returns have as yet_been published. A number of other prospecting licenses have also been granted over the same districts.

MANGANESE- AND SULPHUR-MINING. The manganese-mines in the Whangarei district and at Waiheke Island have not been worked during the year. Messrs. John Chambers and Son, of Auckland, who are largely interested in the export of minerals, have supplied the following : — "Be manganese-mining: There has been no mining in this district during the last year, the activity in the gold-mining having taken off all the men from the manganese-mining, the wages being better and probably work easier. The European markets have been low all the year, the prices ranging from lOfd. to Is. per metallic unit delivered at Middlesboro or Lancashire, and, as the best only goes 54 units, there is not enough in it to encourage shipping. There has been a demand lately for it from Australia for chlorination and similar purposes, but we have not been able to get any to supply. We have shipped 340 tons of sulphur to Queensland lately, and there is a demand for more from New South Wales. The sulphur was obtained from deposits at Tikitere, Rotorua district. A contract has been entered into to ship 2,000 tons to Sydney at a very low price, about £3 per ton delivered. Our shipment and this one is coming from Rotorua. The Natives would much prefer the whole deposit to be taken over by the Government and worked for them, a royalty being charged. If we could have got any secure tenure for the sulphur deposits we could have arranged for the sulphur to be refined on the ground by a company, and the trade made into an important one, but as it stands now no one can put any money into anything of the sort."
PETROLEUM. Over thirty years ago the first bores were sunk at Moturoa, near New Plymouth, for petroleum, and since that time efforts have been made at intervals to secure payable supplies of the valuable mineral oil, of which ample indications abound. .Some three years ago a strong syndicate undertook fresh operations, and to date some 5,600 ft. have been bored in five bores, but it is considered that the bore, now 1,000 ft. in depth, at which operations are being carried on will have to be deepened at least another 1,000 ft. before strata of sufficient firmness is reached to enable the oil to bepayably worked. Many difficulties have been experienced, the water and mud in the bores being great drawbacks. On one occasion the derrick and boring gear was destroyed by a fire resultant on the gas igniting at a lighted lamp some distance from the bore. The manager states that some seventy barrels of crude oil of good quality have been raised by the syndicate, and found a ready market.
COAL-MINING. North Island. The output from the mines in the Kawakawa, Hikurangi, and Ngunguru districts is maintained, the coal being used by ocean-going and coastal steamers in Auckland, and by owners of steam-engines on the goldfields and other places along the east coast of the Island. Kawakawa Mine. —This mine is not likely to maintain an important output for more than another year unless fresh seams are opened. Hikurangi Mines. —The Hikurangi Coal Company have a large area of coal in their land, and a seam of considerable thickness is now being worked from the incline near the railway. The West Bryan's and Phoenix Mines both have connections with the railway, and the mine-trucks can be emptied into the railway-wagons. Rolleston's Mine is also being worked, and can be connected with the railway at a moderate cost. These mines, if necessity should arise, will be in a position to double or treble their output. Waikato Mines. —The Waikato Mine has still continued to maintain a profitable yield. The Taupiri Reserve and Taupiri Extended Mines are both working on large seams, and could considerably increase their output, but any great additional demand is not to be expected until direct railway communication is effected with the Thames and Waihi, when the coal, as well as the slack, will be in request for steam and other purposes on the Hauraki Goldfields. Mokau Mine. —lncreased attention is being directed towards opening up this mine. The bar at the mouth of the Mokau River will, however, be always an obstacle to the success of this mine, as only very small steamers can cross the bar and be taken up the river to the mine. It is therefore apparent that until railway communication with the Mokau district is effected the coal deposits cannot be worked to any great extent. Middle Island, Nelson District. Collingwood. Prospecting has been carried on in a new lease taken up by Messrs. Taylor and Walker, at Puponga, in the vicinity of Cape Farewell, and about sixteen miles from Collingwood. The Pakawau Mine still continues to be worked, but operations have been completely suspended in the Wallsend Mine. Nelson. The Enner Glyn Mine is being further opened up by a shaft sunk 160 ft. in the rock. A stone drive will be put in from this depth to cut the seam and connect with the workings from the other shaft. 21—C. 3.

Westport District. Mokihinui Mine. —The workings were carried on in the area opened by the new incline. The seam is, however, much disturbed in this section, and operations have been stopped. The Hut seam has latterly been worked. The coal-in this is better, as it is not intersected with stone veins to such an extent as in the old workings on the big seam. Eorty-four men were employed. Cardiff Mine. —This colliery has been conducted with profitable results ; the coal is of a superior quality, and commands a ready market. The output for the year was 40,431 tons, and seventy-eight men were employed. Granity Greek Colliery. — Since the preliminary work and erection of tramway was completed in the early part of the year a steady output has been maintained. Ninety-two men were employed. The mine is well equipped. All shots are fired by men specially appointed for the purpose. Two coal-cutting machines, driven by compressed air, are now at work ; one is a Stanley headingmachine, which cuts two annular grooves in the coal each 5 ft. 6 in. in diameter; the other cutter is of the percussion type, and is used for holing. It appears to work satisfactorily, and relieves the miner of the most dangerous part of his work. The manager, Mr. Brown, states that these machines will not displace any labour, but that a somewhat greater output may be expected from the same number of men, with less liability to accidents from falls of coal when holing. The output since work on the coal commenced was 20,543 tons. Coalbrookdale Colliery. —This mine, as well as the Granity Creek, is owned by the Westport Coal Company. The Iron Bridge Mine is also worked and owned by this company. The tramways and methods of conveying the coal to the railway are the most extensive in New Zealand, and the company are now in a position to supply all demands for their coal. The output for last year was 190,975 tons of coal from Coalbrookdale, and from Granity Creek 20,453, making a total output of 211,328 tons. Of this, 10,000 tons of Coalbrookdale coal was exported to San Francisco, Valparaiso, and other ports, chiefly by sailing-vessels. Coal-cutting machines are also to be adopted in this mine. A very extensive output can be maintained. During the year 315 men were employed at this mine, and now that direct foreign export is established there is evidence that the trade will largely be increased. The other mines, in Longford, Boatman's, and Reefton districts, maintain a sufficient production to meet local demands. Grey Biver and Grey Valley District. Blackball Colliery. —The coal from this mine still meets with a fair demand, the output for the year being 45,722 tons, an increase of 2,667 tons compared with that of last year. Ninety men were employed in connection with this mine. Brunner Mine. —The mine has produced a return which is only 7,491 tons less than the output of last year. The coal was chiefly derived from pillar- workings. The disastrous accident which occurred in March, 1896, whereby sixty-five men lost their lives by an explosion in the mine, naturally led to time being taken up in the recovery of the bodies and the necessary repairs to the workings. The decrease may be thus accounted for. In the Brunner Rise Mine, which is owned by the same company, the workings were more in the solid, but latterly, as the coal was thinning out, pillarwork was also resorted to. The company have also been constructing a railway to the coal lease owned by them in the direction of the Seven-mile Creek. This line cannot be completed until the erection of the bridge over the Grey River is finished. The output for the year for the GreymouthPoint Elizabeth Company was 92,118 tons, and the number of men employed 213. The facts connected with the explosion that had such serious and disastrous effects have already been so fully elucidated at the inquiry held by the Commission that it is not my intention to further report on the matter. Efficient precautions are now taken at the mine. The blasting is done by roburite fired by electricity, the persons appointed as shot-firers always examining the places before any charges are exploded. The use of safety-lamps is also enforced on all those working underground. Canterbury and Otago Districts. In consequence of my recent appointment, and pressure of other official duties, it has been impossible for me to visit either the Canterbury or Otago coal-mines, but from the returns furnished by the mine-owners it will be seen that the output continues to improve in many of the mines, more particularly in Otago, where the local demands for use in the boilers of the dredges and other mining machinery are increasing rapidly. -In the Malvern district the Home Bush, 3,164 tons, Springfield, 2,680 tons, Mount Somers, 2,018 tons, and Whitecliffs, 1,701 tons, were the chief producers. In North Otago the Shag Point, 21,097 tons, and Allandale Mines, 11,455 tons, stood highest on the list. In South Otago the Kaitangata Mine had an output of 72,536 tons, being an increase of 8,679 tons on the return of the previous year. The Castle Hill Mine's output was 12,825 tons; the Walton Park showed a slight increase, the return being 16,612 tons. In Southland the Nightcaps Mine yielded 16,905 tons. In the above districts a large number of small mines and pits yield an ample supply to meet local requirements. The Phenomena op Colliery Explosions, by Donald M. D. Stuart.* The subject of colliery explosions has engaged the attention of mining engineers for nearly a century, and experience and science have devised many precautions, with the result that the

number of disasters have been greatly reduced during each succeeding decade. Explosions, however, still occur in the best-arranged collieries, showing that there are some phenomena not yet fully recognised and understood ; and, with this fact as a justification, the author ventures to offer this paper to the members. The author had the advantage of investigating the first and second recorded explosions in mines that yield no fire-damp —viz., the disasters at the Camerton and Timsbury collieries, Somersetshire, in November, 1893, and February, 1895, respectively. These disasters provided opportunities for observing the phenomena of two explosions not complicated by the presence of fire-damp. They exhibited the effects produced by an explosive agent, and therefore pronounced its identity, as every agent is identified by the phenomena it produces. The records have this value : They demonstrate that explosions are produced in mines by gases derived from coal-dust, and that the processes are originated under ordinary working conditions and operations; they also disclose the phenomena which identify explosions from this agent. The effects of the disaster at the Camerton collieries were visible from the point of origin for 828 ft. towards the coal-faces, and for 3,714 ft. in the opposite direction, towards the downcast shaft. The phenomena were equally clear at the Timsbury collieries from the seat of origin to the upcast shaft, a distance of 2,900 ft., and into the several districts that branched off at intermediate points. In the paths of the explosions there were occasional exhibitions of destruction, where men had been exposed to violent forces —trams of coal hurled off the rails, crumpled up, and their contents scattered abroad; empty trams broken, the roof ripped down in large falls, timber structures reduced to matchwood, and wrought- and cast-iron fittings and pipes torn or broken to pieces. These scenes of destruction were separated by intervals varying from 114 ft. to 1,030 ft. in length ; and in the intervening spaces the men have suffered no violence, trams of coal were standing undisturbed, the empty trams were uninjured, the timber and fixtures were in their normal positions, and the iron fittings and pipes were not damaged or displaced. The phenomena of explosive violence at distinct points along the paths of the explosion, and the positive absence of such phenomena in the intervening spaces, demand for their explanation distinct modes of energy. An examination of the local disturbances in parallel passages showed that the materials were displaced in opposite directions ; and, where the destruction occurred at junctions, the wreckage was distributed in the entrance of each road. The positions occupied by the displaced materials indicated the exertion of explosive forces from a common centre, and exhibited the phenomena that must arise in a gaseous explosion, in which disruptive forces are necessarily exerted in radial lines, hurling movable objects in all directions around the gaseous body within a local area. The evidence in the disturbances and in the spaces between them left no room to question the occurrence of distinct local disruptions along the paths of the coal-dust. Between the points of origin and the first disturbances there were considerable lengths of road in which the men were found who fired the originating shots, also their cotton food-bags, loaded and empty trams, and timbering. The men had suffered no violence, not a bone was broken, nor their clothing disturbed, the food-bags were still hanging from the roof by cotton tapes, the loaded and empty trams were alike undisturbed, and the timber standing in its ordinary position. Consequently, there could not have been either explosive violence or a rapid gaseous movement between the shots and the first disturbances; the distances were 408 ft., 420 ft., and 573 ft. respectively; and this undisturbed condition of road was repeated between every propagated explosion. The author numbered the local explosions for facility of reference, and, referring to the disaster at the Camerton collieries, he observed six loaded trams of coal in the road between No. 5 and No. 6 explosions, which threw some light upon the gaseous movement in the interval of 492 ft. that separated these propagated explosions. The trams have an open end, in which lumps of coal are built up, and this wall of coal in the last tram faced the emergent gases of No. 5 explosion. About 60 lb. of this exposed coal, in lumps of J lb. to 4 lb. or 5 lb. each, had disappeared. If the coal had been removed by mechanical force the lumps, or their fragments, must have been present somewhere in the road, but the author could not discover any trace of them. He, however, observed heavy deposits of coked coal along the opposing faces of two rods or collars (6 ft. long each) fixed next to the roof, almost immediately over the tram referred to. This coke and some fine carbon were the only visible remains of the missing coal, which had evidently been reduced to globules of coke by gases at an exalted temperature. Had there been a great velocity in the horizontal movement of the gaseous body that attacked the coal the particles of coke must have been swept along as they were produced, but they ascended almost vertically to the faces of the overhanging timber, and were deposited there, indicating a comparatively slow onward movement of the gaseous body, and showing that the disruptive forces of No. 5 explosion were expended in the immediate vicinity of their production—about 120 ft. from the tram of coal. In a stall at the Timsbury collieries, about 210 ft. from No. 6 explosion, a tram of coal was found undisturbed upon the rails, the blocks of coal standing from 15 in. to 18 in. above the woodwork, the top surface reaching a height of 4 ft. above the floor. The hard faces of these blocks of coal all round the tram had been made to burst out into globules of bituminous matter, which underwent further destructive distillation, leaving residues of comminuted coke. Some globules remained attached to the faces of coal in different stages of production, and every ledge of coal, the edges of the woodwork of the tram, and the buffers were loaded with accumulated particles of coke resembling small shot or coarse sand. These particles of coke did not ascend to the roof, but gravitated down to the resting-places where they were found, showing an inadequate horizontal movement in the gaseous body that attacked the coal to carry the particles forward; and that the disruptive forces in No. 6 explosion, which were necessarily of an enormous velocity, were also expended in the immediate vicinity of their production.

Another observation upon the air-current at the Camerton collieries adds to this part of the subject. Between the point of origin of the disaster and the downcast shaft there were seven violent disturbances, in several of which the falls were each estimated to measure from 600 to 800 tons of rock and shale. These falls were in the main-intake airway, the last one being 2,838 ft. from the downcast shaft, and the road for this distance approximated to a straight line. During the occurrence of the explosion the onsetter was standing at the bottom of the downcast shaft, and neither felt nor heard anything unusual. He observed that the flame of his open light was momentarily reversed towards the shaft, but insufficiently to arouse a suspicion that anything was wrong. Another man was standing in the intake at an intermediate point 1,848 ft. from No. 10 explosion, and he did not feel or hear anything of the explosions beyond a puff of wind that put out his candle; he attached no importance to this, as it often occurred, the air-current travelling at a high velocity. The absence of appreciable mechanical force in the movement of the atmosphere between the shot and the first disturbances in the spaces between the successive disruptions and at the end of the propagations, with the phenomena of intermittent exhibitions of explosive violence, amount to demonstration that a series of local explosions occurred at the loci of the disturbances, in which disruptive forces were exerted in all directions and expended in their immediate vicinity. The foregoing phenomena in the atmospherical movement admit the element of time antecedent to each disruption for the destructive distillation of the coal and the production of the explosive gaseous mixtures, to the ignition of which the local explosives were due. The author has therefore described the lengths of undisturbed road that are observed antecedent to each explosion as gas-generating spaces. Observations made at the loci of the disruptions disclosed the fact that they occurred at the junctions and sidings, where large cavities existed in the roof, at sharp angles in the road when the path of the explosion was against the air-current, and where a door formed a cul-de-sac. One condition common to these loci was a larger provision of atmospheric oxygen than could be obtained in the antecedent spaces. Another branch of evidence was the deposition of coked coal upon the timber, trams, and floor of the workings, which appeared to be deposited in these places under special conditions, and not in the general progress of distillation. In the immediate vicinity of the shot at Camerton collieries the floor was covered with a crust of coke, and the faces of the timber fronting the shot were thickly coated with coke to a height of 12in. above the floor; above that point there was very little deposit. At Timsbury collieries a tram was standing between No. 4 and No. 5 explosions, from which the author took the following observations : Tram loaded with shale, standing upon the rails, had not been disturbed. Coked coal-dust upon the end facing the course of the explosions. The buffer-ends, measuring 12 in. above the floor, covered with coked coal-dust fin. thick. Many patches of coked coal upon the wooden end of the tram, thinning off to nothing at 21 in. above the floor, the upper 9in. of the wood being clean. No trace of coke upon the angle-irons, draw-bar, link, wheel, or axles, nor upon any other part of the tram. An obstruction in the path of the explosions will therefore retain a deposit of coke if it present a surface at the necessary height to which intumescent coal-dust can adhere. The evidence at this tram, which is confirmed by many other observations, shows that the coal-dust upon the floor is subjected to distillation, the particles rising to a height in this case of 21 in. The coal-dust on the sides and the upper parts of the timber is, no doubt, attacked by the hot educts; but in the intervals between the explosions the author observed coked coal near the roof in one place only, and that was at a sheltered flank which had flakes of coked coal lying.upon it. In the vicinity of explosions coked coal was observed upon the opposing faces of timber on opposite sides of the disruptions, and it is not difficult to conceive how the hot, pasty coal-dust would be projected against these opposing surfaces by the forces of the explosions, which moved in radial lines. Where propagations were arrested, with small coal left in suspension in a semi-distilled condition, it is also conceivable that with the atmosphere in front at normal or greater tension, and the atmosphere behind in an attenuated condition, due to the chemical changes that had taken place, the suspended pasty coal would retreat, and be deposited on the faces of timber, contrary to the course of the explosions; and this deposition was observed at Timsbury collieries. The deposits of coked coal on the timber lying next to the roof over the tram between No. 5 and No. 6 explosions at Camerton collieries will present no difficulty when it is known that the distillation was going on in the face of the incoming air-current, and consequently the chemical action was energetic, and the globules of coke were carried upward with the educts. The comminuted coke at the train beyond No. 6 explosion at Timsbury collieries was in a receding air-current with the supply cut off; hence only a small quantity of coal was distilled, and the action was not sufficiently vigorous to carry the globules of coke in resistance to gravitation. The positions in which the deposits of coked coal were found are explained by the hypothesis of local explosions with antecedent gas-generating spaces, and the condition of the air-currents. Observations were made upon the nature of the atmosphere that filled the workings after the disasters. The roads had collapsed locally at many of the disruptions, and the circulation of air was suspended. The products of the gaseous explosions with the residual gases filled the roads in the fields of disaster, and were imprisoned between the falls, forming a series of still atmospheres that could only be displaced by diffusion until the final obstruction was reached and removed and the circulation of the air restored. The exploring parties frequently advanced into the stagnant atmosphere more rapidly than diffusion was effected to make apertures through the falls, and had favourable opportunities of observing the effects of this atmosphere. Their open lights burned brightly, and disclosed the absence of the small percentages of carbon-dioxide and of the inflammable gases that are appreciable

by the ordinary tests; but they suffered physiological sensations that ended in unconsciousness. They observed the atmosphere laden with particles of soot, and compared it to the condition produced by " turning a bed-tick inside out and shaking it in the air." The author observed that this suspended matter had been universally deposited upon the walls and timber of the roads throughout the fields of disaster, and, upon examination, found it to be amorphous carbon, such as may be obtained by burning hydrocarbons in limited quantities of air. The carbon obtained by holding a glass rod in an illuminating gas-flame, and the compact form of the deposit, are well known; the carbon at the Camerton and Timsbury collieries proved, upon investigation, to be the same in substance, but differed in the form of deposition. In numerous places in the mines the carbon upon the timber and strata was in gossamer-like form, and gave the surfaces a veined appearance. The author collected these striated filaments upon paper ; but, however carefully preserved, they broke down into powder under the slightest pressure. The general deposit was a loosely-built-up and dilated stratum, which, when touched with a flat surface, shrank to a fraction of its original thickness. It was obviously the accumulation of successive settlements of particles originally in atmospheric suspension, and that condition of the atmosphere in the mines immediately after the disasters is a fact of observation. These depositions of carbon were therefore distinct in structure from the deposition that arises from the impingement of a hydrocarbon flame upon a cold surface. The origin of this carbon is not far to seek : the residues of coked coal already referred to are the evidence of distillation, showing that hydrogen and gaseous hydrocarbons flowed into the atmosphere of the workings; and these hydrocarbons provided the amorphous carbon, of which it formed the solid constituent. The separation of this carbon of the educts involves questions in thermo-chemistry which cannot be dealt with in this paper beyond saying that the processes that caused its separation were the sources of heat upon which the explosive phenomena depended. The author suggests the following theory to explain the phenomena now recorded : The products of the mining powder with their unexpended heat were projected through the planes of ruptured strata in fan-like sheets, striking the coal-dust on the floor, and setting up destructive distillation. The educts flowed into the atmosphere of the mine, but could not undergo explosive combustion, although an ignition temperature was at command, because the atmospheric oxygen was inadequate, or not within reach to make an explosive mixture. In the loose dust and debris and in interstitial spaces there was necessarily some oxygen, which would be seized by the free hydrogen, and by the hydrogen constituent of gaseous hydrocarbons in the educts, its oxidation liberating the carbon of the latter in solid form to float in the atmosphere. The temperature reached by the oxidation of hydrogen being about 2,000° Cent., and there being a large quantity of heat generated in that process, the remaining hydrocarbons that had not previously undergone change would at that temperature, and in the absence of atmospheric oxygen, undergo dissociation, placing free hydrogen at disposal for disruptive action where oxygen could be obtained, and leaving more of the fine carbon in atmospheric suspension. A series of chemical actions of constant sequence was therefore established in the immediate vicinity of the shot, in which there was the partial oxidation of hydrogen referred to generating heat, which instituted a series of chemical changes identical with those which the heat supplied by the products of the mining powder had originated, and these regenerative activities were of constant and similar reproduction along the path of the coal-dust, free oxygen undergoing constant accumulation, until a place was reached in the workings where the available quantity of air was greatly increased, and, the partial combustion taking place, the accumulated hydrogen was oxidized with explosive violence, causing the disruptive effects observed at the loci of the initial local explosions. The quantities of heat generated in the initial local explosions greatly exceeded the total quantity of heat in the products of the mining powder, and it will be readily understood that an advancing series of similar changes to those described was again established in the coal-dust beyond, producing secondary explosions at points farther away, where the conditions for the oxidation of the accumulated hydrogen were fulfilled; consequently, the explosions would be propagated along every path of the coal-dust, so long as atmospheric oxygen was available, and there were no wet spaces to bring down the temperature. This theory satisfies the demand for chemical changes, causing a constant regeneration of heat, and places an explosive gas at disposal for disruptive action without the production of carbonmonoxide or carbon-dioxide, and which did not yield these gases as products. It accounts for the practical absence of carbon-monoxide and carbon-dioxide from the atmosphere in the fields of disaster with the fact that the carbon constituent of the hydrocarbons was not oxidized, but disseminated in the atmosphere, where it was found in copious suspension by the exploring parties, and from which it had been deposited upon the vertical faces of the enclosing walls in dilated layers and in striae, giving the faces of stone and timber the veined appearance already referred to. It is not difficult to understand why there was an absence of mechanical effect upon the ventilating-power at the Camerton collieries when it is remembered that the gaseous hydrocarbons that were heing constantly added to the atmosphere of the mine were almost immediately eliminated by the oxidation of the hydrogen constituent, and that the volume of the incoming air was being constantly diminished by the removal of its oxygen, forming one-fifth of that volume for oxidation of the hydrogen in the explosions and antecedent actions in successive productions of steam, undergoing eventual liquefaction by surrender of heat, and that by means of this exhaustion the mechanical equilibrium of the air-current was maintained. The terminations of the explosive phenomena admit of explanation. Propagation of the explosions was observed to have been abruptly arrested in roads where dry coal-dust abounded, and at these places observations disclosed the presence either of coked coal-dust or amorphous carbon, indicating chemical activity that supplied heat and ignition temperature. The absent factor in the
C.—3
160
explosive cycle was therefore atmospheric oxygen, and the condition of the air-currents confirmed the conclusion. Propagation failed because the chemical actions languished to extinction, due to an inadequate supply of atmospheric oxygen for the oxidations which yielded heat to carry on the distillation and other chemical changes. The fundamental difference between the path of propagation and the path in which propagation failed was in the condition of the air-currents. In one very small " split " and in return air impoverished of its oxygen the chemical processes were observed to be arrested. Propagation was also arrested in wet places, and is explained by the fact that the product of the oxidation of hydrogen would by its contact with wet surfaces undergo a change corresponding to what takes place in the condenser of a steam-engine. The external stratum of the product coming in contact with the cold wet surfaces would be instantly condensed, leaving a vacuous space into which another stratum would fall and be condensed, and the process would be repeated so rapidly during the slow gaseous movement as to make condensation practically instantaneous. The product being liquified by surrender of heat, the temperature would fall below the distilling point, and the chemical actions come to an end. The disaster at the Timsbury collieries originated in the main intake air-way; and, while the disastrous effects that are identified with a colliery explosion were produced from the shot to the upcast shaft on one side, there were no such effects from the shot in the opposite direction towards the downcast shaft. Observations, therefore, show that had the condition of the air-way from the shot towards the downcast also prevailed from the shot towards the upcast shaft the disaster would not have happened. The difference between the two portions of the air-way was as follows :On the upcast side it contained the full circulating current of air, which at the time of the disaster was about 13,000 cubic feet per minute, and the coal-dust was dry ; on the downcast side it contained the same circulating current for a distance of 150 ft.; at that point the ventilation entered the intake from a side road, but 525 ft. beyond a door was fixed, and the air between the side road and the door was a still atmosphere. The coal-dust was more or less damp or wet at the side road, and wet up to the door. The still atmosphere was laden with water-vapour to saturation. At the Camerton collieries the coal-dust was equally dry on both sides of the shot, and disastrous effects were produced in both directions. The propagation against the intake air-current; after being active for 3,714 ft., causing great destruction, was abruptly arrested at 2,838 ft. from the downcast shaft. The atmosphere at this point was the main intake air-current in which the 3,714 ft. of propagation had occurred, and the author made the following observations of the condition of the road where the propagation was arrested, commencing in the vicinity of the last, or No. 10, explosion : — Ft. Ft. Archway and fall, floor and sides dry and dusty ... ... 90 Water and mud on floor, no dust ... ... ... ... 66 Floor damp between the rails, damp dust outside of rails ... ... 24 Last fall, floor and sides damp, no dust ... ... ... ... 21 Water and mud on floor, sides wet, no dust ... ... ... 48 — 159 Floor damp between rails, intermittent wet spots, dust outside of rails damp to dry ... ... ... ... ... ... 234 Floor and sides damp and muddy ... ... ... ... 24 Floor and sides dry and dusty to horse-guy ... ... ... 261 519 The effectiveness of wet lengths of road in stopping the propagation of an explosion is a fact of observation, and air saturated with water-vapour must, in the nature of the case, be a valuable contributory precaution. The arrest of propagation is consequently brought about by atmospheric conditions in which heat cannot be generated for the reproduction of the distillatory and other chemical actions, because the supplies of atmospheric oxygen are inadequate ; also by wet surfaces, which demand the surrender of the heat for the evaporation of their moisture. Most of the principal phenomena of the disasters at the Camerton and Timsbury collieries have now been referred to, and the theory which the author has advanced upon his records and investigations may be shortly stated as follows : A colliery explosion in which coal-dust is the principal agent comprises numerous local explosions separate in time and in space, at irregular intervals, where the available supplies of atmospheric oxygen are greatly increased and caused by the explosive combustion of hydrogen derived from the coal-dust in the antecedent spaces by a series of chemical actions of constant sequence, which produce heat for regeneration without auxiliary intervention, and are constantly reproduced along the path of the coal-dust under the conditions named. This theory accounts for the coked residues of coal and the positions in which they were found ; explains the presence of amorphous carbon in atmospheric suspension, and its characteristic deposition upon the enclosing walls throughout the fields of disaster; accounts for the practical absence of carbon-monoxide and carbon-dioxide in the gaseous products; supplies the heat for the distillatory action, for dissociation, for raising the air of the gaseous mixture to ignition temperature, and for supplementing the losses due to the contact of the products of combustion with cold surfaces; allows time for the distillation of coal, and the chemical changes in the series of actions; provides the explosive gas for producing the disruptions; explains the occurrence of the disruptions at intervals ; the absence of mechanical effects in the intervening spaces, the conditions under which propagation proceeds or is arrested, the maintenance of the mechanical equilibrium of the air-current at Camerton collieries, and excludes no coal, except that which yields no combustible gases when subjected to the temperature of destructive distillation.

