GRAPTING AND BUDDING.

of trees tlained in certain forms by approach -grafting, with- 

 out any detriment to the well-being of the subjects thus 

 treated (see pp. 58, 59, 60, 61). 



Restoration of a Bruised or Cankered Stem (see p. 53). — 

 When branches have grown from the base of the tree, they 

 are grafted on the stem, by inarching, above the diseased part. 

 If the tree has no branches at the base, a young vigorous 

 stock should be planted near it, of a kind analogous to the 

 tree which is to be restored, or of a kind which will not refuse 

 to be grafted on it. This is to be grafted by approach on 

 the injured tree, and, when united to it, will supply additional 

 sap. 



He^latincj a part of a Trained Form (see p. 54). — Here, 

 on a chandelier-palmette, a portion of the figure is wanting 

 and cannot be supplied by a neighbouring branch. In this 

 case a new stock is planted, which is afterwards grafted to the 

 others by approach, and thus supplies the deficiency. Should 

 it not be possible or convenient to plant a second stock thus, 

 scions may be inserted on the bare places of the stem. When 

 the stem is young, buds may be used, but when the stem is 

 thick, we must employ branch-grafting, either by (1) veneering 

 with strips (see p. 86) ; (2) a simple branch (see p. 68) ; or (3) a 

 branch with a heel (see p. 69). By the last method we can 

 insert scions twenty inches in length, furnished with twenty 

 buds ; but we must be careful to prepare them for this opera- 

 tion by disleafing them a week beforehand, and after they are 

 grafted, they should be covered with an envelope of mud and 

 leaves to protect them from the heat. 



The same object would be attained by grafting by approach 

 the branches of the tree itself, or of a neighbouring tree on 

 the bare parts. Approach-grafting applied to horizontal 

 cordons (see p. 62), and the piecing-graft (see p. 63), which 

 unites two subjects distinct from each other, come under the
