As it goes on, the descent within the next two hundred and forty poles is only four feet; from this, passing a run or deep ravine, the descent in four hundred poles is thirteen feet; within two hundred and forty poles, another descent of eighteen feet; thence, in one hundred and sixty poles, a descent of six feet; after which, to the mouth of Portage Creek, a distance of two hundred and eighty poles, the descent is ten feet. From this survey and estimate, it results that the river experiences a descent of three hundred and fifty-two feet in the distance of two and three quarter miles, from the commencement of the rapids to the mouth of Portage Creek, exclusive of the almost impassable rapids which extend for a mile below its entrance."

On the twenty-first of the month, all the needed preparations having been finished, the arduous work of making the portage, or carry, was begun. All the members of the expedition were now together, and the two captains divided with their men the labor of hunting, carrying luggage, boat-building, exploring, and so on. They made three camps, the lower one on Portage Creek, the next at Willow Run [see map], and a third at a point opposite White Bear Islands. The portage was not completed until July second. They were often delayed by the breaking down of their rude carriages, and during the last stage of their journey much of their luggage was carried on the backs of the men. They were also very much annoyed with the spines of the prickly pear, a species of cactus, which, growing low on the ground, is certain to be trampled upon by the wayfarer. The spines ran through the moccasins of the men and sorely wounded their feet. Thus, under date of June twenty-fourth, the journal says (It should be understood that the portage was worked from above and below the rapids):--

"On going down yesterday Captain Clark cut off several angles of the former route, so as to shorten the portage considerably, and marked it with stakes. He arrived there in time to have two of the canoes carried up in the high plain, about a mile in advance. Here they all repaired their moccasins, and put on double soles to protect them from the prickly pear, and from the sharp points of earth which have been formed by the trampling of the buffalo during the late rains. This of itself is sufficient to render the portage disagreeable to one who has no burden; but as the men are loaded as heavily as their strength will permit, the crossing is really painful. Some are limping with the soreness of their feet; others are scarcely able to stand for more than a few minutes, from the heat and fatigue. They are all obliged to halt and rest frequently; at almost every stopping-place they fall, and many of them are asleep in an instant; yet no one complains, and they go on with great cheerfulness. At the camp, midway in the portage, Drewyer and Fields joined them; for, while Captain Lewis was looking for them at Medicine River, they returned to report the absence of Shannon, about whom they had been very uneasy. They had killed several buffalo at the bend of the Missouri above the falls, dried about eight hundred pounds of meat, and got one hundred pounds of tallow; they had also killed some deer, but had seen no elk."

Under this date, too, Captain Lewis, who was with another branch of the expedition, makes this note: "Such as were able to shake a foot amused themselves in dancing on the green to the music of the violin which Cruzatte plays extremely well."

The journal continues:--

"We were now occupied [at White Bear camp] in fitting up a boat of skins, the frame of which had been prepared for the purpose at Harper's Ferry in Virginia. It was made of iron, thirty-six feet long, four and one-half feet in the beam, and twenty-six inches wide in the bottom. Two men had been sent this morning for timber to complete it, but they could find scarcely any even tolerably straight sticks four and one-half feet long; and as the cottonwood is too soft and brittle, we were obliged to use willow and box-elder."

On the twenty-seventh, the main party, which was working on the upper part of the portage, joined that of Captain Clark at the lower camp, where a second cache, or place of deposit, had been formed, and where the boat-swivel was now hidden under the rocks. The journal says:--

"The party were employed in preparing timber for the boat, except two who were sent to hunt. About one in the afternoon a cloud arose from the southwest, and brought with it violent thunder, lightning, and hail. Soon after it passed, the hunters came in, from about four miles above us. They had killed nine elk and three bears. As they were hunting on the river they saw a low ground covered with thick brushwood, where from the tracks along shore they thought a bear had probably taken refuge. They therefore landed, without making a noise, and climbed a tree about twenty feet above the ground. Having fixed themselves securely, they raised a loud shout, and a bear instantly rushed toward them. These animals never climb, and therefore when he came to the tree and stopped to look at them, Drewyer shot him in the head. He proved to be the largest we had yet seen; his nose appeared to be like that of a common ox; his fore feet measured nine inches across; the hind feet were seven inches wide and eleven and three quarters long, exclusive of the talons. One of these animals came within thirty yards of the camp last night, and carried off some buffalo-meat which we had placed on a pole."

The party were very much annoyed here by the grizzlies which infested their camp at night. Their faithful dog always gave warning of the approach of one of these monsters; but the men were obliged to sleep with their guns by their side, ready to repel the enemy at a moment's notice.

