agnum will absorb a good deal of
moisture without actually becoming wet and will also hold this moisture
and give it off more slowly than any other packing material with which I
am familiar. This is especially important in keeping scions of nut trees
in good condition for grafting, because, if packed too damp, the scions
are soon spoiled for grafting, even if kept at a low temperature.
As a precaution against fungi, we usually use bordeaux mixture, two
thirds standard strength, to dampen moss for packing scions, especially
if they are to remain in storage several months.
Our rule is to use moss only slightly damp to the touch and if used in
sufficient quantity, say two or three times as much bulk as we have of
scions, we find no trouble in keeping scions in perfect condition for
months. In fact, as an experiment, we have carried pecan scions in cold
storage and without re-packing for fifteen months and then get a fair
stand of grafts to grow.
We usually advise putting scions in cold storage where convenient,
especially if they are for use in late May or June, but this is not at
all necessary if the scions are packed in moss only slightly damp. In
fact scions kept in an ordinary cellar at a temperature around 50
degrees have given us better results on the average the past two years
than have those from cold storage.

AFTERNOON SESSION, FRIDAY, OCTOBER 8, 1920, 2 P. M.
THE PRESIDENT: We very fortunately have with us a gentleman from the
Bureau of Entomology, Mr. F. E. Brooks, who will talk to us about nut
insects for a time and we will be very glad to listen to him.
MR. BROOKS: I believe your program is full for this afternoon and I
shall keep you but a few minutes.
A little more than a year ago the problem of insects affecting the nut
crop of Northern United States was assigned to me by the Bureau of
Entomology. I wish to say the work has been very delightful to me from
several standpoints. In the first place, it has brought me into
association with a delightful group of workers. I want to express to you
the pleasure I have had in meeting the various nut growers of the
northern part of this country and noting the hearty way in which they
are ready to co-operate in solving the nut insect problems. The field of
work is interesting because there appear to be in sight no insect pests
that promise to embarrass or overwhe
