THE COMMERCIAL HICKORIES. 

 TABLE 12. Taper of stem of hickories Continued. 



Table 13 shows contents, in cubic feet, of logs of different lengths 

 by diameters at the small end. It is based upon the taper measure- 

 ments given in Table 12. It is an accurate log rule and can be used 

 equally well in buying and selling large and small logs, and spoke 

 and handle or pole and shaft or sucker-rod material. The Forest 

 Service in Bulletin 36, "The Woodsman's Handbook," recommends 

 that all log rules should be standardized by computations based 

 on the diameter at the middle of the log. In the case of hickory, 

 however, the rule based on diameters at the small end has some 

 advantages.
