(U. S. Forest Service) 



Based on 1394 trees measured in logging operations in 

 Lane County, Oregon. Diameters, taken outside bark, 

 on the stump, which was ordinarily about 4 feet high, are 

 closely comparable with the diameter at breast height. 

 Trees scaled without deduction for defect or breakage, to 

 a point 10 inches in diameter at the top, unless unmer- 

 chantable to this point. The majority of the logs were- 

 24 feet long, though the length varied from 16 to 36 feet.
