APPENDIX 
VOLUME TABLES 
The three volume tables most frequently used are given hereafter : 
(1) Total volume of tree in cubic feet, used mostly in technical work 
dealing with growth and increment; (2) volume in cubic feet to a 
5-inch diameter limit in the top, used in estimating cordwood or 
pulp wood; (3) volume in board feet to a 9-inch diameter limit in 
the top, used in estimating saw timber. The diameter limit is un- 
usually large, because aspen will not often be cut primarily for saw 
timber, but more valuable products will as a rule be taken from the 
tops. Xine-inch saw log utilization presupposes the utilization of 
the tops for props or pulp, with saw logs as a by-product.
