One of us asked an individual if they were Kiawas, and was answered in the affirmative; he asked a second, if they were Kaskaias, and a third, if they were Arrapahoes, who both also answered affirmatively. This conduct, added to their general deportment, served to excite our suspicions and redouble our vigilance. Two or three other little detached squads were now seen to approach, also singing the scalp {61} song. Our interpreters having joined us, it was proposed that we should avail ourselves of the shade of a large tree which stood near the river, to sit down and smoke with them. They reared their spears against the tree with apparent carelessness and indifference, and took their seats in the form of a semicircle on the ground. Having staked our horses in the rear, and stationed the men to protect them and the baggage, we seated ourselves, and circulated the pipe as usual. But as the party opposed to us was nearly quadruple our number, we did not choose to follow their example in relinquishing our arms, but grasped them securely in our hands, and retained a cautious attitude. Bijeau ascertained that they were a Shienne war-party, on their return from an expedition against the Pawnee Loups. They had killed one squaw, whose scalp was suspended to the spear of the partizan or leader of the party, the handle of which was decorated with strips of red and white cloth, beads, and tail plumes of the war-eagle. He also informed us, that he recognized several of them, particularly a chief who sat next to him, whose person himself and party had formerly seized upon, and detained as a hostage for the recovery of some horses that had been stolen. The chief, however, did not now betray any symptoms of a disposition to retaliate for that act, though, without doubt, he regarded us as in his power. Our interpreter readily conversed with them through the medium of a Crow prisoner, whose language he partially understood. The partizan who killed the victim of this excursion, and two others, one of whom first struck the dead body, and the other who took off the scalp, were painted deep black with charcoal, and almost the entire body being exposed, rendered the effect more impressive. One of the latter, a tall athletic figure, remained standing behind us, and refused to smoke when the pipe was offered to him, alleging {62} as an excuse, the obligation of a vow he had made against the use of tobacco, on the demise of his late father.
