ons, and to report their results at later N.N.G.A. meetings. We do not expect these methods to work equally well in all parts of the United States and Canada represented here today, but they are giving promising results in the mid-South territory, and perhaps will have value in a wider area. As Mr. Davidson has so ably done at this meeting in the case of his Ohio plantings, we expect to give you a follow-up report on this work in west Tennessee at the Toronto meeting or later. "Twin-T" Budding in Chestnut Propagation Of the nut trees grown in this area, the chestnut has been the most difficult to propagate by budding. Nurseries in the upper South have propagated their pecan and walnut trees mostly by patch-budding or the similar ring-budding method, with very good success. When applied to chestnuts, patch-buds have seldom grown. The common T-bud, likewise, has been a general failure on chestnuts in America, though reported successful in Japan. Chip-buds have not been much-better. Several years ago, Dr. Max B. Hardy told me that the inlay bark-graft had been used successfully with Chinese chestnuts at the U.S.D.A, laboratory in Albany, Ga., following Dr. B. G. Sitton's use of this method with pecans in Louisiana. (It is described in a bulletin from Michigan State College, East Lansing, Mich.) I tried it in a small way, and had some success using it on chestnuts in July and August. This spring I suggested it to Mr. Roark and Dr. Richards, both of whom tried it out, using Castanea mollissima stocks and various scion varieties. Mr. Roark used the inlay bark-graft in the spring, topworking a C. mollissima seedling with scions of the Colossal, a hybrid variety from California. About 50 per cent of these have grown this year. Dr. Richards tried it during July, on C. mollissima seedlings from a different source. None of the Colossal would grow on his trees, but he was partially successful with scions of the C. mollissima varieties, Hobson, Carr and Zimmerman. He then devised a variation in the method which was highly successful with C. mollissima varieties. This I shall call the Richards "Twin-T" bud. In "Twin-T" budding, a vertical slit is made in the bark of the stock. Then horizontal cuts are made through the bark at both top and bottom of the vertical cut. The bud piece is cut from the well matured part of a current season's twig, leaving a rather thick slice of wood beneath the bud. (It may be as thick as half
