PUBLIC WORKS STATEMENT (BY THE HON. E. A. RANSOM, MINISTER OF PUBLIC WORKS).

Mr. Speaker,— On assuming the portfolio of Public Works I realized from tlie outset that it was necessary for me to become fully and personally acquainted with the special conditions concerning the various works already in hand, and to become familiar with the officers of the Department, in order that I could more readily grasp the multifarious operations in which they were involved. I therefore devoted practically all the period of the recess to travelling and to visits of inspection to the larger works which the Department had in hand. I feel that the personal touch which I have been able to establish with both the officers and the men has been for the good of all parties and for the increasing of that harmony which is so essential if the best progress is to be made. The personal knowledge gained has been of benefit to myself, and I trust will be of benefit to the country as a whole, for I have not confined my inspections to the Department's operations only, but I have endeavoured to ascertain through my own observations and through conferences with those most directly concerned just what were the most pressing requirements of the different districts. The backblock districts in particular received my earnest attention, and it is my confirmed opinion that considerably more must be done than has been done in the past in regard to the provision of improved access to those areas. I have accordingly arranged that the vote on the public-works estimates for this year for access to outlying districts is to be materially increased, in order that not only access to those districts already settled may be improved and extended, but that those areas suitable for settlement may be roaded as an inducement to further settlement. In this direction I may say the Public Works Department and the Lands Department will operate conjointly, and increased settlement of many of those areas of land at present unoccupied and reverting to second growth may confidently be expected.

Honourable members have already received the Government's proposals regarding land-settlement, and it is the Government's desire to, as far as possible, employ on the development of unsettled and unproductive lands under the provisions of the Land Laws Amendment Bill of this session many of the more experienced Public Works employees who by their long and faithful service have shown that they possess many of the necessary qualities that go to make successful settlers, and it is hoped that they will avail themselves of the opportunities of obtaining farms that are being offered under that legislation. By this means the way will be opened for employment on standard works of my Department of more of the ordinary unemployed. Unfortunately, during last recess available time would not permit of my visiting some of the more northern parts of the country, but it is my intention and desire to devote as much time as possible to travelling in those localities as soon as can conveniently be arranged after the session. In connection with railway-construction, during the year 106 miles 30 chains of lines have been completed and handed over to the Working Railways Department for ordinary operations. Tn addition to the lines handed over for incorporation in the railway system, traffic has been carried on by my Department on sixty-nine miles of railway which are either not absolutely complete or the control of which by my Department is essential in the interests of economy of construction of other portions not yet completed, but which are so interconnected with the completed portions as to indicate that the control should still be retained in the hands of the Public Works Department. The Government, after full consideration, decided that the railway which was being built from Rotorua to Reporoa—a distance of about twenty-eight miles — should be discontinued, and also that the deviation of the Main Trunk line at Palmerston North which had been put in hand by the previous Government was not justified at present. Accordingly these works were stopped, and the men, plant, and material which had been employed on these works were transferred to the Gisborne-Napier Railway, on which it was decided to accelerate progress. The extension of the North Auckland Main Trunk Railway is not proposed beyond Rangiahua, where the railway will make contact with the Hokianga waters. The difficulties of railway-construction in the North Auckland district are phenomenal, the instability of the ground rendering either road or railway construction particularly expensive. However, it is considered that so much money has already been, spent on the final section, and also on the link which will bring the DargavilleKaibu Valley Railway in connection with the Northern Main Trunk line, that it is advisable bo complete these portions in order that the districts to be served may have the advantage of railway convenience. The results obtained from the working of the East Coast Main Trunk Railway, and the benefit which it is conferring upon the population up to and even beyond its present terminus at Taneatua, are such that I hope it will be found justifiable to proceed with the extension of this railway towards Opotiki when some of the other works now nearing completion are out of hand. Prior to my assuming office the question of the route of the Napier-Gisborne Railway between Wairoa and Gisborne had been the subject of a great deal of controversy, and many reports had been made on the subject. I reviewed the whole position and with my colleagues gave the matter close attention, with the result that it was decided that what has come to be known as the coastal route should be adopted. This route, in addition to saving about eight miles in actual distance, reduces the amount of new line to be constructed by twenty-six miles, and therefore very greatly reduces the time which must be spent in construction before a through connection can be made. Work on this line is now being prosecuted vigorously, there being approximately 1,200 men engaged, as well as numerous steam - shovels, locomotives, and other mechanical plant. The construction is being attacked in three main directions —northwards from the

D.—l

present, railhead near Waikare, northwards from Waikokopu, and southwards from Gisborne. In view of the use which the Department is making of the Port of Waikokopu, both in connection with the railway - construction and the Waikaremoana hydro-electric development, a considerable amount of money has been spent on facilities there, and a small breakwater is under construction, the whole being in accordance with an arrangement made with the Wairoa Harbour Board under which they will later on repay to the Government a great proportion of the cost of the works. At the Gisborne end a further survey is being made to ascertain whether the distance cannot be materially shortened, it being realized that, in order that the railways may effectively compete with road transport, directness between large centres of population is essential, even though this may involve some extra expense. A considerable portion of the line between Waikokopu and Muriwai will be remote from the main road, and it has been found necessary to do a great deal of development work in the nature of access roads, trams, and jig-lines before the railway proper can be commenced. These access facilities, which are directed to the early commencement of the crucial points on the line, are now well advanced. The Stratford Main Trunk Railway is also being vigorously prosecuted, and is manned 011 a maximum scale, three shifts and all available plant being worked on the governing points, which are mainly the tunnels, there being no less than four miles of tunnel between the present railheads. A coal-mine has been opened in the Tangarakau Gorge, and others are in contemplation in the same formation. Special coal-loading sidings are under consideration at Raekohua Station, so that heavy traffic on this line will soon materialize. It has also been decided that the construction of the last link in the PictonBluff Railway—namely, the part between Parnassus and Wharanui— should be resumed as soon as the route had been decided upon and the necessary surveys completed. At the northern end there is a considerable distance on which only one route is available ; sufficient of this has been pegged out, and a commencement with construction has been made. On the remaining length surveys are in hand and the route is being pegged. Work on the railway designed to connect Westport and Nelson with the rest of the railways of the South Island by a junction with the present West Coast lines at Inangahua Junction is being vigorously pushed forward. Unfortunately, the disastrous earthquake which so badly damaged the northern end of the South Island on the 17th June, 1929, interrupted this work, it being necessary to transfer almost the whole of the men from the railway-works to open up road communications in the adjoining districts. The dislocation of the ground throughout the whole length to be followed by this railway has resulted in a great number of enormous slips, in addition to rendering unstable the ground which has not yet slipped. The result of this will be a great increase in the cost of this railway over and above what it would have been estimated at prior to the earthquake. The line has not yet been surveyed in detail throughout, but as soon as it is possible to open up a packtrack to allow engineering surveyors to penetrate the country the survey will be resumed. The total vote proposed for railway-construction this year is £1,655,000, this being a very considerable increase 011 the £1,002,872 spent last year. The rate of progress 011 railway-construction has been generally expedited in accordance with the Prime Minister's policy of bringing the railways under construction to a paying-point as early as possible. The reason for this is obvious, particularly as this policy also enabled the employment of additional men 011 reproductive work rather than 011 relief works, which, although useful works and eventually necessary, were not so urgently required by the country. In addition to the railways being constructed from the ordinary Public Works Fund, my Department has been carrying out two very large works with funds derived from what is known as the Railways Improvement Account. These deviations are in the vicinity of Auckland and Wellington. What is known as the

D.—l

IV

Westfield Deviation, which is being constructed in order to obviate the steep grades which, combined with heavy suburban traffic, cause congestion between Auckland and Penrose, is now nearing completion. Goods traffic to a limited extent is now in operation over one of the tracks (this being a double-track deviation). It will not be possible to open the deviation to traffic of all classes until the new Auckland Railway-station and the yards which form part of it are ready for use. This latter work is being carried out under a contract let by the Minister of Railways. The Tawa Flat Deviation, which will cut out the heavy grades and circuitous lines between Wellington and Tawa Flat, is now being energetically pushed. Every available face in the tunnels is manned. The very latest tunnelling machinery has been installed, with the aid of which it is hoped to considerably further increase the number of men engaged. During my term of office two notable forward movements have been made in connection with hydro-electric-power development in that the first unit from Waikaremoana, nl 20,000 kilowatts capacity, was put on load at the end of January, 1929, thereby relieving the severe stress which for some time had been thrown on the Mangahao Station, and at the beginning of June, 1929, the first unit at Arapuni, of 15,000 kilowatts, commenced to deliver power on a commercial scale, and has since then been running practically fully loaded. The second unit is now ready, and commenced carrying load at the end of September. It is anticipated that the third unit will be operating before the end of the year. It is a source of satisfaction to the Government that its officers have been able to demonstrate that the claim made by the contractors that it was impossible to erect a power-house on its present site had no foundation in fact. In connection with this development, however, I regret to say a very extensive erosion—much more rapid than was anticipated — has manifested itself in the old bed of the Waikato River below the spillway over which the surplus water escapes. The position has been aggravated by the fact that, owing to the contractors abandoning the contract, the channel has been subjected since the end of 1927 to flows of water which were not anticipated, and which would have been considerably mitigated had the power-house been in full operation taking a large amount of water which otherwise has had to go over the spillway. As a consequence protective measures must be taken, and this work is being energetically handled. The driving is proceeding of two additional penstock tunnels, which are part of the subsequent development of the scheme, and which will be available when, through growth of load, the time arrives for the installation of additional generating machinery. It is estimated that these two tunnels, together with the other four of the present development, will be capable of taking the normal flow of the river, and any additional flow, in all but extreme floods, can be diverted through the existing bypass tunnel round the dam. Work on the Waitaki River, where a large development is being made about four miles above Kurow, is proceeding satisfactorily. A coffer-dam of interlocked steel-sheet piling has been completed, enclosing a section in the centre of the river, and the rock has been laid bare in the bottom. When this section is concreted the dewatering and concreting of the remaining sections in the main stream will be greatly facilitated. So far the work has been quite successful, although, in common with all work carried out in rivers subject to flood, there must be considerable anxiety so long as the works are in a condition which renders them vulnerable to the attacks of a large flood. However, every precaution which can economically be taken is being taken. For some time it has been suggested that it will be to the advantage of both parties if an agreement can be arrived at whereby the Government purchases the City of Dunedin's Waipori development, at least so far as the main generation and transformation is concerned, and negotiations have been in progress. Whether these will be finalized or not has not yet been decided, as quite a number of considerations other than strictly commercial factors surrounding this transaction must be considered. Detailed investigations have been in hand in regard to what is known as the Gowan hydro-electric scheme in the Nelson District. The damage resulting from

D.—l

V

the recent earthquake has affected the position, and it is not possible to give any definite indication in regard to this scheme pending further investigations, which are now in hand. The roading operations of the Department, particularly the provision of communication facilities for the people in the backblocks, as previously stated, has been one of my closest studies. The ultimate goal to which I aspire is that of providing every landowner with such access as will enable him to transport his produce from the farm to the seaboard with celerity and economy at all times in the year, and which will furnish to him and his household the convenience of easy access to their ordinary markets and to their fellow-citizens of the Dominion. The graph contained in this Statement shows that the steady increase in the cost of roading which has been manifest in the ten years prior to my taking office is still maintained. The ever-increasing number of motor-vehicles using the roads precludes the possibility of any decrease in roading expenditure if the present high standard is to be maintained. Honourable members are perhaps aware, but there will be 110 harm in repeating the fact, that, when considered in proportion to the population and the number of motor-vehicles, New Zealand is in the forefront amongst the nations in its mileage of roads available for traffic in all states of the weather—in other words, hard-surfaced roads. In preparing the public-works roads estimates for this financial year I have amended to some extent the system of allocation of the roads vote to the different districts which has been in use for some years past. A careful review of the operation of this system indicated quite conclusively that it was not applying as equitably as could be wished, and it was quite apparent that while some districts were receiving unduly liberal treatment others were being penalized. The governing factor responsible for this position appeared to be that known as " paper roads." A perusal of any standard county lithograph will show the great number of legalized but unformed roads, a great many of which there will be no necessity to construct for very many years. Under the old system of allocation of funds these were all taken into consideration in allotting the roads vote, and the greater the mileage of unformed roads the greater the amount of money the district would receive, even though perhaps many of the roads would never be formed. This appeared to be hardly reasonable or fair, and the incidence of this factor to a great extent appeared to upset the balance of the other factors. I therefore amended the system in this respect and took into consideration only those legal unformed roads which a careful review indicated might be expected in the course of development to receive attention in the next few years. Other amendments to the automatic system of a more or less minor nature have also been made, and, although a certain amount of criticism has been received as a result of the alterations from those districts whose allocations have been reduced, it is felt that so far as the whole Dominion is concerned the system will now operate in a much more equitable manner than formerly, and those districts most in need of development will get the assistance from the roads vote to which, when all factors are considered, they are justly entitled. Further details regarding this automatic allocation scheme appear further on in this Statement. The Main Highways Board has continued the excellent work which it has done in the past, and I found that it enjoys the confidence of the local bodies with whom it is in such close touch, and that the local authorities and motorists generally are not stinting in their appreciation of the great improvement that has taken place in the roading of New Zealand since the Highways Board was constituted. During the year the main-highway system was extended to include 3,753 miles of secondary highway, while the general maintenance subsidy for the whole system, which now comprises 10,403 miles of main highway, was increased from £l 10s. for £l to £2 for £l. The Board in its report (which is attached) shows that, mainly in consequence of the increase in the rate of maintenance subsidy, local authorities were able to considerably reduce the amount which they paid towards the cost of maintenance of the primary highways system. The amount of this reduction, however, does not approach the amount of the increase in local-authority rates which

D.~i

VI

has taken place during the last few years. Between 1924-25 and 1927-28 the rural rates increased by £178,000 per annum, and a large percentage of this increase was accounted for by the additional expenditure which local authorities had to face in the maintenance of primary highways. 1928-29 rural rating figures are not yet available, but in view of the increased operations of the Board it is reasonable to expect that the rise of rural rating has been arrested. Since I assumed office numerous local authorities have made representations to me for payment towards the cost of construction of roads put down in what are generally referred to as " permanent materials," and towards the cost of which the local authorities concerned did not receive a subsidy, or received a subsidy which in their opinion was insufficient in comparison with the subsidies which are now being paid. The matter is one to which I have given a good deal of consideration, as 1 fully appreciate the local authority point of view. I have, however, been forced to the conclusion that the finances which are available for road construction and maintenance purposes will not permit of such payments being made. The finances which are at present available are such as will meet present and future requirements only, and if retrospective subsidies in any form were to be paid, either as a direct payment to local authorities or as an annual grant towards the payment of interest and sinking-fund charges, it would be necessary to either increase taxation or reduce the present rate of subsidies, and J cannot recommend the adoption of either of such courses. In regard to irrigation in Central Otago, the late Government set up a committee, consisting partly of Government officers and partly of settlers in Central Otago, to investigate matters relating to the irrigation schemes in operation in that locality. The settlers had contended for some time that the rates they had agreed to pay for water were too high, and that the amount of water which the Government had contracted to supply to them was insufficient. As the quantity of water and the price to be paid for it was the fundamental basis on which the schemes had been established, it became a matter of very serious consideration. When f took office i found a report already brought down. The investigating committee found in a number of cases the settlers had been too optimistic and had contracted to carry out more than their land could support, at any rate until the same was fully developed, and its full development could not be brought about for a period of years. The committee recommended certain modifications to the agreements made with the settlers ; and after visiting the districts and interviewing a great many interested persons I found that the whole subject bristled with difficulties, but that nevertheless the practical result to New Zealand in the way of increased produce, thereby inducing increased traffic on the railways and increased revenue of public utilities, was so great that considerable sacrifice by the Government in the early stages would undoubtedly be offset by the benefit to the Dominion as a whole. I therefore agreed to grant for a period of five years the Concessions recommended by the investigating committee, being confidently of the opinion that by that time the settlers would all be firmly established on their holdings and would be well able to pay the charges which they originally contracted to do. The position regarding unemployment has, since my assumption of office, given me cause for grave concern, and much thought has been devoted to how the problem could best be handled. On assuming office I found that 2,935 men were engaged on relief works by my Department, at a wage of 9s. per day for single men and 12s. per day for married men, the standard rate of wages being 14s. per day. The Government considered the matter and decided that the wages of relief workers were to be raised to the standard rate of 145., and this was immediately done. While endeavouring to arrive at a permanent solution of the unemployment problem I have not lost sight of the fact that immediate relief was urgently necessary, and my Department has used every effort to absorb the maximum number of men possible on its various works. The placing of large numbers of men on public works is, however, not a permanent means of overcoming the difficulty. The Government, realizing this fact, has given very full consideration

VII

D.—l

to various schemes which would mean the permanent removal of considerable numbers from the ranks of the unemployed, and it is anticipated that (hiring the present summer several of these schemes will be finalized and put into operation, thus materially relieving the position so far as next winter is concerned. As honourable members are aware, the Government has given an undertaking that all unemployed capable of employment will be placed in work at a certain date. A sub-committee of Cabinet has the matter in hand, and proposals in this direction are at the present time receiving that committee's attention. EXPENDITURE. The total net expenditure under all votes and accounts appearing on the public-works estimates for the financial year ended 31st March, 1929, was £8,331,884. Of this sum £3,777,006 was expended out of General Purposes Account, and the balance, £4,554,878, out of special accounts. A brief summary of this expenditure, as well as the total expenditure since the inception of the public-works policy to the 31st March la,st, follows in tabular form : —

The ratios which the various classes of expenditure on works bear to the whole are indicated graphically in the diagram below.

RAILWAY-CONSTRUCTION. The expenditure as shown on graph has been much, heavier than that of the previous year, and constitutes a record. The total length of all lines under construction over which goods and passenger traffic has been run during the year is 69 miles, and these services have been of great service and benefit to the settlers who could take advantage of the railway. This is in accordance with the Department's policy of making works earn revenue at the earliest possible moment, and giving the public the advantage of the facilities as soon as can safely be done. The schedule attached is a complete statement of the work on railways now in progress and the extent to which it is anticipated the railways can be completed during the next two years. The work for the year on the several lines in course of construction is fully set out in the Engineer-in-Chief's report, and may be summarized as follows : — North Auckland Main Trunk Railway. —The construction of this line was confined to the Rangiahua Section, and the work is being pushed ahead as much as possible between Okailiau and the upper waters of the Hokianga Harbour. The country is most unstable, and has given considerable trouble with slips over the whole 14 miles. So treacherous is the country that the railway has had to be deviated in many places for an aggregate distance of 2| miles to avoid slips which developed after the ground was opened up. A quarry has been, opened up near Okaihau, bins have been erected, and crushers installed to obtain ballast for the line.

Dargaville Branch Railway.—The construction of this line has made rapid progress. The formation is completed for 7 miles, with the exception of three bridge approaches along the route. Ballasting has been completed for 4 miles, the stone being obtained from the Department's quarry at Tauraroa. The country has been difficult to work, as the river-flats are not sufficiently strong to carry embankments. Station-yards are being constructed at Tangowahine and Wharau. Four steam-shovels are at work. Telephone-line has been erected for a distance of 10 miles. Auclcland-Westfield Deviation. — This double - track deviation, which will connect the new Auckland Railway-station with the existing line at Westfield, a distance of 8 miles 70 chains, is nearing completion. The formation, culverting, and heavy bridge work are completed. The portals of the Purewa Tunnel have been built, thus completing the work. A crushing plant has been in operation to supply metal and chips for concrete-work, ballasting the tunnel, and metalling approach roads. Platelaying and ballasting is being carried out by the Railway Department. One track has been laid and ballasted throughout, and the rails have been laid on 2 miles of the other track. Six station buildings have been erected. East Coast Main Trunk Railway: Waihi Eastwards. —The Tauranga to Taneatua section, of the railway, 59 miles in length, was handed over to the Railway Department on the 2nd September, 1928. The centre span of the Whakatane Bridge was widened to make a passingplace for motor traffic. The cattle-yards at Awakeri were extended for stock. Rotorua-Taupo Railway. —On the completion of the East Coast Main Trunk Railway to Taneatua men and materials were transferred to Rotorua and a start made on the construction of the railway. Two miles of formation was completed, hutments and stores erected. On the 18th March last it was decided to discontinue the work and transfer the men and plant to the Gisborne-Wairoa Railway works. Gisborne-Nafier Railway.— -The work on this railway was' vigorously pushed ahead, and the rails were laid to Matahoura Station. Goods and passenger services were run from Eskdale to Matahoura. The formation of the Putorino Section is practically complete, and will be handed over to the Railway Department in a few months. The distance from Eskdale to Putorino is 26 miles 50 chains. The principal works completed during the year were as follows : Sandy Creek Bridge, consisting of three 60 ft. spans on steel trestles and concrete foundations ; and Matahoura Viaduct, of two 60 ft., two 40 ft., and one 250 ft. span on steel trestles with concrete foundations and abutments. The latter structure is 213 ft. above the gorge. On the Wairoa Section formation has proceeded satisfactorily. Tunnelconstruction and bridge-erection are in hand. The formation is heavy, and ten steam-shovels have been employed during the year. Six and three - quarter chains of the bottom heading of the Kotemaori Tunnel have been driven, and the north portal completed. Chimney Creek Tunnels, Nos. 1 and 2, and Waihua Tunnel, were completed. Bad conditions have beenfmet with in! the Mohaka Tunnel, in which 16|- chains have been completed. The Waikare Viaduct has progressed rapidly, and should be carrying the train by March next. Extensive investigations have been made and bores put down to determine the best type of foundation for the Mohaka|Viaduct, which will be the largest one on the railway. The Wairoa River Bridge is nearing completion. Stratford Main Trunk Railway. —On the eastern end the daily goods and passenger service between Okahukura and Ohura (a distance of 19 miles) has been maintained throughout the year, and has been a great benefit to the district.

The construction work on the whole length of the Tokirima Section is now fairly well advanced. The work is heavy, and includes six tunnels aggregating just over l\ miles. Two tunnels have been completed ; the third is being lined ; in the fourth the bottom heading has been driven ; and in the fifth (732 yards long) the bottom heading has been driven 149 yards ; the sixth is now being manned. On the Heao Section all work is being rapidly opened up. On the western end the work was mainly devoted to the tunnels, these being the factors governing the completion of the line and the early establishment of through traffic. No. 2 Tunnel (55 chains long) is nearing completion, No. 3 Tunnel (64 chains long) is well in|hand,|and the approaches to No. 4 Tunnel are being formed. A tri-weekly passenger and maintained between Tangarakau and Tahora, which connected with the New Zealand railway service. Large quantities of coal have been carried. The workmen's accommodation has been well maintained. Paimerston North Railway Deviation. —Four steam-shovels, seven construction locomotives, and two caterpillar tractors were employed on formation. The main-line formation was completed to within 42 chains of the northern junction with the Main Trunk Railway. On the 18th April last the work was closed down, and most of the men and plant were transferred to other works. Wellington - Tawa Flat Deviation. —The railway-bridge across the Hutt Road and the bridge over Ngahauranga Gorge are complete. No. 1 Tunnel has been pierced ; 40 chains of heading have been done during the year. This tunnel was exceptionally wet, and four shifts of six hours each per day have been necessary throughout the work. Plant necessary for the most rapid progress practicable in this tunnel has now been installed. At No. 2 Tunnel the approach cutting was completed. The heading has been driven for 19 chains at south end and 18 chains at the north end. This tunnel is also being worked from a shaft 53 chains from the north end, the heading being driven 17 chains northward and 15 chains southward. The necessary plant is now ready for enlarging and lining, and much greater speed should be made with these sections of the work. Midland Railway.—The formation of this railway has now been completed to Gowan station-yard, a distance of approximately 4 miles, and line has been laid and ballasted. All the station buildings at Gowan have been erected. Settlements and movements due to the earthquake of the 17th June will necessitate further ballasting-work. Formation is now in hand for 5 miles beyond Gowan. An additional 250 men were engaged on this railway during the last six months. Westport to Inangahua Railway. —On the Cascade and Hawk's Crag section of this railway the formation is complete for a distance of 5 miles, and is in hand over further 3 miles. Two large fillings and two tunnels on this portion are in hand. South Island Main Trunk Railway. —A start has been made with the formation at Wharanui, on the north end, cleaning up the portion that was formed thirteen years ago. The erection of workers' accommodation is in hand. RAILWAYS. Additions to Open Lines. The net expenditure out of the Public Works Fund for the year ended 31st March, 1929, amounted to £213,405 2s. 3d. This sum covered the provision of new rolling-stock, motor-vehicles for road service, improvements and additions to station buildings, water-services, cranes, weighbridges, and other operating plant, traincontrol lines and instruments, additional dwellings, and purchase of land.

Railways Improvement Authorization Act, 1914. The expenditure under the Railways Improvement Authorization Act, 1914, amounted to £2,007,617, including the sum of £97,791, proportion of the cost of raising the loan. The works included in this expenditure were new stations and yards, goods-sheds, and terminal facilities at Auckland and Wellington ; duplication, Horotiu-Frankton; new lines, Hutt Valley and AucklandWestfield ; new locomotive-depots at Auckland and Greymouth ; deviations between Ravensbourne and Burke's, at Palmerston North, and Tawa Flat; locomotive workshops and equipment; bridge-strengthening ; electrification of railway between Lyttelton and Christchurch, including electric locomotives ; interlocking, automatic and power signalling, telegraph and telephones, safety appliances, and electric lighting. HYDRO-ELECTRIC DEVELOPMENT. The present policy of electric-supply development may be considered as having been actively commenced when work was first started at Lake Coleridge in 1910 on the first of the main Government generating-stations. That station came into operation about the end of 1914, so that the year just completed is the fourteenth year during which Government supply has been in operation. During the past year progress has been well maintained. The annual expenditure was £943,807, increasing the total capital spent on hydro-electric works from £7,523,928 to £8,467,735. A large portion of this —about £2,000,000— is represented by works, mainly at Arapuni, which had not at the end of the year come into operation, but which will gradually come in during the present year.

The first unit of the Waikaremoana Station came into operation shortly before the end of the year, but was not in for a sufficient time to give any very considerable increase in revenue. Nevertheless, the total revenue for the year shows an increase of 12-8 per cent, over that for last year, being now £516,127, as against £457,369 for the previous year. The peak load supplied amounts to 62,404 kilowatts, as compared with J 54,502 kilowatts last year. As for the previous year, a large amount of power had to be purchased from outside sources before Waikaremoana came into operation to supply all load offering on the Mangahao system, and, similarly, large amounts of jpower had to be purchased or generated by fuel plants in the Auckland District owing to the overloaded condition of the Horahora plant, brought about by the failure of the contractors to complete their work at Arapuni. The

percentage return on the whole of the capital in operation has increased from 4-99 to 5-62. The total capital invested, the annual revenue, and the percentage earned over a period of years are shown on the three accompanying graphs. Lake Coleridge. The year just past has again been fairly successful. The results can be summarized as follows : — £ Capital investment .. .. 1,581,262 Revenue .. .. .. .. 186,963 Operating-expenses .. .. .. 30,130 Balance .. .. .. £156,833 The balance has been used in paying interest charges and a 2-per-cent. depreciation charge, leaving a profit on the year's working of £50,374. This has been paid into the sinking fund. The scheme now has a depreciation reserve of £192,359, and a sinking fund of £112,334. The water-level in the lake has been well maintained during the year, and there has only been one interruption to supply of a serious nature. This was of one hour fifteen minutes' duration to the Christchurch supply, and was caused by flashovers on insulators during misty rain following a dry dusty spell. Inconvenience was minimized to some extent by the fact that the interruption was at half past five in the morning. It is pleasing to record that supply to the South Canterbury area has been much improved. The main items of construction have been in the direction of providing a further 7,500 kw. unit, -which will bring the capacity of the station up to 34,500 kw. This will be ready for operation at an early date. During the year the electrification of the Lyttelton-Christchurch Railway was completed in conjunction with the Railway Department, and electrical operation of traffic was commenced in February last. Horahora. This plant has not been so successful during the year. The financial position is summarized as follows : — £ Capital investment .. .. .. 1,142,346 Revenue .. .. .. .. 135,511 Operating-expenses .. .. .. 76,231 Balance .. .. .. £59,280 The balance has been used in paying interest and 2 per cent, depreciation, and the net result has been a loss on the year's operations of £15,291. The scheme now has a depreciation reserve of £103,187, a sinking fund of £52,164, and a reserve fund of £32,415, the last mentioned having been depleted by the necessity for making good the loss mentioned above and the replacement of assets destroyed by fire. The capital shown above and on which capital charges have to be paid includes £524,621 which has been spent on lines and substations which ultimately will be supplied by the Arapuni scheme, but which at present are supplied from Ilorahora and the other operating-stations connected to the system. The year has been a very difficult one from an operating point of view, as the plant has had to be kept running under heavy overload conditions. There has been heavy wear on the machines consequent on the large amount of silt travelling in the river, following the Arapuni diversion. A serious fire at the Ilorahora transformer and switch-house on the Ist September put the plant practically out of commission for some hours, but very strenuous efforts on repairs by the staff, together with

D.—l

XV

assistance afforded by other supply authorities, enabled the Department to keep all consumers supplied on the following day and thereafter, except for occasional short periods of overload causing low voltage in places. The steam-generating plant at Waihi and the Diesel generating plant at Penrose were both operated as required throughout the year. Waikakemoana. Supply from the small plant which was installed in 1923 for local supply and for construction purposes was continued during the year while the main plant was being completed. Operating-costs, including interest and depreciation on the plant in operation, amounted to £11,374 ; the revenue was £6,941, showing a loss of £4,433 on the year's operations. This makes a total accumulated loss of £23,190 on this plant, against which there is a depreciation reserve of £11,869. Although there was considerable delay in the delivery of certain items of the main plant from England, construction work was pushed ahead at a fast rate, and the first unit of the main, plant was supplying power at the end of January of this year. The second unit was completed and put on load early in July. The completion of these units should very materially assist the area which has previously been supplied by Mangahao, and eliminate the purchase of power from outside sources which has been necessary to meet all the demands made on the Department in this area. Surveys have been in hand during the year to enable designs to be completed for a further stage of this development, a portion of which must be put in hand before the two units now installed can be utilized to full advantage. Surveys are also in progress on a transmission-line to interconnect Waikaremoana with Arapuni. Mangahao. Although the rainfall on the Mangahao area was considerably better than in the previous year, the continued growth of load made the past year a difficult one, and considerable amounts of power had to be purchased to meet the demand. On this account the financial position is not as good as it might otherwise be. It can be summarized as follows : — £ Capital .. .. .. .. .. 2,416,713 Revenue .. .. .. . . .. 186,712 Operating-expenses .. .. .. .. 106,907 Balance . . .. .. .. £79,805 The balance has been sufficient to pay only 3 per cent, towards the interest charges for the year. £72,563 was spent on the purchase of power during the year, and is included in the operating-expenses shown above. Now that this station is interconnected with Waikaremoana it is expected that purchase of power will be unnecessary in future. Arapuni. There was an expenditure of £431,981 in connection with this scheme during the year, of which £163,148 is in connection with the headworks and power-station, £86,669 in connection with substations in various places, and £143,469 represents interest and miscellaneous capital charges on portions of the scheme not in operation. Of the total of £431,981, £160,676 has been transferred to the Horahora operating account. Work on the power-station, the erection of which was taken over from the contractors at the end of 1927, has been pushed on, and power was made available from the first 15,000 kw. unit on the 4th June, about seventeen months after the work was taken over. A second unit has just recently been completed, and it is hoped to have the third unit in operation before the end of the year.

Certain grave allegations as to the safety of the dam were made and given much publicity just prior to my taking over the portfolio of Public Works. I had most careful inquiries made into all the points raised, and found that there was no cause for apprehension whatever. The programme provided in the original contract called for completion of the power-station at practically the same time as the dam. Owing to the delay in completion of the power-house, which has been mentioned in this and former Statements, the full flow of the river has been running over the spillway-weir and the channel between that structure and the original river course for a period of over eighteen months. Considerable erosion has taken place in the old channel some 15 to 20 chains below the overflow-weir, and has been causing some concern. This tendency to erode will, of course, be considerably reduced as more and more water is taken through the power-house for power-generating purposes. Meanwhile, and as an emergency measure to reduce the flow passing over the waterfall where the damage has been occurring, the Department has arranged to put in two of the future penstock tunnels in advance of normal requirements, and to use them to bypass sufficient water to enable protective works to be put in on the overflow channel. Contracts have been let for the necessary pipes and nozzles, and the excavation of the tunnels is in hand. Three shifts are being worked in order to have the work completed at the earliest possible date. • Waitaki. Work on construction of this new scheme has been pushed on during the year. As is inevitable on a work of this magnitude, a vast amount of preparation work on housing workmen, collecting plant and machinery, has to be done before anything shows as part of the permanent asset. A branch railway has been built from Kurow to the works, and is being used to transport materials to the site. A section in the main river-bed has been enclosed in a coffer-dam, and at time of writing the shingle overlying the rock in this section has been excavated and a start is about to be made in pouring the first of the concrete in the main dam. The excavation at the site of the main power-station is in hand, and a start will shortly be made on the first sections of the actual building. Tenders have been accepted for practically the whole of the generating plant, and portions of it will begin to arrive on the site during the coming summer. Waipori. During the year negotiations. have been proceeding between the Department and the officials of the Dunedin City Council with a view to the purchase of the Council's power plant at Waipori. The city is faced with the expenditure- of very large sums in the next few years to provide additional power, whilst on completion of the Government station at Waitaki the Department will have power to sell which it is felt might be used to supply Dunedin and so obviate the necessity of a considerable portion of the additional capital at Waipori. There were also considerable advantages in the operation of two plants by one controlling authority. Local Electric Supply Authorities. The Department is to a considerable extent a partner with many of the local supply authorities in making power available to the actual consumers. Many of the supply authorities actually distribute the power generated by the Department, and all of them operate under licenses and regulations administered by the Department. The Government itself now has an investment of £8,467,735 in its hydroelectric developments, and local authorities obtaining their power wholly or in part from the Government have an investment of £11,534,318, whilst the others, who are independent of Government supply, have an investment of £6,088,424. On the whole, the supply authorities buying their power in bulk from the Department are in a better general financial position than are those operating on'their own account. Of the twenty-seven Power Boards purchasing power from the Government, only three had to resort to rates to augment their incomes, and raised a total of £8,056 by that means. Of the eleven Boards not using Government supply,

D.—l

XVII

five collected rates to a total value of £68,713 during the year. Representations have been made to me at various times that the Department should reduce the price charged for current, particularly to the smaller Power Boards operating in country areas. An examination of the accounts of the various Boards and also of the accounts of the Department indicates that as a general rule the local authorities' accounts are in a better financial position than is the Government electric-supply account. There is no question, also, biit that the rate at present charged the country Power Boards gives a considerably smaller return per kilowatt to the Department than does the somewhat lower rate charged the larger cities and Power Boards for much larger amounts of power. RIVER-IMPROVEMENTS AND LAND-PROTECTION WORKS. Wairoa River. —In this case only a small amount of work has been done, this consisting of an extension of the stone protection work on the foreshore of the Wairoa River. Waihou and Ohinemuri Rivers. —The heavy stop-bank construction work on the Lower Waihou River was practically completed during the year, the erection of several small flood-gates and other small miscellaneous items only remaining to be finished. As a,result of the heavy flood of July last year, rather extensive seepages showed in the Upper Waihou system of stop-banks, so that further strengthening and raising of the bank in places is required. This work, though heavy, is now being expeditiously gone on with, and with its conclusion the construction works involved in the scheme may then be regarded as completed. Taieri River. —The main stop-bank system has been completed. The pumpingstation for dewatering the plain is also complete, and the pumps have been satisfactorily tested. The main canal, \\ miles long, from the pumping-station to connect with the main system of drains on the plain is in hand. The Railway Department has completed the extension of 400 ft. to the Otokia Railway Bridge, and the old railway-embankment which it replaces is being removed. With the exception of some work required to the contour channel, the plain is now in the position of being able to receive full benefit from this protective scheme. HARBOURS. At Westport during the past year the Department has been considerably concerned over the persistent shoaling which took place on the bar during the earlier portion of the year. This has been dealt with by adopting an accelerated dredging programme, three dredges being in constant operation. Arrangements are now in hand, however, to extend the breakwaters, and it is anticipated that this will lessen the amount of dredging required. The protective works at Organs Island have been completed, and the harbour facilities generally have been well maintained. The recent earthquake did a considerable amount of damage to the wharves but this is well under repair. At Karamea the reconstruction of the training-wall is being steadily proceeded with. All preliminary work was completed, and a start has been made with the depositing of stone. The recent earthquake has considerably damaged the staging and some of the work already done, but efforts are being made to repair this and push ahead as speedily as possible. At Waikokopu a contract was let for the construction of a stone breakwater, and the contractor is making good progress, two miles and a half of tramway having been built, quarry opened up, and a quantity of stone placed in position. A number of wharves have been erected and small harbour improvements carried out in various parts of the Dominion, for which funds have been provided either in whole or part by the Government.

