While they hesitated, not knowing which way to turn nor what to do, the clouds below them rolled away, though above and back of them they remained as dense as ever, and a view of what lay before them was unfolded.

Rocks, ice, and snow; sheer walls rising on either side of them, and a precipitous slope forming an almost vertical descent of a thousand feet in front. There were but three things to do: Go back the way they had come, which was so wellnigh impossible that they did not give it a second thought; remain where they were, which meant a certain and speedy death; or make their way down that rocky wall. They crept to its brink and looked over, anxiously scanning its every feature and calculating their chances. The first thirty feet were sheer and smooth. Then came a narrow shelf, below which they could see others at irregular intervals.

"There is only one way to do it," said Bonny, "and that is by the rope. I will go first, and you must follow."

"I'll try," replied Alaric, with a very pale face but a brave voice.

So Bonny, with the knowledge of knots that he had learned on shipboard, made a noose that would not slip in one end of their rope, tied half a dozen knots along its length for hand-holds, and fastened its other end about his body. Then he looped the noose over a jutting point of rock, and, slipping cautiously over the brink, allowed himself to slide slowly down.

It made Alaric so giddy to watch him that he closed his eyes, nor did he open them until a cheery "All right, Rick!" assured him of his comrade's safety. Now came his turn, and as he hung by that slender cord he was devoutly thankful for the strength that the past few weeks had put into his arms. He too reached the ledge in safety, and then, with great difficulty, on account of the narrowness of their foothold, they managed to slip the noose off its resting-place. Now they must go forward, for there was no longer a chance of going back. In vain, though, did they search that smooth ledge for a point that would hold their noose. There was none, and the next shelf was twenty feet below.

"We must climb it, Rick, and this time you must go first. Put the loop under your arms, and I will do my best to hold you if you slip; but don't take any chances, or count too much on me being able to do it."

There were little cracks and slight projections. Bonny held the rope reassuringly taut, and at length the feat was accomplished. Then Alaric took in the slack of the rope as Bonny, tied to its other end, made the same perilous descent.

So, with strained arms, aching legs, and fingers worn to the quick from clutching the rough granite, they made their slow way from ledge to ledge, gaining courage and coolness as they successfully overcame each difficulty, until they estimated that they had descended fully five hundred feet. Now came another smooth face absolutely without a crevice that they could discover, and the next ledge below was farther away than the length of their dangling rope. There was, however, a projection where they stood, over which they could loop the noose.

"We've got to do it," said Bonny, stoutly, "and I only hope the drop at the end isn't so long as it looks." Thus saying, he slipped cautiously over the edge, let himself down to the end of the rope, dropped ten feet, staggered, and seemed about to fall, but saved himself by a violent effort. Alaric followed, and also made the drop, but whirled half round in so doing, and but for Bonny's quick clutch would have gone over the edge.
