ICE-HOUSES FOR THE DAIRY FARM. 15 



A permanent and neat building is preferable, but 

 a dairy farmer should not neglect a supply of ice 

 because he has no suitable building. 



Less sawdust is required on the ice if the walls of 

 the building be packed with six or eight inches of 

 sawdust ; but this plan tends to hold moisture in the 

 walls, and causes the building to decay in a short 

 time. 



For a herd of twenty-five cows a dairyman should 

 provide from fifty to seventy five tons of ice. This 

 would require about 2,000 cubic feet of space, or a 

 room ten by ten and twenty feet high. 



A cubic foot of water weighs about sixty-two and 

 one-half pounds. One cubic foot of ice weighs about 

 fifty-seven and one-half pounds. Water, in freezing, 

 expands about eight and one-half per cent. An ice- 

 house may be filled from a small pond near the farm 

 if the water be clean. By knowing the cubic content 

 of the pond a calculation may be made as to the 

 amount of ice which may be secured from it by 

 noting the foregoing points relative to water and ice. 

 An ice-house may also be filled by running water into 

 it and allowing the water to freeze in a solid body.
