VOLUME TABLES No. 29. WASHINGTON RED CEDAR 

 BY THE SCRIBNER DECIMAL RULE 



TALL TIMBER 



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.