LIGHTHOUSES. During the past year the various aids to navigation round the coast of New Zealand have been added to by the installation of additional lighthouses and by the provision of apparatus for bringing some of the older installations up to date. A new automatic flashing light has been installed at the North Cape, and should be of great assistance to shipmasters, as it provides a definite turning-point to vessels navigating these northern waters. At Manukau Heads the older type of light has been replaced by an up-to-date automatic flashing-apparatus. The provision of a light between Cape Palliser and Castle Point to indicate the position of the Kahu Rocks has been urged by the Merchant Service Guild for some time past, and a lighthouse complete with a modern incandescent Dalen light has been built and is now in operation. This apparatus is operated automatically throughout, and only requires tending about twice a year. The existing light at Cape Egmont is not now suited for this locality, being a fixed light pure and simple, so that the necessary apparatus to convert it into a powerful revolving light has been procured and will be installed very shortly. At the entrance to Tory Channel a new automatic flashing light is being erected on the West Head and the existing oil-burning leading-beacons are being replaced by more modern acetylene outfits. Among the principal works proposed for the coming year are the transfer from Pencarrow to Baring Head and the modernizing of the old high-level light as well as the existing fog-signal, the conversion to automatic flashing of Godley Head and Moeraki Lighthouses, and the installation of a fog-signal at Taiaroa Heads. IRRIGATION AND WATER-SUPPLY. During the past year steady progress has been made with construction works on the Arrow, Hawkdun, and Teviot extension schemes. The erection of the pipe-line on the Arrow scheme is now well in hand, and it is hoped to supply the full area next season. The Hawkdun scheme is now completed, and a full service can be given. On the Teviot extension scheme work was completed, and portion of the area was supplied with water.

D.—l

During the year the existing schemes were maintained in good order. All lands requiring water were well served. The total area irrigated under all Government schemes was 38,255 acres, the number of irrigators being 335. Investigations on several small proposed schemes have been made, and surveys and foundation tests have been made at three possible dam-sites on the Upper Poolburn Stream, where a reservoir is required to supplement the Tela Valley scheme. The best site has now been selected and a start with the preliminary work authorized. The graph appearing on the previous page shows the growth of irrigation under Government schemes for the past ten years. ROAD-CONSTRUCTION. During the last financial year the construction and improvement of roads throughout the Dominion were actively prosecuted, with the result that many settlers who have been handicapped in the past for want of reasonable road access have now had that handicap removed, and vast improvement has also been effected to the already partially completed roads by way of widening and surfacing. The expenditure on the construction of roads and main highways reached the very large sum of £1,770,073, which is considerably in excess of any previous record. This figure appears very high, but I think that when consideration is given to the absolute necessity for good roads in the proper development of the country the expenditure will be found to be justified. A large portion of the expenditure mentioned was incurred on roads which were put in hand during the year for the purpose of easing the unemployment situation, a very large number of relief workers having been engaged on roadworks. Although in ordinary circumstances some of the roads so treated would not have been constructed for several years, care has been exercised in selecting only those roads which will be of benefit to existing settlement, or those likely to promote new settlement at an early date. In short, every effort has been made to utilize the services of relief workers as much as possible on reproductive works. Good use was also made of the funds set aside in the " Access to outlying districts " vote, considerable assistance having been given during the year to many of the farback settlers who have suffered from access difficulties for some time. The constitution of the special vote for " Backblock districts " has been so successful that I feel justified in asking Parliament to increase it for the present year. With regard to the automatic allocation of funds under the Roads vote, the factors upon which the allocation has been based were: Area, 5 per cent. ; population, 5 per cent. ; amount of general and special rates, 5 per cent. ; total mileage of roads in use apart from metalled or surfaced roads, 5 per cent. ; loans for roads, 5 per cent. ; estimated amount to complete all as metalled roads, 37f per cent. ; and value of undeveloped Crown and Native lands, 37|- per cent. The system in accordance with these factors has been in operation for several years, but as it was felt that it was not meeting requirements satisfactorily, in that it was definitely known that some districts were receiving a larger quota of the funds than their requirements over a period of years indicated as necessary,, and as a result others were receiving less than they otherwise would, the question was thoroughly gone into with a view to ascertaining whether an alteration in the factors would result in a fairer distribution of the vote. After careful investigation it was decided to amend the system by deleting " area " and " population," and adding the percentages from these factors to those for " total mileage of roads in use apart from metalled or surfaced roads " and " loans for roads," thereby increasing the allowance for those two factors to 10 per cent, in each case. In addition, the third factor was altered to allow for general rates only, in lieu of general and special, and unformed legal roads (i.e., paper roads) were deleted from the computation in the sixth factor, allowance being made only for those roads upon which some formation work had been carried out, or which will soon be brought into use. The factors in the new scheme are, therefore—Amount of general rates, 5 per cent.; total mileage of roads in use apart from metalled or surfaced roads, 10 per cent. ;

D.—l

XX

loans for roads, 10 per cent. ; estimated amount to complete all roads (apart from legal unformed roads) as metalled roads, 37-| per cent. ; and value of undeveloped Crown and Native land, 37| per cent. These alterations had the desired effect, and the amended system has been put into operation this year, it being confidently anticipated that the year's experience will prove the soundness of and justification for the alteration. The expenditure on the renewal of bridges was slightly more during the year than it was in 1927-28, with the result that many more old worn-out structures in various parts of the Dominion were replaced. The damage caused to roads generally by floods was considerably less, but, nevertheless, a fairly large sum was expended, chiefly on minor repairs.

PUBLIC WORKS DEPARTMENT: NET EXPENDITURE ON ROAD CONSTRUCTION INCLUDING MAIN HIGHWAYS FOR YEARS 1913-14 TO 1928-29.

PUBLIC BUILDINGS. At Wellington a new fire-alarm system was installed at the Public Works Store at Pipitea Point. Additions were made to the photographic gallery and steel windows provided in the composing and Hansard rooms of the Government Printing Office. At Wanganui Public Works Office extensive alterations were carried out. In the Taumarunui district a three-stalled brick motor-garage was erected at the Public Works Office. A landing reserve was provided and a departmental building erected at Taupo for the Taupo fisheries. At Whangarei alterations were made to the existing garage at the Public Works Office and necessary machinery installed. The capital expenditure on departmental buildings was £4,307. Courthouses. A building has been acquired at Whangarei and fitted up as a Courthouse. Extensive alterations and additions were made to the Hastings Courthouse. At Foxton a new building was erected. Repairs and renovations have been carried out to a number of Courthouses throughout the Dominion. The capital expenditure last year on Courthouses was £8,387.

Prison Buildings and Works. With the exception of extensions needed at Invercargill to meet the demand for separate accommodation of persons committed for Borstal treatment, the present building programme of the Prisons Department is nearing its close, the approaching completion of Mount Crawford Prison at Wellington and Paparua Prison at Christchurch practically marking a halt in the need of recent years for increased accommodation of all sentenced persons. Within the last few years the policy of drafting men to prison farms has assisted to relieve the congestion of city prisons, and has enabled the capital cost of accommodation to be kept at a minimum. Hence during the last few years the demands on Public Works Fund for prison buildings have been reducing, and for 1928-29 the expenditure was relatively low, being £12,572. The following briefly sets out what work has been carried out last year with that sum : — At Auckland Prison the conversion of the quarry plant was completed so as to meet the changed modern-highway demands for high-class graded metal. At Waikeria Borstal Institution and Reformatory capital erections were confined to erection of a third dairy to accommodate the increasing dairy herd of this productive farm. At New Plymouth Prison a baker's oven was installed, with the satisfactory results anticipated both from an expense-saving and a vocational point of view. Improvements were also made to the existing cell accommodation of that prison. At Mount Crawford Prison, Wellington, work had sufficiently progressed to enable all inmates to be transferred from the old Terrace Prison and is now in full occupation. With some little additional expenditure 011 complement workshops, garages, &c., this prison will require no further capital expenditure for some time. The programme of cottage-erections for officers' accommodation was much advanced and is now nearing completion. At Wi Tako Prison, Trentham, additional accommodation commenced in previous years was completed last year and is now sufficient to meet all anticipated demands. At this prison a commencement was made to lay a high-pressure water system from the Upper Hutt Borough supply. This will be completed in the current year. At Addington Women's Reformatory, Christchurch, the erection and equipping of a modern laundry was completed for carrying out Defence and Railway laundry - work. The Public Account saving to the State by this utilization of prison labour has already exceeded the total capital cost of construction on the laundry. At Paparua Prison, Christchurch, erection of exercise-yards was gone on with, following the completion of the buildings. These yards are now practically completed. The erection of washing and screening plant at this prison was completed, and is now, with the aid of a crusher transferred from Mangahao Hydro-electric Power Station, producing crushed and graded metal for local highways in the southern environs of Christchurch. The remainder of principal buildings and works of the Department was confined to the Invercargill Borstal Institution. This included erection of an additional story to one of the wings to meet the demand for more accommodation, erection of a garage for the farm motor-truck, and continuance of estuaryreclamation. Police-stations. The expenditure on police-stations for the year amounted to £6,925. New stations were erected at Normanby, Sumner, and Lumsden, and new offices at Hastings, Mount Albert, and Lower Hutt. A contract was let for approximately £5,000 for additions to the Auckland Central Police-station to provide muchneeded accommodation, and the work is now in progress.

Post and Telegraph Buildings. The need still exists at many places for new or additional accommodation for the conduct of post and telegraph business. During the year, however, satisfactory progress was made with the building programme. Notable works were the erection of a post-office building at Waverley, the making of extensive additions to the post-office buildings at Hawera and Waipukurau, and the erection of a large garage at Dunedin. At Napier the erection of a chief post-office building is well under way, and will be completed in 1930. At Dunedin the old chief post-office building has been demolished, and the site has been excavated in readiness for the erection of the new building. At Greymouth extensive alterations and additions are being made to the chief post-office building. Among other departmental buildings the erection of which is to be proceeded with in the near future are Courtenay Place (Wellington), High Street (Christchurch), and Upper Symonds Street (Auckland). Large additions will shortly be made to the post-office buildings at Nelson, Newton, Masterton, and Whangarei. During the year a number of sites have been acquired with a view to erecting thereon post-office buildings when required. The increase in the number of motor-vehicles in use in the Department has necessitated the provision of further garage accommodation. The practice is to erect garages at places at which suitable accommodation for renting is not available or at which the renting of accommodation would be unprofitable. In order to keep the expenditure on garages as low as possible, and to provide accommodation for motor-vehicles at places at which tradesmen are not available for the erection of garages, the Post and Telegraph Department is, by way of trial, having small movable garages constructed at a centre and forwarded in sections to the places at which they are required. The maintenance of post-office buildings and fittings involves considerable expenditure. Control of this expenditure was assumed by the Post and Telegraph. Department from the beginning of the financial year 1928-29. Previously such expenditure was controlled by the Public Works Department. During the year buildings were erected as follows : — Post-office buildings : Herekino, Hinds, Te Akau, Tokoroa, Waikaia, Waverley. The building at Tokoroa was erected by the local settlers, half the cost being borne by the Post and Telegraph Department. Garages : Dunedin, Featherston, Henderson (movable type), Lumsden (small shed converted), Papakura (additional), Tokomaru Bay,* Waipu (old stable converted), Waipukurau,* Waverley.* Increased or improved accommodation for departmental purposes has been provided at the following places : Ashburton, Ashhurst, Auckland (central telephone exchange, Wellesley Street), Avondale, Gore, Hanmer Springs, Hawera, Kaponga, Matamata, Milton, Mokauiti, Ohinewai, Papakura, Paparoa, Pembroke, Te Teko, Waikanae, Walton, Waipukurau, Wellington (Savings-bank Branch, Chief Post-office), Wellington (Radio). The following works are in progress : Greymouth —addition and alterations ; Mercer —new post-office building ; Napier —new chief post-office building ; Ohakune —garage and store, and accommodation for carrier-current telephone equipment; Rotorua —addition and alterations ; Shirley—new post-office building. The erection of new post-office buildings at the following places has been authorized : Courtenay Place (Wellington), Cust, New Lynn, Northcote, Dunedin, High Street (Christchurch), Palmerston (South). Additions and alterations at the following places have been authorized: Cromwell, Invercargill, Masterton, Nelson, Newton, Wairoa, Whangarei. On 17th June last a severe earthquake occurred in the Nelson, Westport, and Greymouth districts, causing extensive damage to the Nelson, Greymouth, and Westport Post-offices. So extensive was the damage at Westport that the building has had to be demolished, the Postal Department now carrying on its business at the Public Works office until a new building is erected.

Sites. A site for a post-office building was purchased at Grey Lynn, and sites for storage purposes at Invercargi.ll and Palmerston North. Additional land for the post-office site at Hastings was taken in March, 1928, under the Public Works Act. Agreement as to compensation has not yet been reached. The purchase has been authorized of a post-office site at Birkenhead, and storage sites at Dannevirke and Gisborne. A lease was entered into with the Railways Department for the use of an area of land at Newmarket, with buildings thereon. It is intended to use the buildings as workshops, &c. In the report for the year 1924-25 reference was made to an exchange of real estate between the Government and the Auckland City Council, under which the transfer to the Council of the Auckland East (Shortland Street) Post-office building and site was proposed. Owing to difficulties which subsequently arose, and on which agreement has not been reached, the exchange has not yet been effected. Miscellaneous. The separate wooden public telephone-cabinets which had been in use for a number of years outside the chief post-office building, Auckland, were replaced by two sets of cabinets constructed of bronze. At Dunedin excavation in connection with building operations on private land adjoining the automatic-telephone-exchange building made it imperative to strengthen the foundations of the exchange building. Underpinning in concrete down to floor-level of the adjacent excavation was found necessary. At Kurow, Lincoln, Little River, Waikari, and Woodlands the postal business was separated from the railway business, separate accommodation for the postoffice being provided in each case in the railway-station building. The cost of the necessary alterations to the railway-station premises was borne by the Post and Telegraph Department. In December the railway-station premises at Kurow, in. which the post-office was conducted, were destroyed by fire. Consideration is now being given to the question of erecting a separate post-office building. In the meantime the postoffice is accommodated in temporary premises. Extensive alterations were made to the accommodation occupied by the Savings-bank Branch of the Chief Post-office, Wellington, in order to relieve congestion in the public space and facilitate the transaction of business. Improved strong-room accommodation was provided in the General Post Office building. The net capital expenditure on Postal and Telegraph offices last year was £62,086. Mental Hospitals. Avondale : Extensive alterations and additions have been made to various buildings during the year, and renovations carried out as required. Wolf Home : The buildings have been repainted and a washhouse erected. Puhitahi: The following buildings, in wood and concrete, have been erected : Kitchen block, with dining-rooms, &c. ; lavatories ; dormitory for men's quarters ; artisans' quarters; calf-pens and. piggeries. In addition, brick and concrete stables, implement-shed, and boiler-house have been built. A temporary watersupply has been provided, with high stand and tanks and motor-pump. For the permanent supply a contract was let for carrying water from Patumahoe Springs ; the reservoir, with necessary 6 in. and 8 in. pipe-lines, has been completed. Electric supply has been laid on from the Franklin Power Board's reticulation. Tokanui: Artisans' quarters in wood have been completed during the year, and three brick villas for women are in course of erection and nearing completion. Porirua : The new Nurses' Home, containing over a hundred rooms, was completed, furniture and furnishings installed, and the laying-out of the grounds commenced. An incinerator and two garages were erected, additions have been made to a number of buildings, and renovations carried out as required. A new

D.—l

XXIV

system of ventilation has been installed in the women's portion of the main building, similar to that recently installed in the men's portion. The watersupply has been improved by raising the level of the lower dam, and all fire-hydrants have been overhauled and put in good order. Nelson and Stoke : Three large villas in brick and concrete are in course of erection ; also a new bakery, meat-shop, &c. Sunnyside : Extensive additions to the boiler-house are under construction, new boilers, &c., being provided together, with new chimney-stack, &c. Templeton : Villa No. 2, on the same lines as Villa No. 1, is in course of erection, very satisfactory progress having been made. Seacliff : A new laundry and kitchen block has been erected, and is ready for the installation of machinery and equipment. Additions to the Nurses' Home and a new Assistant Medical Officer's house are nearing completion. New piggeries have been erected, and extensive alterations, additions, and renovations have been carried out. The expenditure on mental hospitals last year amounted to £96,782. Health and Hospital Institutions. At Queen Mary Hospital, Hanmer, the contract for the erection of a new Nurses' Home is making good progress. A new brick boiler-house has been erected, and lavatory block No. 2 has been renovated. Extensive additions were made to the hospitals at Napier, Greymouth, and Gore, and the erection of a maternity hospital at Paeroa is well advanced. A new hospital in concrete was erected at Te Araroa. The capital expenditure on health and hospital institutions during last year was £19,637. The proposals this year provide for the erection of a new St. Helens Hospital at Christchurch, and the purchase of land at Auckland for extensions to St. Helens Hospital; also the purchase of land at Dunedin for a new maternity hospital, which it is proposed to erect to provide increased facilities for the teaching of obstetrics. Provision is made for completion of the massage block and Nurses' Home at Hanmer. Provision is also made for an ante-natal clinic at St. Helens Hospital, Wanganui, which is now nearing completion, and various additions to staff quarters at St. Helens Hospitals at Gisborne, Wanganui, and Invercargill. Extra accommodation is arranged for at Otaki Sanatorium, owing to the separation of the hospital from the sanatorium. Agricultural Buildings. The amount expended last year on capital works was £2,808, being practically the same as the previous year. The principal works carried out were new piggeries at Motuihi Island erected, electric light and power installed at Te Kauwhata Farm and Wallaceville Laboratory, and an implement-shed and hothouse erected for the seed-testing branches at Palmerston North. Education. For the year ended 31st March, 1929, the sum of £375,352 was spent on new school buildings, additions, sites, and teachers' residences. Of this amount, £247,348 was expended in connection with primary schools, the larger works including a new infant department at Meadowbank (Auckland), a new school at Awapuni (Gisborne), and separate secondary departments at Te Karaka and Wairoa (Hawke's Bay), and at Fairlie (Canterbury). Model schools were established in connection with the Auckland Training College. Additions to schools have been provided at Taumarunui, New Lynn, Papatoetoe, Ellerslie, Hikurangi, Morrinsville, and Otorohanga, in the Auckland Education District; at Mahora, Hawke's Bay ; and at Elmwood, Canterbury. The erection of numerous small schools in newly settled districts, and additions to existing schools, have also been undertaken, especially in those localities where two teachers were compelled to teach in one room.

While many of the old schools have been remodelled to provide up-to-date conditions, the Department, owing to lack of funds, has not been able during last year to carry out its intention to rebuild some of the obsolete city schools, and it is hoped that something in this direction can be done this year. A considerable building programme is being undertaken to provide accommodation for secondary-school pupils. During last year additions were erected at the Mount Albert Boys' Grammar School, the Hutt High School, and at the Wairarapa High School. A workshop building was completed at Marlborough High School, and additional dormitories at the Dannevirke High School Hostel. At the close of the year further additions were in course of erection at Mount Albert, Auckland, and at Dannevirke. A large sum was expended in the erection of buildings for the Massey Agricultural College, and further expenditure will be required in order to complete this institution. Additional accommodation and workshops have been added to several technical schools, and additions are in course of erection at Auckland, Hamilton, Palmerston North, and Christchurch. Applications are still being received for grants for the erection of open-air class-rooms, and these are being erected where the localities are considered suitable. Certain information is being collected regarding the children attending these schools, with a view to ascertaining whether, this type of building is more suitable to New Zealand conditions than the standard fresh-air class-room. The following table shows for the year ended 31st March, 1929, the amount expended by the Department on new buildings, additions, sites, and teachers' residences:— £ Primary schools .. .. .. .. .. .. .. 247,418 Secondary schools .. .. . . .. .. 44,382 Technical schools .. .. . . . . 23,281 Training colleges .. .. .. .. .. .. .. 2,223 Universities .. .. .. .. .. .. .. 1,564 Native schools .. .. .. .. .. .. .. 6,044 Special schools .. .. .. .. .. .. .. 12,277 Free kindergartens .. .. .. .. .. .. 967 Massey Agricultural College .. .. .. .. .. 32, 546 Canterbury Agricultural College .. .. .. .. .. 4,650 Total .. .. .. .. .. £375,352 TOURIST AND HEALTH RESORTS. The expenditure was £39,254, as against £36,673 for the previous year. The erection of a hostel at Milford Sound to accommodate sixty guests was completed, and was in use during last tourist season. It is provided with electric light and every modern convenience, and tourists will now spend longer visits to this beautiful scenic resort. A new engine for the steamer on Lake Te Anau was purchased and installed, and extensions to the Rotorua electrical system were completed. The large additions to the hostel at Waitomo were also finished. This building will now accommodate one hundred tourists. TELEGRAPH EXTENSION. The expenditure for the last financial year in extending and improving the telephone, telegraph, and wireless facilities throughout the Dominion amounted to £624,414. Of the works upon which capital expenditure was incurred during the year, the following were the more important: The installation of two carrier-current-telephone channels between Auckland and Hamilton ; the erection of new metallic circuits between Palmerston North and Wanganui, Te Aroha and Hamilton, Rotorua and Atiamuri, Gisborne and Morere, Carterton and Greytown, Blenheim and Seddon, Darfield and Coalgate, Christchurch and Leeston, Rangiora and Oxford,

Tokarahi and' Duntroon ; the laying of a submarine cable between Maraetai and Awaroa ; the installation of direct-dialling circuits between Wellington and Blenheim, Wellington and Masterton, Paekakariki and Wellington, and Palmerston North and Dannevirke, and the improvement and extension generally of toll facilities ; the installation of a universal-battery system in Palmerston North Tele-graph-office ; the opening of new exchanges at Wellsford, Towai, Waimamaku, Mangapai, Kirikopuni, and Tokanui; the installation in thirty-seven exchanges of additional switching equipment for 3,940 exclusive lines and 200 party lines ; the establishment of sixty-six new public call offices (coin-in-the-slot telephones) ; the laying of 2,772 chains of underground telephone-ducts and 10,160 chains of underground cable ; the erection of 5,260 chains of overhead cable ; the erection of 850 miles of pole-line and 8,270 miles of open wire ; and the connection of 12,119 new subscribers' stations. Some idea of the extensive network of lines interconnecting the various exchanges and telegraph-offices throughout the Dominion may be gauged from the fact that on the 31st March last there were approximately 380,000 poles in use, carrying over 62,602 miles of open wire. In addition, approximately 400,000 poles and over 495,000 miles of wire of all classes were in existence in telephone-exchange subscribers' lines. Notwithstanding the many important extensions that have been made to the system of electrical communications during the last few years, the necessity for additional facilities, particularly in the matter of telephone-lines, is just as real and just as urgent to-day as it was ten years ago. This condition is not peculiar to New Zealand —it is world-wide. In all the foremost telephone countries the difficulty is not to obtain the traffic, but to keep pace with it in the matter of providing additional circuits. Telephone service is now so intimately connected with the business and social life of the community that no sooner is telephone communication provided between cities and towns widely separated (and not previously interconnected) than there is a demand for additional circuits to relieve the traffic congestion. A striking example in that respect is the inter-Island telephone service. Two years ago telephonic communication between Wellington and Christchurch was impossible. To-day, as a result of providing an efficient means of communication between the two cities, it is necessary to double the capacity of the South Island land-line section of the Wellington-Christchurch circuit in order to relieve the congestion of traffic. In the matter of extending and improving the long-distance telephone facilities throughout the Dominion the most important development during the year was the introduction of the system known as carrier-current telephony. The carriercurrent system consists briefly in the application of radio-frequency methods to existing telephone circuits, thus enabling additional telephone speech channels to be obtained without increasing the existing wires. The new process is in reality a system of wireless communication in which the electro-magnetic waves, instead of being broadcast, are directed along the metallic conductors of the wires already erected without interfering with the purposes for which such wires were originally designed. The most important feature of the new system from the practical point of view is the large saving it effects in installation and line-maintenance costs. In addition, the system provides an excellent speaking-circuit, and as compared with the well-known metallic wire circuit it gives louder speech and is less subject to the interfering noises caused by power lines and similar disturbing influences. The initial installation in New Zealand of carrier-current equipment comprises three single-channel systems for use between Auckland and Hamilton ; a three-channel system for use between Hamilton and Palmerston North, which will provide a single channel between Hamilton and Palmerston North and two channels between Wellington and Auckland ; and a single-channel system to supplement the South Island land-line section of the Wellington-Christchurch telephone circuit. At the present time two channels of the Auckland-Hamilton system are in operation, and it is hoped to have the other systems working at an early date. When the three systems mentioned are in use, and the equipment is properly tuned in, high-grade and efficient telephone speech channels will be available at any hour of the day or night between Auckland and Dunedin, and between the principal centres within

D.-l

XXVII

those limits. In addition, much of the congestion which now exists 011 the longdistance lines within each of the two Islands will be considerably relieved. As soon as the above-mentioned systems are in operation consideration will be given to the question of installing carrier systems between other centres. A great deal of work was also carried out during the year in the direction of extending and improving the facilities for short-haul traffic. In almost every part of the Dominion some facility was provided for the purpose of relieving congestion of traffic or for giving service to some backblocks settlers that had not previously enjoyed any of the privileges or conveniences of the telephone. In addition, the speech efficiency of toll circuits and the physical condition of the lines were considerably improved by the carrying-out of many reconstruction works. These works included the renewal of pole-lines, the replacing or respacing of poles, the strengthening of existing poles, the regulation of wires, the rearranging of transpositions, the substitution of copper for iron wires, and the re-erection of circuits 011 the twist system. The steady expansion and growth of the local-exchange systems which has characterized telephone development in New Zealand during recent years was continued during 1928, the number of new connections installed being 12,119, as compared with an average of 12,112 per year during the preceding five years. The total number of telephone connections with departmental exchanges at the 31st March was 147,936, the number of telephones connected with toll stations and non-departmental stations 4,605, making a total of 152,541, which represents over ten telephones per hundred of the population, a telephone density exceeded only by the United States and Canada. A feature of last year's development in telephone-exchange systems was the large number of intercommunicating and extension telephones installed, the rate of increase being 7-7 per cent., as compared with 4-9 per cent, in the case of main stations. This was due to a large extent to the increased number of intercommunicating systems installed in business houses. The local intercommunicating system in most popular demand was the key-box interphone type, large numbers of which were installed in business establishments where the requirements in intercommunicating facilities did not exceed twenty positions. Next in order of demand were private branch exchanges of the full automatic type with capacities varying from twenty extension stations upwards. The latest development in the automatic-telephone industry is the manufacture of a small type of automatic exchange suitable for rural communities and capable of giving a twenty-four-hour service. One of such systems has been obtained by the Department, and will shortly-be installed in a suitable rural locality with a view to testing out its suitability in actual practice for the exacting conditions that prevail in rural exchange areas in New Zealand, and where a twenty - four - hour service under manual conditions would be economically prohibitive. Should the trial prove successful and the actual costs be reasonably low, the question of installing twenty-four-hour-service automatic exchanges in rural communities will be fully investigated. For economic reasons, however, the development of such a policy would have to proceed gradually, as a large capital expenditure would be involved. The Christchurch Telephone Exchange, to which over 11,000 stations are connected, is one of the largest in New Zealand to be converted to full automatic operation, and will increase by approximately 14 per cent, the number of automatic telephones in use in the Dominion. The conversion to automatic working would have taken place many months ago had not there been some unfortunate delays in the delivery of the equipment. Notwithstanding these delays, however, the actual time occupied in the work of installation compares favourably with that for similar exchanges of like capacity in this and other countries where machine switching methods have been introduced. With practically all the essential equipment now in sight, an intensive effort is being made to hasten completion of the work, additional skilled labour from other parts of the Dominion having been concentrated at Christchurch to assist in the construction of the internal switching

v—D. 1.

XXVIII

system, as well as in the installation of subscribers' telephones and subsidiary apparatus. If the outstanding items of equipment for subscribers' stations come to hand according to schedule time, as is confidently expected, the whole of the Christchurch metropolitan area will be completed and converted to automatic working in a few months. One indirect advantage arising from the delay that has occurred is that the Christchurch area, being the last of the large centres to receive full automatic treatment, will have the benefit of a number of the very latest developments in machine switching equipment. As soon as the cut-over takes place attention will be directed to the installation of a further 2,000-line extension, so that no unnecessary delay will arise in meeting the growth that is expected to follow the introduction of automatic methods. WORKS FOE DEFENCE DEPARTMENT. The mobilization base and training-camp at Waikato Camp, Ngaruawahia, is practically completed. The small-arms-ammunition magazine, ordnance workshops, vehicle-shed, forage-store, and other miscellaneous small buildings—all of which were under construction at date of last Statement —have been finished. A bathhouse, drying-room, three magazines (high explosive), coal-store, and hospital building have been erected, various facilities of a minor nature provided, noxious weeds and scrub removed, and the area generally improved. On the erection of the laboratory (under construction) and the clearing and grassing of a scrubcovered area the camp will be complete. At Trentham Camp the water-supply system has been connected to the Upper Hutt water-supply. The camp buildings, roads, and other services have been maintained. Burnham Camp has been generally maintained, and a concrete strong-room and Ordnance workshops erected. Various additions and improvements to fortifications, drill - halls, and miscellaneous buildings throughout New Zealand have been carried out and the buildings maintained. Very considerable progress has been made with the development of the New Zealand Air Force Base, Hobsonville, Auckland. The area has been cleared of trees and hedges, and two houses sold for removal. The landing-ground has been levelled, rolled, and sown in grass. A large land-plane hangar in reinforced concrete, with electrically-operated doors, workshops, and appointments, has been erected. A residence for the Officer Commanding and five houses for married airmen have been completed, while a sixth is under construction. A transport shed (for motor-vehicles), switchhut (for power lines), small boat-house, control-tower, and meteorological hut and base office have been erected. A sufficient water - supply was found by boring, and a water - tower, with pump-house and pumping plant, has been completed. The seaplane apron, involving considerable excavation, filling, and a stone sea-wall, is complete except for surfacing. The reinforced-concrete slipway (40 ft. in width and 290 ft. long) from the apron seawards is under construction, while the jetty (approximately 300 ft. in length) for handling stores and launches is nearing completion. Extensive accommodation for seaplanes, consisting of marine store, two large hangars, aircraft-repair shop, engine-repair shop, plumber's and blacksmith's shops, dope-shop, and offices, is required on the apron, and will be provided in one large reinforced-concrete building, work on which is well under way. An access road to land-plane hangar, office, and seaplane area has been completed. Extensive surface drainage, sewer - drains, septic tanks, waterreticulation, and underground power and telephone lines are proceeding as the base develops. MECHANICAL APPARATUS. The prosecution of the Tawa Flat Railway Deviation and other railway works has occasioned the purchase of numerous items of plant, while hydroelectric and main-highways construction has also involved certain important new purchases.

D.—l

XXIX

The efficient repair and maintenance of existing plant, which lias been assisted by the better organization of the staff in the held, has resulted in keeping down purchases of replacements to a minimum. Major items of plant purchased during the year include one steam crane, ten air-compressors, two stone-crushers, six air-receivers, four air-operated shovels, four motor generator sets, thirteen electric locomotives, two petrol-locomotives, four cement-guns, six concrete-mixers, seven petrol-engines, seven electric motors, seven pumps, six ventilatirig-fans, two winches, one electric lift, sixteen machine tools, eleven pneumatic mine-hoists, three welding plants, one motor grader, thirty-six motor-cars, thirty motor-trucks, and numerous other items of mechanical plant. This detailed list does not include the special items of plant which were purchased for main-highway work, and which are itemized in the special report of the Main Highways Board. STAFF. It is with sincere regret that 1 have to record that a number of officers of the Department died during the year. Mr. J. W. Swaney, Power-house Superintendent, Arapuni, died suddenly of heart-failure, having worked a full day on the day of his death. Mr. G. H. Hill, Overseer, Whangarei, died of heart-trouble after an illness of four months. Mr. W. H. Boys, Chief Clerk, Gisborne, died suddenly, having worked until the day of his death. Mr. T. J. Kiley,' Overseer, Kotemaori, died after an illness of three months. Mr. S. C. Collinge, fifth operator, Mangahao, died following an operation for appendicitis; and Mr. J. P. Good, cadet, Head Office, died of septicaemia after one week's illness. The following officers retired 011 superannuation : Messrs. C. H. Williams, Road Engineer, Wanganui; B. Bold, Land Purchase Officer, Head Office ; and G. Brown, Draughtsman, Wellington District Office. CONCLUSION. In conclusion, I wish to acknowledge, with thanks, the loyal support and assistance I have received from all members of my staff. The Department has been called upon to work at exceedingly high pressure. The large increase in the number of men employed and the vigorous prosecution of all the works in hand represent increased work for the permanent staff. The fact that practically no additions to the staff have been asked for, notwithstanding the heavy programme in hand, gives cause for congratulation, and is an indication that each officer from the highest to the lowest is carrying his portion of the load. As appendices to this Statement honourable members will find full details of the principal works carried out by the Department in the reports of the Engineer-in-Chief, Government Architect, Chief Electrical Engineer, and Main Highways Board respectively.

North Auckland Main Trunk Railway. Rangiahua Section (24 m. 25 eh. to 38 m. 34 ch.). —The construction of this extension of the North Auckland Main Trunk Railway has been continued under the most difficult conditions, due to the unstable nature of the country. A certain amount of trouble was anticipated with slips in the first 6 m. of the section, as surface indications pointed in that direction, but it was expected that the remaining Bm. would be reasonably stable. This has not been the case, and extensive slips have developed in all cuttings, often extending chains uphill, and a large number of banks have slumped away, carrying the foundation country away with them. The original formation was completed during the year to 38 m. 10 ch., but so serious have been the slips that it has been necessary to deviate the line to a new centre-line over a total length of 2| m. Involved in the construction of the line are over 5 m. of main-highway deviations, and owing to the slippy nature of the country it has been necessary to keep this work as light as possible by the use of short grades and vertical curves. The whole of the earthwork on these deviations has been done and sufficient metal placed to keep the road open for traffic. Permanent-way has been laid to 33 m. 36 ch., of which 3 m. 36 ch. was done during the current year. A total of sixty-four culverts have been placed, varying from 10 ft. diameter down to 12 in. Contracts have been let for the erection of station buildings and four platelayers' cottages at Waihou Station at 34 m. 9 ch. A quarry has been opened up, served by a railway-track 1J m. long joining the main line at 25 m. 16 ch. The installation of bins, crushers, engine-house, and plant is now practically completed, and crushing of ballast will commence immediately. It is hoped to sell considerable quantities of from this plant to local bodies, and also to supply metal for main-highways construction and maintenance for. road making purposes. Considerable work has been done during the year in stabilizing the embankments by means of large stone drains and small drainage-tunnels filled, with stone. In the slipped cuttings the only thing to do is to keep taking away the material until the toe can be held with a stone wall. This sort of work upsets the whole original estimate of cost; indeed, it is humanly impossible to predict what the work will cost in this type of country. Steam-shovels have been used constantly in clearing slips, and without these it would be impossible to get the line open. Extensive willow-planting is being done in the broken country in order to assist in holding the ground against future slips. Kiritcopuni Section (107 m. 0 ch. to 121 m. 0 ch.). —This section was handed over to the Railway Department on the 15th May, 1928, and during this year the formation, bridging, and metalling of the Paradise access road was completed. Tauraroa Quarry. This quarry, which has now been in operation for twelve years, and has a total output of 560,000 cub. yd, of crushed metal and 22,000 cub. yd. of spalls, has been under continuous operation during the year, the output being 87,641 cub. yd. of metal. This metal has been used principally on the Dargaville Branch Railway, on the Oakleigh-Waipu Road, and on the Auckland-Maungaturoto Main Highway, these works being in the hands of the Public Works Department. In addition, considerable quantities have been sold to Rodney, Hobson, Otamatea, Mangonui, and Bay of Islands Counties, to the Borough of Dargaville, and the Kamo Town Board. It is pleasing to note that very little time has been lost through mechanical breakdowns, and by careful management 2| in. metal has now been made saleable f.o.r. Tauraroa at 4s. 6d. a cubic yard. A heavy programme is anticipated for the coming year in ballast for the Dargaville Branch Railway, and the various grades of road-metal for the Auckland-Maungaturoto Main Highway. Dargaville Branch Railway. During the year the construction of the Dargaville Branch Railway has advanced rapidly. A few difficulties have been encountered owing to the river-flats not being sufficiently strong to carry enbankments. As the embankment sinks into the ground, there is a corresponding upheaval clear of the bank, and this condition is usually cured by spreading the weight of the embankment by the addition of " berms " outside the bank proper. A very large slip on the banks of the Wairoa River at 10 m. 70 ch., which has given trouble for years, is now being dealt with by trenching through it to a depth of 22 ft. into sandstone and filling this trench with stone ; this trench crosses the toe of the slip and will have outlet drains leading to the river. Generally the formation is of a light nature, and by the use of maximum grades and curves heavy work has been avoided where possible. Despite these precautions, several slight deviations of the line had to be made to avoid country which opened up badly. A feature in the construction of the railway has been the great advantage of the proximity of the Northern Wairoa River. Transportation of material has in consequence been a very simple matter. Steam-shovels, drag-line, and locomotives have been loaded on to barges using their own power, towed to new locations, and then unloaded in the same manner. Formation earthwork has been put in hand from 0 m. to 15 m. 60 ch., and, with the exception of bridge approaches at 1 m. 19 ch., 4m. 35 ch., and 7 m. 0 ch.., has been completed as far as 7 m. Formation requires widening in several places between 7 m. 12 ch. and 9 m. 40 ch. and is complete between 9 m. 50 ch. and 10 m. Tangowahine and Wharau station-yards are under construction.

