As one of the parents of a number of valuable hybrids cultivated in 

 American vineyards, Muscat Hamburg is illustrated and described in The 

 Grapes of New York. It is described below in detail that grape- breeders 

 may detect any of its characters transmitted to its offspring. The grapes 

 and vines described here were grown under glass, as the variety cannot be 

 grown out of doors in eastern America. 



Muscat Hamburg is a forcing grape only and is apparently unknown 

 in the grape-growing districts of Europe. It is said to grow better grafted 

 on Black Hamburg than on its own roots. 



Seward Snow of Wrest Park, Bedfordshire, England, originated 

 Muscat Hamburg more than a half century ago from seed of Black Ham- 

 burg fertilized by White Muscat of Alexandria. It was placed on the 

 grape list of the American Pomological Society fruit catalog for 1862 as an 

 exotic recommended for growing under glass. 



Vine very vigorous, tender, productive. Canes long, numerous, slender to medium, 

 light brown, slightly darker at nodes which are enlarged and somewhat flattened ; inter- 

 nodes short '.,0 medium; diaphragm thick; pith nearly large; shoots glabrous; tendrils 

 inclined to dehisce early, intermittent or frequently with only one tendril present with 

 vacancy on either side, long, bifid to trifid. 



Leaf-buds large, long to medium, inclined to thick. Leaves medium to large, 

 intermediate in thickness; upper surface light green, dull, somewhat smooth; lower 

 surface slightly lighter green than upper surface, faintly pubescent, densely hair)-; lobes 

 usually five with terminus acute to acuminate; petiolar sinus of average depth, medium 

 to narrow, rarely closed or overlapping; basal sinus intermediate in depth; lateral sinus 

 deep; teeth very irregular in depth and width, some teeth approaching a tendency to 

 lobing. 



Fruit ripens the latter part of October under glass, keeps unusually well. Clusters 

 very large to medium, long, broad, tapering, frequently single-shouldered but sometimes 

 double-shouldered, rather loose; peduncle intennediate in length, medium to rather
