"Now, sodger," cried Ralph, "stick close to the trough; and if you ever seed etarnity at midnight, you'll see a small sample now!" With that, he pushed the canoe into the stream, and Roland, urging his terrified steed with voice and spur, and leading his cousin's equally alarmed palfrey, leaped in after him, calling to Dodge and Emperor to follow. But how they followed, or whether they followed at all, it was not easy at that moment to determine; for a bright flash of lightning, glaring over the river, vanished suddenly, leaving all in double darkness, and the impetuous rush of the current whirled him he knew not whither; while the crash of the thunder that followed, prevented his hearing any other noise, save the increasing and never absent roar of the waters. Another flash illuminated the scene, and during its short-lived radiance he perceived himself flying, as it almost seemed, through the water, borne along by a furious current betwixt what appeared to him two lofty walls of crag and forest, towards those obstructions in the channel, which, in times of flood, converted the whole river into a boiling caldron. They were masses of rock, among which had lodged rafts of drift timber, forming a dam or barrier on either side of the river, from which the descending floods were whirled into a central channel, ample enough in the dry season to discharge the waters in quiet, but through which they were now driven with all the hurry and rage of a torrent. The scene, viewed in the momentary glare of the lightning, was indeed terrific: the dark and rugged walls on either side, the ramparts of timber of every shape and size, from the little willow sapling to the full-grown sycamore piled high above the rocks, and the rushing gulf betwixt them, made up a spectacle sufficient to appal the stoutest heart; and Roland gasped for breath, as he beheld the little canoe whirl into the narrow chasm, and then vanish, even before the light was over, as if swallowed up in its boiling vortex.
