sign of friendship among the Indians on the Missouri and the Rocky mountains.  As usual, captain Lewis repeated this signal three times:  still the Indian kept his position, and looked with an air of suspicion on Drewyer and Shields who were now advancing on each side.  Captain Lewis was afraid to make any signal for them to halt, lest he should increase the suspicions of the Indian, who began to be uneasy, and they too distant to hear his voice.  He, therefore, took from his pack some beads, a looking-glass and a few trinkets, which he had brought for the purpose, and leaving his gun advanced unarmed towards the Indian.  He remained in the same position till captain Lewis came within two hundred yards of him, when he turned his horse, and began to move off slowly; captain Lewis then called out to him, in as loud a voice as he could, repeating the word, tabba bone! which in the Shoshonee language means white man; but looking over his shoulder the Indian kept his eyes on Drewyer and Shields, who were still advancing, without recollecting the impropriety of doing so at such a moment, till captain Lewis made a signal to them to halt; this Drewyer obeyed, but Shields did not observe it, and still went forward:  seeing Drewyer halt the Indian turned his horse about as if to wait for captain Lewis who now reached within one hundred and fifty paces, repeating the word tabba bone, and holding up the trinkets in his hand, at the same time stripping up the sleeve of his shirt to show the colour of his skin.  The Indian suffered him to advance within one hundred paces, then suddenly turned his horse, and giving him the whip, leaped across the creek, and disappeared in an instant among the willow bushes:  with him vanished all the hopes which the sight of him had inspired of a friendly introduction to his countrymen.  Though sadly disappointed by the imprudence of his two men, captain Lewis determined to make the incident of some use, and therefore calling the men to him they all set off after the track of the horse, which they hoped might lead them to the camp of the Indian who had fled, or if he had given the alarm to any small party, their track might conduct them to the body of the nation.  They now fixed a small flag of the United States on a pole, which was carried by one of the men as a signal of their friendly intentions, should the Indians observe them as they were advancing.  The route lay across an island formed by a nearly equal division of the creek in the bottom:  after reaching the open grounds on the right side of the creek, the track turned towards some high hills about three miles distant.  Presuming that the Indian camp might be among these hills, and that by advancing hastily he might be seen and alarm them, captain Lewis sought an elevated situation near the creek, had a fire made of willow brush, and took breakfast.  At the same time he prepared a small assortment of beads, trinkets, awls, some paint and a looking glass, and placed them on a pole near the
