"There's a good boy!" said Judith coolly. "Buck a little for the lady, Prince!"

Slowly the great muscles of Prince's leg and shoulder and flank corded. The trembling passed; he was like a horse carven in bluish granite. He shook his head a little. Judith, her hand tightening upon the reins, held his head well up, the severe bit thwarting the attempt to get his nose down between his forelegs.

Then suddenly, without sign of warning, the horse whirled, leaping far out to the left, striking with hard hoofs bunched, gathering himself as he landed, swerving with the quickness of light, plunging again to the right. And again he stood still. Judith, sitting securely on his rebellious back, laughed. Her laughter, cool and unafraid, sent a strange little thrill through Bud Lee—who, with fear in his heart, was watching her.

"Look out for him now!" he called warningly.

In truth the Prince had not yet begun. He had tried a trick which would have unseated any but one who rode well. He knew that he had to do with something more than a rank amateur.

Now he plunged toward the corral, his purpose plain, the one desire in his heart to crush his rider against the high fence. But Judith's spurs answered him, and the bit, savage in his jaws, brought him about, whirling, sidling, striking, bucking as only a strong, fearless, devil-hearted horse knows how to buck. He doubled up under her; he rose and fell in a quick series of short jumps which tore and jerked at her body, which strove to tear her knees away from his sides and break the grip of her hand on the reins. But it seemed to the men watching that the girl knew before the horse which way he would jump, that she knew how to sway her body with his so that she and he were not two separate beings but just one, moving together in some mad devil's dance. The Prince, in the midst of the vicious bucking, tried to rear, seeking to throw himself backward; a quick, sharp blow of a loaded quirt between his ears brought his forefeet back to earth.

"Can she ride!" whispered Bud Lee. "I want to know!"

Again the maddened Prince reared and again she brought him to earth. Again he resumed the terribly tearing series of short, sharp bucks. And still, her hair tumbling, blown about her shoulders, she rode him.

Old Carson was muttering and pulling at his lip nervously. Out of the corner of his mouth in a voice that was almost a whimper, he kept cursing and saying to Ward Hannon: "You skunk! You ornery skunk! Hunt your hole after this!"

Suddenly, with a quick, concerted action of spur, whip, and rein, Judith swung the Prince about so that he was headed for the open valley, running toward the west, giving him his head only a little, driving him. He broke into a thundering run, snorting as, with mane and tail flying, he dashed through the men who fell away from his furious rush. And as he ran, Judith spurred him so that his only thought lay in running away from the menace upon his back.
