The reel contains a journal of the activities of Charles Mason and Jeremiah Dixon, the commissioners who surveyed a boundary between the provinces of Pennsylvania and Maryland. Before the Civil War, the boundary was considered the dividing line between slave and non-slave states. The journal includes a series of topographical notes and letters received by the commissioners during their mission.
An uncataloged guide, Journal of Charles Mason Kent During the Survey of the Mason and Dixon Line, is in the Special Collections Office. The same information is reproduced at the beginning of the reel.
