"About thirty miles below the falls of St. Anthony, at which I arrived the tenth day after I left Lape Pepin, is a remarkable cave of an amazing depth. The Indians term it Wakon-teebe, that is, the Dwelling of the Great Spirit. The entrance into it is about four feet wide; the height of it fire feet. The arch within it is near fifteen feet high, and about thirty feet broad. The bottom of it consists of fine, clear sand. About twenty feet from the entrance begins a lake, the water of which is transparent, and extends to an unsearchable distance; for the darkness of the cave prevents all possibility of acquiring a knowledge of it. I threw a small pebble towards the interior parts of it with my utmost strength: I could hear that it fell into the water, and, notwithstanding that it was of so small a size, it caused an astonishing and horrible noise, that reverberated through all those gloomy regions. I found in this cave many Indian hieroglyphics, which appeared very ancient, for time had nearly covered them with moss, so that it was with difficulty I could trace them. They were cut in a rude manner upon the inside of the walls, which were composed of a stone so extremely soft, that it might easily be penetrated with a knife; a stone every where to be found near the Mississippi." _Carver's Travels_, p. 39, 40. Very many of the Western Indians believe that the Supreme Being has his residence in the Rocky Mountains; and some of them make him the Sun.--_Charlevoix_, ii, 180, 117. The Chippeways suppose the islands in Lake Superior to have been, from their first formation, the residence of the Great Spirit, and relate many stories of enchantment and magical tricks that had been experienced by such as were obliged, through stress of weather, to take shelter there.--See one of them further on. The Hurons believe that Michabou, the God of the Waters, and sometimes their Great Spirit, formerly dwelt at Michillimackinac where he was born. (5) _The thunder_.--p. 153. The Indians have but one way to account for atmospherical phenomena; it is always by the intervention of a Supreme or Spiritual Being of the earth, the air, or the waters. Thus they ascribe earthquakes to the moving of the Great Tortoise which bears the _Island_ (continent) on its back. They say he shakes himself or changes his position. The Missouri Indians believe earthquakes to be the effect of supernatural agency, connected like the thunder with the immediate operations of the Master of Life. Thunder and lightning impress them with inconceivable terror. Their opinions of the cause are various. Some take it for a voice of a particular species of men who fly in the air. Others say the noise comes from certain birds that are unknown to them. The Montagnais say it is the effort of a genius to bring up a snake which he hath swallowed; and they found this notion on observing that when the thunder falls upon a tree, it leaves something like, the shape of a snake.
