More than 800 Seniors will begin their war-shorn graduation exercises tomorrow evening as the College opens its 291st Commencement Week.

The Yale baseball game at 3 o'clock, a Class supper at 6 o'clock, a Glee Club and Pierian Sodality concert, and the annual Ivy Oration at 8 o'clock in the Kirkland House triangle will take the place of the colorful Stadium ceremonies and confetti battles, cancelled this June as a war economy.

R. Bruce Stedman, president of the Glee Club, will conduct the first part of the Concert program.

Malcolm H. Holmes, director of the Harvard, Radcliffe and Wellesley orchestras, will then conduct the Pierian Sodality of 1808 in five orchestral selections: Sinfonia, "To Thee Alone be Glory," by Bach; Symphony No. 39 in E Flat, Minuet: Allegretto, by Mozart; Polka from "The Bartered Bride," by Smetana; Polka from "The Golden Age," by Shostakovitch; and March from "Peter and the Wolf," by Prokoflef.

Phinizy, Ivy Orator

Coles H. Phinizy, former president of the Lampoon will then give the Ivy Oration, a traditionally humorous summarization of the four-year history of the Senior Class.

Myron Oppenheimer and Vern K. Miller will next offer a series of "Undergraduate Sketches." The Concert will then be resumed by the Glee Club, which will sing a negro spiritual, "Sit Down Servant," with Drue King '43, vice-president-elect of the club, as leader; Bachchanale from "La Belle Helene," by Offenbach; and Chorus from "The Yeoman of the Guard," by Sullivan.

Business School Alumni

More than 500 Business School alumni are expected to take part in their twelfth annual meeting tomorrow, at Baker Library, for a full day's discussion of "Mobilization of Man Power."

Speakers at the session will include Alexander Louden, Netherlands Ambassador to the United States; Sidney J. Weinberg, assistant to the chairman of W. P. B.; and Allyn B. McIntire, vice-chairman of the Naval Officer Procurement. The meeting will end with a dinner in Eliot House.
