REPORT. In the Surveyor-General's report for the year 1912-13 it was stated that the area surveyed during that year showed an excess over that surveyed the previous year. A like result is apparent in comparing the work performed this year with that performed last year. The area triangulated shows an increase of nearly 90,000 acres, and the rural an increase of about 140,000 acres. There is, however, a decrease in the Native Land Court surveys of about 96,000 acres, and m Maori Land Board surveys of 4,500 acres. It is very satisfactory to find that the cost per acre in all classes of survey is considerably less than it was last year. This is especially noticeable in the case of rural surveys by staff surveyors, where the price has fallen from 2s. last year to Is. 7d. this year. This tends towards showing that the staff surveyors have been pushing on their work with commendable zeal. The following table gives a summary of the principal classes of work completed during the year :—

Table A.

Triangulation. In the secondary tri angulation which is being carried out under the immediate control of the Head Office the design of the whole network over the Auckland District (covering an area of 28 000 square miles) has been completed, under the direction of Mr. Langmuir, at a total cost to'the 31st March of £3,208 15s. 6d. This cost includes the cost of the launch " Vanora," £625 18s. Bd.; first cost of signals. £488 11s. lid.; and office-work, £38 4s. 10d. A position for the final base for the North Island has been located, and repairs effected to old trig, stations included in the design. Computations have also been carried on as detailed in report by the Chief Computer. Minor triangulation has been restricted to such work as was necessary for the control of settlement surveys, and was carried out by staff surveyors under control of the Chief Surveyors. Auckland shows 37.300 acres; Hawke's Bay, 13,500 acres; Nelson, 181,583 acres; and Wjestland, 10,000 acres : a total of 242,383 acres, at an average cost of l'34d. per acre. Mr. Climie has undertaken triangulation in connection with the coupling-up of Mount Cook and Hector Observatories, and in his report will be found some very interesting information that he has searched out from old records. ' Standard Surveys. Work has been continued in the Auckland District by Mr. Langmuir, and under his direction by Mr. H. M. Kensington, and during the year the plans of the standard survey of Parnell have been completed, the total cost of the work to the Department being £783 os. 7d. It was

a difficult and somewhat costly work, owing to the irregularity of the streets and the unsatisfactory nature of the old surveys, which involved a large amount of searching and other office-work. The Otahuhu standard survey has also been completed, at a total cost of ,£304 18s. 2d. Mr. C. A. Mountfort has been occupied on standard surveys of Gonville, Nelson, and Wanganui. Mr. Neill has completed the field-work of the first contract for the standard survey of Dunedin, and in January started the field-work of North-east Valley under the second contract with the City Corporation. The plans are being steadily prepared by Mr. Saunders. Settlement Surveys . Under the heading of rural surveys 552,604 acres have been surveyed, at an average cost of Is. 7fd. per acre. Of this, 101,288 acres are credited to Auckland, 98,371 acres to Marlborough, 82,767 acres to Nelson, 82,208 acres to Canterbury, 48,535 acres to Taranaki, 42,373 acres to Hawke's Bay, 30,785 acres to Southland, 26,163 acres to Wellington, 20,385 acres to Westland, and 4,067 acres to Otago. To arrive at the area made available for settlement there should be added to the above 1,775 acres of village and suburban lands and 13,213 acres of Maori Land Board surveys, the total area thus being 567,592 acres. Included in this are the areas of estates purchased by the Crown under the Land for Settlements Act, amounting to 200,886 acres, and distributed as follows: Marlborough, 85,647 acres; Canterbury, 66,523 acres; Southland, 25,710 acres; Nelson, 13,171 acres; Hawke's Bay, 6,236 acres; Otago, 1,425 acres; Auckland, 1,421 acres; and Taranaki, 753 acres. The area thus prepared for settlement during the past year exceeds that of the previous year by 137,273 acres, and constitutes a record result for any one year since 1906. At the close of the year there were in the hands of the surveyors 778,059 acres of rural land (including land for settlements, village and suburban), 585 acres of town sections, and 359 miles of road. A good deal of the field-work of this has been done, and it is intended that the mapping shall be brought up to date during the months of July and August ensuing, so that a large area will be available for opening in September next. Native Surveys. The area of Native Land Court surveys completed during the past year by staff surveyor* was 29,258 acres, and by licensed surveyers 528,141 acres; and, as mentioned in connection with settlement surveys, 13,213 acres .'of Maori Land Board surveys —in all, 570,612 acres. There is at present on hand for survey during the ensuing year 817,716 acres of this class of land, in the field-work of which considerable progress has already been made. Gold-mining Surveys. Twenty-seven applications were surveyed, totalling 1,573 acres, of which staff surveyors, mostly in Auckland, surveyed 825 acres at a total cost of ss. per acre, the remainder being laid off by private surveyors nominated by the applicants. Inspection of Surveys. Inspection of surveys have from time to time been made by the Inspecting Surveyors, by Chief Surveyors, or by District Surveyors under their direction. Those inspections show that while nearly all of the staff and licensed surveyors are turning out first-class work, there are a few whose work cannot be depended on, hence the necessity for field-checking. I am of opinion that all such inspection-work should be done by officers immediately under the control of the Surveyor-General, and that, if possible, every surveyor's work should be checked once a year. Operations, 1914-15. There is not likely to be any cessation in survey-work during next year. In addition to the secondary-triangulation work which will still be carried on, there are, as already stated, now on hand 180 square miles of minor triangulation, 778,059 acres of settlement land, 585 acres of town land, 817,716 acres of Native lands, and 359 miles of roads. There is a probability of the purchase of a number of estates under the Land for Settlements Act, and, in Otago especially, where work has been somewhat slack, there, are several large pastoral runs suitable for subdivision the leases of which will expire next year or the year after, and which will require survey. The matter of providing small fruit-farms in Central Otago will also involve extra surveying-work. Taking it altogether the coming year will tax the strength of the present field staff to the utmost, and it may be necessary to resort more freely than in the past to the contract system. Standard-survey work will also have to be kept going. The value of such work is getting to be more and more appreciated, and provision will have to be made for the survey of many of the smaller towns as soon as that of the cities has been completed. The standard survey of rural districts, where, on account of the flatness of the ground, the erection of buildings or growth of plantations has, by obstructing the lines of sight between the trig, stations, rendered the triangulation useless for initial and check bearings, is a work the urgency of which becomes more apparent every year. Surveyors Board. The work of this Board during the past year was principally of a routine character. Acting in conjunction with the six Australian Boards it conducted examinations of candidates for surveyors' licenses in September, 1913, and March, 1914. At the September examination twentyone candidates sat. Of these, five passed the whole examination, and nine completed the examina-

tion, having passed in some of the subjects previously. At the March sitting ten candidates presented themselves, and of these four completed. The papers for the September examination were set by the New Zealand Board, while those for the March examination were set by the Tasmanian Board. Revised examination regulations were gazetted on the 7th August, 1913, and copies are available for distribution. The Board records with regret the deaths of the following surveyors reported during the year : James Orme Barnard, Auckland; Percy Bedlington, Whangarei; William Lowthian Forster, Auckland; Archibald Campbell Turner, Tauranga; Edwin James Campion, Gisborne; Captain James Dudley R. Hewitt, Palmerston North; George Mackenzie, Queenstown; William Archer Nalder, Briglitwater. Tidal Survey. During the year the work of tide-predicting has been carried on under the direction of Mr. C. E. Adams, Chief Computer. This work has comprised the predictions from the harmonic tidal constants already obtained of the times of high and low water for the ports of Auckland and Wellington, and the obtaining of the harmonic constants for Dunedin from an harmonic analysis of the hourly ordinates of the automatic tide-gauge records at that port." This work has kept two assistants going steadily. In addition to the principal calculations a considerable amount of check-computation work has been done to ensure accuracy, and the final predictions have repeatedly been checked by comparison with the latest available tide-gauge records, the results being most satisfactory and testifying to the care and accuracy with which the computations have been made. A full report by Mr. Adams will be found among the appendices, in which report he gives a schedule of the harmonic tidal constants for Dunedin from hourly ordinates during the year Ist July, 1911, to 30th June, 1912. In the report will also be found a reference to a tidepredicting machine on the designing of which Mr. Adams, in conjunction with Mr. W. S. La Trobe, M.A., has spent considerable time. Magnetic Observatory. Under the direction of Mr. H. Skey the work of the Magnetic Observatory at Christchurch has been carried on with the usual efficiency. During the year, in addition to the routine work, a large amount of data from past observations has been put into form for publication. The Milne seismograph No. 16 has been kept in continuous operation, and has recorded seventy-four earth-movements. The Adie mugnetographs have also been in almost constant and meteorological observations have been made and published daily. Among the appendices will be found Mr. Skey's report, illustrated by diagrams, which contains deductions as to the times of maxima and minima of declination and horizontal force and other matter very interesting to the student of earth magnetism. Hector Observatory. The principal work carried on at this observatory is the observing for, recording, and signalling the standard time for the Dominion. Though .the observatory is under the control of the Department of Internal Affairs, this important work has been carried on by Mr. C. E. Adams, Chief Computer in this office, who also fills the position of Government Astronomer, and who takes a very keen interest in the work. Under his direction also computations have been made in respect of pendulum-work, longitude of base stations, and time-signalling in connection with the Antarctic Expedition under the late Captain Scott. Conclusion. As I did not take up my present position as Surveyor-General till after the end of the financial year under review I have not entered into detail in this report. The usual full reports from the Chief Surveyors, Chief Computer (tidal survey, &c), Director of the Magnetic Observatory, and others, with illustrative diagrams and tables, will be found as appendices. My predecessor in this office, Mr. James Mackenzie, now Under-Secretary, who controlled the surveys of the Dominion for the period reported on, desires, on moving on to his higher office as head of this Department, to record his appreciation of the loyal and valuable support he received from both indoor and outdoor officers of the Department during the two years he held the position, and also wishes to thank the private members of the profession for their hearty co-operation during his term of office. E. H. Wilmot, Surveyor-General.

