Based on 1440 trees, in both pure and mixed stands, 
measured at logging operations at various points in west¬ 
ern Washington. A stump height equal breast diameter 
allowed. Trees scaled in 16-foot log lengths (with trim¬ 
ming allowance) to a diameter inside bark of 8 inches. 
No deduction for defect or breakage. 
Actual utilization a little over 80 per cent of above 
figures. 
The true firs are formed very nearly like hemlock.
