ASEXUAL PROPAGATION ON ROOTS OF OTHER PLANTS 79 



slanting cut is then made in the stock and cion, as shown in 

 Fig. 52, and the two parts are forced together as illustrated. 

 If the graft is made properly, no light should show through. 

 The tongues should not pro- 

 ject but should come to the 

 position shown in the illus- 

 tration. If they project, 

 they may be cut off to the 

 proper length. The grafts 

 are wound with a few turns 

 of waxed knitting cotton 

 which breaks easily, so as 

 not to cause girdling when 

 growth takes place. In com- 

 mercial establishments, the ^ 

 grafts are wound by a ma- FIG 

 chine. Many propagators 

 do not wind the grafts at 

 all, but fit them firmly together. If whip-grafts are made 

 on parts above ground, the grafts must be waxed at all 

 cut surfaces. 



129. Cleft-graft (Figs. 53-57). This is one of the oldest 



grafts. It is used for the 

 most part on branches 

 three-fourths of an inch 

 in diameter or larger. 

 The branch to be grafted 

 is first sawed off. The 

 stub is then split with 

 a grafting tool and a 

 wedge put in to keep the 

 cleft open. The cion is 

 cut obliquely on both sides as shown in Fig. 55, a bud 

 being left low down on the cion just above the place where 

 the cut surfaces begin. The wedge of the cion is left a little
