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
