St. John’s University conferred 2,146 undergraduate degrees at three graduation ceremonies held over the weekend.

The Rev. Donald J. Harrington, president of the university, gave the keynote address at all ceremonies for the 122d commencement exercises.

Addressing the students at the campus in Jamaica, Queens, yesterday, Father Harrington told the students that “the quality of life in society rests upon the quality of education in our grammar and high schools and in our colleges and universities.”

Referring to the rioting in Los Angeles, he said, “Regardless of how we interpret the events of the past month, regardless of where we seek to place the blame, I submit to you that an essential part of any solution must be the renewal of the educational system of our land.” Industry, Health, Banking

Cornell University’s 124th commencement took place yesterday in a cold rain with temperatures in the 30’s, prompting the university’s president, Frank H. T. Rhodes, to cut short his prepared remarks to the 5,900 graduates. University officials said it was the first time in 17 years that it had rained on commencement.

Each of the graduates of Cornell’s 11 schools and colleges at the ceremony, which was still held outdoors on the campus in Ithaca, N.Y., was given a red rose. Mr. Rhodes used the occasion to remind them to “take time to smell the roses.”
