PROPAGATION BT GRAFTING. 



207 



From the stock, d, d, d, d, the hark is removed to admit 

 the cion ; one to four cions, as shown, may he fitted to a 

 stock, and then all are held in place by a ligature of waxed 

 cloth, and the top of the stock also covered with wax. 

 This mode of grafting is usually considered best adapted 

 to large stocks, such as are not suitable for the ordinary 

 cleft grafting, but it may be used for stocks of quite small 

 size. The exposed wood of the upper end of the cion 

 should also be covered with wax, to prevent evaporation 

 of moisture therefrom, and with some kinds of trees.

such as the Hickories, Walnuts and Chestnuts, it is well 

 to cover or enclose the entire head of the stock and cions 

 with a hood made of oiled paper or thin muslin, until the 

 buds on the cions push into growth. This shading and 

 protection against drying winds, often secures the growth 

 of the cions when, if left exposed, they would fail. 



Triangular Ceown Grafting. — This is only an- 

 other form of the preceding mode, and one that should 

 have long ago taken the place of the more clumsy method 

 of cleft grafting. In this, the stock is not split, but in- 

 stead, a triangular incision is made in the side of the
