"All right." He had always been like that--one minute in a black rage, the next perfectly agreeable. He now led the way up to a cliff hanging over the sea. "There," said Garth, "is the _Comet_. Our greatest step in conquering distance. After I've tried it out, we can go in a year to the end of the universe. But, for a starter, how about a thousand light-years around Rigel in six months?" His eyes were afire. Then he calmed down. "Anything I can show you?" [Note: Editor's Note: The manuscript, of which a translation is here presented, was discovered by the rocket-ship expedition to the moon three years ago. It was found in its box by the last crumbling ruins of the great bridge mentioned in the narrative. Its final translation is a tribute at once to the philological skill of the Earth and to the marvelous dictionary provided by Dunal, the Lunarian. Stars and lunar localities will be given their traditional Earth names; and measures of time, weight, and distance have been reduced, in round numbers, to terrestrial equivalents. Of the space ship described, the _Comet_, no trace has been found. It must be buried under the rim of one of the hundreds of nearby Lunar craters--the result, as some astronomers have long suspected and as Dunal's story verifies, of a great swarm of meteors striking the unprotected, airless moon.] * * * * * I had seen the _Comet_ before, but never so close. With a hull of shining helio-beryllium--the new light, inactive alloy of a metal and a gas--the ship was a cylinder about twenty feet long, by fifteen in diameter, while a pointed nose stretched five feet farther at each end. Fixed in each point was a telescopic lens, while there were windows along the sides and at the top--all made, Garth informed us, of another form of the alloy almost as strong as the opaque variety. Running half-way out each end were four "fins" which served to apply the power driving the craft. A light inside showed the interior to be a single room, ten feet high at the center of its cylindrical ceiling, with a level floor. "How do you know this will be the bottom?" I asked, giving the vessel a shove to roll it over. But it would not budge. Garth laughed. "Five hundred pounds of mercury and the disintegrators are under that floor, while out in space I have an auxiliary gravity engine to keep my feet there."
