Whip-Grafting. This method may be used on small 



stocks, three-quarters of an inch or 



less in diameter. It is best that the 



stock and cion be of the same size, 



but if such is not the case, the stock 



should always be the larger. A slop- 

 ing cut, an inch and a half long is 



made diagonally across the stock 



(fig. 50). A corresponding cut is 



made on the cion (fig. 50) and a 



tongue of wood is raised about the 



center of each cut with the knife held 



almost parallel to the sides of the 



wood. The tongue is raised a little 



on both stock and cion and the two 



are gently but firmly shoved to- 

 gether (fig. 50). Then the point of union is securely 



bound with a strip of waxed 

 cloth. The after-treatment is 

 the same as for cleft-grafting. 

 Crown-Grafting. This 

 method is one of the 

 best for working trees which 

 have been frozen back or for 

 working large trunks at the 

 ground. The trunk is cut 

 squarely off at or somewhat 

 below the ground and the cut 

 surface is made smooth with 

 a knife. If the outline of the
