_Grafting_ differs from budding, in the scion consisting of several buds instead of one. It is also performed at a different time of the year; as March and April are the proper seasons for grafting, whereas budding is never performed till after Midsummer. In grafting, sometimes the head of the stock is cut off, and sometimes only the branch, and the scion is selected according to the size of the part to which it is to be attached. When the scion and the stock have been both chosen, they are cut slantingly, so that one may fit into the other; and care being taken that the bark and soft wood of the two unite, at least on one side, the two pieces are bound together, and the ligature is covered with what is called grafting clay, that is, a mixture of stiff clay, with a fourth part of fresh horse-dung, and a small quantity of cut hay. Another kind of grafting clay is composed of equal parts of stiff clay and cow-dung. It is of very little consequence whether the scion and the stock are of the same diameter, provided they are so cut and fitted, as to leave no vacuity between them, in those parts where the union is to be effected; and, to keep them quite closely attached to each other, it is customary to form a tongue, or little projecting part, by making a slanting cut in the scion, and to make a corresponding slit in the stock to receive it. There are several kinds of grafting; but that which I have described, and which is called whip or tongue grafting, is the most common, and it is always performed with the firm or ripened wood. There is, however, another kind of grafting, now becoming common in the nurseries, which is performed with the young, or unripened wood, and this is called _herbaceous grafting_, because the parts of the stem with which it is performed are as succulent as the stems of herbaceous plants. In this kind of grafting, the shoot of the stock is broken off about two inches below the point, and all the leaves are taken off except two, one on each side, which are left to draw up the sap. The stock is then split with a very sharp knife between the leaves left on it; and, the base of the scion having been cut into a wedge-shape, it is fixed into the cleft made in the stock, which is bound tightly up with strips of cerecloth, or coarse cotton cloth covered with grafting wax, made of equal parts of turpentine, bees' wax and rosin, with a little tallow, melted together. Sometimes plants, especially camellias in pots, are grafted in this manner, and placed in a hothouse under hand-glasses, and the pot surrounded with moss, to keep the cutting as close as possible. This mode of grafting is of French origin, and it is called _la greffe etouffée_.
