As he spoke he was jerking Lanier with him behind the looming earthen statue of the great worm god. Crouched there between the statue and the cave's wall they were hidden precariously from the view of those in the cavern. And now that cavern had become a scene of horror unthinkable as the centipede-machines pouring down into it blasted the frantically crawling worm monsters with their rays.
The worm monsters attempted no resistance, but sought only to escape into their downward tunnels, and in moments those not caught by the rays had vanished in the openings. But the centipede-machines, after racing swiftly around the cavity, were following them, were going down into those downward tunnels also, their rays blasting down ahead of each to make the tunnel large enough for them to follow.
In a moment all but one had vanished down into the openings, the remaining one having its front or head jammed in one of the openings from the failure of its operator to blast a large enough opening before him. As Lanier and Randall watched tensely they saw the machine's control room door open and a Martian descend. He inspected the tunnel opening in which his vehicle was jammed, then with a hand ray-tube began to disintegrate the earth around that opening to free his machine.
Randall clutched his companion's arm. "That machine!" he whispered. "If we could capture it, it would give us a chance to get back to the city—to Milton and the matter-transmitter!"
Lanier started, then nodded swiftly. "We'll chance it," he whispered. "For our twenty-four hours here must be almost up."
hey hesitated a moment, then crept forward from behind the great earthen statue. The Martian had his back to them, his attention on the freeing of his mechanism. Across the dim-lit cavern they crept softly, and were within a dozen feet of the Martian when some sound made him wheel quickly to confront them with the deadly tube. But even as he whirled the two had leaped.
The force of their leap sent them flying through that dozen feet of space to strike the Martian at the moment his tube levelled. One hissing call he uttered as they struck him, and then with all his strength Lanier had grasped the crocodilian body and bent it backward. Something in it snapped, and the Martian collapsed limply. The two looked wildly around.
Nothing showed that the Martian's call had been heard, and after a moment's glance that showed the head of the centipede machine already freed, they were clambering up into its control room, closing the door. Randall seized the knob with which he had seen the machines operated. As he pulled it toward him the machine moved across the tunnel opening and raced smoothly over the cavern's floor. As he turned the knob the machine turned swiftly in the same direction.
