"Hmmm--sensible way to figure. A man after my own heart. How does he plan to restock his bank account?" "By mining on Mercury. He does it regularly--sort of a commuter. Out here his power bills eat it up. On Mercury he goes in for potassium, and sells the power he collects in cooling his dome, of course. He's a good miner, and the old fool can make money down there." Like any really skilled operator, Cole had been sending Morse messages while he talked. Now he sat quiet waiting for the reply, glancing at the chronometer. "I take it he's not after money--just after fun," suggested Buck. "Oh, no. He's after money," replied Cole gravely. "You ask him--he's going to make his eternal fortune yet by striking a real bed of jovium, and then he'll retire." "Oh, one of that kind." "They all are," Cole laughed. "Eternal hope, and the rest of it." He listened a moment and went on. "But old Nichols is a first-grade engineer. He wouldn't be able to remake that bankroll every time if he wasn't. You'll see his Dome out there on Pluto--it's always the best on the planet. Tip-top shape. And he's a bit of an experimenter too. Ah--he's with us." Nichols' ragged signals were coming through--or pounding through. They were worse than usual, and at first Kendall and Cole couldn't make them out. Then finally they got them in bursts. The man was excited, and his bad key-work made it worse. "--Randing stopped. They got him I think. He said--th--ship as big--a--nsport. Said it wa--eaded my--ay. Neutrons--on instruments--he's coming over the horizon--it's huge--war ship I think--register--instru--neutrons--." Abruptly the signals were blanked out completely. * * * * * Cole and Kendall sat frozen and stiff. Each looked at the other abruptly, then Kendall moved. From the receiver, he ripped out the recording coil, and instantly jammed it into the analyzer. He started it through once, then again, then again, at different tone settings, till he found a very shrill whine that seemed to clear up most of Nichols' bad key-work. "T-247--T-247--Emergency. Emergency. Randing reports the--over his horizon. Huge--ip--reign manufacture. Almost spherical. Randing's stopped. They got him I think. He said the ship was as big as a transport. Said it was headed my way. Neutrons--ont--gister--instruments. I think--is h--he's coming over the horizon. It's huge, and a war ship I think--register--instruments--neutrons."
