10 HORTICULTURAL MEMOIRS. 



the same medium. That process which has na- 

 turalized the Canna Indica, might go far to put 

 us in possession of many other desirable objects, 

 at least in cases where, like the melon, the gene- 

 rations can be rapidly repeated, and where the 

 produce goes hand in hand with each successive 

 generation. Thus, possibly, even the elegant 

 Pine of Norfolk Island, might become a British 

 tree, although the toil of many years would be 

 requisite for effecting such a purpose. 



An economical object which depends on this 

 property of plants, remains yet to be noticed. 

 This, which is still more in our power, is proba- 

 bly of more consequence than either of those a- 

 bove mentioned ; I mean the perfect naturaliza- 

 tion of the Vine. It is well known, that from 

 many of the ordinary varieties cultivated in this 

 country, we can always insure a crop of grapes, 

 but not always a crop of ripe ones. From two 

 or three of these, the chance of ripening out of 

 doors is considerable ; from many others it is 

 hopeless. It is not improbable, that by succes- 

 sive sowing of seeds, other varieties might be 

 produced, still more certain of ripening than 

 those which succeed best with us, the Miller 

 and Svveetwater. We should thus acquire pos- 

 session of an article of cultivation of great im- 

 portance, by which a useful addition would be 

 made to the agricultural proceeds of land irt 

 particular situations, and by which we should
