 In considering the cooling effect of ice it must be re- 

 membered that the low temjjerature is only gained by 

 the expenditure of the ice, aud that it is a question if 

 it is better to make use of an ice-house constructed in 

 the most economical manner, or to so use the ice as to 

 procure a continuous low temperature with the certain 

 large waste of ice that would be inevitable. There 

 may be some cases, however, in which the ease of op- 

 erating a cooling apparatus may be more convenient, 

 although it may consume more ice, than to handle 

 blocks of ice in carrying them from the ice-house to the

creamery for use. Where ice is abundant this view of 

 the question may be reasonably considered. A point 

 that bears strongly upon it is that the ice may be stored 

 in the winter when the labor may cost comparatively 

 nothing, because there is plenty of time and opportunity 

 for the work, aud in summer time is more valuable and 

 business presses closely upon opportunities, so that the 

 handling of tlie ice in the summer would, in fact, be 

 more irksome and costly than the waste involved. For 

 to open the ice-house, take out the blocks required, carry
