The Astronomical Observatory is situated upon Mount Jefferson, which
furnishes an unobstructed horizon. The principal building is a rotunda

forty-five feet in diameter, which contains the great Clark refractor of
twenty-six inches aperture. The instrument and building are the gift of the
late Leander J. McCormick, Esq., of Chicago. The telescope is fitted with
micrometer, photometer, and a plate-holder for stellar photography. The
computing rooms adjoining contain clocks, chronograph, machines for
measuring astronomical photographs and spectrograms, and an excellent
working library. In a smaller building are a three-inch transit and a six-inch
equatorial.

A temporary Students' Observatory, erected in the rear of Dawson's
Row, is intended primarily for the use of students in Astronomy B1.
