Not illustrated. 1917 Excerpt: ...a discussion of the execution of the symbol on topographic maps. All symbols will be shown in black in the figures following. The conventional color to be used in topographical drawing in color will be given in connection with the illustrative figures. In the following pages, the abbreviated terms "six-inch map" and "one-inch map" will be used to refer respectively to maps of scale six inches to one mile (1:10,560) and one inch to one mile (1:63,360).

In all large scale maps, symbols are drawn to scale if the scale dimension calls for a size larger than the type conventional symbol. The conventional signs for one-inch maps have been re To illustrate, the symbol for rice hereafter shown was adopted to replace a former symbol much more difficult to execute. There were many square miles of rice land in the area to be surveyed in the Philippine Islands, and it was estimated that a saving of $600 could be made in the draughting cost of the work in contemplation by the adoption of a simpler symbol for the representation of this class of vegetation. The simpler symbol was accordingly adopted. duced to the minimum for easy legibility. For smaller scale maps the same dimensions of symbols are retained, and if the conventional symbol is inapplicable in the map area available, the information must be omitted.
