A small number of a differently coloured and rather larger bean was intermixed with them.[101] The squaw had in her possession a quantity of small flat blackish cakes, which on tasting we found very palatable. Having purchased some of them, we ascertained that they were composed of the wild cherry, of which both pulp and stone were pounded together, until the latter is broken into fragments, then mixed with grease, and dried in the sun. Not choosing to rely implicitly on the good faith of the strangers, however emphatically expressed, the sentinel was directed to look well to them, and also to keep the horse in question constantly in view during the night, and to alarm us upon the occurrence of any suspicious movements. All, however, remained quiet during the night, and in the morning, Monday 31st, we resumed our journey. The river now considerably dilates, and is studded with a number of small islands, but the timber that skirts its stream is still less abundant, and more scattered. The alluvial formation affords a moderate growth of grass, but the general surface of the country is flat, sterile, and uninteresting. The day was cloudy with an E. S. E. wind, which at night brought some rain. Tuesday, August 1st. Set out late; and after having travelled about two miles, a horseman armed with a spear was seen on the bluffs, at the distance {60} of about a quarter of a mile, who, after gazing at our line for a short time, disappeared. Our Pawnee interpreters being at a considerable distance in the rear, Julien was sent forward to reconnoitre. He mounted the bluff to the general level of the country, and abruptly halted his horse within our view, as if appearances before him rendered precaution necessary. The Indian again came in sight, and in full career rushed towards him, passed him, and wheeling, halted his horse. Many other Indians then appeared, who surrounded Julien, and after a short and hurried conference, they dashed at full speed down the steep bank of the bluff to meet us, the whole in concert singing the scalp song. So adventurous and heedless was this movement, that one of the horses stumbled and fell with great violence, and rolled to the bottom. His rider, no doubt prepared for such an accident, threw himself in the instant from his seat, so as to fall in the most favourable manner, and avoid the danger of being crushed by the horse; not the slightest attention was bestowed upon him by his companions, and indeed the disaster, however serious it first appeared, hardly interrupted his song. His horse being but little injured, he almost immediately regained his saddle, and came on but little in the rear of the others, who now had mingled with our party, shaking us by the hand with a kind of earnest familiarity not the most agreeable. We needed no additional information to convince us that this was a war-party; their appearance was a sufficient evidence of the nature of their occupation.
