2 The "log" volume is the solid contents of wood and bark between an average stump height of 2.4 feet 

 and the "diameter inside bark of top" shown in the eighth column. The volume of "top" is that con- 

 tained 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 50- inch stick.

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 fourteenth 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 17 per cent of the total volume; there was no consistent variation with the size of 

 the tree.
