GRAFTING AND BUDDING.

be continued down the entire length of the stock, and renewed 

 in the coarse of the season or in the following spring if the 

 deformity continnes. 



By a similar process, in order to promote the vigour of the 

 tree, we utilise the swelling of the pear when grafted on the 

 quince. The pear-tree (D), which is disproportionally larger tnan 

 the stock on which it has been grafted,, has become deficient 

 in vigour and fertility. As a remedy for this, small longitu- 

 dinal incisions are made in the swelling (F) ; good soil is then 

 heaped up around it (as at B, B), kept moist by watering, and 

 covered with straw, litter, or tan. Instead of soil, river sand 

 may be used, as this does not soon become dry, and maintains a 

 constant coolness. Before long, rootlets will issue from the 

 fissures in the swelling (F) : these will soon become roots, 

 and convey a direct supply of nutriment to the tree. The 

 pear-tree (D), thus brought upon its own roots, will acquire 

 fresh vigour, while the quince-stock (E) will be superseded, 

 and finally disappear along with its roots. 



TREES, SHRUBS, AND BUSHES THAT MAY BE 

 MULTIPLIED BY GRAFTING. 



It is not sufficient to know how to graft; it is necessary 

 also to know what plants are adapted for grafting, the kind of 

 stock and the mode of operating suited for each case. These 

 will be described in this chapter, which is devoted to an enu- 

 meration of the principal trees and shrubs which grow in tha 

 climate of France. The methods of grafting are given in the 

 order of their relative importance. The mode of reproducing 

 the stock is also indicated, and some observations, the result 

 of experience, are added. "We say nothing of the dwarf cherry, 

 the Deutzias, willows, Alaternus, fig-trees, gooseberries and 

 currants, pomegranates, hazels, &c, the varieties of which are
