A gust of wind sprang through the trap door. The yellow slips fluttered.

He ran to the trap. He heard the lower door bang shut. Someone was on the stairs, climbing with difficulty, breathing hard. A hat, crusted with snow, appeared. There came slowly into the light Joe's face, ugly and inflamed; the eyes restless with a grave indecision.

Tolliver's first elation died in new uncertainty.

"Where you been?" he demanded fiercely.

Joe struggled higher until he sat on the flooring, his legs dangling through the trap. He laughed in an ugly and unnatural note; and Tolliver saw that there was more than drink, more than sleeplessness, recorded in his scarlet face. Hatred was there. It escaped, too, from the streaked eyes that looked at Tolliver as if through a veil. He spoke thickly.

"Don't you wish you knew?"

Tolliver stooped, grasping the man's shoulders. In each fist he clenched bunches of wet cloth. In a sort of desperation he commenced to shake the bundled figure.

"You tell me where you been----"

"NT. NT. NT."

Joe leered.

"Joe! You got to tell me where you been."

The pounding took Tolliver's strength. He crouched lower in an effort to avoid it, but each blow struck as hard as before, forcing into his brain word after word that he pa.s.sionately resented. Places, hours, minutes--the details of this vital pa.s.sage of two trains in the unfriendly night.

"Switch whichever arrives first, and hold until the other is through."

It was difficult to understand clearly, because Joe's laughter persisted, crashing against Tolliver's brain as brutally as the sounder.

"You got to tell me if you been bothering Sally."

The hatred and the cunning of the mottled face grew.

"Why don't you ask Sally?"

Slowly Tolliver let the damp cloth slip from his fingers. He straightened, facing more definitely that abominable choice. He glanced at his cap and overcoat. The lazy clock hands reminded him that he had remained in the tower nearly half an hour beyond his time. Joe was right. It was clear he could satisfy himself only by going home and asking Sally.

"Get up," he directed. "I guess you got sense enough to know you're on duty."

Joe struggled to his feet and lurched to the table. Tolliver wondered at the indecision in the other's eyes, which was more apparent. Joe fumbled aimlessly with the yellow slips. Tolliver's fingers, outstretched toward his coat, hesitated, as if groping for an object that must necessarily elude them.

"Special!" Joe mumbled. "And--h.e.l.l! Ain't thirty-three through yet?"

He swayed, s.n.a.t.c.hing at the edge of the table.

Tolliver lowered his hands. The division superintendent had pounded out something about fuses. What had it been exactly? "Keep fuses burning."

With angry gestures he took his coat and cap down, and put them on while he repeated all the instructions that had been forced into his brain with the effect of a physical violence. At the table Joe continued to fumble aimlessly.

"Ain't you listening?" Tolliver blurted out.

"Huh?"

"Why don't you light a fuse?"

It was quite obvious that Joe had heard nothing.

"Fuse!" Joe repeated.

He stooped to a box beneath the table. He appeared to lose his balance.

He sat on the floor with his back against the wall, his head drooping.

"What about fuse?" he murmured.

His eyes closed.

Tolliver pressed the backs of his hands against his face. If only his suspense might force refreshing tears as Sonny cried away his infant agonies!

Numerous people asleep in that long Pullman train, and the special thundering down! Sally and Sonny a half mile away in the lonely house!

And that drink-inspired creature on the floor--what was he capable of in relation to those unknown, helpless travelers? But what was he capable of; what had he, perhaps, been capable of towards those two known ones that Tolliver loved better than all the world?

Tolliver shuddered. As long as Joe was here Sally and Sonny would not be troubled. But where had Joe been just now? How had Sally and Sonny fared while Tolliver had waited for that stumbling step on the stairs? He had to know that, yet how could he? For he couldn't leave Joe to care for all those lives on the special and thirty-three.

He removed his coat and cap, and replaced them on the hook. He took a fuse from the box and lighted it. He raised the window and threw the fuse to the track beneath. It sputtered and burst into a flame, ruddy, gorgeous, immense. It etched from the night distant fences and trees. It bent the sparkling rails until they seemed to touch at the terminals of crimson vistas. If in the storm the locomotive drivers should miss the switch lamps, set against them, they couldn't neglect this bland banner of danger, flung across the night.

When Tolliver closed the window he noticed that the ruddy glow filled the room, rendering sickly and powerless the yellow lamp wicks. And Tolliver clutched the table edge, for in this singular and penetrating illumination he saw that Joe imitated the details of sleep; that beneath half-closed lids, lurked a fanatical wakefulness, and final resolution where, on entering the tower, he had exposed only indecision.

While Tolliver stared Joe abandoned his masquerade. Wide-eyed, he got lightly to his feet and started for the trap.

Instinctively, Tolliver's hand started for the drawer where customarily the revolver was kept. Then he remembered, and was sorry he had sent the revolver to Sally. For it was clear that the poison in Joe's brain was sending him to the house while Tolliver was chained to the tower. He would have shot, he would have killed, to have kept the man here. He would do what he could with his hands.

"Where you going?" he asked hoa.r.s.ely.

Joe laughed happily.

"To keep Sally company while you look after the special and thirty-three."

Tolliver advanced cautiously, watching for a chance. When he spoke his voice had the appealing quality of a child's.

"It's my time off. If I do your work you got to stay at least."

Joe laughed again.

"No. It only needs you to keep all those people from getting killed."

Tolliver sprang then, but Joe avoided the heavier, clumsier man. He grasped a chair, swinging it over his head.

"I'll teach you," he grunted, "to kick me out like dirt. I'll teach you and Sally."

With violent strength he brought the chair down. Tolliver got his hands up, but the light chair crashed them aside and splintered on his head.

He fell to his knees, reaching out blindly. He swayed lower until he lay stretched on the floor, dimly aware of Joe's descending steps, of the slamming of the lower door, at last of a vicious pounding at his bruised brain.
