Some of the most prac- tical poultrymen put sills right on the earth and replace them when necessary, finding it cheaper in the long run to do this in buildings of light con- struction than to use heavy sills and pro- tect them to prevent the decay of the wood. Durability has to be considered most in connection with materials which are shorter-lived than wood, and with parts that receive wear. When roofing paper is used for covering, it is economical to use paper of good quality that with proper care may be expected to last from fifteen to twenty years. Cloth is now often preferred to glass for openings, because it is cheaper and admits some air; but cloth or like porous material is so short-lived, when exposed to the weather, that in the long run it may be cheaper to use glass and leave windows partly open, as we do in our dwellings. If cement floors are used they should be substan- tially built; a common mistake is to make them too thin and with an insufficient foundation. Such floors crack and settle and become uneven and very unsatisfactory, and the faults cannot be rem- edied except by taking off the old cement and remaking the floor. WarmtJi is not given such consideration as formerly in the con- struction of houses for adult and weaned birds, but in building in- cubator and brooder houses, or other special buildings which are to.
