Toby earnestly conjured me to continue the ascent, assuring me that a little more exertion would bring us to the summit, and that then in less than five minutes we should find ourselves at the brink of the stream, which must necessarily flow on the other side of the ridge. ‘Do not,’ he exclaimed, ‘turn back, now that we have proceeded thus far; for I tell you that neither of us will have the courage to repeat the attempt, if once more we find ourselves looking up to where we now are from the bottom of these rocks!’ I was not yet so perfectly beside myself as to be heedless of these representations, and therefore toiled on, ineffectually endeavouring to appease the thirst which consumed me, by thinking that in a short time I should be able to gratify it to my heart’s content. At last we gained the top of the second elevation, the loftiest of those I have described as extending in parallel lines between us and the valley we desired to reach. It commanded a view of the whole intervening distance; and, discouraged as I was by other circumstances, this prospect plunged me into the very depths of despair. Nothing but dark and fearful chasms, separated by sharp-crested and perpendicular ridges as far as the eye could reach. Could we have stepped from summit to summit of these steep but narrow elevations we could easily have accomplished the distance; but we must penetrate to the bottom of every yawning gulf, and scale in succession every one of the eminences before us. Even Toby, although not suffering as I did, was not proof against the disheartening influences of the sight. But we did not long stand to contemplate it, impatient as I was to reach the waters of the torrent which flowed beneath us. With an insensibility to danger which I cannot call to mind without shuddering, we threw ourselves down the depths of the ravine, startling its savage solitudes with the echoes produced by the falling fragments of rock we every moment dislodged from their places, careless of the insecurity of our footing, and reckless whether the slight roots and twigs we clutched at sustained us for the while, or treacherously yielded to our grasp. For my own part, I scarcely knew whether I was helplessly falling from the heights above, or whether the fearful rapidity with which I descended was an act of my own volition.
