Greel thought. An almost man-scent. And words. Could it be that the fire things were men? They would be strange men, much unlike the People. But the taletellers sung of men in ancient times that had strange powers and forms. Might not these be such men? Here, in the Oldest Tunnels, where the legends said the Old Ones had created the People-might not such men still dwell here?
Yes.
Greel stirred. He moved slowly from where he lay, raising himself to a crouching position to squint at the curve ahead. A silent snap brought H’ssig back to safety from the fiery tunnel beyond the curve.
There was one way to make sure, Creel thought. Trembling, he reached out cautiously with his mind.
Von der Stadt had adapted to Earth’s gravity a lot more successfully than Cif-fonetto. He reached the floor of the tunnel quickly, and waited impatiently while his companion climbed down from the platform.
Ciffonetto let himself drop the last foot or so, and landed with a thud. He looked up at the platform apprehensively. "I just hope I can make it back up," he said.
Von der Stadt shrugged. "You were the one who wanted to explore all the tunnels."
"Yes," said Ciffonetto, shifting his gaze from the platform to look around him. "And I still do. Down here, in these tunnels, are the answers we’re seeking."
"That’s your theory, anyway," Von der Stadt said. He looked in both directions, chose one at random, and moved forward, his flashlight beam spearing out before him. Ciffonetto followed a half-step behind.
The tunnel they entered was long, straight, and empty.
"Tell me," Von der Stadt said in an offhand manner as they walked, "even if your survivors did make it through the war in shelters, wouldn’t they have been forced to surface eventually to survive? I mean-how could anyone actually live down here?" He looked around the tunnel with obvious distaste.
"Have you been taking lessons from Nagel or something?" Ciffonetto replied. "I’ve heard that so often I’m sick of it. I admit it would be difficult. But not impossible. At first, there would be access to large stores of canned goods. A lot of that stuff was kept in basements. You could get to it by tunnelling. Later, you could raise food. There are plants that will grow without light. And there would be insects and boring animals too, I imagine."
"A diet of bugs and mushrooms. It doesn’t sound too healthy to me."
Ciffonetto stopped suddenly, not bothering to reply. "Look there," he said, pointing with his flashlight.
The beam played over a jagged break in the tunnel wall. It looked as though someone had smashed through the stone a long time ago.
Von der Stadt’s flash joined Ciffonetto’s to light the area better. There was a passage descending from the break. Ciffonetto moved towards it with a start.
"What the hell do you say to this, Von der Stadt?" he asked, grinning. He stuck head and flashlight into the crude tunnel, but re-emerged quickly.
"Not much there," he said. "The passage is caved in after a few feet. But still, it confirms what I’ve been saying."
Von der Stadt looked vaguely uneasy. His free hand drifted to the holstered pistol at his side. "I don’t know," he said.
"No, you don’t," said Ciffonetto, triumphantly. "Neither does Nagel. Men have lived down here. They may still live here. We’ve got to organize a more efficient search of the whole underground system."
He paused, his mind flickering back to Von der Stadt’s argument of a few seconds earlier. "As for your bugs and mushrooms, men can learn to live on a lot of things.
Men adapt. If men survived the war-and this says they did-then they survived the aftermath, I’ll wager."
"Maybe," Von der Stadt said. "I can’t see what you are so hot on discovering survivors for anyway, though. I mean, the expedition is important and all that. We’ve got to re-establish spaceflight, and this is a good test for our new hardware. And I guess you scientists can pick up some good stuff for the museums. But humans? What did Earth ever get us besides the Great Famine?"
Ciffonetto smiled tolerantly. "It’s because of the Great Famine that we want to find humans," he said. He paused. "We’ve got enough to entice even Nagel now. Let’s head back."
He started walking back in the direction they had come, and resumed talking. "The Great Famine was an unavoidable result of the war on Earth," he said. "When supplies stopped coming, there was absolutely no way to keep all the people in the lunar colony alive. Ninety per cent starved.
"Luna could be made self-sufficient, but only with a very small population. That’s what happened. The population adjusted itself. But we recycled our air and our water, grew foods in hydroponic tanks. We struggled, but we survived. And began to rebuild.
"But we lost a lot. Too many people died. Our genetic pool was terribly small, and not too diverse. The colony had never had a lot of racial diversity to begin with.
