The four proceeded along the hall and over the tongue of flooring. This time the force that had previously controlled their movements was not in action. At the farther end of the bridge they saw the group of dignitaries gathered about the Atom Smasher, examining it curiously. Over their heads the hooked arms of the hideous gods were raised. The Eye was darkened, as if with a curtain, and through the glass roof, high overhead, the sunlight streamed down upon the empty amphitheatre. * * * * * In spite of their smiles, the dignitaries of Atlantis were very much on the alert, as their tense attitudes denoted. Two more guards had appeared, and Jim saw that they were uncovering some apparatus at the base of the Eye. They were swinging a camera-like object toward him, its lens focused upon the Atom Smasher. It was not difficult to understand what was in the minds of the Atlanteans. The dignitaries were uneasy and mistrustful, and at the first suspicion of treachery they meant to loose the blue-white Ray contained in the apparatus, and blow the Atom Smasher and the group about it to destruction. Jim intercepted a sign from Parrish, indicating that he was to make pretense of assisting him. He bent over the machine, Lucille beside him. Parrish was busily examining the wheels and levers. He was adjusting the thumbscrews, moving the needles along the dials. One of the Atlanteans spoke, and Cain translated into "Drilgo" for Parrish's benefit. Parrish answered. Then, without raising his head, the old man said quietly, "I've located the starting lever, Dent. You and Lucille get inside quickly and pretend you're doing something to the machinery." They stepped over the bow of the boat and stood beside Parrish, who continued examining the wheels. "We mustn't forget Cain," whispered the girl to her father. "Oh, I hope he understands!" But there was no direct evidence that Cain did understand, and Parrish dared not warn him in "Drilgo," for fear one of the Atlanteans might understand the language. Cain was standing close beside the boat. But he was not in the boat. Again one of the Atlanteans shot a question at Parrish. Parrish beckoned to Cain, and awaited the translation. He answered. Each moment was growing tenser. It was impossible that the Atlanteans could fail to understand what was being planned. The only saving chance was that they did not realize the possibilities of escape that the vessel offered. A full minute went by. * * * * * Suddenly Parrish raised his head. "I've got it fixed, I think, Dent," he said. "I'm going to count. When I reach 'three,' seize Cain and pull him aboard."