TIMBERING IN COAL-MINES. The following is taken from a report of a lecture delivered by Mr. H. W. Halbaum on the above subject before the Midland Branch of the National Association of Colliery Managers, at Derby, on the 28th November :— The lecturer said the importance of the subject was very often overlooked. They were apt to consider that fire-damp and coal-dust were the great enemies of the miner, but that was not so. If they looked through the Inspector's reports for the last ten years they would find in that district twelve miners had lost their lives through explosions, but through falls of roofs and sides no less than 329 lives had been lost. Last year in the United Kingdom fifty-five persons lost their lives by explosions, and 426 lost their lives through falls of roof and sides. In the Midland district five persons were injured by explosions, but 570 were injured through falls of roofs and sides. In the United Kingdom 215 received serious injury through explosions, but 2,023 persons received serious injuries through falls of roofs and sides. He wanted to impress upon them that that subject was not only a very important one from the point of view of safety, but also from an economical point of view, and anything which tended ' towards an economical working of coal-mines —the staple industry of this country—ought to have their best consideration. The item of timbering was one of great expense in all coal-mines. It was one of the chief items of expense, and it was a fortunate colliery where timber only cost 2d. per ton of coal raised. He had heard of collieries where the cost had amounted to Is. 6d. per ton of the coal raised. The proper and improper use of timber very often meant either paying a dividend or a serious loss. They had always to be liberal with timber, but there was no reason why liberality should degenerate into waste. He had found that economy went always hand-in-hand with safety, and waste of timber only meant increased danger to the miner. That day he only intended to deal with the subject of timbering so far as it affected the pit-prop. The first thing they had to do was to choose the timber, and the question was a very important one, because bad timber involved danger of life and limb to hundreds of their fellow-workers. They knew when they had a long wall-face, roof, and floor coming together, and what the pressure was that caused this movement. In a mine 500 ft. deep the pressure was somewhere about 1,6001b. to the square inch, and whatever kind of timber they used could not resist that pressure. The maximum pressure and the strength of the whole body of strata were coming down; but the object ought to be not to resist the maximum pressure, but to sustain the loosened fragments which so frequently dropped out. Nothing could resist the maximum pressure. What was wanted was timber props possessing the greatest elasticity, which would bend to the maximum pressure, yet sustain the loosened fragments. Rigid creosoted props were very dangerous. Steel was the typical material for props, because it had great strength with great elasticity, because it would bend to the maximum pressure and sustain at the same time the loosened fragments. It was not unlikely that the use of steel would become common. Science had triumphed over so many obstacles that the difficulties in the way of using steel did not appear insurmountable. The main difficulty was the expense and the recovery. Mr. Halbaum went on to deal with the various modes of propping in seams of different height, but said the system which answered at one colliery would not answer at another. Larch, fir, and the different orders of pine he recommended as the best kinds of timber, as they possessed the most elasticity. With regard to the props to be used in seams of different heights, in tall seams the maximum pressure was greater in proportion, and its effect was irresistible. In a seam 6 ft. high the roof would descend 2 in., where in a seam 3 ft. high it would only descend 1 in., and the size of the prop should be increased in proportion to the height of the seam. The strength of a prop increased with the square of its diameter, though if a 3 ft. prop, 3 in. in diameter, had to be put in a 3 ft. seam a 6 ft. prop in diameter was more than sufficient for a 6ft. seam. If they increased their props more than was necessary they wasted timber and infringed upon safety. That part of his subject was one which he should like to see thoroughly investigated by their mining institutions. The strength of timber in ratio to its length and diameter was a very important subject; and then there was the question of knots and other details. The next question was the nature of the roof. The stronger the roof the stronger ought the timber to be. Most of the accidents which happened at the face happened under strong roofs, because they were apt to take liberties with them, and the miner trusted the roof too far. Strong roofs broke into larger fragments, and that was another reason why they required strong props. Again, strong roofs transmitted the maximum pressure more heavily to the timber. The worst roof they could have was a hard pannelled one, a strata of sandstone with a layer of soft shoal above it, which could only be supported by chocks of steel and big timber. The next point was the care of the timber, and that was also one of the highest importance. The prop was simply a collection of fibres which they could tear in pieces. The lecturer went on. to explain the nature of the prop, and said their duty was to take care of every one of the fibres to preserve their strength and elasticity. They ought to be kept at the surface under cover, properly stacked and ventilated, and preserved from all vermin. The timber required protection from atmospheric forces; the floor on which it was stacked ought to be raised from the ground, and under no circumstances ought to be left lying about the yard. He was strongly against the use of creosoted or salted timber, because it was too brittle, and snapped like cast iron. Mr. Halbaum went on to explain the different modes of timbering, by means of diagrams. He said that nine-tenths of the accidents happened because they had had good roofs behind them, and they always expected good roofs in front. The majority of accidents could be prevented by putting timber in in time, and with a proper knowledge of how to put it in. The props ought always to be put in squarely and firmly in the line of pressure. That was one of the fundamental principles of timbering. If they put timber in in the direct line of pressure they put in what was known as the resultant force. They should set their timber in the same straight line as the line of gravity.
C—3.
162
The line of gravity was not always the line of pressure. In a steep seam all the timber should be set at right angles to the plane of stratification. The props should always be set so that the pressure upon them should be distributed evenly over the surface, that every fibre should receive its fair share of the load. Mr. Halbaum also briefly touched upon the advisability of having lids on the props, but spoke against nails being hammered into them. In conclusion, he again referred to the great importance of the subject, which he hoped would in the future receive more consideration from their mining institutions. They had recently in one course had three papers only on timbering and fifteen on fire-damp and coal-dust, but he hoped that before long the subject of timbering would receive the attention that it deserved. The above report is taken from the Mining Journal.
HYDRAULICS. The following instructive papers on hydraulics, written by Mr. Alexander Aitken, manager of the Government water-races at Kumara, who has carried out experiments for the purpose of verifying the calculations therein set forth, will be found of considerable service to those interested in hydraulic sluicing and elevating : — Power op Water. The following short method of calculating the practical horse-power of water that can be realised by various water-motors is based on the fact that one sluice-head of water falling 8-8 ft. is equal to 1 theoretical horse power. A sluice-head of water is 1 cubic foot of water per second, or 60 cubic feet per minute. A cubic foot of water weighs 62f1b., therefore a sluice-head of water delivers 3,7501b. of water per minute. This multiplied by 8-8 ft. gives 33,000 foot-pounds, or 1 theoretical horse-power : — 60 x 62-5 x 8-8 = 33,000 foot-pounds = 1 horse-power. Table No. 1 shows the approximate percentage of the theoretical horse-power of water actually realised by various water-motors. Table No. 2 gives the hydraulic head necessary to obtain 1 effective horse-power from one sluice-head of water with motors that can practically realise from 30 to 100 per cent, of the theoretical power of the water, but no motor has yet been constructed that will realise much more than 90 per cent, of the theoretical power of water. The hydraulic (or hydro-dynamic) head of water is the total vertical height of the supply above the point of discharge, after due allowance has been deducted for friction and other retarding forces in the pipes (or other conduit) delivering the water to the motor. Total head, minus allowance for friction, &c, equals hydraulic head. If pipes are large enough to convey the required quantity of water to the motor at a velocity not greater than Ift. per second, and the length of the pipe-line is not great, allowance for friction, &C, is not necessary, and the total head may be taken as the hydraulic head. If, however, the pipes are small for carrying the required quantity of water, and the velocity of the water is from 3 ft. to 20 ft. per second, the allowance for friction, &c, cannot be disregarded, as it may in some instances where the pipe-line is long absorb the whole of the total head, and only deliver the water without being capable of developing any power. Pipes conveying water for power cannot be too large, the only limit being the practicability and the cost. For determining loss of head by friction, &c, consult instructions and table prepared for that purpose. Table No. I. — Percentage of Theoretical Horse-power realised by Various Water-motors.

To obtain the highest efficiency the motors must be suited to the quantity of water used and properly constructed. The manner in which the water is supplied and the regulation to the proper speed are matters of the utmost importance in obtaining good results. The correct speed for the periphery of a Pelton wheel is one-half the speed of the water issuing from the nozzle. The high efficiency of the Pelton wheel is due to the very perfect manner in which it reverses the direction of a. jet of. water,.discharging .the water almost without motion.

The more complicated rules given in Gordon's " Miners' Guide," " Molesworth," and other works on hydraulics produce the same results as in the above examples. Calculation of the Carrying-capacity of Open Channels, Tunnels, and Flumes by Eytelwein's General Formula. " The mean velocity of water in feet per second equals the square root of twice the fall in feet per mile multiplied by the hydraulic mean depth in feet." And velocity ;multiplied by area equals quantity. The hydraulic mean depth is the sectional area of flowing water divided by the wetted border. The area is the mean width of the flowing water multiplied by its depth. The wetted border is readily found for plumb or sloping sides by the following rules:— Plumb sides ... ... ... ... Depth x 2 -f width of bottom. Jto 1 sides ... ... ... ... Depthx2-0615+ „ jto 1 sides ... ... ... ... Depthx2-236 + Ito 1 sides ... ... ... ... Depth x 2-828 + Example 1. What quantity of water will a channel with J to 1 sides carry, 4 ft. wide at bottom, 2 ft. 6in. depth of water, and having a gradient of 12 ft. per mile? (2-5x2-0615) = (5-15375)+4 = 9-15375 = wetted border. 5,25 2 + 4 = 4-625 = mean width. 4-625 x 2-5 = 11-5625 = area. 1 1|||? = 1-2631 = hydraulic mean depth. ■ •s/24 x 1-2631 = 5-5058 = velocity in feet per second. 5-5058 x 11-5625 = 63-66 = quantity in cubic feet per second. The number of cubic feet per second (or sluice-heads) of water which such a channel will carry, if long, straight, and smooth, is 63-66, but for other kinds of channels the result must be multiplied by coefficients suitable to the character of the channels, as a crooked and rough ditch or tunnel through boulders and stones, or with sets of timber every 3 ft. or 4 ft., will only carry about 40 per cent, of that quantity. The following table of coefficients for flumes, tunnels, and channels is deduced from a large number of experiments extending over a period of twenty-five years:— 1.

Velocity is proportional to square root of gradient. / H.M.D. „ „ gradient x H.M.D. Friction of Water in Pipes and Channels. Experiments show that the forces that retard the flow of water in pipes and channels, all of which are generally included in the term "friction," are in pipes and channels of the same character and of equal hydraulic mean depth proportional to the square of the velocity of the water, but where the H.M.D. is greater the loss of head by friction is less for any specified velocity. A velocity of, say, 10 ft. per second in a small pipe produces more loss of head than the same velocity in a larger pipe, because the fictional surface in proportion to the area is greater in the one case than in the other. In the conveyance of water through pipes or in channels a portion of the head lost is absorbed in producing the velocity of the water ; another portion is absorbed by friction proper ; and another portion (in many instances very large) is absorbed by eddies and counter-currents, caused by obstructions, inequalities, and roughness in the pipe or channel conveying the water. The lastnamed loss of head may be easily seen by observing the flow of water in an unlined tunnel or open ditch, with sets of timber every 3 ft. or 4 ft. Eddies and counter-currents caused by the sets of timber disturb and retard the whole sectional area of the flowing water. Experiment has demonstrated that such a tunnel or channel may be made to carry more than double the quantity of water if smoothly and uniformly lined. As in channels, so in pipes and other conduits for the conveyance of water —perfect smoothness and uniformity are of the utmost importance. A change of form in the sectional area of flowing water produces retardation. .. y "\ ■./.-. There are several methods of ascertaining the loss of head by friction (which term is taken to include all the retarding forces) in pipes of various diameters, carrying water at various velocities. A pressure-gauge may be used at any point in a line of pipes, and the difference between the readings when the water is at rest and when the water is in motion delivering a certain quantity of water (the pipes being full in both instances) is the exact measure of the loss of head that taJces place between the source and the point at which the gauge is used when the pipes are carrying that particular quantity of water. Another method quite as reliable is the calculation of the loss of head from the carrying-capacity of pipes of various diameters under various hydraulic gradients. If a pipe of any specified diameter (or H.M.D.) carries a certain quantity of water on a certain hydraulic gradient, then that gradient is the correct measure of the loss of head in that particular pipe when carrying that particular quantity of water. If a pipe 12 in, in diameter carries four sluiceheads of water on a hydraulic gradient of 1 in 100, then the loss of head in that pipe, carrying that quantity of water, will be 1 ft. of head for every 100 ft. in length of the pipe. Such being the case, any correct formula for ascertaining the carrying-capacity of pipes of various diameters under various hydraulic gradients can, by transposition, be made to give the correct loss of head from friction. The attached tabulated statement gives the results of experiments made for the purpose of ascertaining which formula in general use gives the most correct results. It will be seen that Eytelwein's general formula is not only the most correct, but by far the most simple, and it is applicable not only to pipes, but to channels also, and is in strict accordance with all the known laws of hydraulics. The formula is, "The mean velocity of water in feet per second is equal to the square root of" (twice the fall in feet per mile multiplied by the hydraulic mean depth). This formula may be stated as VRS 10560 = velocity, R being the hydraulic mean depth and S the sine of the inclination, S 10560 being equal to twice the fall in feet per mile. It must, however, be understood that the formula is correct only for long, straight, and smooth pipes or channels, but it gives the correct proportions for pipes or channels of any kind, whether crooked or straight, rough or smooth, and the results multiplied by coefficients suitable to the character of the pipe or

channel intended to be used give ultimate results quite as correct as the best and more complex methods given in works on this special subject. The attached table is founded on Eytelwein's formula; it gives the length of pipe in which 1 ft. of head is absorbed by friction in clean pipes from 6 in. to 36 in. in diameter when carrying from one to fifteen sluice-heads of water. Examples. What is the loss of head in 2,000 ft. of clean 15 in. pipes when carrying eight sluice-heads of water ? The length of pipe given in the table in which 1 ft. of head is absorbed in 15 in. pipes carrying eight sluice-heads of water being 77 ft.— ~ = 25-97 ft. loss of head. If the pipes are slightly rough add 30 per cent.— 25-97 + 25-97 x 0-3 = 7-79 33-76 ft. loss of head. If pipes are very rough, and badly laid, add 60 per cent.— 25-97 + 25-97 x 0-6 = 15-58 41-55 ft. loss of head. What is the loss of head in 1,740 ft. of clean 15 in. pipes when carrying nine sluice-heads of water ? _. 28-52 ft. loss of head. ol What is the loss of head in 1,580 ft. of rough and badly-laid 11 in. pipes when carrying nine sluice-heads of water ? = 121-53 + (121-53 x -6) = 194-44 ft. loss of head. If the quantity of water intended to be used is more than fifteen sluice-heads, take from the table the number corresponding to one-half, one-third, or one-fourth the intended quantity, and divide by 4, 9, or 16 respectively. The loss of head in a 20 in. pipe, carrying ten sluice-heads of water, is Ift. of head in every 209 ft. length of pipe (as per table). The loss of head in a- 20 in. pipe, carrying twenty sluice-heads of water, is 1 ft. of head in every &s*■ = 52-25 ft. length of pipe. The loss of head in a 20 in. pipe, carrying fifteen sluice-heads of water, is 1 ft. of head in every 93 ft. length of pipe (as per table). The loss of head in a 20 in. pipe, carrying forty-five sluice-heads of water, is 1 ft. of head in every ?£ = 10-33 ft. length of pipe. The loss of head in a 20 in. pipe, carrying sixty sluice-heads of water, is 1 ft. of head in every s 3 = 5-81 ft. length of pipe.

Hydraulic Sluicing. Capacity of Sluices. In sluices of similar character, as well as in other channels for the conveyance of water, the velocity of water is proportional to the square root of the hydraulic mean depth multiplied by the gradient. In hydraulic sluicing as carried out at Kumara (the largest hydraulic-sluicing goldfield in New Zealand) the widths of the sluice-boxes are so regulated in claims that are properly Worked that there is hut little variation in the hydraulic mean depth of the sluices in use on the field. Such being the case, in the calculation of the velocity of the water in sluices at Kumara, or other places having alluvial wash of a similar character, the hydraulic mean depth need not be taken into consideration, and the velocity of water may simply be stated as proportional to the square root of the gradient. And as the power (or force) of water is proportional to the quantity (or weight) of the water, multiplied by the square of the velocity, and as the velocity is proportional to the square root of the gradient, then it follows that the power of water is directly proportional to the quantity of water, multiplied by the gradient. This is only a modification of the well-known laws of water —the velocity of water is proportional to the square root of the hydraulic head, and the power of water is directly proportional to the quantity of water multiplied by the hydraulic head. Experiment has shown that these laws are not only applicable to hydraulic heads, but also to gradients of sluices and other open channels ; and, as the velocity of water from nozzles is proportional to the square root of the hydraulic heads, so velocity of water in sluices having uniform hydraulic mean depth is proportional to the square root of the gradients. The following rule is in accordance with the laws of hydraulics, and its correctness has been checked by experiments and measurements made at Kumara, and by the experience of most of the hydraulic miners working on that field, extending over a period of several years. The rule gives the quantity (in cubic yards) of ordinary (Kumara) alluvial wash sluiced away per hour, in ordinary sluice-boxes, paved with wood (on end) blocks, with various quantities of water, on various gradients. The rule is: The quantity of water in sluice-heads multiplied by the fall in inches per box of 12 ft. gives the number of cubic yards sluiced away per hour: — Examples. _ > Number of Fall per Quantity sluiced Sluice- Box of away heads. 12 ft. per Hour. 10 heads x 6 inches = 60 cubic yards. 8 „ x 8 „ = 64 12 „ X 7 „ = 84 14 „ x 8 „ = 112 10 „ xl 2 „ = 120 12 „ xl 4 „ = 168 The number of cubic yards per hour required to be sluiced away, divided by the fall per box, gives the quantity of water required for that purpose. The number of cubic yards per hour required to be sluiced away, divided by the number of sluice-heads of water available, gives the required fall per box. The rule will give a close approximation of the quantity of ordinary alluvial wash that will be sluiced away in sluice-boxes paved with wood blocks, provided a proper use is made of the water, and the width of the box is in proper proportion to the fall, and quantity of water. The nature of the material to be sluiced away must always be taken into consideration, as with material of high specific gravity and large quantities of spawled stone the quantity put through will be less, and with material of low specific gravity and well-rounded stones the quantity will be more. Wash is more easily sluiced when it contains a fair proportion of well-rounded stones, from 4 in. to 18 in. in diameter ; and fine heavy wash is the most difficult: the stones keep the finer and heavier material from settling firmly on the bottom of the sluice. All the blockages that occur at Kumara in the sluices there are composed of fine, heavy sand, and are seldom or never due to stones. It is necessary that the whole of the material in sluices should be constantly on the move, as otherwise blockages will occur, less material will be sluiced away, and gold will be lost. As the parties running water and tailings into the main tail-races or channels have to pay a fixed price per shift of three hours for maintenance and repairs, it became necessary to devise some means of regulating the quantity of tailings sluiced by each party into the main tail-race. As the price per shift for each party was equal, it was arranged that each party should sluice an equal number of cubic yards of tailings into the main tail-race ; and the trustees of No. 3 channel embodied in their regulations the following table for that purpose. The table was calculated so that each claim would sluice into the channel 64 cubic yards of tailings per hour, thus equalising the wear-and-tear, and giving each party equal advantage of the flush-water supplied free from the Kumara Race.

Fall to be reckoned from the total difference of level in 60 lineal feet of tail-race running free. The regulation has now been in force for some years, and has given satisfaction to all the parties interested. It will be seen that the table is calculated from the rule, " The number of cubic yards per hour required to be sluiced away, divided by the fall per box (in inches), gives the quantity of water required for that purpose." Other main tail-races have adopted the same rule. The table in the regulations for No. 4 channel is based on each party sluicing into the main tail-race 112 cubic yards of tailings per hour.

The total length of private tail-races in use at Kumara is more than seven miles, and quite double that length are now abandoned, as the ground commanded by them has been worked out. The main tail-races in use have an aggregate length of about three miles. Wear of Wood (on end) Blocks. Red-pine (rimu), being the most plentiful timber in the neighbourhood of Kumara, is the timber generally used as paving-blocks for sluices. Other timber is, however, often used, and white-pine will stand longer in sluices than red-pine, as it does not wear away so rapidly. The following rule will give the life of wood-paving blocks in sluices nearly correct, as it has been deduced from carefully-compiled information obtained from all the sluicing claims on the Kumara Goldfield. The width of the sluice (in inches) multiplied by the thickness of the blocks (in inches) multiplied by 320 gives the number of cubic yards of wash that will pass through the sluice before a set of blocks are worn out:— Examples.

water is a constant stream having a sectional area of 40 square inches, and having a mean velocity of 36 ft. per second, which will deliver 1,728 cubic inches, or one cubic foot, of water per second. The regulations under " The Mines Act, 1891," have a table showing how to construct gauge-boxes for the measurement of any number of sluice-heads of water from one to a hundred, which table is practically correct. The experiments for the calculation of the table for all gauge-boxes over two sluice-heads were made at Kumara from actual measurements of the quantities discharged through large and small openings, under various pressures. A gauge-box for delivering one sluice-head of water has an opening of 20 in. in width by 2 in. in depth (40 square inches), with a pressure-board 5 in. in depth ; and, as the total pressure is reckoned from the surface of the water to the centre of the opening, there is an actual head of water of 6 in. In such a box, constructed as described in the regulations, having an opening of 40 square inches, and a pressure of water of 6 in., the mean velocity of the water where the opening is full will be 3-6 ft. per second, and the quantity discharged will be 1 cubic foot per second, or one sluice-head. With the same opening, and a pressure of water of 24 in., the velocity would be 7-2 ft. per second, and the quantity discharged would be 2 cubic feet per second, or two sluice-heads. It takes four times the head of water to double the velocity. A sluice-head of water is a uniform and constant stream delivering 1 cubic foot of water per second. One cubic foot of water contains 6J gallons, and weighs 62J lb. A sluice-head will therefore discharge — 1 cubic foot 6J gallons, or 62Jlb. of water per second. 60 „ 375 „ 3,7501b. „ per minute. 3,600 „ 22,500 „ 225,0001b. „ per hour. 86,400 „ 540,000 „ 5,400,0001b. „ per day (24 hours). With figures such as the above before him, any person may have some idea of the effect of ten or twenty heads of water thrown against a face of alluvial wash with a velocity of from 60 ft. to 100 ft. per second, knowing at the same time that the force of the impact is proportional to the square of the velocity. 88 ft. per second equals 60 miles per hour.
NOTES ON BLASTING WITH NO. 1 DYNAMITE, BLASTING-GELATINE, AND AMMONITE, IN CHOTA NAGPUR, BENGAL, INDIA.* [Communicated by A. Mebvyn Smith.] The following notes are summarised from a carefully-kept daily register, for a period extending over two years, and give the results of actual practice with the above-mentioned high-class explosives: — The size of the shaft was 12^ft. by 6 ft.; drives, 7 ft. by 5 ft.; cross-cuts, 7 ft. by 4 ft. Country-rock medium hard blue slate (hydromica schist), easy drilled, but tough, and splitting readily along bedding-planes. Underlie 70° with the horizon. Occasional stringers of hard quartz, from 2 in. to 6 in. wide, and parallel to the bedding-planes, were met with in sinking. The reef was from 7 ft. to 10 ft. wide, consisting of a hard crystalline quartz, showing a banded structure with alternate ribbons of blue, grey, and white quartz. Highly pyritous, the iron-sulphides making up nearly 10 per cent, of the weight of ore extracted. The drilling was done by hand, the best 7 in. steel being used. It was found in practice that 2 ft. to 3 ft. holes did the most work in sinking and driving. Deeper holes did little or no work. In stoping, deeper holes were more advantageous. The drills were of four sizes—9 in., 1-J- ft., 2-J- ft., and 3J ft., the smallest size being 1-J in. wide, tapering down to 1 in. in the 3-J-ft. drills. Water tamping was used throughout, the works being wet, the water making at the rate of 5,000 gallons per shift of eight hours. Chisel-face drills, medium-blue temper, answered well for drilling in slate. Cocks-comb or crescent-face drills of the hardest temper had to be used for the quartz. 7 lb. hammers were used, and two men (natives), one striking and the other holding the bit, would drill 6 ft. in slate, or 2 ft. in quartz, in a shift of eight hours. The explosives used were No. 1 dynamite, blasting-gelatine, both supplied by Nobel's Explosive Company ; and ammonite, from the Miners' Safety Explosive Company. The cost of explosives delivered at the mine, 265 miles by rail from Calcutta, was — Per Pound. s. d.

although not as strong as gelatine, is a quicker explosive, and, therefore, more local in its effects. It breaks up the quartz near the mouth of the bore-hole, and allows the greater ballistic (throwing) power of the gelatine to take effect. In slate, gelatine alone did more work than dynamite. Ammonite was more effective in slate and in stoping than either gelatine or dynamite, but not of so much use in hard quartz or pinched holes. In holes occurring in the angles of the shaft, double the above charges were used; in the side holes, an increase of 50 per cent, on the normal charge. The centre holes were first fired, then the side holes, and finally the corner holes. Method of Blasting. In sinking shaft, 12-Jft. by 6 ft., fifteen holes were drilled. 1, 2, and 3 were first fired (not by electricity), and the debris cleared out before the second blasting, consisting of 4, 5, 6, 7, 8, 9, 10, and 11, or such of them as were left after the first blast, as it oftened happened that some of these holes were broken out by the effects of the first firing. The shaping or angle holes at 12, 13, 14, and 15 were last blasted. Progress, about lft. a day in slate, and J ft. a day in quartz. Bemarks. The above method of firing, and charges of explosives, was arrived at after numerous experiments with larger and smaller charges, with each explosive by itself and with mixtures, and with holes fired in various order. It frequently happened that unexploded cartridges of gelatine were recovered from the debris hauled out of the mine. This never happened with ammonite or dynamite. Experience proved that this was due to a little sand or clay getting in between the plugs of gelatine. In wet holes at the bottom of the shaft it was difficult to prevent dirt getting into the holes after the rammer was withdrawn to put in another cartridge. This slight packing between two cartridges deadened the detonation and prevented the explosion of the lower cartridges. Sextuple detonators (caps) were used with dynamite and gelatine. Special caps, extra strong, were supplied by the Miners' Safety Explosive Company with their ammonite, as this explosive cannot be fired with ordinary caps. A small supply of gelignite was obtained, but its use was given up, as this explosive was found to rapidly deteriorate in the hot, damp climate of Chota Nagpur. Felted fuse was used, and found to answer admirably. The following are details of cost, &c, of sinking shaft from the 50 ft. level to a depth of 150 ft.:— £ s. d.

