Kevin pointed down the long winding street. "We go down to the foot of this street, turn right into Carhill Boulevard, head down the main drive toward the bridge. The Earther city is on the other side of the river."

"You better be right."

They made it at a fairly good clip through the sleepy Enclave, pa.s.sing rapidly through the old, dry, dusty streets. Finally they came to the end of the street and rounded the corner onto Carhill Boulevard.

The first thing Alan saw was the majestic floating curve of the bridge.

Then he saw the Earther city, a towering pile of metal and masonry that seemed to be leaping up into the sky ahead of them, completely filling the view.

Alan pointed to the bridge-mouth. "That's where we go across, isn't it?"

But Quantrell hung back. He stopped in his tracks, staring dangle-jawed at the immense city facing them.

"There it is," he said quietly.

"Sure. Let's go, eh?" Alan felt a sudden burst of impatience and started heading toward the approach to the bridge.

But after three or four paces he realized Quantrell was not with him. He turned and saw the other s.p.a.ceman still rooted to the ground, gazing up at the vast Earther city as if in narcoshock.

"It's big," Quantrell murmured. "_Too_ big."

"_Kevin!_ What's wrong?"

"Leave him alone," Rat whispered. "I have a hunch he won't be going with you."

Alan watched in astonishment as Quantrell took two steps hesitantly backward away from the bridge, then a third. There was a strange, almost thunderstruck expression on Kevin's face.

Then he broke out of it. He shook his head.

"We aren't really going across--huh, Donnell?" He gave a brittle little laugh.

"Of course we are!" Alan looked around nervously, hoping no one from the _Valhalla_ had spotted him in all this time. Puzzled at Quantrell's sudden hesitation after his earlier c.o.c.kiness, Alan took a couple of shuffling steps toward the bridge, slowly, keeping his eyes on the other starman.

"I can't go with you," Kevin finally managed to say. His face was flushed and strained-looking. He was staring upward at the seemingly topless towers of the city. "It's too big for me." He choked back a half-whimper. "The trouble with me is--the--trouble--with--me--is----"

Quantrell lowered his head and met Alan's stare. "I'm afraid, Donnell.

Stinking sweaty afraid. The city's too big."

Red-faced, he turned and walked away, back up the street.

Alan silently watched him go.

"Imagine that. Afraid!"

"It's a big place," Rat warned. "Don't you feel the same way? Just a little?"

"I feel perfectly calm," Alan said in utter sincerity. "I know why I'm going over there, and I'm anxious to get moving. I'm not running away, the way Steve was. I'm going to the Earther city to find my brother and to find Cavour's drive, and to bring them both back here!"

"That's a tall order, Alan."

"I'll do it."

Alan reached the approach to the bridge in a few more brisk steps and paused there. The noonday sun turned the long arch of the bridge into a golden ribbon in the sky. A glowing sign indicated the pedestrian walkway. Above that, shining teardrop autos whirred by, leaving faint trails of exhaust. Alan followed the arrows and soon found himself on the bridge, heading for the city.

He glanced back a last time. There was no sign of Kevin. The Starmen's Enclave seemed utterly quiet, almost dead.

Then he turned and kept his gaze forward. The Earther city was waiting for him.

_Chapter Five_

He reached the end of the walkway and paused, a little stunned, staring at the incredible immensity of the city spread out before him.

"It's a big place," he said. "I've never been in a city this big."

"You were born here," Rat reminded him.

Alan laughed. "But I only stayed here a week or two at most. And that was three hundred years ago. The city's probably twice as big now as it was then. It----"

"Hey, you! Move on!" a harsh voice from behind snapped suddenly.

"What's that?"

Alan whirled and saw a tall, bored-looking man in a silver-gray uniform with gleaming luminescent bands across the sleeves, standing on a raised platform above the road.

"You can't just stand here and block the walkway," the tall man said.

His words were heavily accented, thickly guttural; Alan had a little trouble understanding them. The ship's language never changed; that of Earth kept constantly evolving. "Get back in the Enclave where you belong, or get moving, but don't stand here or I'll punch your ticket for you."

Alan took a couple of steps forward. "Just hold on a minute. Who----"

"He's a policeman, Alan," Rat said softly. "Don't make trouble. Do as he says."

Throttling his sudden anger, Alan nodded curtly at the officer and stepped off the walkway. He was an outsider here, and knew he couldn't expect the sort of warm fellowship that existed aboard the ship.

This was a city. A crowded, uncomfortable Earther city. These were the people who were left behind, who never saw the stars in naked glory.

They weren't going to be particularly polite.

Alan found himself at an intersection, and wondered where he was to begin. He had some vague idea of finding Steve in this city as easily as he might aboard ship--just check the A Deck roster, then the B Deck, and so on until he found him. But cities weren't quite that neatly organized, Alan realized.

A long broad street ran parallel to the river. It didn't seem very promising: lined with office buildings and warehouses. At right angles to it, though, stretching out in front of him, was a colorful, crowded avenue that appeared to be a major artery of the city. He glanced tentatively in both directions, waited till a lull came in the steady procession of tiny bullet-shaped automobiles flashing by, and hastily jogged across the waterfront street and started down the avenue.

Maybe there was some kind of register of population at the City Hall.

If Steve still lived in this city, he could look him up that way. If not----

Facing him were two rows of immense buildings, one on each side of the street. Above every three blocks there was a lacy aerial pa.s.sageway connecting a building on one side of the street with one on the other, high above the ground. Alan looked up and saw black dots--they looked like ants, but they were people--making their way across the flexi-bridges at dizzying alt.i.tudes.

The streets were crowded. Busy stern-faced people raced madly from one place to the next; Alan was accustomed to the more orderly and peaceful life of a starship, and found himself getting jostled by pa.s.sersby from both directions.
