the extreme limit of the
blossoming range of the species, who will send pollen. For instance,
Professor Hume, in Florida, sends me chestnut pollen in time to cross my
oaks, and Professor Conser, of the University of Maine, has some beeches
that blossom in time for me to cross with chinquapins and oak trees.
That is one way to do it.

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
