C SPECIES OF CHESTNUTS.

Inasmuch as very few of the Chinese, Japanese and European chestnuts
have been planted in Ontario very little can be said regarding their
behaviour. Dr. Sargeant reports the Chinese chestnut (Castanea
Mollissima) as being hardy at the Arnold Arboretum and therefore it
should be adapted to southern Ontario. The Japanese chestnut is also
quite hardy but is susceptible to chestnut bark disease. A few Japanese
chestnut trees are growing near Fonthill, Ontario, and have borne some
good crops. The tree is a small, spreading grower, comes into bearing
fairly early and bears quite heavily.

THE HICKORIES.

There are four species of Hickory native to Canada. The shagbark, the
bitternut, the pignut and mockernut.

The shagbark hickory (Carya ovata) is the chief one of value for the
production of edible nuts. It is confined to the St. Lawrence valley
from Montreal westward and along Lakes Erie and Ontario for a distance
of 40-50 miles back from the shore. It reaches a height of fifty to
ninety feet and a trunk diameter of one to three feet and grows best on
deep, fertile loams.

BITTERNUT HICKORY (_Carya cordiformis_)

This species has a wider range than the shellbark and is found in
southwestern Quebec and throughout Ontario from the Quebec border to the
Georgian Bay district. It grows best on low wet soils near streams but
is also found on higher well-drained sorts. There are two fair sized
trees on such a soil on the O. A. C. campus. This species may prove to
be of value as a stock for grafting with the shellbark kingnut and some
of the good hybrid hickories.

The mockernut (Carya alba) and the pignut (Carya glabra) occur along the
north shore of Lake Erie and along Lake St. Clair.

The mockernut is not of much value as a nut tree but the wood is
considered to be superior to other species of hickory.

The pignut is generally a small tree which produces nuts of variable
size, form and flavor. The kernel may be bitter or it may be sweet and
the nuts vary from round to pear-shape.

THE HAZELS.

There are two species of hazels native to Canada--the common hazel
(Corylus Americana) and the beaked hazel (Corylus cornuta). The hazels
have a wider range than other nut-bearing plants in Canada, being found
in almost every province from Nova Scotia westward to British Columbia
and as far north as Edmonton in Alberta and Prince Alberta in
Saskatchewan. In Ontario the beaked hazel grows as far n
