not of such good quality as
that of the common American hazel, and I have not succeeded in making
hybrids between this and other hazels as yet. The hazels are very
ancient in descent and each species likes to retain particular identity.

(52) A number of stocks of red birch, white birch and scrub oak grafted
with European hazels and chinkapins, but the grafts all died. The
grafting was done as an experiment in the hope that we might possibly
utilize our waste lands which are covered with birch and scrub oak by
grafting these trees with hazels and chinkapins. Some of the grafts
lived for such a long time and put out such long shoots that the
experiment will be tried again next year. It would not seem worth while,
excepting for the fact that it was a bad spring for grafting anyway, and
hazels did not even catch on hazels, though they caught freely last
year. The Japanese do grafting on stocks widely different from the
scions, but we have not developed that particular feature in this
country as yet.

(53) Asiatic tree hazels (_Corylus colurna_). This species makes a tree
as large as the common oaks and bears heavily. The nut is about the size
of that of the common American hazel. The tree is very beautiful, and I
am using it for grafting stock and for hybridizing.

(54) Sprouting cages. A double row of galvanized wire cages sunk four
inches into the ground and about four inches free above ground, filled
with sandy loam and used for sprouting any nuts which are to be employed
in experimental work. Each cage is fitted with a cover of galvanized
wire, the purpose of which is to keep out rodents which are so
destructive to planted nuts. In these cages there are now a large number
of hybrid nut trees growing, and they will be transplanted to permanent
sites or to the garden for culture next spring.

(55) Japanese heart nut (_Juglans cordiformis_). The tree is supposed by
some botanists to be a form of the Siebold walnut, but it has quite a
different appearance. It has an open habit with large leaves and nuts
which are suggestive of the conventional heart. The quality of the nut
is very good, much like that of the Siebold, but the nut is larger and
compressed. The tree is very hardy and is almost tropical in appearance.
It has not been planted very largely in this county, but it undoubtedly
will be eventually.

(56) Siberian walnut. The tree looks much like the Siebold walnut in
general appearance, but with smaller leaflets
