Isabella. — Bunches large. Berries large and oval. Skin thin, of a dark purple colour, almost black, and covered with bloom. Flesh tender, juicy, sweet, and vinous, with a musky flavour.

This is a variety of Vitis Labrusca, a native American grape, cultivated in the open air in the United States, both for the dessert and for wine; but it is not of much account in England.

Ischia (Noir Precoce de Genes; Uva di tri volte).— The bunches and berries of this variety very much resemble those of Black Cluster; but the fruit ripens as early as that of Black July, and is very much superior in flavour to that variety. Berries medium sized, black, very juicy, sweet, and vinous. The vine is very vigorous and luxuriant in its growth, and bears abundantly, if not pruned too close. In Italy it produces three crops in a year by stopping the shoot two or three joints beyond the last bunch just as the flower has fallen and the berries set; new shoots are started from the joints that are left, and also bear fruit, and these being again stopped, a third crop is obtained.

This variety succeeds admirably against a wall in the open air.

Ingram's Hardy Prolific Muscat.—Bunches long and tapering, not shouldered, from nine inches to a foot in length. Berries medium size, perfectly oval, and well set. Skin quite black, covered with blue bloom. Flesh moderately firm, juicy, sugary, and with a fine piquant and rich flavour, having a faint trace of Muscat.

This is an excellent hardy grape, and remarkably prolific. The wood is very short-jointed, and the vine succeeds well in a cool greenhouse. It has all the appearance of being a good out-door grape.

Jura Frontignan (Muscat Noir de Jura).—Bunches long and tapering, very slightly shouldered, and larger than those of Black Frontignan. Berries above medium size, oval, and well set. Skin deep purplish-black, covered with thin blue bloom. Flesh tender, very juicy, richly flavoured, and with a fine, but not powerful, Muscat aroma.

This is a valuable grape. The vine is a prolific bearer; the wood short-jointed; and will be well adapted for growing in pots.

July Muscat (Muscat de Juillet).—This is a very early variety, having a distinct Muscat flavour. It was intro-duced by Mr. Rivers, who describes it as follows:— Berries round, purple; of medium size; rich, juicy, and excellent. This grape will ripen on a wall, as it is one of the earliest of its race, and is well adapted for pot culture in the orchard-house.
