D'ALBEET'S VARIETIES 



By this method we may propagate many hard-wooded evergreens 

 and herbaceous stems, sueh as the young shoots of Pelargoniums, 

 Melons on Gourds and Cucumbers, Tomatoes on the stems of Potatoes, 

 Sunflowers on the Jerusalem Artichoke, &c. For the latter, shading is 

 indispensably necessary. 



Cleft Grafting with, two Scions (Fig. LIX.). — The stock is out 

 horizontally, then split across the middle into two equal parts, or 

 nearly so, without regarding the medullary sheath. The operations 

 are similar to those required for Fig. LVIL, excepting that the stock 

 is cut across horizontally, and two scions are inserted. This mode is

only used for stocks that are too large for one scion, and too smaU. to be 

 cleft for four. In many cases we out back one of the grafts when both 

 take, if their growth^ are likely to prove injurious to each other. 

 This, however, is not the case when the grafts are intended to form 

 either fan-trained, or vase-shaped trees. "We also use the method for 

 grafting the strong stem of a bad Vine with a better variety ; but the 

 wood of the Vine being flexible, it is necessary to bind, securely, the 

 parts operated upon ; when the graft is above ground, and exposed to 

 the sun, we cover the wound with resinous composition, (p. 331,) held 

 together by a piece of cloth, in order to prevent the composition from 

 being loosened, or thrown oflf by the flow of sap. Vines should be
