BULLETIN" 285, U. S. DEPARTMENT OF AGRICULTURE. 



CUBIC-FOOT VOLUMES. 



These tables give the average volumes in cubic feet of forest-grown yellow birch, 

 beech, sugar maple, and basswood trees of different sizes. They are based on stem and 

 branch taper measurements of the trees from which the preceding board-foot tables 

 were made. The volumes are shown separately for "logs" and "topwood." The 

 cubic-foot volume of "logs" includes the stem of the tree between the same stump 

 heights and top diameters as for the board-foot tables, except that for the Lake States 

 tables only the "average" top diameters were used. The volume of "top" is for the 

 portion of the main stem above the upper diameter given, plus the solid volume of all 

 branches suitable for cordwood to a minimum diameter of about 2 inches outside 

 bark at the middle of a 5-foot stick, except for basswood, the branches of which were 

 measured to a minimum middle diameter of 4 inches. 



The tables for the Lake States also give the per cent of bark based on the cubic 

 volume of the stem with bark. For basswood and beech the per cent of bark varied 

 consistently with breasthigh diameter; for birch and maple there was no consistent 

 variation. 



Table 37 gives the cubic volume of red maple on the Harvard Forest, Petersham, 



Table 31. — Yellow birch in the Lake States, 1 volumes in cubic feet.

2 The "log" volume is the solid contents of wood and bark between a stump height of 1 foot and the 

 "diameter inside bark of top " shown in the 14th column. The volume of "top" is that contained in the 

 stem above this point, and in addition all branches suitable for cordwood having a diameter, outside bark, 

 of 2 inches or more at the middle of a 5-foot stick. The entire volume of trees too small to yield a 6-inch log 

 is considered topwood. Bark comprises about 13 per cent of the total volume; there was no consistent 

 variation with the size of the tree.
