The Chairman: Please let me add that the hickory pumpkin idea is not to
be taken seriously. That is a highly speculative proposition. I have
found some times that, in a very scientific audience, men who were
trained in methods of science, had very little selvage of humor,--little
margin for any pleasantry, but this highly speculative suggestion,
curiously enough, is not in fact more speculative than would have been
the idea twelve years ago that you could hatch an egg, start an egg to
development--without fertilization.

Mr. Hutt: I would like to ask how widely you have been able to cross
species?

The Chairman: It has been possible to cross species of hazels freely
with the four species that I have used, the American hazel, Corylus
Americana; the beak hazel, Corylus rostrata; the Asiatic, Corylus
colurna, and Corylus pontica. These apparently cross readily back and
forth. With the hickories I think rather free hybridization occurs back
and forth among all, but particularly in relation to groups. The
open-bud hickories, comprising the pecan, the bitternut, the water
hickory, and the nutmeg hickory, apparently, from my experiments, cross
much more readily among each other than they cross with the scale-bud
hickories. The scale-bud hickories appear to cross much more freely
among each other than they cross with the open-bud hickories; not only
species but genera may be crossed, and I find that the walnuts
apparently cross freely with the open-bud hickories and the open-bud
hickories cross with the walnuts. I have thirty-two crosses between the
bitternut hickory and our common butternut, growing. All of the walnuts
apparently cross rather freely back and forth with each other. I have
not secured fertile nuts between the oaks and chestnuts, but I believe
that we may get fertile nuts eventually. The nuts fill well upon these
two trees fertilized with each others' pollen respectively, but I have
not as yet secured fertile ones. We shall find some fertile crosses I
think between oaks and chestnuts, when enough species have been tried.

Mr. Hutt: Do you notice any difference in the shapes of any of those
hybrids, the nuts, when you get them matured and harvested? Do they look
any different from the other nuts on the tree?

The Chairman: There isn't very much difference, but I seem to t
