Bayly Janson-La Palme worked with Lois Green Carr on economic data about colonial Maryland. Ms. Janson-La Palme then did her own work on economic data about Saint Mary's County from 1790-1870. She relied on census data, assessment records, estate inventories, etc. Her dissertation was based on this material, although the analysis in the dissertation only went up through 1840. The voluminous handwritten data was later transcribed onto 5 1/4" floppy disks using PC WRITE. That data was run on the mainframe computer at the University of Maryland. The disks, spread sheets, and other printouts are at the Hall of Records of the Maryland Archives.
This is a copy of sheet 2 from Piney Point to Lower Cedar Point of a set of 4 navigation charts of the Potomac River. Creeks and other locations are named, but not land holders. The topography was artistically rendered on the Maryland side right next to watercourses and minimally on the Virginia side. There are several insets with information about tides, map symbols and sailing directions. The chart making was done by the United States Coast Survey. The data was gathered from 1858 to 1868, with publication in 1884.
