This walk brings you into Pensico Avenue. Hitherto, the path has been rugged, wild, and rough, interrupted by steep acclivities, rocks, and big stones; but this avenue has a smooth and level floor, as if the sand had been spread out by gently flowing waters. Through this, descending more and more, you come to a deep arch, by which you enter the Winding Way; a strangely irregular and zig-zag path, so narrow that a very stout man could not squeeze through. In some places, the rocks at the sides are on a line with your shoulders, then piled high over your head; and then again you rise above, and overlook them all, and see them heaped behind you, like the mighty waves of the Red Sea, parted for the Israelites to pass through. This toilsome path was evidently made by a rushing, winding torrent. Toward the close, the water not having force enough to make a smooth bed, has bored a tunnel. This is so low and narrow, that the traveller is obliged to stoop and squeeze himself through. Suddenly he passes into a vast hall, called the Great Relief; and this leads into the River Hall, at the side of which you have a glimpse of a small cave, called the Smoke House, because it is hung with rocks perfectly in the shape of hams. The River Hall descends like the slope of a mountain. The ceiling stretches away--away--before you, vast and grand as the firmament at midnight. No one, who has never seen this cave, can imagine the excitement, and awe, with which the traveller keeps his eye fixed on the rocky ceiling, which, gradually revealed in the passing light, continually exhibits some new and unexpected feature of sublimity or beauty.
