THE GIRTH-INCREASE OF DECIDUOUS TREES. 57 
that size is not excessive, as only one tree of the five perished. 
But if we take the hawthorn, No. 16, transplanted in 1899 and 
now standing without hope of recovery, the proportion of 
deaths is more serious. 
In every instance recovery, both in appearance and in the rate 
of girth-increase, was slow. None of these trees could be- 
regarded as healthy looking and handsome till from eight to ten 
years had elapsed ; and one, although by no means in a desperate 
condition, has still very scanty and ill-developed foliage, while 
another has scarcely any at all. As regards girth-increase, 
none of the trees have regained the rate that might be expected 
from their size. In three it is still very deficient, and in two of 
these girth-increase has either scarcely or not at all begun. 
Probably the risk of failure increases with the size of the tree ; 
but, of course, the number experimented on is too small to 
warrant a conclusion on this point. . 
The final results, both in regard to appearance and girth- 
increase, in this group have still to be ascertained, and it will be 
very interesting to watch future developments. 
Small Trees—In all, 29 trees were transplanted, thirteen of 
them twice, making 42 actual cases.

The period of depression after transplantation varied con- 
siderably. 
It lasted one year in Nos. 7, 18, 22,67, 69 (2nd time), 73 (2nd 
time), — 
two years in Nos. 1,9, 21, ae (2nd time), 69 (twice), 
77, 79, 81 (2nd time), 85 ; 
three years in Nos. 2, 8, e 80 (twice), 94; 
four years in Nos. 16, 75. 
The deficit in the girth-increase of trees that recovered fell to 
zero in 18, 69 (twice), 81, 85. 
Average of 2 to 3 mil. in 1, 2, 8;
