and well. When it is desirable to bestow 

 the greatest, possible care upon a scion, the 

 wax composition and also the tip end of 

 the scion may be covered,, in addition, with 

 the gum-shellac composition, which we shall 

 describe under the head of Pruning. 



Scion-grafting may be performed at almost 

 any season of the year, with scions properly 

 kept. A stick of buds (see Bud-Grafting,) 

 may be inserted on the north side of a tree, at 

 budding time, after the mode of side-grafting 

 explained below; and from that time to the 

 first of June, scions may be successfully set. 

 But by far the best time to graft with scions, is 

 from the middle of February, in mild weather, 

 all along until the middle of May, stone- 

 fruits first, and other fruits chiefly in April 

 and May. 



Scions are united to their stocks in several 

 ways. Whatever may be the mode of oper- 

 ating, the principle is always the same as 

 above stated, namely, the sap-vessels of the 

 graft and the stock must be so adapted to 

 each other, that the sap can flow uninterrupt- 

 edly from the one to the other. 



Cleft- grafting, so called, is the mode of sci- 

 on-grafting in most common use. Stocks, from
