The appalling peril from which he had thus a second time so narrowly escaped, inflicted a terrible shock on George's nerves, and it was some time before he could find courage to once more raise his head and look about him. The reflection, however, that two men, one of them utterly helpless, were in the same perilous situation as himself--having indeed been brought directly into it by him--helped him to once more recover the command of his nerves, and, somewhat ashamed of their unexpected weakness, he scrambled to his feet and set out to explore in the opposite direction. By the time that he had once more reached the point where Tom sat patiently awaiting him, the dusk was closing down upon the landscape with all the rapidity peculiar to the tropics, and, shrouded as they were in the deep shadow of the precipice, it was already difficult for them to see each other clearly. This meant still another danger added to those which already confronted them, and George felt that, unless a way of escape could quickly be found, they would be compelled to remain where they were all night, a prospect which involved so many horrible contingencies that he dared not allow his mind to dwell upon it, but, turning his attention strictly to the matter in hand, hurried away on his quest to the westward. In this direction he was more successful, the ledge, at a distance of some thirty yards, running into a steep earthy slope, some ten or a dozen yards in height, above which the precipice again rose sheer to the top. And, as far as he could see in the quick-gathering darkness, this precipice again presented a rocky face, up the inequalities of which it might be possible for them to climb. But a single glance was enough to assure George that the most perilous portion of their journey still lay before them. In the first place, the slope was frightfully steep, rising at an angle of fully fifty degrees from the horizontal; and, in the next place, it was covered with a long thick growth of grass, rendering its face almost as slippery as ice. And its lower edge terminated abruptly in a vertical overhanging face, similar to that which towered above the place where he had left Tom and Walford, so that, should either of them slip in traversing this dangerous part of their journey, they must all, lashed together as they were, inevitably slide and roll helplessly down and over the edge into the depths below. As George contemplated the fearful dangers attending their further progress, the idea occurred to him that perhaps, after all, now that their pursuers had gone, and the ground was left clear below, it would be better to retrace their steps and endeavour to find another and more practicable way out of the ravine.
