^Square room. 



^Enough milk is purchased in addition from nearby farms to represent, it is estimated, 

 a total of 40 cows. 



^Being one of the first machines built by the company it is not equipped with the 

 mercury tube or mercoid automatic control now used. The control in this machine is of 

 the older, breaker-point type. The only trouble reported with the equipment, during the 

 three and one half years of operation, has been with this device. 



*Part of the total surface is not available to radiate cold to the room, because one 

 end of the tank is placed in contact with the wall thereby blocking the radiation from 

 that end. About one-half of the bottom of the tank is similarly blocked by the support- 

 ing rack. ;
