Another way is to put your pollen in cold storage with some sphagnum moss, just put a little damp moss in your box with the pollen and put it in cold storage, and keep it at just about forty, above the freezing point. Another way is to put branches with dormant flower buds in cold storage. Hazels, for instance, may be kept for six months in this way. Put them in water, in the sun, and you soon have flowers furnishing pollen. I would take up the whole session of two days here if you were to ask too many questions along that line. (Laughter.)
Mr. Littlepage's question about the weevils. The question may be settled very easily where there are not many chinquapin trees. That is the case in Connecticut. Collect all the nuts, and you collect all of the weevil larvae. Curiously enough, the common chestnut weevil, that had become very abundant, has disappeared locally with the disappearance of our American chestnut, and has not attacked our chinquapins. If you have an orchard of chinquapins and collect all the nuts you will soon dispose of the weevils. That is the only way that I know of for disposing of the weevils. Eat them up. (Laughter.) You can pick out the weevil chestnuts fairly well if you toss all of the nuts into a cup of water and pick out the ones that float. Pound them up with a mallet and throw them into the chicken coop.
Dr. Smith asks if the use of the tree chinquapin as a stock for the American chestnut would give good-sized trees. Undoubtedly, and, besides that, if it is used for hybridizing purposes, we shall probably find that we have, now and then, an individual that is very much larger than the American chestnut or the tree chinquapin. It is a peculiarity of hybrids to show eccentricities, and many hybrids that occur are very thrifty and larger than either parent. That is the case with the Royal walnut that they have said so much about in California. It grows so rapidly there that even Californians do not dare to tell about it. (Laughter.)
Another question, the last one—will the effect of using a bush chinquapin stock for the American chestnut be like that of growing sour cherries upon stocks which do not carry them well? Now, we have there what the lawyers call "a question of fact," and we shall have to work that out. Some tops will exhaust a root. Some tops will grab a root by the back of the neck and drag it right along. Some tops will adjust themselves philosophically to almost any sort of unusual conditions, and go on and bear fruit like true philosophers. We have an instance of that in the dwarf apple, which is a success. We have an instance of failure in some of the cherries which exhaust themselves. We have an example of dragging the smaller stock along when we graft the Royal walnut upon the common black walnut. The Royal walnut just drags the black walnut along where it doesn't want to go at all. So there we have three instances of grafting a foreign visitor upon another stock.
I have taken more than my share of time, Mr. Chairman, but the discussion has been very interesting, indeed. (Applause.)
THE PRESIDENT: I am going to take the liberty of asking Dr. Morris one more question, which, perhaps, is of interest to others. In your experience with the golden-leafed chinquapins, from how far South have you secured stock, and how far North will the golden-leafed chinquapin grow?
DR. MORRIS: My specimens I got from a dealer in Portland, Oregon, and they grew pretty far North. The tree ranges from Oregon and Washington down through the lower extremities of the Coast range, but we had better get the northern forms, and there is one man, Carl Purdy, of Ukiah, California, who has the golden chinquapin for sale.
THE PRESIDENT: The next subject on the programme is the American black walnut. We have sent to the membership a series of questions about the black walnut which I will read for the benefit of those who haven't this programme.
First. What evidence is there to show that the black walnut may become a valuable nut commercially?
Second. Is quality important with the black walnut, and is there much difference in the quality of different nuts?
