In a few moments he was back, a molecular pistol in one hand, and suspended in front of him on nothing but a ray of ionized air, to all appearances, a cylindrical apparatus, with a small cubical base. The cylinder was about four feet long, and the cubical box about eighteen inches on a side. "What is that, and what supports it?" asked the Talsonian scientists in surprise. "The thing is supported by a ray which directs the molecules of a small bar in the top clamp, driving it up," explained Morey, "and that is the generator." "That! Why it is hardly as big as a man!" exclaimed the Talsonian. "Nevertheless, it can generate a billion horsepower. But you couldn't get the power away if you did generate it." He turned toward Arcot, and called to him. "Arcot--set it down and let her rip on about half a million horsepower for a second or so. Air arc. Won't hurt it--she's made of lux and relux." Arcot grinned, and set it on the ground. "Make an awful hole in the ground." "Oh--go ahead. It will satisfy this fellow, I think," replied Morey. Arcot pulled a very thin lux metal cord from his pocket, and attached one end of a long loop to one tiny switch, and the other to a second. Then he adjusted three small dials. The wire in hand, he retreated to a distance of nearly two hundred feet, while Morey warned the Talsonians back. Arcot pulled one end of his cord. Instantly a terrific roar nearly deafened the men, a solid sheet of blinding flame reached in a flaming cone into the air for nearly fifty feet. The screeching roar continued for a moment, then the heat was so intense that Arcot could stand no more, and pulled the cord. The flame died instantly, though a slight ionization clung briefly. In a moment it had cooled to white, and was cooling slowly through orange--red deep--red-- The grass for thirty feet about was gone, the soil for ten feet about was molten, boiling. The machine itself was in a little crater, half sunk in boiling rock. The Talsonians stared in amazement. Then a sort of sigh escaped them and they started forward. Arcot raised his molecular pistol, a blue green ray reached out, and the rock suddenly was black. It settled swiftly down, and a slight depression was the only evidence of the terrific action. Arcot walked over the now cool rock, cooled by the action of the molecular ray. In driving the molecules downward, the work was done by the heat of these molecules. The machine was frozen in the solid lava. "Brilliant idea, Morey," said Arcot disgustedly. "It'll be a nice job breaking it loose." Morey stuck the lux metal bar in the top clamp, walked off some distance, and snapped on the power. The rock immediately about the machine was molten again. A touch of the molecular pistol to the lux metal bar, and the machine jumped free of the molten rock. Morey shut off the power. The machine was perfectly clean, and extremely hot. "And your ship is made of that stuff!" exclaimed the Talsonian scientist. "What will destroy it?"
