Once, the Sun and his sister, the Moon, lived together in a wigwam in the east. The Sun dressed himself to go hunting and took his bow and arrows and left. He was absent such a long time that when his sister came out into the sky to look for her brother, she became alarmed. She traveled twenty days looking for the Sun. Finally he returned, bringing with him a bear which he had shot.
The Sun’s sister still comes up into the sky and travels for twenty days. Then she dies, and for four days nothing is seen of her. At the end of that time, however, she returns to life and travels twenty days more.
