angles, so that the bark at the outer edge of the cion 

 will be in contact with the bark of the stock ; if the 

 stock is large, cions may be inserted upon both edges 

 (Fig. 102). 



For greenhouse work, the method known as side 

 grafting (Fig. 103) is especially valuable. The stock is 

 prepared by making a slanting downward cut about an 

 inch long in the side of the stock ; it should penetrate 

 far enough towards the lower end to separate the cam- 

 bium layer of wood. The cion should be cut about the 



same as for a cleft 

 graft, except that 

 the wedge should be 

 about one-half lon- 

 ger on the inner 

 side than on the 

 outer. When pushed 

 into place the tongue 

 on the stock should 

 cover the end of the 

 cion and hold it in 

 place. A modified 

 iorm of this method 

 of side grafting is 

 known as veneer 

 grafting, and while 

 it is perhaps more likely to give a perfect union, it neces- 

 sitates holding the cion in place while tying it. The 

 cuts upon the stock are made just as in ordinary whip 

 grafting, but the tongue is cut with a slanting stroke, 

 so that it is only about one-fourth of an inch, or slightly 

 less, in length. The lower end of the cion is cut off at 

 an angle of 45 degrees, and the bark and a little of the 

 cambium are removed for about one inch at the end of 

 the longer side of the cion. The cion is then placed 

 against the stock so that the tongue upon the stock will
