One point in regard to the chestnut weevil. When our chestnuts began to die here, I supposed that the chestnut weevils would immediately turn to my chinquapins for comfort. Weevils attack the chinquapins so extensively in the South that Mr. Littlepage said chinquapins would not be acceptable to Dr. Kellogg because they furnished so much animal diet. (Laughter). Curiously enough, the chestnut weevils did not go to my chinquapins. These chinquapins bear full crops, heavy crops, and one will almost never find a chestnut weevil in the nuts. I have found now and then a little weevil, about half a dozen altogether, that attacks the involucre at its point of attachment to the chinquapin. This looks like the chestnut weevil, but perhaps, only according to my eye, very much as all Chinamen look alike to one who has never seen them before. The matter of carbon disulphide for the painted hickory borer. I have used that apparently successfully, but I didn't tunnel through six feet of hickory tree afterward to see whether the borers were dead or not. It is a successful treatment for apple borers. I have no trouble with the apple borers now. I simply clean off the entrance of the hole, the "sawdust," and then with a little putty spread out with my hand make a sort of putty shelf below the hole, then I squirt in a few drops of carbon disulphide with a syringe, turn up the putty and leave it adhering to the bark, closing the hole. You can do that very quickly, and it spares a good deal of perspiring and backache. The black walnut. On one of my black walnut trees there is a serious pest, a very little worm which infests the involucre. The black walnuts of this tree fall early. I found that same worm last year also extending to the Asiatic walnuts, so that a great many Japanese walnuts fell early as the black walnuts fall, as a result of this little worm's working in large numbers within the involucre. I sent some specimens to New Haven for the species to be observed. This will be a very serious matter if it is going to involve the English walnuts as it does on Long Island. I have found the same thing, apparently, on Long Island in the black walnut, in the English walnut, and in the pecan. It causes a serious drop of these nuts at Dana's Island, near Glen Cove, Long Island. THE EXTENT OF THE HARDY NUT TREE NURSERY BUSINESS. R. T. OLCOTT, NEW YORK.
