It was prepared for transplantation by pruning and cutting 
round the roots in autumn, 1894, when 3 feet 8 inches in girth, 
and quite retaining its handsome look; but it was allowed to 
stand for five years more, the pirtninicreasé rate falling to 4 mil.’ 
In 1899 it was removed to the south walk of the Arboretum, 
when it was noted that a great mass of roots had formed in the 
ball of earth. But the increase since the operation has fallen 
almost to zero. and the tree is a complete wreck, though still 
allowed to stand. This result was doubtless mainly caused by 
the tree having been twice blown down after transplantation. 
On the second occasion the holding stays were broken, and the 
tree torn out of the ground, the roots being broken across, and 
the soil shaken from them. - 
For the next ten years the rate was 
(6) Trees of Smaller Girth.

Transplanted in spring, 1887, to an open grassy space, where 
it still stands, quite free, but well sheltered. When transplanted 
it was an infant, girthing only 62 inches. Since then it has only 
been interfered with by pruning to promote upward growth. 
The rate of increase before transplantation is unknown, but 
ought to have been, and no doubt was, much above the 5 mil. of 
the following three years. In the next year the amount sprang
