“You think we’ll ever have it rebuilt?” Morrison asked. “It makes me sick to look at it.”

“In time,” O’Neill answered. “Assuming, of course, that we get industrial control back. And assuming that anything remains to work with. At best, it’ll be slow. We’ll have to inch out from the settlements.”

To the right was a human colony, tattered scarecrows, gaunt and emaciated, living among the ruins of what had once been a town. A few acres of barren soil had been cleared; drooping vegetables wilted in the sun, chickens wandered listlessly here and there, and a fly-bothered horse lay panting in the shade of a crude shed.

“Ruins-squatters,” O’Neill said gloomily. “Too far from the network—not tangent to any of the factories.”

“It’s their own fault,” Morrison told him angrily. “They could come into one of the settlements.”

“That was their town. They’re trying to do what we ‘re trying to do—build up things again on their own. But they’re starting now, without tools or machines, with their bare hands, nailing together bits of rubble. And it won’t work. We need machines. We can’t repair ruins; we’ve got to start industrial production.”

Ahead lay a series of broken hills, chipped remains that had once been a ridge. Beyond stretched out the titanic ugly sore of an H-bomb crater, half filled with stagnant water and slime, a disease-ridden inland sea.

And beyond that—a glitter of busy motion.

“There,” O’Neill said tensely. He lowered the helicopter rapidly. “Can you tell which factory they’re from?”

“They all look alike to me,” Morrison muttered, leaning over to see. “We’ll have to wait and follow them back, when they get a load.”

“If they get a load,” O’Neill corrected.

The autofac exploring crew ignored the helicopter buzzing overhead and concentrated on its job. Ahead of the main truck scuttled two tractors; they made their way up mounds of rubble, probes burgeoning like quills, shot down the far slope and disappeared into a blanket of ash that lay spread over the slag. The two scouts burrowed until only their antennas were visible. They burst up to the surface and scuttled on, their treads whirring and clanking.
