I have one particular variety of American chestnut that I think a great
deal of. It was one of the first trees to go down from the blight. Stump
sprouts from this tree I have grafted on other stocks, on the common
American, and recently on chinquapin. The sprayed ones are all alive;
the unsprayed ones are not alive. Now, that is a matter of locality,
perhaps.

THE PRESIDENT: Dr. Morris, I detect a possible explanation for
difference of results. Mr. Hunt's trees were sixteen or seventeen years
old. Dr. Metcalf tells us, however, that young trees are relatively
immune. How old are yours?

DR. MORRIS: Not over twelve years. No grafts on them over four years.
That would make a difference.

MR. LITTLEPAGE: Well, Mr. Hunt did a good job of spraying. I saw his
trees, and they were saturated.

MR. WEBER: Do they ever use a sticker in the Bordeaux?

A MEMBER: What preparation of Bordeaux mixture do you use, Dr. Morris?

DR. MORRIS: I use a commercial preparation called Pyrox.

MR. CARL J. POLL: Will the chestnut blight attack any other trees
besides the chestnut?

DR. METCALF: Outside of the chestnut genus, that is, the genus Castanea,
the disease goes on to a few other trees. A curious fact is that it will
go on to the sweet gum, a tree not related at all, and it will go on to
a few oaks, in no case enough to seriously damage them as it does the
chestnuts, but enough so that those trees can easily be carriers of the
disease.

THE PRESIDENT: I think we might pass from this funeral. We have a paper
by Dr. Van Fleet, whose work, I suppose, is known to everybody here. The
paper has been prepared by Dr. Van Fleet and will be read by the
Secretary.

HYBRIDS AND OTHER NEW CHESTNUTS FOR BLIGHT DISTRICTS.

DR. WALTER VAN FLEET, WASHINGTON, D. C.

The sinister spread of chestnut blight, as the bark disease caused by
the fungus _Endothia parasitica_ is popularly called, within little more
than 10 years, from its place of apparent origin near New York City into
13 states, practically reaching the eastern and northern limits of our
native chestnut stands, and sparing in its course no individual trees
exposed to infection, has about convinced even the most optimistic
observers that without the intervention of natural checks the American
chestnut as a forest asset will soon pass away. There is no present
indication of diminution in the virulence of the fungus parasite and
little reason to hope its progress as a t
