er of leaves. For budding you
transfer immediately. In fact, budding technically comes under the same
physiologic principles as grafting. In budding I do that work in my
place at Stamford, Conn., about the latter part of July or early August.

DR. KELLOGG: Do you use the same method in transferring buds?

DR. MORRIS: Yes, I fix them the same way as I do the graft and
cover everything with paraffin. I have even had a little short side
graft grow using this paraffin method, a graft two or three inches long.

DR. KELLOGG: Tell us about those fatherless walnuts.

DR. MORRIS: In the course of crossing the nut trees, we
supposed, as a matter of course, that we must always have the pollen
from one tree, or from a tree which bore the staminate or fertilizing
flowers, in order to develop nuts or fruit of any sort; but on one
occasion I covered a lot of Chinkapin female flowers with paper bags; I
didn't have pollen enough to go around and left the bags on because I
happened to be too lazy or too busy to pull them off. About a month
later when I did take them off I found a full set of chinkapin nuts
under those bags. They had received no pollen. That was an observation
of a good deal of interest. It may have been that they had gone on by
what we call parthenogenesis, and we had the children without the
father, had the female parent only, the fatherless chinkapin. It sounds
sad. I followed up the experiment with other nut trees, and found that
not infrequently we may develop fatherless nuts. The effect will be,
according to natural law, to intensify the characteristics of one
parent. The female which bears this fruit, this child, without a father,
will give to that child an intensification of her own characteristics.
That will be the effect of parthenogenesis. That may be continued
through several generations perhaps; we do not know. It is new, quite
new. (Applause).

THE NUTRITIVE VALUE OF NUTS

F. A. CAJORIE, YALE UNIVERSITY, NEW HAVEN, CONN.

Mr. President and members of the Northern Nut Growers' Association: It
was with great pleasure that I accepted the invitation of your
Association to be present at this convention and give a discussion of
nuts and nut production, from the point of view of their nutritive or
food value. During the last few years our knowledge of nutrition and the
parts that individual foods may p
