of these rooms to be used either as offices or as laboratories. A narrow ledge is placed against the wall at the height of an ordinary table. Upon this ledge is arranged a system of service supplies usually required in a laboratory. By placing a table against the ledge a convenient laboratory desk is obtained and by removing the table the room is quickly transformed into an office. The work tables and laboratory desks are in most instances constructed with built-up birch wood tops, treated with aniline black. In some of the rooms, however, alberene stone has been used. Many of the lockers in the desks are fitted with wire-glass doors.

T H E DIVISION OF APPLIED CHEMISTRY OCCUpieS the

south end of the building upon the basement and first floor. The equipment of this division provides for work in all lines of industrial chemistry and metallurgy excepting water chemistry and electrochemistry. The large general industrial laboratory in the basenlent has desks for about fifty students in advanced industrial and metallurgical courses. The desks are of a special design with high sanitary base. The west half of the room is used for the installation of larger scale apparatus and machinery for both instruction and research. Supply pipes for gas, compressed air, high pressure steam, vacuum, etc., are conveniently placed, as well as switchboards with outlets for the power circuits. A room for fine balances and an instructor's office and record room are adjacent to this room. METALLURGICAL WORK isprovidedf or in asuite of rooms. For assaying and furnace work of all kinds a Targe room contains permanent installations of coal-, oiland gas-fired muffle and crucible furnaces, a large roasting furnace, besides various experimental furnaces of special design. A fuel storage room is on the east side while oil supply is kept in a large underground reservoir located outside the building and designed for convenient filling from the street. From this tank the oil is forced to a constant-level distributing tank in the fuel room. The pyrometer laboratory located opposite the furnace room is designed for calibration and use of pyrometers, cooling curve work and preparation of metal specimens. Adjacent to this is the metallography laboratory with a pier for supporting two large metallurgical microscopes with cameras. A third microscope will be supported on the firm wall of the vault stack on one side of (he room. A large
