In the legend of Iolo ap Hugh, than which no story is more widely known in Wales, the fairy origin of that famous tune 'Ffarwel Ned Pugh' is shown. It is a legend which suggests the Enchanted Flute fancy in another form, the instrument here being a fiddle, and the victim and player one under fairy control. In its introduction of bread and cheese and candles it smacks heartily of the soil. In North Wales there is a famous cave which is said to reach from its entrance on the hillside 'under the Morda, the Ceiriog, and a thousand other streams, under many a league of mountain, marsh and moor, under the almost unfathomable wells that, though now choked up, once supplied Sycharth, the fortress of Glyndwrdwy, all the way to Chirk Castle.' Tradition said that whoever went within five paces of its mouth would be drawn into it and lost. That the peasants dwelling near it had a thorough respect for this tradition, was proved by the fact that all around the dangerous hole 'the grass grew as thick and as rank as in the wilds of America or some unapproached ledge of the Alps.' Both men and animals feared the spot: 'A fox, with a pack of hounds in full cry at his tail,' once turned short round on approaching it, 'with his hair all bristled and fretted like frostwork with terror,' and ran into the middle of the pack, 'as if anything earthly--even an earthly death--was a relief to his supernatural perturbations.' And the dogs in pursuit of this fox all declined to seize him, on account of the phosphoric smell and gleam of his coat. Moreover, 'Elias ap Evan, who happened one fair night to stagger just upon the rim of the forbidden space,' was so frightened at what he saw and heard that he arrived at home perfectly sober, 'the only interval of sobriety, morning, noon, or night, Elias had been afflicted with for upwards of twenty years.' Nor ever after that experience--concerning which he was wont to shake his head solemnly, as if he might tell wondrous tales an' he dared--could Elias get tipsy, drink he never so faithfully to that end. As he himself expressed it, 'His shadow walked steadily before him, that at one time wheeled around him like a pointer over bog and stone.' One misty Hallow E'en, Iolo ap Hugh, the fiddler, determined to solve the mysteries of the Ogof, or Cave, provided himself with 'an immense quantity of bread and cheese and seven pounds of candles,' and ventured in. He never returned; but long, long afterwards, at the twilight of another Hallow E'en, an old shepherd was passing that--as he called it--'Land-Maelstrom of Diaboly,' when he heard a faint burst of melody dancing up and down the rocks above the cave. As he listened, the music gradually 'moulded itself in something like a tune, though it was a tune the shepherd had never heard before.' And it sounded as if it were being played by some jolting fiend, so rugged was its rhythm, so repeated its discordant groans. Now there appeared
