April 10, 1792. The weather was now again most delicious, and revived our spirits exceedingly. The sun began to have power, and the river was quite free of ice, so the Indians assured us, for a hundred miles ahead. We bade adieu to Little Snake (a chief of the Ricarees who had shown the voyagers many evidences of friendship during the winter] and his band, with unfeigned regret, and set out, after breakfast, on our voyage. Perrine [an agent of the Hudson Bay fur company on his way to Petite Cote) accompanied us with three Indians for the first ten miles, when he took leave of us and made his way back to the village, where (as we afterwards heard) he met with a violent death from the hands of a squaw, to whom he offered some insult. Upon parting with the agent, we pushed on vigorously up the river, and made great way, notwithstanding a rapid current. In the afternoon, Thornton, who had been complaining for some days past, was taken seriously ill; so much so that I urged the return of the whole party to the hut, there to wait until he should get better; but he resisted this offer so strongly that I was forced to yield. We made him a comfortable bed in the cabin, and paid him every attention; but he had a raging fever, with occasional delirium, and I was much afraid that we should lose him. In the meantime we still pushed ahead with resolution, and by night had made twenty miles — an excellent day's work.

April 11. Still beautiful weather. We started early, and had a good wind, which aided us greatly; so that, but for Thornton's illness, we should all have been in fine spirits. He seemed to grow much worse, and I scarcely knew how to act. Every thing was done for his comfort which could be done; Jules, the Canadian, made him some tea, from prairie herbs, which had the effect of inducing perspiration, and allayed the fever very sensibly. We stopped at night on the main land to the north, and three hunters went out into the prairie by moonlight, returning at one in the morning, without their rifles, and with a fat antelope.

They related that, having proceeded many miles across the country, they reached the banks of a beautiful rivulet, where they were much surprised and alarmed at discovering a large war-party of the Saonie Sioux, who immediately took them prisoners, and carried them a mile on the other side of the stream to a kind of park, or enclosure, walled with mud and sticks, in which was a large herd of antelopes. These animals were still coming into the park, the gates of which were so contrived as to prevent escape. This was an annual practice of the Indians. In the autumn, the antelopes retire for food and shelter from the prairie to the mountainous regions on the south of the river. In the spring they re-cross it in great numbers, and are then easily taken by being enticed into a strong enclosure as above described.

The hunters, (John Greely, the Prophet, and a Canadian) had scarcely any hope of escape from the clutches of the Indians, (who numbered as many as fifty,) and had well nigh made up their minds to die. Greely and the Prophet were disarmed and tied hand and foot; the Canadian, however, was suffered, for some reason not perfectly understood, to remain unbound, and was only deprived of his rifle, the savages leaving him in possession of his hunter's knife, (which, possibly they did not perceive, as it was worn in a sort of sheath in the side of his legging) and treating him otherwise with a marked difference from their demeanor to the others. This circumstance proved the source of the party's deliverance.

It was, perhaps, nine o'clock at night when they were first taken. The moon was bright, but, as the air was unusually cool for the season, the savages had kindled two large fires at a sufficient distance from the park not to frighten the antelopes, who were still pouring into it continually. At these fires they were occupied in cooking their game when the hunters so unexpectedly came upon them from round a clump of trees. Greely and the Prophet, after being disarmed and bound with strong thongs of buffalo hide, were thrown down under a tree at some distance from the blaze; while the Canadian was permitted to seat himself, in charge of two savages, by one of the fires, the rest of the Indians forming a circle round the other and larger one. In this arrangement, the time wore away slowly, and the hunters were in momentary expectation of death; the cords of the two who were bound caused them, also, infinite pain, from the tightness with which they were fastened. The Canadian had endeavored to hold a conversation with his guards, in the hope of bribing them to release him, but could not make himself understood. About midnight, the congregation around the large fire were suddenly disturbed by the dash of several large antelopes in succession through the midst of the blaze. These animals had burst through a portion of the mud wall which confined them, and, mad with rage and affright, had made for the light of the fire, as is the habit of insects at night in like circumstances. It seems, however, that the Saonies had never heard of any similar feat of these usually timid creatures, for they were in great terror at the unexpected interruption, and their alarm increased to perfect dismay, as the whole captured herd came rushing and bounding upon them, after the lapse of a minute or so from the outbreak of the first few. The hunters described the scene as one of the most singular nature. The beasts were apparently frantic, and the velocity and impetuosity with which they flew, rather than leaped, through the flames, and through the midst of the terrified savages, was said by Greely (a man not in the least prone to exaggerate) to have been not only an imposing but even a terrible spectacle. They carried every thing before them in their first plunges; but, having cleared the large fire, they immediately dashed at the small one, scattering the brands and blazing wood about; then returned, as if bewildered, to the large one, and so backwards and forwards until the decline of the fires, when, in small parties, they scampered off like lightning to the woods.

