The mountains reach an elevation of ten thousand feet within a few miles of the college and these with the nearby ocean afford many special advantages for the study of things not in books. The college is a small one of the New England type with high standards of scholarship. A large proportion of the graduates go on with advanced work in the large universities. In addition, well-manned departments of music and art afford exceptional advantages.
