OF PROPAGATION BY GRAFTING.

bud ; the leaves are stripped off from twenty to 

 twenty-four lines down the extremity, leaving, how- 

 ever, two pairs of leaves opposite, and close to the 

 section of fracture, which leaves are of great import- 

 The shoot is then split with a very thin knife 



ance. 



between the two pairs of leaves {fig. 29, a,) and to 

 the depth of two inches. The scion is then prepared 

 (6) : the lower part, being stripped of its leaves to the 

 length of two inches, is 29 



cut, and inserted in the 

 usual manner of cleft- 

 grafting. 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 fifteendays 

 this cap is removed, 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."
