INAEOHING. 823 



ih the branch of a stock ; " tongues " are made in each wound 

 so that they will fit into each other ; and the liber and alburnum 

 of the two being very accurately adjusted, the whole are firmly 

 bound up ; grafting clay is applied to the wound, and the 

 plants operated upon are carefully shaded ; in course of time 

 the wounds unite, and then the scion is severed from its 

 parent. Gardeners consider this the most certain of all the 

 modes of grafting, but it is troublesome, and only practised in 

 difficult cases. The circumstances most conducive to its 

 success are, to stop the branch of both stock and scion under 

 operation, so as to obtain an accumulation of sap, and arrest 

 the flow of sap upwards ; to moderate the motion of the fluids 

 by shading ; to head back the stock as far as the origin of the 

 scion, as soon as the union is found to be complete ; and at the 

 same time to remove from the scion a part of its buds and 

 leaves, so that there may not be a too rapid demand upon the 

 stock, at a time when the line of union is stUl imperfectly 

 Consolidated. 



One of the most happy applications of the art of inarching is that by 

 means of which old naked branches are clothed with new Wood. It is well 

 known that if herbaceous grafting or inarching (Fig. LII.) is employed 

 with the Pear-tree, in the month of July, the scion will have "taken " in 

 three weeks, and will reach the length of perhaps fifteen inches before 

 autumn. Of this the French gardeners take advantage in a very 

 ingenious way, in order to restore to fruit-trees their lost Umbs, or t» 

 complete the symmetry of form on which they so justly pride them- 

 selves. Mr. Thompson, in an account of a visit to the gardens near 

 Paris {Journ. Sort. Soc. ii. 239), says that he viewed with astonish- 

 ment some trees thus treated at Corbeil, near Fontaineblean. " They 

 were fine trees, covering a waU, and trained horizontally. But they 

 were not planted when young, and trained progressively in order to 

 produce this regularity. On the contrary, they were planted when 

 large and irregularly grown, having in some places a redundancy, in 

 others a deficiency, of branches. Various means are frequently resorted 

 to with the view of supplying branches where wanted; such as notching 

 budding, or side-grafting the stem; but here the desiderata were 

 obtamed by marching the ffrowing extremities of adjoining shoots to 

 the parts of the stem whence the horizontals should proceed. Suppos- 

 ing the branches of a tree are trained horizontaUy a foot apart, with 

 the exception of some where the buds intended to produce branches did 

 not break, as is often the case ; then a shoot, a, is trained up, and,
