The Ihpetonga Club's ball, at the Art Association Assembly Rooms last night, was the society event of the season in Brooklyn. No entertainment was ever before given here which was better planned or more brilliantly carried out. It was a private affair: in fact, just such an entertainment as the Patriarchs' ball, of New York. It was an event that had long been anticipated. Everything worked favorably for the managers: even the weather indulged in an agreeable change at 11 o'clock from a mild to a cold crisp air, just such a night as merry dancers would vote for.

The ball was given by fifty-eight of the leading society men in Brooklyn, mostly of the Heights, who subscribed to a common fund and who, on the score of the subscription, invited five of their friends to the entertainment.

The subscribers to the ball were Tunis G. Bergen, Frederick P. Bellamy, James C. Bergen, Edwin Beers, Thomas B. Bowring, Samuel W. Boocock, Clarence W. Bowen, Henry D. Brookman, Amory S. Carhart, Henry A. Caesar, Simeon B. Chittenden, Henry B. Cromwell, Henry J. Cullen, Jr., Frederic Cromwell, Carl H. De Silver, Cortlandt P. Dixon, Watson B. Cickerman, Abbott L. Dow, Latham A.

To Mr. Arthur M. Hatch last night's ball meant a great deal: it was the brilliant and successful fulfillment of his plans. He more than any one else had to do with the management of the affair and many of the artistic effects in the decorations were original ideas evolved from his mind.

Preparations for the ball were begun several weeks ago. The decorators had possession of the rooms from the day following the Charity assembly on Monday evening of last week until late yesterday afternoon, when they turned them over to the committee. With the exception of the dancing hall green was the predominating color. The large lobby was heavily carpeted, and as the guests entered from the street they passed through a heavy fencing of palms, pine and holly trees and ferns. The decorations were continued up the broad stairs and on the landing.

The ladies' cloak rooms were at the extreme end of the lobby. Here ladies' maids were found in attendance to assist the guests in uncloaking and preparing for their appearance in the ball room. These rooms were screened and decorated by draperies and abundantly supplied with mirrors and dressing cases. So carefully had everything been prearranged that there was no confusion or misunderstanding in getting what was one's own.

The Ihpetonga's ball room decorations have always been elaborate, but this year they were richer and grander than ever before and the superb effect was a genuine surprise to everybody. The decorations of the room formed an admirable and effective background for the beautiful and varied costumes worn by the ladies. The ball room resembled a large private drawing room, the wall being hung with Aubusson tapestries, representing scenes from modern French art. Indeed, some of these pieces were worthy of description from the pen of an art connoisseur. The animated Gypsy scene on the east wall was especially worthy of mention. The walls were covered with old gold stuff and the deep frieze was of soft cream colored material and enriched by large fan shaped frames in delicate pink colored material, placed at equal distances about the room. Pink and white cords and tasssels hung in graceful droop from fan to fan, and between were large palm leaves. The large chandeliers which illuminated the room were trimmed with branches of holly and covered with pink tarlatan to subdue the light, so that the ordinary glare was softened and came down upon the guests with delightful effect. The floor was heavily crashed. For those people who went to the ball to look on rather than to dance provision had been made by placing two rows of chairs on either side of the room. At the extreme end of the ball room and on the side several large mirrors were introduced with fine result. The wall above was inlaid with designs in palms and roses. At each corner of the room were raised platforms trimmed with draperies of damask and white and pink azaleas, lilies and other flowers. On these were Stub's Orchestra and the Mandolin Orchestra. The bands played alternately through the evening, and there was no five minutes without music. A bank of azaleas were arranged along between the platforms and the mirrors were framed in holly, while on the floor in front was a bank of delicious flowers.

It was 10 o'clock before the guests began to arrive in large numbers, and at 10:45 the lobby, the stairs and the ballroom were full of people and the scene became animated, the low strains of an entrancing waltz floated out from the corners over the large crash covered room and the feet of many dancers were set flying. As the guests entered the ballroom the names were announced by a man who makes that sort of thing his business. The guests were then received by Mrs. Henry D. Brookman, Mrs. A. Augustus Low and Mrs. Thomas E. Stillman, the lady patronesses, who took their station at the left of the entrance to the ballroom and curtseyed as the guests entered. From 11 o'clock there was almost continuous dancing. By midnight the ball was at its height. It seemed as though all the married belles and debutantes were there and with their superb dresses and brilliant jewels and the rich costumes of the matrons a scene was presented which will not be soon forgotten.

Just after midnight the doors leading to the supper room were thrown open and behold! a miniature forest was presented to the view of the gay dancers. Fir trees and pines surrounded the entire room, while festoons and roping of laurel hung from the ceiling. The green was touched here and there by roses and bright flowers, and balls of roses were suspended from the chandeliers. The small supper tables were beautifully arranged and silver candelabras and white candles made a pretty scene. Pinard served the supper. Plates were laid for 300. The table for the committee and patronesses occupied the center of the room and was especially attractive. It was laid with twelve plates and was adorned with floral pieces. Around this table sat Mr. Hatch, Mrs. Washington A. Roebling, Mrs. Wilmerding, Mr. Amory S. Carhart, Mr. A. Augustus Low, Mr. J. Jay Pierrepont, Mr. William Cary Sanger, Mr. William C. Sheldon, Jr.; Mrs. Henry D. Brookman, Mrs. A. Augustus Low and Mrs. Thomas E. Stillman.

The supper was a delightful feature of the evening. The mandolin orchestra played during the whole time. Pinard's men served everybody satisfactorily and promptly, and there was no undue haste or confusion. The supper lasted just one hour.

The cotillion which followed the supper was watched with interest. There was some waltzing before it and general promenading for a time, and then the pretty dance was formed. Mr. Arthur M. Hatch led it, dancing with Miss Jessie Stillman, a charming and popular debutante of the season.

The small room dividing the supper room and ballroom was richly decorated in turkey red, with Bagdad curtains and Oriental tapestries, while large, casy divans invited a quiet tete a tete. Another small room off from the ballroom was exquisitely decorated in blue and pink: the floor was covered with heavy rugs, and plush covered chairs and couches were here provided for the guests.

Miss Stillman's gown was one of white tulle, garniture with red, and she wore red berries.

Mrs. Washington A. Roebling wore a dress of white satin brocade and point lace. Her ornaments were diamonds.

Mrs. John Notman danced in a pretty dress of pink tulle, with garniture of gold.

Miss Poor, a society belle of Baltimore, wore a gray tulle gown.

Mrs. William C. Sheldon wore a gown of yellow tulle and silver trimming.

Mrs. A. Augustus Low wore a pink satin brocade dress and carried a bouquet of lilies of the valley and orchids.

Mrs. Henry D. Brookman's gown was brocade and point lace. She wore diamonds.

Mrs. Thomas E. Stillman wore a rich gown of dark blue velvet, with side panels embroidered in tea roses and white satin trimmings. Diamonds were her jewels.