Captain Clark finally broke up the camp on Portage Creek, June 28, having deposited in his cache whatever could be left behind without inconvenience. "On the following day," the journal says:--

"Finding it impossible to reach the upper end of the portage with the present load, in consequence of the state of the road after the rain, he sent back nearly all his party to bring on the articles which had been left yesterday. Having lost some notes and remarks which he had made on first ascending the river, he determined to go up to the Whitebear Islands along its banks, in order to supply the deficiency. He there left one man to guard the baggage, and went on to the falls, accompanied by his servant York, Chaboneau, and his wife with her young child.

"On his arrival there he observed a very dark cloud rising in the west, which threatened rain, and looked around for some shelter; but could find no place where the party would be secure from being blown into the river, if the wind should prove as violent as it sometimes does in the plains. At length, about a quarter of a mile above the falls, he found a deep ravine, where there were some shelving rocks, under which he took refuge. They were on the upper side of the ravine near the river, perfectly safe from the rain, and therefore laid down their guns, compass, and other articles which they carried with them. The shower was at first moderate; it then increased to a heavy rain, the effects of which they did not feel; but soon after, a torrent of rain and hail descended. The rain seemed to fall in a solid mass, and instantly, collecting in the ravine, came rolling down in a dreadful current, carrying the mud, rocks, and everything that opposed it. Captain Clark fortunately saw it a moment before it reached them, and springing up with his gun and shot-pouch in his left hand, with his right clambered up the steep bluff, pushing on the Indian woman with her child in her arms; her husband too had seized her hand and was pulling her tip the hill, but he was so terrified at the danger that he remained frequently motionless; and but for Captain Clark, himself and his wife and child would have been lost. So instantaneous was the rise of the water that, before Captain Clark had reached his gun and begun to ascend the bank, the water was up to his waist, and he could scarcely get up faster than it rose, till it reached the height of fifteen feet, with a furious current which, had they waited a moment longer, would have swept them into the river just above the Great Falls, down which they must inevitably have been precipitated. They reached the plain in safety and found York, who had separated from them just before the storm to hunt some buffalo, and was now returning to find his master. They had been obliged to escape so rapidly that Captain Clark lost his compass [that is, circumferentor] and umbrella, Chaboneau left his gun, with Captain Lewis' wiping-rod, shot-pouch, and tomahawk, and the Indian woman had just time to grasp her child, before the net in which it lay at her feet was carried down the current."

Such a storm is known in the West as a cloud-burst. Overland emigrants in the early rush to California often suffered loss from these sudden deluges. A party of men, with wagons and animals, have been known to be swept away and lost in a flood bursting in a narrow canyon in the mountains.

"Captain Clark now relinquished his intention of going up the river, and returned to the camp at Willow Run. Here he found that the party sent this morning for the baggage had all returned to camp in great confusion, leaving their loads in the plain. On account of the heat, they generally go nearly naked, and with no covering on their heads. The hail was so large, and driven so furiously against them by the high wind, that it knocked several of them down: one of them, particularly, was thrown on the ground three times, and most of them were bleeding freely, and complained of being much bruised. Willow Run had risen six feet since the rain; and, as the plains were so wet that they could not proceed, they passed the night at their camp.

"At the White Bear camp, also," (says Lewis), "we had not been insensible to the hailstorm, though less exposed. In the morning there had been a heavy shower of rain, after which it became fair. After assigning to the men their respective employments, Captain Lewis took one of them, and went to see the large fountain near the falls. . . . It is, perhaps, the largest in America, and is situated in a pleasant level plain, about twenty-five yards from the river, into which it falls over some steep, irregular rocks, with a sudden ascent of about six feet in one part of its course. The water boils up from among the rocks, and with such force near the centre that the surface seems higher there than the earth on the sides of the fountain, which is a handsome turf of fine green grass. The water is extremely pure, cold, and pleasant to the taste, not being impregnated with lime or any foreign substance. It is perfectly transparent, and continues its bluish cast for half a mile down the Missouri, notwithstanding the rapidity of the river. After examining it for some time, Captain Lewis returned to the camp.

. . . "Two men were sent [June 30] to the falls to look for the articles lost yesterday; but they found nothing but the compass, covered with mud and sand, at the mouth of the ravine. The place at which Captain Clark had been caught by the storm was filled with large rocks. The men complain much of the bruises received yesterday from the hail. A more than usual number of buffalo appeared about the camp to-day, and furnished plenty of meat. Captain Clark thought that at one view he must have seen at least ten thousand."

Of the party at the upper camp, opposite White Bear Islands, the journal makes this observation:--

"The party continues to be occupied with the boat, the cross-bars for which are now finished, and there remain only the strips to complete the woodwork. The skins necessary to cover it have already been prepared; they amount to twenty-eight elk-skins and four buffalo-skins. Among our game were two beaver, which we have had occasion to observe are found wherever there is timber. We also killed a large bull-bat or goatsucker, of which there are many in this neighborhood, resembling in every respect those of the same species in the United States. We have not seen the leather-winged bat for some time, nor are there any of the small goatsucker in this part of the Missouri. We have not seen that species of goatsucker called the whippoorwill, which is commonly confounded in the United States with the large goatsucker which we observe here. This last prepares no nest, but lays its eggs on the open plains; they generally begin to sit on two eggs, and we believe raise only one brood in a season; at the present moment they are just hatching their young."

