184 THE WOODSMAN’S HANDBOOK, 
Volumes for small trees may be increased considerably by closer 
utilization in the top, since in some localities 6-inch logs are now 
taken. . 
The Montana data were tabulated first separately, which showed 
no consistent variation from the California trees of the same diame- | 
ter and height. The Montana measurements were made in a mixed 
forest with western larch and Douglas fir. Some Montana yellow 
pine stands will probably require the use of the Arizona or Black 
Hills volume tables.
