He lost position, and knew that the two-minute interval was drawing to a close. He soared and fired again. The Eye still glowed.

Then of a sudden a blinding ray shot forth from it, so dazzling that it seemed to sear Jim's eyeballs. The interval was ended.

It shot beneath him, but no more than a few feet, and turning his eyes shoreward, Jim saw it sweep along the causeway and tear a black path through the forest. Frantically he soared, and circled around the temple.

The ray went out. Two minutes more. And now the temporary panic had passed; Jim's nerves grew steady as a rock. He eased the controls and floated in toward the glowing orb. Sea-mews, screaming, dashed themselves against it and fell, wounded and broken, into the breaking seas below. They fluttered past Jim's face, one impacted against his chest with a thud that rocked him where he hovered.

But Jim knew that he could not fail. At a distance of fifty feet he drew a bead upon the centre of the Eye and pressed the trigger.

And instantly the light went out....

It was the death-keening of proud Atlantis, Queen of the Atlantic for fifty thousand years. She was dying in darkness.
