Be this as it may, the fact could not be gainsaid that Last Bull was growing more and more morose. The spectators, strolling along the wide walk which skirted the front of his range, seemed to irritate him, and sometimes, when a group had gathered to admire him, he would turn his low-hung head and answer their staring eyes with a kind of heavy fury, as if he burned to break forth upon them and seek vengeance for incalculable wrongs. This smouldering indignation against humanity extended equally, if not more violently, to all creatures who appeared to him as servants or allies of humanity. The dogs whom he sometimes saw passing, held in leash by their masters or mistresses, made him paw the earth scornfully if he happened to be near the fence. The patient horses who pulled the road-roller or the noisy lawn-mower made his eyes redden savagely. And he hated with peculiar zest the roguish little trick elephant, Bong, who would sometimes, his inquisitive trunk swinging from side to side, go lurching lazily by with a load of squealing children on his back.

Bong, who was a favored character, amiable and trustworthy, was allowed the freedom of the Park in the early morning, before visitors began to arrive who might be alarmed at seeing an elephant at large. He was addicted to minding his own business, and never paid the slightest attention to any occupants of cage or enclosure. He was quite unaware of the hostility which he had aroused in the perverse and brooding heart of Last Bull.

One crisp morning in late November, when all the grass in the Park had been blackened by frost, and the pools were edged with silver rims of ice, and mists were white and saffron about the scarce-risen sun, and that autumn thrill was in the air which gives one such an appetite, Bong chanced to be strolling past the front of Last Bull’s range. He did not see Last Bull, who was nothing to him. But, being just as hungry as he ought to be on so stimulating a morning, he did see, and note with interest, some bundles of fresh hay on the other side of the fence.

Now, Bong was no thief. But hay had always seemed to him a free largess, like grass and water, and this looked like very good hay. So clear a conscience had he on the subject that he never thought of glancing around to see if any of the attendants were looking. Innocently he lurched up to the fence, reached his lithe trunk through, gathered a neat wisp of the hay, and stuffed it happily into his curious, narrow, pointed mouth. Yes, he had not been mistaken. It was good hay. With great satisfaction he reached in for another mouthful.

Last Bull, as it happened, was standing close by, but a little to one side. He had been ignoring, so far, his morning ration. He was not hungry. And, moreover, he rather disapproved of the hay because it had the hostile man-smell strong upon it. Nevertheless, he recognized it very clearly as his property, to be eaten when he should feel inclined to eat it. His wrath, then, was only equalled by his amazement when he saw the little elephant’s presumptuous gray trunk reach in and coolly help itself. For a moment he forgot to do anything whatever about it. But when, a few seconds later, that long, curling trunk of Bong’s insinuated itself again and appropriated another bundle of the now precious hay, the outraged owner bestirred himself. With a curt roar, that was more of a cough or a grunt than a bellow, he lunged forward and strove to pin the intruding trunk to the ground.

With startled alacrity Bong withdrew his trunk, but just in time to save it from being mangled. For an instant he stood with the member held high in air, bewildered by what seemed to him such a gratuitous attack. Then his twinkling little eyes began to blaze, and he trumpeted shrilly with anger. The next moment, reaching over the fence, he brought down the trunk on Last Bull’s hump with such a terrible flail-like blow that the great buffalo stumbled forward upon his knees.

He was up again in an instant and hurling himself madly against the inexorable steel which separated him from his foe. Bong hesitated for a second, then, reaching over the fence once more, clutched Last Bull maliciously around the base of his horns and tried to twist his neck. This enterprise, however, was too much even for the elephant’s titanic powers, for Last Bull’s greatest strength lay in the muscles of his ponderous and corded neck. Raving and bellowing, he plunged this way and that, striving in vain to wrench himself free from that incomprehensible, snake-like thing which had fastened upon him. Bong, trumpeting savagely, braced himself with widespread pillars of legs, and between them it seemed that the steel fence must go down under such cataclysmic shocks as it was suffering. But the noisy violence of the battle presently brought its own ending. An amused but angry squad of attendants came up and stopped it, and Bong, who seemed plainly the aggressor, was hustled off to his stall in deep disgrace.

Last Bull was humiliated. In this encounter things had happened which he could in no way comprehend; and though, beyond an aching in neck and shoulders, he felt none the worse physically, he had nevertheless a sense of having been worsted, of having been treated with ignominy, in spite of the fact that it was his foe, and not he, who had retired from the field. For several days he wore a subdued air and kept about meekly with his docile cows. Then his old, bitter moodiness reasserted itself, and he resumed his solitary broodings on the crest of the knoll.

When the winter storms came on, it had been Last Bull’s custom to let himself be housed luxuriously at nightfall, with the rest of the herd, in the warm and ample buffalo-shed. But this winter he made such difficulty about going in that at last Payne decreed that he should have his own way and stay out. “It will do him no harm, and may cool his peppery blood some!” had been the keeper’s decision. So the door was left open, and Last Bull entered or refrained, according to his whim. It was noticed, however, – and this struck a chord of answering sympathy in the plainsman’s imaginative temperament, – that, though on ordinary nights he might come in and stay with the herd under shelter, on nights of driving storm, if the tempest blew from the west or northwest, Last Bull was sure to be out on the naked knoll to face it. When the fine sleet or stinging rain drove past him, filling his nostrils with their cold, drenching his matted mane, and lashing his narrowed eyes, what visions swept through his troubled, half-comprehending brain, no one may know. But Payne, with understanding born of sympathy and a common native soil, catching sight of his dark bulk under the dark of the low sky, was wont to declare that he knew. He would say that Last Bull’s eyes discerned, black under the hurricane, but lit strangely with the flash of keen horns and rolling eyes and frothed nostrils, the endless and innumerable droves of the buffalo, with the plains wolf skulking on their flanks, passing, passing, southward into the final dark. In the roar of the wind, declared Payne, Last Bull, out there in the night, listened to the trampling of all those vanished droves. And though the other keepers insisted to each other, quite privately, that their chief talked a lot of nonsense about “that there mean-tempered old buffalo,” they nevertheless came gradually to look upon Last Bull with a kind of awe, and to regard his surly whims as privileged.

