PUBLIC WORKS STATEMENT (BY THE RIGHT HON. J. G. COATES, MINISTER OF PUBLIC WORKS).

Mr. Speaker,— The Coalition of the two main parties of the House and the consequent changes in the personnel of the Cabinet have caused me to resume the office of Minister of Public Works at a time when my predecessor had already prepared his Statement and estimates for presentation to honourable members. Although the details of the Statement and estimates show the result of the yeax's work carried out under his direction, I propose to preface them with a few general remarks on the intentions of the Government in respect to public works. For a number of years I have felt that an unbalanced industrial condition existed in New Zealand, due to an unduly large proportion of the population deriving a livelihood from works the expenditure upon which was from Government loan funds. The country has been pursuing a policy of development from borrowed moneys for a period so long that men have looked upon public works as a permanent avenue of employment. Many of them engaged in these works in early manhood and have reared their families while in the employ of the State. They have regarded their positions as being permanent, and failed to recognize that the tenure of their work depended upon the continuance of a policy to construct works from capital-moneys. So long as the progress of the country justified the carrying -on of developmental works, and our industries, particularly the great primary industry, increased at a rate faster than that at which borrowed money was spent, the position was sound; but when uncontrollable causes, especially the fall of world prices of primary products, caused a suspension in the expansion of industry, the justification for developmental works became less apparent. Ido not mean to say that developmental works should then cease altogether. There should be a gradual tapering-off to enable those men displaced from one calling to have the opportunity of establishing themselves in other industries. The financial position in the country to-day calls upon the Government to provide as much work as it can to tide the country over the difficult period until industries are established on a new basis. For this reason it is still necessary that certain public works should be carried out. Honourable members have my assurance that it will be my endeavour while looking to the ultimate reduction in the expenditure of capital-moneys to see that such borrowed money as is available is spent to the best advantage on undertakings that promise to return the greatest value to the State. More particularly is it desirable that the public works undertaken in the future are of a character to enable more people than at present to earn their living at rural

occupations and in other spheres which will result in increased production. With the price per unit of our products greatly reduced, our efforts must be to increase the number of units for sale. One of the works which can be carried out and which fulfils the condition I have mentioned is the metalling of rural roads, and it is the Government's desire to change over as quickly as possible from formation work to metalling settlers' roads. Not only will this plan enable the farmer to make better use of the land of the Dominion, but it will, by improving the amenities in country districts, tend to check the movement of workers from the country to the cities. It is also hoped that work of the kind will encourage some people to take up again rural occupations. In addition to borrowed money being used to tide the country over the present difficult phase, there are the funds raised by special taxation under the Unemployment Act. Unfortunately, owing to the endeavour to keep men employed near their homes, and the fact that there is more unemployed labour in the towns than in the country, the works carried out through the medium of the unemployment funds have been mainly of an urban character. Although the works have been the best that local authorities have been able to arrange, they have not resulted in the production of wealth or in an increase in the volume of products for export. My endeavour in the future will be to divert labour available, and such funds as can be justifiably raised, together with a portion of the Unemployment Board's funds, to carrying out rural developments. Some of these rural works must continue to be what has commonly been understood in the past as public works. I have more particularly in mind the improvement of lands. Men now being displaced in work on railway construction will be given work as far as practicable in metalling roads in outlying districts, on new blocks of land, in forming and making new roads necessary, and in fencing and in preparing those blocks for settlement; also on undeveloped lands, construction, of irrigation schemes, reclamation of lowlying country and sand-covered country. In all probability greater national returns can be obtained by intensive work on successful farms than on any possible development of the poorer lands. Ido not mean from this that there should be any slackening-off in the endeavour to bring in virgin land or to restore deteriorated land, but unemployment and the country's financial position demand immediate consideration, and the quickest response will come from the application of labour intelligently directed on our best farming-land. As Parliament has adopted the report of the Railways Board and has discontinued work on all the railways which the Board recommended be suspended, the estimates so far as they affect those railways have been recast and make provision only for liabilities to date and the estimated cost of clearing up and securing the works and plant. Touching the subject of hydro-electric development, which is really a commercial undertaking, it will be necessary so long as the policy of the Government to control the bulk sources of supply is continued, to spend money on new developments as fast as the growth of load continues. In the past the growth has been remarkable, but with financial tightness a slackening in the rate must be looked for. Whatever the financial condition of the country, there must come a time when there are no new areas to reticulate, and the growth of load thereafter will depend upon the increase of population, together with the utilization of electrical energy in channels in which it is now not used. There is still a healthy increase in most districts in the demand for electrical energy. It will shortly be necessary, if this additional demand is to be met, to give consideration to developments or extensions of existing stations. Development in this direction as in all others, must, of course, depend on available finance. Even though it be found impossible for a time to borrow money abroad it will be necessary, to employ our labouring population and to prevent complete stagnation, to carry out a certain amount of work with the financial resources obtainable within New Zealand. I am satisfied when the issues are put to the test it will be found that the resources of New Zealand are greater than we have imagined. In conclusion, the country is to-day, so to speak, in "reverse gear." Publicworks activities may be said to be running in " top gear." A " change of gear " must now be made. The statement of the year's operations and comments on same by my predecessor now follow.

II

D.—l.

Statement by the Hon. W. B. Taverner. The fact that public-works expenditure is steadily increasing notwithstanding the fact that our national income has of recent years been decreasing, has caused me to carefully investigate all branches of the Department's activity, and the ability of suggested works to eventually bear at least a substantial portion of interest and sinking fund on the capital involved has been my first consideration. The developmental value of public works is a factor not readily assessable in terms of money, and it is necessary to take a longer view than that of the present or the immediate future. Public works are, in the main, purely construction works of a developmental nature, and so they should be regarded in endeavouring to arrive at a correct assessment of their economic value. In view of the uncertainty of the position, I have used every endeavour to keep the amount being expended on railway|construction within limits, and have refrained from placing on°order large quantities [of structural steel and other material which would be required should Parliament, after consideration of the| report of the Eailways Board which they are required to frender to the House under the provisions of section 18 of the Government [RailwaysjAmendment Act, 1931, decide to complete the various lines. This report, having now been submitted to Parliament, indicates the opinion of the Board in regard to railway-line construction. Ido not propose to oiler any comment thereon at this stage. For the information of the House, however, I desire to say that a cessation of expenditure on railway-lines construction would not mean that loan-money would not continue to be spent on the railway system. I would point out that the estimates now before the House provide for the sum of £1,020,000 under the Railways Improvement and Addition to Open Lines vote being made available direct to the Working Railways Department. It should also be borne in mind that, should Parliament decide to endorse the recommendations of the Railway Board and entirely cease construction, considerable expenditure would yet be involved in stopping the works, and this, at a rough estimate, I am advised would be £100,000. It cannot be gainsaid that with the low prices for our primary products, resulting in decreased revenue, it is quite impossible to continue developmental works, providing no direct return, with borrowed money at the rate which has obtained during past years, and the provision of work for the relief of those unfortunately unable to obtain employment except from the State relief works must in the future be financed to a much larger degree, if not entirely, from revenue funds and not from borrowed money. In the Public Works estimates now before the House it will be seen that reductions are proposed under most heads. It has been pointed out elsewhere that the provision of loan-money for this year's public-works operations has been very considerably reduced. The expenditure of a sum of over eight millions on public-works activities in times hke the present cannot be justified, unless the works are essential works of a reproductive nature ; but the position has been that, on account of the imperative necessity of aflordmg employment to large numbers of men, the suitability of certain works from the employment point of view has possibly outweighed their justification from a developmental or economic point of view. To expend large sums of borrowed money upon relief of unemployment, other than as a temporary expedient, is unsound and should not be continued, and assists in no small degree to increase the burden of our annual loan indebtedness. It is intended, therefore, to gradually dimmish the relief works hitherto carried on by my Department. The time has arrived when the Unemployment Board should have complete control of the relief of unemployment, and it is the duty of Parliament to render available to that Board a sum adequate to the needs of the situation, always having in mind the relation of the expenditure of revenue in this direction to other forms of expenditure. The amount spent by the Department under this head during[the last four years are as follows : 1928, £284,427 ; 1929, £665,715 ; 1930, £625,391 ; 1931, £1,032,102 ; 1932 (proposed), £700,000 ; and the weekly average numbers of men to whom employment has been given during the same period are 1,908, 3,016, 3,713, and 4,888.

III

D.—l.

It is essential that the Department should render the fullest possible assistance to the Board to carry out schemes that may be decided upon, and every effort will be made in this direction. All facilities available to my Department are at the disposal of the Board. Up to the present the local bodies in the centres of population have been largely depended upon to provide relief works. Such works" are becoming increasingly difficult to find, and indications are that whatever relief will in the future be provided will have to be somewhat further afield. The Public Works Department has the necessary organization and staff in the country districts to efficiently undertake and supervise such works, which would certainly be of a more useful character than many of the relief works which up to the present have been undertaken adjacent to the towns. The unemployment-relief works carried on by my Department were, in the early stages of the unemployment problem., the sole avenue of Government relief work ; but with the increase of unemployment and the creation of special machinery in the form of the Unemployment Board to deal with the question, the relief works of my Department are now only supplementary to the operations of the Board. In this connection it has lately become apparent that there now exists a position which gives to the small number of relief workers under my Department the monopoly of full-time employment, while the less fortunate majority are restricted to the intermittent relief available from the limited resources of the Unemployment Board. The construction of roads, particularly the widening and improving of existing roads, provides the simplest channel for the employment of unskilled labour, particularly with reference to the fact that it involves the purchase of very little material, thereby allowing the money to be utilized for wages as far as possible. Even although the metalling of roads may not fulfil the above requirements quite so completely as improvements of alignment and grade, nevertheless the decided advantages to settlement of metalled roads has prompted a decision to utilize relief funds in the providing of metalled surfaces to roads giving access to rural properties, and during the past few months quite a lot of work of this nature has been in hand. A continuation of the policy of the past, it may be pointed out, is contrary to the principles embodied .in the Unemployment Act, where it is definitely laid down that relief is to be financed from taxation. To the extent that the Public Works Department expends loan-money on relief works that principle has been violated. From every angle, therefore, from which the position can be viewed it is deemed desirable to diminish loan-expenditure under this head and to so arrange that any works carried out by my Department for the relief of unemployment should be at the request and on behalf of the Unemployment Board. HYDRO-ELECTKIC OPERATIONS. Hydro-electric development and operation has again been one of the most important functions of the Department. The year under review has been a most critical one, owing to special circumstances which developed during the preceding year, and which were discussed in my previous Statement. Following on the report received from the expert engineer brought from abroad by the Government to investigate the failure at Arapuni, remedial measures to recondition these headworks were commenced on the lines of his suggestions. The severe drought at Lake Coleridge continued well into the summer and a fuel generating plant was installed on that system as an emergency measure to safeguard the position for the immediate future. Despite the adverse effect these events have had on the operating results of the hydro-electric system, the account generally still shows quite a reasonable return on the capital operation. In the following table, giving a summary of the year's operation, the average capital cost includes the whole of the capital expenditure on any part of the system which is in operation or capable of earning money. At Arapuni, for example, the capital represented by the danl and headworks which, for the time being, are out of operation is included for the first quarter of the year during which the plant was in operation, but the capital represented by transmission-lines, substations, &c, is included, even though these assets are operating only to a partial extent owing to the limited amount of power available on the system.

The graph above indicates that despite the the general average has been well up to that of previous years. There are indications that the general period of depression is having some effect on the rates of increase in power-demand for bulk supply. On account of the totally different conditions under which we are operating in the AucklandWaikato area as compared with last year, it is not possible to make any very definite comparisons, but in the Mangahao-Waikaremoana system for the quarter ending June, 1931, there has been an increase of only 5 per cent, as compared with the same quarter of last year, whilst in the Lake Coleridge system there has been a decrease of 3 per cent, as compared with the same quarter of the previous year. Both these figures show very considerable reductions on the large increases which have been usual during the previous two or three years. Arapuni Hydro-electric Works. The report on this scheme submitted by Professor Hornell, which was laid before honourable members last year, was fully considered by the Government and a decision arrived at that work on the re-establishment of the development should proceed, so as to get the plant into operation at the earliest possible date. The Department was accordingly in December last authorized to proceed with the work as outlined in that report, and also to do some further work on stabilizing the section known as the " waterfall " which, in the opinion of the Government, was one of the most important parts. Work on all sections is now well in hand, and it is hoped to again have the plant in operation, for the winter of 1932. As this work is of considerable public importance, the attention of honourable members is directed to the detailed report of the Engineer-in-Chief, which will be found in another part of this Statement. I desire to say, however, at this stage, that lam very satisfied with the progress of the work and that the indications are that it will be completed well within the estimate made last year. By utilizing all existing auxiliary plants in the area, the Department has been able to supply practically the whole demand that has been made for power. The Auckland Power, Board, immediately following the breakdown at Arapuni, placed an order for an additional 15,000 kw. set for its King's Wharf Station, and now this is in operation the Board is in a position to supply power back to the Department for use by its other consumers should occasion demand.

Waīkaeemoana Power Scheme. No new developmental work was carried out at Waikaremoana during the past year, but the station was operated continuously in conjunction with the Mangahao Station. Surveys and investigations are still in progress, and it will be .necessary at no distant date to consider putting in hand work for the development of further power from Waikaremoana. Lake Coleridge System. As mentioned above, the severe drought in this area which commenced in the summer of 1930 continued right through until the end of that year. The result was that the level of the lake was drawn down to such an extent that supply authorities had to be asked to restrict their loading, so as to limit the drop in lake-level to such a point as would still enable the Department to take some advantage of the storage left to cover daily fluctuations in load. The Department was assisted to a very material extent by the co-operation of the authorities concerned, and it was possible to reduce the load over a period of about three months by approximately 2,000 kw. In addition, the Government made urgent inquiries for additional plant which could be installed to meet any prospective shortage this year, and which might also act as a general standby. As a result a Diesel generating-station was decided upon, and this has been established at Lyttelton. Four engines, each of 1,500 kw. capacity, were purchased in England, and the first of these went into operation at the end of June, and at the moment all four of them can be operated if necessary. The station has also been designed so that the three similar engines at present at Penrose (Auckland) can be removed and located in an extension to the station, and this will provide a total of 9,100 kw. available as standby. Fortunately the latter part of the past summer and the early winter has been unusually wet in this area, and the lake has so far recovered its level that it is now over 9 ft. higher than it was at the same time last year. This should ensure that it will be completely filled by the end of the year, and the position next summer, even without the operation of the standby plant, should be much more satisfactory. Waitaki Hydro-development. Work on this development has progressed at full speed throughout the year, approximately one thousand men having been continuously employed. Damage done to the temporary works during a heavy flood in February last, rendered necessary some modification to the original programme. It is not now proposed to close off the Otago half of the river this winter, as originally intended, but to leave this work for the following winter and to carry on meanwhile with the powerstation and the work on the Otago shore. After lengthy negotiations an agreement has been reached with the Dunedin City Corporation for the supply of power from the Waitaki - Lake Coleridge system. This will obviate the necessity for the City of Dunedin to further develop their own installation at Waipori, and will give the Waitaki system a valued customer. There is no question but that the interconnection of the two systems will add to the security and reliability of each of them, and be advantageous both to the Department and to Dunedin. Electric Supply Operating Accounts. Horahom-Arapuni. —As mentioned earlier, the Arapuni Station has been out of operation for the greater part of the year, and during this time, for the purpose of accounting, the headworks have been considered as being under construction.

The balance has been used in paying interest and depreciation charges. This does not provide the full statutory provision, but leaves a deficit of £35,694 on the year's operations. The reserve accounts established in connection with the scheme now show that £186,405 has been paid to Depreciation and £56,740 to Sinking Fund. The fourth generating unit, of 15,000 kw., the delivery of which was held back pending decision on the question of remedial measures, has since been delivered, and erection work is in hand, so that the machine should be available as soon as the headworks are again in commission. Waikaremoana-Mangahao. —These two stations have been delivering power into a common system of transmission and distribution throughout the year, and, despite a certain amount of dislocation following the Hawke's Bay earthquake, the financial position continues to show some improvement. £ Capital investment at end of year . . .. 3,498,840 Eevenue 283,017 Operating-expenses .. .. .. .. 59,476 Balance £223,541 The balance has been used in paying interest, and has, in addition, allowed a payment of £63,850 to the Depreciation Account, which now stands at £284,966. The Hawke's Bay earthquake was felt very severely over a good deal of the territory served by the system. No damage was done at either of the two powerstations, though a considerable amount of damage was done to chimneys and all loose material in the staff cottages at Waikaremoana. The Department's substation at Taradale (Napier) was, however, severely damaged, the main transformers being overturned, and portions of the building will also require fairly extensive repairs. An extensive slip between Napier and the power-station also carried away two of the main transmission-line towers and necessitated a deviation being built over a length of one mile and a half to clear the broken country. Despite the severity of this calamity, however, the Department was able to make power available again at Taradale within thirty-six hours of the occurrence of the earthquake. Though the load taken by the Hawke's Bay Power Board necessarily showed considerable reduction for some time, it has already risen again to figures in excess of what was taken before the disaster occurred. Lake Coleridge. —l have already mentioned the unfortunate restrictions that had to be imposed on account of the unprecedented drought in this area. This, of course, also had considerable influence in increasing operating-costs and decreasing revenue returns. Nevertheless, the year has been a siiccessful one. £ Capital investment at end of year .. .. 1,712,555 Eevenue .. .. 217,632 Operating-expenses .. . . .. . • 57,033 Balance .. .. .. £160,599 The balance has been used in payment of interest: £13,290 has been paid to the Depreciation Account/'£17,126 to Sinking Fund, and £52,957 to General Eeserve. Electric Supply Authorities Activities. The regulations governing electric supply and installations of all authorities are at present being revised by the officers of my Department, assisted by an Advisory Committee on which other interested parties are represented, and it is hoped that a new issue may be made available during the coming year. lEEIGATION. During the year a considerable amount of investigation and survey work has been carried out in connection with irrigation schemes in Central Otago. The data thus obtained is now being compiled, and early consideration will be given to the question of the desirability or otherwise of further extensions of the irrigable areas in that district. The totalfexpenditure which the Public Works Department has incurred on irrigation in Otago up to the end of March, 1931, amounts to

VII

IX—Li

£981,688. The total area at present irrigated under the eleven completed schemes is 42,672 acres, and the irrigators under these schemes number 408. It is interesting to note that the total land owned by farmers who irrigate the 42,672 acres under the Government schemes is approximately 250,000 acres, or six times the area irrigated. The rates charged for water range from ss. to 14s. per acre, the average being approximately 10s. per acre. The present average is 7s. per acre, due to the fact that the system of rating is based on a graduated scale varying from Is. per acre in the first year to the full rate in the fifth or sixth year. On account of the difficulties through which the farming community is at present passing as a result of the period of depression, difficulty is being experienced by my Department in collecting payment for water-supply. The amount of rates for last financial year, including the rates unpaid during former years, amounted to £18,787, and of this amount a sum of no less than £12,933 yet remains unpaid. From a departmental point of view the position regarding unpaid rates is unsatisfactory. It is evident, of course, that the low price-level is largely contributing towards this difficulty ; but, even so, it is considered that in many cases there is no justifiable excuse for non-payment, and it seems apparent that greater pressure must be brought to bear to obtain payments of arrears, some of which have been outstanding for a considerable period. While every effort has been made to collect these outstanding rates, it became apparent to me that, as other Government Departments were in a somewhat similar position regarding outstanding amounts due to existing conditions, whatever action was taken by my Department in regard to unpaid irrigation charges should be in conformity with the action taken by those other Departments, and that the Government's policy should be of a uniform nature. Arrangements have therefore been made for the Otago Land Board, which has been handling the question of rent unpaid by Crown tenants, to investigate each case of unpaid irrigation charges and report to me, after consideration of the irrigator's ability to pay, its recommendation as to whether payment should be enforced, rebated, or postponed. The following graphs indicate conclusively that the benefits resulting to this district from irrigation are considerable, and the indirect return to the Consolidated Fundjas a result of increased production would appear to fully justify the capital expenditure involved in the schemes.

In order to show that the increases indicated in the above graphs are not entirely due to the general increase that has taken place in live-stock throughout the Dominion, the following graphs, Nos. 3 and 4, have been prepared. No. 3 shows that the percentage of increase in dairy cows in the Vincent County exceeds the Dominion total and very greatly exceeds the increase in Otago and Southland. In fact, while the number of dairy cows for these two provinces has shown a decrease since 1924 of about 13 per cent., the number in Vincent County has increased about 7 per cent.

Although, graphs 3 and 4 are instructive in the way of showing that the counties afiected by irrigation have more than kept pace with the general growth of dairy and sheep farming in the Dominion, they do not fairly show the progress that has really taken place in these counties. It has to be remembered that over the lands which are suitable for irrigation in Otago Central the rainfall is extremely small, and that without some artificial means of watering these lands very little increase at all could have taken place in farm-produce. Therefore graphs 3 and 4 as well as graphs 1 and 2 are really indicative of the progress that has been made due entirely to the irrigation of the land. The above graph shows the increase in traffic from 1915 to 1930 for sheep, pigs, and cattle from the various railway-stations in the irrigated area. Taking the figure of 16s. per head as a fair value to allow for the production for a sheep per year, the increase in production due to irrigation for sheep only can be calculated at £104,000. Similarly, taking the annual value of the production from a dairy cow as £13 10s. and the increase in numbers of dairy cows due to irrigation as 1,200, the increase in the value of the products from this source can be calculated at £16,000. The total increase in production primarily due to irrigation from these two sources alone can therefore be set down at £120,000 per annum. Future Proposals. The amount proposed to be made available this year for the development of irrigation in Central Otago is £75,000. The possible future schemes that have been under review are the Omakau-Lauder-Matakanui, taking supply from the Upper Manuherikia River, which would irrigate between 14,000 and 15,000 acres at present owned by fifty-two individuals. In the absence of complete detailed surveys and plans, the estimated cost of this work is £267,000, and the annual charges would amount to £12,550. The next scheme under consideration is known as Becks-Clyde, also taking supply from the Upper Manuherikia. In this case there would be available for irrigation purposes 28,000 acres of land at a total estimated capital outlay of approximately £680,000. The third scheme in regard to which a certain amount of information is available is known as the Lake Hawea electric pumping scheme, which would irrigate about 14,000 acres of land. In regard to this area a tentative proposal was recently made to the Government that private enterprise would be prepared to undertake this work, and a reply has been given to the effect that the Government would give its answer to the request for a license when a definite proposition is submitted. The remaining schemes which have at one time or another been investigated are the Roaring Meg electrical pumping and the Ettrick or Teviot extension. In the first case about 8,000 acres could be irrigated, and under the Ettrick scheme a much smaller area. With regafd to the Maniototo Plain, the irrigable area is very large, probably amounting to 120,000 acres. No tentative estimates have yet been made in regard to this very large undertaking, but it is obvious that if its development were undertaken it would have to be of a progressive nature. The supply in this case would be drawn from the upper reaches of the Taieri River. The Maniototo Plain is held in large areas, and the number of present settlers who would be irrigators has not yet been established. Various surveys and the collection of data of an engineering nature have been in hand by my Department for some time past in connection with the possibilities of this area. The prospects of increased production from Otago Central are too well known to need any further elaboration in this Statement, and, as pointed out above, it is necessary that those engaged in promoting extensions of irrigation schemes should bear in mind that, judging from the experience of schemes at present operating, the indirect or national benefit accruing as the result of making water available to land hitherto unproductive entirely outweighs the direct" return provided by a water rate. , : ...-.

EXPENDITURE. The total net expenditure under all votes and accounts appearing on the public-works estimates for the financial year ended 31st March, 1931. was £8,388,529. Of this sum £4,810,659 was expended out of General Purposes Account, and the balance, £3,577,870, 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 last, follows in tabular form :—

The gross cash expenditure on works and services under the direct supervision or control of the Public Works Department itself was £8,098,301. This includes expenditure from the Public Works Fund, Consolidated Fund, Main Highways Account, Electric Supply Account, Railways Improvement Account, and various other accounts. The Department also collected in cash a total of £707,820 as revenue from electric-supply and irrigation undertakings. The total, therefore, of gross cash expenditure and revenue for the year was £8,806,121. This figure is exclusive of interest and loan charges, credits-in-aid for works of various kinds, and sundry relatively minor items of revenue, and gives some indication of the volume of work handled by the Department's staff.

RAILWAY-CONSTRUCTION. The net expenditure as shown on graph was £3,005,811, being £33,729 less than that of the previous year. The total length of all lines under construction over which goods and passenger traffic has been run during the year was 48 miles, and these services have been well maintained. 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 Rangiahua Section was closed down in January last. During the early part of the year three large slips were shifted and the line consolidated where the country was very unstable. Two bridges were erected, and the platelaying was proceeded with for a further distance of 1 mile 5 chains. Ballasting has practically been completed to the rail-head at 35 mile 45 chain peg. The ballast was obtained from the Okaihau Quarry, which delivered 26,274 cubic yards of crushed metal and 2,474 cubic yards of spalls for the period. Dargaville Branch Railway. —During the period three steam-shovels had been operating on this line, and the construction was proceeding rapidly when works were closed in December last. The railway has practically been completed to 1.6 miles 23 chains peg with the exception of two small sections where subsidences have occurred, making it necessary to construct temporary deviations in the meantime. Three permanent bridges were erected, totalling 395 ft. in length. Goods traffic was commenced in December, 1929, and a passenger service was inaugurated between Kirikopuni and Tangowahine, a distance of 10 miles 10 chains, in September, 1930. On the works closing down some of the men were transferred to Arapuni hydro-electric works and others were absorbed in various road works in the vicinity. There are still 1 mile 50 chains of light formation, 3 miles 70 chains of platelaying, 7 miles of ballasting, three bridges, and the necessary station buildings to complete this line. Gisborne—Napier Railway. —The construction of this railway between Waikokopu and Gisborne was discontinued in January last. Up to this date formation was in hand on the Gisborne Section (14| miles), Wharerata Section (10 miles), and Kopuawhara Section (11 miles). Co-operative contracts were in hand over the greater portion of these sections. On closing down, some of the workmen were transferred to Galatea roadworks and others to Arapuni. The Putorino Section, 26 miles 59 chains in length, was completed and handed over to the Railway Department on the 6th October, 1930, and from that date maintenance and control was carried out by that Department. Work on the Wairoa Section has progressed steadily, and it is expected that the line will be completed to Wairoa about September, 1932. The following bridges were completed during the year : Waihua River Bridge ; Ohinepaka Stream Bridge at 64 miles 7 chains ; Ohinepaka Stream Bridge at 64 miles 47 chains ; Hurumua Stream Bridge. The following major works are in hand : — Kotemaori Tunnel: This work has suffered by various stoppages due to labour disputes, but it is confidently expected that it will be completed in six months' time. The bottom heading was pierced in September last, and 11|- chains on the south side and 14| chains on the north side have been enlarged and concrete-lined. There is still 7|- chains of enlarging and lining to complete the tunnel. Mohaka Viaduct: Very good progress has been made with the foundations, and they will be completed in about three months' time. Maungaturanga Viaduct: The steelwork is nearing completion, and this viaduct will soon be ready for traffic. Station buildings have yet to be erected; 10 miles of platelaying and 15 miles of ballasting have yet to be completed.

