In 1840 the school was moved two blocks up the hill to its present location; the first building was constructed the same year and is still in use as a reception hall and museum.

In 1914 the school was purchased by Theodore K. Long, a graduate of Bloomfield Academy and Yale who became a prominent Chicago lawyer and city councilman.

This peer leadership, along with faculty members serving as role models, had intended to help cadets succeed in college and/or military service.

Glee club, music lessons, "Red & Blue" (the campus newspaper), and "Carsonian" (yearbook) were just a few of the many extracurricular activities available.

Cadets could also participate in football, baseball, basketball, tennis, soccer, track and field, wrestling, and rifle team.
