Karusakaibo had made the world but had not created men. One day Dairru, the armadillo, offended the creator and was forced to take refuge in a hole in the ground. Karusakaibo blew into the hole and stamped his foot on the earth. Daiiru was blown out of the hole by the rush of air. He reported that people were living in the earth. He and Karusakaibo made a cotton rope and lowered it into the hole. The people began to climb out. When half of them had emerged, the rope broke and half remained underground, where they still live. The sun passes through their country from west to east when it is night on the earth; the moon shines there when the earth has moonless nights.