Many of the Indians were knocked down in this furious melee, and there is no doubt that some of them were seriously, if not mortally, wounded by the sharp hoofs of the agile antelopes. Some threw themselves flat on the ground, and so avoided injury. The Prophet and Greely, not being near the fires, were in no danger. The Canadian was prostrated at the first onset by a kick which rendered him senseless for some minutes. When he came to himself he was nearly in darkness; for the moon had gone behind a heavy thundercloud, and the fires were almost out, or only existed in brands scattered hither and thither. He saw no Indians near him, and instantly arousing himself to escape, made, as well as he could, for the tree where his two comrades were lying. Their thongs were soon cut, and the three set off at full speed in the direction of the river, without stopping to think of their rifles, or of any thing beyond present security. Having run for some miles, and finding no one in pursuit, they slackened their pace, and made their way to a spring for a draught of water. Here it was they met with the antelope which, as I mentioned before, they brought with them to the boats. The poor creature lay panting, and unable to move, by the border of the spring. One of its legs was broken, and it bore evident traces of fire. It was no doubt one of the herd which had been the means of deliverance. Had there been even a chance of its recovery the hunters would have spared it in token of their gratitude, but it was miserably injured, so they put it at once out of its misery, and brought it home to the boats, where we made an excellent breakfast upon it next morning.

April 12, 13, 14, and 15. During these four days we kept on our course without any adventure of note. The weather was very pleasant during the middle of the day, but the nights and mornings were exceedingly cold, and we had sharp frosts. Game was abundant. Thornton still continued ill, and his sickness perplexed and grieved me beyond measure. I missed his society very much, and now found that he was almost the only member of our party in whom I could strictly confide. By this I merely mean that he was almost the only one to whom I could, or would, freely unburthen my heart, with all its wild hopes, and fantastic wishes — not that any individual among us was unworthy of implicit faith. On the contrary, we were all like brothers, and a dispute, of any importance, never occurred. One interest seemed to bind all; or rather we appeared to be a band of voyagers without interest in view — mere travellers for pleasure. What ideas the Canadians might have held upon this subject I cannot, indeed, exactly say. These fellows talked a great deal, to be sure, about the profits of the enterprise, and especially about their expected share of it; yet I can scarcely think they cared much for these points, for they were the most simple-minded, and certainly the most obliging set of beings upon the face of the earth. As for the rest of the crew, I have no doubt in the world that the pecuniary benefit to be afforded by the expedition was the last thing upon which they speculated. Some singular evidences of the feeling which more or less pervaded us all occurred during the prosecution of the voyage. Interests, which, in the settlements, would have been looked upon as of the highest importance, were here treated as matters unworthy of a serious word, and neglected, or totally discarded upon the most frivolous pretext. Men who had travelled thousands of miles through a howling wilderness, beset by horrible dangers, and enduring the most heart-rending privations for the ostensible purpose of collecting peltries, would seldom take the trouble to secure them when obtained, and would leave behind them without a sigh an entire cache of fine beaver skin rather than forego the pleasure of pushing up some romantic-looking river, or penetrating into some craggy and dangerous cavern, for minerals whose use they knew nothing about, and which they threw aside as lumber at the first decent opportunity.

In all this my own heart was very much with the rest of the party; and I am free to say that, as we proceeded on our journey, I found myself less and less interested in the main business of the expedition, and more and more willing to turn aside in pursuit of idle amusement — if indeed I am right in calling by so feeble a name as amusement that deep and most intense excitement with which I surveyed the wonders and majestic beauties of the wilderness. No sooner had I examined one region than I was possessed with an irresistible desire to push forward and explore another. As yet, however, I felt as if in too close proximity to the settlements for the full enjoyment of my burning love of Nature, and of the unknown. I could not help being aware that some civilized footsteps, although few, had preceded me in my journey — that some eyes before mine own had been enraptured with the scenes around me. But for this sentiment, ever obtruding itself, I should no doubt have loitered more frequently on the way, turning aside to survey the features of the region bordering upon the river, and perhaps penetrating deeply, at times, into the heart of the country to the north and south of our route. But I was anxious to go on — to get, if possible, beyond the extreme bounds of civilization — to gaze, if I could, upon those gigantic mountains of which the existence had been made known to us only by the vague accounts of the Indians. These ulterior hopes and views I communicated fully to no one of our party save Thornton. He participated in all my most visionary projects, and entered completely into the spirit of romantic enterprise which pervaded my soul. I therefore felt his illness as a bitter evil. He grew worse daily, while it was out of our power to render him any effectual assistance.

