Classicly

Viewed from the shore, not a sign of life would have been seen at first. Some invisible but skilful hand seemed to dip and sweep the long guiding oars and keep the boat in the channel. But a closer view would have shown a small, dark spot-like appearance above the gunwale at the stern, which at long intervals changed its position, and then for so long a time remained stationary as to give the impression that it was a part of the boat itself. This small object was a coon-skin cap, and it rested upon the head of him who was guiding this boat through the perils that environ it. A nearer approach, and a low hum, as though persons were conversing in the cabin, might have been heard; but no other appearances of life would have been seen upon the outside, except the one individual referred to.
