of Mont Alto, at an altitude of about 1000 feet, near the
location of the State Forestry School of Pennsylvania, another tree said
to be 65 years old, and having a girth at breast height of 65 inches, on
the residence grounds of Mr. H. B. Verdeer, is apparently as hardy as
are the indigenous species of the neighborhood. It is claimed to have
recently borne three pecks of nuts in a single season, and it now has a
very good crop. Numerous other instances of pecan trees in the North
might be cited, but these suffice to establish not only the uncertainty
of hardiness of the pecan in the North, but also the probability of nut
crops in occasional years or oftener, well beyond the generally accepted
range of the species.

The hardiness of the Persian walnut is difficult to define. To again
quote Dr. Waite, "_Juglans regia_, as we know it in the east and north,
frequently succeeds over long intervals of time under conditions of
climate, soil, elevation, and general environment suitable for the
peach. It is perhaps a trifle more subject to injury by radical drops in
temperature, but it recuperates with decidedly greater difficulty." Dr.
Waite points out that there is a striking similarity between the
requirements of local environment of the Persian walnut and the sweet
cherry. It develops that this is a familiar comparison in southwestern
British Columbia. Both require good drainage of air and soil, or the
benefit of moderating influence such as is afforded by large bodies of
water. Also both are endangered by warm spells during the dormant
months.

These statements cover the situation quite correctly, as it is seen by
the writer, although it might be added that beyond or west of the Ohio
River, in the middle portion of the country, this species is seldom able
to survive for more than one or two winters. Many trees have been
planted in Michigan, but the great majority have passed out entirely
even where peaches normally succeed. However, it is the experience of a
few growers in Sanilac County, bordering Lake Huron, that within a half
mile of the lake, there is a greater profit in Persian walnuts than in
peaches. One grower at Lockport, New York, has found Persian walnuts to
pay better than other orchard crops which he has raised at equal expense
or upon equal areas of land. An orchard at East Avon, widely known at
one time and visited by the Northern Nut Growers' Association in 1915,
practically succumbed entirely after having
