One day the boys came to their mother, as she was weaving mats. "Who is. our father?" they asked. "We have no one to run to when he returns from the hunt, or from war, to shout to him."
The mother answered: "In the morning, look toward the sunrise and you will see a white Cloud standing upright. He is your father."
"Can we visit our father?" they asked.
"Yes," said their mother. "You may visit him, but you must make the journey without stopping. First you will reach Wind, who is your father's eldest brother. Behind him you will find your father."
The boys travelled four days and came to the house of Wind.
"Are you our father?" they asked.
"No, I am your Uncle," answered Wind." Your father lives in the next house. Go on to him."
They travelled on to Cloud. But Cloud drove them away. He said, "Go to your uncle Wind. He will tell you something." But Wind sent them back to Cloud again. Thus the boys were driven away from each house four times.
Then Cloud said to them, "Prove to me you are my sons. If you are, you can do what I do."
The younger boy sent chain lightning across the sky with sharp, crackling thunder. The elder boy sent the heat lightning with its distant rumble of thunder.
