"NT. NT. NT."

He struggled to his knees, his hands at his head.

"No, by G.o.d! I won't listen to you."

"Thirty-three cleared LR at 12:47."

One tower north! Thirty-three was coming down on him, but he was only glad that the pounding had ceased. It commenced again.

"NT. NT. NT. Special cleared JV at 12:48."

Each rushing towards each other with only a minute's difference in schedule! That was close--too close. But what was it he had in his mind?

Suddenly he screamed. He lurched to his feet and leant against the wall.

He knew now. Joe, with those infused and criminal eyes, had gone to Sally and Sonny--to get even. There could be nothing in the world as important as that. He must get after Joe. He must stop him in time.

"NT. NT. NT."

There was something in his brain about stopping a train in time.

"It only needs you to keep all those people from getting killed."

Somebody had told him that. What did it mean? What had altered here in the tower all at once?

There was no longer any red.

"NT. NT. NT."

"I won't answer."

Where had he put his cap and coat. He needed them. He could go without.

He could kill a beast without. His foot trembled on the first step.

"NT. NT. NT. Why don't you answer? What's wrong. No O. K. Are you burning fuses? Wake up. Send an O. K."

The sounder crashed frantically. It conquered him.

He lurched to the table, touched the key, and stuttered out:

"O. K. NT."

He laughed a little. They were in his block, rushing at each other, and Joe was alone at the house with Sally and the child. O. K.!

He lighted another fuse, flung it from the window, and started with automatic movements for the trap.

Let them crash. Let them splinter, and burn, and die. What was the lot of them compared with Sally and Sonny?

The red glare from the fuse sprang into the room. Tolliver paused, bathed in blood.

He closed his eyes to shut out the heavy waves of it. He saw women like Sally and children like Sonny asleep in a train. It gave him an impression that Sally and Sonny were, indeed, on the train. To keep them safe it would be necessary to r.e.t.a.r.d the special until thirty-three should be on the siding and he could throw that lever that would close the switch and make the line safe. He wavered, taking short steps between the table and the trap. Where were Sally and Sonny? He had to get that clear in his mind.

A bitter cold sprang up the trap. He heard the sobbing of a child.

"Sonny!"

It was becoming clear enough now.

The child crawled up the steps on his hands and knees. Tolliver took him in his arms, straining at him pa.s.sionately.

"What is it, Sonny? Where's mama?"

"Papa, come quick. Come quick."

He kept gasping it out until Tolliver stopped him.

"Joe! Did Joe come?"

The child nodded. He caught his breath.

"Joe broke down the door," he said.

"But mama had the gun," Tolliver said hoa.r.s.ely.

The boy shook his head.

"Mama wouldn't let Sonny play with it. She locked it up in the cupboard.

Joe grabbed mama, and she screamed, and said to run and make you come."

In the tower, partially smothered by the storm, vibrated a shrill cry.

For a moment Tolliver thought his wife's martyrdom had been projected to him by some subtle means. Then he knew it was the anxious voice of thirty-three--the pleading of all those unconscious men and women and little ones. He flung up his arms, releasing the child, and ran to the table where he lighted another fuse, and threw it to the track. He peered from the window, aware of the sobbing refrain of his son.

"Come quick! Come quick! Come quick!"

From far to the south drifted a fainter sibilation, like an echo of thirty-three's whistle. To the north a glow increased. The snowflakes there glistened like descending jewels. It was cutting it too close. It was vicious to crush all that responsibility on the shoulders of one ignorant man, such a man as himself, or Joe. What good would it do him to kill Joe now? What was there left for him to do?

He jotted down thirty-three's orders.

The glow to the north intensified, swung slightly to the left as thirty-three took the siding. But she had to hurry. The special was whistling closer--too close. Thirty-three's locomotive grumbled abreast of him. Something tugged at his coat.

"Papa! Won't you come quick to mama?"

The dark, heavy cars slipped by. The red glow of the fuse was overcome by the white light from the south. The last black Pullman of thirty-three cleared the points. With a gasping breath Tolliver threw the switch lever.

"It's too late now, Sonny," he said to the importunate child.

The tower shook. A hot, white eye flashed by, and a blurred streak of cars. Snow pelted in the window, stinging Tolliver's face. Tolliver closed the window and picked up thirty-three's orders. If he had kept the revolver here he could have prevented Joe's leaving the tower. Why had Sally locked it in the cupboard? At least it was there now. Tolliver found himself thinking of the revolver as an exhausted man forecasts sleep.

Someone ran swiftly up the stairs. It was the engineer of thirty-three, surprised and impatient.
