the survey, in the form or to the effect given in Regulation No. 111.

SURVEYS TO BE CERTIFIED UNDER THE PUBLIC WORKS ACTS.

46. The traverse should be connected at intervals not greater than two and a half miles to the trigonometrical stations of the district, as well as to the corners of the sections or properties through which it passes.

47. Where no triangulation exists the traverse should be chained and observed twice, and, if possible, connected at, say, three-mile intervals, to some permanent topographical feature outside the line of formation, at which place a peg should be placed and lockspitted.

48. The lengths of the sides of the area proposed to be taken for the work should be given to each property, as well as its true position in the property.

49. The distances on the meridian and perpendicular of each traverse peg must be tabulated. The surveyor, if he connect with a trigonometrical station, must use it as the initial point or zero of his traverse; failing a trigonometrical station, then a corner of a property should be used; and, failing a property-corner, some of the permanent topographical points hereinbefore referred to should be used as zero.

50. The error in closing on the triangulation should not exceed 8 links to the mile, and the total error in any traverse should not exceed 20 links, except in very rough ground.

51. The traverse should commence at the same end, and the pegs should be numbered in the same direction, as that of the original engineering traverse, if any, and each sheet should not contain more than one mile, and should be plotted upon half a sheet of antiquarian drawing-paper, to a scale of 8 chains to 1in.

52. The names of the present owners of properties, the number of sections or subdivisions, blocks, &c., should be written on each, wherever they can be ascertained; also the area of land taken for the work from each property or separate holding.

53. The ground-marking, pegging, &c., should be done generally as directed in a previous part of these instructions.

54. Maps should be drawn in the colours hereinbefore prescribed for working plans. Boundaries of road districts should be edged in light colour, and the name printed in same colour, every district having different shades or colours. Lands to be taken to be coloured in different shades or colours for each adjoining property; roads to be closed to be coloured green.

The plan is to be certified as correct by the surveyor who made the survey, and also by the Chief Surveyor holding a certificate under “The Public Works Act, 1882.”

55. An accurate schedule of the land proposed to be taken from each property must be furnished with the plan in the form given in Regulation No. 109, certified as in Regulation No. 54.

CONTRACT SURVEY.

56. No surveyor can be considered qualified to be a contractor unless he is an authorized surveyor, and has had five years’ experience in an approved system—that is, in any system whose field operations are subject to mathematical check.

AUTHORIZED PRIVATE SURVEYORS.

57. A surveyor in private practice, whose plans have to be approved by the department before obtaining a diploma, must apply to the Chief Surveyor of the district in which he proposes to practise, who will require exhibition of certificates. These must testify—
    (1.) To personal good character;
    (2.) To professional proficiency;
    (3.) To at least three years’ service in the field in a system of surveying similar to that of New Zealand, or to six months’ service with an authorized surveyor in New Zealand, in addition to foreign cadet service.

58. If certificates be satisfactory in regard to character and attainments, then surveying and mapping instruments complete will have to be shown. Candidates for authorization may also have to pass an examination in mathematics, including geometry, mensuration, trigonometry, and algebra; and in the use of surveying instruments.

59. The applicant must also produce plans of land actually surveyed in the district and drawn by himself completely and in a workmanlike manner, in accordance with these rules and regulations,—
    (1.) Of a base line at least one mile in length;
    (2.) Of at least three triangles as observed in minor triangulation, with topography, bearings, distances, summation, reductions on meridian and perpendicular &c.;
    (3.) Of a property of at least 100 acres, connected to a trigonometrical point, with bounding and intersecting roads traversed reduced on true meridian, drawn to proper scale, with tables, title, &c., in a form recordable in the office, as executed by the staff;

(4.) Of a city or town property of one or more acres, with existing buildings, &c., to represent a plan under the Land Transfer Act.

60. The Chief Surveyor will, upon compliance with these conditions to his satisfaction, sign and forward a diploma for the approval of the Surveyor-General, and if so approved the applicant will be placed on the list of authorized surveyors.

QUALIFICATIONS FOR ENTRY INTO AND PROMOTION IN THE SURVEY DEPARTMENT.

61. The candidate for apprenticeship must exhibit a satisfactory certificate from his schoolmaster, also a certificate of his having passed the junior examination under “The Civil Service Act, 1866.” He must be over sixteen and under twenty-five years of age.

62. Besides the above, a satisfactory departmental inquiry as to good eyesight for observing, a healthy constitution, a knowledge of geometry, trigonometry, and algebra, a legible hand, and taste for drawing, are necessary to qualify.

63. The Government will pay a salary of £50 for the first year, £60 the second, £70 the third, and £80 the fourth, together with an allowance at the rate of 2s. a day, or 14s. per week, while in tent.

64. The teaching surveyor will receive a sum of £50 when the apprentice passes his survey examination satisfactorily at the end of the three years.

65. No surveyor will be required or allowed to receive more than one apprentice.

66. Every facility shall be given to the cadet by the surveyor under whom he may be placed to enable him to acquire a thorough knowledge of the public survey system.

67. During apprenticeship (which extends over four years—one in office, and the remainder in the field) the senior examination of the Civil Service Regulations above quoted must be passed. If this be passed, it will also be necessary, previous to receiving a diploma or promotion, to undergo a departmental inquiry as to knowledge of practical geometry and the first six books of Euclid, plane trigonometry and algebra as far as quadratic equations, surveying and levelling, the use and adjustment of the theodolite, and map-drawing. A certificate of good conduct and competence from the teaching surveyor must also be shown. These requirements being complied with qualify for promotion into the grade of section or assistant surveyor. A knowledge of elementary geology, mineralogy, and botany will be considered of value in giving promotion to the grade of assistant surveyor.

68. In order to obtain employment in the geographical or standard branch, the candidate must have further a knowledge of spherical trigonometry; of the use and adjustment of sextant, alt-azimuth, and transit instruments; also of practical astronomy, particularly in reference to latitude, longitude, and true meridian.

OFFICE RECORD.

69. Field-books, working plans, record maps, and documents relating thereto and to titles, are to be kept in a fireproof safe.

70. Working plans, whether of meridional circuits, major triangulations, minor triangulations, or block surveys, should be drawn on antiquarian paper, cut to 30in. square. These are to be laid flat, in folios 33in. square, which again slide in to level shelves 34in. square, constructed in a closed press, set up in the fire-proof safes attached to the Survey Offices. Where there is not room for laying flat, folios may be placed upright. The working plans of isolated sections are also kept in folios 18in. by 16in. All these plans should remain unmounted, except under special circumstances. The compiled or index plans, however, being unavoidably of large size (56in. square), are mounted and kept in rolls; but these if destroyed are replaceable, containing as they do no original work. The tops and bottoms of these maps should have thin laths glued to them, and extra-fastened with copper tacks. This prevents the paper breaking and creasing.

71. The following are the scales to be used in surveys:—

Town sections, or sections under half an acre .. 2 chains or 1/40 mile to an inch.
