The process is as follows: "Select some of the largest and best berries, or balls, when fully ripe, which is denoted by the withering of the stalk; and separate the seeds from the pulp, and dry them thoroughly in the sun. These should be sown in the following spring, and the produce taken up in October. The tubers will then have nearly attained the size of small plums. The best of these should be selected, and the product of each plant carefully and separately preserved. In the month of April following, they should be planted at a distance from one another of from fifteen to eighteen inches; and, when they rise about two inches from the ground, they should be earthed up slightly with the hoe,—an operation which may be repeated during the season. When they have arrived at maturity, they are to be taken up, keeping the product of each stalk by itself; which product is again to be planted the ensuing spring. A judgment of the properties of the varieties will then have been formed, and those are to be reserved for cultivation which are approved of. It will be found, that, whatever had been the character of the parent stock, the seeds will produce numerous varieties, some white, some dark, in color, with tubers of different forms, round, oblong, and kidney-shaped, and varying greatly in the dryness, color, and farinaceous character, of the flesh."—Low.
Ash-Leaved Early.
Stem nearly two feet in height, erect, with long, smooth, shining, and drooping foliage; flowers very seldom produced; tubers white, roundish, rough-skinned; flesh white, of medium quality. The variety is healthy, and remarkably early; well suited to open culture, but not adapted for growing under glass, on account of its tall habit.
Ash-Leaved Kidney.
One of the earliest of the garden varieties, well adapted for forcing under glass or for starting in a hot-bed, and subsequent cultivation in the open ground. The plant is of spreading habit, and about eighteen inches in height; leaves small, recurved; tubers of medium size, kidney-shaped, white; flesh white, dry, and well flavored. Very healthy. Introduced.
Biscuit. Law.
Plant two feet and a half high, spreading; leaves rather rough, large, and of a pale-green color; flowers whitish; tubers rather small, round, smooth, and of a light-brownish color. A very healthy variety, mealy, well flavored, and quite productive. The plants do not decay, nor do the tubers attain full maturity, until nearly the close of the season: the latter are, however, of good quality, and in perfection for the table soon after being harvested.
Black Chenango.
Black Mercer.
Plant vigorous, and generally of healthy habit; tubers nearly of the form of the Lady's Finger, but of larger size; skin very deep purple, or nearly black; flesh purple, both in its crude state and when cooked; quality good, usually dry, and of good flavor.