Stratford Main Trunk 'Railway. —On the eastern end the passenger and goods service has been well maintained between Okahukura and Ohura, and early this year a goods service was started to Tokirima, thus extending the means of transport a further distance of 8 miles. The total distance over which this service is now run is 27 miles from the North Island Main Trunk Railway, and settlers are thus receiving most of the benefits of a completed railway in the transport of stock and manures, &c, particularly as through rates are given to and from any stations on the opened railways. On the western end the tri-weekly goods and passenger service has been maintained between Tahora and Tangarakau, a distance of 3j miles. This has enabled the coal from the Egmont Collieries mine at Tangarakau to be marketed. The formation has steadily progressed during the year. On the Tokirima Section the earthwork formation is practically complete. The six tunnels, aggregating \\ miles in length, have been finished. The bulk of the work is now being concentrated on the Heao Section (3 miles 50 chains in length). Three bridges over the Heao Stream are being erected, and the remaining two tunnels are in hand. No. 1 Tunnel (8 chains long) has been pierced, and is now being enlarged and concrete-lined. The Mangatete Tunnel (55 chains long) is manned at both ends, 20 chains of bottom heading being driven on the east end and 22 chains on the west end. Approximately 8 chains of enlargement and concrete-lining has been completed at the west end. The Tangarakau River Bridge, consisting of 25 ft., 30 ft., 60 ft., 80 ft., and 60 ft. girder spans, has been completed. The work on this railway is nearing completion, and the line should be ready for handing over to the Railway Department about July, 1932. Wellington - Taiva Flat Deviation. —During the year work has been continued on the sea-wall, which has been extended a further 22 chains, and at Kaiwarra the embankment has been extended a distance of 16 chains. The No. 1 Tunnel has been enlarged to full size and concreted throughout its entire length, a distance of 61-58 chains. The No. 2 Tunnel has progressed satisfactorily. The heading from the north end has been extended 54 chains and from the south end 54J chains. There is still approximately 21 J chains of heading to complete. The tunnel has been enlarged and concreted for a further 38 chains during the period. Tunnel-work was interrupted for a period of nine weeks on account of the disinclination of the tunnel-workers to accept the modified prices fixed by the Government. This has now been overcome. The formation has been completed from 6 miles 14 chains to 8 miles 26 chains, except for a small gap at 6 mile 72 chain peg. Concrete culverts have been placed totalling 488 lineal feet, and five girder bridges have been erected. Midland Railway. —The construction of this railway was closed down in January last, and up to this date formation had practically been completed to 82-mile peg. Everything was in readiness for platelaying and ballasting to commence, and this work could have been proceeded with without interruption up to 82-mile peg, a distance of 14 miles. Westport-Inangahua Railway. —The formation is progressing satisfactorily. The Cascade Section, 3 miles 8 chains in length, is practically complete, and coal traffic from Cascade Mines has been carried over it. On the Hawk's Crag Section, 9 miles long, formation has been completed for a distance of 7 J miles. A start has been made with driving the bottom heading for the tunnel at 13 miles 41 chains. Owing to an unfortunate disaster, involving the death of three men, and owing to disputes regarding tunnel prices, operations were suspended. The parties have now been reorganized and a fresh start is being made. The erection of the Cascade Creek Bridge at 9-mile peg, consisting of five 80 ft. and one 40 ft. spans, is in hand. This bridge is on a 7|-chain curve, and massive concrete piers have been placed." It is anticipated that this bridge will be completed in about twelve months' time. A suspension bridge 530 ft. long over the Buller River has been erected to enable workmen to reach their work on the opposite side of the river from the camps.

XV

D.—l.

On the Orikaka Section formation has proceeded satisfactorily, and the whole section, 9| miles in length, is now fully manned, 4j miles being completed. Some of the cuttings on this section are exceptionally heavy, as the country is precipitous. A suspension bridge across the Buller Eiver, 540 ft. long, is being erected at the 19-mile peg to facilitate access to the men camped there. South Island Main Trunk Railway. —At the north end of this railway formation work has progressed satisfactorily on the Clarence Section, 20 miles in length. Foundations have been completed for bridges over Kekerangu, Deadman's, Woodbank, and Washdyke Streams, and the permanent bridges will be completed as soon as the girders and steel come to hand. At the south end formation is in hand on the Conway and Oaro Sections. The Conway Section is being worked by heavy machinery, six steam-shovels, two drag-lines, and eight locomotives being utilized. A very heavy cutting, 46 chains long, is in hand. This is to take the place of a tunnel which was originally proposed. At Parnassus an up-to-date workshop and plant-depot has been established ; sixty-one married men's quarters and 134 single men's huts and two staff cottages have been built. At Wharanui an office, store, smithy, carpenters' shop, garage, fitting-shop, recreation-hall have been erected, and at Camp No. 8 twenty-nine single men's huts and twelve married men's cottages. EAILWAYS. Additions to Open Lines. The net expenditure out of the Public Works Fund for the year ended 31st March, 1931, amounted to £526,514 11s. 3d., and was charged to capital. This sum represents the provision of new rolling-stock, grade-easements between Crichton and Lovell's Flat, additional dwellings, improvements and extensions to operating buildings and plant, workshop equipment, rearrangement of station-yards, and other facilities. Eailways Improvement Authorization Act, 1914. The expenditure under the Railways Improvement Authorization Act 1914 Account amounted to £1,018,615, including £45,928 proportion of cost of raising loan. The works carried out during the year included the completion of new station and yard at Auckland, new goods-shed at Wellington and reclamation for station-yard, Papatoetoe-Papakura duplication, reconstruction and strengthening of bridges, completion of Ravensbourne-Burke's Deviation, telegraph and telephone lines, safety appliances, and train-control; and in addition to these works, which were executed under the control of the staff of the Railway Department, the Public Works Department has proceeded with the Wellington - Tawa Flat Deviation described above. RIVER-IMPROVEMENTS AND LAND-PROTECTION WORKS. Waihou and OMnemuri Rivers. —The work carried out during the year comprised the raising of the stop-bank on both banks of the Upper Waihou River for a distance of 4 miles. Some of the drains leading into the Ohinemuri River have been deepened. The Tirohia-Rotokohu drain has been cleaned out for a total length of|3j miles, and Te Tawa drain for 1 mile. Taieri River. —The contour channel has been improved over a distance of 4 miles, and the whole work to be carried out by my Department on the Taieri Plain is complete and has been handed over to the Taieri River Trust for future maintenance. HARBOURS. In order to improve the entrance at Westport, an extension of the trainingwall was put in hand during the year, and dredging was steadily proceeded with. The funds for this work are provided out of the general revenue for the harbour, which in itself is largely dependent on the output of coal. Unfortunately, towards the end of the period this coal-output dropped very considerably, and in the interests

XVI

-D.—l-

of harbour finance it has been necessary to temporarily stop work on the extension. Dredging has, however, been proceeded with whenever possible, and the regular services have been well maintained. The position, of Karamea is, I regret to say, very unsatisfactory. The aftermath of the severe earthquake experienced in 1929 is still apparent, and is, I am afraid, likely to be so for many years. Large quantities of shattered material from the back country have been deposited in the river, which is rising and generally making navigation difficult, and increasing the flood menace over a considerable area of the district. The construction of the main training-wall has been proceeded with, a temporary wharf in a more suitable position is being erected, and endeavours are being made to so train the river as to improve the channel and make the best of the position as it exists. The contract for the construction of a breakwater at Waikokopu has been proceeded with, and although work was held up for some little time it is anticipated that it should be finally completed within the next few months. The improvement in loading-conditions at the wharf is becoming increasingly apparent as the work goes on. In addition to these main harbour-works, a considerable number of wharves and small harbour-improvements have been carried out in various parts of the Dominion with funds provided either in whole or part by the Government. LIGHTHOUSES. The policy of gradually improving and extending the various aids to navigation around the coast of New Zealand has been steadily proceeded with. Arrangements have been made to provide a new flashing light at East Head, near Le Bon's Bay, on Akaroa Peninsula, and it is anticipated that this work will be completed by Christmas-time. At Baring Head, the necessary land has been acquired and provision made for the transfer of the existing lighthouse at Pencarrow to this locality. When the transfer has been effected an up-to-date flashing light will be provided in place of the old fixed light now in operation, and the necessary housing for fog-signal keepers, and possibly a radio direction-finder, will be provided. A contract has been let for the construction of the access road and bridge. A new automatic flashing apparatus has been ordered for Godley Head Lighthouse, which will supplant the fixed light at present in use. Whenever possible, these old fixed lights are being converted to flashing operation, since the growth of population adjacent to many of these lights and. the more general use of electric lights renders it sometimes difficult for a shipmaster to distinguish between a lighthouse and what may be purely a domestic installation or even a motor-car. A new crane is being provided for the Brothers Lighthouse, and the station generally overhauled. At Kahurangi a new lens has been installed to take the place of the old lens, which was seriously damaged by the earthquake of the 17th June, 1929, and the tower itself has been repaired. A new and powerful diaphone fog-signal has been installed at Taiaroa Heads. It has been housed in a reinforced-concrete building, and is a thoroughly up-to-date and efficient installation. A radio telephone has been established at Portland Island, and general maintenance and repair work has been carried out at the various stations. IRRIGATION AND WATER-SUPPLY. During the year the existing schemes were maintained in good order. All lands requiring water have been served, and the season has been fairly successful, as the water-supply has been good, and the distribution of water has been subject to very little interruption. The schemes in operation on a trading basis are Ardgour, Bengerburn, Earnscleugh, Galloway, Hawkdun, Ida Valley, Last Chance, Manuherikia, Tarras, and Teviot.

The total area irrigated under all Government schemes was 42,672 acres, as against 41,895 acres last year, the number of irrigators being 408. The Poolburn Dam has been completed and has commenced storing water for next season's supply, and thus will supplement the Manorburn Dam supply for the Ida Valley Scheme and obviate the necessity for pumping from the Manuherikia River. The following graph shows the growth of irrigation under Government schemes for the last ten years.

ROAD-CONSTRUCTION. During the past financial year construction and improvement of roads throughout the Dominion were actively prosecuted, and many settlers who previously had little or no access to their properties have had their position in this respect considerably improved. The opening-up of new lands for settlement has also been responsible for increased roading activity, and several large areas are now being opened up. A total sum of £2,233,428 has been expended on the construction of roads and main highways, as against £2,158,056 for the preceding year. Roads other than main highways accounted for £1,475,522 of this sum, and main highways £757,906, compared with £1,060,908 and £1,097,148 for 1929-30. The actual increase in expenditure on roads other than main highways during the year is, therefore, £414,614, the increase being principally due to the necessity of providing work for the unemployed. As a result of the duration of the present depression and the need for providing relief for unemployed, roads throughout the Dominion which under normal conditions would be looked upon as of sufficiently high standard to meet present-day requirements have been further improved in width, grade, and alignment. Many roads have been, trimmed up in preparation for metalling, and in some instances in isolated districts, owing to special circumstances, metalling has actually been done by the Government. It is essential, however, that the hitherto-followed principle, in accordance with which local bodies finance a portion of the cost of metalling, should continue to be followed, and only those localities which warrant exceptional treatment will receive special Government assistance.

D.—l.

On the 3rd February, 1931, the Dominion was again visited by a disastrous earthquake, which played havoc with many roads and bridges in the Hawke's Bay, Wairoa, Dannevirke, and surrounding districts. Such widespread destruction as resulted is almost unprecedented in the history of New Zealand roads, and the reconstruction in the damaged area has placed, and is placing, a heavy burden upon the areas affected in particular, and upon the Dominion in general. Government assistance towards the cost of reconstruction of roads other than main highways has received consideration in. connection with the estimates submitted to the House. The restoration of the main highways has been vigorously carried out. What has already been done in the matter of reconstruction has been done well, and the gratitude of the public has been expressed through the press on many occasions. With regard to maintenance, it has not been possible to assist local bodies to the same extent as in the past. It must be recognized that the present financial position has had a distinct bearing upon this work, the general policy being to expend the funds available on major works suitable for unemployment-relief, thus assisting local bodies in their construction programmes and allowing local-body funds to be utilized in the maintenance of completed works.

PUBLIC BUILDINGS.

General Departmental Buildings. The balance of purchase-money for the new offices of the High Commissioner for New Zealand in London (£77,500) was paid during the year. At Auckland the lift in the Departmental Buildings was completed. In Christchurch new offices were erected on the top of the Government Buildings for accommodating the officers of the Scientific and Industrial Research Department. . . ; , At Dunedin a shed and store for housing plant and equipment was erected.

At Greymouth the explosives magazine was extended. At Nelson additions were made to the office of the Public Works Department, New offices were erected for the Land and Deeds Department at New Plymouth : and at Wellington additional lavatory accommodation was erected for the Government Printing Office, and a new central heating system is being installed. New offices for the Meteorological Department were erected in Kelburn. The total net expenditure under this vote was £100,927. Courthouses. The new Courthouses at Upper Hutt, Papakura, Maungaturoto, and Patea, which were practically finished at the end of the previous financial year, were completed and officially opened early in the year. A Courthouse at Hamilton was erected during the year and is now in use. The grounds have still to be laid out. Additions were also made to the Courthouse at Rotorua, and will provide for requirements for many years to come. The net expenditure under the vote was £19,572. Prison Buildings and Works. The expenditure on prison buildings and works was further reduced during the year, the total net expenditure being £2,504. Extensions of buildings at Invercargill were not proceeded with on account of the need for economy, and the proposed purchase of additional farming-lands at Invercargill was deferred. Accommodation has been taxed at almost all institutions, but apart from the establishment of a new camp at Hautu, it has not been considered necessary, up to the present, to undertake further permanent extensions on a major scale to prison accommodation. _ A summary is given hereunder of the classes of work on which last year's capital expenditure was made ; the previous year's figures also being quoted :— 1930-31. 1929-30. £ £ Erection and extension of buildings .. .. .. 535 1 79] Water-supply and sanitary drainage .. 217 612 Officers' cottages and quarters .. .. . . 389 2 460 Completion of access road (Wellington) .. .. 390 ' 747 Farm buildings . . .. .. ~ 315 gg^ Estuary-reclamation (Invercargill) 534 ] 399 Quarry and laundry plant .. .. .. 124 '302 £2,504 " £8,205 Police-stations. The expenditure on police-stations for the year amounted to £8,360 out of an allocation of £10,000. New police-stations to replace buildings which had become beyond repair were erected at Cromwell, Culverden, Milton, and Palmerston South. A contract was let for the building of a police-station at Te Araroa, and the work is now in hand. Post and Telegraph Buildings. Satisfactory progress continues to be made in the execution of the Post and Telegraph Department's buildings programme. New buildings were erected at Kurow, Mount Albert (Auckland), Napier, and Te Anga. Garages were built at Albany, Blenheim (also store, &c), Ohura, Rawene, Tikitiki, and Walton. Residences for Postmasters were erected at Hinds and Kurow. A building was erected at Mount Crawford (Wellington) for the accommodation of the New Zealand receiving-station of the trans-Tasman radio-telephone service.

Increased or improved accommodation for departmental purposes lias been provided at the following places : Christchurcli, Gore, Greymouth, Hokitika, Huntly (garage), Kaikohe, Kaitaia, Nelson, Newton (Auckland), Papatoetoe, Wairoa (garage), Wellington (workshops), Whangarei. The following works are in progress : Courtenay Place (Wellington East) — new post-office building; High Street, Christchurch—new post-office building ; Lower Hutt —automatic telephone exchange ; Masterton—additions and alterations ; Palmerston (Otago) —new post-office building ; Buatoria—new post-office and residence ; Upper Symond Street (Auckland) —new post-office building ; Urenui— new post-office building ; Waitara —new post-office building ; Westport —new chief post-office building. The foundations for the new chief post-office building at Dunedin have been completed. Plans and specifications for the erection of the building have been prepared, and tenders have been called, closing in January next. Plans and specifications have also been prepared for the new post-office building at Taumarunui, and tenders will be called shortly. The earthquake of the 3rd February, 1931, caused extensive damage to postoffice buildings in the Hawke's Bay District. The new chief post-office at Napier, which was completed and opened for business on the 28th July, 1930, withstood the shock, but was subsequently gutted by the fire which followed. The post-office at Port Ahuriri was badly damaged by the shake, and afterwards burned. At Hastings the clock-tower collapsed, and the old portion of the post-office building, which carried the tower, had to be demolished. The Wairoa Post-office was badly damaged, and the clock-tower collapsed. There was quite a number of other smaller post-offices which were damaged and which are being repaired. The net capital expenditure for the year amounted to £138,670. Mental Hospitals. The net capital expenditure for the year on mental hospitals amounted to £134.140. The following is a summary showing the position of the various institutions at the end of the year :— Avondale : A new two-story residence in wood has been erected for the Medical Superintendent; an additional lavatory block built for Ward M 9 ; and a new hot-water service has been installed at the Wolfe Home. Puhitahi: Villas Nos. 1 and 2 were erected in brick and concrete at a cost of £25,000. These buildings will accommodate 100 male patients. Tokanui: The Nurses' Home has been completed and handed over to the Mental Hospitals Department. A water-supply and fire service have been installed and the roads formed and metalled. A new transformer substation has been built and a standby generating plant has been installed. Porirua : A surgery has been provided for "A " Ward, female division, the electrical change-over to the 230 voltage was completed in several buildings and residences ; the reservoir was completed, the dam-face being concreted to full height. Several alterations were made to various buildings and renovations carried out as required during the year. Nelson and Stoke : Three villas commenced the previous year were completed, furnished, and occupied. The equipment for the new bakery was installed ; the Imhofi'e septic tank was completed, and all drainage connected thereto. The new reservoir for water-supply for Stoke is nearing completion. Contour plans of York property have been prepared. Sunnyside : A new villa, in wood, was erected, and will accommodate fifty-four male patients. Templeton : A fire service was installed for Villas Nos. 2 and 3 and extensive drainage-work carried out at Villas Nos. 1 and 2. Hokitika : A large villa, in wood, to accommodate forty-eight female patients, was completed and furnished during the year. A pumping plant was fitted up and laundry machinery installed. New farm buildings in wood and iron on concrete foundations were erected. Seaclifi : All necessary machinery and appliances were installed in the new laundry and kitchen block. The old kitchen block was altered and rearranged; new service roads and paths were formed, and additional lavatories provided.

D._ 1.

Waitati: A new villa for female patients was completed and furnished, and a new access road was formed. Health and Hospital Institutions. The chief works under this heading were the completion of additions to the Nurses' Home, erection of the porters' lodge, and a new laundry and fuel-shed at Otaki Sanatorium. Additions have also been made to St. Helens Hospitals at Gisborne and Wellington, and a new Nurses' Home has been completed at Invercargill. An additional grant was made to the Nelson Hospital Board for repairs to Nelson Hospital, damaged by the earthquake of 1929. Provision is being made this year for the erection of a building for the Raukawa Children's Health Camp, the site for which has been generously donated to the Government by Mr. Byron Brown. When completed it will provide a health camp for selected children. The net capital expenditure under this vote amounted to £17,338 for the year. Agricultural Buildings. The amount expended last year on capital works was £1,509. Additions to the Wallaceville Laboratory were completed, and an observation shed in brick has been erected. Education. The sum of £500,000 was estimated to cover the cost of the erection of school buildings, additions, sites, and teachers' residences during the year under review, the aetual expenditure being £501,344. Of this amount £203,292 was spent on primary schools, the larger works being additional accommodation at Brooklyn, Wellington ; Southbridge, Canterbury ; and new schools at Russell Street, Palmerston North ; Picton ; Eketahuna ; and Miramar Central, Wellington. Additions have been made to the Technical Schools at Auckland, Hamilton, Hawera, Wellington, and Invercargill; also to the Hastings High School, Rongotai Boys' College, and Wellington East Girls' College. Several large works are in progress at primary and secondary schools, and hostel accommodation is being provided at the Wanganui Technical School, Nelson Boys' College, and New Plymouth Boys' High School. The main building for the Massey Agricultural College is nearing completion. The recent earthquake in Hawke's Bay damaged a large number of the schools in the district, some of which have had to be demolished and are being replaced as rapidly as possible. The Education Purposes Loans Act, 1919, has been repealed by the 1931 Finance Act (No. 2), which also abolished the Education Loans Account. Amounts required for the erection of school buildings will now be paid out of the Public Works Fund as appropriated by Parliament for the purpose.

TOURIST AND HEALTH RESORTS. The net capital expenditure for the year was £60,288, as against £20,547 for the previous year. The principal works undertaken were in Rotorua. The Ward (formerly Pavilion) Bath building was reconstructed, and extensive additions were made to the electrical plant, the transmission-lines were extended, and reconstruction of the Blue Baths is now in hand. Improvements have been made to the reserves and the formation of a nine-hole golf-course has been completed. Additions to Glade House, Te Anau, have been erected, and hot-water service and drying-rooms are in course of erection at Quintin Huts, in the same locality. TELEGRAPH EXTENSION. The expenditure for the financial year in extending and improving the telephone, telegraph, and wireless facilities throughout the Dominion amounted to £419,756, as against £594,383 for the year ended the 31st March, 1930. Owing to the limitation of funds, it has not been possible to carry out such a large amount of work in extending telegraph and telephone systems as has been the case in previous years. Although the greatest possible use has been made of the amount available, the reduced extent of developmental work will, no doubt, be felt when the Dominion returns to normal and the demand for communication service is restored. A summary of the more important works upon which capital expenditure was incurred during the year is as follows : — The installation of a considerable amount of carrier-current equipment, the erection of new metallic circuits between Katikati and Waihi, Ngatea and Waitakaruru, Tauranga and Matamata (main toll route to east coast), Whakatane and Te Teko, and Te Kuiti and Te Anga ; the laying of submarine telephone-cable across Auckland Harbour and in the Marlborough Sounds ; the opening of new exchanges at Colville, Te Anga, and Waiotira ; the conversion to automatic working _of the Birkenhead Exchange area ; the installation in ten automatic exchanges and nineteen magneto exchanges of additional switching equipment; the establishing of sixtysix new public call offices (coin-in-the-slot telephones) ; the laying of 25 miles of underground cable-ducts ; the laying or erecting of 102 miles of lead-covered cable containing 1,896 miles of wire for subscribers' circuits ; the erection of 837 miles of pole-line and 6,781 miles of open aerial wire for telephone-exchange subscribers' circuits ; and the connection of 12,779 new subscribers' stations. The development of long-distance telephone communication within the Dominion, which has been a feature of the Government's policy in recent years, was advanced a further stage during the year by the opening for commercial traffic of the undermentioned additional carrier-current telephone toll systems : AucklandWhangarei —One single-channel system ; Auckland-Tauranga —One single-channel system ; Auckland-Napier —One single-channel system ; Napier-Gisborne —Two single-channel systems ; Napier-Palmerston North —One additional single-channel system ; New Plymouth-Wanganui —One single channel system ; WellingtonNapier —One single-channel system ; Wellington-Palmerston North —One additional single-channel system ; Wellington-New Plymouth —One single-channel system ; Wellington-Blenheim —One single-channel system ; Nelson-Blenheim —One singlechannel system ;• Seddon-Christchurch —One additional single-channel system ; Christchurch-Greymouth—One single-channel system ; Dunedin-Invercargill —One single-channel system. The installation of the additional carrier-current systems, besides effecting a substantial improvement in the speech efficiency, stability, and reliability of the network of long-distance telephone-lines throughout the Dominion, has improved the service generally by relieving the congestion of traffic between certain of the larger centres, thus appreciably reducing the delays on long-distance toll communications. The facilities now provided enable practically all the important centres

XXIII

p.—l.

to obtain reliable telephonic communication at all hours. The efficiency of the network of long-distance telephone communication in the South Island was further enhanced by the installation at Timaru of voice-frequency amplifiers. By means of this additional equipment, two high-grade telephone circuits have been made available between Ch.ristch.urch and Wellington, which, together with the additional carrier equipment, has resulted in a marked improvement in the volume, clarity, and reliability of the long-distance conversations over the various circuits with which the equipment is connected. A progressive improvement of the toll and telegraph wire systems has been aimed at throughout the year, and in those cases in which existing facilities could not be sufficiently augmented or improved capital works were undertaken with a view to erecting new circuits. The development of the local telephone-exchange systems throughout the Dominion has not been so great as in some other years. The number of new connections installed was 12,779, which is nearly as many as were installed during the previous year, but, as the number of relinquishments "of service was greater, the net increase in subscribers has fallen off to some extent. In view of the prejudical effects likely to be felt from the general depression now existing, the developmental work in connection with local exchange systems has been curtailed to some extent. At Wellington Radio a 165-ft. steel lattice mast has been erected. The higher mast and aerials have considerably improved the range of the medium-wave transmitters. A directional transmitting' array of the horizontal doublet type, with reflector of similar design, has been erected for the New Zealand-Australian radiotelephone service, which was obtained by the addition of a 5 kw. modulating-unit to the existing 3 kw. short-wave continuous-wave transmitter. A second array has been provided for the Pacific islands radio-telegraph service, with a considerable improvement in reliability. The change of voltage in the Wellington City powersupply system necessitated the complete replacement of the electrical wiring and the _ substitution of all direct-current motors by alternating-current type. To minimize the risk of an entire interruption to the power-supply, provision has been made for the supply to be obtained over alternative routes and for emergency service to be given from a, storage-battery source. The earthquake and fire in Hawke's Bay on the 3rd February, 1931, were responsible for a considerable amount of damage to telephone and telegraph, plant that was originally provided, out of Telegraph Extension vote. Temporary arrangements were made to carry on the communication services, but the whole of the equipment destroyed will ultimately require to be replaced. WORKS FOR DEFENCE DEPARTMENT. The net capital expenditure for the year under " Contingent Defence " was £13,812, as against £46,766 for the previous year. The restricted vote has meant that the expenditure and work carried out has been reduced to a minimum, and absolute immediate essentials only gone on with. The mobilization bases and training-camps at Waikato, Trentham, and Burnham have been maintained in good order. Various improvements to fortifications, drill-halls, and miscellaneous buildings throughout New Zealand have been carried out, and the buildings maintained. Owing to the Mount Cook site being required for the War Museum and Art Gallery, the Ordnance Workshops have been removed to Trentham. Central Command Headquarter buildings were burnt down, but in the interests of economy it was determined not to rebuild, but to transfer these Headquarters to Wellington. The Gisborne Drill-hall was totally destroyed by fire, but, owing to the Defence Department's programme of training being in abeyance and the necessity to economize, no action is being taken to rebuild until such time as the requirements of the district have been determined.

The development of the New Zealand Air Force Base at Hobsonville has proceeded satisfactorily, and the following works have been completed : Seaplane hangar block, comprising plumbers' and blacksmith shop, engineers' repair shop, aircraft-repair shop, marine store-room, Dope-room (less heating); also the married quarters, oil-store, fire-alarm system, No. 3 hangar, general store (ground floor only), fuelling-station, garage, and the sealing of the roads. Though the workshops have been completed, there has been no money available for machinery and fittings and tools. The Wigram Aerodrome has been maintained in fair order. PLANT AND MECHANICAL APPARATUS. The stoppage of four major railway-construction works in December last released a quantity of construction plant, at least half of which has now been transferred for use on other railway and hydro-electric construction jobs, which were previously short-supplied, and the remainder, which comprises the older and more worn items, is being, wherever expedient, put in good repair for transfer later to wherever required. Arapuni Hydro-electric construction works absorbed some of the available plant, as also did Waitaki hydro-electric works and the South Island Main Trunk Railway, but a certain amount of new plant also was required to carry out special work at Arapuni. Bridge-construction jobs in hand throughout New Zealand during the year necessitated the supply of a considerable quantity of plant. Machinery for the purpose of crushing stone in large quantities for road works in the North was installed at Motutara Island Quarry, and this necessitated several transfers of existing plant and a few new purchases. A good deal of old plant that has become too expensive to maintain, as compared with new plant, and certain obsolete plant has been disposed of by sale after calling for public tenders, this being the policy of the Department in all such cases. New plant items were purchased by public tender, to, in some cases, serve as replacements for discarded machinery _ The major items purchased during the year include one complete set of airlock equipment, two electric hoists, three steam boilers, nine motor-cars, twenty-five motor-lorries, four compressors, two conveyers, one overhead electric crane, six oil-engines, one mechanical excavator, five fans, two oil-burning rivet-forges, three motor graders, one mechanical loader, five electric-battery locomotives, four motor generator sets, two petrol-locomotives, one steam-locomotive, one petrol lightingset ; thirty-one machine tools, two drill-sharpeners, six concrete-mixers, four electric motors, twenty-three pumping units, five air-receivers, two road-drags, one sandblast plant, five tractors, one motor-velocipede, four welding plants, two oil winches, one electric winch, four steam winches and boilers. Inspecting of motor-omnibuses is carried out for the Transport Department, and work of a mechanical nature is carried out for other Government Departments and for the Cook Islands and Samoan Administration, as well as for local bodies throughout New Zealand. HAWKE'S BAY EARTHQUAKE.—OPERATIONS IN CONNECTION WITH RESTORATION OF DAMAGE. Early on the morning following the Hawke's Bay earthquake of the 3rd February last the Department's officers commenced emergency operations in connection with the erection of cookhouses and other emergency accommodation for the use of the various organizations set up to deal with "the earthquake situation. Cookhouses were erected at Nelson Park and six other suitable locations. The buildings housing the Napier Borough pumping-station and power-station were shored up and made safe for operation. The Hawke's Bay steam laundry was made safe for the handling of the hospital and other laundry-work. Parties of workmen were organized to temporarily cover the roofs of houses where chimneys had crashed through in the Napier Borough and adjoining districts, extending as far as Taradale and Clive,

XXV

D.-l.

