 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 stock is in any de- 

 gree larger, the graft must 

 be placed towards one side, 

 so that the line between the 

 bark and wood may exactly 

 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 grafting, 

 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 

 the place of union, completes the 

 work. When the stock and graft 

 are very nearly of equal size, this is a very perfect mode of
