will probably average close to 6,000 feet an acre. Conservative 
estimates for the area would be 10,000,000 acres, and for the total 
stand, 50,000,000,000 feet. 
There is much wastage in butt logs, due to “ pitchiness ” resulting 
from fire scars and natural causes. Fires tend to make the stumps > 
more resinous and to increase the number of those sufficiently “ fat ” 
to serve for purposes of distillation. It has been the experience of — H 
an Idaho lumber company that some of these “ pitchy ” butts occur 
in all the western yellow-pine timber. They state that these pitchy 
butts are more prevalent in the northern section of Idaho, but that 
this territory and the Baker, Oregon (Blue Mountain), territory pro-

has come under their observation. . 
From this it would seem that the question of “ pitehy ” butts is 
important, and should not be ignored by those who attempt to de- 
termine the amount of resinous wood to be obtained from any lo- 
cality. Since 25 per cent of the butt logs from the Blue Mountain 
region bear more or less pitch, and a wastage in “ pitchy ” butts ~ 
trimmed off of from 4 to 5 cords a day is reported by one company, 
this constitutes a very important source of valuable wood for dis- 
tillation purposes. Samples sent to the University of Idaho com- 
pared favorably with the best stumpwood in yield of products. The
