"Then," added William, growing bolder in his proposals, "since thou consentest to serve me, thou must engage to fortify the castle of Dover, to dig there a well of fresh water, and when the time comes, to deliver up the place to my people. Moreover, to make the bond between us the stronger, thou must give thy sister Thyra in marriage to one of my barons; and thou must take to wife my daughter Adeliza. On thy departure, thou must leave me, as guarantee for thy promise, one of the two hostages thou hast come to reclaim, and I will restore him to thee in England when I come there as king." "I acquiesce in your demands," said Harold, eager to get rid of a subject which every moment became more embarrassing, and, without pursuing the conversation further, the duke and the earl rode on side by side towards Bayeux. But it soon became apparent that William the Norman was by no means satisfied with the promise he had wrung from his Saxon guest. No sooner had the duke reached Bayeux than he prepared to exact a more solemn and ceremonious pledge; and, having caused such sacred relics as bones of saints to be brought from the churches, placed in a vessel in the council hall of the castle, and covered with a rich cloth of gold, so as to have the appearance of a table, he convoked his barons and prelates on a certain day, and intimated to Harold that his presence would be required. At the hour appointed, baron and bishop crowded to the council hall; and William, with a sword in his hand and the coronal of Normandy on his brow, took his seat on the throne, caused two small reliquaries to be placed on the cloth of gold, and intimated, by a gesture, his desire that Harold should approach. "Harold," said the Duke, "I require thee, before this noble assembly, to confirm, by oath, the promises thou hast made to me--namely, to aid me to obtain the kingdom of England after the death of King Edward, to marry my daughter, and to send thy sister, that I may give her to one of my lords." "I swear," said Harold, extending his hand over the two reliquaries, "to execute my promise as far as lies in my power, if I live, and if God aid me." "God aid him!" repeated the barons and bishops who stood around. The ceremony being thus complete, William made a sign; the cloth of gold was raised; and before Harold's eyes lay bones and entire skeletons of saints, upon which he had, without suspecting their presence, so solemnly sworn. With a shudder and a change of countenance, which did not escape notice, he turned away from the sight. But the oath which he had sworn appeared to the Normans far too sacred ever to be broken; and he was allowed to depart for England with his nephew, the son of Sweyn. William accompanied them to the seaside, made them valuable presents, and repaired to Rouen, rejoicing in the thought, that the man most likely to have baffled his aspirations after the crown of England, was bound, by the most solemn oath, to aid him to the utmost.
