Description
Established in 1879, the U.S. Geological Survey tested distance measurers to see which best suited their purposes. Those that failed muster were sent to the Smithsonian in 1907. This example—said to be a Keith odometer that counted revolutions of a wagon wheel—is one of those instruments.
