Different Modes of Grafting. 



be increased, the end of which is cut into a wedge shape, and is 

 inserted in the slip made in the stock, taking great care of the 

 leaf on the latter ; for it is that which must nourish the cion until 

 it has taken thoroughly, by keeping up the circulation of the sap. 

 A bandage is applied, and the junction covered with grafting- 

 wax, as before. When the graft has taken, which is ascertained 

 by its growth, the ligature is removed, and the old leaf, and the 

 shoots from the stock below the graft, are re- 

 moved. M. Tschoudy grafted in this manner 

 artichokes upon cardoons, and other plants on 

 their congeners. 



5. Grafting on Succulents ,• Greffe des Plantes 

 Grasses, {fig. 60.) — Take a young shoot or leaf of 

 a succulent plant (for example, of a cactus or 

 opuntia), and, cutting its base to a point or wedge, 

 insert it in a hole or slit made in the stem or leaf 

 of another species, but of the same genus. 



6. Grafting the Melon; Greffe du Melon. 

 (Jig. 61.) — On the stem of a cucumber, or any other plant of the 

 family of Cucurbitacese, but having some analogy with the melon, 



choose a vigorous part of a shoot having 

 a well-developed leaf. In the axil of 

 this leaf an oblique cut is made, of half its 

 thickness. The point of a melon shoot, 

 so far developed as to have its fruit quite 

 formed, is then cut off, and pointed at 

 its end, 2 in. below the fruit. It is in- 

 serted in the cleft made in the stock, al- 

 ways taking care to spare the leaf until 

 the cion has taken. The remaining part 

 of the operation is performed in the 

 usual manner with ligatures and grafting-wax. This mode of 

 grafting succeeds pretty well ; but it has not hitherto been ap- 

 plied to any useful end. Tomatoes may be grafted in this 

 manner on potatoes, and it is said that potato plants thus treated 

 produce good crops both of potatoes and tomatoes. 



Grafting-wax may be formed with turpentine, bees' wax, resin, 

 and a little tallow, melted together. It may either be put on in 

 the same manner as grafting-clay, but not more than a quarter 

 of an inch in thickness ; or it may be very thinly spread upon 

 cotton cloth, and used in shreds like sticking-plaster. In this 

 last state it serves both as a ligature for retaining the escutcheon 

 or scion in its place, and as a covering for excluding the air. 

 In very delicate budding and grafting, fine moss and cotton 

 wool are frequently used as substitutes for grafting-clay or graft- 

 ing-wax ; the moss or cotton being tied firmly on with thread 

 or strands of bast matting.
