** "From these apartments we were conducted up to a ball-room, decorated in a light, elegant style of painting. The ground was a pale blue, paneled From a Drawing bv Major Andre. with a small gold bead, and in the interior filled with dropping festoons of flowers in their natural eolors. Below the surbase the ground of rose-pink, with drapery festooned in blue. These decorations were heightened by eighty-five mirrors, *** decked with rose-pink silk ribbons and artificial flowers; and in the intermediate spaces were thirty-four branches with wax- lights, ornamented in a similar manner. "On the same floor were four drawing-rooms, with side-boards of refreshments, decorated and lighted in the same style and taste as the ball-room. The ball was opened by the knights and their ladies, and the dances continued till ten o'clock, when the windows were thrown open, and a magnificent bouquet of rockets began the fire-works. These were planned by Captain Montressor, the chief engineer, and consisted of twenty different exhibitions, displayed under his direction with the happiest success, and in the highest style of beauty. Toward the conclusion, the interior part of the triumphal areh was illuminated, amid an uninterrupted flight of rockets and bursting of balloons. The military trophies were on each side. * The chief portions of the decorations were painted by Major André and Captain Oliver Delaney, of New York. The Sienna marble was on canvas, in imitation of scene-painting in theaters. They also painted the scenery for the theater that was established in Philadelphia that winter, the proceeds of which were given to the widows and orphans of their soldiers.--Watson's Annals, ii., 292. ** The costume of the ladies was as follows: those of the Blended Rose a white silk, called a Polonaise, forming a flowing robe, and open in front to the waist; the pink sash six inches wide, and filled with spangles; the shoes and stockings also spangled; the 1 lead-dress more towering than the drawing, and filled with a profusion of pearls and jewels. The vail was spangled, and bordered with silver lace. The ladies of the Burning Mountain wore white sashes edged with black, and black trimmings to white silk Polonaise gowns. There were no ladies of British officers at the entertainment, except Miss Auchmuty, the new bride of Captain Montressor. There were not exceeding fifty American young ladies present; the otters were married, and these were few, lor most of the ladies had left the city on the approach of the British.--Watson's Annals, ii., 293.
