All trees — spruce slope tvpe. 
This table is a combination of growth- diameter Table 11, height Table 4, and volume Table 41. 
Data collected by John Foley in 1903 in Greenbrier County. 
While similar data are not available for either Maine or New Hamp- 
shire, a comparison of the " Lower spruce and hardwood" and even 
of the " A verage-of -all-type" values of Maine (Table 9) with the 
"Average" values of New York (Table 10) indicates a better average 
development in Maine than in New York. Adequate figures for New
