Rock Bridges occupy the same pre-eminence amongst the sublimities of nature, that artificial bridges maintain amidst the labours of man. Both alike inspire us with admiration, though we are enabled to obtain but unequal results as to their respective origins. The bridge, built by human hands, is, indeed, a triumph of the perfection of skilful contrivance; the strength and beauty of the arch are among the most simple yet exquisite results of science, wonderful as they may appear to the untaught beholder: but how shall we explain the formation of stupendous rock-arches across deep ravines and rolling torrents, in countries where none but the wild and picturesque forms of nature rise to gladden the eye and heart of the inquiring traveller? Of the latter description are the natural bridges which abound in the State of Virginia; as Rockbridge, which gives name to the county in which it is situated, and the wild and fantastic bridges of Icognozo; all of which are more extensively recognised among the wonders of creation than the specimen here presented to the reader.
This Tunnel is in Scott county, Virginia; but was so little known beyond its immediate neighbourhood, as to induce Lieut.-Col. Long, (U.S. Army,) to communicate its description to Mr. Featherstonhaugh's American Journal of Geology and Natural Science; and the following narrative of the Colonel's Excursion will be read with interest:—

"Saturday, Aug. 13, 1831. Having ascended Cove ridge, we turned aside from our route to visit the natural bridge, or tunnel, situated on Buck-eye, or Stock creek, about a mile below the Sycamore camp,2 and about one and a half miles from a place called Rye cove, which occupies a spacious recess between two prominent spurs of Powell's mountain, the site of the natural tunnel being included within a spur of Cove ridge, which is one of the mountain spurs just alluded to. Here is presented one of the most remarkable and attractive curiosities of its kind, to be witnessed in this or any other country. The creek, which is about seven yards wide, and has a general course about S. 15 W., here passes through a hill elevated from two to three hundred feet above the surface of the stream, winding its way through a huge subterraneous cavern, or grotto, whose roof is vaulted in a peculiar manner, and rises from thirty to seventy or eighty feet above its floor. The sides of this gigantic cavern rise perpendicularly in some places to the height of fifteen or twenty feet, and, in others, are formed, by the springing of its vaulted roof immediately from its floor. The width of the tunnel varies from fifty to one hundred and fifty feet. Its course is that of a continuous curve, resembling the letter S; first winding to the right as we enter on the upper side, then to the left, again to the right, and then again to the left on arriving at the entrance on the lower side. Such is its peculiar form, that an observer, standing at a point about midway of its subterranean course, is completely excluded from a view of either entrance, and is left to grope in the dark through a distance of about twenty yards, occupying an intermediate portion of the tunnel. When the sun is near the meridian, and his rays fall upon both entrances, the light reflected from both extremities of the tunnel contributes to mollify the darkness of this interior portion into a dusky twilight.
