George Craig had finished checking it when Lake arrived. He looked up from his instruments, remarkably similar in appearance to a sketch of the old George Ord—a resemblance that had been passed down to him by his mother—and said:
“The entire circuit is either gone or ready to go. It’s already operated for a lot longer than it should have.”
“It doesn’t matter,” Lake said. “It’s served its purpose. We won’t rebuild it.”
George watched him questioningly.
“It’s served its purpose,” he said again. “It didn’t let us forget that the Gerns will come again. But that isn’t enough, now. The first signal won’t reach Athena until the year two thirty-five. It will be the dead of Big Winter again then. They’ll have to fight the Gerns with bows and arrows that the cold will make as brittle as glass. They won’t have a chance.”
“No,” George said. “They won’t have a chance. But what can we do to change it?”
“It’s something I’ve been thinking about,” he said. “We’ll build a hyperspace transmitter and bring the Gerns before Big Winter comes.”
“We will?” George asked, lifting his dark eyebrows. “And what do we use for the three hundred pounds of copper and five hundred pounds of iron we would have to have to make the generator?”
“Surely we can find five hundred pounds of iron somewhere on Ragnarok. The north end of the plateau might be the best bet. As for the copper—I doubt that we’ll ever find it. But there are seams of a bauxite-like clay in the Western hills—they’re certain to contain aluminum to at least some extent. So we’ll make the wires of aluminum.”
“The ore would have to be refined to pure aluminum oxide before it could be smelted,” George said. “And you can’t smelt aluminum ore in an ordinary furnace—only in an electric furnace with a generator that can supply a high amperage. And we would have to have cryolite ore to serve as the solvent in the smelting process.”
“There’s a seam of cryolite in the Eastern Hills, according to the old maps,” said Lake. “We could make a larger generator by melting down everything we have. It wouldn’t be big enough to power the hyperspace transmitter but it should be big enough to smelt aluminum ore.”
George considered the idea. “I think we can do it.”
“How long until we can send the signal?” he asked.
“Given the extra metal we need, the building of the generator is a simple job. The transmitter is what will take years—maybe as long as fifty.”
Fifty years. …
“Can’t anything be done to make it sooner?” he asked.
“I know,” George said. “You would like for the Gerns to come while you’re still here. So would every man on Ragnarok. But even on Earth the building of a hyperspace transmitter was a long, slow job, with all the materials they needed and all the special tools and equipment. Here we’ll have to do everything by hand and for materials we have only broken and burned-out odds and ends. It will take about fifty years—it can’t be helped.”
Fifty years … but that would bring the Gerns before Big Winter came again. And there was the rapidly increasing chance that a Gern cruiser would at any day intercept the first signals. They were already more than halfway to Athena.
“Melt down the generator,” he said. “Start making a bigger one. Tomorrow men will go out after bauxite and cryolite and four of us will go up the plateau to look for iron.”
Lake selected Gene Taylor, Tony Chiara and Steve Schroeder to go with him. They were well on their way by daylight the next morning, on the shoulder of each of them a mocker which observed the activity and new scenes with bright, interested eyes.
They traveled light, since they would have fresh meat all the way, and carried herbs and corn only for the mockers. Once, generations before, it had been necessary for men to eat herbs to prevent deficiency diseases but now the deficiency diseases, like Hell Fever, were unknown to them.
They carried no compasses since the radiations of the two suns constantly created magnetic storms that caused compass needles to swing as much as twenty degrees within an hour. Each of them carried a pair of powerful binoculars, however; binoculars that had been diamond-carved from the ivory-like black unicorn horn and set with lenses and prisms of diamond-cut quartz.
The foremost bands of woods goats followed the advance of spring up the plateau and they followed the woods goats. They could not go ahead of the goats—the goats were already pressing close behind the melting of the snow. No hills or ridges were seen as the weeks went by and it seemed to Lake that they would walk forever across the endless rolling floor of the plain.
Early summer came and they walked across a land that was green and pleasantly cool at a time when the vegetation around the caves would be burned brown and lifeless. The woods goats grew less in number then as some of them stopped for the rest of the summer in their chosen latitudes.
They continued on and at last they saw, far to the north, what seemed to be an almost infinitesimal bulge on the horizon. They reached it two days later; a land of rolling green hills, scarred here and there with ragged outcroppings of rock, and a land that climbed slowly and steadily higher as it went into the north.
They camped that night in a little vale. The floor of it was white with the bones of woods goats that had tarried too long the fall before and got caught by an early blizzard. There was still flesh on the bones and scavenger rodents scuttled among the carcasses, feasting.
“We’ll split up now,” he told the others the next morning.
He assigned each of them his position; Steve Schroeder to parallel his course thirty miles to his right, Gene Taylor to go thirty miles to his left, and Tony
