The first Patriarchs' ball of this season was given last evening at Delmonico's and proved a very successful affair. Four hundred and fifty invitations were issued, but there were not more than about 375 persons present. There was no attempt at elaborate floral decoration of the ballroom, but the floor was covered by new white crash to protect the ladies' dresses from injury, and the ordinary lambrequins and curtains were taken down and replaced by silver damask curtains of rich pattern. For the first time, too, in the history of the Patriarch balls, the ball-room was lighted with a pale, straw-colored light, which is now in vogue in Paris. The room on the Broadway side of the ball-room, better known as the upper supper-room was converted into a salon where tea, chocolate, and ices were served. To furnish a pleasing contrast with the ball-room the salon was lighted with a pink light. The room south of the salon was turned into a conservatory. The halls were also filled with plants and flowers and lighted with pink light. A smaller ball-room was extemporized out of the drawing-room on Fifth-avenue, where music was furnished by a separate orchestra. Supper was served at 12:30 in the restaurant on the ground floor. A very attractive feature of the ball was the number of debutantes present. They were Miss Dresser, Miss Winthrop, Miss Schieffelin, Miss Edith K. Carow, Miss Fannie Swan, Miss Adele Townsend, Miss Emily Hoffman, Miss Witherspoon, Miss Kattie Witherspoon, Miss Grace Potter, Miss Constance Bowden, Miss Florence Clarke, and Miss Gertrude Cheever.
