bore crops, without any sign of blight until the
terrible drought year of 1930 when some of them developed blight and
then later recovered from it. I think mollissima chestnuts are less
likely to die than cherries or peaches, and probably less likely than
apples.

While the subject of blight resistance in chestnuts is up, I should like
to call attention to the fact that there are many Japanese chestnuts in
the eastern part of the United States that have survived the blight.
Some of them bear good nuts, very good nuts, although most of the
Japanese have a properly bad reputation for flavor. Doubtless an
experimenter has a chance of producing something very valuable by
breeding from the best blight resistant Japanese chestnuts now surviving
in the eastern United States.

Green Shoot Grafting of Trees

_By_ ROBERT T. MORRIS, _M. D. New York_

In the course of experimental work with trees I grafted scions of
several species and varieties into stocks of their respective genera at
times of the year when grafting is not commonly done.

Scions were taken directly from one tree and placed at once in another
tree. To this method I gave the name of "immediate grafting" in order to
distinguish it from grafting with stored scions which might be called
"mediate grafting" indicating the intermediate step of storage.
Immediate grafting was successful in mid-winter in Connecticut but I had
no thought of making it a practical feature of our work beyond the
recording of a research fact.

Immediate grafting was successful in mid-summer in Connecticut. The
procedure was very different from that of winter grafting. In summer the
new green growth of the year was cut away completely from a scion and
the remaining wood of one or more previous year's growth was depended
upon for sending out shoots from latent buds. That is what happens after
accidents to limbs or to trunks of trees and it occurred in the same way
with my scions. Furthermore, it seemed to offer new hope for the
propagation of walnuts, maples, and grapes, for example, because the
free flowing sap of such species in the spring and early summer has led
to attacks upon the sap by bacteria and fungi which ruin repair cells.

I have already published elsewhere the statement that immediate grafting
may be done in the way described in any month of the year with many
kinds of plants. Exceptions to this rule will doubtless appear here and
there. For example, the grafting o
