 inside bark, small end (Timson 1912)^-^'^ 



•W = 66.0433 - 6.8790D + 0.3433D2l. 



^Line encompasses weight based on 90 percent of the logs measured; values outside the dark line 

 are based on the remaining 10 percent of the field samples. 



^Study was conducted at six mills in Maryland, West Virginia, and Virginia and included a total of 

 4,800 woods-run logs representing 15 commercially important Appalachian hardwood species.
