IDENTIFICATION OF THE PICTOGRAPHERS.
The first point in the examination of a pictograph is to determine by what body of people it was made. This is not only because the marks or devices made by the artists of one tribe, or perhaps of one linguistic stock if not disintegrated into separated divisions distant from each other, may have a different significance from figures virtually the same produced by another tribe or stock, but because the value of the record is greatly enhanced when the recorders are known. In arriving at the identification mentioned it is advisable to study: 1st. The general style or type. 2d. The presence of characteristic objects. 3d. The apparent subject-matter. 4th. The localities with reference to the known habitat of tribes.
