COOLING AND AERATION 



37 



As might be expected, by forcing the ice water from 

 the cooler back into the ice water storage, a considerable 

 saving is effected, not only of ice and water, but of time 

 as well. Proof of these advantages is brought out by the 

 results recorded in the following table, which shows the 

 work of the cooler with and without the ice water pump. 

 When no pump was used, 'ordinary well water was 

 sprayed over fiiiely crushed ice in the can shown at the 

 right, and the discharge was allowed to run into the 

 drain.
