The children then went home to wait for their father. It was a long journey, for they had run far. But their father never came. Months and months they waited, but he did not come, and they grew up to be great magicians and very powerful among their tribe. At last, by their magic power, they learned what had happened to their father. Their stepmother's body continued to follow him as he ran towards the west. It followed him for many days. Then by his magic power, which the vision of his dead wife had brought to him, he changed himself into the Sun, and went to live with his wife in the sky-country. But the old witch-woman also had magic power, and she changed herself into the Moon and followed him to the land of the stars. And there she still pursues him. And while he keeps ahead of her and she cannot catch him, night follows day in all the world. But if she overtakes him she will kill him, and day will disappear and night shall reign for evermore upon the earth. And the Blackfeet of the plains pray that he will always keep in front in the race with his former witch-wife, so that there may be always Night and Day in succession in all the land.