Dr. Coues says that we should bear in mind that this was written "when bats were birds and whales were fishes for most persons." The journal confounds bats, which are winged mammals, with goatsuckers, or whippoorwills, which are birds.

The second of July was an interesting date for the explorers. On that day we find the following entry in their journal:--

"A shower of rain fell very early this morning. We then despatched some men for the baggage left behind yesterday, and the rest were engaged in putting the boat together. This was accomplished in about three hours, and then we began to sew on the leather over the crossbars of iron on the inner side of the boat which form the ends of the sections. By two o'clock the last of the baggage arrived, to the great delight of the party, who were anxious to proceed. The mosquitoes we find very troublesome.

"Having completed our celestial observations, we went over to the large island to make an attack upon its inhabitants, the bears, which have annoyed us very much of late, and were prowling about our camp all last night. We found that the part of the island frequented by the bears forms an almost impenetrable thicket of the broad-leaved willow. Into this we forced our way in parties of three; but could see only one bear, which instantly attacked Drewyer. Fortunately, as he was rushing on, the hunter shot him through the heart within twenty paces and he fell, which enabled Drewyer to get out of his way. We then followed him one hundred yards, and found that the wound had been mortal.

"Not being able to discover any more of these animals, we returned to camp. Here, in turning over some of the baggage, we caught a rat somewhat larger than the common European rat, and of a lighter color; the body and outer parts of the legs and head of a light lead color; the inner side of the legs, as well as the belly, feet, and ears, white; the ears are not covered with hair, and are much larger than those of the common rat; the toes also are longer; the eyes are black and prominent, the whiskers very long and full; the tail is rather longer than the body, and covered with fine fur and hair of the same size with that on the back, which is very close, short, and silky in its texture. This was the first we had met, although its nests are very frequent in the cliffs of rocks and hollow trees, where we also found large quantities of the shells and seed of the prickly-pear."

The queer rat discovered by Lewis and Clark was then unknown to science. It is now known in the Far West as the pack-rat. It lives in holes and crevices of the rocks, and it subsists on the shells and seeds of the prickly pear, which is usually abundant in the hunting grounds of the little animal. The explorers were now constantly in full view of the Rocky Mountain, on which, however, their present title had not then been conferred. Under date of July 2, the journal says:--

"The mosquitoes are uncommonly troublesome. The wind was again high from the southwest. These winds are in fact always the coldest and most violent which we experience, and the hypothesis which we have formed on that subject is, that the air, coming in contact with the Snowy Mountains, immediately becomes chilled and condensed, and being thus rendered heavier than the air below, it descends into the rarefied air below, or into the vacuum formed by the constant action of the sun on the open unsheltered plains. The clouds rise suddenly near these mountains, and distribute their contents partially over the neighboring plains. The same cloud will discharge hail alone in one part, hail and rain in another, and rain only in a third, all within the space of a few miles; while at the same time there is snow falling on the mountains to the southeast of us. There is at present no snow on those mountains; that which covered them on our arrival, as well as that which has since fallen, having disappeared. The mountains to the north and northwest of us are still entirely covered with snow; indeed, there has been no perceptible diminution of it since we first saw them, which induces a belief either that the clouds prevailing at this season do not reach their summits or that they deposit their snow only. They glisten with great beauty when the sun shines on them in a particular direction, and most probably from this glittering appearance have derived the name of the Shining Mountains."

A mysterious noise, heard by the party, here engaged their attention, as it did years afterwards the attention of other explorers. The journal says:--

"Since our arrival at the falls we have repeatedly heard a strange noise coming from the mountains in a direction a little to the north of west. It is heard at different periods of the day and night (sometimes when the air is perfectly still and without a cloud), and consists of one stroke only, or of five or six discharges in quick succession. It is loud, and resembles precisely the sound of a six-pound piece of ordnance at the distance of three miles. The Minnetarees frequently mentioned this noise, like thunder, which they said the mountains made; but we had paid no attention to it, believing it to have been some superstition, or perhaps a falsehood. The watermen also of the party say that the Pawnees and Ricaras give the same account of a noise heard in the Black Mountains to the westward of them. The solution of the mystery given by the philosophy of the watermen is, that it is occasioned by the bursting of the rich mines of silver confined within the bosom of the mountains."

Of these strange noises there are many explanations, the most plausible being that they are caused by the explosion of the species of stone known as the geode, fragments of which are frequently found among the mountains. The geode has a hollow cell within, lined with beautiful crystals of many colors.

