The stable doors, (_j_, _j_,) are six in number. Small windows, for ventilation, should be cut in the rear of the stalls, as marked, and for throwing out the manure, with sliding board shutters. This completes the barn accommodation--giving twenty-eight double stalls, where fifty-six grown cattle may be tied up, with rooms for twenty to thirty calves in the end stables. If a larger stock is kept, young cattle may be tied up, with their heads to the bays, on the main floor, beyond the thrashing floor, which we practice. This will hold forty young cattle. The manure is taken out on a wheel-barrow, and no injury done to the floor. They will soon eat out a place where their forage can be put, and do no injury beyond that to the hay in the bays, as it is too closely packed for them to draw it out any farther. In this way we can accommodate more than a hundred head of cattle, of assorted ages. The hay in the bays may drop three feet below the level of the main floor, by placing a tier of rough timbers and poles across them, to keep it from the ground, and many tons of additional storage be thus provided. We have often stored one hundred and fifty tons of hay in this barn; and it will hold even more, if thoroughly packed, and the movable girts over the main floor be used, as described in Design I. The chief advantages in a barn of this plan are, the exceeding convenience of getting the forage to the stock. When the barn is full, and feeding is first commenced, with a hay knife, we commence on each side next the stables, on the top of the bays, cut a _well_ down to the alley way in front of the mangers, which is left open up to the stable roof. This opens a passage for the hay to be thrown into the alleys, and in a short time it is so fed out on each side, that, the sides of the main barn being open to them, the hay can be thrown along their whole distance, and fed to the cattle as wanted; and so at the rear end stables, in the five-foot alley adjoining them. If a root cellar be required, it may be made under the front part of the main floor, and a trap-door lead to it. For a milk dairy, this arrangement is an admirable one--we so used it for four years; or for stall-feeding, it is equally convenient. One man will do more work, so far as feeding is concerned, in this barn, than two can do in one of almost any other arrangement; and the yards outside may be divided into five separate inclosures, with but little expense, and still be large enough for the cattle that may want to use them. It matters not what kind of stock may be kept in this barn; it is convenient for all alike. Even sheep may be accommodated in it with convenience. But low, open sheds, inclosed by a yard, are better for them; with storage for hay overhead, and racks and troughs beneath.
