having two or three buds. The lower end of the scion 

 must be wedge-shaped, with the outer edge thicker. 

 This last is important, because if the inner edge were 

 thicker, the outer edge, where the living cambium is, 

 would not touch the cambium layer of the stock, and the 

 scion would die. It must be remembered that these 

 two living layers must be in close contact or no union 

 will take place. 



All cut surfaces should be covered with grafting wax, 

 which is made as follows : Melt and pour into water 

 four parts of resin, two of beeswax, and one of tallow; 



as the mixture 

 cools, work it with 

 the hands until it 

 is of a yellowish 

 color. Make it into 

 rolls and wrap them 

 with waxed paper 

 to prevent them 

 from sticking to-

Whip Grafting. - 



This method is 

 much used in graft- 

 ing on stems when 

 the scion and stock 

 are about the same 

 size. In this case 

 both are cut with 

 a slanting surface, 

 from three quarters 

 of an inch to an inch long. The stock has a slit, or 

 tongue, made in it down lengthwise from the cut, and