Four steam-shovels have been in use on excavations, and a drag-line has done very useful work, including 3 m. of heavy ditching through the Opiako Swamp. The railway-formation has necessitated the relocation of the Dargaville-Whangarei Main Highway over a distance of approximately 2 m., and the construction of this new roading is well advanced. A total length of 13 m. of fencing has been completed. Culverting is well in hand, and a total of forty-five have been built during the year, ranging from 4 ft. arches to 12 in. pipes. Owing to lack of bearing-power in foundations, nine of these have required driven-pile foundations. Bridging has proceeded as far as the supply of hardwood piles will allow, and a total length of 330 ft. has been completed. Platelaying has kept pace with the completion of formation, and rails are now laid to 6 m. 70 ch. Ballasting has been carried as far as 4 m., the stone being obtained from the Department's quarry at Tauraroa. Pukehuia is the main encampment and distributing centre for the works, but it has been necessary to build a considerable new encampment at Tangowahine and a lesser one at 14 m. At the former place twenty-eight four-roomed married men's quarters, and eighty single men's huts have been erected, with the usual cookhouse, bathhouses, drainage, and water-services. These buildings were transferred from Pukehuia, as were also the nine married men's quarters and twenty-four single men's huts erected at 14 m. Three launches and six barges have been in constant use transporting men and materials. The telephone-line is in hand, poles being erected as far as 12 m., and the wires to Tangowahine at 10 m. Auckland-Westfield Deviation. This double-track deviation will connect the new Auckland Railway-station with the existing main south line at Westfield Railway-station, and the portion from the southern end of the new stationyard in Auckland to Westfield, a length of 8 m. 70 ch., is being constructed by the Public Works Department. Substantial progress has been made during the year, and the completion of the work is now in sight. The men are now being concentrated into the central camp at Purewa Tunnel, and the outer encampments dismantled and huts transferred to other jobs. Earthworks are complete and trimmed, with the exception of a small earthwork job at Purewa station-yard due to an alteration in alignment. The long embankment across Hobson Bay has not shown any appreciable loss of height, but there has been a minor subsidence in the bank across Orakei basin, and this is being brought up to grade with stripping from the Railway Department's ballast-pit. The portals of the Purewa Tunnel have been built, the floor has been cleaned out, and a clean stone-spall foundation laid with central pipe-drainage system. This central drain has been continued through the approach cuttings, with adequate cross-drains filled with coarse scoria. A large slip at the south portal gave trouble, but after cleaning out the toe with a steam-shovel a heavy stone wall was built and this has held the country. The rock-cutting from 6 m. 60 ch. to 7 m. 14 ch. has been widened to the full width of the reserve and all the stone used. A crushing plant has been in operation and 8,000 cub. yd. of metal and chips produced for concrete-work for ballasting the tunnel and for metalling approach roads. For the pitching of embankments on the railway and Waterfront Road 22,600 cub. yd. of heavy rock have been quarried, and transported by time-table service over temporary lines and newly laid permanent-way. The heavy bridging programme on the line is now practically completed. Three overbridges 40 ft. wide have been completed, also two 22 ft. wide and one 30 ft. wide, and all are now in use. The culverts over the mud-fiats, 9 m. 40 ch. to 9 m. 65 ch., all on pile foundations, have been finished, completing the culvert programme. Platelaying and ballasting have been in hand by the gangs from the Railway Department, and the left-hand track is now completed throughout and ballasted. Two miles of the right-hand track are laid, also the Marama and Panmure station-yards. The six station buildings have been erected by contract, and there only remains a small amount of drainage work and the installation of permanent water-supply. Platforms are being built of 6 ft. lengths of precast concrete, and all are now finished except the right-hand side of Orakei and Sylvia Park platforms. East Coast Main Trunk Railway—Waihi Eastwards. During the year the length of this railway between Tauranga and Taneatua, a distance of 59 m., was completed and handed over to the Railway Department for operation. Regular passenger and goods traffic was maintained on the line until the handing-over. Te Maunga, Te Puke, Paengaroa, Pongakawa, Otamarakau, and Matata Sections (41 m. 5 ch. to 79 m. 16 ch.).—The sidings into the Te Puke and Matata quarries were pulled up and rails sent to the Rotorua-Taupo Railway. All huts that were in reasonably good condition were also sent to Rotorua. During July and August the output from Te Puke quarry was 4,432 cub. yd. of metal, 1,223 cub. yd. of screenings, and 20 cub. yd. of spalls, and from Matata quarry 2,803 cub. yd. of metal. Extensions were made to the stockyards at Te. Puke and Papamoa. General maintenance was carried out until the line was handed over to the Railway Department on the 2nd September. Rangitaiki, Awakeri, and Taneatua Sections (79 m. 16 ch. to 100 m. 5 ch.). —The centre span of the Whakatane Bridge was widened to make a passing-place for motor traffic. The cattle-yards at Awakeri were extended for stock. All huts were pulled down and transferred to the Rotorua-Taupo Railway. General maintenance was attended to until the 2nd September, when the line was handed over.

Mount Workshops.—lso tons of steel was fabricated into girders for the Auckland-Westfield Railway, and 160 tons for the Waikare Bridge on the Napier-Wairoa line. The Te Puke quarry plant was overhauled, boiler retubed, and 150 elevator buckets made, and the whole transferred to Dunedin. Ten locomotives were overhauled, and nine of these sent to other districts. One locomotive was dismantled. Rolling-stock repairs were attended to, seven passenger-cars, three vans, and 261 wagons being overhauled and repaired. Rotorua-Taupo Railway. On the completion of the East Coast Main Trunk Railway men and materials were transferred to Rotorua, and a start made on the construction of the Rotorua-Taupo Railway. Erection of hutments commenced on the 10th July, 1928, and construction work was continued until the 18th March, 1929, when instructions w'ere received to close down the works and transfer men and plant to the Gisborne-Wairoa Railway. Two stores were erected—one at Rotorua and one at 7m. 131 double huts, 219 single huts, and 171 washhouses were transferred from the East Coast line and erected between 3m. and Bm. The store at 7m. and the best of the huts were dismantled and transferred to the Wairoa-Gisborne line after the works closed down. Hemo Section (0 m. to 3 m. 60 ch.). —Clearing, culverting main-road deviations, and formation were put in hand, but not much has been done. Ohinewai Section (3 m. 60 ch. to 7 m. 20 ch.).—Work was put in hand over the whole of this section. Service roads were formed, and nine temporary bridges erected to give access to cuttings. Two miles of formation in all have been completed, and 1,161 ft. of culverting laid, varying from 30 in. to 12 in. diameter. Pareheru Section (7 m. 20 ch. to 8 m. 40 ch.). —The whole of the section was cleared and five cuttings opened up. 229 ft. of culverting was installed. Gisborne-Napibr Railway. Putorino Section (10 m. 56 ch. to 37 m. 35 eh. ; length, 26 m. 59 ch.).—This section adjoins the opened line at Eskdale, and as far as Tutira the section has been open for goods and passenger traffi 0 for the whole of the year, and for several months traffic facilities have been extended to Matahoura Station. The year's work generally has comprised completion of the earthwork to Putorino ; the completion of the Matahoura Viaduct, Sandy Creek Bridge, and subway at 34 m. 10 ch. ; the laying of permanent track to Putorino Station ; and the ballasting of the whole line up to the Matahoura Viaduct. The formation is practically complete throughout the section with the exception of cleaning up and widening certain portions, and muck-trains have been employed completing narrow cuttings and filling along narrow banks. After the completion of the Matahoura Viaduct the cutting on the north side was completed and the material delivered to the embankment on the south side, the permanent-way in the meantime being carried on a trestle over the filling. The cuttings between Matahoura Viaduct and Putorino have also been completed during the year, extra shifts being worked at any point where delay in the progress of the rail-head was likely. All road-deviations in connection with the railway have been completed and metalled, and the access road to Putorino station-yard has also been completed and is in use. A grade-elimination proposal for the highway crossing the railway at 32 m. 44 ch. has been prepared, and the work of forming the approaches and erecting the overbridge is in hand. The fencing on this section is now practically complete, 124 ch. of fencing having been erected during the year. Five pipe culverts and one 4 ft. and one 6 ft. arched culverts were constructed and a retainingwall at 20 m. 6 ch. built during the year. At the Waikoau Viaduct, at 26 m. 60 ch. the footways, inspection platform, and wind-screen have been completed and the whole structure painted throughout. The Sandy Creek Bridge, at 29 m. 10 ch., consisting of three 60 ft. spans on steel trestles and concrete foundations, was completed and painted. The construction of the Matahoura Viaduct, at 33 m. 42 ch., consisting of two 60 ft., two 40 ft., and one 250 ft. span on steel trestles, with concrete foundations and concrete abutments, was the most important bridge-work of the year. It stands 208 ft. above the level of the stream and is very similar to the recently erected Waikoau Viaduct, so that the staging and cableway used for the former was dismantled and worked in very satisfactorily for the Matahoura. The erection of the steelwork proceeded without a hitch, and the work throughout was carried out efficiently and in quick time. The structure has now been painted and is complete except for guard-rails, while the workers' accommodation and most of the equipment has been moved ahead to the Waikare Viaduct, at 38 m. 15 ch. The concrete-work for subway at 34 m. 10 ch. was completed early in the year, and traffic was carried over a temporary trestle until the steel arrived a few months ago. This has now been erected and the work is practically complete. Permanent-way has been laid to the end of the section, at 37 m. 35 ch., 4 m. having been laid during the year, and sidings have been completed at Matahoura station and are in hand in Putorino yard. Platelaying is now proceeding northward to Waikare Viaduct to facilitate delivery of steel to that work. The line is completely ballasted to Tutira Station, at 28 m. 5 ch., and partially to the end of the section, approximately 20,000 cub. yd. of ballast being placed during the year.

D.—l

At Tutira stktion-yard (28 in. 5 ch.) tlie platelayers' cottages were completed, latrines, shelter-sheds, passenger-platform, and loading-bank, and 6,000-gallon vat were erected, and a good water-supply was provided. At Matahoura Station (32 m. 36 ch.) a shelter-shed and loading-bank have been erected, and temporary stockyards were built to deal with the present traffic requirements. Four platelayers' cottages are in hand at Putorino station-yard, (at 37 m. 20 ch.), while the goods-shed is practically completed. The Department's sawmill at Makomakojhas cut 870,206 sup. ft. of timber, most of which has been used on the Putorino and Wairoa sections. Regular trains have connected with the Railway Department's services to Eskdale, and good use has been made of the service by the settlers in the neighbourhood, both for goods and passenger traffic. Wairoa Section (37 m. 35 ch. to 70 m. 67 ch. ; length, 33 m. 32 ch.). —The works which have received most attention on this section comprise the heavy earthwork, tunnels, and bridges. The formation on this section is heavy, and, in addition to hand gangs and scoop teams, ten steam-shovels have been employed throughout the year, with their attendant locomotives and trucks, the leads in some places being over a mile. This work is well in hand, and will be completed in ample time to enable the platelaying to proceed as soon as the larger tunnels and bridges are finished. The northern portal of the Kotemaori Tunnel, at 42 m. 15 ch.—4-2 m. 56 ch., has been erected, and the bottom heading has been driven 6f ch. back to 42 m. 49 ch. The driving is rather wet, but the country is quite sound, being a soft sandstone, and indications point to better conditions when enlarging the heading. Pumping and ventilation machines have been installed, and the concrete layout is complete. The Chimney Creek Tunnel No. 1, at 46 m. 25 ch., 15 ch. in length, was completed in February of this year, and Chimney Creek Tunnel No. 2, at 47 m. 9 ch., 14J ch. in length, was completed in October last. The formation of road-deviation at 44 m. 79 ch. has been completed, and at 47 m. 67 ch. to 48 m. 8 ch. the formation and metalling is finished and a start has been made with the overbridge. In the Mohaka Tunnel, at 53 m. 2 ch., bad conditions generally have been experienced, and, although conditions have improved during the last six months, the tunnel is still very wet and rotten in patches, and a third shift has been started to speed up construction. A total of 16J ch. has been completed. The Waihua Tunnel, at 60 m. 70 ch., 14-07 ch. long, was completed in November last, including both portals. Several slips occurred at the south portal, but these are all practically cleaned up. Between 55 m. 45 ch. and 65 m. 25 ch. the railway fouls the road in a number of places, and several deviations to avoid this and eliminate crossings have been put in hand. The largest of these, 55 m. 43 ch. to 56 m. 53 ch., is almost completed, and metalling is in hand. Creek-diversions have been excavated at 52 m. 37 ch. and between 62 m. and 64 m., several of those between the latter chainages having been carried out by means of scoop teams. The culverts and water-drives throughout the section are well in hand, approximately twenty culverts and waterdrives having been put in during the period, and the balance will be completed in ample time to synchronize with the early completion of the formation. Approximately 400 ch. of fencing has been erected. The Waikare Viaduct, at 38 m. 15 ch., consisting of five 50 ft., one 60 ft., and three 100 ft. spans on steel trestles with concrete foundations, was commenced just after Christmas, and rapid progress has been made. The rail-level on this viaduct is 250 ft. above river-level. The concrete abutments A and F and concrete piers B and B1 are complete. The excavation of pier Eis complete, and that of Pier Cis well in hand. The approach trestle to the viaduct has been erected, and the cableway for the erection of the steel will be complete in the very near future. Extensive investigations have been made and bores put down to determine the best type of foundation for the Mohaka Viaduct, which will be tlie largest and most imposing of these viaducts, and an early start will be made with these foundations. The Wairoa River Bridge, at 68 m. 59 ch., consisting of one 107 ft. 6 in., two 106 ft. 3 in., and two 15 ft. 2 in. spans, is nearing completion. The six cylinders which form the river piers are practically complete, and the pile pier on the north bank is completed and a start has been made with the erection of the steel superstructure. A good deal of trouble has been experienced on this work with floods, and at one time a part of the temporary staging was carried away. The programme generally from the Wairoa end is to prepare all works from Wairoa River to Waihua River for platelaying, so that this work can proceed as soon as the Wairoa River Bridge is completed. The light formation from 66 m. to 69 m. is nearly completed, and good progress should then be made with the platelaying. A temporary hold-up may be experienced at the Waihua River Bridge, which has not yet been commenced, but after that everything should be complete to the Mohaka Tunnel. This latter work is well under way, and should by that time be nearly completed, so that track may be continued to the Maungaturanga Viaduct. Owing to the additional men employed on this work, especially over the latter half of the period, additional workmen's accommodation has been necessary, and this has been provided partly by the transfer of some of the huts from the Waikaremoana hydro works and partly by the building of some additional cottages.

Stratford Main Trunk Railway—East End. Matiere Section (0 m. to 10 m.). —This section is practically finished, and the work of the year included general maintenance and a small amount of construction to complete station-yard facilities and private crossings. Ohura Section (10 m. 0 ch. to 19 m. 10 ch.). —The section is now practically .completed. Ohura station-yard was finished during the year with the erection of the station buildings, stationmaster's house, engine-shed, ashpit, loading-bank, and latrines. Five platelayers' cottages were built, and a water-supply installed, including dam, 10,000 ft. 4 in. pipe, 6,000-gallon water-vat, 2,000-gallon feed-vat, and 2,000-gallon washout vat. Passenger-, goods-, and work-train services were maintained on this and Matiere section. Tokirima Section (19 m. 10 ch. to 29 m. 70 ch.). —Activities during the year have been concentrated on this section, and formation of the whole length has been vigorously pushed ahead. The formation is fairly heavy, including considerable road-access works and road-deviations. Two station-yards are included in the length, but the really heavy expenditure is in the construction of six tunnels aggregating a length just over 1J m. No. 1 tunnel, at 19 m. 48 ch. (length, 170 yd.), has been completed. No. 2 tunnel, at 20 m. 54- ch. (length, 170 yd.), is also completed. No. 3 tunnel, at 23 m. 60 ch. (length, 488 yd.) : Bottom drive has been completed, the north end portal built, and lining commenced. No. 4 tunnel, at 24 m. 38 ch. (length, 61 yd.) : Bottom drive is complete. No. 5 tunnel, at 25 m.., is 732 yd. long. At the north end the portal is in place, the bottom drive is in 149 yd., and lining completed for 44 yd. At the south end very heavy ground necessitated the concreting of the floor of the tunnel and the use of lining 30 in. thick. It is anticipated that better country will soon be reached and the work speeded up. The portal is complete and 21 yd. of lining. No. 6 tunnel, at 28 m. 62 ch. (length, 583 yd.), is now being manned. The north approach is in hand. Formation on the section is manned to full capacity and is now 75 per cent, complete. The formation is ready for platelaying to 22 m. All road-alterations, new access roads, and streamdiversions are complete. Fencing is well in hand. The heavy culverting programme is complete, and forty-one have been placed, ranging in size from 10 ft. in diameter to 12 in. pipes. AlO ft. subway bridge has been placed at 19 m. 70 ch. Several district roads have to be metalled in order to transport construction material. In all, 6| m. have been metalled, with considerable benefit to the district. Permanent-way is now laid to 20 m. 34 ch., and ballasting is in hand to 19 m. 63 ch. Heao Section (29 m. 70 ch. to 31 m. 70 ch.). —The Heao Station access road, 2 m. 70 ch. long, has been formed and metalled to connect the railway-construction works with the Stratford-Taumarunui Main Highway, and will be used for transport of all material. This road taps the railway at 30 m., and from there a tramway is being built to serve the heavy formation and two tunnels in the Heao Valley. All work on this section is now being rapidly opened up. Stratford Main Trunk Railway—West End. Raekohua Section (47 m. 40 ch. to 50 m. 60 ch. ; length, 3m. 20 ch.). —This section was not prosecuted very vigorously during the previous period and for the first six months of this year, the main effort being directed towards the prosecution of the tunnels further ahead, these being the factors governing the final completion of the line and the establishment of through traffic between New Plymouth and Auckland. During the last six months, however, the opening-up of the Egmont Colliery Co.'s works and the desirability of providing suitable rail access for their coal traffic has necessitated the expediting of this section and the number of men employed has been increased to enable this to be done. The objective is to open the permanent line as far as 50 m. 40 ch. for coal traffic by September of this year. The formation is well in hand and only about 24 ch. yet remains to complete. The bottom heading of No. 1 tunnel on this section, at 49 m. 6 ch., 7 ch. in length, has been driven right through and breaking down has commenced, while tunnel No. 2, at 49 m. 74 ch., 10 ch. long, has been lined and completed, together with portals. The following bridges have been completed : At 48 m. 15 ch., two 25 ft. and one 30 ft. spans ; at 48 m. 24 ch., one 45 ft. span; at 49 m. 16 ch., one 25 ft., one 30 ft,., two 40 ft., and one 60 ft. spans; at 49 m. 63 ch., two 30 ft. and one 40 ft. spans. The piers of these bridges were completed during the previous period, but the steel girders for the superstructure were assembled, erected, and the permanent sleepers laid during last year. Four concrete culverts with a total length of 293 ft. were constructed, and the permanent fencing erected on the right from 49 m. 62 ch. to 50 m. 3 ch. and on the left from 49 m. 37 ch. to 49 m. 67 ch. A start has been made with platelaying, and rails have been laid from 47 m. 56 ch. to 48 m. 54 ch., the first and second lifts of ballasting being placed from 47 m. 60 ch. to 48 m. 34 ch. A tri - weekly passenger service was maintained between Tangarakau and Tahora, where it connected with the New Zealand Railway service, and during the year 13,000 tons of goods were hauled over the section. The workmen's accommodation at the main camp at Tangarakau was well maintained during the period. At the beginning of 1929 the Egmont Colliery Co., whose property is about 4 m. up the Tangarakau Valley, commenced building operations, and a start was made on the earthworks of their siding.

Heao Section (50 m. 60 oh. to 57 m.; [length, 6 ra. 20 ch.). —During the first half of the period operations on this section were largely confined to the No. 2 and No. 3 tunnels, but later in the period additional men were engaged and the formation between tunnels No. 3 and No. 4 was put in hand to enable a start to be made with No. 4 tunnel, and bottom headings were pushed forward to facilitate transport ahead and enable future operations to be carried on without resorting to the use of long and expensive jigs or roads over the ridges. Good progress was made with the earthwork in the Mangaone and Mangatete Valleys until the wet weather set in towards the end of the year and caused several heavy slips, which held up the cutting-work somewhat. Between 50 m. 60 ch. and 53 m. 46 ch. formation is well on towards completion, and from 53 m. 46 ch. to the start of No. 4 tunnel at 55 m. 17 ch. it should be completed in about another six months. At tunnel No. 2 (52 m. 10-50 ch. to 52 m. 65 ch.) the bottom heading has been completed and the tunnel enlarged and lined to 52 m. 45-60 ch. at the west end and to 52 m. 51-58 ch. from the eastern end, and this leaves approximately 6 ch. yet to enlarge and line. No. 3 tunnel (53 m. 46 ch. to 54 m. 30 ch.) : The bottom heading was advanced to 53 m. 74-76 ch., and the enlarging and lining was completed from 53 m. 52-05 ch. to 53 m. 62-44 ch. in heavy and wet ground. No. 4 tunnel (55 m. 17-50 ch. to 55 m. 68 ch.) : The approaches to this tunnel are in hand, the west end proving very dirty, while the east end promises to be a solid face. An 8 ft. by 6 ft. water-drive at 53 m., 90 ft. long was completed with face-walls and another 12 ft. by 10 ft., at 53 m. 25 ch., 231 ft. in length, was driven through very heavy ground, which made progress slow, and lined. A 6 ft. by 4 ft. water-drive at 54- m. 51 ch., 118 ft. long was driven, but is not yet lined. Two stream-diverts, totalling 10 ch. were completed, but a good deal of extra work was involved due to slips. The Mangaone quarry, which has been providing stone for the concrete lining in No. 3 tunnel, was kept in full operation for the greater part of the period, until the breaking-through of No. 2 tunnel enabled stone to be brought forward from Raekohua. During the period 2,762 cub. vd. were quarried and crushed. Transport on this section is difficult owing to the necessity for pushing the work on the forward tunnels before the earlier ones are holed through. This has necessitated hauling over the ridges which are in process of being tunnelled. In order to haul material to No. 3 tunnel before No. 2 was holed through it was necessary to construct a service road over the saddle and into the Mangaone Valley, and all material was satisfactorily transported by motor-lorries. Similarly tracks have had to be made over the ridges into the Mangatete and Tikapuiti Hill valleys. All power for the works as far as No. 3 tunnel was generated at the central power-house at fangarakau Flat and transmitted by power and air lines to the various localities. This outfit has operated very satisfactorily throughout the period. In January of this year the Mangatete Valley was practically virgin forest. With the increase m the number of men accommodation had to be provided both in this and the Tikapuiti valleys. A large cookhouse was built to serve a hundred men, and fitted with a salamander and hot and cold water. A bathhouse, with hot and cold showers, with a similar capacity was also built. Eighty tents, fitted with floors, chimneys, and galvanized-iron roofs, were erected in the Mangatete Valley, and a temporary cookhouse and twenty tents in the Tikapuiti Valley. Palmerston Nobth Railway Deviation. At the date of my last report approximately one-quarter of the formation work on the deviation, including drainage-work, culverting, and fencing, had been completed. During the past year more locomotives and excavating plant became available, and the excavation of the large goods-yard area, involving the removal of half a million cubic yards of material, was pushed rapidly ahead, the conditions for the operation of steam-shovels being very favourable. The clearing of the reserve was finally completed and a further 1,236 lin. ft. of culverting constructed, this completing the culvert system with the exception of two small culverts. The first of the seven road-overbridges, that at Milson's Line, was completed and opened for traffic on the 10th December. The construction of other overbridges was not started. Five test piles were driven at the Mangaone Stream Bridge site. In order to improve the site for this bridge and to straighten the course of the stream, a diversion channel 19 ch. long was excavated, reauirine the removal of 22,000 cub. yd. of material. Four steam-shovels, seven construction locomotives, and two caterpillar tractors were employed on formation, two shifts being worked during the summer period. The embankments, with the exception of a small corner of the goods-yard and the site for the main passenger-station building have been completed. Approximately three-quarters of the excavation of the goods-yard has'been completed, the balance of the spoil being required for overbridge ramps. During the shortened construction period of nine months and a half 207,000 cub. yd. of earthwork were excavated. The main-line formation was completed-to within 42 ch. of the northern junction with the existing Main Trunk Railway. The average number of men employed on this work for the period was 204. On the 18th April last steps were taken to cease operations as a result of the decision by the Government that the construction of the Palmerston North Railway Deviation should not continue. Arrangements were at once made for the transfer of workmen to other works. Most of the plant and material has been transferred elsewhere, and the balance is being sold by auction.

Wellington - Tawa Flat Railway Deviation. The protection of the embankment along the sea-front has been continued for a distance of 3 ch., just sufficient distance to protect the spoil from the tunnels as it is deposited into the sea. Several big blasts have been fired in the quarry, but there is unfortunately only a small percentage of the rock suitable for the sea-wall, the balance being disposed of for road metal. The railway-bridge across the Hutt Road has been completed. In No. 1 tunnel the heading has now been completed, 14 ch. having been done during the year under the co-operative contract system at the south end and 26 ch. by the contractors from the north end. An adit 13 ch. long was driven to expedite the progress of the heading and the tunnel enlargement. The heading was exceptionally wet, and four shifts per day have been necessary throughout the work. At both ends a small amount of enlargement and concrete lining has been done —8 ch. at the south end and 5 ch. at the north end. The full plant necessary for the more rapid progress of this tunnel is now installed, and good progress is expected under the co-operative contract system. At No. 2 tunnel the approach cutting at the south end was completed during the year. The heading has been driven for a distance of 19 ch. at the south end, and 3J ch. of enlargement have also been completed. At the shaft which was completed during the year, and which is 53 ch. from the north end of the tunnel, the heading has been driven 15 ch. southwards and 17 ch. northwards ; 2 ch. of enlargement have also been done here to act as a depot for receiving trucks from the faces and for plant and materials coming down the shaft. At the northern end of No. 2 tunnel 18 ch. of heading and 2| ch. of enlargement have been completed. The plant for this tunnel also is now ready for operating, and much greater speed should be made in the enlargement and lining. The bridge over the Ngahauranga Gorge Road at 3m. 29 ch. has been completed. Bridges at 6m. 18 ch. and 6m. 38 ch. were also completed. Foundations for the bridge-piers at 7m. 25 ch. have been excavated, and the piers are completed for the bridges at 7 m. 37 ch. and 7 m. 63 ch. The Takapau Road overbridge is in hand. Stream-diversions have been completed at 6 m. 46 ch., 6 m. 57 ch., and 7 m. 8 ch. Two cuttings have been taken out beyond No. 2 tunnel, at 6m. 18 ch. and 7m. 45 ch. Another cutting, at 6 m. 42 ch., has been half completed. A road-deviation at 7 m. 58 ch. has been completed, and another one, at 7 m. 30 ch., has been commenced. Accommodation for the workmen is nearly completed. For married men seventy-four houses were erected and a further thirty are in course of construction. For single men 170 huts were erected, and also two cookhouses and four bathrooms. Two classes of operations are now in progress in the tunnels on this railway which have not been used successfully in tunnels in this country before. These are the loading of excavated rock by means of compressed-air shovels and the placing of concrete in the lining by means of concrete-guns or pneumatic concrete-placers. It is hoped to make comparatively rapid progress by these new processes. Midland Railway. Murchison Section (63 m. 10 ch. to 86 m.; length, 22 m. 70 ch.). —The main activity on this line during the first six months of the period was the completion of the section to the end of the Gowan station-yard at 67 m. 3 ch. The formation was completed early in the year, and platelaying and ballasting was put in hand. Seven culverts were built, varying from 12 in. to 8 ft., and 14 ch. of heavy road-deviation was completed, while a further 23 ch. are in hand. In the latter half of the period the work was very much accelerated, a number of additional men being employed, and formation put in hand up to 72 m. 0 ch. Bushfelling was completed from 67 m. 6 ch. to 67 m. 33 ch., and from 68 m. 69 ch. to 69 m. 0 ch. The largest cutting on the section now in hand is at 67 m. 52 ch., and is being taken out with a steam-shovel and locomotive, the majority of the other cuttings being smaller and more suited to hand gangs. All the buildings at the Gowan station-yard have been completed, and plates have been laid to 67 m., including sidings. Three lifts of ballast have been placed throughout to the end of the Gowan yard at 67 m., and the final boxing-up and finishing-off is in hand. In order to cope with the additional men employed it was necessary to provide accommodation for 250 men at very short notice. Under the circumstances, the men were placed in tents, a cookhouse was erected, and the provision of huts is in hand. The trial-line survey has been completed to 94 m. 7 ch. on the left bank and 93 m. on the alternative right-bank route, but practically all of this will have to be done over again owing to the alterations in the surface of the ground due to the recent earthquake. The survey of the permanent line is complete to 72 m., and is in hand for a further two miles. Westpokt-Inangahua Railway. Cascade Section (5 m. 70 ch. to Bm. 78 ch. ; length, 3m. 8 ch.). —The only work on this section during the period has been the general maintenance and the repainting of all steel structures. Hawk's Cray Section (8 m. 78 ch. to 18 m. 0 ch. ; length, 9 m. 2 ch.). —During the period the bush was felled and cleared from 13 m. to 17 m. 4 ch. From the start of the section to the 10 m. the formation had been practically completed some years ago, and this has now been cleaned up in anticipation of platelaying. From 10 m. to ll m. the formation has been practically completed, with the exception of two cuttings, which are well forward. Between 11 m. and 14 m. formation is well in hand, the main obstacles being the large fillings at 11 m. 40 ch. and 12 m. 20 ch., and the tunnels at 13 m. 26 ch. and 13 m. 41 ch.

. , Tn the case of the filling at 11 m. 40 ch. the material forming this has to be transported some considerable distance from cuttings farther back, and the work has been somewhat hampered by a shortage of light locomotives suitable for the work. This shortage has now been overcome by the provision of a special type of light petrol-locomotive designed by the Department and manufactured locally. Irestles have been erected at both fillings, and it is anticipated that good progress will be made. The portion from 14 m. to 15 m. has only recently been manned. Very complete investigation has been made regarding the foundations for the bridge at 9 m. Och., Cascade Creek and for bridges at 11 m. 34 ch. and 11 m. 78 ch. ' At 11 m. 39 ch. to 11 m. 45 ch. seven out of twenty spans in a temporary bridge were completed, and the excavations for six culverts and stream-diverts have been taken out." The permanent track has been laid from 9 m. 2 ch. to 9 m. 75 cli., and rails are in hand for the next 2 m. of track. Orikaka Section (18 m. to 25 m. 39 ch.). —Survey work has been in hand in this section, but a great deal of it will have to be done again owing to the earth-movement which has taken place, due to the recent disastrous earthquake. A very active policy has been maintained in connection with the accommodation of workmen. niioT camps were started namely, Hawk's Crag, Tunnel Camp, Blackwater, and Berlin's. In all, 112 huts, forty-two cottages, three medical huts, and two bathhouses were erected, while twentyfour huts were shifted from Ohika farther up the gorge. A class-room was added to the school at Liroroa providing accommodation for another thirty pupils. An up-to-date Y.M.C.A. building, with hall, billiard-room, reading-room, canteen, &c., has been provided, and regular entertainments are provided by the Y.M.C.A. During the latter part of the period the number of men and equip i.ent on the works has been considerably increased. The construction of this railway offers several unique features, in that the centre-line is located on the opposite side of the Buller River from the main highway. This side, although the most suitable for the railway location, is too steep and precipitous to allow for the railway-formation and at the same time to provide room for camps or service roads ; consequently all accommodation for the workmen has had to be built on the road side of the river, and even here room for buildings is very scant. The workmen have accordingly to be transported across the river night and morning, and this is done by e provision of ferry-boats working on overhead cables, each operated by a boatman and spaced about every quarter of a mile along the river. South Island Main Trunk Railway. A start has been made with the formation at the northern end of the line from Wharanui southwards. The portion of line from 56 m. sch. to 60 m. 22 ch., with the exception of a gap between 59 m. 25 ch. and 59 m. 67 ch., which had been constructed about thirteen years ago, has been cleaned up to full width, and marram-grass planted on the batters and adjacent sand-drifts where required. Formation ahead is in hand to 60 m. 45 ch. Two married men's huts and twenty single men's huts have been erected, the men having been accommodated in tents temporarily. SURVEYS OF NEW LINES UNDER CONSTRUCTION, NEW RAILWAYS, ETC. Gisborne-YVairoa Survey. Two parties have been engaged for practically the whole year on the completion of the survey of the coastal route for the Wairoa-Gisborne Railway, between Waikokopu and Gisborne. The permanent pegging is almost completed. In the earlier part of the year the trial-line survey of the inland route via Hangaroa, Y alley was completed, and comparative estimates of coastal and inland routes prepared. South Island Main Trunk Survey. The trial-line survey on the north end has been completed, and plans prepared from 62 m. to 66 m. and from 84 m. 30 ch. to 85 m. 50 ch. Permanent-line survey has been completed and plans prepared from 59 m. 28 ch. to 61 m. 50 ch. and from 81 m. to 84 m. On the southern end a start has just been made, and about 3 m. of trial survey have been run from Parnassus northward. North Auckland Railway. A survey of the suggested deviation via the flats fronting Waitemata Harbour, between Avondale and Kumeu, has been made. CONSTRUCTION AND MAINTENANCE OF ROADS AND BRIDGES. Huehue-Waimatenui (Bay of Islands County) .—Formation on this road was widened from 10 ft. to 14 ft. for a distance of 3 m. 27 ch. Knudsen's Road (Bay of Islands County) .—This road was widened for a distance of 80 ch. from 9 ft. to 14 ft. ; 6 ch. formed 20 ft. wide, 10 ch. formed 16 ft. wide, and 4 ch. formed 14 ft. wide Wharepunga Bridge (Bay of Islands County).—Bridge erected 74ft. long, two 30ft." rolled-steel-joist spans and one 14 ft. hardwood span, with 10 ch. approaches.

Kinkopuni-Parakao (Hobson and Whangarei Counties). —3J m. metalling were completed during the |year. A maintenance gang has been employed continuously over the whole length of 12 m. A tractor and grader have also been employed periodically for the purpose of retopping and reconditioning metal surface. The metalling is now complete to the Parakao junction. Pakotai Road (Hobson County). —35 ch. of heavy formation 13 ft. wide, together with two small bridges, have been completed. Waimamaku-Donnelly's Crossing (Hobson and Hokianga Counties). —9 m. 31 ch. bottom-course and 16 m. 27 ch. top-course metalling have been laid down. Several bridges have been erected and four others are under way. Through traffic has used this road continuously since last October. Metalling operations have been continued under extremely difficult conditions in this wet area. The road service is an excellent one, and it is due primarily to the use of cemented gravel, which is well rolled, and was assisted by the wet conditions and to the extensive draining which has been done in the kauri swamps. Horeke-Taheke (Hokianga County). —This road has been formed 18ft. wide for a distance of 4: m. 30 ch. Five bridges were erected, totalling 270 lin. ft. Iwitaua Road (Hokianga County). —90 ch. road have been widened from 10 ft. to 16 ft. and 48 ch. widened to 14. ft. 59 ch. of road have b.een metalled. Mangamuka - Victoria Valley (Hokianga County). —The Mangamuka River Bridge has been extended by four 40 ft. spans, and corners have been extensively cut back. 2,976 cub. yd. of gravel has been spread on the road. Whakarapa -Te Karaka (Hokianga County). —2 m. 42 ch. have been widened to 16 ft. The Lower Waihou Bridge, 160 ft. long, and Whanganamu Bridge, 80 ft. long, have been erected and approaches completed. 7 ch. sea-wall was also built, and 3m. 30 ch. of road metalled.

