Close upon our left ran the Potomac, but so changed in character, that the stranger, who from the Capitol had traced the mazy windings of this mighty stream, whose deep indents and sluggish current show like a series of lakes stretching away till lost in distance, suddenly removed to this point, short of two miles, would hardly credit that the narrow, noisy mountain stream beside him was the same, the very fountain and feeder of the inland sea spreading below. It was now dry, fine weather; no rain had fallen for some time; and the stream, pent within narrow limits, cowered beneath the wooded heights of the Virginia shore: but the condition of every unprotected level on our side spoke awfully of its force, when, backed by supplies from the mountains, it extends itself abroad, overthrowing trees and banks, and leaving their huge ruins to mark in undoubted characters the true limit of its sovereignty. At this time it was in its most peaceful mood, and went on, now expanding placidly over an even bed, and now divided before some stubborn rock-founded islet, chafing as it were at being compelled to yield to an obstruction it had as yet failed to overcome. Viewed at all points, the stream conducted by Nature outfaced, in my eyes, the neighbour work of her children; coursing onward, as it went, defying the hand of man, and rejoicing in its rude freedom. About the most savage part of our ride, where the path was a wide rampart of stone without any parapet, bounded on one hand by the canal and the overhanging rocks through which it was cut, and on the other, at a precipitous depth of eighty feet, by the rocky bed of the river, we were threatened with a hurricane, or other outbreak of the elements, of the wildest kind. It had become on a sudden unnaturally sultry: before us a cloud fell like a huge black curtain, until resting upon the lofty bluffs between which the river now ran, it was draped in folds down to the water; over this curtain broke a lurid silvery sort of light, making all things hideous; a heavy moaning sound as of wind was heard throughout the forest; the leaves shook rattling upon the surrounding shrubs, yet no air was perceptible even whilst going at a gallop. For a moment this strange sound would cease wholly, and then roar forth again, as though the pent tempest was striving close at hand for space and freedom of action. Occasionally a vivid flash of lightning would stream from the impending cloud downward upon the river; and, in momentary expectation of a regular tornado, on we spurred to reach some shelter. But after all, our fears were fruitless, or let me rather say our hopes, since we agreed that a hurricane chancing here would be a consummation singularly happy. It is certain no fitter scene could well have been selected for such an event, and indeed this was all that was needed to make the savage grandeur of the picture perfect.
