"I was writing to a friend some months ago upon the subject of drainage in this country, and I am pleased to infer from your letter, that our opinions are somewhat similar. The climate of England is much more moist than this, though the amount of rain in many parts of this country, is much greater than the amount of rain there. It drizzles there more than it does here. Owing to the high dew point in England, but a small portion only--that is, comparatively small--of the rain that falls can be evaporated again; consequently, it remains in the soil until it is drained off. Here, on the other hand, the clouds pour it down, and the sun sucks it up right away, so that the perfection of drainage for this country would be the very reverse, almost, of the drainage in England. If, instead of leading the water off into the water-veins and streams of the country, as is there done, we could collect it in pools on the farm, so as to be used in time of drought for irrigation, then your system of drainage would be worth untold wealth. Of course, in low grounds, and all places where the atmosphere does not afford sufficient drainage by evaporation, the English plan will do very well, and much good may be done by a treatise which shall enable owners to reclaim or improve such places." Indeed, the importance of this subject of drainage, seems all at once to have found universal acknowledgement throughout our country, not only from agriculturists, but from philosophers and men of general science. Emerson, whose eagle glance, piercing beyond the sight of other men, recognizes in so-called accidental heroes the "Representative men" of the ages, and in what to others seem but caprices and conventionalisms, the "Traits" of a nation, yet never overlooks the practical and every-day wants of man, in a recent address at Concord, Mass., the place of his residence, thus characteristically alludes to our subject: "Concord is one of the oldest towns in the country--far on now in its third century. The Select-men have once in five years perambulated its bounds, and yet, in this year, a very large quantity of land has been discovered and added to the agricultural land, and without a murmur of complaint from any neighbor. By drainage, we have gone to the subsoil, and we have a Concord under Concord, a Middlesex under Middlesex, and a basement-story of Massachusetts more valuable than all the superstructure. Tiles are political economists. They are so many Young-Americans announcing a better era, and a day of fat things." John H. Klippart, Esq., the learned Secretary of the Ohio Board of Agriculture, expresses his opinion upon the importance of our subject in his own State, in this emphatic language: "The agriculture of Ohio can make no farther marked progress until a good system of under-drainage has been adopted."
