conquered the strange atmospheres and bacteria and gravitations, until now the races of man held sway over all the sun's eight wheeling worlds. And it was from this Earth, a thousand centuries before, that there had ventured out the first discoverers' crude little space-boats, whose faulty gravity-screens and uncertain controls contrasted strangely with the mighty leviathans that flashed between the planets now. Abruptly I was aroused from my musings by the sharp ringing of a bell at my elbow. "The telestereo," I said to Hal Kur. "Take the controls." As he did so I stepped over to the telestereo's glass disk, inset in the room's floor, and touched a switch beside it. Instantly there appeared standing upon the disk, the image of a man in the blue and white robe of the Supreme Council, a life-size and moving and stereoscopically perfect image, flashed across the void of space to my apparatus by means of etheric vibrations. Through the medium of that projected image the man himself could see and hear me as well as I could see and hear him, and at once he spoke directly to me. "Jan Tor, Captain of Interplanetary Patrol Cruiser 79388," he said, in the official form of address. "The command of the Supreme Council of the League of Planets, to Jan Tor. You are directed to proceed with all possible speed to Earth, and immediately upon your arrival there to report to the Council, at the Hall of Planets. Is the order heard?" "The order is heard and will be obeyed," I answered, making the customary response, and the figure on the disk bowed, then abruptly vanished. I turned at once to a speaking-tube which connected with the cruiser's screen rooms. "Make all speed possible to reach Earth," I ordered the engineer who answered my call. "Throw open all the left and lower screens and use the full attraction of the sun until we are within twenty thousand miles of Earth; then close them and use the attraction of Jupiter and Neptune to brake our progress. Is the order heard?" When he had acknowledged the command I turned to Hal Kur. "That should bring us to Earth within the hour," I told him, "though the Power alone knows what the Supreme Council wants with a simple patrol-captain." His laugh rumbled forth. "Why, here's unusual modesty, for you! Many a time I've heard you tell how the Eight Worlds would be run were Jan Tor of the Council, and now you're but 'a simple patrol-captain!'" With that parting gibe he slid quickly down through
