The Princeton Triangle Club will present its new musical comedy, "The Scarlet Coat", at the Boston Opera House December 20, at 8.15 o'clock. The scene is laid in the Canadian Northwest, and the action promises to be fast and furious.

The proceeds from this performance will be divided between the Building Fund of the new Triangle Club Theatre at Princeton and the endowment fund of Harvard University. The Triangle Club is coming to Boston at the invitation of the Hasty Pudding Club and the New England Association of Princeton alumni.

The prices for the Boston performance range from 50 cents to $3. The tickets are on sale at Leavitt and Peirce's and Herrick's.
