Scope and Content: To establish accurate Massachusetts town boundaries, and eventually interstate boundaries as well, beginning in 1885 the Topographical Survey Commission (replaced in this function in 1901 by the Board of Harbor and Land Commissioners) sent out field teams to establish and describe triangulation stations and to set monuments designating boundary lines.  These position tables are based on the notebooks of the survey teams, with a few earlier observations included as well.  Calculations were verified, adjusted, and prepared by the U.S. Coast and Geodetic Survey.
Arrangement: Arranged chronologically, thereunder by locality
