Based on 289 trees cut for pulp wood. All diameter 
measures except diameter breast high taken on the wood 
surface after peeling off the bark. Original figures in 
cubic feet, converted into cords at the ratio of 90 cubic 
feet solid wood per cord.

From study by Harvard Forest School on oak thinnings. 
Wood used up to 2 inches in diameter. 80 cubic feet 
solid wood per cord. 
The study showed that when the bolts from the trees 
3 to 5 inches in breast diameter were piled by themselves, 
there were 250 bolts and 67 cubic feet in a cord; wood 
from the 5- to 7-inch trees piled together gave 173 bolts 
and 79| cubic feet; from the 7- to 9-inch trees, 133 bolts 
and 91 cubic feet.
