Tuesday, April 9. We set off as soon as it was light, and proceeded five miles to breakfast, passing a low ground on the south, covered with groves of cottonwood timber. At the distance of six miles, we reached on the north a hunting camp of Minnetarees consisting of thirty lodges, and built in the usual form of earth and timber. Two miles and a quarter farther, comes in on the same side Miry creek, a small stream about ten yards wide, which, rising in some lakes near the Mouse river, passes through beautiful level fertile plains without timber in a direction nearly southwest; the banks near its entrance being steep, and rugged on both sides of the Missouri. Three miles above this creek we came to a hunting party of Minnetarees, who had prepared a park or inclosure and were waiting the return of the antelope: this animal, which in the autumn retires for food and shelter to the Black mountains during the winter, recross the river at this season of the year, and spread themselves through the plains on the north of the Missouri. We halted and smoked a short time with them, and then proceeded on through handsome plains on each side of the river, and encamped at the distance of twenty-three and a half miles on the north side: the day was clear and pleasant, the wind high from the south, but afterwards changed to a western steady breeze. The bluffs which we passed to-day are upwards of one hundred feet high, composed of a mixture of yellow clay and sand, with many horizontal strata of carbonated wood resembling pit-coal, from one to five feet in depth, and scattered through the bluff at different elevations, some as high as eighty feet above the water: the hills along the river are broken, and present every appearance of having been burned at some former period; great quantities of pumicestone and lava or rather earth, which seems to have been boiled and then hardened by exposure, being seen in many parts of these hills where they are broken and washed down into gullies by the rain and melting snow. A great number of brants pass up the river: there are some of them perfectly white, except the large feathers of the first and second joint of the wing which are black, though in every other characteristic they resemble common gray brant: we also saw but could not procure an animal that burrows in the ground, and similar in every respect to the burrowing squirrel, except that it is only one third of its size. This may be the animal whose works we have often seen in the plains and prairies; they resemble the labours of the salamander in the sand hills of South Carolina and Georgia, and like him, the animals rarely come above ground; they consist of a little hillock of ten or twelve pounds of loose ground which would seem to have been reversed from a pot, though no aperture is seen through which it could have been thrown: on removing gently the earth, you discover that the soil has been broken in a circle of about an inch and a half diameter, where the ground is looser though still no opening is perceptible. When we stopped for dinner the squaw went out, and after penetrating with a sharp stick the holes of the mice, near some drift wood, brought to us a quantity of wild artichokes, which the mice collect and hoard in large numbers; the root is white, of an ovate form, from one to three inches long, and generally of the size of a man's finger, and two, four, and sometimes six roots are attached to a single stalk. Its flavour as well as the stalk which issues from it resemble those of the Jerusalem artichoke, except that the latter is much larger. A large beaver was caught in a trap last night, and the musquitoes begin to trouble us.

Wednesday 10. We again set off early with clear pleasant weather, and halted about ten for breakfast, above a sandbank which was falling in, and near a small willow island. On both sides of the Missouri, after ascending the hills near the water, one fertile unbroken plain extends itself as far as the eye can reach, without a solitary tree or shrub, except in moist situations or in the steep declivities of hills where they are sheltered from the ravages of fire. At the distance of twelve miles we reached the lower point of a bluff on the south; which is in some parts on fire and throws out quantities of smoke which has a strong sulphurous smell, the coal and other appearances in the bluffs being like those described yesterday: at one o'clock we overtook three Frenchmen who left the fort a few days before us, in order to make the first attempt on this river of hunting beaver, which they do by means of traps: their efforts promise to be successful for they have already caught twelve which are finer than any we have ever seen: they mean to accompany us as far as the Yellowstone river in order to obtain our protection against the Assiniboins who might attack them. In the evening we encamped on a willow point to the south opposite to a bluff, above which a small creek falls in, and just above a remarkable bend in the river to the southwest, which we called the Little Basin. The low grounds which we passed to-day possess more timber than is usual, and are wider: the current is moderate, at least not greater than that of the Ohio in high tides; the banks too fall in but little; so that the navigation comparatively with that lower down the Missouri is safe and easy. We were enabled to make eighteen and a half miles: we saw the track of a large white bear, there were also a herd of antelopes in the plains; the geese and swan are now feeding in considerable quantities on the young grass in the low prairies; we shot a prairie hen, and a bald eagle of which there were many nests in the tall cottonwood trees; but could procure neither of two elk which were in the plain. Our old companions the musquitoes have renewed their visit, and gave us much uneasiness.

