The calm voice was proceeding: "Old sport, you and me are going to stage a sure enough scrap right here and now. Speaking personal, I'd like to take off the rope and go at you man to man with no saddle to help me out. But if I did that I wouldn't have a ghost of a show. I'll saddle you, right enough, but I'll ride you without spurs, and I'll put a straight bit in your mouth—damn the Mexican soul of Cordova, I see where he's sawed your mouth pretty near in two with his Spanish contraptions! Without a quirt or spurs or a curb to choke you down, you and me'll put on a square fight, so help me God! Because I think I can beat you, old hoss. Here goes!"

The stallion listened to the soothing murmur, listened and waited, and sure enough he had not long to stay in expectation. For Perris went to the hole behind the rock and presently returned carrying that flapping, creaking instrument of torture—a saddle.

To all that followed—the blind-folding, the bridling, the jerk which urged him to his feet, the saddling,—Alcatraz submitted with the most perfect docility. He understood now that he was to have a chance to fight for his liberty on terms of equality and his confidence grew. In the old days that consummate horseman, Manuel Cordova, had only been able to keep his seat by underfeeding Alcatraz to the point of exhaustion but now, from withers to fetlock joint, the chestnut was conscious of a mighty harmony of muscles and reserves of energy. The wiles which he had learned in many a struggle with the Mexican were not forgotten and the tricks which had so often nearly unseated the old master could now be executed with threefold energy. In the meantime he waited quietly, assuming an air of the most perfect meekness, with the toe of one hind foot pointed so that he sagged wearily on that side, and with his head lowered in all the appearance of mild subjection.

The cinches bit deep into his flesh. He tasted that horror of iron in his mouth, with this great distinction: that whereas the bits of Manuel Cordova had been heavy instruments of torture this was a light thing, smooth and straight and without the wheel of spikes. The crisis was coming. He felt the weight of the rider fall on the left stirrup, the reins were gathered, then Perris swung lightly into the saddle and leaning, snatched the blindfold from the eyes of the stallion.

One instant Alcatraz waited for the sting of the spurs, the resounding crack of the heavy quirt, the voice of the rider raised in curses; but all was silence. The very feel of the man in the saddle was different, not so much in poundage as in a certain exquisite balance which he maintained but the pause lasted no longer than a second after the welcome daylight flashed on the eyes of Alcatraz. Fear was a spur to him, fear of the unknown. He would have veritably welcomed the brutalities of Cordova simply because they were familiar—but this silent and clinging burden? He flung himself high in the air, snapped up his back, shook himself in mid-leap, and landed with every leg stiff. But a violence which would have hurled another man to the ground left Perris laughing. And were beasts understood, that laughter was a shameful mockery!

Alcatraz thrust out his head. In vain Perris tugged at the reins. The lack of curb gave him no pry on the jaw of the chestnut and sheer strength against strength he was a child on a giant. The strips of leather burned through his fingers and the first great point of the battle was decided in favor of the horse: he had the bit in his teeth. It was a vital advantage for, as every one knows who has struggled with a pitching horse, it cannot buck with abandon while its chin is tucked back against its breast; only when the head is stretched out and the nose close to the ground can a bucking horse double back and forth to the full of his agility, twisting and turning and snapping as an "educated" bucker knows how.

And Alcatraz knew, none so well! The deep exclamation of dismay from the rider was sweetest music to his malicious ears, and, in sheer joy of action, he rushed down the hollow at full speed, bucking "straight" and with never a trick attempted, but when the first ecstasy cleared from his brain he found that Perris was still with him, riding light as a creature of mist rather than a solid mass of bone and muscle—in place of jerking and straining and wrenching, in place of plying the quirt or clinging with the tearing spurs, he was riding "straight up" and obeying every rule of that unwritten code which prescribes the manner in which a gentleman cowpuncher shall combat with his horse for superiority. Again that thrill of terror of the unknown passed through the stallion; could this apparently weaponless enemy cling to him in spite of his best efforts? He would see, and that very shortly. Without going through the intermediate stages by which the usual educated bronco rises to a climax of his efforts, Alcatraz began at once that most dreaded of all forms of bucking—sun-fishing. The wooded hills were close now and the ground beneath him was firm underfoot assuring him full use of all his agility and strength. His motion was like that of a breaking comber. First he hurled himself into the air, then pitched sharply down and landed on one stiffened foreleg—the jar being followed by the deadly whiplash snap to the side as he slumped over. Then again driven into the air by the impulse of those powerful hind legs, he landed on the alternate foreleg and snapped his rider in the opposite direction—a blow on the base of the brain and another immediately following on the side.

Underfed mustangs have killed men by this maneuver, repeated without end. Alcatraz was no starveling mongrel, but to the fierceness of a wild horse and the tireless durability of a mustang he united the subtlety which he had gained in his long battle with the Mexican and above all this, his was the pride of one who had already conquered man. His fierce assault began to produce results.

He saw Red Perris sway drunkenly at every shock; his head seemed to swing on a pivot from side to side under that fearful jolting—his mouth was ajar, his eyes staring, a fearful mask of a face; yet he clung in place. When he was stunned, instinct still kept his feet in the stirrups and taught him to give lightly to every jar. He fought hard but in time even Red Perris must collapse.

But could the attack be sustained indefinitely? Grim as were results of sun-fishing on the rider, they were hardly less vitiating for the horse. The forelegs of Alcatraz began to grow numb below the shoulder; his knees bowed and refused to give the shock its primal snap; to the very withers he was an increasing ache. He must vary the attack. As soon as that idea came, he reared and flung himself back to the earth.
