VOLUME TABLES. 
The volume tables for spruce which follow are divided between 
the various units of measure and comprise 12 board-foot tables, 
4 cubic-foot tables, and 3 cord tables. 
Board-foot tables. — The board-foot tables are all for old-growth 
spruce, except one of the Xew Hampshire tables, which is for old- 
field spruce. Since a different log rule is in use in each of the four 
principal spruce States, the data in each State has been worked up 
by the Scribner Decimal C rule for purposes of comparison. 
Of the four Maine tables two are based on the total height of the 
tree and two on the number of 16-foot logs, each according to the 
Scribner Decimal C and Maine log rules. 
The Xew Hampshire tables are five, one of which, Table 29, is for 
second-growth spruce. The old-growth volumes are given in terms 
both of the Xew Hampshire and Scribner Decimal C rules on the 
basis of total height and number of 16-foot logs. 
Both Xew York tables are according to the Scribner Decimal C 
rule, one of which is based on the total height of the tree and the 
other on the number of 16-foot logs. Although the Standard is not 
a board-foot measure at all, tables of volume in terms of Standards 
(Dimmick rule) on the basis of total height and of 16-foot logs are here 
included for purposes of comparison. 
The West Virginia tables are divided between the Scribner Decimal 
C and Doyle rules, each on the basis of the total height of the tree 
and on the number of 16-foot logs. 
Cubic-foot tables. — The cubic-foot tables (Xos. 38 to 41, inclusive) 
are all for old-growth spruce except Xo. 39 for Xew Hampshire, 
which is a combination of old-growth and '* old-field;' spruce. These 
tables being all for approximately the same utilization at stump and 
top, afford a good opportunity lor comparison of development in the 
different localities. According to the tables given, the diameters 
and heights run about the same for Maine and Xew Hampshire, but 
the Maine trees are generally fuller bodied, as indicated by a larger 
cubic content for the same diameter and height. Had the Xew 
Hampshire data been from the northern instead of the southern 
part of the State, it would doubtless have exceeded that in Maine in 
height and diameter and in volume as well. This is because spruce