April 16. To-day we had a cold rain with a high wind from the north, obliging us to come to anchor until late in the afternoon. At four o'clock, P. M., we proceeded, and made five miles by night. Thornton was much worse.

April 17, and 18. During both these days we had a continuance of raw unpleasant weather, with the same cold wind from the north. We observed many large masses of ice in the river, which was much swollen and very muddy. The time passed unpleasantly, and we made no way. Thornton appeared to be dying, and I now resolved to encamp at the first convenient spot, and remain until his illness should terminate. We accordingly, at noon this day, drew the boats up a large creek coming in from the south, and formed an encampment on the main land.

April 25. We remained at the creek until this morning, when, to the great joy of us all, Thornton was sufficiently recovered to go on. The weather was fine, and we proceeded gaily through a most lovely portion of the country, without encountering a single Indian, or meeting with any adventure out of the usual course until the last of the month, when we reached the country of the Mandans, or rather of the Mandans, the Minnetarees, and the Ahnahaways; for these three tribes all live in the near vicinity of each other, occupying five villages. Not a great many years ago the Mandans were settled in nine villages, about eighty miles below, the ruins of which we passed without knowing what they were — seven on the west and two on the east of the river; but they were thinned off by the small-pox and their old enemies the Sioux, until reduced to a mere handful, when they ascended to their present position. [Mr. R. gives here a tolerably full account of the Minnetarees and Ahnahaways or Wassatoons; but we omit it, as differing in no important particular from the ordinary statements respecting these nations.] The Mandans received us with perfect friendliness, and we remained in their neighborhood three days, during which we overhauled and repaired the piroque, and otherwise refitted. We also obtained a good supply of a hard corn, of a mixed color, which the savages had preserved through the winter in holes, near the front of their lodges. While with the Mandans we were visited by a Minnetaree chief, called Waukerassah, who behaved with much civility, and was of service to us in many respects. The son of this chief we engaged to accompany us as interpreter as far as the great fork. We made the father several presents, with which he was greatly pleased. * On the first of May we bade adieu to the Mandans, and went on our way.

The chief Waukerassah is mentioned by Captains Lewis and Clarke, whom he also visited.

May 1. The weather was mild, and the surrounding country began to assume a lovely appearance with the opening vegetation, which was now much advanced. The cotton-wood leaves were quite as large as a crown, and many flowers were full blown. The low grounds began to spread out here more than usual, and were well supplied with timber. The cotton-wood and common willow, as well as red willow, abounded; with rose-bushes in great plenty. Beyond the low grounds on the river, the country extended in one immense plain without wood of any kind. The soil was remarkably rich. The game was more abundant than we had ever yet seen it. We kept a hunter ahead of us on each bank, and to-day they brought in an elk, a goat, five beavers, and a great number of plovers. The beavers were very tame and easily taken. This animal is quite a bonne bouche as an article of food; especially the tail, which is of a somewhat glutinous nature, like the fins of the halibut. A beaver tall will suffice for a plentiful dinner for three men. We made twenty miles before night.

May 2. We had a fine wind this morning, and used our sails until noon, when it became rather too much for us, and we stopped for the day. Our hunters went out and shortly returned with an immense elk, whom Neptune had pulled down after a long chase, the animal having been only slightly wounded by a buck shot. He measured six feet in height. An antelope was also caught about dusk. As soon as the creature saw our men, it flew off with the greatest velocity, but after a few minutes stopped, and returned on its steps, apparently through curiosity — then bounded away again. This conduct was repeated frequently, each time the game coming nearer and nearer, until at length it ventured within rifle distance, when a shot from the Prophet brought it down. It was lean and with young. These animals, although of incredible swiftness of foot, are still bad swimmers, and thus frequently fall a victim to the wolves, in their attempts to cross a stream. Today made twelve miles.

