The most recent and one of the most careful surveys of the history of the dispute between Baltimore and Penn and of the principles involved is in Walter B. Scaife’s “Boundary Dispute between Maryland and Pennsylvania,” in Pennsylvania Magazine of History (October, 1885, p. 241).
Chief among the maps bearing upon the question of the bounds are the following:—
A map of Virginia, Maryland, Pennsylvania, and East and West New Jersey, by John Thornton, which is without date, but probably from 1695 to 1700.[646]
A new map of Virginia and Maryland and the improved parts of Pennsylvania and New Jersey, revised by I. Senex, 1719.[647]
A short account of the first settlement of the Provinces of Virginia, Maryland, New York, and Pennsylvania by the English, to which is annexed a map of Maryland, according to the bounds mentioned in the charter and also of the adjacent country, anno 1630, London, 1735. This map is a large folding one called “A map of Virginia, according to Capt. John Smith’s map, published anno 1606; also of the adjacent county, called by the Dutch Niew Nederlant, anno 1630, by John Senex, 1735.”[648]
The map accompanying the agreement of July 4, 1760, between Baltimore and Penn, is reproduced, with the text of that document, in the Pennsylvania Archives, iv. (1853), p.3.
Respecting the bounds in dispute between Maryland and Virginia, the fullest summary of claims and evidence is in the Report and Journal of Proceedings of the joint Commissioners to adjust the boundary line of the States of Maryland and Virginia, Annapolis, 1874. This volume gives statements of the Maryland (p. 63) and Virginia (p. 233) claims, with depositions of witnesses. The volume as deposited in public libraries is accompanied by a coast survey chart, in which the determined bounds are marked, with the attestation of the governor of Maryland.[649]
