"Well," said the frog, "if you promise me to do whatever I bid you for a whole night long, I'll tell you how to fill it."
So the girl agreed, and then the frog said:
"Stop it with moss and daub it with clay,
And then it will carry the water away";
and then it gave a hop, skip, and jump, and went flop into the Well of the World's End.
So the girl looked about for some moss, and lined the bottom of the sieve with it, and over that she put some clay, and then she dipped it once-again into the Well of the World's End; and this time the water didn't run out, and she turned to go away.
Just then the frog popped up its head out of the Well of the World's End, and said, "Remember your promise."
"All right," said the girl; for, thought she, "what harm can a frog do me?"
So she went back to her stepmother, and brought the sieve full of water from the Well of the World's End. The stepmother was angry as angry, but she said nothing at all.
That very evening they heard something tap-tapping at the door low down, and a voice cried out:
"Open the door, my hinny, my heart,
Open the door, my own darling;
Remember the words that you and I spoke,
At the World's End Well but this morning."
