A CLEFT GRAFT. 



This reproduction of a color-photograph illustrates one of several 

 common methods of grafting, as practiced in Mr. Burbank's orchard. 

 The engrafted twigs are called "Scions," the branch on which they 

 are placed is called the "Stock." The essential principle is that the 

 inner bark, called the Cambium layer, of the scion, should be brought 

 into intimate contact with the corresponding layer of bark of the 

 stock. The work is completed by covering stock and scion with 

 grafting wax, and wrapping cloth about the stock for further pro- 

 tection.
