It was several seconds before the trickeries of nature, in the way of echoes, terminated and matters settled down to their natural quiet.  And then, when quiet came again, it was like that of a tomb—­deep, profound, and impressive.  The bent and listening ear could detect nothing that could be supposed to resemble the noise of the cascade, which had excited his wonder when he was stretched out upon the ground directly above it.

“This must be about forty miles round,” he said to himself, when he had waited for the reply until convinced that it was not forthcoming, “and I have strayed away altogether.”

The luxury of rest was so great, after his long, wearying toil, that he concluded that he might as well spend a half hour in that fashion as in any other.  The echoes and pains of his bruises had departed,—­or, more properly, perhaps they were consolidated with the aches and pains following upon the overtaxing of his limbs.

“Oh, dear!  How tired I am!” he sighed, as he stretched out his limbs.  “It seems to me that I won’t be able to walk again for a week.  I must rest awhile.”

His fatigue was so great that he was not conscious of any desire for food or rest.

“Maybe I will need that torch more after a time than I do now,” he added, as he looked listlessly at it.  “It seems good for a half hour yet, and I don’t want it.”  With this he thrust the burning end in the sand at his feet, and held it there until it was entirely extinguished, and he was wrapped again in the same impenetrable darkness.  So far as possible, he had become accustomed to this dreadful state of affairs.  He had been viewing and breathing the atmospheric blackness for many hours, although it may be doubted whether one who had spent so much of his life in the sunshine could ever become accustomed to the total deprivation of it.

Fred had assumed an easy position, where he could lay his head back, and, straightening out his legs, he made up his mind to enjoy the rest which he needed so badly.  When a lad is thoroughly and completely tired, it is difficult for him to think of anything else; and although, while walking, the fugitive was tormented by all manner of wild fancies and fears, yet when his efforts ceased, something like a reaction followed, and he sighed for rest, content to wait until he should be forced to face the difficulties again.

When he closed his eyes all sorts of lights danced before him, and strange, indescribable noises filled the air.  It seemed that impish figures were frolicking all around, sometimes grinning in his face, and then skurrying far away through the aisles of the gloom.  At last he slept.  The slumber was sweet and dreamless, carrying him through the entire night, and affording him the very rest and refreshment which he so sorely needed.

This sleep was nearly completed when Fred was aroused by some animal licking his face.  He arose with a start of exclamation and terror, and the animal growled and darted back several feet.  A pair of gleaming eyes flashed in the darkness—­the same pair which he had seen before.  The wolf had come back to him.
