Tuesday May 21st 1805 A delightfull morning set out at an early hour and proceeded on very well, imployed the chord principally; the shores are abbrupt and bould and composed of a black and yellow clay; see no extensive collection of pure sand, the bars are composed black mud and a small poportion of fine sand; the courant still pretty strong. the Missouri in it's course downward makes a suddon and extensive bend to receive the Muscle shell river, the point of country thus formed tho high is still much lower than that surrounding it, thus forming a valley of wavey country which extends itself for a great distance in a Northerly direction; the soil is fertile, produces a fine turf of low grass and some herbs, also immence quantities of the Prickley pear, without a stick of timber of any discription. the country on the South side is high broken and crowned with some scrubby pines and dwarf cedar; the leaf of this pine is much longer than the common pitch or red pine of Virginia, the cone is also longer and slimer, and the imbrications wider and thicker, and the whole frequently covered with rosin. Mineral appearances as usual. the growse or praire hen are now less abundant on the river than they were below; perhaps they betake themselves to the open plains at a distance from the river at this season.-
The wind which was moderate all the fore part of the day continued to encrease in the evening, and about dark veered about to N. W. and blew a storm all night, in short we found ourselves so invelloped with clouds of dust and sand that we could neither cook, eat, nor sleep; and were finally compelled to remove our lodge about eight oClock at night to the foot of an adjacent hill where we were covered in some measure from the wind by the hills. several loose articles blown over board and lost. our first station was on a bar on Stard. opposite the lower point of a small Island, which we now called windy Island. the bends of the river are short and suddon, the points covered with some cottonwood, larger willow, or broadleafed willow with an abundance of the wild rose and some small honeysuckle bushes constitute the undergrowth, the redwood is also found in small quantities. Capt. C walked on shore today and killed 2 Elk; the party killed several deer and a buffaloe Cow.-
