a fine morning Set out verry early, the murcery Stood 56° above 0. proceeded on to the mouth of the Little Missouri river and formed a Camp in a butifull elivated plain on the lower Side for the purpose of takeing Some observations to fix the Latitude & Longitude of this river. this river falls in on the L. Side and is 134 yards wide and 2 feet 6 Inches deep at the mouth, it takes its rise in the N W extremity of the black mountains, and through a broken countrey in its whole course washing the N W base of the Turtle Mountain which is Situated about 6 Leagues S W of its mouth, one of our men Baptiest who came down this river in a canoe informs me that it is not navagable, he was 45 days descending.

One of our men Shot a beaver Swimming below the mouth of this river.

I walked out on the lower Side of this river and found the countrey hilley the Soil composed of black mole & a Small perportion of Sand containing great quantity of Small peable Some limestone, black flint, & Sand Stone I killed a Hare Changeing its Colour Some parts retaining its long white fur & other parts assumeing the Short grey, I Saw the Magpie in pars, flocks of Grouse, the old field lark & Crows, & observed the leaf of the wild Chery half grown, many flowers are to be seen in the plains, remains of Minetarra & Ossinneboin hunting Camps are to be Seen on each Side of the two Missouris

The wind blew verry hard from the S. all the after part of the day, at 3 oClock P M. it became violent & flowey accompanied with thunder and a little rain. We examined our canoes &c found Several mice which had already commenced cutting our bags of corn & parched meal, the water of the little Missouri is of the Same texture Colour & quallity of that of the Big Missouri the after part of the day so Cloudy that we lost the evening observation.
