the Plum upon Mirabelle Plum seedlings, the 

 Cherry upon the Cerasus Mahaleb, and, in 

 general, any tree upon any other kindred tree 

 of slower or smaller growth. There is also, 

 we may remark here, another mode of produ- 

 cing dwarf-trees, by root-pruning, which we 

 shall describe under the head of Pruning. 



The stock and the graft (scion or bud,) exert 

 influences upon each other, mutually. Some 

 of the influences of the stock have just been 

 mentioned, see 3d, 5th, 6th, and 9th uses of 

 grafting above described. The stock often 

 affects the size and flavor of the fruit borne 

 by the graft. Thus the Saint Michael pear is 

 larger, fairer, and better flavored, in our climate, 

 when grown upon the Quince stock. Of a 

 graft or a stock, either may communicate its 

 own diseases and infirmities to the other. It 

 is pretty well established, also> that stocks bear- 

 ing early fruits, have an influence in acceler-

 made to grow upon them by grafting. The 

 graft is also said, in some cases, to affect the 

 appearance of the bark of the stock, and also 

 the form of growth in its roots. 



It may be remarked here, that many of the
