A test of this ice box for six days with an average of 

 200 pounds of ice in the box showed that an average tem- 

 perature of 39° F. was maintained within it, with an 

 average daily consilmption of 40^/^ pounds of ice, while 

 the temperature of the room in which the ice box was 

 kept averaged 74° F. 



When twenty-two gallons of milk, which had been 

 cooled to 45" F., were stored in the box eight hours 

 daily with the other conditions as above, the average 

 daily ice consumption for six days was 49 pounds, and 

 the average temperature of the box 40° F. 



An additional air space could be secured at a small 

 increased expense, and this would not only save ice, 

 but would also make it possible to maintain a somewhat 

 lower temperature than that above indicated.
