An evenly balanced program of studies and extra-curricular activities is the key to a successful career at Radcliffe, president Wilbur J. Jordan told almost 1200 Annex students--240 of them Freshmen--who assembled yesterday in the First Congregational Church for Opening Day exercises.

Calls for Leadership

"I think," he said, that it is most important that while here you should participate through your clubs, your reading, and your thinking in the issues and problems of our day."

In that vein, President Jordan cited the need for preparation in "leadership and responsibility" in the postwar college world today and added that such qualities could most fully be achieved by "a leisurely and vicarious participation in the past of mankind, and in coming to an understanding of the sentiments that have inspired and moved men."

He concluded, "Your task in a troubled, a difficult, and an exciting world today is to prepare yourselves for the future."

Newest Professor Welcomed

President Jordan also welcomed Professor Helen Maud Cam of Cambridge University, who entered her first year as the new Zemurray-Radcliffe professor of History at yesterday's exercises.

A reception for officers of the college and graduate students in Longfellow Hall and lunch at the Applan Way graduate house followed President Jordan's address and benediction. Annex undergraduates remained in the church for brief talks by Deans Wilma A. Kerby-Miller and Mildred F. Sherman, and for an address by Joan Projansky '49, president of the Student Government Association.
