When the dragon's teeth were planted, iron men grew up.

They always killed the one who had planted them.

The king wanted the bulls to kill Jason.

He said, "If the bulls do not kill him the iron men will."

The king had a daughter named Medea. She saw Jason was a brave young man and did not want him killed.

She knew how to help him. She stepped into her carriage, which was pulled by flying snakes.

Then Medea flew through the air. She went to hills and creeks and picked all kinds of flowers.
