Thursday April 25th 1805.
The wind was more moderate this morning, tho still hard; we set out at an early hour. the water friezed on the oars this morning as the men rowed. about 10 oclock A.M. the wind began to blow so violently that we were obliged to lye too. my dog had been absent during the last night, and I was fearfull we had lost him altogether, however, much to my satisfaction he joined us at 8 Oclock this morning. The wind had been so unfavorable to our progress for several days past, and seeing but little prospect of a favourable chang; knowing that the river was crooked, from the report of the hunters who were out yesterday, and beleiving that we were at no very great distance from the Yellow stone River; I determined, in order as mush as possible to avoid detention, to proceed by land with a few men to the entrance of that river and make the necessary observations to determine it's position, which I hoped to effect by the time that Capt. Clark could arrive with the party; accordingly I set out at 1 t OCk. on the Lard. side, accompanyed by four men. we proceeded about four miles, when falling in with some bufaloe I killed a yearling calf, which was in good order; we soon cooked and made a hearty meal of a part of it, and renewed our march our rout lay along the foot of the river hills. when we had proceeded about four miles, I ascended the hills from whence I had a most pleasing view of the country, perticularly of the wide and fertile values formed by the missouri and the yellowstone rivers, which occasionally unmasked by the wood on their borders disclose their meanderings for many miles in their passage through these delightfull tracts of country. I could not discover the junction of the rivers immediately, they being concealed by the woods, however, sensible that it could not be distant I determined to encamp on the bank of the Yellow stone river which made it's appearance about 2 miles South of me. the whol face of the country was covered with herds of Buffaloe, Elk & Antelopes; deer are also abundant, but keep themselves more concealed in the woodland. the buffaloe Elk and Antelope are so gentle that we pass near them while feeding, without apearing to excite any alarm among them, and when we attract their attention, they frequently approach us more nearly to discover what we are, and in some instances pursue us a considerable distance apparenly with that view.— in our way to the place I had determined to encamp, we met with two large herds of buffaloe, of which we killed three cows and a calf. two of the former, wer but lean, we therefore took their tongues and a part of their marrow-bones only. I then proceeded to the place of our encampment with two of the men, taking with us the Calf and marrowbones, while the other two remained, with orders to dress the cow that was in tolerable order, and hang the meat out of the reach of the wolves, a precaution indispensible to it's safe keeping, even for a night. we encamped on the bank of the yellowstone river, 2 miles South of it's confluence with the Missouri. On rejoining Capt. Clark, the 26th in the evening, he informed me, that at 5 P.M. after I left him the wind abated in some measure and he proceeded a few miles further and encamped.
25th of April Thursday 1805
The wind was moderate & ahead this morning, we Set out at an early hour The morning cold, Some flying Clouds to be Seen, the wind from the N. ice collected on the ores this morning, the wind increased and became So violent about 1 oClock we were obliged to lay by our Canoes haveing taken in Some water, the Dog which was lost yesterday, joined us this morning.
finding that the winds retarded our progression for maney days past, and no apparance of an alteration, and the river being Crooked that we could never have 3 miles fair wind, Capt. Lewis concluded to go by land as far as the Rochejhone or yellow Stone river, which we expect is at no great distance by land and make Some Selestial observations to find the Situation of its mouth, and by that measure not detain the Perogues at that place any time for the purpose of makeing those necessary observations he took 4 men & proceeded on up the Missouri on the L. Side, at 5 oClock the wind luled and we proceeded on and incamped.
