IV hip-grafting large stocks is fre- 

 quently practised, and is a very success- 

 ful manner of operating upon quite 

 large trees in the nursery row. The 

 sloping cut upon the stock, and the 

 forming of the graft, is the same as in 

 the ordinary American whip tongue- 

 grafting, except that one side of the 

 stock, opposite that on which the graft 

 is placed, should be cut away upon the 

 same slope as the grafted side, as indi- 

 cated by the dotted lines in Fig. 6. As 

 soon as the graft has taken, and com- 

 menced expanding its leaves and send- 

 ing out shoots, it will be necessary to 

 rub or cut olf all shoots between the ball 

 and the ground, if it is a small stock, or 

 all those which would rob it of a princi- 

 pal share of nourishment, if upon a large 

 tree. If the scion or stock is very 

 weak, it is usual to leave one or two 

 other buds for a time, to assist in 

 drawing iip the sap. Wlien the graft 

 has made a growth of two or three 

 inches the ball of clay may be remov- 

 ed, and if the graft is securely united, 

 the bandage may be loosened and re- 

 tied, or it may be cut partially away at 

 the back of the graft, for the purpose of 

 permitting the expansion of growth, 

 that otherwise would soon be checked, 

 and cause the graft to break off. In the 

 use of the wax-cloth strips, passing the 

 knife at the back and cutting the tie is 

 all that is requisite. Early in August 

 the angle left at the top of the stock 

 should be cut off smoothly, in order to 

 allow the bark of the stock and the scion 

 to heal neatly over the whole wound. 



Though it is little attended to in 

 common practice, the amateur will be 

 glad to know that the success of a graft 

 is always greatly insured by choosing 

 the parts so that a bud is left near the 

 top of the stock, k, Fig. 4, and another 

 near the bottom of the scion, I. These 

 buds attract the rising sap to the por- 

 tions where they are placed, form woody 

 matter, and greatly facilitate the union of 

 the parts near them ; the upper part of
