Matt's first impulse had been to leave his machine and rush to the girl's assistance, but before he could pull his feet from the toe-clips, the horse was past him and careering along on its wild course.

There are times when, in the space of a lightning-flash, a person's mind will deal with every conceivable phase of a situation. It was like that with Matt as the white horse and helpless rider went tearing past him.

Unless something was done to stop the runaway animal, the girl would probably be thrown and perhaps killed. Against what he might do for the girl, Matt, for the fraction of an instant, balanced his duty to the McReadys. Then he used the pedals, turned on the gasoline, and switched on the spark. But instead of going on to Phœnix and the recorder's office, he turned the Comet and raced after the girl.


[CHAPTER XIII.]

MATT WINS—AND LOSES.

Motor Matt had seven horses in the twin-cylinders to pit against that one frantic animal that was slashing along the road toward the canal. There was but one thought in his mind, and that was to spur the seven horses into a speed that could overtake the one before it reached the bridge and the water.

He had been racing for a fortune before, but it was for a human life now. With keen, steady eyes he gaged the chances. The white horse was thundering along in the middle of the road, with the scrap of rein dangling on the left side of the bit. He aimed the Comet to bring up on the left side of the frightened beast.

He was half a minute, perhaps, in coming alongside the horse, and during that brief interval he had a brief glimpse of the thrashing, steel-shod heels. A heart's beat later he was abreast of the girl and saw her white, fear-drawn face looking down at him. In another breath he was close to the horse's head.

The time had come when Matt was to put forth his best effort, and win or lose at a single throw of the die. If the horse got away from him—— But he was not thinking of that; he was thinking how he could best hold the animal and bring him to a stop.
