seldom
filled.

Twelve seedling Chinese chestnut trees from different sources have been
planted, and an area of several acres has been set aside to extend the
work on chestnuts.

A start has been made toward a collection of filberts. Five named
varieties of European filberts were planted in 1947. All have suffered
from winter injury, but only one tree has been killed outright. Very few
nuts have been produced. About 25 seedlings of European filberts and 25
of the American were received from Tennessee two years ago. About 90%
have survived and are growing nicely.

Several other species of nuts have been tried without success. Two trees
of the red hickory were set out several years ago, but they failed to
leaf out. Four young trees of the golden chinkapin of the Pacific Coast
were planted and grew well the first summer, but all four were killed by
the first freeze in the fall. About a pound of nuts of the Turkish tree
hazel were planted several years ago; these failed to come up the first
year. The next winter the mice and rabbits discovered them and ate up
most of the planting. A few germinated, but most of these were lost in
transplanting, and today only two are left of the entire lot.

Discussion

MR. SHERMAN: I'd like to say, just before you leave this subject, that
the speaker barely mentioned the fertilization experiment that was
started in Pennsylvania on black walnuts. I think the members of the nut
survey stuck their necks out and got their heads hit a little bit when
we said that the black walnut as an orchard industry in Pennsylvania was
sick. We hadn't been able to find crops of black walnuts. We found
individual trees, but we couldn't find orchards of black walnuts, and as
a result of that, this fertilization experiment was started, in a
55-acre black walnut orchard with Ohio, Stabler and Thomas varieties.

The owner, Truman Jones, said, "I don't care what you do with the
Stablers, you can't hurt them, anyway; they are no good to begin with."
But this orchard, evidently from all outward appearances, has been
growing very slowly for quite a number of years. It isn't the size it
should be, and we think the main trouble there is lack of fertility, and
that's the reason why this fertilization experiment was started.

It's quite an ambitious experiment. It takes in about 93 trees in the
center of a 55-acre planting of black walnuts. They haven't had a c
