Henry Kuttner, Dark Dawn (1947)
“ So it swam down, down in the pearly light of dawn, with the sea and sky an enormous emptiness and the Albacore a small dark shape miles away, and Gresham’s body hidden within it, asleep, while his mind sank with the Swimmer through the fathomless seas.Down and down, into the great deeps under the atolls, where abysses lie deeper than Everest is high. The Swimmer could plumb them, for the Swimmer was not human. Intelligent, yes, but—different. Life under the waters would follow a different course from life in the air. And cities under the sea would be very different, too. ”
