Bowles' Map of New England ca.1765

Bowles' New One-Sheet Map of New England, Boston, was based on well-known British cartographer Thomas Jeffery's Map of the Most Inhabited Part of New England which appeared in various editions from 1744 to 1755. This one sheet reduction of Jeffery's map dates to about 1765.

The Osher Map Library of the University of Southern Maine has a web based exhibit on the work of Jeffery, whose maps were critical to the American Revolution.
