ployed in airing the baggage, dressing skins and hunting.
Capt. Clarke still continued unwell. Our squaw informed us,
that it was at this place she had been taken prisoner by the
Grossventers 4 or 5 years ago. From this valley we can dis-
cover a large mountain with snow on it, towards the south-
west; and expect to pass by the northwest end of it. Capt.
Lewis had a meridian altitude here, which gave 45 22 34 .5
north latitude. We also remained here the 29th, which was a
fine day, and the men chiefly employed in the same way.
Capt. Clarke is getting better.