A NEW CURRENT MOTOR. The term " current motor " is applied to a mechanism that utilises the power of the stream or current of a river in such a way that it can be applied to run machinery. A current motor, it is claimed, can be used without a dam in any location in a river where the water is deep enough to admit it. There is almost no limit, the manufacturers claim, to the use to which the power generated by a current motor can be applied. For example, it may be used for generating electricity for electric-lighting purposes; but its chief use will be in connection with irrigation and mining. The motor herewith illustrated has been experimented with and tested, and its practicability is fully believed in by its makers, the P. C. Austin Manufacturing Company, of Chicago, who claim that the only limit to its power and amount of water that can be pumped is the dimensions of the paddles, the number of them, and the force of the current. The machine, which is represented as anchored in the river, consists of a pontoon carrying two endless chains, to which are pivotally attached at suitable distances reversible paddles, having floats at their upper ends that buoy them up in their course through the water. These paddles enter and leave the water in such a way as not to detract from the efficiency of the machinery, but calculated to rather add to it. To the wheels put in motion by these cables is attached an elevator carrying large buckets, which, when entering the water to fill themselves, it is claimed, add to the generation of power, and are so arranged that when they reach the top of the elevator they discharge their contents with little friction into a trough, there to be conveyed to the shore, where a reservoir has been constructed to collect the water and distribute it through canals and lateral ditches. 23—C 3.

THE ACCUMULATION OF AMALGAM ON COPPER PLATES. [Paper read before the American Institute of Mining Engineers by R. T. Bayliss, Marysville, Montana (Pittsburgh Meeting, February, 1896).] Although every mill-man of even limited experience in the amalgamation of gold-ores is probably aware that copper plates will in time become coated by the accumulation of gold-amalgam, it may be that many do not know to what extent this accumulation occurs in the treatment of ores dissimilar to those with which they are familiar, and under conditions foreign to those with which they have to contend in any given locality. The writer, therefore, feels relieved from the necessity of offering an apology for dealing with such an elementary subject, believing that certain facts in reference thereto which have recently come under his personal observation will be interesting to many, and possibly instructive to some persons engaged in the amalgamation of gold-ores. The facts hereinafter stated were observed in the fifty-stamp " combination "-mill, owned by the Montana Mining Company (Limited), of England, operating the Drum Lummon Mine, situated at Marysville, Montana. The material treated in this mill consists of quartz and ores of somewhat variable character, containing gold and silver in native form, as well as in chemical union with the sulphides of iron and copper. There is also present a little lead, some arsenic and antimony, and a little zinc. The last four minerals, however, are of irregular occurrence, and but sparingly distributed throughout the ore, and yield only a trace in the analysis of the average material in this mill. The free gold, which is in a "condition of fine division, and rarely visible to the naked eye, carries silver as an alloy ; and the native silver, which is only occasionally observed, is present in the richer ores in wire- and in leaf-form. Of the two precious metals, the ore worked during the past three years and ten months, the period under review, contained about -J- oz. of gold, and from 7 oz. to 12 oz. of silver per ton of 2,000 lb. The ore, after being crushed in the stamp-battery and passed through a thirty-mesh steel-wire screen, runs over amalgamated copper plates, and is then concentrated on Frue vanners, to the distributor of which is affixed a small copper plate for saving any amalgam escaping from the batteryplate, the tailings from the vanners being subsequently amalgamated in pans. Amalgamation upon copper plates placed inside the mortar is not practised in this mill, better results having been obtained by amalgamation on outside or apron plates only. It is not the purpose of this paper to enter the wide field of discussion as to the relative merits of inside and outside amalgamation; but it may be observed in passing that an extended experiment upon the two methods proved that a higher percentage of saving was gained by amalgamation outside the battery than by the use of inside plates in addition to the apron-plates. The apron-plates in use in this mill are 54 in. wide and 8 ft. long, made of •§• in. rolled copper plate, electro-plated with 1 oz. of silver to the square foot. They are set with a fall of 2Jin. to the foot; are cleaned up once in twenty-four hours ; and dressed once every two, three, or four hours, as may be deemed necessary by reason of their surface-condition, which varies according to the mineral contents of the ore submitted to them. In dressing, a weak solution of cyanide of potassium is used when necessary. The copper platen upon the Frue vanners are 46 in. wide and 18 in. deep, made of in. rolled copper plate, electro-plated with 1 oz. of silver to the square foot, and are subjected to the same treatment as the apron-plates. At the daily clean-up the surface of the apron-plates is first washed ; then the amalgam which has collected during the preceding twenty-four hours is slightly softened and loosened by sprinkling a small quantity of mercury over the plate and rubbing the surface with a cloth or whisk-brush, after which the amalgam is removed with a stiff rubber scraper, 4 in. wide, made out of rubber belting. In this process the daily accumulation of amalgam is removed as completely as possible without the application of a steel scraper, the use of which is not permitted, except for the removal of blisters or any fixed impurity which may occasionally be found upon the plate. The foregoing brief summary of the method employed in this mill will be sufficient to explain the general conditions surrounding the amalgamation of the free gold contained in the ore, and the treatment to which the copper plates are exposed. To return to the special subject indicated by the title of this paper : One of the copper plates employed in this mill was recently removed, after having been in continual service for three years and ten months. During this period the battery of five stamps which it served crushed 14,942 tons of ore, yielding from amalgamation on this plate 6,426 oz. of bullion, 541-5 fine in gold, and 443-9 fine in silver, giving a standard assay-value of $11-70 per ounce, and showing the recovery of $5-03 per ton of ore crushed. In fixing the total tonnage of ore passed over this plate, and the yield in bullion therefrom, the total tonnage and production of the mill during this period has been divided by ten. As all the stamps have been operated continuously, this proportion should correctly represent the duty performed by the particular plate under consideration. The agreeable task of removing the amalgam known to have accumulated upon this plate (which was new when put in) was then undertaken, and the accumulation or scale was removed by striking the back and front of the plate with a light hammer, a small block of wood being used to deaden and distribute the blow. By this means the plate is slightly buckled, causing the amalgam to scale off, and leaving upon the original electro-plated surface but an insignificant film or layer, which is subsequently removed with a chisel or scraper. Other methods, such as sweating with hot water and immersing the plates in chemical solutions, have been tried, but have proved unsatisfactory ; and the process of buckling the plate, although a somewhat drastic and unscientific method, has been found to effect the recovery of the highest percentage of the accumulated amalgam, xlfter this treatment, the plate is usually so damaged as to be unfit for further service; but, notwithstanding that every visible portion of
173
C—3
amalgam has been removed, the copper plate is still found to carry a considerable quantity of gold and mercury, and upon being cut up and melted into a bar the value of the gold- arid coppercontents amounts to more than twice the value of a new plate ; hence the substitution of new plates for old is an expenditure which can be viewed without concern. The results obtained from the foregoing treatment of the particular copper plate here specified were both interesting and of substantial value, the scale or accumulation of amalgam at the head of the plate being no less than 0-16 in. in thickness, and gradually decreasing to a bare fj in. at the lower end. The total weight of the amalgam so recovered was 160 lb. avoirdupois, which, upon being retorted, yielded 60-5 lb., or 38 per cent., of crude bullion, and produced after melting a gold bar weighing 866-1 oz. troy, which, upon assay, proved to have a total fineness of 993 9, being 431-4 fine in gold and 562-5 fine in silver, and having a standard value of $963 per ounce; thus making the total value of bullion recovered from the accumulated amalgam upon this one plate no less than $8,340-54. It may be remarked that the results recorded in this instance are not by any means exceptional. Other plates in this mill placed in service at the same time as the one forming the subject of this paper appear to be coated with an accumulation of amalgam of equal weight and value; and, moreover, within the writer's experience of other plates removed from this mill in past years is an instance in which one plate yielded accumulated amalgam in excess of $11,000. An examination of the facts observed in the course of cleaning this plate, and converting the amalgam into bullion, reveals one or two interesting features which appear to be worthy of record. As stated above, the percentage of bullion in the amalgam obtained was 38 per cent., whereas the amalgam from the daily clean-up never contains more than 20 per cent, of bullion, and frequently not more than 10 per cent. This is, no doubt, due to the circumstance that the amalgam remaining upon the surface of the plate is subjected to greater compression than that which is cleaned off, and merely strained through canvas sacks. The accumulated amalgam obtained from the plate in the shape of scale does not appear to suffer any visible alteration in form or size during the process of retorting. A piece -J- in. thick and 1 in. square will pass through the ordeal of retorting, and emerge as crude bullion, having preserved, without apparent loss, its original dimensions, and still retaining on its surface any ripple-marks or imperfections which it bore during its existence as amalgam. A comparison of the fineness of bullion obtained from the accumulation of amalgam upon this plate with the average fineness of bullion produced from the daily clean-up of the plate, during its service of three years and ten months, of which one would suppose the accumulated amalgam to be a fair sample, shows that, to a striking degree, this is not the case. The average fineness of bullion obtained from daily clean-ups during the period mentioned was Au, 541-5; Ag, 443-9 —total, 985-4 : whereas the fineness of bullion obtained from the accumulation upon this plate during the same period was Au, 431-4 ; Ag. 562-s—total, 993-9 : from which it will be observed that, although the total fineness of the latter—993-9—is greater than the fineness of the former —985-4 —the gold fineness is 110-1 less and the silver fineness 118-6 more. That the total fineness of bullion from the accumulated amalgam should be higher than that obtained from the daily clean-ups is not a matter for surprise, since the amalgam gathered from the plates from day to day would naturally contain a higher percentage of impurity and base metal than the amalgam which adhered to the surface of the plate ; but it does not clearly appear why the gold fineness of the latter should be so much lower than that of the former, the difference being represented by a corresponding increase in the silver fineness. In explanation of this inconsistent feature, it has been suggested that the native silver contained in the ore has a greater tendency to accumulate upon the plates than the free gold, owing to its stronger affinity with the amalgamated surface. If theory furnishes any authority for such a statement it is rudely disproved by actual experience in this particular instance ; for test-samples of the accumulated amalgam from the head and tail of this plate prove the former to be 0-020 finer in gold than the latter, with a corresponding increase in the silver fineness of the amalgam from the lower end of the plate. Furthermore, the amalgam saved upon the copper plates forming the distributor of the Frue vanners invariably shows, upon assay, a lower gold and a higher silver fineness than the bullion recovered from the treatment of the same ore upon the battery-plate; a sample of this vanner amalgam yielding bullion assaying—Au, 380-5 ; Ag, 602-0 : total, 982-5. In other words, the silver, instead of showing a strong affinity with the amalgamated surface, gives evidence of a persistent tendency to escape amalgamation, as proved by the foregoing assays, which show that the gold fineness of bullion is highest nearest to the battery, and gives place to a steadily-increasing silver fineness as the amalgam is deposited upon the copper plates at greater distance from the batterydischarge. The natural conclusion to be drawn from these facts and figures would justify the expectation that the bullion derived from the accumulation of amalgam on copper plates would be of equal (if not of higher) gold fineness to that recovered from the daily clean-ups upon the plates during the period in which the accumulation was in progress. The foregoing facts, however, incontestably prove that such is not the case ; and the purpose of this paper will be served if the facts herein presented, which have been prepared with due regard to accuracy, are the means of suggesting an explanation of this interesting inconsistency, which the writer most frankly confesses himself unable to supply.

CLASSIFYING TAILINGS BEFORE CONCENTRATION. Messrs. W. Bettel and J. H. Johns have been carrying on at the Perreira Mill some novel experiments on behalf of the Chamber of Mines, Johannesburg. It was believed that better results could be got by classifying the pulp previous to concentration; but the anticipations were not realised. The experiments were in the direction of roughly classifying by means of spitzluten and spitzkasten, and of passing that pulp alone which came from the spitzluten over the vanners. It was found that under these conditions the vanners have not caught their usual percentage of metal. The explanation offered may be thus summarised : (1.) Overloading. (2.) To a principle which has hitherto not been recognised on these fields, but is well known on the diamond-fields— that minute particles of high specific gravity will subside through a shallower layer of pulp suspended by agitation in a turbid medium (such as a mixture of coarse and fine sand, pyrites, and clay) more readily than through a classified pulp, consisting of coarse particles suspended in clear water. This may be explained by assuming a reduction of surface tension in the former case. (3.) The proportion of fine gold escaping in sands and slimes is increased when an excess of water (over normal) is present in the pulp. (4.) With spitzluten, an increased clear-water supply carries off fine gold and floured amalgam in considerable amounts in slime-pulp. (5.) The scouring action of the coarse sands, &c, from the spitzluten (free from slimes) prevents the collection of floured amalgam on the shaking amalgamated plates on the vanners, and this amalgam so lost is not wholly recovered in the concentrates collected. The pulp (consisting of slime and finest sands) delivered by the spitzkasten is imperfectly concentrated on the third vanner, such pulp requiring a large area equal to a very shallow layer of liquid for efficient concentration. The finest slimes (solid matter in effluent from spitzkasten) are very rich in gold. This is attributed to the presence of suspended floured amalgam and free gold of extreme tenuity, probably coated with films of grease or sulphides, which cause the particles to exert an increased surface tension sufficient to overcome the action of gravity to a very considerable extent. The results obtained are, however, extremely interesting, and may, under other circumstances, have a distinct commercial value. When Frue vanners are used for concentration, previous classification, in the opinion of the experimenters, would not be advantageous, but where any other concentrator, not having a vanning motion, is employed they would recommend a previous classification of the battery-pulp.
GOLD-EXTRACTION FROM REFRACTORY ORES. Mr. Hiram S. Maxim is the patentee of an improved process of extracting gold from refractory ores. He takes the advantage of the affinity existing between gold and lead when both are at a high temperature, and subjects the ore to the action of molten lead in the presence of a reducing gas or atmosphere. Whilst in the presence of a reducing gas or atmosphere the ore and molten lead are pounded, and the mass is slowly rotated or stirred. The apparatus comprises a strong rotary retort of cast iron or mild steel located in an inclined position within a furnace, and provided with a cylindrical extension, which extends through the backwall of the furnace, and is carried in bearings supported in strong pedestrals. The end of the extension is furnished with a toothed wheel, which gears with a pinion mounted on a driving-shaft revolved from any motor. In order to counterbalance the weight of the retort and its charge the cylindrical extension may be formed with a considerable mass of metal near its outer end. The mouth of the retort is provided with a cover. The earths to be acted upon are placed in the retort in a pulverised condition together with the lead. A number of loose balls of iron may be placed within the retort, together with the earths and lead. The inner surface of the retort is provided with longitudinal ribs, so that when the retort is revolved the balls will be raised by the ribs, and allowed to fall again to the mass at the bottom of the retort, thereby grinding the earth to a still finer condition and at the same time causing the molten lead to come into very intimate contact with the gold contained in the earths. During the process a current of carburretted hydrogen, such as coal-gas, or, still better, petroleum vapour, is allowed to pass into the retort through a pipe, the said gas or vapour expelling the atmospheric oxygen and also taking up any oxygen that may be set free. As the retort slowly revolves the molten lead, under the action of the heat and the pounding of the balls, is finely divided and distributed throughout the mass within the retort without becoming oxidized, and is therefore constantly brought into intimate contact with the gold contained in the earths. The process may be continued until all or nearly all of the gold has been taken up by the lead. The rotation of the retort is then arrested, the heat diminished, and the contents of the retort are discharged into water. The lead is then separated from the lighter earths by suitable means, and is then subjected to a high temperature in a furnace and in the presence of atmospheric oxygen until it becomes wholly oxidized, when a " button " containing the gold will be found in the cupel of the furnace. By this process the molten lead is always preserved in a bright metallic condition, the presence of the carburretted hydrogen completely preventing the oxidation of the surface of the lead and keeping it untarnished at a high temperature. In some cases finely-divided animal and vegetable charcoal or other carbonaceous materials may be mixed with the earths before or during their treatment with the molten lead. The cylinder may be placed at an inclination with one end partially open, and then revolved, a hot reducing flame of gas being directed into the open end of the cylinder. The contents of the cylinder will thus be heated to a higher temperature than the cylinder itself, and in the presence of a reducing flame.

CONCERNING TELLURIDES. From the Mining Journal, Railway and Commercial Gazette."} The announcement that telluride ores have lately been discovered in depth in some of the West Australian mines has attracted a considerable amount of public attention, and whilst this fact, for such it appears to be, has been made use of for the purpose of, as far as possible, "booming" the properties upon which the finds have been made, the public have not as yet shown any symptoms of desperate eagerness to rush in and buy up the shares of these vaunted telluride properties. Possibly the public have come to the conclusion that what they want is gold, that a goldfield which at the end of ten years' hard work only produces 281,000 oz. can hardly make up any deficiencies with tellurium. We remember not more than a dozen or so years ago that the chairman of a goldmining company gravely informed his shareholders that unfortunately the assay-value in gold of the ore had been very much lower than was anticipated ; but, on the other hand, analysis showed their ores to contain a considerable percentage of aluminium, the presence of which would doubtlessly recoup them for the low yield of gold. The investing and even the speculating public is getting wiser nowadays, and we look upon the general desire to know what tellurides are as a hopeful sign. It is the best thing possible when shareholders in mines begin to take a real interest in the more technical portions of their subject. We hold this view so strongly that we propose to explain to-day what tellurides are, how they are worked, and where they occur, for the benefit of our unscientific and non-technical readers, and we shall ask our mining friends to excuse this statement of facts familiar to them, though, after all, they are not compelled to read this particular column, unless they perchance wish to refresh their memories. Tellurides, then, or telluride ore, is the general term applied by miners to a series of minerals into the composition of which the rare element tellurium enters in considerable proportion. Tellurium itself presents many analogies to sulphur, and forms with many of the metals compounds known as tellurides, strictly analogous to the sulphides. There is, however, this curious fact about tellurium : that it is the only known mineraliser of gold—that is to say, that native compounds or gold and tellurium exist although gold is not found in nature combined with any other element. We are quite aware that certain authorities consider that gold occurs in combination with sulphur, but the evidence in favour of the existence of such a compound is far from clear, and upon the whole it seems more probable that there is not a native sulphide of gold than that there is. In the matter of the telluride there is, however, no doubt possible. We have, for instance, the mineral sylvanite, also known as graphic or graphic tellurium, a tin-white to steel-grey brittle mineral, consisting of gold and tellurium only in its purest form, though it contains at times small or large quantities of silver and lead. The other important telluride minerals are : Calaverite, a yellowish-grey brittle telluride of gold; nagyagite, a soft blackish-grey mineral, consisting chiefly of tellurium, lead, and gold, and some sulphur; hessite, a telluride of silver, with some gold; petzite, a telluride of silver, with much gold ; there are besides other tellurides, such as altaite, a telluride of lead; tetradymite, joseite, and wehrlite, tellurides of bismuth ; and a few other minerals of less importance, such as melonite and krennerite. Whatever their composition, all this list of tellurium minerals is especially characterized by its persistent occurrence in connection with gold, and in goldbearing veins. Not only do a large number of the above tellurides contain gold as an essential constituent, but nearly or quite all of them at times contain gold as an accidental constituent, so that any of them on assay would show more or less of the precious metal; but, besides this, they are almost invariably accompanied by free gold. In veins containing tellurides those portions that show the largest amount of these minerals are almost invariably the richest in free gold, and specimens are known of such minerals as altaite, themselves almost free from combined gold, showing well-marked plates of native gold that have been deposited between the cleavage planes of the tellurium mineral. The intimate association between tellurium and gold is too marked and obvious to be overlooked, though it would be very difficult to assign its precise genetic meaning to this phenomenon, although no one doubts that it has a very important significance if we could only interpret it aright. As far as we know, tellurides never occur in any quantity except in this intimate connection with gold; but it by no means follows that gold always occurs in association with tellurides, certain important gold-producing districts being quite free from these minerals. In Europe tellurides are chiefly known in the very important gold-mining districts of Transylvania, at Offenbanya, and Nagyag in Siebenbiirgen, Schemnitz in Hungary, &c, in various localities in the Altai, and in small quantities at the Bremna3s Mine in Norway. As far as we know, tellurides do not occur in the Mysore goldfields, and their only known Asiatic occurrence so far is in the Choukpazat Goldmines in Upper Burmah. We have no record of the occurrence of tellurides in Africa; they have not, we believe, been identified even in small quantity in the Witwatersrand conglomerates, in spite of the large number of minerals that have now been determined in these beds. In America tellurides are widely disseminated; they occur in numerous localities along the great Mother lode of California, especially on the Stanislaus and in Calaveras County ; they have been found in numerous localities along the eastern gold belt, notably in Virginia and North Carolina; also, but more rarely, in Montana; and quite recently in the now well-known Cripple Creek district of Colorado. In South America tellurides are known in Brazil. We believe that tellurides have not hitherto been found in Australasia, the recent discoveries in Western Australia being the first, and serving still more to sharply differentiate the gold occurrences of Western Australia from those of the rest of that continent. It will thus be seen that the occurrence of tellurides in gold-mines is decidedly capricious; it occurs in some very rich districts and in some decidedly poor ones, whilst some of the most productive gold regions have never produced any tellurides at all. Upon the whole, it seems as though tellurium, whilst distinctly characteristic of gold districts, is apt to be found associated with low-grade rather than with high-grade ores, This is certainly the case

with the greater majority by far of the districts in which tellurides are particularly known to occur. The treatment of tellurides for the extraction of gold depends very much upon the proportion of these substances, and upon that of the free gold associated with them. Rich tellurides are being treated at Schemnitz, in Hungary, by means of sulphuric acid, which dissolves the tellurium, this substance being afterwards reprecipitated and collected ; the gold is obtained from the residues by smelting. As tellurium has, however, no special use in the arts, and is, in fact, only a chemical curiosity, it is not in the least likely that such an expensive process will find any extended application, and the tellurium in most gold-ores can only be regarded as an objectionable impurity to be got rid of as promptly as possible. The presence of tellurides appears in no wise to interfere with the amalgamation of any associated free gold; it is well known that the extraction by amalgamation of the gold-ores of the Californian Mother lode is exceedingly high, as good practice is being made there as in any part of the world, in spite of the presence of tellurides in most, if not all, of these ores. Of course, this statement applies to the free gold only ; any gold in combination with tellurium is not affected by mercury, and cannot, therefore, be saved by amalgamation. The combined gold will, therefore, have to be caught by concentrating machinery, and in all the districts in which tellurides are abundant tellurium can be found in the concentrates. Unfortunately, however, most of these tellurides are very brittle minerals, and the action of the stamp-mill crushes them to the finest possible powder. Unless special precautions are taken a large proportion of these valuable tellurides is apt to be ground to an impalpable powder and lost in the slimes. Telluride ores need, therefore, the best and most accurate vanner arrangements ; the mill screens should.be as coarse as possible compatible with a complete amalgamation of the free gold; and the depth of discharge should similarly be kept as low as possible; the issuing pulp should be sized, and even the finer grades sent to separate vanners, so as to collect these valuable concentrates as completely as possible. All these precautions are well worth taking, because in many telluride ores a great portion of the value is locked up in the tellurides. Once obtained as concentrates there is no special difficulty in treating telluride ores. We do not know that it has yet been definitely proved whether the cyanide process is or is not capable of decomposing a telluride of gold, and of extracting the gold from it. We are inclined to think that such a reaction would not take place, and that telluride concentrates ought to be roasted before being cyanided. If this view is correct chlorination would probably prove preferable to the cyanide method of treatment, for in chlorination it is always necessary to roast the ore first. There is no special difficulty in roasting tellurides, which are completely decomposed in the calcining furnace. According to some authorities there are heavy losses of gold in calcining telluride ores, as much as 20 per cent, of the gold being thus lost according to one writer. That any such loss occurs in practice appears upon the whole quite unlikely, and it even seems questionable whether there is any abnormal loss at all in an ordinary chloridizing roast, seeing that chlorination has been most particularly successful in those two districts of the United States where telluride ores more especially occur—namely, on the Mother lode of California and on the gold belt of the south-eastern States. At any rate, it is in the highest degree improbable that any serious loss can occur if roasting is carefully conducted in a modern " Fortschaufelungsofen" (the multiple-bedded long calciners), especially if fitted with dustchambers. As this calcination will remove the tellurium, the roasted product can of course be treated in identically the same way, whether tellurium be present or not, in the original ore. Telluride concentrates can also be treated by smelting. It is said that there is some liability to volatilisation in the smelter; and this may be true, but the difficulty can probably be overcome by suitable arrangements. To sum up the subject in a few words, the presence of tellurides in the ores of a given gold district prove nothing as to the richness or poverty of the district, although tellurides generally characterize low-grade ores; they show that the permanent water-level has been reached, and render it probable that the character of the ore will continue from that point downwards without much change. Their treatment presents no difficulty that an experienced mill-man should not be capable of overcoming successfully.
CYANIDE PATENT. Analyst, Mines Department, to Under-Secretary for Mines. Sir,— Wellington, 17th November, 1896. As you perhaps will be aware, I have discovered that free cyanogen does not attack gold. Consequently, as Mr. Button, M.H.R., was the first to point out to me and others, the cyanide patent appears to be invalid. Now, this is a discovery the merit of which, though belonging to me, may go a different way, and it is to place certain evidence on record that I state this evidence now. It so happens that Professor Black also found out that if cyanogen attacks gold it is very slowly, and it had possibly to be partially decomposed first. It also happened that he was examined before me in the cyanide case before the Registrar of Patents, and then gave evidence of the nature I have stated. But this scientist was set on at this investigation by Sir Robert Stout, who himself was instigated, I believe, to this by a question asked of Mr. Greenaway (the Cyanide Company's agent), which question was, " Do you think that cyanogen itself would be of any practical use in the cyanide process? " I say " believe," because there is no absolute proof of this question instigating
177
0.—3
Sir Robert Stout, as I affirm; but it certainly appears that my affirmation is correct—viz., that the question put did instigate him as I say. Now, Sir, J suggested the question to our lawyer, Mr. Button, telling him that I had good reasons for believing that cyanogen in water would not dissolve either gold or silver, and Mr. Button admits this, and has been kind enough to write me a letter stating the fact. He also says no one else suggested the question to him, or ventilated the subject in any way to him. Further, Mr. Button, anxious that I should have any credit there is due to me in the matter, asked Professor Black if this suggestion had not put him on to the investigation in question. Professor Black only gave the answer that "he did not know," when Sir Robert spoke to say that he (Professor Black) was told to do the experiments a week before. So, any way, here is some evidence that Professor Black did start on the work to some one's suggestion or wish. This evidence is on record for legal purposes, but it may not, as there, be of the use it should be to me. I feel certain that it was my suggestion that started Professor Black to his investigations in this matter. The best chemists in England and Germany never doubted but that this gas would dissolve gold, else they probably would have torn the cyanide patent up years ago, or, any way, have made it hard for the cyanide monopolists to maintain their patents. Sir, I have evidence twenty years old to show I was then so informed by investigations of my own as to be in that position which would enable me —nay, force me —to doubt the power of cyanogen to dissolve gold ; and, as this evidence was only in the Transactions of the Philosophical Society here, I was practically about the only man, in this world at least, who could have doubted in this matter. These researches of mine led up to this doubt, but it was only when Sir Robert pressed cyanogen to the fore in his defence that it occurred to me to test the question. In conclusion, I may inform you that I have papers read to the Philosophical Society here -—26th August and 23rd September for this year —stating that cyanogen does not dissolve either gold or silver. Ido not think the matter requires further investigation than I have made to establish the assertions I make. If cyanogen is really the only substance patented, the cyanide patent is, I think, completely broken up both here, in England, and Australia. I have, &c, The Under-Secretary, Mines Department. William Skey.
PATENT RIGHTS GRANTED. Improvement in the Cyanide Process op extracting Gold. We, Edward Holland, engineer, and George William Horn, mine-manager, both of Kuaotunu, Auckland, New Zealand, do hereby declare the nature of our invention for "Improvement in the Cyanide Process of extracting Gold," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — The object of our invention is to extract the precious metals from crushed and reduced ores and from slimes with greater facility and with a reduced consumption of cyanide. In carrying out our invention we make use of the ordinary vats filled with cyanide and water, which is allowed to soak into the ore in the usual manner. At the bottom of the said vats are placed battens 2 in. in depth, laid on the bottom of the vat at a sufficient distance apart to support laths, which are nailed to them at equal distances apart, the whole forming what is called the " filter-bed." Above the said laths, and over the filter-bed, is placed a stout piece of cloth covering the whole surface, and grouted around its edges, forming what is called the " filter-cloth." By our invention we then pass a pipe preferably through the centre of the bottom of the vat, and lead it into a chamber placed also in the centre and above the filter-cloth, which chamber is fitted with a series of air-pipes projecting out horizontally. In these air-pipes are formed small exit-holes which are so constructed as to allow the air to impinge upon the filter-cloth at about an angle of 20° to the horizon, thus forcing the air upon the filter-cloth, and greatly assisting the percolation through the said cloth. We prefer to draw the supply of compressed air from a compressed-air accumulator supplied with compressed air by any suitable means, such as an ordinary air-pump, the accumulator allowing the air to pass into the vat smoothly and regularly at any required pressure. The air, after impinging on the before-mentioned cloth, passes upwards through the solution of cyanide and ore, causing the cyanide to act with greater energy on the precious metal contained in the ore, thus reducing the time required for the extraction of the precious metal, and in most cases reducing the consumption of cyanide, and thus minimising the cost of the treatment; moreover, in treating fine slimes the force of the air percolating through the fine material causes the solution to come more freely in contact with the precious metal, thus facilitating its extraction. We wish it to be understood that our invention admits of its many variations in the details of carrying it into effect. Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be performed, we declare that what we claim is: In the extraction of precious metals by the use of cyanides and the like, the introduction of compressed air as and for the purposes substantially as described herein. Dated this Ist day of June, 1896. Henry Hughes, F.A.1.P.A., Agent for the Applicants.

