James Johnson, Pilgrimages to the Spas in Pursuit of Health and Recreation
“ When one, two, or more have arrived at the dam, the head of the raft is brought close to the sluice—the gate is opened—and away darts the raft, with a loud noise and fracas—dashing against the rocks—each joint, as it passes over the dam, rising up like the dorsal fin of a huge whale rolling about in the sea. In this way they are conveyed from the mountains to the Rhine—the raftlets augmenting in breadth, or number of trees, in proportion as the stream augments and enlarges into a river. As every mountain must have a valley, so every valley must have a rivulet. ”
