PER CENT OF CULL AND WASTE. 
The average cull within merchantable dimensions, that is, for the 
portion of the trees from stump to 4-inch top, constitutes on the aver- 
age about 11.2 per cent of the merchantable yield. The top and 
stump form about 8.4 per cent of the total volume; the bark, 10.6 per 
cent. In other words, about 19 per cent of the total volume of the 
tree at present remains unutilized. Of the remaining merchantable 
part of the tree, 11.2 per cent must be allowed for cull.
