Several of them are applicable to the com-mon methods of culture and are generally serviceable; some, on theother hand, are useful only in certain cases; none are there which arenot more or less practicable and useful. 32.—ARCH OR REVERSE GRAFT. This resembles graft by approach No. 1, except that in place ofgiving the graft a double curve in the form of an S, and thereby pro-ducing a parallelism in the two parts, a curve of the graft is broughtfrom above into union with the subject, to which it is to be attached,into which latter it is inserted in a manner somewhat similar to thatadopted in the cleft graft. (Fig. 42.). The system used for uniting the parts may be that by lateral incis-ion, as seen in the figure, or by simple or double cleft. This graft isused at the present day in some places, and recommended even byofficial documents, from which Figure 42 is copied. It depends onthe principle that the sap circulates indifferently in either subject, in which the sap circulates differently from that in thegraft, becomes readily united to it and continues to nourish it, when,after the union is formed, the graft is separated from the mothervine. 33.—CROWN GRAFT. Instead of splitting the vine to receive the graft, the latter isinserted between the bark and the wood, first being trimmed downto a long slender point, pared off on a single side only, which is madeto slide smoothly along the wood beneath the bark. This system is GRAFTING THE VINE. 37 one of the best, and is especially useful for aerial woody grafting oftrees ^vith regular and flexible bark. But it is difficult and uncer-tain
