after the wedge has been withdrawn, the projecting angle 

 of the stock sloped off with a knife, and the whole ready for 



the application of the wax. 



Whip grafting is particu- 

 larly applicable to small 

 stocks, or where the graft 

 and stock are nearly of equal 

 size ; and cleft-grafting to 

 stocks considerably larger 

 than the scion. In all cases, 

 where the ? tock is in any de- 

 gree larger, the graft must

 so that the line between the 

 bark and wood may exactly 



., . J . , i J . 



coincide at one point at least 

 in both, as in the cross section of cleft-grafting, fig. 22. A 

 useful implement for the rapid and perfect 

 performance of cleft-grafting, is described 

 in the chapter on implements. 



There are other modifications of grafting 

 which are often useful. In saddle grafti?ig t 

 the stock is sloped off on each side, giving 

 t the form, of a wedge, fig. 23, a ; the graft is split in the 

 middle, and each side thinned away 

 with the knife, as in fig. 23 b, until 

 it will closely fit when placed like a 

 saddle upon it, fig. 24. The most 

 perfect way to fit the graft, is to 

 make a long sloping cut from the 

 outer edge or bark, by drawing the 

 blade from heel to point, till it reach- 

 es the centre of the graft; and then 

 another similar cut completes the 

 acute cavity for fitting the wedge of 

 the stock. A sharp, broad, and thin 

 blade, is needed for this operation. 

 A wax plaster, drawn closely round 

 Fig . 24. the place of union, completes the 

 work. When the stock and graft 

 *re very nearly of equal size, this is a very perfect mode of
