Once each day, except bathing days, the engine was operated from 
a half hour to one hour to charge the air tank with air at 100 pounds 
pressure. On bathing days it was necessary to recharge the tank 
immediately before the bathing began. With the tank charged a 
supply of water was always available at any of the faucets, as the 
opening of a faucet automatically set the pump to work. 
Four shower fixtures were provided in the bath tent, and water was 
heated for bathing by two heaters coupled in tandem, having a com- 
bined water-heating surface of 880 square inches, and a grate area 
of 127 square inches. A 40-gallon tank was installed for the storage 
of hot water. 
Table 7 shows the results of a test of the efficiency of the hot-water 
system.
