ses nearly perpendicular. Gabriel's horse was much
bruised, but after an hour's severe toil, we gained the bottom, without
sustaining any serious injury.

Here we remained a couple of hours, to rest our weary animals and find
the trail leading up the opposite side. This we discovered, and, after
great exertions, succeeded in clambering up to the top, where we again
found ourselves upon a smooth and level prairie. On looking backs I
shuddered to behold the frightful chasm we had so successfully passed,
and thought it a miracle that we had got safely across; but a very short
time afterwards, I was convinced that the feat we had just accomplished
was a mere nothing.

After giving our animals another rest, we resumed our journey across the
dreary prairie. Not a tree or bush could be seen in any direction. A
green carpeting of short grass was spread over the vast scene, with
naught else to relieve the sight.

People may talk of the solitude of forests as much as they please, but
there is a company in trees which one misses upon the prairie. It is in
the prairie, with its ocean-like waving of grass, like a vast sea
without landmarks, that the traveller feels a sickly sensation of
loneliness. There he feels as if not in the world, although not out of
it; there he finds no sign or trace to tell him that there are, beyond
or behind him, countries where millions of his own kindred are living
and moving. It is in the prairie that man really feels that he
is--alone.

We rode briskly along till sun-down, and encamped by the side of a small
water-hole, formed by a hollow in the prairie. The mustangs, as well as
the deer and antelopes, had left this part of the prairie, driven out,
doubtless, by the scarcity of water. Had it not been for occasional
showers, while travelling through this dreary waste, we should most
inevitably have perished, for even the immense chasms had no water in
them, except that temporarily supplied by the rains.

CHAPTER XXII.

The morning broke bright and cloudless, the sun rising from the horizon
in all his majesty. Having saddled our horses, we pursued our journey in
a north-east direction; but we had scarcely proceeded six miles before
we suddenly came upon an immense rent or chasm in the earth, far
exceeding in depth the one we had so much difficulty in crossing the day
before. We were not aware of its existence until we were immediately
upon its brink, when a spectacle exceeding in grandeur