APPENDICES.

APPENDIX I.—SURVEYS.

AUCKLAND. Minor Triangulation. —A staff surveyor executed 37,300 acres, costing o'9sd. per acre, in West Taupo County. Topographical. —l3,2Bo acres, costing l'6sd. per acre, by staff surveyors, and 6,072 acres at r-Bd. per acre, by a contract surveyor, for the Native Land Court, were surveyed during the year. Sural. —Staff surveyors executed 87,239 acres at 2'255. per acre, and contract surveyors 14,049 acres at 2'535. per acre, and 14,555 acres paid for privately, making a total for the year of 115,843 acres. Village and Suburban. —The staff surveyed 429 acres in 38 subdivisions, costing 5"375. per acre. Town Sections Survey. —Staff surveyors surveyed 145 acres in 320 sections, costing 2T295. per acre Native Land Survey. —The staff surveyed 27,628 acres in 103 subdivisions, costing 18'24d. per acre; contract surveyors 329,029 acres in 1,596 subdivisions, costing 19'26d. per acre, and 11,202 acres in 2 subdivisions, the cost of which is not yet available: making a total of 367,859 acres in 1,701 subdivisions. Of this total 4,487 acres in 8 subdivisions by a staff surveyor were for the Maori Land Board, the balance being for the Native Land Court. Gold-mining Survey. —rContract surveyors executed 749 acres in 8 claims at 4'545. per acre, and 106 acres in 7 claims the cost of which is not available. Roads, &c. —The staff surveyed 63"14 miles at £23'14 per mile, and contract surveyors T25 miles at £16 per mile, and 5/75 miles the cost of which is not yet available. Other Work. —This work includes the usual large number of miscellaneous and scattered isolated surveys, reports, inspections, road-engineering surveys, &c. Inspections. —The inspections of surveys showed that generally satisfactory work is being done, but in some cases private surveyors have shown want of care, especially in redefining old boundaries, and have evidently allowed irresponsible men to do field-work without proper supervision, and have merely signed the plans themselves. Contract Surveys. —Contract surveyors have on hand 6,878 acres of Crown land, 213,080 acres of Native land, and 27 miles of roads. Office-work. —Land Transfer Branch examined and approved 770 plans of 6,886 allotments, containing 137,380 acres, and 1,409 traverse sheets; 156 tracings prepared and 20 plans compiled. Mr. Harding, of the Land Transfer Office, endorsed 3,452 plans on certificate of title, &c, and prepared 21 plans. Fifty-nine plans have not yet been examined. Native Land Surveys Branch : 322 plans have been examined and approved, comprising 305,951 acres in 1,501 subdivisions; 80 plans have been compiled; 280 tracings made for the Valuation Department; 357 tracings for posters and surveyors, &c, prepared; 1,546 Court orders, &c, endorsed on certificates of title; 213 applications to Wellington for financial authority, and 266 authorities to sxirvey issued. Six Native Land Courts attended, and £752 os. 9d. survey liens collected, and 651 charging-orders obtained. ,£16,720 Bs. 3d. survey liens collected during the year. The Native Land Amendment Act, 1913, is giving this branch considerable extra work compiling plans and in roading the Native blocks. Statutory Plans and Roads Legalization Branch : 269 plans were examined and approved taking and closing 280J miles of road; 902 acres of reserves for various purposes, and taking 10 miles for railways; 17 plans were compiled; 240 tracings made; and 267 plans entered on records. Computing Branch : 235 plans, containing 168,763 acres of Crown land in 1,123 sections, were examined and passed; 19 mining plans and 1 residence-site were examined and forwarded to the Wardens, also 40 old mining plans were reported on; 686 traverse sheets and 53 connecting triangle sheets were examined; 492 chain lengths of surveyors' steel tapes were tested and certificates issued; 1,175 tracings for posters, selectors, surveyors, &c, were prepared. Applications for loans amounting to £40,605 on 19 blocks, containing 62,202 acres, were prepared. General: Fees collected, £285 19s. 9d.; 4,828 plans were endorsed on Crown grants, &c. The total number of plans examined and approved by this office was 1,616; plans compiled, 117; tracings, &c, made, 2,580. Proposed Operations, 191^—15. —Thirty-two surveyors (24 staff and 8 temporary) have on hand 212,617 aores of Crown land, 228,707 acres of Native land, and 200 miles of road surveys. In addition to the above the larger areas of Crown land and new purchases proposed to be surveyed for selection are as follows, arranged in counties : Mangonui, 8,700 acres national endowment; Whangaroa, 2,600 acres; Bay of Islands, 9,800 (4,400 national endowment) acres; Hokianga, 9,200 (3,375 national endowment) acres; Whangarei, 4,950 (2,200 national endoment) acres; Hobson,

1,550 acres national endowment; Otamatea, 3,684 (1,820 national endowment) acres; Rodney, 1,030 (760 national endowment) acres; Waitemata, 4,440 (64(5 national endowment) acres; Raglan, 2,800 (850 national endowment) acres; Waikato, 5,000 acres national endowment; Waitomo, 6,850 acres; Awakino, 11,178 acres; West Taupo, 12,600 acres; Coromandel, 20,000 acres; Thames, 10,000 acres; Ohinemuri, 5,000 acres (1,650 acres land for settlement); Tauranga, 11,000 (6,200 national endowment) acres; Rotorua, 4,646 (2,646 national endowment) acres; Matamata, 6,700 acres land for settlement; E'ast Taupo, 10,000 acres; Opotiki, 5,000 acres; Whakatane, 3,000 acres. There will also be a considerable area set free for settlement, for which provision will be made, as soon as the report of the Kauri-gum Royal Commission is complete. The applications for areas under Hauraki pastoral lease show a large increase under the improved conditions, and I propose to detail an extra surveyor to meet this demand. Accounts. —The Accountant reports that the number of vouchers which passed through the books for the y r ear amounted to 3,150, for a total expenditure of £97,010 16s. 9d., which includes credit transfer vouchers for work done for other Departments, amounting to £22,287 4s. Bd. Transfers, &c. —The field staff has been increased by seven transfers and appointments, while one surveyor resigned and one transferred from the district. This includes the appointment of an additional Field Inspector. Owing to the demands of the public, increased office staff is required to keep arrears from unduly increasing and to fill vacancies caused by resignations. Conclusion. —1 have to thank the staff for their loyal efforts to cope with the heavy work. All officers, both field and indoor, have done their best to maintain the high standard of the Survey Department. H. M. Skeet, Chief Surveyor.

HAWKE'S BAY. Minor T riangulation. —Preparations are now being made to extend the major triangulation from the Auckland District over the northern part of Hawke's Bay, and until this is done to form an accurate basis it would not be advisable to execute any more minor trig, work than that actually required to control sectional surveys. The present minor trig, work is generally of a very poor standard, and, being on several different measurements-, is incapable of being brought into harmony without revision or extension. An area of 13,500 acres of this class of work was executed during the year for the purpose of controlling sectional surveys, as mentioned above. Topographical Survey for Selection. —Although nothing has been returned under this heading, a large area has been done by staff surveyors as a preliminary to the subdivision of Crown and Native blocks. This has been found very useful in presenting a more detailed knowledge of much country of which very little was known before except in a general way. The cost in each case has been included in the area under subdivision. Rural. —The work executed during the year consisted principally of five blocks situated in the Tahoraite, Waikareinoana, Waiau, Patoka, and Maungaharuru Survey Districts, and comprised an area of 42,373 acres at an average cost of l's7s. per acre, all by staff surveyors. The cost per acre is a little higher than usual owing to the cost of the Hukanui Block, in Waikaremoana and Waiau districts, being so high : this was due to the difficulty in working the heavy bush country and the excessively bad weather experienced during the survey. Staff surveyors have in hand under this heading on the 31st March, 1914, 109,162 acres, but the field and plan work of a large portion of this area—viz., Springhill, Kaiwaka, and Otawhao Blocks—is nearing completion. Town Surveys. —Although no area is returned under this heading for the year, 2 blocks subdivided into 50 lots, 1 lot in the Town of Napier and 49 lots in the Borough of Hastings, for workers' dwellings, are about complete. Village and Suburban. —Under this heading 4 lots were laid off, containing 97 acres, at a cost of 3'l7s. per acre. Roads. —Six Crown plans were received, giving a total length of 34 miles 51 chains : these are miscellaneous, and not a part of reading laid out in connection with land for settlement. Native Surveys. —The total area surveyed during the year amounted to 79,910 acres, in 743 subdivisions. Of this area the staff surveyed 4,726 acres into 71 allotments, at a cost of 22'33d. per acre (made up principally of the Otawhao, Omahu, Paramu, and Manutahi Blocks), while private surveyors completed 75,184 acres, containing 672 allotments. Field' Inspections. —During the year 23 field inspections of staff and private surveyors were carried out by Messrs. Brook, Farnie, Walshe, and Atkinson, and the works examined were found to be generally satisfactory. Mr. Brook carried out the work of inspection of the work of staff surveyors. Work in Progress. —The following are the principal surveys in hand: Kaiwaka Block, 14,483 acres, and Pohue—Tuitira Road and extension in connection with same; Marangairoa Native Block, 18,000 acres, and road access in connection therewith; Otawhao Block, 5,213 acres; Crown lands on Tutaekuri River-bed, 2,000 acres; Waipaoa Block, 16,785 acres; subdivision of Crown lands at Lake Waikaremoana, 6,000 acres; subdivision into 49 allotments of 30 acres for workers' dwellings at Hastings; subdivision into lots of 4 acres for workers' dwellings at Pakowhai Settlement, near Hastings; Springhill Estate (land for settlements), 6,236 acres; 6 Native surveys, containing 1,4-60 acres, in Waipiro, Mata, and Tokomaru Survey Districts; Mangawhariki Native Block, 7,145 acres; Wharekahika Native Block at East Cape, 42,000 acres. In the majority of cases the field-work in the above surveys has been completed and the plan-work well forward; while in others, such as Waipaoa and Wharekahika Block, the field-work is about three-eighths through.

