Black Eagle 



(Labrusca, Vinifera) 



The fruit of Black Eagle is of the best, but the vine lacks in 

 vigor, hardiness and productiveness and is self-sterile. Bunch 

 and berry are large and attractive. The season is about with 

 Concord. Black Eagle has wholly failed as a commercial 

 variety, and its several weaknesses prevent amateurs from 

 growing it widely. The variety originated with Stephen W. 

 Underbill, Croton-on-Hudson, New York, from seed of Con- 

 cord pollinated by Black Prince. It fruited first in 1866. 



Vine vigorous, precariously hardy, unproductive. Canes rough, 

 thick, reddish-brown witli light bloom ; nodes enlarged, flattened 

 internodes long; tendrils continuous, long, bifid or trifid. Leaves 

 thick ; upper surface dark green, glossy, smooth to rugose ; lobes five ; 

 terminal lobe acute ; petiolar sinus deep ; lateral sinus wide, narrowing 

 towards top, deep. Flowers open in mid-season, self-sterile ; stamens 

 reflexed. 



Fruit mid-season, keeps well. Clusters large, long, tapering, single- 

 or doul)le-shouldered. compact; pedicel long, slender with few warts; 

 brush sliort, pale green. Beiries variable in size, oval, black, glossy 

 with thick bloom ; skin tender, thin, adherent with wine-colored pig- 

 ment ; flesh pale green, translucent, tender, vinous ; good. Seeds free, 

 one to four, large. 



Black Hamburg 



(Vinifera) 



Black Hamburg (Plate VI) is an old European sort, long the 

 mainstay in forcing-houses in Belgium, England and America 

 and now popular out of doors in California. It is an excellent 

 table-grape but, while it keeps well, its tender skin does not 

 permit its being shipped far, especially when grown out of doors.
