Note 52 — [273] CHAPTER IV [XI]

The stream in question was not a branch of Red River, but, as appears later, a tributary of the Canadian branch of the Arkansas (see Nuttall's Journal, in our volume xiii, note 188). The course of the party after leaving the Purgatory carried them east of that portion of the Canadian which flows south near the base of the mountains, and brought them to some creek which joins the Canadian near the Texas line. A stream in this locality, presumably the one descended, has been named Major Long's Creek. The map is therefore wrong in placing the route of the party along the portion of the upper course of the Canadian, which is thereon marked "Rio Mora" (Raspberry River). Moreover, the Mora is not the main stream of the Canadian, as the map indicates, but a tributary from the west.

The sources of Red River lie near the Texas boundary, in the Staked Plains, south of the Canadian. Long's expedition was the third ineffectual effort of the federal government to discover them. In 1806, Captain Richard Sparks attempted to ascend the river, but was stopped by Spanish cavalry (see chapter iii in our volume xvii). In the same year Lieutenant Z. M. Pike ascended the Arkansas with instructions to find the head of the Red and descend that stream. He mistook for the Red, first the Arkansas itself and then the Rio Grande, and like Sparks was prevented by the Spaniards from carrying his exploration to a successful close. Red River was not explored to its sources until 1852, when it was ascended by a party under Capt. Randolph B. Marcy, of the Fifth Infantry. An expedition under General McLeod, which left Austin, Texas, in June, 1841, and was captured by Mexicans, is thought to have visited the sources of Red River, but it furnished no topographical data which could be relied on.

Long's party approached within perhaps a hundred and fifty miles of Santa Fé.—Ed.
