The curriculum covers four years in each of the courses-classical, literary, and scientific. There is also the Introductory Year for young pupils, which gives thorough training in the elementary English Branches. Morgan Hall for girls, West Hall and East Hall for boys, contain comfortable rooms with equipment modern in all respects. The laboratories are amply furnished with apparatus for Chemistry, Physics, Physiography, and Botany. The library contains four thousand well-selected books for general and special reading, and offers in its reading room the choicest literature of the day. The tennis courts and the athletic field, with space for football and baseball games, track athletics and bicycle riding, give full opportunity and encouragement to outdoor athletics. Gymnasiums in Morgan and East Halls provide for indoor physical training.
