The English walnut is not as hardy as the black walnut and is adapted
only to those sections where the peach can be grown successfully. At
present this tree cannot be recommended for any part of Ontario except
the Niagara district and the Lake Erie counties and even in these areas
it should not be planted unless it has been grafted or budded on the
hardier black walnut.

JAPANESE WALNUTS.

The Japanese Walnut is known to occur in Canada in three different
forms--Juglans cordiformis; Juglans Sieboldiana; Juglans mandschurica.

_Juglans Cordiformis._

This species is cultivated extensively in Japan and is the most valuable
one for Ontario. The tree is very beautiful, comes into bearing early,
bears heavily, grows rapidly and is reported to live to a great age. It
is believed to be as hardy as the black walnut and ought to do well
wherever the native walnut grows satisfactorily. In the best types the
nuts are distinctly heart-shaped, have a thin shell, crack easily and
contain a large kernel of good quality which can often be removed almost
entire from the shell with a light tap from a hammer.

There are two fine heartnut trees growing near Aldershot which is near
Hamilton on the road to Toronto. These trees are eight years of age and
are about twenty-eight feet tall with a trunk diameter of eight to nine
inches. In the seventh year one tree produced about a bushel of fine
nuts with thin shells.

_Juglans Sieboldiana._

This type was first introduced into the United States about 1860 by a
Mr. Towerhouse in Shasta County, California. Since then it has been
widely distributed and is now found in many parts of the United States
and Canada. It is much the same in appearance as the one first described
and grows just as rapidly and bears just as early but does not produce
so valuable a nut. The nut has a smooth shell of medium thickness with a
kernel of good quality. It does not usually crack easily and the kernel
cannot be taken out entire, therefore, is not so desirable as the
cordiformis type. In rapidity of growth the Japanese walnut is only
excelled by the willows and poplars. In the vicinity of Grimsby there is
a tree eight years of age which is about twenty-five feet high and has
trunk diameter of seven inches at the base. It began to bear nuts in the
third year and in the sixth year produced one bushel.

_Juglans Mandschurica._

The general growth characteristics of this species are somewhat similar
