THE BED SPSTJCE.

is generally believed to reach its New England optimum in northern 

 New Hampshire. For equal heights and diameters Maine shows 

 fuller-bodied boles than West Virginia, yet in general development 

 West Virginia greatly excels. 



Cordwood tables. — Old-field spruce is most commonly sold by the 

 cord for pulp, sometimes rough and at other times peeled. Hence 

 Tables 42, 43, and 44 were prepared for New Hampshire conditions, 

 where old-field growth is most prevalent. Table 43, based on 5-inch 

 utilization in the tops, was derived from Table 44 by interpolation. 

 Table 43 was used for scaling the sample plots for Table 17.
