The serpents!--those horrors from space that had come with the coming of the Dark Moon! They had disrupted the high-level traffic of the world; had seized great, liners; torn their way in; stripped them of every living thing, and let the empty shells crash back to earth. Chet had forgotten or he had failed to realize the height at which this new pilot was flying. Only speed could save them; the monsters, with their snouts that were great suction-cups, could wrench off a metal door--tear out the glass from a port! * * * * * He saw the luminous mass crush itself against a forward lookout and felt the jar of its body against their ship. Soft and vaporous, these cloud-like serpents seemed as they drifted through space; yet the impact, when they struck, proved that this new matter had mass. Chet saw the figure at the controls stagger back and cower in fear; the man's bullet-shaped head was covered by his upraised arms: there was some horror outside those windows that his eyes had no wish to see. Beside him the towering figure of Schwartzmann appeared; he had sprung into Chet's view, and he screamed orders at the fear-stricken pilot. "Fool! Swine!" Schwartzmann was shouting. "Do something! You said you could fly this ship!" In desperation he leaped forward and reached for the controls himself. Chet's blurred faculties snapped sharply to attention. That yellow glow against the port--the jarring of their ship--it meant instant destruction once that searching snout found some place where it could secure a hold. If the air-pressure within the ship were released; if even a crack were opened!-- "Here, you!" he shouted to the frantic Schwartzmann who was jerking frenziedly at the controls that no longer gave response. "Cut these ropes!--leave those instruments alone, you fool!" He was suddenly vibrant with hate as he realized what this man had done: he had struck him, Chet, down as he would have felled an animal for butchery; he had stolen their ship; and now he was losing it. Chet hardly thought of his own desperate plight in his rage at this threat to their ship, and at Schwartzmann's inability to help himself. "Cut these ropes!" he repeated. "Damn it all, turn me loose; I can fly us out!" He added his frank opinion of Schwartzmann and all his men. And Schwartzmann, though his dark face flushed angrily red for one instant, leaped to Chet's side and slashed at the cords with a knife. The room swam before Chet's dizzy eyes as he came to his feet. He half fell, half drew himself full length toward the valve that he alone knew. Then again he was on his feet, and he gripped at the ball-control with one hand while he opened a master throttle that cut in this new supply of explosive. * * * * *
