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.
