Warmth is the most important point of all. Fowls that roost in cold houses and exposed places require more food and produce fewer eggs; and pullets which are usually forward in laying will not easily be induced to do so in severe weather if their house is not kept warm. It is a great advantage when the house backs a fire-place or stable. A gentleman told Mr. Baily that he "had been very successful in raising early chickens in the north of Scotland, and he attributed much of it to the following arrangements. He had always from twenty to thirty oxen or other cattle fattening in a long building; he made his poultry-house to join this, and had ventilators and openings made in the partition, so that the heat of the cattle-shed passed into the fowl-house. Little good has resulted from the use of stoves, or hot-water pipes, for poultry; but by skilfully taking advantage of every circumstance like that above mentioned, and by consulting aspect and position, many valuable helps are obtained." A house built of wood in the north of England and Scotland must be lined, unless artificially warmed. Felt is the best material, as its strong smell of tar will keep away most insects. Matting is frequently used, and will make the house sufficiently warm, but it harbours vermin, and therefore, if used, should be only slightly fastened to the walls, so that it can be often taken down and well beaten, and, if necessary, fumigated. Various materials are recommended for the flooring. Boards are warm, but they soon become foul. Beaten earth, with loose dust scattered over it some inches deep, is excellent for the feet of the birds, but is a harbour for the minute vermin which are often so troublesome, and even destructive, to domestic fowls. Mowbray recommends a floor of "well-rammed chalk or earth, that its surface, being smooth, may present no impediment to being swept perfectly clean." Chalk laid on dry coal-ashes to absorb the moisture is excellent. A mixture of cow-dung and water, about the consistency of paint, put on the surface of the floor, no thicker than paint, gives it a hard surface which will bear sweeping down. It is used by the natives of India, not only for the floors, but often for the walls of their houses, and is supposed to be healthy in its application, and to keep away vermin. Miss Watts says: "Dig out the floor to about a foot deep, and fill in with burnt clay, like that used extensively on railways, the strong gravel which is called 'metal' in road-making, or any loose dry material of the kind. Let this be well rammed down, and then lay over it, with a bricklayer's trowel, a flooring of a compost of cinder-ashes, gravel, quick-lime, and water. This flooring is without the objections due to those which are cold and damp, and those which imbibe foul moisture. Stone is too cold for a flooring; beaten earth or wood becomes foul when the place is inhabited by living animals; and a flooring of bricks possesses both
