Scope and Content: A survey of the Commonwealth was commissioned by the governor in 1830 in order to prepare an accurate map of Massachusetts.  For the trigonometrical phase of the survey, teams took angle measurements from primary and secondary stations and recorded them in field notebooks ((M-Ar)764X).  This series, consolidating measurements from those notebooks, consists of computations of the triangles establishing the exact location of the stations.
Arrangement: Arranged by station number
