Brent walked to the door. "Will you repeat that order you gave me, in front of the others? No? Then I will!"

As he pulled the door open, Mitchum's fist shot out, smashed into his face and knocked him down.

The trainmaster and the road foreman stood in the open doorway.

"He quit!" screamed Mitchum. "The yellow bastard quit at a time like this! He's a law-breaker and a coward!"

In the slow effort of rising from the floor, through the haze of blood running into his eyes, Bill Brent looked up at the two men. He saw that they understood, but he saw the closed faces of men who did not want to understand, did not want to interfere and hated him for putting them on the spot in the name of justice. He said nothing, rose to his feet and walked out of the building.

Mitchum avoided looking at the others. "Hey, you," he called, jerking his head at the night dispatcher across the room. "Come here.

You've got to take over at once."

With the door closed, he repeated to the boy the story of the Diesel at Fairmount, as he had given it to Brent, and the order to send the Comet through with Engine Number 306, if the boy did not hear from him in half an hour. The boy was in no condition to think, to speak or to understand anything: he kept seeing the blood on the face of Bill Brent, who had been his idol. "Yes, sir," he answered numbly Dave Mitchum departed for Fairmount, announcing to every yardman, switchman and wiper in sight, as he boarded the track motor car that he was going in search of a Diesel for the Comet.

The night dispatcher sat at his desk, watching the clock and the telephone, praying that the telephone would ring and let him hear from Mr. Mitchum. But the half-hour went by in silence, and whet there were only three minutes left, the boy felt a terror he could not explain, except that he did not want to send that order, He turned to the trainmaster and the road foreman, asking hesitantly, "Mr. Mitchum gave me an order before he left, but I wonder whether I ought to send it, because I . . . I don't think it's right. He said—"

The trainmaster turned away; he felt no pity: the boy was about the same age as his brother had been.

The road foreman snapped, "Do just as Mr. Mitchum told you.

You're not supposed to think," and walked out of the room.

The responsibility that James Taggart and Clifton Locey had evaded now rested on the shoulders of a trembling, bewildered boy. He hesitated, then he buttressed his courage with the thought that one did not doubt the good faith and the competence of railroad executives. He did not know that his vision of a railroad and its executives was that of a century ago.

With the conscientious precision of a railroad man, in the moment when the hand of the clock ended the half-hour, he signed his name to the order instructing the Comet to proceed with Engine Number 306, and transmitted the order to Winston Station.

The station agent at Winston shuddered when he looked at the order, but he was not the man to defy authority. He told himself that the tunnel was not, perhaps, as dangerous as he thought. He told himself that the best policy, these days, was not to think.

When he handed their copies of the order to the conductor and the engineer of the Comet, the conductor glanced slowly about the room, from face to face, folded the slip of paper, put it into his pocket and walked out without a word.

The engineer stood looking at the paper for a moment, then threw it down and said, "I'm not going to do it. And if it's come to where this railroad hands out orders like this one, I'm not going to work for it, either. Just list me as having quit."

"But you can't quit!" cried the station agent, "They'll arrest you for it!"

"If they find me," said the engineer, and walked out of the station into the vast darkness of the mountain night.

The engineer from Silver Springs, who had brought in Number 306, was sitting in a corner of the room. He chuckled and said, "He's yellow."

The station agent turned to him. "Will you do it, Joe? Will you take the Comet?"

Joe Scott was drunk. There had been a time when a railroad man, reporting for duty with any sign of intoxication, would have been regarded as a doctor arriving for work with sores of smallpox on his face.

But Joe Scott was a privileged person. Three months ago, he had been fired for an infraction of safety rules, which had caused a major wreck; two weeks ago, he had been reinstated in his job by order of the Unification Board. He was a friend of Fred Kinnan; he protected Kinnan's interests in his union, not against the employers, but against the membership.

"Sure," said Joe Scott. "I'll take the Comet. I'll get her through, if I go fast enough."

The fireman of Number 306 had remained in the cab of his engine.

He looked up uneasily, when they came to switch his engine to the head end of the Comet; he looked up at the red and green lights of the tunnel, hanging in the distance above twenty miles of curves. But he was a placid, amicable fellow, who made a good fireman with no hope of ever rising to engineer; his husky muscles were his only asset.

He felt certain that his superiors knew what they were doing, so he did not venture any questions.

The conductor stood by the rear end of the Comet. He looked at the lights of the tunnel, then at the long chain of the Comet's windows. A few windows were lighted, but most of them showed only the feeble blue glow of night lamps edging the lowered blinds. He thought that he should rouse the passengers and warn them. There had been a time when he had placed the safety of the passengers above his own, not by reason of love for his fellow men, but because that responsibility was part of his job, which he accepted and felt pride in fulfilling. Now, he felt a contemptuous indifference and no desire to save them. They had asked for and accepted Directive 10-289, he thought, they went on living and daily turning away in evasion from the kind of verdicts that the Unification Board was passing on defenseless victims—why shouldn't he now turn away from them? If he saved their lives, not one of them would come forward to defend him when the Unification Board would convict him for disobeying orders, for creating a panic, for delaying Mr. Chalmers. He had no desire to be a martyr for the sake of allowing people safely to indulge in their own irresponsible evil.

When the moment came, he raised his lantern and signaled the engineer to start.

"See?" said Kip Chalmers triumphantly to Lester Tuck, as the wheels under their feet shuddered forward. "Fear is the only practical means to deal with people."

The conductor stepped onto the vestibule of the last car. No one saw him as he went down the steps of the other side, slipped off the train and vanished into the darkness of the mountains.

A switchman stood ready to throw the switch that would send the Comet from the siding onto the main track. He looked at the Comet as it came slowly toward him. It was only a blazing white globe with a beam stretching high above his head, and a jerky thunder trembling through the rail under his feet. He knew that the switch should not be thrown. He thought of the night, ten years ago, when he had risked his life in a flood to save a train from a washout. But he knew that times had changed. In the moment when he threw the switch and saw the headlight jerk sidewise, he knew that he would now hate his job for the rest of his life.

The Comet uncoiled from the siding into a thin, straight line, and went on into the mountains, with the beam of the headlight like an extended arm pointing the way, and the lighted glass curve of the observation lounge ending it off.

Some of the passengers aboard the Comet were awake. As the train started its coiling ascent, they saw the small cluster of Winston's lights at the bottom of the darkness beyond their windows, then the same darkness, but with red and green lights by the hole of a tunnel on the upper edge of the windowpanes. The lights of Winston kept growing smaller, each time they appeared; the black hole of the tunnel kept growing larger. A black veil went streaking past the windows at times, dimming the lights: it was the heavy smoke from the coal-burning engine.
