from famine or repletion. For this reason, a 
deciduous plant cannot be grafted on an ever¬ 
green, and the reverse. The necessity of a 
conformity in the habit of growth, is strik¬ 
ingly displayed in Mr. Loudon’s Arboretum 
Britannicum, in a flowering ash grafted 
on a common ash; by which it is shown, 
that an architectural column with its plinth 
and capital may be formed in a living tree, 
where there is a decided difference in the 
growth of the stock and the scion. 
These examples show that no intimate 
union tak;es place between the scion and the 
stock; and the fact is, that though they 
grow together and draw their nourishment 
from the same root, they are in every other 
respect perfectly distinct. The stock will 
bear its own leaves, flowers, and fruit, on 
the part below the graft; while the scion is 
bearing its leaves, flowers, and fruit which 
are widely different, on the part above the 
graft. Nay, five or six grafts of different 
species on the same tree, will each bear a 
different kind of fruit at the same time. This 
want of amalgamation between the scion and 
the stock is particularly visible in cases of