Improvements in the Recovery of Gold and. Silver prom their Solutions. We, Carl Wilhelm Heinrich Gopner, of Canalstrasse, 46, 48, Uhlenhorst, Hamburg, Germany, chemical manufacturer, and Heinrich Ludwig Diehl, of Xl Grassbrook Vogelreth, 8, Hamburg, Germany, chemist, do hereby declare the nature of our invention for " Improvements in the Recovery of Gold and Silver from their Solutions," and in what manner the same is to be used and performed, to be particularly described and ascertained in and by the following statement : — The leaching of auriferous ores or tailings by solutions of potassium-cyanide gives solutions containing free alkali, the gold in solution as potassium-aurocyanide, or sometimes as potassiumauricyanide, and a large excess of potassium-cyanide. When silver is present in the ores or tailings it is also found in the solution as a cyanide. This invention relates to the treatment of such solutions in such a manner as to effect precipitation of the gold and silver cyanides and regeneration of the leaching material. For this purpose the solution resulting from the leaching has added to it cupreous cyanide, which is acted on by the potassium-cyanide, forming soluble cupreous potassic-cyanide. There is then added an acid, such as sulphuric acid, capable of decomposing potassium-cyanide, whereupon the ingredients of the solution are decomposed, forming hydrocyanic acid and potassium-sulphate, which remain in solution while auro- or auri-cyanide and cupreous cyanide are precipitated, as well as silver cyanide when there is silver in the solution treated. In the practice of the process it is of advantage to add the cupreous cyanide in excess, so as to render the precipitation of the gold as complete as possible, the precipitate consisting then of auro-cupreous cyanide and cupreous cyanide. The solution, decanted or otherwise separated from the precipitate, is slightly supersaturated with caustic potassa, so as to produce fresh potassium-cyanide, which can be used for again leaching. In order to obtain gold in the precipitate in sufficient amount to render it suitable for treatment to recover the gold the precipitate from the first operation is dissolved, wholly or partially, in a fresh quantity of the solution obtained by the leaching, and fresh cupreous cyanide is added, if necessary, and then acid to effect a fresh precipitation, and this may be repeated a number of times until sufficient gold is accumulated. When cupreous cyanide is added in considerable quantities in the first operation a number of successive precipitations may be effected without further additions of cupreous cyanide. The process described is applicable where the solution obtained by leaching already contains copper, but in such case the quantity of cupreous cyanide added may be less than when no copper is present. When silver as well as gold is present in the solution obtained from the leaching the process may be modified as follows : A soluble salt of silver, such as the nitrate or sulphate, is added to the solution, but not in such quantity as to effect precipitation ; or a silver salt insoluble in water, such as the cyanide or the chloride, may be added, but the quantity should be such that very little of it remains undissolved in the solution. Acid is then added, and thus the silver as well as the gold is precipitated as a cyanide. The quality of silver salt added should be such that the silver in it, together with that in the solution treated, should be considerably in excess of the gold. In the leaching and precipitation processes sodium-cyanide may be used instead of potassiumcyanide, this being regenerated by adding soda instead of potassa to the solution separated from the precipitate. Also mixtures of sodium and potassium cyanides may be used for leaching, and may be regenerated from the separated solution. Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be performed, we declare that what we claim is,— 1. The herein-described process for precipitating gold and silver from their cyanide solutions by adding to these cupreous cyanide and then an acid. 2. The repetition of the process on the precipitate with fresh quantities of solution, so as to accumulate gold in the precipitate. 3. The regeneration of the leaching solution by adding caustic alkali to the solution separated from the precipitate. 4. In applying the process to solutions containing silver as well as gold, the use of a silver salt for effecting the precipitation. Dated this 10th day of September, 1896. C. Gopner. L. Diehl.
An Improved Process for the Extraction of Gold and Silver from their Ores. I, Kate Alberta May, of 42, Blyth Road, London, England, gentlewoman, do hereby declare the nature of my invention for "An Improved Process for the Extraction of Gold and Silver from their Ores," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — My invention relates to an improved process for the extraction of gold and silver from their ores, and has for its object the removal from the crushed ore by treatment before amalgamation of deleterious compounds, such as sulphides of iron, or arsenical, antimonial, and cupric compounds which occur in some gold- or silver-ores. To carry my process into effect the ore is first crushed in any usual manner, and the crushed ore may be treated by leaching with a solution of mixed alkaline hydrate and carbonate, either cold in the case of weakly pyritic ores, or hot in other cases, but preferably in most cases the ore is boiled for about one hour in a solution containing about 5 per cent, of an alkaline hydrate such as caustic soda, and 5 per cent, of an alkaline carbonate such as carbonate of soda. The boiling solution may be agitated with or percolated through the ore, and after one hour's boiling is allowed to stand for at least twenty-four hours.
179
G.—3
In the case of arsenical copper or antimonial ores the solution is poured off or drained away from the ore, which is then leached with water to remove any excess of the chemical solution remaining therein. One washing is usually sufficient. These ores are then ready for treatment by amalgamation with quicksilver to collect the precious metals in any usual manner on plates, in barrels, or pans. It will be found that the dissolution of the arsenical, cupric, and antimonial compounds by my aforesaid preliminary treatment much enhances the ease and efficiency of the usual treatment by amalgamation, preventing the flouring or sickening of the mercury employed in the said amalgamation, and giving increased extraction. In the case of the ordinary ores, or ores containing chiefly iron-pyrites and without arsenical or antimonial compounds, my solution decomposes the sulphides of iron, and such ores, after treatment with my solution, and standing as aforesaid, may be passed at once to the amalgamating-pans, barrels, or plates without draining off the solution or washing unless it is desired and practicable to again use the solution. The total amount of my solution used in each case will vary according to the refractory or rebellious character of the ores, but may always be used in excess, in which case the partiallyexhausted solution can be refortified and used again. In the absence of carbonate of soda, soda crystals (common washing-soda) may be. used in my solution with equal effect, care being taken that the necessary amount of carbonate of soda be present. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. A preliminary treatment before amalgamation of gold- or silver-ores with a mixed solution of alkaline hydrates and alkaline carbonates. 2. A treatment of gold- or silver-ores before amalgamation, consisting of the boiling of the crushed ore for at least one hour in a solution of mixed alkaline hydrate and carbonate, such as caustic soda and carbonate of soda, and the after-digesting of the ore for at least twenty-four hours in said solution, substantially as described. 3. The washing and draining-off of the solution from the ore sludge of arsenical, cupric, or antimonial ores after boiling and digesting before passing same to amalgamation, substantially as described. 4. The composition of the solution for a preliminary treatment of gold- and silver-ores, consisting of equal parts by weight of alkaline hydrate and carbonate, such as 5 per cent, of caustic soda and 5 per cent, of carbonate of soda, with 90 per cent, of water, substantially as described. Dated this 14th day of October, 1896. Kate Alberta May.
An Improved Machine for Use in the Extraction of Gold from Auriferous Material by the Aid of Chemical Solvents. I, Joel James Deeble, of Rae Street, Bendigo, in the Colony of Victoria, metallurgist, do hereby declare the nature of my invention for " An Improved Machine for Use in the Extraction of Gold from Auriferous Material by the Aid of Chemical Solvents," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — This invention has been devised in order to provide a machine for use in the extraction of gold from auriferous material by the aid of chemical solvents, in order to insure the particles of auriferous material being brought into intimate contact with the cyanide or other solvent solution. It consists of a vat or pan to receive the auriferous material to be treated having at or about its centre a vertical shaft or spindle with one or more agitators or stirrers attached to its lower end. Motion is imparted to this shaft or spindle by bevel gearing or other convenient mechanical contrivances, and means are provided for reversing the rotation and controlling the speed of the agitators, as well as for raising or lowering the agitator shaft or spindle. These means may consist of a screw-threaded lifting-rod fitted with a correspondingly threaded bevel wheel, in gear with a bevel pinion fitted with a crank-handle, whereby it may be rotated in the required direction, or, if preferred, a rack and pinion may be used for the purpose. The inner side of the wall of this vat or pan is provided with a series of projections which produce eddies or swirls in the material under treatment as it is carried round the vat or pan. In order to drain or draw off the gold-bearing solvent from said vat it is provided with a vertically-sliding valve, or, if preferred, a pipe or pipes might be used for this purpose. A waste discharge-valve may also be provided in the lower part of the vat or pan for the purpose of enabling the waste material to be sluiced therefrom after the gold has been dissolved and the goldbearing solution has been drawn off through the valve above referred to. The accompanying drawings will more clearly illustrate the construction and arrangement of my improved machine : Figure 1 represents a vertical central section of said machine; Figure la, a plan of part of the driving-gear; Figure 2, a side elevation of said machine; Figure 3, a sectional elevation; and .Figure 4, a plan of a vat drawn to a smaller scale ; Figure sis a side elevation of the vertically-sliding valve above referred to; Figure 6is a plan thereof ; Figure 7is a horizontal section on line 7-7, Figure 5 ; Figure 8 is a vertical central section on line 8-8, Figure 5 ; and Figure 9 is a side elevation of said valve. The same letters of reference indicate the same or corresponding parts in all the figures. A represents a vat to contain the auriferous material to be treated, while B represents the vertical spindle which is provided in or about the centre of said vat, and which carries the agitators or stirrers C on its lower end. These latter consist by preference of projecting bars or arms, as shown, and they may be attached at their inner ends to a casting c 1 on the lower end of the spindle B, which is preferably made square, or otherwise sided in cross-section, and is passed 24—C. 3.

through a corresponding hole in a bevel wheel D, which is supported in a casting d resting upon bearers or beams d 1 extending across from side to side of"the vat A. This construction'admits of rotary motion being imparted to said spindle B, and-yet allows of its being raised or lowered as required. For this latter purpose a screw-threaded rod Eis connected to the end of said spindle by a shackle _, and is fitted with a corresponding threaded pinion e l , in gear with a second pinion e 2 having a crank-handle e s . Steps / are provided leading up to a platform F in a convenient position over the centre of the vat, to enable the crankhandle c" to be operated. Rotary motion is imparted to the stirrers by the bevel gearing g, g, and a clutch g 1 (see Figure la) to connect or disconnect said gearing as required. H, H represent the projections which are provided upon the inside of the wall of the vat A for the purpose of imparting a series of eddies or swirls to the material in the vat, so as to more thoroughly bring the whole of such material in contact with the solvent solution. These projections may be made integral with said vat, or may be attached thereto. As will be readily understood, I represents the vertically-sliding valve which is used for drawing off the solvent solution from the vat A. It is arranged to be slid up and down in a frame i by means of a screw-threaded rod i l , so that it can be opened more or less according to requirements. J, Figure 2, represents a waste dischargevalve which is fitted in the lower part of the vat, and enables the debris therein to be discharged after it has been treated and the gold-bearing solution has been drawn off. If preferred, a series of discharge-pipes might be used for this purpose instead of the valve, stoppers or plugs being withdrawn from said pipes as required. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The combination and arrangement of parts constituting the herein-described machine for use in the extraction of gold from auriferous material by the aid of chemical solvents, the whole being constructed and arranged substantially as and for the purposes specified, and as illustrated in the accompanying drawings. 2. In a machine for use in the extraction of gold from auriferous material by the aid of chemical solvents, agitators or stirrers projecting from a shaft or spindle (such as B), capable of being adjusted vertically, and being rotated by suitable gearing, substantially as and for the purposes specified, and as illustrated in the accompanying drawings. 3. In a machine for use in the extraction of gold from auriferous material by the aid of chemical solvents, a vat having projections (such as H) around the inner side of its walls, substantially as and for the purposes specified, and as illustrated in the accompanying drawings. 4. In a machine for use in the extraction of gold from auriferous material by the aid of chemical solvents, a valve (such as I), together with means whereby it may be adjusted vertically in the side of the vat, substantially as and for the purpose specified, and as illustrated in the accompanying drawings. Dated this 21st day of May, 1896. Joel James Deeble.
An Improved Regenerative Process for the Treatment of Argentiferous Sulphide Ores. I, Ernest Frederick Turner, of the Adelaide University, in the Province of South Australia, analytical chemist, do hereby declare the nature of my invention for "An Improved Regenerative Process for the Treatment of Argentiferous Sulphide Ores," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — My invention relates to the treatment of argentiferous sulphide ores, and more particularly zinciferous sulphide ores, galena, and argentiferous galena, containing gold and other metals. It has for its object the extraction of the several metallic contents, together with the utilisation of certain products of the process for the regeneration of the materials employed therein, and for the obtaining of certain by-products of commercial value. In my invention the raw sulphide ore is disintegrated by the action of hydrochloric acid (HCI), resulting in the formation of metallic chlorides, which are subsequently fused and the metals recovered, and in the production of sulphuretted hydrogen (H 2 S), which is used as fuel, and the products of its combustion utilised for the production of fresh supplies of HCI. From the H 2 S so produced not only are fresh supplies of HCI obtained during the process by the treatment of sodiumchloride with the sulphur-dioxide (SO 2 ) resulting from the use of the H 2 S as fuel, but also from the sodium-chloride certain by-products in the form of caustic soda and other soda products. Portions of such products are used for the recovery of the metals from the aqueous chlorides obtained in the first part of the process, and any excess can be dealt with for commercial purposes. In order to make my invention entirely clear I propose to explain the same by the accompanying drawings, in which is shown apparatus for carrying it into effect. The sulphide ore as taken from the mine-floors, and without reducing it to a finely-divided state, is placed in suitable vats or digesters A, lined with copper or other suitable material capable of resisting the action of corrosive acids. These digesters A, with their accompanying appliances, as hereinafter described, are arranged in series of any suitable number, and they may be of any suitable size. They are provided with gastight lids, and their bottoms are covered with copper gratings A l , arranged in three tiers one over the other. The openings in the gratings are graduated, the topmost being largest, so that only fine particles of ore can pass through the lowest one into a crucible B placed below. These crucibles B are provided with heating apparatus C l , which consists preferably of gas-jets supplied from a gasometer N through the pipe C, as hereinafter more particularly described. The digesters A having been charged with raw sulphide ore, and the gastight covers replaced, aqueous HCI is introduced from a storage-tank D, and sprayed into the upper portions of the digester A, whilst at the same time HCI gas from a generator Eis discharged immediately
181
G.—3
underneath the copper gratings A l . By the combined action of the aqueous and gaseous HCI the ore. is gradually disintegrated, and passes, with the aqueous HCI, through the gratings A 1 into the crucible B. The crucible Bis constantly heated in order to maintain the aqueous HCI, which now contains metallic chlorides of lead and zinc at the boiling-point. The digesters A and crucibles B being arranged in series, the aqueous HCI is discharged from the crucible B, No. 1, and raised by any suitable means into the tank D, No. 2 of the series, leaving the gangue and any partiallyundecomposed ore with the adhering silver-chloride in the crucible. From tank D, No. 2, it is sprayed as before over the ore in the No. 2 digester, and is passed in this way from one digester to another until the HCI has become neutralised and a neutral saturated solution of metallic chlorides of lead and zinc obtained. This saturated solution is then returned to crucible B, No. lof the series. In the meantime the whole of the ore contents of the digester A have become disintegrated, and have passed into the crucible B. The digester A, No. lof the series, is then disconnected, and No. 2 in the series now becomes the first, and the digester A, when refilled, the last of the series, and so on in turn, the order always changing as each digester is emptied and refilled with supplies of raw ore for treatment. . Having detailed the circulation of the aqueous HCI, and its return in the form of neutralised solution of metallic chloride of lead and zinc, before detailing its further treatment for the recovery of the metals I will explain the circulation of the gaseous HCI. The gaseous HCI rising through the contents of the digester A, No. 1, liberates H 2 S by its action upon the sulphides of the ore. The gases so formed in digester No. 1 are carried by suitable pipeconnections, and are discharged underneath the copper gratings of digester A l , No. 2 in the series. After passing through the ore in the digester No. 2, they pass to the next in the series, and so on until the HCI gas becomes neutralised and the H 2 S practically free from HCI. To eliminate, any final traces of HCI the gases are conducted through a purifying-chamber S filled with crushed antimony-blende, and the pure H 2 S led for storage purposes into a gasometer Nof any ordinary construction. From the gasometer N the H 2 S is drawn for use as fuel wherever required, it being intended that the H 2 S so obtained shall be used for all purposes for which heat is required, thereby effecting a considerable saving in fuel. The products of the combustion of the H 3 S as fuel, which are sulphurdioxide (SO 2 ) and aqueous vapour mixed with nitrogen from the air, are collected by means of suitable flues, then passed through drying-towers F for extraction of the aqueous vapour, as hereinafter more particularly referred to, and finally discharged into cylinders R arranged conveniently to the digesters A. The cylinders R are filled with briquettes of sodium-chloride, and are maintained at a temperature of about 500° C. By the action of S0 2 , together with air and steam upon the sodiumchloride in the cylinders R, HCI gas is evolved, and sodium-sulphate, or salt cake, produced as a residue or by-product. The latter is subsequently removed and heated with carbon in the ordinary way in order to produce sodium-sulphide for use in the recovery of zinc, as hereinafter described in a subsequent portion of the process, or converted by any known process into caustic soda and other soda products. The HCI gas from the generating-cylinders Ris conducted into a suitable tower L, through which a continual stream of brine, obtained in the manner hereinafter described, is being passed from a reservoir X placed overhead. By the action of the gaseous HCI upon the brine sodium-chloride is precipitated, and aqueous HCI is produced. The aqueous HCI is collected in a suitable receptacle L 2 at the base of the tower, and is carried from this to the aqueous HCI storagetank D for use in the continuance of the process the nitrogen which has passed with the gaseous HCI from the cylinders R being meanwhile drawn off by a chimney-stack, or otherwise eliminated. Returning to the former portion of the process, the contents of the crucible B, No. 1 of the series, now consist of disintegrated particles of gangue and undecomposed ore (which may be blende, galena, or argentiferous galena), with which has remained the insoluble silver-chloride, and of the concentrated solution of aqueous zinc- and lead-chlorides, which has been returned thereto after the circulation as detailed. The temperature of the mass in the crucible is gradually raised until it reaches about 300° Celsius. The lead- and zinc-chlorides, as the heat rises, gradually fuse, and by the action of the fused zinc-chloride the silver-chloride dissolves in the fused mass. The fused mass of chlorides having a specific gravity of about 4, any particles of ore still undecomposed sink to the bottom of the crucible, and can be removed later for further treatment. The gangue meanwhile becomes suspended in the fused mass of chlorides, and the whole is removed whilst still hot to suitable closed drying-towers P. The towers F are preferably placed within a water-tank F l , so that the heat evolved by the hydroscopic action of the zinc-chloride may be absorbed by the water, which latter is used as may be required in other parts of the process. Into the upper portion of these drying-towers F the S0 2 aqueous vapour, and other products of combustion of the H 2 S, are discharged from the collectingflues as before described. The aqueous vapour is then absorbed by and dissolves the soluble metallic chlorides, whilst at the same time any chloride of gold in the fused mass is reduced to the metal state by sulphurous anhydride. The fused mass (as the chlorides are dis solved by the aqueous vapour) passes through gratings at the bottom of the drying-towers P into a lower chamber, where it is boiled with water acidulated with HCI. The hot aqueous solution of chlorides, together with the gangue, is then drawn off into a lixiviating-tank, which forms the first of a series of precipitating-tanks. As the gangue settles the aqueous chlorides are drawn off into a second or cooling-tank. The residue of gangueleft in the first tank is then washed with boiling water until free from lead-chloride. The first tank now contains gangue, metallic cold, and silver-chloride, which may be recovered by any well-known means. The liquor drawn off from the first tank, together with the washings, is now placed into a second or cooling-tank, and the lead-chloride settles out. When the liquor in the second tank has cooled down the clear liquor is removed to the third tank of the series. In this any remaining traces of lead-chloride are decomposed by means of sodium-sulphate obtained from the HCI generators R. Lead-sulphate is thus precipitated, and the sodium-sulphate contained in the solution becomes sodium-chloride, The

liquor from this third tank is conveyed to the fourth of the series, which is fitted with a revolving stirring-gear having long rods of metallic zinc whereby the whole of the copper is precipitated. The liquor is then removed to the fifth tank in the series, where it is oxidized by any suitable means until the ferrous iron is converted into ferric iron, when it is treated with a solution of caustic soda, and boiled. By this means the whole of the remaining metallic chlorides are decomposed into hydroxides, and the sodium-chloride regenerated. The liquor, which still contains zinc and manganese, is aerated, and thereby the manganese is thrown down as manganese-dioxide, which can be used in the production of chlorine. The liquor is then removed to a sixth tank, wherein the whole of the zinc, in the form of zinc-sulphide, is precipitated by means of sodic sulphide, or recovered by any well-known means. This sodium-sulphide has been obtained by heating with carbon the salt-cake or sodiumsulphate resulting from the regeneration of the HCI in the cylinders R, as before described. The zinc-sulphide may, if desired, be converted into zinc-oxide for use in any zinc electrolysing tank in order to maintain the strength of the solution and to keep it neutral. The liquor in the final tank, now only an alkaline brine, is raised by any suitable means into a brine-tank X, placed at the top of a tower L, for the production of sodium-chloride and aqueous HCI, as hereinbefore described. In my invention as detailed herein there are, as will be perceived, three distinct circulations : Firstly, the circulation of the aqueous HCI through the series of digesters containing raw sulphide ore, and its return to the first of the series of crucibles in the form of saturated solution of lead- and zinc-chlorides for the fusion of the silver-chloride in the ore. Secondly, the circulation of the gaseous HCI through the several digesters containing crude ore until it has become neutralised, and the H 2 S resulting from its action on the sulphides in the ore has after use as fuel been returned as S0 2 , which by the use of sodium-chloride has been returned to the tanks as HCI, both in a gaseous and aqueous form. Thirdly, the circulation of the sodium-chloride, comprising, first, its use in generators for the production of gaseous HCI, then in the lixiviating-tanks in the form of sodiumsulphate and caustic soda for precipitation purposes, its subsequent regeneration as sodium-chloride, and final recovery in the aqueous HCI towers for fresh use in the gaseous HCI generators. In the above description the process is detailed as relating to zinciferous sulphide ores. In the treatment of galena and argentiferous galena, zinc-chloride is first fused in the crucible, and the raw ore in a finely-divided state, either alone, but preferably mixed with lead-sulphate and lead-oxide, poured therein. The lead in the ore is reduced, and sinks to the bottom of the crucible as metallic lead, whereas the gangue, with adhering silver-chloride, rises, and becomes admixed with the fused chloride of zinc. The fused mass is then removed for the recovery of the silver and zinc, in the manner hereinbefore described, and the lead poured off into suitable cakes. I am well aware that the various parts of my process, either singly or in certain combinations, are well known, and wish it to be well understood that I do not claim as my invention any one of them, singly or specifically, or any two or more of them together in any combination whatever except in the particular combinations indicated. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. In the treatment of argentiferous sulphide ores, the within-described process, consisting of their disintegration by the combined action of aqueous and gaseous hydrochloric acid (HCI), at the same time causing the aqueous hydrochloric acid (HCI) to circulate through fresh supplies of raw ore until it has become a saturated solution of lead and zinc metallic chlorides, subsequently returning such solution to the wholly or pa.rtly disintegrated ore, and fusing by heat the whole of the chlorides in the disintegrated mass. 2. In the treatment of argentiferous sulphide ores in which the ore has been wholly or partially disintegrated by the combined action of aqueous and gaseous hydrochloric acid (HCI), the separation of the undecomposed ore for further treatment by fusing the whole of the chlorides produced in such disintegration, such fusion resulting in the admixture of the gangue with the fused mass, and the settling of the undecomposed ore to the bottom of the crucible. 3. In the treatment of argentiferous sulphide ore in which the chlorides formed by the disintegration of the ore by the action of hydrochloric acid (HCI) have been fused, as set forth in claim No. 1, the subsequent process for the recovery of the metallic contents of the fused mass, consisting in the application of aqueous vapour and sulphur-dioxide (SO 2 ), whereby the metallic contents are obtained as an aqueous chloride solution; subsequently boiling the same in water acidulated with hydrochloric acid (HCl); and finally precipitating the metals therefrom by any known process in suitable precipitating-tanks. 4. In'the treatment of argentiferous sulphide ores, the within-described process, consisting of the production of sulphuretted hydrogen (H 2 S) by the action of gaseous hydrochloric acid (HCI) upon the sulphides of the ore under treatment, the subsequent utilisation of the aqueous vapour accompanying the sulphur-dioxide (SO 2 ) resulting from the combustion of the sulphuretted hydrogen (H 2 S) for the purposes of dissolving in a suitable drying-chamber the fused chlorides obtained in the manner as set forth in claim No. 1. 5. In the treatment of argentiferous sulphide ores, the within-described process, consisting of the production of sulphuretted hydrogen (H 2 S) by the action of the gaseous hydrochloric acid (HCI) upon the sulphides of the ore under treatment, the use of the sulphuretted hydrogen (H 2 B) so obtained as fuel, and the subsequentutilisation of the sulphur-dioxide (SO 2 ) resulting from the combustion of the same for the treatment of sodium-chloride in the production of fresh supplies of gaseous hydrochloric acid (HCI) for use in the disintegration of ore. 6. In the treatment of argentiferous sulphide ores, the within-described process, consisting of the obtaining of sulphur-dioxide (SO 2 ) by the combustion of sulphuretted hydrogen (H 2 S) resulting from the action of gaseous hydrochloric acid (HCI) upon the sulphides of the ore under trea>

ment, the subsequent treatment of sodium-chloride by the sulphur-dioxide (SO 2 ) so obtained for the production of gaseous hydrochloric acid (HCI), subsequently treating with the gaseous hydrochloric acid (HCI) so obtained salt brine taken from the last of the series of lixiviatingtanks, whereby aqueous hydrochloric acid (HCI) is obtained, and sodium-chloride recovered for renewed use during the process. 7. In the treatment of galena and argentiferous galena, the within-described process, consisting of pouring the raw ore in a finely-divided state, either alone, but preferably mixed with load-sulphate and lead-oxide, into a bath of fused zinc-chloride, whereby the lead is thrown down as metallic lead, and the silver-chloride, with the gangue, becomes admixed with the fused chloride of zinc, the fused mass being subsequently removed for the recovery of the silver and zinc in the manner hereinbefore described.

