of elk on a small island, where we halted and in a short time
killed fifteen of them. We took the skins and the best parts
of the meat, and proceeded. At noon we halted to dine, and
had then a very heavy shower of rain. We also killed another
of the large horned animals or mountain sheep.—We remained
here about an hour, then proceeded on, and will soon be clear
of this range of high rough country. In our way this after-
noon, we killed two mules and twelve other deer, and two
beaver. Though the afternoon was wet and disagreeable, we
came 70 miles to day.
