"The swiftest thing that ever was _thought_! The most irresistible thing, _thought_, for nothing can stop its progress. The most destructive thing, _thought_. Thought, the greatest constructor, the greatest destroyer, the product of mind, and producer of powers, the greatest of powers. Thought is controlled by the mind. Let us call it _Thought_!" "Excellent, Arcot, excellent. The _Thought_, the controller of the powers of the cosmos!" cried Morey. "But the _Thought_ has not been christened, save in battle, and then it had no name. Let us emblazen its name on it now," suggested Wade. Stopping their motion through space, but maintaining a time field that permitted them to work without consuming precious time, Arcot formed some more cosmium, but now he subjected it to a special type of converted field, and into the cosmium, he forced some light photons, half bound, half free. The fixture he formed into the letters, and welded forever on the gigantic prow of the ship, and on its huge sides. _Thought_, it stood in letters ten feet high, made of clear transparent cosmium, and the golden light photons, imprisoned in it, the slowly disintegrating lux metal, would cause those letters to shine for countless aeons with the steady golden light they now had. The _Thought_ continued on now, and as they slowed their progress for Ortol, they saw that messengers of Thett had barely arrived. The fort here too had been razed to the ground, and now they were concentrating over the largest city of Ortol. Their rays were beating down on the great ray screen that terrestrial engineers had set up, protecting the city, as Earth had been protected. But the fleet that stood guard was small, and was rapidly being destroyed. A fort broke free, and plunged at last for the ray screen. Its relux walls glowed a thousand colors as the tremendous energy of the ray-screen struck them--but it was through! A molecular ray reached down for the city--and stopped halfway in a tremendous coruscating burst of light and energy. Yet there was none of the sheen of the ray screen. Merely light. The fort was still driving downward. Then suddenly it stopped, and the side dented in like the side of a can some one has stepped on, and it came to sudden rest against an invisible, impenetrable barrier. A molecular reached down from somewhere in space, hit the ray screen of Ortol, which the Thessians had attacked for hours, and the screen flashed into sudden brilliance, and disappeared. The ray struck the Thessian fort, and the fort burst into tremendous opalescence, while the invisible barrier the ray had struck was suddenly a great sheet of flaming light. In less than half a second the opalescence was gone, the fort shuddered, and shrieked out of the planet's atmosphere, a mass of lux now, and susceptible to the moleculars. And everything that lived within that fort had died instantly and painlessly.
