Common to all guestrooms is the 18th-century French style of furniture and the use of a distinct color scheme. The guestrooms, unless otherwise noted, are believed to reflect the design of New York decorator Ogden Codman. _Mauve Room._ Most of the furnishings in this room are of French design. In the center of the room is a finely woven Persian dower rug. Pieces on the mantel are of the French Empire period. Each guestroom has a bath and one or more closets. The bathroom accessories always matched the color scheme of the guestroom. _Second Floor Hall._ In 1906, architect Whitney Warren installed the balustrade which now overlooks the reception hall. [Illustration: _Second floor hall._] In the second floor hall are three 18th-century Flemish tapestries, two Italian fringed and embroidered hangings draped over the balustrade, and two sets of matched high-backed chairs in walnut—one set of six chairs, one of four. A teakwood cabinet is of Chinese design. _Red Rooms._ These rooms open onto the second floor hall and are connected by a doorway to form a two-room suite. Furnishings are in the French style. A frieze on a Greek subject embellishes the 18th-century English Georgian mantel in the larger room. _South Foyer._ This leads to the master bedrooms. French doors can be closed to separate this wing from the rest of the second floor. In the foyer are paintings by Kellar-Reutlingen and Firman-Girard. _Frederick Vanderbilt’s Room._ This room has carved woodwork of Circassian walnut. The bed and dresser were designed as part of the woodwork and were installed by Norcross Brothers. The room was designed by Georges A. Glaenzer. The walls and doors are covered with 17th-century Flemish tapestry. Hand-painted designs on the silk lampshades match those on the Chinese bases. The fireplace has a large carved mantel. On the floors are dark-red rugs made in India. [Illustration: _Frederick Vanderbilt’s room.
