Birth of Fin MacCumhail and Origin of the Fenians of Erin
Next day she came to a great oak tree. Then she hired a man to cut out a chamber in the tree.
When all was finished, and there was a nice room in the oak for herself and her grandson, and a whelp of the same age as the boy, and which she had brought with her from the castle, she said to the man: "Give me the axe which you have in your hand, there is something here that I want to fix."
The man gave the axe into her hand, and that minute she swept the head off him, saying: "You'll never tell any man about this place now." One day the whelp ate some of the fine chippings (bran) left cut by the carpenter from the inside of the tree. The old woman said: "You'll be called Bran from this out."
All three lived in the tree together, and the old woman did not take her grandson out till the end of five years; and then he couldn't walk, he had been sitting so long inside.
When the old grandmother had taught the boy to walk, she brought him one day to the brow of a hill from which there was a long slope. She took a switch and said: "Now, run down this place. I will follow and strike you with this switch, and coming up I will run ahead, and you strike me as often as you can."
The first time they ran down, his grandmother struck him many times. In coming up the first time, he did not strike her at all. Every time they ran down she struck him less, and every time they ran up he struck her more.
They ran up and down for three days; and at the end of that time she could not strike him once, and he struck her at every step she took. He had now become a great runner.
When he was fifteen years of age, the old woman went with him to a hurling match between the forces of his grandfather and those of a neighboring king. Both sides were equal in skill; and neither was able to win, till the youth opposed his grandfather's people. Then, he won every game. When the ball was thrown in the air, he struck it coming down, and so again and again,—never letting the ball touch the ground till he had driven it through the barrier.
