eason of 1933 made an adverse combination in some
localities. In the Ohio and Mississippi River Sections, the result was
disastrous to a large part of the crop. In those sections, May was an
exceedingly rainy month. June was equally hot and dry. It is in May that
the blossoming periods of most varieties of walnut occur, also it is
then that most of the nursery grafting is performed. Insofar as
pollination was concerned, there were probably enough hours of sunshine
during the blossoming period for the distribution of pollen to have been
adequate and effective. On some of the trees the rains came at just the
right time to wash practically all of the pollen to the ground. Had it
not been for later pollinating trees either of the same variety, or of
other varieties, or even of seedlings in the neighborhood, it is
probable that no nuts would have set. However the actual set was about
normal, but the heat and drouth which followed resulted in a drop which
took the greater part of the crop. A pecan grower in southwestern
Indiana, with between 300 and 400 grafted trees now of bearing age,
recently reported that in August he was unable to find a single nut in
his entire orchard. The result has not been quite as serious with the
walnuts. Nevertheless, the crop prospects are reported to be not at all
bright.

Nursery grafting in southern Indiana had literally to be performed
between showers. Sap flow was excessive and the resulting stand below
normal. The heat and drouth which followed killed outright many of the
scions which had begun to grow. Thus, in that section the orchardists
lost most of their crops and the nurserymen most of their grafts.

Walnut Relationships

In regard to walnut relationships within the genus, continued studies
have led to certain conclusions which would appear to bear mentioning.
One of these is to the effect that not all so-called "butterjaps" appear
to owe their origin to staminate parentage of butternut but that they
may be due to chance crosses of either Japanese walnut with Persian or
possibly black walnut, or quite as often to reversion to the true
Manchurian walnut, _Juglans mandschurica_.

Hybrids and Intermediate Forms

It is generally known that natural hybridity occurs so frequently
between almost any two species of _Juglans_ when growing together and
blossoming simultaneously that it is unwise to plant the seed of either
if pure types are desired. Intermediate forms, evidently betwe
