Graduating Cliffies, their boyfriends, and their mommies and daddies drank champagne from little plastic cups in Hilles Library yesterday (above), and that was how Radcliffe began its Commencement Week activities.

500 Alumnae

Radcliffe expects 500 returning alumnae to participate in the festivities. The Class of 1943 will sponsor the traditional Silver Anniversary Dinner at the Radcliffe Graduate Center June 15 for classes from 1940 to 1946.

Other reunion classes are: 1906, 1908, 1913, 1914, 1918, 1923, 1933, 1947, 1958, and 1963.

Tomorrow more than 300 Cliffies will receive their degrees at the college's 86th Commencement Exercises. Speaking will be Walter E. Washington, Mayor-Commissioner of the District of Columbia.
