The chemist comes to his aid every year by following out some new hint drawn from nature, and now affirms that this dreary space occupied by the farmer is needless: he will concentrate his kitchen-garden into a box of one or two rods square, will take the roots into his laboratory; the vines and stalks and stems may go sprawling about in the fields outside, he will attend to the roots in his tub, gorge them with food that is good for them. The smaller his garden, the better he can feed it, and the larger the crop. As he nursed his Thanksgiving turkeys on bread and milk, so he will pamper his peaches and grapes on the viands they like best. If they have an appetite for potash, or salt, or iron, or ground bones, or even now and then for a dead hog, he will indulge them. They keep the secret well, and never tell on your table whence they drew their sunset complexion or their delicate flavors. See what the farmer accomplishes by a cartload of tiles: he alters the climate by letting off water which kept the land cold through constant evaporation, and allows the warm rain to bring down into the roots the temperature of the air and of the surface-soil; and he deepens the soil, since the discharge of this standing water allows the roots of his plants to penetrate below the surface to the subsoil, and accelerates the ripening of the crop. The town of Concord is one of the oldest towns in this country, far on now in its third century. The selectmen have once in every five years perambulated the boundaries, and yet, in this very year, a large quantity of land has been discovered and added to the town without a murmur of complaint from any quarter. By drainage we went down to a subsoil we did not know, and have found there is a Concord under old Concord, which we are now getting the best crops from; a Middlesex under Middlesex; and, in fine, that Massachusetts has a basement story more valuable, and that promises to pay a better rent, than all the superstructure. But these tiles have acquired by association a new interest. These tiles are political economists, confuters of Malthus and Ricardo; they are so many Young Americans announcing a better era,--more bread. They drain the land, make it sweet and friable; have made English Chat Moss a garden, and will now do as much for the Dismal Swamp. But beyond this benefit, they are the text of better opinions and better auguries for mankind.
