Newlin adjusted the throat microphones and headsets in their plastic helmets to make for easier conversation. But for a while, neither could talk. They sat and gasped, yearning for a breath of fresh, unreclaimed air. Water supplies were low, and already Newlin had established iron rations. Drinking by tubes was difficult in the helmets and the water was warm and foul. "You're lost?" Songeen asked at last. Newlin nodded. He produced a wrinkled, battered map. "I can't even trust the compass. I don't know where we are." The girl took the map in her gloved hands and peered intently through her face-mask. One finger traced a tiny circle in the film of dust. "I know," she said. "We are somewhere about here. And over there--" she indicated a direction behind Newlin--"is the city from which my people came." Newlin was startled. The directional instinct with which all Venusians are endowed was familiar enough, yet he would have sworn the girl was not from the enfeebled and mutant races of the veiled planet. She was, at once, more human--and more remote. Songeen guessed his doubt. Through the fused quartz faceplate, her angular features wore a curious, faint smile. "No, not Venusian. This was an--an outpost. A colony and a quarantine station. The city was abandoned long ago. Long before the atomic holocaust my people fled. Eons have passed. Everything is now in ruins--if even ruins remain. See, it is not marked on the map. Not even as ruins. But we have unusual race-memory. I can see the fabulous towers and arsenals, the terraced gardens and the palaces--as if they still stood today as they were in that vanished yesterday. And we have the homing instinct. It was my people who gave it to the Venusians. The one thing of value that still remains to them." Newlin was still dubious. "Unless you're dreaming." Her finger jabbed at the map. "We are here," she insisted. "And if you care to search and dig, the city is probably still there, as it was a million years ago." "Would there be water in your ruined city?" Newlin asked. "Who knows? The wells are probably all filled with sand now. Or gone dry, or become contaminated. There is always much radioactivity near the ruined cities. They were primary targets when the peoples of Venus destroyed themselves. Even this desert is mute evidence of the holocaust; if one needs evidence. My people fled before that madness, because they anticipated it." Newlin snorted. The pre-holocaust Venusians were purely legendary. No written records could exist, amid such conditions as must have followed the ancient wars. Science knew that at least half a million years had passed since Venus was a fair green planet peopled with hearty, beautiful, ease-loving races. Half a million years since the surface people had even looked upon the sun.
