blight. Mr. Corning writes: “Of my Japanese trees a great 
many will have to be cut down. At the same ratio of progress, 
none will be left in three years.” And in another letter he 
states further, in answer to our inquiry: “I bought in New 
Jersey cions for four kinds, namely, Japanese, Numbo, Ridgely 
and Paragon, all on chestnut sprouts. I bought at the same time 
trees from seedlings, but they all died before the blight struck 
us. I find the Japanese stand so far the best. The Paragon 
are the poorest, although they have made the best growth and 
produced the most chestnuts. I find the infection commences 
about at the juncture of the grafts on the sprouts, and runs 
up and down, faster up than down.” 
Dr. Robert T. Morris, of Stamford, has experimented more 
with different varieties than anyone else in the state, so his 
statement, following a discussion of a paper by Collins (13, 
p. 43), is of special interest: “In my own orchards I have 
twenty-six kinds of chestnuts, and have followed them along 
for the purpose of determining which ones would resist the 
blight best. I cut out last year [1910] five thousand old 
American chestnut trees on my property. There is not a tree 
in all that part of Connecticut, the vicinity of Stamford, that 
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 Coreans 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 chestnuts, because these Coreans resisted 
the blight. But when I grafted them on the sprouts of American 
stumps, at least 50 per cent. of the Coreans blighted, showing 
that the pabulum wanted by the Diaporthe seemed to be fur- 
nished by the American chestnut. I had some chestnuts from 
North Japan that resisted the blight, and yet these grafted on 
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
