GRAFTING. 67 



consists in uniting, the branches of two or more sepa- 

 rate trees, as Dr. Hope's Willows, see;?. 47, and a 

 whole row of Lime-trees in the garden of New Col- 

 lege, Oxford, whose branches thus' make a net-work. 

 This is called grafting by approach. A more common 

 practice, called budding, or inoculating, is to. insert a 

 bud of one tree, accompanied by a portion of its bark, 

 into the bark of another, and the tree which is thus 

 engrafted upon is called the stock. By this mode dif- 

 ferent kinds of fruits, as apples, pears, plums, &c. each 

 of which is only a variety accidentally raised from 

 seed, but no further perpetuated in the same manner, 

 are multiplied, buds of the kind wanted to be propa- 

 gated being engrafted on so many stocks of a wild 

 nature. The mechanical part of this practice is de- 

 tailed in Du Hamel, Miller, and most gardening books. 

 It is of primary importance that the liber, or young 

 bark, of the bud, and that of the stock, should be ac- 

 curately united by their edges. The air and wet must 

 of course be excluded. 



It is requisite for the success of this operation that 

 the plants should be nearly akin. Thus the Chionan- 

 thus virginica, Fringe-tree, succeeds well on the Com- 

 mon Ash, Fraainus excelsior, by which means it is 

 propagated in our gardens. Varieties of the same 

 species succeed best of all ; but Apples and Pears, two 

 different species of the same genus, may be grafted on 

 one stock. The story of a Black Rose being produced 

 by grafting a common rose, it is not worth inquiring
