Basis, 711 trees measured by T. S. Woolsey, jr., in Grafton County in 1903. 

 One cord of stacked wood equals 96 cubic feet of solid wood and bark. 



TAPER MEASUREMENTS. 



Changing economic conditions, due to invention, increasing demand, 

 and decreasing supply, cause corresponding changes in logging prac- 

 tice and mill utilization. It is essential that we have some means 

 readily available by which volume and other tables may be revised 

 or new ones made as these changes take place. Taper tables afford 

 such a means by showing for each 10-foot height class and each 1-inch 

 diameter class (breastheight diameter measured outside the bark), 

 the diameter inside the bark at 1-foot intervals from the ground up to 

 4.5 feet (breastheight), and at 8.15-foot intervals above a 1-foot 

 stump height. The allowance of 0.15 of a foot at each 8-foot section 

 is for loss in trimming at the mill. The taper tables (Tables 45 to 49) 

 for each of the four States are all for "old-growth" spruce, except 

 Table 46, which is for "second-growth" or "old-field" spruce.
