A tradition is current in Mathavarn, in the parish of Llanwrin, and the Cantref of Cyfeillioc, concerning a certain wood called Ffridd yr Ywen, (the Forest of the Yew,) that it is so called on account of a magical yew-tree which grows exactly in the middle of the forest. Under that tree there is a fairy circle called The Dancing Place of the Goblin. There are several fairy circles in the Forest of the Yew, but the one under the yew-tree in the middle has this legend connected with it: Many years ago, two farm-servants, whose names were Twm and Iago, went out one day to work in the Forest of the Yew. Early in the afternoon the country became covered with so dense a mist that the youths thought the sun was setting, and they prepared to go home; but when they came to the yew-tree in the middle of the forest, suddenly they found all light around them. They now thought it too early to go home, and concluded to lie down under the yew-tree and have a nap. By-and-by Twm awoke, to find his companion gone. He was much surprised at this, but concluded Iago had gone to the village on an errand of which they had been speaking before they fell asleep. So Twm went home, and to all inquiries concerning Iago, he answered, 'Gone to the cobbler's in the village.' But Iago was still absent next morning, and now Twm was cross-questioned severely as to what had become of his fellow-servant. Then he confessed that they had fallen asleep under the yew where the fairy circle was, and from that moment he had seen nothing more of Iago. They searched the whole forest over, and the whole country round, for many days, and finally Twm went to a gwr cyfarwydd (or conjuror), a common trade in those days, says the legend. The conjuror gave him this advice: 'Go to the same place where you and the lad slept. Go there exactly a year after the boy was lost. Let it be on the same day of the year and at the same time of the day; but take care that you do not step inside the fairy ring. Stand on the border of the green circle you saw there, and the boy will come out with many of the goblins to dance. When you see him so near to you that you may take hold of him, snatch him out of the ring as quickly as you can.' These instructions were obeyed. Iago appeared, dancing in the ring with the Tylwyth Teg, and was promptly plucked forth. 'Duw! Duw!' cried Tom, 'how wan and pale you look! And don't you feel hungry too?' 'No,' said the boy, 'and if I did, have I not here in my wallet the remains of my dinner that I had before I fell asleep?' But when he looked in his wallet, the food was not there. 'Well, it must be time to go home,' he said, with a sigh; for he did not know that a year had passed by. His look was like a skeleton, and as soon as he had tasted food, he mouldered away. VII.
