pear on the same tree from time to time, season 
after season, and in due course the flowers are 
replaced by growing nuts, so that there is a regular 
succession month after month. 
This habit of perpetual bearing, manifested by 
a tree that ordinarily produces its flowers and in 
turn its nuts at fixed seasons, is perhaps scarcely 
less remarkable than the habit of early bearing. 
Doubtless the two are genetrically associated. 
CHESTNUT SEEDLINGS 
The care of the chestnut seedlings presents no 
important complications. 
My general plan in selecting seedlings for 
further tests is the same employed in the selection 
of seedling fruit trees. Prominent buds, large 
leaves, thick, heavy twigs, almost invariably fore- 
cast large, fine nuts. There is, however, an excep- 
tion to be noted in the case of the Japanese chest- 
nut, which has smaller leaves. It is necessary to 
bear this in mind in dealing with seedlings that 
have a Japanese strain. It is needless to say that 
the capacity to select the right seedlings for preser- 
vation is highly important, as an element in saving 
time and expense in the practical development of 
improved varieties of chestnuts. 
I have already referred to the saving of time 
that may be accomplished through grafting the 
chestnut seedlings instead of waiting for them to
