The above and following table; are based on field 
measurements of about 1200 sound and normal trees 
grown in fully stocked mixed stands in the Puget Sound 
region, at elevations from 200 to 1000 feet, by A. G. Jack- 
son of the U. S. Forest Service. Scaled from taper meas¬ 
urements in 32-foot logs to diameters stated. Data 
arranged to promote timber grading. 
Cedar scaled in short lengths, if at the same time it is 
sound, of good form, and fully utilized, will yield more 
than these values. On the other hand the tree is so 
largely subject to swell butt, rot and breakage, that tables 
must be used with great caution and often discarded 
altogether.
