Fauth Theodolite

<< >>
This was made between 1878 when the U. S. Coast Survey became the U. S. Coast and Geodetic Survey, and 1887 when Saegmuller began putting serial numbers on Fauth instruments. It was described variously as a Reconnaissance and Mining Transit or a Complete Transit Theodolite. Its horizontal and vertical circles, each of 4 inches diameter, are divided on silver, and read by opposite verniers to single minutes. New, it sold for $200. The marks read "Fauth & Co. Washn D.C." and "U.S.C.&G.S. No. 122."
