in some warmer climate, either in Oregon, Missouri or New York. This
would determine their value as semi-hardy trees worthy of propagation in
such localities. Such an experiment will probably be made eventually.

The same year, 1937, in which I obtained the Polish nuts, I also bought
one hundred pounds of Austrian walnuts, to serve as a check. Eighty
pounds of these consisted of the common, commercial type of walnut,
while the remainder was of more expensive nuts having cream-colored
shells and recommended by the Austrian seed firm as particularly hardy.
Altogether these nuts included approximately one hundred varieties,
twenty of which were so distinctive that their nuts could be separated
from the others by size and shape.

About two thousand seedlings grew from this planting, most of which
proved to be too tender for our winter conditions. The seedlings grown
from the light-colored nuts show about the same degree of hardiness as
the Carpathian plants. Many of them have been set out in experimental
orchards to be brought into bearing.

After the first year, the English walnuts progressed fairly well. Large
trees, which had not been entirely worked over at first, were trimmed so
that nothing remained of the original top, but only the grafted
branches. The winter of 1938-39 was not especially severe and mortality
was low, although it was apparent that all of the varieties were not
equally hardy. Even a few of the scions grafted on butternut stocks were
growing successfully. I had made these grafts realizing that the stock
was not a very satisfactory one, to learn if it could be used to produce
scionwood. As the results were encouraging, I decided it would be
worthwhile to give them good care and gradually to remove all of the
butternut top.
