As they approached this they heard from afar as it were the clanging of a tremendous smithy, and heard men talking of themselves. “Little boys they seem,” said one, “in a little trough yonder.” They rowed hastily away, but did not turn their boat, so as not to seem to be flying; but after a while a giant smith came out of the forge holding in his tongs a huge mass of glowing iron, which he cast after them, and all the sea boiled round it, as it fell astern of their boat. *The Sea of Clear Glass* After that they voyaged until they entered a sea that resembled green glass. Such was its purity that the gravel and the sand of the sea were clearly visible through it; and they saw no monsters or beasts therein among the crags, but only the pure gravel and the green sand. For a long space of the day they were voyaging in that sea, and great was its splendour and its beauty.(199) *The Undersea Island* They next found themselves in a sea, thin like mist, that seemed as if it would not support their boat. In the depths they saw roofed fortresses, and a fair land around them. A monstrous beast lodged in a tree there, with droves of cattle about it, and beneath it an armed warrior. In spite of the warrior, the beast ever and anon stretched down a long neck and seized one of the cattle and devoured it. Much dreading lest they should sink through that mist-like sea, they sailed over it and away. *The Island of the Prophecy* When they arrived here they found the water rising in high cliffs round the island, and, looking down, saw on it a crowd of people, who screamed at them, “It is they, it is they,” till they were out of breath. Then came a woman and pelted them from below with large nuts, which they gathered and took with them. As they went they heard the folk crying to each other: “Where are they now?” “They are gone away.” “They are not.” “It is likely,” says the tale, “that there was some one concerning whom the islanders had a prophecy that he would ruin their country and expel them from their land.” *The Island of the Spouting Water* Here a great stream spouted out of one side of the island and arched over it like a rainbow, falling on the strand at the further side. And when they thrust their spears into the stream above them they brought out salmon from it as much as they would, and the island was filled with the stench of those they could not carry away. *The Island of the Silvern Column*
