 gloomily overhead, for we have dropped below the sandstone and have entered the archæan—a frowning black rock, streaked, veined, and swirled with vivid red and white, smoothed and polished by the rivulet and beautiful as a mosaic. Obstacles are encountered in the form of steep, interposing crags, past which the brook has found a way, but over which the pedestrian must clamber.

At every turn one looks to see the embouchure upon the river, anticipating the sudden shock of the unintercepted roar of waters. When at last this is reached, over a final downward clamber, the traveler stands upon a sandy rift confronted by nearly vertical walls many hundred feet high, at whose base a black torrent pitches in a giddying onward slide that gives him momentarily the sensation of slipping into an abyss.
