§ 108. “The word Unkteḣi defies analysis, only the latter part giving us the idea of _difficult_ [sic], and so nothing can be gathered from the name itself of the functions of these gods. But Indian legend generally describes the genesis of the earth as from the water. Some animal, as the beaver [compare the Iowa and Oto Beaver gentes, Paça and Paqça.--J. O. D.] living in the waters, brought up, from a great depth, mud to build dry land.”[107] According to the Dakota cosmogony, this was done by the Unkteḣi, called in the Teton dialect Ŭñktcexila or Uŋkćeġila. (Compare the Winnebago, Waktceqi ikikaratcada or water-monster gens, and the Wakandagi of the Omaha and Ponka, see §§ 7, 77). § 109. The Iowa and Oto tribes have among their nikie names, Niwaⁿcike, Water Person, and Niwaⁿcikemi, Water Person Female. If these do not refer to the beaver, they may have some connection with the water monsters or deities. An Omaha told the author a Yankton legend about these gods of the waters. The wife of the special Unkteḣi coveted an Indian child and drew it beneath the surface of the river. The father of the child had to offer a white dog to the deity in order to recover his son; but the latter died on emerging from the water, as he had eaten some of the food of the Unkteḣi during his stay with the deity. After awhile the parents lost a daughter in like manner, but as she did not eat any of the food of the Unkteḣi, she was recovered after an offering of four white dogs.[108] Smet tells of offerings made by the Assiniboin to “the water” and “the land,” but it is probable that they were made to the Unkteḣi.[109] § 110. The Dakota pray to lakes and rivers, according to Riggs,[110] but he does not say whether the visible objects were worshiped or whether the worship was intended for the Unkteḣi supposed to dwell in those lakes and rivers. POWER OF THE UNKTEḢI. § 111. These gods have power to send from their bodies a wakan influence which is irresistible even by the superior gods. This influence is termed “tonwan.” This power is common to all the Taku Wakan. And it is claimed that this tonwan is infused into each mystery sack which is used in the mystery dance. A little to the left of the road leading from Fort Snelling to Minnehaha, in sight of the fort, is a hill which is used at present as a burial place. This hill is known to the Dakota as “Taku Wakan tipi,” the dwelling place of the gods. It is believed that one of the Unkteḣi dwells there. § 112. The Unkteḣi are thought to feed on the spirits of human beings, and references to this occur in the mystic songs. The mystery feast and the mystery dance have been received from these gods. The sacrifices required by them are the soft down of the swan reddened with vermilion, deer skins, dog, mystery feast and mystery dances.
