{194} On arriving at the Arkansa Captain Bell was detached with a small party to ascend along the river as far as it was practicable to travel with horses, and was able to ascend nearly thirty miles, when his further progress was intercepted by the proximity of the hills to the river. Having descended the Arkansa about one hundred miles to the point whence it was judged expedient to strike upon a southwardly course in quest of the source of the Red river, the party was formed into two detachments; the one to proceed down the Arkansa, under the direction of Captain Bell, and the other to accompany me, with the view of exploring the country southwardly to Red river, and thence down its valley to the upper settlements thereon. Captain Bell's party, with the exception of three soldiers last mentioned in the foregoing list, who deserted on the march, arrived in safety at Belle Point, their place of destination, having performed the duties assigned them. On separating from Captain Bell, the detachment under my direction proceeded southwardly in view of the mountains about one hundred and fifty miles, and arrived at a creek, having a southwardly course, which we took to be tributary to Red river. Having travelled down its valley about two hundred miles, we fell in with a party of Indians of the nation of Kaskaias, or Bad-hearts, who gave us to understand that the stream along which we were travelling was Red river. We accordingly continued our march down the river several hundred miles further; when, to our no small disappointment, we discovered that it was the Canadian of the Arkansa, instead of Red river, that we had been exploring. Our horses being nearly worn out with the fatigue of our long journey, which they had to perform bare-footed, and the season being too far advanced to admit of retracing our steps and going again in quest of the source of Red river with the possibility of exploring it before the commencement {195} of winter, it was deemed advisable to give over the enterprize for the present, and make our way to the settlements on the Arkansa. We were led to the commission of this mistake in consequence of our not having been able to procure a guide acquainted with this part of the country. Our only dependence, in this respect, was upon Pike's map, which assigns to the head-waters of the Red river the apparent locality of those of the Canadian. We continued our march, therefore, and arrived at Belle Point on the Arkansa on the 13th September, four days after the arrival of Captain Bell and his party.
