While the engines were yet two hundred yards apart, the duel began, shot answering shot, the sharp staccato reports punctuating the thunder of wheels and the clamour of steam.

Then the ground trembled and rocked; a roar as of heavy ordnance developed with the abruptness of an explosion. The two engines passed each other, the men firing the while, emptying their revolvers, shattering wood, shivering glass, the bullets clanging against the metal work as they struck and struck and struck. The men leaned from the cabs towards each other, frantic with excitement, shouting curses, the engines rocking, the steam roaring; confusion whirling in the scene like the whirl of a witch's dance, the white clouds of steam, the black eddies from the smokestack, the blue wreaths from the hot mouths of revolvers, swirling together in a blinding maze of vapour, spinning around them, dazing them, dizzying them, while the head rang with hideous clamour and the body twitched and trembled with the leap and jar of the tumult of machinery.

Roaring, clamouring, reeking with the smell of powder and hot oil, spitting death, resistless, huge, furious, an abrupt vision of chaos, faces, rage-distorted, peering through smoke, hands gripping outward from sudden darkness, prehensile, malevolent; terrible as thunder, swift as lightning, the two engines met and passed.

“He's hit,” cried Delaney. “I know I hit him. He can't go far now. After him again. He won't dare go through Bonneville.”

It was true. Dyke had stood between cab and tender throughout all the duel, exposed, reckless, thinking only of attack and not of defence, and a bullet from one of the pistols had grazed his hip. How serious was the wound he did not know, but he had no thought of giving up. He tore back through the depot at Guadalajara in a storm of bullets, and, clinging to the broken window ledge of his cab, was carried towards Bonneville, on over the Long Trestle and Broderson Creek and through the open country between the two ranches of Los Muertos and Quien Sabe.

But to go on to Bonneville meant certain death. Before, as well as behind him, the roads were now blocked. Once more he thought of the mountains. He resolved to abandon the engine and make another final attempt to get into the shelter of the hills in the northernmost corner of Quien Sabe. He set his teeth. He would not give in. There was one more fight left in him yet. Now to try the final hope.

He slowed the engine down, and, reloading his revolver, jumped from the platform to the road. He looked about him, listening. All around him widened an ocean of wheat. There was no one in sight.

The released engine, alone, unattended, drew slowly away from him, jolting ponderously over the rail joints. As he watched it go, a certain indefinite sense of abandonment, even in that moment, came over Dyke. His last friend, that also had been his first, was leaving him. He remembered that day, long ago, when he had opened the throttle of his first machine. To-day, it was leaving him alone, his last friend turning against him. Slowly it was going back towards Bonneville, to the shops of the Railroad, the camp of the enemy, that enemy that had ruined him and wrecked him. For the last time in his life, he had been the engineer. Now, once more, he became the highwayman, the outlaw against whom all hands were raised, the fugitive skulking in the mountains, listening for the cry of dogs.

But he would not give in. They had not broken him yet. Never, while he could fight, would he allow S. Behrman the triumph of his capture.

He found his wound was not bad. He plunged into the wheat on Quien Sabe, making northward for a division house that rose with its surrounding trees out of the wheat like an island. He reached it, the blood squelching in his shoes. But the sight of two men, Portuguese farm-hands, staring at him from an angle of the barn, abruptly roused him to action. He sprang forward with peremptory commands, demanding a horse.