A Process for extracting Precious Metals from Refractory Ores by Means of Antimony, and for Recovery of Antimony employed. I, James Woolford, of No. 659, Commercial Road East, in the County of London, England, metallurgist, do hereby declare the nature of my invention for " A Process for extracting Precious Metals from Refractory Ores by Means of Antimony, and for Recovery of the Antimony employed," and in what manner the same is to be used and performed, to be particularly described and ascertained by the following statement : — My invention relates to the extraction of precious metals from refractory ores by treating with antimony-oxides, and to the recovery of the antimony employed in this treatment. The ore, whether in its natural state or in the state of clinkers after roasting or other treatment, is crushed, and thoroughly mixed with an equal weight of antimony-trioxide, with half its weight of the residue from reduction of antimony-oxide, and with half its weight of finely-pulverised coal or charcoal. The mixture being fused in a cupola or other suitable furnace, the antimonyoxide is reduced, and the antimony forms an alloy with the precious metal. This alloy is tapped off, and treated in an oxidizing furnace the bed of which is glazed with a mixture of borax and sulphate of soda. In this furnace the antimony becomes oxidized, the oxide passing away as fumes, while the precious metal remains on the bed of the furnace. Successive batches of the alloy may be treated until there is accumulation of the precious metal sufficient for being run off. The combustion-gases, with the fumes of antimony-oxide, are drawn by a fan through coolingpassages and depositing-chambers, in which a large proportion of the oxide is deposited. In order to recover the last portions of the oxide, and clear the gases from it, I employ, in conjuncton with the fan which creates the draught through the cooling-passages and depositing-chambers, a nozzle furnishing a water-spray which mingles with the gases and fumes, and is effectually mixed up with them by the blades of the fan. The water, with the oxide suspended in it, is drawn away from the lower part of the fan, while the gases pass away to a chimney or elsewhere almost entirely free from fumes. Fig. lof the accompanying drawings is an elevation partly in section, and Fig. 2is a transverse section of the fan and water-nozzle ; A is the conduit leading the fumes from the depositing-chambers and cooling-passages to the suction-fan, B. In the passage A is arranged a distributing-nozzle E, by which water is sent in spray to mingle with the fumes as they enter the fan, the blades of which break up the water and dash it about along with the fumes, causing separation of the particles suspended in them. While the gases thus cleared of the suspended particles pass away by the conduit C to a chimney or other discharge, the water mixed with the solid particles collects in the lower part of the fan, and flows out to depositing-tanks D, in which the solid material is collected. Instead of sending water alone by the nozzle E, water mingled with steam may be sent into the conduit, the steam being used as an injector-jet to cause the water to leave the nozzle with great speed and in a greatly-subdivided condition. The oxide collected in the cooling-passages and deposit-chambers, as well as that removed from the depositing-tanks D, and dried, may be used to treat fresh batches of ore, or may be reduced in any known way, so as to obtain metallic antimony. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The herein-described process for extracting precious metals from refractory ores by fusing the crushed ore intimately mixed with antimony-oxides and pulverised fuel, thus producing an alloy of antimony with the precious metals, treating the alloy in a suitable furnace, thereby oxidizing the antimony and driving the oxide off as fumes, leaving the precious metals on the furnace-bed. 2. The herein - described method of recovering the antimony by causing the combustiongases and fumes to pass from the oxidizing - furnace through cooling - passages and depositingchambers by means of a fan, wherein the gases and residuary fumes are mixed with water, and whence tbe gases pass away, while the oxide, suspended in water, is drawn off to depositingchambers.

Improvements in Apparatus for the Recovery of Precious Metals from their Solutions. I, Henry Livingstone Sulman, at present residing at Day Dawn, Murchison Goldfields, Western Australia, metallurgist and analytical chemist, do hereby declare the nature of my invention for
G.—3

"Improvements in Apparatus for the Recovery of Precious Metals from their Solutions," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — My invention has for its object the recovery of precious metals, such as silver, gold, platinum, &c, from solutions of the same by means of a new and improved apparatus, the apparatus being constructed to effect the deposition or " precipitation " of the precious metal or metals in solution upon a "precipitating" substance, or " precipitant," which is in a solid but more or less finelydivided state. The apparatus, for instance, is designed to recover gold, silver, platinum, &c, from solutions of their haloid by means of the employment therein of dense but more or less finely-divided carbon, subsulphide of copper, or other known solid and suitable precipitant; again, also, for the recovery of the same metals from their cyanide-solutions by means of the finely-divided zinc product commercially known as " zinc fume," and generally for analogous requirements. It is necessary that whenever the nature of the precipitant used and the degree of fineness to which it is found desirable to reduce it primarily, it shall be of greater specific gravity than the liquid or solution desired to be precipitated by it, so that the precipitant shall tend to settle from the liquor by gravitation. Further, it is necessary to my invention that the solution or liquor to be precipitated shall percolate upwards through the mass of solid finely-divided precipitant. In an apparatus with parallel vertical sides the upward flow of liquor would tend to carry off finely-divided particles of precipitant, unless special means were taken to prevent this. Filters tend to become clogged, and are generally useless for my purpose, so that I retain the particles of the solid precipitant upon whose surfaces the precious metals are in course of deposition within my apparatus by inducing subsidence of them. This I effect by continually reducing the upward rate of liquor-flow, which is secured by constantly increasing the area of the liquor-column as it rises higher in the apparatus. My apparatus takes the form of a funnel. The liquor enters (under a sufficient pressure or head) through the bottom orifice ; it then meets with and thoroughly mixes with the mass of finelydivided precipitant in a condition of suspension in the liquor. The solid finely-divided particles do not sink against the comparatively rapid inflow, or are prevented from so doing to any extent by means of an automatic valve of ordinary type. By this intimate admixture of liquor with precipitant the deposition of the precious metal in solution in the former is effected upon the minute surfaces of the latter. It only now remains to remove the depleted liquor from the particles of the solid " precipitate " containing the gold, silver, &c. As the liquor continues its upward flow, by virtue of the continually-diverging sides of the apparatus the area of the liquid column becomes greater and greater; the rate of the vertical upflow is thereby correspondingly reduced. This continues until a point is reached at which the upflow is so vertically slow that the finest particles are able to settle or subside against it. At any point, therefore, above this limit or zone the absolutely clear liquid may be drawn off from the apparatus free from suspended particles, and depleted of its precious-metal contents. I do not confine myself to any special section of the funnel in a horizontal direction : it may be square or polyangular, oval, &c.; but I prefer it for many purposes circular, as giving more uniform admixture and flow throughout the whole space. If the precipitation of the precious metals be deemed to be incomplete in one apparatus, owing to the richness of the original liquor or to other causes, the outflow may be caused to pass into a second similarly-arranged apparatus, or through two or more such apparatus placed in series; but in general one apparatus can be made to secure practically complete removal of the precious metals dissolved in a given liquor, by the use of a suitable precipitant. If a series of two or more such apparatus be employed, the first of the series may be used to enrich quantities of precipitant which have been only partially used up to their fullest capacity of precipitating the precious metals ; whilst the succeeding members of the series are supplied with the necessary amounts of less rich or quite fresh precipitant in order to remove any remaining traces of gold, silver, &c, which may escape unprecipitated in the outflow from the first apparatus. The poorer precipitates in these last apparatus are in course of time removed through the bottom of the apparatus, and transferred to the first one of the series, there to be enriched to their full capacity, whilst their place is taken by fresh quantities of poorer or quite unused precipitating agent, and so on. When the precipitate is deemed to be sufficiently rich it is removed from the apparatus by a " three-way cock" at the bottom thereof, or any other suitable arrangement, and the precious metal it contains finally recovered by any known and suitable method, such as, in the case of the employment of a carbon precipitant, by burning, or, in case of the use of a zinc precipitant, by smelting. The apparatus is also supplied with a small central funnel for the introduction of fresh quantities of precipitant from time to time to the point of maximum precipitating action in the apparatus—i.e., near the inflow. By providing this funnel with a bell-shaped or inverted-funnel termination a sort of " chamber" is produced in the lower part of the apparatus, having an annular space for the passage of liquor between the rim of the smaller funnel and the sides of the large one. This chamber is of considerable aid in promoting the action of the precipitant by keeping the bulk of it constantly near the liquor-inflow, and.securing perfect admixture by means of the vortex currents, &c, it induces. It is further desirable to break the rapid rush of inflowing liquors at their point of entry into the apparatus, and to secure their subdivision and intimate admixture with precipitant as early as possible. This I effect by capping the end of the inlet-pipe with a small perforated cone or distributor. The perforations may be from one-quarter to one-tenth the diameter of the inlet-pipe, but their total area must be larger than that of the sectional area of the pipe. The holes may be bored
185
C.—3
in a direction perpendicular to the cap-cone, or they may be made tangential— i.e., bored at a tangent to the internal circumference of the cone, thus securing a rotary initial flow of the inflowing liquors, instead of a series of straight ones. In the majority of cases, however, perpendicular boreholes answer equally well. The clear precipitated liquor may be drawn off at any point above the limit of subsidence, either by a pipe or, preferably, by allowing it to flow equally over the rim-circumference of the apparatus. The latter method secures the quieter and more uniform outflow, and does not disturb the top layers of liquor, undergoing final subsidence, by establishing a quick current in one particular direction. If desired, the rim may be encircled with a filter-screen of lawn, calico, or other filtering or straining medium, so as to retain within the apparatus any particles of precipitant which may be floated or buoyed up by-bubbles of air or other gas. The clear liquors passing over the rim and through the precautionary filter or strainer fall into and are collected by a circular trough or launder attached to the apparatus below the rim, whence they are conveyed away by a pipe. As before stated, this may lead into a storage-vat or into another similar apparatus ; or, if deposition of the floating particles is not absolutely complete, into any suitable known type of apparatus (such as, for example, the slat-partitioned tank, used for freeing softened water from traces of deposit) where subsidence is finally rendered absolute. In most cases where traces of precipitant have escaped I have secured perfect final subsidence by allowing the liquors to flow through a shallow plain tank of from four to six times the area of the top of the precipitating apparatus, before passing them direct to the storage liquor-vats. Such an apparatus as I have described I term a " precipitating cone." It may be constructed of any suitable material, such as wood, stoneware, galvanised iron, &c, according to the nature of the liquor or precipitant it is designed to treat. Its action, until the charge of precipitant it contains is exhausted and requires renewal, is perfectly automatic and continuous. Its capacity, its height, the angle of its sides, the ratio of inflow-diameter pipe to top area of cone, will naturally vary with the volume of liquor to be dealt with, the rate and head of liquor-inflow, the relation of the specific gravity of the liquor to that of the finely-divided precipitant, the actual coarseness or fineness of the particles of the latter, and so on. These data maybe calculated, or decided by preliminary experiment in any particular case. As an example, however, of the application of my invention to the recovery of gold bullion from cyanide solutions, I instance the following dimensions of my apparatus : For a flow of from 600 to 800 gallons per hour I find a cone-depth of 5 ft., with a top diameter of 5 ft. also, to be amply sufficient. The diameter of the inlet-pipe is from 1-J-in. to If in., according to the head of the inlet liquor, whilst the perforations of the cap-cone, or distributor, are rVin. in diameter. The charge of zinc fume in such an apparatus varies from 51b. to 301b., according to requirements. In order that my apparatus and invention may be more readily understood, I append hereto a diagram, representing a vertical section through such a precipitating cone as before described, and whereof the following are the lettered references : A, inlet-cock ; B, precipitating-cone ; C, perforated distributor ;D, supply-funnel for precipitant; E, check-valve ;F, supply for liquor or discbarge for rich precipitant operated by a three-way cock; G, check-valve guide-rod, also giving independent control of valve ; H, cone overflow ; J, precautionary filter-screen for precipitated liquors ; X, collecting-launder ; L, outflow for same; M, inlet-pipe; N, cock for emptying cone after use; P, level (variable) of bulk precipitant on filling in before liquor-inflow. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The use of a precipitating apparatus of constantly-increasing area in a vertical direction, whereby the vertical upward flow of a liquor or solution introduced at the bottom of such becomes continually slower until the deposition or subsidence of any suspended particle of solid precipitating agent becomes possible against such greatly-reduced current, substantially as described. 2. The use in combination with such apparatus of known solid precipitants, for the solutions of precious metals, when in a more or less finely-divided condition, substantially as decribed. 3. The use of two or more such apparatus placed in series for the purpose of utilising to any required degree the precipitating power or capacity of the precipitating agent used, substantially as described. 4. The combination of such apparatus with other known types of depositing or subsidence apparatus, substantially as described. 5. In such apparatus, the use of a tangentially or otherwise perforated distributing-cone for breaking up inflow-liquor, substantially as described. 6. In such apparatus, the use of a smaller cone inverted towards the greater cone, but not touching the same, providing thus a "mixing-chamber " with an annular outflow, substantially as described. 7. In such apparatus the use of a filter-screen at the top thereof to retain floating or buoyed - up particles of precipitant, substantially as described. Dated this 21st day of August, 1896. W. E.

An Lmproved Process for the Treatment of Metalliferous Ores and Products. I, Edgar Arthur Ashcroft, of 34, Queen Street, Melbourne, in the Colony of Victoria, electrical engineer, do hereby declare the nature of my invention for "An Improved Process for the Treatment of Metalliferous Ores and Products," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : —
C.—3
186
This invention relates to the treatment of ores and products containing copper and iron, in conjunction with the combined leaching and electrolytic treatment of ores and products containing zinc. My improved process is carried out in a manner and with apparatus very similar to my former process, as described in detail in the specification of previous Letters Patent, dated the 20th day of June, 1894, No. 6914, and the 18th day of October, 1895, No. 7985. The essential improvements now made consist in working in conjunction with the zinc-bearing ores and products other ores and products, especially products containing copper and iron, such as are obtained from iron- and copper-pyrites or sulphide ores by means of the preliminary furnacetreatment almost universally employed in the treatment of such ores. These products—viz., copper and iron mattes, regulus, or crude copper—can, by the method under review, be employed as a substitute for a portion of the iron anodes required m my process above referred to, and in such employment, while effecting an economy in the treatment of the zinc-bearing ores, are themselves cheaply treated for the recovery of their valuable constituents. In carrying this improved process into effect I operate in a similar manner, and with similar apparatus, and with the same solutions as in the former patented process, with the exception that I substitute for the iron anodes (either entirely or partially) anodes consisting of the iron- and copper-bearing mattes, regulus, or crude metal above mentioned. The metals in this material may occur in various proportions to each other, but it is immaterial for the purpose of this invention what those proportions are, except in so far as may be determined by economical considerations. In operating with anodes of this description, the gold, silver, and sulphur of the anode are set free in solid form, while iron and copper are imparted to the solution in amounts depending on the composition of the anodes. Whilst the products of the electrolysis of the anodes are being dissolved as in the formerly-patented process, pure zinc is being deposited at the cathode as before. The copper imparted to the solution may be removed therefrom by electrolysis, and ferrous salts contained in another batch of the solution may in such electrolysis be simultaneously raised to the ferric state, the electrolysis being performed in vats having insoluble anodes and copper cathodes separated by diaphragms. The copper thus produced is refined copper, and the ferric-salt solution is regenerated leaching-solution suitable for leaching zinc-bearing ores. It will be seen that cathodes of other conducting materials than copper may be used if desired. In certain cases it may be preferred to take the whole or a part of the copper out of the solution by the simple contact of metallic iron (known as the cementation method), in which case an equivalent of iron is dissolved for the copper precipitated. In other cases copper may be deposited at the cathode whilst metallic iron anodes become dissolved, and the superabundant electromotive force then developed may be usefully employed to aid the operation of depositing zinc by connecting such vats in the same electrical circuit as the vats wherein the zinc is deposited. In cases where pure zinc is to be deposited it will be necessary to employ diaphragms, but in certain cases where products of convenient composition are being operated upon diaphragms may be dispensed with, and the proportion of the different metallic salts in solution may be maintained sufficiently constant to insure a uniform product—viz., an alloy of the different metals of a uniform composition. It is unnecessary to more minutely describe the methods herein explained, as they will be readily understood by any person properly versed in the art to which they appertain on reference to the former patent referred to ; but to facilitate reference I here incorporate certain portions of the previous specification. The operation of leaching the zinc-bearing ore or product is the same as before—that is to say, the ore, if it contain zinc-sulphide, is first subjected to an oxidizing roast, whereby the zincsulphide is converted as far as possible to neutral or basic zinc-sulphate and zinc-oxide ; any leadsulphide contained also undergoing oxidation more or less completely. In the case of ores or products containing zinc only in the form of oxide, such roasting will be unnecessary. The ore or product having been ground to extreme fineness (which may be done either before or after roasting) is then subjected in properly-proportioned quantity to the action of a leaching solution containing ferric salt, as hereinafter specified, the reaction between the finely-ground ore or product and the solution being promoted by maintaining the same in a constant state of agitation by stirring or otherwise, this operation being continued for from half an hour to two hours, and the proportional quantity of ore and solution being so calculated that the reaction with all the iron-salt in the solution will be complete when so much zinc has been extracted from the ore that the residue left is of good composition for subsequent smelting. For instance, with ores containing 30 per cent, of zinc probably some 5 per cent, would be allowed to remain in the residues, on account of the higher cost of total extraction. The solution, after being separated from the residues, may contain a small quantity of silver, gold, copper, antimony, arsenic, manganese, alumina, silica, and other foreign matters taken from the ore, also a small quantity of iron in the form of soluble ferric hydrate, which foreign matters I prefer to remove by well-known means before subjecting the solution to electrolysis. The solution, having been brought to the condition indicated, is now to be treated in the zinc electro-depositing plant, where the zinc is recovered, and the solution is recharged with ferric salts, so as to render it fit for use again in the above-described operation of leaching. The electro-depositing apparatus consists essentially of a number of depositing-vats provided with anodes of copper and iron, and suitable cathodes (preferably zinc plates), and a number of similar vats having anodes of insoluble material, such as carbon, the total depositing-capacity of the plates in the iron-anode vats being about twice that of the carbon-anode vats. Diaphragms of porous material are placed between the anode and the cathode plates, so as to divide each vat into a number of separate cells permitting the passage of the current without allowing the intermingling of the liquids.

The form and arrangement of the depositing-vats is not material, but one arrangement which I have found suitable is shown in the accompanying drawings. Any suitable number of such sets of apparatus may be employed, and the connection and arrangement of the same may be varied to suit particular conditions and requirements. Figure 1 is a section of a leaching-vat with stirrers. Figure 2 shows the arrangement of electro-depositing vats in a cascade, and the reservoir. Figure 3is a general plan of the electrolysis plant. The electro-depositing vats are arranged in such a manner, and with such pipe- and troughconnections between them, that a continual circulation of solution in three separate stages of progress is maintained in the system, the liquids being preferably circulated at sufficient speed to insure a brisk and continual motion at every part of the plates. The depositing apparatus consists of a series of any number of electrolysis vats — A l , A 2, A 3 , A 4, A 5, A 6, A 7, A B , A 9 —preferably arranged as shown in Figures 2 and 3 ; and a number of reservoirs—B 1 , B a , 88,B 8 , 84,B 4 , 85,B 5 , 86.B 6 . Each of the vats is divided by diaphragms Cof filter-cloth or other suitable material into a number of compartments, each of which has an inlet-pipe D, entering near the bottom, and an outlet-pipe E, discharging near the top. Each of the vats A l , A 2, A B , A 4, A 5, A 6 contains three copper and iron anodes H, and two metallic cathodes X; while each of the vats A 7, A B , A 9, contains three carbon anodes M, and two cathodes K. The electrical connections may be made in any suitable manner, all the plates in the same vat being connected in parallel, and the plates of successive vats being connected in series. The reservoir B 1 has a number of exit-pipes which discharge into the inlets of the cathode compartments of the three upper vats A l , A 4, and A 7. The outlet-pipes of these compartments discharge into the inlets of the cathode compartments of the vats A 2, A B , and A B . The outlet-pipes of these compartments discharge into the inlets of the cathode compartments of the vats A B , A 6, and A 9, and the outlet-pipes of these compartments discharge into the reservoir 82.B 2 . The reservoir B 3 has a number of exit-pipes which discharge into the inlets of the anode compartments of the vats A 1 and A 4. The outlet-pipes of these compartments discharge into the inlets of the anode compartments of the next vats, A 2 and A 5. The outlet-pipes of these compartments discharge into the anode compartments of the vats A 3 and A 6, and the outlet-pipes of these compartments discharge into the reservoir 84.B 4 . The reservoir B 5 has exit-pipes which discharge into the inlets of the carbon-anode compartments of the vat A 7. The outlet-pipes of these compartments discharge into the inlets of the carbon-anode compartments of the vat A B . The outlet-pipes of these compartments discharge into the outlets of the carbon-anode compartments of the vat A 9, and the outletpipes of these compartments discharge into the reservoir 86.B 6 . For the above-described operations one of several solutions of different, though analogous, compositions may be employed according to varying circumstances : No. 1, zinc-chloride mixed with sodium-, potassium-, magnesium-, or ammonium-sulphate. No. 2, zinc-chloride mixed with sodium-, potassium-, magnesium-, or ammonium-chloride. No. 3, zinc-sulphate mixed with sodium-, potassium-, magnesium-, or am-monium-sulphate. The ferric salt required in each of the above solutions in order to effect the solution of the zinc is generated in the electro-depositing plant as hereinbefore described. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The improved process whereby a solution containing copper and iron is obtained electrolytically by employing in a zinc-depositing vat an anode consisting of the products resulting from the preliminary furnace-treatment of products or ores containing copper and iron, substantially as described. 2. The improved process whereby from a solution obtained by the process claimed in the first claim hereof the copper is deposited and the dissolved iron simultaneously raised to the ferric state by the use, in an electrolytic vat, of copper or other cathodes in conjunction with carbon or other insoluble anodes, substantially as described. 3. The improved process consisting in including in one and the same electrical circuit vats in which the electro-deposition of zinc is proceeding, and vats provided with anodes of metallic iron and cathodes of metallic copper or otherwise in which copper is being electrolytically deposited from a solution obtained by the process claimed in the first claim, substantially as described. 4. The method of preparing from copper and other mattes containing iron a solution of a ferric salt for leaching roasted zinc-ore, substantially as described. Dated this 23rd day of October, 1896. W. E.

Improvement in the Treatment of Compounds or Ores containing Zinc. I, Edgar Arthur Ashcroft, of 34, Queen Street, Melbourne, in the Colony of Victoria, electrical engineer, do hereby declare the nature of my invention for " Improvement in the Treatment of Compounds or Ores containing Zinc," and in what manner the same is to be used and performed, to be particularly described and ascertained in and by the following statement: —■ The object of my invention is to obtain zinc from ores or compounds containing it in a cheaper and more convenient manner than heretofore by the aid of electrolysis. It is well known that zinc presents great difficulties in electro-deposition, inasmuch as it is liable to form irregular and spongy deposits. Acids or salts of the anode metal are set free at the anode, and must be either separated by porous diaphragms from the liquid around the cathode, or the solution must be continuously and rapidly changed in the electrolysis vats, and free acid or metal salts removed. I have discovered that the above hampering tendencies can be corrected by depositing zinc from solutions in which oxysalts are present to a sufficient amount. 1 have also discovered that precipitation of zinc from these solutions can be conveniently and more 25—C. 3.

economically carried out by employing the solutions at high temperatures. Also, that the oxidization of any reducing substances (such as may have been brought into the liquid during such operations as leaching the ore) prior to electrolyzing them materially assists in obtaining a good deposit, all of which matters are hereinafter more particularly set forth. Taking the ordinary case of solutions of zinc-chloride or zinc-sulphate or mixtures of the two (perferably with alkaline sulphates or chlorides), I have found that if oxychloride or oxysulphate of zinc, or both, be present and there be no other reducing agent in the liquid the deposit is even and firm, and wholly free from spongy zinc, as long as these oxysalts are present in the solution. Also, the oxysalts, by absorbing the sulphuric acid or chlorine set free at the anode, avoid the necessity of employing separating diaphragms, and enable the solution to be operated upon for an appreciable time before it becomes unfit for the operation. The time during which a given current can be passed through the solution before it is rendered unfit for electrolysis is greatly extended by employing the solution hot, which is, no doubt, due to the greater solubility of the oxysalts in the hot solution. I avail myself of this property of zinc by insuring that in the solution from which deposition is to take place there is a sufficiency of these oxysalts. The simplest method of obtaining this is by circulating the zinc solution hot, and mixing into it with a suitable agitator, zinc-oxide, with or without zinc-sulphate or -chloride, or both, so that oxychloride or oxysulphate of zinc, or both, may be formed. This solution is passed into the depositing-vats, where a firm and homogeneous deposit of zinc is obtained, and the acids set free at the anode are absorbed by the oxysalts. When the oxysalts are wholly or partially exhausted the solution is recharged with oxide of zinc, with or without sulphate or chloride of zinc, or both, as before, and may then be returned to the electrolysis vat, so that the process is a continuous one, the operation being preferably carried on with the solution at a high temperature. The oxide and other salts of zinc employed may be either in a more or less pure form, having been previously removed from the ore by known processes, in which cases the zinc-oxide and salts are simply added to the solution periodically, and will in course of time completely dissolve therein, or the roasted or otherwise prepared zinc-ore maybe added to the solution, when the zinc-oxide and zinc salts will be dissolved, leaving the other constituents of the ore as an insoluble residue. If the latter course be adopted, it is manifestly preferable to employ in the path of the circulating solution various other apparatus, such as settling-boxes for removing the solid residue, and zinc shaving-troughs for removing various other metals which may have gone into solution before the solution is again employed in the electrolysis vat. From the above it will be seen that the process is a continuous one, and may be used directly or indirectly to recover zinc from any kind of ore or product. In cases where previously-roasted ore is employed direct in the solution the ore may, if preferred, be added to the solution while still hot. It is evident that oxychloride or oxysulphate may be made independently, and the electrolytic solution charged with them when so made, and other variations may be made in the arrangements and methods of carrying out the process without departing from the invention. My present invention can be advantageously applied in conjunction with the process for obtaining zinc-oxide from zinc-sulphate described in the specification of Hampe and Schnabel. Such process consists in subjecting an intimate mixture of finely-divided carbon and finely-divided zinc-sulphate to an even and correctly-gauged temperature of 650° C. for about two hours. The zinc-oxide requisite for the formation of oxychloride or oxysulphate of zinc may be obtained by such process either directly from the ore, whether blende or mixed blende and galena, or from zinc-sulphate obtained from other sources. In obtaining the requisite zinc-oxide from blende or a mixed blende and galena I treat the ore, which is preferably previously roasted, with sulphuric acid, and obtain from the zinc-sulphate so formed zinc-oxide by the process described in the specification referred to. Further, the method discovered by me, and described in the specifications of letters patent dated the 20th day of June, 1894, No. 6914, and the 18th day of October, 1895, No. 7985, whereby from a roasted zinc-ore I obtain by leaching the same with a ferric-salt solution (either ferric chloride or ferric sulphate) a zinc-bearing solution, can be advantageously employed in conjunction with my present discovery. By applying my present discovery in combination with the processes referred to, as described in the specifications of the letters patent before mentioned, I am enabled to obtain directly from the ores, whether blende or a mixed blende and galena, a zinc-bearing solution containing the requisite quantity of oxysalt (whether oxychloride or oxysulphate) in solution. With this object in view, I leach a portion of the roasted ore with a ferric-salt solution, as described in the specification of letters patent dated the 18th day of October, 1895, No. 7985, and so obtain a zinc-bearing solution. To this solution I add from time to time, as required, zinc-oxide, obtained according to the process described in the specification of Hampe and Schnabel from other portions of the ore (preferably roasted). Having thus obtained a zinc-bearing solution and a quantity of zinc-oxide, which can be replenished from time to time, I prepare a solution of an oxysalt of zinc by the process described above in this specification. Should the ore from which the zinc-oxide is so obtained be a mixed blende and galena or an impure blende it is preferable to employ in the path of the circulating zinc-bearing solution apparatus such as settling-boxes for removing the solid residue which remains undissolved after the zinc-oxide has gone into solution. The anodes employed may be insoluble, such as carbon, or they may be of a soluble metal, such as iron, in which case it is preferable to oxidize and remove the iron salt from the solution by use of a jet of hot or cold air, or otherwise. The acid set free can be absorbed by zinc-oxide or oxysalts, and the basic salts and oxides of iron thrown down may be collected and removed from the solution.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The process whereby the formation of irregular or spongy deposits of zinc during the electrodeposition of that metal is prevented, consisting in dissolving in a zinc-bearing solution a quantity of zinc-oxide, substantially as described. 2. The process whereby an electrolyte consisting of a zinc-bearing solution in which an oxysalt of zinc is present in solution is prepared direct from blende or a mixed blende and galena, substantially as described. 3. The process whereby zinc can be continuously deposited from a zinc-bearing solution electrolytically, substantially as described. Dated this 24th day of August, 1896. W. E.

