They were over an hour passing above this ocean, and had begun to wonder if it was greater in extent than Terra's Pacific. But finally they made out in the distance the dim blueness of the farther shore. "That's some ocean all right. Shows there's lots of water here on Two." "With those heavy rains there'd almost have to be. This'll be of special interest to colonists--means not only plenty of water, but if that stream was any example, there'll be lots of fish down there to start a big food industry later." About two hundred miles past the eastern shore of the ocean, they saw the blue of mountains in the decreasing distance. Soon Jon had to rise higher and higher to clear them safely. Some of the individual peaks seemed to be nearly five miles high, and one or two of them, almost at the range of visibility, the boys estimated to be even taller. "Probably lots of metals here," Jon commented. "I'll swing back and over them again, and let 'Annie' get to work." "Yes, this list says to report on metallic ores. Say, doesn't it seem funny to you that there are no people on a world as capable as this of supporting life? Wonder why?" "No telling. Pop says lots of Earthlike planets don't have any inhabitants capable of any sort of civilization. But that means more ready-made worlds for Terrans to colonize." Jon made their ship circle above the mountains while the boys took readings with the spectro-analyzer. Then they started on again. After almost another hour, when they were over one of the few desert places they had seen, Jon suddenly leaned forward with a little intake of breath that his brother noticed. "What's up?" "Not sure. But listen to 'Annie' click. From the reading, I think there must be some of that metal Pop was so positive about, down there somewhere." "The stuff for a new fuel?" "Yes. We don't know it'd be any good as fuel, but its atomic weight seems to be so high Pop was all excited when the spectrogram of this sun showed it. He said he felt sure we'd find it on at least one of these planets." "It'll take a lot of time to locate it exactly, won't it?" "Not too much, with the new gadgets they have for locating metal ores." Jon tried not to sound impatient with his brother's ignorance. "We've got one that lets us cruise around in the air and spot it fairly close, then land and find the exact place quite easily." "What sort of gadget?" Jon shrugged. "Don't know exactly how they work, but I can use one. Something like a spectroscope that works without first having to heat the metals into gas. Plus something like those old Geiger counters they used to trace radioactives. Plus some other ideas the technies put into them. It tells about them in one of our reelbooks there. You go get ours--I think it's in Bin 14, in the storeroom. Looks like a small black suitcase with carrying straps. Meanwhile, I'll get ready to set us down." "I'll hurry so's to be back to read the routine for you."
