Early and hardy, but too unproductive, and bunch too small. Bunch small, shouldered; berry round; of very good quality for its season; black, juicy. Ripens as early as Hartford Prolific. CLASS 4.--_Varieties of good quality, but subject to disease._ CATAWBA. This well known grape was brought into notice by Major ADLUM, of Georgetown, D.C., who thought he had, by its introduction, conferred a greater boon upon the American people, than if he had paid the national debt. For the last ten years, it has been so much subject to disease, that it cannot be recommended any longer, except for some peculiar locations. It is said to be healthy in northern Illinois and Iowa, where it will not stand the winter, however, without protection. Bunch large, moderately compact, shouldered; berry medium, red, covered with lilac bloom; juicy, pulpy, sweet, somewhat astringent, of good flavor. A fair grape for the table, and makes a good wine, resembling Hock, but subject to mildew, rot and leaf-blight. DIANA. A seedling of the foregoing, raised by Mrs. DIANA CREHORE. Perhaps one of the most variable of all the grapes, being very fine one season, and very indifferent the next. Bunch large and long, compact, shouldered; berry pale red, round, somewhat pulpy; thick skin; juicy and sweet, with a peculiar flavor, which DR. WARDER very aptly calls "feline;" others call it "delicate." Very productive, but subject to leaf-blight, mildew and rot; although perhaps not so much as the Catawba. Ripens about a week earlier. ISABELLA. Unworthy of cultivation here, but said to be better at the North. Bunch long, loose, shouldered; berry medium, oval, black; tough pulp, with a good deal of acidity, juicy, and a peculiar flavor. Ripens irregularly. Subject to rot and leaf-blight. GARRIGUES. Closely resembling the Isabella, but ripens more evenly, and is of somewhat better quality. TOKALON. Bunch large, loose, shouldered; berry black, large, sweet and buttery; of very good quality, but very much subject to disease. Ripens somewhat later than Catawba. ANNA. Bunch large and loose; berry pale amber, covered with white bloom; sweet, tolerable flavor, but poor bearer, and subject to mildew. Ripens about same time as Catawba. ALLEN'S HYBRID, (ALLEN'S WHITE HYBRID). Bunch large and loose, shouldered; berry medium, nearly round; white, without pulp, juicy and delicious; quality very good, but variable; sometimes best. Said to be a hybrid of Vitis Labrusca and a foreign grape, raised by J. F. ALLEN, Salem, Massachusetts, and is really a fine grape, although too tender and variable for extensive vineyard culture. Ripens about two weeks before Catawba. CUYAHOGA (COLEMAN'S WHITE). Much recommended in Ohio, where it originated, but unworthy of culture here, being a poor grower, a shy bearer and very much subject to leaf-blight. Bunch medium, compact; berry dirty greenish-white; thick skin; pulpy, and insipid. DEVEREAUX.