Independence Day, 1805, was celebrated with becoming patriotism and cheerfulness by these far-wandering adventurers. Their record says:--

"An elk and a beaver are all that were killed to-day; the buffalo seem to have withdrawn from our neighborhood, though several of the men, who went to-day to visit the falls for the first time, mention that they are still abundant at that place. We contrived, however, to spread not a very sumptuous but a comfortable table in honor of the day, and in the evening gave the men a drink of spirits, which was the last of our stock. Some of them appeared sensible to the effects of even so small a quantity; and as is usual among them on all festivals, the fiddle was produced and a dance begun, which lasted till nine o'clock, when it was interrupted by a heavy shower of rain. They continued their merriment, however, till a late hour."

Their bill-of-fare, according to Captain Lewis, was bacon, beans, suet dumplings, and buffalo meat, which, he says, "gave them no just cause to covet the sumptuous feasts of our countrymen on this day." More than a year passed before they again saw and tasted spirits.

Great expectations were entertained of the boat that was built here on the iron frame brought all the way from Harper's Ferry, Virginia. The frame was covered with dressed skins of buffalo and elk, the seams being coated with a composition of powdered charcoal and beeswax, in default of tar or pitch. This craft was well named the "Experiment," and a disappointing experiment it proved to be. Here is Captain Lewis' account of her failure:

"The boat having now become sufficiently dry, we gave her a coat of the composition, which after a proper interval was repeated, and the next morning, Tuesday, July 9th, she was launched into the water, and swam perfectly well. The seats were then fixed and the oars fitted; but after we had loaded her, as well as the canoes, and were on the point of setting out, a violent wind caused the waves to wet the baggage, so that we were forced to unload the boats. The wind continued high until evening, when to our great disappointment we discovered that nearly all the composition had separated from the skins and left the seams perfectly exposed; so that the boat now leaked very much. To repair this misfortune without pitch is impossible, and as none of that article is to be procured, we therefore, however reluctantly, are obliged to abandon her, after having had so much labor in the construction. We now saw that the section of the boat covered with buffalo-skins on which hair had been left answered better than the elk-skins, and leaked but little; while that part which was covered with hair about one-eighth of an inch retained the composition perfectly, and remained sound and dry. From this we perceived that had we employed buffalo instead of elk skins, not singed them so closely as we did, and carefully avoided cutting the leather in sewing, the boat would have been sufficient even with the present composition; or had we singed instead of shaving the elk-skins, we might have succeeded. But we discovered our error too late; the buffalo had deserted us, and the travelling season was so fast advancing that we had no time to spare for experiments; therefore, finding that she could be no longer useful, she was sunk in the water, so as to soften the skins, and enable us the more easily to take her to pieces.

"It now became necessary to provide other means for transporting the baggage which we had intended to stow in her. For this purpose we shall want two more canoes; but for many miles-- from below the mouth of the Musselshell River to this place-- we have not seen a single tree fit to be used in that way. The hunters, however, who have hitherto been sent after timber, mention that there is a low ground on the opposite side of the river, about eight miles above us by land, and more than twice that distance by water, in which we may probably find trees large enough for our purposes. Captain Clark determined, therefore, to set out by land for that place with ten of the best workmen, who would be occupied in building the canoes till the rest of the party, after taking the boat to pieces, and making the necessary deposits, should transport the baggage, and join them with the other six canoes.

"He accordingly passed over to the opposite side of the river with his party next day, and proceeded on eight miles by land, the distance by water being twenty-three and three quarter miles. Here he found two cottonwood trees; but, on cutting them down, one proved to be hollow, split at the top in falling, and both were much damaged at the bottom. He searched the neighborhood, but could find none which would suit better, and therefore was obliged to make use of those which he had felled, shortening them in order to avoid the cracks, and supplying the deficiency by making them as wide as possible. They were equally at a loss for wood of which they might make handles for their axes, the eyes of which not being round, they were obliged to split the timber in such a manner that thirteen of the handles broke in the course of the day, though made of the best wood they could find for the purpose, which was the chokecherry.

"The rest of the party took the frame of the boat to pieces, deposited it in a cache or hole, with a draught of the country from Fort Mandan to this place, and also some other papers and small articles of less importance."

High winds prevented the party from making rapid progress, and notwithstanding the winds they were greatly troubled with mosquitoes. Lest the reader should think the explorers too sensitive on the subject of these troublesome pests, it should be said that only western travellers can realize the numbers and venom of the mosquitoes of that region. Early emigrants across the continent were so afflicted by these insects that the air at times seemed full of gray clouds of them. It was the custom of the wayfarers to build a "smudge," as it was called, a low, smouldering fire of green boughs and brush, the dense smoke from which (almost as annoying as the mosquitoes) would drive off their persecutors as long, as the victims CONTINUES ON NEXT PAGE, CLICK HERE
