"you must have made the Dramat"

The Harvard-Radcliffe Dramatic Club, founded in 1908, is a student-run organization that brings together performing arts across the campus. Alternatively, Herbert could be referring to Hasty Pudding Theatricals, a Harvard society which, being formed in 1795, is the oldest of American collegiate dramatic clubs. Though many notable actors and playwrights have been involved in The Pudding’s productions, it is better known for burlesque musicals than serious acting.
