Our young readers must bear in mind that these canoes could only go before the wind, or a little quartering, and therefore could not, like a boat, be luffed sharp into the wind, and beat out clear of danger; hence the boys preferred to take the sail in, and trust to their oars, with which they could, if they saw a breaker, pull away from it. At length they discovered a narrow passage, that seemed to lead in among the breakers to a high bluff, and rowed into it, having reefs and breakers on either side of them. They coasted along the bluff till they discovered beyond it a low point, and between them a cove with a little narrow beach. In the end of the high bluff was a large cave, into which the moon shone, partly revealing its extent. Here they determined to land, and build a brush camp. While they were looking about for a place to get up the rocky, steep shore, they stumbled upon this cave, and determined to explore it. It ran about twenty feet into the rock, which, being formed to a great extent of iron pyrites, had crumbled beneath the united forces of the frost and waves. John clambered up the bank, and found some dry brush, with which they made a torch. As they went in they found the bottom rose, and in the middle was a little elevation, somewhat higher than the rest. The walls were ragged, and just high enough to permit them to stand upright.
