After breaking a passage, through the entangled shrubs that grew across the only possible footing in this solitary wilderness, he went along the side of the expanding stream, which at every turning of the rocks increased in depth and violence. The rills from above, and other mountain brooks, pouring from abrupt falls down the craigs, covered him with spray, and intercepted his passage. Finding it impracticable to proceed through the rushing torrent of a cataract, whose distant roarings might have intimidated even a younger adventurer, he turned from its tumbling waters which burst upon his sight, and crept on his hands and knees up the opposite acclivity, catching by the fern and other weeds to stay him from falling back into the flood below. Prodigious craggy heights towered above his head as he ascended; while the rolling clouds which canopied their summits seemed descending to wrap him in their "fleecy skirts;" or the projecting rocks bending over the waters of the glen, left him only a narrow shelf in the cliff, along which he crept till it brought him to the mouth of a cavern. He must either enter it or return the way he came, or attempt the descent of overhanging precipices, which nothing could surmount but the pinions of their native birds. Above him was the mountain. Retread his footsteps until he had seen his beloved master, he was resolved not to do--to perish in these glens would be more tolerable to him; for while he moved forward, hope, even in the arms of death, would cheer him with the whisper that he was in the path of duty. He therefore entered the cavity, and passing on, soon perceived an aperture, through which emerging on the other side, he found himself again on the margin of the river. Having attained a wider bed, it left him a still narrower causeway to perform the remainder of his journey. Huge masses of rock, canopied with a thick umbrage of firs, beech, and weeping-birch, closed over the glen and almost excluded the light of day. But more anxious, as he calculated by the increased rapidity of the stream he must now be approaching the great fall near his master's concealment, Halbert redoubled his speed. But an unlooked-for obstacle baffled his progress. A growing gloom he had not observed in the sky excluded valley, having entirely overspread the heavens, at this moment suddenly discharged itself, amidst peals of thunder, in heavy floods of rain upon his head. Fearful of being overwhelmed by the streams, which now on all sides crossed his path, he kept upon the edge of the river, to be as far as possible from the influence of their violence. And thus he proceeded, slowly and with trepidation, through numerous defiles, and under the plunge of many a mountain-torrent, till the augmented storm of a world of waters, dashing from side to side, and boiling up with the noise and fury of the contending elements above, told him he was indeed not far from the fall of Corie Lynn.
