GRAFTING.

used for young plants ; 3rd, an iron chisel, described here- 

 after ; 4th, a hammer, or rather a small mattock, which is 

 used for driving the chisel and to clear the soil away from 

 the plant (Fig. 80) ; 5th, a strong grafting knife, used for 

 smoothing the sections and to prepare the scions. 



All these tools are known, and the illustrations are sufrr* 

 cient to give an idea of them ; however, attention is drawn 

 to the grafting chisel, which must be made so as to perform 

 several operations. As a matter of fact, the grafting chisel 

 may be simply considered as a wedge used to split a piece 

 of wood, and if necessary the ordinary cold chisel could be 

 used. But, as we have already seen, in the case of a single

scion baing grafted on a stump, the cleft is only made on 

 one side, so as to preserve the stock and allow the side of 

 the cleft to press against the scion. For this purpose the 

 blade of the chisel should not be of the same thickness on 

 both sides ; sometimes it is the shape of a knife having one 

 side sharpened to allow of a cleft being made on the young 

 stumps (Fig. 81). 



(b) Tools used for Cleft-grafting Young Plants. In this 

 case a cleft is made with a strong grafting knife. However, 

 Corny, of Garons, has invented an arrangement greatly 

 facilitating the execution of this operation, and allowing it 

 to be made with great perfection. Comy's arrangement 

 comprises : 1st, A gauge ; 2nd, a scion box; 3rd, a graft- 

 ing knife for the scions ; 4th, a stronger grafting knife for 

 the stocks.
