*Volumes computed according to Schiffel: V = (.16B .66b)h, where, 
V = Volume. 
B = Basal area of cross section at breast height. 
b = Area of cross section at middle height. 
h = Total height of tree.

It must be remembered that these figures are based on trees growing 
under an entire absence of management. Proper management should easily

drawn for the maximum growth in diameter at the stump showed the follow- 
ing comparison:
