It costs no more to cultivate an acre of rich, productive land than an acre of poor, unproductive land; and the pleasure and profit of harvesting a crop that abundantly rewards the husbandman for his care and labor are so overwhelmingly in favor of rich land as to need no comment. Besides, manuring with green crops is not transitory in its effects; the land remembers the generous treatment for many years, and if at times lime or ashes be added to assist decomposition, will continue to yield remunerative crops long after land but once treated with stable manure or guano fails to produce any thing but weeds. The skinning process, the taking off of every thing grown on the soil and returning nothing to it, is ruinous alike to farm and farmer. Thousands of acres can be found in various parts of the country too poor to pay for cultivating without manuring. Of the capabilities of their lands under proper treatment the owners thereof have no idea whatever. Such men say they can not make enough manure on the farm and are too poor to buy. Why not, then, commence plowing under green crops, the only manure within easy reach? If fifty acres can not be turned under the first year, put at least one acre under, which will help feed the rest. Why be contented with thirty bushels of corn per acre, when eighty or one hundred may be had? Why raise eight or twelve bushels of wheat per acre, when forty may as well be had? Why cut but one half-ton of hay per acre, when the laws of nature allow at least three? Why spend precious time digging only one hundred bushels of potatoes per acre, when with proper care and culture three or four hundred may easily be obtained? And, finally, why toil and sweat, and have the poor dumb beasts toil and sweat, cultivating thirty acres for the amount of produce that should grow, may grow, can grow, and has grown on ten acres? The poorest, most forsaken side-hills, cobble-hills, and knolls, if the sand or gravel be of moderate depth, underlaid by a subsoil rather retentive, by turning under green crops grow potatoes of the first quality. If land be so poor that clover will not take, as is sometimes the case, seed to clover with millet very early in the spring, and harrow in with the millet thirty bushels of wood-ashes, or two hundred pounds of guano per acre; then sow the clover-seed one peck per acre; brush it in. If neither ashes nor guano can be obtained at a reasonable price, sow two hundred pounds of gypsum per acre as soon as the bushing is completed. This will not fail in giving the clover a fair foothold on the soil.
