The intelligent farmer, who grows large crops for market, will always so arrange as to have a clover-sod on dry land in high condition each year for potatoes. It is said by many, in regard to swine, that "the breed is in the trough;" though this is certainly untrue to a certain extent, yet it is undeniable that in potato-growing success or failure is in the character of soil chosen for their production. Why clover, or clover and buckwheat lands, are so strongly urged is, such lands have in them just what the tubers need for their best and healthiest development; the soil is rendered so rich, light, and porous, and so free from weeds, that the cultivation of such land is rather a pleasure than otherwise, and at the close of the season the tangible profits in dollars and cents are highly gratifying. VARIETIES. From the fact that the United States produce about 109,000,000 bushels of potatoes annually, it might be supposed a great many varieties would be cultivated. Such, however, is not the fact. Of the varieties extant, comparatively few are grown extensively. Every grower's observation has established the fact that for quality the early varieties are inferior to the late ones. The Early June is very early, but its quality is quite indifferent. The Cherry Blow is early, attains good size, and yields rather well. In quality it is poor. The Early Kidney, as to quality, is good, but will not yield enough to pay for cultivation. The Cowhorn, said to be the Mexican yam, is quite early, of first quality, but yields very poorly. The Michigan White Sprout is early, rather productive, and good. Jackson White is in quality quite good, is early, and a favorite in some places. The Monitor is rather early, yields large crops; but as its quality is below par, it brings a low price in market. Philbrick's Early White is one of the whitest-skinned and whitest-fleshed potatoes known. It is about as early as Early Goodrich, is quite productive, and grows to a large size, with but few small ones to the hill. Its quality is excellent. It has not yet been extensively tested. The Early Rose is said to be very early, of excellent quality, and to yield extremely well. It has, however, not been very widely tested. Perhaps for earliness and satisfactory product, the Early Goodrich has no superior. It is of fair quality, and though some seasons it does not yield as well as others, yet, all things considered, it is a desirable variety. The old Neshannock, or Mercer, is among the latest of the early varieties. As to quality, it is the standard of excellence of the whole potato family. But it yields rather poorly, and its liability to rot, except on soils especially fitted for it, has so discouraged growers that its cultivation in many sections is abandoned. On rather poor, sandy soil, manured in the hill with wood-ashes, common salt, and plaster only, it will produce in ordinary seasons two hundred bushels per acre of sound, merchantable tubers, that
