East and west marble stairways lead from the main floor of the Senate wing to the ground floor. There are also two elevators, and two private stairways, whose railings are artistically wrought in bronze. The post-office of the-Senate is now situated in the northeast corner. Over the entrance to this room, which was formerly occupied by the Committee on Patents, is pictured Robert Fulton upon a balcony overlooking the Hudson ; in the distance is his pioneer steamboat, the Clermont, and beyond are the Palisades. The Senate restaurant occupies the space east of the main corridor of the Capitol, between the eastern and middle corridors of the wing. Both the Senate and House restaurants are open to the public, as well as to Senators and Members.