Proposed Operations, 191J/.-15. —Mr. Thomas Brook, Inspecting Surveyor, will carry out field inspections of staS and private surveyors, and miscellaneous surveys, in addition to his duties of General Supervisor in the Gisborne office, and such other work that may be relegated to him from time to time. Mr. E. H. Farnie, District Surveyor, apart from the work mentioned under the heading of "Work in Progress," will take in hand the survey of Heru-a-tureia Crown lands block of 3,990 acres. Mr. John Roddick, District Surveyor, will continue with several Native Land Court surveys in Waipiro, Mata, and Tokomaru Survey Districts. Mr. H. E. Walshe, Assistant Surveyor, has the survey of the Waipaoa Block in hand, as already mentioned. This will take up his full time well on to the end of the year, his only other work at present being the survey of a drain reserve at Argyll Settlement. Mr. Cagney, Assistant Surveyor, will carry out the survey of his portion of the Wharekahika Native Block. Mr. Gray, Assistant Surveyor, will continue the survey of the national-endowment block, after which he will survey a police reserve in the Taramarama district. Mr. Atkinson, temporary Assistant Surveyor, will take the revisional survey of the Manawaangiangi subdivisions, and simultaneously with this will carry on the subdivisional survey of the Mangamaire Block of 8,994 acres. He has several minor surveys on hand which he will complete at an early date. Mr. Primrose, temporary Assistant Surveyor, will continue the survey of the Wharekahika Block in conjunction with Mr. Cagney. This will occupy the full time of these surveyors until the end of the year. Mr. W. S. Thompson, temporary Assistant Surveyor, will continue the survey of the Waipaoa Block in conjunction with Mr. Walshe, and will be fully occupied with this work until well on to the end of the year. Mr. A. Hodgkinson, District Surveyor, who is to be transferred in April of the coming year to this district from Marlborough, will be given the following surveys : Road from Glenross to Omahaki Block; Timahanga Block, 17,600 acres; Omahaki Block, 15,710 acres, to be subdivided into small grazing-runs. Private surveyors will carry on the subdivision of 49,246 acres requisitioned for by the Native Land Court. It was found necessary to further increase the staff owing to the increasing work in the subdivision of Crown lands, land for settlements, and Native work carried out by staff surveyors.

Plans under check : There are 25 Crown plans, consisting of 106 allotments containing 48,811 acres and 24 perches, and 68 Native plans, consisting of 327 allotments and containing 39,200 acres 1 rood 8 perches, also 2 plans of revisional standard work of Napier and 1 plan of minor triangulation either under or awaiting examination. Fees collected for sale of lithographs, protractor sheets, tabulation forms, &c, amounted to £84 3s. Bd. Tracings for litho. purposes : 27 tracings were made for sale posters, &o. Miscellaneous tracings for field data, gazetting, Valuer-General, and various other purposes : 1,002 were prepared. Lithographs coloured : 111. District lithographs : Owing to the pressure of other work very little progress has been made in this section. One map, Tautane district, is very nearly complete. The county maps are being revised to fill the gap in the meantime. Other work : This consists of miscellaneous departmental duties; inspection of field-work of staff and private surveyors ; reports on roads to be opened and closed, &c. ; reinstatements of trigs, and standard pipes in the Towns of Gisborne, Wairoa, and Napier; engineering survey of drainage and roading at workers' dwellings, Hastings, &c. ; exchanges in connection with blocks purchased by the Crown; valuations by staff surveyors on areas proposed to be acquired by the Crown, etc., and a large amount of work done for other Departments; also the examination of survevors' unlicensed assistants. Transfers. —Mr. R. T. Sadd. my predecessor, was promoted to the charge of the Otago District at the end of March, being succeeded by myself, transferred from the Marlborough District. Mr. Hodjjkinson, District Surveyor, was transferred here to assist in coping with the increasing work in the field. General. —The work in this district is still increasing, and with the proposed acquisition of Native lands, both along the proposed Napier-Gisborne Railway and in other parts of the districts, and probablv the acquisition of more fstntos, the survey-work and land-settlement will be very considerable. The staff, both office and field, have done excellent work during the past year, and I have to thank thorn for their hearty co-operation with me in pushing ahead the landsettlement. W. H. Skinner, Chief Survevor.

TARANAKI. Minor Triangulation. —No work of this nature has been done during the past year. Standard Surveys. —Nothing of this kind has been done in this district for many years, but a revision and extension of the standard surveys of Hawera and Stratford are badly needed. Something should also be done for Eltham and the main roads through the valuable dairying country round Mount Egmont. Topographical Survey for Selection. —Under this heading an area of 25,220 acres, costing 4'34d. per acre, was got ready and offered for sale, and an area of 13,900 acres is now in hand. Mura1. —48,535 acres were completed, costing 2'965. per acre, most of which is situated in very rough forest country where the rainfall is heavy and continuous and location of roads difficult. An additional area of 34,000 acres has been completed in the field, and plans plotted sufficiently to allow sale plans to be prepared. Village and Suburban. —194'63 acres, in 18 lots, were surveyed at a cost of 12'485. per acre in wet bush country, the travelling-expenses being heavy. Town S'ection Survey. —An area of 4'28 acres, comprising 13 lots for workers' homes, was surveyed in the Town of Stratford at a cost of 31" 13s. per allotment. Native Land Court Surveys. —The total area surveyed was 47,241 acres, into 128 subdivisions, at a total cost of £2,832 13s. 5d., or 14'40d. per acre, the whole of the work being completed by private surveyors. During the year 73 plans were received for examination by Chief Computer, and 72 plans have been approved. Of these, 26 were received and duly approved for authorities issued prior to April, 1913, and 48 for authorities issued during the year. Twentyeight requisitions for surveys under the Native Land Act, 1909, covering 83 subdivisions of a total area of 44,880 acres, were received and authorities issued, the estimated total cost of survey being £2,648. Sixty-five subdivisions of a total area of 16,483 acres, representing 24 authorities issued during the year, have been completed and 48 plans of same received. Ten authorities issued prior to the Ist April, 1913, covering 36 subdivisions of a total area of 17,188 acres, have been completed, 26 plans received and approved. An area of 57,538 acres, representing 46 subdivisions covered by 11 authorities, are now under survey, and will be completed during the coming year. , Maori Land Board Surveys. —The total area surveyed amounted to 8,726 acres, comprising the Mohakatino-Parininihi lc West Block of 6,310 acres, for which authority was issued prior to the Ist April, 1913, for leasing purposes, at a cost of £331 15s. 7d., or 12'62d. per acre; and a block of 2,416 acres authorized, and completed by compilation at a cost of £15 15s. Roads. —ln this class 11"29 miles were completed by the staff and one contract surveyor at a cost of £246 ss. Bd., or £21"81 per mile. Inspections.- —Only 4 inspections were made during the year, 2 by Mr. District Surveyor Kensington of Native Land Court contract surveys, in both of which cases the boundaries were found to be very incorrect; and 2 by the Office Surveyor, Mr. Sole, both being inspections of Land Transfer surveys, where the question of occupation and search for old marks was considered unsatisfactory. More inspections would have been made had the Land Transfer Draughtsman and Office Surveyor not been laid aside by sickness. Other Work. —The expenditure under this heading amounts to £426 75., and includes inspections of surveys, inspections of survey contracts for payment, repairs and revision of old triangulation, also many miscellaneous isolated surveys of small area where travelling-expenses were proportionately heavy. Ghainage Closures. —The mean of all closures by the staff, mostly in rough bush country, gave an average of 0'94 links per mile. Office-work. —The total number of plans checked under all heads in the ordinary Survey Branch was 172, with 473 traverse sheets. These cover 420 sections, of a total area of 132,458 acres, and 31 miles of roads and railways taken and closed. Of these, settlement surveys of Crown lands were represented by 35 plans containing 170 sections of a total area of 55,205 acres; 34 plans defining 31 miles of roads and railways taken and closed; 76 Native Land Court and Maori Land Board plans of 59,690 acres in 126 sections; 18 miscellaneous plans of 22 subdivisions containing 3,707 acres; 6 office compilations of 8,759 acres in 5 sections; 2 township plans of 76 acres in 81 sections; and one provisional settlement survey of 5,020 acres containing 16 sections. Only one candidate sat for examination as authorized assistant and passed. Land Transfer. —In this branch 112 plans, with 163 traverse sheets, were checked and approved, covering 289 sections and subdivisions of a total area of 11,670 acres. Plans of the Mokau Block of 56,000 acres of private settlement lands, and a Maori Land Board block of 6,316 acres containing many miles of intricate roading, were also handed to this branch for examination. Practically for six months we were without the services of our Land Transfer Draughtsman, and had to utilize the services of the office surveyor for this work. Land Transfer record maps are badly needed, but owing to sickness and retirements, &c, the men left have had to strain every nerve to keep pace with the current work, and all record maps and compilations for publishing survey district and county maps, &c, have been hung up in consequence. Titles. —The plans placed on instruments of title of all kinds were 1,864, and 586 copies of leases and licenses were prepared, all by the office staff, and not, as for the past ten years, by contract. Compilations. —For photo-lithography 24 large drawings and tracings were prepared, and the work on the new survey district maps of Mapara, Tangitu, Rangi, and Piopiotea West was continued whenever opportunity occurred. These maps and county maps of Waitomo, Ohura, and Whangamomona are urgently required by the public and other Departments, and I trust an extra officer will soon be sent here to complete them and others of like nature,

