The Class of 1955 will gather for the last time as undergraduates in front of Widener Library at 10 a.m. today to march to the annual Class Day Exercises in Sever Quadrangle. The traditional farewell ceremonies will be held at 10:30 a.m.

Graduating seniors today will wear their academic tassels on the right side of their mortar boards. Tomorrow, the tassels will move to the other side, and '55 will join the Alumni.

The procession will be led by Class Marshals Clifford L. Alexander, Jr., J. Timothy Anderson, and Frank H. White. The Band and representatives of the classes of 1905 and 1930 will also march in the parade.

Following a prayer by the Rev. George A. Buttrick, chairman of the Board of Preachers, Richard L. Bushman of Salt Lake City will deliver the Class Oration, and Allen R. Grossman of Minneapolis will read his Class Poem. The humorous Ivy Oration will be given by Frederic M. Kimball of St. Louis.

The Ames Award will be presented by R. Colin MacLaurin '33 to two outstanding seniors whose names will be announced at the ceremonies. Established in memory of Richard G. and Harry R. Ames, two brothers who died at sea, the prize is given for self-reliance, character, and leadership.
