We here present the elevation of a poultry-house in perspective, to show the _principle_ which we would adopt in its construction, and which may be extended to any required length, and to which may be added any given area of ground, or yard-room, which the circumstances of the proprietor may devote to it. It is, as will be seen, of a most rustic appearance, and built as cheaply, yet thoroughly, as the subject may require. Its length, we will say, is 20 feet, its breadth 16, and its height 10 feet, made of posts set into the ground--for we do not like sills, and floors of wood, because rats are apt to burrow under them, which are their worst enemies--and boarded up, either inside or outside, as in the case of the ice-house previously described, though not double. Plates are laid on these posts, to connect them firmly together; and the rafters rest on the plates, as usual. The chamber floor is 9 feet high, above the ground, and may be used either for laying purposes by the fowls, or reserved as a storage-room for their feed. The roof is broadly drawn over the body of the building, to shelter it, and through the point of the roof, in the center, is a ventilator, with a covered top, and a vane significant of its purpose. It is also sufficiently lighted, with glass windows, into which our draughtsman has put the diamond-paned glass, contrary to our notions; but, as he had, no doubt, an eye to the "picturesque," we let it pass, only remarking, that if we were building the house on our own account, there should be no such nonsense about it. The front windows are large, to attract the warmth of the winter's sun. A section of picket fence is also attached, and trees in the rear--both of which are necessary to a complete establishment; the first, to secure the poultry in the contiguous yards, and the trees to give them shade, and even roosting-places, if they prefer such lodgings in warm weather--for which we consider them eminently wholesome. The wooden floor is dispensed with, as was remarked, to keep rid of the vermin. If the ground be gravelly, or sandy, it will be sufficiently dry. If a heavy or damp soil be used, it should be under-drained, which will effectually dry it, and be better for the fowls than a floor of either wood, brick, or stone. Doors of sufficient size can be made on the yard sides of the house, near the ground, for the poultry to enter either the living or roosting apartments, at pleasure, and hung with butts on the upper side, to be closed when necessary.
