Alcatraz turned constantly to meet him, whinnying a friendly greeting, but the black paid not the slightest heed to these overtures. At length he came to a quivering stand twenty yards away, head up, ears back, a very statue of an angry and proud horse. Obviously it was a challenge, but Alcatraz was too happy in his new-found brothers to think of battle. He ducked his head a little and pawed the ground lightly, a horse's age-old manner of expressing amicable intentions. But there was nothing amicable in the black leader. He reared a little and came down lightly on his forefeet, his weight gathered on his haunches as though he were preparing to charge, and at this unmistakable evidence of ill-will, Alcatraz snorted and grew alert.

If it came to fighting he was more than at home. He was a master. More than one corral gate he had cunningly worked ajar, and more than one flimsy barn wall he had broken down with his leaning shoulder, and more than one fence he had leaped to get at the horses beyond. With anger rising in him he took stock of the opponent. The black lacked a good inch of his own height but in substance more than made up for the deficiency. He was a stalwart eight-year old, muscled like a Hercules, with plenty of bone to stand his weight; and his eyes, glittering through the tangle of forelock, gave him an air of savage cunning. Decidedly here was a foeman worthy of his steel, thought Alcatraz. He looked about him. There stood the mares and the horses ranged in a loose semi-circle, waiting and watching; only the colts, ignorant of what was to come, had begun to frolic together or bother their mothers with a savage pretense of battle. Alcatraz saw one solid old bay topple her offspring with a side-swing of her head. She wanted an unobstructed view of the fight.

His interest in this by-play nearly proved his undoing for while his head was turned he heard a rushing of hoofs and barely had time to throw himself to one side as the black flashed by him. Alcatraz turned and reared to beat the insolent stranger into the earth but he found that the leader was truly different from the sluggish horses of men. A hundred wild battles had taught the black every trick of tooth and heel; and in the thick of the fight he carried his weight with the agility of a cat: Alcatraz had not yet swung himself fairly back on his haunches when the black was upon him, the dust flying up behind from the quickness of his turn. Straight at the throat of the chestnut he dived and his teeth closed on the throat of Alcatraz just where the neck narrows beneath the jaw. His superior height enabled Alcatraz to rear and fling himself clear, but his throat was bleeding when he landed on all fours dancing with rage and the sting of his wounds. Yet he refrained from rushing; he had been in too many a fight to charge blindly.

The black, however, had tasted victory, and came again with a snort of eagerness. It was the thing for which Alcatraz had been waiting and he played a trick which he had learned long before from a cunning old gelding who, on a day, had given him a bitter fight. He pitched back, as though he were about to rear to meet the charge, but when his fore-feet were barely clear of the ground he rocked down again, whirled, and lashed out with his heels.

Had they landed fairly the battle would have ended in that instant, but the black was cat-footed indeed, and he swerved in time to save his head. Even so one flashing heel had caught his shoulder and ripped it open like a knife. And they both sprang away, ready for the next clash. The grey mare who had run so gallantly at the hip of the leader now approached and stood close by with pricking ears. Alcatraz bared his teeth as he glanced aside at her. No doubt if he were knocked sprawling she would rush in to help her lord and master finish the enemy. That gave Alcatraz a second problem—to fight the stallion without turning his back on the treacherous mare.

Before he could plan his next move the black was at him again. This time they reared together, met with a clash of teeth and rapid beat of hoofs, and parted on equal terms. Alcatraz eyed his enemy with a fierce respect. His head was dull and ringing with the blows; his shoulder had been slightly cut by a glancing forehoof. Decidedly he could not meet the brawn of this hardened old warrior on such terms. He had used up one trick, he must find another, and still another; and when the black rushed again, Alcatraz slipped away from the contact and raced off at his matchless gallop. The other pursued a short distance and stopped, sounding his defiance and his triumph. As well follow the wind as the chestnut stranger. Besides, the blood was pouring from the gash in his shoulder and that foreleg was growing weak; it was well that the battle had ended at this point.

But it was not ended! Flight was not in the mind of Alcatraz as he swept away. He ran in dodging circles about the enemy, swerving in and then veering sharply out as the black reared to meet the expected charge. Whatever else was accomplished, he had gained the initiative and that plus his lightness of foot might bring matters to a decisive issue in his favor. Twice he made his rush; twice the black turned and met him with that shower of crushing blows with the fore hoofs. But the third time a feint at one side and a charge at the other took the leader unawares. Fair and true the shoulder of Alcatraz struck him on the side and the impact flung the black heavily to the earth. The shock had staggered even Alcatraz but he was at the other like a savage terrier. Thrice he stamped across that struggling body until the black lay motionless with his coat crimson from twenty slashes. Then Alcatraz drew away and neighed his triumph, and in his exultation he noted that the herd drew close together at his call.

Why, he could not imagine, and he had no time to ponder on it, for the black was now struggling to his feet. But there was no fight left in him. He stood dazed, with fallen head, and to the challenge of the chestnut he replied by not so much as the pricking of his flagging ears.

The grey mare went to him, touched noses with her overlord, and then backed away, shaking her head. Presently she trotted past Alcatraz, flung up her heels within an inch of his head, and then galloped on towards the herd looking back at the conqueror. Oh vanity of the weaker sex; oh frailty! She had seen her master crushed and within the minute she was flirting with the conqueror.

The herd started off as the grey joined them and Alcatraz followed; the black leader remaining unmoving and the blood dripped steadily down his legs.
