Advantage of Grafting Certain Trees. 397 
tion, in the beginning of the present month, [January, 
1807]. 
Both the walnut and mulberry tree succeed so ill when 
grafted, unless by approach, that I can scarcely recom- 
mend attempts to propagate them in any other way : but 
when they succeed by other modes of grafting, nearly 
the same advantages will probably be obtained : the ha- 
bit of the bearing branch is, however, least disturbed by 
grafting by approach. 
The Spanish chesnut succeeds readily when grafted 
in almost any of the usual ways, and when the grafts 
are ta,ken from bearing branches, the young trees afford 
blossoms in the succeeding year : and I am much inclined 
to think, from experiments I have made on this tree, that 
by selecting those varieties which ripen their fruit early 
in the autumn, and by propagating with grafts or buds 
from young and vigorous trees of that kind, which have 
just attained the age necessary to enable them to bear 
fruit, it might be cultivated with much advantage in this 
country, both for its fruit and timber. 
T have tried similar experiments on many other species 
! of trees, and always with the same result; and I enter 
tain no doubt, that the effects of time might be thus anti- 
cipated in the culture of any fruit, which is not produced 
till the seedling trees acquire a considerable age. For I 
am thoroughly confident, from very extensive and long 
experience, that the graft derives nutriment only, and not 
growth, from the young stock in which it is inserted ; and 
1 that with the life of the parent stock the graft retains its 
I habits and its constitution.
