Section 8 in General Rules for the Localization and Demarcation of Enclosures in Reserved Forests
8. To secure business like and straight practicable lines, much care and thought is necessary. The line, in as long sections as possible, should run evenly along the limits, or in the direction of the main points aimed at, and taking no more turns than are necessary, the points or turns of a line should be chosen and described so that from one point the next may be readily seen with the naked eye (or will be so seen when the line is cleared) and all of them should be as conspicuous as possible, especially from the outside of the reserve. For this reason, points should, whenever possible, be chosen on high places and open spaces and they must be so selected as to allow of the lines between them running straight.
