machines kept up their crooning.
“Maybe we should wait awhile,” said Mary, “before we leave the city.”
“I think we should,” said Jurgens.
“If he does come back, he’ll need us,” Sandra said.
“Edward,” Mary asked, “what do you think?”
“That we should wait,” he said. “At a time like this, we can’t desert the man. I can’t imagine he’ll come back, but if he should…”
They moved their camp into the alley, near the stairs that went down into the cavern where the machines sang softly to themselves. Each night the lonesome beast came out on the hills above the city and cried out its bitterness and lostness.
On the morning of the fourth day, after consulting the map that might have represented this part of the world, they left the city and found the westward continuation of the road they’d walked to reach it.

Early in the afternoon they reached the summit of the hills that ringed in the city and entered a grotesque world of erosion carving. The trail plunged downward through a colorful nightmare of earthen turrets, castles, battlements, towers and other fantastic shapes, tinted by the unending range of hues exhibited by the many geological layers of the different earths.
The going was slow; they did not try to hurry. The trail no longer could claim the distinction of being called a road. At times they would come out into the flatness of small floodplains, but then they would leave them to drop again into the weird, color-riotous madness of the tortured terrain.
Well before night closed in, they chose a camping place in the angle of a soaring clay cliff. Wood they found in tangled heaps of drift, deposited at some time long ago when great trees had come riding on the crests of the raging torrents that had carved the land. Wood, but no water. The day had not been excessively hot, however, and their canteens were almost full.
Vegetation grew sparse. Except for occasional patches of stout grasses and a few clumps of small conifers, hugging close against the ground, the sculptured earth was bare.
After supper they sat and watched the glory of the colors fade. When night fell, the stars came out bright and hard. Searching the skies, Lansing spotted familiar constellations. There could be no doubt, he told himself, that this place was Earth, but not the old familiar Earth that he had known. It was not another planet in another solar system; it was one of the alternate Earths that Andy had talked about, never for a moment suspecting there could be such other Earths.
The time factor bothered Lansing. With the constellations so little changed, if changed at all, the time differential between this Earth and the one that he had known must be no greater than a few tens of thousands of years at most. And yet, on this Earth, a great civilization had risen to heights as great or greater than had been the case on his Earth — had risen, developed, flourished and died. Could it be, he asked himself, that here Man had gotten an earlier start? Could the race of man here have developed some millions of years earlier? Was it possible, he wondered, that the crisis point between the two had been the dying out of mankind on his Earth, necessitating a starting over? That idea bothered him. If man died out on one Earth, what would be the chance of starting over again, of being given a second chance? Reason told him that the chance would be well nigh impossible.
“Edward,” Mary called, “you’ve scarcely said a word. What is going on?”
He shook his head. “A few random thoughts. Nothing of any great importance.”
“I’ll never feel quite right,” said Sandra, “for having left so soon. We really didn’t give the Brigadier much chance of getting back.”
“Why didn’t you speak up?” asked Mary. “You never said a word. We would have listened to you.”
“I was as anxious as the rest of you to get away. I couldn’t bear the thought of spending another day in the city.”
“For my part,” said Jurgens, “I think we wasted time waiting for him. He’s gone and gone for good.”
“What will happen to us now?” asked Sandra.
“Because the Parson and the Brigadier are gone?” asked Jurgens.
“Not that the two of them are gone, not those two alone. But there were six of us and now there are four. When will there be only three of us, or two?”
“We’ll have a better chance out here than we had in the city,” Mary said. “The city was a killer. We lost our people in the city.”
“We’ll be all right,” said Jurgens. “We’ll feel our way along. We’ll keep close watch and we won’t take chances.”
“But we don’t know where we’re going,” Sandra wailed.
“We never have,” said Jurgens. “Not since we were first thrown into this world have we known where we were going. Maybe the next bend down the trail will tell us. Maybe the day after tomorrow or the day after that.”
That night the Sniffler came back again. It sniffed all around the camp but did not intrude. They sat and listened to it. There was something comforting about its presence, as if an old friend had come back, as if a straying dog had come home again. There was no terror in the sniffling. The Sniffler had not entered the city with them; perhaps it liked the city no more than they had. But now that they were on the trail again, it had returned to join them.
Well before dark on the second day, they came on a tumbled ruin that sat on a small terrace above the trail.
“A place to spend the night,” said Jurgens.
They climbed the terrace and came to a rubble of fallen stones, soft sandstone blocks that at one time had formed a low wall around the small, ruined building that stood in the center of the rectangle formed by the scattered wall.
“Sandstone,” said Lansing. “Where could it have come from?”
“Over there,” said Jurgens, pointing to a low clay cliff that formed a backdrop for the place. “A strata of sandstone in the clay. There are signs, old signs, of quarrying.”
“Strange,” said Lansing.
“Not so strange,” Jurgens told him. “Here and there, along the way, there have been sandstone outcrops.”
“I hadn’t noticed.”
“You have to look sharp to see them. They are of the same color as the clay. I saw the first one by accident and then kept looking for them.”
The area within the shattered walls might have covered half an acre, scarcely more. The ruin standing in its center at one time had been a one-room structure. The roof had fallen in, part of the walls had tumbled down. Some broken crockery was scattered about on what once had been a well-trodden earthen floor, and in one corner of it Jurgens found a tarnished, battered metal pot.
“A stopping place for travelers,” said Sandra. “A caravansary.”
“Or a fort,” said Jurgens.
“A fort against what?” asked Lansing. “There is nothing here to fort up against.”
“At one time there might have been,” the robot said.
Outside the ruined building they found evidence of an old campfire, a bed of ash and smoke-blackened stones placed at intervals around it, perhaps to serve as cooking hearths. Beside the fire site was piled some driftwood.
“The last party through,” said Jurgens, “gathered more than was needed. It should last us out the night.”
“How about water?” Lansing asked.
“I think we have enough,” said Mary. “We’ll have to find some tomorrow.”
Lansing walked out to the ruined wall and stood, looking out over the monstrously sculptured terrain.
