The man on the second team paused to see them pass. In smoke and dust and with war's own din they cleaved the startled air. And the man who saw the look that had set on Van's hard-chiseled face was aware that unless his car should fail there was nothing on earth he could not catch.
Bostwick had begun to weaken. The pace over sage-brush, rocks, and basins of sand was racking both the car and the nerves that held the wheel. How long such a flight could be continued he dared not guess. Even steel has limitations. To what he was fleeing he could scarcely have told, since the telegraph would send its word throughout the desert-land, and overhaul him finally.
A sickening apprehension assailed him, however, within the minute. One of his cylinders was missing. His trained ear caught at the change of the "tune," and he felt his speed decreasing. He glanced back briefly, where the dusty lump of steel, like a red-hot projectile, thundered in his wake.
He beheld a sudden fan-like flare of dust in the cloud Van was making. He even faintly heard the far report, and a grim joy sprang in his being.
Van had blown out a tire. Striking the high places, crowding on the speed, holding to a straight-away course like a merciless fate, the horseman heard an air cushion go, felt the lurch and lameness of the car, and steadied it back upon its road. He did not retreat by so much as a hair the lever advancing his spark. He did not budge the gas control, but left it still wide open. If all of his tires should blow out together he would not halt his pace. He would drive that car to destruction, or to triumph in the race.
Searle's rejoicing endured but the briefest span. His motor had begun again to splutter, in mechanical death. Then, with a sudden memory, sweat broke out on Bostwick's face. His gasolene was gone! He had thoroughly intended refilling his tank, having barely had a sufficient supply to run him from the claim to camp; and this had been neglected.
His car bumped slowly for a score of yards, then died by the side of the road. He leaped out madly, to assure himself the tank was really dry. He cursed, he raved. It seemed absurd for this big, hot creature to be dead. And meantime, like a whirlwind coming on, Van Buren was crashing down upon him.
"By God!" he cried, "I'll fix you for this!" and a wild thought flashed to his mind—a thought of taking Van Buren's car and fleeing as before.
He leaped in the tonneau and caught up a heavy revolver, stored beneath the seat. He glanced at the cylinder. Four of the cartridges only were unused. He remained inside the "fort" of the car, with the weapon cocked and lowered out of sight.
Charging down like a meteor, melting its very course, Van and the red car came by leaps and plunges. He was shutting off the power gradually, but still rushing up with frightening speed, when Bostwick raised his gun and fired.
