GRAFTING BY DETAC1IED SCIONS.

num. of the stock. As in this case both edges of the alburnum of the scion 

 come in close contact with the alburnum of the stock, the chances of success, 

 other circumstances being alike, are increased. Incases of this kind also, a longi- 

 tudinal notch is sometimes cut out, instead of a slit, and the scion cut to corre- 

 spond. Sometimes also the scion is prepared with a shoulder, more especially 

 when it consists of two-years old wood, and this mode is called shoulder-grafting. 

 654. Cleft-grafting the vine is shown in fig. 205, in which a is a bud on 

 the scion, and b one on the stock, both in the most favourable 

 positions for success. The graft is tied and clayed in the usual 

 manner, excepting that only a small hole is left in the clay 

 opposite the eye of the scion, for its developement. In graft- 

 ing the vine in this manner, when the bud b on the stock is 

 developed, it is allowed to grow for ten or fourteen days, 

 after which it is cut off; leaving only one bud and one leaf 

 near its base to draw up sap to the scion till it be fairly united 

 to the stock. The time of grafting is when the stock is about 

 to break into leaf, or when they have made shoots with four 

 or five leaves. By this time the sap has begun to flow freely,

 grafting the vine, though if vines are in good health and their wood thoroughly 

 ripened, all the bleeding that usually takes place does little injury. In 

 Flanders the rose is frequently grafted in the cleft manner, the scion, if 

 possible, being of the same diameter as the 

 stock (fig. 206, a) ; or the cleft in the stock is 

 made so near one side of the cross section as 

 that the bark of the wedge part of the scion 

 may fit the bark of the stock on both sides- 

 (b). Sometimes a shoulder is made to the 

 scion (c), in order that it may rest with greater 

 firmness on the stock ; and the wedge part of 

 the scion, instead of being part of an internode, 

 as at d, is, when practicable, selected with a bud 

 on it, as at e. The camellia is sometimes cleft- 

 grafted, with only a single bud on the scion (fig. 

 207, a), which is inserted in the stock &, just 

 when the sap is beginning to rise, and being tied, 

 it is found to take freely without claying. Epiphyllum truncatum is fre- 

 quently cleft-grafted on Pereskia aculeata, as shown in fig. 208. 



655. Saddle-grafting (fig. 209) is 

 only applicable to stocks of moderate 

 size, but it is well adapted for standard 

 fruit-trees. The top of the stock is 

 cut into a wedge shape, and the scion 

 is split up the middle, and placed 

 astride on it, the inner barks being 

 made to join on one side of the stock 

 as in cleft-grafting. The tying, clay- 

 ing, &c., are of course performed 



the usual manner. Fisr. 210 represents
