Interior

As the years progressed, interior alterations to the building have been severe and extensive. Originally, marble dados in the vestibule and on stairways dropped to mosaic floors on the ground floor and terrazzo on the upper stories. Stairs had marble treads and ornamental iron railings. There were originally four elevators. Offices ran off a central hallway and were finished in hardwoods.

The ground floor was reserved for banks, but the building's most important space was located on the sixth floor where a large trading room was separated into two pits for the buying and selling of wheat and other grains on the futures market and on a cash basis. The original room, which measured 24.40 X 15.25 meters (80X50 ft.) was later expanded and was lit by the large arched windows on three sides. Ornamentation was kept to the ceiling, as the other wall space was crammed with counters, blackboards, cubicles and the great windows. Changes in the way wheat was bought and sold ultimately spelled doom for the pits, and the entire floor was converted into a Chamber of Commerce dining room.

The building featured its own internal lighting plant with two alternating generators. Steam heat was supplied by three 150 h.p. boilers with automatic coal stokers. The pride of the mechanical system was the ventilator. An immense blower sucked in air from the rooftop, pumped it to the basement for heating, humidified and cleansed it by shooting the air through pipes. Another blower sucked out stale air, giving a complete change of air every twenty minutes.

Over time, all the other floors of the office tower were converted or remodeled to suit new tenants. At present, little remains of the original interior finish.