Thursday, 11th. We set out at daylight, and after passing bare and barren hills on the south, and a plain covered with timber on the north, breakfasted at five miles distance: here we were regaled with a deer brought in by the hunters, which was very acceptable as we had been for several days without fresh meat; the country between this and fort Mandan being so frequently disturbed by hunters that the game has become scarce. We then proceeded with a gentle breeze from the south which carried the periogues on very well; the day was however so warm that several of the men worked with no clothes except round the waist, which is the less inconvenient as we are obliged to wade in some places owing to the shallowness of the river. At seven miles we reached a large sandbar making out from the north. We again stopped for dinner, after which we went on to a small plain on the north covered with cottonwood where we encamped, having made nineteen miles. The country around is much the same as that we passed yesterday: on the sides of the hills, and even on the banks of the rivers, as well as on the sandbars, is a white substance which appears in considerable quantities on the surface of the earth, and tastes like a mixture of common salt with glauber salts: many of the streams which come from the foot of the hills, are so strongly impregnated with this substance, that the water has an unpleasant taste and a purgative effect. A beaver was caught last night by one of the Frenchmen; we killed two geese, and saw some cranes, the largest bird of that kind common to the Missouri and Mississippi, and perfectly white except the large feathers on the two first joints of the wing which are black. Under a bluff opposite to our encampment we discovered some Indians with horses, whom we supposed were Minnetarees, but the width of the river prevented our speaking to them.

Friday, 12th. We set off early and passed a high range of hills on the south side, our periogues being obliged to go over to the south in order to avoid a sandbank which was rapidly falling in. At six miles we came to at the lower side of the entrance of the Little Missouri, where we remained during the day for the purpose of making celestial observations. This river empties itself on the south side of the Missouri, one thousand six hundred and ninety-three miles from its confluence with the Mississippi. It rises to the west of the Black mountains, across the northern extremity of which it finds a narrow rapid passage along high perpendicular banks, then seeks the Missouri in a northeastern direction, through a broken country with highlands bare of timber, and the low grounds particularly supplied with cottonwood, elm, small ash, box, alder, and an undergrowth of willow, redwood, sometimes called red or swamp-willow, the redberry and chokecherry. In its course it passes near the northwest side of the Turtle mountain, which is said to be only twelve or fifteen miles from its mouth in a straight line a little to the south of west, so that both the Little Missouri and Knife river have been laid down too far southwest. It enters the Missouri with a bold current, and is one hundred and thirty-four yards wide, but its greatest depth is two feet and a half, and this joined to its rapidity and its sandbars, make the navigation difficult except for canoes, which may ascend it for a considerable distance. At the mouth, and as far as we could discern from the hills between the two rivers about three miles from their junction, the country is much broken, the soil consisting of a deep rich dark coloured loam, intermixed with a small proportion of fine sand and covered generally with a short grass resembling blue grass. In its colour, the nature of its bed, and its general appearance, it resembles so much the Missouri as to induce a belief that the countries they water are similar in point of soil. From the Mandan villages to this place the country is hilly and irregular, with the same appearance of glauber salts and carbonated wood, the low grounds smooth, sandy, and partially covered with cottonwood and small ash; at some distance back there are extensive plains of a good soil, but without timber or water.

