GRAFTING.

Grafting.—Whip or tongue grafting (Fig. 18) is the mode most in use in the best fruit-tree nurseries, and is so called from the manner of cutting both the stock and scion in a sloping direction, on one of their sides, so that when brought together they fit exactly, and thus may be tied together. In former times this species of grafting was performed without a slit or tongue, and in that case the former term was more applicable. Subsequently the slit or tongue has been added, which has given rise to the latter term. “The scion (or shoot, a) and stock (or tree, b) being cut off obliquely, at corresponding angles as near as the operator can judge, make a slit nearly in the centre of the sloping face of the stock downwards, and a corresponding tongue in the scion upwards—this is called tongueing; the tongue, or wedge-like process, forming the upper part of the sloping face of the scion, is then inserted downwards in the cleft of the stock, the inner barks of both being brought closely to unite on one side, so as not to be displaced by tying, which ought to be done immediately with strong cotton twist, tape, or any thready material, brought in a neat manner several times round the stalk. The next operation is to clay the whole over, an inch thick on every side, from about half an inch below the bottom of the graft to as much over the top of the stock, finishing the whole in a long, oval form, and closing it effectually in every part to exclude air and water, which is the sole object of claying. Grafting Clay is very simply made of any heavy loam procured from a depth of the soil that has not been subject to culture, combined with a fourth of droppings from the horse or cow stable, moistened and well beat together with a stick, till perfectly incorporated and tough, allowed to stand for a few days, and then softened for use. These materials are always at command; there are several kinds of grafting wax, but they are not so easily prepared, and of no more utility than the elay. Grafting can be performed close to the ground, and earth drawn up round the junction, which will be as serviceable as clay.

Cleft Grafting (Fig. 19) is another method of operating upon large trees, or stocks, where the bark or rind is not too thick. The head of the stock, or branch, being cut off smoothly, a slit is made in the top of the stock with a strong knife or chisel, deep enough to receive the scion, which should be cut sloping, like a wedge, so as to fit the slit made in the stock. The wedge side, which is to be placed outward, is to be made thicker than the other; and in placing the scion into the slit, it must be so adjusted that the rind or inner bark of the scion joins that of the stock; for if these do not unite, the grafts will not succeed. When the stocks are large, two grafts may be put in, (as represented in the figure,) which tie firmly and clay over, as directed for Whip Grafting. As there will be a greater body of clay, in this case, it will be more liable to fall off; it will therefore be necessary to wrap moss, soft hay, or pieces of cloth round the balls, to prevent the rain destroying them. There are many other methods of grafting, all on the same principle differently applied. Some of our amateur correspondents, particularly John A. Crawford, Esq., of Columbia, S. C., takes large limbs two or three inches in diameter, and five to ten feet long, and grafts them into other stocks. These limbs produce fruit the same season. Root grafting is also practised to a considerable extent. Trees and stocks for grafting upon should always be fully established before being operated upon, having had at least one season's growth. Farmers may graft in every field and hedge-row, and by every fence-rail. Fruit trees require no more room than the cumberers of the ground in the shape of saplings, briars, and thorns. Fruits make an ample return, while the latter requires food for which they do not pay. There is no garden or farm but should have a few reserve Plum, Pear, Apple, Peach, Cherry and Quince stocks, on which they can place any sort of fruit they wish to preserve and multiply. These can be readily procured by sowing a few seeds, or planting a few pits, every year. Stone fruit, such as the Cherry, Peach and Plum, do best by budding. Apples and Pears do well by both grafting and budding. Budding is performed as follows:
