46 CHRISTISON—ADDITIONAL OBSERVATIONS ON 
Girthing 7} inches when first measured in 1887, this com- 
panion of the last had the apparently high rate, for so young a 
tree, of 30 mil. for five years. Transplanted in 1892, it took 
three years to recover instead of one, as in No. 73. The 
recovery was complete, the rate rising for two years to 31°5 ; but, 
as the result of pruning and retransplantation in 1902, followed 
by a fungoid disease of the bark, the rate fell for the three years 
1902-04 to 44, and the tree had a very shabby appearance. The 
diseased bark was extirpated, and a cure apparently effected, as 
the appearance of the tree is much improved in the last two 
years, and the rate of girth increase has risen to 20.

The rate of this alder, 9} inches in girth in 1887, was 244, 
for three years, which seems good. It then fell off for the next 
six years to 154, and after transplantation in 1896 the tree did 
no good for four years and was cut down.

This birch, 94 inches in girth, promised to be a fine tree, 
having had a rate of 29 mil. for eight years before transplan- 
tation in 1895. In the previous year the increase was 313, but it 
fell to 2} in 1895, and after lingering on for two years more, with 
increases of 24, 114 and 5, the tree died in 1898.
