It is not so easy to see how this Being was developed out of ancestor-worship, of which we find no traces among Pawnees. For ancestor-worship among the Sioux, it is usual to quote a remark of one Prescott, an interpreter: 'Sometimes an Indian will say, "Wah negh on she wan da," which means, "Spirits of the dead have mercy on me." Then they will add what they want. That is about the amount of an Indian's prayer.'[10] Obviously, when we compare Mr. Grinnell's account of Pawnee religion, based on his own observations, and those of Major North, and Mr. Dunbar, who has written on the language of the tribe, we are on much safer ground, than when we follow a contemptuous, half-educated European. The religion of the Blackfoot Indians appears to be a ruder form of the Pawnee faith. Whether the differences arise from tribal character, or from decadence, or because the Blackfoot belief is in an earlier and more backward condition than that of the Pawnees, it is not easy to be certain. As in China, there exists a difficulty in deciding whether the Supreme Being is identical with the great nature-god; in China the Heaven, among the Blackfeet the Sun; or is prior to him in conception, or has been, later, substituted for him, or placed beside him. The Blackfoot mythology is low, crude, and, except in tales of Creation, is derisive. As in Australia, there is a specific difference of tone between mythology and religion. The Blackfoot country runs east from the summit of the Rocky Mountains, to the mouth of the Yellowstone river on the Missouri, then west to the Yellowstone sources, across the Rocky Mountains to the Beaverhead, thence to their summit. As to spirits, the Blackfeet believe in, or at least tell stories of, ghosts, which conduct themselves much as in our old-fashioned ghost stories. They haunt people in a rather sportive and irresponsible way. The souls or shadows of respectable persons go to the bleak country called the Sand Hills, where they live in a dull, monotonous kind of Sheol. The shades of the wicked are 'earth-bound' and mischievous, especially ghosts of men slain in battle. They cause paralysis and madness, but dread interiors of lodges; they only 'tap on the lodge-skins.' Like many Indian tribes, the Blackfeet have the Eurydice legend. A man grieving for his dead wife finds his way to Hades, is pitied by the dead, and allowed to carry the woman back with him, under certain ritual prohibitions, one of which he unhappily infringes. The range of this deeply touching story among the Red Men, and its close resemblance to the tale of Orpheus, is one of the most curious facts in mythology. Mr. Grinnell's friend Young Bear, when lost with his wife in a fog, heard a Voice, 'It is well. Go on, you are going right.' 'The top of my head seemed to lift up. It seemed as if a lot of needles were running into it.... This must have been a ghost.' As the wife also heard the Voice it was probably human, not hallucinatory.
