Close to the very edge of the precipice, a mass of jagged rock stood out. Already Manley had disappeared, and the snow went thundering down. For a moment I felt inclined to let myself glide down also. Just then I heard a voice; it was Manley shouting out to us not to attempt to come to his rescue. When about to be hurled over the edge of the precipice, he had clutched the jutting rock, and held on for his life, while the snow went rushing by under his feet. He waited until it had ceased to fall, and then, clutching the sides of the rock, by a powerful effort slowly worked himself upward until at last he gained the firmer part of the snow. Still, he several times cried out to us not to attempt to join him, lest our united weight might again set the mass in motion.

“I have indeed been mercifully preserved,” he said, when, having rejoined us, we congratulated him on his escape. “I pray that we may succeed in getting down into the valley, although at present I see no path open to us.”

After climbing some way, we found a gap in the rocks, which, although full of snow, afforded a sufficiently firm footing to enable us to get on without much difficulty. From thence, although the descent was not without danger, we succeeded in reaching a broad ledge free from snow. Here some bushes grew, of sufficient size to afford us fuel; and sheltered in the hollow of a rock, we passed the night in tolerable comfort.

On the return of day we recommenced our search for a practicable way down the mountain; and happily finding it, we at length reached one of the lower heights of the wide valley I have mentioned. I call it a valley, but it was rather a large basin, surrounded, as far as the eye could reach, by lofty mountains.

“Now we are here, how are we ever to get out again?” I asked Manley.

“Where those rivers find an outlet, so probably shall we,” he answered. “There can be no doubt that two or perhaps more cañons lead into this basin,—some to the north and east, so far as I can judge, and others to the west,—and by them, without having any ascent to climb, we shall probably be able to make our way in the direction we wish to go.”

Having the day before us, we proceeded westward across the basin. We soon found, however, that it was anything but level. Large hills, many of which might have been dignified by the title of mountains, rose up in various directions. One object, however, engaged our attention in the far distance: it was a beautiful sheet of water, blue as the sky overhead—like a jewel in a setting of green.

Nowhere could we see any Indian wigwams, but here and there we observed what appeared like smoke rising above the trees.

“I very much doubt if what we see is smoke,” observed Manley; “it looks more like vapour; and, from the appearance of this region, I suspect that some volcanic action is going forward. However, we shall discover that as we proceed.”

Although we at first fancied we had reached the valley’s level, we found we had still a considerable descent to make, and that we could not hope to arrive that day on the banks of the lake. We therefore encamped on the borders of a forest overlooking a stream which evidently ran into the lake, and which would serve to guide us the next day. The stream was bordered by rocks of a curious form, but we had not time to examine them before it was dark, as we had to make our usual preparations for passing the night.