C—lα

Miscellaneous. —The usual demands made on the office staff were attended to, comprising the supplying of information to the general public, tracings for Rangers and selectors, and diagrams and tracings to illustrate letters to Head Office for proclamation purposes. Fifty-nine complete sets of field data were supplied to staff and contract surveyors, and all necessary data for ElthamOpunake—Moturoa Railway route were supplied to the Public Works Department; while 153 special tracings from Land Transfer records were made for the Public Trust Office for revaluation of West Coast settlement leases. For the Valuer-General 152 tracings were made, while the total of tracings for selectors, Rangers, and illustrating tracings for Chief Surveyor, Head Office, and proclamation, &c, numbered 220. All recording on existing block sheets, Crown grant, 40-chain record maps,- reserves, index, and laud-tenure and wall maps was kept up to date, but there was no one available to prepare many new maps that are urgently needed, and I should be glad to see the draughting and computing staff strengthened by two more draughtsmen and a cadet. Native. Land Court. —The sum of £2,816 16s. has been received from owners and lessees of Native lands in payment of survey charges, &c, where costs were previously advanced by the Crown. Two hundred and fifteen plans (made by the staff, and not, as in previous years, by contract) have been endorsed and forwarded, covering an area of 77,097 acres, and 141 Native Land Court plans have been forwarded to the Registrars of Native Land Courts during the year for Native Land Court use or Judge's approval thereto. The outward correspondence under this head necessitated some 620 letters being drafted. Vouchers for payment to surveyors for survej's completed and approved have been prepared, and the usual detail work necessary has been attended to. The usual assistant to the Native Land Court Draughtsman was absent for four months on sick-leave. Proposed Operations for 191b—15• —A staff of four permanent surveyors, with two cadets and two temporal assistant surveyors, are at present engaged upon settlement surveys (including road access thereto through adjacent Native lands) along the eastern, north-eastern, and northwestern boundaries of this land district. The total area to be covered by these operations amounts to 78,000 acres, of which 34,000 acres is completed in the field, and litho tracings have been or will shortly be prepared for issue of sale maps, thus leaving 44,000 acres of new country on hand for the coining season 1914—15, situated in Mapara, Aria, Waro, Mimi, Pahi, Piopiotea West, Ohura, Waro, Pouatu, and Mahoe Survey Districts. Changes of Staff. —Owing to ill health Mr. F. J. Harrop was advised to try a change of climate from here to Auckland office, and Mr. Vaile, from Dunedin, took his place. Mr. Cadet Hancock joined the field staff under Mr. Wilson, and Mr. Hudson, of the clerical staff, became a draughting cadet. Mr. W. F. Gordon, after a long and faithful service of over forty years, obtained three months' leave from the Ist March preparatory to retiring on pension; while several other officers were absent on extended sick-leave ranging from one to four months, consequently the output of work has not been so great as I could have wished. The field staff had the disadvantage of experiencing very wet weather in the early part of the year, and this has retarded the output of work and made their duties more arduous. In the office, owing to sickness, the staff has been shorthanded at times, and extra assistance is needed, but the Chief Draughtsman, Mr. Lowe, has made it his business to meet the most urgent demands first, but such things as the preparation of new block sheets have had to stand aside. The staff as a whole has attended to duty in its usual efficient manner. G. H. BULLARD, Chief Surveyor.

WELLINGTON. Triangulation. —No work of this class has been undertaken during the past year, as the services of Mr. Girdlestone, who had been engaged for several seasons upon an extensive scheme of secondary triangulation, were urgently required in connection with ordinary settlement surveys. The pressing need for his attention in this direction is for the present over, and he has returned to the Head Office to resume his triangulation surveys. Standard Survey. —No work returnable under this heading was done during the year, Mr. Mountfort, District Surveyor, generally employed on it, having been occupied on similar work in another land district. However, there is nothing to be done requiring much urgency, and what there is can easily await the convenience of the Department. Topographical Survey. —The only work appearing under this head is a " paddock survey " of the Weraroa State Farm at Levin, but the field-work of 82,000 acres of Native land was completed by Mr. Blake, and will appear in next year's return. Rural. —An area of 26,163 acres is returned under this head, of which some 6,500 acres are now under occupation, with the probability of the remainder being offered for settlement within the next three or four months. At the present time three staff surveyors have on hand an area of 30,800 acres, which I expect will be completed and opened for selection before the close of 1914. (Note. —The Poroporo Settlement, of about 9,450 acres, was settled during the year, but is not included in the 26,163 acres returned by surveyor, because the plans are not finished.) Town Surveys. —There has been no work of this description extensive enough to warrant a particular reference, as any small sections have either been pegged off by the Inspecting Surveyor or by a staff surveyor, who includes such survey in his " other work " column. Native Land Court Survey. —The total area surveyed during the year under the authority of the Native Land Court was 65,785 acres, of which all but 1,328 acres was accounted for by

2—C. lα.

10

C—lα

private surveyors at schedule rates. An area of 100,683 acres is in hand Cor the coming year, authorities having already been issued to the various private surveyors. Roads. —Of the 20f miles returned only 6f (being portion of the Wanganui River-bank Eoad) are independent of settlement surveys. Other Work. —The main body of settlement survey is surrounded by a fringe of small surveys, reports, inspections, &c, undertaken usually in the winter recess, and which cannot be classified under the main headings. It includes, for instance, all the inspections which form the Inspecting Surveyor's principal occupation, also the cost of his duties as the principal office computer and examiner of plans. Proposed Survey Operation*. —One staff surveyor will complete the subdivision of the Waimarino A Block (Native) of about 14,850 acres, the work of which has hitherto been seriously complicated by the discord between a necessary scheme of loading and the suggested subdiyisional boundaries. Three staff surveyors will continue the present work in hand of the subdivision of about 30,800 acres of settlement land in the Whirinaki and Retaruke Survey Districts, and on its completion, three or four months hence, will proceed with the subdivision of scattered blocks aggregating 4,570 acres. Mr. Strachan on resuming his field-work will be similarly occupied. Apart from the 30,800 acres mentioned above, an area of 9,440 acres, representing the Poroporo Settlement, is completed, but owing to non-completion of plans has to be returned as "work in hand." Sufficient data, however, was obtained to allow sale posters to be published. Examination of /'Jans. — The number of plans approved during the year was 575, of which 255 were for the Land Transfer Department, 250 in the General Computing Branch, and 70 in the Statutory Plans Branch. The new plans in the General Branch covered 30,560 acres, comprising 108 sections, and in the Native Surveys 74,750 acres, comprising 601 subdivisions. Land Transfer. —In addition to the 255 plans approved, the branch also examined 67 applications, 1,496 transfers, 246 leases, 106 mortgages, 224 Native Land Court orders, 23 Orders in Council, 62 Proclamations, 390 balance certificates, 56 caveats, and 51 other dealings, besides placing 4,169 diagrams upon certificates of title. Native Land Court IFork. —A very considerable amount of work, passes under this heading. 130 requisitions for survey have been received from the Judges, and authorities issued for the survey of 83,448 acres at an approximate cost of £8,388. Liens have been collected amounting to £4,850 Bs., the repayment of which enabled 284 Court orders to be endorsed. Plans to the number of 172, showing 601 subdivisions and comprising 74,750 acres, were passed through. 516 charging-orders have been made, and 226 notices of release issued. A careful record of all outstanding liens has been compiled, and this very necessary information is now available in a concise form. General Draughting. —The ordinary work lias been somewhat hampered by changes and '"' strike matters," but good progress has been made with very necessary stock work, principally the preparation of district lithos, and during the season 16 plans have been drawn on 40-chains-to-the-inch and sent on for photo-litho. In addition to this 13 plans were prepared; 4 block sheets; 2 Crown-grant record maps; 2 trig, maps; 5 county maps renewed; 231 plans reduced and recorded; 73 tracings prepared for photo-litho; 1,335 tracings for general purposes; in addition to the large amount of work which it is impossible to schedule, but which accompanies nearly every case where titles and surveys are concerned. Changes of Staff. —The Chief Draughtsman, Mr. Maurice C. Smith, was promoted to be Chief Draughtsman in the Head Office, and Mr. Marsh, Chief Draughtsman, Dunedin, succeeded him here. Mr. Greville, Inspecting Surveyor and Chief Computer, was transferred to the Auckland District. In compliance with a medical recommendation Mr. Strachan, District Surveyor, was retired from the field to the office for twelve months. Messrs. Primrose and Seddon passed their surveyor's examinations, and were appointed as Assistant Surveyors in other districts, and Mr. Clements was transferred to this office from Hokitika. I understand that arrangements have been made to supply me with the services of several temporary draughtsmen and computers, with whose assistance I expect to be able to overtake some arrears which have accumulated in various branches. (Note. —At date of writing the temporary men are here.) General Remarks. —I have much pleasure in reporting that the surveyors in the field and the officers of the draughting staff have carried out their duties in a satisfactory and efficient manner. T. N. Beodriok, Chief Surveyor.

