Hackley Hall, originally a frame men's dormitory built in 1808, was destroyed by fire in 1900. Its replacement, built the next year, was described in the 1902-1903 school catalog as "a beautiful brick building, the gift of Mrs. Frances Hackley of New York." With 16 student rooms, two classrooms, and spaces for assemblies and receptions, Hackley was indeed a versatile facility. Dormitory life was part of the school's strict regimen for male and female students alike. Students also worked various campus jobs to lower their educational costs.
All earnings made by students who work part of their way through the school must be used for their education in this school. Students will not be permitted to draw their earnings in cash for frivolous or miscellaneous purposes.
