FOREST RESOURCES 15 



Incense cedar is not cut into lumber to any extent, because 

 of the excessive taper of the bole, and also because a large per- 

 centage of the timber is attacked by a fungus (Dcedalia vorax) 

 which excavates galleries throughout the wood similar in char- 

 acter to the "peck" in cypress. The timber is used chiefly for 

 fence posts, laths, shingles, cigar boxes, pencil stock, and the 

 best grade lumber for furniture and for mining and irrigation 

 flumes. 



It is associated with western yellow pine, sugar pine, Douglas 

 fir, western white pine and white fir {Abies concolor). The stand 

 per acre in California ranges from 500 to 2000 board feet per 

 acre. The stumpage value ranges from $2 to $3 per thousand 

 feet. 



The lumber cut of western cedars in 1910 was approximately 

 288,587,000 feet of lumber and 9,167,000,000 shingles. 



Sugar Pine. — Sugar pine {Pinus lamhertiana) is found chiefly 

 in southern Oregon and in California where it is an important 

 commercial tree. It never occurs in pure stands but is found 

 associated with western yellow pine, incense cedar and Douglas 

 fir on the lower limits of its range; and with white fir, red fir 

 (Abies magnifica) and the bigtree on the higher elevations. The 

 yield in the Sierras ranges from 2000 to 15,000 feet per acre 

 with a maximum of 60,000 feet. An occasional tree contains 

 54,000 feet. 



Sugar pine is especially prized for the manufacture of " shakes " 

 or spht shingles, and is also extensively used for fruit boxes, 

 match wood, sashes, doors and blinds, ship decking and interior 

 trim. The lumber is often substituted for that of eastern white 

 pine. The greater part is marketed locally, but it is also shipped 

 as far East as New England. 



The cut in 1910 was 103,165,000 feet. The bulk of the re- 

 maining stumpage is in the Sierras in California and ranges in 

 value from $2.50 to $4 per thousand feet. 



Lodgepole Pine. — This tree {Pinus contorta) is found from 

 Alaska to California and east to Colorado, and is used for mine 

 timbers, fence posts, lumber and crossties. The timber is small 

 and knotty and lumber sawed from it is suitable only for general
