GRAFTING BY APPROACH OR INARCHING. 



the centre of a circle, and three or more of the same, or of allied 

 species, be planted in the circumference, so that their tops may be at a 

 suitable distance for inarching to the centre tree ; then, after the union 

 has been effected, if the parts of the side trees be cut off above the 

 graft, all the sap sent up by their roots will go to the nourishment of 

 the tree in the centre. When the root of one tree is to be joined to 

 another, with a view of strengthening the latter, this mode of inarching 

 is the one generally adopted. 



Terminal inarching consists in heading down the stock, and joining 

 the scion to it, either in the manner of splice-grafting, cleft-grafting, 

 or by saddle-grafting, as exemplified in figs. 226 to 228. The stock

is cut off in the form of a wedge, as in fig. 226, and the scion is cut 



upwards, half way through, for a sufficient length, as in fig. 227 ; then 



the scion is placed upon the stock as in fig. 228, and bound on with 



bast and clay as usual, a ring of bark being taken Fi 229 



off between the graft and the root, as in fig. 228, 



wz, which causes the returning sap to flow through 



the graft into the stock, n, instead of into its own 



root, o. This mode is recommended for grafting 



whenever the stock and the scion are of the same 



size, or very nearly so ; but when the stock is twice 



the size of the scion, the following modification of it 



is preferable : the top of the stock is cut off slanting 



from one side only, as in fig. 229 ; then a long tongue 



is made to the scion, about one-third of its thickness, 



as in fig. 230, and as much of the bark and wood A stock cut over for 



is cut from the back and front of the stock as will inarching when it 



correspond with the width of the tongue on the ^^cion* 1 * "** f 



scion ; when the stock is ready to receive the graft, 



it will appear like fig. 231, q ; there is also a piece cut off the bark of 



the stock at r, tig. 231, but it is not seen in the figure. Then the 



scion is placed across the middle of the stock, as in fig. 232, and bound
