THE BASIS FOR FOREST MANAGEMENT 43 
The area chosen for the study just described was at 
Santa Clara, Franklin County, New York. Here the 
first lumbering operations took place in 1882, the next 
in 1888 and 1891, and the final crop was removed in 1896. 
In 1882 probably only the largest and best trees were 
taken, and in consequence the number cut was small. 
At least it was not possible to find any small trees 
showing an increased growth from that date. The 
cuttings of 1888 and 1891 were much closer, and the 
effect on the small trees was very marked. 
In most cases the increased growth began with the 
first season after the cutting. On the areas cut over in 
1888 there were but a few trees which showed an ac- 
celerated growth beginning after that year. In these 
cases it was not possible to determine whether the new 
start had been delayed, or whether it was due to wind- 
falls following the cutting. On the area cut over in 
1891 a considerable number of trees showed a small 
increase in growth the first year, and a much more 
rapid increase the following years. In generalit may be 
said that the increased growth takes place, as a rule, the 
first year, and that it will in all probability continue until 
the next cutting, for ifthe first cause (the rapid decompo- 
sition of the humus) ceases after a few years, the roots 
and crowns will have begun to spread, and the second 
cause will thus have come into operation. 
The average rate of growth of 1593 trees in diam- 
eter on the stump is found in the following table. It 
was determined for all the trees together for the periods 
just before and after the previous cutting, and sep-
