A fusilade of shots rang out. Flashes cut the black. The Butcher's two companions, evidently driving the engineer and fireman before them, were coming on the run along the trackside from the cab. The Hawk retreated back a step, and closed the car door. He heard the men rush past outside. The fusilade seemed to redouble in intensity; and now, added to it, were shouts and yells from the rear of the train itself, and—if he were not mistaken—answering shots.

His hand on the doorknob, he stood waiting tensely. With the Butcher on guard out there in front, it would have been equivalent to suicide to have opened the door again until he knew the other was back in the cab—against the background of the lighted interior he would have made a most excellent mark for the Butcher!

His eyes swept past the huddled form of the young messenger in the chair, and fixed speculatively on the safe. He nodded suddenly, grimly. Twenty thousand dollars! Well, he wasn't beaten yet—not till he threw down his own hand of his own accord—not till he lost sight of the safe for keeps!

Over the shouts and revolver shots came the sharp, vicious hiss of the air-hose, as it was uncoupled; and then, with a violent jerk, the car started forward, as the Butcher evidently whipped the throttle open. And, coincidently, there was a smash upon the rear door—and the Hawk opened the forward door and slipped out again.

A din infernal was in his ears. Like a maddened thing under the Butcher's unscientific spur, the big ten-wheeler was coughing the sparks heavenward in a volleying stream, while the huge drivers raced like pinwheels in another shower of sparks as the tires sought to bite and hold. And now the rear door of the car crashed inward; the shots came fast as a gatling, and shouts, screams and yells added their quota to the uproar.

The Hawk, crouched by the door, moved suddenly to one side, as he caught the dull, ominous spat of a bullet against one of the panels. The train crew and those of the passengers who were armed were, very obviously, keeping up a running fight from the stalled section of the train, and pumping their bul-lets through the broken rear door and up the aisle of the express car as long as they could hold the range; and, from within, he could distinguish the duller, muffled reports of the Butcher's confederates firing in return, preventing any attempt being made to rush the rear of the car.

And then the sounds began to recede and die away. The men inside the car ceased firing, and he could hear them now moving the safe out from the side of the car. It seemed as though a very long interval of time had been consumed in the hold-up; but in reality he knew it had been little more than a matter of seconds—the time it had taken the two men to run the length of the car, uncouple it, and leap on the rear end. The fight afterwards could hardly count, for once the express car began to pull away the thing was done.

They were moving fast now, and with every instant the speed was increasing. The Hawk clutched at the handrail, and lowered himself to the iron foot-rung which, on the express car, served in lieu of steps. Here, having chosen the opposite side to that of the Butcher at the throttle in the cab, he ran no risk of being observed. This “five-mile crossing,” wherever it was, promised to concern him a great deal more than he had anticipated! He leaned out, and clung there, staring ahead.

The big ten-wheeler was swaying and staggering like a drunken thing; the rush of the wind whipped at his face; a deafening roar sang in his ears. The Fast Mail usually ran fast; but the Butcher was running like a dare-devil, and the bark of the exhaust had quickened now into a single full-toned note deep as thunder.

With a sort of grim placidity, the Hawk clung to the lurching rail. Far ahead along the right of way, a shaft of light riven through walls of blackness, played the headlight. Shadowy objects, trees that loomed up for an instant and were gone, showed on the edge of the wavering ray. They tore through a rock cut, and, in the confined space and in the fraction of a second it took to traverse it, the roar was metamorphosed into an explosion. And then suddenly, as though by magic, the headlight shot off at a tangent, and the glistening lines of steel, that were always converging but never meeting, were gone, and the ray fell full upon a densely wooded tract where leaves and foliage became a soft and wonderful shade of green under the artificial light. The Hawk braced himself—and just in time. The ten-wheeler, unchecked, swung the curve with a mighty lurch, off drivers fairly lifted from the rails. She seemed to hang there hesitantly for a breathless instant, then with a crunch, staggering, settled back and struck into her stride again.
