Whip- Graf tmg on the Root. — For this pni'pose, seed- 

 ling stocks are generally used, one or two years old, vary- 

 ing from one fourth to three eighths of an inch in diameter. 

 The graft is always made at the collar, and, therefore, the 

 stems of the plants are cut off at that point ; the small 

 tap-roots and any cumbrous fibres are removed, leaving 

 them about four inches in length (fig. Yl) ; they are then 

 washed clean, and are ready for the operation. The 

 grafter then makes a smooth, even, sloping cut, an inch 

 long, upwards on the collar of the root, 

 A / and in the centi-e of this cut, he makes 

 a slit or tongue, -S, downwards. The scion, 

 which should be three or fom* inches long 

 (fig. 72), is cut on 

 the lower end with 

 a sloping cut down- 

 wards, and similar 

 in all respects to 

 that made on the 

 Btock; a slit, or 

 tongue, is made in 

 it upwards, cor- 

 responding, also, 

 with that on the
