76 AMERICAN POMOLOGY. 



for those of their own race ; thus the Dukes and Morellos 

 do well when grafted upon the Morello stocks, whereas 

 the Hearts and Biggarreau sorts do not make a good union 

 upon these stocks, but prefer the Mazzard, which has a 

 freer growth more like their own. Most varieties will do 

 well upon the Mahaleb stock, which is used as a means of 

 dwarfing this fruit, though not a d \varf. Upon the wild 

 cherry, which belongs to quite a different section of the 

 genus, the cultivated varieties will grow, but they form 

 a very imperfect union. 



The peach may be worked upon the plum stock, 

 and is claimed to be somewhat dwarfed by it, and to 

 produce superior fruit. This stock is more congenial 

 to the apricot, which is frequently propagated upon it. 

 Both plums and apricots may be worked upon the peach 

 stock, and they will grow very vigorously, as they will 

 upon the wild plum, but they soon over-grow, and are 

 very apt to break off. When either of these species is 

 used as a stock for the plum or apricot, they should be 

 considered merely as a nursing mother, like the apple or 

 thorn to the pear, which may be wanted to help the cut- 

 ting until it shall be prepared to stand alone, and feed it- 

 self from its own roots. In other words, they should be 

 grafted, not budded, into these uncongenial stocks, and 

 the operation should be performed in the collar or below 

 it, in the root, so that the growing scion may be earthed 

 up, and encouraged to furnish itself with a good system 

 of roots of its own. The success will then depend upon 

 the ability of the scion to emit roots freely. 



We must never forget that in grafting, we are confined 

 to very narrow limits. Our scion must be of a similar
