Just like an army of warrior ants it seemed to flow onward, in perfect order. And in the midst of it a faint violet light began to be visible.

Parrish seized Jim's arm, shaking with terror. "You know what that is, Dent?" he whimpered.

"It's Tode's Drilgoes, moving for a night attack upon Atlantis," answered Jim. "And that thing in the middle is the Atom Smasher."


t seemed hours before the last of the serried ranks of Drilgoes had passed. By the light of a lurid flash from the volcano Jim could see the column winding toward the causeway. Then all was shrouded in impenetrable darkness, save for the snow-soft city upon the island.

"What are we going to do?" chattered old Parrish. "I wish I was back in Tode's cave. He gave me food and let me help with his work sometimes. I'll die here. We'll never get away. We'll never get anywhere."

"We're safer here than anywhere else," answered Jim. "We'll have to stay till morning, or—God, look at that!"

Out of the ramparts of the city the round, blue-white disc of the Eye had suddenly disclosed itself. And simultaneously a violet flare shot up above the moving hosts of the Drilgoes in the middle of the causeway.

Out of the center of the Eye that blinding searchlight streamed. And the pillar of violet fire rose up to counter it, clove it in two, as a man cuts off the tentacle of a cuttlefish, and left it groping helplessly above the heads of the Drilgoes.
