ut culture to obtain these papers, since some of the
insects treated are quite general feeders and may be expected to occur
on most all varieties of nuts.

The secretary also has asked that reference be made to the hickory bark
beetle. This is essentially a forest insect and has been treated by
Doctor Hopkins in Circular 144 of the Bureau of Entomology.

Attention should be called to an insect rather recently introduced into
the New England States, which will probably attack nut crops, namely,
the so-called leopard moth, already indicated in the list of titles on
nut insects. This pest will prove a difficult one to control, as it
infests the trunk and larger limbs.

The whole question of the control of nut insects is complicated by the
often enormous size of the trees, so that operations, effective in the
control of insects, say affecting the apple, are not entirely practical.
It is a point to be determined whether it will be profitable to spray
large nut trees, such as the pecan. In some instances we believe that it
will be, and the Bureau of Entomology now has in Florida one of the
large power spraying outfits, formerly in use in the gipsy moth
spraying, to determine the cost and benefits of such work.

In concluding these brief remarks I wish again to reiterate my pleasure
in having the opportunity of appearing before you, and to assure you of
the interest of the Department in the insect problems confronting nut
growers. Nut culture is bound to increase enormously and insect injuries
will probably correspondingly increase. I believe, however, that these
injuries will be found controllable, as has been determined to be true
in the case of practically all important native or introduced crops.

THE CHAIRMAN: We are glad that Professor Quaintance has told us about
the different bulletins. The secretary will have a list of these. I am
now going to call for Mr. Rhodes, who is an expert propagator of Persian
walnuts, and he is going to give a demonstration on methods of
propagating the walnut.

MR. RHODES: I am employed over at Arlington and I have been helping
Professor Lake in his work there at the farm. Last year about the 15th
of July we put in about seventy-five grafts using the cleft graft, and
the side graft, and at the same time we put in some chip buds. Professor
Lake has a little instrument which is known as a chip budder. We used an
ordinary bandage, such as surgeo
