COST OF REFRIGERATION USING NATURAL ICE 



On all three of these farms fairly definite estimates were obtainable 

 of the costs of natural ice refrigeration previous to the installation of 

 electric equipment. Values commonly used on the farm are attached 

 to the various operations to obtain a cost comparison of the two methods. 



Allowances of 20% of the total tonnage of ice stored on Farms No. 

 2 and 4 and 12% on Farm No. 1 are deducted for household use or 

 ]irecooling milk. 



Depreciation and upkeep on ice houses were estimated by the farmers 

 at six to seven per cent on the basis of 14 to 16 year life. While the 

 depreciation of cooling rooms, chilled with ice, is uncertain and governed 

 by drainage and moisture conditions. 20 years is assumed on each farm 

 to be the average useful life. 



Two ice houses were built on Farm No. 2. The first was built by 

 home labor and the second by contract. 



The initial investment, interest and depreciation charges for ice re- 

 frigeration on the three farms are given in Table 10.
