The blank expression which overcast the visage of the younger traveller, and traces of which might be discerned in the physiognomy of the beast of burden, announced alarm and mortification at this unexpected and, as it seemed, insurmountable obstacle. Nor did the looks of the father, who presently after came up to the same spot, convey either hope or comfort. He stood with the others gazing on the misty gulf beneath them, and looking all around, but in vain, for some continuation of the path, which certainly had never been originally designed to terminate in this summary manner. As they stood uncertain what to do next, the son in vain attempting to discover some mode of passing onward, and the father about to propose that they should return by the road which had brought them hither, a loud howl of the wind, more wild than they had yet heard, swept down the valley. All being aware of the danger of being hurled from the precarious station which they occupied, snatched at bushes and rocks by which to secure themselves, and even the poor mule seemed to steady itself in order to withstand the approaching hurricane. The gust came with such unexpected fury that it appeared to the travellers to shake the very rock on which they stood, and would have swept them from its surface like so many dry leaves, had it not been for the momentary precautions which they had taken for their safety. But as the wind rushed down the glen, it completely removed for the space of three or four minutes the veil of mist which former gusts had only served to agitate or discompose, and showed them the nature and cause of the interruption which they had met with so unexpectedly. The rapid but correct eye of Arthur was then able to ascertain that the path, after leaving the platform of rock on which they stood, had originally passed upwards in the same direction along the edge of a steep bank of earth, which had then formed the upper covering of a stratum of precipitous rocks. But it had chanced, in some of the convulsions of nature which take place in those wild regions, where she works upon a scale so formidable, that the earth had made a slip, or almost a precipitous descent, from the rock, and been hurled downwards with the path, which was traced along the top, and with bushes, trees, or whatever grew upon it, into the channel of the stream; for such they could now discern the water beneath them to be, and not a lake, or an arm of a lake, as they had hitherto supposed.