At Nelson Park three large mess-rooms, staff mess-rooms, tot-water service. and sanitary accommodation were provided, and sanitary accommodation was also provided at Clive Square. On the 3rd March instructions were received regarding the effecting of minimum repairs necessary to make private dwellings habitable, to the extent of reconditioning eno chimney, permanently repairing the roof, and putting drains and sanitary fittings in good order. Owing to the absence of householders, the greatest difficulty was found in properly organizing this service. However, under the circumstances, good progress was made. It soon became apparent the work involved in reconstructing the drains at private houses was so extensive that operations were discontinued, and this work was left to be dealt with under the £100-loan scheme. The work done in the way of restoration of private dwellings is summarized as follows :— In the Napier Borough chimneys have been erected in 954 houses where roofs have also been permanently repaired and sanitary fittings put in order. In the Hawke's Bay County chimneys have been repaired, water-supply restored, and minor repairs effected in 367 houses, the operations extending to Taradale, Puketapu, Greenmeadows, Meeanee, Clive, Haumoana, Tukituki, Pakowhai, and Mangateretere districts. The greatest number of men employed at any one time in the work of chimney re-erection was 200. A good deal of difficulty was experienced in obtaining suitable labour, as the local reputable bricklaying contractors were employed on private work. It was found possible to let the plumbing-work, to a considerable extent, in batches of houses, as petty contracts. Cost of repairs to houses in the Napier Borough has averaged about £15 per house, and corresponding work in the county districts has averaged £22. STAFF. The staff of the Public Works Department is now almost as large as at any time in its history, although relatively to the expenditure and the number of employees it is less in proportion than it was ten years ago. It is apparent that a substantial reduction in the amount of loan-money which will be available for expenditure will necessitate a reduction of the staff. Already a very substantial decrease _in numbers has been effected. I desire to say that the various officers have carried out their duties in a commendable manner, often under conditions which were calculated to test their capacity. As appendices to this Statement honourable members will find full details of the principal works carried out by the Department, together with reports of the Engineer-in-Chief, the Chief Electrical Engineer, the Government Architect, and the Main Highways Board.

APPENDIX B.

ANNUAL REPORT ON PUBLIC WORKS BY THE ENGINEER-IN-CHIEF.

a The Engineer-in-Chief to the Hon. Minister op Public Works. 1 have the honour to submit the following report upon the various works under my control completed and in progress throughout the Dominion during the period from the Ist July, 1930, to the 30th June, 1931. As in previous years, the principal operations consist of the construction of railways, roads, and hydro-electric undertakings, in that order, followed by buildings, irrigation, lighthouses, rivercontrol, and other miscellaneous works. Although in the graph showing the ratios of the various subdivisions to the whole, telegraph-extension is shown as absorbing 5-16 per cent, of the total funds expended, this work, although paid for out of the Public Works Fund, is supervised and carried out, in the main, by the Telegraph Department itself, and is consequently not reported on here. A considerable amount of the building-work totalling 11-38 per cent, of our operations includes schools, which until recently have been directly controlled by the Education Department, but in future will come under your more direct control. Although a very considerable reduction was made part-way through the year in the scope of the railway-construction, this branch of the Department's work, in volume, is still far ahead of any other branch of the Department's operations.

North Auckland Main Trunk Railway. Rangiahua Section (24 m. 45 ch. to 38 m. 34 ch. ; length, 13 m. 65 ch.). —My report for last year detailed the extensive and costly work that had to be carried out stable railway formation along a considerable length of the unstable hillside. During the earlier portion of this year this section of the work drew to a conclusion —the last three large slips were removed, and the formation consolidated —and all other earthwork was completed. During the period that work was in hand 60,000 cubic yards of earthwork were handled, 40,000 being slip material, and the balance being excavation to make the Rangiahua Station-yard. All culverts are now complete. During the year 57 lineal chains of stone walls and 94 lineal chains of stone drains were made as part of the work to consolidate cuttings and fillings. Two miles of fencing were erected. One mile of platelaying was done, and substantial progress was made with the ballasting, the work done being equal to 6 miles of track completely ballasted. All bridge-work has now been completed, the work for the period being the building of a railway-bridge of total length of 130 ft. in plate-girder spans, and a heavy reinforced-concrete road-overbridge. A feature of the work has been the extensive reconstruction of the main highway, the need'for which arose through the way in which the railway location fouled the main highway. With the exception of 2| miles of metalling, this highway-reconstruction work is about complete. Ballast and road-metal is obtained from a basaltic-rock quarry at Okaihau operated by the Department. While operations were in hand this year the quarry delivered 26,274 cubic yards of crushed metal and 2,474 cubic yards of spalls. Construction work was suspended at theNNek Year,w k Year, and during the six months of [the year that works were in hand an average of 235 men had been employed. A few men were retained [after the New Year, cleaning up and reconditioning plant and finishing essential road-deviations. The work that requires to be done to complete this railway is briefly stated as follows : 3 miles of platelaying and ballasting, including Eangiahua Station yard; erection of Rangiahua Station buildings ; 10 chains of main-highway formation and 2J miles of metalling. Tauraroa Quaery. The installation of permanent plant to replace that destroyed by fire in the preceding year was undertaken, the installation being completed early in November last. A much smaller programme of work was undertaken this year than in previous years, practically the whole of the metal going to the Dargaville Branch Railway or to the Auckland-Maungaturoto Main Highway. With the closing-down of the railway-work at the New Year the quarry likewise had to be closed down. During the months that the plant was operating 11,800 cubic yards of metal of all kinds were crushed. Dargaville Branch Railway. This railway continued to make rapid progress during the year under review till construction was stopped at the New Year. By that time the formation had been completed, except for a subsidence at 2 m. 15 ch., the approaches to the Tangowahine Bridge at 10 ni. 20 ch., and the continued subsidence at the big bank at 13 m. 63 ch. At 2m. 15 ch. a single-span bridge is required, and at 13 m. 63 ch. it is anticipated that the filling is approaching a stable condition, probably requiring not a great deal of extra work to complete. Three steam-shovels were in continuous service. Culverting is complete to 15 m, 66 ch. Three railway-bridges of plate-girder spans, totalling 395 ft., were complete. Overbridge at 12 m. 37 ch. was built of hardwood timber. Platelaying was continued to 11 m. 70 ch., 1 m. 45 ch. being laid, and 2 miles of ballasting, first lift only, were don«. The Te Wharau Station yard was completed, with the exception of metalling, stock-yards, and gates. The goods service between Tangowahine and Kirikopuni, started the previous year, was continued, and from the 22nd September, 1930, a regular passenger service connecting with the Railway Department's services has been run. These services have been of great benefit to the Dargaville district. The passenger, mail, and goods service is still being continued. General construction works ceased at the New Year, but a forceoosf s fifty men has been retained during the rest of the year now reported upon. These men have been employed on cleaning up, reconditioning of plant, running of train services, and maintenance of works. During the first six months of the year dealt with in this report the number of men employed averaged 210. The work required to be done to complete this railway, and thus link Dargaville and the Kaihu Valley with the railway system, is as follows : 1 m. 50 ch. of formation of very light nature, 3m. 70 ch. of platelaying, 7 miles of ballasting, and erection of Whapu Bridge at 17 m. 20 ch. Napier-Gisborne Railway.—Waikokopu-Gisborne. Owing to the closing-down of construction work on the Waikokopu-Gisborne Railway at the end of 1930 active operations covered by this report represented six months' work only. During that period construction was pushed on vigorously, the average number of men employed being 792. My report of last year described the heavy nature of the work, particularly in respect to tunnelling, the three longer tunnels having a total length of 241 chains. These tunnels would thus control the time required for the completion of the railway, so the construction of the necessary service roads,

D.—l.

the ordering of air-compressing plant, and the erection of power transmission-line from Nuhaka up the Kopuawhara Valley to the points from which these tunnels would be attacked were energetically pushed forward. Everything was in readiness to start the tunnels when the decision was made to stop the work. Very substantial progress had been made with general construction operations, apart from the tunnels, and particulars of the work done are as follows : — Kopuawhara Section (12 m. 0 ch. to 33 m. 72 ch., Wairoa chainage; length, 10 m. 72 ch.).— Clearing has been completed to 31 m. 71 ch., and 308 chains of permanent fencing have been erected. Earthwork was proceeding very vigorously over the whole of this section until the closing-down of the work on the 14th January, 1931, a total of 104,857 cubic yards having been excavated during the period. The culverting of the section was pushed on vigorously ; 468 ft. of concrete culverts varying from 6 ft. to 18 in. in width, and 789 ft. of water-drives from 9 ft. by 9 ft. to 4 ft. 6 in. by 3 ft. were completed. No permanent bridging has been carried out on the section, but borings for foundations at 23 m. 22 ch., 30 m. 15 ch., and 33 m. 68 ch. were made, and a service trestle was completed at 23 m. 22 ch. Two miles of service road were formed, and 2 m. 20 ch. of metalling, and one road-bridge were completed. There were 9 m. 60 ch. of telephone-line built, and 5 miles of 11,000-volt transmission-line were erected. Wharerata Section (34 m. 60 ch., Wairoa chainage, to 14 m. 0 ch., Gisborne chainage ; length, 9 m. 75 ch.). —Co-operative contracts for the formation have been in hand over the whole section, a total of 129,382 cubic yards having been excavated up to the time of closing down and 947 ft. of culverts and 917 ft. of water-drives completed. The formation of the Wharerata Station yard at 14 m. 35 ch. was in hand, and several miles of service road in the Tikiwhata Valley and t.o the Coast Eoad tunnel were formed and partially metalled and culverted. A start was made with the construction of the tunnel at 18 m. 70 ch., 114 ft. of bottom heading and 44 ft. of top heading being completed, 16J ft. of tunnel being enlarged and lined. Gisborne Section (14 m. 0 ch. to Gisborne ; length, 14 m. 7-35 ch.). —The earthwork, which is of a light .character, has been in hand over the whole section, and during the year 39,302 cubic yards have been excavated, and marram-grass has been planted where the formation passes through sandy country. There were 120 ft. of culverts built, 65 ch. of permanent fencing completed, and the widening of the Pakowhai Stream finished. A start had been made with the erection of the Waipaoa Bridge at sm. 0 ch. The protection of one bank has been completed, three test piles cast and pile-driver, derrick, &c, assembled. General: The policy of providing good accommodation for the workers was carried on, and to date a total of 221 married quarters, 560 single huts, and a Y.M.C.A. hall have been built. Since the works closed down clearing-up work has been in progress, all rails have been taned or oiled, 'and plant overhauled, a great deal of the latter being transferred to other works. Gisbobne-Napier Railway.'—Napier-Wairoa Section. Putorino Section (10 m. 56 ch. to 37 m. 35 ch. ; length, 26 m. 59 ch.). —This section was handed over to the Eailway Department on the 6th October, 1930, and from that date maintenance and control of traffic was carried out by that Department, the whole of the Public Works organization having been moved forward to the Wairoa Section. The work carried out for the period before handing over was in the nature of cleaning up, small jobs in station-yards, fettling, fencing, repairs, and telephone-line renewals, and the evacuation of workers' accommodation to the section farther north. Traffic was dealt with throughout the period, and the volume was quite satisfactory. Since the earthquake on the 3rd February, 1931, a certain amount of work has been done on behalf of the Railway Department on a portion of this section, restoring damage to the track between Waikoau and Putorino. Wairoa Section (37 m. 35 ch. to 70 m. 67 ch. ; length, 33 m. 32 ch.). —The formation work on this section is practically completed, there being only the Kotemaori Tunnel and a few cuttings and banks to complete. Four steam-shovels have been employed during the period, and these, together with scoop teams and hand labour, accounted for the excavation of 99,500 cubic yards, the principal works being cuttings at 44 m. 23 ch., 44 m. 63 ch., 51 m. 0 ch., 51 m. 10 ch., and 52 m. 13 ch. At 51 m. 10 ch. work is being carried on in three shifts. The southern approach to the Kotemaori Tunnel has been completed, and the side drive running parallel to this cutting has been cleaned out and made sound by judicious trimming where required. The bottom heading through the Kotemaori Tunnel at 42 m. 15 ch. was pierced in September last, and from that date three shifts have been working from both ends enlarging and lining the tunnel. Progress at the south end since September, 1930, is 11-73 chains, and the work is completed back to 42 m. 26-31 ch. At the north end three shifts have been working on the breakdown and have completed 14| ch. of tunnel during the year. There is 7J ch. left to complete this tunnel, and now that the dispute in connection with tunnels generally has been finalized the work should be completed in about six months' time.

The Mohaka Tunnel was completed just after Christmas, a total of 11 ch. being driven and lined during the year. The principal work on the section has been the construction of the viaducts and bridges, all other works being co-ordinated as far as possible to enable these to be carried out progressively, the erection plant and cableways being shifted forward as required. The wind-screen at the Waikare Viaduct, the only work remaining here, has been completed ; but a certain amount of earthquake damage was sustained and will have to be repaired, as the piers and abutment at the south end were badly damaged, though, generally speaking, the structure stood up to the earthquake very well and can still take traffic. The Mohaka Viaduct, at 49 m. 40 ch., which towers 315 ft. above the river-bed, and consists of four 100 ft., three 80 ft., four 50 ft., and one 65 ft. spans, is now in hand, the foundations for the piers being well forward. The river piers, which consist of large concrete caissons sunk under compressed air, presented peculiar difficulties owing to their large size and the depth to which they had to be sunk, but fortunately there were comparatively few floods while the sinking was in progress. Good progress has been made with the land piers, and all foundations should be completed in three months. The steelwork for this viaduct is being fabricated in the Department's workshop at Tauranga, and is well in hand. The Maungaturanga Viaduct, at 51 m. 44 ch., consists of five 100 ft. and six 50 ft. spans, with a height of 220 ft. above river-level. All foundations and piers have been completed and the steel towers erected, leaving only the 100 ft. steel spans to complete. A feature of this work has been the construction and operation of the two overhead cableways for the steel erection. These cableways have given great satisfaction, and the method has resulted in quick and efficient work. They will shortly be shifted forward for a similar use at the Mohaka Viaduct. The formation, bridges, &c, on the section between Mohaka Tunnel and Wairoa were pushed on and completed in time to lay the permanent-way and allow the steel for the Maungaturanga Viaduct to be transported by rail. Waihua River Bridge, at 59 m. 31 ch., consisting of one 100 ft., three 50 ft., and two 40 ft. steel spans on concrete piers, is practically completed, all steel being erected during the year. Owing to a large slip blocking the Waihua Tunnel all steel had to be carted to the site by lorries. The only work yet to be done consists of guard-rails, sleepering, refuges, painting, and the general dismantling and clearing-up of staging. Ohinepaka Bridge, at 64 m. 7 ch., consisting of one 40 ft., four 30 ft., and one 25 ft. steel-plate girder spans on pile piers, was completed during the year. Ohinepaka Bridge, at 64 m. 47 ch., consisting of five 30 ft. plate-girder spans on pile piers, was also completed. Hurumua Bridge (65 m. 46 ch.), consisting of three 30 ft. and two 25 ft. plate-girder spans on pile piers was completed, except for full sleepering and spacing bars. Wairoa River Bridge, at 68 m. 59 ch., consisting of four 105 ft. steel truss spans and two 15 ft. plate girders on concrete piers with deep cylinder foundations, is now complete except for the placing of guard-rails at end spans. It is at present in use as a road-bridge pending the construction of the new bridge at Wairoa Township. Fourteen culverts have been completed over the section, and fencing has been practically completed throughout. On the southern end platelaying has been carried forward to 41 m. 63 ch., near the southern end of the Kotemaori Tunnel, and southwards to 51 m. 60 ch. near the Maungaturanga Viaduct, and a lift or more of ballast has been given to all track. The ballast for the section south of Kotemaori Tunnel is being obtained from Waikoau Pit, and it has been necessary to operate ballast-trains over the open railway to obtain this. Ballast for section north of Maungaturanga Viaduct has been obtained by dredging out of the Wairoa River near the railway-bridge. For the interventing portions ballast may be obtained ■ for probably first and second lifts from shingle deposits handy, and it can be topped oS with Wairoa River shingle after completion of the viaducts. A number of platelayers' cottages constructed of concrete blocks were very severely damaged by the earthquake, demonstrating that this class of construction is not suitable for an earthquake area. The Makomako Sawmill was in operation till the 7th November, when it closed down on account of the bush being cut out. The average number of men on the line during the period was 473. Waikokopu Branch Railway. The line from Wairoa to Waikokopu (24 m. 30 ch. long) has been maintained for traffic, and maintenance gangs have been employed fettling, &c, and attending to the repair of permanent structures. The only construction work has been the erection of cattle-stops at 10 m. 19 ch., two private crossings with four gates and one small bridge.

Ploughing and grassing in Ohuia Swamp, 0 m. 40 oh. to 2 m. 70 oh., left and right, has been completed for fire-break purposes. A daily service has been in operation, and all of the steel for the Maungaturanga Viaduct was landed at Waikokopu and railed through to Wairoa. Stratford Main Trunk Railway.—East End. Matiere Section (0 m. to 1.0 m. ; length, 10 m.)— This section has been complete for some time, except for a few minor details. General maintenance has been carried out. Ohura Section (10 m. to 19 m. ; length 9m. 10 oh.).—This section is also complete. Certain minor works were completed, and general maintenance was carried out. Tokirima Section (19 m. 10 ch. to 29 m. 70 ch. ; length, 10 m. 20 ch.).—During the year the formation and culverjdng have been completed, except for additions needed to four fillings. The tunnels on the section, six in number, are complete, the year's work comprising 28 chains of breakdown and lining. Two railway-bridges, comprising 195 ft. of plate-girder spans on ironbark pile piers, were built, and material is on the site for Tokirima Stream Bridge and for two road overbridges. Platelaying in 701b. material was done for 4J miles to just beyond Tokirima Station yard, and first and second lifts of ballasting have been spread for 5 miles and 4 miles respectively. >:*! Heao Section (29 m. 70 ch. to 55 m. 40 ch., on chainage from western end ; length, 3m. 50 ch.).— The work on this section is heavy, and most of the construction work now being done is concentrated thereon. To facilitate transport of construction material from the Heao Depot to the heavy work on this section, including the eastern end of the Mangatete Tunnel, a service tramway was built, transport being handled by small construction locomotives. Most of the culverting and stream-diversion work is complete, this latter ranging in size from 18 in. culverts to 10 ft. by 8 ft. water-drive. There are three crossings of the Heao Stream on this section of the railway, at all of which the concreting of foundations and piers is in hand. Tunnels.— Heao No. 1 and Heao No. 2 are both 8 chains long. The Heao No. 1 tunnel has bottom heading pierced and 2| chains of lining completed. The Heao No. 2 t,unnel is complete. At the Mangatete Tunnel (length, 55 chains) a commencement has just been made with the breakdown and the lining at the eastern end. The western end of this tunnel is being worked under the Stratford District office. It is anticipated that this tunnel will be complete by May of next year, and. the linking-up of the rails and the completion of railway, preparatory to handing over to the Working Eailways, will follow quickly thereafter. The stoppage of work for two months between April and June last occasioned a serious setback to construction operations. Had it not been for this the rails would have been into Heao Station yard by June, and all service transport would thus have been off the road before the winter conditions became adverse. Traffic. The Department is now maintaining a goods service from Tokirima Station, and a passenger and goods service from Ohura, linking up with the Main Trunk line at Okahukura. Goods are carried at through-booking rates, and the service is of much benefit to the district. The average number of men employed on these works during the year was 350. Stratford Main Trunk Railway.—West End. Raekohua Section (47 m. 40 ch. to 50 m. 60 ch. ; length, 3m. 20 ch.).—My last report indicated that this section had been completed as far as 50 m. 35 ch. During the year covered by this report some formation was done on Tangarakau Station yard ; 70 lb. rails were laid on the mam line, and first loop of this yard, from 50 m. 37 ch. to 50 m. 50 ch. ; and rails have been boxed in with ballast and a good running-top maintained from 47 m. 40 ch. to 50 m. 37 ch. Ballasting is now being done in the Tangarakau Station yard with ballast supplied by the Railway Department from Mount Egmont. All completed bridges on the section were painted during the year. Piers A, B, and Cof the Tangarakau Bridge were built, the construction being reinforced-concrete piles surmounted with a concrete pier. The steel-plate girders have been delivered, and preparations are in hand for placing them in position. The tri-weekly passenger and goods services were maintained between Tangarakau and Tahora, connecting with the railway system at Tahora. During the year a total of 15,000 tons of coal was hauled to Tahora from the Egmont Collieries siding at Tangarakau. Heao Section (50 m. 60 ch. to 55 m. 40 ch. ; length, 4m. 60 ch.).—Good progress has been_made on this section. The earthwork has been practically completed, though several cuttings are slipping badly. The bank between 50 m. 65 ch. and 70 ch. is narrow, and in the cutting at 50 m. 73 oh. 1,500 cubic yards is still to be removed out of an original total of 20,000 cubic yards. Prom here up to No. 1 tunnel, at 51 m. 15 ch., the service tram-line has prevented completion of the permanent formation, but the tram-line has been deviated to facilitate this work, which will be put in hand almost immediately. Earthwork in the Mangatotoko Valley, 51 m. 45 ch. to 52 m. 10 ch., is finished, and also in the Mangaone Valley, from 52 m. 65 ch. to 53 m. 47 ch., except for trimming of batters. In the Mangatete Valley, 54 m. 30 ch. to 55 m. 17 ch., all cuttings have been taken out, but several have given trouble with slips, two of which are still being worked. Tunnels.— No. 3 tunnel, 63| ch. long, was finished in March, 1931. The bottom heading of No. 4 tunnel (Mangatete Tunnel), which is now the only tunnel not finished, reached 55 m. 38-77 ch. in October, 1930, and was then stopped in order to make a start on concreting. Heavy ground at the portal necessitated 2 ch. of B section with lining 2 ft. thick. Lining is completed from the portal at 55 m. 16-60 ch. to 55 m. 24-45 ch. At 55 m. 20-50 ch. the tunnel comes to the surface of the ground and crosses a creek, which is being taken over the top of the tunnel. To give the necessary strength, for a length of 59 ft., the concrete lining was increased to a thickness of 30 in., a_ concrete invert also being built, and construction of a spillway over the tunnel is in hand. An electric locomotive is now in use in the tunnel in place of horses.

D.—l.

All fence-lines nave been cleared, and all fencing, except 150 ch., erected. The country being rough has made the work very difficult in many places. The 6 ft. by 4 ft. water-drives at 54 m. 51 ch. (length, 121 ft.) and 55 m. 16 ch. (length, 313 ft.) have been lined complete with face-walls. Twelve concrete culverts, of total length of 278 ft., were placed and completed. The piers for the Mangatete Stream Bridge at 54 m. 40 ch. have all been finished, and the plate girders have been delivered at Tahora. Seventy-pound rails have been laid from 51 m. 21 ch. to 52 m. 65 ch., and from 53 m. 47 ch. to 54 m. 30 ch.—a total of 2m. 27 ch. The greater part of this work was done on night shift, so as not to interfere with transport. The Mangaone Quarry was closed down in September, 1930, and all metal and sand for concrete have since been supplied from Te Wera Quarry. The main air-line was extended from 54 m. 30 ch. to 55 m. 15 ch., thus eliminating the compressor at No. 4 tunnel. The compressor in the Mangaone Valley which had been used to boost the supply during the day was shut down on completion of No. 3 tunnel in March, 1931, and all air is now supplied by the compressor in the power-house at Tangarakau. The power-house has run during the year without any trouble. With the completion of No. 3 tunnel the load was reduced and economies effected. The Raekohua Road has been maintained during the year. General. —-The number of men employed on this work was 294 at the beginning of the year and 190 at the end, the average number being 261. The reduction is due to the completion of No. 3 tunnel. The programme of work suffered considerably as a result of the recent stoppage of work for a period of two months, following on the men's refusal to accept the reduced contract rates fixed in accordance with the new basic rate of pay. However, in spite of this delay, the railway should be completed by about the end of June, 1932, if all goes well. Te Wera Quarry. —This quarry was worked continuously, except for one month when work had to cease, due to stoppage of work on the Heao Section. The total output of crushed rock was 19,904 cubic yards, the railway-works absorbing 60 per cent, of this quantity, the remainder going out on to roadworks. The average number of men employed in the quarry for the year was 20. Wellington - Tawa Flat Railway Deviation. During the past year construction work on this deviation, which has a total length of 7 m. 14 ch., has been actively prosecuted. My report for the preceding year explained the method of construction of the sea-wall required to protect from wave-action the embankment which is now being built in the harbour waters as the approach to No. 1 tunnel. This sea-wall is made of 5-ton concrete blocks and of heavy stone from quarry at Horokiwi. During the year this wall was built for a distance of 22 ch. to a height of 5 ft. above high-water level; the embankment itself was made to a height of 3 ft. above high-water level for a distance of 16 ch. (2 m. 9 ch. to 1 m. 73 ch.), and brought up to formation level for half-width from 2m. 25 ch. to 2m. 5 ch. (Note. —The chainage used in this report has its zero at site of proposed Bunny Street Station.) No. 1 tunnel of total length of 61-58 ch. is now complete. During the year the full enlargement of tunnel section and concreting of the lining respresented a progress of 20| ch. No. 2 tunnel is 2m. 53 ch. in length. The main heading was extended during the year 29 ch. from the south end and 26 ch. from the north end, leaving 14 ch. of heading to be completed. The pioneer heading which is being driven, as my last year's report indicated, to facilitate progress, advanced 28J ch. from the south end and 25 ch. from the north end, the distance between headings at the end of the year being 21J ch. The necessary connections were made between pioneer heading and main heading as progress required. Full enlargement and lining were completed for 22 ch. at the south end and 16 ch. at the north end, the total length of tunnel now completed being 68 ch. In addition, an equivalent of 8 ch. of enlargement has been completed at the south end, and has been timbered preparatory to concreting. Progress has been made with cuttings and banks beyond No. 2 tunnel, and, except for a gap at 6m. 72 ch., formation is now complete from 6m. 14 ch. to Bm. 26 ch. The road-diversion at 7m. 30 ch. and creek-diversions at 6m. 70 ch. and Bm. 10 ch. were completed. Four hundred and eighty-eight lineal feet of concrete culverts were built. Regarding bridges, the launching of steel-plate girders for bridges at 7 m. 25 ch., 7 m. 37 ch., 7 m. 51 ch., and 7 m. 63 ch. was completed, girders were bedded down and cleaned, painting is in hand, being completed at first two bridges named. During the year the average number of men employed was 435. Midland Railway. Murchison Section (63 m. 8 ch. to 85 m. ; length, 21 m. 72 ch.). —All work on the section between 63 m. 10 ch. and 67 m. 3 ch. at Gowan Station yard was completed during the previous year, but it has been maintained and departmental traffic run over it during the period. Up till the closing-down of this railway in January of this year formation work was proceeding very vigorously, and, with the exception of several cuttings, was practically complete to 82 m. The most important work on the section was the completion of the cutting at 67 m. 50 ch. This cutting, which governed the progress of platelaying and ballasting, was being excavated by means of a steam-shovel working two shifts, the spoil being deposited from a long trestle, and it was anticipated that it would have been completed inside six months.

31

D.—l.

