NATIONAL FOREST RESOURCES 173 



of timber which can be cut from each National 

 Forest, according to sound forestry principles, is 

 authorized by the Secretary of Agriculture. This 

 cut is based upon the best available data as to the 

 amount of mature and over-mature timber need- 

 ing removal, and the amount of annual growth on 

 each Forest. At the present time only a small per- 

 centage of the authorized annual cut of the Forests 

 is taken. Most Forests cut a very small part of 

 their annual allotment, but a few Forests cut their 

 full annual yield, or nearly so. On some Forests, 

 the entire annual yield is used by local industries 

 and no timber can be sent to the general market; 

 on others a very small part of the annual yield is 

 used by local needs and most of the cut can be sent 

 to the general market. On the Cascade National 

 Forest, in Oregon, for instance, the annual produc- 

 tion is estimated at about 200,000,000 feet, while the 

 present local needs can be supplied by approx- 

 imately 1,000,000 feet. From such a Forest a 

 large annual cut can be made for the general mar- 

 ket. On the Deerlodge National Forest, in Mon- 

 tana, on the other hand, the annual yield is esti- 

 mated to be about 40,000,000 feet, all of which is 

 needed to supply the large copper mines near Butte.
