 slender, cord-like branch- 

 lets which sometimes 

 sweep the ground. Large- 

 ly cut for fuel. 



West slope of Sierras at 

 lower edge of yellow pine 

 belt. Of no commercial 

 use, but important as ef- 

 fective cover for rocky 

 slopes, as water runs off 

 barriers. 



Garry oak is the only tim- 

 ber oak of the northwest 

 coast country, and for this 

 reason it deserves the 

 forester's careful atten- 

 tion. 



Shrub under six feet in 

 height. Has value as a 

 slope cover. Mountain 

 slopes in dry, rockv, and 

 gravelly soil. Variable.

 close grained. Through-

 tain ridges, slopes and 

 canons.