Improvement in the Treatment of Zinc- and Copper-ores. I, William Ernest Hughes, of 54, Lambton Quay, Wellington, in the Colony of New Zealand, patent agent, do hereby declare the nature of my invention for "Improvements in the Treatment of Zinc- and Copper-ores," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — My invention relates more particularly to the treatment of zinc- and, or, copper-bearing ores, or metallurgical products containing in the form of oxides the zinc or copper, or either of these metals alone or in combination with other metals. For convenience the term " ore " is used in the following specification, but it is understood to include raw or roasted ore, or metallurgical products containing zinc or copper in the form of oxides or basic or neutral sulphates or sulphites. My invention consists essentially in the conversion of the zinc-oxide (ZnO) and, or, copperoxide (CuO) contained in such ore into sulphate of zinc (ZnSO 4 ) and, or, sulphate of copper (CuSO 4 ) by means of ammonium-sulphate ((NH 4 ) 2 SO 4 ) and, or, ammonium-sulphamate, according to the formula: ZnO + (NH 4 ) 2 SO 4 = ZnS0 4 + 2 NH 3 -f H 2 O, the ammonia being given off in a gaseous form, and the ammonium-sulphate subsequently regenerated as hereinafter described. The sulphate of zinc and, or, the sulphate of copper so formed are leached out by water. Any copper present in the solution is precipitated by metallic zinc (spelter) according to the reaction : CuS0 4 + Zn = Cv + ZnS0 4 , or by other suitable means. The ammonia (NH 3 ) generated in the sulphatising operation is passed through the solution carrying the sulphate of zinc, precipitating the zinc as zinc-hydrate (ZnH 2 O 2 ) and regenerating the ammonium-sulphate for the treatment of further quantities of ore. The reaction takes place according to the following formula : ZnS0 4 + 2 H 2 O + 2 NH 3 = ZnHA + (NH 4 ) 2 SO 4 . In carrying my invention into effect the ore is mixed with its proper proportion of ammoniumsulphate and, or, -sulphamate, which I find in practice is about two units more or less of ammoniumsulphate and, or, -sulphamate to each unit of zinc in the ore, but do not bind myself to such proportions. The ore is then treated in suitable closed vessels and with or without the addition of water or steam, the contents of such vessels being raised to a temperature approximately 300° to 500° centigrade, or other suitable temperature. The reaction indicated then takes place, the zinc and copper being coverted in soluble sulphates and free ammonia-gas being given off. The product of this operation, consisting of sulphates of zinc and, or, copper, with gangue and, or, other insoluble residue, is leached with hot or cold water in suitable vessels. The soluble sulphates of zinc and copper are thereby dissolved, and are separated from the gangue and, or, insoluble residue, which may contain lead and, or, other metals. The gangue and, or, other insoluble residue can be treated by any well-known process for the recovery of its metallic contents. Any copper contained in the solution is precipitated by metallic zinc or other suitable means, and removed for treatment by any well-known process before precipitation of the zinc or zinchydrate by the ammonia-gas. Any iron in the solution can also be precipitated, if desired, by any suitable means. The ammonia-gas produced in the closed vessels during the first operation is recovered by being passed through suitable vats, towers, or other apparatus containing sulphate-of-zinc solution, preferably that obtained by leaching the product of the first operation. By the action of the ammonia the zinc in the solution is precipitated as zinc-hydrate (ZnH 2 O 2 ), and ammoniumsulphate ((NH 4 ) 2 50 4 ) regenerated. The hydrate of zinc is separated from the solution of ammoniumsulphate by filter-presses or other suitable means, and, after washing, drying, and, or, calcining, may be used either as a pigment or zinc-ore. The solution of ammonium-sulphate is evaporated down for recovery of ammonium-sulphate in the solid form for use in the treatment of further quantities of ore. My process can be carried into effect in any suitable apparatus. One convenient form is shown in the accompanying drawings, but is not claimed as part of my invention. Pig. I. is a longitudinal sectional elevation of the apparatus ; Fig. 11. a cross-sectional elevation of the same, upon the line X-X of Fig. I. The ore having been mixed with the proper proportion of ammonium-sulphate and, or, -sulphamate, is placed in a hopper A having an adjustable door or opening B, by means of which the feed is regulated. From the hopper A the ore is drawn into the retort Cby the action of revolving arms D carried on a shaft E. The arms D are preferably provided with adjustable shoes P, so that by altering their angle the material may be fed through the retort C at any desired rate. As the shaft E revolves the mixture is stirred and gradually carried through the retort C to the discharge-opening G. Through the discharge-opening G it falls into a closed hopper H provided with an adjustable door I, and again into a second closed hopper J having a door X, On the

190
hopper J being filled the door lis closed to prevent any ingress of air to retort C. The door Kis then opened, and the sulphatised material discharged into a truck, such as L, or other suitable arrangement for conveying the material to the leaching apparatus (not shown). During the operation steam or water may, if desired, be injected into the retort C through a pipe Rto facilitate the reaction. The retort Cis maintained at a suitable temperature, which may be from 300° to 500° centigrade, by means of a furnace such as M, or it may be provided with a jacket and heated by superheated steam. The ammonia-gas produced during the process in the retort C passes out through an opening N, and by the action of an injector 0 or other suitable means is forced through a pipe P into a vat, such as Q, or other suitable vessel, containing sulphate-of-zinc solution obtained by leaching the treated ore. In order to avoid loss of ammonia-gas by leakage the injector oor other suitable means should be so regulated as to maintain a slight vacuum in the retort. Ammonium-sulphate in solution is thereby regenerated, and can be evaporated to dryness for use in treatment of fresh quantities of ore. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is, — 1. In the treatment of ores as herein mentioned, the conversion of the zinc- and, or, copperoxides into sulphates of their respective metals by the action of sulphate and, or, sulphamate of ammonia. 2. In the treatment of ores as herein mentioned in which the zinc- and, or, copper-oxides have been converted into sulphates of their respective metals by the action of sulphate of ammonia and, or, sulphamate of ammonia, subsequently regenerating the ammonium-sulphate by passing the ammonia-gas produced during the first or sulphatising portion of the process through a solution of sulphate of zinc, substantially as specified. 3. In the treatment of ores as herein mentioned in which the zinc- and, or, copper-oxides have been converted into sulphates of their respective metals by the action of sulphate of ammonia and, or, sulphamate of ammonia, subsequently precipitating the zinc from its solution in the form of zinchydrate by passing through it ammonia-gas produced during the first or sulphatising portion of the process, substantially as specified. 4. In the treatment of ores as herein mentioned the within-described process, consisting in the conversion of the zinc- and, or, copper-oxides into sulphates of their respective metals by the action of sulphate and, or, sulphamate of ammonia, ammonia-gas being produced, then leaching by water the sulphates of zinc and, or, copper so obtained, and precipitatingthe copper, if any, and, or, iron, if any, by any usual means, subsequently passing the ammonia-gas produced during the sulphatising operation through the remaining solution of sulphate of zinc, whereby the zinc is precipitated as zinc-hydrate, and sulphate of ammonia is regenerated for the treatment of fresh supplies of ore, substantially as specified.

Improvements in the Extraction of Precious Metals prom their Ores or prom Compounds containing the same. I, James Mactear, of Victoria Mansions, London, England, chemical expert and engineer, do hereby declare the nature of my invention for " Improvements in the Extraction of Precious Metals from their Ores or from Compounds containing the same," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — This invention relates to the extraction of precious metals from their ores, or from compounds containing the same, by the use of a solvent having a more economical and advantageous action than those at present in use. The invention consists in the use, for the purpose of the invention, of a solution containing both cyanuric acid or a cyanurate and cyanide of potassium, or other cyanogen compound from which free hydrocyanic acid can be liberated by the addition of an acid or acid-salt or other substance or compound. The proportionate quantity of the cyanuric acid relatively to that of the cyanide present in the solution will depend to a large extent upon the physical condition of the ore or compound under treatment, as, for example, in ores in which the gold is fine and free five parts of cyanuric acid to each one hundred parts of the cyanide will be found to give good results, but in some cases even a less proportionate quantity of the cyanuric acid may be used; while with more refractory ores, or those in which the gold is coarser, a larger proportionate quantity of the cyanuric acid may be used ; but in very few cases will it be found necessary to use a greater proportionate quantity than twentyfive parts of the cyanuric acid to each one hundred parts of the cyanide. The presence in a cyanide or cyanogen compound solution of cyanuric acid, free or combined, renders such solution much more active as a solvent of the precious metals than are solutions of cyanides or cyanogen compounds not containing cyanuric acid, such as have hitherto been used, and which are hereinafter referred to as " ordinary cyanide solutions," the action of the cyanuric-acid-contained cyanide solution upon the gold or silver being such as to avoid to a very considerable extent the objectionable action of ordinary cyanide solutions upon the base metal compounds commonly found in ores or other compounds containing the precious metals, and which hinders the obtainment of the precious metals; and, being much more rapid than that of ordinary cyanide solutions, with a given quantity of cyanogen in each solution, the cyanuric-acid-contained cyanide solution being also of further advantage in relation to ordinary cyanide solutions in requiring a less quantity of cyanide to effect the extraction of a given quantity of precious metal, other conditions being the same.

When the gold is fine and free I treat the ore or other compound in a crushed or powdered condition to the action of the cyanuric-acid-contained cyanide solution in suitable containing vessels such as are usually employed in wet processes of extracting the precious metals, and separate the solution from the residue and the gold or silver from the solution by any usual or suitable methods or means ; but when the gold is coarse, or is partly coarse and partly fine, and water is scarce, I fit the solution-containing vessels with suitable stirring apparatus, and treat the powdered ore or compound to the action of the cyanuric-acid-contained cyanide solution in the presence of mercury or of an amalgam of mercury and sodium or potassium, whereby I obtain a ready amalgamation of the coarser particles of gold and solution of the finer particles thereof, which latter are then displaced by the sodium or potassium, and amalgamate with the mercury. When the ores carry much silver as sulphides it is best to have the solution more alkaline than when the ores carry only gold or silver in the metallic state. Tailings, concentrates, and refractory ores generally are especially susceptible to treatment by the cyanuric-acid-contained cyanide solution. Having now particularly described and ascertained the nature of the said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The extraction of precious metals from their ores, or from compounds containing the same, by the use of a solution of cyanide of potassium or other cyanide or cyanogen compound of the nature aforesaid containing cyanuric acid or a cyanurate. 2. The extraction of precious metals from their ores, or from compounds containing the same, by the use of a solution of cyanide of potassium or other cyanide or cyanogen compound of the nature aforesaid containing cyanuric acid or a cyanurate, and in the presence of mercury, or of an amalgam of mercury and sodium or potassium.

Process of and Apparatus for extracting Gold from its Ores. . I, John Glenville Murphy, mining engineer, of Middletown, County of Middlesex, State of Connecticut, United States of America, do hereby declare the nature of my invention for " Process of and Apparatus for extracting Gold from its Ores," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — My invention is an improved process of and apparatus for extracting gold from its ores. Gold is found in ores of two kinds, which are known as "free-milling" ores and "refractory" ores. What are called the "refractory" of gold are such as contain gold sparsely disseminated throughout their bulk, mechanically surrounded or enveloped by baser material, or so united with other elements as to form chemical combinations therewith. Such ores, among others, are those which contain galena, zinc-blende, iron-pyrites, white iron (arsenical), and the ores of copper. The free-milling ores have a large percentage of their gold in a finely-divided flake, molecular, or flour state, and much of this flour gold is wasted or lost in the process of milling, either being carried away by the force of the water necessarily used in connection with the stamp-mill, or remaining unreleased from the rock or gangue and being rejected along therewith. The stamp-mill, which can be used only with free-milling ores, is necessarily wasteful of a large percentage of flour gold, and the smelting processes heretofore used in reducing refractory ores are expensive. In other words, ores do not in practice yield the quantities of gold which careful chemical analyses show them to contain, or, if they do, the cost of getting the gold exceeds its value. I have invented a method or process of recovering the gold from all such ores, and an apparatus or arrangement of machinery whereby this process may be made effectual, and my method and apparatus are applicable as well to refractory as to free-milling ores. I have found by actual experiments, and by practical exploitation of my invention, that, so far as the results go, it is immaterial whether the gold in ores such as I have mentioned is united to other elements, chemically, mechanically, or otherwise —the point of my discovery being that the gold may be recovered completely from such ores, and the same thereby rendered of value nearly equal to the absolute amounts of gold they contain, at a comparatively small expense. While it may not be absolutely true that gold is chemically united with baser elements in all of the refractory ores, it would seem to be true that in some of them at least there is a quasichemical union existing between the gold and some one or more of the other elements or combinations of elements. Whatever the real nature of the union may be, the fact is known to all practical mining engineers and chemists that from some ores fairly rich in gold it is impossible to get reasonable returns except at great expense for transportation and smelting, whereby their commercial values are destroyed. I have discovered that all these ores may be profitably milled by reducing the entire body of gold-bearing ore uniformly and completely to an impalpable powder by gentle attrition, and treating this powder for the separation of gold by amalgamation. That extreme comminution or progressive subdivision of a compound substance mechanically will produce chemical change may or may not be true, but it is certain that such extreme comminution renders chemical change more readily possible than it would otherwise be, other things being equal. It is also certain that if the union between elements in any substance is merely a mechanical mixture, a conglomeration, or solution, minute subdivision of such substance may be carried far enough to separate the elements themselves. In all methods, processes, and machines heretofore devised for extracting gold from its freemilling ores there has been one defect which is wasteful of a large percentage of flake, flour, or molecular gold. This defect is written in plain characters upon the face of every apparatus and every process in use at the present day, and the practical novelty and utility of my invention appear as soon as the case is stated.
C.—3
192
Every practical milling method treats the separation and recovery of flake, flour, or molecular gold as subsidiary and as of secondary importance to the treatment of the ore for the separation and recovery of the grosser particles of gold; whereas the only method whereby flake or flour gold can be milled without loss is to make the recovery of gold in this state the main object of the extraction process, and this can only be done by reducing the whole of the gold-bearing ore to a uniform and impalpable powder, comminution being carried to the last possible degree without hardening or hammering the ore during the process. Smelting processes are expensive, but have heretofore been necessary for the reduction of refractory ores, as prior to my invention it was impossible to mill such ores satisfactorily. My process consists, essentially, in reducing the entire body of gold-bearing ore, whether free-milling or refractory, as well the gold or gold compounds therein as the gangue and other materials associated therewith, to a state of such fine pulverisation that there will be no distinction between one particle and another in regard to size— i.e., all the free gold will be in a flour, flake, or molecular condition, and all the other materials will likewise be powdered, the reduction being accomplished without hammering, pounding, or compressive grinding. This reduction to practical uniformity in the minuteness of the particles of the whole mass will predispose to chemical change, and will prepare the mass for new chemical combinations, so that uncombined gold will the more readily be taken up and amalgamate with mercury, and gold in combinations in the minute particles will the more easily leave these combinations to form a new one by amalgamation. In practice I find that ore-powders passing through screens having from one hundred to three hundred meshes to the linear inch are sufficiently fine, but finer states of division may be obtained, and may be necessary with some ores. All gold-ores, with the exception of such as have their gold chemically united to a baser material, contain a percentage of flour or flake gold varying from 30 per cent, to 100 per cent, of the total amount of their gold. Many mines which show assay-values of from $18 to $34 per ton in native gold never produce any such values by practical working, for the simple reason that from 40 per cent, to 70 per cent, of their native gold is in the flour, flake, or molecular condition, and is largely lost or wasted in the methods of extraction now used. Now, the value of my process, its novelty and utility, appear in this : the saving of all, or practically all, of the gold in such ores, thereby rendering them of nearly their gross values, as indicated by chemical analyses, and, furthermore, in rendering possible the milling of refractory ores such as are ordinarily smelted. The process by which I realise these conditions and effect this saving, and the apparatus by means of which I carry out this process, will now be described, describing the one with the other for the sake of brevity. I have illustrated the apparatus in the accompanying drawings, in which like letters of reference indicate corresponding parts, and in which—Figure 1 is a view of the essential portions of the apparatus as seen in vertical section, the figure being in the nature of a diagram ; Figure 2 is a view snowing in detail one of the parts; and Figure 3is a view showing in detail the guards or gratings used to prevent the outflow of large pieces of ore from the cylinder. In the drawings, the letter A indicates an elevator or conveyer arranged to feed broken or crushed ore from any suitable rock-breaker or ore-crusher [not shown] into a hopper B, whence it falls by gravity through the inclined chute b into a pulverising cylinder C. The pulverising cylinder C may be made of any suitable material, and maybe mounted and operated in any convenient manner ; but the arrangement shown in the drawings, and about to be described, is the one I prefer. As shown, this cylinder revolves on hollow trunnions, which open into both its closed ends, and these trunnions run in suitable boxes d d, secured to a supporting-frame D. The cylinder may be strengthened and further supported by rollers arranged beneath it between the trunnions. The trunnion c at the receiving end of the cylinder receives the neck of the chute b within its inner periphery at its outer end, and the joint between the two is made as close as possible in order to prevent waste. The opening in this receiving trunnion is the frustrum of a hollow cone flaring toward the interior of the cylinder, this structure facilitating the delivery of the broken or crushed ore from the hopper into the cylinder, and preventing stoppage or clogging of the ore within the trunnion. The trunnion c 1 at the discharge end of the cylinder is provided with suitable guards or gratings c 2 of iron or steel bars at its inner end, to prevent the outflow of coarse pieces of ore or the like, while the spaces between these bars will allow the comminuted materials to escape as soon as they rise above the middle of the cylinder. This trunnion c 1 has its outer end flared to assist in the outward feed of the pulverised ore. The cylinder is provided with a man-hole c 3, by means of which access may be had to the interior, and has at or near one of its ends the gear-wheel C 1 secured to it, the said wheel meshing with a gear-wheel upon a power-shaft P. In practice I find the best results are obtained from a porcelain-lined cylinder from 8 ft. to 12 ft. in length, having a diameter of from 6 ft. to 8 ft., and I charge this cylinder with about 3 tons of loose Norway flint pebbles or large pieces of ore, ranging in size from 1 in. to 2 in. in diameter. Setting the cylinder in rotation, crushed ore is fed into it by gravity from the hopper B, and as it passes from the receiving end of the cylinder to the discharge end the ore is ground between the porcelain lining and the pebbles and between the pebbles themselves, and the pieces of ore rubbing against each other are gently worn away by self-attrition, the whole operation resembling as closely as possible the natural destruction and wearing-away of rock whereby placer deposits are formed. It is to be noted that the friable materials used as described act by attrition upon the malleable constituents of the ore, wearing and tearing them gently and progressively. It will be seen that no ore will be discharged through the trunnion c 1 until the total mass within the cylinder rises to the level of the said trunnion, and is forced outward by the flow of crushed ore through the trunnion c at the receiving end. While it is true that the cylinder, if revolved at sufficient speed, would cause the crushed ore to pulverise itself without the use of flint pebbles or large pieces of ore, still, experience proves that
193
C.—B
by using these pebbles time and power are economised. The ore is fed continuously into the hopper B, and thence is fed by gravity into the pulverising-cylinder C, where the impact and grinding action of its own particles, combined with that of the pebbles and of the walls of the rapidly-revolving cylinder, reduce the ore to an impalpable powder, without compression of the particles, the fineness of which, before it passes through the discharge end of the cylinder at the trunnion c l , is determined by the number of revolutions made by the cylinder and the length thereof. I find by actual test that under the feed or flow of the ore from the hopper B, the said feed being occasioned by gravity alone, the course of the particles of ore through the cylinder is approximately a spiral, beginning at the feed end of the cylinder and ending at the discharge end, and that by the time the ore has travelled this distance it is sufficiently pulverised for the purposes of my process. It will be obvious that by lengthening the cylinder, or by increasing the rate of revolution, or by prolonging the grinding, other things being equal, the fineness of the ore will be proportionately increased at the discharge end. Comminution maybe had in the cylinder either in the presence of water or dry; but ordinarily the use of water is found to be of advantage. However, practice in each case must determine the particular requirements of each ore-body to be ground—whether it shall be ground wet or dry; and with some ores it may be desirable to use another lining than porcelain for the cylinder. The comminuted ore may be tested to determine its fineness by taking a sample of discharge and passing it through a screen made of silk fibre. Platinum screens may also be used as fine as 200 wires to the linear inch, but for the finer states of comminution silk gauze is the only means of testing. This comminuted ore is discharged into an amalgamating-pan E, which, as will be seen, is of a simple and ordinary construction, but is provided with a cover E l , having an opening for a faucet or the like, and a chute E 2 , arranged at one side, which extends above the pan and embraces the out-periphery of the outer flaring end of the trunnion c l . This arrangement of cover and chute with the flaring trunnion of the pulverising-cylinder prevents waste of the powdered product as it falls into the pan, insures the delivery of such product within the pan, and retains it therein. In using the amalgamating-pan I avoid a flow of water, and merely admit enough water to the pan to moisten the pulverised ore and form a thin paste with it. By avoiding the use of flowing water one cause of waste is eliminated, as it can easily be seen that any flow of water would carry off some of the gold in its finely-divided state. The pan E is provided with mullers c, which may be of any usual or suitable construction and material, and are driven in the usual way by a shaft geared with the power-shaft. There is an inclined well e 2 in the bottom of the pan, which is provided with a plug or tap e s , and the entire contents of the pan may be discharged there from time to time by removing the tap or plug e s and washing the charge into the settler F. From the time the ore leaves the hopper B until the ore, mercury, amalgam, and water are washed into the settler F the fine dust produced is prevented from floating in the air and from being lost thereby, or by reason of draughts, gusts of wind, or the like. The settler F has a stirrer/, which consists of radial arms/ 1 provided with shoes or plows/ 2 , and the whole is driven in any suitable manner, such as by the central shaft/ 8 , which is geared to the power-shaft P. The amalgamation of the pulverised ore is accomplished by allowing a limited amount of water to flow into the pan E—just enough water to form a thin paste with the quantity of ore to be treated —say, from a ton to a ton and a half—and then adding sufficient mercury to amalgamate the gold —say, a tank of 75 lb. The discharge from the cylinder may continue or may be stopped for the time being, but if the discharge is continuous there must be a continuous supply of mercury. The muller is set in rotation at about sixty revolutions per minute, and this rate is continued until the amalgamation of the gold in the ore is completed. By panning a sample the progress of amalgamation can be easily determined. As soon as the amalgamation is completed the speed of the muller is reduced, the plug or tap e s is removed from the orifice of the inclined well e 2 at the bottom of the pan, and water is turned on to wash the whole mass of pulp and amalgam into the settler F. The water which washes the charge from the amalgamating-pan serves also to dilute the pulp and make it sufficiently fluid to enable the mercury and amalgam more readily to settle into the well of the settler, which is shown in the drawings as f i . In this settler the amalgam and mercury are finally cleaned and separated from impurities, which are drawn off through the holes/ 5 in the periphery of the settler, these holes being provided, of course, with plugs/ 6 . After sufficient cleansing by means of the revolution of the stirfer-arms and the settling of the mercury and amalgam into the well/ 4 , the mercury and amalgam are finally withdrawn through the said well, or through its orifice, which is provided with a plug or similar device f 7 . The mercury and amalgam withdrawn from the settler are treated in the ordinary way for the recovery of the gold and the saving of the quicksilver. It is to be understood that several amalgamating-pans and several settlers or washers may be used in connection with the pulveriser, either in series or otherwise, as may be most convenient and effective; but I find that ordinarily, with the minute and hardened pulverisation of the ore which I effect, two pans and one settler are ample in the treatment of the product, as amalgamation with pulverised and unhardened ores is rapid. My process has been used in the treatment of telluride ores, and resulted in extracting therefrom between 25 and 33 per cent, of the entire amount of gold therein. My process contemplates a practically continuous operation, the ore being fed forward from the hopper through the pulverising-cylinder into the amalgamating-pan, where it is treated with mercury, and from the amalgamating-pan the whole mass is washed into the settler, where the amalgam and mercury are cleaned and separated from the rest of the mass; and each and every step in this feeding-forward is accomplished by gravity alone. While this is apparent enough in
C—3

the other portions of the process from the construction of the apparatus, it might seem to need some explanation as applied to the comminuting-cylinder; but when it is considered that there is a continuous pressure at the receiving end of the cylinder, caused by the inflow of the crushed ore, and that this ore from the time it is received within the cylinder is ground and pulverised in a progressive way until the particles are separated one from another to almost the last degree, it will be seen that the pulverised dust or flour thereby produced, being in continual agitation, caused by the revolution of the cylinder and the motion of the pebbles therein, will be approximately analagous to a fluid, and subject to the law of equal pressure in all directions at the same level. This holds true whether the ore be ground wet or dry. Now, the inflow being at one end, and the only possible outflow at the opposite end, and the inflow arising from gravity alone, it follows that the outflow necessarily arises from gravity. It is of importance to note that pounded or hammered gold will resist the action of mercury for a long time, and that the so-called "rusty " gold is merely gold enveloped in a coating of some substance—a gas, a film of grease, a deposit of iron rust, or the like — and thereby protected from the action of mercury. Now, before gold that has been hammered will amalgamate readily with mercury it must be annealed, and before rusty gold can be amalgamated the coating surrounding the gold must be pierced or removed. Further, the resistance of hammered gold to amalgamation with mercury is irrespective of mass--or, in other words, equal surfaces of gold hammered to equal degrees resist amalgamation equally, and the size and shape of the hammered particles are relatively unimportant, their total surface areas being the real things for comparison. Likewise, gold which is rusty, whether in a large mass or in a small particle, is protected from mercury as long as its envelope remains entire. Stamp-mills, ore-crushers, and the like have a hammering or consolidating effect upon gold subjected to their action, and while much of their flour or powdered gold is probably lost through waste from the great force of water used in connection with them, another large percentage of the total waste is undoubtedly due to the fact that such gold as is not lost in the first instance is lost in the latter processes by reason of its hammered condition and its consequent slowness to amalgamate with mercury. Now, the difference between the product obtained by my process and the products resulting from the processes formerly in use consists not only in the greater fineness in the reduction practised by me, but principally in the fact that this comminuted product is unhammered, uncondensed, unhardened, and also in the fact that the rusty gold is not only deprived of its coating, but that this is done without compressive grinding, and in such a way as to leave the gold in its natural and soft condition. The pulverisation effected by my process is not only an extreme comminution of the total mass of the ore body, but it is such a comminution obtained without the tremendous pounding or compressive grinding actions used in other processes. While it is true that the crushed ore delivered into the pulverising-cylinder will have been subjected to some little grinding, pounding, or compressing in the rock-breaker or ore-crusher necessarily used for breaking it, it will be seen that this compression will be effective upon a very small portion of the mass, and that within the cylinder the pulverisation is accomplished more by attrition, wearing, gentle grinding, and the like than it is by a pounding action, a compressive action, or a hammering process. In other words, comminution is effected without condensation, hammering, or compression of the gold, and the powdered product is delivered into the amalgamating-pan not only in the finest possible condition— i.e., in the condition presenting the greatest surface-area for a given quantity of gold—but the surfaces of the particles making up this greatest area are worn and scratched in such manner as to present the metal most effectively to the action of the mercury and the gold itself in its natural and soft condition. It may be noted in this connection that some degree of heat is produced in the pulverising-cylinder, though this rarely rises above 150° Fahr., and, while this would not be sufficient under ordinary circumstances to cure hammered gold, it may have some effect in preparing the infinitesimal particles produced by my process for amalgamation, especially by driving out of the pores of the gold gases, greases, and the like. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is,— 1. In an apparatus for separating gold from its ores, the combination with a pulverisingcylinder, revolving on hollow trunnions both flared in the same direction, of a hopper having an inclined chute fitting within the inner periphery of the outer end of one trunnion, and a covered amalgamating-pan having an inclined chute embracing the outer periphery of the outer flaring end of the other trunnion, substantially as and for the purpose set forth. 2. The process of separating gold from its ores which consists essentially in reducing, without compressive grinding, hammering, pounding, or the like, the entire mass of ore equally to an impalpable powder by gentle attrition of the mass in a gradually-fed revolving cylinder, whence only the thoroughly pulverised materials are permitted to escape by overflow as an impalpable powder, delivering said powder to mercury in an amalgainating-pan to which water is admitted only in quantity sufficient to form a paste, and not enough to produce a flow of the pulp ; and finally, when the amalgamating action upon the ore has been completed, washing the pulp into a settler where the amalgam settles from the diluted mass while the impurities are drawn off. 3. The process of separating gold from its ores which consists essentially in reducing the ores to an impalpable powder by gentle attrition in a revolving cylinder, from which only the thoroughly pulverised materials are permitted to escape by overflow into an amalgamating-pan, amalgamating the pulverised materials within the said pan with a quantity of water neither increased nor diminished during the process of amalgamation ; and, finally, when the amalgamating action upon the ore has been completed, washing and diluting the pulp into a settler where the amalgam and impurities are separated.

