Walcott had joined the U.S. Geological Survey in 1879, and became Director of that organization in 1894. In 1907 he was named Secretary of the Smithsonian Institution. One inscription on the back of the compass reads: "C. D. WALCOTT U.S. GEOLOGICAL SURVEY WASHINGTON D.C. AUGUST 1894." Another reads: "SECRETARY SMITHSONIAN INSTITUTION 1907."
