This is a variety of cress, of quick growth, used as lettuce. On a rich, finely-pulverized soil, sow the seeds in drills, fifteen inches apart, and cover very lightly. Sow thick and water in dry weather. For use, cut the tops while they are very tender. A second crop will grow, but inferior to the first. The water-cress, growing spontaneously by rills and springs, is a kind of wild peppergrass, and is by some persons more esteemed than the garden variety. We prefer early lettuce to cresses or peppergrass, and see no reason for their cultivation, but their rapid growth. PLOWING. This is one of the most important matters in soil-culture. When, how, and how much, shall we plow? are the three questions involving the whole. When should plowing be done? As it respects wet or dry, plow sandy or gravelly land whenever you are ready. It will neither be hard when dry, nor injured by being plowed when very wet. Good loams may be plowed at all times except when excessively wet. Clays can only be worked profitably when neither excessively wet or dry. Plowing land in a warm rain is almost equal to a coat of manure. Plowing in a light snow in the spring will injure it the whole season. We have noticed a marked difference in corn growing but a rod apart, on land where snow was plowed in, and the other plowed two or three days later, after the snow was gone; this difference was noticeable in the rows throughout the entire field. Spring or fall plowing is a question that has been much discussed. Sod-land is better plowed in the fall. The action of winter rains and frosts on the turf is beneficial. The same is true of land trenched deep, where much of the hard, poor subsoil is brought to the surface: it is benefited by winter exposure. Other cultivated fields are injured by fall-plowing, unless it be very early. All stubble-land is much benefited by being plowed as soon as the grain is taken off. The weeds and stubble, plowed under, will be decomposed by the warm weather and rains, and benefit the soil almost as much as an ordinary coat of manure. Plowed late, such action does not take place, and the surface is injured by winter-exposure: hence, do all the _early_ fall-plowing possible, but plow nothing _late_ in the fall but sod-land.
