Mason-Dixon line traced by English mathematicians in 1763
Civil War enthusiasts recall how Charles Mason and Jeremiah Dixon drew the boundary between Pennsylvania, Delaware, and Maryland. A 1963 resurvey confirmed the markers' remarkable accuracy. Also included are a bridge column by Oswald and Jacoby and a grim note: only 23 of 146 prisoners in the Black Hole of Calcutta survived the night.