NELSON. Triangnlation. —The work under this heading completed during the year is 181,583 acres, chiefly in the Waitakere district, near Charleston, the average cost being l'4d. per acre. Standard. Survey. —The much-needed survey of the City of Nelson has now been accomplished by Mr. C. A. Mountfort, District Surveyor, acting under the control of the Head Office. Tα-pographical Survey for Selection. —An area of 26,000 acres has been completed at an average cost of 3d. per acre, the chief item being an area of 15,000 acres at the head of Lake Rotoiti. Sural. —Under this head the total area of 82,767 acres is returned, at an average cost of 2'l2s. per acre. Practically the whole of these areas were in heavy bush, great part on the West Coast, where rough country and a wet climate obtain. Thirteen staff surveyors with two assistants and four contract surveyors executed this work with commendable diligence. Town Selection Surveys. —Some 6 acres are returned under this head, the chief item being the Leaver Settlement for workers' homes in the Town of Westport.

11

C—lα.

Native Land Court Surveys. —There has been nothing done this year under this head. Itoad Surveys. —s6 miles were surveyed at an average cost of £23 per mile, which, considering the rough nature of the country and the difficulties of location, is very reasonable. The chief item was a roud, supplying a long-felt want, in the Totaranui district. Other Work. —By far the largest item, some £400, represents inspections both of staff and contract surveyors' work. With but few minor exceptions satisfactory reports were received, and the class of surveys shows a marked improvement on those examined last year. Proposed Operations for 19H-15. —Next year the staff will, it is expected, be engaged in extending settlement surveys, aggregating nearly 100,000 acres, including the following blocks : liotoroa, Matakitaki East, Glenroy, Maruia East, Mokihinui, Waitakere, Otumahana, Oparara, Waimea North, Rainy liiver, Orikaka, and Braeburn Extension. Office-work. —The staff throughout the year has remained at the minimum strength, and it has only been possible by strenuous exertions to cope with absolutely necessary work. Examination of Plans. —During the year 114 plans were examined and approved, in connection with which were 403 traverse sheets. Of these plans 68 were sectional surveys, 46 were road plans, and the remainder miscellaneous. Land Transfer Branch. —ln this branch 73 plans were approved, 149 applications and transfers were dealt with, and 178 certificates of title were made out in duplicate. Miscellaneous. —There was, of course, the usual voluminous mass of miscellaneous duties which cannot be tabulated, such as attendance on the public, correspondence, searches, &c. Changes of Staff. —During the year two excellent surveyors—Messrs. Stevenson and Nelson— attracted by private practice, retired from the service; Mr. Ingram, a, very promising young draughtsman, was transferred to Hokitika; whilst Mr. L. E. Ward, who had long ably filled the office of Land Salesman, was transferred to Napier, their places being capably filled by Messrs. Baigent and Galleu. In conclusion, 1 desire to thank both held and office staff for their active and intelligent co-operation in the work of settlement. F. A. Thompson, Chief Surveyor.

MARLBOROUGH. Triangulation. —A small amount of subsidiary triangulation was done in connection with the settlement surveys of the liillersden and Lynton Downs Estates. Rural. —Under this heading an area of 98,371 acres is returned at a cost of o'sBs. per acre. Included in this acreage is the land-for-settlements estates of Hillersden and Lnytori Downs, also a small block of bush country in the Sounds district. Topographical Survey for Selection. —An area of bush country containing 5,080 acres, situated in the Opouri Valley, Wakamarina Survey District, has been returned under this head. Town and Village Surveys. —Town comprises 22 sections with an area of 15 acres, and village 5 sections with an area of 88 acres. Roads and Railways. —With the exception of one plan all the work under this heading was done by private surveyors. Cold-mining Surveys. —Only 2 plans were received, with an area of 11 acres. Native Land Court Surveys. —An area of 1,005 acres with 11 subdivisions was surveyed during the year by private surveyors at schedule rates. Other Work. —The expenditure under this heading represents the cost of transferring surveyors from other districts. Field Inspections. —lnspecting Surveyor R. P. Greville made one inspection of a prviate surveyor's work during the year. A number of other inspections are required, and are awaiting the arrival of an Inspecting Surveyor. Traverse Closures. —Twenty-three circuits with a length of 78 miles returned by the staff show a mean closing-error of 1'42 links on the meridian and 0"87 link on the perpendicular. These surveys are all in rough hilly country. Proposed Operations for 191^—15. —The settlement-work for the coming year will be mainly in the Opouri and Wakamarina Valleys. This is all forest country over which the timber has been milled. In addition there is the completion on the true meridian of topographical settlement-work carried out last year in the Opouri Valley, also a number of spotting surveys in various parts of the district. Mr. Hunt has on hand 88,000 acres of topographical settlement-work (Hillersden leasehold) which will probably be completed in May. Mr. Hodgkinson has 4 miles of road through Native land which will be completed by the middle of April, and he is then under instructions to proceed to Hawke's Bay. Office-work: Examination, of Plans, &c. —The total number of plans received in the ordinary Survey Branch was 64 with 250 traverse sheets, comprising 38 departmental plans with an area of 102,900 acres in 104 sections; 4 Native Land Court plans; 20 plans of 37J miles of road and railway, and '1 compiled plans; 401 tracings were prepared, 4 tracings for photo-lithography, and 98 diagrams placed on Crown leases, &c. The draughting staff was also occupied in completing the surveyors' plans of Hillersden and Lynton Downs Estates. Land Transfer Branch. —In this branch 46 plans and 135 traverse sheets were received, covering an area of 72,511 acres; 437 diagrams were placed on certificates of title. The past year lias been one of greatly increased activity, notably in the land-for-settle-nients work, and I must thank the staff for the loyal way in which they have carried out their duties, and for their active assistance and co-operation during the year. H. G. Price, Chief Surveyor.

WESTLAND. Minor- Triangulations. —The year's return under this heading amounts to 10,000 acres, by Mr. A. N. Harrop, being the breaking-down of larger triangles in the Arnold and Waimea Survey Districts to control settlement surveys. Topographical Surveys amount to 18,100 acres, by Messrs. Morison and Harrop. These were made to cover a number of temporary leases which the Board wished to convert into more permanent titles. Rural Surveys comprise 20,385 acres in 120 sections. The mean cost of 2'Bs. per acre must, 1 think, be considered very reasonable considering the isolated nature of most of the work and the heavy bush cutting. Village and Suburban. —Mr. Cunningham returns 151'5 acres under this heading, being small sections in various parts of the district. Town Surveys. —The only item under this heading is a drill-hall site of 13 perches in the Town of Hokitika, surveyed by Mr. Wilson. Roads. —Only a few miles are returned under this heading, at a cost of £15'85 per mile. They were laid off to give access to isolated holdings. Other Work, of which full details appear in the schedule, amounted to £221 17s. 3d., and included inspections and reports on various matters, also cost of transfer of Mr. Morison and party to Marlboruogh and back, and six weeks' salary to Mr. W. Wilson on retirement. "Office-work. —The staff have had a busy year in keeping pace with current work. Owing to the amendment of the regulations for the holding of pastoral land in Westland, which came into force in March of last year, the Board has been able to convert a large number of temporary titles which had been granted on sketch-plans into the more permanent tenure. This has meant a lot of work in preparing data for the surveyors and in clearing up old discrepancies in the plans. The total number of plans received for examination was 88, with 198 traverse sheets, comprising 18 Land Transfer, 12 mining, IT statutory, and 41 relating to land-settlement. 739 diagrams were placed on deeds —namely, 551 on Crown leases and 186 on Land Transfer titles. In all 12 photo-lithogrnphic tracings were prepared, representing 20,000 acres of land, of which 15,500 acres were land for settlement. 487 tracings of all descriptions were made, including those for survey data, and 351 lithographs were coloured. Numerous lithographs were mounted and coloured for the use of the public, including one complete set of Westland. All the timber records and maps have been kept well up to date. Tracings and descriptions for Gazette notices have been prepared, while the usual routine work of recording, cross-indexing, mounting plans, &c, is well in hand; also the work of bringing into a proper state the recording and indexing of all the reserves in Westland. The block sheets. Land Transfer and Crown grant record plans still requite a considerable amount of work to bring them into a satisfactory condition, but it is hoped that some of these plans may be proceeded with during the ensuing year. Proposed Course of Operations for the Coming Year. —At present we have 25,630 acres awaiting survey, and these figures will be largely augmented by current applications during the year as°the sawmills advance with their cutting operations. Mr. Harrop is engaged on a block of 3,500 acres at Ruthergleu, for the purpose of converting temporary grazing leases into more permanent tenures, and Mr. Cunningham has in hand 2,700 acres of a similar class of work near Barrytown. Mr. Morison is engaged on spotting surveys. I propose to start with the survey near Bruce Bay as soon as the winter is over, and for this purpose it is essential that I should be provided with two more survey parties. Changes in Staff. —Mr. W. Wilson, Senior District Surveyor, resigned at the end of Novemb'er to enter into private business. He had been connected with the Department in this district for some twenty-eight years, and was-a most capable and energetic officer. I was exceedingly sorry to lose his services. Mr. D. M. Calder, Chief Draughtsman, left for Dunedin on promotion as from the 31st March. All the parties in the iield were visited by me at least once during the year, and in some cases two or three times. In conclusion, I desire to thank the staff for their active co-operation in carrying out the duties of the office. H. D. M. Haszabd, Chief Surveyor.

