So they went into England, and went as far as Hereford; and they betook themselves to making shoes. He began by buying the best cordwain that could be had in the town, and associated himself with the best goldsmith in the town, and caused him to make clasps for the shoes, and to gild the clasps; and he marked how it was done until he learned the method. When they could be had from him, not a shoe nor hose was bought of any of the cordwainers in the town. When the cordwainers perceived that their gains were failing they came together and took counsel, and agreed that they would slay them. And he had warning thereof, and it was told him how the cordwainers had agreed together to slay him.

"Lord," said Kieva, "wherefore should this be borne from these boors?" "Nay," said he, "we will go back unto Dyved." So towards Dyved they set forth.

Now Manawyddan, when he set out to return to Dyved, took with him a burden of wheat. And he proceeded towards Narberth, and there he dwelt. Never was he better pleased than when he saw Narberth again, and the lands where he had been wont to hunt with Pryderi and with Rhiannon. And he accustomed himself to fish, and to hunt the deer in their covert. He began to prepare some ground, and he sowed a croft, and a second, and a third. And no wheat in the world ever sprung up better. The three crofts prospered with perfect growth, and no man ever saw fairer wheat.

Thus passed the seasons of the year until the harvest came. And he went to look at one of his crofts, and, behold, it was ripe. "I will reap this to-morrow," said he. On the morrow, when he came there, he found nothing but the bare straw. Every one of the ears of the wheat was cut off from the stalk, and all the ears carried entirely away. And at this he marvelled greatly.

Then he went to look at another croft, and, behold, that also was ripe. "Verily," said he, "this will I reap to-morrow." And on the morrow he came with the intent to reap it; and when he came there, he found nothing but the bare straw.

"O gracious Heaven!" he exclaimed. "I know that whosoever has begun my ruin is completing it, and has also destroyed the country with me."

Then he went to look at the third croft; and when he came there, finer wheat had there never been seen, and this also was ripe. "Evil betide me," said he, "if I watch not here to-night. Whoever carried off the other corn will come in like manner to take this, and I will know who it is." And he told Kieva all that had befallen. "Verily," said she, "what thinkest thou to do?" "I will watch the croft to-night," said he. And he went to watch the croft.

At midnight he heard something stirring among the wheat; and he looked, and behold, the mightiest host of mice in the world, which could neither be numbered nor measured. He knew not what it was until the mice had made their way into the croft, and each of them, climbing up the straw and bending it down with its weight, had cut off one of the ears of wheat and had carried it away, leaving there the stalk; and he saw not a single straw there that had not a mouse to it. And they all took their way, carrying the ears with them.

In wrath and anger did he rush upon the mice, but he could no more come up with them than if they had been gnats or birds of the air, except one only, which, though it was but sluggish, went so fast that a man on foot could scarce overtake it. After this one he went, and he caught it and put it in his glove, and tied up the opening of the glove with a string, and kept it with him, and returned to the palace. Then he came to the hall where Kieva was, and he lighted a fire, and hung the glove by the string upon a peg. "What hast thou there, lord?" said Kieva. "A thief," said he, "that I found robbing me." "What kind of a thief may it be, lord, that thou couldst put into thy glove?" said she. Then he told her how the mice came to the last of the fields in his sight. "And one of them was less nimble than the rest, and is now in my glove; to-morrow I will hang it." "My lord," said she, "this is marvellous; but yet it would be unseemly for a man of dignity like thee to be hanging such a reptile as this." "Woe betide me," said he, "if I would not hang them all, could I catch them, and such as I have I will hang." "Verily, lord," said she, "there is no reason that I should succor this reptile, except to prevent discredit unto thee. Do therefore, lord, as thou wilt."

Then he went to the Mound of Narberth, taking the mouse with him. He set up two forks on the highest part of the mound, and while he was doing this he saw a scholar coming towards him, in old and tattered garments. It was seven years since he had seen in that place either man or beast, except those four persons who had remained together until two of them were lost.