We found great quantities of small onions which grow single, the bulb of an oval form, white, about the size of a bullet with a leaf resembling that of the chive. On the side of a neighbouring hill, there is a species of dwarf cedar: it spreads its limbs along the surface of the earth, which it almost conceals by its closeness and thickness, and is sometimes covered by it, having always a number of roots on the under side, while on the upper are a quantity of shoots which with their leaves seldom rise higher than six or eight inches; it is an evergreen, its leaf more delicate than that of the common cedar, though the taste and smell is the same.

The country around has been so recently hunted that the game are extremely shy, so that a white rabbit, two beaver, a deer, and a bald eagle were all that we could procure. The weather had been clear, warm, and pleasant in the morning, but about three we had a squall of high wind and rain with some thunder, which lasted till after sunset when it again cleared off.

Saturday 13. We set out at sunrise, and at nine o'clock having the wind in our favour went on rapidly past a timbered low ground on the south, and a creek on the north at the distance of nine miles, which we called Onion creek, from the quantity of that plant which grows in the plains near it: this creek is about sixteen yards wide at a mile and a half above its mouth, it discharges more water than is usual for creeks of that size in this country, but the whole plain which it waters is totally destitute of timber. The Missouri itself widens very remarkably just above the junction with the Little Missouri: immediately at the entrance of the latter, it is not more than two hundred yards wide, and so shallow that it may be passed in canoes with setting poles, while a few miles above it is upwards of a mile in width: ten miles beyond Onion creek we came to another, discharging itself on the north in the centre of a deep bend: on ascending it for about a mile and a half, we found it to be the discharge of a pond or small lake, which seemed to have been once the bed of the Missouri: near this lake were the remains of forty-three temporary lodges which seem to belong to the Assiniboins, who are now on the river of the same name. A great number of swan and geese were also in it, and from this circumstance we named the creek Goose creek, and the lake by the same name: these geese we observe do not build their nests on the ground or in sandbars, but in the tops of lofty cottonwood trees: we saw some elk and buffaloe to-day but at too great a distance to obtain any of them, though a number of the carcases of the latter animal are strewed along the shores, having fallen through the ice, and been swept along when the river broke up. More bald eagles are seen on this part of the Missouri than we have previously met with; the small or common hawk, common in most parts of the United States, are also found here: great quantities of geese are feeding in the prairies, and one flock of white brant or goose with black wings, and some gray brant with them pass up river, and from their flight they seem to proceed much farther to the northwest. We killed two antelopes which were very lean, and caught last night two beaver: the French hunters who had procured seven, thinking the neighborhood of the Little Missouri a convenient hunting ground for that animal, remained behind there: in the evening we encamped in a beautiful plain on the north thirty feet above the river, having made twenty-two and a half miles.

Sunday 14. We set off early with pleasant and fair weather: a dog joined us, which we suppose had strayed from the Assiniboin camp on the lake. At two and a half miles we passed timbered low grounds and a small creek: in these low grounds are several uninhabited lodges built with the boughs of the elm, and the remains of two recent encampments, which from the hoops of small kegs found in them we judged could belong to Assiniboins only, as they are the only Missouri Indians who use spirituous liquors: of these they are so passionately fond that it forms their chief inducement to visit the British on the Assiniboin, to whom they barter for kegs of rum their dried and pounded meat, their grease, and the skins of large and small wolves, and small foxes. The dangerous exchange is transported to their camps with their friends and relations, and soon exhausted in brutal intoxication: so far from considering drunkenness as disgraceful, the women and children are permitted and invited to share in these excesses with their husbands and fathers, who boast how often their skill and industry as hunters has supplied them with the means of intoxication: in this, as in their other habits and customs, they resemble the Sioux from whom they are descended: the trade with the Assiniboins and Knistenaux is encouraged by the British, because it procures provision for their engages on their return from Rainy lake to the English river and the Athabasky country where they winter; these men being obliged during that voyage to pass rapidly through a country but scantily supplied with game. We halted for dinner near a large village of burrowing squirrels, who we observe generally select a southeasterly exposure, though they are sometimes found in the plains. At ten and a quarter miles we came to the lower point of an island, which from the day of our arrival there we called Sunday island: here the river washes the bases of the hills on both sides and above the island, which with its sandbar extends a mile and a half: two small creeks fall in from the south; the uppermost of these, which is the largest, we called Chaboneau's creek, after our interpreter who once encamped on it several weeks with a party of Indians. Beyond this no white man had ever been except two Frenchmen, one of whom Lapage is with us, and who having lost their way straggled a few miles further, though to what point we could not ascertain: about a mile and a half beyond this island we encamped on a point of woodland on the north, having made in all fourteen miles.

