Even sleep, which I greatly needed, and for which I earnestly longed, did not come to me easily; for each time that I seemed to be dropping gently away into unconsciousness I would be roused by the feeling that I was holding fast to the chain again, and so was sliding down the long curve among the shadows, with the great walls of the cañon towering infinitely above me, and with the black depth below. And in my sleep I made again the dreadful passage, and heard the clinking of the chain as it parted, and the rattle of it as it struck the rocks, and felt the grasp of Rayburn as he caught me, just as the bar was twitched out of my hands--and so woke to find Young shaking me, and to hear him say: "There's no earthly sense in your kickin' around that way, Professor; an', anyhow, it's time t' get up. It's just a wonder how these Mexican mornin's put life into a man. Why, there's a freshness in th' air that's goin' t' waste in this cañon that's fit t' make a coffin stand right up on end an' dance a jig!"
Even Fray Antonio, but for the soreness of his hurt, felt strong and well; and we ate another tin of meat--which was much less than we wanted to eat--and so started along the path hewn out of the side of the cliff; and what with the brightness and joyfulness of the morning, we certainly were in much higher spirits than was at all reasonable in the case of men who had had such close companionship with Death so short a time before, and who still stood a very fair chance of dying dismally of starvation. The knowledge that, by the falling of the chain, our retreat had been again cut off did not at all trouble us. Even could we have crossed the cañon, and so have retraced our steps, we could have gone no farther than the valley of the lake; and we could as well die here as there. And we were stayed by the reasonable conviction that the path which we were travelling upon certainly would lead us out of the mountains at last--even if it did not lead us to the hidden city that we sought.
For five or six miles we doubled on our course of the day before, going back along the cañon and seeing the path that we had followed a little below us on the other side; then, by a very easy grade, our course began to ascend, and went on rising until the other path was so far below us that it ceased to be distinguishable. Thus we came to within a few hundred feet of the top of the cliffs, when a sudden turn to the left carried us into a narrow cleft in the rock. Here the path was very sharply inclined upward for a little way; and for the remainder of the distance to the top we ascended a long series of rudely cut steps, so steep that our legs fairly cracked under us as we neared the end of them.
