extent, but at least in one place. If a scion is to 

 be grafted on a branch of its own size, or not very 

 much larger, each is cut across obliquely, and each 

 is slit or notched, so that when pressed together 

 they interlock, the scion thus being held pretty 

 firmly. Such a graft is called a "whip" graft or 

 "splice" graft. 



A scion may be engrafted on the trunk of a 

 sapling by bending the sapling and making an 

 oblique incision with a knife, into which the 

 wedge-shaped scion is inserted, care being taken, 

 of course, that the living tissues come in contact. 

 This is called a "side" graft. The same method 

 may be employed to graft a scion on the root of 

 a tree. 



Where the graft is planted on a larger limb, 

 the method of "cleft" grafting is employed. This 

 consists of sawing off the branch of the stock, 

 and splitting it with a knife or wedge at the end. 

 The base of the scion is cut into a wedge shape, 

 and this is thrust into the cleft in such a way 

 that the inner bark of the scion comes in con- 

 tact with that of the stock. A scion may be in- 

 serted on either side of the stock, or in the case 

 of a large branch four or more scions may be 

 placed on the same branch. 



The process of grafting is completed by cover- 

 ing the exposed surfaces with grafting-wax, and 

 wrapping a cloth about the branch for further 

 protection during the time of healing. Mr. Bur- 

 bank's formula for grafting- wax is as follows: 



"Eight pounds of resin and one pound of bees-
