College Inn

The College Inn, just across the street, is owned and operated by Mr. James C. Gilbert. Mr. Gilbert has made his place of business attractive and pleasant for students. After the game, after the lecture, after the play, it is Jim who serves us hot sandwiches and ice cream. His hot lunches are both satisfying and economical and many students make the Inn a regular boarding place at a very reasonable cost.

Mr. Gilbert is our friend and booster in all school activities. When there is a game, he is there; when a play is given, he is there; when a lyceum number is announced, behold he is there. We owe him our support.
