| [Vous devez être inscrit et connecté pour voir cette image]Old Swing Ferry at Buffalo Rapids near Miles City." The overhead cable and the pully to which the two ropes were attached are not shown. By lengthening or shortening a cable the "forward" end of the ferry could be pointed upstream and the pressure of the current flowing along the hull would then propel the ferry to the other side. There the adjustment would be reversed for the return trip. | |
