      ON THE 25TH of July, Captain Bonneville struck his tents, and set out on his route for the Bighorn, at the head of a party of fifty-six men, including those who were to embark with Cerre. Crossing the Green River valley, he proceeded along the south point of the Wind River range of mountains, and soon fell upon the track of Mr. Robert Campbell’s party, which had preceded him by a day. This he pursued, until he perceived that it led down the banks of the Sweet Water to the southeast. As this was different from his proposed direction, he left it; and turning to the northeast, soon came upon the waters of the Popo Agie. This stream takes its rise in the Wind River Mountains. Its name, like most Indian names, is characteristic. Popo, in the Crow language, signifies head; and Agie, river. It is the head of a long river, extending from the south end of the Wind River Mountains in a northeast direction, until it falls into the Yellowstone. Its course is generally through plains, but is twice crossed by chains of mountains; the first called the Littlehorn; the second, the Bighorn. After it has forced its way through the first chain, it is called the Horn River; after the second chain, it is called the Bighorn River. Its passage through this last chain is rough and violent; making repeated falls, and rushing down long and furious rapids, which threaten destruction to the navigator; though a hardy trapper is said to have shot down them in a canoe. At the foot of these rapids, is the head of navigation; where it was the intention of the parties to construct boats, and embark.

      Proceeding down along the Popo Agie, Captain Bonneville came again in full view of the “Bluffs,” as they are called, extending from the base of the Wind River Mountains far away to the east, and presenting to the eye a confusion of hills and cliffs of red sandstone, some peaked and angular, some round, some broken into crags and precipices, and piled up in fantastic masses; but all naked and sterile. There appeared to be no soil favorable to vegetation, nothing but coarse gravel; yet, over all this isolated, barren landscape, were diffused such atmospherical tints and hues, as to blend the whole into harmony and beauty.

      In this neighborhood, the captain made search for “the great Tar Spring,” one of the wonders of the mountains; the medicinal properties of which, he had heard extravagantly lauded by the trappers. After a toilsome search, he found it at the foot of a sand-bluff, a little east of the Wind River Mountains; where it exuded in a small stream of the color and consistency of tar. The men immediately hastened to collect a quantity of it, to use as an ointment for the galled backs of their horses, and as a balsam for their own pains and aches. From the description given of it, it is evidently the bituminous oil, called petrolium or naphtha, which forms a principal ingredient in the potent medicine called British Oil. It is found in various parts of Europe and Asia, in several of the West India islands, and in some places of the United States. In the state of New York, it is called Seneca Oil, from being found near the Seneca lake.

      The Crow country has other natural curiosities, which are held in superstitious awe by the Indians, and considered great marvels by the trappers. Such is the Burning Mountain, on Powder River, abounding with anthracite coal. Here the earth is hot and cracked; in many places emitting smoke and sulphurous vapors, as if covering concealed fires. A volcanic tract of similar character is found on Stinking River, one of the tributaries of the Bighorn, which takes its unhappy name from the odor derived from sulphurous springs and streams. This last mentioned place was first discovered by Colter, a hunter belonging to Lewis and Clarke’s exploring party, who came upon it in the course of his lonely wanderings, and gave such an account of its gloomy terrors, its hidden fires, smoking pits, noxious streams, and the all-pervading “smell of brimstone,” that it received, and has ever since retained among trappers, the name of “Colter’s Hell!”

      Resuming his descent along the left bank of the Popo Agie, Captain Bonneville soon reached the plains; where he found several large streams entering from the west. Among these was Wind River, which gives its name to the mountains among which it takes its rise. This is one of the most important streams of the Crow country. The river being much swollen, Captain Bonneville halted at its mouth, and sent out scouts to look for a fording place. While thus encamped, he beheld in the course of the afternoon a long line of horsemen descending the slope of the hills on the opposite side of the Popo Agie. His first idea was that they were Indians; he soon discovered, however, that they were white men, and, by the long line of packhorses, ascertained them to be the convoy of Campbell, which, having descended the Sweet Water, was now on its way to the Horn River.

      The two parties came together two or three days afterwards, on the 4th of August, after having passed through the gap of the Littlehorn Mountain. In company with Campbell’s convoy was a trapping party of the Rocky Mountain Company, headed by Fitzpatrick; who, after Campbell’s embarkation on the Bighorn, was to take charge of all the horses, and proceed on a trapping campaign. There were, moreover, two chance companions in the rival camp. One was Captain Stewart, of the British army, a gentleman of noble connections, who was amusing himself by a wandering tour in the Far West; in the course of which, he had lived in hunter’s style; accompanying various bands of traders, trappers, and Indians; and manifesting that relish for the wilderness that belongs to men of game spirit.

      The other casual inmate of Mr. Campbell’s camp was Mr. Nathaniel Wyeth; the self-same leader of the band of New England salmon fishers, with whom we parted company in the valley of Pierre’s Hole, after the battle with the Blackfeet. A few days after that affair, he again set out from the rendezvous in company with Milton Sublette and his brigade of trappers. On his march, he visited the battle ground, and penetrated to the deserted fort of the Blackfeet in the midst of the wood. It was a dismal scene. The fort was strewed with the mouldering bodies of the slain; while vultures soared aloft, or sat brooding on the trees around; and Indian dogs howled about the place, as if bewailing the death of their masters. Wyeth travelled for a considerable distance to the southwest, in company with Milton Sublette, when they separated; and the former, with eleven men, the
