"This DuQuesne tried for a long time to get the Rovolon and couldn't, so they built a space ship from Seaton's plans that they stole, and he carried off Dorothy Vaneman and Margaret Spencer, the girls that Seaton One and Crane One were going to marry--and they did marry them, afterward, too. Well, Dorothy kicked Perkins in the stomach, and the space ship ran away and kept on going until it got caught by the attraction of the Dark Mass that the First of Energy has always had so much trouble with, and while they were falling toward it that Perkins went crazy and tried to kill Margaret, but DuQuesne killed him instead, and then Seaton One caught up with them and rescued them and--" "Just a minute, son; there is no great hurry. How did Seaton One get way out there?" "Well, they had their big new space ship, the _Skylark of Space_, all built by then, and Seaton One had an object-compass set on DuQuesne, because he'd been watching him a long time since he'd been making lots of trouble for him. So Seaton One and Crane One followed the object-compass and found them and rescued them all but Perkins, because he was dead already. "They had an awful time getting away from the Dark Mass, but they did it, but they were about out of copper, so they had to hunt up a planet that had some. They landed on one that dinosaurs and things like that lived on, and got a lot more Rovolon, but didn't find any copper, so they hunted up more planets. One had poison gas instead of air, and another had people that were pure intellectuals, so that they had bodies whenever they wanted to, but not all the time. They pretty nearly dematerialized Seaton One and all the rest of them, and we're awfully glad they didn't. "Well, anyway, they got away, but they had an awful time, and after a while they saw the green suns of the Central System. There's lots of copper there, you know; so much that Grandfather Seaton wouldn't let me swim in the ocean last year when we were there because it was copper solution and it would have made me sick. They went to Osnome first, one of the inside worlds, and landed in a country named Mardonale. "They were bad people and wanted to kill Seaton One and steal his ship, and they had already captured Dunark, the Kofedix or crown prince of the other nation, Kondal. Then Dunark helped Seaton One get away, and they all went home with Dunark. But the _Skylark_ was pretty nearly ruined in the battle they had getting away from Mardonale, so Seaton One and Dunark built it over out of arenak, which was much better than the funny, soft steel they used to use in the old days. Of course, arenak doesn't amount to much beside the inoson we have now, but even Seaton One didn't know anything about inoson then.
