Thus far my English friend. Who will this year try a patch of Peas on a plat made rich and mellow for a depth of at least two feet, and frequently moistened in Summer by some rude kind of irrigation?
The fierceness of our Summer suns, when not counteracted by frequent showers, shortens deplorably the productiveness of many Vegetables and Berries. Our Strawberries bear well, but too briefly; our Peas wither up and cease to blossom after they have been two or three weeks plump enough to pick. Our Raspberries, Blackberries, etc., fruit well, but are out of bearing too soon after they begin to yield their treasures. I am confident that this need not be. With a deep, rich soil, kept moistened by a periodical flow of water, there need not and should not be any such haste to give over blooming and bearing. The fruit is Nature's attestation of the geniality of the season, the richness and abundance of the elements inhering in the soil or supplied to it by the water. Double the supply of these, and sterility should be postponed to a far later day than that in which it is now inaugurated.

PLOWING—GOOD AND BAD.
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:
Having thoroughly underdrained a field, so that water will not stand upon any part of its surface, no matter how much may there be deposited, the next step in order is to increase the depth of the soil. To this end, procure a regular sub-soil plow of the most approved pattern, attach to it a strong team, and let it follow the breaking-plow in its furrow, lifting and pulverizing the sub-soil to a depth of not less than six inches, but leaving it in position exactly where it was. The surface-plow turns the next furrow upon this loosened sub-soil, and so on till the whole field is thus pulverized to a depth of not less than twelve inches, or, better still, fifteen. Now, please remember that you have twice as much soil per acre to fertilize as there was before; hence, that it consequently requires twice as much manure, and you will have laid a good foundation for increased crops. I do not say that all the additional outlay will be returned to you in the increase of your next crop, for I do not believe anything of the sort; but I do believe that this crop will be considerably larger for this generous treatment, especially if the season prove remarkably dry or uncommonly wet; and that you will have insured better crops in the years to come, including heavier grass, after that field shall once more be laid down; and that, in case of the planting of that field to fruit or other trees, they will grow faster, resist disease better, and thrive longer, than if the soil were still plowed as of old. (I shall insist hereafter on the advantage and importance of subsoiling orchards.)
