aise shade trees--trees around the home and pastures--and I
find there is considerable interest manifested in the last few years in
nut planting. The nut industry has a little mite of a start there in a
way--that is, there are a few seedling trees distributed from Logan on
the north to Arizona on the south. Seedling Persian walnuts fruit from
Brigham City on through Salt Lake and Provo, and practically all of the
nuts that are produced there in the state are of seedling origin. It is
reasonable to expect that some of the best grafted varieties will be
very much better. It seems to me that the state has every natural
condition for success in the production of nuts. If not in a commercial
way we can do a great deal to our advantage in planting nut trees as
shade trees. I simply want to let you know that there is a man out there
in the mountain section who is interested in nuts and going to help the
cause along.

THE DISEASES OF NUT TREES

M. B. WAITE, WASHINGTON, D. C.

In taking up the question of nut diseases it is hardly proper, perhaps,
to take too narrow a view of it and I will, therefore, mention some of
the other work being done here in Washington that is of interest to the
Northern Nut Growers Association.

You all know of the pomological work being done on nuts, and I hardly
need mention the work now being carried on by Mr. C. A. Reed, a member
of this association. It might be well to remind you that the work was
started by Mr. Van Deman some twenty-five years ago, and continued by
Mr. Corsa, and a report was issued some fifteen years ago. It was taken
up later by Mr. William A. Taylor.

The plant introduction work of Mr. D. G. Fairchild should be mentioned.
He is scouring the world for new nuts of all kinds for the northern and
southern, eastern and western United States, and introducing them into
this country. The diseases of those nuts are studied by Mr. Orton in the
Cotton Truck Division of our department.

Outside of the Bureau of Plant Industry also there is some work being
done on nut trees. The insects attacking cultivated nuts are studied by
Professor A. L. Quaintance, of the Bureau of Entomology, along with the
deciduous fruit insects. The insects attacking forest nut trees are
studied by Dr. Hopkins of the same Bureau in the laboratory that studies
the forest insects. Of course the nut trees, as forest trees, are
studied in the Forest Service about which you all know.
