July 9th 1806. Set out early and had not proceeded far before it began to rain. the air extreemly cold. halted a few minutes in some old lodges until it cased to rain in some measure. we then proceeded and it rained without intermission wet us to the skin.
N. 80° E. 4 ms. through a handsome level wide bottom in which there is a considerable quanty of narrow leafed cottonwood timber. the river is generally about 80 yds. wide rapid yet I think it migt be navigated. it's bed is loose gravel and pebbles. the banks low but seldom overflow. water clear.
S 85 E 4 ms Still on the S W. side of the river through wide and level bottoms some timber. Joseph feilds killed a very fat buffaloe bull and we halted to dine. we took the best of the meat as much as we could possibly carry on our horses. the day continuing rainy and cold I concluded to remain all day. we feasted on the buffaloe. saw a number of deer wolves and Antelopes. killed two deer.

July 10th 1806. Set out early and continued down the S W bank of the river N 75 E 24 m. to our encampment in a grove of cottonwood timber. the latter part of this course for 7 miles there is no timber in the river bottom, the other parts of the river possesses bottoms of the wide leafed cottonwood. much the greater part of the bottom is untimbered. the bottoms are wide and level the high praries or plains are also beautiful level and smooth. great quantities of prickly pear of two kinds on the plains. the ground is renderd so miry by the rain which fell yesterday that it is excessively fatiegueing to the horses to travel. we came 10 miles and halted for dinner the wind blowing down the river in the fore part of the day was unfavourable to the hunters they saw several gangs of Elk but they having the wind of them ran off. in the evening the wind set from the West and we fell in with a few elk of which R. Fields and myself killed 3 one of which swam the river and fell on the opposite so we therefore lost it's skin I sent the packhorses on with Sergt. Gass directing them to halt and encamp at the first timber which proved to be about 7 ms. I retained frazier to assist in skining the Elk. we wer about this time joined by drewer. a large brown bear swam the river near where we were and drewyer shot and killed it. by the time we butchered thes 2 elk and bar it was nearly dark we loaded our horses with the best of the meat and pursud the party and found them encamped as they had been directed in the first timber. we did not reach them until 9 P.M. they informed us that they had seen a very large bear in the plains which had pursued Sergt. Gass and Thomson some distance but their horses enabled them to keep out of it's reach. they were affraid to fire on the bear least their horses should throw them as they were unaccustomed to the gun. we killed five deer 3 Elk and a bear today saw vast herds of buffaloe in the evening below us on the river. we hered them bellowing about us all night. vast assemblages of wolves. saw a large herd of Elk making down the river. passed a considerable rapid in medicine river after dark. the river about a hundred yards wide is deep and in many parts rappid and today has been much crouded with islands. from our encampment down we know the river and there is no rapids and scarcely any courant. goosberries are very abundant of the common red kind and are begining to ripen. no currants on this river. both species of the prickly pears just in blume.

July 11th 1806. the morning was fair and the plains looked beatifull the grass much improved by the late rain. the air was pleasant and a vast assemblage of little birds which croud to the groves on the river sung most enchantingly. we set out early. I sent the hunters down Medicine river to hunt Elk and proceeded with the party across the plain to the white bear Islands which I found to be 8 ms. distant my course S. 75 E.- through a level beautiful) and extensive high plain covered with immence birds of buffaloe.—it is now the season at which the buffaloe begin to coppelate and the bulls keep a tremendious roaring we could hear them for many miles and there are such numbers of them that there is one continual roar. our horses had not been acquainted with the buffaloe they appeared much allarmed at their appearance and bellowing. when I arrived in sight of the whitebear Islands the missouri bottoms on both sides of the river were crouded with buffaloe I sincerely belief that there were not less than 10 thousand buffaloe within a circle of 2 miles arround that place. I met with the hunters at a little grove of timber opposite to the island where they had killed a cowl and were waiting our arrival. they had met with no elk. I directed the hunters to kill some buffaloe as well for the benifit of their skins to enable us to pass the river as for their meat for the men I meant to leave at this place. we unloaded our horses and encamped opposite to the Islands. had the cow skined and some willows sticks collected to make canoes of the hides by 12 OCk. they killed eleven buffaloe most of them in fine order. the bulls are now generally much fatter than the cows and are fine beef. I sent out all hands with the horses to assist in buthering and bringing in the meat by 3 in the evening we had brought in a large quantity of fine beef and as many hides as we wanted for canoes shelters and geer. I then set all hands to prepare two canoes the one we made after the mandan fassion with a single skin in the form of a bason and the other we constructed of two skins on a plan of our own. we were unable to compleat our canoes this evening. the wind blew very hard. we continued our operations untill dark and then retired to rest. I intend giving my horses a couple of days rest at this place and deposit all my baggage which is not necessary to my voyage up medicine river.