The Assiniboins have so recently left the river that game is scarce and shy. One of the hunters shot at an otter last evening; a buffaloe too was killed, and an elk, both so poor as to be almost unfit for use; two white bear were also seen, and a muskrat swimming across the river. The river continues wide and of about the same rapidity as the ordinary current of the Ohio. The low grounds are wide, the moister parts containing timber, the upland extremely broken, without wood, and in some places seem as if they had slipped down in masses of several acres in surface. The mineral appearances of salts, coal, and sulphur, with the burnt hill and pumicestone continue, and a bituminous water about the colour of strong lye, with the taste of glauber salts and a slight tincture of allum. Many geese were feeding in the prairies, and a number of magpies who build their nest much like those of the blackbird in trees, and composed of small sticks, leaves and grass, open at top: the egg is of a bluish brown color, freckled with reddish brown spots. We also killed a large hooting owl resembling that of the United States, except that it was more booted and clad with feathers. On the hills are many aromatic herbs, resembling in taste, smell and appearance the sage, hysop, wormwood, southern wood, juniper and dwarf cedar; a plant also about two or three feet high, similar to the camphor in smell and taste, and another plant of the same size, with a long, narrow, smooth, soft leaf, of an agreeable smell and flavour, which is a favourite food of the antelope, whose necks are often perfumed by rubbing against it.

Monday 15. We proceeded under a fine breeze from the south, and clear pleasant weather. At seven miles we reached the lower point of an island in a bend to the south, which is two miles in length. Captain Clarke, who went about nine miles northward from the river reached the high grounds, which, like those we have seen, are level plains without timber; here he observed a number of drains, which descending from the hills pursue a northeast course, and probably empty into the Mouse river, a branch of the Assiniboin, which from Indian accounts approaches very near to the Missouri at this place. Like all the rivulets of this neighbourhood these drains were so strongly impregnated with mineral salts that they are not fit to drink. He saw also the remains of several camps of Assiniboins; the low grounds on both sides of the river are extensive, rich, and level. In a little pond on the north, we heard for the first time this season the croaking of frogs, which exactly resembles that of the small frogs in the United States: there are also in these plains great quantities of geese, and many of the grouse, or prairie hen, as they are called by the N.W. company traders; the note of the male, as far as words can represent it, is cook, cook, cook, coo, coo, coo, the first part of which both male and female use when flying; the male too drums with his wings when he flies in the same way, though not so loud as the pheasant; they appear to be mating. Some deer, elk, and goats were in the low grounds, and buffaloe on the sand beaches, but they were uncommonly shy; we also saw a black bear, and two white ones. At fifteen miles we passed on the north side a small creek twenty yards wide, which we called Goatpen creek, from a park or enclosure for the purpose of catching that animal, which those who went up the creek found, and which we presume to have been left by the Assiniboins. Its water is impregnated with mineral salts, and the country through which it flows consists of wide and very fertile plains, but without any trees. We encamped at the distance of twenty-three miles, on a sandpoint to the south; we passed in the evening a rock in the middle of the river, the channel of which a little above our camp, is confined within eighty yards.
