The cions must be thrust down, in the cleft, to the first bud, or even deeper, and it is im- perative that they fit tight. The line of sepa- ration between the bark and wood in the cion should meet as nearly as possible the similar line in the stock. The cions are usually set a trifle obliquely, the tops projecting outwards, to insure the contact or crossing of the cambium layers. Writers usually state that it is imper- ative to success to have the exact lines be- tween the bark and wood meet for at least the greater part of their length, but this is an er- ror. The callus or connecting tissue spreads beyond its former limits when the wounds begin to heal. The most essential points are/^^. Rooted rather to be sure that the cion fits tightly %]^/t''i^3t^i throughout its whole length, and to protect (xj^). the wound completely with an air-tight covering. The practice must be modified, of course, to suit the stock and the occasion. Sometimes rooted cuttings of grapes are cleft-grafted (Fig. 124), and these, being in the ground, are not waxed, and it is difficult to split the stub deep enough to allow the cion to be thrust in far. If the stub, in this case, has little elasticity after being split, it should be tightly wound to keep the cion in place. An old grape stock, cleft-grafted, and then covered with earth, is seen in Fig. 125. These covered grape stubs are usu- ally not waxed. This is the common, and generally the best, 'method of grafting the I2S- Cleft-grafting on old grape Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly re
