84 PROPAGATION BY DIVISION. [CHAP. IV, 



kind of grafting is practised with trees and 

 shrubs, the head of the stock is cut off; but a 

 modification of it is practised with succulent 

 plants, in which the end of the graft, having 

 been cut into the shape of a wedge, is inserted 

 in a cleft or notch made in the side of the stock 

 to receive it, and the line of junction is covered 

 with grafting-wax. The tubers of strong com- 

 mon dahlias may be grafted in the cleft manner 

 with choice sorts, as may the tubers of the her- 

 baceous pseonies with scions of the tree pseony. 

 This last is very useful, as cuttings of the Paeonia 

 Motitan remain weak for several years, while 

 roots grafted in July or August will flower the 

 following spring. 



Croicn- Grafting resembles the last kind in 

 requiring the head of the stock to be cut off; 

 but the scion is shaped at the extremity like 

 a wedge flattened on one side, and it is pushed 

 in between the bark and wood of the stock, 

 with its flat side next the wood, till it is stopped 

 by a shoulder with which it is provided, to pre- 

 vent it going in too far. 



In Saddle-Grafting the head of the stock 

 is cut off, and the extremity of the trunk is 

 shaped like a long wedge ; a long slit is then 

 made in the scion, and the divided parts are 

 made to stand astride on the stock. The bark 

 is then pared off at the extremity, so that the 

 two parts may fit quite close ; and a firm liga- 

 ture is applied. 



Herbaceous Grafting is very badly named, 

 as it gives the idea of its being a kind of graft- 

 ing applied to herbaceous plants; whereas, in 

 fact, it only means grafting with the succulent
