The old man gave him plenty to eat and to drink, and, when he was satisfied, he gave him a little white garron, and said, “Give the garron his head, and when he stops look up into the air, and you will see three swans as white as snow. Those are the three daughters of the King of the Black Desert. There will be a green napkin in the mouth of one of them: that is the youngest daughter, and there is not anyone alive except her who could bring you to the house of the King of the Black Desert. When the garron stops you will be near a lake. The three swans will come to land on the brink of that lake, and they will make three young women of themselves, and they will go into the lake swimming and dancing. Keep your eye on the green napkin, and when you get the young women in the lake, go and get the napkin, and do not part with it. Go into hiding under a tree, and when the young women will come out, two of them will make swans of themselves, and will go away in the air. Then the youngest daughter will say, “I will do anything for him who will give me my napkin.” Come forward then and give her the napkin, and say there is nothing you want but to bring you to her father’s house, and tell her you are a king’s son from a powerful country.”
The King’s son did everything as the old man desired him, and when he gave the napkin to the daughter of the King of the Black Desert, he said, “I am the son of O’Conor, King of Connaught. Bring me to your father. Long am I seeking him.”
“Would not it be better for me to do something else for you?” said she.
“I do not want anything else,” said he.
“If I show you the house will you not be satisfied?” said she.
“I will be satisfied,” said he.
“Now,” said she, “upon your life do not tell my father that it was I who brought you to his house, and I shall be a good friend to you; but let on,” said she, “that you have great powers of enchantment.”
“I will do as you say,” says he.
Then she made a swan of herself, and said, “Leap up on my back and put your hands under my neck, and keep a hard hold.”
