Register and official announcement . Fourth Fifth Floor. The central portion of the building is carried up another storyand is reached by two flights of stairs leading into a hall or gal- 87 lery (Nos. 97-98) 44 x 80 feet and with a dome light 12 x 40.

The boiler-room, where the steam heating apparatus is located,is arched over with brick and iron girders, making the room abso-lutely fire proof.

The two large boilersare of 110 horse-power each. They are 6x17 feet in size, with 16feet tubes, 3i inches in diameter. The boilers stand side by side,and are connected at the top by a drum.
