the true meridian from the fixed meridian, as previously determined by the last test of the instrument used; and such variation shall be distinctly written in figures between the fixed and magnetic meridian, as indicated by the instrument. (See specimen map.)

11. Lines of Construction.

The Map must show the work as executed in the field.

All measured lines and figures in red.
Calculated lines and figures in black.
All observed bearings and figures in blue.
Calculated bearings and figures in black.
All tie lines, observed or measured, to be dotted in their respective colours.
Boundary of claims to be shown by yellow marginal shading. Machine sites by pink. Mining Leases burnt sienna. Agricultural Leases or allotments by green.
Water races and permanent water to be shaded in blue, with the approximate discharge, in gallons, per second, written in blue—(ex 6½ G).
Approximate trend of reef or leaders within the boundary of the survey or adjoining claims to be shown on plan by red and yellow parallel lines (broken) not more than 1-100th of an inch apart, to be indicated by an arrow, pointing in the direction of the reef or leader, with the bearing written opposite the point (thus ➔ 20°), the underlay to be shown by a broad arrow with the angle given in degrees (thus 45°).
All roads or tracks passing through the claim, to be shown by dotted lines. Colour to be raw sienna. Surveyed roads by defined lines of raw sienna.
Area of Quartz Claims to be given in square feet, and the number of men holding the ground, to be written along with the title of the plan.
Alluvial claims to be same as above.
Mining Leases to have the area given in acres, roods, and perches.
Machine Sites—same—acres, roods, perches.
All topographical features to be shown on the plan by Indian ink or neutral tint, shaded of depth corresponding to the angle of inclination on the ground.

12. Title of Map.

The title of the Map must be as short as possible, and need not contain more than the name of the claim or lease, that of the district and block in which it is situate, date of the survey, and signature of the Surveyor in full.

13. Field Book.

The Map shall be accompanied with a list of the bearings and lengths of each measured line, which have been determined on the field, and must be furnished on form D; such form shall be duly dated and signed by the surveyor, but if from any apparent error being discovered in the Map, the Engineer-in-Chief should require the Surveyor to produce the original Field Book, the Surveyor must produce it accordingly, failing which, the Map will not be approved.

Surveyor must personally superintend the field work.

14. Every survey shall be made under the personal direction of the Surveyor signing the Map; and if any Surveyor shall attach his signature to the Map of any survey which he has not personally conducted in the field, he will be liable to have his appointment as a Gold Field Surveyor cancelled.

Notice to parties employing Surveyors.

15. Parties employing gold field Surveyors for the purpose of making surveys required under the Gold Fields Regulations, are informed that upon the completion of such surveys, the Maps have to be examined in the office of the Engineer-in-Chief, and if defective, such defects must be remedied before the Map can be approved.

Test of Accuracy of Surveys.

16. Beside any test of the accuracy of a Map, which the Engineer-in-Chief may consider necessary to make on the ground, an office test of the accuracy of the field work, plotting, and contents, will be applied through the medium of Latitudes and Departures, and by such other notices as may appear to be necessary.

Certificate of Completion of Map.

17. Upon the Map being approved by the Engineer-in-Chief, a certificate will be given to the Surveyor (if required), to the effect that the rules and regulations have been complied with (as far as practicable), and that the Map has been approved. (Form E.)

Defective Surveys.

18. Maps deposited in the Office of the Engineer-in-Chief, which are grossly at variance with the foregoing rules and regulations, or are defective or inaccurate, will at once be rejected, and a repetition of such defects will render the Surveyor liable to have his License suspended by the Chief Surveyor of Gold Fields, and his appointment cancelled at the pleasure of the Superintendent.

CHARLES O’NEILL,
Engineer-in-Chief and Chief Surveyor of Gold Fields.

8th March, 1869.

N.B.—The foregoing rules and regulations will apply, generally, to the surveys of water courses and roads, but as regards tramways and railways, special instructions suitable to each case, will be given to the Surveyor upon application to the Engineer-in-Chief.
