stand is somewhat depleted, conditions are favorable for a satisfactory 
restocking. . 
Plots 2 and 3 were tallied in a 15-year-old stand which promptly 
followed clear cutting. The area had probably not been burned 
over since the cutting and received no subsequent treatment. Chest- 
nut originally made up 30 per cent of the stand. The area now bears 
a dominant stand of 835 trees to the acre. In this stand class 1 
species lead with 65 per cent, and class 2 species comprise 19 per cent; 
only 16 per cent of the overstory is made up of undesirable species. 
Here also red oak and white oak are preponderant in the overstory, 
with smaller quantities of hickory, beech, gray birch, sweet birch, 
black oak, red maple, scarlet oak, largetooth aspen, white ash, sugar 
maple, and basswood, in the order of their abundance. The under- 
story contains 88 per cent of the total number of undesirable species. 
On the other hand it also has 1,075 trees of class 1 species, or 43 per 
cent of the total number, and 455, or 18 per cent, of class 2 species— 
more than enough to insure restocking with the better species. 
Plot 4 was tallied in a stand that had been thinned quite heavily 
in 1906. All the chestnut was removed in 1913; the oaks were left 
until 1921, when they, too, were cut. The resulting stand, on an acre 
basis, has a total of 2,590 saplings, at present receiving practically 
full light from above. Of these, 32 per cent are class 1 species, 54 
per cent class 2 species, and only 14 per cent class 3 species. Since 
red maple constitutes 34 per cent and dogwood 9 per cent of the 
overstory, cleanings or thinnings may be advisable to increase the 
proportion of the more desirable species in this stand. A similar 
operation in a permanent sample plot is shown in Figure 3. Scarlet 
oak, red oak, hickory, white oak, sweet birch, sugar maple, and beech 
follow in the order of relative abundance. These vary from 330 
scarlet oak saplings to 110 beech. Of the class 1 species 72 per cent 
are in the overstory. Of the undesirable species 53 per cent are 
already overtopped. In the overstory 60 per cent of the class 1 
species, 17 per cent of the class 2, and 19 per cent of the class 3 
species are of seedling and the remainder of sprout origin. The 
combination of desirable species and desirable (seedling) origin is 
particularly noteworthy. 
All the plots considered thus far fail to bring out clearly the nature 
and extent of replacement within the gaps left by the chestnut and 
the proportion of shrub or inferior species which may be taking the 
place of the valuable chestnut. To obtain this information 24 
square-rod sample plots were laid out and tallied in Connecticut in 
1924, and records were made of the forest-tree reproduction and of 
the larger or more abundant species of shrubs above 6 inches in height. 
Each plot was laid out so that the center of the clump of dead chestnut 
formed the center of the plot. Plots were tallied in four representative 
stands, varying from recently clear-cut stands (plot 4 above) to a 
60-year-old stand in which the merchantable chestnut had not yet 
been salvaged (plot 1 above). The records of these plots are sum- 
marized in Table 2. Attention should be directed to the fact, not 
brought out in the table, that the live chestnut sprouts seldom attain 
a diameter of more than an inch. The third and fourth generations 
of sprouts were being killed by the blight at the time the tallies were 
made. Two or three sprout generations may still be expected on the