At 69 m. 20 ch. and 72 m. 40 ch. there was also approximately six months' work remaining, and all the other gaps up to the 82 m. mentioned above would have been completed within the same time. The cutting at 72 m. 40 ch., which was being excavated by hand, with the assistance of pneumatic drills, was also being worked on shifts, the material going to form the approach to the Owen Kiver Bridge. Had operations been continued as anticipated a start would have been made with platelaying and ballasting within the next few months, and this would then have proceeded without interruption, at least, as far as Mangles Eiver, at 82 m., and probably to Murchison itself, at 84 m. 50 ch. Overbridges at 66 m. 60 ch. and 67 m. 59 ch. were completed, and approaches metalled, while the necessary foundation tests for bridges over Owen Eiver and Doctors Creek were completed. The road-deviation from 69 m. 10 ch. to 69 m. 50 ch. along a steep precipitous rock bluff was completed and metalled. Nine concrete culverts, varying from 12 in. wide to 8 ft. wide, were built. One hundred and sixteen single men's huts were erected during the period, and the machine-shop installed and fitted at Grassy. Since the work has stopped all plant has been collected, overhauled, and stored or transferred where necessary, fencing restored, and works cleaned up generally. The average number of men employed over the period was 298. Westport-Inangahua Railway. Cascade Section (5 m. 70 ch. to Bm. 78 ch. ; length, 3 m. 8 ch.). —This section, although practically complete, is still under the control of the Public Works Department, and has been maintained by it for the coal traffic from the Cascade Mine. Hawk's Graq Section (8 m. 78 ch. to 18 m. ; length, 9m. 2 ch.). —All bushfelling and clearing has now been completed on this section, and the earthwork has been finished for a total distance of 7 m. 43 ch. The portions unfinished involve in most cases long leads, where the progress is slower. At such places the actual excavation is carried out by manual labour, but the haulage of spoil is effected by means of small petrol-locomotives, five of these of a special type being employed on this section, each hauling a rake of from four to six steel side-tipping trucks. The nature and location of the cuttings exclude the use of any mechanical loading-devices. From 11 m. 10 ch. to 11 m. 26 ch., where the first petrol-locomotive is stationed, there are several cuttings which block the advance of platelaying, as all the material from these cuttings is required to fill a large bank of 50,000 cubic yards between 11 m. 43 ch. and. 11 m. 54 ch., and none of it can be spoiled. To expedite the completion of this portion of the line, shift-work was started early in the year in the advance cutting. This involved the installation of an electric-light plant to illuminate the rugged cuttings and the long leads, and to enable tipping to be carried out from the trestles with safety at night. A start was made with the driving of bottom heading for the tunnel at 13 m. 41 ch., but unfortunately a disastrous accident occurred, involving the death of three men. Following this, work was held up for some time on account of the negotiations regarding tunnel prices. The parties have now been reorganized and a fresh start is being made. In order to facilitate the supply of shingle and cement for tunnel-lining and for adjacent culverts and bridges, a cableway transporter has been erected at the tunnel-mouth, by means of which the shingle and cement will be conveyed across the river. Four culverts and a concrete retaining-wall have been constructed and several are in hand, but the transport of shingle across the river is expensive, and a great deal of the culvert-work has to wait until the rail-head advances. The concrete-metal supply for this section of the railway is one of the difficult problems, on account of the inaccessibility of the structures to be built. As far as possible the aggregate will be brought by rail from a shingle-pit 3 m. out of Westport, where a stock of good metal has been accumulated throughout the year. Bridges and culverts will be taken in a face as the railroad advances, but, as this cannot proceed very quickly, other means of obtaining metal in the isolated sections ahead of the rails have had to be resorted to. In several places shingle from a convenient river-beach has been carted by lorry to a point on the Main Gorge Eoad where a cableway transporter has been erected, the shingle being taken over by this means and then redistributed over the completed formation to the sites of such bridges and culverts as were accessible. The most important work on this section, however, has been the construction of the Cascade Creek Bridge at 9m. 0 ch. This bridge is 446 ft. in length, and consists of five 80 ft. and one 40 ft. spans, all on a 7?? ch. curve. The piers are of concrete, each founded on three concrete cylinders arranged in the form of a triangle. This work has proceeded steadily, and the gorge has been spanned by a temporary bridge, which also serves as a staging for the sinking of the cylinders, the construction of the piers, and erection of the steel superstructure. Cylinder-sinking at one pier has been completed, and the others are well in hand. The erection of the temporary bridge, although primarily designed to facilitate the constructionof the permanent bridge, enables the construction train to deliver plate-laying material to the rail-head at 10 m. 20 ch., as well as to convey concrete, metal, and material to structures ahead of Cascade Creek. It is expected that the permanent bridge will be completed in about twelve months. At 10 m. 24 ch. the construction of a three 30 ft. spans steel-girder bridge on concrete piers is in hand. The excavation for the piers is almost completed, while the combined temporary bridge and staging is in hand.

32

D.—l.

A feature of all the bridge work on this railway is the necessity, owing to the impracticability of constructing service roads, for the erection of temporary bridges at each gulch to enable the rail-head to be carried forward and construction material delivered ahead while the actual construction of the permanent bridge is in hand. Another suspension bridge, 530 ft. long, was constructed across the Buller River at 15 m. 24 cL, to assist the men in reaching their work on the opposite side of the river from the Camps. These suspension bridges, of which there are now three on this section, have proved of great value in floods, which occur frequently in this river, as shown by the fact that the rainfall for this locality for the past twelve months was 169-90 in. The workshop at Tiroroa has had a very busy year, effecting repairs to vehicles and items of plant, as well as the making-up of ironwork for bridge and general construction use. Orikaka Section (18 m. to 27 m. 34 ch. ; length, 9m. 34 ch.).—Good progress has been made with the formation work on this section during the year, a large number of parties having been transferred from completed contracts on the Hawk's Crag Section, much of the earthwork on that section having been completed early in the year. The whole section has been fully manned throughout, and a total of 4m. 40 ch. has been completed. There are several very large earthwork undertakings on this section, there being fillings of 60,000 and 50,000 cubic yards at 20 m. 0 ch. and 20 m. 62 ch. respectively. At the first of these places the material required has to be borrowed by widening along the line, and arrangements have been made using petrol-locomotives and steel tipping-trucks to build the bank in two lifts. At the second bank a drag-line scraper is being used with good results to borrow material and deposit it in the bank. Another bank, containing 70,000 cubic yards, between 26 m. 42 ch. and 27 m. 12 ch., in the vicinity of the Inangahua Station yard, is being expedited as" much as possible, as it forms the approach to the combined road and railway bridge across the Inangahua River, a number of co-operative parties, with petrol-locomotives and trucks, as well as. wheeled scoops and drays, being employed. Some of the cuttings on this section, which are in heavy precipitous country, have given trouble, owing to the large quantities of debris which have been loosened by the earthquake of June, 1929, slipping down on to the formation. Portion of the section from 19 m. to 23 m. is very inaccessible, and special camps have had to be established and the transport of supplies provided by the Department. A suspension bridge across the Buller River, 540 ft. long, is being erected at the 19 m., and will greatly facilitate access to the men camped there. The average number of men on both sections for the period was 414. South. Island Main Trunk Railway.—North End. Clarence Section (56 m. to 76 m. ; length, 20 m.).—-Good progress has been made with the formation on this section, all work, with the exception of that at the Blue Slip, being practically completed. This slip, which extends from 60 m. 61 ch. to 61 m. 8 ch., has been vigorously attacked by means of two steam-shovels, and, although it is anticipated that a considerable amount of work will have to be carried out before it is stabilized, still good results are being obtained. The formation of this section has been comparatively light, a considerable length being through the sand areas, which have been stabilized by extensive marram-grass planting both on the batters of cuttings and banks, and on the adjacent reserves. It is intended to follow up this planting by the establishment of a belt of trees to check any further wind-action. A feature of the year's work has been the large number of concrete culverts constructed, sixteen large concrete-pipe culverts, with a total length of 483 ft., and twenty-four flat-topped and arched culverts, with a total length of 394 ft., varying from 3 ft. to 10 ft. by 10 ft. At 62 m. 26 ch. concrete abutments on piled foundations for a 30 ft. steel-plate girder have been built, and a temporary superstructure erected to enable platelaying to proceed pending the supply of the steelwork. Kekerangu Stream Bridge : At 63 m. 15 ch. concrete piers have been erected. Ihe superstructure will consist of five 50 ft. and one 25 ft. plate girders, but in view of the delay in the supply of steel it has been necessary to erect a temporary wooden superstructure here also. Deadman Stream : At 67 m. 37 ch. the concrete piers which are built on piled foundations have been partly completed, all pile-driving being finished and four caps cast, the bridge consisting of five 30 ft. spans. Woodbank Stream Bridge, at 68 m. 66 ch., consisting of three 25 ft. steel-plate-girder spans, is in hand, the piles for the foundations having been cast and raker piles driven at abutment A. At the Washdyke Stream Bridge, at 69 m. 71 ch., consisting of four 30 ft. steel-girder spans on concrete abutments with piled foundation, the pile-casting is in hand. Owing to the close proximity of the road and railway, a number of road-deviations have had to be constructed on this section. During the period Im. 60 ch. were formed and metalled. Three mile of fencing have been erected. Platelaying was carried on from 60 m. 37 ch. to 64 m. 3 ch, and ballasting is well in hand over this distance, and at the present rate of progress it is hoped to have the rails to the Clarence by Christmas time. . Kaihoura Section.— Construction work on this section has been put m hand in earnest only during the last six months of the period, but it was then strongly manned by parties finishing up on the Clarence Section. The first 5 miles pass through sand areas, which have been planted with marramgrass similarly to those dealt with on the previous section. Although the first 6 m. of this section is comparatively light, the following, 8 m. are the heaviest on the section, comprising as it does the well-known Ohau Bluff portion. Owing to the-bluffs coming

3-D. 1.

33

D.—l.

very close to the sea, heavy cuttings and road-deviations are necessary to provide for both railway and road. A total of 4 m. 11 ch. of formation and 35 ch. of road-deviations have been completed, while 1 m. 19 ch. of the latter are in hand. Twenty-four culverts, varying from 18 in. to 10 ft. by 5 ft., have been constructed, with a total length of 924 ft. A series of borings at all the bridge-foundations on the section has been carried out by a Keystone boring plant, but no work has yet been started on the actual bridge-construction. The following buildings were erected on this section during the year : —Office, store, smithy, and carpenter's shop, garage, fitting-shop, recreation-hall at Wharanui and at Camp No. 8, twenty-nine single huts, and twelve married men's cottages. The average number of men employed on both sections during the period has been 368. South Island Main Trunk Railway.—South End. Conway Section (44 m. 20 ch. to 56 m. ; length, 12 m.).—The main activity during the year has been the prosecution of the large cuttings on this section. During the period approximately 9| miles of heavy grading has been completed, a feature of the work being the comparatively large amount of mechanical plant which has been successfully employed, six steam shovels, two drag-lines, and eight locomotives having been utilized. Although a portion of the plant has only recently arrived on the work and been put into operation immediately prior to the close of the year under review, a total of 187,851 cub. yd. has been shifted by mechanical means. The total yardage of spoil excavated by all means during the year was 345,378 cub. yd. Of the formation work on this section the most important unfinished portion is between 48 m. 4 ch. and 48 m. 50 ch. On the original plans this was shown as a tunnel, and a special contract was advertised and tenders invited for its construction by special contract. On going into the matter further it was found that it was more satisfactory to make an open cut in place of a tunnel. This has now been done, the present arrangement being to treat it as an open cutting and excavate it by means of a drag-line. By this means it is anticipated that a considerable saving can be made over the tunnel proposed. A very extensive programme of culverting has been carried out during the year, 1,700 lineal feet of pipe culverts varying in diameter from 12 in. to 30 in., and 1,151 ft. of arch and flat-topped culverts varying from 3 in. to 9 in. in width having been completed. The nature of the country lends itself particularly to the use of water-drives in place of culverts at many of the heavy fillings, 1,200 lineal feet of drives, varying from 6 ft. by 4 ft. to 9 ft. by 6 ft., being completed and 630 ft. being in hand. No bridge-work has been put in hand, but test piles have been driven at the Leader River Bridge at 44 m. 63 ch., and for the Conway River Bridge at 50 m. 56 ch. Plans have been prepared and material has been assembled on the site in readiness to commence construction. The road-overbridge at 47 m. 45 ch., consisting of a single-span concrete skew-arch, is well in hand. Nine miles of permanent fencing on both sides of the Railway Reserve have been completed. Oaro Section (56 m. onward). —The formation along 4 m. of this section has been opened up, and approximately 1 J m. have been completed. There are on this section 2m. or 3 in. of very light formation, but, practically speaking, this comprises the only really easy portion of this southern section. About \\ m. of grading has been completed, and the culverting is in hand. General. —A thoroughly up-to-date workshop and plant-depot has been established at Parnassus, and all repair work for the extensive mechanical equipment is now being carried out locally. Sixty-one married quarters for workmen and 134 single men's huts, as well as two staff cottages, have been built. The necessary temporary buildings for the prosecution of the work, consisting of fitting-shop, carpentering, plumbing, and blacksmithing shops, store, benzine-store, cement-shed, and office, together with the various miscellaneous small sheds incidental to a large construction work, have been built. A total of 300 men have been employed on an average during the year.

SURVEYS OF LINES UNDER CONSTRUCTION. South Island Main Trunk Railway.—South End. During the period trial lines were run from 53 m. to 73 m. 30 ch., and permanent pegging was completed from 53 m. to 63 m. 15 oh. South Island Main Trunk Railway.—North End. The permanent survey has been completed and plans prepared from 76 m. 0 ch. to 88 m. 0 ch. Trial survey is completed to 97 m. 0 ch., and work is in hand for a further 8 m. 48 ch. Midland Railway. The survey of the permanent line on the Murchison Section has been completed, and continued to 88 m. 0 ch. on the Maruia Section. Survey work was closed down simultaneously with the ceasing of railway-construction.

HYDEO-ELECTEIC WOEKS. Arapuni Power Development. The position at Arapuni on the Ist July, 1930, the beginning of the year covered by this report, was that all construction operations had ceased as a result of the earth-movement that took place on the 7th June. The position of the works at that time was that the power-house structure had been completed, with the exception of a few details ; and three turbines and generators, together with all the necessary switch-gear, cables, and transformers, had been erected and were in service. Measures to divert the surplus water from the forebay into the gorge by the construction of Nos. 7 and 8 penstock tunnels were well advanced, and preparatory work in connection with proposals to protect the rock at the falls in the overflow-channel was almost completed. No. 4 penstock tunnel was in hand, the excavation having been finished. Owing, however, to the serious position due to the damage resulting from the above-mentioned earth-movement, the Arapuni Lake had been emptied, and the station went out of service from the 11th June. Construction operations at once ceased, and were not resumed until December last. Investigations. —lnvestigations were immediately commenced as to the cause of the earth-movement. This work consisted of the clearing of a deposit of sand from the forebay, and the excavation of a series of small tunnels and shafts situated in the vicinity of the power-house and spillway structures : 4,334 ft. of drive and 208 ft. of shaft were completed for this particular purpose. Well-boring equipment was utilized to sink a number of investigation bores at the sides of the power-house, at the forebay, headrace, and main dam, a total of 2,404 ft. of deep hole being drilled. A technical committee, consisting of officers of the Scientific and Industrial Eesearch Department, the Director of the Geological Survey, and one outside geologist, visited the site, made a thorough investigation, and reported on the geological aspect of the movement. The whole of the information collected was then made available for Professor Hornell and Mr. Werner, two Swedish experts, who arrived at the invitation of the Government on the site at the end of the month of August, 1930. A thorough examination was made of the locality, of the conditions, and the nature of the rock ; and a report was subsequently made to the Government outlining their opinion of the cause of the movement and the nature of the remedial measures necessary to effectively, repair the damage to the works. Restoration Measures. —Professor Hornell's recommendations were accepted by the Government, and authority was issued during the month of December to proceed with the reconditioning of the station, when arrangements for the necessary staff and equipment were immediately put in hand. The major items of work were commenced on three shifts during January, and continued on that basis. By the end of the year —that is, the 30th June—the various works for the reconditioning of the headrace and forebay were well in hand. The lining of the overflow-channel with concrete has been commenced and the excavation preparatory to concreting the falls is almost completed. At the dam, grouting operations have been carried out on a large scale, and a commencement made with the excavation of a shaft for the emergency gates of the diversion tunnel. The reconditioning of the existing tunnel-gates is well forward. At the power-house the lower section of the foundation for No. 4 unit has been concreted and a start made with the erection of the turbine. No. 4 penstock tunnel is being lined, and the excavation required for the power-house extension had been recommenced. Details of the work carried out are as follows :—■ Penstock Intake Structure. —Eepairs are at present in hand, and as yet have been confined chiefly to the grouting of the rock comprising the foundation of the structure, and to the reconditioning of the damaged concrete by grouting and reinforcing with steel rods. This work is well forward. Drainage-tunnels. —The investigation tunnels driven from the water-level in the Gorge have been utilized as portion of a system of drainage-tunnels. A total of six tunnels, running at right angles to the line of the gorge and the headrace, have been provided for, and are situated at approximately 8-chain intervals between the up-stream end of the headrace-lining and the falls structure. These tunnels are provided for the purpose of draining the rock underneath the headrace, the forebay, and overflow-channel, and the block of country situated between those works and the gorge. The tunnels are nearing completion, a total of 6,960 lineal feet having been excavated. Reinforcement of Country at Junction of Penstock Intakes and Spillway. —This work is almost completed, and is being effected by the drilling, with special equipment, of a series of long horizontal holes up to 100 ft. in length, the inserting of steel rods into the holes, and subsequent pressuregrouting. Preparatory work in connection with the provision of a reinforcing concrete block at junction of spillway-weir and penstock intake structure has been finished. Crack in Headrace. —Strengthening and sealing the country along the line of the crack in the rock under the headrace and forebay has been in hand for some time and is almost completed. The work consists chiefly of drilling a series of 70-ft.-long inclined holes into the rock intersecting the crack below the surface, placing steel rods in the holes, and pressure-grouting. Headrace and Forebay Lining. —The preparation of the headrace and the placing of the special lining comprises one of the major works of the remedial measures, and consists of the clearing for, and construction of, side banks, the placing of porous layers, the laying of 35,000 square yards of bituminous mastic into which sheet iron is to be embedded, and the construction and laying of protecting concrete slabs. The preparation of the foundations for the new work was commenced with three shifts early during the month of January, and has been completed. Subsequently the construction of side banks was commenced, plough and scoop teams, supplemented by mechanical equipment, being used for the purpose. The construction of the banks is 85 per cent, completed.

43

D.—l.

The trimming of the side slopes preparatory to the placing of the porous layers has been commenced. 90,500 cubic yards of excavated material has been handled and 2,567 ft. of drainage-pipes have been placed in connection with this section of the work. Subsequent to the clearing of the floor of the headrace and forebay all depressions were filled with concrete or with spalls and adequately drained, followed by the placing of the porous layers, which have been 60 per cent, completed. The concrete cut-off wall to cut of! seepage, situated at the upstream end of the headrace-lining, has been completed, as is also a short curved wall situated at the junction of the eastern embankment of the penstock intake structure. 829 cubic yards of concrete have been placed in these two structures. It is proposed to carry out the bituminous lining of the headrace and the making of the concrete paving-slabs by contract, and at the end of the year plans and specifications had been prepared and tenders invited. Headrace-drainage. —A drainage-gallery, consisting of two shafts and a series of drives at various levels situated adjacent to the up-stream end of the headrace-lining, was commenced towards the end of the year. This gallery will ultimately be connected to an up-stream drainage-tunnel, which will serve as an outlet for it. A drainage-trench along the centre-line of and situated inmediately beneath the headrace-lining has been completed, and consists of a 6 ft. by 3 ft. trench, in which 1,630 lineal feet of 2 ft. concrete pipes were laid and covered with spalls. The outlet of this drain, consisting of 625 lineal feet of concrete-lined shaft and tunnel, will discharge into the gorge near the power-house. Main Dam. —Drilling and grouting of the country, comprising the abutments of the main dam have been in hand for some months, and satisfactory results have been obtained. Well-boring plants are being utilized to drill vertical holes, and special percussion-drilling equipment, operated by compressed air, for the inclined and horizontal holes. Drilling and grouting of vertical holes in the abutments are well advanced, but several months' work of horizontal drilling remains to be done. Clearing of the clay from the surface of the rock and guniting the western abutment of the dam was commenced towards the end of the year, but owing to the action of the severe frosts experienced, the work has been postponed until the spring and summer seasons. Preparatory work in the nature of excavation in connection with the provision of bitumen seals between the dam and the rock abutments is well advanced. Diversion-tunnel. —The diversion-tunnel which was opened during June, 1930, for the purpose of emptying the Arapuni Lake has been continually in service since then for the discharge of the Waikato River, with the exception that on a few brief occasions the gate-valves have been closed for testing and observation purposes. During the year several inspections of the condition of the concrete lining of the tunnel have been made, and it.is found to be in a very satisfactory condition. Large pieces of rock that had accumulated at the entrance of the tunnel during the emptying of the lake were cleared, and considerable trimming of the unstable portions of the clifi above the tunnel intake was carried out. Work has been commenced on the shaft required in connection with the emergency gates that are to be installed. A pilot shaft from the surface into the crown of the tunnel has been completed, and the enlargement to full size of the shaft has been commenced. One single gate of massive construction is proposed, which will be fabricated overseas. The installation involves the construction of a shaft of liberal dimensions, lined with reinforced concrete, extending from the ground surface for a depth of 162 ft. to the invert of the existing tunnel. The construction of the shaft and a small section of the concrete foundations for the gate-frame may be done while the tunnel is in service, but the completion of the gate-anchorages and the erection and installation of the gate-frame and lifting equipment must be left over until the lake has been filled and the tunnel dewatered. The whole work of the construction of the shaft and gate-chamber, fabrication, erection, and installation of gates will be of considerable magnitude. Repairs to the bases of both the existing gates have been undertaken and are well forward. This involved the raising of both gates, and the dismantling and replacing of the lower section of each. Overflow-channel. —Reconditioning of the upper section of the overflow-channel situated between the spillway extension and the drop weir has been completed. This particular section of the work was limited to the trimming of the rock and covering the whole surface with a 12 in. layer of reinforced concrete. 1,355 cubic yards of concrete were used for the purpose. The major or lower section of the work extends from the drop weir to the upper section of the falls structure, and is 960 ft. in length. The channel on this section is being widened to 150 ft. and the alignment improved. Both the floor and the sides are to be protected with a 12 in. layer of reinforced concrete, and excavation and concreting operations are at present in hand, the former being well advanced. 1,036 cubic yards of concrete, 22 tons of steel, and 5,550 cubic yards of excavation have been handled to date. Protection of Waterfall. —Operations were recommenced on preparations for concreting the falls immediately after authority was obtained for proceeding with the general works of restoration. The protective works are extensive, and generally consist of the trimming of the excavation of the foundation rock to such a shape and to such limits as will permit of the construction of a stream-line reinforced-concrete structure of such dimensions as will accommodate the discharge of 30,000 cusecs. A drainage-gallery, together with a comprehensive system of porous drains, is included in the work ; also the strengthening of the foundation rock by steel rods and pressure-grouting. Excavation work was commenced on three shifts during January, and has proceeded along these lines for the remainder of the year. On the upper section of the structure excavation has been completed and concreting work commenced. The lower section is more extensive than the upper ; larger quantities of excavation and reinforced concrete, and the dewatering of a large pool, being involved. Subsequent to the trimming of the batters, some of which were 180 ft. in height, pumping equipment was installed and the pool dewatered. Pumping was greatly facilitated by connecting the discharge from the pumps to a drainage-tunnel, by which means the water was carried directly to the Arapuni Gorge. The pool was effectively dewatered during the month of April, and by continual

44

D.^-l.

pumping the water has been kept well below excavation-level. Excavation of the surplus material from the bed of the pool was then proceeded with, and by the end of the year was nearly completed. 39,000 cubic yards of excavated material have been handled since the work commenced. Strengthening of the foundation rock is being effected by drilling and grouting a series of 20-ft. holes, into which steel rods are being inserted. This work is well forward. Concreting operations which comprise the chief work remaining have commenced. A drainage-gallery, consisting of a shaft and a series of tunnels at various levels situated beneath and a little up-stream of the upper crest, is now in hand, and is being connected to a portion of the porous-drain system by two vertical steel-cased boreholes. The whole of the work of protecting the falls is timed to be completed simultaneously with the remaining remedial measures. Grouting—Gmuting of the country at the sites of the dam, headrace, penstock intake, spillway, and the falls is recognized to be one of the important sections of the operations at Arapuni and during the last six months a total of 56,000 ft. of holes has been drilled by well-boring and percussiondnllmg equipment for this purpose. Power-house Extensions. —The draught-tube and concrete foundations for No. 4 unit have been completed to the level of the under-side of the turbine scroll casing, and the erection of the turbine has actually been commenced. The remainder of the equipment, consisting of the main valve, generator, governor, and transformers, has been delivered. The work of steel-lining No. 4 penstock tunnel and the auxiliary pipe, contracts for which were cancelled when the station went out, of service has been resumed by the Dunedin Engineering Co. Concreting between the steel lining and the' country is being carried out by the Department's own forces, and is following close behind the steel erection. Work on the power-house extension excavation has been resumed as a preliminary to clearing a space for foundations required for two 450 kw. independently driven auxiliary units, which are at present being manufactured overseas. General—Two small permanent cottages have been erected in the permanent village, and have been occupied by staff. Six hundred men, exclusive of staff, were employed at the end of the year being reported upon, most of whom are engaged on shift-work. The average number employed since work resumed on the 13th December last was four hundred. The constructional programme provides, subject to finance being available, for the station, with the additional unit, to be in service by the winter of 1932. Waitaki River Power Development. Dam.— When the last annual report was written the chief work in hand on this scheme was the dewatermg and excavation of the second, or North, coffer-dam, which extends from the first, or central, coffer-dam to the Canterbury River bank. This coffer-dam encloses the deepest section of the dam within the river-channel, but by the end of November the entire excavation within the coffer-dam was completed, and the concrete in the dam was placed to the height of ordinary summer river-level, at which level it will remain for some time. While this concreting work was in progress Professor Hornell visited the works, and after consultation with him it was decided to extend the dam by an apron some 25 ft. down-stream, and also to deepen the cut-off wall on the up-stream side. Fortunately, the cofier-dam was still intact, so that this work could be done without much extra expense. When the work on the down-stream extension was, however, about half completed in February last, a big flood occurred and caused a considerable amount of damage to the coffer-dam and other temporary works. This occasioned a good deal of delay and disorganization of the work, even though it gave an opportunity to overhaul and redispose the pumping and other plant in readiness for the next stage of the work. When repairs and overhaul had been effected and the river had subsided to normal the concreting of the apron was completed. . Eleven openings or sluices were left in the concrete of the dam to divert and control the river during the third stage of dam-construction in the river-channel on the Otago side. These openings for the passage of water will later on be closed, first by dropping temporary steel gates in front of them, and then by filling them up with concrete. While the concreting of the dam in the coffer-dam was in progress up to river level, a section of the dam at the Canterbury end,. 80 ft. in length, was completed almost to full height. A considerable number of model tests has been carried out to determine the most suitable shape to divert the water overflowing near the Canterbury end back to the river-channel, and the results have been most valuable. On the south, or Otago, river-bank excavations are in progress over the length of the dam between the river and the power-house. In addition to this work, a 36 ft. length of dam in this section is being constructed as close to the river-bank as it is practicable to excavate without danger. Unfortunately, the foundations for portion of the dam between the river and the power-house are at a greater depth than it was expected they would be, and increased quantities of excavation and concrete will be necessary. On account of the delays caused by the extra concrete-work within the north coffer-dam, and the serious floods in February, as well as restrictions due to the present financial position, it was decided that the original proposal to construct the third coffer-dam and complete the dam within it during this winter would have to be abandoned, and that work be concentrated on the section of dam on the Otago bank. While this will delay the time of completion, it is not so serious as it might have been, as the additional work caused by the greater,depth of foundation on the Otago side would haveS caused some delay in the original programme in any case. It also allows of the cut-off wall on the up-stream face of the dam, which has been increased in depth, being partially excavated by tunnelling methods, thereby shortening the time during which the third coffer-dam will be exposed to flood risks

45

D.—l.

This may prove to be a very important consideration indeed if heavy floods are experienced, and one that might easily result in a good deal of economy. The quantity of concrete that has been placed in the dam to date is 27,277 cubic yards. The quantity of excavation for the dam, apart from that involved in the coffer-dam, that has now been done is 104,000 cubic yards. Power-house —The excavations for the power-house, which involved the removal of 60,000 cubic yards of rock and surface stripping, were completed during the year. In June, 1930, the excavation had progressed far enough to commence concreting, and from that date to the present time over 29,000 cubic vards of concrete have been placed in position. _ The work here has been planned in order to give precedence to the foundations that enclose and support the two turbines which comprise the first installation, whilst the remaining foundation work is being completed to such a stage as will allow the three additional power units which complete the station to be installed, when required, with very little structural work. In April last a commencement was made with the installation of the turbines, and this work has now progressed far enough to permit of the surrounding concrete being completed to the level of the generator floor. Simultaneously the main columns at the other end of the building have been concreted almost to full height, and forms have been placed and concreting is in progress in each ol the fifteen penstock4ucts. In the power-house to date 29,346 cubic yards of concrete have been placed, 898 tons of reinforcing-steel have been bent and 967 tons fixed in position, while 1,363,000 superficial feet of timber has been used on the work. Tail-race —To the 30th June 70,000 cubic yards had been excavated from the tail-race. By the aid of pumping, the work, although mostly below river-level, has so far been done under dry conditions, and, in order to give employment to as many men, with as little machinery as possible. This method will be continued until it becomes uneconomical, when mechanical plant will be employed. The gravel excavated from the tail-race now constitutes the mam source from which the aggregates for concrete are derived. . . General —The service railway from Kurow to the works has been adequately maintained, and since this railway came into operation in December, 1928, 25,531 tons of materials and 3,500,000 superficial feet of timber have been carried. Charges based on tariff rates are debited to the particular section of the work to which transported materials belong, by which means the capital cost of the railway should be extinguished when the works are completed. To date about half the cost has been written oft m this way All centres of activity at the works have been connected with this railway and interconnected with one another, and this provides a rapid, safe, and economical solution to the problems of transport. Six locomotives are in service day and night, and they have almost entirely obviated the employment of motor-vehicles. - ~,• i ~ n ,i. To retain access to sheep-stations which will be cut off by the reservoir behind the dam on the Canterbury side of the river, a large steel bridge is in course of erection. This is a cheaper and better proposal than the formation and maintenance of an extensive deviation of the present road, which was considered as an alternative. During a period of exceedingly low water m the river last August the foundations to the concrete piers of the bridge were, by a week s concentrated eflort, placed in position, thereby greatly simplifying what would in normal years have been a difficult task. A contract for the fabrication of steelwork has been let, and it is anticipated that the substructure will be completed and a start made on the erection of the steel-girder spans next December. _ Permanent buildings are being erected in concrete blocks, and during the year ten residences, a large hostel and a garage have been completed, as well as the necessary road access to these, and fencing water-supply, and drainage. During the year the permanent steel-tower transmission-lme from Glenavy to the works was pushed on, one of the circuits was completed, and the new line came into service at the end of June. This obtaining of power direct from Lake Coleridge terminated the contract for supply from the Waitaki Power Board. The whole of the extensive plant on the works is now well supplied with power and is working with greater efficiency. To assist towards the relief of unemployment, however, work, where possible, is being carried out by manual labour rather than by mechanical means, whenever such a course can be economically justified. The number of employees during the year has varied between 1,000 and 1,240, including transmißsion-line workmen. Provision has been made for separate accommodation for 233 married men and their families, while huts and hutments to the number of 434 were provided for single men or those without their families.

