 upon a spring which fills the reservoir and flows off with- 

 out wetting the ground. But as one of the important 

 points about a spring-house is evenness of temperature, 

 a solid heat and cold proof wall is desirable. 



Spring-houses may be used for either shallow or deep 

 setting, but the economy of the latter is too obvious to 

 be disregarded. For instance, to set 400 quarts of milk 

 in shallow pans holding eight quarts each, a trough of 

 more than ninety-six square feet of surface would be re-

 of water lime and sand, in the proportion of one of 

 lime to three of sand. The concrete is laid three inches

 with brick laid in cement, if it is below the surface ; if 

 it is raised above the surface, it maybe built of brick laid 

 in cement and painted inside. For a handsome pool the
