The spacemen spent a cramped and almost sleepless night. Although in his training on Terra, on his trial trips to Mars and the harsh Lunar valleys, Raf had known weird surroundings and climates, inimical to his kind, he had always been able to rest almost by the exercise of his will. But now, curled in his roll, he was alert to every sound out of the moonless night, finding himself listening—for what he did not know.  
Though there were sounds in plenty. The whistling call of some night bird, the distant lap, lap of water which he associated with the river curving through the long-deserted city, the rustle of grass as either the wind or some passing animal disturbed it.[96]
 
"Not the best place in the world for a nap," Soriki observed out of the dark as Raf wriggled, trying to find a more comfortable position. "I'll be glad to see these bandaged boys on the ground waving good-bye as we head away from them—fast—"
 
"Those weren't animals they killed—back on that island." Raf brought out what was at the heart of his trouble.
 
"They wore fur instead of clothing." Soriki's reply was delivered in a colorless, even voice. "We have apes on Terra, but they are not men."
 
Raf stared up at the sky in which stars were sprinkled like carelessly flung dust motes. "What is a 'man'?" he returned, repeating the classical question which was a debating point in all the space training centers.
 
For so long his kind had wondered that. Was a "man" a biped with certain easily recognized physical characteristics? Well, by that ruling the furry things which had fled fruitlessly from the flames of the globe might well qualify. Or was "man" a certain level of intelligence, no matter what form housed that intelligence? They were supposed to accept the latter definition. Though, in spite of the horror of prejudice, Raf could not help but believe that too many Terrans secretly thought of "man" only as a creature in their own general image. By that prejudiced rule it was correct to accept the aliens as "men" with whom they could ally themselves, to condemn the furry people because they were not smooth-skinned, did not wear clothing, nor ride in mechanical transportation.
 
Yet somewhere within Raf at that moment was the nagging feeling that this was all utterly wrong, that the Terrans had not made the right choice. And that now "men" were not standing together. But he had no intention of spilling that out to Soriki.
 
"Man is intelligence." The com-tech was answering the question Raf had almost forgotten that he had asked the moment before. Yes, the proper conventional[97] reply. Soriki was not going to be caught out with any claim of prejudice.
 
Odd—when Pax had ruled, there were thought police and the cardinal sin was to be a liberal, to experiment, to seek knowledge. Now the wheel had turned—to be conservative was suspect. To suggest that some old ways were better was to exhibit the evil signs of prejudice. Raf grinned wryly. Sure, he had wanted to reach the stars, had fought doggedly to come to the very spot where he now was. So why was he tormented now with all these second thoughts? Why did he feel every day less akin to the men with whom he had shared the voyage? He had had wit enough to keep his semirebellion under cover, but since he had taken the flitter into the morning sky above the landing place of the spacer, that task of self-discipline was becoming more and more difficult.
 
"Did you notice," the com-tech said, going off on a new track, "that these painted boys were not too quick about blasting along to their strongbox? I'd say that they thought some bright rocket jockey might have rigged a surprise for them somewhere in there—"
 
Now that Soriki mentioned it, Raf remembered that the alien party who had gone into the city had huddled together, and that several of the black-and-white warriors had fanned out ahead as scouts might in enemy territory.
 
"They didn't go any farther than that building to the west either."
 
That Raf had not noticed, but he was willing to accept Soriki's observation. The com-tech had a ready eye for details. He'd better pay closer attention himself. This was no time to explore the why and wherefore of his present position. So, if they went no farther than that building, it would argue that the aliens themselves didn't care to go about here after nightfall. For he was certain that the isolated structure Soriki had pointed out was not the treasure house they had come to loot.[98]
 
The night wore on and sometime during it Raf fell asleep. But the two or three hours of restless, dream-filled unconsciousness was not what he needed, and he blinked in the dawn with eyes which felt as if they were filled with hot sand. In the first gray light a covey of winged things, which might or might not have been birds, arose from some roosting place within the city, wheeled three times over the building, and then vanished out over the countryside.
 
