fungous enemy is
likely to follow it up, or if it is a weak species, brought into
activity by certain conditions, which will be brought back to its normal
mode of life again. I don't know that anything definite could be stated
till we know more about it.

Professor Craig: Perhaps Mr. Collins or Professor Reddick might offer
something in the way of suggestions on that.

Mr. Collins: I don't think that I have anything to propose beyond the
points suggested by the President. I think there are a good many points
which should be kept watch of, and I don't know any one that looks any
more promising than the other, except perhaps this of cutting out the
disease. But this is an expensive method.

Mr. Reed: Have you ever found any individual trees in infested districts
that were immune?

Mr. Collins: Only the Japanese, but I think Doctor Morris has found the
Korean even more immune. I shouldn't use the word "immune," perhaps, but
"highly resistant" to the disease. I have watched quite a number of
trees, in the midst of disease, which seemed to be resisting the
disease. I explained it in some cases by the fact that the bark was very
free from injury--maybe that was the reason why they did not take the
disease so easily as they might otherwise.

President Morris: The next paper will be that of Mr. C. A. Reed of the
United States Department of Agriculture on "The Present Status of Nut
Growing in the Northern States."

NUT GROWING IN THE NORTHERN STATES.

C. A. REED, Washington. D. C.

With the exception of the chestnut, no species of native nut-bearing
tree has become of prominent commercial importance as a cultivated
product in that portion of the United States lying east of the
Mississippi and north of the Ohio and Potomac Rivers. The growing of
foreign nuts has attracted greater attention than has the development of
the native species. Almost with the beginning of our national history,
the culture of Persian walnuts attracted considerable attention
throughout the East, especially in the States of the Middle and North
Atlantic Coast. The European and Japan chestnuts, the European hazels
and the Japan walnuts have since come into considerable prominence in
the same area.

Within the district so outlined, which comprises practically the entire
northeastern quarter of the United States, there are few sections of
large extent to which some species of native or foreign origin has not
already demonstrated its adapta