EIVEE IMPEOVEMENT AND PEOTECTIVE WOEKS. Waihou and Ohinbmuei Rivers Improvement. As was the case the previous year, the chief work carried out during the year just ended has been the raising and strengthening of the upper Waihou stop-bank system. The stop-banks are being raised and strengthened by adding a banquette on the side remote from the nver-channel. In addition, the berm between the stop-bank and the river-edge is being graded, borrow pits filled m, and the growths of blackberry removed. Two l|-cubic-yard dragline excavators have been continuously employed on this work, and have made good progress. There is not much of this work now to do, save the cleaning-up of the berm. The reconditioned stop-bank and berm are being harrowed and grassed as work is completed. The completed work represents that portion between Ngahina and Tirohia stop-banks, and has resulted in an immense improvement to the flood-carrying capacity of the river.

46

D.-l.

On the lower Waihou maintenance has been carried out; all the flood-gates have been overhauled, cleaned, and painted. Five small culverts complete with flood-gates were installed under stopbank between Netherton and Turua. The whole of the construction work on the lower Waihou—i.e., from Ngahina down-stream to Huirau Road and Wharepoa Ferry —is finished. On the Ohinemuri River general maintenance has been carried out, and deepening and enlargement of major drains has been done by drag-line machine. The plant has been efficiently maintained. * The average number of men employed on these works was fifty-five. Taieki River. My report for the previous year indicated that, with the exception of some improvement work required to the contour channel, the scheme of protection works was completed. During the year covered by this report the improvement work on the contour channel has been completed. This extended over a length of four miles, the work consisting of deepening and enlarging the channel, the work being done by drag-line excavator. Provision has been made for spillways, so that the peak of flood-discharges will be released from the contour channel without damage to the channel. The water so escaping will reach the pumping-station by other canals or drains and be there pumped to Lake Waipori. The whole of the work to be carried out by the Department on the Taieri Plain is complete, and the Taieri River Trust is carrying out maintenance.

MARINE. Lighthouses. North Cape Lighthouse. —A new flashing-apparatus has been installed in the original lens to take the place of the original flasher, which had not been wholly satisfactory. Matakaoa — This light has been equipped with a new automatic acetylene flashing-apparatus. Cape Maria Van Diemen. —Surveys were made and investigations carried out in regard to the transport arrangements between the landing-stage and the tower, keepers' houses, &c. Owing to the financial stringency the new proposals have not yet been put in hand, but it is hoped to proceed with them early. Measures are also in hand to deal with the drifting sand, which causes considerable inconvenience at this station. East Head.—A site has been selected for this light on East Head,- Akaroa Peninsula, and the necessary flashing-apparatus, lens, and lantern have been ordered. This light, being located on the main salient point of the Peninsula, should be of great assistance to coastal traffic both from north and south. It is proposed to call this "Le Bon Light," after the bay of the same name, which is adjacent. This will avoid any confusion with the existing East Cape Lighthouse in the North Island. Portland Island.—A radio telephone set has been established at this station, which should considerably relieve the isolation and enable the keepers to be in constant communication with the mainland in case of emergencies. Baring Head. —An area of land has been acquired for the new light in this locality, which will take the place of the existing-high-level light at Pencarrow. A contract is being let for the construction of the access road, and it is expected that contracts for the erection of cottages, fog-signal house, tower, &c, will be proceeded with almost immediately. The apparatus will be of a powerful flashing type' and, being erected on this salient point, should be of great assistance to shipmasters. The new light erected by the Harbour Board at the entrance will then take the place of the old Pencarrow Head Lighthouse, which has been in operation for over seventy years. Godley Head. —The necessary apparatus for converting this light from a fixed oil-burner to a flashing type has been ordered, and the conversion should be completed early in the coming summer. Although this light is still thoroughly efficient, the universal use of powerful public and domestic electric lights render the fixed character unsuitable, and it is for this reason that the change is being made. Taiaroa Heads. —A new powerful fog-signal, constructed on the diaphone principle and similar to those already installed at Pencarrow and Godley Head, was installed. It is housed in a reinforcedconcrete building, and is a great improvement on the old explosive signal. Okuri Point. —Repairs have been carried out to the landing-gantry. French Pass.— Some dangerous overhanging rocks which were shattered in the earthquake have been removed, as they were threatening the safety of the station. Brothers.—A contract has been let for a new crane for the north landing, and some of the rocks which were dangerously overhanging the south landing and crane have been removed. The buildings generally on this station are getting old, and a general overhaul will have to be undertaken during this coming year. ...... Kahurangi.—A new 800 mm. lens has been installed in this lighthouse to take the place of the old lens, which was irretrievably damaged by the earthquake, and new cast-iron segments have been erected, some of the original segments having been badly cracked. The light itself is operated automatically, the illuminating-apparatus consisting of a Dalen burner using acetylene gas. Provision is being made this year for the erection of a new keeper's house, the old houses being practically destroyed by the earthquake, and the single keeper there is at present occupying only temporary accommodation.

Harboubs. Westport Harbour.— -Entrance and bar: Conditions generally at the entrance have not been altogether satisfactory, and in spite of continual dredging difficulty has been experienced in maintaining at all times an adequate depth of water for the class of vessels now trading here. As mentioned in my previous report, the only satisfactory method of dealing with these conditions is to extend the training-walls. Work on these lines was proceeded with during the year, but unfortunately the financial conditions of the harbour, due to the reduction in the export of coal, has been such as to necessitate a temporary cessation of the breakwater-construction. The suction dredger " Eileen Ward " has been kept constantly employed on the bar, and has removed a total of 571,885 yards during the period. Lower River : The average working-depth of the river over the period was 24 ft. 3 in., which is a slight reduction over last year's average. The dredger " Maui " was occupied part of her time in this portion of the harbour, principally in the floating-basin and in the vicinity of the Cattle Wharf, and in this area she removed 14,475 cubic yards. Berthage area : With the exception of the work at the Cattle Wharf, the bucket dredger " Maui " has been engaged solely in deepening the berths and improving the river fairway opposite the wharves, and depths generally have been maintained, total yardage shifted by the bucket dredger for the year being 97,570 cubic yards. Eastern Breakwater extension : Prior to the commencement of the work on the Western Breakwater, 604 tons of first-class stone was tipped with a view to consolidating the postion there. Western Breakwater : A definite start was made with the extension of this breakwater, the timber staging being driven and the depositing of stone commenced in July. Considerable difficulty was experienced with heavy weather the first few days while the staging was being erected, and two bays were carried away. 130 ft. of staging has been erected and 22,397 tons of stone have been tipped. This work has, however, now been discontinued, owing to decreased output of coal and consequent shortage, of funds. Quarry : The quarry has been worked regularly throughout the year ; the quality of the stone is good, and it is estimated that there is ample good stone in the vicinity of the present workings to complete the proposed breakwater extensions of 300 ft. A considerable amount of waste material has to be shifted in order to procure the suitable large stone, and this has considerably hampered the output generally. Prior to the suspension of work it had been proposed to procure a small steamshovel to facilitate the loading and disposal of this waste material, and to clean up the quarry-floor generally. This should be one of the first matters to be attended to when work is recommenced, and a new 10-ton crane will have to be purchased or the existing 10-ton machine very thoroughly overhauled. The total output for the year has been 38,980 tons, but this included approximately 16,000 tons of third-class stone, which has been used on the extension of the wall at Organ's Island and the groyne at McPadden's. River-protective works : The training-wall at Organ's Island which was built last year has been extended for about 3 chains, and, although there have been comparatively few floods, the present effect indicates that the river should considerably straighten its course through the shingle-bank between it and Roselli's. The willow plantations near Hannah's are now becoming well established, and where any damage has been caused it has been reinstated. The river-banks where protected with willows resisted the January flood well. Surplus stone from the qxiarry which was not suitable for breakwater-construction has been tipped at McPadden's in continuation of the protective groyne there. Plant: The plant generally has been fully maintained. The suction dredger " Eileen Ward' and the bucket dredger " Maui " have been constantly in use, and wherever possible all necessary repairs and renewals have been carried out when dredging-conditions were unsuitable, in order to keep them thoroughly efficient. The suction dredger " Rubi Seddon " has not worked during the period, but the necessary attention has been given to this vessel in the nature of chipping, tarring, and painting, and the engines are periodically turned over. The tug " Mana" and the launch " Kaiuruanga " have both been slipped, and are in first-class order. The workshops have been kept .busy repairing and maintaining the dredgers, locomotives, trains, &c. ; and signal-station buildings, beacons, lights, &c., are in good order. Karamea Harbour. —Fairway and entrance : During the year the shoaling in the fairway has .been accentuated. An enormous quantity of sand, silt, and general detritus has been brought down jfco.the lower reaches by successive floods in the Karamea River, and a very considerable deposition has occurred in the slacker waters through the coastal plain. The last investigation of the upper reaches of the river, in January, confirmed the extensive rending and disturbance of the hills and mountains ..by the earthquake in nearly all parts of the watershed, and revealed the fact that only a comparatively small quantity of the disintegrated rock-material had reached the tidal area. The transportation of detritus, associated with deposition in the lower reaches and harbour area, can be confidently assumed for many years to come, and under these circumstances any marked immediate improvement in the harbour entrance and fairway with works in hand or proposed can hardly be anticipated, though the influence of such works in relation to the river-flow is an important factor. At the beginning of the period under review it was possible to work the port only at spring tides and with favourable sea conditions. A slight improvement to the channel at the wharf occurred in October, but further floods practically closed the port to shipping as from November, 1930. The last serious floods, which occurred at Easter (3rd April, 1931), caused further extensive deposition and the formation of shoals between the Otumahana and the training-wall, and resulted in a considerably increased flow (approximately 70 per cent, of the river) down the Otumahana Channel. Steps were immediately taken with regard to a proposal for improving the flow over the Karamea bar by

48

D.—l

blocking the entrance to the Otumahana with a half-tide pile and netting wall. This work to influence and regulate the Karamea River flow is now in hand. Work carried out during the year to reduce the Otumahana overflow with a blockage of logs and cable was effective up to the time of the Easter flood. Training-wall: During the year the work of replacing the old timber-pile wall by quarried stone has been expeditiously carried out, 11,803 tons of stone having been placed during the year. Further temporary strengthening and retopping of the old wall was necessary for stone-tipping purposes. The whole length of the wall (17| chains) has been completed to half-tide level, while at the extreme outer end a length of 5 chains has been built as a full-tide wall. At a point near the approach bank of the training-wall 300 tons of ballast was tipped for use in extending the stop-bank round the adjacent length of Simpson's Island to prevent flooding of the tram-line during spring tides. Oparara Quarry : At the beginning of the year a new quarry was being opened up. This has developed very satisfactorily and produced excellent stone. Various tunnels for quarrying the rock have been driven and fired with good results. During Christmas and New Year holidays the quarry plant and rolling-stock were thoroughly overhauled. At Rhind's erosion protective works, adjacent to and associated with the quarry, 833 tons of box stone and spoil have been placed. Survey : A comprehensive survey has been made to definitely establish relative information concerning the harbour and adjacent areas for future reference and for the consideration of various proposals at present under review. Little Wanganui Harbour. —Since the closing of the Karamea Harbour the Little Wanganui Harbour has been worked on an average of once a week. The " Kotiti " can reach the wharf at high tide at all times, while the " Fairburn " arranges her itinerary so as to call at spring tides. Towards the end of the year, a sandspit commenced to encroach on the up-stream end of the wharf and threatened to interfere with the berthage. This was partly due to the influence of a huge earthquake slip a short distance up the river. Proposals have been approved for the erection of a piled permeable groyne to regulate the channel-flow so as to give the desired berthage-improvement. Waikokopu. —During the year work has been continued on the breakwater, except during the period when the contract was under revision. About 9,000 tons of stone were deposited in place, and, even though the wall is yet unfinished, the benefit to the wharf is very apparent, the shelter being very much improved. This locality is subject to very sudden storms, and as an indication of this it may be mentioned that the breakwater staging was wrecked by storms twice during the year. It is anticipated that this work will be completed in about six months' time. A transmission-line has been put in and the wharf-lighting connected up with the Power Board's electric mains. The wharf and wharf facilities have been well maintained, and the trade has been very constant throughout the year. Tairua Wharf. —A new wharf was erected at the end of the existing jetty in place of the old wharf, which had collapsed. The new wharf has a kauri superstructure on turpentine piles. Matiotitawa Wharf. —The approaches to this wharf were completed during the year. Naumai Wharf. —The approach to this wharf was also completed during the year. Tikinui Wharf. —Plans were prepared for the construction of a new wharf, 118 ft. long, with approaches, and the work has been put in hand. Tinopai Wharf. —This wharf has been completed, together with approaches. General.

IREIGATION—CENTRAL OTAGO. Operation or Completed Irrigation Schemes. During the past year the several completed schemes have been maintained in good condition, and all lands requiring water have been supplied. The irrigation season was a fairly successful one, the water-supplies have been good, and the distribution of water has been subject to very little interruption. Of the schemes in operation, the following are on a trading basis : Ardgour, Bengerburn, Earnscleugh, Galloway, Hawkdun, Ida Valley, Last Chance, Manuherikia, Tarras, and Teviot. Accounts have been rendered for £14,120, and working-expenses amount to £14,152, or very nearly the same as the amount of the accounts as rendered. This does not show a return as well as last year, the reason being that the Hawkdun scheme has now been included on a trading basis where irrigators are paying on the earlier (lower) stages of the deferred scale ; and on two other schemes substantial areas have been withdrawn for the time being from irrigation. The number of irrigators in the total area irrigated on all Government schemes for the past year is as set out in the following table :—■

For the previous year the totals were 395 irrigators, with 41,895 acres under irrigation. Of these schemes, the Arrow scheme, which is now complete, has come into partial service. Some settlers have used little or no water, this being largely due to the wet summer experienced. At Galloway the temporary pumping-plant continued in use during the season to ease the draw-ofi from Mahorburn reservoir, but the need for its further use no longer exists, and it has been dismantled. At Ida Valley, a diminished supply was again given this year, on the same scale as indicated in my last year's report. Storage is now accumulating in the new Poolburn reservoir, and as Manorburn reservoir is now accumulating a much better storage than in the preceding two years the full supply will be given next season. The position in respect to the payment of last season's irrigation accounts is very serious, the greater amount being outstanding, although the time up to which rebate is allowed has lapsed. The matter requires the serious consideration of the Government. New Schemes and Additions to Schemes in operation. Poolburn Dam, Ida Valley Scheme. —This work, designed to supplement the storage necessary for the Ida Valley scheme, is now complete. Concreting recommenced, after the winter shut-down, on the 3rd November, 1930, and finished on the 22nd May last. The whole construction operations ran very satisfactorily, the plant layout was very suitable, and an excellent job has resulted. Quantity of concrete in this work is 13,980 cubic yards. Idaburn Scheme. —This small scheme, located at Oturehua, will supply water to 600 acres, distributed among eight settlers who have signed agreements. Work is proceeding on the excavations of the foundations for the dam, and some race-work has been put in hand. SUBVEYS AND INVESTIGATIONS. Lauder-Omakau Scheme (Upper Manuherikia). —Under this scheme 14,000 acres of irrigable land are included. Surveys and plans of the various works necessary are complete. The land under this scheme is favourably situated as an irrigation project. No steps have yet been taken to have irrigation agreements signed. Maniototo Scheme. —A survey party has now been in the field for two months, running contours, taking levels and cross-sections to enable a preliminary decision to be made regarding major works, and the most suitable area or areas for irrigation development. This scheme covers a very large area-— over 100,000 acres —very favourably situated, both as to aspect and easy slopes, for irrigation purposes, and as to roads and railways for the transport of the produce which will be grown when the land is irrigated.

TRAMWAYS. Auckland. —During the year the Auckland Transport Board has carried on a progressive policy in regard to new construction, the following works being carried out and approved : Mount Eden Road, 173-26 ch. double track ; Sandringham Road, 64-50 ch. double track ; Richmond Road, 105 ch. double track ; Station Loop, 25-50 ch. single track ; Garnet Road, 58 ch. single track. Inspections and brake-tests were made for seventeen new tram-cars. New Plymouth. —Three cars were converted to one-man control, and fitted with compressed-air emergency, service, and rheostatic brakes, and automatically air-operated folding doors. These were inspected and passed. Wanganui. —-Four cars have been reconditioned and arranged for one-man control, being fitted with compressed-air emergency, service, and rheostatic brakes, and have been tested and approved. Wellington. —The following new works were carried out and approved : Aro Street extension, 3-4 ch. ; Whitmore Street extension, 10-5 ch. double track ; Customhouse Quay realignment, 26-36 ch. ; Grosvenor Terrace, 41-1 ch. duplication ; Hobart Street, Miramar, 28-9 ch. duplication. Five new cars were tested and passed for service. Christohurch. —No new lines were laid during the year, but re-laying of existing lines was carried out between Carlyle and Brougham Streets on the Cashmere Hills route, between Leinster Road and Papanui on the Papanui route, and between Fitzgerald Avenue and Bamford Street on the Sumner line. An alteration to the lines in the vicinity of the Avon River Bridge, on the New Brighton line, was effected, this being necessitated by the construction of the new bridge. Authority was granted the Tramway Board to discontinue the tram service between Papanui and the old terminus at Northcote Road. The tram-line has been taken up and the tram service has been replaced by a petrol-bus service. The institution of a trolly-bus service to serve North Beach was well forward; this service actually commenced to run on the 4th July. No new tram-cars were put into operation during the year, but seven forty-passenger trolly-buses have been constructed and were ready to be placed in operation by the 30th June.

STAFF. I would like to place on record the exceptionally good work which has been done by the staff during the past year. The numbers of men employed rose to a figure unprecedented in the history of the Department. Officers were called upon at short notice to commence works for the relief of unemployment, and responded splendidly. Had the numbers not fallen considerably later on, it would have been quite impossible to continue without very considerable increase in the staff, as many of the officers were really strained to the breaking-point, but nevertheless carried on. I would particularly like to mention the staff in the Hawke's Bay District, who stood up to the shock and immediately commenced remedial measures and the organizing of relief in a way which invoked the admiration of all with whom they came in contact.

PUBLIC BUILDINGS.—MAINTENANCE. The maintenance of public buildings has been carried out by the District Engineers and their staffs in accordance with proposals and reports prepared in District Offices. Maintenance work is, for more ready reference, included with public-building work reported on by the Government Architect.

PUBLIC-BUILDING WORKS AND ELECTRICAL OPERATIONS.

APPENDIX C.

ANNUAL REPORT OF 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 Department for the year ended 30th June, 1931. During the period plans were prepared for forty-one new works, of a total estimated value of £329,460, of which sixteen contracts, to the amount of £56,250, have been let. In addition, thirty contracts, to the amount of £188,801, for buildings designed prior to the 30th June, 1930, have also been let, making the total works completed or under construction £245,455. The latter total includes £73,126 for secondary-school buildings. 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 showing a downward tendency, and the standard of workmanship has been satisfactory. Earthquake.— The Hawke's Bay earthquake of the 3rd February subjected buildings to an exceedingly severe test, which Government buildings, generally, on account of their more substantial construction, withstood remarkably well, there being no cases of collapse other than the clock-towers of Hastings and Wairoa Post-offices, and no reported injury to persons except those resulting from the falling of the Hastings tower. The Post and Telegraph Department, to obviate this danger, has for several years discontinued the practice of building clock-towers. The departmental building at Napier and Port Ahuriri Post-office were totally destroyed by the combined effect of earthquake and fire. The new post-office at Napier successfully withstood the shock without structural damage, but was completely gutted by fire. All modern brick buildings and additions erected by the Government in the area embodied earthquake protection (uncalculable), and some came through the ordeal unscathed, others with minor damage only, while some show large cracks and extensive damage, which serve to prove that Government buildings were not, as has been repeatedly stated, unnecessarily strong, and that comparatively little more earthquake protection would have been sufficient. In view of the lesson learned in Hawke's Bay, steps are being taken to provide additional stiffening in existing buildings where such is deemed necessary. In recent years all State buildings of over three stories in height have been designed with steel frames definitely stiffened to withstand the horizontal forces of a very severe earthquake. The following is a schedule of works carried out during the year:— Viceregal Residences. Auckland. —lmprovements were carried out to the kitchen, including tiling-in of the large gas range. General maintenance was also carried out during the year. Wellington. —General maintenance was carried out during the year.

APPENDIX D.

ANNUAL REPORT OF THE CHIEF ELECTRICAL ENGINEER.

The Chief Electrical Engineer to the Hon. 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, 1931, represents the sixteenth year of operation of the Lake Coleridge undertaking, and the year's working again shows satisfactory results under exceptional conditions as outlined elsewhere in this report. Financial. The capital outlay at the end of the year was £1,712,555, as against £1,622,199 for the previous year, showing an increase of £90,356. The total revenue for the year was £217,632 as compared with £196,648 for the year ending 31st March, 1930, and after payment of all charges, including interest and depreciation, the net profit was £70,083, which has been allocated as follows : £17,126 to Sinking Fund, and £52,957 to General Reserve Fund. Table I shows particulars of financial results and load records, while Table II gives an analysis of capital outlay for the years 1930 and 1931. The total cost per unit generated and purchased was 0-29 d., an increase of 0-04 d. on that of the previous year, the increase being due to decreased unit output in conjunction with increased workingcosts. Operating-costs have increased by £20,225, due chiefly to a payment of £21,170 towards the purchase of power. The latter amount, however, does not include a total payment of £1,674 13s. 9d. by way of rebate to supply authorities. Details of operating-costs are shown in Table 111. Connected Load. The total connected load at the end of the year was 200,535 kw., being an increase of 10-2 per cent, over the previous year's figures of 181,310 kw. Restricted Supply. Owing to the shortage of water at Lake Coleridge, a general appeal was circulated on the 26th August, 1930, amongst the supply authorities to institute a campaign of economy in the use of electricity. The Tramway Board's stand-by plant was called in on the 26th August to render assistance. As the first appeal was apparently not taken seriously, a second circular was sent out on the 4th September, and immediate results were noticed in the power-house load and the level of the lake. I take this opportunity of placing on record the valuable assistance rendered by both private consumers and supply authorities, and desire to express my sincere thanks for and appreciation of their efforts to help the Department. Acheron Diversion. Owing to lack of water in. the lake, it was decided to divert the Acheron River, and this was successfully done in December, 1930. Power-house Load and Operation. The maximum half-hourly output from the power-house for the year was 30,800 kw. on 9th June, representing an increase of 11-8 per cent, over that of the previous year, the increase being of normal character. The annual load-factor was 44-8 per cent., which is a decrease of 13-18 per cent, on that of the previous year. The power-house plant was not overloaded as the installed capacity of the plant is 34,500 kw., and the maximum demand only 30,800 kw., the power-factor being 0-97. During the period Ist April to 30th June, 1931, the maximum half-hourly load at the powerhouse was 30,340 kw. on Tuesday, 23rd June, between 4.30 p.m. and 5 p.m., the power-factor being 0-975. This load is 460 kw. less than the recorded load of 30,800 kw., which was observed on 9th June, 1930. The maximum number of units generated in any one day was 453,710 on the 6th June, 1930, as against 419,420 units on 19th June, 1931.

Lyttelton Diesel Station. After careful consideration was given to the suitability of several sites for the installation of a Diesel electric-power station, the location at Lyttelton was finally selected in the first week of November, 1930, and excavation was immediately started for the foundations of the units and the building. A high rate of progress has been maintained throughout construction by the General Branch of the Public Works Department. The first two of the four engines to be installed in the first stage of construction of this station were landed on the 3rd February, and erection of all equipment and accessories was pushed on with all speed in case of another shortage of water at the lake. A trial run of No. 2 unit was carried out on the 4th June. Survey and Easements. The following surveys were carried out during the year : Acheron River diversion, completion of Waitaki power-supply and Glenavy steel-tower line, second Timaru-Oamaru line, preliminary work in connection with the Oamaru-Dunedin line, location of site for Lyttelton Diesel station, and route of 11 kv. Lyttelton-Woolston line, steel tower crossing over the Waimakariri, location work at Timaru, Oamaru, and Glenavy substations. Negotiations with reference to easements covering the above routes were undertaken satisfactorily. Live-line Operation. Further progress has been carried out in this section with consequent reduction in interruptions to consumers. All insulators on the 11 kv. feeders were tested. Twenty-six poles were replaced under live-line conditions. The 33 kv. transmission-line to Banks Peninsula Power Board was overhauled, and all the 66 kv. insulators were tested between Lake Coleridge, Addington, and Timaru. Live-line methods were utilized in the installation of a 5,300 kv.a. transformer-bank at Oamaru Substation, thereby reducing the total period of interruption of supply to a few minutes. During the year a live-line cleaning-appliance was developed and tried out with satisfactory results on 66 kv. and 110 kv. insulators while alive. Transmission-lines. Owing to the absence of gales and heavy snowfalls, in the systematic cleaning and testing the line-insulators under live-line conditions, and cutting of trees likely to prove dangerous, very little line trouble was experienced during the year. Headworks and Power-house. Full opportunity was taken of the extremely low level of the lake to remove accumulations of shingle. To prevent the tendency for the water to shoal in the vicinity of No. 1 intake cylinder the original groyne was shortened by about 12 ft. and encased in concrete throughout its length. The western groyne was also concreted over the greater part of its length. No. 1 tunnel was inspected from end to end and found in very fair order. No. 2 tunnel was also partly drained for cleaning the screens at the intake, inspection of the cross-drive tunnel, and of the lake end of the tunnel. No. 3 and No. 6 lines have been painted. The annual report for year ending 1930 stated that seven out of the ten E.H.T. 4,000 kv.a. transformers had their low-tension coils replaced. The remaining three were dealt with this year. The reorganized lay-out of the whole of the 66 kv. equipment, which was commenced last year, has been completed, with the exception of the control wiring for the main oil circuit-breakers. Professor Hornell paid an unofficial visit to the power-house, lake, and headworks in October, 1930. Addington Substation. A 12,000 kv.a. bank of 66/11 kv. transformers which arrived in February was erected in March. The capacity of this substation will accordingly be increased from 29,000 kv.a. to 36,000 kv.a. A new circulating water-pump has been installed. A comprehensive lay-out of railway sidings was prepared and the first section to deal with equipment to and from the substation building itself was laid. Tests of the bearing value of the ground on the sites of the proposed test laboratory and steel structure were taken. No damage to any equipment was observed due to the severe earthquake of February last. No. 2 synchronous condenser, with a capacity of 10,000 kv.a. has arrived, and will be erected as soon as the construction on the two-bay extension of the substation building has been sufficiently advanced. Point Substation. The stick-operated single-phase isolating-switches have been replaced with triple-pole isolators. HORORATA. The whole system of earthing has been rearranged. Alterations involving increasing the number of 0.C.8.s from four to eight, replacing the stick-operated isolating-switches with gang-operated type, and replacing the independent-operated earthing-devices with a simpler method of grounding the lines was commenced in February. Ashburton. No structural alterations were carried out at this substation during the year.

