Apr. 1, 1927 Natural Replacement of Blight-Killed Chestnut 639 
A study of Figure 7, a sketch of the crown spread of the trees on 
permanent plot 320 in 1904, and Figure 8, a sketch of the same plot 
in 1924, clearly shows that the chestnut has completely disappeared 
from the dominant part of the stand, and that the crown cover of 
the dominant stand is already almost completely closed. From the 
standpoint of crown closure, this plot shows exceptionally good re-

Fic. 7.—Crown spread of trees on permanent sample plot N: 
covery. The amount of red maple in the upper crown cover of this 
stand is above the average for otherwise similar stands. Its prepon- 
derance is probably due to the fire which lightly burned over the 
area a few years after cutting. The fire favored the increase of red 
maple in the overstory, and dogwoo ; 
on sites of second quality, similar to this area, 
less aggressive than it is on the better sites (10). 
The decrease in the number of trees on most of 
plots is due not only to the loss of chestnut, but also to the rem
