This hornbeam, 74 inches in girth in 1887, had a rate of 18 
for five years. Next year the increase dropped to 114, probably 
from the pruning before transplantation. After that operation 
in 1893 there was no increase in the first year, and it amounted 
to only 9 in the second, but for ten years thereafter the rate was 
20. The tree was then—1895—again transplanted, and the 
average of 1895-96 was only 2.

A companion of No. 81, originally in the south shelter belt, 
and even less in size, enh 6 inches in girth, its rate was 
only 134 as an infant, but after four years it increased for six 
years to 20, or the same as in No. 81. Transplanted in 1897, 
the increase fell from the high 214 of the previous year to 
3%, and the rate for ten years down to 1906, was only 5}, the 
minimum being o and the maximum 114. The foliage in this 
period has been scanty, but not unhealthy, and, as it is gradually 
filling up, the tree may yet do well.
