665. Herbaceous- grafting for shoots with opposite leaves (fig. 220). In 

 the middle of the shoots, be- 

 tween two opposite eyes, an 

 angular and longitudinal inci- 

 sion is made, and a small por- 

 tion of the stem cut out from 

 one side to the other. The scion 

 is cut to fit this opening, and it 

 is inserted as in the figure, and 

 bandaged in the usual manner.

 grafting. Annual or Perennial plants (fig. 



221). The period chosen for this mode of grafting is 

 that of the greatest vigour of the plant, that is, some 

 days before its going into flower. The stem of the stock is cut through 

 above a leaf, as near as possible to its petiole, and a slit 

 downwards is made in the section. A shoot is then taken 

 off near the root of the plant to be increased, the end of 

 which is cut into a wedge shape, and is inserted in the slit 

 made in the stock, taking great care of the leaf on the 

 latter ; for it is that which must nourish the scion until 

 it has taken thoroughly, by keeping up the circulation of 

 the sap. A bandage is applied at the juncture, covered 

 with grafting wax as before. When the graft has taken,

667. Grafting herbaceous shoots of succulents (fig. 222). Take a young 

 shoot, and cutting its base to a point or wedge, insert it in a hole or slit made 

 in the stem or leaf of the stock. 



668. Grafting the melon (fig. 223). On the stem of a cucumber, or any 



other plant of the family of 



Cucurbit ace SB, 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

below the fruit. It is in- 

 serted in the cleft made in the stock, always taking care to spare the leaf 

 until the scion has taken. The remaining part of the operation is per- 

 formed in the usual manner, with ligatures and grafting- wax. This mode 

 of grafting succeeds pretty well ; but it has not hitherto been applied 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.
