The roots of this attractive -- but hydrographically imprecise -- chart may be traced to Captain Cyprian Southack, who explored Portland harbor in 1698. Southack published his chart in London in 1720 and it appeared, with minor modifications, in many editions of The English Pilot between 1721 and the 1790s. Here it has been appropriated by the French, where it appeared in Neptune Americo-Septentrional at the time of the American Revolution. By the time this French version appeared, the British had vastly superior charts of Casco Bay that were included in The Atlantic Neptune.