TIMARU. The contract for the removal of the two staff cottages was let in February, and one of the cottages was re-erected in its new location in March. The first portion of the new steel structure and switchgear for the auto transformers has arrived, and the transformers were erected in October. The overhead reticulation likely to interfere with the erection of the steel structure was deviated. 0 AMARU. Owing to this station being overloaded, its capacity was increased from 1,Q50 kv.a. to 5,300 kv.a., by replacing two banks of transformers of 300 kv.a. and 750 kv.a. capacity respectively with a single bank which had been converted from an indoor water-cooled type to an outdoor air-cooled type. The above 5,300 kv.a. transformer-bank has been erected in its permanent position in relation to the steel structure, but a temporary line has been installed to connect it with the existing arrangement. During the year alterations to the electrical layout in the switch-house were carried out. Interruptions to Supply. (a) Power-house Supply. There was only one interruption of 5| minutes, which involved an outage throughout the whole undertaking. (b) Addington, Point, and Hororata Supply. The total number of interruptions to supply exceeding one minute throughout the year was three, and the accumulative period was 11 J minutes, the longest interruption being 5 J on the 24th July. None of the above interruptions was due to insulator-failure, the systematic testing, cleaning, and weeding-out of defective insulators under live-line methods probably being chiefly responsible for this satisfactory condition of transmission of supply. (c) Ashburton Supply. The total number of outages was four, excluding those that had been prearranged, and the total period was 16 minutes. (d) Timaru Supply. The total number of interruptions for the year was nine, and the total time 55| minutes, as against twenty-one interruptions with a total time of 2 hours and 54 minutes for the previous year. (e) Oamaru Supply. Excluding all shutdowns that had been prearranged, the number of outages for the year was fifteen, and the total period 6 hours 53| minutes. Distribution. Tenders for the tower-foundations for the Waimakariri Eiver crossing were invited in December, and pile-driving was commenced in March. The telephone circuits on the north, south, and Lyttelton 11 kv. feeders were overhauled and the No. 8 galvanized-iron wire of which the circuits consisted were replaced with No. 10 cadmium copper. The 7/12 aluminium conductors on the 11 kv. Montreal 1 and 2 and tramway 1 and 2 feeders were replaced with 7/0-135" aluminium cables which had been previously removed from the 66 kv. lines. Hanmer Power-supply. On behalf of the Health Department, alterations were made to the Hanmer Power-house. _ A new Diesel electric set was installed to replace the petrol electric set, thereby increasing the capacity of the station from 45 kw. to 55 kw. Eelay Protection. Preparations have been made for the installation of new relay panels at Lake Coleridge Power-house, Addington, Woolston, and Lyttelton Diesel stations. General. A sectionalized type of drying-oven was designed and manufactured locally during the year. For some considerable period the Testing Department has been functioning at a great disadvantage. The small poilite outbuilding is quite inadequate for the staff, equipment for carrying out tests, and tests records. A design for a new building has been prepared to house the test laboratory, the distribution office and workshop, the E.H.T. testing equipment, transmission-line and distributionline stores, and live-line-testing equipment. The present store at Addington is to be removed before the outdoor steel structures and switch-gear can be erected. A design was prepared for a combined Public Works Department store to serve the requirements of the General and Hydro-electric Branches. A railway siding will be laid alongside this store, and will remove a serious handicap which has had to be contended with hitherto. The railway sidings for the substation building, the test-room, the store, and the outdoor steel structure have been laid out as a single comprehensive scheme for efficient and economical transport of all equipment to and from the substation. The line for the Hurunui Power Board will be surveyed and constructed in the near future, and the substation at Southbrook will be at the same time redesigned.

At present Stoddart's Corner Substation chiefly supplies Banks Peninsula Power Board through a step-up 11/33 kv. transformer-bank. A route for a 33 kv. transmission-line will be determined and its erection between Addington and Stoddart's Corner will be proceeded with in due course. At various river-crossings anti-vibration jumpers were fitted to the A.C.S.R. conductors to prevent the breakage of the strands at the clamps due to crystalization caused by vibration of cables between line-supports. Lake-level and Rainfall. The year has proved exceptionally dry, and the lowering of the level of the lake has caused much anxiety to both .this Department and supply authorities and their consumers. In 1929 the average rainfall over the lake area was 41-89 in., whereas in 1930 it was 25-18 in. The lowest level of the lake was recorded as being 1,658-5 ft., and in March the maximum height of 1,667-55 ft. above sea-level was registered after drought conditions. The level of 1,658-5 ft. represents a drop of 13-5 ft. below the normal lake level of 1,672 ft. The rainfall at the power-house for the calendar year 1930 was only 22-05 in., the lowest on record, as against 36-28 in. for the previous year : 6-80 in., out of the total of 22-05 in., fell in January when the lake was at overflow level. Tai Tapu Dairy Co. I have to report that amicable arrangements have been arrived at whereby this company, one of the oldest consumers of power from the Lake Coleridge scheme, will on Ist July, 1931, hand over its functions as a supply authority to the Springs-EUesmere Power Board. HORAHORA - ARAPUNI ELECTRIC - POWER SUPPLY. 1. Capital Outlay. The total capital outlay at the end of the year, as shown in Table X herewith, was £3,939,122, an increase during the year of £278,695. The main items of increase were £49.336 on headworks at Arapuni, £44,494 on the generating-station, transformers, and other machinery, which includes part of the cost of No. 4 unit, £47,544 on remedial works at Arapuni, and £106,754 in interest during construction — i.e., approximately ten months' interest on works not in operation. The value of assets in operation at the end of the year (Table IX) was £1,286,667, as compared with £3,330,011 and £1,142,346 for the two previous years, the drop in the one year of over £2,000,000 being due to the closing-down of Arapuni and those other parts of the system which are not at present required to deal with the smaller amount of power now being sold. 2. Financial Results of Operation, and Future Prospects. The gross profit for the year — i.e., total revenue, £184,593, less working-costs, £101,889 —was £82,704. Working-costs includes an assessed amount of £20,737 to be paid to the Auckland Power Board as part compensation for the use of King's Wharf plant as a standby, so that the gross profit on actual supply of power by the Department was £103,441, or 5-99 per cent, on the average capital outlay. Interest and depreciation charges for the year amount to £118,398, so that the loss on the year's working was £35,694, inclusive of the payment mentioned, and £14,957 without including that payment. The corresponding loss the previous year was £32,768. Operating or working-costs are analysed for the past four years in Table XI herewith, and show the following points : Increase in total operating-costs, principally due to increased use of the fuelplants and increase in standby provision. Increase in operating-costs at Horohora, due largely to increase in amount of screen-cleaning necessary to get the full output from the plant. Increase in transmission-line and substation operating-costs in 1929-30, due to the increased mileage of lines and additional substations brought into operation at about the same time as Arapuni. 3. Extensions during the Year, and Future Extensions. (a) General, Additional Consumers, and Connected Load. There were no additional consumers during the year. The connected load, not including Auckland electric - power district, has increased from 89,523 kw. to 99,341 kw. The number of milking-machines supplied has increased from 4,988 to 5,493, electric ranges from 2,807 to 3,420, and water-heaters from 7,088 to 8,229. These are exclusive of Auckland Power Board figures. The system maximum-load figures for the past three years are 15,900 kw., 41,520 kw., and for this year 49,520 kw., when Arapuni was supplying, and 17,600 kw. since that time. The demand factor (not including Auckland) was 17-7 per cent. (b) Power-stations. Arapuni. —The erection, of the three units comprising the initial installation had been completed the previous year, and the erection of cable-work and switch-gear for No. 4 unit was in progress at the end of this year. No. 4 turbine and generator arrived, and were stored at Putaruru Station-yard.

(a) Transmission-lines. The Waihou-Paeroa 50 kv. line and switching-structure at Paeroa were completed early in the year. Survey of New Lines. —New 110 kv. lines are being surveyed as follow :— Arapuni-Edgecumbe-Murupara portion of the Arapuni-Waikaremoana Line : Survey practically complete, and pegging of pole positions to Edgecunibe commenced. Arapuni-Penrose Second Steel-tower Line: Work of contouring angle positions was carried out. Henderson - North Auckland: Detailed survey of both power and telephone line are now practically complete. Arapuni-Stratford : The survey of the selected route was practically completed, and plans prepared for location of pole-positions. A good deal of work is still to be done in investigating foundations in papa country. Poles and wire have been ordered for construction of part of this line. (d) Substations. Penrose (110/22 kv.—60,000 kv.a. capacity; 22/50 kv.—5,000 kv.a. capacity).—The installation of capacitors and protective relays for the three incoming 110 kv. lines was completed. Three additional switch-gear panels arrived, and erection of them was commenced. The Power Board's cable to No. 4 panel was connected up in November, 1930. Tahapuna (50/11 kv.—2,000 kv.a.). —New bank of transformers (four 750 kv.a. single phase) arrived, and transported to the substation. Waihou (50/11 kv.—2,250 kv.a.). —The 50 kv. transformer 0.C.8. was installed, also the turntable, completing the present installation. A house was built for the operator. Hamilton (50/11 kv. —3,000 kv.a.). —The motor-generator set for battery-charging and the control panels for No. 2 Substation were erected. The control cables to No. 2 Substation were laid underground. Bombay (110/50 kv. —5,000 kv.a. ; 50/11 kv. —3,000 kv.a.). —Two new feeder cubicles were installed by the Franklin Power Board. A second bank of transformers (three 500 kv.a.) arrived, and were put in service on 23rd December, 1930. (e) Huntly Power-station. One 1,500 kw. steam turbine, 3,000 r.p.m., 550 volts; three 623 kv.a. transformers, 550/11,000 volts. On the failure of Arapuni in June, 1930, it was decided to remove the above turbine-set from the Grand Junction plant at Waihi, and re-erect it at Huntly. The turbine was run up to speed on 27th March, 1931, and operated very satisfactorily. 4. Operation and Maintenance. (a) Power-stations. Hordhora. — This station operated satisfactorily throughout the year and the usual routine maintenance repairs were effected as opportunity offered. Arapuni. —The failure of the headrace at Arapuni, which resulted in the closing-down of the power-station on 11th June last, was dealt with in the last annual report. Since then the power-house machinery and apparatus has been maintained in good order by the use of electric heaters and calcium chloride where necessary to ensure dryness. Penrose Diesel Plant. —The plant has operated successfully during the year. The new spray pond in conjunction with the cooling-tower, enabled all three engines to be run for long periods without excessive cooling-water temperatures, supplying load up to 3,980 kw. maximum, with weekly output up to 320,000 units. Grand. Junction Steam Plant. —This plant ran satisfactorily during the year, and carried up to 3,000 kw. load in June, 1930, after the failure of Arapuni. After September, 1930, only the 1,640 kw. unit was available to supply power. (b) Transmission-lines. 110 kv. Lines. —Further work was done during the early part of the year in improving towerfoundations in clay country. There were no outages due to line-faults during the year. 50 kv. Lines. —There were only four cases during the year of failure of insulators in service causing interruption, all of these being on the old Horahora-Waikino line, three being pin insulators and one a strain insulator string. Bombay-Kerepeehi-Waikino Line : A big improvement in telephone operation on this line was effected by rearranging the transpositions to get better balance. Horahora- Matamata-Waikino: The dismantling of the Half-way-No. 8 hut portion-of this line was completed early in the year. Ngongotaha- Edgecumbe- Waiotahi: On 2| miles of this line near Tikitere, 7/14 S.W.G. copper wire, which was being affected by sulphur fumes, was replaced with 7/13 S.W.G. galvanized iron, painted with sulphur-resisting paint. Inspection of a length of one mile, which had been previously dealt with in this way, showed that the wire was in good condition. (c) Substations (Sixteen). Penrose, Matamata, Waihou, Waikino, Huntly, Bombay, Waiotahi, Henderson, Takapuna, Hamilton, Te Awamutu, Hangatiki, Kerepeehi, Mamaku, Ngongotaha, and Edgecumbe: Nothing of importance to report.

(d) 11,000-v. Lines and Substations. A total of forty-one 35 ft. poles have been found defective on these lines, and have been replaced during the year. Service generally has been good. (e) Power purchased and generated by Stand-by Plants, System Operation, and General. Power purchased (£9,271) during the year totalled 8,226,397 units, or 5-7 per cent, of the total system output of 143,093,777 units. The greater part of the power purchased, 7,444,500 units, was obtained from McLaren's Falls. MANGAHAO - WAIKAREMOANA ELECTRIC - POWER SUPPLY. I. Financial Results. At the close of the year 1930-31 the capital outlay amounted to £3,498,840. The net revenue for the year was £283,017, and working-expenses £59,476. After paying interest, totalling £196,206, a net surplus of £27,335 was shown. Depreciation charges amount to £63,850, which leaves a deficiency on the year's working of £36,515. The financial results and load records are analysed in Table V, whilst Tables VI and VII give an analysis of the capital outlay and working-expenses. The gross financial results of the system are given in Table VIII. The earthquake on the 3rd February, 1931, was responsible for a direct loss of revenue of £3,576, and, in addition, it was necessary to purchase power from Wellington City Council and other supply authorities, costing in all £4,441. The total effect of the earthquake on the revenue was, therefore a loss of £8,017. The general depression throughout the country also reduced the revenue during the vear bv about £8,000. * 11. Operation and Maintenance. Mangahao Power-house and Headwords. —The various items under this head operated very satis factorily during the year. The generators and turbines have operated well, practically the only trouble met with being chipped, cracked, and spongy buckets on the turbines. At no time during the year was a unit under repair when in demand. Tail-race : Very little maintenance has been necessary during the year, the channel now appearing to have become stable. Waikaremoana Power-house and Headwords. —All apparatus has functioned satisfactorily except for the burning-out of four coils of No. 2 generator, which caused this unit to be shut down for fourteen days for repairs. All damage caused by the earthquake has been repaired. Substations. KhandaUah. —From this substation power is supplied to Wellington City Council, Hutt Valley Electric-power Board, New Zealand Railways Department, and Wellington Meat Export Co., Ltd. During the year there were seven total interruptions, totalling 12| minutes, to service at this station, none being prearranged. Bunnythorpe.— From this substation power is supplied to the Manawatu-Oroua Power Board. Interruptions to supply during the year numbered ten, of a total duration of 1 hour 2 minutes, apart from four prearranged shutdowns. Due to fire last year destroying all control-gear, &c, this substation has been merely a switchingstation during the year. The metering has been done by the Manawatu-Oroua Power Board's instruments in their substation. All H.T. switch-gear has operated well, as also have the transformers. Marton. —This station, as well as Wanganui, supplies power to the Wanganui-Rangitikei Power Board, the two being normally paralleled on the 11 kv. side. The only fault which developed during the year was the burning-out of a coil on the autoreclosing gear of the 11 kv. feeder-switch. Wanganui.—All apparatus operated satisfactorily during the year. Interruptions to service totalled nineteen, of a duration of 1 hour 24| minutes. Masterton. —This station supplied power during the year to the Wairarapa Power Board. All apparatus functioned well during the year. Interruptions to service (other than those prearranged) numbered twenty-two, of a total duration of 4 hours 45 minutes. Mangamaire. —This substation supplied power throughout the year to the Tararua Power Board, and all apparatus functioned satisfactorily, except for the failure of a H.T. bushing on the 110 kv. 0.C.8., which caused an interruption to service for 17 minutes. Woodville. —As listed under construction, this switching-station has been extended during the year. All apparatus has operated well throughout the year, except for the failure of a rotating insulator (hollow type) of an air-break switch. DannevirJce.— At this substation, which feeds the Dannevirke Power Board, all apparatus functioned satisfactorily throughout the year, no interruptions being caused by faults in the equipment.

68

D.—l.

Service interruptions (other than those prearranged) numbered fifteen, and amounted to 2 hours minutes. Waipukurau. —This substation has supplied power to the Central Hawke's Bay Power Board throughout the year, and all apparatus has functioned well, except during the earthquake on 3rd February, 1931, which caused slight damage, putting the station out of commission for 1 hour 39 minutes while repairs were effected. The damage sustained is mentioned more fully under the report on the earthquake. There were thirteen accidental interruptions to service, totalling 2 hours 3J minutes. Napier. —Hawke's Bay Power Board has derived its supply of electrical energy from this substation throughout the year. This year has been a marked one, owing to the disastroiis earthquake which visited the locality on the 3rd February, 1931, practically wrecking the station. Details of damage done are set out in the report on the earthquake, which caused an interruption to service for 31 hours 5 minutes, power then being resumed at 11 kv. from Waipukurau and Tuai until a temporary substation was erected at Waiohiki. Apart from this, there were thirty-one other accidental interruptions to service, totalling 16 hours 45J minutes. Wairoa. —-This substation during the year supplied power to Wairoa Power Board, and, in general, all apparatus functioned well. The accidental outages numbered twenty-four, of 33 hours 29J minutes duration. The earthquake on the 3rd February was responsible for an interruption to service for 24 hours 32 minutes while repairs were effected. Gisborne. —At this substation, which feeds the Poverty Bay Power Board, the equipment operated well during the year. The earthquake of the 3rd February was responsible for an interruption to service lasting 9 hours 51 minutes. Other accidental interruptions numbered twenty-six, of a total duration of 23 hours 50 minutes. All earthquake damage has now been repaired. Substations : General. At all substations all insulators and bushings on bus-bars and switch-gear were cleaned during the year. Periodical checks were made on all switch-gear, relays, and metering-equipment, and repairs and adjustment made where necessary. The synchronous condensers at Khandallah, Mangamaire, Dannevirke, and Napier were run, when required, for voltage regulation. Transmission-lines (110,000 Volt). Mangaore-Khaniallah Duplicate Line. —During the year there were five outages, totalling 11 minutes, on this line. Three of these, totalling 5 minutes, were due to bird deposits on insulators ; one of 3 minutes to earth-wire, which was being removed from the line, coming in contact with the live line ; and one of 3 minutes to a farmer's wire-ropeway for transporting timber coming in contact with the line. Mangaore-Bunnythorpe Duplicate Line. —This line gave no trouble whatever during the year. The strengthening and replacing of weak poles has been completed during the year from Mangaore to Manawatu River, this section being thoroughly overhauled. The reconstruction of the telephone-line in cadmium copper is in hand, and about ten miles have been wired to the 31st March, 1931. Vibration-dampers were fitted to the cables on the towers at Manawatu River crossing. Bunnyihorpe-Marton-W anganui Line. —This line gave very good service during the year. Sap-testing has been carried out on this line with a view to pole-strengthening being started in the near future. Bunnythorpe-W oodville Line. —This line gave very good service during the year. In connection with the vibration troubles previously experienced on the aluminium cables, vibration-dampers have been installed at various points on the line. All towers were carefully examined for any damage due to the earthquake, but none was recorded. Woodville-Mangamaire-Masterton Line. —No interruptions during the year were attributable to this line, which gave good service. Further excessive wear during the year on the U-bolts on the Mount Bruce towers, and these were replaced where necessary. Woodville-Dannevirke Line. —This line has generally given good service during the year, but a further break on the aluminium jumper at a strain pole has occurred, due to vibration. Vibration-dampers have also been installed on this line on the section where vibration has been responsible for broken cables in the past. Dannevirke-Waipukurau Line. —One interruption to service was caused by this line, a strain-pole jumper breaking, due to vibration. Waipukurau-Napier Line. —-This line gave very good service during the year. Practically no serious damage was done by the earthquake on the 3rd February, but a fair amount of work was necessary straightening cross-arms and replacing weights which had shaken off. The telephone-line also was damaged very little, but the wires were twisted together, making communication over the line entirely out of the question. The damage done was quickly repaired, and the lines made ready for service, power being supplied at 11 kv. from Waipukurau to Napier until the Napier-Tuai lines were repaired.

69

D,—l.

Napier-Tuai Duplicate Line. —This line gave good service during the year, except for the damage sustained in the earthquake on the 3rd February, which is reported more fully elsewhere. A further interruption was caused by an earthquake on the 13th February, which shook open the isolating-switches. Transmission-lines (50,000 Volt). Tuai-Qisborne Line. —Considerable trouble has been experienced on this line during the year in heavy gales, by failure of insulators and pins, and by the telephone-line blowing up into the transmissionline. Twelve outages, totalling 22 hours 46f minutes, being attributable to these troubles. Further telephone-poles have been put in to reduce the spans, and more work will be done in this connection during the coming year. This line was not put out of action during the earthquake, but on the telephone-line the wires were twisted. Tuai-Wairoa Line. —Some trouble has been experienced on this line during the year with broken binders, insulators, and pins. Four outages, lasting 3 hours 30J minutes, were attributable to this cause. The earthquake on the 3rd February did some minor damage to the line, which, however, was quickly remedied. Stratford - New Plymouth Line.—This line has been maintained and operated at 33 kv. during the year by the New Plymouth Borough Council. Transmission-lines (11,000 Volt). Tuai - Lake House and Thomas's Mill—The line to Thomas Bros.' Mill has been connected in to the Lake House line during the year, and has operated well. Mangaore-Shannon.— -This line has been operated and maintained by the Horowhenua Power Board throughout the year. Khandallah - Hult Valley Power Board : Duplicate Circuit.-- -This line delivers power to the Hutt Valley Power Board, and suffered forty-three outages, totalling 2 hours 31J minutes. Khandallah - New Zealand Railways : Duplicate Circuit. —This line, delivering power to the railway workshops, had thirty-two outages during the year, totalling 2 hours 59f minutes. These lines were operated for some part of the year in parallel with the Hutt Valley lines. Khandallah - Wellington Meat-export Co.—This line has suffered eight outages during the year totalling 13J minutes. Transmission-lines. — General. During the year all the insulators have been cleaned, with the- result that no interruptions have occurred due to salt-deposit on insulators. The fifth year's series of tests on insulators has practically been completed, these generally bearing out the results of previous years' tests. A live-line-testisg class was again held at Tuai. Pole-testing for depth of sap has been continued, and a fair amount of work done in strengthening and replacing weak poles where necessary. Further earthwire has been removed from lines during the year, to enable use to be made of the insulation resistance of poles in preventing flash-overs. Further vibration troubles have been experienced on A.C.S.R. lines, and vibration-dampers and special clamps have been installed to prevent failures from this cause. Lightning storms recorded during the year numbered four. One of these was responsible for an outage on the Tuai-Napier line, and one was responsible for the failure of a trifurcatins-box on No. 1 Hutt feeder at Khandallah. 8 Earth-resistance tests were taken over the whole transmission system and, where necessary, extra precautions taken to bring the resistance values down to standard. 111. Earthquake on the 3rd February, 1931. The first sign of this earthquake was at 10.48 a.m., when the Bunnythorpe East line opened at Mangahao and both Tuai-Napier lines opened at Tuai. Telephonic communication was cut off from Mangahao north of Waipukurau, and Tuai was entirely isolated. Supply was restored within half an hour to all stations south of Waipukurau, to which station power was resumed at 12.27 p.m. from Mangahao after minor repairs were effected. To carry all load Wellington City steam plant was called on to render assistance. Tuai resumed power to Gisborne at 8.30 p.m. on the 3rd February, and to Wairoa about noon on the 4th February. Telephone communication from Mangahao to Napier was established on the night of the 3rd, and to Tuai on Thursday, the sth. This, however, was intermittent owing to the frequent aftershakes tangling the wires together, but on the 6th good service was obtained. On the 4th February power at 11 kv. was delivered to Napier from Waipukurau Substation After temporary repairs had been effected to the Tuai-Napier lines, supply from Tuai was given to Napier at 11 kv. on the east line, and to the general system at 110 kv. via the west line on the 12th February, Tuai paralleling with Mangahao at 4.10 p.m. On the 13th February, about 1.40 p.m., a heavy earthquake put the Tuai-Napier line out again owing to the isolating-switches at Waikoau shaking open. The shake also interrupted telephone communication between Napier and Tuai. Communication between Mangahao and Tuai was eventually established by means of the Palmerston North and Gisborne Radio stations and Tuai paralleled once more with Mangahao at 9.10 p.m.

D.—l.

Owing to the Napier transformers and 110 kv. switch-gear being in a very chaotic state, the spare 1,500 kv.a. transformer from Mangamaire was transported to Clive Eailway-station. The roads to Napier Substation were so damaged that it was impossible to bring this transformer to the substation site, so it was decided to erect a temporary substation at Waiohiki, across the Tutaekuri River from Taradale. This station was put into commission with 1,500 kv.a. transformer solidly connected to the line and an outdoor type 11 kv. switch cubicle on the L.T. side controlling a three-quarter_ mile temporary line to the 11 kv. switch-gear at the substation. Supply at 11 kv. was then discontinued from Tuai, and both Napier-Tuai lines used to supply power at 110 kv. to the general system. This substation was in operation until 29th March, 1931, when the main transformers were put back into service at Napier after repairs had been carried out to switch-gear, and the transformers had been reconditioned and dried out. The damage done to the system was as follows : — Substations. Waipukurau. —Two post-insulators supporting the 110 kv. leads to the transformers were broken and the battery was badly damaged. Napier.—The low-tension switch-gear and cables, except for a single-core pothead which had punctured, were undamaged. Three transformers were shaken off; their pads and crashed on their sides. The fourth was lifted out of the runway, but remained on the pedestal. Seven out of the eight high-tension bushings and all eight low-tension bushings were broken. Conservator-tanks were buckled, slight damage was done to tins, and all oil-piping extensively damaged. All oil was lost. These transformers have since been reconditioned and are now back in service, no apparent damage having been sustained by the windings. Practically the whole of the isolating-switches and air-break switches were badly damaged, some being ruined. These have since been repaired or replaced by spares. The oil circuit-breakers sustained no damage, except for three broken bushing-caps. The battery inside the building was totally wrecked. The lightning-arresters were badly shaken, but were easily repaired. Most of the bushings on the synchronous condenser switch-gear and auto transformer were broken. These are awaiting new bushings now on order, bat owing to the state of the building the condenser cannot yet be run. The capacitor had two of its supporting insulators and one bushing broken. The building suffered very severely, particularly the workshop section. Several columns and beams were cracked. The temporary end-wall collapsed, and a good portion of the windows were cracked. Of the outbuildings, only the operator's cottage was damaged, the building being badly wrenched, and the chimneys collapsed. Arrangements are being made to repair the building-damage. Gisborne. —At this substation the transformers moved and dragged three insulators off the airbreak switch above, breaking three bushings on the 50 kv. 0.C.8. These have been replaced. The only other trouble experienced was the breaking of the earthenware pipes for returning transformer cooling-water to the well, necessitating water being carted from Gisborne till repairs were effected. Wairoa. The earthquake caused the transformers to* run of! their pads, with consequent damage to three 50 kv. bushings, which have been replaced. An 11 kv. cable was also broken, but no other damage was done. Transmission lines. Waipwkurau-Napier. —No major damage was sustained by the transmission or telephone lines, but cross-a.rms were thrown out of alignment and weights thrown off the insulator-clamps. The telephone-lines were also twisted together in two places. These faults were very quickly remedied, the telephone-line being in service again on the night of the earthquake, and the transmission-line was never rendered unfit for service. Napier-Tuai limes.—Tower 220 on this line collapsed owing to the foundations slipping away, putting this duplicate line completely out of action. A temporary H structure was erected on a piece of fairly solid country, and the line restored on 12th February. Several towers had their foundations badly shaken, cracks having opened up round the footings. These were filled and rammed as soon as possible. A deviation to cut out the broken country round Tower 220 was surveyed, eight spare towers and cable were shipped to site and erected, and the new piece of line connected in for service on 31st May. The telephone-line was also badly shaken, but the damage was principally confined to twisted wires. Reconstruction work was difficult owing to all roads being closed by landslides and slips. On 13th February a severe earthquake shook open the isolating-switches at Waikoau and Kotemaori, cutting off power from Napier. This also dislocated the telephone service again. The isolating-switches at Kotemaori and Waikoau have had jumpers placed across them. Tuai-Gisborne.— No great trouble was experienced on this line, which remained in service until cut out for repairs at Gisborne Substation. Cracks opened up round several poles. These cracks have been filled and rammed. Tuai-Wairoa. —Damage to this line was confined to a few broken binders and insulator-pins, which were very quickly replaced.

D.—l.

