Sunday, 30th. About sunrise a dense fog intercepted the view of surrounding scenery, which was soon dissipated as we moved on, exhibiting all the variety of partially revealed and unnaturally enlarged objects, so familiar to observers of rural sights. At noon, a beautiful natural grove of cotton-wood, lining a ravine in which was some cool but stagnant water near the bank of the river, invited us to repose during the oppressive mid-day heat. We had hardly stripped our horses of their baggage, and betaken ourselves to our respective occupations, when a voice from the opposite bank of the river warned us of the proximity of Indians, who had been until now unseen. Nine Indians soon appeared, and crossed the river to our camp. They proved to be an Arrapaho war-party of eight men and a squaw, of whom one was a Kiawa.[100] This party informed us, that they had left the Bear Tooth's party on a tributary of this river, at the distance of about half a day's journey from us, moving upwards. As no apprehension of mischief was entertained from so small a party, they were invited to encamp near us for the remainder of the day; to which, urged by curiosity, and perhaps by the hope of receiving some presents, they readily assented. The squaw busied herself in erecting a little bowery, of a sufficient size to contain herself and her {57} husband, who we afterwards discovered to be a personage of some eminence in their mystic arts. Having supplied our guests with a pipe of some tobacco, we resumed our occupations. Our attention was, however, diverted to the young Kiawa warrior, who had the presumption to seize the Kaskaia horse which was purchased of the Calf Indian, loose him from the stake around which he was grazing, and having the further audacity to lead him near to our tents, proceeded to make a noose in the halter, which he placed over the mouth of the animal, that patiently submitted to his operations. This sudden subjugation of the horse was a subject of more surprise to us than the outrageous attempt of the Indian, as he had hitherto resisted all our endeavours to accomplish the same object, whether conciliatory or forcible. It seemed to corroborate the truth of the observation, that the horse readily distinguishes the native from the white man by his acute sense of smelling. The intention of the Indian to take possession of the horse was now manifest, and one of our party stepped forward and seized the halter near the head of the animal; but the Indian, who held the other extremity of the halter, betrayed no symptoms of fear, or of an intention to relinquish a possession which he had thus partially obtained: he looked sternly at his antagonist, and asserted his right to the horse, inasmuch as he had, he said, formerly owned him, and meant now to repossess him. Supposing that this altercation might eventuate unpleasantly, the remainder of our party stood prepared to repulse any attempt which
