The plan is shown by the diagram (figure 41),in which a section across the house and pool is house is twelve feet square. The pool was sunkuntil a bubbling spring was reached, and the bottom waspared with flat stones loosely placed, the water risingthrough the spaces between the stones until it flowed outof a pipe at the top, shown at b, leaving a depth ofeighteen inches of water in the pool.

Thedrain discharges into a stream close behind the spring-house. To cool 200 quarts of milk from seventy-five or eightydegrees down to fifty-five, requires either consider-able time or a good flow of cold water. With a flowof two quarts per minute of water at a temperature offifty-five degrees, and an air temperature of eighty de-grees, four hours are required to reduce the milk to thetemperature of sixty degrees, aod the temperature ofthe milk cannot be reduced as low as that of the waterunless the pool is protected by a covering from the may thus be found advisable to provide falling door3to cover the tank when the water supply is not more THE CASE OF MILK. 249 than two quarts in a minute, which is equal to a flow,witho
