New Method of Making Conventional Signs on Original Topographical Maps
The use of characters, rather than colors, to represent on maps the different kinds of vegetation, soil, etc., has mainly been restricted to maps issued by the General Government. The principal reasons for this have doubtless been that the former, being hand work, was too expensive, and required too much time for general use; and, furthermore, draughtsmen skilled in this class of work are quite rare. No system of colors can give as satisfactory a representation of the surface features of the section mapped as can be obtained by a proper use of conventional characters. If it is desired to reproduce the originals by photo-lithography or analogous processes, the latter style is far more economical.
