For some time nothing more was seen or heard of the Worm, till one day it had outgrown the size of the well, and came forth full-grown. So it came forth from the well and betook itself to the Wear. And all day long it would lie coiled round a rock in the middle of the stream, while at night it came forth from the river and harried the country side. It sucked the cows' milk, devoured the lambs, worried the cattle, and frightened all the women and girls of the district, and then it would retire for the rest of the night to the hill, still called the Worm Hill, on the north side of the Wear, about a mile and a half from Lambton Hall.
This terrible visitation brought young Lambton, of Lambton Hall, to his senses. He took upon himself the vows of the Cross, and departed for the Holy Land, in the hope that the scourge he had brought upon his district would disappear. But the grisly Worm took no heed, except that it crossed the river and came right up to Lambton Hall itself where the old lord lived on all alone, his only son having gone to the Holy Land. What to do? The Worm was coming closer and closer to the Hall; women were shrieking, men were gathering weapons, dogs were barking and horses neighing with terror. At last the steward called out to the dairy maids, "Bring all your milk hither," and when they did so, and had brought all the milk that the nine kye of the byre had yielded, he poured it all into the long stone trough in front of the Hall.
The Worm drew nearer and nearer, till at last it came up to the trough. But when it sniffed the milk, it turned aside to the trough and swallowed all the milk up, and then slowly turned round and crossed the river Wear, and coiled its bulk three times round the Worm Hill for the night.
Henceforth the Worm would cross the river every day, and woe betide the Hall if the trough contained the milk of less than nine kye. The Worm would hiss, and would rave, and lash its tail round the trees of the park, and in its fury it would uproot the stoutest oaks and the loftiest firs. So it went on for seven years. Many tried to destroy the Worm, but all had failed, and many a knight had lost his life in fighting with the monster, which slowly crushed the life out of all that came near it.
At last the Childe of Lambton came home to his father's Hall, after seven long years spent in meditation and repentance on holy soil. Sad and desolate he found his folk: the lands untilled, the farms deserted, half the trees of the park uprooted, for none would stay to tend the nine kye that the monster needed for his food each day.
The Childe sought his father, and begged his forgiveness for the curse he had brought on the Hall.
"Thy sin is pardoned," said his father; "but go thou to the Wise Woman of Brugeford, and find if aught can free us from this monster."
To the Wise Woman went the Childe, and asked her advice.
"'T is thy fault, O Childe, for which we suffer," she said; "be it thine to release us."
"I would give my life," said the Childe.
