Fig. 41.—SPRING-HOUSE FOR MILK. suddenly when several twenty-quart pails of milk are put into the pool, the outlet is made of three-inch glazed drain tile, covered with wire gauze as a protection. The drain discharges into a stream close behind the spring- house. To cool 200 quarts of milk from seventy-five or eighty degrees down to fifty-five, requires either consider- able time or a good flow of cold water. With a flow of two quarts per minute of water at a temperature of fifty-five degrees, and an air temperature of eighty de- grees, four hours are required to reduce the milk to the temperature of sixty degrees, and the temperature of the milk cannot be reduced as low as that of the water unless the pool is protected by a covering from the air. It may thus be found advisable to provide falling doors io cover the tank when the water supply is not more.
