The finger of light played along the tilted side of a wrecked tramp steamer. There was a crumpled gash in the bow. From this ragged hole suddenly appeared a great, serpentine form....
The Professor clutched at his camera, pointed it, and clenched his hands in a frenzy of disappointment. The serpent shape had disappeared back into the hull. A little later and we had drifted slowly past the wreck.
"Damn it!" the Professor snatched away his mouthpiece to exclaim: "If we could only stop."
The bottom changed character shortly after we had passed the hulk. We began to creep over low, gently rounded mounds.
These were so regular in form that they were puzzling. About fifty feet across and ten in altitude, they looked artificial in their symmetry—like great saucers set on the ocean floor bottom side up. They took on a dirty black hue as our light struck them, and glowed with a faint phosphorescence as they stretched away into the darkness.
A twelve-foot monstrosity, all toad-like head and eyes, swam into the light beam and bumped blindly against the glass ball. For an instant it goggled crazily at us. The Professor took its picture. It blundered away. As it reached the darkness beyond the beam it, too, showed phosphorescent. A belt of blue-white spots like the portholes of a liner extended down its ugly sides.
Along the bottom, between the curious mounds, writhed a wormlike thing. But it was too huge to be described as truly wormlike—it was eighteen or twenty feet long and a foot thick. It was blood red, almost blunt ended and patently without eyes.
I took my gaze off it for an instant. When I looked again it had disappeared. I blinked at this seeming miracle and then discovered a foot or so of its tail protruding from under the edge of one of the mounds. It was threshing furiously about.
It was at this instant that I suddenly found increased difficulty, and glanced at Stanley.
