It was as if the angels of the sky were noiselessly casting their fleecy veils of light over and into the awful depths below, and driving away the crouching monster of blackness that was thus roused from his slumber and forced to flee. Grand as was the scene, it was soothing in its effect upon the awed lad, who, leaning against the rock behind him, the stock of his rifle resting at his feet, surveyed it all with feelings that drew him nearer to heaven, and gave him a more vivid knowledge of the greatness and majesty of the Author of all that he saw and felt. Standing thus, with his emotions stirred to their profoundest depths, Jack Dudley took no note of the passage of time. Midnight came and passed, and still he held his post, wondering, admiring and worshipping, as must puny man when brought face to face with such exhibitions of Omnipotence. It was an unromantic ending to this experience that, forgetful of the consequences of what he did, he finally became sensible of the irksomeness of his standing position, and sat down, with his back to the rock, that he might enjoy it all without fatigue of body. Need it be said what followed? He had not been seated ten minutes when his senses left him and he became as unconscious as Fred Greenwood, asleep in the cavern, on the other side of the smouldering fire. The hours passed until the light of the moon paled before the rosy hues of the rising sun, and still the boys slumbered and knew naught of what was passing around them. CHAPTER X. THE SIGNAL-FIRES. Jack Dudley was awakened by the sound of laughter. Opening his eyes, he stared about him confusedly, unable for some moments to recall his situation. Fred Greenwood stood in front of him, shaking so much with mirth that he could scarcely stand. "O faithful sentinel!" he said; "how well thou hast kept thy trust!" "I don't see anything to laugh at," replied Jack, rising to his feet and rubbing his eyes; "you would have done the same if you had been in my place." "Perhaps I should, and then the laugh would have been on me. But we have cause to be thankful that, while no harm has come to us, we have had a good night's rest. I suppose you dropped into slumber almost as soon as I did." "No, I didn't," persisted the elder; "I stood here a long time, but made the mistake of sitting down for a few minutes, just before it was time to call you. I ought to have known better, and shall never do the like again." "Well, we have been fortunate and it has taught us both a lesson. Let's attend to our toilet and have breakfast." They laved their faces and hands in the cold stream of clear water running near them, combed their hair, stretched and limbered arms and legs by a series of gymnastics to which they were accustomed, and then, returning to the mouth of the cavern, found, by raking over the ashes, that enough live embers remained to broil the venison more acceptably than any meal that had been prepared since coming to the region.
