Before they departed, Jock's father explained that he had come over to the camp in the early evening with a boatman, but when he discovered that no one was there, he had decided to remain until they returned. As it was now after ten o'clock, he had begun to feel somewhat uneasy; but the fact that all were gone, and that everything about the camp seemed to be in good order, had led him to believe that they could be in no danger, at all events, and so he had waited until the time when his patience had been amply rewarded.
