At the western extremity of the earth, which is presumed to be a circular plain surrounded by water, is a high mountain, on the summit of which is a beautiful mound. On this mound is the palace of this family of gods. The palace opens toward each of the four cardinal points, and at each doorway is stationed a watcher. A butterfly stands at the east entrance, a bear at the west, a reindeer at the north, and a beaver at the south. Except the head, each of these wakan sentries is enveloped with scarlet down of the most exquisite softness and beauty.
