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 New 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 New 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 New Hampshire and Scribner Decimal C rules on the 

 basis of total height and number of 16-foot logs. 



Both New 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 (Nos. 38 to 41, inclusive) 

 are all for old-growth spruce except No. 39 for New Hampshire, 

 winch 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 for comparison of development in the 

 different localities. According to the tables given, the diameters 

 and heights run about the same for Maine and New Hampshire, but 

 the Maine trees are generally fuller bodied, as indicated by a larger 

 cubic content for the same diameter and height. Had the New 

 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
