Fic. 4.—Method of tallying standard logs and diameters. 
Both diameters and heights are judged by the eye, but calipers 
may be carried, with which to check frequently the measurements. 
The accuracy of this method may be slightly increased by 
tallying, in a class by themselves, the dimensions of every one of 
the larger trees, instead of only 1 in 5. 
Ii 50 per cent of the area is covered, 10 per cent of the total 
stand is tallied, and the total estimate is found by computing 
the contents of the recorded trees and multiplying by 10. This 
result may be modified by a correction factor if it is evident that 
the timber not counted differs in stand per acre from that estimated.
