Map of the Country betwen Albemarle Sound and Lake Erie, comprehending the whole of Virginia, Maryland, Delaware and Pennsylvania, with parts of several other of the United States of America. Engraved for the Notes on Virginia. The country on the eaternside of the Alleganey Mountains is taken from Fry and Jefferson's Map of Virginia, and Scull's map of Pennsylvania, which were constructed manily on actual survey; that on the westernside of the Alleganey, is taken from Hutchins, who went over the principal water courses, with a compass and log line, correcting his work by observations of latitude: additions have been made where they could be made on sure ground.
