DEVIL'S LAKE

Any of the noble rivers and secluded lakes of Wisconsin were held in esteem or fear by the northern tribes, and it was the now-forgotten events and superstitions connected with them, not less than the frontier tendency for strong names, that gave a lurid and diabolical nomenclature to parts of this region. Devils, witches, magicians, and manitous were perpetuated, and Indians whose prowess was thought to be supernatural left dim records of themselves here and there—as near the dells of the Wisconsin, where a chasm fifty feet wide is shown as the ravine leaped by chief Black Hawk when flying from the whites. Devil's Lake was the home of a manitou who does not seem to have been a particularly evil genius, though he had unusual power. The lake fills what is locally regarded as the crater of an extinct volcano, and the coldness and purity kept by the water, in spite of its lacking visible inlets or outlets, was one cause for thinking it uncanny.

This manitou piled the heavy blocks of Devil's Door-Way and set up Black Monument and the Pedestalled Bowlder as thrones where he might sit and view the landscape by day—for the Indians appreciated the beautiful in nature and supposed their gods did, too—while at night he could watch the dance of the frost spirits, the aurora borealis. Cleft Rock was sundered by one of his darts aimed at an offending Indian, who owed his life to the manitou's bad aim. The Sacrifice Stone is shown where, at another time, a girl was immolated to appease his anger. Cleopatra's Needle, as it is now called, is the body of an ancient chief, who was turned into stone as a punishment for prying into the mysteries of the lake, a stone on East Mountain being the remains of a squaw who had similarly offended. On the St. Croix the Devil's Chair is pointed out where he sat in state. He had his play spells, too, as you may guess when you see his toboggan slide in Weber Canon, Utah, while Cinnabar Mountain, in the Yellowstone country, he scorched red as he coasted down.

The hunter wandering through this Wisconsin wilderness paused when he came within sight of the lake, for all game within its precincts was in the manitou's protection; not a fish might be taken, and not even a drop of water could be dipped to cool the lips of the traveller. So strong was this fear of giving offence to the manitou that Indians who were dying of wounds or illness, and were longing for a swallow of water, would refuse to profane the lake by touching their lips to it.
