Underneath the body of the barn are the stables, root cellar, calf houses, or any other accommodation which the farm stock may require; but, for the most economical objects, is here cut up into stables. At the ends, _l, l_, are passages for the stock to go into their stalls; and also, on the sides, for the men who attend to them. The main passage through the center double line of stalls is 8 feet wide; and on each side are double stalls, 6-1/2 feet wide. From the two end walls, the cattle passages are 5 feet wide, the partition between the stalls running back in a _slant_, from 5 feet high at the mangers to the floor, at that distance from the walls. The mangers, _j, j_, are 2 feet wide, or may be 2-1/2 feet, by taking an additional six inches out of the rear passage. The passage is, between the mangers, 3 feet wide, to receive the hay from the trap doors in the floor above. [Illustration: UNDER-GROUND PLAN AND YARD.] The most economical plan, for room in tying cattle in their stalls, is to fasten the rope, or chain, whichever is used, (the wooden stanchion, or _stanchel_, as it is called, to open and shut, enclosing the animal by the neck, we do not like,) into a ring, which is secured by a strong staple into the post which sustains the partition, just at the top of the manger, on each side of the stall. This prevents the cattle in the same stall from interfering with each other, while the partition effectually prevents any contact from the animals on each side of it, in the separate stalls. The bottom of the mangers, for grown cattle, should be a foot above the floor, and the top two and a half feet, which makes it deep enough to hold their food; and the whole, both sides and bottom, should be made of two-inch, sound, strong plank, that they may not be broken down. The back sides of the stalls, next the feeding alleys, should be full 3-1/2 feet high; and if the cattle are large, and disposed to climb into their mangers with their fore-feet, as they sometimes do, a pole, of 2-1/2 or 3 inches in diameter, should be secured across the front of the stall, next the cattle, and over the mangers--say 4-1/2 feet above the floor, to keep them out of the manger, and still give them sufficient room for putting their heads between that and the top of the manger, to get their food. Cattle thus secured in double stalls, take up less room, and lie much warmer, than when in single stalls; besides, the expense of fitting them up being much less--an experience of many years has convinced us on this point. The doors for the passage of the cattle in and out of the stables, should be five feet wide, that they may have plenty of room.
