On both stock and scion a cleft is made which serves to separate a 

 small tongue of wood. This cleft is made in exactly similar manner on 

 both stock and scion; it commences at about the upper third of the 

 bevel (towards the point), and extends, following the fibres of the wood, 

 to the lower tliird. This will be readily understood from Fig. 6. In 

 order to bring about the complete fit here sliown, it is necessary to bind 

 the graft. Witliout it there is ajit to be a gap between the points of 

 stock and scion and the cut surfaces on which they are to lie, whicli 

 may result in these points drying out; the longer the bevel, the greater 

 the danger of this occurring.

The tongue is fornietl by a cleft, following the grain of the wood, commencing 

 at the upper third of the stock and penetrating to the lower third. The scion is 

 prepared in an cxacth' similar manner.

Most French authors recommend cutting the cleft with the grain of 

 the wood. Bioletti, however, recommends an oblique cut — 



The tongues are made with a slow, sliding motion of the knife. They are 

 commenced slightly aliove one-third of the distance from the sharp end of the 

 bovcl. and cut down until the tongue is just a trifle more than one-third the 

 length of the cut surface. The tongue should be cut, not split. The knife
