Isabella (Plate XX) is now of little more than historical inter- 

 est, it having been one of the mainstays of American viticulture. 

 In appearance, the fruit of Isabella is fully as attractive as that 

 of any black grape, the clusters being large and well formed and 

 the berries glossy black with thick bloom. The flavor is good, 

 but the thick skin and muskiuess in taste are objectionable. The 

 grapes keep and ship well. Isabella is surpassed in vine char- 

 acters by many other kinds, notably Concord, which has taken 

 its place. The lustrous green, ample foliage which remains 

 late in the season, and the vigor of the vine, make this variety 

 an attractive ornamental, well adapted for growing on arbors, 

 porches and trellises. The origin of Isabella is not known. 

 It was obtained by William Prince, Flushing, Long Island, 

 about 1816 from Mrs. Isabella Gibbs, Brooklyn, Xew York.
