layer." The method by which cambium layers of stock 

 and scion are brought together is made clear in Figures 

 53, 54, and 55. 



The " tongue " or " whip " graft is very commonly The 

 used. Scion and stock must be of about equal size, 

 the diameter of a lead pencil being about right, and cuts 

 should be made as shown in Figure 53. In uniting the 

 scion and stock, care must be taken to have the growing 

 layers of the two stems in contact, at least on one side. 



In the " saddle graft " the stock is cut wedge-shaped ; The 

 the scion is split, placed over the stock, and firmly 

 pressed down. A saddle graft is easier to make than is 

 a tongue graft, but it has rather less cut surface where 

 growth may take place. (Exp. 8.)
