At last the Wee Folk come in a great multitude to beg the release of Iubdan. On the king’s refusal they visit the country with various plagues, snipping off the ears of corn, letting the calves suck all the cows dry, defiling the wells, and so forth; but Fergus is obdurate. In their quality as earth-gods, _dei terreni_, they promise to make the plains before the palace of Fergus stand thick with corn every year without ploughing or sowing, but all is vain. At last, however, Fergus agrees to ransom Iubdan against the best of his fairy treasures, so Iubdan recounts them—the cauldron that can never be emptied, the harp that plays of itself; and finally he mentions a pair of water-shoes, wearing which a man can go over or under water as freely as on dry land. Fergus accepts the shoes, and Iubdan is released. *The Blemish of Fergus* But it is hard for a mortal to get the better of Fairyland—a touch of hidden malice lurks in magical gifts, and so it proved now. Fergus was never tired of exploring the depths of the lakes and rivers of Ireland; but one day, in Loch Rury, he met with a hideous monster, the _Muirdris_, or river-horse, which inhabited that lake, and from which he barely saved himself by flying to the shore. With the terror of this encounter his face was twisted awry; but since a blemished man could not hold rule in Ireland, his queen and nobles took pains, on some pretext, to banish all mirrors from the palace, and kept the knowledge of his condition from him. One day, however, he smote a bondmaid with a switch, for some negligence, and the maid, indignant, cried out: “It were better for thee, Fergus, to avenge thyself on the river-horse that hath twisted thy face than to do brave deeds on women!” Fergus bade fetch him a mirror, and looked in it. “It is true,” he said; “the river-horse of Loch Rury has done this thing.” *Death of Fergus* The conclusion may be given in the words of Sir Samuel Ferguson’s fine poem on this theme. Fergus donned the magic shoes, took sword in hand, and went to Loch Rury: “For a day and night Beneath the waves he rested out of sight, But all the Ultonians on the bank who stood Saw the loch boil and redden with his blood. When next at sunrise skies grew also red He rose—and in his hand the _Muirdris_’ head. Gone was the blemish! On his goodly face Each trait symmetric had resumed its place: And they who saw him marked in all his mien A king’s composure, ample and serene. He smiled; he cast his trophy to the bank, Said, ’I, survivor, Ulstermen!’ and sank."
