Now through the last trees he saw full daylight. Less than half a mile separated him from the border of the forest, and, eager to discover what lay beyond, he broke into a run. He heard the surf louder. It was a peculiar hissing sound that could proceed only from water, yet was unlike the sea. Almost immediately he came within sight of an enormous horizon of dancing waves, which he knew must be the Sinking Sea. He fell back into a quick walk, continuing to stare hard. The wind that met him was hot, fresh and sweetWhen 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.
