Fig 1. gives a fair idea of the extremes in size of the Japanese
chestnut. Since the smaller size is probably close to that of the wild
chestnut in Japan, the figure illustrates what has been done by the
centuries of selection and cultivation that the chestnut has undergone
in Japan.

[Illustration: Fig 1. Nuts of _C. crenata_, Japanese chestnut, showing
approximately the limits of size in the species. Left: from a tree on
Long Island, N. Y, owned by Mr. John Vertichio. Right: from one of our
forest type Japanese trees given to us by the Office of Forest Pathology
in 1930 and now growing at the Sleeping Giant Plantation, Hamden, Conn.
The tree is probably representative of the wild type of nuts in Japan--a
little larger than the native American chestnut. However, it is probable
that smaller nuts of the Japanese species exist. About 1/2 natural size.

Anent the large nuts in the photograph, which weigh about an ounce
apiece or about 28 g. (compare figures in table I), Mr. Ferguson,
Instructor at the Long Island Agricultural and Technical Institute,
through whom we received the nuts, states that "the nuts of the
seedlings from the tree do not average better than half the size of
those of the parent tree." This illustrates the fact, now well known,
that the chestnut tree is self sterile. Nuts are always (with
exceptions) a result of fertilization of the flowers with the pollen
from _another_ tree.

We should like to reproduce this tree in our plantations, but the only
way it can be done is by grafting scions of it on to some other,
preferably Japanese, stock, or by rooting cuttings from it--a method
which we still have not been able to accomplish readily.
