Map of Allentown (Northampton Towne), about 1842 by Phaon Jarrett. This was the second map of the town, showing the city limits still those of 1782, right after the Revolutionary War. A suburb, known as "Lehigh Port" was being developed between the Jordan Creek and Lehigh River. Also, a port for canal boats had been built on the west bank of the Lehigh directly north of Dam Number 7. (Holdings of the Lehigh County Historical Society)
