This morning I waited at my camp very impatiently for the arrival of Capt. Clark and party; I observed by my watch that it was 7 A. M. and they had not come in sight. I now became very uneasy and determined to wait until 8 and if they did not arrive by that time to proceed on up the river taking it as a fact that they had passed my camp some miles last evening. just as I set out to pursue my plan I discovered Charbono walking up shore some distance below me and waited untill arrived I now learnt that the canoes were behind, they arrived shortly after. their detention had been caused by the rapidity of the water and the circuitous rout of the river. they halted and breakfasted after which we all set out again and I continued my walk on the Stard. shore the river now becomes more collected the islands tho' numerous ar generally small. the river continues rapid and is from 90 to 120 yd. wide has a considerable quantity of timber in it's bottoms. towards evening the bottoms became much narrower and the timber much more scant. high hills set in close on the Lard. and the plain high waivy or reather broken on the Stard. and approach the river closely for a shot distance vally above 1½ M wd. About one mile above Capt. Clark's encampment of the last evening the principall entrance of a considerable river discharges itself into Jefferson's river. this stream is a little upwards of 30 yd. wide discharges a large quantity of very clear water it's bed like that of Jefferson's river is pebble and gravel. it takes it's rise in the snowclad mountains between Jefferson's and Madison's Rivers to the S. W. and discharges itself into the former by seven mouths it has some timber in it's bottoms and vas numbers of beaver and Otter.  This stream we call River Philosophy.  the rock of the clifts this evening is a hard black grannite like that of the clifts of most parts of the river below the limestone clifts at the 3 forks of the Missouri.  this evening just before we encamped Drewyer discovered a brown bear enter a small cops of bushes on the Lard. side; we surrounded the place an surched the brush but he had escaped in some manner unperceived but how we could not discover. nothing killed today and our fresh meat is out. when we have a plenty of fresh meat I find it impossible to make the men take any care of it, or use it with the least frugallity. tho' I expect that necessity will shortly teach them this art. the mountains on both sides of the river at no great distance are very lofty. we have a lame crew just now, two with tumers or bad boils on various parts of them, one with a bad stone bruise, one with his arm accedently dislocated but fortunately well replaced, and a fifth has streigned his back by sliping and falling backwards on the gunwall of the canoe. the latter is Sergt. Gass. it gives him great pain to work in the canoe in his present situation, but he thinks he can walk with convenience, I therefore scelected him as one of the party to accompany me tomorrow, being determined to go in quest of the Snake Indians. I also directed Drewyer and Charbono to hold themselves in readiness. Charbono thinks that his ankle is sufficiently recovered to stand the march but I entertain my doubts of the fact; he is very anxious to accompany me and I therefore indulge him. There is some pine  on the hills on both sides of the river opposite to our encampment which is on the Lard. side upon a small island just above a run. the bull rush & Cat-tail flag  grow in great abundance in the moist parts of the bottoms the dryer situations are covered with fine grass, tanzy, thistles, onions and flax.  the bottom land fertile and of a black rich loam. the uplands poor sterile and of a light yellow clay with a mixture of small smooth pebble and gravel,  poducing prickley pears, sedge and the bearded grass in great abundance;  this grass is now so dry that it would birn like tinder.— we saw one bighorn  today as a few antelopes and deer.—

Wednesday 31st. We set out early, and had a fine cool morning with dew. Last night Capt. Lewis went on ahead, and the canoes being unable to get on to him, he was obliged to encamp out alone in this howling wilderness. We passed a small creek this morning on the south side, which empties into the river, through 2 or 3 mouths, on account of its being much dammed up by the beaver, which are very plenty. At breakfast time we came up to Capt. Lewis; and having made 17 miles and three quarters, encamped  on an island.

Wednesday July 31st About 10 o'Clock last night, the hunters that were out came to our Camp, and had left Captain Lewis, who staid out, all night, We had a fine morning and set out at sunrise; and proceeded on our Voyage; we found the current of the River running strong against us, we passed the Mouth of a large creek which lay on the South side of the River [erasure] which was damed up in many places by the Beaver, We passed also by low bottomed land, lying on both sides of the River, which was cover'd with small Cotton wood timber, Willows, &ca—. About 8 o'Clock A. M. we arrived at the place where Captain Lewis was & had encamped last night. We halted at this place and breakfasted. We then proceeded on, and passed a plain lying on the South side of the River. The hills near to this plain begin to make in near the River, on both sides of it. We also passed a very large Island, which lay low, and mostly Priari land, and but little Timber, on it; On the South side of the River opposite to this Island is a large open plain, having a handsome Creek,  running through it.— On this plaine we found growing, abundance of Wild flax, Tanzey, thistles & wild flowers, and had grass growing luxuriently on it, There was some timber likewise at this place which grew near the River. We dined at that place under a delightful grove of cotton timber, which lies a small distance from a Mountain; which had large heaps of Snow lying on it.— We proceeded on about One Mile when we passed hills, lying on both sides of the River, which keeps along under the mountains, Captain Clark saw a Mountain Sheep (or Ibex) with his spy Glass, on a round hill towards the Mountain; We found the Game getting very scarce, & we are now without fresh meat, which was very uncommon with us. This day proved very warm; We continued on our way, and passed clifts of Rocks, and high Walls of Stone lying along the Shores on both sides of the River.— We saw growing along the hills sides on each side of the River some scattering pine trees. We encamped in the Evening on a small Island, lying on the South side of the River, having came this day 17¾ Miles. Our hunters that were on Shore wounded a White or Brown bear, but it made its escape.
