Gobelin tapestries and huge towering plants transformed the barnlike assembly room of the Brooklyn Academy of Music into one of the coziest of dancing parlors last evening, when the members of the Ihpetonga Society held their first ball of this season.

None of the 300 guests had arrived until after 10 'clock, but they made up for the delay by eating one of Pinard's most enjoyable suppers at midnight, and dancing the German until late into the morning. The decorations were all by Klunder.

Mr. Amory S. Carhart led the cotillion with Miss Brookman. During the supper the mandolin players furnished pleasant music. All the arrangements were conducted by a committee composed of Messrs. J.Jay Pierrepont, Charles E. Bill, Jr., A.S. Carhart, W.B. Dickerman, A.M. Hatch, and Frederic Cromwell.
