Jan was dressed in the short trousers and coat of the Martian farmer, a knotted rope tied around his waist, a hat on his head to keep off the sun. His skin was dark, colored by dye until it was almost bronze.

"You look fine," Erick said to him. He glanced at Mara. Her black hair was tied in a knot, looped through a hollowed-out yuke bone. Her face was dark, too, dark and lined with colored ceremonial pigment, green and orange stripes across her cheeks. Earrings were strung through her ears.

On her feet were tiny slippers of perruh hide, laced around her ankles, and she wore long translucent Martian trousers with a bright sash tied around her waist. Between her small b.r.e.a.s.t.s a chain of stone beads rested, good-luck charms for the coming marriage.

"All right," Erick said. He, himself, wore the flowing grey robe of a Martian priest, dirty robes that were supposed to remain on him all his life, to be buried around him when he died. "I think we'll get past the guards. There should be heavy morning traffic on the road."

They walked on, the hard sand crunching under their feet. Against the horizon they could see specks moving, other persons going toward the City, farmers and peasants and merchants, bringing their crops and goods to market.

"See the cart!" Mara exclaimed.

They were nearing a narrow road, two ruts worn into the sand. A Martian hufa was pulling the cart, its great sides wet with perspiration, its tongue hanging out. The cart was piled high with bales of cloth, rough country cloth, hand dipped. A bent farmer urged the hufa on.

"And there." She pointed, smiling.

A group of merchants riding small animals were moving along behind the cart, Martians in long robes, their faces hidden by sand masks. On each animal was a pack, carefully tied on with rope. And beyond the merchants, plodding dully along, were peasants and farmers in an endless procession, some riding carts or animals, but mostly on foot.

Mara and Jan and Erick joined the line of people, melting in behind the merchants. No one noticed them; no one looked up or gave any sign. The march continued as before. Neither Jan nor Mara said anything to each other. They walked a little behind Erick, who paced with a certain dignity, a certain bearing becoming his position.

Once he slowed down, pointing up at the sky. "Look," he murmured, in the Martian hill dialect. "See that?"

Two black dots circled lazily. Martian patrol craft, the military on the outlook for any sign of unusual activity. War was almost ready to break out with Terra. Any day, almost any moment.

"We'll be just in time," Erick said. "Tomorrow will be too late. The last ship will have left Mars."

"I hope nothing stops us," Mara said. "I want to get back home when we're through."

Half an hour pa.s.sed. They neared the City, the wall growing as they walked, rising higher and higher until it seemed to blot out the sky itself. A vast wall, a wall of eternal stone that had felt the wind and sun for centuries. A group of Martian soldiers were standing at the entrance, the single pa.s.sage-gate hewn into the rock, leading to the City. As each person went through the soldiers examined him, poking his garments, looking into his load.

Erick tensed. The line had slowed almost to a halt. "It'll be our turn, soon," he murmured. "Be prepared."

"Let's hope no Leiters come around," Jan said. "The soldiers aren't so bad."

Mara was staring up at the wall and the towers beyond. Under their feet the ground trembled, vibrating and shaking. She could see tongues of flame rising from the towers, from the deep underground factories and forges of the City. The air was thick and dense with particles of soot.

Mara rubbed her mouth, coughing.

"Here they come," Erick said softly.

The merchants had been examined and allowed to pa.s.s through the dark gate, the entrance through the wall into the City. They and their silent animals had already disappeared inside. The leader of the group of soldiers was beckoning impatiently to Erick, waving him on.

"Come along!" he said. "Hurry up there, old man."

Erick advanced slowly, his arms wrapped around his body, looking down at the ground.

"Who are you and what's your business here?" the soldier demanded, his hands on his hips, his gun hanging idly at his waist. Most of the soldiers were lounging lazily, leaning against the wall, some even squatting in the shade. Flies crawled on the face of one who had fallen asleep, his gun on the ground beside him.

"My business?" Erick murmured. "I am a village priest."

"Why do you want to enter the City?"

"I must bring these two people before the magistrate to marry them." He indicated Mara and Jan, standing a little behind him. "That is the Law the Leiters have made."

The soldier laughed. He circled around Erick. "What do you have in that bag you carry?"

"Laundry. We stay the night."

"What village are you from?"

"Kranos."

"Kranos?" The soldier looked to a companion. "Ever heard of Kranos?"

"A backward pig sty. I saw it once on a hunting trip."

The leader of the soldiers nodded to Jan and Mara. The two of them advanced, their hands clasped, standing close together. One of the soldiers put his hand on Mara's bare shoulder, turning her around.

"Nice little wife you're getting," he said. "Good and firm-looking." He winked, grinning lewdly.

Jan glanced at him in sullen resentment. The soldiers guffawed. "All right," the leader said to Erick. "You people can pa.s.s."

Erick took a small purse from his robes and gave the soldier a coin.

Then the three of them went into the dark tunnel that was the entrance, pa.s.sing through the wall of stone, into the City beyond.

They were within the City!

"Now," Erick whispered. "Hurry."

Around them the City roared and cracked, the sound of a thousand vents and machines, shaking the stones under their feet. Erick led Mara and Jan into a corner, by a row of brick warehouses. People were everywhere, hurrying back and forth, shouting above the din, merchants, peddlers, soldiers, street women. Erick bent down and opened the case he carried.

From the case he quickly took three small coils of fine metal, intricate meshed wires and vanes worked together into a small cone. Jan took one and Mara took one. Erick put the remaining cone into his robe and snapped the case shut again.

"Now remember, the coils must be buried in such a way that the line runs through the center of the City. We must trisect the main section, where the largest concentration of buildings is. Remember the maps! Watch the alleys and streets carefully. Talk to no one if you can help it. Each of you has enough Martian money to buy your way out of trouble. Watch especially for cut-purses, and for heaven's sake, don't get lost."

Erick broke off. Two black-clad Leiters were coming along the inside of the wall, strolling together with their hands behind their backs. They noticed the three who stood in the corner by the warehouses and stopped.

"Go," Erick muttered. "And be back here at sundown." He smiled grimly.

"Or never come back."

Each went off a different way, walking quickly without looking back. The Leiters watched them go. "The little bride was quite lovely," one Leiter said. "Those hill people have the stamp of n.o.bility in their blood, from the old times."

"A very lucky young peasant to possess her," the other said. They went on. Erick looked after them, still smiling a little. Then he joined the surging ma.s.s of people that milled eternally through the streets of the City.

At dusk they met outside the gate. The sun was soon to set, and the air had turned thin and frigid. It cut through their clothing like knives.

Mara huddled against Jan, trembling and rubbing her bare arms.
