Captain Barnsleys chart of the New England coast replaced that of Cyprian Southack in the 1767 edition of The English Pilot, the standard English marine atlas throughout the eighteenth century.

Oriented with north to the upper right, this chart depicts important towns and harbors along the coast from Cape Cod to Casco Bay. Of interest at the upper right are four headland views, which provided perspective views to assist captains sailing into these harbors.