CANTERBURY. Triangulatiou. —No work of this nature has been done during the year. Topography. —Only 11,160 acres, near Ashwick, has been completed. Rural. —Under this heading 82,208 acres are returned, but most of the field-work of this was practically completed during the previous year. It comprises Ashwick, Mount Nessing, Lansdown, and Tara. Settlements, Crown lands at Oxford Bush, &c. Village and Suburban and I 1 own Section Surveys. —Very little has been done under this heading—47 acres and 16 acres respectively. Native Land Court Surveys. —There were only 9 subdivisions, comprising 63 acres. Gold-mining Surveys. —There were none. Roads. —The 20'55 miles returned included portion of Summit Road, access road to Oxford Bush, and also 11| miles of standard traverses near Rangiora, Fendalton, and Prebbleton. These traverses will prove very useful, as, owing to the increasing plantations and closer settlement on the Canterbury Plains, the ordinary system of triangulation can no longer be utilized in many localities.

Survey Inspections. —During the year 11 field inspections have been made, and the work has proved to be satisfactory. Other Work consists of inspections, reports, road-deviations, engineering, and other miscellaneous surveys. Proposed Operations for 19/.4.-15. —The work will comprise the subdivision of Runs 145 and 145a in conjunction with the adjoining freeholds when acquired; the standard survey of part of the Canterbury Plains; the survey of a new road over the extension of the Port Hills; the survey of any estates that may be acquired; and various small surveys in different parts of the district. Land Transfer. —During the year 388 plans have been examined and approved, embracing 120,794 acres; 2,748 transfers, leases, Proclamations, &c, have been dealt with; and diagrams (in duplicate) have been placed on 2,216 certificates of title, all the copies having been prepared in the office, as the contract for the supply of certain of these has been terminated; a set of 80-chain lithos has been mounted in 11 maps, showing all the counties and road districts, &c, in the land district. Many of the old deposit plans, having been in use for over forty years, are getting badly worn, and 10 of them have been replotted and 50 remounted. Office-work. —During the year 29 Public Works plans, 20 road plans, 32 land-for-settlements plans, and 28 miscellaneous plans were examined and approved. Tracings of two sheets of the Amuri County have been prepared for photo-lithography : these should be very useful. Changes in the Staff. —Mr. L. Hunt, surveyor, who was temporarily employed on settlement surveys here, returned to Marlboi'ough in April. Mr. Hathaway, unlicensed assistant, was transferred to Auckland, and Mr. T. A. Searell, cadet, to Wellington; Messrs. R. J. Cornwell and C. D. Gaudin, cadets, have recently joined the staff. In conclusion, I wish to record my appreciation of the hearty co-operation of the staff, both field and office. C. R. Pollen, Chief Surveyor.

OTAGO. Minor Triangulation. —No work under this heading has been done during the last year. Topographical. —Ranger Leonard accompanied Captain Head in the latter's expedition to the Upper Dart Valley and fixed the position of the Dart and other glaciers and the dividing range between the Dart and Arawaia Valleys. Rural and Suburban. —Our staff surveyor, Mr. S. T. Burton, has been engaged in this work, and as it was impossible for him to overtake it all it was found necessary to secure the services of two contract surveyors for the subdivision of Te Puke and Clareview Settlements, the former being carried out by Mr. M. Begg and the latter by Mr. J. B. Couston. The total area returned is 4,520 acres, made up as follows : 1,425 acres divided into 10 allotments in Te Puke and Clareview; 48 sections comprising 2,642 acres, consisting of small areas for settlement purposes, &c, scattered throughout Central Otago; and 453 acres carried out by private surveyors, the cost of the work being defrayed by the applicants. Standard Surveys. —Mr. W. T. Neill, Inspecting Surveyor, has made good progress with this work, but, as during the previous year, has been much hampered by unsettled weather. The work in the city, South Dunedin and Caversham, as provided for in the first agreement with the City Council, is now complete with the exception of the plans, which are in a forward state. In January work was commenced in the North-east Valley, and preliminary work has been extended along the Main North Road and over the townships to the south-east of this line. A 7 in. theodolite has been obtained for this work and improvements made in the measurement apparatus in order to secure the greatest possible degree of accuracy. Town Surveys. —The staff work under this head consisted of the subdivision of the unsurveyed portion of Dunkeld, consisting of about 30 acres divided into 89 sections, carried out by Mr. S. T. Burton, and the subdivision of the Dunedin Gaol-site into 3 sections by Mr. W. T. Neill, and the laying-off of a reserve in Koniako by Mr. Burton. Plans of 6 private townships were examined and approved under section 3 of the Land Laws Amendment Act, 1912. Mining Surveys. —The area surveyed for mining purposes was 445 acres, divided into 7 sections, the work being undertaken by private surveyors for the fees. Roads and Railways. —Twenty-one plans were examined and approved, all, with one exception, being the work of private surveyors. Land Transfer. —Ninety-one plans were examined and approved, comprising 8,690 acres. Proposed Operations for the Year. —The standard survey of the City of Dunedin will be continued under the direction of Mr. W. T. Neill, Inspecting Surveyor, during the year. Assistant Surveyor S. T. Burton has in hand 515 acres, 14 sections, spotting surveys, and 7,500 acres run surveys, and will be busily engaged during the year by keeping these spotting surveys up to date and assisting with the subdivision of the Omarama Runs—lß2,9oo acres —which are to bo subdivided into 7 holdings. For this work it is proposed to have the assistance of two additional surveyors from other land districts. Office-work. —During the year the following plans were examined and approved : 91 Land Transfer, 21 road and railway, 7 mining, 80 staff, making a total of 199. A new map on 40-chain scale of Leaning Rock district, for photography, was prepared, and 46 tracings for sale posters were made; 6 maps for the Land Office were drawn, and new record maps on the 20-chain scale of Tiger Hill and Benger districts were completed. A portion of the 4-mile map of Otago and Southland was redrawn and lithographed, and several sets of new townships and subdivisions

C—lα

14

also for addition to the Dunedin and suburbs map were lithographed here. In all some 720 tracings for various purposes were made and the usual diagrams put on Rangers' field-books. A number of working plans were drawn in the office, and the Valuation Department's maps are in course of revision. One draughtsman has been continuously engaged on the map of the Dunedin standard survey. Diagrams were placed on 71 leases in duplicate and 346 in triplicate, making a total of 1,180 copies. In the Laud Transfer Branch 985 deeds were examined and diagrams put in 940 certificates of title in duplicate, making a total of 940 copies. The Printer reports 1,282 lithos printed, 1,268 maps mounted, and 38 books bound. In conclusion, I beg to thank the staff for their co-operation and assistance in the work of the Department. Robt. T. Sadd, Chief Surveyor.