May 3. This morning we made great headway, and by night had accomplished full thirty miles. The game continued to be abundant. Buffaloes, in vast numbers, lay dead along the shore, and we saw many wolves devouring the carcases. They fled always at our approach. We were much at a loss to account for the death of the buffaloes, but some weeks afterwards the mystery was cleared up. Arriving at a pass of the river where the bluffs were steep and the water deep at their base, we observed a large herd of the huge beasts swimming across, and stopped to watch their motions. They came in a sidelong manner down the current, and had apparently entered the water from a gorge, about half a mile above, where the bank sloped into the stream. Upon reaching the land on the west side of the river they found it impossible to ascend the cliffs, and the water was beyond their depth. After struggling for some time, and endeavoring in vain to get a foothold in the steep and slippery clay, they turned and swam to the eastern shore, where the same kind of inaccessible precipices presented themselves, and where the ineffectual struggle to ascend was repeated. They now turned a second time, a third, a fourth, and a fifth — always making the shore at very nearly the same places. Instead of suffering themselves to go down with the current in search of a more favorable landing, (which might have been found a quarter of a mile below), they seemed bent upon maintaining their position, and, for this purpose, swam with their breasts at an acute angle to the stream and used violent exertions to prevent being borne down. At the fifth time of crossing, the poor beasts were so entirely exhausted that it was evident they could do no more. They now struggled fearfully to scramble up the bank, and one or two of them had nearly succeeded, when, to our great distress (for we could not witness their noble efforts without commisseration) the whole mass of loose earth above caved in, and buried several of them in its fall, without leaving the cliff in better condition for ascent. Upon this the rest of the herd commenced a lamentable kind of lowing or moaning — a sound conveying more of a dismal sorrow and despair than any thing which it is possible to imagine — I shall never get it out of my head. Some of the beasts made another attempt to swim the river, struggled a few minutes, and sank — the waves above them being dyed with the red blood that gushed from their nostrils in the death agony. But the greater part, after the moaning described, seemed to yield supinely to their fate, rolled over on their backs, and disappeared. The whole herd were drowned — not a buffalo escaped. Their carcases were thrown up in half an hour afterwards upon the flat grounds a short distance below, where, but for their ignorant obstinacy, they might so easily have landed in safety.

May 4. The weather was delightful, and, with a fair warm wind from the south, we made twenty-five miles before night. To-day Thornton was sufficiently recovered to assist in the duties of the boat. In the afternoon he went out with me into the prairie on the west, where we saw a great number of early spring flowers of a kind never seen in the settlements. Many of them were of a rare beauty and delicious perfume. We saw also game in great variety, but shot none, as we were sure the hunters would bring in more than was wanted for use, and I was averse to the wanton destruction of life. On our way home we came upon two Indians of the Assiniboin nation, who accompanied us to the boats. They had evinced nothing like distrust on the way, but, on the contrary, had been frank and bold in demeanor; we were therefore much surprised to see them, upon coming within a stone's throw of the piroque, turn, both of them, suddenly round, and make off into the prairie at full speed. Upon getting a good distance from us, they stopped and ascended a knoll which commanded a view of the river. Here they lay on their bellies, and, resting their chins on their hands, seemed to regard us with the deepest astonishment. By the aid of a spy-glass I could minutely observe their countenances, which bore evidence of both amazement and terror. They continued watching us for a long time. At length, as if struck with a sudden thought, they arose hurriedly and commenced a rapid flight in the direction from which we had seen them issue at first.

May 5. As we were getting under way very early this morning, a large party of Assiniboins suddenly rushed upon the boats, and succeeded in taking possession of the piroque before we could make any effectual resistance. No one was in it at the time except Jules, who escaped by throwing himself into the river, and swimming to the large boat, which we had pushed out into the stream. These Indians had been brought upon us by the two who had visited us the day before, and the party must have approached us in the most stealthy manner imaginable, as we had our sentries regularly posted, and even Neptune failed to give any token of their vicinity.

