with many that cannot be readily grown from cuttings 

 or layers, and for which seed cannot be used, either 

 because they cannot be readily obtained, or because they 

 do not reproduce the desired varieties. 



Grafting is performed just as the growth of the 

 stock is beginning, and while the cion is still dormant. 



The cions are made from 

 the last season's growth, and 

 are from three to four inches 

 long, with a bud near the 

 upper end. If in the right 

 condition, for success in 

 grafting we only need to 

 bind the cion upon the stock 

 in such a way that the cam- 

 bium of one will at some 

 point be in contact with 

 that of the other, and coyer 

 the cut surface so that they 

 will not suffer from evap- 

 oration. 



The more common kinds 

 of grafting are, first, the 

 splice, in which, as the name 

 indicates, the stock and cion 

 (which should be of about 

 the same size) are cut at 

 their ends with a long bevel, and are bound firmly 

 together ; second, the tongue or whip graft (Fig. 101), 

 which differs from the splice only in having the ends so 

 split as to form tongues, and they are then put together 

 80 that the tongues of one will be in the split in the 

 other, and bound in place ; third, the cleft graft, which 

 in used upon large stocks, by inserting a cion with its 

 lower end cut wedge shape, into a cleft in the middle of 

 the top of the stock, which has been cut off at right
