upon
which the bears turned, rose again upon their haunches, and repeated
their serio-comic examination. This was repeated several times, until
the hunters, piqued at their unmannerly staring, rebuked it with a
discharge of their rifles. The bears made an awkward bound or two, as
if wounded, and then walked off with great gravity, seeming to commune
together, and every now and then turning to take another look at the
hunters. It was well for the latter that the bears were but half grown,
and had not yet acquired the ferocity of their kind.

The buffalo were somewhat startled at the report of the firearms; but
the hunters succeeded in killing a couple of fine cows, and, having
secured the best of the meat, continued forward until some time after
dark, when, encamping in a large thicket of willows, they made a great
fire, roasted buffalo beef enough for half a score, disposed of the
whole of it with keen relish and high glee, and then "turned in" for the
night and slept soundly, like weary and well fed hunters.

At daylight they were in the saddle again, and skirted along the river,
passing through fresh grassy meadows, and a succession of beautiful
groves of willows and cotton-wood. Toward evening, Captain Bonneville
observed a smoke at a distance rising from among hills, directly in the
route he was pursuing. Apprehensive of some hostile band, he concealed
the horses in a thicket, and, accompanied by one of his men, crawled
cautiously up a height, from which he could overlook the scene of
danger. Here, with a spy-glass, he reconnoitred the surrounding
country, but not a lodge nor fire, not a man, horse, nor dog, was to be
discovered; in short, the smoke which had caused such alarm proved to
be the vapor from several warm, or rather hot springs of considerable
magnitude, pouring forth streams in every direction over a bottom of
white clay. One of the springs was about twenty-five yards in diameter,
and so deep that the water was of a bright green color.

They were now advancing diagonally upon the chain of Wind River
Mountains, which lay between them and Green River valley. To coast round
their southern points would be a wide circuit; whereas, could they
force their way through them, they might proceed in a straight line. The
mountains were lofty, with snowy peaks and cragged sides; it was hoped,
however, that some practicable defile might be found. They attempted,
accordingly, to penetrate the mountains by following