Two bridges, totalling 54 lin. ft., have been completed during the year. This work is being pushed through to completion. Two small bridges are still required to enable traffic to cross the creeks when in flood. Waiau to Maruia via Lewis Saddle (Inangahua County). —This road is a continuation of .the Springlands Junction to Hot Springs Road via Glenwye and Culverden to Canterbury District. The work has been commenced at the Hot Springs as a relief work. 40 ch. have been formed and 10 ch. metalled during the period. Dorothy Falls Track (Westland County).—This work is being carried out as a relief work, and will give access, when completed, to Dorothy Falls, Lake Kanieri, via Lake Kanieri Road. 60 ch. were formed and metalled. Main South Road (Waiho to Cook's), (Westland County).—32 ch. of 9 ft. road were widened to 16 ft: and metalled. This section has been improved, and when the Docherty and Omoeroa Rivers are bridged tourist traffic will have ready access as far as the Cook's River. Materials are coming to hand for both these bridges, and construction work will be put in hand shortly. The former bridge will consist of four rolled-steel-joist spans on ironbark piles. Waikukupa River Bridge (Westland County).—The portion of bridge damaged by flood has been restored by the construction of three 42 ft. rolled-steel-joist spans and one 25 ft. ironbark span on pile piers.

Armstrong, Whitworth, and Co.'s sole connection with the works was the concluding of the maintenance period of twelve months in respect to works carried out on No. 1 section of contract, which period expired on the 31st December, 1928. The firm's connection with the works ceased from that date. The whole construction work for the year was carried out by the Department, and was generally run on shifts, with practically no interruptions, and progress has been good. At the beginning of the period the position at the power-house was that the coffer-dam has been successfully sealed, the foundations for the four turbine and generator units poured, and parts of No. 3 turbine transported to site. At the end of the period the power-house structure was sufficiently advanced as to provide cover for No. 3 unit, which was completely erected and put into service, supplying power in the first instance on the 3rd June, 1929. Power-house. —Details of work carried out are as follows : The excavation for the foundations of the switch-gear annexe was finished early in the period. The quantity excavated was 1,851 cub. vd., making a total of 9,918 cub. yd. since the Department commenced operations. Good progress was made with the concreting of the power-house structure, which work was carried out continuously on three shifts. Early in the period the foundations of Nos. 1 and 2 units were poured to such a level as would permit the erection of the turbine-casings. As the casings were erected and aligned the concreting of the foundations was completed, but preference was given to the south end of the structure, so as to provide for putting of No 3. unit in service at the earliest possible date. With this in view, the steel frame of the generator-room was commenced from the same end, and subsequent to its completion the walls and roof were concreted over and around No. 3 unit. Later on in the period the walls and roof were extended over No. 2 unit. Foundations for No. 1 machine are well advanced, the turbine and lower machine floors being poured. Subsequent to the completion of the excavation under the switch-gear annexe and air ventilatingshafts, concreting was commenced there, and has been completed, with the exception of the roof of the upper switch-gear room. The remaining concreting-work to be completed comprises the roof of the switch-gear annexe, the generator-room floor, walls, and roof around No. 1 unit, and the workshop and unloading-bay, together with the low annexe structure. 8,083 cub. yd. of concrete and 114-6 tons of reinforcing-steel were placed in the structure during the period. The erection of the steel frame of the generator-room was commenced early in the period, and has been completed for some months. A contract was let for the laying of the ruberoid roofing, a section over Nos. 3 and 4 units having been completed. Towards the end of the period a start was made with the cleaning-down and painting of that portion of the structure completed. Penstocks. —The erection, riveting, and caulking of the penstocks between the tunnels and the Johnson-Larner valve casings were commenced and completed for the three units, with the exception of the jointer-ring of No. 1. The bituminous painting and enamelling of these sections, together with the completion of that in the tunnels, has been finished for Nos. 2 and 3 units. Turbine and Valves.—The erection of No. 3 turbine and valve, which was commenced early in the period, was completed, and the unit later put into service. Difficulty was experienced with the aligning of the outlet casing of the valve, and before the cover could be got into position concrete had to be cut from around the lower portion of the outlet section and flanges eased by cutting out rivets. No. 3 valve was put into service with hand-control apparatus, pending a thorough trial and test of the automatic equipment fitted. Difficulties are being experienced with the governor of this unit, which is apparently sluggish, the speed of the unit due to suddenly throwing off load being in excess of the makers' guarantees. The casing of No. 2 turbine has been erected, aligned, and grouted in, the runner and guide vanes erected, and the main valve completed except for the control gear. The erection of the governor, which is on site, and turbine'details, comprising the lubricating, compressed-air and oil-pressure system, have yet to be^done. No. 1 turbine casing and outside casing of the valve have been erected, aligned, and grouted. Tail-race. —At the beginning of the period the work of clearing the tail-race of spoil dumped by the late contractors into the river from the power-house excavation and of enlarging and straightening the channel itself was put on three shifts. A sand-bar across the old river-bed, at a point approximately

B—D. 1.

58

one mile below the power-house site, had been formed on the diversion of the Waikato River over the Waiteti Flat. Pumps were installed at this spot and were successful in reducing the water-level in the old river-bed from level 146 ft. to level 1-35 ft. This level was further gradually reduced till November last, when water-level 129 was reached, which permitted excavation in the dry. The greater portion of the excavation was in the first 20 ch. down-stream from the power-house, from which length a total of 63,000 cub. yd. was removed, over 10,000 cub. yd. being handled in one month. Owing to the awkward location in the gorge, all material had to be handled by the use of three cranes, loaded into trucks, and hauled to near-by dumping-grounds. All material in the bed of the river above the 129-0 level was removed; this, together with the widening, should have the effect, neglecting the backing-up of the river below the sand-bar, of providing a maximum tail-water level of 145-0 for full-load conditions of eight turbines. The whole of the tail-race work was completed by the end of April last, and the tail-race was at once brought into use for the drying-out period of No, 3 unit on short circuit. The total tail-race excavation was 70,300 cub. yd., all except 4,000 cub. yd. being done during the period under review. To provide against possible erosion of the floor of the tail-race immediately in front of the draughttubes, a 30-ft.-wide protecting slab consisting of 12 in. of concrete was laid down for the full length of the power-house structure. Coffer-dam. —To provide for the future dewatering of the gorge above the existing portion of the power-house, on account of future extensions to the power-house and tail-race, piers for a coffer-dam were constructed in concrete across the gorge just up-stream of No. 4 draught-tube ; this work was completed just prior to the coming into use of the tail-race at beginning of May. The completion of the dam, which comprises the placing of steel joists and sheeting, has been left over until it is required. 100-ton Crane.—Subsequent to the completion of the erection of the first section of the generatorroom steel frame the 100-ton crane was erected and put into service on the erection of turbines, valves, generators, &c. Outdoor Station.—Miscellaneous work has been carried out and completed at the outdoor station. This includes alterations to the top of the cable-tunnel, further work on the oil- and water-circulating systems, including the installation and connecting-up of the transformer water-supply pumps, the construction of steel towers, and the erection of cables to the water-rheostat, together with other miscellaneous works. Penstock Intakes. —Trimming and grassing of the batter above the intakes, together with the permanent fencing, has been finished. The completion of the concrete slab near the pump-house is at present in hand. Overflow-channel. —The investigation, by the use of boring plant, into the nature of the tuff near the waterfall, which was in hand at the end of last period, was completed, five holes in all being put down. A certain amount of erosion has taken place at the overfall from the overflow-channel at the Waiteti Flat. A survey of locality has been made, and measures for dealing with the situation are under consideration. Erection of Equipment.—The erection of the equipment has been carried out under the control of the construction staff. The work done is detailed in the Chief Electrical Engineer's report. Waikaremoana Power Development. During the year practically all construction work has been completed. Headivorks. —In the intake-race a temporary timber dam was shifted into the by-pass channel. Should the necessity arise this dam can be removed quickly, and the top 5 ft. of Lake Kaitawa drawn off. The permanent diversion weir was completed in April, 1928, but owing to a serious leakage under the foundation it was necessary to construct a concrete mat between the weir and this wall. Excavation here amounted to 252 cub. yd., and concrete poured to 276 cub. yd. Pumping operations involved a good deal of work, one 10 in., one 8 in., and three 4 in. centrifugal pumps being operated. On completion of the cut-off wall and mat the foundations above and below the weir were grouted under pressure. Tests showed that there is now no appreciable leakage. The spoil-dump below the weir was sluiced away when the stream was turned over the weir. The bed of the stream below the weir was then paved with stone, connected in place, and the banks stone-pitched, 283 sq. yd. being placed. Clay was sluiced into the river-bed up-stream to seal bottom. The temporary spillway in the earth dam was back-filled, 902 cub. yd. being placed. Total filling in the dam amounted to 16,806 cub. yd., and 1,680 sq. yd., of stone pitching was placed in position. In the approach canal the temporary dam was removed when the tunnel-portal was completed, and all stone pitching finished. Excavation totalled 14,498 cub. yd., and stone pitching 1,4-48 sq. yd. The construction of the main-tunnel portal was completed in July, 1928, 177 cub. yd. of concrete being required. Stop-logs were placed temporarily in position. Back-filling behind the portal and over the additional 70 lineal feet of tunnel constructed in cut was completed, 3,328 cub. yd. being placed. The tunnel was filled for testing in November, 1928, and tests revealed that there was a large leakage through the tunnel-lining. Grouting was commenced and the lining was grouted throughout the whole length of the tunnel, and the arch plastered with a cement-gun. Final tests showed that the leakage is now of small proportions. In the spillway-channel to the surge - chamber 530 cub. yd. were excavated and 213 sq. yd. were stone-pitched. Wing walls to the surge-chamber, facing the pipe-line bench, were formed of stone pitching, 82 sq. yd. being placed. All banks of ramps and nigger-head in Lake Kaitawa were removed ; also all floating timber. The pipe-line was completed by the contractors in October, 1928, the total length for two pipes being 7,176 lin. ft. Yenturi meters were installed and the exciter bus-pipe connected. Connection

D.—l

was made bet-ween the No. 3 anchor-block and the Jjarner-Johnson valves. All pedestals were grouted after the filling of the pipe. Between No. 3 anchor-block and the power-house the area was concreted, and. retaining-wall built for drainage purposes : 106 cub. yd. of concrete were poured here. Surface drains were cut across the pipe-line bench to pick up storm-water and prevent scouring. The power-house was completed during the period. The following were the main items'of construction : Completion of the shell of the building ; concreting of Nos. 1 and 2 machine foundations ; Larner-Johnson valves ; workshop and unloading-bay floors ; construction of concrete-block partition walls ; plastering walls ; completing of roofing ; all plumbing ; glazing ; joinery ; drains ; test tank, &c. Under the annexe and at the southern end of the power-house 6,363 cub. yd. of filling was placed, and the tail-race side of the filling has been protected with stone. Total concrete placed, 8,298 cub. yd. ; steel, 160 cub. yd. ; and excavation, 12,403 cub. yd. At the outdoor station all traverser tracks and turntables (three) were completed. All concrete pads for the steelwork were completed, 665 cub. yd. being poured. An oil-filter house in concrete was erected. The following earthenware pipes were laid: 12-in.-diameter cable-ducts, 12 in. by 6 in. diameter cooling water drains, and 9-in.-diameter storm-water drain fed by 6 in. tile and concrete surface drains. Al2 in. tile and concrete drain was laid along the western side of the site for surface drainage. Several slips were cleared away from the western side of the site. The whole site has been trimmed, metalled, and fenced. The cable-tunnel from the power-house to the station has been completed! The length of this tunnel is 557 lin. ft., and concrete required amounted to 570 cub. yd., and excavation to 2,080 cub. yd. The total excavation for the site amounted to 16,165 cub. yd. As conditions now existing are favourable, a culvert and small dam have been constructed across the Kahutangaroa Stream in connection with the lower development. The culvert has a waterway of 150 sq. ft. and a length of 114 ft. Concrete required amounted to 325 cub. yd. A small clay-fill dam of 3,442 cub. yd. was constructed to divert the stream through the culvert. Stone pitchinss amounted to 719 sq. yd. 8 Waitaki River Power Development. This scheme provides for the construction of headworks, power-house, outdoor switch-gear, and transmission-lines for an ultimate development of 100,000 h.p. The work involves a dam 1,800 ft. long, containing 170,000 cub. yd. of concrete, 40,000 cub. yd. of which have to be placed' below water-level of the Waitaki Piver. The power-house will be constructed on the down-stream face of the dam, at the Otago end, and will ultimately house five units, each consisting of a 23,000 h.p. turbine coupled to a 16,666 kv.a. generator. At the beginning of this period a commencement had just been made with the setting-up of the construction camp and of getting plant on to the ground, so that the twelve-months period covered by this report practically includes all work done to the 30th June last. Test borings and similar investigation work were continued till September, 1928, by which time sufficient information was available to enable the exact location of the dam to be finalized. The first essential for construction purposes was the provision of power and light, facilities for transport, and the provision of housing for staff and workmen. Power and light were provided by the construction of an 11,000-volt transmission-line 4 m. long from the terminus at Kurow of the Lake Coleridge system to the works, and the erection of the necessary substation and reticulation. Regarding transport, an investigation showed that requirements would be best served by an extension of railway facilities from the railway terminus at Kurow right on to the site, of the works. Accordingly the necessary four miles of service railway were built, and opened for goods service in December last and for passengers in the following February. The formation was generally light, including some rock-cuttings and two bridges. The railway has already proved to be of great value for transport of heavy plant, and when regular consignments of cement have to be handled will prove a great asset to construction operations. The provision of living-accommodation is a big and expensive feature of the work. At the end of the period under review, 100 married workmen's houses and 145 single men's huts had been built, and building is being continued. Other features now provided include a fully equipped Y.M.C.A.' social hall, cookhouses, bathhouses, &c. Cottages for staff, workshops, offices, "and stores have been built. Regarding the works proper, although the Waitaki River is a powerful stream, subject to seasonal floods, it is considered imperative that not only shall the utmost possible use be made of the low-river stages, but that construction work on the river itself be carried on irrespective of the flood season. The layout of the coffer-dams has been fixed having this need in view, and work is being planned and done to the following programme : Firstly, to construct, under the protection of a central coffer-dam, a section of dam 25 ft. long in mid-stream, carrying concrete to a suitable safe level; secondly, to extend the coffer-dam from the central section of dam on to the Canterbury bank, and build thedam therein to a level above the temporary sluices that must be provided for passing the river while the section of dam on the Otago side is being built; thirdly, to construct the coffer-dam from central section of dam on to the Otago bank of river and continue with that portion of the dam. The remainder of the work will follow in routine order. At the same time the excavation for and concreting of the power-house section of the dam is to be pushed ahead to make room for power-house construction and erection of machinery. The river has been bridged with a strong steel trestle located on the line of the up-stream end of the coffer-dam. This trestle is 540 ft. long and carries two rail-tracks, and is built to withstand the fierce floods that the river is subject to. The steel-sheet piling, 45 ft. long, for the coffer-dam for the central section of dam is all driven, enclosing an area 243 ft. long up and down stream, and 33 ft. wide. The next operation is to dewater and excavate for this section of the concrete dam, the coffer-dam

being secured by heavy strutting as the work proceeds. This central coffer-dam, secured by its enclosed section of the permanent work, will in turn furnish the starting-point for both the Canterbury and Otago coffer-dams. Excavation for the power-house section of the dam has been begun, as also has excavation for the abutment of the dam against the hills on the Canterbury side. A deviation of the main road, 11 m. long, has been completed and put into use. A complete construction plant is already installed or is arranged for. The plant in use includes steam-locomotives, several pile-driving plants, derricks, cranes, air-compressing plants, &c. Plant for concrete-mixing purposes, including bins, is under erection. Three shifts are employed on the river work, and two shifts on some of the other excavation. At the end of June 332 men were employed on the works. RIVER IMPROVEMENT AND PROTECTIVE WORKS. Wairoa River. Tokatoka Stop-banks. —The work of protecting the foreshore of the Wairoa River against tidal and wave erosion, with consequent destruction of the stop-banks, made some small progress this year, 1,373 cub. yd. of rock spalls being placed on the foreshore, including a length of 25 ch. of the Awaroa Stream. 87 ch. of drain were cut between Wallace Road and Creamery Road, and a culvert, 36 ft. long, of 4-ft.-diameter pipes was laid under Creamery Road. Waihou and Ohinemuri Rivers Improvement. During the past year almost the whole work done was on the Lower Waihou River, and that lower end of the scheme is now substantially completed. A summary of the work done there is as follows : Stop-banks constructed by suction dredges, 2m. 60 ch. ; lighter sections of stop-banks constructed by co-operative contract, 2m. 70 ch. ; soiling stop-banks by use of Ruston drag-line excavators, 6 m. 71 ch. ; filling borrow-pits and clearing beams by use of Ruston drag-line excavators, 3 m. 48 ch. Ten culverts, with flood-gates, sizes ranging from 12 in. to 4 ft. diameter, have been built. Roadreconstruction over a length of 80 ch., necessitated by construction of stop-bank, has been done. On various major drains 5 m. 40 ch. of widening, deepening, and making batters has been done by drag-line specially bought for this class of work. 2m. 40 ch. of drain has been enlarged by hand. Willow-clearing and willow-ringbarking have been carried out on a considerable scale. Other miscellaneous jobs have been carried out on various parts of the stop-bank system. As a result of the major flood in July of [last year, the stop-bank was breached at Rotokohu. .The flood indicated that considerable seepage is liable to take place through the sand-core bank on the Upper Waihou. Arrangements are in hand for strengthening the Upper Waihou stop-banks against this risk by building a banquette on to the existing bank. This work will be undertaken during this year by using the Ruston drag-lines. Generally the works have been adequately maintained, and the considerable plant in use has been kept in good condition. Taieri River. With the exception of work required to improve the operation of the contour channel, the construction work on the Taieri River flood-protection scheme is in its final stages. The main stop-bank is completed, except for raising and strengthening its continuation along the left bank of the contour channel, this latter work being in hand. The pumping-station located in the main stop-bank alongside Waipori Lake has been completed. During construction some trouble with foundations was experienced. This was overcome, and extra sheet piling was driven across the line of the building, and concrete rafts laid down in inlet and outlet canals to stop water-seepage under or around the building. The equipment, consisting of three lowlift motor-driven pumps with necessary accessories, capable of handling approximately 80 cub. ft. of water per second each, has been erected, and on test satisfactorily stood up to makers' guarantee. The pumping-station is now in service, and, with the necessary system of feeding drains, constitutes a most valuable portion of the scheme, and will greatly enhance the value of the lower portion of the Taieri Plain. Of the drainage system, 3 m. 61 ch. of the main drain is complete, save for bars or breaks left till the pumping-station and feeding-canal is complete, 80,000 cub. yd. being excavated from this during the year by Ruston drag-line, the remaining length of 60 ch. through Maori Lake being now in hand. Wain's drain, involving 32,000 cub. yd. of excavation, has also been dug with the Ruston drag-line. Wain's drain culvert-box under main stop-bank is in hand. Two road-bridges and four private bridges were built over main drain, bridges being single-span steel-joist structures of about 35 ft. length. The contour-channel road-bridge (length, 200 ft.), a hardwood-timber structure on piled piers, has been completed. The Otokia Railway-bridge has been lengthened 400 ft. to provide additional waterway, the extension being in 40-ft.-span steel-plate girders, through type, on ironbark-pile piers. The removing of the old railway-bank under the bridge-extension is in hand. The contour channel has always been unsatisfactory, in that it is impossible at cost within reason to give it sufficient capacity to carry all waters that flow to it. In the past the overflowing waters have breached the contour-channel banks in innumerable places, thus causing uncontrolled and expensive flooding. A scheme has been got out to provide definite spillways to give relief to the channel and prevent it breaching its banks, the spillway of flood-waters thus being restricted to short periods during the peak of floods. This scheme is now being submitted to the Taieri River Trust for its concurrence before steps are taken to put it in hand.

MARINE. Lighthouses. North Cape Lighthouse. —This light, which consists of an automatic flashing outfit mounted on a concrete base, was erected during the period. The flasher is of the open-flame type, and is contained in a 800 mm. catadioptic lens, the whole being enclosed in a lantern-house and fitted with sun-valve. This light is visible for about seventeen miles in clear weather, and marks the turning-point in the courses of vessels proceeding round the northern portion of the North Island. Manulcau South Head.—This light was converted from a watched oil-burning light to an automatic acetylene outfit. The original lens and lantern-house has been retained, but the range has been reduced to about sixteen miles. Kahu Rocks.—The erection of this light, which is of the Dalen automatic type, was completed during the year. Its main purpose is to mark the position of the group of offshore rocks in this locality. Owing to the great construction difficulty of building on the rocks themselves, the lighthouse has been erected on a prominent point 011 the foreshore and the exact position of the rocks defined by a red sector. The light itself consists of a 300 mm. catadioptic-lens drum fitted with a Dalen incandescent burner with automatic mantle-exchanger and sun-valve. The apparatus is lodged in a lanternhouse with cast-iron murette for the storage of the gas-accumulators, and is built on a concrete base on the top of what is locally known as the Honeycomb Rock, at a height of approximately 80 ft. Cape Egmont.—The existing watched light at this station is one of the older fixed type, being one of the earliest provided by the service. The growth of motor traffic on the adjacent roads and the increasing number of electric lights in the locality make it difficult for shipmasters to quickly and surely pick up the fixed light at this station. It was therefore decided to provide a completely new and up-to-date revolving light giving a triple flash. The apparatus has now been received, and it is anticipated that the installation will shortly be completed. Baring Head Lighthouse. —At present the entrance to Wellington Harbour is marked by two lights—one a second-order oil-burning watched light at an elevation of 322 ft., maintained by the Department, and the other a low-level Wigham light, maintained by the Wellington Harbour Board. For some time past it has been felt that it would be much better if the existing Harbour Board light was strengthened and the Department's light shifted to Baring Head. As a situation for a coastal light Baring Head has a distinct advantage over Pencarrow, and arrangements are in hand to give effect to this policy, provision being made on this year's estimates accordingly. Godley Head.—A new lightkeeper's cottage has been built at this station, and plans are in hand for the conversion of the light itself to automatic operation. The present light is a fixed one, and in these days of universal electric lighting for households and the use of powerful headlights on motorcars it is necessary to provide a light which has a distinct flashing characteristic, so as to avoid any chance of confusing it with other lights in the vicinity. It is mainly for this reason that the conversion is being made. Tory Channel Leading-lights. —An order has been placed for the necessary apparatus to convert these lights, which are at present oil-burning, to automatic acetylene operation. Tory Channel Light on West Head.—Specifications have been prepared and an order placed for the supply of a 300 mm. lens with open-flame burner, sun-valves, &c. for erection on the West Head at the entrance of Tory Channel. At the present time difficulty is sometimes experienced in picking up the entrance in thick weather, owing to the leading-lights being visible over a small arc only. It is anticipated that the provision of this additional light will be of considerable assistance in picking up the leading-lights and in coastal navigation generally. Jack's Point.—lt is proposed to install a new lens at this station and install an automatic openflame flashing burner with sun-valve, and orders have been placed for the necessary apparatus. Harbours. Westport Harbour.—The past year has been a somewhat critical time for this harbour. 111 the earlier portion of the year the entrance was far from satisfactory, and the two suction dredges, " Eileen Ward " and " Rubi Seddon," have been kept steadily at work, and for the latter portion of the period the position materially improved. In view of the necessity for thoroughly investigating the underlying causes for the shoaling of the bar, a Resident Harbour Engineer was appointed and has been very fully employed in such investigations. The information obtained indicates that the main cause of the shoaling on the bar is due to the gradual accretion which has been taking place adjacent to the breakwaters. To cope with this effectually it will be necessary to extend the breakwater another 250 ft., when it is anticipated better results will be obtained with less dredging. During the period 690,230 cub. yd. have been dredged from the bar by the " Eileen Ward " and the " Rubi Seddon." The bucket dredge " Maui " was employed for the whole year in the berthage area, and removed 184,597 cub. yd. of material. The depths at the Crane Wharf berthages were maintained to approximately 25 ft. at L.W.0.5.T., and a large quantity of material was dredged from the shoaling opposite the old Staiths Wharf and the Merchandise Wharf. A great deal of siltation takes place in these areas owing to the large amount of material brought down by freshes, but a reasonable depth has been maintained throughout the year. The Priestinan grab has been employed removing snags in the upper river, and also in the Western Lagoon, where it is hoped to increase the tidal compactment. The protection work at Organ's Island was carried to completion during the year. The whole of the western side of the island, 55 ch. in length, has been faced with rock, and a retaining-wall 8| ch. in length constructed on the down-stream end of the rock facing. A total of 27,665 tons of rock was used in this

D.—l

work, of which 21,765 tons were placed for the twelve months. The willow-plantations at Hannah's erosion fenced offhand additional willows planted as required. The Cape Foulwind quarry has been in operation for the greater part of the year, a total of 26,765 tons having been quarried and transported to the protection works at Organ's Island, the western breakwater, Railway Department, &c. During the year the plant and buildings have been well maintained. The " Eileen Ward " and the " Maui " were sent to Wellington for annual overhaul, and the stream-tug " Mana " and the launch " Erlin " were slipped and painted. Karamea Harbour.—During the past year the preliminary work in connection with the reconstruction of the breakwater has been practically completed and a start made to place stone along the line of the training-wall. The laying of the tramway from the quarry to the outer end of the retaining-wall was completed. This included the ballasting of the track for a distance of Im. 50 ch., the erection of 280 ft. of trestle from the end of the tram-line to the beginning of the retaining-wall, cutting down and recapping the old training-wall, and laying throughout with stringers and rails a total distance of 15 ch. The plant, consisting of petrol-locomotive, portable engine, and compressor, with 5-ton crane, came to hand early in the year, and a locomotive-shed and two extra workers' cottages were erected. The further opening-up at the quarry has been carried out, the work involved being increased by slips from above the high rock-face. It was found necessary to pass round a blunt spur of comparatively soft rock before tapping the outcrop of harder material farther up the Oparara River, and quarrying operations to the end of the year were confined thereto. The recent disastrous earthquake caused very considerable damage to the existing training-wall. Full details as to the additional work required are not yet available, but it is anticipated that there will be considerable additional work on the staging and a probable increase in the amount of stone required. The existing wall has practically collapsed in places, and the work will have to be modified accordingly. Waikokopu Harbour. —The existing works at Waikokopu have been adequately maintained. The hulk " Talune," which was sunk as an experiment to prove the value of a short breakwater, has now broken up entirely, and a contract has been let for the construction of a rock breakwater 5 ch. long. A 2|-mile tramway has been constructed up the Tahaenui Valley, off the Waikokopu Railway, for the purpose of obtaining limestone for the breakwater. Twenty ton trucks have been built for carrying the stone, and are now in operation. The contractor has erected a staging at the breakwater and has commenced the depositing of stone. The installation of a crane, air-compressor, and other plant has been completed at the quarry, and work should now proceed expeditiously. The wiring of the Harbour Board's shed and wharf for electric light for future use with standard voltage has been carried out, and is now in use in conjunction with a small lighting plant. Karaka Point Wharf. —During the year all the timber and materials were landed on the site, and a contract let for erection. The work is now practically complete. Raupo Ferry Slip Extension. —This work was completed early in the year, and this has enabled it to be ready to work in conjunction with the Tikinui ferry slip across the river. Rawene Launch-landing and Motor-landing.—A contract for the construction of the pontoon landing and steps, together with ramp landing for cars, was let early in the year. The bulk of the work is now done and should be completed very shortly. Tinopai Wharf. —A contract has been let for the erection of this wharf. Totara Wharf .—A contract was let for the erection of this wharf in New Zealand timbers, and was completed, together with approaches, early in the year. Whangaroa Wharf. —This reinforced-concrete wharf has been completed during the period, with the necessary shed and cold store. The approaches were faced with rock. Opunake Harbour.—Funds were provided for the Government for the removal of rocks in the fairway and in the vicinity of the wharf, and this work has been carried out, with the result that there is now a depth of 9 ft. 6 in. L.W.S.T., and shipping is beginning to use the port. Half-moon Bay Wharf, Stewart Island.—During the year an extension of 51 ft. long by 31 ft. wide was completed. The approach to the wharf was also widened and strengthened by fitting additional bracing. Miranda Wharf. —This structure, consisting of a wharf and jetty of a total length of 105 ft. 6 in., a galvanized-iron shed, and three retaining-walls, was completed during the period. Matakana Wharf. —This wharf, which is of reinforced concrete, 1,440 sq. ft. in area, and carrying a shed with a floor area of 720 sq. ft., was erected during the year. Whangamata Wharf. —All the timber has been delivered for this wharf, and arrangements are in hand for its erection. Howick Wharf. —Extensive repairs were carried out at this wharf. General.

DEFENCE WOBKS. New Zealand Aie Fobce Base, Auckland. Construction of the combined aeroplane and seaplane base at Hobsonville has been put in hand, and both the landing-field and the land hangar are now in use. Extensive clearing and levelling for landing-runways, involving 17,000 cub. yd. of excavation, have been completed, and the whole field sown down in permanent grass. 90 ch. of fencing and 56 ch. of metalled access roads have been completed. The apron for seaplane-hangars has been formed by combined excavation and reclamation on the shore-line, and 17,000 cub. yd. was excavated and placed in reclamation, protected by heavy stone retaining-wall. A hardwood-timber jetty, 286 ft. long, has been built, and the construction of a slipway in reinforced concrete for landing seaplanes is in hand. All concrete piles have been driven, and six piers are complete. The deck-slabs are being precast and are 50 per cent, complete. Besidence for Officer Commanding, central office, control hut, boat-shed, and three cottages for airmen are complete. Three additional cottages are 90 per cent, finished. One land hangar, floor-space 5,671 sq. ft., with workshop and offices attached, is complete. Transport-shed, with, accommodation for crashtender, ambulance, tractor, huck starter, and car, is also complete. This latter building and the hangar are in reinforced concrete. Water-supply has been installed, and connections made to the various buildings ; the water is obtained from well bores, is filtered, and pumped into a 12,500-gallon watertower 30 ft. high. A sewerage and storm-water system is being installed and is 80 per cent, complete. A transformer and switch-hut has been built, and underground cables laid for reticulation of power and light to the various buildings. Telephone cables have been laid underground, and a central exchange with connections to the various buildings installed. A commencement has been made on the seaplanehangars. Waikato Camp, Ngabuawahia. Work has steadily progressed on the Waikato Camp during the year, and the establishment is now practically completed. Magazines Nos. 8 and 10, a S.A.A. store, Ordnance workshops, butcher's shop and cool store, permanent shower-baths, Ordnance workshop, fencing, motor-garages at quarters, and permanent coal-enclosure have been completed. The magazine laboratory and the camp hospital are under construction. The preparation of the battalion areas has been finished, and a considerable amount of draining, tree-planting, and fencing has been attended to. Sixteen acres of the magazine area have been cleared and burnt. Maintenance of all completed works, including roads, has been attended to, and many new fittings put into the Ordnance stores, including tables, cupboards, trucks, and trollies. IBBIGATION—CENTBAL OTAGO. Operation op Completed Schemes. During the past year the several completed schemes have been maintained in good condition, and all lands requiring water have been supplied. Of the schemes in operation, the following nine were operated during the year on a trading basis : Ida Valley, Galloway, Teviot, Bengerburn, Ardgour. Tarras, Earnscleugh, Manuherikia, and Last Chance ; as against four for the preceding year. The financial results of the year's operations were : Bevenue, £13,726 ; working-expenses, £11,089 ; profit on working, £2,637 —the profit representing a decrease of £1,4-73 as compared with last year. The reasons for this decrease are, firstly, the inclusion in the trading accounts of the five additional schemes, in which irrigators are as yet paying only on the lower scale of the graduated rates ; and, secondly, the general reduction in rates following on the adoption of the Irrigation Committee's recommendations.

The number of irrigators and the total area irrigated on all Government schemes for the past year is as follows :—

The totals as above compare with figures for the previous year of 306 irrigators and 32,949 acres under irrigation. New Schemes under Construction. HaivJcdun Scheme.—This scheme is, for all practical purposes, completed, and a full service can be given next season. The work for the year comprised construction of distributory races, of bridge crossings, gates, measuring-boxes, measuring-weir, and similar details. Arrow River Scheme. —All pipes for the gorge pipe-line and the numerous siphons on the distributory races have now been delivered on the site, and the erection of these is making good progress, the work of erection including construction of pile bridges across the Arrow River in the gorge, of concrete saddles and anchorages, &c. Detail finishing-work 011 the races is in hand. It is anticipated that a partial supply early in the irrigation season will be available, and that a full supply to the whole area will be available about the New Year. Ida Valley Scheme. —Owing to the very heavy demands on the Manorburn reservoir for the supply to Ida Valley and Galloway, the quantity of stored water has been very seriously depleted. It has become evident that the construction of the Poolburn dam, which was part of the original scheme, should be undertaken without loss of time. Necessary surveys and plans have been made with a view to the early commencement of construction. As an emergency measure a temporary low-lift pumping installation is being put in alongside the Manuherikia River, capable of pumping 16 heads of water to the Galloway races for supply at the Galloway area. This will reduce the demand on the Manorburn dam. Surveys and Investigations. Investigations and reports on several small proposed schemes have been made. River-gaugings and meteorological records have been fully kept up. The several demonstration plots that have been laid down on the border-dyke method have been maintained and kept in operation to demonstrate the results and economy in use of water that are obtained by that method. TRAMWAYS. Auckland.—l 4 ch. of new track was laid and inspected in Halsey Street. No new cars were inspected, but sixteen cars were inspected following accidents. Napier.—One car, converted to one-man operation, has been passed and is now in operation. Wellington.—s6 ch. of new track was inspected during the year, comprising 19 ch. of Chaytor Street duplication, .Karori, and 37 ch. of the Northland extension. Wanganui.—Two one-man cars have been inspected and passed for traffic. Christchurch. —During the year two small sections of new line were constructed, the first being a curve connecting lines in Moorhouse Avenue and Colombo Street, the second an extension of 4ch. of the Quarry Road at McCormick's Bay. The following linos were relaid : (1) Addington line, Lincoln Road, 61 ch. of single and 6 ch. of double track ; (2) on the New Brighton line, 53 ch. of single track ; (3) Colombo Street, between Moorhouse Avenue and Hereford Street, 40 ch. of double track. All of these works were duly inspected and passed. The North Beach line between Burwood and North Beach was reopened for traffic after having been closed, for some considerable time. Invercargill. —During the year four of the regular two-man cars were converted to one-man operation and inspected accordingly. All cars on this system are now under one-man operation.

APPENDIX C. ANNUAL REPORT ON BUILDINGS BY THE GOVERNMENT ARCHITECT. The Government Architect to the Hon. the Minister of Public Works. Sir, — I have the honour to submit the following report on the activities of the Architectural Branch of the Department for the year ended 30th June, 1929 : — During the period plans were prepared for seventy new works, of a total estimated value of £571,525, of which thirty-five contracts, to the amount of £132,755, have been let. 1 n addition, twentyseven contracts, to the amount of £191,327, for buildings designed prior to the 30th June, 1928, have also been let, making the total of works completed or under construction £324,082. The latter total includes £57,839 for secondary-school buildings, and £6,970 for hospitals, &c., designed for Hospital Boards. In addition to the above totals for buildings designed in Head Office, a large amount of minor additions, alterations, and repairs, and general maintenance of public buildings has been carried out by District Engineers, and a considerable quantity of furniture and fittings has been manufactured in the Public Works workshops for various Government Departments. New Zealand materials and manufactures have been used, except where the use of imported material was unavoidable, with generally satisfactory results. Competition for Government contracts has been keen, with prices generally showing a downward tendency, and the standard of workmanship has been satisfactory. The recent disastrous earthquake put building-construction methods to a severe test, and it is gratifying to report that Government buildings generally suffered little serious damage. Where such occurred the buildings were erected before the use of steel in combination with concrete became known as a building method. The serious damage to the post-offices at VVestport and Greymouth is directly traceable to the towers, in combination with bad ground for a satisfactory foundation. In no case has other than minor damage been reported to modern buildings or additions in which reinforcement against earthquakes is provided in accordance with departmental practice, and it may therefore be claimed that reasonable protection is afforded the occupants. The following is a schedule of the works carried out during the year . Viceregal Residences. Auckland District.—General maintenance-work has been carried out, and electric bells and heaters installed. Wellington District. —General maintenance-work has been carried out to the main building and various residences, and glazing, &c., of the glasshouse has been completed. Post-offices.

