and he spent many a happy year as king in Tir na n-Og. At last he said to his wife: "I wish I could be in Erin to-day to see my father and his men."
"If you go," said his wife, "and set foot on the land of Erin, you 'll never come back here to me, and you 'll become a blind old man. How long do you think it is since you came here?"
"About three years," said Oisin.
"It is three hundred years," said she, "since you came to this kingdom with me. If you must go to Erin, I 'll give you this white steed to carry you; but if you come down from the steed or touch the soil of Erin with your foot, the steed will come back that minute, and you 'll be where he left you, a poor old man."
"I 'll come back, never fear," said Oisin. "Have I not good reason to come back? But I must see my father and my son and my friends in Erin once more; I must have even one look at them."
She prepared the steed for Oisin and said, "This steed will carry you wherever you wish to go."
Oisin never stopped till the steed touched the soil of Erin; and he went on till he came to Knock Patrick in Munster, where he saw a man herding cows. In the field, where the cows were grazing there was a broad flat stone.
"Will you come here," said Oisin to the herdsman, "and turn over this stone?"
