23. The paper on which the drawing is made is to be perfectly white and smooth, free from dirt, creases, or wrinkles, and of such quality as will admit of a second or third drawing surface if necessary after erasures have been made. Tracing-cloth may be used, but tracing-paper, unless perfectly white and the drawing carefully done, is inadmissible.

24. The drawing is to be executed with good Indian ink, freshly rubbed down, quite black, and free from grit or glaze, a little indigo blue mixed with the ink will improve it.

25. The lines are to be firm and clean, not too fine or too close together. They must all be perfectly black, and pale ink must on no account be used. Thick lines in the printing and borders should be well filled in. Washes of any colour are inadmissible.

26. If cross-hatching or shading is required, the lines composing it must be kept as open and distinct as possible, and they should not be too fine, but firm enough to reproduce well. Generally it is better to have fine hatching done by transfer from plate, and in such case the drawing should give only the outline. Intensity of shade should be shown by an increase in the thickness of the lines rather than by their being placed close together, as it must be borne in mind that throughout the process there is a tendency for the lines to thicken, so that if they are too close they are liable to block up in the printing, and the work will appear heavy and unsightly. This rule also applies to hill-shading, the darker portions of which should be drawn in thick distinct lines, but not crossed and recrossed with fine lines.

27. As the process produces a perfect fac-simile of the original, it is essential that the latter must be complete in every respect, and the drawing, printing, and writing should all be done in as neat a style as possible, so that the result may be fit for immediate publication, and not require to be altered or touched up after transfer to stone, by which the work is always damaged more or less. The hair strokes of the printing must not be too fine. Border lines, which could not be conveniently shown on a large scale plan, can be drawn on the stone.

28. When plans are intended for reduction, the lines should be of the proper thickness relatively to the scale of reduction. The printing and detail must also be relatively large in proportion. This rule is often neglected, and the result is the loss of all the finer lines, words, and figures. When drawing for reduction, care must be taken to leave sufficient space between the lines of the hill-shading, water-lines, or cross-hatching, so that they may be well separated when reduced, and may not block up in the printing.

29. When possible, it will be better to draw the original on a larger scale than is required for the copy, as a photographic reduction is always much sharper and much clearer than a reproduction.

30. In all cases a scale is to be drawn on the plan, and not stated as a scale of so many chains, feet, or miles, &c., to an inch.

31. In preparing maps and plans (other than for the Defence Department) no reference whatever is to be made therein to forts, works of defence, submarine mining, torpedo establishments, electric-light emplacements, &c.; and no public plan should show these works.

32. The preparation of plans and certificates by officers for private persons is strictly forbidden; and no officer is allowed to undertake private work.

DEPOSITS.

33. Deposits made for surveys to be executed by or under the authority of the Lands and Survey Department are in the first instance to be paid to the Receiver of Land Revenue or of Gold Revenue, as the case may be, and shall be by him placed in a deposit account.

34. When the plans are received and have been approved, the Chief Surveyor shall—in cases where the survey has been made by an officer of the staff—forward to the Receiver an abstract or voucher, duly certified, in favour of the “Public Account, Lands and Survey Vote.” When the survey has been made by an authorised private surveyor, an abstract or voucher for the sum or sums due, in favour of the person employed, shall be sent in like manner.

35. The Receiver of Land or of Gold Revenue may, after approval of a voucher by the Chief Surveyor, pay to the person entitled any sum up to 50 per cent. of amount of deposit, and on