Raf pulled himself out of his roll, made a sketchy toilet with the preparations in a belt kit, and looked about with little favor for either the scene or his part in it. The globe, sealed as if ready for a take-off, was some distance away, but installed about halfway between it and the flitter were two of the alien warriors. Perhaps they had changed watches during the night. If they had not, they could go without sleep to an amazing degree, for as Raf walked in a circle about the flyer to limber up, they watched him closely, nor did their grips on their odd weapons loosen. And he had a very clear idea that if he stepped over some invisible boundary he would be in for trouble.
 
When he came back to the flitter, Soriki was awake and stretching.
 
"Another day," the com-tech drawled. "And I could do with something besides field rations." He made a face at the small tin of concentrates he had dug out of the supply compartment.
 
"We'd do well to be headed west," Raf ventured.
 
"Now you can come in with that on the com again!" Soriki answered with unwonted emphasis. "The sooner I see the old girl standing on her pins in the middle distance, the better I'll feel. You know"—he looked up from his preoccupation with the ration package and gazed out over the city—"this place gives me the shivers. That other town was bad enough. But at least there were people living there. Here's nothing at all—at least nothing I want to see."[99]
 
"What about all the wonders they've promised to show us?" countered Raf.
 
Soriki grinned. "And how much do we understand of their mouth-and-hand talk? Maybe they were promising us wonders, maybe they were offering to take us to where we could have our throats cut more conveniently—for them! I tell you, if I go for a walk with any of these painted faces, I'm going to have at least three of my fingers resting on the grip of my stun gun. And I'd advise you to do the same—if I didn't know that you were already watching these blast-happy harpies out of the corner of your eye. Ha—company. Oh, it's the captain—"
 
The hatch of the globe had opened, and a small party was descending the ladder, conspicuous among them the form and uniform of Captain Hobart. The aliens remained in a cluster at the foot of the ladder while the Terran commander crossed to the flitter.
 
"You"—he pointed to Raf—"are to come along with us."
 
"Why, sir?" "What about me, sir?" The questions from the two at the flitter came together.
 
"I said that one of you had to remain by the machine. Then they said that you, in particular, must come along, Kurbi."
 
"But I'm the pilot—" Raf began and then realized that it was just that fact which had made the aliens attach him to the exploring party. If they believed that the Terran flitter was immobilized when he, and he alone, was not behind its controls, this was just the move they would make. But there they were wrong. Soriki might not be able to repair or service the motor, but in a pinch he could take it up, send it westward, and land it beside the spacer. Each and every man aboard the RS 10 had that much training.
 
Now the com-tech was scowling. He had grasped the significance of that arrangement as quickly as Raf. "How long do I wait for you, sir?" he asked in a voice which had lost its usual good-humored drawl.[100]
 
And at that inquiry Captain Hobart showed signs of irritation. "Your suspicions are not founded on facts," he stated firmly. "These people have displayed no signs of wanting to harm us. And an attitude of distrust at this point might be fatal for future friendly contact. Lablet is sure that they have a highly complex society, probably advanced beyond Terran standards, and that their technical skills will be of vast benefit to us. As it happens we have come at just the right moment in their history, when they are striving to get back on their feet after a disastrous series of wars. It is as if a group of off-world explorers had allied themselves with us after the Burn-Off. We can exchange information which will be of mutual benefit."
 
"If any off-world explorers had set down on Terra after the Burn-Off," observed Soriki softly, "they would have come up against Pax. And just how long would they have lasted?"
 
Hobart had turned away. If he heard that half-whisper, he did not choose to acknowledge it. But the truth in the com-tech's words made an impression on Raf, a crew of aliens who had been misguided enough to seek out and try to establish friendly relations with the officials of Pax would have had a short and most unhappy shrift.
