I had the satisfaction then of saying to the audience, that this was very gratifying to me, inasmuch as many persons had questioned the correctness of the picture of the horse; and some had said in my Exhibition Room, “that it was an imposition—that no Indian on the frontier rode so good a horse.” This was explained to Kee-o-kuk by the interpreter, when he arose again quite indignant at the thought that any one should doubt its correctness, and assured the audience, “that his men, a number of whom never had heard that the picture was painted, knew the horse the moment it was presented; and further, he wished to know why Kee-o-kuk could not ride as good a horse as any white man?” He here received a round of applause, and the interpreter, Mr. Le Clair, rose and stated to the audience, that he recognized the horse the moment it was shewn, and that it was a faithful portrait of the horse that he sold to Kee-o-kuk for 300 dollars, and that it was the finest horse on the frontier, belonging either to red or white man. In a few minutes afterwards I was exhibiting several of my paintings of buffalo-hunts, and describing the modes of slaying them with bows and arrows, when I made the assertion which I had often been in the habit of making, that there were many instances where the arrow was thrown entirely through the buffalo’s body; and that I had several times witnessed this astonishing feat. I saw evidently by the motions of my audience, that many doubted the correctness of my assertion; and I appealed to _Kee-o-kuk_, who rose up when the thing was explained to him, and said, that it had repeatedly happened amongst his tribe; and he believed that one of his young men by his side had done it. The young man instantly stepped up on the bench, and took a bow from under his robe, with which he told the audience he had driven his arrow quite through a buffalo’s body. And, there being forty of the Sioux from the Upper Missouri also present, the same question was put to them, when the chief arose, and addressing himself to the audience, said that it was a thing very often done by the hunters in his tribe. LETTER—No. 57. FORT MOULTRIE, _SOUTH CAROLINA_. Since the date of my last Letter, I have been a wanderer as usual, and am now at least 2000 miles from the place where it was dated. At this place are held 250 of the Seminolees and Euchees, prisoners of war, who are to be kept here awhile longer, and transferred to the country assigned them, 700 miles West of the Mississippi, and 1400 from this. The famous _Os-ce-o-la_ is amongst the prisoners; and also _Mick-e-no-pah_, the head chief of the tribe, and _Cloud_, _King Phillip_, and several others of the distinguished men of the nation, who have celebrated themselves in the war that is now waging with the United States’ Government.
