looked after. Soon after spring grafting, the stocks which 

 have been side-grafted are headed down by degrees, leaving 

 them at last a heel of four inches in length. With subjects 

 grafted in the end of summer, the heading down of the stock 

 is completed after winter. The heel serves for fastening up 

 the scion in the early stages of its development. It is removed 

 after a year's growth. If the object be to produce a lateral 

 branch, the development of the scion is promoted by a 

 notch (Z) made over the place of its insertion, and by cutting 

 away the branches growing above it. A stake or prop is 

 useful to fasten the young graft to. 



Grafting by Inlaying. — General Directions. 

 Formerly known under the name of grafting a la Pontoise, 

 this method was employed specially for the propagation of the 

 orange-tree and certain shrubs ; at the present day it is applied 

 to a greater number of plants. The establishment of Simon- 

 Louis, at Metz,has extended its use to almost all kinds of trees 

 and shrubs. The principle of the operation is to inlay the 

 scion, which is cut with a triangular face, in the stock so as to 

 thoroughly exclude the air. The proper seasons are in spring 

 when the sap begins to flow (although one may also graft in 

 summer, using semi-herbaceous scions), and in August and 

 September with woody scions. The time to be preferred is 

 about the end of March and in April. The stock is prepared 

 beforehand, or at the time of grafting, so that the scion maybe 

 placed on a fresh cut. For spring grafting, the scion-branches 

 are cut in winter and kept in soil or sand in a shady place. It 

 will also ans ver to cut them from the parent tree a few days 

 before grafting. In summer grafting they should not be cut 

 until immediately before they are wanted. The scion, which 

 .should have two or three eyes, is cut at the lower part with a 

 wedge -like or triangular face, and is inlaid upon the stock in
