Having crossed a second rocky ridge, like the first, when I was beginning to ascend the third, the Indian, whom I had left on the shore some fifty rods behind, beckoned to me to come to him, but I made sign that I would first ascend the highest rock before me, whence I expected to see the lake. My companion accompanied me to the top. This was formed just like the others. Being struck with the perfect parallelism of these singular rock-hills, however much one might be in advance of another, I took out my compass and found that they lay northwest and southeast, the rock being on its edge, and sharp edges they were. This one, to speak from memory, was perhaps a third of a mile in length, but quite narrow, rising gradually from the northwest to the height of about eighty feet, but steep on the southeast end. The southwest side was as steep as an ordinary roof, or as we could safely climb; the northeast was an abrupt precipice from which you could jump clean to the bottom, near which the river flowed; while the level top of the ridge, on which you walked along, was only from one to three or four feet in width. For a rude illustration, take the half of a pear cut in two lengthwise, lay it on its flat side, the stem to the northwest, and then halve it vertically in the direction of its length, keeping the southwest half. Such was the general form.

There was a remarkable series of these great rock-waves revealed by the burning; breakers, as it were. No wonder that the river that found its way through them was rapid and obstructed by falls. No doubt the absence of soil on these rocks, or its dryness where there was any, caused this to be a very thorough burning. We could see the lake over the woods, two or three miles ahead, and that the river made an abrupt turn southward around the northwest end of the cliff on which we stood, or a little above us, so that we had cut off a bend, and that there was an important fall in it a short distance below us. I could see the canoe a hundred rods behind, but now on the opposite shore, and supposed that the Indian had concluded to take out and carry round some bad rapids on that side, and that that might be what he had beckoned to me for; but after waiting a while I could still see nothing of him, and I observed to my companion that I wondered where he was, though I began to suspect that he had gone inland to look for the lake from some hill-top on that side, as we had done. This proved to be the case; for after I had started to return to the canoe, I heard a faint halloo, and descried him on the top of a distant rocky hill on that side. But as, after a long time had elapsed, I still saw his canoe in the same place, and he had not returned to it, and appeared in no hurry to do so, and, moreover, as I remembered that he had previously beckoned to me, I thought that there might be something more to delay him than I knew, and began to return northwest, along the ridge, toward the angle in the river. My companion, who had just been separated from us, and had even contemplated the necessity of camping alone, wishing to husband his steps, and yet to keep with us, inquired where I was going; to which I answered, that I was going far enough back to communicate with the Indian, and that then I thought we had better go along the shore together, and keep him in sight.

When we reached the shore, the Indian appeared from out the woods on the opposite side, but on account of the roar of the water it was difficult to communicate with him.
