below the surface of the ground. The cleft is bound with 

 string and then covered with earth, no wax being necessary. 

 Young plants are usually whip-grafted at the crown, either 

 in-doors or out-doors. Grafting the vine is mostly confined 

 to Europe, California, and other countries where the Euro- 

 pean grape (Vitis vinifera] is grown, as that species must be 

 grafted upon some other stock in order to resist the phyllox- 

 era. The common wild frost-grape ( Vitis riparia] is the most 

 popular stock. The union in these cases must be -two or 

 three inches above the ground, to prevent the cion from tak- 

 ing root. The union is wound with waxed muslin, and the 

 earth is heaped about it until it has healed. Grafting may 

 be done out-doors in winter or spring. In the north, winter 

 grafts are likely to be heaved by frosts, and late spring grafts, 

 made as the leaves are pushing, are probably best. 



The vine is frequently inarched, and early in spring it can 

 be budded by ordinary methods. 



Seed-grafting is a curious practice, which may be applied 

 to the grape (see page 90).
