"Oh! this is my brother, who has come to see me," said she.
"If he's your brother, he's welcome," said the man.
They supped, and then slept till morning. When the man of the castle was going out again, in the form of a great salmon, he turned to the boy and said: "You'd better stay here with us a while."
"I cannot," said the boy. "I made a vow never to sleep three nights in one house till I had seen my three sisters. I must go on now and find my third sister."
The salmon then took off a piece of his fin and gave it to the boy, saying: "If any difficulty meets you, or trouble comes on you, call on what salmons are in the sea to come and help you."
They parted. The boy put on his cloak of darkness, and away he went, more swiftly than any wind. He never stopped till he was hungry and thirsty. Then he sat down, took off his cloak of darkness, spread the cloth of plenty, and ate his fill; when he had eaten, he went on again till near sundown, when he saw the castle where his third sister lived. All three castles were near the sea. Neither sister knew what place she was in, and neither knew where the other two were living.
The third sister took her brother in just as the first and second had done, telling him not to wonder at anything he saw.
They were not long inside when a roaring noise was heard, and in came the greatest eagle that ever was seen. The eagle hurried upstairs, and soon came down a man.
"Who is that stranger there with you?" asked he of the wife. (He, as well as the ram and salmon, knew the boy; he only wanted to try his wife.)
"This is my brother, who has come to see me."
