 of air around and under the pans. This dairy is a cellar 

 in the rear of a basement, which is used for a churning 

 and wash room. It is entirely below the surface at the

 cemented, the walls are of stone, lathed and plastered, 

 and the ceiling is also lathed and plastered. There is 

 no difficulty in keeping this dairy at a temperature of 

 sixty-two degrees or lower, by having the door and win-

 This secures the requisite evenness and lowness of tem- 

 perature and an advantageous moisture and purity of 

 atmosphere. The best materials for spring-houses are, 

 first, stone ; then, concrete ; and lastly, brick. Wooden 

 spring- houses may be acceptable under such circum- 

 stances as will avoid dampness : for instance, when water 

 is brought from a distant spring in a pipe laid under- 

 ground, and made to discharge in a tank excavated or
