40 CHRISTISON—ADDITIONAL OBSERVATIONS ON 
I—EFFECTS OF TRANSPLANTATION. 
(a) Trees of a Considerable Size. 
1. Five trees of unusual size for transplantation were removed 
in the spring of 1896 from the Botanic Garden to the Arboretum. 
They varied between 3} and nearly 5 feet in girth, and along 
with them came a sixth of the more ordinary girth of 1 foot 
8 inches. One of the larger size, Pyrus Aria, failed to recover 
and was cut down in 1901, so that it may be left out of account. 
The rate of increase after transplantation of the other five is 
given in Table I. 
Although, on the whole, the aggregate rate is progressive, it 
has not been regularly so. Thus, it was rather less in the secon 
year than in the first, and it was considerably less in the sixth 
than in the fifth year. It was equal in the seventh and eighth, 
but decidedly less again in the tenth than the ninth.
