Memoranda to be kept of Dates of Tests of Chain, &c.

8. Every Surveyor shall keep memoranda of the dates upon which his chain was tested and corrected, and where such examination was made; and also of the dates upon which his Theodolite, or other similar instrument, was tested for variation of the needle, so that evidence of the same may be produced before any Court, whenever it may be required.

The dates of such tests shall be regularly communicated to the Engineer-in-Chief according to the form C.

Chains and Instruments to be open to Inspection.

4. All chains, Theodolites, and other instruments used on any survey within the limits of the Gold Fields, shall be open to the inspection of the Engineer-in-Chief, and subject to his approval.

Surveys to be connected with previous Surveys and Stations.

5. Every Survey must be connected, by direct measurement, with any other former survey, trigonometrical, or other stations, which may exist at the time of the survey when such comes within half a mile of any portion of the land to be surveyed. When the land lying between the old and new survey is free from dense bush, and where trigonometrical or other stations are visible, but beyond half a mile from any portion of the land to be surveyed, such stations shall be fixed in the following manner, where such is practicable:

A. If only one station is visible—Four very accurate bearings must be taken to the object from four separate and well-selected stations forming part of the survey.

B. If two stations are visible—Each of the stations must have very accurate bearings taken to them from four well-selected stations (adjoining each other) in the survey.

C. If three stations are visible—It will be sufficient to take very accurate bearings to each of the three stations and a bearing from either of the next adjoining stations of the survey, to any one of the trigonometrical or other stations; always selecting the best-conditioned triangle.

All the lines of bearings intersecting these trigonometrical or other stations must be laid down on the map by dotted blue lines, when there is sufficient room for the purpose; but where there is not sufficient room, then a portion of each line only may be laid down; and in all cases the bearings of these lines of intersection must be written in blue below the line, and (when their length is calculated) the distance must be written in black above the line.

When the extent of the survey is small, or the measured lines very short, fixing to trigonometrical or other stations by the method described under A and B is undesirable; the angles, in such cases, will not be well conditioned (except the stations are close to the survey) and the results will, in most cases, be unsatisfactory; it is therefore the duty of the surveyor to fix the relative position of the survey by connecting it with three outside stations after the method described under C, when such is practicable. In addition to the above-described connections, all surveys must have a bench mark or point given as a reference, such point to be marked on a rock or large tree with a broad arrow cut deeply into the wood, the kind of tree to be noted in the plan.

Streams and other features to be fixed and named.

6. All streams, or other features of the country lying adjacent to the survey or existing within the limits of the land under survey, must be properly fixed, and if possible, their names written on the map; and where the survey abuts upon land which has been previously surveyed, the lines and angle pegs of such former surveys which form a common boundary shall be accurately surveyed and have the lengths and bearings of the lines, and the position of the pegs, truly shown on map of new survey.

Boundary lines to be marked on the ground.

7. All corners of claims are to be distinctly marked on the ground, in accordance with the Gold Fields Regulations.

Size of Maps.

8. All Maps must be drawn on paper of good quality, and well seasoned. The size of the paper on which Maps are drawn must not be less than 17 x 15, in any case.

Scale of Maps.

9. The scales to be used are:

For town, village, or garden allotments, and for all miners’ claims, and other small areas—one chain to an inch.

For Mining Leases—Two chains to an inch.

For Agricultural Leases, Water-courses, and Roads—Four chains to an inch.

The Scale must be both drawn and written on the Map.

Meridian and Variation.

10. Each Map must have a meridian line drawn upon it, to represent the fixed meridian as laid down by the Engineer-in-Chief, and the variation from that meridian must be shown by another line, indicating.
