it wi' his knee;
And aye as he played, out o'er them a'.
O'er the kirk he gar'd it flee.
Burd Ellen round about the aisle
To seek the ba' has gane:
But she bade lang, and ay langer,
And she came na back again.
They sought her east, they sought her west,
They sought her up and down,
And wae were the hearts in merry Carlisle,
For she was nae gait found."

Merlin, the warlock, being consulted, told them that burd Ellen was
taken away by the fairies, and that it would be a dangerous task to
recover her if they were not well instructed how to proceed. The
instructions which Merlin gave were, that whoever undertook the quest
for her should, after entering elfland, kill every person he met till he
reached the royal apartments, and taste neither meat nor drink offered
to them, for by doing otherwise they would come under the fairy spell,
and never again get back to earth. Two of her brothers undertook the
journey, but disobeyed the instructions of the warlock, and were
retained in elfland. Child Rowland, her youngest brother, then arming
himself with his father's claymore, _excalibar_--that never struck in
vain--set out on the dangerous quest. Strictly observing the warlock's
instructions, after asking his way to the king of elfland's castle of
every servant he met, he, in accordance with these instructions, when he
had received the desired information, slew the servant. The last fairy
functionary he met was the hen-wife, who told him to go on a little

the bottom to the top, then go round it _widershins_ (contrary to the
sun) and every time he made the circuit, say--"Open door, open door, and
let me come in," and on the third repetition of this incantation they
would open, and he might then go in. Having received this information,
he fulfilled his instructions, and slew the hen-wife. Then proceeding as
directed, he soon reached the green hill, and made the circuit of it
three times, repeating the words before mentioned. On the third
repetition of the words the door opened, and he went in, the door
closing behind him. "He proceeded through a long passage, where the air
was soft and agreeably warm, like a May evening, as is all the air in
elfland. The light was a sort of twilight or gloaming; but there were
neither windows nor candles, and he knew not whence it came if it was
not from the walls and roof, wh
