So Childe Rowland said good-bye to the good queen, his mother, and went to the cave of the Warlock Merlin. “Once more, and but once more,” he said to the Warlock, “tell how man or mother's son may rescue Burd Ellen and her brothers twain.” “Well, my son,” said the Warlock Merlin, “there are but two things, simple they may seem, but hard they are to do. One thing to do, and one thing not to do. And the thing to do is this: after you have entered the land of Fairy, whoever speaks to you, till you meet the Burd Ellen, you must out with your father's brand and off with their head. And what you've not to do is this: bite no bit, and drink no drop, however hungry or thirsty you be; drink a drop, or bite a bit, while in Elfland you be and never will you see Middle Earth again.” So Childe Rowland said the two things over and over again, till he knew them by heart, and he thanked the Warlock Merlin and went on his way. And he went along, and along, and along, and still further along, till he came to the horse-herd of the King of Elfland feeding his horses. These he knew by their fiery eyes, and knew that he was at last in the land of Fairy. “Canst thou tell me,” said Childe Rowland to the horse-herd, “where the King of Elfland's Dark Tower is?” “I cannot tell thee,” said the horse-herd, “but go on a little further and thou wilt come to the cow-herd, and he, maybe, can tell thee.” Then, without a word more, Childe Rowland drew the good brand that never struck in vain, and off went the horse-herd's head, and Childe Rowland went on further, till he came to the cow-herd, and asked him the same question. “I can't tell thee,” said he, “but go on a little farther, and thou wilt come to the hen-wife, and she is sure to know.” Then Childe Rowland out with his good brand, that never struck in vain, and off went the cow-herd's head. And he went on a little further, till he came to an old woman in a grey cloak, and he asked her if she knew where the Dark Tower of the King of Elfland was. “Go on a little further,” said the hen-wife, “till you come to a round green hill, surrounded with terrace-rings, from the bottom to the top; go round it three times, widershins, and each time say: Open, door! open, door! And let me come in. and the third time the door will open, and you may go in.” And Childe Rowland was just going on, when he remembered what he had to do; so he out with the good brand, that never struck in vain, and off went the hen-wife's head. Then he went on, and on, and on, till he came to the round green hill with the terrace-rings from top to bottom, and he went round it three times, widershins, saying each time: Open, door! open, door! And let me come in. And the third time the door did open, and he went in, and it closed with a click, and Childe Rowland was left in the dark.
