Much depends upon immediate parentage. A 

 strong, virile variety, that adapts itself to a great 

 range of conditions, may be expected to give more 

 satisfactory and uniform results than one which has 

 obvious points of weakness and which does not adapt 

 itself to various environments. We turn instinctively 

 to the Concord, for this is preeminently the strong- 

 est type of American grape. No other grape has 

 given us such a famous brood. There are nearly 

 or quite fifty named pure seedlings of it, among 

 which are such varieties as Worden, Moore Early, 

 Eaton, Hayes, Cambridge, Rockland, Cottage, Cole- 

 rain, Esther, Lady, Pocklington and Victoria. These 

 run through deep black -purple to red and white, 

 and all of them possess many strong points, espe- 

 cially in vigor and productiveness. As one parent 

 of hybrids and crosses. Concord has given us Ni- 

 agara, Moore Diamond, Brighton, Lady Washing- 

 ton, Jefferson, Conqueror and others. It has been 

 said that Concord blood has run out, but in the 

 presence of such a family as this, some members of 

 which are very recent, I am forced to conclude that 

 it is the most desirable single stock upon which to 

 breed, or from which to take pure seedlings. 



About three hundred varieties of grapes have been 

 named and prominently disseminated in eastern Amer- 

 ica. Of these, over one -third are pure Labruscas, 

 nearly one -third are hybrids, .about one -fifteenth are 

 aestivalis and one -fifteenth riparia, the remainder being 

 of unknown origin. Of the hybrids, over half con- 

 tain foreign blood. It is interesting to note, in the
