For the third time, the work proceeded. Yet when the sun rose next morning, there was not even a trace of either material or labor.

What was the matter? Had some dragon swallowed everything up?

Vortigern again summoned his twelve wise men, to meet in council, and to inquire concerning the cause of the marvel and to decide what was to be done.

After long deliberation, while all the workmen and people outside waited for their verdict, the wise men agreed upon a remedy.

Now in ancient times, it was a custom, all over the world, notably in China and Japan and among our ancestors, that when a new castle or bridge was to be built, they sacrificed a human being. This was done either by walling up the victim while alive, or by mixing his or her blood with the cement used in the walls. Often it was a virgin or a little child thus chosen by lot and made to die, the one for the many.

The idea was not only to ward off the anger of the spirits of the air, or to appease the dragons under ground, but also to make the workmen do their best work faithfully, so that the foundation should be sure and the edifice withstand the storm, the wind, and the earthquake shocks.

So, nobody was surprised, or raised his eyebrows, or shook his head, or pursed up his lips, when the king announced that what the wise men declared, must be done and that quickly. Nevertheless, many a mother hugged her darling more closely to her bosom, and fathers feared for their sons or daughters, lest one of these, their own, should be chosen as the victim to be slain.

King Vortigern had the long horn blown for perfect silence, and then he spoke:

"A child must be found who was born without a father. He must be brought here and be solemnly put to death. Then his blood will be sprinkled on the ground and the citadel will be built securely."

Within an hour, swift runners were seen bounding over the Cymric hills. They were dispatched in search of a boy without a father, and a large reward was promised to the young man who found what was wanted. So into every part of the Cymric land, the searchers went.
