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 fine and
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;
Mind you the words that you and I spoke,
Down in the meadow, at the World's End Well."

"Whatever can that be?" cried out the stepmother, and the girl had to
tell her all about it, and what she had promised the frog.

"Girls must keep their promises," said the stepmother. "Go and open
the door this instant." For she was glad the girl would have to obey a
nasty frog.