SOUTHLAND. Minor Triangulatio'n. —No work under this heading was done during the past year. Rural. —In this class a total area of 31,439 acres in 133 sections was completed; of this, 28,935 acres in 112 sections were executed by the staff at an average cost of l'sss. per acre, about 2,000 acres being bush country, hilly and flat, and the balance mostly undulating and hilly open country, including the subdivision of four estates acquired under the Land for Settlements Act, 1908—viz., Ardlussa, Fortification Hill, Knowsley Park, and Waiarikiki. Besides the foregoing, Mr. Falkiner has completed in the field a large amount of work in Waimumu Hundred, including the completion of the Landless Natives Block. These plans will be finished by the end of April. 1,850 acres were surveyed by contract surveyors at a cost of 2'235. per acre, consisting of prison farm at Invercargill, 650 acres, for Justice Department; 28 acres Riverton rifle range, in Jacob's River Hundred, for Defence Department; and 1,172 acres sawmill areas scattered throughout the land district, paid by deposits. The balance, 654'5 acres, consisted of 2 coal leases in Wairio Survey District, 1 subdivision of Crown lease under section 89 of the Land Act, 1908, in Lillburn Survey District, and several small miscellaneous surveys in different localities surveyed by licensed surveyors and paid for by applicants (direct costs not available). Village and Suburban. —An area of 162'3 acres in 30 sections appears undei this heading, the average cost of survey being 17'485. per acre. Twenty-seven sections were surveyed by Mr. N. L. Falkiner in Blocks IV and V, Campbelltown, and Block I, Invercargill Hundreds, and 3 sections in the Borough of Mataura by Mr. C. Otway. Town Section Surveys. —No surveys of this nature have been returned this year. Native Land Court Surveys. —One survey by Mr. H. R. Dundas is shown under this heading, containing 23 acres, and being Subdivisions A, B, and C of Section 66, Jacob's River Hundred (Aparima N.R.). Gold-mining Surveys. —Two special claims, one of 100 acres in Wakaia Survey District, Mr. P. B. Macdonald, surveyor, and one of 85'7 acres in Nokomai Survey District, surveyed by Mr. R. S. Allan, were returned during the year. Roads, Railways, and Water-races. —3 28 miles of roads were surveyed by staff surveyors at an average cost of £25'43 per mile, made up of short roads and deviations to give better access to Crown land sections, and 3'l miles of railway and private tramways through Crown land were surveyed by private surveyors and paid for by applicants direct. Other Work consists of various works which cannot well be shown under any of the other heads, and includes redefining of section-boundaries, inspection of surveys, exploration and roadgrading in connection with a block of Crown land in Longwood Survey District commenced by Mr. H. M. Thompson previously to his resignation, work in connection with East Taieri drainage scheme, several small survey reports, and miscellaneous duties. Inspections. —ln all 8 inspections were made during the year, 7 by Me. C. Otway, District Surveyor, and 1 by Mr. R. S. Galbraith, Chief Draughtsman, mostly of small Land Transfer surveys in various localities. These included work by all private surveyors usually practising in the district, and generally speaking the work was found to be satisfactory. Traverse Closures. —Thirty-six separate traverses returned by staff surveyors, totalling 151 miles, exhibit an average closing-error per mile of only 0'23 link on the meridian and 0"25 link on the perpendicular. Proposed Operations. —Mr. C. Otway is now engaged in redefining the boundaries of some Crown sections in Longwood Survey District and in the Town of Lumsden, which work he expects will be completed about the end of May; he will then undertake the subdivision of some 4,000 acres of Crown land in Lillburn Survey District and any further area that may be found suitable for settlement in that locality. Mr. D. Macpherson lias at present in hand the subdivision of about 5,100 acres bush land in Aparima and Jacob's River Hundred, which it is expected will occupy him until about December. His next work will be some 2,700 acres in Jacob's River Hundred. Mr. N. L. Falkiner has just commenced redefining boundaries of Crown sections in Waikawa and Mokoreta Survey Districts; afterwards lie has some 6 miles of road through Crown lands in Mokoreta Survey District to traverse. When these surveys are completed lie will be available either for the completion of the block in Longwood Survey District commenced by Mr. H. M. Thompson before his resignation, or for any other work which may arise in the meantime. General. —Besides the works enumerated I consider that it would be very desirable to have the standard survey of Invercargill City extended whenever practicable so as to include, at all events, the whole of the borough. There is also a very large area in the National Park which has

15

C—lα

never been explored or triangulated, and this work is worthy of consideration with a view to having it put in hand in the near future. Office-work. —During the year 15 new Land Transfer record maps have been prepared, comprising the Towns of Riverton, Mataura, Mataura Bridge, and Otautau, and the Winton, Oteramika, Mabel, Lothian, and Mataura Hundreds, and several old maps revised and brought up to date. A new Crown-grant record map of Manapouri Township was made, and several of the older working plans which were becoming illegible were redrawn. Two new lithographic maps were completed, containing a number of the interior survey districts, and 3 old ones revised, and I am pleased to say that these district maps now cover practically all the important parts of the land district. Four new application maps and 1 new index map have been finished, and 4 more of the former and 2 of the latter are in hand, but on account of the tax of ordinary routine work on the draughtsmen's time progress with these very necessary maps is unavoidably slow. Sixty ordinary survey plans, representing an area of 51,543 acres; 56 statutory plans, mostly of roads to be taken and closed; and 7 plans of new towns for Governor's approval were examined and approved. 1,078 diagrams were endorsed on Crown grants and other instruments of title; 89 lithographic tracings for sale plans, 493 miscellaneous tracings, and 314 working tracings were prepared; 148 Land Transfer and Deeds plans were traced, and maps of ridings prepared and revised for Valuation Department; 387 maps of various kinds were mounted, and 20 local bodies' schedules of " thirds,'' &c, prepared. A large map showing new ridings was made for the Wallace County Council, maps prepared in connection with three Supreme Court cases for Justice Department, and 3 maps of Waimatuku River District for rating purposes. Towards the end of January Mr. Deverell commenced the preparation of a map of the greater part of Otago Land District, on a scale of 2 miles to an inch, for lithographic purposes, and has since been continuously engaged on this work. The map is on the same lines as the one he drew of Southland, Wallace, part of Lake counties for this land district, and which has proved so useful here since its publication. Land Transfer Work. —l27 plans, comprising an area of 60,011 acres, were checked and approved, 1,539 diagrams placed on certificates of title (including 48 Proclamations, &c, coloured off on titles), and 581 deeds and other instruments of title examined and passed. The Land Transfer Draughtsman has the assistance of one draughtsman when required for endorsing of diagrams, &c. Changes of Staff. —The following changes in the staff occurred during the year : Mr. H. M. Thompson, Assistant Surveyor, resigned as from the end of May last; Mr. K. C. Mack was appointed to this office as draughting cadet; arid Mr. T. G. Phillips, draughting cadet, was transferred here from Auckland. In conclusion, I wish to thank the officers of the staff, both field and office, for their willing and efficient assistance in the work of the Department during the past year. G. H. M. McClurb, Chief Survevor.

APPENDIX 11.

The Chief Draughtsman, Mr. M. C. Smith, reports as follows : — Mr. H. T. McCardell, Chief Draughtsman, retired on superannuation after forty years" service on the 31st December, 1913, and Mr. H. Farquhar became Acting Chief Draughtsman until the end of January, when the duties were taken up by me. Among the new maps completed for publication during the year the more important are those of the Boroughs of Wanganui, New Plymouth, and Otahuhu, sheet 5 of the Auckland Land District, sheet 3, Grey County, and a number of survey districts brought up to date, together with a map of the Island of Rarotonga. A large map of Greater Wellington is also nearing completion, and will be published during the coming year, as also will a new map of New Zealand, the first issue of which will be on the international scale of one-millionth, although in some other respects it will not conform exactly to the International Map Committee's rules, having been laid down before their adoption. This map will also give some of the early French explorers' names upon the coast-line. Eleven schedules for the Local Bills Committee were examined and certified to; several county maps were renewed; some thirty loan-block maps, with an index map to the whole of those in the Dominion; twenty-one registration district maps, Forestry Commission maps, and a number of miscellaneous drawings for photo-lithography, including specimens for an investigation into possible extensions of that process for departmental work, were made. Work in connection with the examinations for licensed surveyors and Mines Department examinations was also performed. Thirteen surveyors' bands were tested and certified to, some 103 technical descriptions of districts made, and various computations. Departmental transactions in land and new surveys were also recorded upon the general maps to date; large numbers of lithographs were sold; 646 maps were mounted; sixty-four odd plans and 216 town plans were traced. Two hundred and forty-three plans of new " towns " under the Land Act were received and examined prior to submission for the Governor's approval. Alterations in the rooms occupied by the draughting staff were ordered by the Accommodation Board, and have been practically completed, but entailed considerable temporary inconvenience and difficulty during their progress, much of which is still imposed by the non-comple-tion of necessary fittings for displaced records. During the short time I have been in charge of this branch I have had much reason to thank the officers for the assistance readily given by all. The retirement of my predecessor, Mr. McCardell, lost to the Department one of its bestknown officers and finest draughtsmen, who had been identified with this branch since 1879, when he was transferred from, the Christchurch office to the Head Office staff. In his long period of service he was under all the departmental heads since the provincial offices were brought under central control under the late Mr. J. T. Thomson, Surveyor-General; lie was contemporary and collaborator with men who were, from their positions, known in district offices from end to end of New Zealand, and it will be long before his name will be forgotten.

APPENDIX lII.—TRIANGULATION. [By C. E. Adams, M.Sc., P.R.A.S., Chief Computer.] The office-work on the triangulation has comprised the usual routine of calculations, such as checking abstracts of horizontal angles and calculating spherical excess in preparation for noncircuit adjustments; preparing and draughting diagrams; adjusting polygons and triangles to consistent geometrical figures by least squares; calculations of latitudes, longitudes, and azimuths from co-ordinates; calculations of tables of PB 2 E tan <j> and of cot ft + 3tan ft „* to facilitate 6 <f>" these calculations; checking table of natural tangents to nine figures tor use in geodetical calculations. Mr. E. J. Williams has carried out these calculations in a satisfactory manner. Electric Measurement of Temperature of Steel and Invar Measuring-bands. —Further work has been completed at this research, and I have to acknowledge the valuable assistance of Mr. W. Stuart, M.Sc, and Mr. G. B. Dall, who have made extensive series of observations, and have now sufficient information to show that a simple practical and convenient outfit can be made for easy use in the field. Kaingaroa Base.—Length., 91198-830 links = IT4 miles; probable error, ± -0147 or 1 in 6,217,000; date measured, January, 1912, February, March, and April, 1913; total number of days, 43 = 3'B days per mile. Auxiliary base: Length, 12149-035 links =15 miles; probable error ± '0032, or 1 in 3,785,000; date measured, March, 1913; total number of days, 6 = 4-0 days per mile.

