The Harrison, if it should do as well in the future as it has done in the past, bids fair to become _the_ potato for general cultivation. It has yielded in this section, on soil of moderate fertility, with ordinary culture, one peck to the hill of uniform-sized, merchantable potatoes. It is a strong, vigorous grower, and very healthy. Its quality, though not the very best, is good. The Willard, lately originated by C. W. Gleason, of Massachusetts, is a half-early variety. It is enormously productive, of a rich rose color, spotted and splashed with white. The flesh is white. In form and size it closely resembles the Early Goodrich, its parent. It has not been extensively tested, but certainly promises well. The Excelsior is said, by those interested in its sale, to be very productive, and of most excellent quality, retaining its superior flavor all the year round. It is claimed that old potatoes of this variety are better than new ones of most early kinds, thus obviating the necessity of having early sorts. The Excelsior is said to cook very white and mealy; form nearly round, eyes prominent. It has not been much tested out of the neighborhood where it originated. But the potato-eater is yet unborn who can justly find fault with a properly-grown Peach Blow. It is pronounced by many equal or superior to the Mercer in quality, which is not the fact. It is emphatically a late potato; and, though it does not yield as well per acre as some other sorts, it is comparatively healthy; and its quality is such that it always brings a high price in the market. In fact, but few other kinds of late sorts could find sale if enough of this kind were offered to supply the demand. Planted ever so early, it keeps green through the heat of summer, and never matures its tubers until after the fall rains, and then no potato does it more rapidly. Grown on rich argillaceous soil, it will be hollow, coarse flesh, and ill-flavored; but planted on such soil as is recommended, it is about all that could be desired. It is a strong, vigorous grower; and one peculiarity of it is, that insects will not attack vines of this variety if other kinds are within reach. Planted on extremely poor ground, it will, perhaps, yield more bushels of tubers, and those of better quality, than any other variety that could be planted on the same soil. Among all the old or new sorts, perhaps, no potato can be found that deteriorates so little in quality from maturity to maturity again. And, in fine, where only high quality with moderate yield are desired, it has few if any superiors. Many other varieties might be mentioned; but the list given includes about all of much merit. New varieties are constantly arising, clamoring for public favor, many of which are wholly unworthy of general cultivation. One or two varieties, such as are adapted to the grower's locality and market, are preferable to a greater number of sorts grown merely for variety's sake. INFLUENCE OF SOIL ON SEEDLINGS.
