A recent newspaper report claimed that an academic rebellion was brewing on the Princeton University campus. According to the report, graduate students were barred from the main dining hall because they refused to wear the traditional academic gown. We decided to investigate in our usual dispassionate, scientific style.
We are pleased to affirm that the newspaper story which claimed 30 Princeton University graduate students refused to wear the newly reinstituted academic gown is spurious. Newspaper had students refusing to wear gowns to dinner because they claimed the voluminous folds got in the way of the soup and mashed potatoes. For their temerity, the dean supposedly refused students admittance to the main dining hall.
Hubert N. Alyea, Frick Chemical Lab. at Princeton, tells us that the newspaper account, like that of Mark Twain's death, is greatly exaggerated. Fact of the matter is that Proctor Hall, the main dining room, cannot accommodate all the students. Each night 30 latecomers are forced to eat in the annex and not because they refuse to wear gowns as the newspaper claimed.
