APPENDIX. 3 



VOLUME TABLES. 



BOARD-FOOT VOLUMES. 



The following tables give the average volumes in board feet of forest-grown beech, 

 basswood, yellow birch, and sugar maple trees of different sizes, in terms of the number 

 of possible 16-foot logs and half logs in the tree. Since among trees of the same size 

 some will be straight and Usable to a small diameter at the top, while others break up 

 into branches at considerably larger diameters, the Lake States measurements were 

 separated on this basis, and appear in three tables, headed maximum, average, and 

 minimum utilization. The tables from the other regions represent only the average 

 utilization. 



The tables were prepared by the Scribner Decimal C rule, and show in each 

 case the stump height, top diameter limit, and number of trees on which they are 

 based. "Diameter breast-high" is the diameter at a height of 4J feet. The tables 

 are based on measurements of sound trees of normal shape only.
