Description
The U.S. Geological Society was organized in 1879 and, in 1887, began using thin steel tapes under a uniform tension to measure baselines. This example is 300 feet long with triangular brass handles, and no apparent markings. In use it would be stretched to a tension of 15 pounds. The Survey transferred it to the Smithsonian in 1907.
