§ 253. Dwarfs or elves are probably referred to in the following; This [_i. e._ the object sought by Lewis and Clarke’s party] was a large mound in the midst of the plain, about N. 20° W. from the mouth of Whitestone River, from which it is 9 miles distant. The base of the mound is a regular parallelogram, the longest side being about 300 yards, the shorter 60 or 70; from the longest side it rises with a steep ascent from the north and south to the height of 65 or 70 feet, leaving on the top a level plain of 12 feet in breadth and 90 in length. The north and south extremities are connected by two oval borders, which serve as new bases, and divide the whole side into three steep but regular gradations from the plain. The only thing characteristic in this hill is its extreme symmetry, and this, together with its being wholly detached from the other hills, which are at the distance of 8 or 9 miles, would induce a belief that it was artificial; but as the earth and loose pebbles which compose it are arranged exactly like the steep grounds on the borders of the creek, we concluded from this similarity of texture that it might be natural. But the Indians have made it a great article of their superstition; it is called the Mountain of the Little People, or Little Spirits, and they believe that it is the abode of little devils in the human form, of about 18 inches high, and with remarkably large heads; they are armed with sharp arrows, with which they are very skillful, and are always on the watch to kill those who should have the hardihood to approach their residence. The tradition is that many have suffered from these little evil spirits, and, among others, three Maha Indians fell a sacrifice to them a few years since. This has inspired all the neighboring nations, Sioux, Mahas, and Ottoes, with such terror that no consideration could tempt them to visit the hill.[188] BOGS.
