Location. — This workiiiK circle, a subilivision of tlio riunias N'atiimal Forest, 

 is about 8 miles we.st of Quincy. the cuiinty seat of riuiiias C<iunty. Calif. 



Acreage. — An area of 37,995.10 atres is eiiihrared witliin the boundaries of 

 this workinj: circle. The (Jovernnicnt mntrols lis.S().">.2ri acres, and 9.1S!t.91

 ridges. This rise in elevation takes place in a horiznntal distance of less than 

 :i miles.

 tailed site classes of little use at the jircstMit time. Two site cbi'^^t's. conform- 

 ing to the standards for site Classes II and III, have accordingly been reecig- 

 iMzed. There is a narrow fring(> of true <'lass I around (be valley. This, 

 however, forms such a small percentagi- of the total ncrea^'e that for the pur-