APPENDIX IV.— TIDAL SURVEY. [By C. E. Adams, M.Sc, Jb\.R.A.S., Government Astronomer of New Zealand.] Haemonic Analysis. The harmonic tidal constants for Dunedin have been obtained from an harmonic analysis of the hourly ordinates of the automatic tide-gauge records at Dunedin. Darwin's tidal abacus was used, and the whole of the measurements and calculations have been carried out in duplicate and with independent checks where necessary. The constants have been checked by computing from them the heights of the tide on different days and comparing the values with the gauge records. The results have shown that the constants have been determined correctly.

Tidal Prediction. From the harmonic tidal constants the tides for Wellington and Auckland have been predicted, using the method described in the Tidal Survey Reports for 1910—11 and 1911-12. The predictions give the times and heights of high and low water throughout the year. The time used is New Zealand civil mean time for the meridian, 11 h. 30m. east of Greenwich; and the heights are referred to the Admiralty datum of each port. The tidal predictions are supplied to the British Admiralty, and are published in the Admiralty Tide-tables; and to the Marine Department, and published in the New Zealand Nautical Almanac and Tide-tables. Checks of Prediction. —As in former years, checks are constantly applied to the predicted times and heights of high and low water by comparison with the latest available tide-gauge records, and in everj' case where such a test lias been applied the results have been most satisfactory and of a high order of accuracy. General. Further investigations into improved methods of harmonic analysis have been made from time to time, and it is expected that material economies in this highly complicated mathematical analysis will result. Much overtime has been taken up, in conjunction with Mr. W. S. La Trobe, M.A., Director of the Technical. College, Wellington, in designing a new tide-predicting machine. Until the invention is protected by patents it is not proposed to describe details here. The machine would appear to be a great improvement on all existing ones, and its employment would lead to highlj' increased economy. Messrs. T. G. Gillespie, J. J. Hay, and E. J. Williams have assisted in the calculations of the tidal survey in a satisfactory manner. Their work has been of an exacting and technical nature, involving great care to guard against errors, and has been carried out accurately.

APPENDIX V. THE MAGNETIC OBSERVATORY AND THE MAGNETIC SURVEY. Magnetic Observatory. During the year the regular observational work of the Observatory has been thoroughly carried out, and, in addition, with the aid of temporary assistants, a large amount of work has been done towards getting the great quantity of data accumulated by past observations into form for publication. For part of the year the Observatory had the able assistance of Mr. E. N. Webb, and for the last few months of the year the services of Mr. H. S. Richards were obtained. With the willing assistance of these gentlemen and of Mr. Maben the major portion of the magnetograms remaining unmeasured from past years has been measured, and the computation of hourly values from them has been well advanced. For the first time since the establishment of the Observatory it has been found possible to publish the vector diagrams for the immediately preceding year. The tables of hourly values of magnetic horizontal force and declination are also published herewith, and the approximate mean monthly curves for H and D are also given, and are very instructive. The Milne seismograph No. 16 has been kept in continuous operation, and data of 74 earthmovements recorded are given in tabular form. The Adie magnetographs have been kept in operation continuously, with the exception of the period 25th February to sth March, 1913, when the cellar was in use for pendulum-swinging. This explains the absence of data for these days in the published tables. The regular absolute observations were duly made to enable base-lines to be computed. The tabular data given in the tables are not affected with temperature variations, and are absolute values. Meteorological observations have been made twice daily throughout the j r ear, and three times on week-days. These have been published daily for public information. The mean annual values of magnetic elements for the year are as follows :— Declination E. .. .. .. .. .. .. 16° 42-01' Horizontal force. . .. .. .. .. .. 0-224485 c.g.s. unit. Inclination* . . . . . . .. .. .. 67° 58-2' Northerly component of force .. .. .. .. 0-215017 c.g.s. Easterly component .. .. . . .. . . 0-064508 c.g.s.

Magnetic Survey. The correction of the field observations obtained since 1899 to the same epoch has now been practically accomplished by me, the method used being, in the case of field-work since 1902, to compute the actual values at the Christchurch base at tbe time of the field observation, thus establishing the true station difference and enabling the values to be corrected by means of the known secular or annual change at Christchurch. In the case of older stations, made when the Observatory was not yet operating, a simple correction for annual change and mean diurnal change alone could be applied. The work of discussion of the results obtained is now being carried out with the collaboration of Professor Farr and Mr. D. B. Macleod, and we expect to obtain valuable results from the discussion of disturbance values. Diagrams. —There are published herewith twelve magnetograms exhibiting the most pronounced magnetic storms of the year. It has been found impossible to publish the vertical-force tables for the year, as my time has been more than fully occupied with survey data and in getting the H and D tables ready and in computing data for the vector diagrams, which work could not be undertaken until the latter tables, on which they are based, were finished. From tbe diagrams it is easy to see the times of maxima and minima of declination and horizontal force and of the northerly and easterly components. The hours on the curves are Greenwich civil time, Oh. corresponding to 11.30 a.m. here, local noon being at Oh. 30m. on the curves. From the declination diagrams it appears that there is an afternoon principal maximum occurring at about 2 p.m., New Zealand, and a principal minimum in the early morning at about 8 a.m. in summer, but not until 10 a.m. in winter. There is a secondary minimum shortly before midnight, about 11 p.m., which is most evident in winter-time. A secondary maximum occurs at 3 a.m. in equinoctial months, but becomes later in winter, being then at about 4.30 a.m. There is much more resemblance between the summer and equinox curves than between the winter curves and either. Winter variations are thus peculiar, probably owing to the great northerly zenith distance of the sun at midday. The student will find that the horizontal-force diagrams given exhibit similarly maxima and minima and amplitudes varying with the season of the year. The vector diagrams show very clearly the greater range of variation in summer and the smallness of changes during the nighthours. A complete theoretical discussion of these curves and of those of former years is contemplated. Had time permitted, range curves for the hours would have been made out, and would have proved instructive. I wish to return thanks to the donors of many and various scientific publications received, and I have also to acknowledge the willing assistance rendered me by Mr. Maben in the work of the year. Henby F. Skey, Director.

APPENDIX VI. Mr. J. Langmuib, Inspector of Surveys,- reports as follows on the measurement of the Kaingaroa Plains base, Auckland District: — This base was measured with all the care and same apparatus as used at previous basemeasurements. (See reports of the survey operations, Department of Lands, for the years 1909 to 1912.) Geographical Position of Base. —The northern terminal, or Trig. Station 38, now XLVII, Secondary Triangulation notation, is about south latitude 38° 25' 05" and east longitude 17fT° 35' 03". The southern end, or Trig. Station 34, now XLVI, is about 38° 32' 51" south latitude and 176° 27' 12" east longitude. Selection of Base. —The position of this base was chosen as the best obtainable in a central situation to control the triangulation of about 15,000 square miles of country, extending to the north-east as far as the East Cape, and including the meridional circuits of Poverty Bay, Hawke's Bay, Tuhirangi, and parts of Mount Eden South and Bay of Plenty circuits. Character of Country. —The character of the country over which the base runs is variable. About seven miles of the central portion is fair to good chaining country, being in great part nearly level, but both ends of the line are exceptionally rough for base-line work, as will be recognized by a glance at the longitudinal section and a reference to the " Remarks " column of Table No. 1. A marked difficulty, and source of considerable expense and delay, was the great scarcity of permanent water, the whole supply for the camp, including horses, having to be carted about four miles. Standard of Length. —The standard of length for the measurement of this base was the Imperial Standard steel tape No. 5, deposited with its balance No. 5 in the District Survey Office, Napier. On the 18th June, 1903, this tape was certified to by the Standards Branch of the Board of Trade, London, as being ()'OO6 in., or 0'000758 link, long at 62° F., or it is nominally standard length at 60 - 788° F., it being still desirable to have this value again verified with the British standard. Comparison with previous Triangulation Values. — Present determination ... ... ... ... ... 91198-8298 Value by the original triangulation derived from the Maketu base measured in 1868 ... ... ... ... ... 91202-2 Difference ... ... ... ... ~. 3-3702 It has been found, however, that the old Auckland standard was 0'026 link per chain longer than the new Imperial standard, therefore to bring the old work into terms of the Imperial standard 0'026 link x 912 = 23'7117 links to be added to the present triangulation value of the line, viz. :— 91202-2 + 23-7117 ... ... ... ... = 91225-9117 New chainage value ... ... ... ... = 91198 - 8298 Difference ... ... ... ... = 27'0819 The Maketu base was only 17809'7 links in length, and the systems of triangles through which the value 91202'2 was obtained are far from satisfactory. If the terminals of. the old Maketu base had not suffered damage it would have been interesting to have again measured it, but it is not at all necessary, as the line between the new secondary stations, Te Pare and Otawa, will control and check in a very satisfactory manner the immediate values in the old Maketu base net. An auxiliary base-line, 12149-0347 links in length, was measured as an' additional check on the measurements of Sections 8 and 9, but any values determined from it should not in any way enter into the final value of the main base-line, the results of the direct measurements being much more reliable. Results of the Measurements. —The least probable error in any section is in Section 7, where it amounts to + or - 0-00205 in 10924-6861, or 1 in 5,329,115. 'The greatest probable error is in Section 8, where it is +or - 0-00971 in 7966'9420, or 1 in 820,488. (See note to Table No. 1.) The probable error of the whole line is +or - 0-01467 in 91198-8298, or 1 in 6,216,689. Mr. Willis was the rear-end observer for Sections 3 and 4, and Mr. Goulding for the remainder of the base. The following tables and illustrations are appended : — Table No. 1. —Results of measurements (four sheets). Table No. 2. —Results of measurements of auxiliary base (one sheet).
