If Crooks and M'Lellan had been exasperated by the insolent conduct of the Sioux Tetons, and the loss which it had occasioned, those freebooters had been no less indignant at being outwitted by the white men, and disappointed of their anticipated gains, and it was apprehended they would be particularly hostile against the present expedition, when they should learn that these gentlemen were engaged in it.
All these causes of uneasiness were concealed as much as possible from the Canadian voyageurs, lest they should become intimidated;it was impossible, however, to prevent the rumors brought by the Indians from leaking out, and they became subjects of gossiping and exaggeration. The chief of the Omahas, too, on returning from a hunting excursion, reported that two men had been killed some distance above, by a band of Sioux. This added to the fears that already began to be excited. The voyageurs pictured to themselves bands of fierce warriors stationed along each bank of the river, by whom they would be exposed to be shot down in their boats: or lurking hordes, who would set on them at night, and massacre them in their encampments. Some lost heart, and proposed to return, rather than fight their way, and, in a manner, run the gauntlet through the country of these piratical marauders. In fact, three men deserted while at this village. Luckily, their place was supplied by three others who happened to be there, and who were prevailed on to join the expedition by promises of liberal pay, and by being fitted out and equipped in complete style.
The irresolution and discontent visible among some of his people, arising at times almost to mutiny, and the occasional desertions which took place while thus among friendly tribes, and within reach of the frontiers, added greatly to the anxieties of Mr.
Hunt, and rendered him eager to press forward and leave a hostile tract behind him, so that it would be as perilous to return as to keep on, and no one would dare to desert.
Accordingly, on the 15th of May he departed from the village of the Omahas, and set forward towards the country of the formidable Sioux Tetons. For the first five days they had a fair and fresh breeze, and the boats made good progress. The wind then came ahead, and the river beginning to rise, and to increase in rapidity, betokened the commencement of the annual flood, caused by the melting of the snow on the Rocky Mountains, and the vernal rains of the upper prairies.
As they were now entering a region where foes might be lying in wait on either bank, it was determined, in hunting for game, to confine themselves principally to the islands, which sometimes extend to considerable length, and are beautifully wooded, affording abundant pasturage and shade. On one of these they killed three buffaloes and two elks, and halting on the edge of a beautiful prairie, made a sumptuous hunter's repast. They had not long resumed their boats and pulled along the river banks when they descried a canoe approaching, navigated by two men, whom, to their surprise, they ascertained to be white men. They proved to be two of those strange and fearless wanderers of the wilderness, the trappers. Their names were Benjamin Jones and Alexander Carson. They had been for two years past hunting and trapping near the head of the Missouri, and were thus floating for thousands of miles in a cockle-shell, down a turbulent stream, through regions infested by savage tribes, yet apparently as easy and unconcerned as if navigating securely in the midst of civilization.
The acquisition of two such hardy, experienced, and dauntless hunters was peculiarly desirable at the present moment. They needed but little persuasion. The wilderness is the home of the trapper; like the sailor, he cares but little to which point of the compass he steers; and Jones and Carson readily abandoned their voyage to St. Louis, and turned their faces towards the Rocky Mountains and the Pacific.
The two naturalists, Mr. Bradbury and Mr. Nuttall, who had joined the expedition at St. Louis, still accompanied it, and pursued their researches on all occasions. Mr. Nuttall seems to have been exclusively devoted to his scientific pursuits. He was a zealous botanist, and all his enthusiasm was awakened at beholding a new world, as it were, opening upon him in the boundless prairies, clad in the vernal and variegated robe of unknown flowers. Whenever the boats landed at meal times, or for any temporary purpose, he would spring on shore, and set out on a hunt for new specimens. Every plant or flower of a rare or unknown species was eagerly seized as a prize. Delighted with the treasures spreading themselves out before him, he went groping and stumbling along among the wilderness of sweets, forgetful of everything but his immediate pursuit, and had often to be sought after when the boats were about to resume their course. At such times he would be found far off in the prairies, or up the course of some petty stream, laden with plants of all kinds.
The Canadian voyageurs, who are a class of people that know nothing out of their immediate line, and with constitutional levity make a jest of anything they cannot understand, were extremely puzzled by this passion for collecting what they considered mere useless weeds. When they saw the worthy botanist coming back heavy laden with his specimens, and treasuring them up as carefully as a miser would his hoard, they used to make merry among themselves at his expense, regarding him as some whimsical kind of madman.
