It will be seen that the original average was exceeded by the 
final average in 6 cases; that these two averages were nearly 
equal in 5 ; and that the final fell decidedly below the original in 4. 
In general, the appearance of a tree is an index to the degree | 
of its recovery of girth-increase, but not invariably. The 
American oak, No. 61, is a remarkable exception. The year 
after transplantation the foliage was very scanty, and next year, 
in consequence of the death of the young twigs, there was no 
foliage, but in the following year there was a slight improvement, 
and in the next the recovery both of foliage and girth-increase 
was complete.