An Improved Process for the Treatment of Zinciferous Ores. I, Ernest Frederick Turner, of the Adelaide University, Adelaide, in the Province of South Australia, analytical chemist, do hereby declare the nature of my invention for "An Improved Process for the Treatment of Zinciferous Ores," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — My invention relates to an improved process for the treatment of zinciferous ores, and more particularly that class of ores which contains also gold, platinum, silver, or lead. The object of my invention is to remove the zinc from the ore, subsequently recovering the same in metallic form, and afterwards treating the ore-stuff for recovery of the lead and other metals contained therein. In my invention, the ore in a suitable state of division is roasted or otherwise heated at a high temperature, either above or after being previously mixed with carbon. During the roasting or heating operation a stream of superheated steam is passed through the roaster or otherwise brought in contact with the ore under treatment. By this means the ore is oxidized and H 2 S given off where the ore is being treated alone, or H 2 S with hydrogen, and CO where carbon has previously been mixed with the ore. The gas so given off is collected in a suitable gasometer for use as fuel, and the products of combustion returned for treatment of the oxidized ore in the following manner: The oxidized ore, accompanied by water containing salt, is caused to fall through a suitable tower, through which at the same time a stream of S0 2 , obtained as previously indicated, is constantly ascending. By this means the whole of the ZnO is converted into ZnS0 3 (zinc-sulphite), which is later removed from the ore by lixiviation, together with any copper which may be present. At the same time, by the action of the S0 2 , the oxide of lead is partially converted into sulphite of lead, and the silver-sulphite into silver-chloride. The liquor from the zinc lixiviating-vats is passed over copper, to remove any silver which may be in solution, and afterwards through zinc turnings for the recovery of any copper and lead. The liquor is then passed through towers through which H 2 S, obtained as previously indicated, is passing, and thereby the zinc contained therein is precipitated as sulphide together with sulphur. The ore-stuff remaining in the lixiviating-tanks after the liquor containing the zinc has been drawn off is then heated, whereby the sulphite of lead breaks up into sulphide of lead and sulphate of lead, and the two being in contact with any oxide of lead which is still undecomposed in the first operation by the action of S0 2 soft metallic lead is produced. Or, if the ore-stuff contains silver, it is mixed with zinc-chloride, either alone or with the addition of metallic zinc or other suitable metal, and then heated for the obtaining of the lead as soft metallic lead. The chlorides of silver, gold, and other metals will then still remain with the zinc-chloride, and can be separated therefrom by lixiviation or by any other suitable means. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. In the treatment of zinciferous ores, the herein-described process, consisting in, first, oxidizing the ore in a suitable roaster, then causing the oxidized ore, accompanied by water containing salt, to be acted upon by a stream of S0 2 , whereby the whole of the oxide of zinc is converted into sulphite of zinc and hypo-sulphite of zinc, the oxide of lead into sulphite of lead, and the sulphite of silver (if any) into chloride of silver ; subsequently extracting the sulphite of zinc by lixiviation, and treating the liquor by H 2 S, whereby the zinc-sulphites are precipitated as sulphides ; subsequently removing the same ; and treating by any known process; at the same time taking the ore-stuff remaining after the liquor has been drawn off containing the sulphites of zinc, subsequently heating the same, either alone or with zinc-chloride alone, or with zinc-chloride and metallic zinc, or other suitable metal, whereby the sulphite of lead breaks up into sulphide of lead and sulphate of lead, and soft metallic lead is produced, the chloride of silver being subsequently separated from the zinc-chloride by lixiviation or any other suitable method. 2. In the treatment of zinciferous ores, the herein-described process, consisting in, first, oxidizing the ore in a suitable roaster, then causing the oxidized ore, accompanied by water containing salt, to be acted upon by a stream of S0 2 , whereby the whole of the oxide of zinc is converted into sulphite of zinc and hypo-sulphite of zinc, subsequently extracting the sulphite and hypo-sulphite of zinc by lixiviation, and treating the liquor containing the same by H 2 S, whereby the zinc-sulphites are precipitated as sulphide; subsequently recovering the same in metallic form by any known process. 3. In the treatment of zinciferous ores, the within-described process, consisting of, first, roasting the ore, then converting the oxide of lead into sulphite of lead, and the silver-sulphite into silver-chloride, preferably by the action of S0 2 or other known process; subsequently taking the ore-stuff remaining after the removal of the zinc by lixiviation and heating the same, either alone or with zinc-chloride alone, or with zinc-chloride and metallic zinc, or other suitable metal, whereby the sulphite of lead breaks up into sulphide of lead and sulphate of lead, and soft metallic lead is produced, the chloride of silver and other precious metals being subsequently separated from the zinc-chloride by lixiviation or any other suitable method. Dated this 21st day of July, 1896. E. F. Turner.
An Improved Dredge. . I, George Poll, of 54, Lambton Quay, in the City of Wellington, in the Colony of New Zealand, miner, do hereby declare the nature of my invention for " An Improved Dredge," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — The object of my invention is to provide a dredge for use in harbours, rivers, and the like, for raising mud or other detritus, or gold-bearing deposits, which dredge shall lift the material to be raised in a more economical and effective manner than with dredges as at present constructed. 26—C. 3.

I carry the object of my invention into effect by making a hull somewhat similar to those at present in use, but I construct therein a well passing through the hull. Above this well I erect a staging which supports guide-rods extending above and below the hull. Suitable guys steady and support the guide-rods, and the depth of the same may be varied to suit the depth at which it is required to work. The guide-rods are connected together at their ends, and stiffened by cross-rods. The bucket is secured to a vertical and hollow shaft, and revolves with the same within brackets provided with friction-wheels, which are flanged to roll upon the aforesaid guide-rods. The bucket is made cylindrical in shape, and has its bottom provided with hinged flaps which may fall down to form a cutting edge, and with a screw-like action may scoop up material into the bucket. When the bucket is loaded, the flaps are closed by means of a shaft which passes down to the bucket through the hollow shaft before mentioned. A crank handle is used at the top of this inner shaft to revolve the same, and by means of a screw-thread formed upon the lower extremity, the said shaft engages with a nut and links which are connected to the flaps. This said nut is of peculiar construction, being made in two halves, which may be held to their work by a strap, but when this strap is lowered the two halves of the nut will separate under the action of suitable springs and thus be disengaged from the shaft. The flaps being closed, the bucket is raised by means of a chain passing to a winch over a pulley attached to the staging, when the nut is liberated and the material allowed to fall through the flaps at the bottom of the bucket into a chute, and over the side of the vessel into an ordinary punt. The bucket is revolved by means of a chain passing from the winch to a pulley, and bevel wheels, connected to the upper end of the hollow shaft. In order that my invention may be most easily understood, I will now proceed to describe the same in detail, and shall for that purpose refer to the accompanying drawings, whereon Figure 1 is a side-elevation of my dredge showing the bucket lowered. Figure 2is a plan of the same. Figure 3is a vertical section of the bucket with its bracket. Figure 4is a vertical elevation of the same. Figure sis a plan of the same. Figure 6is a side-view of the bevel gearing, and bracket. Figure 7 is a plan of the same. Figure Bis a side-view of the nut and attachments. Figure 9is a plan of the same. Figure 10 is a side-view of the same. Figure 11 is a side-view of a square driving-shaft and spur gearing. Figure 12 is a view of a spliced shaft. Referring to these views, ais the hull, having a well a l , and a staging a 2, which supports the guide-rods b; ordinary railway rails are admirably suitable for making these rods b. Guys b l steady and support the guide-rods above and below the hull. The weight of the rods is taken upon chain 6 2 , one of which is provided on each side, and being secured to the bottom of the rods, pass over pulleys & 3 , which are secured to the staging a 2, and thence to the winch cby means of pulleys b*. When being raised by means of these pulleys and ropes, the rods b slide within brackets a 3 , Figure 5, fixed to the staging. The bucket d is secured to shaft d l , and revolves with the same, within brackets a" 2 , and J ls provided with friction-wheels d 3, which roll upon guide-rods b. The shape of the bucket is cylindrical, but its bottom is formed as shown in Figures 1, 3, and 4, and is provided with hinged flaps d l , which, when let down and revolving in the direction shown by the arrow on Figure 5, cut into the material to be lifted and raise it into the bucket. As the material rises upon the flaps it is guided by guard plate d e on to the fixed portion cV of the bottom of the bucket, and into the interior of the same. When the bucket is loaded, the flaps are closed by turning the crank-handle d b , which will revolve shaft/, and draw up nut f 1 and links/ 2 , which are connected to the flaps. Nut f 1 is of special construction, as may be seen by reference to Figures 8, 9, and 10, where it is shown on a large scale. The nut proper is made in two halves f l , screw-threaded on the inside, and having a wedge shape on the outside. The nut fits freely within a framing/ 10 , and springs/ 3 tend to separate the two halves of the nut and disengage them from the screw-thread of the shaft/ A strap/* passes around the nut, and when forced up the wedge-shaped faces force the halves of the nut into position upon the shaft. The strap is held in place by an eye-bolt/ 9 , which is hinged to the strap by pin/ 5 . Nuts/ 6 rest upon a bracket/ 7 secured to frame/ 10 , and a pin/ 8 prevents the eye-bolt from disengaging. As the various parts wear, the nuts/ 0 may be correspondingly adjusted. Flaps d l being closed, the bucket is raised by means of wire-rope or chain g attached to bucket bracket d?, and passing over pulley gto winch c. Strap fis then released to liberate the two halves of the nut f 1 and allow the flaps d i to fall. The material will fall through chute h into an ordinary punt. The bucket is revolved by means of a chain J, passing from the winch by guide-pulleys J 1 to pulley J 2 . A bevel-wheel J 3 is secured to pulley J 2 , and gears with a large bevel-wheel J 4 , which is secured to the upper end of hollow shaft a l . Pulley J 2 and wheel J 3 are carried upon a bracket J 6 , built up upon bracket J 6 , which carries the upper end of hollow shaft d\ To raise the bucket, chain J is lifted off pulley J 2 , when the bucket, shafts, d 1 and /, and brackets d 2 and J 6 , will be free to rise bodily. On Figure 11 I have shown a spur-wheel Kin place of the large bevel-wheel J 4 , and a pinion K 1 in place of the small bevel-wheel J B , and a square vertical shaft K 2 in place of chain J. By this arrangement the necessity of removing the chain J in order to lift the bucket is obviated, as the shaft is driven by any suitable motor, gearing with spur-wheel X", which being secured to the shaft near the deck, may revolve within a bracket K 4 , and pinion K 1 may slide upon the shaft K 2 whilst it is free to revolve within its bracket K 5 carried upon bracket J 6 . The upper end of the shaft may be pivoted at X" to revolve in any suitable bearing K 7 bolted to the staging a 2. It is obvious that I may use a circular shaft in place of the square one, and groove the same to engage with a feather secured in the pinion K l . Shafts dr and / may be spliced to suit the depth to be dredged, and for this purpose I provide couplings I, consisting of flanges secured to sections of the shaft d l , and bolted together by bolts

I wish it to be understood that I do not confine myself to the exact details hereinbefore set forth, as these may be modified in several ways without departing from the spirit of my invention. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. A dredge constructed with a well through which guide-rods may pass to support a bucket, substantially as and for the purposes set forth herein. 2. A dredge constructed with a well through which guide-rods may pass to support a bucket revolved by a chain and bevel-wheels, substantially as and for the purposes set forth herein. 3.

An Improved Machine for Concentrating and Amalgamating the Precious Metals. I, John Robinson, of Coromandel, Auckland, in the Colony of New Zealand, mine-manager, do hereby declare the nature of my invention for " An Improved Machine for Concentrating and Amalgamating the Precious Metals," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — The object of my invention is to provide an apparatus by which the operations of amalgamating and concentrating the precious metals after the ore has been crushed may be performed with greater facility and with less expenditure of power, and at the same time that the machinery is much more simple and more easily maintained and repaired. In carrying my invention into effect I make use of a circular pan, having an inner and outer channel constructed at the periphery of the said pan and concentric with one another, and I divide this circular pan into two halves or semicircles, between which semicircles I fix a powerful arm, and to which I give a reciprocating motion by any suitable power, the pan itself having a central axis upon which it oscillates. The reciprocal motion I prefer to communicate by means of a shaft revolving in suitable bearings, upon which shaft is formed a zigzag groove, into which zigzag the end of the oscillating lever, or a roller attached to the same, is fitted, and makes one oscillation to the revolution of each zigzag. Each half of the inner circle is fed with material from the battery or crushing-mill. Openings connect the inner and outer semicircles or channels, so that the material flows from the inner to the outer semicircle by the centrifugal force produced by the oscillating motion. In each of the outer semicircles are two orifices fitted with regulating valves, one for the discharge of the water and tailings, and one for the pyrites. In order that my invention may be more easily understood I have illustrated the same upon the accompanying drawings, whereon similar letters and figures of reference indicate like parts : Figure lis a plan of my apparatus. Figure 2is an elevation of the same. Figure 3is an elevation of the discharge ports in the outer circle. Figure 4is an elevation of the ports in the inner circle. Referring to the views, A is the outer channel or circle and B the inner channel or circle, which channels are divided at C into two halves or semicircles, and between these semicircles I fix a powerful arm D. The pan has an axis E, upon which it oscillates, and reciprocal motion is imparted to arm D and the pan by any simple motive-power, but preferably by a cam F, having a zigzag groove F l , and mounted upon driving shaft G, revolving in suitable bearings G l . A roller D 1 is attached to arm D to reduce friction and give ease of movement. Material from the battery or crushing-mill is fed through chutes J into each half of the inner circle B, into which a quantity of quicksilver has been placed. Openings or ports X connect the inner and outer semicircles or channels through which the material flows by the centrifugal force produced by the oscillating motion of the pan, or by the inflow of fresh material. In each of the outer circles are two openings or ports : the one, M, forming an overflow for the tailings, and N a discharge into the concentrating-tank. These openings may be provided with valves to regulate the flow. It will be seen that material may be brought from a battery down one of chutes J and material from another battery down the other chute, and thus the returns from such batteries may be kept separate; that, as the pan is made in two halves, it is portable; and that the outer circle or channel will save heavy minerals and may be adjusted to concentrate as required. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,—.

Improvements in Mechanical Ore-separators. I, John Wendell Carter, of Brooklyn, in the County of Kings, and State of New York, U.S.A., gentleman, do hereby declare the nature of my invention for " Improvements in Mechanical Oreseparators," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — This invention has reference to certain improvements in that class of machines which are known as magnetic ore-separators, in which a number of permanent magnets are arranged in gangs one below the other, and over which the ground ore is passed by gravity, so that the magnetic particles of ore are separated from the non-magnetic particles in a quick and reliable manner. The invention consists of an ore-separator in which a series of permanent magnets is arranged below the supply-hopper in such a manner that the lower pole ends are receding below the upper pole ends, which latter are in the path of the falling material that is conducted from the hopper over a magnetic deflecting-plate that is arranged above and at a short distance back of the upper pole ends of the magnets; so that the magnetic ore-particles are separated from the non-magnetic particles in their passage over the deflecting-plate and upper pole ends, and gradually conducted to the lower pole ends, while the non-magnetic particles are dropped by gravity and collected in a separate receptacle from the magnetic particles. The invention consists, further, of certain details of invention which will be fully described and finally pointed out in the claims. In the accompanying drawings, Figure 1 represents a side elevation of my improved magnetic ore-separator, showing the same arranged with three gangs of stationary magnets one below the other; Figure 2 is a front elevation of the same; Figures 3 and 4 are detailed vertical sections drawn on a larger scale, showing two different arrangements of the stationary magnets; and Figure 5 is a side elevation, partly in vertical section, of one gang of magnets and its supplyhopper, drawn on a still larger scale. Similar letters of reference indicate corresponding parts. Referring to the drawings, A represents the frame of my improved ore-separating machine, on the top of which is arranged a supply-hopper B, into which ground ore is placed. From the supplyhopper B the ore passes into a second hopper C, that is arranged vertically below the supply-hopper B. The hopper Cis attached by means of slotted angle-bars d, and screws d 1 to the supported frame A, the angle-bars being attached to the side walls of the hopper C and the side posts of the frame A, as shown clearly in Figures 1 and 5. Below the hopper C are arranged two series or rows of permanent magnets D, which together form a gang. The magnets D are supported in boxes D l , of wood or other non-magnetic material, which are guided in exterior frames D 2 that.are connected by pivots d 2 at their front ends to the posts of the supporting frame. The rear ends of the supporting frames D 2 are supported by hanger-rods H, which are provided with turn-buckles H\ said hanger-rods being suspended by means of eyes at their upper ends from horizontal cross-rods X of the supporting frame A. By means of the turnbuckles the suspending-rods H can be lengthened or shortened, so as to give to the magnet-holding frames D 2 and to the rows of permanent magnets in the same the desired degree of inclination. The boxes D in which the magnets are located are connected with the rear parts of the frames D 2 by means of screws m, so that the boxes can be adjusted longitudinally in the frames D 2, said boxes being guided in ways or other suitable manner on said frames. By the adjustment of the adjustable frames and boxes one series or row of magnets D can be so arranged relatively to the other that their pole ends are arranged in the incline plane, so that the upper pole ends of one row of magnets extend beyond the lower pole ends of the same —in other words, that the lower pole ends are located in vertical planes to the rear of the upper pole ends, as shown in Figure 3 ; or the pole ends of the upper series of magnets may be arranged to project over the pole ends of the lower series of magnets, so that the latter are located in vertical planes successively to the rear of those above, as shown in Figure 4. On the top of the upper magnet-holding box D lof each gang of permanent magnets is arranged an inclined magnetic deflecting-plate E, which is located near the front edge of the box, and adapted to be adjusted on the same in any approved manner. Below the lower series of magnets of each gang is arranged a chute F, the upper edge of which is vertically below the edge of the upper pole ends of the upper row of magnets, so that the magnetic ore-particles that are dropped from the pole ends are collected and conducted over a second chute F 1 to a suitable collecting receptacle. At the inside of the inclined front wall of the hopper C is arranged a deflecting-plate c, which is retained by a headed pin e 1 at its upper end, and adapted to be adjusted by means of a set-screw e 2 that passes through the inclined front wall of the hopper C, so that the inclination of the deflecting-plate can be adjusted, and thereby the stream of ground-ore thrown from the hopper to a greater or less distance, according to the relative position of the deflecting-plate E from the upper pole ends of the magnets. The parts so far described constitute one gang, and are repeated in each gang, of which a plurality may be arranged one below the other, all being supported by the

frame A, as shown clearly in Figures 1 and 2. The operation of my magnetic ore-separator is as follows: The ground ore to be separated is conducted from the supply-hopper B into the uppermost hopper C, and from the same on to the deflecting-plate E, which is of magnetic material, and to some extent under the magnetic influence of the upper series of magnets. From the deflectingplate E the ground ore passes over the edge of the supporting-box D lon to the upper pole ends of the upper series of magnets. While the mass of ground ore passes over the deflecting-plate E, the magnetic ore-particles are brought within the influence of the magnets, and are slightly retarded in their motion, while the non-magnetic particles continue in their motion. The influence of the pole ends on the magnetic particles, and consequently the retardation of the latter, increases as they approach the upper pole ends of the upper series of magnets, while the non-magnetic particles, being not subject to magnetic attraction, are thrown forward with considerable velocity, so as to fall beyond the chute F and drop into the hopper C of the second gang of magnets. The magnetic ore-particles accumulate on the upper pole ends of the upper series of magnets, pass gradually from the same to the lower pole ends of the upper series, and. from the same to the upper pole ends of the lower series of magnets, and then to the lower pole ends of the same. The magnetic particles accumulate gradually to such an extent as to form a continuons web or fleece-like body, which gradually permits the outermost particles to become loose, and move down by friction over the web or fleece until they are dropped on the chute F, and passed over the same into the collecting receptacle. The particles taken up by the hopper C contain still a small quantity of magnetic particles. They are passed succcessively in the same manner over the pole ends of the lower gang until the entire separation of the magnetic particles from the non-magnetic is accomplished. In Figures 3 and 4 the motion of the magnetic ore-particles from pole end to pole end is represented, the magnetic ore-particles being attracted around the pole ends until a sufficient quantity is accumulated, and the magnetic influence of the pole end overcome, so that they slide downwards towards the next lower pole end, where they again accumulate, filling up the space between the pole ends and passing on to the next pole end, and so on, until they are dropped on to the chute, and conducted off. The action of the pole ends of the magnets of the lower gang on the magnetic particles that are delivered by the hopper of the second, third, &c, gang, is the same as in the first gang, all the magnets being charged, so to say, with an armature of accumulated ore-particles, whereby the remnant magnetism of the same is retained, and the very effective separation of the ore from the gauge produced without any change in the trajectory of the falling material, which continues to drop according to the law of gravity. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The combination, with a supply-hopper, of a series of permanent magnets, the pole ends of which are located below the hopper, and an adjustable deflecting-plate located above and at a short distance back of the pole ends of said magnets, and in the path of the falling material, substantially as set forth. 2. In a magnetic ore-separator, the combination of a supply-hopper, a series of magnets having the extreme attractive or active surfaces of their uppermost poles directly in the path of discharge of the ore-particles and the attractive or active surfaces of the poles beneath out of said path, but directly in the path of that portion of the magnetic material that has been separated by said uppermost poles, and an inclined magnetic deflecting-plate located below the mouth of the hopper, and arranged above but out of contact with the attractive or active surfaces of said uppermost poles, substantially as set forth. 3. In a magnetic ore-separator, the combination of a supply-hopper for the ore-particles, two series of magnets placed one beneath the other and having the extreme attractive or active surfaces of the poles of the upper series of magnets directly in the path of discharge of the ore-particles from the supply-hopper, so as to be in direct contact with the ore-particles to be treated, and having the attractive or active surfaces of the poles of the lower series of magnets at some distance back from and out of the path of the ore-particles to be separated, but directly in the path of and in direct contact with that portion of the magnetic material that has been separated by the poles of the upper series, and an inclined magnetic deflecting-plate located below the mouth of the hopper, and arranged above and out of contact with the poles of the upper series of magnets, substantially as set forth. 4. In a magnetic ore - separator, the combination, with a supply-hopper, of a series of permanent magnets located below the hopper, a box for supporting said magnets, a pivoted frame for guiding said box, means for adjusting the box on said frame, and means for adjusting the inclination of said frame, substantially as set forth.

An Improved Machine for Breaking or Crushing Ore, Rock, and the Like. I, William Ernest Hughes, of 42, Lambton Quay, Wellington, New Zealand, registered patent agent, do hereby declare the nature of my invention for " An Improved Machine for Breaking or Orushing Ore, Rock, and the like," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — This invention relates to a machine for breaking or crushing ore, rock, and the like, and to that class of such machine in which an oscillating jaw is employed, the object of my said invention being to construct the machine in such a manner that a continuous or constant crushing shall take place, and to improve the construction of the machine so as to permit of the wearing-parts being readily replaced,

According to this invention a double movable jaw is provided, working in conjunction with two rigid crushing-surfaces, the said double jaw being suspended in such a manner that when it is being moved towards one crushing-surface the material is dropping down between the other face of the jaw and the corresponding crushing-surface, whereby a continuous crushing is maintained. The ends having the rigid crushing-surfaces are preferably formed in a single casting with the sides-of the framing, so that the double crushing-jaw swings in a rectangular chamber open at the top and bottom to permit of the introduction of the material to be crushed and of the crushed material dropping out. Motion is imparted to the double jaw by means of a shaft having an eccentric portion upon it and working within a block located in a recess in the lower part of the pendulous double jaw, the bearings of the shaft in the sides of the framing and the block itself in the said recess being arranged in such a manner that they can be readily removed for repairs or renewal. The machine may be driven either directly by means of pulleys upon the main shaft or through the medium of gearing. The crushing-surfaces both of the fixed jaws and the movable double jaw are made detachable, so that they can be readily renewed. To enable my invention to be fully understood, I will describe the same by reference to the accompanying drawings: in which Fig. lis a plan of a machine for breaking or crushing ore, rock, and the like, constructed according to my invention. Fig. 2is a view half in end elevation and half in transverse section. Fig. 3is a view half in side elevation and half in longitudinal section.

