They journeyed together to many places, both at home and across the seas, and the damsel was wearied of him, and sought by every means to be rid of him, but he would not be shaken off. At last these two wandered back to Cornwall, and one day Merlin showed Vivien a rock under which he said great marvels were hidden. Then Vivien put forth all her powers, and told Merlin how she longed to see the wonders beneath the stone, and, in spite of all his wisdom, Merlin listened to her and crept under the rock to bring forth the strange things that lay there. And when he was under the stone she used the magic he had taught her, and the rock rolled over him, and buried him alive, as he had told King Arthur. But the damsel departed with joy, and thought no more of him, now that she knew all the magic he could teach her. [Illustration: MERLIN and VIVIEN] PART II. THE QUEST OF THE HOLY GRAAL. I. How the King went on Pilgrimage and his Squire was slain in a Dream. Now the King was minded to go on a pilgrimage, and he agreed with the Queen that he would set forth to seek the holy chapel at St. Augustine, which is in the White Forest, and may only be found by adventure. Much he wished to undertake the quest alone, but this the Queen would not suffer, and to do her pleasure he consented that a youth, tall and strong of limb, should ride with him as his squire. Chaus was the youth’s name, and he was son to Gwain li Aoutres. “Lie within to-night,” commanded the King, “and take heed that my horse be saddled at break of day, and my arms ready.” “At your pleasure, Sir,” answered the youth, whose heart rejoiced because he was going alone with the King. As night came on, all the Knights quitted the hall, but Chaus the squire stayed where he was, and would not take off his clothes or his shoes, lest sleep should fall on him and he might not be ready when the King called him. So he sat himself down by the great fire, but in spite of his will sleep fell heavily on him, and he dreamed a strange dream.