Waikaremoana Power-station, Headwords, and Village. Access Roads. —All roads were blocked by landslides and slips, Tuai being completely isolated, the worst being a huge landslide at the 20 m. peg from Wairoa. Fife-line. —No damage was done except for the tilting-back of a few cradles. Earth Dam.— Small cracks up to 2 in. wide and 4 ft. deep have been filled and rammed. Power-station. —Various small cracks appeared in the building, but no appreciable damage was done either to the building or the apparatus. Staff Village. —Practically every chimney was demolished. The main water-supply pipe burst at the entrance to the village. Repairs have been effected and conditions are now normal. Power Boards' Damage. Hawke's Bay Power Board. —This Board suffered severely not only on account of the earthquake, but also the fire which afterwards swept through Napier, destroying their store. A large number of transformers were shaken down ofi their platforms, and the distribution-lines were reduced to a mass of wreckage. Great strides have been made with the rehabilitation of services, as evidenced by the fact that the load immediately after the shake was reduced to about 400 kw., principally the Napier Borough pumping-plant, while early in June the load has reached almost 4,000 kv.a., which is greater than the peak load for 1930-31. Wairoa Power Board. —While not a great deal of damage was done during the earthquake, this Board suffered from the loss of their principal consumer, the freezing-works, whose buildings were destroyed by fire just subsequent to the shake. The load taken by the Board has therefore fallen considerably. General,. —Considering the severity of the earthquake, suprisingly little damage was done. The transmission-lines stood up in every case except Tower 220 on the Napier-Tuai line, where a huge landslide took place. One lesson learned is the necessity of fixing transformers and other apparatus securely to their foundations. This is being done all over the system. Oil switches which were bolted down suffered no great damage. The system was back to normal operation on 29th March, when the reconditioned bank of 110 kv. transformers was put back into service at Napier. IV. Construction. Mangahao Power-station. —The delivery of the relay-protection equipment was completed during the year, and the erection of same is in an advanced state. An acoustic shock-absorber was fitted to the main telephone system to guard operators from excessive shock to the eardrums during switching operations, lightning-storms, &c. A new transformer, protection system, and metering equipment were installed on the headworks line. Waikaremoana Power-station. —Relay equipment was received and installed during the year, and is practically ready for operation, only the final testing being required. An acoustic shock-absorber was fitted to the telephone, following satisfactory results from that installed at Mangahao. Adjustments were made to the turbine relief-valves, and these are now operating satisfactorily. Duplicate power-supply has been run to the governor-motors. The earth-filling at Lake Kaitawa at the position of the old spillway weir was completed and the water-level indicators at Kaitawa weir installed. Khandallah Substation. —The installation of the relay equipment is practically complete. A temporary wood-pile structure was erected as a terminus for the Khandallah-Melling transmissionline. A 110 kv. 0.C.8. has also been installed to control this line. Bunnythorpe Substation. —The renovation of the old building damaged by fire last year, and extensions to same to house new apparatus, made necessary by growth of load and the extension of the system, was completed during the year, and a good start has been made with the installation of apparatus therein. New 11 kv. switch-gear is being installed. The new storage-battery and charging-set has been installed. A telephone switch-board has also been installed. The two 0.C.8.s (for the control of the two Mangahao lines) which were damaged by fire in the substation building while awaiting installation are being reassembled, one being completed. A new bank of transformers has arrived at site and will be dried out shortly. To control the 110 kv. side of the two transformer-banks, have been delivered to site and will be installed shortly. A new lightning-arrester has been installed. Wanganui Substation. —The permanent water-supply system has now been completed. The stable has been converted into single men's quarters. A new lightning-arrester has been installed. Steelwork and switchgear have been delivered for the proposed extensions. The 0.C.8. to control the Stratford lines has been received, and erection will proceed shortly. A new storage-battery and charging-set has arrived. Woodville Switching-station. —The relay system has been completely installed, and was finally tested and put into service in early June. The 0.C.8. controlling the Bunnythorpe line was installed, and is now in service. A new workshop and battery-house were built, and the battery installed. This station is now complete until it is necessary to duplicate the lines from Napier. Dannevirke Substation. —The new relay equipment has been received on site and a start has been made to install same. A new 0.C.8. for controlling the Woodville line has been erected and put into service.

72

D.—l.

Waipukurau Substation. —The relay equipment has been received, and the erection is practically complete. The 0.C.8. for the Dannevirke line has been received and put into service. Napier Substation. —The relay system has been installed and was ready for final testing before being put into service when the destruction of the battery by the earthquake prevented the system being put into operation. Further work at the station is referred to in the report on the earthquake experienced on 3rd February, 1931. Gisborne Substation. —An additional pumping-set was installed for the cooling-water supply for the transformers. Hawera Substation. —-Preliminary design work and arrangements have been finalized. Stratford Substation. —Preliminary design work and arrangements have been finalized. New Plymouth Substation. —Preliminary design work and arrangements have been finalized. Melling Substation. —The name of this substation was changed from " Belmont " to " Melling." The Hutt Valley Power Board will receive supply from this substation. Contract for erection of buildings has been completed. Contracts for permanent equipment have been let. A temporary substation, comprising a wood-pole structure carrying an air-break switch, transformer-bank on cribwork pedestal, and 11 kv. metering-cubicle, have been completed. Transformers have been driedout and are ready for service. Khandallah - Melling 110 kv. Transmission - line. — Survey has been finalized, and construction will be completed early in July. Wanganui-Stratford 110 kv. Transmission-line. — (a) Wanganui-Hawera Section : A contract for the cartage, delivery, and erection of main-line structures and telephone-poles was let in November. Two steel towers have been erected for the Wanganui River crossing. Wiring of this section commenced in May, and to date thirteen miles of transmission-line and fifteen miles of telephone-line have been completed. (b) Hawera-Stratford Section : A contract has been let for the pole-erection, and a start made. Stratford - New Plymouth 50 kv. Line. —Two extensions of this line have been surveyed, and an early start will be made with erection. Upper Development, Waikaremoana. —Work of considerable interest is at present being carried out around the outlet as a preliminary step to the second scheme. A comprehensive study of the country around the outlet of the lake has been in progress during the year. This includes surface-surveys, surveys of underground chambers, a more intensive geological study, and investigations to determine the location and character of the rocks and underground passages through which the water escapes from the lake. V. Load. During the year Mangahao and Waikaremoana generating-stations have run very well in parallel, W T aikaremoana taking the base load and Mangahao supplying power during peaks. The only occasions when standby stations came into operation were — (1) On peaks when Mangahao was out of commission during the Christmas - New Year holidays for overhaul of valves : (2) During an arranged shutdown on the Mangaore-Wellington iines for repairs to the lines : (3) During the period subsequent to the earthquake on the 3rd February while the TuaiNapier line was out of commission, and while the load was greater than the capacity of Mangahao Power-station. (4) While a machine at Waikaremoana was under repair and test, Wellington City steam plant was brought in for a total running-time of approximately 307 hours. Wanganui-Rangitikei Power Board steam plant was called on for 64J hours' running. Hastings Borough, whose plant was undamaged during the earthquake, carried their own load thereafter until the Hawke's Bay Power Board's system was sufficiently repaired to enable them to supply power to the borough. Through having Wellington City and other plants available, it was possible to avoid restrictions on the use of power whilst the Napier-Tuai line was being repaired after the earthquake. The maximum load on the system was 44,660 kw., and the total number of units generated during the year was 210,373,650. The total connected load was 279,053 kw. WAITAKI ELECTRIC - POWER SYSTEM. 1. PoWEB-HOUSE - GrLENAVY TkANSMISSION-LINE. A start was made on tower erection in May, 1930, and good initial progress was made, but running shingle and water met with on river-terrace demonstrated the necessity for extra pumping equipment. Towards the end of March, 1931, a start was made on transporting insulators and cable to towersites in readiness for stringing of conductor, which began about the middle of April. At the end of March, 1931, nineteen towers remained to complete this section of the work, and in April a start was made on stringing conductor. At the end of June one circuit was completed and livened up for power-supply from the Lake Coleridge system.

2. Power-house - G-lenavy Telephone-line. In conjunction with power-house - Glenavy transmission-line construction, forty miles of cadmium copper telephone-line and six sectionalizing huts have been completed during the current financial year. Special pole structures and 7/16 copper conductor were used at Hakataramea Stream and Waitaki River crossings, the spans being approximately 9 and 8 chains respectively. 3. Waitaki River Crossing. During the year a careful watch was kept of the H pole in the centre of the river, and bouldernet protection round this structure was built to take care of any conditions that would arise due to abnormal floods in the river. The general branch put in hand the work of building the concrete-cylinder foundations on the island to support the central tower for the new crossing. Two 88 ft. towers, together with the special strain structures and concrete anchors for the same, were erected on the north and south banks respectively. Early in February, 1931, exceptionally heavy floods hindered progress on this work considerably. Immediately on completion of the central tower, wiring operations were resumed, and on the 11th March, 1931, all six-phase wires erected, thus providing two circuits across the river. A deviation of the existing 66 kv. line on the Canterbury and Otago sides of the river was pegged out to line in with the new crossing, and erected. 4. Timaru-Oamaru Transmission-line. The work of duplicating this line has been held over till next financial year. 5. TIMARTJ-O AMARU TELEPHONE-LINE. The necessary material for this work is available, but erection of same is postponed for the present. In January, 1931, three additional transformer-pads were cast to suit the revised substation layout and four 1,767 kv.a. transformers were shifted from Addington. 7. Glenavy Substation. The erection of two cottages, pump-house, and tank-stand has now been completed. Roof-trusses for substation-building have been unloaded and stored at Glenavy. Two turntables for outdoor-station traverser track are also to hand. Switch-gear and steelwork commenced to arrive in January last, and are now practically complete. Everything is in readiness for construction work to commence immediately the tower-foundations have been pegged out. Six huts ex Waitaki River crossing were transferred to the substation-site, and are being used for storing electrical equipment and also for a temporary workshop. 8. Power-house Plant and Equipment. Auxiliary generators and turbine units complete with pipe-line and switch-gear were received. Girders and towers for " B structure " were assembled on ground and checked for drilling, &c. Galvanized steel for the headgate-screens has been received. Main headgate-winches have arrived. Seven 5,500 kv.a. single-phase transformers were received. Electrical equipment, girders, &c, for 120-ton crane arrived, and have been stored on the site. One 46 ft. cross-girder was received in a badly buckled condition. A new girder was ordered to replace the damaged member and this arrived in September last. 9. Turbines. The component parts of the two 23,000 b.h.p. Francis turbines have been received on the siteA start was made on turbine-erection towards the end of February, 1931, when sections of the suction-tube angle-irons were assembled and checked for pitch circle diameter, and pipe manifolds for water-supply to filter were made up for scroll cases Nos. 1, 2, and 3. No. 1 turbine-foundation angle was assembled round the top of the draught-tube and plate marked off for cutting out R.L. 688 ft. 7| in. The same procedure was carried out on No. 2 unit. This constituted the work on turbine-erection up till the 31st March, 1931, but it is anticipated that the installation of both machines will be well in hand by September, 1931, after which a start will be made on generator-erection. 10. Generators. Component parts for No. 1 and No. 2 generators have arrived on site. ' ' All parts for turbines and generators have been carefully inspected at regular periods, and necessary action taken to keep all machinery in good order and in readiness for erection.

11. Outdoor Station. The construction of steel structure was commenced in July, 1930. A certain amount of difficulty was experienced on the construction of the steelwork due to naccurate drilling of footings and bad fitting of girder and tower members. The steel structure has now been completed, including lightning-arrester and isolatmg-switches. To date all necessary work has been completed on the north line from Lake Coleridge, and on 28th June, 1931, power was passed over the power-house - Glenavy transmission-line at 66 kv., giving supply to the works at Waitaki Hydro. 12. Motor Transport and General. ■A four-stalled motor-garage for departmental vehicles was erected and a 40 ft. extension made Six hundred and eighty-two drums of transformer-oil were unloaded and leaking drums attended to. Five oil-storage tanks were received on site and inspected. Earth tests have been carried out in likely localities for power-house and lightning-arresters and steel structure, but to date satisfactory results have been difficult to obtain on account of the nature of the country. HYDRAULIC DESIGN. Arapuni. Plans have been prepared for the remedial measures as outlined in Professor Hornell's report. Extensive model tests were made to determine the best means of preventing further erosion in the overflow-channel, and plans have been prepared for lowering the water to the Waiteti Flat in two stages so that the energy of the falling water should be absorbed gradually. Waitaki. Further work has been done on the dam, including a deep cut-off wall, separate from the dam, to prevent the development of under-pressure ; the installation of permanent sluices to by-pass the water through the dam ; the protection of the rock downstream of the dam and the disposal of the energy of flood-water falling over it. In connection with these latter a number of model experiments have been carried out. DESIGN OFFICE WORK. During the year under review the following design-work was carried out in connection with new developments and extensions to existing developments : — Lake Coleridge System. The advent of an abnormally dry season necessitated a curtailment of the output of Lake Coleridge, resulting in the decision to install a standby Diesel generating-station of four units at Lyttelton, with provision for extension to seven units at a later date, by transfer of the Diesel sets from Penrose station. The site chosen has the advantages of direct access by railway siding from railway or wharf, and an unlimited supply of cooling-water from the harbour, whilst the fuel-oil supply can be pumped direct from the Oil Co.'s storage-tank. To provide for the interconnection of the Diesel station with the "Lake Coleridge system the line-conductors, switching-arrangements, and protective relay equipment required on the AddingtonLyttelton lines were investigated. Lyttelton Diesel Station.— With the exception of a few minor details the design and layout of the Diesel station building and equipment was carried out during the year. The following are some of the subjects dealt with : — (a) Design of Diesel station building. (b) General layout of site. (c) Design and specification for 200-ton fuel-oil storage-tank. (d) Design of compound wall and railway siding. (e) Layout of equipment in power-station. (/) Design of cooling-water and fuel-oil piping systems. (g) Design of machine-foundations. (h) Design of silencer-pits for engines. (i) Design of oil-sump tanks. (j) Design of transporter for crane. (k) Layout of cables and cable pits and ducts. In preparation for the interconnection of the system with the Waitaki Power-station, and at a later date with the Waipori Power-station, the design work in connection with the additional switch-gear and protective equipment for the system was carried out as the details of the equipment ordered came to hand. The provision of increased transformer-capacity at some of the substations to take care of a reasonable growth of load, and inter-connecting auto-transformers at Timaru to tie in the 66 kv. with the 110 kv. lines also occasioned a certain amount of design work. The following design work was also carried out for this system: — Addington.— Preliminary drawings were prepared for the proposed new workshop, test-room, and office building, and for the extensions to the substation building to house the new 10,000 kv.a. synchronous condenser. Km»™,—Design and specifications for traverser-truck and turntables. Oamaru. Eevised layout of site ; foundations and traverser-truck for 5,300 kv.a. transformerbank ; design and specification for traverser-truck.

D.—l.

Mangahao-Waikaremoana System. With the growth of load in the Hutt Valley area the 11,000-volt supply-lines from Khandallah were becoming inadequate for the supply to the district, so it was decided to put in a new 110 kv. substation at Melling with a 110 kv. supply-line from Khandallah, which will ultimately be extended to Masterton Substation to give an alternative 110 kv. supply-line to Khandallah. During the year additional transformer-capacity was ordered for some of the larger substations to provide for the estimated growth of load. In connection wth the extension of the system from Wanganui to New Plymouth with substations at Hawera, Stratford, and New Plymouth, further design work was carried -out. Wiring and phasing diagrams for the main line protective relay equipment were prepared and transmission calculations for the system were carried out. Bunnythorpe. —Drawings and specifications were prepared for the reconstruction and extension of the substation building. A foundation drawing was prepared for the capacitor. Melling. —The layout drawing of the site and drawings of the 11 kv. and 110 kv. switch-gear for tendering purposes were prepared. The drawings and specifications for the substation-building contract were prepared. A traverser-truck for handling the transformers and a turntable were designed, and a foundation drawing was prepared for the turntable and transformer-banks. The following design work was also carried out for this system :— Khandallah. —Preliminary layout 110 kv. switch-gear extensions ; layout of temporary switch - gear for 110 kv. line to Melling ; layout of proposed 110 kv. city substation ; foundations for capacitors. Napier. —Foundations for capacitor. Hawera. —Drawings for substation-building contract; preliminary layout of switch-room. Hawera, Stratford, and New Plymouth. —Layout of sites for construction purposes. Hawera and Stratford. —Design of traverser-trucks and turntables. Arapuni-Hobahoka System. The Grand Junction steam plant was re-erected at Huntly, and in this connection designs and specifications were prepared for a 50 ft. steel chimney and foundations for same. Hamilton and Bombay. —Preliminary layout drawings were prepared for the extensions to the steelwork and switch-gear to provide for additional lines, transformer-capacity, and switching and relay equipment. Arapuni.—k drawing was prepared for the temporary end-wall supports. Waitaki Power Development. The design of the power-house and main units was outlined a year ago, but much detail work remained to be dealt with during this year. The Napier earthquake led to investigation of resistance to earthquake stresses. The dimensions of the power-house are so great that conditions might be more severe than for a smaller building. Consequently, it was decided to provide against a horizontal acceleration of g, corresponding to an earthquake of intensity about 8| on the Rossi-Forel scale. These considerations have amounted almost to redesigning the power-house, retaining the general arrangement, but increasing the strength and stability to an extent that might not have appeared to be justified before the Napier earthquake. Architectural features have been reduced to a minimum overhang, diagonal bracing has been introduced in walls and some openings have been closed with reinforced concrete panels. The penstock and scroll cases of the turbines had already been rechecked on a conservative basis, and any possible sources of weakness dealt with. The stability of the building has been increased by eliminating stair-wells from the lower part of the annexe, and by constructing part of the scroll cases of the three future units, as well as by a wall on the intake side of the structure and buttress piers between the draught-tube outlets. In addition to the design being checked over and revised as described above, much detail work has been shown on drawings, notably for turbine- and generator-floor foundations, cable-shelves, piping systems, and auxiliary units, and for testing-apparatus, the latter being of a recent design, which gives remarkably accurate results. Foundation drawings were prepared for the outdoor switch-gear and steelwork for the powerstation, which also showed the layout of traverser-trucks and turntables. Transmission-lines. Waitaki-Glenavy 110 kv. Steel-tower Line. —Drawings have been prepared showing location of towers on route also assembly drawings of insulators. Timaru-Oamaru Line Duplication. —For a distance of two miles south of Timaru Substation it was decided to install double-circuit steel towers to carry both the existing and the new circuits, thereby causing less obstruction to the property on route than two separate wood-pole lines. Wanganui-Stratford 110 kv. Line. —Route plans have been prepared showing location of woodpole supports, also detail drawings of structures. A.rapuni-Edgecumbe 110 kv. Line. —Only part of this line was dealt with, supports being located on route-plans, also consideration was given to a special crossing over Lake Roto-iti which was deemed advisable in order to avoid sulphur springs in the Tikitere district. It has been found that copper conductors are badly affected by sulphur fumes. Arapuni-Stratford 110 kv. Line. —Between Taumarunui and Stratford the projected line passes over difficult country with steep papa ridges, and preliminary tests of the holding-power of anchorage in papa have been made. A light type of steel tower has been decided upon for this part of the line. Khandallah-Melling Line. —Various drawings and conductor sag and tension tables have been supplied for use on the erection of tnis line. Waikaremoana-Naqrier Line. —At one point on this line damage was caused by the earthquake in February and occasioned a certain amount of work in connection with the temporary measures for repairing the line also for the deviation finally decided upon for the permanent repair.

D.—l

Waitaki River Crossing. —This is part of the Timaru-Oamaru line, and reconstruction of the line across the river became necessary owing to one of the original towers being washed out in a flood. A new layout was prepared with only one tower in the river-bed instead of three on the old line. WaimaJcariri River Crossing. —This is on the route of the Addington-Southbrook line and some reconstruction became necessary owing to the wide diversion cut being made there. A single-span crossing on steel towers has been adopted. Lyttelton-Woolston Line. —A new line with heavier conductors was required to cope with the supply of power from the Lyttelton Diesel station. Quantities and a new design for the hill section of the line were made up and stringing data supplied for the conductors. General. —A specification was drawn up for concrete telephone-poles, and tests on same were supervised. Drawing and chart also prepared in connection with this pole. Investigation is being made into most suitable form of guy-insulators for wood-pole structures. In connection with line-insulators, data was prepared giving method of calculating surface-leakage form-factor for use with insulator specifications. ELECTRIC - POWER BOARDS. The development of the reticulated area of Electric-power Boards has continued to make progess during the year. There are now forty-five districts constituted, and forty actually carrying out the distribution and sale of electrical energy (August, 1931). The total area covered is 69,294 square miles, or 64 per cent, of the total area of the Dominion ; the total population concerned is 1,004,081, or 68 per cent, of the total population of the Dominion ; and the unimproved value of the land included in the electric-power districts and outer area is £257,184,874, or 73-5 per cent, of the total unimproved value of the Dominion. 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 cities of Wanganui, Palmerston North, and Invercargill, and the boroughs of Timaru, Napier, Hastings, Blenheim, Greymouth, Gisborne, and Oamaru are included. The advantage of Power Board organization is more obvious to rural than to urban ratepayers, and yet the above position indicates that some of the more important centres have realized 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 question of administration and operating costs in Power Board areas where more than one organization is engaged on the business of electric supply is being investigated with a view to arriving at an approximation of the resultant savings to be obtained if amalgamations or absorptions are effected. If such investigations show the expected savings, then it is in the interests of national economy generally and of the consumers in particular that effect be'given to the above objective. The following tabulation has been prepared to show the present position of each city, borough, and town district in relation to Power Boards actually in operation, and it reveals the fact that the benefits of electric supply have reached many places which might otherwise not yet be enjoying these benefits. Included counties have not been scheduled.

Power Boards not yet Functioning.

Table XIII gives details of the date of constitution, the area, population, and rateable value of each of forty-five power districts already formed, also the amounts of the loans already authorized, and the voting on each poll taken. The total amount of the loans authorized by the thirty-nine districts which have taken their polls is £13,047,156. The population of the districts concerned is 949,094, so that the loans authorized amount to £13-75 per head of population, as compared with £13-8 last year. The unimproved valuation of the districts is £227,177,927, the loans authorized amounting to 5-75 per cent, of the unimproved rateable value of the lands pledged as security for the loans. The voting at the polls totalled 65,160 to 12,155 — i.e., a majority of 69-0 per cent. Table XIV shows the capital outlay incurred by each Board up to the end of the financial year 1930-31, the revenue and annual expenditure, and the amount of rates struck and collected. The total capital outlay by the thirty-nine Boards which have started construction is £13,637,177, a small proportion of which is on works not yet in service. The gross revenue from the sale of electricity by the thirty-nine Boards which have commenced supply was £2,223,879, of which 29-5 per cent, was received by the Auckland Power Board. The general result is a profit over the whole business of the Power Boards of £179,422 for appropriation to depreciation and reserve funds, &c. During last year four of the Boards struck a general rate, which was collected in all cases, and five of the Boards struck special rates for the security for loans, which were collected in two cases. LOCAL ELECTRIC-SUPPLY SYSTEMS. Including the Government plants, there are now (31st March, 1931) forty-one public electric-power stations in the Dominion, as compared with thirty-nine last year. One new hydro station (Alderton Co., Kerikeri), and one new oil station (Rawene) came into operation during the year. The total installed capacity (excluding standby plant) has decreased during the year by 30,075 kw., or 11-8 per cent, (from 254,038 kw. to 223,963 kw.), while the sum of the maximum loads has increased by 6,017 kw., or 3-45 per cent, (from 175,211 kw. to 181,228 kw.). The decrease in installed capacity is due to Arapuni Station being temporarily closed down. The proportion of installed plant is now as follows : — Stations. Kilowatts. Proportion per Cent.

The total population included in the various areas of electric-power supply is 1,400,214, or 94 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. The maximum demand per head of population in the areas supplied is 0-129 kw., which is nearing the allocation of 0-15 kw., or 0-2 h.p. per head of population, the basis of the design of the Government schemes. The units sold per head of population supplied were 489, as compared with 490 last year. The total length of distribution-line is 20,658 route-miles, as compared with 19,128 last year, an increase of 1,530 miles, or 8 per cent. The number of consumers per route-mile is 14-5, as compared with 14-9 last year, the decrease being due to the extra mileage of new lines erected during the year to which the full number of services are not yet connected, and to the increased proportion of country lines.

The maximum power-demand per route-mile is now 8-76 kw. ; the sales 33,000 units, and the revenue £210. The units are less than last year (35,000), and there is a slight decrease in revenue, as against £220 last year, and there is a decrease over the corresponding maximum demand of 10-9 kw. last year. These decreases can be directly attributed to the general economic conditions which have been a feature of the past year, and in a smaller degree to restricted outputs from Lake Coleridge and Waikato systems. The revenue per kilowatt of maximum load of all stations was £24, as compared with £24 last year. The water-power stations show a revenue of £24-1 per kilowatt, steam stations of £23-3 per kilowatt, oil stations of £51-2 per kilowatt, and gas stations of £44-9 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-nine distributing authorities, eighty-three showed a profit for the year amounting to £755,415, and sixteen showed a loss amounting to £65,539. The general result is a net profit for the whole Dominion of £689,876, after paying working-costs (£2,094,736) and capital (interest and sinking fund) charges (£1,582,497) at the rate of 5-45 per cent, on the total capital outlay of £29,185,268. This shows a net profit of 2-38 per cent., as compared with 2-76 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 94 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, and Table XX shows in condensed form the financial statistics for each supply authority.

BROKEN WIRES AND POLES. During the year ending 31st March, 1931, there were 760 instances (1,019 broken wires) reported by electric-supply authorities, with 93,121 miles of conductor erected. The corresponding figures for the previous year were 1,811 broken wires, and 90,710 miles of conductor in use. Falling trees were the principal cause of the breaks, and accounted for 254 per cent, of the total, as against 40-6 per cent, for 1930. As regards broken poles, 450 instances were reported for the year, of which 352 were New Zealand blue-gum. For 1930 the total number of broken poles reported was 561, and it is still evident that electric-supply authorities who experimented with New Zealand blue-gum and nondescript Australian " hardwoods " are now being called upon to make early replacements after approximately five to seven years of pole-life. GROWTH OP LOAD. The total connected load at end of the year under review was 1,155,111 kw., as against a total of 886,905 kw. for 1930, an increase of 268,206 kw., or 30-3 per cent. Statistics pertaining to the increasing use of electric ranges, electric water-heaters, and milkingmachines, have been collected and scheduled for some years past, and from the following table it will be seen that during the period 1925 to 1931 the growth has been phenomenal.

The Electrical Supply and Wiring Regulations, which were gazetted in 1927, with the intention of revising same after two years' trial, are now being revised. It is expected that the work of revision will be completed towards the end of 1931. INSPECTION Or 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. It is satisfactory to be able to say that the electric-supply authorities facilitate these inspections, and, almost without exception, give prompt attention to the rectifying of any defects discovered. In 1929 it was intimated that more attention would be paid to the inspecting of consumers' installations, and periodical inspections of this nature will be continued in co-operation with the activities of the Electrical Wiremen's Registration Board. LICENSES ISSUED. The following water-power and electric-line licenses and permits have been issued during the period from July, 1930, to July, 1931 : Licenses—Wilson's (N.Z.) Cement Co. (amendment) ; Wilson's (N.Z.) Cement Co. (Hikurangi) ; North Auckland Power Board; Heathcote County Council (consolidating) ; Raetihi Borough Council (amendment) ; New Zealand Sounds Hydro-electric Concessions (variation) ; D. J. Barry, Ruatoria; Christchurch Tramway Board (trackless trolly) ; M. N. Wallis, Okete ; Maniototo Hospital Board (amendment) ; W. Morris, Tirau ; Malvern Power Board (amendment). Permits — J. W. Fraser, Hawarden ; E. D. Hodges, Waitekauri; A. Schreiber, Oparau ; A. Doig, Mawheraiti; R. Bruce, Pukerua ; E. Rogers, Riverside. The license held by J. Barnett, Leeston, was revoked. ELECTRIC APPLIANCES BOARD. Pressure from the electric-supply authorities and supported by the Electrical Traders' Federation has again been 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, and in response thereto a draft Bill has been prepared. ELECTRICAL FIRES. During the year there were thirty-three fires reported to the Department by the electric-supply authorities and attributed to electrical causes. The corresponding figure reported for 1930 was twenty-four fires. ELECTRICAL ACCIDENTS. During the year ending 31st March, 1931, there were reported to the Department thirty-one electrical accidents, of which eight were fatal. The corresponding figures for 1930 were twenty-four and eight respectively. REGISTRATION OE ELECTRICAL WIREMEN. The year has been a busy one for the Registration Board, and a total of fifteen meetings have been held during the year ended the 30th June, 1931. There has been a slight increase in the total registrations during the above period, a large increase in the number of reports of defective work, and an increase in the number of reports of breaches of the Act. The number of candidates for examination has shown a marked decline over the previous year. A certain amount of delay and additional work is occasioned by the lack, in some cases, of the details which should accompany reports of defective work and breaches of the Act, and a further endeavour was made during the year to bring under the notice of the local authorities the necessity for supplying full reports. The reinspections of consumers' installations has shown that a large number of extensions have been made to existing installations without notice to the electrical-supply authority, and that they have been connected up without inspection or test. In some cases dangerous conditions have been found to exist through this practice, and drastic action is required to put a stop to it. Forty-three prosecutions for breaches of the Act were taken by the Registration Board, and several prosecutions were taken by the local authorities. Sixteen Inspectors of electrical wiring, 149 electrical wiremen with full registration, and eleven electrical wiremen with limited registration have been registered during the year ended the 30th

June, 1931, and twenty-one provisional licenses have been issued during the same period. Of the 149 electrical wiremen granted full registration 138 qualified by examination. The number 6f candidates for the examinations held during the year has shown a decline from the previous year, being 543 for the written part and 447 for the practical part, compared with 597 and 542 respectively for the previous year. The results'of the examinations are still very disappointing, only 21 per cent, passing in the written part and 25 per cent, in the practical part. The highest marks gained by any candidate also show a falling-ofl, being seventy-eight in the written part and eighty-two in the practical part, compared with eighty-nine and ninety-six respectively for all examinations. For the year ended the 30th June, 1931, there have been eighty-eight reports of defective work, and these have been dealt with as follow : The certificates of sixteen wiremen were endorsed for defective work, seventeen wiremen were censured, and fifteen wiremen were cautioned. Thirteen reports are still under consideration. One Inspector was reported for unsatisfactory inspections, and was cautioned. The very large increase in reports during the year ended the 31st March, 1931 —namely, from forty to ninety-nine —indicates that the electrical-supply authorities are taking more advantage of the facilities for disciplinary action provided by the Act. For the year ended the 30th June, 1931, there have been eighty-two reports of breaches of the Act. Forty-three prosecutions were taken by the Registration Board during the above period, and others are pending. Fines and costs amounting to £220 were imposed during the year ended the 31st March, 1931.

