Most barns in New England are constructed with good substantial cellars, from six to nine feet deep, with solid walls of stone. They serve a three-fold purpose; of keeping manure, thrown down from the cattle and horse stalls above; of preserving turnips, mangolds, and other vegetables for the stock; and of storing carts, wagons, and other farm implements. Usually, the cellar is divided by stone, brick, or wood partitions, into apartments, devoted to each of the purposes named. The cellar for manure should not be wet enough to have water flow away from it, nor dry enough to have it leach. For the other purposes, a dry cellar is desirable. Perhaps the details of the drainage of a barn cellar on our own premises, may give our views of the best mode of drainage, both for a manure cellar, and for a root and implement cellar. The barn was built in 1849, on a site sloping slightly to the south. In excavating for the wall, at about seven feet below the height fixed for the sills, we came upon a soft, blue clay, so nearly fluid that a ten-foot pole was easily thrust down out of sight, perpendicularly, into it! Here was a dilemma! How could a heavy wall and building stand on that foundation? A skillful engineer was consulted, who had seen heavy brick blocks built in just such places, and who pronounced this a very simple case to manage. "If," said he, "the mud cannot get up, the wall resting on it cannot settle down." Upon this idea, by his advice, we laid our wall, on thick plank, on the clay, so as to get an even bearing, and drove down, against the face of the wall, edge to edge, two-inch plank to the depth of about three feet, leaving them a foot above the bottom of the wall. Against this, we rammed coarse gravel very hard, and left the bottom of the cellar one foot above the bottom of the wall, so that the weight might counterbalance the pressure of the wall and building. The building has been in constant use, and appears not to have settled a single inch. The cellar was first used only for manure, and for keeping swine. It was quite wet, and grew more and more so every year, as the water found passages into it, till it was found that its use must be abandoned, or an amphibious race of pigs procured. It was known, that the most of the water entered at the north corner of the building, borne up by the clay which comes to within three feet of the natural surface; and, as it would be ruinous to the manure to leach it, by drawing a large quantity of water through it into drains, in the usual mode of draining, it was concluded to cut off the water on the outside of the building, and before it reached the cellar. Accordingly, a drain was started at the river, some twenty rods below, and carried up to the barn, and then eight feet deep around two sides of it, by the north corner, where most water came in.
