The pinnibing arrmxgements are exceptionally complete. Enameled-iron sinks with 

 hot and cold water are installed in all laboratory rooms and where needed in the shop rooms 

 and elsewhere. The lavatories are finished in white marble, with complete appointments 

 and shower baths. All fixtures are back-vented. A gas connection is in general supplied 

 to one wall-bracket in each room for use when, for any reason, there is an interruption in 

 the electric power supply. All exposed water pipes in the basement and sub-basement are 

 covered with five-eighths inch felt covering wrapped in a double thickness of canvas and 

 bound with brass bands. 



No special provisions were made for protection against lightning ; the copper sheathing 

 surrounding the edge of the observation deck, and the numerous vent pipes, are deemed 

 sufficient protection.

 coal-gas not being available, it was necessary to install a gasoline gas-generator in the fur- 

 nace-room, with an underground gasoline reservoir placed outside. This room also con- 

 tains the hot-water heater of 150 gallons capacity and the hot-water storage 100-gallon 

 tank for supplying hot water to all sinks and lavatories. A stationary vacuum-cleaner 

 and motor, with outlets in various parts of the building, is mounted in the first vestibule 

 to the large constant-temperature room. The latter room. No. 001, is surrounded by earth 

 on all sides except for the space required by the entrance vestibules, of which there are 3.
