The Astronomical Observatory is situated upon an elevation
known as Mount Jefferson, which furnishes an unobstructed horizon.
The principal building is a rotunda forty-five feet in diameter, and
contains the great Clark refractor of twenty-six inches aperture.
The building and instrument are the gift of Leander J. McCormick,
Esq., of Chicago. The computing rooms are adjoining, and contain
clock, chronograph, etc., and a working library. In a smaller building
are a three-inch transit and a six-inch equatorial.
A temporary Student's Observatory, erected in the rear of
Dawson's Row, is intended more especially for the use of students
in Course B1.
For summer-school courses in Astronomy, on which college
credit will be allowed, see p. 278.
