Scope and Content: To establish accurate Massachusetts town boundaries, beginning in 1885 the Topographical Survey Commission sent out field teams to establish and describe triangulation stations, and to set monuments designating boundary lines.  These volumes of computations of the town boundary triangulation are based on field notebooks of the survey teams.  Computations were verified, adjusted, and prepared by the U.S. Coast and Geodetic Survey.
