This grafting is done after the bark begins to peel in early spring when the leaves begin to start. The stock is cut back as in cleft-grafting, but no cleft is made. The bark is slit downward in two or three places as shown in Fig. 53. The scion is cut at lower end into a thin wedge with a notch on top that rests on the top of the stub when the wedge is shoved down to place.

The scions do not need tying in our climate, if, after waxing, the surface is covered by winding with a cotton strip. If tied under the wax the string is liable to do injury as the size of the stock and scion increases. As growth is secured the same season this is a certain method of working small and large stocks of several species. Where limbs have been broken on fruit and ornamental trees the writer has inserted bark grafts that soon repaired the injury.
