224 Principles of Plant Culture. 



388. Grafting Cord is made by soaking balls of com- 

 mon wrapping twine in melted grafting-wax. 



389. Grafting Paper is made by painting thin ma- 

 nil] a paper with melted grafting-wax. For painting, 

 the paper is preferably spread out on a board of the 

 exact size of the sheet; to prevent too rapid cooling of 

 the wax the board should be heated. The wax should 

 be heated hot enough to spread easily, but not so hot 

 that it is absorbed by the paper. Thin muslin or 

 calico is often used instead of paper. 



Grafting paper and grafting cloth should be stored 

 in a cool, moist place to preserve their adhesiveness. 



Many kinds of cion grafting slightly differing in de- 

 tails have been described, but the more important are 

 whip-grafting, cleft-grafting and side-grafting. 



390. In Whip-Grafting (splice-grafting, tongue, 

 grafting) the cion and stock, are both cut off with a 

 sloping cut, about an inch long, after which a tongue 

 is formed on each by splitting the wood longitudinally 

 a short distance (Figs. 107, 108) . The cion is best cut 

 behind a bud, as shown. 



In joining, the tongue of the cion is inserted into the 

 split of the stock, so that the cambium line of the cion 

 and stock (68) coincide on one edge, and the two are 

 crowded together with considerable force, after which 

 the joint is wrapped with a narrow strip of grafting 

 paper or grafting cloth (389), or wound with grafting 

 cord (388). Sometimes the joints are simply tied with 

 rmwaxed cord. 



Whip-grafting is generally used when the stock is 

 little if any thicker than the cion. It is much used by
