is not blighted, and
very few that are not dead. Now, in the midst of this disaster, what was
the behavior of my experimental chestnuts of various kinds? It was this.
I had about one thousand Koreans that lived up to five years of age,
growing in the midst of blighted chestnuts, and none of these blighted.
It occurred to me that it might be well to graft these on the stumps of
American chestnut, because these Koreans resisted the blight; but when I
grafted them on the sprouts of American stumps, at least fifty per cent
of the Koreans blighted, showing that the pabulum wanted by the
_Diaporthe_ seemed to be furnished by the American chestnut. I had some
chestnuts from North Japan that resisted the blight, and yet these
grafted on the sprouts from American chestnuts blighted. I had some
Chinese chestnuts, and none of those have blighted as yet; and in
grafting them, two or three have not been blighted. I have perhaps
twenty-four chinquapins, both the western form and the eastern, and only
one branch of one tree has blighted. Of the southern Japanese chestnuts,
very many are blighted. They are not as resistant as the northern. I
have a good many chestnuts of European descent, and among these some
resist the blight pretty well; and some of the American progeny, like
the Hannum and Ridgely, seem to resist well enough, so that now I am
grafting these upon many different sprouts. This should be worked out,
and I wish to know what men have tried experiments along this line. I
would like to ask Professor Reddick to discuss this question.

Professor Reddick: I have very little that I can add at the present
time. The points the talk has raised here are of the greatest
importance, and there is certainly room for a great many people to work,
though here in this state we have only one man who is devoting his
attention particularly to this disease. I find in connection with the
work that Professor Collins is doing, and in connection with the
Pennsylvania work, that there are some people engaged on these very
vital and important problems. They are not giving any particular
attention to field work, but are working on these special problems. I
think you all appreciate that progress of investigations on this kind of
subjects is rather slow, and in the meantime the man who has his trees
and his nurseries blighting is surely up against it.

I have only one thing in mind, a thing which I suggested to Mr. Rankin
when he first started on this
