We have, as Mr Wilson tells the story, the complete _dissection_ of a myth; we see how a legend arises, or may arise, partly from the most trivial causes, and partly from generous impulses and high imaginations. Between the Minnesota and the Missouri rivers there stands a bold perpendicular cliff, “beautifully marked with distinct horizontal layers of light grey and rose or _flesh-coloured_ quartz.” Near this a famous red pipe-stone is procured; a material, we presume, better fitted than any other for making pipes. Traces of both ancient and modern excavation prove that it has been the resort, during many generations, of Indian tribes, seeking this famous red pipe-stone. A spot to which independent tribes came for this purpose, and for this only, became neutral ground; became a spot on which they might meet in peace—perhaps to discuss their points of difference. But in process of time it became a sacred spot, and the peace between hostile tribes was preserved by a religious sanction. There are marks on the rock resembling the track of a large bird. These were converted into the footsteps of the Great Spirit. The Great Spirit, therefore, at one time descended upon the rock and taught—what else could he be supposed to teach?—the sacred neutrality of the spot, and the privilege and duty of all tribes to renew their pipes there, and especially the calumet, or pipe of peace. The last version of the tradition runs thus:— “Many ages,” say the Sioux, “after the red men were made, when all the different tribes were at war, the Great Spirit called them all together at the Red Rocks. He stood on the top of the rocks, and the red nations were assembled in infinite numbers in the plain below. He took out of the rock a piece of the red stone, and made a large pipe. He smoked it over them all; told them that it was part of their flesh; that though they were at war they must meet at this place as friends; that it belonged to them all; that they must make their calumets from it, and smoke them to him whenever they wished to appease him or get his goodwill. The smoke from his big pipe rolled over them all, and he disappeared in the cloud.”
