There were perhaps a half-dozen men with rifles and a dozen or so with six-shooters, all pumping away at it as fast as they could. The buckboard was struck many times. One horse was hit, but only slightly—not enough to interfere with, but rather to encourage his speed. Billy fastened his eyes on the spot whence the first bullet had sped. Suddenly he threw his rifle to his shoulder.

Crack! it spoke, strangely flat out there in the open against the fuller reports of the other pieces.

The bullets which undershot kicked up little puffs of dust, like grasshoppers jumping, while those that passed above, ricochetted finally from rocks and went singing away into the distance. It was a wonder, with so large a mark, that neither the man nor the horses were hit. It must be remembered, however, that the marksmen were more or less drunk, and that Billy's speed was by now something tremendous.

Crack! went his Winchester again.

At the end of the straight road was, as has perhaps been mentioned, a turn of considerable sharpness, flanked by bold cliff-like rocks. In the best of circumstances, this bit of road requires careful driving. With a runaway four and a light buckboard, a smash up was inevitable. The hidden assailants and spectators of the strange duel realized this suddenly. In the interest of the approaching catastrophe, the fusillade ceased as abruptly as it had begun. Billy maintained his first attitude, one knee on the seat, the other foot braced against the floor, keenly expectant. The silence became breathless, and one or two men leaned forward the better to see.

"Crack!" spoke Billy's rifle for the third time. The man who had fired the first shot pitched suddenly forward from behind his sheltering corner, and lay still.

With one swift motion the scout dropped his Winchester in the seat, grasped the four reins, and threw his enormous weight against the bits. The grays had been ranch-bred. They bunched their feet, hunched their backs, and in three heavy buck jumps had slowed down from a breakneck run to a lumbering gallop. Billy Knapp gave vent to the wild shrill war cry of his foster parents, the Oglallah Sioux, and jogged calmly out of sight around the bend of the road.

A great crowd pressed about Tony Houston, prone on the ground. They discovered that the ball had passed through the point of the shoulder, not a dangerous place in itself, but resulting in a serious wound because of the smashing power of the express rifle.

"Damn fine shooting!" they said, looking at each other with admiration. "Damn fine."

They began to feel a little more kindly toward Billy on account of this evidence of his skill. They set about bandaging the wounded man.
