The capacity of the refrigerator in each case satisfied the require- 

 ments of the farm household. The refrigerator on Farm No. 1, having 

 5.5 cubic feet of food storage space, is considered the minimum size, 

 and the refrigerator on Farm No. 2, the maximum size to be recom- 

 mended. The latter is too large for ordinary use, but would be a use- 

 ful size for a farm that held reasonable quantities of market produce 

 for opportune sale, or for a farm with a roadside or at-the-door bus- 

 iness. 



Two refrigerators (Nos. 1 and 6) operated on a 12 months basis; 

 four operated only in warm weather. April or May was the usual time 

 for starting in the spring, and December was the usual closing month 

 in the Fall.
