There is at least one significant part of the trip that cannot be duplicated today. To the best of my knowledge, the Delaware and Raritan Canal is no longer a through route from New York harbor to the Delaware River. From New York harbor, one must now venture out into the Atlantic and enter the Intracoastal Waterway at Manasquan Inlet on the New Jersey shoreline. The route described in the book can be rejoined at the Delaware Bay end of the Chesapeake and Delaware Canal.
