A series of interdormitory smokers for the class of 1915 will be inaugurated this evening, when the Seniors living in Thayer Hall will act as hosts to the Seniors from Hollis and Stoughton in Thayer Common Room between 9 and 10.30 o'clock. These smokers are a feature of the Senior life in the Yard, and do much toward forming close friendships among members of the graduating class. In addition to those living in the dormitories named, all Seniors who do not room in the Yard are invited to the smoker. Refreshments will be served during the evening.
