At last you come to a lofty subterraneous dome, lit from above by a cleft in the mountain; while full before you, in the opposite wall, from a low, black arch, midway up, and inaccessible, the stream, with a hollow ring and a dash, falls in a long, snowy column into a bottomless pool, whence, after many an eddy and whirl, it entered the flume, and away with a rush. ”