APPENDIX D. ANNUAL REPORT OF THE CHIEF ELECTRICAL ENGINEER. The Chief Electrical Engineer to the Hon. the Minister of Public Works. Sir, — I beg to report on the position of the development of electric power in the Dominion for the past year as follows : — GOVERNMENT SCHEMES IN OPERATION. LAKE COLERIDGE ELECTRIC-POWER SUPPLY. The year ending 31st March, 1929, represents the fourteenth year of operation of the Lake Coleridge scheme, and the year's working shows very satisfactory results. The attached tables (I, 111, and V) give the analysis of results obtained for the year's operation, connected load details being given in Table IV. Financial Results. The capital outlay at the end of the year was £1,581,262, as against £1,561,081 for the previous year, showing an increase of £20,181, and is analysed in Table 11. The total revenue for the year was £186,963, as compared with £171,127 for the year ending 31st March, 1928, and after payment of all charges, including interest and depreciation, but not sinking fund, a surplus of £50,374 was shown. This amount has been credited to the Sinking Fund Account, bringing that fund to a total of £112,839, to which must be added accrued interest earned of £2,931, bringing the total amount to the credit of the sinking fund to £115,770. The arrears of sinking fund contributions as at the 31st March, 1929, are now reduced to £7,561, and all arrears should be„ wiped out next year. Table I shows particulars of financial results and load records. The total cost per unit generated was 0-303 d., being a decrease of 0-069 d., due to increased output with a decrease in operating-costs. Total operating-costs have decreased by £9,924, due to decreased management and generating costs and decreased Harper diversion maintenance. Particulars of working-costs are shown in Table 111. Connected Load. The total connected load at the end of the year was 157,399 kw., being an increase of approximately 15-4 per cent, on that of the previous year. Details of connected load are given in Table IV. Power-house Load and Operation. The maximum output from the power-house for the year was 24,370kw., representing an increase of 15-9 per cent, over the previous year's maximum. This increase is a normal one, and the addition of the Lyttelton-Christchurch Railway electrification demand has not materially affected this figure. Units output from the power-house totalled 108,011,955, as against 93,853,759 for the previous year, an increase of 15 per cent. The maximum units generated for the year in any one day was 368,500, on 28th March. The annual load-factor was 50-7 per cent., or 0-3 per cent, lower than that of the previous year. There was no overload experienced on the full capacity of the plant (27,000 kw.), and no calls were made on the tramway stand-by plant for this reason or due to any interruption to supply. During the period from 31st March to 30th June, 1929, the maximum demand on the power-house reached 27,540 kw.—viz., on 19th June. Transmission-lines . The Glenroy-Glentunnel section of the north line was converted from 7/-135" aluminium to 19/13 copper at the end of June, 1928, and there remains now only one section of main transmission-line to be converted to copper —viz., twenty-four miles of north line between Hororata and Christchurch. This work was not put in hand during the year owing to the high cost of copper, but will be carried out when the copper-market becomes more favourable. Progress in live-line insulator-testing and line-work has been maintained, and interruption to service reduced by changing insulators and poles without shut-down. No extensive routine insulatortesting, however, was carried out during the year, as the available staff was employed on extra work in new-line construction and the overhaul of wiring systems.

66 kv. Substations. The following table shows the installed capacity of each substation, together with the maximum demand and units output

Addington Substation. After a period of twelve months' shut-down, during which new field coils were obtained and fitted, the 6,000 kv.a. condenser was placed again in regular service on the 31st July, 1928, and has since operated satisfactorily. On the 18th September, 1928, a second new bank of 12,000 kv.a. transformers arrived, and the old north bank of transformers (5,000 kv.a.) was dismantled in November, the station operating with a transformer capacity of 17,000 kv.a. pending the completion of the installation of the new 12,000 kv.a. bank. This bank is now completed and ready for service, and the bank being replaced is being converted to outdoor self-cooling type for use at Oamaru Substation. The capacity of the transformers at Addington Substation has now been brought to 29,000 kv.a. Further trouble, due to low insulation readings on the bushings of the ironclad switch-gear, was experienced, and more replacement of bushings has been found necessary. Interruptions to Supply. (a) Christchurch Supply. The total number of interruptions to Christchurch supply exceeding 1 minute was nine, and the total time of same was 1 hour 47£ minutes. The longest period, of 1 hour 15 minutes, occurred on the 22nd February. The trouble was due to a period of dry dusty conditions, followed by heavy early-morning fog, causing a flash-over and damage to several insulators on all lines between Hororata and Christchurch. The interruption occurred at 5.30 a.m., and fortunately caused a minimum of inconvenience to consumers. Steps were immediately taken to have all insulators wiped down on the sections of lines affected, and no trouble has since been experienced. Of the remaining eight interruptions, totalling 32J minutes, three were due to failures of insulators on transmission-lines, two to trees blowing over on the lines, one to failure of 0.C.8. bushing, and two to troubles at the powerhouse. (b) Ashburton Substation. The total number of interruptions to supply at Ashburton, apart from those prearranged, was sixteen, and the time of same 1 hour 42J minutes. Of this number, five of the interruptions affecting Christchurch also affected Ashburton, the total time of same being 24J minutes. Of the remaining twelve, four were due to broken wires on the transmission-line between Hororata and Ashburton, one to insulator-failure on transmission-line between power-house and Hororata, two to trouble at Hororata Substation, three to trouble at Ashburton Substation, and one unknown. (c) Timaru Substation. The total number of interruptions to this supply, apart from those prearranged, was twenty, and the time of same 2 hours 15£ minutes. Of this number, thirteen of the interruptions affecting Ashburton also affected Timaru, of a total time of 1 hour 5£ minutes. Of the remaining seven interruptions, six were due to transmission-line troubles (causes not ascertained), and one due to failure of insulator on air-break switch at Timaru Substation. (d) Oamaru Substation. The total number of interruptions to this supply, apart from those prearranged, was twenty-one, totalling 1 hour 33f minutes. Of this number, twenty of the interruptions affecting Timaru also affected Oamaru. The remaining interruptions, therefore, were caused by faults on the transmissionline between Timaru and Oamaru. Design Work. The design and layout of No. 1 unit (8,830 kv.a.) involved considerable work, owing to spacerestrictions in 'the existing building, which had been originally built to accommodate machines of smaller capacity, and for architectural reasons the extension was built to the same width as the original. Special provision had to be made to accommodate the turbine relief valve which is of the jet dispersing type, a feature which is not incorporated in the other turbines in this station. To provide for the heavy hydraulic thrusts developed, particular care was called for in designing anchorages for the valve and hood, and adequate steel reinforcement had to be provided to withstand the stresses imposed.

For the Lyttelton-Christchurch electrification the design office prepared layout drawings covering the electrical equipment for the guidance of the electrical staff, and drawings in connection with the new arrangement of the 11,000-volt switch-gear in Woolston Substation were also prepared. General. In connection with the electrification of the Lyttelton-Christchurch line, a contract was let in August, 1927, for supply of two 1,350 kw. rotary converters, together with all switch-gear for conversion of 11,000 volts A.C. to 1,500 volts D.C. A contract for the substation building at Woolston to house this equipment was let in April, 1928. Considerable delay was experienced in delivery of equipment and in completion of the building. The machinery commenced to arrive about the middle of October, 1928, and despite difficulties due to unfinished state of building and non-arrival of certain apparatus the full equipment was installed, dried out, and tested at the end of January, 1929. Actual supply for electrification purposes was available at the beginning of February, and the formal opening of the line took place on the 14th February, 1929. During the year the construction work for the Lyttelton-Christchurch Railway electrification supply at Woolston Substation was completed, a special duplicate circuit 11 kv. line being constructed for this purpose. This line was completed and tested on the 12th January, 1929. An annexe to the above substation has been Used to accommodate 11 kv. switch-gear for the supply of local consumers by the Department, and the low-tension supply to all wholesale consumers supplied by the Department has been converted to 11,000 volts, and on the removal of the old substation these consumers will be supplied through the new 11 kv. switch-gear. During the year two areas of supply have been sold to local supply authorities : (1) The Department's consumers north of the Waimakariri River, to the North Canterbury Electric-power Board ; (2) the Department's wholesale consumers in the Hornby-Jslington area, to the Springs-Ellesmere Power Board. The North Canterbury Power Board took over all the Department's reticulation north of the Waimakariri River on Ist July, 1928. In February, 1929, several main-line interruptions were caused by a continued period of fogs coupled with dust where the lines parallel roads, and it was necessary to employ gangs of men to wipe down insulators between Addington and Aylesbury on the south and middle lines, and between Addington and Bealey on the north line. The construction of the North Canterbury duplicate circuit 33 kv. line was completed and put into service at 11 kv. on the 15th March, 1929. This supply will be changed to 33 kv. on the installation of the new outdoor transformer-banks at Addington. The new outlet weir at the lake was completed in April, 1929, thus bringing the normal level of the lake to 1,672 ft. Installation op No. 1 Generating-unit. During July, 1928, the work of installing the third 7,500 kw. (8,830 kv.a.) generating-unit was commenced. The weir-basin has been completed and the tail-race widened. At the 31st March last 1,340 ft. of pipe-line had been fitted and riveted up. To date (30th June, 1929) the pipe-line has been completed with the exception of the closing-piece at the power-house, and the generating-set bed-plate has been grouted in and part of the turbine and generator lined up in position. Rainfall. The rainfall at the power-house for the year was 36-28 in., and the number of rainy days was 132— a record. MANGAHAO ELECTRIC-POWER SYSTEM. Financial Results. The capital outlay at the close of the year was £2,416,713, as against £2,373,921 for the previous year, an increase of £42,792, which is analysed in Table X. The net revenue for the year was £114,148 ss. 6d., as against £44,111 15s. 2d. for the previous year, an increase of £70,036 10s. 4d., or 158-8 per cent. ; and the gross revenue for the year £186,712 125., as against £155,856 10s. Id., an increase of £30,856 Is. lid., or 19-8 per cent. The increase in net revenue is largely due to a reduction in the amount of power purchased from outside sources. During the year power purchased cost £72,563 6s. 6d., as against £111,744 14s. lid. for the previous year, or a decrease of 54 per cent. Included in power purchased during the year is £15,038 9s. 4d. from Waikaremoana hydro-electric power scheme, which is a credit to that scheme and a debit to Mangahao. Working-expenses were £34,344, as analysed in Table XI. The gross financial results of the system are analysed in Table XIII. Operation and Maintenance. Headwords and Power-house. Storage was available in the upper Mangahao dam from the beginning of the year, heavy rainfall in April filling the dam and causing the automatic gates to tip. Several minor troubles were thus brought to light, but these have been rectified and the gates have since functioned satisfactorily. For several short periods during the year the storage was insufficient to meet the demands on the station, and it was necessary to call on stand-by plants to give relief. Since generation was commenced by the Waikaremoana Station the number of such calls has been reduced considerably, and it has been possible to maintain ample storage in the Mangahao dams. A water-level indicator has been installed at the upper Mangahao dam, and is operating satisfactorily, as are those at the two other dams and at the surge-chamber. Painting has been carried out on the pipe-lines, and the surge-chamber-gate

85

D.—l

operating equipment has been cleaned and overhauled. The turbines and generators have operated very satisfactorily during the year, practically all trouble being due to broken turbine buckets. In order to cope with the increased demand on the station a new set of nozzles, slightly larger than the originals, has been purchased. These are now to hand, and will be fitted when the Waikaremoana Station is able to take over the bulk of the load on the system, thus releasing the local machines when required. Transmission-lines. —110,000-volt Lines. Mangaore- Khandallah Line. —During the year there have been nine complete interruptions on this line, totalling 22 hours 17 minutes. Of these, five interruptions, totalling 22 hours 2 minutes, were due to trouble caused by salt spray on insulators; two, totalling 9 minutes, were due to unknown causes ; one, of 4 minutes, was traced to a flash-over ; while one, of 2 minutes, was due to a switching error at the power-house. In the light of subsequent experience it is reasonable to assume that the interruptions on this line due to unknown causes were actually -caused by salt spray on the insulators. This line has been thoroughly overhauled, and is now in good order. Mangaore - Bunnythorpe Section —West Line. —This line has been in service through the year, supplying power to the Manawatu-Oroua and Wanganui-Rangitikei Power Boards. Other than prearranged shut-downs, totalling 6 hours 10 minutes, there have been nine interruptions to service, totalling 5 hours 18 minutes, and these were all caused by salt deposits on the insulators on the Bunny-thorpe-Wanganui section of the line. The lengthening of junipers and hanging of weights on the Bunnythorpe-Wanganui section have been completed, and this line is now in good condition. Mangaore - Bunnythorpe Section—East Line.—This line has been in service during the year for the supply of power to Hawke's Bay and Wairarapa, and since the end of January, 1929, for the supply of power from the Waikaremoana Power-station to the Mangahao system. Other than prearranged shut-downs, totalling 2 hours 16 minutes, there have been nine interruptions to service, totalling 2 hours 13 minutes. Two interruptions, totalling 42 minutes, were due to the failure of rotating insulators on the air-break switch at Woodville Switching-station, while another interruption, of 3 minutes, was possibly due to a fault in one of these insulators which later failed completely; one interruption, of 8 minutes, was traced to a flash-over at an air-break switch at Waipukurau Substation which brought the line out at the power-house. Pour, of a total duration of 54- minutes, were due to flash-overs caused by salt deposits on insulators ; and one, of 26 minutes, was due to some cause unknown. The lengthening of jumpers and hanging of weights to the revised schedule have been completed, and this line is now in good condition. The groyne at the Manawatu River crossing has been cleared of debris and a few more willows planted to fill gaps. Bunnythorpe-Wanganui Line. —Service to the Wanganui-Rangitikei Power Board has been given on this line during the year. Interruptions recorded total forty-four, of 127 hours 16 minutes duration. Of these, twenty, totalling 15 minutes, were traced to faults on the Power Board system, which tripped the 0.C.8. at Bunnythorpe ; two, totalling 4 hours 40 minutes, were due to a lightningstroke which set fire to a transmission-line pole ; twelve interruptions, totalling 33 hours 55 minutes, were due to line troubles caused by salt deposits on insulators ; one, of 12 minutes, was occasioned by switching operations, during the transfer of load to the Waikaremoana Power-station, whilst another, of 10 minutes, was due to the failure of supply from that station ; two interruptions, totalling 3 hours 47 minutes, were necessitated by troubles which developed in parts of the equipment at Wanganui Substation; while for the remaining one, of 18 minutes, no cause has been found. During the period that trouble was experienced due to salt deposits on insulators this length of line suffered rather severely. Investigation showed that one make of insulator gave somewhat low value of leakage resistance, and it was therefore decided to remove those of that make from this section of line, substituting insulators of higher leakage resistance. The line has been patrolled regularly throughout the year and trees cut where necessary. Bunnythorpe-Woodville Section. —Other than prearranged shut-downs, totalling 5 hours 42 minutes, there were thirty interruptions to service, totalling 4 hours 36 minutes. Three interruptions, of 1 hour 7 minutes total duration, were due to the failure of rotating insulators on an air-break switch at Woodville Switching-station, while three others, totalling 10 minutes, were probably due to the same insula tors before they failed completely ; five interruptions, totalling 21 minutes, were caused by surges when tests were being carried out on the synchronous condenser at Napier Substation ; one interruption, of 8 minutes, was due to a flash-over on an air-break switch at Waipukurau Substation which brought out the line at the power-house ; one, of 10 minutes, was due to trouble at the Waikaremoana Station ; and two, of 7 minutes total duration, were occasioned by switching operations when changing the load from the Mangahao to the Waikaremoana Station ; one interruption, of 8 minutes, was probably due to a jumper on the Mangamaire-Masterton line being blown into contact with a cross-arm during a gale, and one, of 5 minutes, was due to lightning ; three interruptions, totalling 57 minutes, were caused by salt deposits on insulators ; ten, totalling 1 hour 13 minutes, were due to causes which could not be ascertained. A close watch has been kept on the Bunnythorpe-Ashhurst section of this line for cable-strands broken by vibration, but during the year no trouble of this nature has been encountered. At pole No. 177, near Ashhurst, a parallel-groove clamp was tightened under live-line conditions. The line has been patrolled regularly throughout the year and trees cut and tracks cleared where necessary. Generally this line has given good service, and at the present time is in good condition. Woodville-Mangamaire Section.—Other than prearranged shut-downs, totalling 37 hours 49 minutes, there have been forty-two interruptions to service, totalling 10 hours 16 minutes, on this line during the year. Of the remainder, thirty-one were due to the same causes as on the Bunnythorpe-Woodville

D.—1

86

section, except for the longer time delays necessitated by switching operations at Woodville ; these interruptions totalled 5 hours 9 minutes. One, of 50 minutes, was due to a faulty rotating insulator on an air-break switch at Mangamaire Substation, while another, of 4 minutes duration, was due to a flash-over at a jumper on pole 1269 during a gale, which swung the jumper sufficiently close to the pole to cause arcing. Six interruptions, totalling 3 hours 42 minutes, were occasioned by switching operations when transferring load from the Mangahao Station to Waikaremoana ; one, of 24 minutes, was due to transformer trouble at the Mangamaire Substation, when the conductor through a L.T. bushing broke at the insulator and allowed the cable to come in contact with the transformer-tank ; two interruptions, of 7 minutes total duration, were due to causes which could not be ascertained, although it is suspected that one was due to trouble on the Tararua Power Board's system, which tripped the 0.C.8. at Woodville. The H Pole at the corner of Woodlands and Broomfield Roads has been replaced by a new structure, the one originally erected having decayed and was considered unsafe. Earth-strip has now been removed from all poles on the sections from which the earth-wire had previously been removed, and guy-wires have been tightened where necessary. Preparations are now in hand for " stubbing " weak poles on this section. Mangamaire-Masterton Section. —Other than prearranged shut-downs, totalling 46 hours 33 minutes, there have been forty-five interruptions to service, totalling 11 hours 6 minutes. Of the remainder, forty-two were from the same causes as on the Woodville-Mangamaire section, and accounted for 10 hours 53 minutes, leaving three interruptions, of 13 minutes duration, which were traced to troubles on the Power Board's system. These had opened the 0.C.8. at Mangamaire. Woodville-Dannevir/ce Section. —Other than prearranged shut-downs, totalling 12 hours 27 minutes, interruptions on this line during the year totalled forty-eight, of 7 hours 42 minutes duration. Twentyseven, of a total duration of 5 hours 5 minutes, were due to same causes as on the Bunnythorpe-Wood-ville section; three interruptions, totalling 10 minutes, were traced to.weighted insulators on the Dannevirke-Waipukurau section being blown in towards the pole during a gale and arcing over ; four, totalling 9 minutes, were caused by a cable on the Dannevirke-Waipukurau section working out of its clamp and making intermittent contact with the pole ; six interruptions, totalling 1 hour 31 minutes, were entailed by switching operations when transferring load from Mangahao to Waikaremoana Station ; while one, of 10 minutes duration, was due to the resulting surge when an 0.C.8. at Woodville was closed on to a fault at Mangamaire. The causes of the remaining seven interruptions, totalling 37 minutes, could not be ascertained. Dannevirke-Waipukurau Section. —Other than prearranged shut-downs, totalling 9 hours 56 minutes, there were forty-six interruptions recorded on this section during the year, totalling 18 hours 48 minutes. Forty-one were due to the same causes as on the Woodville-Dannevirke section, and totalled 18 hours 27 minutes. The extra time was taken in patrolling the line and holding this section out of service when a cable came out of its clamp. This fault occurred at night, and could not be located until daybreak. Two interruptions, totalling 6 minutes, were caused by lightning, and one, of 4 minutes, was due to a fault on a Power Board's line, which caused the 0.C.8. at Dannevirke to trip ; two, of 11 minutes total duration, were due to causes which could not be traced. Protection work at the foot of towers on the Tukituki River crossing has been continued, and periodical inspections of all river-crossings have been made. H poles have been tightened up and earth-strips removed from poles of the section from which earth-wire had been removed. A cotterpin was replaced in a tie-down clamp under live-line conditions. W aipukurau-N apier Section. —Other than prearranged shut-downs, totalling 19 hours 38 minutes, there were fifty-five interruptions on this section during the year, of 19 hours 47 minutes total duration. Forty-nine, totalling 19 hours 28 minutes, were due to same causes as on the Dannevirke-Waipukurau section ; two interruptions, totalling 7 minutes, were caused by faults on the Power Board's 11,000-volt lines, while one of 6 minutes was due to lightning ; three, of 6 minutes total duration, were due to unknown causes. River-crossings have been inspecte dregularly, and pole No. 1005 near Raukawa has been straightened and concreted. Transmission-lines. —ll,ooo-volt Lines. Mangaore-Shannon Section.—Other than prearranged shut-downs, totalling 2 hours 26 minutes, four interruptions to service, totalling 17 minutes, were recorded on this section during the year. Of the remainder, one, of 3 minutes, was occasioned by the manual operation of the switches in the powerhouse, to relieve the station of overload, which was lowering the frequency. Leakage relays have recently been installed on these feeders. Khandallah-Hutt Power Board Section.—Forty-nine interruptions to service, lasting 13 hours 26 minutes, were recorded on the Hutt feeders during the year. Of these, twenty-five, totalling 5 hours 48 minutes, were due to troubles on the Power Board's lines ; one, of 5 minutes, was due to the failure of supply on the main transmission-line, due to a flash-over at pole 629, while two, totalling 12 minutes, were due to insulator trouble on the main line ; one interruption, of 4 minutes, was due to the operation of the overload relays on No. 1 feeder when the load was transferred from No. 2 feeder during trouble on the latter ; two interruptions, of 2 minutes total duration, were caused by lightning ; one, of 6 hours 28 minutes, was caused by the Ngahauranga line fouling the Hutt line when the former was damaged during a heavy gale —the Hutt feeder was kept out of service to minimize danger when repairing the Ngahauranga feeder ; one, of 2 minutes, was due to the breaking of a jumper at an airbreak switch on No. 2 feeder, while one, of 20 minutes, was caused by a fire at pole 78 ; one, of 5 minutes duration, was occasioned by switching operations at Khandallah Substation. The remaining thirteen interruptions, totalling 15 minutes, were due to causes which could not be ascertained.

Khandallah-Petone Railway Section.—Other than prearranged shut-downs, totalling 104 hours, there were thirteen interruptions to supply, totalling 12 hours d minutes, recorded during the year. One, of 7 hours 53 minutes, was due to the breakdown of a transformer supplying solenoids on remotecontrolled air-break switches in the railway-yard ; one, of 5 minutes, was due to the failure of supply from power-house owing to a flash-over at pole 629 on the main transmission-line, while two others, totalling 12 minutes, were due to insulator troubles on the main line ; three interruptions, totalling 2 hours 37 minutes, were occasioned by fires on poles on the Hutt line. Six interruptions, totalling 1 hour 17 minutes, occurred on a Sunday when the Railway Department's feeder was being used by the Power Board to supply Hutt Valley. Of these, two, lasting 2 minutes, were due to overload, and one, of 1 minute, was to enable the overload-relay settings to be altered. Two interruptions, lasting 1 hour 12 minutes, were due to troubles on the Power Board's lines, and one of 1 minute was due to some unknown cause. Khandallah-W ellington Meat Export Co. Section.—Other than prearranged shut-downs, totalling 28 hours 3 minutes, there have been six interruptions, totalling 12 hours 35 minutes, on this section during the year. One, of 4 hours 37 minutes, was due to water getting into current-transformers at the Ngahauranga Works, and one, of 7 hours 38 minutes, was caused by a break in the line where chafing had taken place at a binder ; one interruption, of 5 minutes, was caused by a flash-over at pole 629 on the power-house-Khandallah transmission-line, and two, lasting 12 minutes, were due to insulator trouble on the main line. The remaining one, of 3 minutes, was due to switching operations at Khandallah Substation. Transmission-lines.—General. The third series of tests on insulators by the buzz-stick method is now nearing completion, only a portion of the Bunnythorpe-Wanganui section requiring retests on insulators reported a.s defective after the initial test. All units reported as defective have been replaced with tested units and forwarded to Khandallah for testing on the oscillator. This latter test is a gauge of the efficiency of the buzz-stick method, and generally the results of the latter are confirmed. Generally, all lines have operated satisfactorily throughout the year. A large percentage of interruptions recorded on the main transmission-line was due to salt deposits, which gave trouble in February and March last, after a long spell of dry weather. Such conditions will have to be guarded against in the future, and it is clear that all insulators must be cleaned periodically. It seems not improbable that some means will be devised whereby this can be done under live-line conditions, thus reducing considerably the number of interruptions required for work on the lines. With the commencement of operation of the Waikaremoana Station the existing protective equipments at substations between the two generating-stations became inadequate to cope with the altered conditions of power being fed from either end of the system, and a complete new system of protective gear has been ordered. This will be coming to hand and will be installed during the current year. In addition, a high-tension synchronizing equipment is being installed at the Mangahao Station to enable the two power-houses to be paralleled on the 110 kv. side of the main transformers. At present paralleling can only be done on the 11 kv. bus-bars, necessitating a short interruption on the Bunnythorpe east line every time the two stations are paralleled. Sap-testing has been continued on the poles of the whole system, and experiments have been carried out with a view to arriving at the best means of strengthening poles which show an undue proportion of sap. Several poles have been replaced on the Woodville-Masterton section, and at the present time others are being strengthened by " stubbing." A check has been kept on lightning-storms occurring in the area traversed by Mangahao lines, seventeen being recorded during the year. Only one storm did appreciable damage to the system, pole d 32 on the Bunnythorpe-Wanganui line being damaged by fire after the line had been struck by lightning. Two strings of insulators were shattered, and the lightning-arrester fuses at Wanganui Substation were blown. At the same time one of the Wanganui Power Board's feeders was struck and a potential transformer on their switch-gear at the substation damaged. Another lightningdischarge struck the Bunnythorpe-Wanganui telephone-line, burning through the wire. Substations. The apparatus at all substations has operated satisfactorily throughout the year. Synchronous condensers have been erected at Khandallah, Dannevirke, and Mangamaire Substations, and have been run as required for voltage regulation. _ Two rotating insulators on air-break switches at Woodville Switching-station and one at Mangamaire Substation failed during the year and were replaced. All the damaged insulators were of the hollow type, with which trouble has been experienced previously. New metering equipments have been installed at Khandallah, Bunnythorpe, Mangamaire, Masterton, Dannevirke, and Waipukurau Substations, and the metering-apparatus at othfir stations has been checked during the year. A new substation is in course of erection at Marton, to provide a second point of supply to the Wanganui-Rangitikei Power Board. At Napier Substation a battery-room has been erected and a 110-volt battery installed for 0.C.8. controls. Similar batteries have been installed at other substations in place of the 30-volt primary batteries originally used for 0.C.8. controls. A fire did considerable damage to the garage at Woodville Switching-station, and destroyed a truck housed therein. The garage has since been reconstructed. A considerable amount of work has been done at all substations in improvement of grounds, and at Khandallah a large amount of testing-work has been carried out for the whole system.

General. The operation of the whole system throughout the year has been satisfactory, many of the difficulties of the earlier years of operation having been overcome. With the growth of load on the system, particularly since the inception of operation of the Waikaremoana Station, the purchase of additional equipment at substations becomes necessary, and at the present time additional oil circuit-breakers are being installed at Napier, Waipukurau, Dannevirke, Woodville, and Bunnythorpe Substations. Again good results have been obtained with the buzz-stick method of testing insulators on live lines, and the third series of tests is now nearing completion. Linesmen have been brought to the power-house for a " refresher " course in this work immediately prior to the commencement of the annual tests on the lines. The results of tests this year confirm those obtained in previous years, two makes of insulator standing out as much better than other makes at present in use. Apart from the testing of insulators, on only two occasions has it been necessary to work on transmission-lines under live-line conditions. At pole 177, near Ashhurst, a parallel-groove clamp was tightened, and on the Dannevirke-Waipukurau section a cotter-pin was replaced in a tie-down clamp while the line was still in service. Trouble is still occasionally experienced with A.C.S.R. cable, broken strands resulting from vibration. Between power - house and Bunnythorpe eight broken strands have been detected, all being in the spans adjacent to the Manawatu River crossing. Repairs have been effected and investigation made as to means of overcoming this trouble. Similar trouble has been experienced in other parts of the world, and various types of damping-devices have been tried, some with marked success. Similar devices will be tried on our lines during the coming year. Tail-race. —Additional groynes have been built in the tail-race, existing groynes extended, and fascining carried out at many places. The tail-race is now in good order, and protective works are standing up well. Design Work. During the year the electrical design office prepared plans and issued drawings for the staff dining-room and for the single men's quarters in connection with Mangaore Village Settlement. With the advent of power from Waikaremoana it became necessary to prepare fresh layout plans and drawings in connection with Napier, Waipukurau, Dannevirke, Woodville, and Bunnythorpe Substations, to provide for the additional steelwork and switch-gear. Construction. Khandallah Substation. —'During the year erection of the 10,000 kv.a. synchronous condenser and its control equipment was completed, and this plant is now operating satisfactorily as required. A current-limiting resistance has been installed in connection with the 250 kv. testing transformer. Earth-leakage and definite time-limit relays have been fitted to the Petone Railway and the Wellington Meat Export Co.'s feeder panels, and put into service. New printometers have been installed and tested, and are now operating satisfactorily. New ironclad switch-gear has been erected for the control of additional feeders to Wellington City and put into service. Bunnythorpe Substation. —The 110 kv. oil circuit-breaker used as a tie-switch has been re-erected on a steel framework, which permits switch-tanks to be lowered for inspection of contacts when required. New 0.C.8.s have been purchased for this station, and have recently come to hand. Their erection will be put in hand during the coming year. Meantime the necessary concrete foundations have been put down. Wanganui Substation. —A well has been sunk in the substation grounds for a permanent watersupply for the station and cottages. New leakage-relays have been installed on the main 11 kv. switch. Marton Siibstation. —Erection of this station is now proceeding to give a second point of supply to the Wanganui-Rangitikei Power Board. This Board closed down its steam plant as from the 31st March, 1929, and now takes the whole of its supply from the Department. A 1,500 kv.a. transformer has been transferred from Dannevirke and installed at Marton on a concrete foundation. A four-pole structure has been erected and an air-break switch assembled thereon. The necessary 11 kv. switch-gear and metering equipment is on order, but until it comes to hand a temporary supply will be given without metering equipment. Woodville Switching-station. —The garage and workshop, which were destroyed by fire, have been rebuilt, and a shelter-fence has been erected round the cottages. A new 0.C.8. has been purchased for this station, and has recently come to hand. Erection of same will be put in hand at an early date. Mangamaire Substation.- —A 1,500 kv.a. synchronous condenser and the necessary control gear have been erected at this station, and are operating satisfactorily as required. A battery-house has been erected and 110-volt battery installed for supply to condenser and 0.C.8. controls. The solenoid coils on the 0.C.8.s have been changed for 110-volt supply. A battery-charging motor-generator set has been installed in conjunction with the new battery. A spare 1,500 kv.a. transformer has been purchased for this station, and has been dried out ready for service when required. Owing to the high voltage at Mangamaire when Waikaremoana is supplying power to the system, it has been necessary to install an auto-transformer to reduce the L.T. voltage to a normal value. A 2,200-gallon outdoor oil-storage tank has been installed and oil-piping connected thereto.

D.—l

89

Masterton Substation.—An auto-transformer has been installed to reduce the L.T. voltage to norma] when Waikaremoana is supplying power to the system. Dannevirke Substation.—The 1,500 kv.a. synchronous condenser and its control equipment have been erected and put into service. A spare 1,000 kv.a. transformer has been purchased for this station, and after drying out has been put into service. The original 1,500 kv.a. transformer has been removed to Marton Substation, and will be replaced by the one ordered for that station when same comes to hand. The new 0.C.8. has been received on site, and erection will be put in hand at an early date. Waipuhurau Substation.—The 110-volt battery and charging-set for this station have been erected, a battery-house being erected separate from the main substation building. The new 0.C.8. has come to hand, and will be erected as soon as staff for this work is available. Napier Substation.—New switch-gear has been purchased for this station, and is now in course of erection. The 0.C.8. for the Mangahao transmission-line is ready for service, while erection of the two 0.C.8. air-break switches and steelwork for the Waikaremoana lines is nearing completion. For the latter lines two oxide-film lightning-arresters have been erected. Erection of the 4,500 kv.a. synchronous condenser has been completed, and this machine is operating satisfactorily when required. A battery-room has been erected and a 110-volt battery and charging-set installed. A well has been sunk in the station-grounds and a pumping plant installed to give a permanent water-supply. Wanganui-Stratford Transmission-line.—A survey party is at present engaged on the location of this line, and approximately seventeen miles have been pegged. Stratford - New Plymouth Line (50 kv.). —The survey of this line has been completed, and construction will be put in hand as soon as poles come to hand from Australia. Delivery of these poles has been held up owing to the timber strike in that country. This line, which will ultimately be an extension of the Wanganui-Stratford line, and part of the Main North Island transmission system, will be leased to and operated by the New Plymouth Borough Council for power-supply from the Tariki Station until such time as the Department is able to give supply from the Mangahao-Waikaremoana system. Load. The rainfall during November, December, and January was insufficient to meet the demands on the station, and it became necessary to call on auxiliary plants for relief. At the end of January, 1929, the Waikaremoana Station commenced supplying power to the Mangahao system with one 20,000 kv.a. generator. During the early stages of operation at that station many minor troubles were encountered, which made it inadvisable to dispense with the services of the auxiliary plants immediately. These troubles have now been overcome, and with the approaching completion of erection of the second unit at Waikaremoana it is anticipated that ample power will be available to meet all demands for some time to come. The maximum load on the station for the year was 20,960 kw., and the maximum number of units generated per week 2,505,380. Both these figures occurred early in the year, before the Waikaremoana Station was in operation, and indicate that the Mangahao Station was overloaded both on plant capacity and on units generated. In the latter case the overload was 55 per cent. The maximum load on the combined Mangahao-Waikaremoana system is now in the neighbourhood of 36,000 kw. Since Waikaremoana Station has come into operation Mangahao has fulfilled its duties as a peakload station, Waikaremoana being operated on as near a 100-per-cent. load-factor as possible, and Mangahao supplying the extra power required at times of peak load. The high load-factors obtaining up to the beginning of the year will therefore not be reached again except under emergency conditions. This condition of operation will enable the most use to be made of the available water in the Mangahao dams. The results of operation are given in Table IX, and the connected load in Table XII. The connected load is now 211,303 kw., against 170,068 kw. for the previous year, an increase of 24 per cent. WAIKATO ELECTRIC-POWER SUPPLY. Capital Outlay. The total capital outlay at the end of the year on assets provided under the Horahora scheme, together with assets provided under the Arapuni scheme and operated to supply power from Horahora and auxiliary plants, was £1,128,036. not including stocks of £14,310. This is an increase during the year of £154,863. As is shown in Table XXII herewith, the principal items making up the increase are the Diesel plant at Penrose, and the 50,000-volt transmission-line from Ngongotaha to Opotiki, together with increases in the items " Interest during construction " and " Cost of raising loans," which increases represent the proportion of these costs chargeable against the Arapuni assets in operation. The increases in these items have been incurred over a period of some years, and are now for the first time included in the assets on which interest has to be charged against operating revenue. Financial Results of Operation and Future Prospects. The year ended with a loss, after allowing for all working-costs, interest, and depreciation, of £15,291, as compared with a profit last year of £6,176. Annual revenue increased from £125,312 to £135,511 ; working-costs increased from £46,568 to £76,231 ; gross profit decreased from £78,744 to £59,280; capital charges increased from £72,568 to £74,571. No payment to sinking fund is being made this year.

