When he arrived at the final fringe of forest, which joined the wide sands of the shore without any change of level, he leaned with his back to a great tree and gazed his fill, motionless, at what lay in front of him. The sands continued east and west in a straight line, broken only here and there by a few creeks. They were of a brilliant orange colour, but there were patches of violet. The forest appeared to stand sentinel over the shore for its entire length. Everything else was sea and sky—he had never seen so much water. The semicircle of the skyline was so vast that he might have imagined himself on a flat world, with a range of vision determined only by the power of his eye. The sea was unlike any sea on Earth. It resembled an immense liquid opal. On a body colour of rich, magnificent emerald-green, flashes of red, yellow, and blue were everywhere shooting up and vanishing. The wave motion was extraordinary. Pinnacles of water were slowly formed until they attained a height of perhaps ten or twenty feet, when they would suddenly sink downward and outward, creating in their descent a series of concentric rings for long distances around them. Quickly moving currents, like rivers in the sea, could be seen, racing away from land; they were of a darker green and bore no pinnacles. Where the sea met the shore, the waves rushed over the sands far in, with almost sinister rapidity—accompanied by a weird, hissing, spitting sound, which was what Maskull had heard. The green tongues rolled in without foam. About twenty miles distant, as he judged, directly opposite him, a long, low island stood up from the sea, black and not distinguished in outline. It was Swaylone’s Island. Maskull was less interested in that than in the blue sunset that glowed behind its back. Alppain had set, but the whole northern sky was plunged into the minor key by its afterlight. Branchspell in the zenith was white and overpowering, the day was cloudless and terrifically hot; but where the blue sun had sunk, a sombre shadow seemed to overhang the world. Maskull had a feeling of disintegration—just as if two chemically distinct forces were simultaneously acting upon the cells of his body. Since the afterglow of Alppain affected him like this, he thought it more than likely that he would never be able to face that sun itself, and go on living. Still, some modification might happen to him that would make it possible. The sea tempted him. He made up his mind to bathe, and at once walked toward the shore. The instant he stepped outside the shadow line of the forest trees, the blinding rays of the sun beat down on him so savagely that for a few minutes he felt sick and his head swam. He trod quickly across the sands. The orange-coloured parts were nearly hot enough to roast food, he judged, but the violet parts were like fire itself. He stepped on a patch in ignorance, and immediately jumped high into the air with a startled yell.
