to the other two types but the nut, however, is quite different, being
somewhat like a butternut. Because of this it is sometimes called the
Japanese butternut. It is the least desirable of the Japanese group and
should not be planted except where the cordiformis type will not grow.

CHINESE WALNUTS (_Juglans regia sinensis_).

The Chinese walnut is being grown experimentally in the northern part of
the United States and has been tried at only one place in Canada, e.
g., in the grounds of G. H. Corsan, Islington, Ont. The tree is reported
to be fairly hardy at the Arnold Arboretum, Jamaica Plains, Mass., and
should be sufficiently hardy for southern Ontario. It is believed that
the Chinese walnut will prove to be hardier than the English walnut and
it may have an important place amongst the trees in the northern part of
the United States and in Southern Canada. The nuts are quite large and
have a shell which is thicker than the English walnut but not nearly as
thick or hard as the native black walnut. The kernel generally has a
fine flavour, being almost as good as the English walnut. Nuts of this
species have been planted at the Ontario Agricultural College, Guelph,
and at the Experiment Station, Vineland, Ont., and it is expected that
trees will be hardy enough for our climate and produce nuts which will
be as good as the Persian walnut.

THE SWEET CHESTNUT (_Castanea dentata_)

The sweet chestnut is found growing naturally on sandy ridges in that
part of Ontario extending from Toronto to Sarnia and southward to Lake
Erie. At the Central Experimental Farm, Ottawa, there is a fair sized
tree and near Newcastle there are a few fine specimens.

It grows to a large size, sometimes reaching a height of one hundred
feet and a diameter of five feet at the base. When grown in the open it
forms several heavy branches and makes a broad rounded crown, but when
grown in a dense stand it makes a tall, straight tree.

The native chestnut is subject to a fatal disease called chestnut bark
disease. This disease is not known to occur in Ontario, but there is no
assurance that it will not appear and, therefore, the planting of this
tree is attended with some risk.

A dwarf type of chestnut has been reported from east of Ottawa in the
Ottawa valley. The tree is about fifteen feet tall and produces a small
burr containing only one nut. I have not seen this tree so cannot vouch
for the accuracy of the above statement.
