THE RED SPRUCE.

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, jet 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.
