But the spear never left the Drilgo's hand in Jim's direction. Like a great black ape, Cain leaped upon the fellow and bore him to the ground, his feet twined around his shoulders, his hands gripping his throat. Not until the Drilgo had been reduced to a heaving, half-strangled hulk did Cain leave him.

Then Cain, bending until his stomach almost touched the ground, came worming toward Jim, making signs of obeisance.

What had happened that Jim had won the Drilgo's faith? Why did Cain now look upon him, apparently, as his master? It was impossible to gauge the processes of the black man's mind, and at the moment Jim was in no mood to wonder. The stunning disaster that had overtaken him monopolized his thoughts.

Lucille and Parrish were once more in Tode's power. That was the dominating fact. The only gleam of comfort in the situation was that Tode had given him the clue to his movements.

Beyond a doubt Tode had taken his captives into Atlantis with him. It was impossible to disbelieve Tode's statement that he had been offered the supreme power in the city. Tode's egotism would have compelled him to blurt out that fact. Besides, Tode had certainly not gone back to earth.

Jim must force his way into Atlantis. He would find and rescue the two prisoners or die there.

He turned away from the groveling Cain and the chattering Drilgoes, who, inspired by Cain's example, now seemed animated by the same instinct to obey him, and went into the cave. But at the entrance he turned for a moment and looked back.


t was night. The valley was swathed in mists, the volcano opposite was spouting a shaft of lurid fire. On the water was a path of moonlight, where the clouds had been dispersed by the Atlanteans. Jim took in the scene, he raised one arm and shook his fist. Then, without a word, he passed inside.
