As the door slammed shut behind him, though, I forgot all else for the moment and concentrated all my attention on the ship's progress. It was my habit to act as pilot of my own cruiser, whenever possible, and for the time being I was quite alone in the round little pilot-house, or conning-tower, set on top of the cruiser's long, fishlike hull. Only pride, though, kept me from summoning an assistant to the controls, for the sun was pulling the cruiser downward with tremendous velocity, now, and as we sped down past Earth's shining little moon we ran into a belt of meteorites which gave me some ticklish moments. At last, though, we were through the danger zone, and were dropping down toward Earth with decreasing speed, as the screens were thrown open which allowed the pull of Neptune and Jupiter to check our progress. A touch of a button then brought a pilot to replace me at the controls, and as we fell smoothly down toward the green planet below I leaned out the window, watching the dense masses of interplanetary shipping through which we were now threading our way. It seemed, indeed, that half the vessels in the solar system were assembled around and beneath us, so close-packed was the jam of traffic. There were mighty cargo-ships, their mile-long hulls filled with a thousand products of Earth, which were ponderously getting under way for the long voyages out to Uranus or Neptune. Sleek, long passenger-ships flashed past us, their transparent upper-hulls giving us brief glimpses of the gay groups on their sunlit decks. Private pleasure-boats were numerous, too, mostly affairs of gleaming white, and most of these were apparently bound for the annual Jupiter-Mars space-races. Here and there through the confusion dashed the local police-boats of Earth, and I caught sight of one or two of the long black cruisers of the Interplanetary Patrol, like our own, the swiftest ships in space. At last, though, after a slow, tortuous progress through the crowded upper levels, our craft had won through the jam of traffic and was swooping down upon the surface of Earth in a great curve. * * * * * In a panorama of meadow and forest, dotted here and there with gleaming white cities, the planet's parklike surface unrolled before me as we sped across it. We rocketed over one of its oceans, seeming hardly more than a pond to my eyes after the mighty seas of Jupiter and the vast ice-fringed oceans of Neptune; and then, as we flashed over land again, there loomed up far ahead the gigantic white dome of the great Hall of Planets, permanent seat of the Supreme Council and the center of government of the Eight Worlds. A single titanic structure of gleaming white, that reared its towering dome into the air for over two thousand feet, it grew swiftly larger as we raced on toward it. In a moment we were beside it, and the cruiser was slanting down toward the square landing-court behind the great dome.
