It was larger than the Earth, and of a somewhat stronger gravitation. Although its climate was bitterly cold, even in its short daytime, it supported a luxuriant but outlandish vegetation. Its atmosphere, while rich enough in oxygen and not really poisonous, was so rank with indescribably fetid vapors as to be scarcely breatheable. But these things bothered the engineers not at all. Paying no attention to temperature or to scenery and without waiting for chemical analysis of the air, the space-suited mechanics leaped to their tasks; and in only a little more time than had been mentioned by the chief engineer the hull and giant frame of the super-ship were as staunch as of yore. "All right, Skipper!" came finally the welcome word. "You might try her out with a fast hop around this world before you shove off in earnest." Under the fierce blast of her projectors the vessel leaped ahead, and time after time, as Rodebush hurled her mass upon tractor beam or pressor, the engineers sought in vain for any sign of weakness. The strange planet half girdled and the severest tests passed flawlessly, Rodebush reached for his neutralizer switches. Reached and paused, dumbfounded, for a brilliant purple light had sprung into being upon his panel and a bell rang out insistently. "What the hell!" Rodebush shot out an exploring beam along the detector line and gasped. He stared, mouth open, then yelled: "_Roger_ is here, rebuilding his planetoid! STATIONS ALL!" CHAPTER 17 ROGER CARRIES ON As has been intimated, gray Roger did not perish in the floods of Nevian energy which destroyed his planetoid. While those terrific streamers of force emanating from the crimson obscurity surrounding the amphibians' space-ship were driving into his defensive screens he sat impassive and immobile at his desk, his hard gray eyes moving methodically over his instruments and recorders. When the clinging mantle of force changed from deep red into shorter and even shorter wave-lengths, however: "Baxter, Hartkopf, Chatelier, Anandrusung, Penrose, Nishimura, Mirsky ..." he called off a list of names. "Report to me here at once!" "The planetoid is lost," he informed his select group of scientists when they had assembled, "and we must abandon it in exactly fifteen minutes, which will be the time required for the robots to fill this first section with our most necessary machinery and instruments. Pack each of you one box of the things he most wishes to take with him, and report back here in not more than thirteen minutes. Say nothing to anyone else." They filed out calmly, and as they passed out into the hall Baxter, perhaps a trifle less case-hardened than his fellows, at least voiced a thought for those they were so brutally deserting. "I say, it seems a bit thick to dash off this way and leave the rest of them; but still, I suppose...."
