Surveyor's Compass

Usage conditions apply
The floral decoration on the face of this compass is similar to that found on many other instruments made in New York around 1850. The rim is graduated every 30 minutes. A north–south level vial is on the north arm, and an east–west level vial is on the south arm. The signature reads "L. Colton, New York." As the tag on the south arm indicates, the compass belonged to the University of Pittsburgh.
Levi Colton (1803-1885) was born in Massachusetts, and trained as a jeweler and silversmith. He may have learned the art of instrument making from Richard Patten, for whom he worked in Washington, D.C. in 1846, and who described Colton as “a quite steady and industrious man.” Around 1850 Colton was making compasses in New York City, and in the mid-1850s he was making compasses in Hartford, Conn.