APPENDIX E.

SEVENTH 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 seventh annual report for presentation to Parliament through the Hon. the Minister. The report covers the period from the Ist April, 1930, to the 31st March, 1931, though a number of matters referred to are carried beyond the latter date for convenience and completeness of record. General. The total expenditure from both funds for the year amounted to £2,097,390, compared with £2,317,444 for the previous year. The expenditure from the Revenue Fund was £1,386,140. This amount is an appreciable increase on the figure for the previous year, which was £1,246,027. The increase, however, was not due to any expansion of the Board's normal activities, but was brought about by the operation of the Finance Act, 1930, which transferred certain charges from the Consolidated Fund to the Main Highways Revenue Fund. The most important of these charges is that in respect of the Government subsidies on rates to local authorities, amounting for the year to £219,316. The expenditure from the Revenue Fund on highway maintenance actually showed a substantial reduction on the previous year, but this matter will be dealt with in detail later in this report. Operations under the Revenue Fund included the payment of subsidies on the maintenance of 10,419 miles of main highway, of which 6,641 miles are regarded as primary highways and 3,778 miles secondary highways. The expenditure from the Construction Fund for the year was £711,250, the figure for the previous year being £1,071,417. These figures indicate a severe curtailment of construction operations. The expenditure from the Construction Fund resulted in 130 miles 19 chains of highway being formed and widened, 128 miles 21 chains gravelled and metalled, and 159 miles 24 chains surfaced with bituminous materials or concrete. The year has been a notable one in regard to bridge construction, the total length erected being 11,175 lineal feet, a record for any year since the Board commenced operations in 1924. Engineering surveys were carried out over a length of 145 miles 30 chains of the highway system. In each of the past two annual reports the Board was able to record large increases in the expenditure on construction in the South Island. These increases were gratifying on account of the fact that during the first few years of the Board's operations construction work in the South Island lagged far behind similar work in the North Island. The operations during the year under review again show a satisfactory position in the South Island, the total amount spent on construction being £303,466, or 42-66 per cent, of the total construction expenditure. Last year the ratio of constructionmoney spent in the South Island was 33-96 per cent. It has always been the Board's policy to require as far as possible that all work shall be carried out under the contract system. In last year's report it was mentioned that there had been a tendency towards a reduction in prices, some very favourable tenders having been received for all classes of work, including formation, surfacing, and bridges. For the year under review it is necessary to record still further reductions in prices, but unfortunately in some cases tenders have been lowered to such an extent that acceptance of same would have meant almost certain insolvency for the contractors concerned. During the year the sum of £108,320 was expended in the Nelson and West Coast districts on the restoration of damage caused by the earthquake of the 17th June, 1929. The total expenditure on the restoration of main highways in these districts up till the 31st March, 1931, is £195,198. The severe earthquake which occurred in the Hawke's Bay District on 3rd February, 1931, involved the Board in further large liabilities. Up till the end of the financial year under consideration, the expenditure on restoration work in the Hawke's Bay area was £7,4-73. Further details concerning earthquake damage appear later in this report. It is noteworthy that the whole cost of these disasters to the Main Highways Board has so far been met from revenue, and not from borrowed, money. The Board's consistent policy during the past seven years of having a fairly substantial reserve in its Revenue Fund has been completely justified. Personal. Mr. A. E. Jull, one of the members representing the New Zealand Counties' Association and a foundation member of the Board, resigned his seat on the Board in September, 1930, to contest the Waipawa by-election, as a result of which he was returned as member of the House of Representatives for that district. Mr. Jull took a most active part in the proceedings leading up to the formation of the Main Highways Board, and was originally appointed a member on the 12th June, 1923. His long experience of local-authority law and administration enabled him to render very valuable services, and the successful functioning of the Board during its first seven years of office was due in no small measure to his efforts.

D.—l.

The vacancy caused by Mr. Jull's resignation was filled by the appointment on the 7th November, 1930, of Mr. W. Morrison, Chairman of the Waitotara County Council. Mr. W. A. Sutherland, who has acted as Secretary to the Board since 1924, resigned on the 30th June, 1931, and in his place Mr. Gγ. W. Knapp was appointed. Upon Mr. Sutherland's retirement the Board recorded in its minutes its great appreciation of the valuable services rendered by him during his seven years of office. Legislation. The Finance Act, 1930, contains the following clauses dealing with main-highway matters :— " 34. This Part of this Act shall be read together with and deemed part of the Main Highways Act, 1922 (in this Part referred to as the principal Act). " 35. (1) Section fourteen of the principal Act is hereby amended by repealing paragraph (a) thereof. " (2) Section sixteen of the principal Act is hereby amended by repealing paragraph (b) thereof. " 36. (1) As from the first day of April, nineteen hundred and thirty, interest at the rate of five per centum per annum shall, without further appropriation than this section, be paid out of the Main Highways Revenue Fund into the Consolidated Fund on the sum of one million two hundred and twenty-six thousand pounds, being the total amount heretofore appropriated out of the Public Works Fund and paid into the Main Highways Construction Fund, in terms of paragraph, (b) of section sixteen of the principal Act. " (2) The interest payable under this section shall be paid at such times as the Minister of Finance from time to time directs. " 37. (1) All subsidies payable to local authorities after the first day of April, nineteen hundred and thirty, in respect of general rates, pursuant to section nine of the Appropriation Act, 1916, or section seventy-two of the Municipal Corporations Act, 1920, shall, without further appropriation than this section, be paid out of the Main Highways Revenue Fund, and not out of the Consolidated Fund. " (2) Section nine of the Appropriation Act, 1916, and section seventy-two of the Municipal Corporations Act, 1920, are hereby accordingly respectively amended by omitting therefrom all references to the Consolidated Fund and substituting in every case a reference to the Main Highways Revenue Fund. " (3) All payments made to local authorities out of the Consolidated Fund on or after the first day of April, nineteen hundred and thirty, and before the passing of this Act, pursuant to the aforesaid sections or either of those sections, shall forthwith after the passing of this Act be recouped to the Consolidated Fund, without further appropriation than this section, out of the Main Highways Revenue Fund.

" (d) No appropriation shall be made out of the Main Highways Revenue Fund for the purposes mentioned in section thirty-nine hereof for any financial year after the financial year ending on the thirty-first day of March, nineteen hundred and thirty-one." Section 14, paragraph (a), of the principal Act provided for the transfer of not less than £35,000 per annum from the Consolidated Fund to the Main Highways Revenue Fund. Section 16, paragraph (6), of the principal Act provided for the transfer annually from the Public Works Fund to the Main Highways Construction Fund of a sum of not less than £200,000. It will be seen that both these provisions were repealed by section 35 of the Finance Act and are to be revived under section 40 on the Ist September, 1931. Section 36 of the Finance Act provides for the payment of interest from the Main Highways Revenue Fund in respect of the accumulated amounts which have been transferred from the Public Works Fund to the Main Highways Construction Fund since 1924, the annual amount involved being £61,300. Section 37 provides for the payment of subsidies on rates to'local authorities from the Main Highways Revenue Fund instead of from the Consolidated Fund, the amount involved being approximately £220,000 per annum. To enable the Board to meet the additional charges above mentioned without disorganizing its operations, the Government imposed a further Customs tax of 2d. per Imperial gallon on motor-spirits, the greater part of which under section 38 of the Finance Act was allocated to the Main Highways Revenue Fund. No payments have yet been made under the powers given in section 39 of the Finance Act, on account of the fact that, while the additional charges upon the Board's funds date from the Ist April, 1930, nevertheless, the additional Customs revenue commenced only on the 22nd July, 1930. As a result of discussion in Parliament arising out of the above legislation, the Right Hon. the Prime Minister announced that during the main session of 1931 a special parliamentary Committee would be set up to consider highway finance. That Committee has since been appointed, and is hearing evidence at the present time. Annual Review op Main Highways. The provisions of section 11 of the Main Highways Act, 1922, require that an annual review of highways shall be made by District Highways Councils, and, in turn, by the Board. Applications were received from local authorities for additional main highways, totalling approximately 1,200 miles, but as in the case of the previous year, the Board felt that it was unable to make any substantial increase in the declared mileage until it was able to gauge more accurately its financial liability in respect of the large mileage of secondary highways declared in 1928. The Board's attitude in this matter was more than justified by the enormous increase in the cost of maintenance of secondary highways which was recorded for the financial year ended the 31st March, 1930. The expenditure on the maintenance of secondary highways during the year under review shows a substantial reduction on the previous year, but how much of this reduction is due to a process of stabilization and how much to the prevailing depression, the Board is unable to gauge. The following adjustments and additions were made to the highway system during the year : — No. 1 Highway District. —Oakleigh-Waipu Main Highway : A length of 16 miles 60 chains was declared. This section of road forms an indispensable link between Whangarei and Auckland. The Public Works Department constructed the road to a modern standard in lieu of a railway, and upon completion of the work it was only natural that the section should be declared a portion of the main highway system. Whangarei-Dargaville Main Highway : An adjustment to the declared route was made on account of a deviation. No. 2 Highway District. —Great South Road: That portion of the Great South Road passing through the One Tree Hill Road District was revoked when the district was gazetted a borough. The length of highway involved, was 2 miles 75 chains. No. 3 Highway District. —Rotorua-Napier Main Highway : A length of 29 miles of this highway was revoked in order to permit of construction work being carried out by the Public Works Department, following upon the cessation of construction work on the Rotorua-Taupo Railway. No 6 Highway District. —Te Kuiti - Bulls (via Taumarunui) Main Highway : A newly constructed route between Okahukura Bridge and Taumarunui, a distance of 6 miles 65 chains, was declared as portion of the Te Kuiti -Bulls (via Taumarunui) Main Highway, and a length of 5 miles of the old route was revoked. The remaining section of 2 miles of the old route between Okahukura Bridge and Taumarunui was incorporated with the Taringamotu Valley Road as a secondary highway. No. 9 Highway District. —Porirua - Titahi Bay Main Highway : A length of 3 miles of this road was declared. No. 10 Highway District. —Martinborough-Masterton (via Gladstone) Main Highway : An additional 24 chains of road was declared as a result of an alteration in the boundary of the Masterton Borough. No. 15 Highway District. —Beach Road - Hakatere Main Highway : A length of 7 miles 60 chains was declared. Lauriston-Barrhill Main Highway : A length of 5 miles 19 chains was declared. Arowhenua-Fairlie, via Pleasant Point and Middle Valley Main Highway : A connecting-link of 2 miles 64 chains in the Pleasant Point Town District and the Levels County was declared. No. 16 Highway District. —Junction near Wedderburn - Moa Creek School Main Highway : A length of 7 miles 70 chains was declared as an extension. Alterations to Highway Districts. To assist in administration, and with the concurrence of the Highways Councils concerned, the Waitemata County was transferred from the No. 1 Highway District to the No. 2 Highway District on the 31st March, 1931. Similarly, on the 2nd June, 1930, the Waitaki County was transferred from the No. 15 Highway District to the No. 16] Highway District.

Finance. The actual contributions to the Board's Kevenue Fund from external sources for the year 1930-31 amounted to £1,745,536. The tabulation below shows how this amount is made up. The income from similar sources during the previous five years is also shown : —

The elimination of the first item in the table for the year 1930-31 has already been explained, the effect of the relevant amending legislation being that the whole of the Board's revenue is now derived from special motor - taxation. With regard to the proceeds of the Customs tax on tires and tubes, the figures again reveal a substantial reduction, the receipts being £94,000 less than in 1925-26, when the number of vehicles registered was about 43 per cent, of the present number. To indicate the enormous reduction in another way, the tire-tax in 1924-25 amounted to £1 12s. sd. per motorvehicle as compared with lis. 3d. per motor-vehicle in 1930-31. These figures indicate how unreliable the tire-tax is as a form of revenue for a road-controlling authority. In the above table the proceeds from the motor-spirits tax for 1930-31 show a large increase on the previous year. The chief reason for this increase — namely, the imposition of an additional customs duty "of 2d. per Imperial gallon of motor-spirits —has already been mentioned. The total amount of petrol-tax collected by the Customs Department for the year was £1,417,294, and of this amount £102,844 was refunded to persons entitled to exemption under the Motor-spirits Taxation Act. After charges for collection and for making refunds were deducted, the balance available for distribution amounted to £1,300,050, of which £1,219,209 was credited to the Main Highways Revenue Account, and £80,841 was paid to cities and boroughs of a population of more than six thousand, the allocation being made on a population basis. For the year ending 31st March, 1931; the expenditure under the Revenue Fund was as follows : — Expenditure. £ North Island .. .. .. .. ■■- . • •• 516,840 South Island 355,737 Administration charges .. .'*'■ .. .. .. .• 38,449 Commission paid to Post and Telegraph Department for collection of motor-registration and license fees and registration of change of ownership .. .. .. .. .. .. ■ • 20,901 Subsidies on rates of local authorities (Finance Act, 1930) .. .. 219,316 Miscellaneous payments, including recoupment of interest on loans to Consolidated Fund and reserve for redemption of main-highway securities .. .. .. . • ■ • • • ■ • 234,897 Total £1,386,140 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.

A comparison of the contributions of local authorities towards the cost of maintenance of mam highways shows considerable reductions this year compared with the figures for last year. Towards the cost of maintenance of primary highways last year the local authorities found the sum of £273,063, whereas for the year under review the corresponding amount was only £235,688, or a reduction of over £37,000. On secondary highways it will be seen from the above table that the local authorities found £82,151, whereas for the previous year the amount was £102,786, a reduction of over £20,000. The total reduction in the local authorities contribution on the whole highways system was therefore about £58,000. The following tabulation shows the amount which has been provided by the Board and the local authorities for expenditure on both construction and maintenance of main highways during the seven years 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 by the Board 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 m percentages of the Dominion totals : —

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, registration and license fees for the year ending 31st March, 1931, has been made between the two Islands in proportion to the number of mo tor-vehicles registered in each Island on that date. As explained in the last two annual reports, no statutory provision exists requiring an apportionment of the proceeds from the petrol-tax between the two Islands. The Board is of the opinion that the most equitable method of distribution of this tax is on the basis of the consumption of inotorspirits in each Island. As in previous years, the Board obtained figures from oil companies, and these figues show that during the calendar year 1930 approximately 67 per cent, of ttte motor-spirit imported was consumed in the North Island, and approximately 33 per cent m the South Island, as compared with 69 per cent, and 31 per cent, respectively for the previous calendar year. No adjustment has been made on these percentages to take account of rebates, because definite information is not available, and in any case it appears probable that the rebates in each Island will bear the same relative proportions as the petrol consumed. Moreover, the proportion of rebates is so small that a verv Considerable error in their proportions would not materially affect the proportion of the totals. In making the apportionment the interest and redemption reserve charges on moneys borrowed for construction work in each Island have been charged, against the revenue allocation to each Island, and other adjustments in connection with interest on accumulated balances have been made The subsidies on rates to local authorities paid from the Main Highways Revenue Fund under the authority, of the Finance Act, 1930, have also been taken into account in the apportionment. On the assumptions riven above, the balances to the credit of the North Island and South Island respectively on ffilst March, 1931, were £193,409 4s. 3d. and £190,307 19s. 10d.

Last year by far the greater proportion of the balance in the Revenue Fund stood to the credit of the South Island. The position has changed on account of three factors : (1) The reduction in maintenance expenditure during the past year has been proportionately much greater in the North Island than in the South Island. (2) The expenditure on construction in the South Island during the past year has been greater proportionately than in any other year since the Board commenced operations : this means that a greater proportion than usual of the money transferred from the Revenue Fund to the Construction Fund was spent in the South Island. (3) Much greater expenditure for the year on earthquake damage in the South Island than in the North Island. A permanent transfer of the sum of £300,000 was made from the Revenue Fund to the Construction Fund during the past financial year, this transfer being in accord with the policy announced at the time of the passing of the Motor-spirits Taxation Act. For the year ended 31st March, 1931, the expenditure, including administration charges, &c, under the Construction Fund was as follows :— Expenditure. £ North Island .. .. .. .. 407,784 South Island .. .. ..

D.—l

The amount provided by local authorities towards the cost of construction works on the original highway system shows a reduction of £39,000, as against a reduction of £19,000 in the previous year. On construction work on secondary highways the local authorities found £13,000 less than in the previous year, so that on the whole highway system the amount provided by local authorities for construction has dropped £52,000, as compared with the previous year. The percentage of construction-cost provided by the Board has increased from 70 per cent, in 1924-25 to 83 per cent, for 1929-30 and 81 per cent, for 1930-31. Maintenance. During the first half of the year the main highways generally were kept up to standard as regards maintenance. During the latter half of the year, however, there has been evidence that the local authorities have curtailed maintenance work to some extent, principally, of course, on account of the depression and the difficulty in collecting rates. When the final figures for the year were obtained, it was found that the curtailment in expenditure had been most marked. The amount of benzine imported into the country is probably a very fair indication of the volume of the Dominion's motor traffic. The gross importations of benzine since 1926 are as follows :— Gallons. Gallons. ]926 .. .. .. •• 44,800,000 1929 .. .. .. .. 62,400,000 1927 . • 48,000,000 1930 .. .. .. .. 68,300,000 1928 .. .. .. •• 54,500,000 In the same period the total expenditure on maintenance of primary highways, including local authority contributions, but excluding special earthquake damage, has been as follows : — £ £ 1926-27 .. 715,111 1929-30 .. .. .. .. 990,953 1927-28 .. .. •• •• 792,646 1930-31 .. .. .. .. 806,366 1928-29 .. 832,618 From the above figures it will be seen that the total expenditure on maintenance of primary highways in 1927-28 was practically the feme as the expenditure in 1930-31, yet in the latter year the traffic was 40 per cent, greater than in 1927-28. It will also be seen that in the year under review the primary highways received £184,000 less than they did in the previous year, in spite of the fact that the traffic appreciably increased. It is manifest therefore that the highways were not adequately maintained during the past year. The fact that the local authorities curtailed their own expenditure resulted in lower claims upon the Board's funds, with the effect that the Board found itself with approximately £130,000 more in its Eevenue Fund at the end of the year than it anticipated. The anomalous position has therefore arisen that the roads have had less money than they needed and the Board has a somewhat larger surplus than it deems necessary. Since the figures have become available the position has been carefully considered and, with a view to bringing up the maintenance expenditure to the amount which is obviously necessary taking the volume of traffic into consideration, and at the same time relieving the local authorities during a period of economic stress, the Board on the 19th August, 1931, decided to increase the subsidy for ordinary maintenance from £2 for £1 to £3 for £1. The average cost of maintenance per mile per annum since 1924 on the primary system is as follows :— £ £ 1924-25 •• •• •• 51-7 1928-29 ~ .. .. •■ 125-2 1925-26 73-2 1929-30 .'• 151-2 1926-27 111-9 1930-31 121-4 1927-28 119-9 Again, it will be seen that for the first time on record the maintenance cost of the primary highways has been substantially reduced. With regard to secondary highways, a total length of 3,778 miles was maintained at an average cost of £71 per mile, the figures for the two previous years being : 1928-29, £55-5 per mile, and 1929-30, £88-5 per mile.

Construction. During the past seven years the Board has been responsible for the closing-up of a large number of unmetalled gaps in the arterial road system. One of the most important links remaining in the Dominion has been that between Auckland and the North Auckland Peninsula. During the past three years special attention has been devoted to this work and considerable progress achieved. In last year's statement it was possible to report that surfacing-work had reached the Township of Warkworth. This year it is gratifying to record that a temporary connection to the Far North was established before the present winter. This connection, being by a devious route via Wharehine is regarded as a temporary one only, but, nevertheless, is sufficient to allow light notor traffic to proceed to Whangarei and other northern centres under all-weather conditions. Surfacing-work on the more heavily trafficked sections of main highway, principally adjacent to the main centres of population, has proceeded satisfactorily. In the South Island, in particular, excellent progress has been made. As mentioned previously, the year has been a most notable one as regards bridge-construction. Although the total expenditure on all construction was substantially less than in the previous year, nevertheless, the length of bridges completed is a record since the Board commenced operations. In the fifth annual report, to give an idea of the bridge programme immediately ahead of the Board, a list of important structures commenced or requiring to be put in hand in the next year or two was shown. The list included thirty-two important structures, all of an estimated cost of over £4,000. The present position is that nineteen of these structures have been completed, five are in hand, and the remaining eight have not yet been commenced. Some of the largest structures which have been completed in the year under review are as follow : Mangaoporo Bridge, consisting of four 80 ft. truss spans; the Awatere Bridge, consisting of plate girders and concrete deck, and having three 60ft. spans and one 35 ft. span ; the Mangatewai-nui Bridge, a reinforced-concrete structure, comprising two 40 ft. and three 50 ft. spans ; the Manawatu Gorge Bridge, a handsome concrete structure, comprising four 80 ft. arch spans and six short spans ; the Aorangi Bridge, a reinforced-concrete structure, 576 ft. in length ; the Kuamahanga Bridge, consisting of eleven 40 ft. spans of reinforced concrete ; Kokotau Bridge, also a reinforced-concrete structure, consisting of eight 45 ft. spans ; the Newton River Bridge, a steel-truss structure, 180 ft. in length ; the Little Wanganui Bridge, consisting of six 40 ft. spans ; the Ahaura Bridge, 720 ft. in length ; McDonald's Creek Bridge, 200 ft. in length ; the Waimakariri River Bridge, consisting of plate girders with a concrete deck, and comprising twenty-nine spans of 40 ft.; the Selwyn River Bridge on the Darfield-Arundel Main Highway, a reinforced-concrete structure, 300 ft. in length ; the Ashburton River Bridge, a reinforced-concrete structure, 1,120 ft. in length, furnished with a roadway 22 ft. in width and a footpath 6 ft. in width ; the Clutha River Bridge, at Albert Town, consisting of six 50 ft. spans in reinforced concrete ; and the Aparima River Bridge, at Riverton, a reinforced-concrete structure 440 ft. in length. Railway-crossing Elimination and Protection. Principally on account of the financial situation of the Railways Department, only one railwaycrossing elimination was proceeded with on the main highway system during the year. This elimination is situated on the Auckland-Wellington Main Highway in the vicinity of the Borough of Waitara. The bridge structure has been completed and the approaches are now in the process of construction. The Railways Department during the year erected flashing lights and other protective signals at a number of crossings on the main highways, the Main Highways Board undertaking to find half the cost of both the installation and the future maintenance. Advances to Local Authorities. Under section 2 of the Main Highways Amendment Act, 1926, which authorizes the Board to advance moneys by way of loan to local authorities for highway purposes, a sum of £18,190 was advanced, making a total to the 31st March, 1931, of £57,377. All loans are made on the instalmentrepayment system, the local authorities being required to make equal annual payments, which include interest on the amount for the time being outstanding and part repayment of principal. The principal repaid to the 31st March, 1931, amounted to £7,213, leaving a balance outstanding of £50,164. The powers vested in the Board under the above-mentioned clause have been most beneficial, and are primarily responsible for the excellent progress made in the past three years in the South Island. Traffic-control. As mentioned in last year's report, the Board suggested to local authorities that certain groups should combine for the purpose of efficiently administering the traffic regulations. In cases of approved joint schemes the Board indicated that it would subsidize the wages and expenses of a Traffic Inspector on a pound-for-pound basis. A number of local authorities have taken action in this direction,.and schemes have already been approved and are in operation in the following areas : — — Hamilton Group, including Waikato County, Waipa County, Otorohanga County, Raglan County, Ngaruawahia Borough, and Huntly Town District. Thames Group, including Thames County and Ohinemuri County. Rotorua Group, including Rotorua County and Rotorua Borough. Gisborne Group, including Cook County, Waikohu County, Uawa County, and Waiapu County. Napier Group, including Hawke's Bay County, Woodville County, Weber County, Dannevirlce County, Waipukurau County, Patangata County, and Waipawa County.

In order to assist those reponsible for the submission of schemes for highway improvement the Board issued early in 1930 its second bulletin entitled " Typical Specifications with Introductory Notes on Mam Highway Standards and Design." The publication comprises seventy-eight pages and is furnished with a comprehensive index. Copies of the bulletin were supplied free of charge to all local authorities m the Dominion, while to meet the public demand, copies were made available for sale at a nominal charge. The skeleton specifications issued by the Board in 1925 were withdrawn. Sixth International Road Congress. The New Zealand Government was invited by the United States Government to send an official delegate to the Sixth International Road Congress held at Washington, D.C., from the 6th October to the lltli October, 1930. Mr. A. Tyndall, Highways Engineer, was appointed, and left New Zealand on the 26th August, 1930, returning on the 12th January, 1931. While in North America many »reat courtesies were extended to the representative from New Zealand by the Chief of the Bureau of Public Roads, Mr. T H Mac Donald, the officers of the Federal Government associated with him in Washington and also by the State highway officials with whom he came in contact both in the USA and Canada' Without a single exception these officials did everything in their power to supply any information at their disposal, as well as to make special arrangements to enable the delegates to view numerous works under construction. Special tours lasting for some seventeen days, held under the auspices of the Highway Education Board, proved most interesting and beneficial. Upon his return, Mr. Tyndall furnished a comprehensive report to the Government and to the Board. RoUGHOMETERS. One of the features of a highway always closely observed by road-users is the smoothness or ridingquahty of the road-surface. A rough surface gives rise to effects unpleasant to the passenger and detrimental to the vehicle. Smooth surfaces mean greater mileage with less fatigue, with less damage to the contents of the vehicle, and with lower operating-costs for the vehicle. Thus, as far as the user is concerned, the question assumes a very considerable economic aspect. On the other hand the highway engineer is vitally interested in building and maintaining smooth roads on account of the direct effect of surface-roughness on the life of the pavement. The research of the past few years has clearly indicated that road-roughness produces impact, and impact contributes to the early deterioration of any type of road-surface. So convincing has been the evidence of this fact, that many highway engineers have expressed the belief that smoothness is the most important quality to be sought m road-surfaces. The appreciation of the importance of surface-smoothness has resulted in the development of a number of mechanical appliances for the measurement of same. A comparatively simple and efficient instrument for determining relative roughness was devised some five years ago by the Bureau of Public Roads in the United States of America, and is known as the roughometer It Has been adopted by a number of Highway Departments in different parts of the world and its use in many places has resulted in considerably improved standards in the riding qualities of new pavements. The instrument is fitted to an ordinary motor-car, and actually measures the total average accumulated compression of the two front springs of the vehicle in inches per mile of distance travelled The Main Highways Board has purchased two of the instruments, and during the forthcoming season they will be fitted to motor-cars and used in determining relative roughness of a number of recently constructed pavements. ■ Magnetic Truck. Investigations have shown that there is considerable economic loss annually to the road-user in the way of damage to tires by punctures and cuts caused by iron and steel nails and other metal fragments. To deal with the problem there have been developed in other countries, notably the United States of America motor-trucks fitted with special electro-magnets. The trucks patrol the highways at a comparatively slow speed, the magnets being suspended within a few inches of the road-surface Surprisingly large quantities of iron and steel scrap are usually gathered, and the beneficial results which have followed the use of the devxces have been most noticeable. The Board proposes to try out the scheme m this country, and with this in view a special magnetic truck is at present being assembled. Progress Report.
