"My horse is a beast of mettle," he observed complacently when the groom had returned to his work.

"Ay, and I would that his master, the Evil One, had the grooming of him," was the retort.

"Why, how now, sirrah! Dost thou slander the horse which is a gift from Mother Church to the king's work? Thou art a knave, and no doubt art but unfit for thy task this morn through over-late carousing last night."

"Thou mayest call it carousing, if thou wilt," said the groom, sulkily. "I did come from Gainsborough yesterday. And in the dark, as I did come, I saw a flaming fire in the Isle of Axholme."

"And what meanest thou to tell me of that?" demanded Walter Skinner, sternly. "Thou wert no doubt so drunk that a will-o'-the-wisp in that boggy place did seem to thee even as a flaming fire. Why dost thou not stand to my horse and get down with him? He hath already backed and turned a matter of some miles."

The groom stopped and looked at him indignantly. "I may be but a groom," he said, "but the Isle of Axholme I know from a child, every bog in it. And I did go to the fire, which was a bit out of my way, but, being my only pleasure on the journey, I did take it. And there on the rushes lay a young lord, and his serving-man did feed the fire with reeds."

"Thou didst see that?" cried Walter Skinner, in great excitement. "Make haste with the beast, sirrah. Here is a coin for thee, good groom. I do now see thou wert never drunken in thy life. Make haste with the horse."

The groom stared at him foolishly. "Why, who could make haste with such a beast?" he said at length.

"Then stay not to finish thy work," cried Walter Skinner, impatiently. "Bring saddle and bridle. I must away instantly. But do thou first describe to me the place where thou didst see the fire."

"The place," said the groom, deliberately, while he examined the coin Walter Skinner had given him. "Thou dost go till thou comest to it. A turn here and a turn there mayhap thou must make, and thou wilt find it a little solid place with three scrub trees upon it. It is a matter of a short distance from the south end of the Isle, and thou wilt not fail to know it when thou seest it."
