Headed by Mrs. Delmar Leighton, the list of patronesses includes Mrs. James B. Conant, Mrs. Henry Chauncey, Mrs. Alfred C. Hanford, Mrs. Roger B. Merriman, and Mrs. E. A. Whitney.

William A. Cordingley, Jr. '40, head usher, will be assisted by John T. Devine '40, Thomas V. Healey '40, Samuel Hoare '40, John F. Kennedy '40, Albert L. Maguire '40, Peter E. Pratt '40, and Peter S. Thompson '40.

The attractive poster by Petty, famous Esquire artist, which has been displayed in the Union throughout the week as an advertisement for the dance, will be raffied off in the course of the evening.
