one black walnut.

Prof. Slate: I do not think there is more than one kind.

Mr. Stoke: It is interesting to know that while the black walnut has
been higher in price than the English walnut, so that manufacturers have
been substituting the English walnut for the black walnut, this year the
black walnut has dropped as much as 10c per pound under the English and
is now about 5c, I believe. Consequently the black walnut has come into
its own and is now being substituted for the English walnut.

Mr. Frey: I would like to mention alternate years in bearing. If apple
trees can be made to give a fair crop each year by good care, feeding
and spraying, it is my thought that walnut trees will do the same thing
under the same conditions. But we must remember that forming the hard
shell is a most difficult thing for a tree to do.

Prof. Neilson: I should like to draw your attention to a drawing sent me
by J. U. Gellatly. (The paper was held up for all to see.) Just look at
the size of the leaves. That is a tracing of the leaf of a hybrid
English walnut and heartnut. He sent it along as evidence of its vigor
of growth. This large compound hybrid leaf measured 27 inches from tip
of the leaf to the bottom of the last leaflet, exclusive of the stem
which was 5 inches long. Many of the larger leaflets measured 5 x 9
inches, shape, oblong ovate, edges of leaf, serrate, total width of
compound leaf, 17 inches.

Dr. Smith: I should like to suggest to Mr. Frey that the theory he
suggested might be supported if the tree were placed in a particularly
favorable location.

Mr. Hershey: I should like to remind the audience of Judge Potter who
told me some years ago that on his farm in Southern Illinois he got
three doubles of his meadow grove of about 50 hickory trees, by using
plenty of good horse manure, phosphoric acid, and potash. The increases
were that he doubled the amount of growth and the size of the nut and
changed the trees from alternate bearing to yearly bearing.

Black Walnut Notes for 1933

A number of developments in connection with the black walnut industry of
the East have taken place during the last 12 months which appear to be
of such importance as to justify special record at this time. Some of
these have to do with the production and marketing of and prices
received for, the wild product
