There are so many wrong ways to do a thing to but one right one that there is no reason in the impatience too often evinced with those who contrive to swallow the truth wrong end foremost, and thereupon insist that it won't do. For instance: A farmer hears something said of deep plowing, and, without any clear understanding of or firm faith in it, resolves to give it a trial. So he buys a great plow, makes up a strong team, and proceeds to turn up a field hitherto plowed but six inches to a depth of a foot: in other words, to bury its soil under six inches of cold, sterile clay, sand, or gravel. On this, he plants or sows grain, and is lucky indeed if he realizes half a crop. Hereupon, he reports to his neighbors that Deep Plowing is a humbug, as he suspected all along; but now he knows, for he has tried it. There are several other wrong ways, which I will hurry over, in order to set forth that which I regard as the right one. Here is a middling farmer of the old school, who walks carefully in the footsteps of his respected grandfather, but with inferior success, because sixty annual harvests, though not particularly luxuriant, have partially exhausted the productive capacity of the acres he inherited. He now garners from fifteen to thirty bushels per acre of Corn, from ten to twenty of Wheat, from fifteen to twenty of Rye, from twenty to thirty of Oats, and from a tun to a tun and a half of Hay, as the season proves more or less propitious, and just contrives to draw from his sixty to one hundred acres a decent subsistence for his family; plowing, as his father and grandfather did, to a depth of five to seven inches: What can Deep Plowing do for _him_? I answer--By itself, nothing whatever. If in every other respect he is to persist in doing just as his father and his grandfather did, I doubt the expediency of doubling the depth of his furrows. True, the worst effects of the change would be realized at the outset, and I feel confident that his six inches of subsoil, having been made to change places with that which formerly rested upon it, must gradually be wrought upon by air, and rain, and frost, until converted into a tolerably productive soil, through which the roots of most plants would easily and speedily make their way down to the richer stratum which, originally surface, has been transposed into subsoil. But this exchange of positions between the original surface and subsoil is not what I mean by Deep Plowing, nor anything like it. What I _do_ mean is this:
