The hostess made it a point to blend the color of the flowers, the cloth, and the china. If yellow flowers were being used, the lace cloth would have a yellow undercover, the service would be gold-plated, and the china would be white with a gold stripe.

GRAND STAIRWAY

On the wall opposite the foot of the stairway is an 18th-century Flemish tapestry. The floor in the lower-stair hall is old Italian marble. A chair and marble fernery are Italian, and a large Chinese bowl of the Ming Dynasty is about 500 years old. Italian busts and statues occupy niches along the way. At one of the landings is a painting by the French artist, Adrien Moreau. An early 18th-century Beauvais tapestry hangs on the second-floor wall.

SECOND FLOOR

North Foyer.

On a Louis XVI table stands an incense burner fashioned of marble and cloisonne. Overhead is a chandelier of beaded crystal; one of similar design is in the south foyer. Hanging here are original paintings by the 19th-century artists, Schreyer, Bougereau, and Villegas. Frederick Vanderbilt was more noted for the fine tapestries he collected than for outstanding paintings.

Blue Room.

This is the largest of the guest rooms. Mrs. James Van Alen, the niece of Mrs. Vanderbilt who donated the mansion to the Federal Government, used this room during her visits to the Vanderbilts. The windows of this room command a splendid view of the Hudson and the mountains beyond. A white onyx French clock and companion pieces adorn the mantel, and a rare old (Ghiordes) prayer rug is spread before the fireplace.
