1 From Forest Tables — Lodgepole Pine. Circular 126, U. S. Forest Service, 1907, pp. 23-24. 
Lodgepole pine often occurs in dense pure stands in the 
Sierras. At high elevations it is frequently associated with 
Douglas fir, alpine fir (Abies lasiocarpa) and other firs. 
Lodgepole in pure stands ranges between 4000 and 30,000 
board feet per acre, the average over large areas being about 
8000 feet. 
The cut in 1919 was 16,281,000 board feet. 
Western Spruce. — The spruces of importance in the western 
part of the United States are the Engelmann spruce (Picea
