And, to the familiar thump, thump of the electrical discharge, the Atom Smasher took up its backward journey once more. * * * * * A long time passed. With her head resting against Jim's breast, Lucille rested. Jim bent over her, trying to discover whether she was asleep or not. Her eyes were closed, her breathing so soft that she hardly seemed alive. An infinite pity for the girl filled Jim's heart, and, mingled with it, the intense determination to overcome the madman who had subjected her to these perils. He glanced across at Parrish, fingering his screws. Old Parrish looked up and nodded. There was a new determination in the old man's face that made him a different person from the crazed old man whom Jim had encountered at the Vanishing Place. "We can beat him, Parrish!" Jim called, and Parrish looked back and nodded again. "We're nearly back to the top of the column," he answered. Not long afterward Parrish looked up once more. "Stand by, Jim!" he called. "And be ready. Tode will be aware of our approach by means of the sensitive instruments he keeps in his laboratory. But don't harm him. We want him aboard, and we want him badly. He won't be able to play any more tricks with us. I've learned too much about the Atom Smasher." He pressed a lever, and the greyness dissolved into its component parts of light and darkness. A jar. Thump, thump! The violet light! Lucille looked up, raised herself, uttered a low cry and caught at Jim's arm, trembling. They had run their course truly. The Atom Smasher was vibrating outside the entrance to Tode's cave. And that was Tode, standing there, watching them, that devilish grin of his accentuated to the utmost. A blurred figure that appeared and vanished, and a surrounding crowd of Drilgoes--how many it was impossible to guess, for they looked like a crowd of apes in motion. Suddenly Tode disappeared, and a moment later Lucille uttered a terrified cry as his voice spoke in her ear: "I thought you'd be back. I knew you'd got away from Atlantis when my recorder showed the waves of electrical energy proceeding from the city. You were clever, Dent, but you see, you had to come back to me to get my help." "Don't be afraid, dear," said Jim, trying to soothe the girl. "That's a wireless receiving apparatus." He pointed to a sort of cabinet enclosed among the rotating wheels, and then it was evident that Tode's voice was proceeding from it. * * * * * Tode's figure appeared again, dancing through a haze of lines and patches. He was holding something in his hand which Jim made out to be the mouthpiece of a microphone. The voice inside the Atom Smasher spoke again: "Turn all the micrometer screws until the needles register zero, Parrish. Then turn Dial D to point 3, Dial C to 5, Dial B to 1, and Dial A to 2. I'll repeat.... Now press the starting lever, Parrish, and you'll find yourself on firm ground again."
