Except in the neighborhood of large cities, “high farming” may not pay, owing to the fact that we have so much land. But whether this is so or not, there can be no doubt that the only profitable system of farming is to raise large crops on such land as we cultivate. High farming gives us large crops, and _many of them_. At present, while we have so much land in proportion to population, we must, perhaps, be content with large crops of grain, and few of them. We must adopt the slower but less expensive means of enriching our land from natural sources, rather than the quicker, more artificial, and costly means adopted by many farmers in England, and by market gardeners, seed-growers, and nurserymen in this country. Labor is so high that we can not afford to raise a small crop. If we sow but half the number of acres, and double the yield, we should quadruple our profits. I have made up my mind to let the land lie in clover three years, instead of two. This will lessen the number of acres under cultivation, and enable us to bestow more care in plowing and cleaning it. And the land will be richer, and produce better crops. The atmosphere is capable of supplying a certain quantity of ammonia to the soil in rains and dews every year, and by giving the wheat crop a three years supply instead of two years, we gain so much. Plaster the clover, top-dress it in the fall, if you have the manure, and stimulate its growth in every way possible, and consume all the clover on the land, or in the barn-yard. Do not sell a single ton; let not a weed grow, and the land will certainly improve.
