 The corners are rounded. Shelves 

 The refrigerator is cut into the 

 exposed to the air of the cool 

 entry. Formerly this arrange- 

 ment permitted icing through a 

 door in the rear without enter- 

 ing the house. The sides, top, 

 bottom, and front are exposed to 

 the temperature of the pantry 

 which is heated only in the win- 

 ter indirectly through the kitch- 

 en by the furnace. The oppos- 

 ing temperature is, therefore, 

 somewhat below the average 

 house temperature. The tem- 

 perature in the entry, where the 

 ■compressor is located, is always 

 cool in summer and cold in win- 

 ter. Fig. 6 shows the equip- 

 ment. 



Farm No. 7 



The refrigerator on Farm No. 

 7 is a varnished oak cabinet in- 



around, and the temperature, 

 against which the equii)ment is 

 working, is much lower than on 

 any of the other farms. The 

 results clearly show that the lo- 

 cation of the equipment in a nat- 

 urally cool place reduces the cost 

 of operation considerably, and 

 may compensate for poorer in- 

 sulation. The compressor unit 

 is also favorably located in a 

 very cool basement. 



Farm No. 6 



On Farm No. 6 is a standard, 

 good grade, commercial refriger- 

 ator, having a '% inch varnished 

 oak case, two layers of insulating 

 ]:)aper, a layer of felt, another of 

 mineral wool, and a % inch wood 

 sheathing inside. The compres- 

 sor unit is located in a cool en- 

 try immediately in back of the 

 refrigerator. 



The interior lining is made of 

 compartment, which is zinc lined, 

 are of rust-resisting woven wire, 

 wall of the pantry, and its back is