The increase of £29,663 in working-costs is accounted for principally by the increase of £27,531 in the items " Operation and maintenance of auxiliary plants " (Diesel plant and Grand Junction plant) and " Power purchased in bulk." The purchase of power from the Auckland Power Board, on account of the fire at Horahora, cost the Department about £4,750, and, while the total units generated by all plants increased by about 4,900,000, the condition of the river at Horahora caused a reduction in units generated there of about 9,400,000. The deficiency in supply from Horahora, as well as the increase in the total supply, had to be made up by increased output from the auxiliary plants, at much greater operating-cost. While the loss this year has been greater than was anticipated, the delay in completion of Arapuni, combined with the growth of load, made inevitable either some loss or some restriction in the use and extension of electric supply. The purchase of the auxiliary plants was the only means of avoiding such restriction, and it has enabled both the Department and Power Boards to proceed with their extensions to new consumers. There is little doubt that the future advantages resulting from this course will more than compensate for the cost incurred. The table given below is an analysis of the sources and amounts of revenue : — 1926. 1927. 1928. 1929. Revenue from—- £ £ £ £ Large mining companies .. .. 16,476 16,150 16,091 15,767 Four original Power Boards (Cambridge, Central, Te Awamutu, and Thames Valley) .. .. 42,226 50,616 52,487 60,553 Additional Power Boards other than Auckland (Waitomo, Franklin, Waitemata, and Bay of Plenty) .. 504 6,173 18,198 28,303 Auckland Power Board .. .. 10,850 15,139 16,132 10,556 Hamilton Borough .. .. 6,205 6,888 7,452 7,821 Tourist Department, Rotorua .. 276 ,2,202 2,440 2,515 Other wholesale consumers .. 7,432 8,988 9,871 7,133 Miscellaneous 1,861 2,532 2,641 2,863 Total .. .. .. 85,380 108,748 125,312 135,511 This shows considerable increases from both the older and the newer Power Boards, and a drop in revenue from the Auckland Power Board, which Board has been buying any surplus power that has been available. Future Prospects. With the first unit at Arapuni coming into service in June, 1929, and the second in September, 1929, an ample supply of power is assured for the whole District. The first unit will enable the expensive auxiliary plants to be shut down, and, in addition, will supply a considerable part of the Auckland Power Board's load. The second unit will supply the remainder of the Auckland load. The revenue for the coming year will thus be much increased ; but, as against this, almost the whole of the capital charges on expenditure incurred at Arapuni and on the transmission-lines and 110 kv. substations will be chargeable against revenue from the date the first unit starts. Thus it is to be expected that in the first year of partial operation there will be a considerable loss, which is estimated at £29,000, without provision for sinking fund. In the following year it is estimated that revenue will be sufficient to pay all charges, including sinking fund. Design Work. Designs and layout drawings were prepared by the electrical design office in connection with extensions at Penrose Substation; also drawings and specifications for substations at Waiotahi, Matamata, Huntly, Kerepeehi, and Edgecumbe. Consequent upon the advent of power from Arapuni, a complete recast of the layout at Hamilton No. 1 Substation was decided on, and complete drawings for a new building, including switch-rooms, battery-room, office accommodation, oil-filtering equipment, and blacksmith's shop were prepared and issued. Specifications and design data were prepared in connection with the special towers required on the Hamilton-Huntly line. Extensions during the Year, and Future Extensions. General, Additional Consumers, and Connected Load. During tie year supply has been given at the following additional points : Consumer —Bay of Plenty Power Board ; point of supply—Edgecumbe ; date—3oth June, 1928. Supply was given on this date at 11,000 volts over the section of 50 kv. line Edgecumbe-Waiotahi, and thence over the Power Board lines to Opotiki. The connected load, not including Auckland, has increased from 64,580 kw. to 77,121 kw. The number of milking-machines supplied has increased from 3,559 to 4,398, electric ranges from 1,287 to 2,025, and electric water-heaters from 4,163 to 5,431. The maximum load last year and this year has been as follows : Horahora —Last year, 12,400 ; this year, 10,300. System —Last year, 15,700; this year, 15,900.

91

D.—l

The " system total " of units generated and purchased increased from 100,075,668 to 104,992,762. The diversity factor, exclusive of power supplied to Auckland and of connected load in Auckland, is 4 - 85, as compared with 4-1 last year. Horaliora. There were no extensions at Horahora during the year. Additional Transmission-lines. Ngongotaha - Edgeoumbe - Waiotahi 50 kv. Line.—This line was completed and placed in service in June, 1928. Hamilton-Huntly 50 kv. Line. —Except for short gaps at the two ends, this line was completed during the year. Special narrow-base towers have been ordered for the Hamilton end, provision being made for these to carry more than one circuit, so as to minimize interference with property. Arrangements are being made to build a new 50 kv. line from Half-way, on the Horahora-Waikino line, to Waihou and thence to Paeroa (total length about twenty-four miles), to improve supply to Waihou, Waikino, and Kerepeehi Substations. Arapuni-Penrose 110 kv. Steel-tower Line. — This line was completed last year, but examination of the foundations this year showed that a number of them in the heavy clay country had water or wet clay in the bottoms of the holes. In a number of cases the holes were dug out and refilled, and in others holes were bored down to the bottom and broken rock rammed around the grillage. Substations. Penrose (110/22 and 22/50 kv.). —General construction work which had been almost at a standstill during the erection of the Diesel plant was resumed. Outside, the 110 kv. steel structure was extended, and was nearing completion at the end of the year. The runways were extended and pads installed for the new 30,000 kv.a. bank of transformers. Cable-ducts were constructed for control cables and all rockwork and concreting completed. All 22 kv. cables were laid and connected up and a start made on running the control cables to the various 0.C.8.5. The main 110/22 kv. and 22/50 kv. transformers were completed and tested out under voltage. The synchronous condenser-transformers were completed and connected up, but have not yet been used. The 110 kv. 0.C.8.s were completed, and the erection of the remaining 0.C.8.s nearly completed. A protective fence was erected round the whole of the outdoor apparatus, with a special fence round the lightning-arresters. Inside the building the switchgear was completed, and was livened up on the 21st February, the Power Board making use of the gear subsequently. The synchronous condenser (10,000 kv.a.) was erected, but has not yet been dried out. A control board was erected for the control of the 110 kv. outdoor equipment. Practically the whole of the equipment has since been tested out and put into service. Bombay (110/50 kv. and 50/11 kv.). —Work on the permanent equipment was continued throughout the year. The outdoor steelwork was completed in April, and all apparatus, insulators, and bus-bars erected and connected up. Four 1667 kv.a. 110/50 kv. transformers were transported by road from Auckland, dried out, and assembled in position. Four 500 kv.a. 50/11 kv. transformers were also installed, and have been carrying the Franklin Power Board load since the 16th December. Five 110 kv. and two 50 kv. 0.C.8.s were erected, lined up, dried out, and filled with oil ready for service. The whole of the permanent 50 kv. gear, including the oxide-film arresters on the Waikino line, has been in service since the 16th December. Inside the building five 11 kv. cubicles have been erected complete with isolators and metering for the supply of the Franklin Power Board. A control board with mimic bus diagram for the control of all the outdoor gear is complete, and batteries for operating trip circuits and the motor-operated 0.C.8.s are installed. A 10-ton electric crane was erected in the workshop. The old temporary substation has been partly dismantled, but the 50 kv. air-break switches are being retained until the 110 kv. wood-pole line is required for use at 110 kv. The three 250 kv.a. transformers from the temporary substation are being moved to Te Awamutu. Hamilton No. 2 (110 kv.). —The extra steelwork for the incoming 0.C.8.s arrived in May and was erected. The four 110 kv. 0.C.8.s arrived in July, and have been erected and dried out. A thorough overhaul of all the apparatus was made, and the substation left ready for service. A protective fence round the structure has still to be completed. Hamilton No. 1 (50/11 kv.). —The new workshop was completed, and has been of great use. It consists of a covered gantry portion extending over the railway-siding, with a pit for handling transformers. The old crane from Horahora was shortened and erected in the gantry. The building was further extended by a wing similar in size to the original workshop, and has provided much-needed room for storing heavy cases and transformers, and also provides accommodation for the transmissionline repair equipment. A new concrete test-room building has been completed, taken over from the contractors, and equipped. Waikino (50/11 kv.). —Construction work at Waikino continued with the arrival of the seven new 1,000 kv.a. 50/11 kv. transformers. These were dried out and installed, the first bank being put into service on the 24th June, and the second on the sth August. The old arresters on the Bombay line were dismantled and a new oxide-film arrester erected in their place. Improvements were made in the control-room lighting and in keeping dust out of the condenser-room. The old transformers were railed to Hamilton No. 1 to be overhauled and one bank converted for outdoor use at Gisborne. Waihou (50/11 kv.).—Four new 750 kv.a. transformers were installed in place of seven 250 kv.a. transformers. The work was commenced at the end of May ; and completed on the 12th June. The new bank is connected delta-star and on the 11 kv. side will parallel with Waikino and Kerepeehi over the Thames Valley 11 kv. lines. The old transformers which were connected delta-delta were

D.—l

92

overhauled and transferred to Edgeoumbe and Waiotahi Substations. Preparations are in hand for the extension of the building at Waihou to include a workshop and crane. A new steel structure is on order, and the substation will ultimately be remodelled on the lines of Kerepeehi and Matamata Substations. Kerepeehi (50/11 kv.). —The erection of the permanent substation equipment was commenced in April, but work was delayed owing to bad deliveries of materials. The transformers (four 750 kv.a.) were transported by rail to Thames, and by punt and launch across the Gulf and up the Piako River to Kerepeehi on the 3rd October. As supply was already being given to the Power Board through the temporary substation, the whole of the new gear was completed before changing over on the 17th December. The temporary substation was dismantled and final cleaning-up completed in January. Grand Junction (11 kv.). —Two new 625 kv.a. 400/11,000-volt transformers were installed to complete two three-phase banks. These, together with two new 11 kv. 0.C.8.5, enable both generators to supply their full-rated kilovolt-amperes into the system. The older turbine was fitted with a new rotor, and the station was made ready to take full load during July. Improvements were made to the station-lighting and various electrical overhaul work was done, the construction gang finally leaving in the middle of August. Ngongotaha (50/11 kv.). —The outdoor 50 kv. wood-pole structure was altered and extended to provide an air-break switch and terminal structure for the extension of the 50 kv. transmission-line to Edgecumbe and Waiotahi. Edgecumbe (50/11 kv.). — A temporary wood-pole substation structure was commenced on the 11th May with transformer and outgoing line, 50 kv. A.8.5., 750 kv.a. transformer-bank on temporary foundations, and oxide-film lightning-arrester. This was put into service on the 29th June, and supplied the local load as well as some Waiotahi load, which was fed at 11,000 volts over the 50 kv. line. To improve voltage conditions a temporary building was put up and an induction voltage-regulator installed to boost the voltage over the 50 kv. line. This was put into service in October. The construction of the permanent substation started in September, and the indoor switch-gear was put into service on the 12th December. The outdoor 50 kv. switchgear was not completed until early in June, when the transformers were moved to their permanent position and the substation finally put into operation all on permanent equipment. A graded resistance lightning-arrester from Waikino was installed, and the oxide-film arrester moved to its permanent position at Waiotahi. The transformers at this substation are from Waihou, and are connected delta-delta with a neutral earthing reactor. Waiotahi (50/11 kv.). —Construction work was started in November. The substation is similar to Edgecumbe, but the steel structure is simpler, and has only one air-break switch mounted on it. The transformers which had been in service at Waihou were thoroughly overhauled at Hamilton No. 1, and were railed to Auckland and shipped to Opotiki, from whence they were transported nine miles by road to the substation. The substation was finally completed and put into service at 50 kv. on the 9th May, 1929. Matamata (50/11 kv.). —This substation is required by the Thames Valley Power Board to improve voltage conditions in the Matamata area, where the load had grown too heavy to be efficiently handled from Horahora and Waihou at 11,000 volts. The old 50 kv. steel-tower line has been diverted on two new galvanized-steel angle towers, fitted with wooden top cross-arms with double-pin insulators and connected through the top of a steel structure. Construction work started in October, and was practically complete by the end of May, 1929. The substation will not be put into service until the new transformers are installed at Horahora to replace those damaged in the fire in September last. Huntly (50/11 kv.). —This substation is being provided to give a second point of supply to the Central Power Board, whose lines, at present fed at 11,000 volts from Hamilton No. 1 Substation, are too long to serve the northern areas adequately. A start on construction was made in March, and the substation is expected to be complete by the end of July, 1929. Henderson (50/11 kv.). —The 1,000 kv.a. three-phase transformer that was in service at Kerepeehi was overhauled and transported to Henderson, where it will be installed as soon as a new air-break switch which is now on order arrives and can be erected. Operation and Maintenance. Headworks and Power-station, Horahora. Inspection after emptying the race on the 20th May showed practically no more sand had accumulated in it in two months. The amount of sand and debris in the river caused a fair amount of trouble during the year, but it interfered very little with power-supply. Fifteen new runners (out of twenty-four total) and fourteen new guide-wheel castings (out of twenty-four) require replacement, and new ones have been ordered. The roller-train of the non-automatic gate in the weir had several rollers broken on it, probably as a result of its being blocked up with rubbish, and the gate could be operated only with a lot of difficulty for most of the year. Screen-scraping has been necessary continuously throughout the year, as many as three men per shift being required at times. Two failures of condenser-bushings on the Waikino line oil circuit-breaker in Eebruaiy and the breakdown of the local service transformer in March were the only failures of electrical apparatus during the year. A small motor-driven pump was installed near the Pokaiwhenua Stream to enable water-supply for the transformers to be taken from that source when necessary.

Fire at Horahora. On Saturday, the Ist September, 1928, at 7.55 p.m., fire broke out in the workshop and old oil-boiling-plant building. The exact cause of the fire is not known. When first noticed it was confined to the woodwork enclosing an induction-regulator which had been drying out, but had been cut off about noon. The usual inspections of the transformer-house and apparatus had been made, and it is difficult to see how any smouldering action could have been caused in the first place, or could have continued unnoticed for eight hours. The chemical fire-extinguishers were brought into use almost at once, and almost succeeded in getting the fire under, but they gave out in probably less than ten minutes, and the fire spread to some oil that was stored in drums near by, and very soon involved most of that portion of the building. The wooden floor of this building had been replaced with concrete some time before as a safety measure, but the wooden lining of the walls had not been removed. The fire travelled along this wood lining to the wood lining of the roof of the new transformer-bay, and thence to the roof of the main transformer and switch-gear building. The Hamilton Fire Brigade were communicated with, and arrived at about 10.30 p.m., and soon got the fire under control, though it took them several hours playing water on the transformer-tanks to put it out completely. This work was done at considerable risk to members of the Brigade. The damage done was as follows : — To Buildings.—Workshop and oil store : completely destroyed. New 50 kv. transformer bay : Roof completely destroyed. Main building : Roof destroyed on two and a half bays out of four. To Apparatus. —Transformers : Two main transformers (single-phase 5/50 kv.) out of ten total were destroyed ; the others all sustained slight damage to bushings, joints, &c. The new 50 kv. bank of three single-phase transformers without conservators, owing to the air-space above the oil, was practically undamaged. The three 5/11 kv. three-phase transformers in service were practically undamaged. 50 kv. switch-gear : Practically undamaged. 5 kv. switch-gear : The 0.C.8.s in the new 5/50 kv. transformer-bay were little damaged. Those in the original building, where they were exposed to fire from oil from the transformers and reactances, were destroyed. Those in the 11 kv. bay were badly damaged, but capable of repair. All overhead wiring and practically all control wiring in the building was completely destroyed. The damage done amounted approximately to £12,500. The following statement covers the work of giving emergency supply and restoring the main supply : Ist September —8.10 p.m. : All power-supply from Horahora cut off, leaving McLaren's Falls supplying about 2,000 kw. to Waikino Substation. 9 p.m. : Diesel plant supplying Henderson, Takapuna, Bombay, and Hamilton (partial supply). 10.40 p.m. : Auckland Power Board supply came on, and supply was given to Te Awamutu and Hangatiki. 11.28 p.m. : Grand Junction plant on. 11.45 p.m. : The Penrose and Waikino supplies were paralleled, and partial supply was given at all points except Arapuni, Ngongotaha, and the Bay of Plenty Substations. 2nd September. —On Sunday morning a connection was made, avoiding the damaged part of Horahora, to give supply over the Horahora - Arapuni - Ngongotaha - Bay of Plenty line. Thereafter, except for occasional interruptions due to overload in the emergency conditions, consumers were not subjected to any great inconvenience, except for low voltage at the more remote points. 6.45 a.m. : Load supplied was 7,600 kw. 3rd September —6 a.m. : Load supplied was 8,500 kw. 6.35 p.m. : Temporary connections at Horahora enabled it to take over the Cambridge load of 500 kw. 4th September —3.4 p.m. : Horahora supplied an additional 1,000 kw. to Thames Valley - Matamata area. 5.30 p.m. : Total load supplied was 11,370 kw., and apart from the fact that the Waihi Company were cut off, and the Auckland Power Board were supplying 5,000 instead of taking 2,000 kw., supply conditions were almost normal. 9th September —3.44 p.m. : No. 3 transformer-bank put into service, increased load on Horahora by 4,000 kw. 30th September—l.B p.m. : No. -1 transformer-bank, which had been reconditioned and dried out, was placed in service. This has enabled Horahora to carry up to 10,000 kw. total load, the maximum that hydraulic conditions have allowed since. New transformers have been ordered to replace the two destroyed by the fire, but they have not yet arrived. The work of getting the station into service again in stages, and at the same time giving supply from such portions of it as could be used, would have been difficult under any conditions, and was made more so by the very bad weather in September. The Arapuni office took charge of the new building-work, and carried it out very expeditiously under these adverse conditions, combined with the risk of proximity to live wires and bus-bars. Some of the best of our men from other districts were sent to assist, and an offer from the Auckland Power Board to send six of their men was accepted, and under the Station Superintendent and First Operator, Horahora, and the Assistant Distribution Engineer, Hamilton, the work of restoration was carried out practically without a hitch. Transmission-lines. —50 kv. With the exception of the Horahora-Waikino line and two cases of breakdown due to lightning on the Horahora-Arapuni-Ngongotaha-Edgecumbe-Waiotahi line, there have been few line troubles during the year.

The alteration of the Horahora-Waikino line—mounting the top insulator on a short wooden extension of the tower, and the two side insulators on wooden cross-arms instead of steel—has been tried out on a number of towers, and promises to be effective iti preventing trouble caused by birds. As soon as practicable the whole of the line from Horahora to Half-way will be changed in this manner. From Half-way a new section of line will be constructed to Waihou and on to join the Bombay-Waikino line at Paeroa. Live-line testing has been carried out on all lines throughout the year, and a considerable number of defective insulators have been discovered. Six poles which had been weakened by decay were replaced on the Mystery Creek -Te Awamutu section. On the 29th June pole 256 on the wood-pole line near Huntly West was blown over at about 45° without interruption to service, and had to be straightened up. At the same time steel tower No. 254, alongside this pole, was blown over and had to be rebuilt, about one-quarter new members being required for this purpose. A fair amount of tree-cutting has been done during the year, principally on the Mystery Creek - Te Awamutu, Arapuni-Ngongotaha, and Horahora-Waiorongomai sections of line. Fences and gates were erected to prevent danger to stock on bridges on Waiorongomai-Waikino section. On the Te Awamutu - Hangatiki section a pole was found with the top burnt, but with no insulators damaged, the cause of this being presumably a flash-over due to lightning. Substations. Penrose. —The temporary 50/6-6 kv. substation remained in service throughout the year. After the fire at Horahora, cables of greater capacity were put in to enable supply back up to 5,600 kw. to be given by the Auckland Power Board. The necessary connections were made to enable the Diesel plant to supply. Bombay. —The temporary gear supplying the Franklin Power Board remained in service until the 16th December, when the permanent equipment was put into service. Hamilton No. I.—An additional bank of transformers, 1,500 kv.a. was installed, making the total substation capacity 3,000 kv.a. A flash-over on two pin-insulators on the 11,000-volt structure occurred in bad weather in April. Waikino. —The existing two banks of 3,615 kv.a. each of water-cooled transformers were replaced with two banks of 3,000 kv.a. each, self-cooled, and delta-star connected instead of star-star. A new lighting installation was put in. A rat caused a short circuit in the condenser switch-gear. New metering equipment was installed on Thames Valley supply. One of the 50 kv. wall entrance bushings broke down during the year. Two hydrants for fire protection were put up. Waihou. —The existing two banks of 750 kv.a. each were replaced with one of 2,250 kv.a., deltastar connected instead of delta-delta. Arapuni. —Nothing to report. Mamaku. —The 150 kv.a. transformer broke down on the 29th October, the failure being between H.T. and L.T. windings on one phase. It was replaced with a spare transformer from Hamilton after two and a half days' interruption. Ngongotaha. —Nothing to report. Edgecumbe (Rangitaiki).—A temporary substation was erected, and supply given to the Bay of Plenty Power Board by it on the 30th June, 1928, and the change-over to the permanent substation gear was made in stages. On the 2nd February a failure in a trifurcating-box caused earth-leakage relays to operate incorrectly, and made service intermittent at intervals for two days until the fault was repaired. Supply was given to the whole Bay of Plenty area from this substation. The Department's line from Edgecumbe to Waiotahi was used as an 11,000-volt feeder, with an induction-regulator to regulate voltage. On the 15th February a lightning-discharge damaged the arrester slightly. Te Awamutu. —Nothing to report. Hangatiki. —On the 17th January a current-transformer broke down and blew out the back of the incoming panel, setting fire to the compound and causing a short circuit on the incoming cable. This fused the transformer-leads under the oil. Repairs were effected on two transformers, and, using the spare transformer, service was restored after 18 hours 3 minutes. The third transformer was later repaired. The switchboard being out of service, supply was given through temporary connections to the Board's lines. Henderson. —A rat caused a short circuit on P.T. fuses on the 15th April. The spare transformer which had been in use at Kerepeehi was returned to Henderson. Takapuna. —Nothing to report. Grand Junction Plant and 11,000-volt Substation. This plant has been in regular operation throughout the year, running usually from 6 a.m. to 10 p.m. daily. A considerable amount of work has had to be done to the brickwork, grates, and mechanical stokers, to keep them in order, and the boiler-drums have been treated with zinc-white to arrest pitting action. A new rotor for one of the turbines was installed early in the year, and this turbine was again placed in service. Additional 11 kv. switch-gear and transformers, to bring the total capacity up to 3,750 kv.a. (two banks of three 625 kv.a. each), were installed. One ot the older transformers, which had broken down on the previous December, was repaired, and another, which broke down in much the same way on the 19th January, was repaired and placed in service again on the 15th March.

The lighting and wiring of the plant were overhauled. On the 23rd January broken cross-head bolts on the air-pump of one turbine set resulted in considerable damage to the pump, and the set was out of service for repairs until the Bth March. The Junction plant was not called upon to deliver its maximum capacity until the present winter, and its maximum supply to date was 3,400 kw. in June, 1929. Diesel Plant, Penrose. The erection of the Diesel plant was completed in May, 1928. (See last annual report.) Trouble very soon after operation started, mainly in pitting and corrosion of the exhaust-valves, owing to unsuitability of the atomizers for use with the fuel oil supplied. A large number of trials were run with different adjustments of the engines, but without much improvement, and finally the makers were asked if they could supply new atomizers suitable for the oil available. In the meantime arrangements were made to get a sufficient supply of another oil from the Admiralty fuel-tanks at Devonport, and from October to the end of January this oil was used, with satisfactory results. Tests were made early in February, using the original oil with the new atomizers on No. 3 set, with good results after a number of adjustments had been tried, and arrangements were therefore made to change over completely to this oil, which has been used exclusively from the 21st April, 1929. Operating troubles with the engines have been principally due to carbonization of oil, both the cooling-oil in the piston-heads and the lubricating-oil in the air-compressor. On a number of occasions carbonization of the cooling-oil has resulted in blockage of the supply of oil, and on one occasion deposit of carbon inside the piston-head has reduced the cooling effect, this resulting in burning of patches on the piston-head, followed by slight cracking at the burnt patch. Carbonization of lubricating-oil in the air-compressor results in blockage in the intercooler, requiring the set to be shut down until the blockage is removed. In June, 1928, shortly after starting up, a bolted joint in the piston cooling-oil system of No. 1 set came adrift, causing failure of oil-supply and slight seizing of the piston on the cylinder-liner, scoring the latter so that it had to be replaced. In addition to the foregoing, there have been a number of minor troubles on smaller parts, requiring frequent attention and occasional replacement, but on the whole the plant has worked satisfactorily. It has been in regular operation since September, 1928, two units running nearly all the time on full load on six days a week from 5 a.m. to 10 p.m., and three units running occasionally when required. The maximum load carried to date was 4,240 kw., on the 24th April, 1929. 11,000-volt Lines and Substations. There has been little trouble with these during the year. Eight decayed poles were replaced in August on the Horahora Leamington section. Power purchased and generated by Stand-by Plants. Power purchased during the year amounted to 12,776,370 units, including 10,514,730 units from McLaren's Falls and 1,762,070 units from the Auckland Power Board, the latter being mostly obtained in September, 1928, following the fire at Horahora. In addition to this, the Grand Junction plant supplied 5,046,740 units and the Diesel plant 7,070,912 units, a total of 12,917,652. The total units from all these plants was thus 25,694.022, or approximately one-quarter of the total output, as compared with one-eighth for the previous year. Interruptions. Due to 50 kv. Transmission-lines. —Athough interruptions to supply have been more numerous than usual for the year, this has been due rather to the extraordinary conditions of operation than to actual defects in the lines. No insulator breakdowns have occurred on any of the following line sections: WaiorongomaiWaihou, Waikino-Kerepeehi, Waikino-Aongatete, Horahora-Arapuni, Horahora - Mystery Creek-Te Awamutu - Hangatiki, Mystery Creek - Hamilton, Horahora-Hamilton-Bombay-Penrose (110 kv. construction), Penrose-Henderson-Takapuna. The Horahora-Waiorongomai section was responsible for seven interruptions due to insulator failure, one due to a turkey flying into the line, one to trees falling across it, and one to binders and mechanical clips broken in a storm. The Waiorongomai-Waikino section was responsible for four interruptions due to insulator failure. On the Bombay-Kerepeehi section one insulator failed during the year, punctured by lightning. There were no other faults on this section. On the Arapuni-Ngongotaha section there was one flash-over at the time of a severe lightningstorm, and later on pole 77 was discovered to have the top burnt off, with no insulators damaged, but with the telephone and power wires in contact, this being responsible for an interruption of 12 hours 28 minutes. On the Ngongotaha-Edgecumbe section lightning shattered one insulator at pole 320, burning about 2 ft. of the pole-top, and causing an interruption of 17 hours 38 minutes. In addition to the foregoing, there were nine interruptions due to unknown causes, in most cases more than one line being affected.

Due to the following Causes. —Horahora : Fire in transformer-house, Ist September. Failure of condenser-bushings on Waikino line 0.C.8., 17th and 21st February. Waihou : Blowing of 50 kv. transformer-fuses on 3rd, 4th, and sth February, for no apparent reason, interrupted supply at this substation. Waikino : Breakdown of wall-entrance bushing. Three short-circuits of 11 kv. gear were caused by rats. Kerepeehi: Breakdown of bushing in a transformer 11 kv. trifurcating-box. Bombay: Failure of 50 kv. insulator on an air-break switch. Penrose : Flash-over on an 11 kv. fuse. Damage to a trifurcating-box caused by rain through a broken window. A 6,600-volt bushing on the main transformers failed and was replaced. Henderson : A rat caused a short-circuit on an 11 kv. potential-transformer. Hamilton : Flash-over on 11 kv. insulators on the take-off structure during a storm. Hangatiki: Breakdown of current-transformer in the ironclad switch-gear, and damage to leads in main transformers. Mamaku : Breakdown of 150 kv.a., 50 kv. transformer. Edgecumbe: Flash-over on 50 kv. lightning-arresters. Flash-over between 11 kv.. fuses on earthing-reactor. Failure of bushing on 11 kv. trifurcating-box. No trouble occurred at Takapuna, Te Awamutu, Arapuni, and Ngongotaha Substations. General. The Okere plant has been run regularly throughout the year from 6 a.m. to 10 p.m. on six days per week, by arrangement with the Tourist Department. While generally successful, the operation of four plants —Horahora, McLaren's, Grand Junction, and the Diesel plant —in parallel over fairly long lengths of line with each other and with King's Wharf has proved fairly difficult. The 50 kv. system consists of over 400 miles of line, and under the present temporary means of supplying it all from Horahora it has not been practicable to install the gear necessary to cut out a defective section without interruption to the rest of the system. It is probable, too, that on such an extensive system, supplied by comparatively small stations, a fault that is of little importance in itself may cause disturbance in voltage sufficient to cause trouble on some part of the system. Some of the interruptions during the year may be due to that reason. Further, with all plants fully loaded, an interruption which cut off one of them would generally lead to an interruption on all of them, though not in all cases, and the time required to restore service has been increased by the necessity for telephoning instructions re synchronizing, &c., before load could be put on. The bulk of this work has fallen on the operating staff at Horahora, who are entitled to credit for the way in which they have carried it out, as are also the operating staff at Penrose, Waikino, the Grand Junction plant, and Hamilton. Operation of Arapuni (June and July, 1929). —No. 3 unit at Arapuni was first started on 4th May, 1929. Drying-out on short circuit was completed on 31st May, and after relay tests and preliminary governor tests it was run in parallel with King's Wharf for short periods on the 2nd and 3rd June, and regularly from the 4th June —at first from about 3 p.m. to 9 a.m., and then continuously, carrying occasionally up to full load. On the 7th July Arapuni took over the following load—Penrose Area and southern area of Auckland Power Board, Takapuna Substation, Henderson Substation, Bombay Substation, Hamilton Substation, Kerepeehi Substation —and gave supply to it continuously. The Arapuni maximum load was then little over 15,000 kw., with daily output about 250,000 units. Horahora, with the occasional aid of McLaren's and the Junction plant, then supplied the rest of the Waikato system —total load, about 9,500 kw. — and the two plants were not in parallel with each other or with King's Wharf. I regret to have to record the death on the 4th May of Mr. J. W. Swaney, Power-station Superintendent in charge of Arapuni and Horahora. Mr. Swaney had been in charge of Horahora since 1925, and it is due mainly to his energy and ability that the power-station has been satisfactorily maintained during this difficult period. His place at Arapuni has been filled by Mr. W. H. G. Watson, First Operator at Lake Coleridge. Arapuni. Construction. In connection with the civil construction work during the year see Engineer-in-Chief's report. Design Work. Consequent upon the Department taking over from Messrs. Armstrong, Whitworth, and Co., the preparation of new designs for the power-house foundations to take up the ground-stresses as found was undertaken 'by the electrical design office, and detail constructional drawings issued for same. Numerous structural drawings were also prepared for modifications found necessary in connection with other features in the contractor's original designs. Generators. During the year the assembly and erection of No. 3 generator, 17,650 kv.a. (15,000 kw.), was put in hand as soon as the power-house building was sufficiently advanced to provide cover, and by the 4th June, 1929, this machine was completed and placed in service. Good progress is being made with

97

D.—l

No. 2 generator, the rotor and thrust-bearing being assembled and the stator-windings placed in position. It is expected that it will be ready for service by September, 1929. During the year a contract was let for the supply of the fourth generator of 15,000 kw. capacity. Transformers. The assembling and drying-out of the main transformers was completed, and an extra set of service transformers installed in connection with No. 3 generator. The assembly and drying-out of the testing-transformer was also completed during the year. Switch-gear. The 110-000-volt switch-gear was completely checked for connections prior to placing in service. The 11,000-volt isolating-switches and supporting steelwork were erected in the cable-room, and a start made with the steelwork for the 11,000-volt switches. As the building was not sufficiently advanced to permit of the installation of these 11,000-volt oil switches, temporary arrangements were made in connection with the operation of No. 3 generator. The foundations, steelwork, and switches for the 50,000-volt structure for the Horahora tie-line were completed. In the control-room the steel and marble work in connection with the operating-bench was assembled and erected, also the low-tension and watt-hour meter boards completed. Three panels of the control benchboard, the low-tension and the signal board were connected up and placed in service. Motor-generators. The motor-generator set was removed from the temporary shed to its permanent position in the power-house and placed in service. Cables and Wiring. A large amount of this work has been completed, the whole of the system at the outdoor substation, including interlocking, signal, power, and miscellaneous cables being laid and connected up. The main transformer-cables for Nos. 1, 2, and 3 generators have been completed and boxed, and generator, auxiliary, and pilot cables have also been completed for Nos. 2 and 3. Heating and Lighting. The lighting installations at the main dam, outdoor substation, 110,000-volt structure, penstockintakes, and pump-house have been completed, while similar work at the power-house is being completed in the control-room, transformer and cable rooms, and also below No. 3 generator. WAIKAREMOANA ELECTRIC-POWER SUPPLY. During the year practically all civil construction work lias been completed under the direction of the Engineer-in-Chief. Design Work. The design and drawing work to cover the layout of the generating plant and switch-gear was completed. The work included the design of the foundations for two 20,000 kv.a. units and the necessary piping for the forced-lubrication system and water-cooling system in connection with the plant. The design of an artificial loading-tank for testing the main generating units was prepared for tendering purposes, and drawings issued for erection of same in the field. The necessary layout drawings for Gisborne and Wairoa Substations were prepared in the design office and issued for the erecting staff. Power-station. * With the completion of the power-station building, the erection of the 80-ton crane was pushed ahead, so as to facilitate the erection of No. 2 unit. Work on the installation of the 11 kv. switch-gear, control boards, control and main cables, &c., was pushed on at the same time as the erection of No. 2 unit, so as to have all the apparatus ready when it was ready for service. On the 6th December, 1928, water was admitted into No. 2 pipe-line, but, due to water leaking through the bolt-holes at the Larner-Johnson valve, the pipe-line had to be emptied and welding of bolt-heads done to prevent leaking. On the 21st December, 1928, the pipe-line was again filled, and No. 2 unit turned over for the first time at 11.23 a.m., on the above date and run for a short while, and again later in the afternoon, when it was again found necessary to shut down, due to the seating of the Larner-Johnson valve giving trouble. The Larner-Johnson valve was dismantled and all the holding-bolt holes in the seating-ring filled with spelter, redrilled, and. tapped. This unit was again ready for running on the sth January, and after several hours' running, trouble was experienced with the governor. Trouble was experienced off and on with the governor for some days, but by the latter end of January this unit started to carry commercial load, Napier being the first station to receive power from this station. It is also worthy of note that this unit was placed urgently into service without any preliminary testing, and, except for small troubles, the generator has been in constant service since the above date. Work on No. 1 unit was held up pending the arrival of the turbine, which did not arrive until the second week in February. On arrival of the turbine, erection of No. 1 unit w r as pushed rapidly ahead, and by the 26th May, 1929, the generator was ready for drying out.

This unit went into commercial operation on the 12th July, L 929. Some trouble is being experienced in the operation of the pressure-relief valves on both these machines as supplied, and modifications are under consideration. Outdoor Station. The erection of the 110 lev. and 50 kv. gear, reported nearly complete in last year's report, was completed, and final connections made. The 110 kv. 0.C.8.5, together with the isolating-switches, were then connected to their respective control cables and all connections checked. The seven 6,666 kv.a. 110 kv. transformers and 1,500 kv.a. 50 kv. transformers were dried out and placed in position on their foundations, oil and water connections being made to each tank. The station oil-purifying system, together with the fire storage tanks, were connected up, and the oil for the transformers and 0.C.8.s filtered ready for service. The 110 kv. equipment was energized on the 28th January. 1929, and the 50 kv. equipment on the 18th February, when the supply of power was given to Napier and Gisborne Substations respectively. Trouble was experienced with the 110 kv. isolating and air-break switch insulators breaking, and these insulators are now being replaced with insulators of another material. Provision has also been made to flood-light the outdoor structure, so as to facilitate inspection work at night. Several large slips on to the outdoor-station site destroyed portions of the station draining system. This has now been repaired, but it is quite probable that during the rainy season other slips will occur. The temporary power-station was finally taken out of service at the end of May, 1929, though prior to this a start was made to dismantle and re-erect the equipment in the main power-station. No. 5 unit was erected in the main power-station, and put into operation early in June, to supply current to the staff village and power-station. Work on the erection of the L.T. panels and No. 4 unit is being pushed on, and should be completed very shortly. General. Practically all the cable-work is now completed, and, excepting for the water-level indicators and controls for the gates at the surge-chamber, the installation of the power-station equipment is complete. General cleaning-up of the power-station and outdoor station yet remains to be done, also the grassing of the main-pipe-line slope. • Wairoa Loading-shed. All equipment has been removed from this shed, and the building is being left for the storing of equipment for the next development. Waikokopu Wharf Crane. This crane, now that the heavy lifts are over for the present scheme, has been painted, and all exposed parts covered with grease to prevent corrosion by rust. Transmission-lines. 110 kv. Transmission-lines. Tuai-Napier Section. —The work of constructing the main 110 kv. double-circuit line from Tuai to Napier, which was reported nearly complete at the end of June last year, was completed and ready for service in November, 1928, the first circuit being energized on the 28th January, 1929, when load was carried over same for the Napier district. Each circuit can be isolated for testing at three different points, a linesman being stationed at each switch and directly in touch with the power-station by telephone. A considerable amount of work is yet to be done in connection with getting patrol tracks in order, as the recent heavy rains in May last did a considerable amount of damage to same. One cage and two bridges have been erected to facilitate patrol. 50 kv. Transmission-lines. Tuai-Gisborne Section. —Work on this line was pushed ahead well, and by the end of December, 1928, this line was completed except for the erection of the isolating-switch at Tinoroto. When the construction of this line had only just started severe gales were experienced at the Tuai end of the line. As the result of this experience steps were taken to ensure that the line would withstand similar gales in the future. This line was placed into service on the 18th February, 1929, at 9 p.m., and since that date has given no trouble. Near the Gisborne end of the line it may be necessary to divert the line for about half a mile, as during the heavy rains in May last a considerable amount of the country moved. Work on the patrol tracks was also completed ; also the installation of cages across the Ruatikuri and Hangaroa Rivers. This line can be isolated for testing at three different points, a linesman being stationed at each switch and directly in touch with the power-station by telephone. Tuai-Wairoa Line. —When this line was taken over by the Department power was being supplied from the temporary power-station to the Wairoa Power Board at 11,000 volts, and, as this line was to be changed over to 50,000-volt service, this had to be done during the week-ends, so that the Power Board's service would be disturbed as little as possible. By the end of December this line had been converted, and ready for service at 50,000 volts. In case of trouble the line can be isolated at Mitchell's turn-off. This line was placed into operation at 50,000 volts on the Bth April, 1929.

