In their external form, the Onktehi are said to resemble the ox, only that they are of immense proportions. This god has power to extend his horns and tail so as to reach the skies. These are the organs of his power. The dwelling place of the male is in the water, and the spirit of the female animates the earth. Hence, when the Dakota seems to be praying, chanting or offering sacrifices to the water or to the earth, it is to this family of the gods that the worship is rendered. They address the male as grandfather, and the female as grandmother. Hence, also, it is probably, that the bubbling springs of water are called the “breathing places of the wakan.” Though not the same in form, and though destitute of the trident, the horse, and the dolphin, yet, because he rules in the watery worlds as Neptune did in the Mediterranean sea, it may not be out of place to denominate him the Neptune of the Dakotas. This god has power to issue from his body a wakan influence which is irresistible even by the superior gods. This missive influence is termed _tonwan_, which word will frequently recur as we proceed. This power is common to all the Taku-Wakan. This tonwan influence, it is claimed, is infused into each medicine-sack which is used in the medicine dance. One of these gods, it is believed, dwells under the Falls of St. Anthony, in a den of awful dimensions, and which is constructed of iron. 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 Dakotas as “Taku wakan tipi,” the dwelling place of the gods. It is believed that one of this family of divinities dwells there. Not many years since, at the breaking up of the ice in the Mississippi river, it gorged and so obstructed the channel between the falls and Fort Snelling, that the water in a few hours rose very high. When the channel was opened by pressure, of course, the rush of water “carried all before it.” A cabin which stood on the low bank under the falls, was carried away with a soldier in it, who was never heard of afterwards. It is universally believed by the worshippers of the god in question, that the occurrence was caused by one of these gods passing down the river, who took the soldier for his evening meal, as they often feast on human spirits—_wicanagi_. On the morning of July 4, 1851, at Traverse des Sioux, Robert Hopkins, a missionary of the American board to the Dakotas was drowned in the Minnesota river. It was the general belief and talk among the Dakotas, who were acquainted with the facts, that this god destroyed his life and ate his soul—nagi—because he had spoken against his worship in the medicine-dance.
