The solid construction is tight, but cold. Numbers 1, 2 and 3 in Fig. 560, show the com- parative temperatures outside and inside a house at different times of the day, and the effect that each type of wall will have on the warmth and dryness of the house un- der varying con- ditions. When a house is tight and insulated, and the air is not allowed to change freely, it will be warmer during the cold nights inside than it is outside the house. When the sunshine, the following day, warms the air outside, frequently it is colder inside than it is outside the house. When warm air enters it picks up the moisture. The moisture-laden air comes in contact with the cold walls, which condense the moisture, and the house is said to sweat. If the walls are sufficiently cold, the moisture freezes and the walls are covered with frost. In order to secure reasonable warmth and dryness in a hen-house, the walls should be tight on all sides, including roof and floor, except the south, which may be compara- tively loose. This provides a quiet inter- change of air without draft. Roof of the poultry-house. The style of roof influences to a large extent the cost and efficiency of a poultry- house.
