Instantly Korus Kan opened wide the power-controls, and with a mounting humming roar our great ship went rapidly into its highest speed, its great generators flinging it on through the ether at a thousand times the velocity of light, propelling it headlong onward toward the galaxy that lay still far ahead, its mighty disk-like mass of shining suns stretched across the blackness of space before us. And behind us rushed the great swarm, too, racing on after us and toward the galaxy still. I knew that the speed of that mighty swarm of ships must be inconceivably greater than that of our own, since we ourselves had seen them on our charts racing in toward the galaxy from outer space with velocity unthinkable, a velocity which we had thought could only be due to some great ether-current, and which they had only slackened as they drew near the galaxy. There was a slender chance, though, that we might yet escape, and now as we rushed on toward the galaxy in headlong flight I turned quickly to the speech-projection instrument beside me, pressing a button in its base. A moment later there came from it a clear, twanging voice. "General Patrol Headquarters at Canopus," it announced, and swiftly I responded. "Dur Nal, Captain of Patrol Squadron 598-77, speaking," I said. "I desire to report the discovery of a swarm of some five thousand strange space-ships which have appeared out of outer space, heading toward the galaxy. These ships are apparently capable of immense speeds and are armed with a form of death-beam unfamiliar to us, but extremely deadly in operation. On discovering these ships we were attacked by them and all of my squadron except my own ship destroyed. Our own ship is now being chased inward toward the galaxy, heading in the general direction of the Cancer cluster, and though the swarm is gradually overhauling us we may be able to escape. From the size, number and deadly armament of these alien ships it is apparent that they contemplate a general attack upon our universe." There was a moment's pause when I had finished, and then from the speech-instrument there came the metallic voice again, as calm as though I had made only a routine report of position and progress. "Order of Lacq Larus, Chief of the Interstellar Patrol, to Dur Nal. You will make every effort to elude the pursuing swarm, and if you can do so will endeavor to draw it into the Cancer cluster. All the cruisers of the Interstellar Patrol will be assembled inside the cluster as swiftly as possible, and if you are successful in drawing the pursuing swarm inside it will be possible for our fleet to fall upon it in an unexpected attack, and destroy these invaders, whatever their source or purpose, before they can obtain a foothold in the galaxy. You have the order?" "I have the order," I replied, as calmly as possible, and with a word of acknowledgment the twanging voice ceased.
