Note 27 — Chapter V · THROUGH ARIZONA TO SAN DIEGO

James Duncan Graham was a member of Long's first expedition. In 1840 he was appointed commissioner for the survey of the Maine boundary and did good service in the settlement of that controversy. He was for a time principal astronomer of the Mexican Boundary Commission, but was recalled, on account of disagreements with Commissioner Bartlett, and made a separate report (Senate ex. doc. No. 121, 1st session, 32d Cong.). He reached the rank of colonel during the Civil War and died in 1865. Mt. Graham, Arizona, bears his name.
