Frost Gage is too small for market purposes and moreover the fruit withers rather quickly after picking; the quality is above the average. The plum is not a Gage, only green fruits being entitled to this name. At one time this was one of the most popular commercial varieties in the Hudson Valley, but because of its susceptibility to black-knot it has lost favor with growers. Downing in 1838 traced the history of this variety to a tree standing on the farm of a Mr. Duboise, Dutchess County, New York, Mr. Duboise stating that the original had been planted by his father. It is doubtful if this is the first tree, however, for in 1849 Charles Hamilton of Canterbury, Orange County, reported trees of Frost Gage thirty to forty years old on his place. Tree of medium size, upright, very productive; branchlets thick; leaves flattened, oval or obovate, one and one-half inches wide, two and three-quarters inches long; margin crenate or serrate, with few, small, black glands; petiole short, usually with one or two glands; blooming season intermediate, short; flowers appearing after the leaves, white, with a little yellowish tinge; borne on lateral buds and spurs, singly or in twos. Fruit late; about one and one-eighth inches in diameter, roundish, dark purplish-black, covered with thick bloom; stem slender, persistent; skin tough, sour; flesh greenish-yellow, juicy, firm, sweet, mild; fair to good; stone clinging, small, irregular-ovate, somewhat oblique.

Furst would undoubtedly be well worthy of very general cultivation in plum orchards were it not for the fact that it is very similar to the Italian Prune. The two fruits differ only in season, the Furst being a few days earlier, and in the tendency of the variety under discussion to shrivel about the neck. It may be that Furst will succeed in some localities where the Italian Prune is not a success.
