The room had been silent with the silence of empty space, save only for the scraping of a horrid body across the ship's outer shell. The silence was shattered now as if by the thunder of many guns. There was no time for easing themselves into gradual flight. Chet thrust forward on the ball-control, and the blast from their stern threw the ship as if it had been fired from a giant cannon. The self-compensating floor swung back and up; Chet's weight was almost unbearable as the ship beneath him leaped out and on, and the terrific blast that screamed and thundered urged this speeding shell to greater and still greater speed. And then, with the facility that that speed gave, Chet's careful hands moved a tiny metal ball within its magnetic cage, and the great ship bellowed from many ports as it followed the motion of that ball. Could an eye have seen the wild, twisting flight, it must have seemed as if pilot and ship had gone suddenly mad. The craft corkscrewed and whirled; it leaped upward and aside; and, as the glowing mass was thrown clear of the lookout, Chet's hand moved again to that maximum forward position, and again the titanic blast from astern drove them on and out. There were other shapes ahead, glowing lines of fire, luminous masses like streamers of cloud that looped themselves into contorted forms and writhed vividly until they straightened into sharp lines of speed that bore down upon the fleeing craft and the human food that was escaping these hungry snouts. Chet saw them dead ahead; he saw the out-thrust heads, each ending in a great suction-cup, the row of disks that were eyes blazing above, and the gaping maw below. He altered their course not a hair's breadth as he bore down upon them, while the monsters swelled prodigiously before his eyes. And the thunderous roar from astern came with never a break, while the ship itself ceased its trembling protest against the sudden blast and drove smoothly on and into the waiting beasts. There was a hardly perceptible thudding jar. They were free! And the forward lookouts showed only the brilliant fires of distant suns and one more glorious than the rest that meant a planet. * * * * * Chet turned at last to face Schwartzmann and his pilot where they had clung helplessly to a metal stanchion. Four or five others crept in from the cabin aft; their blanched faces told of the fear that bad gripped them--fear of the serpents; fear, too, of the terrific plunges into which the ship had been thrown. Chet Bullard drew the metal control-ball back into neutral and permitted himself the luxury of a laugh. "You're a fine bunch of highway-men," he told Schwartzmann; "you'll steal a ship you can't fly; then come up here above the R. A. level and get mixed up with those brutes. What's the idea? Did you think you would just hop over to the Dark Moon? Some little plan like that in your mind?"
