Though Princeton's use of crossword conundrums is new in university methods, the cross-word principle has long been employed at Harvard in those delightfully risque little pamphlets: "Notes on the Choice of Electives", "Rules Relating to College Studies", and the more popular editions of "Courses of Instruction". Not until their fourth year of residence do students learn the interesting knack of reading them so as to discover any meaning at all. Even then, the hazards of starred courses and of courses omitted year in and year out supply difficulties enough to make results both entertaining and uncertain.
