RULE VII.—SUBJECTS OF EXAMINATION (ORAL AND PRACTICAL).

The subjects of oral and practical examination shall be the following:—

No. 11. Field practice.—The practice of surveying with a knowledge of the Acts and regulations bearing on same. A practical field test may be required.

No. 12. Adjustment and use of instruments.—The principles of construction and practical tests in the adjustment and use of all instruments required in modern field practice and office work.

No. 13. Practical field astronomy.—Practical determination of time latitude and azimuth in the field.

No. 14. Practical levelling.

RULE VIII.—ORDER OF EXAMINATION.

(1) No candidate shall present himself for examination in subjects numbered 1 to 4 inclusive until he has completed to the satisfaction of the Board not less than two years of his term of articles, less any exemption to which he may be entitled under Rule IV hereof.

(2) No candidate shall present himself for examination in subjects numbered 5 to 10 inclusive until he has completed to the satisfaction of the Board the whole of his term of articles, less any reduction to which he may be entitled under Rule IV hereof.
