Veneer Grafting of Herbaceous Plants. Secure healthy specimens of Lycopersicum about 2 5 cm. in height, or larger, So- larium tuberosum of the same size and a number of geraniums. Make the following grafts: cut a tangental slice from the surface of a part of the stem of the tomato firm enough not to • be easily crushed, in such manner that the ring of woody tissue is cut into. Now select a geranium stem of the same size and cut off a section of the stem a few cm. long from which the leaves have been removed with the possible exception of one or part of one. Make a tangental slice on one side of this cutting deep enough so that the wood of the scion and stock, as well as the cambium of both, will be in contact when the scion is applied to the stock. Tie the scion in position with the tissues firmly pressed together by means of soft cords, or raffia fiber. It may also be of advantage to bandage with wet moss or cover the union with a layer of soft wax made of beeswax, resin and lard to prevent desiccation. Cut away the stock above graft and set the prepara- tion in a cool house for about ten days, then bring into a temper- ate house. Care must be taken not to disturb the scion during the process of union, and to remove all leaves and branches of he stock below the graft. Repeat the process, putting scions of tomato on potato and scions of potato on tomato. The greenhouse stock will offer many other examples of suitable material for such experimentation. 1 Bailey, L.
