On one occasion during the march, Mahéga availed himself of her mysterious acquirements, in a manner that reflected great credit upon his sagacity, at the same time that it increased, in a tenfold degree, the awe with which she had inspired him and his adherents. They had made their usual halt at noon, by the side of a small stream; Prairie–bird and her faithful Lita were sheltered from the burning rays of the sun by an arbour of alder–branches, which the Osages had hastily, but not inconveniently, constructed; Mahéga and his warriors being occupied in eating the dainty morsels of meat afforded by a young buffalo cow killed on the preceding day, when a large band of Indians appeared on the brow of a neighbouring hill, and came down at full speed towards the Osage encampment Mahéga, without manifesting any uneasiness, desired his men to pile a few of their most valuable packages within the arbour of Olitipa, and to form themselves in a semicircle around, for its protection, their bows and rifles being ready for immediate use. Having made these dispositions, he waited the approach of the strangers, quietly cutting his buffalo beef, and eating it, as if secure of their friendly intentions. Having come within a hundred yards, they drew in their bridles on a signal from their leader, who seemed disposed to take a more deliberate survey of the party. From their appearance Mahéga knew that they must belong to one of the wild roving tribes who hunt between the sources of the Platte and Arkansas rivers, but the name or designation of their tribe he was at first unable to make out. Their weapons were bows and arrows, short clubs, and knives; their dress, a hunting–shirt of half–dressed skin, a centre–cloth of the same material, and mocassins on their feet, leaving the legs entirely bare; the leader had long hair, clubbed at the back of his head, and fastened with sinew–strings round a wooden pin, to which were attached several stained feathers, which danced in the wind, and heightened the picturesque effect of his costume.
A rapid glance sufficed to show him that the new comers, although apparently busied about their meal without distrust, were not only well armed but ready for immediate service; nor did his eye fail to note the martial bearing and gigantic proportions of Mahéga, who sat like a chief expecting the approach of an inferior.
Influenced by these observations, the leader of the roving band resolved that the first intercourse at least should be of a peaceful nature, prudently reflecting, that as his own numbers were far superior, the nearer the quarters the greater would be their advantage. Having uttered a few brief words to his followers, he advanced with a friendly gesture towards Mahéga, and the following dialogue took place, in the ingenious language of signs before referred to:—
Mahéga.—“What tribe are you?”
Leader.—“Ari–ca–rá.[51] What are you, and whither going?”
M.—“Washashee, going to the mountains.”
L.—“What seek you there?”
M.—“Beaver, otter, and grisly bear–skins.”
L.—“Good. What is in the green–branch wigwam?”
M.—“Great Medicine—let the Aricará beware.” To this the chief added the sign usually employed for their most solemn mysteries.
