CULTURE OF THE GRAPE. 33 



Rogers. Mr. Allen's White Hybrid is another example 

 where hybridization seems to be evident. 



On the other hand, many seedlings which are heralded 

 as hybrids, can, in truth, neither lay claim to any foreign 

 blood or native merit. In the "Horticulturist," vol. i. 

 p. 343, a writer says, " I have a large number of seedling 

 grape-vines, hybrids between the different foreign kinds 

 and the Isabella and Catawba, which promise well, and 

 will be in bearing next year." If they had been genuine 

 hybrids, they would not have remained unknown to the 

 world for twenty years. 



In performing this experiment of hybridizing, the fol- 

 lowing rules are to be observed: Select such varieties, 

 either native or foreign, as have some known excellence, 

 such as vigor, good quality, earliness, size, &c. A Black 

 Hamburg and an early Creveling would be a good exam- 

 ple ; also the early and excellent Delaware with the large 

 and vigorous but late Union Village. But the Union Vil- 

 lage with the Isabella would not be a good example, 

 because they have a similarity of characteristics, and are 

 both late. 



The object is to bring together different excellences. 

 Having determined the varieties beforehand, if there should 

 be a difference in the time of inflorescence, the later kind
