ART. 1. On Grafting. 



GRAFTING is performed in various ways, although the 

 principle is the same in each, which is to unite the inner 

 rind, or bark, of the scion, or graft, with that of the stock, in 

 such a manner, that the graft becomes a part of the stock, by 

 which it is fed and nourished, in precisely the same manner 

 as the bud, before spoken of. 



Whip grafting. The most common mode practised on 

 fruit trees is exemplified in the preceding cuts, which is per- 

 formed early in the spring, before vegetation takes place, or 

 the sap is in motion. The grafts, 1 and 2, are taken from 

 the tree of the last year's shoots, generally before the time of 

 grafting, about the latter end of February, and are kept in 

 earth in the cellar, or laid in, covered with earth, by the side 

 of a fence, or other sheltered place, to keep them fresh, and 

 from shrivelling, at time of grafting, which is just before the 

 sap rises. They are cut into three eyes, or buds, and pre- 

 pared, as shown in Fig. 1, by cutting half the side of the 

 graft off, in a slanting manner ; the stock is then prepared, by 

 taking off the head at a smooth place, and cutting a piece of 

 the bark and wood, in a slanting manner, upwards, as repre- 

 sented in Fig. 3, so that the graft will exactly^/; and that 

 the inner bark of the graft and stock meet in such a manner 

 that a union may take place when the sap rises, by the granu-
