"'That day is far, far away,' said Cheiron, who could read the future. 'But it will come. Eagles fly from the nest, so must you fly hence. Go, but promise me this. Speak kindly to each one that you meet and keep always your promises.' "'I promise you and I will perform,' said Jason, and he bade Cheiron farewell. Then he hurried down the mountain-side, through the sweet-smelling groves where grew the wild thyme and arbutus, beyond the vineyards green in the sun, and the olive groves in fragrant bloom. He came to the river bank, a stream swollen with spring rains and foaming to the sea. Upon the bank was an old woman, wrinkled and gray, and she cried to Jason, "'Good sir, carry me across this stream.' "Jason looked at her, and at first he thought to leave her, for the stream was broad and it roared over cruel rocks and was heavy with the mountain's melting snow. But she cried pitifully, "'Fair youth, for Hera's sake, carry me across.' "Now Hera was queen of all the gods who lived on Olympus, and Jason said, "'For Hera's sake will I do much. Cling upon my back and I will carry you across. That I promise you.' Then he remembered Cheiron's word and was glad he had answered her softly. He struggled through the foam, but the old woman was heavy and she clung about his neck and seemed to grow heavier. He buffeted the waves and struggled, and twice he thought he must let the old woman go, but he remembered his promise and held her fast, and at last he reached the farther shore and scrambled up the bank. And as he gently set his burden down, lo! she was a fair young woman, and she smiled upon him and said, "'I am that Hera for whose sake you have done this deed of kindness. I will repay you, for whenever you need help call upon me, and I will not forget you.' Then she rose up from the earth into the clouds, and with awe and wonder, Jason watched her fade from his sight. "Then he went on to Iolchis, but he walked slowly, for he had lost one sandal in the flood. He went into the city and spoke with the king, demanding his realm, and the king was afraid of him, for soothsayers had foretold that a man wearing one sandal should take the kingdom away from him. "But the king spoke to him kindly and gave him food, and said to him, 'Your father gave me the kingdom of his own free will. See him and ask him if this is not true.' Jason said that he would do so, and he ate with his uncle, and at last the king said, "'There is a man in my kingdom whom I am afraid will cause me trouble if he stays here. What would you do with him were you I? I ask because I know you are wise.' "'I think I would send him to bring home the Golden Fleece,' said Jason. "'Will you go?' said the king, and Jason saw that he was caught in a trap, and that his uncle had meant him.
