When Maildun and his people saw this, they were seized with great terror; for they feared they should not be able to cross the sea over the monster, on account of the extreme mist-like thinness of the water; but after much difficulty and danger they got across it safely. CHAPTER XXIV. AN ISLAND GUARDED BY A WALL OF WATER. When they came to the next island, they observed with astonishment that the sea rose up over it on every side, steep and high, standing, as it were, like a wall all round it. When the people of the island saw the voyagers, they rushed hither and thither, shouting, "There they are, surely! There they come again for another spoil!" Then Maildun's people saw great numbers of men and women, all shouting and driving vast herds of horses, cows, and sheep. A woman began to pelt the crew from below with large nuts; she flung them so that they alighted on the waves round the boat, where they remained floating; and the crew gathered great quantities of them and kept them for eating. When they turned to go away, the shouting ceased: and they heard one man calling aloud, "Where are they now?" and another answering him, "They are gone away!" From what Maildun saw and heard at this island, it is likely that it had been foretold to the people that their country should some day be spoiled by certain marauders; and that they thought Maildun and his men were the enemies they expected. CHAPTER XXV. A WATER-ARCH IN THE AIR. On the next island they saw a very wonderful thing, namely, a great stream of water which, gushing up out of the strand, rose into the air in the form of a rainbow, till it crossed the whole island and came down on the strand at the other side. They walked under it without getting wet; and they hooked down from it many large salmon. Great quantities of salmon of a very great size fell also out of the water over their heads down on the ground; so that the whole island smelled of fish, and it became troublesome to gather them on account of their abundance. From the evening of Sunday till the evening of Monday, the stream never ceased to flow, and never changed its place, but remained spanning the island like a solid arch of water. Then the voyagers gathered the largest of the salmon, till they had as much as the curragh would hold; after which they sailed out into the great sea. CHAPTER XXVI. THE SILVER PILLAR OF THE SEA. The next thing they found after this was an immense silver pillar standing in the sea. It had eight sides, each of which was the width of an oar-stroke of the curragh, so that its whole circumference was eight oar-strokes. It rose out of the sea without any land or earth about it, nothing but the boundless ocean; and they could not see its base deep down in the water, neither were they able to see the top on account of its vast height.
