FROM THE MIDDLE to the end of May, Captain Bonneville pursued a western course over vast undulating plains, destitute of tree or shrub, rendered miry by occasional rain, and cut up by deep water-courses where they had to dig roads for their wagons down the soft crumbling banks and to throw bridges across the streams. The weather had attained the summer heat; the thermometer standing about fifty-seven degrees in the morning, early, but rising to about ninety degrees at noon. The incessant breezes, however, which sweep these vast plains render the heats endurable. Game was scanty, and they had to eke out their scanty fare with wild roots and vegetables, such as the Indian potato, the wild onion, and the prairie tomato, and they met with quantities of "red root," from which the hunters make a very palatable beverage. The only human being that crossed their path was a Kansas warrior, returning from some solitary expedition of bravado or revenge, bearing a Pawnee scalp as a trophy.
The country gradually rose as they proceeded westward, and their route took them over high ridges, commanding wide and beautiful prospects. The vast plain was studded on the west with innumerable hills of conical shape, such as are seen north of the Arkansas River. These hills have their summits apparently cut off about the same elevation, so as to leave flat surfaces at top. It is conjectured by some that the whole country may originally have been of the altitude of these tabular hills; but through some process of nature may have sunk to its present level; these insulated eminences being protected by broad foundations of solid rock.
Captain Bonneville mentions another geological phenomenon north of Red River, where the surface of the earth, in considerable tracts of country, is covered with broad slabs of sandstone, having the form and position of grave-stones, and looking as if they had been forced up by some subterranean agitation. "The resemblance," says he, "which these very remarkable spots have in many places to old church-yards is curious in the extreme. One might almost fancy himself among the tombs of the pre-Adamites."
On the 2d of June, they arrived on the main stream of the Nebraska or Platte River; twenty-five miles below the head of the Great Island. The low banks of this river give it an appearance of great width. Captain Bonneville measured it in one place, and found it twenty-two hundred yards from bank to bank. Its depth was from three to six feet, the bottom full of quicksands. The Nebraska is studded with islands covered with that species of poplar called the cotton-wood tree. Keeping up along the course of this river for several days, they were obliged, from the scarcity of game, to put themselves upon short allowance, and, occasionally, to kill a steer. They bore their daily labors and privations, however, with great good humor, taking their tone, in all probability, from the buoyant spirit of their leader. "If the weather was inclement," said the captain, "we watched the clouds, and hoped for a sight of the blue sky and the merry sun. If food was scanty, we regaled ourselves with the hope of soon falling in with herds of buffalo, and having nothing to do but slay and eat." We doubt whether the genial captain is not describing the cheeriness of his own breast, which gave a cheery aspect to everything around him.
There certainly were evidences, however, that the country was not always equally destitute of game. At one place, they observed a field decorated with buffalo skulls, arranged in circles, curves, and other mathematical figures, as if for some mystic rite or ceremony. They were almost innumerable, and seemed to have been a vast hecatomb offered up in thanksgiving to the Great Spirit for some signal success in the chase.
On the 11th of June, they came to the fork of the Nebraska, where it divides itself into two equal and beautiful streams. One of these branches rises in the west-southwest, near the headwaters of the Arkansas. Up the course of this branch, as Captain Bonneville was well aware, lay the route to the Camanche and Kioway Indians, and to the northern Mexican settlements; of the other branch he knew nothing. Its sources might lie among wild and inaccessible cliffs, and tumble and foam down rugged defiles and over craggy precipices; but its direction was in the true course, and up this stream he determined to prosecute his route to the Rocky Mountains. Finding it impossible, from quicksands and other dangerous impediments, to cross the river in this neighborhood, he kept up along the south fork for two days, merely seeking a safe fording place. At length he encamped, caused the bodies of the wagons to be dislodged from the wheels, covered with buffalo hide, and besmeared with a compound of tallow and ashes; thus forming rude boats. In these, they ferried their effects across the stream, which was six hundred yards wide, with a swift and strong current. Three men were in each boat, to manage it; others waded across pushing the barks before them. Thus all crossed in safety. A march of nine miles took them over high rolling prairies to the north fork; their eyes being regaled with the welcome sight of herds of buffalo at a distance, some careering the plain, others grazing and reposing in the natural meadows.
Skirting along the north fork for a day or two, excessively annoyed by musquitoes and buffalo gnats, they reached, in the evening of the 17th, a small but beautiful grove, from which issued the confused notes of singing birds, the first they had heard since crossing the boundary of Missouri. After so many days of weary travelling through a naked, monotonous and silent country, it was delightful once more to hear the song of the bird, and to behold the verdure of the grove. It was a beautiful sunset, and a sight of the glowing rays, mantling the tree-tops and rustling branches, gladdened every heart. They pitched their camp in the grove, kindled their fires, partook merrily of their rude fare, and resigned themselves to the sweetest sleep they had enjoyed since their outset upon the prairies.
