Around another island there was a demon horse-race going on; the riders were just riding in over the sea, and then the race began; the voyagers could only dimly perceive the forms of the horses, but could hear the cries of their riders, the strokes of the whips, and the words of the spectators, "See the gray horse!" "Watch the chestnut horse!" and the voyagers were so alarmed that they rowed away. The next island was covered with trees laden with golden apples, but these were being rapidly eaten by small, scarlet animals which they found, on coming nearer, to be all made of fire and thus brightened in hue. Then the animals vanished, and Maelduin with his men landed, and though the ground was still hot from the fiery creatures, they brought away a boat load of the apples. Another island was divided into two parts by a brass wall across the middle. There were two flocks of sheep, and those on one side of the wall were white, while the others were black. A large man was dividing and arranging the sheep, and threw them easily over the wall. When he threw a white sheep among the black ones it became black, and when he threw a black sheep among the white ones, it became white instantly. The voyagers thought of landing, but when Maelduin saw this, he said, "Let us throw something on shore to see if it will change color. If it does, we will avoid the island." So they took a black branch and threw it toward the white sheep. When it fell, it grew white; and the same with a white branch on the black side. "It is lucky for us," said Maelduin, "that we did not land on this island." They came next to an island where there was but one man visible, very aged, and with long, white hair. Above him were trees, covered with great numbers of birds. The old man told them that he like them had come in a curragh, or coracle, and had placed many green sods beneath his feet, to steady the boat. Reaching this spot, the green sods had joined together and formed an island which at first gave him hardly room to stand; but every year one foot was added to its size, and one tree grew up. He had lived there for centuries, and those birds were the souls of his children and descendants, each of whom was sent there after death, and they were all fed from heaven each day. On the next island there was a great roaring as of bellows and a sound of smiths' hammers, as if striking all together on an anvil, every sound seeming to come from the strokes of a dozen men. "Are they near?" asked one big voice. "Silence!" said another; and they were evidently watching for the boat. When it rowed away, one of the smiths flung after them a vast mass of red-hot iron, which he had grasped with the tongs from the furnace. It fell just short, but made the whole sea to hiss and boil around them as they rowed away.
