The laidly worm of Spindleston Heugh

But they ran away shrieking, and the Laidly Worm crawled and crept, and crept and crawled till it reached the Heugh or rock of the Spindlestone, round which it coiled itself, and lay there basking with its terrible snout in the air.

Soon the country round about had reason to know of the Laidly Worm of Spindleston Heugh. For hunger drove the monster out from its cave and it used to devour everything it could come across. So at last they went to a mighty warlock and asked him what they should do. Then he consulted his works and his familiar, and told them: "The Laidly Worm is really the Princess Margaret and it is hunger that drives her forth to do such deeds. Put aside for her seven kine, and each day as the sun goes down, carry every drop of milk they yield to the stone trough at the foot of the Heugh, and the Laidly Worm will trouble the country no longer. But if ye would that she be borrowed to her natural shape, and that she who bespelled her be rightly punished, send over the seas for her brother, Childe Wynd."

All was done as the warlock advised, the Laidly Worm lived on the milk of the seven kine, and the country was troubled no longer. But when Childe Wynd heard the news, he swore a mighty oath to rescue his sister and revenge her on her cruel stepmother. And three-and-thirty of his men took the oath with him. Then they set to work and built a long ship, and its keel they made of the rowan tree. And when all was ready, they out with their oars and pulled sheer for Bamborough Keep.

But as they got near the keep, the stepmother felt by her magic power that something was being wrought against her, so she summoned her familiar imps and said: "Childe Wynd is coming over the seas; he must never land. Raise storms, or bore the hull, but nohow must he touch shore." Then the imps went forth to meet Childe Wynd's ship, but when they got near, they found they had no power over the ship, for its keel was made of the rowan tree. So back they came to the queen witch, who knew not what to do.
