The Transit instrument at Kenyon College was originally placed on a solid, stone ledge in a southward-facing window in the observatory in the tower of Ascension Hall (1859). The main telescope was a 4" instrument with a lens made, in local legend, by Alvan Clark. Tall trees and light pollution have caused the observatory to be moved; the telescope is now in the Smithsonian Institution collection, and the transit is in storage in the Kenyon physics department.

   Astronomical transits have telescopes pivoted in the vertical plane, and accurate angular measurements can be made of the relative vertical position of a star using the divided circles. Normally the transit was set to the vertical plane was that of the meridian. A clock next to the instrument allowed the astronomer to note the time when the star passed the meridian.

   The transit instrument at the left was made by Fry and Shaw of New York.

   It is in the apparatus collection of Hobart and William Smith Colleges, and was probably bought by William Smith about 1900 for his private observatory.

   The instrument is about 55 cm in height,
