Some brushwood, and one or two stunted trees, gave him now and then a hold for his hands; and occasional ledges in the rock, a resting for his foot; but still one false step, one failing nerve, and he must have fallen backwards and been dashed to pieces; but to Arthur the danger was his safety.

Where he was going, indeed he knew not.

He could see no further than the summit of the crag, which appeared like a line against the sky; but any bewilderment were preferable to the strange stagnation towards outward objects, which had enwrapped him ten minutes before.
Panting, breathless, almost exhausted, he reached the summit, and before him yawned a chasm, dark, fathomless, as if nature in some wild convulsion had rent the rock asunder.

The level ground on which he stood was barely four feet square; behind him sloped the most precipitous side of the crag, devoid of tree or bush, and slippery from the constant moisture that formed a deep black pool at its base.
Stanley hazarded but one glance behind, then looked steadily forward, till his eye seemed accustomed to the width of the chasm, which did not exceed three feet.

He fixed his hold firmly on a blasted trunk growing within the chasm; It shook--gave way--another moment and he would have been lost; but in that moment he loosed his hold, clasped both hands above his head, and successfully made the leap--aware only of the immense effort by the exhaustion which followed compelling him to sink down on the grass, deprived even of energy to look around him.
So marvellous was the change of scenery on which his eyes unclosed, that he started to his feet, bewildered.
