and into the deepest coverts, and the wild ducks were shooting past in
long lines, piercing the thick air with outstretched neck and clanging
wing.

Suddenly the wind fell, and the sound of the waterfall increased, and
grew rough and loud, and the undefinable rushing noise that precedes a
heavy fall of rain in the tropics, the voice of the wilderness, moaned
through the high woods, until at length the clouds sank upon the valley
in boiling mists, rolling halfway down the surrounding hills; and the
water of the stream, whose scanty rill but an instant before hissed over
the precipice in a small, transparent ribbon of clear grass-green,
sprinkled with white foam, and then threaded its way round the large
rocks in its capacious channel, like a silver eel twisting through a
desert, now changed in a moment to a dark turgid chocolate colour; and
even as we stood and looked, lo! a column of water from the mountains,
pitched in thunder over the face of the precipice, making the earth
tremble, and driving up from the rugged face of the everlasting rocks in
smoke, and forcing the air into eddies and sudden blasts which tossed
the branches of the trees that overhung it, as they were dimly seen
through clouds of drizzle, as if they had been shaken by a tempest,
although there was not a breath stirring elsewhere out of heaven; while
little, wavering, spiral wreaths of mist rose up thick from the surface
of the boiling pool at the bottom of the cataract, like miniature
water-spouts, until they were dispersed by the agitation of the air
above.

filling the whole water-course, about fifty yards wide, and advancing
with a solid front a fathom _high_--a fathom _deep_ does not
convey the idea--like a stream of lava, or as one may conceive of the
