I perceived the truth of his words and I confess to a sinking of the heart, as I contemplated the work before us. I was never an adept in clambering, it addles my head; and, bad as it appeared by day, surely doubly bad would it prove by night. Yet there was little help for it, and I made shift to win back my oozing courage by more cheerful speech. "Odds, but that is no such trip as I would seek after, yet needs must if the devil drives," I said. "So, now, brother Cairnes, if you wilt consent to divide your store of food, we shall both front our night's work with stronger bodies."
"Saints' rest! and if we go over the edge," he replied, cheerfully emptying his bulging pockets on the rock, "it will be a comfort to bear loaded stomachs with us. It was ever against my pleasure to die half filled."
We lingered as long as possible over our meal, conversing in such a way as to encourage each other and indulging in frequent draughts from the clear stream. Nothing occurred to disturb us, and, finally, both yielded to the soothing influence of the drowsy evening, and, resting back upon the rocks, dropped asleep. I know not the hour of my awakening, yet it greatly heartened me to be greeted by the sight of a nearly full moon, and to observe how the clear silvery light flooded the rocks, revealing the winding path leading upward. To arouse Cairnes was no easy task, but at last we advanced on our path. The huge rocks overhead appeared to arch us in, while, with utmost caution, we crept along the narrow, irregular ledge, which at times was level, and anon rose abruptly like the steps of a stair; occasionally it wound about projecting rocks and over vast, unknown depths, until my brain whirled, while I hugged the smooth rock wall at my right, and felt cautiously forward for solid foothold.
I imagine we had progressed thus for upwards of three or four hundred yards, and were elevated so far above the stream that scarcely an echo of its noise assailed our ears even in the silence of the night, when suddenly we came to the end of our path. The rocky shelf was so narrow the very conception of turning about smote me with terror. Directly in front, extending to the very edge, stretched a solid wall of rock. My eyes sank to the shelf on which I stood. Lying close against the sheer cliff was the root of a tree, its trunk, perhaps a foot or more in diameter, stretching over the abyss, whose depth I durst not guess. I stooped cautiously, my heart throbbing, and ran my fingers along the bark.
