"Emmett, here, has a junior-grade spaceship that he used to service those orbital telecast-relay stations of his. He'll tell you what it's like. I want it fitted with every sort of detection device that can be crammed into or onto it, and spotted above Keegark. It should, of course, be high enough to cover not only the Keegark area, but Konkrook, Kankad's, and the lower Hoork and Konk river-valleys."
"Yes, I get it." Hargreaves snatched up a phone, punched out a combination, and began talking rapidly into it in a low voice. After awhile, he hung up. "All right, Mr. Pearson—Colonel Pearson, I mean. Have your space-buggy sent around to the shipyard. My boys'll fix it up." He made a note on another piece of paper. "If we live through this, I'm going to have a couple of supra-atmosphere ships in service on this planet.... Now, general; I have a tentative set-up. We're going to need the Elmoran for patrol work south and east of Konkrook, and the Gaucho and Bushranger to the north and north-east, based on Kankad's. We'll keep the Aldebaran at Kankad's, and use her for emergencies. And we'll have patrols of light contragravity like this." He handed a map, with red-pencil and blue-pencil markings, along to von Schlichten. "Red are Kankad-based; blue are Konkrook-based."
"That looks all right," von Schlichten said. "There's another thing, though. We want scout-vehicles to cover the Keegark area with radiation-detectors. These geeks are quite well aware of radiation-danger from fissionables, but they're accustomed to the ordinary industrial-power reactors, which are either very lightly shielded or unshielded on top. We want to find out where Orgzild's bomb-plant is."
"Yes, general; as soon as we can get radiation detectors sent out to Kankad's, we'll have a couple of fast aircars fitted with them for that job."
"We have detectors, at our laboratory and reaction-plant," Kankad said. "And my people can make more, as soon as you want them." He thought for a moment. "Perhaps I should go to the town, now. I could be of more use there than here."
Kent Pickering, who had been talking with his experts at a table apart, returned.
"We've set up a program, general," he said. "It's going to be a lot harder than I'd anticipated. None of us seem to know exactly what we have to do in building one of those things. You see, the uranium or plutonium fission-bomb's been obsolete for over four hundred years. It was a classified-secret matter long after its obsolescence, because it hadn't been rendered any the less deadly by being superseded—there was that A-bomb that the Christian Anarchist Party put together at Buenos Aires in 378 A.E., for instance. And then, after it was declassified, it had been so far superseded that it was of only antiquarian interest; the textbooks dealt with it only in general terms. The principles, of course, are part of basic nuclear science; the secret of the A-bomb was just a bag of engineering tricks that we don't have, and which we will have to rediscover. Design of tampers, design of the chemical-explosive charges to bring subcritical masses together, case-design, detonating mechanism, things like that.
"The complete data on even the old Hiroshima and Nagasaki types is still in existence, of course. You can get it at places like the University of Montevideo Library, or Jan Smuts Memorial Library at Cape Town. But we don't have it here. We're detailing a couple of junior technicians to make a search of the library here on Gongonk Island, but we're not optimistic. We just can't afford to pass up any chance, even when it approaches zero-probability."
Von Schlichten nodded. "That's about what I'd expected," he said. "I suppose Gomes got his data out of one of the dustier storage-stacks at Jan Smuts or Montevideo, in the first place.... Well, I still want that bomb finished by yesterday afternoon, but since that's impractical, you'll have to take a little—but as little as possible—longer."
"What are we going to do about publicity on this?" Howlett, the personnel man. asked. "We don't want this getting out in garbled form—though how it could be made worse by garbling I couldn't guess—and having the troops watching the sky over their shoulders and going into a panic as soon as they saw something they didn't understand."
