"Hell," said Herb, "it takes all kinds of people to make a universe."

The Engineer led them through an air lock which opened from the room into a mighty corridor… a corridor that stretched away for inconceivable distances, a vast place that held a brooding sense of empty space.

The suits functioned perfectly. Gravity and pressure were normal and the suits themselves were far more comfortable than the spacesuits used back in the solar system.

Slowly they trudged down the hall behind the Engineer.

"How long did it take to build this city?" asked Gary.

"Many years," said the Engineer. "Since we came here."

"Came here?" asked Gary. "Then this isn't your native planet?"

"No," said the Engineer, but he did not offer to explain.

"Say," said Herb, "you didn't ask our names. You don't know who we are."

Gary thought he detected a faint semblance of dry humor in the answer of the Engineer.

"Names," he said. "You mean personal designations? I know who you are without knowing names."

"Maybe," said Herb, "but we can't read thoughts like you can. We got to have names." He trotted along at the heels of the Engineer. "Don't you fellows have names?" he asked.

"We are designated by numbers," said the Engineer. "Purely as a matter of record. The individual doesn't count so much here as he does where you came from."

"Numbers," said Herb. "Just like a penitentiary."

"If it is necessary for you to designate me," said the Engineer, "my number is 1824. I should have told you sooner. I am sorry I forgot."

They halted before a massive door and the Engineer sounded a high-pitched thought-wave that beat fantastically against their minds. The great door slid back into the wall and they walked into a room that swept away in lofty reaches of vast distances, with a high-vaulted ceiling that formed a sky-like cup above them.

The room was utterly empty of any sort of furniture. Just empty space that stretched away to the dim, far walls of soaring white. But in its center was a circular elevation of that same white stone, a dais-like structure that reared ten feet or more above the white-paved floor.

Upon the dais stood several of the Engineers and around them were grouped queer, misshapen things, nightmares snatched from some book of olden horrors, monstrosities that made Gary's blood run cold as be gazed upon them.

He felt Caroline's fingers closing on his arm. "Gary," her whisper was thin and weak, "what are they?"

"Those are the ones that we have called," said the Engineer. "The ones who have come so far to help us in our fight."

"They look like something a man would want to step on," said Herb, and there was a horrible loathing in his words.

Gary stared at them, fascinated by their very repulsiveness. Lords of the universe, he thought. These are the things that represent the cream of the universe's intelligence. These things that looked, as Herb had said, like something you would want to step on.

The Engineer was walking straight ahead, toward the wide, shallow steps that led up to the dais.

"Come on," rumbled Kingsley. "Maybe we look as bad to them."

They crossed the hall and tramped up the steps. The Engineer crossed to the other Engineers.

"These," he said, "are the ones who have come from the outer planet of the solar system we have watched so many years."

The Engineers looked at them. So did the other things. Gary felt his skin crawling under the scrutiny.

"They are welcome," came the thought-wave of one of the Engineers. "You have told them how glad we are to have them here?"

"I have told them," declared Engineer 1824.

There were chairs for the Earthlings. One of the Engineers waved an invitation to them and they sat down.

Gary looked around. They were the only ones who had chairs. The Engineers, apparently tireless, remained standing. Some of the other things stood, too. One of them stood on a single leg with his second leg tucked tight against his body — like a dreaming stork — except that he didn't look like a stork. Gary tried to classify him. He wasn't a bird or a reptile or a mammal. He wasn't anything a human being had ever imagined. Long, skinny legs, great bloated belly, head with unkempt hair falling over brooding, dead-fish eyes.

One of the Engineers began to speak.

"We have gathered here," said the thought-waves, "to consider ways and means of meeting one of the greatest dangers…"

Just like a political speaker back on Earth, thought Gary. He tried to make out which one of the Engineers was talking, but there was no facial expression, no movement of any sort which would determine which one of them the speaker might be. He tried to pick out Engineer 1824, but all the Engineers looked exactly alike.

The talk rumbled on, a smooth roll of thought explaining the situation that they faced, the many problems it presented, the need of acting at once.

Gary studied the other things about them, the loathsome, unnatural things that had been brought here from the unguessed depths of the universe. He shuddered and felt cold beads of sweat break out upon his body as he looked at them.

Several of them were immersed in tanks filled with liquids. One tank boiled and steamed as if with violent chemical action; another was cloudy and dirty-looking; another was clear as water and in it lurked a thing that struck stark terror into Gary's soul. Another was confined in a huge glass sphere through which shifted and swirled a poisonous-appearing atmosphere. Gary felt cold fingers touch his spine as he watched the sphere and suddenly was thankful for the shifting mists within it, for through them he had caught sight of something that he was certain would have shattered one's mind to look upon without the shielding swirl of fog within the glass.

In a small glass cage set upon a pedestal of stone were several writhing, grub-like things that palpitated disgustingly. Squatting on its haunches directly across from Gary was a monstrosity with mottled skin and drooling mouth, with narrow, slitted eyes and slimy features. He fastened his pinpoint gaze upon the Earthman and Gary quickly looked away.

Nothing resembled mankind, nothing except the Engineers. Here were things that were terrible caricatures of the loathsome forms of Earth life, other beings that bore not even the most remote resemblance to anything that mankind had ever seen or imagined.

Was this a fair sample of the intelligence the universe contained? Did he and Kingsley and Caroline appear as disgusting, as fearsome in the eyes as these other denizens of the universe as they appeared to his?

He shot a quick glance at Caroline. She was listening intently, her chin cupped in one hand, her eyes upon the Engineers. Just as well that way, he thought. She didn't see these other things.

The Engineer had stopped talking and silence fell upon the room. Then a new impulse of thought beat against Gary's brain, thought that seemed cold and cruel, thought that was entirely mechanistic and consciousless. He glanced swiftly around, trying to find who was speaking. It must, he decided, be the thing in the glass sphere. He could not understand the thought, grasped just vague impressions of atomic structures and mathematics that seemed to represent enormous pressure used to control surging energy.

The Engineer was talking again.

"Such a solution," he was saying, "would be possible on a planet such as yours, where an atmosphere many miles in depth, composed of heavy gases, creates the pressures that you speak of. While we can create such pressures artificially, we could not create or maintain them outside the laboratory."

"What the hell," asked Herb, "are they arguing about?"

"Shut up," hissed Gary, and the photographer lapsed into shamefaced silence.

The cold, cruel thought was arguing, trying to explain a point that Gary could only guess at. He looked at Caroline, wondering if she understood. Her face was twisted into tiny lines of concentration.
