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 timber destroyer can be stayed by any agency in the control of man. Already the losses, direct and indirect, occasioned by chestnut blight are computed as high as $50,000,000, about half of the estimated value of the entire stand.
