lleys, which extend themselves for a considerable distance towards the
north. These appearances of vegetation are delightful after the dreary
hills among which we have passed; and we have now to congratulate
ourselves at having escaped from the last ridges of the Black Mountains.
On leaving Thompson's Creek we passed two small islands, and at
twenty-three miles' distance encamped among some timber; on the north,
opposite to a small creek, which we named Bull Creek. The bighorn are
in great quantities, and must bring forth their young at a very early
season, as they are now half grown. One of the party saw a large bear
also; but, being at a distance from the river, and having no timber to
conceal him, he would not venture to fire."

A curious adventure happened on the twenty-eighth, of which the journal,
next day, makes this mention:--

"Last night we were alarmed by a new sort of enemy. A buffalo swam over
from the opposite side, and to the spot where lay one of our canoes,
over which he clambered to the shore: then, taking fright, he ran full
speed up the bank towards our fires, and passed within eighteen inches
of the heads of some of the men before the sentinel could make him
change his course. Still more alarmed, he ran down between four fires,
and within a few inches of the heads of a second row of the men, and
would have broken into our lodge if the barking of the dog had not
stopped him. He suddenly turned to the right, and was out of sight in
a moment, leaving us all in confusion, every one seizing his rifle and
inquiring the cause of the alarm. On learning what had happened, we had
to rejoice at suffering no more injury than some damage to the guns that
were in the canoe which the buffalo crossed. . . .

"We passed an island and two sand-bars, and at the distance of two
and a half miles came to a handsome river, which discharges itself on
the South, and which we ascended to the distance of a mile and a half:
we called it Judith's River. It rises in the Rocky Mountains, in about
the same place with the Musselshell, and near the Yellowstone River. Its
entrance is one hundred yards wide from one bank to the other, the water
occupying about seventy-five yards, and being in greater quantity than
that of the Musselshell River. . . . There were great numbers of the
argalea, or bighorned animals, in the high country through which it
passes, and of beaver in its waters. Just above the entrance of it we
saw the ashes o
