TABLE 4. Volume in board feet of old trees of yellow poplar scaled by 

 Scribner Decimal C rule. 



In the conversion of cubic feet into cords of pulp wood closely piled, 

 peeled, dry and when the sticks are more than 12 inches in diameter, split, 

 the number of cubic feet of solid wood required to make a cord, varies 

 according to the diameter of the trees. Large wood piles more compactly 

 than small, consequently a cord of such wood contains a larger number 

 of cubic feet solid wood than a cord of wood from small trees. Table 

 5 shows the number of cubic feet of closely piled, peeled and split stem 

 wood to three inches in diameter in the top, required to make a cord.
