It took P. Walton four of his five-minute allowance to reach the station platform; and here, for just an instant, he paused while his eyes swept the twinkling switch lights in the yards. Then he raced along the length of the platform, jumped from the upper end to the ground, and lurching a little, up the main line track to where fore-shortened, unclassed little switching engine—the 229—was grunting heavily, and stealing a momentary rest after having sent a string of flats flying down a spur under the tender guidance of a brakeman or two. And as P. Walton ran, he reached into his pocket and drew out Nulty's revolver.

There wasn't much light inside the cab—there was only the lamp over the gauges—but it was light enough to show P. Walton's glittering eyes, fever bright, the deadly white of his face, the deadly smile on his lips, and the deadly weapon in his hand, as he sprang through the gangway.

"Get out!" panted P. Walton coldly.

Neither Dalheen, the fireman, nor Mulligan, fat as a porpoise, on the right-hand side, stood upon the order of their going. Dalheen ducked, and took a flying leap through the left-hand gangway; and Mulligan, with a sort of anxious gasp that seemed as though he wished to convey to P. Walton the fact that he was hurrying all he could, squeezed himself through the right-hand gangway and sat down on the ground.

P. Walton pulled the throttle open with an unscientific jerk.

With a kind of startled scream from the hissing steam, the sparks flying from madly racing drivers as the wheel tires bit into the rails, the old 229, like a frightened thoroughbred at the vicious lash of a yokel driver, reared and plunged wildly forward. The sudden, violent start from inertia pitched P. Walton off his feet across the driver's seat, and smashed his head against the reversing lever that stood notched forward in the segment. He gained his feet again, and, his head swimming a little from the blow, looked behind him.

Yells were coming from half a dozen different directions; forms, racing along with lanterns bobbing up and down, were tearing madly for the upper end of the yard toward him; there was a blur of switch lights, red, white, purple and green—then with a wicked lurch around a curve darkness hid them, and the sweep of the wind, the roar of the pounding drivers deadened all other sounds.

P. Walton smiled—a strange, curious, wistful smile—and sat down in Mulligan's seat. His qualifications for a Brotherhood card had been exhausted when he had pulled the throttle—engine driving was not in P. Walton's line. P. Walton smiled at the air latch, the water glass, the gauges and injectors, whose inner workings were mysteries to him—and clung to the window sill of the cab to keep his seat. He understood the throttle—in a measure—he had ridden up and down the yards in the switchers once or twice during the month that was past—that was all.

Quicker came the bark of the exhaust; quicker the speed. P. Walton's eyes were fixed through the cab glass ahead, following the headlight's glare, that silvered now the rails, and now flung its beams athwart the stubble of a butte as the 229 swung a curve. Around him, about him, was dizzy, lurching chaos, as, like some mad thing, the little switcher reeled drunkenly through the night—now losing her wheel-base with a sickening slew on the circling track, now finding it again with a staggering quiver as she struck the tangent once more.

It was not scientific running—P. Walton never eased her, never helped her—P. Walton was not an engineer. He only knew that he must go fast to make the seven miles in eleven minutes—and he was going fast. And, mocking every formula of dynamics, the little switcher, with no single trailing coach to steady it, swinging, swaying, rocking, held the rails.
