Another of our excursions was to Harper's Ferry,--the Directors of the Baltimore and Ohio Railroad having kindly invited us to accompany them on the first trip over the newly laid track, after its breaking up by the Rebels. It began to rain, in the early morning, pretty soon after we left Washington, and continued to pour a cataract throughout the day; so that the aspect of the country was dreary, where it would otherwise have been delightful, as we entered among the hill-scenery that is formed by the subsiding swells of the Alleghanies. The latter part of our journey lay along the shore of the Potomac, in its upper course, where the margin of that noble river is bordered by gray, overhanging crags, beneath which--and sometimes right through them--the railroad takes its way. In one place the Rebels had attempted to arrest a train by precipitating an immense mass of rock down upon the track, by the side of which it still lay, deeply imbedded in the ground, and looking as if it might have lain there since the Deluge. The scenery grew even more picturesque as we proceeded, the bluffs becoming very bold in their descent upon the river, which, at Harper's Ferry, presents as striking a vista among the hills as a painter could desire to see. But a beautiful landscape is a luxury, and luxuries are thrown away amid discomfort; and when we alighted into the tenacious mud and almost fathomless puddle, on the hither side of the Ferry, (the ultimate point to which the cars proceeded, since the railroad bridge had been destroyed by the Rebels,) I cannot remember that any very rapturous emotions were awakened by the scenery. We paddled and floundered over the ruins of the track, and, scrambling down an embankment, crossed the Potomac by a pontoon-bridge, a thousand feet in length, over the narrow line of which--level with the river, and rising and subsiding with it--General Banks had recently led his whole army, with its ponderous artillery and heavily laden wagons. Yet our own tread made it vibrate. The broken bridge of the railroad was a little below us, and at the base of one of its massive piers, in the rocky bed of the river, lay a locomotive, which the Rebels had precipitated there.
