material was used on the orchard crops, and great growth response was
noted for the sprayed over unsprayed trees. As the home owner is forever
looking for new trees to plant, and trees with clean habits, the Persian
and particularly the Carpathian selections may be the answer.

The speaker exhibited photographs to illustrate his talk. They pictured
several of the different trees he had mentioned. The photographs showed
the conditions under which the trees grew, the effects of fertilizing,
and the injuries resulting from the winter cold. The reading of the
paper was followed by a short discussion, after which Dr. Rohrbacher
called upon Mr. Ira Kyhl, of Sabula, Iowa, who talked on the subject
"Nut Growing in Eastern Iowa."

Nut Growing in Eastern Iowa

IRA KYHL, _Sabula, Iowa_

About five years ago, I became very much interested in nut trees and
having hundreds of wild black walnuts and hickories I attempted to
graft, or rather top work, the black walnuts to Persian walnuts and
heartnuts, and the hickories to pecans and hicans.

My favorite, of course, is the Persian walnut, and in addition to top
working them on blacks I planted several grafted trees and several
hundred seed nuts. To my surprise and pleasure, nearly every seed grew
and the seedlings are still doing very well. I now have 35 to 40
varieties.

I have had very little winter injury, except with the Broadview variety.
The tops froze back a little and I had a little trouble with the bark
splitting on the larger trees. I covered the splits with tree wound
dressing and they are all doing well now. I consider the Schafer about
the best and most promising variety I have and the grafts take very
well. Most of the Carpathian varieties are also growing nicely and
especially the Illinois number 10,[4] which is a very rapid grower.

In top working, I use the bark slot method, usually setting two to three
grafts on a three inch stock, as at least one scion is almost sure to
start. These scions are fitted and nailed in place with a seven-eighth
or one inch nail and then well wrapped with one-inch industrial adhesive
tape. This seems to break or deteriorate with the growth of the graft.
I then thoroughly wax the taped part as well as all of the scion,
covering the buds rather lightly. After the scion has started to grow
well, a one by one strip is nailed to the stock. This extends from two
to three feet above t
