Of the Vaseau, or Boggy Bayou, and the Blue river, two considerable streams tributary to Red river, next above the Kiamesha, we have little information. They appear to enter like what are called the north and south forks of the Canadian, near the foot of the western slope of the Ozark mountains. Above these the principal tributary is the Faux Ouachita, or False Washita, from the north, which has been described to us (by Mr. Findlay, an enterprising hunter, whose pursuits often led him to visit its banks), as bearing a very near resemblance to the Canadian river of Arkansa.[69] We are as yet ignorant of the true position of the sources of Red river; but we are well assured the long received opinion, that its principal branch rises "about thirty or forty miles east of Santa Fé," is erroneous. Several persons have recently arrived at St. Louis in Missouri, from Santa Fé, and, among others, the brother of Captain Shreeves, who gives information of a large and frequented road, which runs nearly due east from that place, and strikes one of the branches of the Canadian, [and] that at a considerable distance to the south of this point in the high plain is the principal source of Red river. His account confirms an opinion we had previously formed, namely, that the branch of the Canadian explored by Major Long's party, in August 1820, has its sources near those of some stream which descends towards the west into the Rio Del Norte, and consequently that some other region must contain the head of Red river. From a careful comparison of all the information we have been able to collect, we are satisfied that the stream on which we encamped on the 31st of August [July] is the Rio Raijo [Rojo] of Humboldt, {177} long mistaken for the source of the Red river of Natchitoches, and that our camp of September [August] 2d was within forty or fifty miles east from Santa Fé. In a region of red clay and sand, where all the streams have nearly the colour of arterial blood, it is not surprising that several rivers should have received the same name; nor is it surprising that so accurate a topographer as the Baron Humboldt, having learned that a Red river rises forty or fifty miles east of Santa Fé, and runs to the east, should conjecture it might be the source of the Red river of Natchitoches. This conjecture (for it is no more) we believe to have been adopted by our geographers, who have with much confidence made their delineations and their accounts correspond to it.[70]