The rigid crushing-surfaces b b are arranged in recesses in the ends c c of the framing, as clearly shown in Figures 1, 3, and 8, so that they can be easily lifted out and replaced by new ones when required, and they are secured in position by means of wedges a l , a 1 dropped into recesses on the sides of the framing. With a like object the crushing surfaces b 1 b 1 of the pendulous double jaw are arranged in pairs dowelled together as at b 2 in recesses in the said jaw, as shown in Figure 3, and they are also secured by means of wedges c 1 and bolts m. The hearings n n of the pivot or fulcrum c are made removable, as shown in Figures 2 and 5, to allow of repairs or renewal. The bearings o o of the eccentric shaft g for a like purpose are simply slid into recesses in the framing, as shown in Figure 2, and then secured by studs 01.o 1 . The driving-pulleys I I are in turn secured upon the shaft g by means of pins p p passing through the bosses q q of the pulleys and through collars r r formed in halves and keyed to the shaft, and clamped together by means of bolts s, as clearly shown in Figures 2 and 7. From the foregoing description it will be understood that the shaft g being revolved by either or both of the pulleys I thereon, an oscillating motion will be imparted to the pendulous double jaw aa. So that whilst the ore, rock, or the like material, fed between the fixed and movable crushing-surfaces b b b 1 b 1 is being crushed by the swing of the movable jaw to one side of the machine the said material is dropping down at the other side of the machine in position to be crushed, by the following swing of the jaw towards that side, and so on; the crushing of the material being therefore practically continuous instead of intermittent as heretofore. Having now particularly described and ascertained the nature of my said invention, and in what matter the same is to be performed, I declare that what I claim is, — 1. A machine for breaking or crushing ore, rock, and the like, having a double pendulous movable jaw, working in conjunction with two rigid crushing-surfaces in such a manner that while one face of the jaw is moving towards its corresponding crushing-surface the other face is receding from its crushing-surface so as to allow the material to drop down into position to be crushed at the following swing of the pendulous double jaw, and so on, substantially as hereinbefore described. 2. The machines for breaking or crushing ore, rock, and the like, the combination with a pendulous double movable jaw, of fixed crushing-surfaces, arranged in recesses in the ends of the frame of the machine, and wedges adapted to enter other recesses in the said framing for securing the said crushing-surfaces, substantially as and for the purpose hereinbefore described, and as illustrated in the accompanying drawings. 3. In machines for breaking or crushing ore, rock, and the like, the combination with a pendulous double movable jaw working in conjunction with fixed crushing-surfaces of a drivingshaft, an eccentric thereon, a block in which the said eccentric revolves, and a lined recess in the pendulous double jaw in which the block moves in order to impart motion to the pendulous double jaw, substantially as hereinbefore described, and illustrated in the accompanying drawings. 4. In a machine for breaking or crushing ore, rock, and the like, the combination with a pendulous movable jaw working in conjunction with fixed crushing-surfaces, a driving-shaft, an eccentric thereon, and a block working in a recess in the said pendulous jaw, of bearings for the

Improvements in Pulverising-mills. I, Ammi Vining Young, of the Dom Hotel, Koln, in the Empire of Germany, engineer, do hereby declare the nature of my invention for "Improvements in Pulverising-mills," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — This invention relates to machines for pulverising ores or other hard substances. In the accompanying drawing Figure 1 is a vertical section through the entire mill, Figure 2 a section through the upper part of the machine, and Figure 3 a plan of part of the same. In the upper part of the mill is arranged a pulley I, running horizontally, and driven by a belt by steam or other convenient power. From this pulley is suspended a shaft h by means of a universal joint, and to the lower extremity of this shaft is rigidly secured the crushing-roll c, which is thus free to swing in any direction. In the drawing, a is the base or pan, containing a ring or die b, against which the crushing-roll c works, and upon the inner vertical surface of which the pulverising is done. This pan has a number of openings d through it downward outside the ring or die, which lead into a pit or receptacle c below. Upon the base is secured the screen-frame/, which is surrounded with a sheet-iron cover, to the top of which is fastened a conical shield g, open at the apex, through which the shaft h works. The pulverising-roll c is attached to the lower end of the shaft h, and just above the roll is the fan i, which is used when the mill is crushing dry, but not when crushing wet. On the underside of the crushing roll c are shown stirrers k, which are used in both. The shape of these stirrers is varied according to the nature of the work to be done. The driving-pulley I revolves upon the tapered and adjustable bearing m, Figure 2, which is in turn supported by the frame composed of standards n, Figure 1. Two of these standards are extended above the pulleys to carry an arm 0, in which is secured the hollow journal-pin p. Within the pulley I (the outer part of which is made of wood) is the universal joint from which the shaft his suspended, as shown in Figure 2. This joint is composed of the ball or sphere v, with trunnions s s attached thereto. These trunnions work in half-boxes, which slide up and down in recesses t t, Figure 3, in the pulley-head casting v. The joint in the pulley is enclosed by means of the cover v, thus keeping the working-parts away from all dust and grit. The lubricating-oil is supplied for all parts needing it through the hollow pin p. When the mill is started the pulley and the shaft revolve together, the roll c hanging free in the centre of the ring b ; but if the shaft is pushed outward the crushing-roll con its lower end comes in contact with the ring or die b, and immediately begins to travel round on its inner surface, pressing against it with a force sufficient to effectually pulverise anything that comes in its way. When a quantity of the material to be reduced has been fed into the mill sufficient to fill the pan a as high as the stirrers k on the lower side of the crushing-roll c they work in it, stir it up, and throw it against the ring b, so that it is acted upon by the crushing-roll c, and when fairly in operation the whole body of loose material whirls round rapidly within the pan, and, being brought between the roll and die, is crushed, and all that is sufficiently fine passes at once through the screen w above the die, the coarser portion falling down to be acted upon again. The universal joint by which the shaft is connected with the pulley allows perfect freedom of movement to the roll, so that it can easily pass over obstructions of any kind without damage. It, with its adjoining parts, is constructed as shown in Figure 2. The ball V is carried in a spherical step x upon the body v of the pulley, the lower part of which is formed with an internal cone y, which fits upon a corresponding cone z (with the intervention of an anti-friction lining), the latter being formed with a turned-up flange at its lower end, which is screwed inside so as to be screwed upon the externally-screwed cylinder A, the upper part of which is screwed into the ring B (which is preferably split at one side to give it elasticity), a flange upon the upper end of which is carried by the upper ends of the standards n of the machine. The lower end of the inner conical bearing is provided with bosses C, into which are screwed setscrews (with lock-nuts) which press against the lower end of the cylinder A, and hold the bearing firmly in its place when it has been properly adjusted. Thrust-rings of steel and of anti-friction composition alternately are inserted under the lower end of the hollow revolving internal cone V, to reduce the friction of the latter. The upper part of the hollow body U of the pulley is closed by the cover V, and a steel ring D is fitted upon the upper part of the ball V, and is kept pressed against it by a spring E inserted between the ring and the cover. Upon the upper part of the cover V is formed a set of hollow cone speed-pulleys F, the central bore of which turns, with the intervention of an anti-friction lining, upon the pin P, which is firmly fixed into a strong bracket G, carried by a bracket o upon a prolongation of the standard n. The pin p is hollow, and is provided with channels for lubrication. A second light bracket H, carried by the bracket o, has at its outer end a bearing in which revolves the upper end of a vertical feedingspindle /, which carries cone-pulleys X, driven at the required speed by a cord from the pulleys F already described. Lis a hopper, from which the material to be pulverised is fed uniformly" into
C.—l
202
the mill by means of a feeding-screw M revolving in a chamber connected with the hopper, its axle turning in a bearing carried by the hopper-support, and having fixed upon it a bevelled-toothed wheel N, gearing with a corresponding pinion 0 upon the spindle I. A shifting-clutch j) allows the pinion oto be disengaged from the spindle I when desired. A sliding-door Q enables the opening from the hopper to be closed or regulated, and a movable cover R affords access when necessary to the feeding-screw M. A passage T delivers the material just inside the upper edge of the grindingring b. The pulverised material is removed from below the pan by conveyers U or other means. By the novel methods of construction described and shown, the bearing-surfaces of the driving apparatus are completely protected from dust and dirt, and are perfectly and accurately adjustable, so as to be very durable. The material to be pulverised (after having been reduced to a certain size) is supplied regularly and uniformly, and the output is very large ; and by means of the revolving fanblades i a current of air is caused, which is drawn in through the conical casing g, and prevents any escape of dust. In dry pulverising the fine material that passes through the screens falls downward through the openings d outside the ring into the receptacle c underneath, from which it is carried by a conveyer provided for that purpose. The fan attached to the shaft above the roll draws air in at the top of the cone, forcing it through the screen and out into the discharge, thus effectually keeping all dust within the mill. In wet pulverising the water is introduced with the feed, and when the mill is running the water takes the same motion as the material in the dry mill, carrying with it the ore, both coarse and fine. The fine material, with the water, composing the pulp, passes through the screens into a surrounding trough, and is discharged on one side, whence it may be passed over plates or into an amalgamator or concentrator as desired. In the reduction of mineral ores by the improved mill the percentage of slimes is less than from stamp-mills or from any other pulveriser, and for all processes of after-treatment the ore is left in the very best condition. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. In pulverising-mills in which a suspended revolving crushing-roll is pressed by centrifugal force against a fixed ring, the method of suspending the roll by means of a vertical shaft having a ball at its upper end and two transverse trunnions, in combination with a driving-pulley having an internal spherical bearing upon which the ball rests, and vertical recesses, and plates in which the trunnions work, a hollow conical bearing upon the pulley, a corresponding external cone carried by the frame of the mill, adjusting-screws and friction-plates for adjusting the pressure upon the cones, a spherical friction-plate above the ball, and a spring between the said friction-plate and the top of the pulley, all substantially as and for the purposes set forth and illustrated. 2. In combination with the parts claimed in claim 1, the feeding apparatus, consisting of a hopper, a chamber containing a feed-screw driving-gear, consisting of a vertical shaft driving the feed-screw by toothed bevelled wheels, and driven by cone-pulleys upon its upper end and upon the driving-pulley described in the first claim ; a passage delivering the material above the ring against which the crushing-roll works; and doors for regulating the supply and affording access to the parts of the feeding apparatus, substantially as set forth and illustrated. 3. In a dry-crushing mill, in combination with the parts described and claimed in claims 1 and 2, the fans upon the driving-shaft above the crushing-roll, the perforated screens surrounding the suspended shaft, the openings surrounding the pan, and communicating with a chamber below in which a conveyer works, all substantially as set forth and illustrated. . 4. In a wet-crushing mill, in combination with the parts described and claimed in claims 1 and 2, the stirrers below the crushing-roller, the perforated screens surrounding the suspended shaft, a trough surrounding the perforated screens, and a discharge-opening from the trough, all substantially as set forth. Dated this 2nd day of January, 1896. Ammi Vining Young.
Improvements in Stamping Apparatus for crushing Ores and other Analogous Stamping Purposes. I, Donald Barns Morison, of Hartlepool, in the County of Durham, England, engineer, do hereby declare the nature of my invention for " Improvements in Stamping Apparatus for crushing Ores, and other Analogous Stamping Purposes," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement: — According to this invention the downward or operative strokes of the stamps in a stamping, crushing, or hammering apparatus adapted for crushing minerals, ores such as gold-ores, and other substances, or for other purposes for which such stamping or hammering apparatus is suitable, are effected by the action of gravity and for speeds at which the number of strokes in a given time exceed what is practically obtained by gravity (less retardation due to friction). The movement due to gravity is supplemented by motion imparted by friction from positively-driven parts of the apparatus, and the return upward strokes of the stamps are effected by the rising movement of the said positively-driven parts communicated to the stamps through bodies of liquid, either alone or in combination with other elastic bodies, as will now be explained. Referring to the accompanying illustrative drawings, Figure 1 shows partly in cross-section and partly in side elevation, and Figure 2 in front elevation, a stamp-head provided with one arrangement of operating mechanism according to this invention. Figure 3is a front elevation showing a battery of ten stamps provided with such operating mechanism.

In this arrangement, to a crank 1 (or its equivalent) on a driving-shaft 2 is attached a con-necting-rod 3, jointed by a vertically-guided rod 3a to a cylinder 4, so that when the crank revolves the cylinder will be moved up and down in a straight line. Within the cylinder is a piston 5, the rod 6 of which passes through the cylinder-bottom and a stuffing-box 7, and constitutes the stem to which the stamp-head Bis attached. At a distance above the bottom of the cylinder 4 there is a port 9, which communicates with a chamber 10 that is also in communication with the cylinder above the piston through a port 11. The cylinder below the lower port 9is filled with liquid 12— for example, water —and the chamber 10 also contains liquid 12a, above which is an air-space 13. With this arrangement, when the bottom of the piston 5 closes the lower port 9, and the cylinder moves upwards, the piston 5 and stamp-head 8 will be supported by the cushion or buffer of the liquid 12, and if none of this escapes, and the strokes of the cylinder 4 per minute do not exceed the maximum number which the stamp-head 8 could make under the action of gravity minus the loss through friction, then, if the stroke of the stamp-head is equal to the stroke of the cylinder, the position of the piston 5 within the cylinder 4 will remain constant, and the liquid 12 will be practically undisturbed. If, however, the strokes of the cylinder 4 are increased in number in a given time beyond the number of possible strokes of the stamp-head 8 due to gravity alone minus friction, and if the lengths of the strokes of the stamp-head and the cylinder are equal, then, the velocity of the cylinder in the early part of its stroke being, in consequence of the cylinder being driven from a crank-pin, in excess of the velocity of the falling weight due to gravity minus friction, it follows that the friction between the piston 5 and the wall of the cylinder 4, as well as between the packing in the stuffingbox 7 and the piston-rod 6, will increase the velocity of the falling stamp-head up to the point of synchronism —that is to say, up to the point where cylinder and stamp-head move at the same velocity ; consequently, for all parts of the full stroke up to that point the velocity acquired by the stamp-head will be increased. By increasing the length of the stroke of the cylinder beyond the length of the full stroke of the stamp-head the increased velocity imparted to the stamp-head will be still further increased. In the case of an 8 in. stroke of cylinder and a 7 in. stroke of piston and stamp-head, at the end of the down-stroke of each the position of the bottom of the piston would be higher in the cylinder than the point of cut-off, thus establishing communication between the cylinder 4 and the chamber 10 through the port 9, and allowing any deficiency of liquid through leakage or otherwise to be made up, and at the same time compensating automatically for the wearing of the shoe and die. When the stamp-head is prevented from making its full stroke by the ore in the crushingbox 14, then the piston will be still higher within the cylinder at the end of the stroke of the latter by a proportionate distance, and the volume of liquid below the piston in the cylinder will be increased. On the upstroke of the cylinder the surplus liquid will flow back into the chamber until the cut-off position is reached—that is to say, until the lower edge of the port passes the lower edge of the piston, and so closes the port, thereby reducing the shock at the point from which the piston and stamp-head are raised. To further aid in reducing the shock, the port 9 may advantageously be made of V-shape, the smallest end of the port being at the bottom. It will be seen, therefore, that the differential motions of the cylinder and of the piston, particularly when the stroke of the cylinder is greater than the stroke of the piston, is such that a considerable increase in the number of strokes per minute can be obtained beyond those which are obtainable with the ordinary cam construction, by reason not only of the reduced friction of mechanism, but also by the assisting effect of the friction between the wall of the cylinder 4 and the piston 5, and between the packing in the stuffing-box 7 and the rod 6. It will be obvious that to obtain the greatest number of blows in a given time with this arrangement the rate of rotation of the driving-shaft 2 must be such that the velocity of the cylinder 4 in the downstroke shall not be less than the possible velocity of the piston due to gravity minus friction. The retarding effect of friction to the downward movement of the stamp-head may be eliminated altogether by surrounding the piston-rod 6 with a sleeve 15 connected to the cylinder, and arranged to work in the fixed transverse guide 16, through which the said rod ordinarily works. By this means the friction of the guide will be transferred from the falling rod to the positivelydriven sleeve. The cylinder 4 may be guided vertically in its movements by providing it with extensions 17 arranged to work on a guide-rod 18 fixed to the upper and lower tranverse guides 16a, 16 that form part of the framing of the apparatus. In order to minimise the leakage of liquid from the cylinder 4 through the stuffing-box 7, the latter may be fitted with a gland 19, formed with an annular recess 20 into which any liquid passing down the rod will flow, and whence it can pass back into the chamber 10 by a passage 21 and pipe 22. The tightness of the gland 19 may in this case be insured by a supplementary gland 23, which may conveniently be formed in one with the sleeve 15. The chamber 10 may be arranged behind the cylinder 4, and, as will be seen from the drawings, can be made of a capacity which will admit of the apparatus being applied in connection with the stamp-heads of existing stamp-batteries, and which are usually pitched at a distance apart of about 10 in. from centre to centre. Figure 3 shows the apparatus applied in connection with a stamp-battery containing ten stamp-heads. The applicability of the apparatus to existing stamp-batteries is a feature of considerable practical importance. Any suitable means may be employed for imparting an intermittent rotary movement to the stamp-head when desired. Figure 4 is an elevation, and Figure 5 a plan in section, showing an arrangement for this purpose, in which there is provided in connection with a toothed wheel 24 fixed on the rod 6 a pawl 25, carried by a bracket 26, the arrangement being such that the wheel 24 will engage the pawl 25 on the upstroke, and the pawl, turning upon the centre 25*, will revolve the piston-rod by means of the attached wheel 24 through a small portion of a revolution. 27—C. 3.

The chamber 10 is or may be fitted with a valve 26 (Figure 10) or a perforated cap, to allow for any variation of pressure in the chamber either above or below the pressure of the atmosphere. Suitable means are provided when it is desired to be able to vary the stroke of the stamp-head. Figure 6 is a vertical section showing one arrangement for this purpose, in which additional ports 9a are made m the side of the cylinder 4 at levels corresponding to the length of the stroke required. The ports 9, 9a in such a case are each provided with a valve 27, capable of being readily controlled by a handle 28, so that ports not required for the time being can be readily closed, and that which it is desired to use can be readily opened. Figure 7 is a vertical section showing another arrangement for this purpose, in which the cylinder 4 has formed in its inner surface a longitudinal groove 4 a , in which is an adjustable slidebar 29, formed with a rack in gear with a pinion 30, by suitably moving which from the exterior of the cylinder the closing of the communication between the two ends of the cylinder by way of the said groove 4 a can be caused to take place at any desired part of the stroke of the piston 5 relatively to the cylinder 4. It will be evident that (if so desired) the piston may be connected to the crank so as to be actuated thereby, in which case the stamp-stem will be attached to the cylinder, or (as represented in Figure 8) the cylinder, actuated by the crank, instead of having a hole through the bottom, may have the stuffing-box at its top, a cross-head 6 a being attached to the upper end of the piston-rod, and connected to an upwardly-extending bifurcated portion 6 3 of the stamp-stem 6. The cylinder may be prolonged below the cut-off port to such an extent that in the event of escape through leakage of the whole of the liquid from below the port the piston will not strike against the cylinderbottom, or below the port there may be a spring adapted to act when necessary in lieu of liquid during the return or upward stroke of the positively-driven parts and stamp. In Figure 9 there is shown a spiral spring with an annular plate above it; but there might obviously be substituted some other form of spring, such as an indiarubber buffer-spring. If it is desired that the revolutions of the driving-shaft 2 shall be less in number than heretofore mentioned, and that the apparatus shall still embody the requirements of a gravity stamp, then, at the lower end of the cylinder 4 (Figures 10 and 11) there is placed a valve that is capable of being actuated by any suitable means (it may be an eccentric, tappets, cams, or other equivalent devices), in such a manner that communication between the interior of the cylinder and the reservoir is opened and closed as required. Figure 10 is a vertical section, and Figure 11 a side elevation, showing an arrangement of this kind, wherein 31 is a valve controlling a port 9 ;: arranged at the bottom of the cylinder 4 for placing the same in communication with the chamber 10. In this case the arrangement, as will be seen, is such that the piston 5 and stamp-head will be lifted through the medium of liquid 12 imprisoned below the piston, as in the arrangement shown in Figures 1 to 8, and they are allowed to fall under the action of gravity, and independent of the movement of the cylinder 4, by opening the valve 31 so as to establish free communication between the cylinder 4 and the reservoir 10. The cylinder is prolonged upwards so as to prevent its upper end coming in contact, on the down-stroke, with the piston in the event of the stamp-head being prevented from making its full down-stroke ; and at that point of the upper portion of the cylinder at which the piston will be located when a full stroke of the cylinder has been made there is an opening IP between the cylinder and reservoir through which liquid can pass in order that the stamp-head will not be raised until the relative normal position of piston and cylinder is reached, so that the stamp-head will never be raised beyond a predetermined height, no matter what proportion of the full stroke it may have dropped. Or, in lieu of the port 11°, there may be a port 5° in the piston 5 wmich is opened and closed by a rod (see Figure 12), thus dispensing with the independent chamber. The controlling-valve 31 may be of any suitable type, such as a rotary valve having a slotted periphery as shown, and be operated at the required times through an arm 31 a on its stem by moving tappets 32, 32" on a rod 33 worked from an eccentric on the drivingshaft or by fixed tappets. In each arrangement any one of the rods 6 with stamp-head 8 can, when desired, be held up or out of action without interfering with the working of the remainder of the series. Obviously this invention will enable stamps to be operated more rapidly than has been found practicable where gravity alone has been relied upon for effecting the downward strokes, because, as is well known, in stamp-batteries of the kind in which the stamp-heads are allowed to fall through a distance of about 7 in. by gravity, and are raised by cams or wipers, it has hitherto been impracticable to obtain more than from 100 to 105 blows per minute, and of the power expended a large proportion has been wasted in friction; whereas my invention renders it practicable to neutralise the retarding effect due to friction, and, when necessary, to supplement the force due to gravity, thereby rendering it possible to obtain a greater number of blows per minute and a greater crushing-capacity per stamp-head, whilst, by obviating to a large extent sudden shocks, the apparatus is also rendered less liable to break down than apparatus of the ordinary construction, and of the power expended a larger proportion may be usefully employed than heretofore has been usual. As will be obvious, the essential feature of this apparatus renders it suitable not only for the purposes indicated, but also for operating dies, for sharpening rock-drills and the like, and for various other hammering purposes. I reserve the right to modify details of construction to suit different requirements. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. A stamping apparatus (for crushing minerals, gold-ores, and other crushing, stamping, or hammering purposes) characterized by the peculiarity that the downward or operative strokes of the stamps are effected by the combined action of gravity and motion imparted by friction from
205
C.—3
positively-driven parts of the apparatus, and the return or upward strokes of the stamps are effected by a rising movement of the said positively-driven parts, communicated to the stamps through bodies of liquid. 2. A stamping apparatus of the kind referred to in claim 1, in which there are combined with the stamps and their attachments and the positively-driven parts springs adapted to act when necessary in lieu of liquid during the return or upward strokes of the positively-driven parts and stamps of the apparatus. 3. In stamping apparatus of the kind referred to in claim 1, a stamp connected by a rod to a piston which is located within a cylinder that is arranged to have a vertical reciprocating motion imparted to it, and between the bottom of which cylinder and the bottom of the piston there is a body of liquid, the arrangement being such that the rod and attached stamp-head will be lifted by the cylinder through the medium of the liquid, and during descent of the stamp-head its velocity will, when the cylinder is driven with sufficient rapidity, be increased beyond that ordinarily due to gravity (after allowing for retardation due to friction) by reason of the frictional driving-connec-tion which will then obtain between the positively-driven parts and the parts in mechanical connection with the stamp. 4. Stamping apparatus according to claims 1 and 2, in which the stroke, of the drivingcylinder 4 is made greater than that of the stamp-head 8 and connected piston 5, and there is a communication between the lower end of the cylinder and a chamber or reservoir containing liquid, so that the downward velocity of the stamp-head can be further increased beyond the ordinary velocity, and a communication will be opened between the cylinder and chamber to allow of liquid passing from the latter to the former to insure that the space between the piston and cylinderbottom shall at all times be full of liquid, and in this way prevent undue shock when the cylinder again moves upward, besides automatically compensating in whole or in part for the wearing of the shoe and die. 5. Stamping apparatus of the kind specified in the preceding claims, in which provision is made for opening communication between the cylinder 4 and the liquid-chamber 10 at different positions of the piston 5 in the cylinder, so as to enable the stroke of the stamp-head to be varied to suit requirement. 6. An arrangement of the kind referred to in claim 4, wherein the wall between the cylinder and liquid-chamber is formed with two or more holes 9°, arranged at different heights, and each controlled by a valve. 7. Stamping apparatus of the kind referred to in claim 2, in which the cylinder 4 has a vertical groove in its inner surface controlled by an adjustable rod capable of being operated from the exterior of the cylinder. 8. The modified construction of the stamping apparatus referred to in the preceding claims, in which the stamp-head is lifted through the medium of the liquid between the bottom of the cylinder 4 and the piston 5 connected to the stamp-head, but is allowed to descend in relation to the said cylinder by permitting the liquid to escape from the cylinder into the chamber 10, through an opening 9*, controlled by a suitably-operated valve 31. 9. Stamping apparatus constructed, arranged, and operating substantially as hereinbefore described with reference to and shown in Figures 1 and 2, or modified according to Figures 4 and 5 or according to Figure Dated this 4th day of September, 1896.

SUMMARY OF WORKS CONSTRUCTED— continued.
It will be seen from the foregoing statement that works to the value of £102,915 were authorised during the past year, as against £35,782 for the previous year, whilst the expenditure during the period referred to was £44,771, as against £31,922 for the year previous, leaving the liabilities on works authorised and in progress on the 31st March last to be £69,616. The actual cost of works undertaken, completed, and in progress during the last fourteen years that votes for this purpose have been under the direct control of the Mines Department for the development of the goldfields has been £616,351, out of which the Government has expended £424,813 in subsidies to local bodies and direct grants for the construction of the different works, whilst £191,538 has been contributed by local bodies and prospecting associations. In furnishing the foregoing report it has been my endeavour to follow the lines adopted in preceding reports. In consequence of my appointment being made in the middle of the year it was beyond my power to make a personal inspection of all the mines and note the special requirements in the different districts throughout the colony. Quartz-mining having attracted the chief attention of the investing public, reports on that branch of the industry have been prominently dealt with, and I have advanced opinions based on past experience respecting the success, probable advancement, and permanency of the profitable mining and treatment of ores. The introduction of capital, which is being devoted to further develop the mines in the more important mining districts, and to carry on explorations in the lately-discovered quartz reefs, will further extend the area of production, and the effective nature of the machinery which is being introduced, by lessening the cost of production and extraction, should increase the returns of gold. The alluvial deposits, the river-beds, and the accumulations of auriferous drift which occupy such extensive areas throughout the west coast and the southern portions of the Middle Island will in future receive that notice their importance warrants, but to which, through force of circumstances, I have been unable to direct as much attention in the present report as I should wish. Dredging operations are being conducted with profit in Otago and Southland, and there are numerous places where the gravels on the higher lands contain sufficient gold to pay if water were available for sluicing operations to be carried on. In order to render alluvial workings, hydraulic sluicing, and dredging more profitable an increased water-supply is necessary, and without doubt there is room for the investment of capital in the construction of water-races and dredges. The mining industry generally would at present appear to be in a more satisfactory condition than it has been for many years past, and I fully expect that by the judicious expenditure of the capital which has been directed to this colony towards the expansion of mining it will be my pleasing duty next year to report a continued advancement in all branches of the industry in New Zealand. I have, &c, Geo. Wilson, Inspecting Engineer.
