_Seedless Sultana._--This grape is decidedly one of the most important raisin grapes known. Its bunches are very large, sometimes weighing five pounds each. The berries are round and seedless, the size of large peas, of a green color, which, when the grape ripens, turns bright amber yellow, with small brown spots. The leaves are large and very entire, and more yellowish than those of the Muscat. The growth of the vine is upright, with erect or climbing branches. This grapevine in order to bear must be pruned long, and should properly be staked from four to five feet high. The yield of the Sultana is very heavy, and as much as sixteen tons of fresh grapes are frequently harvested from an acre, provided the soil is the very best possible. The grapes begin to color and sweeten several weeks before the Muscat, but they become fully ripe later than this variety, and are on that account not as extensively grown as they certainly deserve to be. For districts with long summers and autumns the Sultana will prove a very profitable and desirable grape. The native home of the Sultana is Asia Minor. There it is grown principally around Smyrna and in several of the islands in the Archipelago. In California only few Sultana vineyards are planted; still there is undoubtedly a great field for this grape where the seasons are long enough to allow of its perfect ripening. The raisins are light in color and somewhat acid, but with no particular flavor, and in this respect are inferior to the Muscats and the Currants. They are produced either by dipping, as is done in Smyrna, or by sun-drying, as we do in this State. If the dipping process is used, the grapes must be very ripe, else they will turn reddish and dark and lose quality. In California the Sultana grape does well, and only seldom produces seeds. In Eastern Mediterranean countries, except in the few favored spots of Smyrna, or in some of the Islands, this variety rapidly deteriorates and becomes seed-bearing, which of course entirely ruins its usefulness. The Seedless Sultana was first brought to California by Colonel Agoston Haraszthy in 1861. _Black Currant._--This variety is but little known in this State. The growth is erect and climbing. The bunches are long, narrow and cylindrical, with heavy shoulders. The berries are small, of the size of peas, seedless and black, very sweet and with a peculiar aroma not found in any other variety. The Black Currant should be pruned short, and the young branches require staking in order to bear well. The home of the Black Currant is the Grecian Islands as well as Morea, especially around Patras. Zante, Cephalonia and Ithaca all produce Currants of the highest quality.
