to varying conditions. Its use in this experiment is for purposes 

 of comparison as to its behavior on different stocks rather than 

 with the hope of correcting defects of adaptability. 



Delaware. — Delaware is the standard in quality of all Ameri- 

 can grapes found on the markets. The variety, however, makes a 

 very slow growth and is very capricious in certain soils. It would 

 be a boon, indeed, if grape-growers could overcome these faults 

 by grafting. 



Goff. — Goff, a variety originating at this Station, is hardly 

 surpassed in fruit characters but falls far short in bunch and vine 

 characters. It was hoped that these might be improved by 

 grafting. 



Herbert. — Herbert, another of Rogers' hybrids, very similar to 

 Barry in characteristics, is as near perfection in fruit characters 

 as we have yet attained in the evolution of American grapes but 

 is very capricious as to soils. It was especially hoped that this 

 splendid grape would do better grafted than on its ovm. roots. 



lona. — lona is unsurpassed among American grapes for deli- 

 cacy and sprightliness of flavor, keeping quality, and in making 

 wines and champagne. But to be grown at all well it must have 

 a soil exactly suited to its needs. It requires a deep, dry, sandy 

 or gravelly clay and will not thrive on black loams or on poor 

 sands or gravels — hence, the attempt to graft it on a stock more 

 adaptable to soils. 



Jejferson. — Jefferson is a cross between Concord and lona, the 

 good qualities of both parents showing. Unfortunately, it is a 

 little too late and a little too tender to cold for a commercial 

 variety, faults which it was hoped might be remedied by growing 

 it on other roots than its own. 



Lindley. — All concede that Lindley is the best one of the red 

 grapes among the hybrids gro^vn by Rogers. Yet it is little knoAvn 

 commercially because of precariousness in bearing and lack of 

 adaptation to some soils. Top-working might help overcome these 

 defects. 



Mills. — Of all our cultivated grapes. Mills probably varies 

 most under different cultural conditions and because of this is
