This method served a purpose in advancing our knowledge of the subject, but not enough grafts caught to encourage me greatly. Following out the same line of thought, I began this year by making union between stock and scion according to inarch principles. The scion instead of remaining attached to its parent plant, according to former inarching method, had been transferred to the stock, leaving two or three inches of scion free below the point of grafting, as illustrated in the drawing. The proximal part of the scion was then inserted into a test tube containing water. In this case, as with placing the test tube at the top of the scion, difficulty was found in preventing the growth of microoerganisms in the water. The addition of benzoate of soda, borax, boracic acid, and sulphate of copper, while preventing the development of microoerganisms, seemed also to be objectionable to the physiologic processes of the plant. It occurred to me that the principle of the balanced aquarium might be applied, and acting upon this idea specimens of a pond weed (Utricularia) were introduced into the test tubes. This seemed to settle the water question completely, but it was well along in the summer before I made grafts and applied this principle. From one to four leaves, or parts of leaves, were left upon grafts which were applied to stocks according to this new inarching method. All of these leaves remained green until autumn, and fell with other autumn leaves of the stock. Two specimens which I have cut away for examination seemed to show a very good union between stock and scion. I am presenting a description of the new inarching method promptly, before obtaining more extensive statistics, in order that members of this society may apply it experimentally next spring. Should it succeed according to present promise, it will allow nurserymen at least two months of grafting season, and they will not have to rush their work. In addition it will perhaps open up a method of grafting which may be employed freely with nut trees in the northern states. Another unusual method for propagating nut trees consists in facilitating the development of adventitious buds from the roots of some particularly desirable tree. I do not know at the present time how many species of nut trees will develop adventitious root buds, as my experiments have been confined to roots of the shagbark hickory, beech, and hazel. Segments of roots of these three species when placed in sand, allowing an inch or so to protrude, will develop adventitious buds if they are kept warm and moist. Various lengths of root segments have been employed, ranging from two or three inches up to two or three feet. The beech and hazel will apparently start adventitious buds from almost any sort of root segment; but in the shagbark hickory, adventitious buds started best upon root segments which were more than six inches in length and more than half an inch in diameter.
