During the 19th century, waterways were the highways of early American travel, connecting tiny villages to big cities, with horses and mules trotting along towpaths pulling canal boats. In the small town of Delphi, Indiana, travel started on the Wabash & Erie Canal — once the second longest canal in the world — in the early 1840s. Launching from here, a trip to New York Harbor would take about two weeks and require boarding four different vessels, including two canal boats and two steamships.
