Figure 3, based on measurements of 34 well-stocked shortieaf pine 
stands in Arkansas, represents graphically the proportion of clear 
length to crown length for trees of various heights on the better and 
poorer quality of situations. 
The lengths of the crown and clear stem and their proportion of 
the total height of the tree are given in Table 3. In New Jersey 
70-year-old stands 65 feet high had practically the same actual depth 
of canopy as vigorous stands 50 years old and 80 feet in height in 
Arkansas. The proportion of clear length to total height in New

Fig. 3. — Relative proportions of clear length and crown depth for shortieaf pine of various heights on better 
and poorer qualities of site in Arkansas. 
Jersey was about 48 per cent, as compared with 70 per cent for the 
better stands in Arkansas.

CROWN SPREAD AND TREE DIAMETER. 
In well-stocked stands of shortieaf pine a very close relationship has 
been found to exist between the diameter of the tree at breast height 
and the diameter of the crown. This relationship is striking in its