It was necessary to cut away quite a number of trees from the line, and to fix up cages across the Waikaretaheke River. So as to facilitate patrol, three telephone - huts were installed alongside the Tuai-Wairoa Road and the telephones connected on to the main P. and T. line between the powerstation and Wairoa Exchange. Substations. Gisborne Substation (Patutahi).. Work on this station was rapidly pushed ahead, the outdoor steelwork, lightning-arresters, 50 kv. switch-gear erected, and a 1,205 kv.a. bank of transformers from the Hamilton district being placed in position, and connected up ready for service. The 11 kv. switch-gear and regulator, together with the earthing-reactor, were installed and connected up ready for service. The oil-tanks and oilpurifying system were installed in the building provided for same, and connections run out to the 50 kv. transformers and 0.C.8., also into the main station. Two wells were sunk to provide water for the cooling of the transformers, also a water-tank erected to give two hours reserve supply of water in case of trouble with the water-pump. Two linesmen's cottages were erected on the substation-site and are connected directly with the power-station by telephone during the night. The substation building also houses the switchingcubicles of the Poverty Bay Power Board, besides being equipped with a 15-ton crane and workshop for repairing the station-transformer and equipment. This station was placed into service on the 18th February, 1929, and, except for minor troubles, the equipment has functioned satisfactorily. Wairoa Substation. This station consists of one bank of three 500 kv.a. transformers, total capacity 1,500 kv.a., stepping down from 50 kv. to 11 kv., together'with a suitable air-break switch and 50 kv. lightningarresters, the control of this station being from Tuai. The 11 kv. side of the transformers feed directly through the Department's metering equipment to the Wairoa Power Board's substation. Work on the erection of this station was commenced in October, 1928, and by the end of February, 1929, was ready for service, though at this time the Power Board was not ready for the change-over, the station finally going into service on the 6th April, 1929. Interruptions. The following were the interruptions for the period 29th January to 30th June, 1929 : —

WAITAKI DEVELOPMENT.—DESIGN WOKK. Drawings showing the general arrangement of the power-station building have been prepared by the electrical design office, and the detail drawings for this building are being prepared as required. The design and layout of the high-tension outdoor switching equipment have been finalized. Layout drawings for the main generating-machines, together with detail constructional plans, are to be prepared as soon as the necessary certified particulars are received from the manufacturers. Details of the design of the dam and the method of construction have been prepared. Drawings and specifications covering the supply and delivery of two 600 h.p. auxiliary hydro sets have been prepared and tenders invited for same. The arrangement of the village layout has been fixed, and specifications and drawings for the permanent-staff cottages, single men's quarters, and the hostel are now being prepared. Interconnected Transmission-Lines. A large amount of investigation into the electrical and mechanical characteristics of the interconnected Waitaki - Coleridge transmission-lines has been carried out, and arrangements made for suitable equipment to meet the position. To carry out this and similar investigation work a shortcircuit calculating - table has been procured. This apparatus forms a very useful adjunct to the electrical design office, and enables electrical problems of the field to be reproduced in miniature in the office and results obtained which could only be otherwise obtained by long and laborious calculations.

Stability of Transmission-lines. During the past year a technical investigation has been undertaken in connection with the electrical stability of transmission-lines. This trouble, which has made its appearance in older countries, has not yet been experienced in this country, but with the rapid growth of load which is now taking place it has become imperative for the Department to examine its own transmission-lines with a view to forestalling the trouble, and it is hoped that as a result of the investigations now being made it will be able to predict the maximum load over any portion of the lines with fair accuracy and take steps accordingly. Line Surveys. Line-survey methods have been given further attention, and instructions drawn up for the information of district officers, indicating a different basis of procedure in order to obtain the most economical location and layout of transmission-lines without definitely fixing the size of conductors and height of supports. Investigations have been made in connection with longitudinal movement of suspension insulators when excessive spans vary in length, and consideration has also been given to the problems of line-vibration and spacing of conductors in very long spans. BROKEN WIRES AND POLES. During the year there were reported by electric supply authorities 1,547 cases of broken wires and 128 broken poles. Prom incomplete returns the approximate number of miles of each size and material of conductor is scheduled below, together with a summary of the number of breaks reported in the respective sizes of wires in use. The scheduled mileage of conductors erected totals 85,613, and the average number of miles of line per broken conductor reported is 55. Taken on a route-mile basis of 17,759 miles, the number of breaks per route-mile of line erected is very low —viz., 0-087. Falling trees are the principal destructive agent in the case of broken wires, 531 cases, or 34-32 per cent., being due to this cause. There is an increase in the number of broken poles —viz., 128, as against 65 last year —and this is attributed principally to the number of locally-grown bluegum poles erected six or seven years ago and which are now failing due to decay.

ELECTRICAL ACCIDENTS. The following is a list of various electrical accidents reported to the Department for twelve months from the 30th June, 1928, to the 30th June, 1929 : — 3/7/28 Substation attendant received burns to face and arms through opening starting-switch of 2,000 kw. rotary converter in error. (Auckland Power Board.) 18/7/28 Maori boy, aged ten years, electrocuted through climbing transmission-line pole and coming in contact with air-break switch, Ngongotaha-Opotiki 50,000-volt line. (Public Works Department.) 22/7/28 Man received severe burns through wilfully climbing on to substation platform and contacting with live wires. (Thames Yallev Power Board.) 13/8/28 Linesman electrocuted while erecting low-tension line under 6,600-volt line. (Hutt Valley Power Board.) 22/8/28 Assistant linesman received shock and slight burn through slipping while working on pole and coming in contact with 2,000-volt mains and stay wire. (Wellington City Council.) 22/8/28 Assistant linesman electrocuted by contact with live 6,600-volt lines. This man exceeded his instructions and had no right to climb pole. (Poverty Bay Power Board.) 9/9/28 Consumer received severe shock while trying to repair radiator attached to three-pin plug. (Wellington.) 15/9/28 Consumer received shock through broken plug on iron and making accidental contact with oven. (Christchurch.) 23/9/28 A mine electrical engineer received shock and burns while working near 11,000-volt cubicle. (Grey Power Board.) 7/10/28 Boy electrocuted by contact with high-tension telephone-line which had become detached from supporting bracket. (Dunedin City Council.) 8/11/28 Four cattle electrocuted by contact with low-tension line brought down by cattle milling around pole. (Wanganui-Rangitikei Power Board.) 23/11/28 Linesman electrocuted while working on live low-tension lines through not taking proper precautions. (Waitaki Power Board.) 21/12/28 Engineer at hospital electrocuted through using a portable hand-lamp that did not comply with the regulation requirements. (Central Hawke's Bay Power Board.) 27/12/28 Boy received shock and burns from a defective vacuum-cleaner flexible. (Wairarapa Power Board.) 14/1/29 Wireman received shock and slight burns while working near high-tension transformer in cramped space. (Raetihi Borough Council.) 23/1/29 Child received shock and slight burns through climbing on to roof of outhouse and making contact with live wires. (Wanganui Power Board.) 25/1/29 Man received severe shock and cow electrocuted through high-tension line falling and contacting with low-tension line, which in turn livened up wire fence. This further livened up cow-shed through some scrap iron in contact with both. (WanganuiRangitikei Power Board.) 12/4/29 Wireman received shock from consumer's main while working on switchboard. (Napier Borough Council.) 20/6/29 Workman received burns through dropping a spanner on live terminals in undergroundcable box. (Auckland Power Board.) 21/6/29 A carpenter miraculously escaped severe injuries or death when he allowed a piece of metal downpipe to foul 11 kv. line. (Manawatu-Oroua Power Board.) ELECTRIC-POWER BOARDS. Amendments to the original (1918) Act, based on the results of experience, were passed in 1919, 1920, 1921, 1922, and 1923. The legislation was consolidated and amended in the Electric-power Boards Act, 1925, with subsequent amendments in 1927 and 1928. The development of the reticulated areas of Electric-power Boards has continued to make substantial progress during the year. There are now forty-three districts constituted, and thirty-eight actually carrying out the distribution and sale of electrical energy (August, 1929). The total area covered is 66,869 square miles, or 63 per cent, of the total area of the Dominion ; the total population concerned is 922,464, or 63 per cent, of the total population of the Dominion ; and unimproved value of the land included in the electric-power districts and outer areas is £254,032,991, or 74-5 per cent, of the total unimproved value of the Dominion. The attached coloured map shows the location of the various Boards already constituted and the proposed Boards. The areas in which Electric-power Boards have not been set up are, on the whole, comparatively sparsely populated, but there is one locality where it would appear that such a Board could with advantage be formed —viz., the suggested Waimarino Electric-power District, which includes Ohakune, Raetihi, and surrounding district. Since the 31st March, 1929, the Waimea Electric-power District has been constituted, including Richmond, Motueka, Tahunanui, and portion of Waimea County. Nelson City is included in the outer area of this district. The proposed Hurunui Electric-power District is also well on its way towards being constituted. Hobson Electric-power District is extending its area to include Otamatea and Whangarei Counties. So far only one of the four main cities —viz., Auckland —has been included in the inner area of a power district, but of the secondary centres the boroughs of Wanganui, Palmerston North, Invercargill, Timaru, Napier, Hastings, Blenheim, Greymouth, Gisborne, and Oamaru are included. The advantages of Power Board organization are more obvious to rural than to urban ratepayers, and yet the above position indicates that some of the more important centres are realizing that it is to their advantage generally to be associated with the country in undertaking the work of reticulation of electric power on a comprehensive scale.

The Boards already formed are working energetically in carrying out their functions. Twentyfour Boards —viz., Waitemata, Thames Valley, Bay of Plenty, Cambridge, Central, Franklin, Waitomo, Te Awamutu, Hutt Valley, Horowhenua, Manawatu-Oroua, Wanganui-Rangitikei, Central Hawke's Bay, Hawke's Bay, Dannevirke, Tararua, Wairarapa, Malvern, Banks Peninsula, Springs-Ellesmere, Ashburton, North Canterbury, South Canterbury, and Waitaki.—have carried out fairly complete reticulation of their areas, and are distributing power taken in bulk from the plants at Horahora, Mangahao, Waikaremoana, and Lake Coleridge. The Auckland Board has taken over the city electricpower station, and has provided large extensions of both plant and mains. It has also entered into a contract to take the whole of its power, with a minimum of 15,000 kw., from the Government when the Arapuni Station is completed, the first unit of which went into commercial operation in June, 1929. Taranaki is now giving a supply from its own generating-station at Tariki. Wairoa and Poverty Bay are taking power in bulk from the Department's station at Lake Waikaremoana, Wairoa Board supplying the Borough of Wairoa and a large portion of Wairoa County, and Poverty Bay Board supplying Gisborne and surrounding area. Six —viz., Opunake, Taranaki, Southland, Wairere, Marlborough, and Teviot—have local water-power stations in operation, and the Golden Bay Power Board is expected to be operating by September, 1929. The Westland Power Board has delegated its license to Westland Power, Ltd., for a term of years. The Grey Power Board has erected a steam station of its own, and has made arrangements for constructing a hydro station on the Arnold River near Kaimata. The Tauranga, Otago, and Otago Central Boards have arranged to purchase power in bulk from other authorities. The other four —viz., Hobson, South Taranaki, Buller, and Reefton —are making arrangements which have not yet been finalized. Table XXX gives details of the date of constitution, the area, population, and rateable value of each of forty-three power districts already formed, also the amounts of the loans already authorized and the voting of each poll taken. The total amount of the loans authorized by the thirty-eight districts which have taken their polls is £12,309,116. The population of the districts concerned is 884,676, so that the loans authorized amount to £13-9 per head of population, as compared with £12-1 last year. The unimproved valuation of the districts is £247,977,236, the loans authorized amounting to 4-98 per cent, of the unimproved rateable value of the lands pledged as security for the loans. The voting at the polls totalled 55,058 to 9,189 —i.e., a majority of 83-5 per cent. Table XXXI shows the capital expenditure incurred by each Board up to the end of the financial year 1928-29, the revenue and expenditure, and the amount of rates struck and collected. The total capital outlay by the thirty-nine Boards which have started construction is £12,009,891, and a small proportion of this is on works not yet in service. The gross revenue from the sale of electricity by the thirty-eight Boards which had commenced supply was £1,850,453, of which 32-8 per cent, was received by the Auckland Board. The general result is a profit over the whole business of the Power Boards of £100,462 for appropriation to Depreciation and Reserve Funds, &c. During last year six of the Boards struck a general rate, which was collected in three cases, and five of the Boards struck special rates for the security for loans, which were collected in two cases. Several of the Boards have been passing through a critical stage owing to the high cost and high interest rates ruling in 1921, when they started construction work, and to the fact that they have undertaken the construction of many lines without requiring the guarantees from consumers authorized by clause 7 (d) of the 1922 regulations, and since amplified in the 1927 regulations. But costs and rates of interest are now substantially lower, and other Boards have profited by such experiences, and much better results will be attained by the Power Boards generally in future as the result of the experience of these earlier districts. LOCAL ELECTRIC-SUPPLY SYSTEMS. Including the Government plants, there are now (31st March, 1929) thirty-eight public electricpower stations in the Dominion, as compared with forty-one last year. One new hydro station (Westland) came into operation, and one water-power station (Inglewood), and one gas (Opotiki) station were shut down from regular operation when bulk supply became available. Mataura, hitherto scheduled under hydro, is now included with the distributing authorities, as the power is generated by the Southland Frozen Meat Co. The total installed capacity has increased during the year by 17,099 kw., or 11-6 per cent, (from 146,360 kw. to 163,459 kw.), while the sum of the maximum loads has increased by 26,781 kw., or 22-7 per cent, (from 117,445 kw. to 144,226 kw.). The proportion of installed plant is now as follows : — Stations. Kilowatts. Proportion per Cent. Water-power .. .. .. .. ..30 135,007 82-60 Steam - power, excluding hydro stand -by plants at Wellington (10,000), Invercargill (2,450), Waihi (2,500) 3 27,324 16-70 Gas-power .. .. .. .. ..2 112 0-09 Oil-power .. .. .. .. ..3 1,016 0-61 38 163,459 100-00 The number of consumers supplied has increased from 243,795 to 266,306, an increase of 22,511, or 9-2 per cent., for the year. The total pupulation included in the various &reas of electric-power supply is 1,360,976, or 91 per cent, of the total population of the Dominion, so that the ideal of a supply being available to every home in the Dominion is well on the way to realization.

D.—l

103

The maximum demand per head of population in the area supplied is 0-105 kw., 70 per cent, of the allocation of 0-15 kw., or 0-2 h.p. per head of population, which is the basis of the design of the Government schemes. The units sold per head of population supplied were 398, as compared with 320 last year_ The total length of distribution-line is 17,759 route-miles, as compared with 17,063 last year, an increase of 696 miles, or 4-1 per cent. The number of consumers per route-mile is 15, as compared with 14-3 last year, the increase being due to the extra mileage of new lines erected during the year and to the increased generating-capacity made available. The maximum power-demand per route-mile is now 8-15 kw., the sales 30,600 units, and the revenue £211. The units are better than last year (26,800), and there is a slight increase in revenue as against £198 last year, and there is an increase in the maximum demand of 6-9 kw., last year. The revenue per kilowatt of maximum load of all stations was £26, as compared with £28-4 last year. The water-power stations show a revenue of £27 per kilowatt, steam stations of £21-97 per kilowatt, oil stations of £37-01 per kilowatt, and gas stations of £44-28 per kilowatt. These are valuable figures for use in forecasting the revenue from systems of various descriptions. The water-power systems include the greatest proportion of large consumers, and the gas-engine stations the greatest proportion of small consumers. Out of the ninety-six scheduled supply authorities, sixty-nine showed a profit for the year amounting to £673,256, and twenty-seven showed a loss amounting to £159,441. The general result is a net profit for the whole Dominion of £513,81.5 after paying working-costs (£1,814,633) and capital (interest and sinking fund) charges (£1,425,793) at the rate of 5-99 per cent, on the total capital outlay of £23,813,228. This shows a net profit of 2-16 per cent, as compared with 2-13 per cent, last year. The business, on the whole, is thus a thoroughly sound and remunerative one, as well as supplying a public necessity to 91 per cent, of the population of the Dominion. The following table summarizes the results of the year's operations in connection with electric supply throughout the Dominion :—

Results for Electric-power Supply of New Zealand for the Year ended 31st March, 1929.

GROWTH OP LOAD. In the early days of electric supply electricity was used almost exclusively for lighting purposes, but with the advent of electric motors and the application of electricity for heating purposes the power and heating load increased, until at the present time the energy used for lighting is small compared with that used for other purposes. The benefits of electric drive in factories and workshops have to a large extent been taken advantage of, and the use of electricity for commercial heating and domestic heating and cooking is rapidly increasing. The use of electric ranges, water-heaters, and portable domestic appliances, such as radiators, toasters, percolators, vacuum cleaners, and kettles, during the past few years confirms the opinion that the use of electricity for domestic purposes will soon exceed the demand for industrial and commercial uses. An interesting graph has been prepared showing the growth of load from 1919 to 1929, and is published with this report. This graph shows the annual increments in the installed generatingcapacity, aggregate maximum demand on the generating-stations, the number of consumers supplied, number of units generated, and total connected load.

stations does not yet include the units at Arapuni, nor the second unit at Waikaremoana or the ninth unit at Lake Coleridge, and by the 31st March, 1930, the installed-generating-capacity figures will be increased by approximately 75,000 kilowatts.

ELECTRIC SUPPLY IN NEW ZEALAND. STATISTICAL GROWTH OF LOAD. 1919 to 1929.

Returns have again been obtained of electric ranges and water-heaters in use throughout the Dominion, and the figures obtained continue to show satisfactory increases over those of the previous twelve months, and the statistics obtained for the year ending 31st March, 1929, have been scheduled in Table XXXV. Of the ninety-six electric-supply authorities engaged in retail distribution of electrical energy, eighty-six have an aggregate total of 20,254 electric ranges connected to their systems, and the number now installed represents an increase of 284 per cent, for the year. The return shows the percentage of consumers using electric cooking to the total number of consumers being supplied in each area respectively, and an examination of this column shows where the field for electric cooking still remains to be developed. The number of consumers using electric water-heaters has increased from 21,513 to 29,257, an increase of 36 per cent. When electric-supply authorities actively canvass their areas for the above class of load the response is generally favourable, and it is only reasonable to anticipate that in the near future the demand on the available stations will be such as to warrant further extensions to keep up with the requirements. This development of load is particularly noticeable in rural and country areas, where fuel is scarce and where the facilities for more congenial living-conditions are being brought into line with those already existing in the metropolitan areas.

As regards electrically-driven milking-machines, the figures this year show a steady advance over those of previous years—viz., 1925, 3,581 ; 1926, 4,856 ; 1927, 6,738 ; 1928, 8,514 ; 1929, 10,161. The collection of these statistics was inaugurated in 1923, when the total number of electrically-driven machines was only 1,310. The increase in six years is thus 675 per cent., and, as there are still about 8,000 machines which are fuel- or water-driven, the work of conversion is a long way from completion, and the electric-supply authorities have still this additional load of approximately 10,000 h.p. in prospect and ready for canvassing as the reticulation extends farther into the outlying districts. ELECTRICAL SUPPLY AND WIRING REGULATIONS. The Electric Supply and Wiring Regulations, which were gazetted in 1927 with the intention of revising same after two years' trial, are now about to be revised, and all electric-supply authorities have been circularized for an expression of opinion and suggestions for the improvement of same as a result of their experience. The Advisory Committee has continued to meet regularly during the year to consider various questions submitted by the supply authorities in connection with interpretations of certain regulations. During the period from Ist April, 1928, to 30th June, 1929, the Committee was convened sixteen times, and gave answers to 26 questions in connection with the Electrical Supply Regulations and 211 questions in connection with the Electrical Wiring Regulations, in addition to adjudicating on numerous electrical accessories and appliances sent in for an expression of opinion. The proceedings of all these meetings have been carefully indexed for future reference when the work of revision commences, and will be made available to members of the Committee to aid them in redrafting any regulations which are at present considered to be ambiguous. The electric-supply authorities continue to evince a keen interest in seeing that the regulations are given effect to, and the work of administration of the regulations has been materially assisted by this co-operation of the electric-supply authorities. Amendments or additions to the following regulations were gazetted on 4th July, 1929 : — Electrical Supply: 46, 94, 106, 116, 189, and 205. Electrical Wiring: 66, 71, 76, 86, 90, 100, 133, 164, 179, 192, 200, 204, 223, 224, 225, 227, 228, 252, 281, Second Schedule Part 111, class (S) and class (T). INSPECTION OF ELECTRIC LINES. The periodic inspection of the electric lines throughout the Dominion has been maintained in conjunction with the inspections necessitated by the addition of new lines erected during the year. The following fifty-five supply authorities have made extensions to their electric lines during the year ending 31st March, 1929 : — Ashburton Power Board Poverty Bay Power Board Auckland Power Board Riccarton Borough Council Banks Peninsula Power Board Rotorua (Tourist Department) Bluff Borough Council South Canterbury Power Board Cambridge Power Board Southland Power Board Central Hawke's Bay Power Board Springs-Ellesmere Power Board Central Power Board Stratford Borough Council Christchurch City Council Taihape Borough Council Dannevirke Power Board Taranaki Power Board Dunedin City Council Tararua Power Board Franklin Power Board Taumarunui Borough Council Grey Power Board Tauranga Borough Council Hamilton Borough Council Te Aroha Borough Council Hastings Borough Council Te Awamutu Power Board Hawke's Bay Power Board Te Puke Town Board Horowhenua Power Board Thames Valley Power Board Hutt Valley Power Board Timaru Borough Council Invercargill Borough Council Waimairi County Council Malvern Power Board Wairarapa Power Board Manawatu-Oroua Power Board Wairoa Borough Council Marlborough Power Board Wairoa Power Board Napier Borough Council Waitaki Power Board North Canterbury Power Board W'aitemata Power Board Nelson City Council Waitomo Power Board New Plymouth Borough Council Wanganui-Rangitikei Power Board Otago Central Power Board Wellington City Council Palmerston North Borough Council Whangarei Borough Council.

Hawera Chalmers It is satisfactory to be able to say that the electric-supply authorities facilitate inspections, and almost without exception give prompt attention to the rectifying of any defects discovered as a result of these inspections. It is intended to arrange for more attention to be directed towards the inspection of wiring installations in public buildings and private residences, and to combine this with the periodic inspection of overhead lines. LICENSES ISSUED. The following water-power and electric-line licenses have been issued during the period from July, 1928, to July, 1929 : Waimea Electric Supply Co. (amendment), Bay of Islands Harbour Board, Uawa County Council (amendment), Hikurangi Town Board (2), Sullivan Bros. (Weheka), Westland Power Board (amendment), Manunui Town Board (2), Waipiro Trading Co. (Waipiro Bay), Golden Terrace Extended Gold-dredging Co., Lyttelton Borough Council (amendment), Ohakune Borough Council (amendment), Raetihi Borough Council (amendment), Westport Coal Co. (Granity). ELECTRICAL APPLIANCES BOARD. Pressure from the electric-supply authorities continues to be brought to bear on the Department for the setting-up of some authority with constitutional powers to prohibit the sale and use of unsafe electrical appliances to the public, but up to the present there is no legislative enactment to permit of this being done. ELECTRICAL FIRES. During the year 21 fires attributed to electrical causes were reported to the Department by electric-supply authorities. It is suspected that a good number of fires reported in the newspapers as originating from the use of electricity are wrongly classified as " electrical," and the various electric-supply authorities' engineers in New Zealand have been communicated with to make every endeavour to see that electricity is not blamed as the destructive agent unless it is definitely known to be the case. In this respect it has been suggested that supply authorities' electrical engineers should co-operate with local superintendents of the fire brigades by supplying the superintendent with E.S.R. 4 Forms, and the particulars furnished could then be verified by the local electrical engineer before signing same. WORK FOR OTHER DEPARTMENTS. This Department during the year has again been called upon to co-operate with other Government Departments —namely, the Mental Hospitals Department, in connection with electrifying the institutions at Seacliff, Porirua, Stoke, Avondale, and Tokanui; Health Department, Hanmer Sanatorium, extension of existing installation ; Tourist Department, in connection with electric supply for the new hostel at Milford Sound ; for the Cook Islands Department, work in connection with new generating plant for Niue Island ; and for the Department of External Affairs an inspection of the liydro-electric installation recently installed at Apia.

REGISTRATION of electrical wiremen. Tlxe Electrical Wiremen's Registration Act is now entering 011 its fourth year of operation, and has proved to be a very useful measure in protecting the public from dangerous work. It has also proved to be of assistance to the electrical-supply authorities in seeing that satisfactory work is being done, and has assisted them in their endeavours to prevent work being done by unskilled persons. The ease with which electrical wiring and apparatus can be extended, altered, or repaired has always proved a temptation to unskilled persons, consequently much unsatisfactory and sometimes positively dangerous work has been carried out in the past and still continues to a limited extent. That consumers will continue to tamper with their installations there is little doubt, and there appears to be no means of protecting such people from risk of the danger to life and property caused by work which is carried out contrary to the Electrical Wiring Regulations. The Act is designed to protect the person who is prepared to have the work done by skilled workmen, and the annual cost of administering it is little more than the cost of property destroyed in an average fire. The gain to the community so far as the elimination of destruction of property is concerned is obvious, while the immunity from danger to life is beyond estimation. The Act also has the effect of protecting the skilled wireman from unfair competition by men with little or no experience, and thus proves an incentive to the man who is prepared to devote his time to study in order to qualify. The Act is also designed to raise the standard of electrical-wiring work by providing that fully qualified men who have passed an examination of a standard not lower than that set by the City and Guilds of London Institute shall carry out the work. Provision had, however, to be made to register the wiremen who were working when the Act came into force, and, while probably the majority of these had passed an examination, the fact remains that work in the past was in a number of cases not done as well as could be desired nor as required by the regulations then in force. The power under the Act to. endorse a wireman's registration certificate or remove his name from the register for bad workmanshij) is having its eflect, and there is no doubt that the standard of work is improving. An amendment to the Act has given the Board power to remove an endorsement, and this will allow more freedom in making endorsements, as it was considered in a number of cases that an endorsement for life was too drastic a punishment, whereas one for a few years would meet the case. The Act and regulations were amended during the year to provide for several matters not included in the principal Act, and to make for better working in other directions. The members of the Registration Board are appointed for a term of three years, and as the term for the first Board expired on the 31st March, 1929, a new Board has, in accordance with section 3 of the principal Act, been appointed. The Board is now composed of three members of the previous Board and two new members. Provision was made in the regulations issued under the Act for the registers to be purged every three years, and notices were forwarded on the 31st March, 1929, to every registered electrical wireman informing him that if he wished to have his name retained on the register, application to that effect had to be made not later than the 30th June. To the end of June, 1929, there have been registered 317 Inspectors of Electrical Wiring, 2,779 electrical wiremen with full registration, and 60 electrical wiremen with limited registration, an increase of 53 Inspectors, 181 electrical wiremen with full registration, and 39 electrical wiremen with limited registration since July, 1928. In addition to the above registrations, 62 provisional licenses were issued during the year ended 30th June, 1929. Of the 2,779 electrical wiremen with full registration, 528 have been registered after passing the Board's examination. Nineteen prosecutions for working contrary to the Act have been taken during the year ended 30th June, 1929, and others are pending. Of the above prosecutions, one was taken against a wireman who had neglected to become registered ; nine cases were against unregistered persons ; four cases were against persons employing unregistered men; one against a contractor for employing an apprentice without supervision ; one against an apprentice for working without supervision ; one against a wireman for failing to produce his registration certificate for inspection ; one against a contractor for failure to notify intention to commence wiring-work ; and one against a wireman for connecting wiring with the source of supply before such wiring had been inspcctcd, tested, and approved. Fines and costs totalling £69 were imposed in the above cases. Up to the 30th June, 1929, 181 reports of breaches of the Act were received from the time the Act came into force. Figures for the yearly periods since the Act came into force are as follows: Year ended 31st March, 1927, fifty-two ; year ended 31st March, 1928, sixty-three ; year ended 31st March, 1929, fifty-four. A number of cases were not taken, as the evidence was insufficient to secure a conviction. Up to the 30th June, 1929, there have been 100 reports of bad workmanship from the time the Act came into force. The figures for the yearly periods are as follows: Year ended 31st March, 1927, seventeen ; year ended 31st March, 1928, forty-six ; year ended 31st March, 1929, twenty-seven. Of the cases reported during the year ended 30th June, 1929, the following action has been taken : One name was removed from the register, one provisional license was withdrawn, the certificates of sixteen wiremen were endorsed for bad workmanship, four wiremen were censured, five wiremen were cautioned, in one case the offence occurred before the Act came into force and no action could be taken, and in two cases the work was carried out by wiremen other than those first reported. Four Inspectors were reported to the Board for unsatisfactory inspections; of these, two were censured, one was referred to the supply authority concerned, and action in the other case is under review. Examinations were held during the year in September, 1928, and March, 1929. The results of the examinations are very unsatisfactory, and the indications are that the apprentices are not availing themselves fully of the facilities for technical instruction. Details of the examinations held will be found in the following tables.

APPENDIX E. FIFTH ANNUAL REPORT OF THE MAIN HIGHWAYS BOARD. The Main Highways Board to the Minister of Public Works, Wellington. Sir, — In accordance with the provisions of section 24 of the Main Highways Act, 1922, the Main Highways Board has the honour to submit its fifth annual report for presentation to Parliament through the Hon. the Minister. i The report covers the period from the Ist April, 1928, to the 31st March, 1929, though a few matters referred to are carried beyond the latter date for convenience and completeness of record. As stated, the report is the fifth annual report of the Board, but it is the first occasion on which the Board has had the pleasure of presenting such a document to Parliament through yourself. Introductory. The total expenditure by the Board for the year under review was £1,916,408, which is greater than the expenditure in any one year in the past. Of the total amount expended, £930,577 was expended from the Revenue Fund and £985,832 from the Construction Fund. Operations under the Revenue Fund involved the payment of subsidies on the maintenance of 10,403 miles of main highway, which length includes 6,651 miles of primary highways, and 3,752 miles of secondary highways declared during the year 1928-29. The expenditure from Construction Fund resulted in 223 miles 57 chains of highway being formed and widened, 185 miles 25 chains gravelled and metalled, and 198 miles 7 chains surfaced with bitumen and concrete. The year's operations so far as surfacing is concerned create a record, and a special outline of the work done and a general summary of accomplishments for the five years during which the Board has been operating is given in a separate section of this report. A total length of 9,482 ft. of bridges was erected, while engineering surveys were made over 339 miles of the highway system. A notable feature so far as construction is concerned is the substantial increase in the amount expended in the "South Island, which totalled, after excluding overhead charges, the sum of £229,820, as against the previous highest figure on record of £116,009. This substantial increase so far as the South Island is concerned is due to two factors —namely, the increase in the rate of subsidy on paving-works, and the authority vested in the Board empowering it to advance to the local authorities their share of the cost of works on main highways. Under this system the local authorities are enabled to accept an advance from the Board without taking a poll of the ratepayers, and may repay the amount out of the general revenue of the county. The County Councils in the South Island are taking considerable advantage of this system, and the Board is satisfied that it has been the means of getting the local authorities of the South Island to face the highway problem and proceed with necessary and desirable works. The amount which the Board is recommending for allocation to the South Island for construction purposes during the financial year now current shows a further substantial increase on the amount spent last year, but to enable this to be done it has been necessary to reduce the amount recommended for construction purposes in the North Island. This does not mean that the allocation is being increased in the South Island to the detriment of the North Island, because during the past five years the local authorities in the North Island have proceeded with construction and reconstruction schemes which absorbed the greater proportion of the Board's construction funds, while the South Island local authorities have been somewhat dormant in this respect and have not taken up the amount of construction-moneys which could have been made available for their purposes. A striking feature of the Board's construction operations during the year is the number of unmetalled sections of highway which have been metalled, and as a result of which important links in the highway system have been completed. A summary of achievements in this direction is given elsewhere in this report. The disastrous earthquake which took place in the Nelson and West Coast districts on the 17th June, 1929, caused extensive damage to main highways, and substantial expenditure will be involved in restoration. An outline of the damage and the steps being taken to restore the main highways are the subject of a further reference in this report. Main Highways Amendment Act, 1928. In the Main Highways Amendment Act passed during the 1928 session of Parliament authority was given to the Board to provide a greater proportion of the cost of the construction and maintenance of main highways than fixed by the original Act and its amendments, and also, if the Board is of opinion that such should be done, to provide the whole cost of works on any particular highway without contribution from the local authority. This power obviated the somewhat involved procedure

previously necessary. Extension of the Board's operations by the introduction of the petrol-tax, and the general policy adopted 'of paying a subsidy of £3 for £1 towards the cost of surfacing main highways adjacent to the large centres of population, made such a provision imperative. Another clause of importance related to the making of advances out of the Board's Revenue Fund to local authorities to enable such local authorities to meet their proportion of the cost of main-highway construction, reconstruction, and maintenance. Power to make advances to local authorities was originally vested in the Board in 1926, but doubt existed as to the power of local authorities to accept the advances. The clause in question cleared away such doubt, and also removed the limit of £50,000, which was the total the Board could advance under the 1926 Amendment Act. A further clause gave the Board power to contribute towards the cost of combined road and railway bridges. These bridges, generally speaking, are situated on railway property, and previously no power existed whereby the Board could expend money on what was legally a railway-line. Additional Main Highways. As outlined in last year's annual report, in consequence of the introduction of the petrol-tax in 1927 the Board took steps to declare an additional mileage of main highways. The total mileage of secondary highways declared was 3,752, which, together with adjustments to the primary system involving the declaration of an addtiional twenty miles, makes the total length of roads under the Board's jurisdiction 10,403 miles. In the case of practically every new highway the whole of the powers which are vested in the Board were delegated to the local authorities, such delegation being made not only in respect of the control of the highways, but also in respect of the construction and maintenance, the Board paying its subsidy on the expenditure incurred by the local authorities. A schedule is appended to this report giving the names and mileages of the various roads covered by the the recent declarations. The provisions of section 11 of the Main Highways Act, 1922, require that an annual review of highways shall be made by District Highway Councils, and in turn by the Board. In February of this year District Highway Councils were invited to make this review. In view of the declaration of such a substantial mileage of additional highways only a few months previously, and the fact that the Board was not in a position to gauge accurately its financial liability in respect thereof, District Highway Councils were informed that the Board proposed merely to take into account any alterations considered necessary in consequence of changed traffic conditions and the declaration of a limited mileage where special circumstances were shown to exist. Local authorities, however, in a keen desire to obtain the benefits of the Board's subsidies, made applications for over 2,000 miles of additional highways, and these in practically all cases were recommended by District Highway Councils. The Board has made several recommendations to you for the alteration of the routes of existing highways, but, in view of the heavy financial commitments which have been entered into, it does not propose to recommend any further roads for declaration at the present time. Main Highways controlled by the Boaed. Section 9 of the Main Highways Act, 1922, gives authority to the Board to delegate to local authorities the powers vested in it in respect of main highways, and in most cases this has been done. In certain cases, however, no such delegation has been made, while in other cases the delegation has been restricted to traffic control of the highways, the Board retaining the powers of construction, reconstruction, maintenance, and repair. The powers vested in the Board have been retained mostly in cases where the highway serves the ratepayers of a county to a limited degree only, where the Board itself is paying more than the ruling rate of subsidy for the time being in force, and where, for other reasons, the Board is in a position to exercise more efficient control and more economically execute the necessary works. The greater percentage of the mileage controlled by the Board consists of what can be classified as tourist highways, serving important tourist districts such as Rotorua, Tongariro National Park, the west coast of the South Island, and the southern lakes district. The mere fact that the Board controls any particular highway does not, in itself, mean that the local authorities are exempt from providing a proportion of the expenditure incurred in their upkeep. Finance. The actual contributions to the Board's Revenue Fund from external sources for the year 1928-29 amounted to £1,303,178. The tabulation hereunder shows how this amount is made up. The income from similar sources during the past four years is also shown. A feature of the table is the variation which has taken place from year to year in the amount of tire-tax received by the Board. Thus in 1925-26, when there were 136,715 motor-vehicles using the roads of the Dominion, the return from tire-tax was £223,699, being approximately £27,000 more than the return from tire-tax in 1928-29, when there were 56,000 more motor-vehicles on the roads. While there has been a 40 per cent, increase in the number of motor-vehicles, there has been a 12 per cent, reduction in the return from tire-tax. Again, if the average amount collected per annum during the four years prior to 1928-29 is taken, it is found to be greater than the amount collected during 1928-29. Although during this period there has been a reduction in the price of tires, which would have the effect of reducing the amount of Customs duty, the figures afford striking evidence of the improvement in the highway system. No doubt there has been an improvement in the design of tires, but the better standard of road-surface brought about by the expenditure of special motor-taxation must be recognized as the outstanding reason.

D.—l

The actual relationship between the number of motor-vehicles using the roads and the amount collected in tire-tax is illustrated in graph below.

The total income from external sources' —£1,303,178 —is almost double the amount received in the previous year, for the reason that it is the first complete year during which the petrol-tax has been collected. Eliminating the transfer of £35,000 from the figure just quoted, the total direct taxation received by the Board from motorists was £1,268,178. The total amount of petrol-tax collected by the Customs Department during the year was £851,366, and of this amount £49,135 was refunded to persons entitled to exemption under the Motor-spirits Taxation Act, making the net amount received £802,231. Charges for collection and for making refunds amounted to £8,303, and of the balance £730,414 was credited to the Main Highways Revenue Account, and £63,514 was paid to cities and boroughs of a population of more than 6,000, the allocation being made on a population basis and approved by yourself. At the time the introduction of the petrol-tax was under consideration by Parliament, it was estimated that the net yield to the Board for 1928-29 would be £754,000, and the Board's programme of works was drawn up on this basis. It will be noted that the receipts were actually a little under the estimate. For the year ended 31st March, 1929, the appropriations and expenditure under the Revenue Fund were as follows :—

In consequence of the authority conferred on the Board by last year's Amendment Act enabling it, at its discretion, to increase the rate of subsidies, the Board, as from the Ist April. 1928, increased the general maintenance subsidy from £1 10s. for £1 to £2 for £1. This is the third occasion on which by reason of its increased revenue the Board has been able to improve the conditions of the maintenance subsidy. In 1924, on the declaration of the original highway system, the Board paid a subsidy of 10s. for £1; in 1925 this was increased to £1 for £1 ; eighteen months later, in 1926, a further increase was made from £1 for £1 to £1 10s. for £1 ; while the present subsidy is £2 for £1. Thus the proportions found by the Board and the local authorities in 1924—i.e., one-third and twothirds respectively—have now been reversed. The subsidy of £2 for £1 applies to the additional highways declared in 1928 as well as to the original system. In addition to the increase in the rate of subsidy for maintenance, the Board also approved an increase in the rate of bridge subsidy. The original Main Highways Act fixed the bridge subsidy at £1 for £1, except that in any special case where a bridge was situated on a Government road the Board had power to grant more liberal terms. Realizing that the cost of bridges, particularly the large structures, falls heavily on local authorities, the Board in 1925 obtained authority to increase the bridge subsidy. A sliding scale was adopted, and the rate of subsidy increased with the cost of the bridge, the rates of subsidy being one-half of the cost up to £10,000, three-fifths of the cost exceeding £10,000 but not exceeding £20,000, and two-thirds of the cost exceeding £20,000. On bridges involving expenditure up to £10,000 the Board now, as a general rule, pays a subsidy of £2 for £1, and on expenditure above £10,000 £3 for £1. In special cases these rates may be varied. An analysis of the expenditure by the Board and by local authorities on actual maintenance, as distinct from interest on loans and other overhead charges, is shown in the tabulation below. The tabulation has been subdivided to show, firstly, the expenditure on the original system of main highways, secondly, the expenditure on the additional main highways declared in 1928, and, thirdly, the expenditure on the whole system.

It will be noted that on the primary highway system the local authorities found £224,092, as compared with £269,065 last year —a reduction of £44,973. This is the first occasion on which the amount contributed by local authorities towards the cost of maintenance of the original highway system has shown a substantial reduction, and is accounted for by reason of the fact that, the actual cost of maintenance having stabilized to some extent, the increase in the Board's subsidy from £1 10s. for £1 to £2 for £1 has given direct relief to the local authorities. It is significant that the amount of the reduction, so far as the original highway system is concerned, forms more than two-thirds of the total amount provided by the local authorities for the maintenance of the secondary highways. The total amount provided by the local authorities for the whole of the highway system of 10,403 miles — namely, £284,526 —is only £8,000 more than the local authorities provided towards the cost of maintenance of the original highway system, then 6,391 miles, in the peak year 1926-27. The following tabulation shows the amount which has been provided by the Board and the local authorities for expenditure on the construction and maintenance of main highways during the five years which the Board has been in operation.

The figures in the above tabulation do not include indirect charges such as supervision, interest, and other overhead charges. An analysis of the actual expenditure on maintenance in each Island as compared with the number of motor-vehicles in each Island at the 31st March of each year since the inception of the main-highways scheme gives the following results, expressed in percentages of the Dominion's totals : —

These figures reveal the fact that the percentage of expenditure on maintenance of the main highways in the North Island each year has been greater than the percentage of motor-vehicles in that Island. This is due to two factors —namely, that the physical conditions of the North Island require a heavier expenditure to maintain the roads up to the same standard than is the case in the South Island, and, in addition, the North Island has by far the greater percentage of heavy vehicles. The tabulation also shows that the proportion of the vehicles in the North Island has increased annually since 1924. The proportion of maintenance expenditure in the South Island is greater than the proportion of the Board's revenue received from the South Island. In accordance with the direction contained in section 21 of the original Act, and following on the Board's resolution passed in May, 1925, an apportionment of the tire-duty and license fees for the year ended 31st March, 1929, has been made between the two Islands in proportion to the number of motor-vehicles registered in each Island on that date. No statutory provision exists requiring an apportionment of the proceeds from the petrol-tax between the two Islands, but the Board is of opinion that the most equitable method of distribution of this tax is according to the actual consumption of motorTgpirit jn each Island. As a guide to the basis on which the distribution should be made, the Board recently obtained from all oil companies figures showing the distribution of the petrol as between the two Islands. The information obtained shows that during the calendar year 1928 approximately 72 per cent, of the motor-spirit imported was consumed in the North Island and approximately 28 per cent, in the South Island. No adjustment has been made on these percentages to take account of rebates because the definite information is not available, and, in any case, it appears probable that the rebates in each Island will bear a similar proportion to one another as the amounts of petrol used. Moreover, the proportion of rebates is so small that a very considerable error, in their proportions would not materially affect the proportion of the totals. In making the apportionment the interest on moneys borrowed for construction work in each Island has been charged against the revenue allocation to each Island, and other adjustments in connection with interest on accumulated balances have been made. On the assumption given above, the balances to the credit of the North Island and South Island respectively on the 31st March, 1929, are £209,261 and £408,869.

This transfer, in accordance with arrangements made, was of a temporary nature only, the amount to be repaid to the Revenue Account out of loan-money when required. Actually, no repayment was made during the financial year to which this report relates, so that the account of each Island has yet to receive credit for the amount temporarily transferred. In accordance with arrangements made by the Minister of Finance, a sum of £150,000 is being repaid to the Revenue Account in the financial year now current. In addition to the above temporary transfer, a sum of £350,000 was transferred from the Revenue Fund to the Construction Fund during the financial year 1928-29, but no repayment is to be made in this case. This transfer was made, in accordance w T ith the announcement on the introduction of the petrol-tax, to meet the extra subsidy—i.e., £3 for £I—being1—being paid by the Board towards the cost of paving schemes adjacent to the large centres of population, the subsidy payable on construction work in small boroughs and the increased bridge subsidy. It was originally intended to confine the payment of an extra subsidy on expenditure on paving the highways adjacent to centres of a greater population than six thousand persons, but it was found possible, on account of the funds which had accumulated to the credit of the South Island, to extend the five-year programme of pavingwork to include a greater length of the trunk highway between Picton and the Bluff. Accordingly negotiations were opened up with the local authorities to decide upon a schedule of works covering the above period, and the results were decidedly satisfactory. It was pointed out in last year's report that because the large paving schemes and other construction rendered possible by the petrol-tax could not commence contemporaneously with the collection of such tax it was anticipated that there would still be a considerable accumulation of funds at the close of the financial year, 31st March, 1929. Actually this proved to be the case, but as a result of the extension of paving schemes referred to above heavy construction and surfacing programmes are now in hand, and the amount expended on construction works since the close of the financial year to which this report relates is heavier than the amount expended in any similar previous period. Also, a number of further paving contracts have been let during the past few months, and these will be in full operation in the summer construction season. Already a sum of £400,000 has been transferred from the Revenue Fund to the Construction Fund during the financial year now current, and it will be necessary to transfer a further sum of at least £350,000. The transfer of these amounts out of the Revenue Fund, together with the increasing charges on this fund, will substantially reduce the balance in this account at the end of the year. For the year ended 31st March, 1929, the appropriations and expenditure under the Construction Fund were as follows :—

The tabulation has been subdivided to show, firstly, the net expenditure on the original system of main highways; secondly, the net expenditure on the additional main highways declared in 1928; and, thirdly, the net expenditure on the whole system.

When the above figures are compared with the figures for 1927-28 it will be found that there has been a reduction of £72,000 in the amount contributed by the local authorities towards the cost of construction works on the original highway system, and the whole of that reduction has been in the .North Island. The reduction has taken place despite the fact that the Board's expenditure is greater than on any previous occasion, and is a direct result of the payment of increased subsidies on paving of highways adjacent to the larger centres of population as well as on bridges. Furthermore, in the early stages of the Board's operations a large number of local authorities in the North Island borrowed substantial sums for reconstruction of main highways on a £l-for-£l basis. . Most of this borrowed money was spent prior to the financial year 1928-29. Review op Past Operations. The Main Highways Board has now been operating for a period of five years. The time therefore appears opportune for the presentation of a short summarized review of its activities. The annual expenditure on main highways since 1924 has increased very substantially. It is proposed in a general way to analyse the increasing expenditure, and compare it with the development in motor transportation and with the expenditure being incurred on the main-highway systems in other countries. The following tabulation shows the amount of construction work accomplished on main highways since the Board commenced to function:—

An examination of the above figures discloses the steady progress which has been made. The question is sometimes raised as to whether highway development in New Zealand is not proceeding at too great a rate. Highway development is merely the result of development of motor transportation, therefore comparisons between the two should show some relationship. One of the main functions of the Main Highways Board is to provide such types of roads as will withstand the destructive effects of motor-vehicles, provide a reasonably smooth running-surface, and, where the circumstances warrant, eliminate the dust nuisance. These dust-free types range from a tar-sealed macadam surface to a Portland-cement concrete pavement. The total rural mileage of such improved surfaces in New Zealand in 1924 was 325 miles. As the result of the operations under the Main Highways Act, the length has been increased to the present figure of 830 miles. The following graph shows the relation between the total motor-vehicles using the roads and the mileage of improved surfaces.

It will be noted that the advances made in road-construction have not been disproportionate to the use made of the roads by motor-vehicles. In view of the recent substantial increase in motor-taxation it is also interesting to compare the expenditure by the Board with the number of motor-vehicles using the roads. The diagram below gives the information in graphical form. The expenditure shown is the net total provided from the Board's funds on actual construction and maintenance, overhead charges, interest on loans, &c., being omitted.

The graph shows that the expenditure has not been inconsistent with the development of motor transportation. Also it is evident that if the petrol-tax had not been imposed in 1927 highwayactivities would have lagged considerably behind motor development. The following graph in this connection is also of interest.

The above diagram shows the relation between the net expenditure on highway construction and maintenance, and the increase in traffic which has taken place over the same period on a typical rural main highway. For comparative purposes the information concerning horse-drawn traffic is also shown. In Victoria the Country Roads Board, the counterpart of the New Zealand Main Highways Board, has been in operation about sixteen years. In New South Wales the Main Roads Board has been in operation for about four years. It is of interest to compare the annual expenditure on main highways in these two States with the corresponding amount for New Zealand. The following tabulation shows the latest figures, together with the unit expenditures per motor-vehicle and per head of population : —

The figures per head of population are in remarkably close accord, while the expenditure per motor-vehicle in New Zealand is very substantially lower than in the two Australian States.

A similar tabulation has been prepared showing the same information for eleven of the American States, the populations of which range from 800,000 to 2,500,000, a range which includes the populations of the Australian States and New Zealand. The figures relate to the year 1927.

The average expenditure on highways per head of population for these eleven States is £1 6s. 6d. This figure is a shade over the New Zealand figure and is almost exactly the average between Victoria and New South Wales. Again it is obvious that if the petrol-tax had not been imposed in New Zealand highway expenditure would have lagged considerably behind that of our neighbours as the expenditure per head of population in this country for the year 1927-28 was only 14s. 7d. Although the above information goes to show that main-highway activities have just reached a stage comparative with what is being done in other countries, it is not desired to give the impression that roading development in New Zealand as a whole has lagged behind corresponding development elsewhere. The diagram below shows the percentage of total roads surfaced and unsurfaced in the United States of America and New Zealand. It also shows the percentage of improved surfaces, including all types, from tar-sealing upwards.

Diagram No. 1

The diagram disclose.-* that as far as the proportion of all-weather surfaced mileage is concerned New Zealand is many years in advance of the United States, but that New Zealand is well behind the United States in the provision of the improved surfaces required specially for motor-traffic. The latter result is largely accounted for by the fact that the traffic density per mile of road on the arterial roads of the United States of America is very much greater than in New Zealand. Diagram No. 2 discloses the manner in which the main arterial systems in each country are surfaced. For the purposes of this comparison the main arterial system is assumed as being the most important 10 per cent, of the total road-mileage.

Again it will be seen that New Zealand lags behind in the provision of improved dustless surfaces. The popularity of Portland-cement concrete pavements in the United States of America is brought out, this being mainly due to the enormous traffic which is carried on a large mileage of the rural highway system, and which justifies the construction of such expensive surfaces. The above review appears to support the following conclusions : (1) That highway development in New Zealand is merely keeping pace with the development of motor transportation ; (2) that the rate of expenditure on highway activities has just reached a figure which is remarkably close to the rates of expenditure in other new countries where the conditions of national development and the development of motor transportation are somewhat similar to those in New Zealand. The Main Highways Board does not desire undue exaltation of the importance of highways, or that highway development shall be at the expense of other necessary activities, but the problem to be faced is that, so long as transportation over the highways is necessary, expense is inevitable whether the roads are good or bad. Probably the expense is greater if the roads are bad, through increased operating-costs, which tax the public just as certainly as the ordinary fiscal methods. Construction. The construction work carried out or subsidized by the Main Highways Board may be discussed under three headings —(1) The closing up of unmetalled gaps in the main-highway system, a work to which the Board has consistently applied itself ever since it commenced to function ; (2) the paving of sections of highway which carry traffic beyond the capacity of the ordinary gravelled or metalled road, which work has been given considerable impetus since the imposition of the petrol-tax ; and (3) the construction and replacement of bridges. With regard to the first heading—i.e., the closing of unmetalled gaps —it was remarked in last year's report that the additional finance available to the Board would assist very largely in completing existing gaps in the system. Achievements in this respect have been gratifying alike to the Board and to the general public. The most important connection of this nature yet to be accomplished is that between Auckland and Whangarei. This work will involve a very heavy expenditure over a number of years, and the Board was loath to commence serious operations until it was in a position to provide a substantial annual appropriation for the project. The additional revenue enabled a commencement to be made during the year under review, and last summer a great deal of work was accomplished. Upwards of six hundred men were employed during the working season. Such activity on one roadwork has been unparalleled in the history of the Board, and indeed, it is believed, in the history of the Dominion. An all-weather connection was established before winter between Auckland and Waiwera. Metalling was linked up on the highway between the Townships of Kumeu and Albany, connecting the east and west coast of the North Auckland Peninsula. A work of great importance to the Bay of Plenty has at last been completed —namely, metalled access to the Waikato via the Kamai Hill and Matamata. This accomplishment also provides the first all-year-round route from Tauranga to Auckland. Another notable achievement has been the linking-up of Rotorua with the rest of the North Island by a metalled surface through the notorious Mamaku Bush. This work has revolutionized winter transport to the thermal region. The King-country (including the other great tourist resort of the North Island, the Tongariro National Park) has also been connected up for the first time with the rest of the North Island by metalled roads. It is a coincidence that two connections should be accomplished in the one season —- the direct connection to Wanganui via the Parapara Road, and the connection between Ohakune and Wellington via Taihape. On the former work a spectacular programme was carried out in a very short

working season. At tlie beginning of February, 1929, a gap of 10$ miles of clay surface existed on the Parapara Road, yet this gap was entirely closed by the end of April. Thus in record time was completed the final phases of a work which the people of Wanganui have strongly advocated for a period of forty years. The Kawhia district was connected up with the rest of the North Island by a metalled road. On the Oliura Road, the Township of Whangamomona and its surrounding district were provided with all-weather access to Taranaki for the first time in its history. Another work for which motorists have been pressing for a long time is the connection between Gisborne and Opotiki. The Board has concentrated on this connection during the past two years, and succeeded in laying a base course of metal right through before the winter. The completion of this work will give Gisborne district its third important connection since the Board commenced operations, so that, as far as road transport is concerned, Gisborne can no longer complain of being isolated. Another work on which the Board has concentrated during the past two years has been the main thoroughfare through the middle of the North Island, known as the Te Kuiti - Bulls via Taumarunui Main Highway. During the past working season a very large amount of work was accomplished between Te Kuiti and Taumarunui, and next winter light motor-vehicles should be able to traverse the whole of this highway without inconvenience. The work of the Board under the second heading above mentioned—i.e., the paving of sections of highway carrying heavy traffic —has also progressed in a very satisfactory manner. It will be remembered that when the proposal for the imposition of the petrol-tax was first placed before Parliament an announcement was made indicating how the proceeds of the tax were to be used. In particular, a substantial proportion of the tax was to be devoted to the payment of higher subsidies towards the cost of paving schemes where the traffic was such that a higher and more costly type of surface was necessary. Following upon this announcement, schemes were prepared around all the more important centres of population. The details of these schemes were decided upon after collaboration with the local authorities and automobile associations. The development of this phase of the Board's work has given a great impetus to expenditure in the South Island, where a number of important schemes have been commenced . The changed attitude in the South Island has also been largely brought about by the use of the powers given to the Board to advance money to local authorities under the Main Highways Amendment Acts of 1926 and 1928 in circumstances where it considers this advisable. One unavoidable result of the speeding-up of operations in the South Island will of necessity be the retardation to some extent of works in the North Island, where the local authorities for the past five years have received a heavy proportion of the Board's construction funds. The disinclination of the authorities in the South Island to proceed with schemes of construction in the past has not, of course, affected the distribution of the Revenue Fund, details of which are submitted elsewhere in this report. The class of work being carried out under the paving schemes ranges from bituminous surface treatment of macadam and gravel roads to the construction of Portland-cement concrete pavements. No less than 198 miles of dustless roads were constructed during the year, made up as follows : Tar and bituminous surface treatment, 122 miles ; bituminous macadam (penetration), 51 miles ; bituminous concrete, 14 miles ; Portland-cement concrete, 11 miles. When it is pointed out that the total rural mileage of dustless roads in New Zealand at the 31st March, 1928, was about 639, it will be seen that in one year the operations under the Main Highways Act have increased that mileage by about 30 per cent. While this accomplishment is most gratifying,, it is nevertheless necessary to realize the very small proportion which these figures bear to the total length of roads under the control of the Main Highways Board —namely, 10,403 miles. At the present rate of progress it would take twelve years to provide dustless surfaces on only a quarter of the length of the highway system, and by that time a substantial length of the cheaper surfaces now being laid down would have reached or would be nearing the end of its useful life. If a more lasting material, such as concrete or bituminous concrete, were adopted universally as a surfacing-material on the highway system it would take between thirty and forty years before one-quarter of the present highway system could be surfaced, and long before the expiry of this period a substantial mileage of the work would have reached the end of its useful life as a surfacing-material. Most of the paving-work during the past year has been carried out by contract, this being in accordance with the Board's general policy since it commenced operations. In a number of cases alternative tenders have been called for Portland-cement concrete and for bituminous concrete, and, generally speaking, the prices have been very satisfactory. In Hawke's Bay and Canterbury, in particular, good tenders have been received for Portland-cement concrete construction, the figures ranging from £5,800 per mile to £6,800 per mile for an 18 ft. concrete road 9 in.-6 in.-9 in. section with, in some cases, 3 ft. bituminous shoulders. These prices are considerably below prices for similar work in the Auckland District, where aggregate is more costly. Another type of paving for which a number of contracts have been left is single-course bituminous concrete. Pavements of this class, and of a thickness of 2f in., are being laid, where aggregate is reasonably cheap, at a cost of between ss. and 6s. per square yard, or about £3,000 per mile, for an 18 ft. pavement. It is now proposed to discuss the third division of highway construction — the erection and replacement of bridges. Since 1924, on those roads under the control of the Main Highways Board, an aggregate length of nearly 6 miles of bridges has been built, yet only the fringe of the bridge problem has really been touched. Practically all the large bridge proposals are merely replacements, and consequently are not spectacular from the point of view of the general public, yet the necessary finance involves the Board in very heavy commitments. Moreover, much of the expenditure is impossible of postponement, as many of the existing structures are vitally important but very weak links in thejnaain arterial routes.

In spite of the great deal of good work accomplished during the past five years, the other activities under the Highways Act, in the way of widening and improvement of the alignment, grades, and surfaces generally, merely draw more pointedly the attention of the road-user to the inadequacy of hundreds of bridges on the main thoroughfares. Such inadequate structures may be classified under five groups —(1) Bridges which are structurally unsafe ; (2) bridges which are too light for modern traffic ; (3) bridges which are too narrow for modern traffic ; (4) bridges which are on poor alignment ; (5) bridges which are unsatisfactory and often dangerous because of combined road and railway use. The time has arrived for a methodical investigation of the condition of all our important bridges, particularly with regard to headings (1) and (2). The enormous increase in volume of traffic during recent years, and the greatly increased speeds of heavy vehicles, are proving very trying to many of the older wooden structures. Comment is sometimes made on the great number of wooden bridges which exist in New Zealand, and on the desirability of their early replacement with structures built of so-called permanent materials. The following extract from the last biennial report of the Division of Highways in California, published this year, gives food for thought: — " There has been an increased number of redwood and creosoted Douglas-fir bridges built during the past biennium. For several years the great majority of short-span bridges on the State highways have been built of concrete. They were built for permanent structures, but the large, unlooked-for increase in traffic and the much higher standard of alignment now in use on the connecting highways have rendered many of these bridges, with narrow roadways and poor alignment of approaches, either dangerous or very unsatisfactory for present-day conditions. Where the bridges are narrow, but on good alignment, the defect can be remedied by widening the structure, and this has been done in many cases ; but where the alignment of the approaches is poor it frequently happens that this cannot be corrected without abandoning the existing bridge altogether. It has thus developed that many of these so-called permanent bridges have become obsolete in less than ten or fifteen years. Assuming a thirty-five-vear life for a creosoted fir or redwood timber bridge, and neglecting the fire hazard, the timber bridge will in most cases be slightly cheaper in the long-run than a permanent concrete structure, the saving in first cost being more than enough to rebuild the timber structure at the end of thirty-five years. The disadvantages of the timber structure are the fire hazard and the inconvenience to traffic at the time of rebuilding. When the available funds for any bridge project are limited, there is therefore no loss in economy in building a timber structure, and where there is any doubt as to the permanency of location for a crossing a timber bridge is obviously the economical type." To give an idea of the immediate bridge programme, the following list shows some of the more important structures which are now either under way or will have to be put in hand in the next year or so, and for all of which the plans are completed or are well advanced : — Approximate Name.

In addition to the above list, there are hundreds of minor structures requiring attention, involving the expenditure of many thousands of pounds. Other problems to be faced are the difficulties experienced on such large and important combined road and railway bridges as the Rakaia Bridge in Canterbury. Any reasonable solution of these difficulties is bound to involve the Main Highways Board in very heavy charges. In regard to standards of construction, and this applies not only to bridges but to roads generally, satisfactory progress has been made during the year under review. Local authorities continue to appreciate the necessity for complying with the requirements of the Board, particularly as regards improved alignment and visibility. The increasing traffic, and the increasing speed of that traffic, require frequent modification of these standards, and in approving proposals an endeavour is made to anticipate in a reasonable manner the requirements of the future. An indication of the Board's attitude towards these matters is shown by the decision during the past year to increase the width of first-class bridges on the most important arterial roads to 20 ft. between kerbs, instead of 18 ft. as heretofore. In special cases widths up to 24 ft. are approved. The Board has also requested local authorities, in submitting proposals for short bridges of 12 ft. span and under, to make the trafficable width of the bridge the same as the width of the adjacent road-formation. During the current year it is hoped to issue further data regarding standards for the assistance and information of local authorities. Such information will include a number of typical modern specifications for various classes of highway-construction. ' Maintenance. With a few exceptions, the main highways have been well maintained throughout the year. In one or two cases the Board has been reluctantly forced to use the special power conferred on it by statute, with beneficial results to the travelling public. It was remarked in last year s report that the maintenance expenditure appeared to be stabilizing to some extent, due, no doubt, to the adoption of better methods and the use of suitable maintenance plant, and, to a certain degree, to the increase in the mileage of high-class pavements. The figures for the year under review show similar features. The increase in maintenance cost per mile on the primary highway system of 6,651 miles is substantially lower than in previous years, the average cost per mile per annum since 1924 being as follows : 1924-25, £51-7 ; 1925-26, £73-2 ; 1926-27, £111-9 ; 1927-28, £119-9 ; 1928-29, £125-2. It will be seen that the increase in maintenance cost during 1928-29 has amounted to only 4-4 per cent, over and above the cost for the previous year, whereas the number of motor-vehicles actually using the roads has in the past twelve months increased by 14 per cent. With regard to secondary highways, a total length of 3,752 miles was maintained at the average cost of £55-5 per mile, the figure for the North Island being £66-2 per mile, and for the South Island £43-8 per mile. The total sum found by the Board on secondary highways, as already pointed out, amounted to £147,873, the whole of which is a direct relief to local authorities. Elimination and Improvement op Railway Level Crossings. The following eliminations were completed during the past year :— Gisborne-Opotiki via Motu Main Highway : Two crossings at Rakauroa. Wellington-Napier via Wairarapa Main Highway : Two crossings at Matahiwi Hill; crossing at Piripiri. Auckland-Wellington via Taranaki Main Highway : Crossing at Hawera. Waipara-Kaikoura via Culverden Main Highway : Crossing at Weka Pass. Dunedin-Christchurch Main Highway : Crossing at Tumai. With regard to the problem of the level crossing generally, the Board has, during the past year exchanged views with the Railway Department. Both authorities are prepared to continue to make reasonable sums available for elimination and improvement of level crossings, but the cost of elimination is so great that only a very few crossings can be dealt with annually. It is agreed that it would be advisable to consider the question of diverting a substantial proportion of the capital expenditure towards the carrying-out of improvements to visibility and the installation of automatic warning-devices at a large number of railway-crossings. Such a change in policy during the next year or two would confer much greater immediate benefit upon road-users than by devoting the whole of the available funds to elimination work. There are a great number of crossings throughout the country where the expenditure of a moderate sum could be devoted to the removal of obstructions on railway property, on the roadway and on private land, resulting in greatly improved visibility and a proportionate reduction in danger to the road-user. The attitude of the Main Highways Board towards these suggestions as far as main highways are concerned can be summarized as follows :— (1) Where it is necessary for the improvement of the view at a crossing to remove obstructions 011 railway property, the Board is unable to .make any contribution. . ( 2 ) Where it is necessary to remove any obstruction on the roadway for the purpose of obtaining an improvement to visibility, the Board will, in conjunction with the local authorities, provide the necessary cost.

165

D.—l

(3) In cases where it is necessary to take private land for the purpose of carrying out improvements to visibility, the Board is prepared to bear half the cost with the Railway Department. The Board will negotiate with the local bodies in respect to any contribution which it thinks should be made by them. (4) The Board is prepared to bear 50 per cent, of the cost of installation of automatic warningdevices and 50 per cent, of the annual cost of maintenance of same. It is also considered necessary by both the Railway Department and the Main Highways Board that there should be power to enter upon private property for the purpose of removing obstructions adjacent to level crossings without going to the extent of taking the land, but at the present time there is no enabling statutory authority. Advances to Local Authorities. Section 2 of the Main Highways Amendment Act of 1926 vested the Board with authority to advance moneys by way of loan to local authorities for highway purposes. The Act limited the total amount to be advanced to a sum of £50,000. The section in question, however, was practically inoperative, for the reason that doubt existed as to whether local authorities in certain cases could accept advances from the Board. Such doubt, however, was cleared away by the Main Highways Amendment Act of 1928, which, in addition, removed the limit of £50,000. The maximum period of any loan is fixed by the Act at ten years. The result of the 1928 Amendment Act is that local authorities are taking considerable advantage of their powers to obtain advances from the Board, mainly in connection with paving schemes on the arterial highways. Particularly is this the case in the South Island, where local authorities are averse to borrowing under the usual procedure. In fact, the Board is satisfied that it is only by reason of the powers conferred by this clause that it has been able to obtain the co-operation of the local authorities of the South Island in connection with the more costly forms of highway improvement. It should here be explained that the powers conferred on local authorities are such that it is unnecessary to take a poll of the ratepayers to obtain an advance, but the Board desires to make it clear that local authorities, on this account, are not likely to embark on injudicious expenditure. In the first case, the powers to make an advance are confined to the Main Highways Board, and no private person or other lending authority can lend money to local authorities under this section. Any amounts advanced to local authorities can be used for highway works only, and therefore the Board itself has a direct interest, in that it is required to pay a subsidy on the cost, so that in considering any application for an advance the Board satisfies itself as to the soundness of the work not only from a local-authority point of view, but also from a highway point of view. In the matter of the period of the loan the Board has due regard to the life of the asset, and in all cases is careful to allow an ample margin. All loans are made on the instalment repayment system, the local authority being required to make equal annual payments, which include interest on the amount for the time being outstanding and part repayment of principal. Traffic-control. The Board has on numerous occasions pointed out the necessity for an efficient system of trafficcontrol, particularly with regard to heavy traffic. The Board is satisfied that owing to non-enforcement of the heavy-traffic regulations much greater damage than necessary is caused to highways by reason of overloading and speeding, with the inevitable result of higher maintenance charges. The Board recently appointed a Traffic Inspector to regulate traffic on the main highway between Auckland and Hamilton, and reports available have fully confirmed the opinion expressed above. In consequence the Board has suggested to local authorities that certain groups should combine for the purpose of administering the traffic regulations, and in a number of cases this suggestion is being adopted. Earthquake Damage. Serious damage was caused to the main highways in the Nelson and West Coast district by the disastrous earthquake which took place on the 17th June, 1929. Communication by road between Nelson and the West Coast was cut off by the heavy slips which took place in the Buller Gorge between Murchison and Lyell, while highway communication between Westport and Karamea was also entirely cut off. Minor damage was caused on ether highways, but in these cases communication was restored within a comparatively short time. From the first inspection made of the Buller Gorge it was evident that it would take a considerable time to restore the highway—in fact, some doubt existed at first as to whether it could be reopened— and accordingly immediate steps were taken to provide for traffic by reconditioning the road from Murchison to Reefton via Maruia. In view of reports made from later inspections, the Board has decided to reopen the main road, but as the whole length of highway affected will have to be resurveyed, and also in view of the fact that it would be unwise to commence reconstruction until the country has more or less stabilized, it may be a year to eighteen months before traffic can again travel via this route. In the meantime traffic will require to utilize the Murchison-Maruia-Reefton route, although it involves an extra sixty-three miles in travelling from Nelson to Westport and over twenty miles additional to the rest of the West Coast. The damage between Mokihinui and Karamea is extensive, and of such a nature that it appears, although a final examination has not been made, that this section may have to be abandoned and a new road constructed along the coast.

Purchase of Plant. The policy of purchasing and hiring plant on the hire-purchase system, to local authorities h as been continued. The total value of plant purchased on this system to the 31st March, 1929, amounted to £106,324. The following statement shows the plant ordered and hired to local authorities from the 31st March, 1928, to the 31st March, 1929, the amount involved being £30,617 : Power graders, 15 ; ordinary road-graders, 3 ; crushers, 2 ; granulators, 3 ; motor-lorries, 12 ; rollers, 3 ; tractors, 4 ; bitumen-boilers, 3 ; sprayers, 3 ; elevators, 3 ; conveyer, 1 ; electric winch, 1 ; &c. In addition to the above, the Board purchased the following plant for its own use, at a total cost of £33,202 : Power graders, 8 ; ordinary road-graders, 3 ; road-rollers, 12 ; motor-lorries, 12 ; crushers, 6 ; air-compressors, 10; air-receiver, 1 ; tractors, 5 ; bitumen-boilers, 9 ; sprayers, 5 ; oil-engines, 2 ; concrete-mixers, 2 ; sweepers, 2 ; motor-car, 1; motor-cycle, 1 ; elevators, 2 ; roadmaintainer, 1 ; trailers, 2 ; &c. The Board has continued to encourage and urge the use of modern plant, particularly on highwaymaintenance. With a view to ascertaining the increase in roadmaking plant in the possession of County Councils, statistics were recently collected showing the numbers of the more important items of roadmaking plant being used throughout the country. Similar information was obtained in 1924. The following statement shows the two sets of figures :— 1924. 1929. Road-rollers .. .. .. .. 67 108 Crushers .. '.. .. .. .. 134 165 Lorries .. .. .. .. .. 173 238 Graders .. .. .. .. .. 419 546 Tractors .. .. .. .. 15 101 Bitumen-sprayers .. .. .. 6 34 Bitumen-boilers .. .. .. 7 55 The plant now being used by the County Councils is approximately one quarter of a million pounds greater in value than the plant being used five years ago. Of this amount approximately £100,000 has been advanced by the Main Highways Board, and it is safe to say that, if it had not been for the Board's system of hire-purchase, plant to the value of this amount would not have been placed in operation. The replacement of horse traction by motor-vehicles is revealed in the large increase in the number of tractors, from 15 in 1924 to 101 in 1929. The development in the use of tar and bituminous surfaces is disclosed in the increase in the number of bitumen sprayers and boilers. Testing of Highway Materials. The Petrological Laboratory has continued to carry out the standard tests on roadmakingmaterials. Table 6 shows the rock-tests carried out during the year. In addition, a large number of granulometric analyses of gravels and sands were undertaken. Several special geological investigations in connection with highway matters were carried out. The testing of samples of tar, road-oil, bitumen, bituminous emulsions, and bituminous concrete was efficiently undertaken as usual by the Dominion Analyst, Wellington. EXPERIMENTAL WORK. As a result of a preliminary experiment carried out last year with the oil treatment of a section of pumice road in the Rotorua District, a further length of 51 chains on the Rotorua-Taupo Main Highway and a length of 90 chains on the Te Ngae - Paengaroa Main Highways were laid down during the summer. The results so far obtained fully justify the experiments, and the behaviour of the sections under traffic and under bad weather conditions is being very carefully watched and recorded. One interesting feature of this class of work is that the treated surface, if not satisfactory, can, months after, be loosened up and retempered by the addition of further road-oil or further dry pumice, as the case may require. The section of light bituminous-concrete pavement laid on the Christchurch-Dunedin Main Highway about two years ago is still in perfect condition. It now happens that the section is sandwiched between two long lengths of Portland-cement concrete pavement. In the Waimate County, in South Canterbury, on the Waimate - McNamara's Corner Highway, a length of gravel road was treated by what is known in America as the " oil-mix method." Heavy fuel oil was applied in two applications, each of approximately 0-5 gallon per square yard. The average thickness of the treated surface after compression by traffic was about If in., and the total cost was approximately Is. 2d. per square yard. The time which has elapsed since the construction is not sufficient to enable a definite pronouncement to be made as to the success or otherwise of this type of surfacing, but up to date the indications are favourable. During the past two years a number of proprietary bituminous emulsions have appeared on the New Zealand market. Many local authorities, in a number of cases with the assistance of the Board, have treated short sections of macadam and gravel road with these materials. The results obtained are being carefully watched by the representatives of the Main Highways Board in different districts. Examination of Foremen and Overseers employed on Road-construction. The fourth examination of foremen and overseers for the purpose of issuing certificates of competency was held on the 4th June, 1929. Fifty candidates sat for the examination, as compared with fifty-two last year and forty-eight the previous year. Nine candidates passed the full examination. One candidate completed the examination, having passed in one subject previously, and nine candidates obtained a partial pass.
