Poland or western Russia and north China. These varieties have
not been widely distributed in this state and it may be found that even
these will have a limited range in Michigan. Their behavior, however,
shows that they are somewhat hardier than varieties from western Europe
or England. Unfortunately the supply of trees of these apparently hardy
kinds is limited and it will take some time to work up a stock of the
best strains. In the meantime, those who desire to plant the English
walnut had better wait until a supply of the hardier kind is available
or plant some other hardy species such as the black walnut.

(2) Thoroughly drain all soils intended for nut trees. Well drained
soils favor good root development and seem to lessen late growth, thus
reducing to a slight extent at least the severe killing back that is
noticeable on such growth.

(3) Use nitrogenous fertilizers in moderation.

Fertilizers rich in nitrogen may stimulate the late growth and
predispose the tree to killing back.

(4) Do not cultivate the soil around nut trees late in the summer.

Late cultivation stimulates late growth and prevents the trees from
properly ripening their buds and wood. This late growth invariably
suffers more severely from winter cold than growth that is well matured.

Nut Tree Prospects in the Tennessee Valley

This is a vital question to discuss in the economic welfare of any
community, but the sooner the value of tree crops is recognized, the
sooner will the agriculturists be on a more simple economic basis and I
feel that the members of this association agree with me when I say that
the Tennessee Valley Authority Board of Directors should be complimented
by this body for their foresight in making tree crops a part of their
economic scheme. In my five months of work the points that I believe are
of most interest to this body are that I have actually made a cursory
tree crop survey of the whole Valley--fifteen hundred miles long and
seventy-five miles wide. This is the first time this kind of work has
ever been attempted in the world on an extensive scale. The results of
this survey have been approximately the following:

(1) A keen interest by all the County Agents in the tree crops question.

(2) I was astonished at the surprising number of County Agents that had
been advocating nut trees as a farm asset