We were preparing to fire upon the enemy when Misquash (the new interpreter — son of Waukerassah) gave us to understand that the Assiniboins were friends and were now making signals of amity. Although we could not help thinking that the highway robbery of our boat was but an indifferent way of evincing friendship, still we were willing to see what these people had to say, and desired Misquash to ask them why they had behaved as they did. They replied with many protestations of regard; and we at length found that they really had no intention of molesting us any farther than to satisfy an ardent curiosity which consumed them, and which they now entreated us to appease. It appeared that the two Indians of the day before, whose singular conduct had so surprised us, had been struck with sudden amazement at the sooty appearance of our negro, Toby. They had never before seen or heard of a blackamoor, and it must therefore be confessed that their astonishment was not altogether causeless. Toby, moreover, was as ugly an old gentleman as ever spoke — having all the peculiar features of his race; the swollen lips, large white protruding eyes, flat nose, long ears, double head, pot-belly, and bow legs. Upon relating their adventure to their companions, the two savages could obtain no credit for the wonderful story, and were about losing caste for ever, as liars and double-dealers, when they proposed to conduct the whole band to the boats by way of vindicating their veracity. The sudden attack seemed to have been the mere result of impatience on the part of the still incredulous Assiniboins; for they never afterwards evinced the slightest hostility, and yielded up the piroque as soon as we made them understand that we would let them have a good look at old Toby. The latter personage took the matter as a very good joke, and went ashore at once, in naturalibus, that the inquisitive savages might observe the whole extent of the question. Their astonishment and satisfaction were profound and complete. At first they doubted the evidence of their own eyes, spitting upon their fingers and rubbing the skin of the negro to be sure that it was not painted. The wool on the head elicited repeated shouts of applause, and the bandy legs were the subject of unqualified admiration. A jig dance on the part of our ugly friend brought matters to a climax. Wonder was now at its height. Approbation could go no farther. Had Toby but possessed a single spark of ambition he might then have made his fortune for ever by ascending the throne of the Assiniboins, and reigning as King Toby the First.

This incident detained us until late in the day. After interchanging some civilities and presents with the savages, we accepted the aid of six of the band in rowing us about five miles on our route — a very acceptable assistance, and one for which we did not fail to thank Toby. We made, to-day, only twelve miles, and encamped at night on a beautiful island which we long remembered for the delicious fish and fowl which its vicinity afforded us. We staid at this pleasant spot two days, during which we feasted and made merry, with very little care for the morrow, and with very little regard to the numerous beaver which disported around us. We might have taken at this island one or two hundred skins without difficulty. As it was, we collected about twenty. The island is at the mouth of a tolerably large river coming in from the south, and at a point where the Missouri strikes off in a due westerly direction. The latitude is about 48.

May 8. We proceeded with fair winds and fine weather, and after making twenty or twenty-five miles, reached a large river coming in from the north. Where it debouches, however, it is very narrow — not more than a dozen yards wide, and appears to be quite choked up with mud. Upon ascending it a short distance, a fine bold stream is seen, seventy or eighty yards wide, and very deep, passing through a beautiful valley, abounding in game. Our new guide told us the name of this river, but I have no memorandum of it. Robert Greely shot here some geese which build their nests upon trees.

May 9. In many places a little distant from the river banks, to-day, we observed the ground encrusted with a white substance which proved to be a strong salt. We made only fifteen miles, owing to several petty hindrances, and encamped at night on the main land, among some clumps of cotton-wood and rabbit-berry bushes.

May 10. To-day the weather was cold, and the wind strong, but fair. We made great headway. The hills in this vicinity are rough and jagged, showing irregular broken masses of rock, some of which tower to a great height, and appear to have been subject to the action of water. We picked up several pieces of petrified wood and bone; and coal was scattered about in every direction. The river gets very crooked.

May 11. Detained the greater part of the day by squalls and rain. Towards evening it cleared up beautifully with a fair wind, of which we took advantage, making ten miles before encamping. Several fat beavers were caught, and a wolf was shot upon the bank. He seemed to have strayed from a large herd which were prowling about us.

May 12. Landed to-day at noon, after making ten miles, upon a small steep island, for the purpose of overhauling some of our things. As we were about taking our departure, one of the Canadians, who led the van of the party and was several yards in advance, suddenly disappeared from our view with a loud scream. We all ran forward immediately, and laughed heartily upon finding that our man had only tumbled into an empty cache, from which we soon extricated him. Had he been alone, however, there is much room for question if he would have got out at all. We examined the hole carefully but found nothing in it beyond a few empty bottles; we did not even see any thing serving to show whether French, British, or Americans had concealed their goods here; and we felt some curiosity upon this point.

May 13. Arrived at the junction of the Yellowstone with the Missouri, after making twenty-five miles during the day. Misquash here left us, and returned home.
