Tintype, "surveyor with a vernier compass made by Levi Colton," c. 1870

Provides historical information and photographs pertaining to more than 300 surveying instruments used in America to delimit land and transport boundaries "since the first European colonists settled here some 400 years ago and turned the American landscape into property." Visitors may browse by 23 types of instruments—from alidades to zenith telescopes—and by 117 names of instrument makers. Informative texts on makers, types of instruments, and specific instruments run from one sentence to 300 words in length. Entries include bibliographic references. Of value for those studying the history of science and technology.
