No. 16, 122°, discharges 2 gallons per minute. No. 17. The uppermost on the creek, 126°. No. 18, 126°; 19, 128°; 20, 130°; 21, 136°; 22, 140°. All these are large springs, and rise at an elevation of at least 100 feet above the creek. In the same area are several others, and what is more remarkable, several cold ones. In any of the hot springs I observed bubbles rising in rapid succession, but could not discover any perceptible smell from them. Not only confervas and other vegetables grow in and about the hottest springs, but great numbers of little insects are seen constantly sporting about the bottom and sides. Temperature of the water of the creek, above the springs, 46°. The entire quantity of water flowing in the creek after it receives the water of the hot springs, may be estimated at from 900 to 1000 gallons per minute.--JAMES. [40] Wilson must have been one of the transient residents common at this period; the first permanent settlers did not come until 1826 or 1828.--ED. [41] The temperature was, however, no more than sufficient to raise the mercury in Fahrenheit's thermometer to 160°. It has been represented by Bringier, in a paper published in Silliman's Journal, that "the heat of the water is 192° Fah." On what observations this assertion rests we know not. See "The American Journal of Science and Arts," Vol. iii. No. I. p. 29.--JAMES. [42] Little River rises in north-western Polk County, crosses the state line into Indian Territory, and re-enters Arkansas to separate Sevier and Little River counties; it falls into Red River at the south-east corner of the latter county. Rolling Fork and Cossetot rise in southern Polk County and flow south through Sevier. Mountain Fork is one of several small streams the waters of which unite in Indian Territory to form Little River.--ED. [43] Nuttall's Travels, p. 150.--JAMES. _Comment by Ed._ Page 211 of reprint in our volume xiii. [44] Ouachita River pursues an easterly course until it enters Hot Springs County; then it turns sharply to the south-west, changing direction again on leaving the county, and flowing south-south-east until it enters Louisiana. Fourche-au-Cadeau (now contracted to Caddo Creek) heads in Montgomery County, and flowing south-east meets the Ouachita on the northern line of Clark County. Cadeau is a corruption of Cadaux. Both words are French, the former meaning a gift, the latter being the plural of the name of an Indian tribe (Caddo in English) whose range included southwestern Arkansas. The stream is called Fourche des Cadaux (Fork of the Caddos) in Dunbar and Hunter's "Description of the Washita River" (_American State Papers_, "Indian Affairs," i, p. 731). At the south-east corner of Clark County is the mouth of the Little Missouri, which rises on the Polk-Montgomery county line, traverses Pike, and forms the southern line of Clark.--_Ed._
