HERBACEOUS GRAFTING. 



of fracture, which leaves are of great importance. The shoot 

 is then split with a very thin knife between the two pairs of 

 leaves (Fig. LI. a), and to the depth of two inches. The 



scion is then prepared (fe): 

 the lower part, being stripped 

 of its leaves to the length of 

 two inches, is cut, and in- 

 serted in the usual manner 

 of cleft-graiiing. They may 

 also be grafted in the lateral 

 manner (c). The graft is tied 

 with a slip of woollen, and a 

 cap of paper is put over the 

 whole, to protect it from the 

 sun and rain. At the end of 

 fifteen days this cap is re- 

 moved, and the ligature at 

 the end of a month; at that 

 time also the two pairs of leaves {a), which have served as nurses, 

 are removed. The scions of those sorts of Pines which make 

 two growths in a season, or, as the technical phrase is, have a 

 second sap, produce a shoot of five or six inches in the first 

 year : but those of only one sap, as the Corsican Pine, 

 Weymouth Pine, &c., merely ripen the wood grown before 

 grafting, and form a strong terminating bud, which in the 

 following year produces a shoot of fifteen inches, or two feet."

With regard to inarching, which was probably the most 

 ancient kind of grafting, because it is that which must take 

 place accidentally in thickets and forests, it differs from 

 grafting in this, that the scion is not severed from its parent, 

 but remains attached to it until it has united to the stock, to 

 which it is tied and fitted in various ways ; the scion and stock 

 are therefore mutually independent of each other, and the 

 former lives upon its own resources, until the union is com- 

 pleted. 



In practice, a portion of the branch of a scion is pared away, 

 well down into the alburnum ; a corresponding wound is made
