712 The National Geographic Magazine I' .! Arthur Ellis Plodding Nellie Tows a Pleasure Barge Past Wilderness Scenes in Old Georgetown, D. C. Sunday strollers look down upon the Chesapeake & Ohio Canal from Wisconsin Avenue bridge, only survivor of four old stone spans. Once the 185-mile waterway floated lumber, flour, and coal between Cumberland, Maryland, and tidewater. In 1871 it had 540 boats in service. Flood and railroad ended its commercial career in 1924. Now the National Park Service conducts week-end excursion trips along four miles of restored waterway. Lec turers accompany the tours. "Never lost a passenger from seasickness yet," they boast.
