Early American History Note

The Mason and Dixon Survey Collection consists of two volumes relating to their work drawing a border between Pennsylvania and Maryland and a box of correspondence. This entry describes the two volumes. One contains the Penn family's costs, which goes into specific details about items purchased and used for the venture. The second volume is a manuscript copy of the commissioners' minutes from 1760-1768. The commissioners were representatives of both Baltimore and Penn, and gave directions to Mason and Dixon. The minutes contain negotiations between the commissioners, which provide insight into surveying methods and the various disagreements between the two sides about boundaries, particularly as they relate to the Delmarva Peninsula. There are a few mentions of Indians and diplomacy, especially around 1767 when Mason and Dixon were extending the line into the Ohio Country.
