Mr. Meyer's report upon this disease, as he found it in China, has some points which may be of interest to you. He said the disease apparently had been there for many years, as the lesions of the disease showed if they were examined carefully. The fact that it has been there for many years is, I think, questioned by no one at the present time. Its growth in China seems to be somewhat different, in fact in many cases quite different, from the growth on the American and the European chestnut trees. It is rather of the type that we are familiar with on the resistant Japanese trees. More-over, it appears on some of the trees as shown in the photographs which I will pass around. The appearance of the disease more closely resembles, in some ways, what we are familiar with in the European apple canker as it appears on the apple trees. I think those who are familiar with the apple canker will notice the resemblance, in at least one or two of these photographs. Now, I don't mean by that that it is the same as the apple canker, but I do want to call your attention to its appearance in these photographs, and at the same time, to tell you something that Mr. Meyer wrote about this disease as it appeared in China. He said he found no trees that were absolutely killed by the disease. This may mean, and probably does, that the Chinese tree is resistant, to a certain extent, to this disease; that is, it shows a certain amount of resistance, much in the same way that the Japanese chestnut tree does to the disease in this country. For some years (as some of you will remember, I think) there have been two different views as to the origin of this disease. One is that it is a native fungus which, for some reason, has assumed a parasitic form; the other that it is an imported disease. The principal reasons for the latter view are that it spreads in this country on the American chestnut in much the same manner that other imported diseases have spread on other plants. The fact is that this disease (so far as we can find absolutely identical with the American form) has been found in China; about this point there is no doubt at all, and I think we can safely say, although we cannot absolutely prove it at this time, that the disease in this country was imported from the Orient. What bearing this will have on the question of control of the disease in this country remains to be seen.
