A freshman from Thayer Hall returned to Cambridge at 9:30 a.m. yesterday to end both a 38-hour surprise vacation and the worries of parents, proctor, and police.

Leaving a half-finished paper on his desk, Henry Fry '59 left by bus for Vermont Wednesday evening without informing anyone of his intentions to get away from it all. His roommate, Alec B. Dawson '59, became worried Thursday morning and notified the University police. Shortly afterward, Fry's parents flew to Boston from Mecaniesburg, Pa.
