PLANTS MULTIPLIED BY GRAFTING.

grafted on tlie hawthorn or the mountain ash, though 

 much better when grafted on a crab stock. 



a, the Pavia lutea, a plant, which never attains the full size of a 

 tree, cleft-grafted on the horse-chestnut, h, a tree of great size. 

 It is remarkable that the Pavia is much enlarged near the junc- 

 tion c, like a tree near the ground, a circumstance which would 

 not have occurred but for the gi-aft. The bark of each remains 

 distinct, d, the white-lime tree grafted on the European lime 

 tree, e; each growing in diameter according to its particular 

 nature, without any intermixture at the line of graft, c ; a verti- 

 cal section, /, of an almond-tree, /, cleft-grafted on a prunus, g, 

 showing that not one of the characteristics of the two individuals 

 ever passes the line of junction, c, c, any more than a spur grafted 

 on the comb of the cock ever changes its hard horny nature for the 

 soft fleshy nature of the comb. 



When one branch of a growing tree or shrub is grafted 

 to the branch of another growing plant near it, the pro- 

 cess is termed inarching, but this system is seldom prac- 

 tised, except with rare and choice plants. When a bud 

 from one tree is inserted into the bark of another tree, 

 it is termed budding, and this is exceedingly advan- 

 tageous with rose trees, for a fine standard rose may 

 thus be obtained by simply inserting buds of good sorts 

 on a stock of the wild rose or sweetbriar. It is also very 

 useful in filling up the breaches in peach or other fruit 

 trees trained to a wall, which are sometimes occasioned 

 by the decaying of a large branch.