The country now became rugged and broken. High bluffs advanced upon the river, and forced the travellers occasionally to leave its banks and wind their course into the interior. In one of the wild and solitary passes they were startled by the trail of four or five pedestrians, whom they supposed to be spies from some predatory camp of either Arickara or Crow Indians. This obliged them to redouble their vigilance at night, and to keep especial watch upon their horses. In these rugged and elevated regions they began to see the black-tailed deer, a species larger than the ordinary kind, and chiefly found in rocky and mountainous countries. They had reached also a great buffalo range; Captain Bonneville ascended a high bluff, commanding an extensive view of the surrounding plains. As far as his eye could reach, the country seemed absolutely blackened by innumerable herds. No language, he says, could convey an adequate idea of the vast living mass thus presented to his eye. He remarked that the bulls and cows generally congregated in separate herds.
Opposite to the camp at this place was a singular phenomenon, which is among the curiosities of the country. It is called the chimney. The lower part is a conical mound, rising out of the naked plain; from the summit shoots up a shaft or column, about one hundred and twenty feet in height, from which it derives its name. The height of the whole, according to Captain Bonneville, is a hundred and seventy-five yards. It is composed of indurated clay, with alternate layers of red and white sandstone, and may be seen at the distance of upward of thirty miles.
On the 21st, they encamped amidst high and beetling cliffs of indurated clay and sandstone, bearing the semblance of towers, castles, churches, and fortified cities. At a distance, it was scarcely possible to persuade one's self that the works of art were not mingled with these fantastic freaks of nature. They have received the name of Scott's Bluffs, from a melancholy circumstance. A number of years since, a party were descending the upper part of the river in canoes, when their frail barks were overturned and all their powder spoiled. Their rifles being thus rendered useless, they were unable to procure food by hunting and had to depend upon roots and wild fruits for subsistence. After suffering extremely from hunger, they arrived at Laramie's Fork, a small tributary of the north branch of the Nebraska, about sixty miles above the cliffs just mentioned. Here one of the party, by the name of Scott, was taken ill; and his companions came to a halt, until he should recover health and strength sufficient to proceed. While they were searching round in quest of edible roots, they discovered a fresh trail of white men, who had evidently but recently preceded them. What was to be done? By a forced march they might overtake this party, and thus be able to reach the settlements in safety. Should they linger, they might all perish of famine and exhaustion. Scott, however, was incapable of moving; they were too feeble to aid him forward, and dreaded that such a clog would prevent their coming up with the advance party. They determined, therefore, to abandon him to his fate. Accordingly, under presence of seeking food, and such simples as might be efficacious in his malady, they deserted him and hastened forward upon the trail. They succeeded in overtaking the party of which they were in quest, but concealed their faithless desertion of Scott; alleging t in company with others, came suddenly upon the bleached bones and grinning skull of a human skeleton, which, by certain signs they recognized for the remains of Scott. This was sixty long miles from the place where they had abandoned him; and it appeared that the wretched man had crawled that immense distance before death put an end to his miseries. The wild and picturesque bluffs in the neighborhood of his lonely grave have ever since borne his name.
Amidst this wild and striking scenery, Captain Bonneville, for the first time, beheld flocks of the ahsahta or bighorn, an animal which frequents these cliffs in great numbers. They accord with the nature of such scenery, and add much to its romantic effect; bounding like goats from crag to crag, often trooping along the lofty shelves of the mountains, under the guidance of some venerable patriarch with horns twisted lower than his muzzle, and sometimes peering over the edge of a precipice, so high that they appear scarce bigger than crows; indeed, it seems a pleasure to them to seek the most rugged and frightful situations, doubtless from a feeling of security.
This animal is commonly called the mountain sheep, and is often confounded with another animal, the "woolly sheep," found more to the northward, about the country of the Flatheads. The latter likewise inhabits cliffs in summer, but descends into the valleys in the winter. It has white wool, like a sheep, mingled with a thin growth of long hair; but it has short legs, a deep belly, and a beard like a goat. Its horns are about five inches long, slightly curved backwards, black as jet, and beautifully polished. Its hoofs are of the same color. This animal is by no means so active as the bighorn; it does not bound much, but sits a good deal upon its haunches. It is not so plentiful either; rarely more than two or three are seen at a time. Its wool alone gives a resemblance to the sheep; it is more properly of the flesh is said toavor; some have ce might be valuaid to be as fin goat of Cashmer to be procured in sufficient quantities.
The ahsahta, argali, or bighorn, on the contrary, has short hair like a deer, and resembles it in shape, but has the head and horns of a sheep, and its flesh is said to be delicious mutton. The Indians consider it more sweet and delicate than any other kind of venison. It abounds in the Rocky Mountains, from the fiftieth degree of north latitude, quite down to California; generally in the highest regions capable of vegetation; sometimes it ventures into the valleys, but on the least alarm, regains its favorite cliffs and precipices, where it is perilous, if not impossible for the hunter to follow.