It chanced that winter that men were driving a railway tunnel beneath a corner of the Park. The tunnel ran for a short distance under the front of Last Bull’s range, and passed close by the picturesque cottage occupied by Payne and two of his assistants. At this point the level of the Park was low, and the shell of earth was thin above the tunnel roof.

There came a Sunday afternoon, after days of rain and penetrating January thaw, when sun and air combined to cheat the earth with an illusion of spring. The buds and the mould breathed of April, and gay crowds flocked to the Park, to make the most of winter’s temporary repulse. Just when things were at their gayest, with children’s voices clamoring everywhere like starlings, and Bong, the little elephant, swinging good-naturedly up the broad white track with all the load he had room for on his back, there came an ominous jar and rumble, like the first of an earthquake, which ran along the front of Last Bull’s range.

With sure instinct, Bong turned tail and fled with his young charges away across the grassland. The crowds, hardly knowing what they fled from, with screams and cries and blanched faces, followed the elephant’s example. A moment later and, with a muffled crash, all along the front of the range, the earth sank into the tunnel, carrying with it half a dozen panels of Last Bull’s hated fence.

Almost in a moment the panic of the crowd subsided. Every one realized just what had happened. Moreover, thanks to Bong’s timely alarm, every one had got out of the way in good season. All fear of earthquake being removed, the crowd flocked back eagerly to stare down into the wrecked tunnel, which formed now a sort of gaping, chaotic ditch, with sides at some points precipitous and at others brokenly sloping. The throng was noisy with excited interest and with relief at having escaped so cleanly. The break had run just beneath one corner of the keepers’ cottage, tearing away a portion of the foundation and wrenching the structure slightly aside without overthrowing it. Payne, who had been in the midst of his Sunday toilet, came out upon his twisted porch, half undressed and with a shaving-brush covered with lather in his hand. He gave one look at the damage which had been wrought, then plunged indoors again to throw his clothes on, at the same time sounding the hurry call for the attendants in other quarters of the Park.

Last Bull, who had been standing on his knoll, with his back to the throngs, had wheeled in astonishment at the heavy sound of the cave-in. For a few minutes he had stared sullenly, not grasping the situation. Then very slowly it dawned on him that his prison walls had fallen. Yes, surely, there at last lay his way to freedom, his path to the great open spaces for which he dumbly and vaguely hungered. With stately deliberation he marched down from his knoll to investigate.

But presently another idea came into his slow mind. He saw the clamorous crowds flocking back and ranging themselves along the edge of the chasm. These were his enemies. They were coming to balk him. A terrible madness surged through all his veins. He bellowed savage warning and came thundering down the field, nose to earth, dark, mountainous, irresistible.

The crowd yelled and shrank back. “He can’t get across!” shouted some. But others cried: “He can! He’s coming! Save yourselves!” And with shrieks they scattered wildly across the open, making for the kiosks, the pavilions, the trees, anything that seemed to promise hiding or shelter from that onrushing doom.

At the edge of the chasm – at this point forming not an actual drop, but a broken slide – Last Bull hardly paused. He plunged down, rolled over in the débris, struggled to his feet again instantly, and went ploughing and snorting up the opposite steep. As his colossal front, matted with mud, loomed up over the brink, his little eyes rolling and flaming, and the froth flying from his red nostrils, he formed a very nightmare of horror to those fugitives who dared to look behind them.

Surmounting the brink, he paused. There were so many enemies, he knew not which to pursue first. But straight ahead, in the very middle of the open, and far from any shelter, he saw a huddled group of children and nurses fleeing impotently and aimlessly. Shrill cries came from the cluster, which danced with colors, scarlet and yellow and blue and vivid pink. To the mad buffalo, these were the most conspicuous and the loudest of his foes, and therefore the most dangerous. With a bellow he flung his tail straight in the air, and charged after them.

An appalling hush fell, for a few heart-beats, all over the field. Then from different quarters appeared uniformed attendants, racing and shouting frantically to divert the bull’s attention. From fleeing groups black-coated men leapt forth, armed only with their walking-sticks, and rushed desperately to defend the flock of children, who now, in the extremity of their terror, were tumbling as they ran. Some of the nurses were fleeing far in front, while others, the faithful ones, with eyes starting from their heads, grabbed up their little charges and struggled on under the burden.

Already Last Bull was halfway across the space which divided him from his foes. The ground shook under his ponderous gallop. At this moment Payne reappeared on the broken porch.

One glance showed him that no one was near enough to intervene. With a face stern and sorrowful he lifted the deadly .405 Winchester which he had brought out with him. The spot he covered was just behind Last Bull’s mighty shoulder.

The smokeless powder spoke with a small, venomous report, unlike the black powder’s noisy reverberation. Last Bull stumbled. But recovering himself instantly, he rushed on. He was hurt, and he felt it was those fleeing foes who had done it. A shade of perplexity darkened Payne’s face. He fired again. This time his aim was true. The heavy expanding bullet tore straight through bone and muscle and heart, and Last Bull lurched forward upon his head, ploughing up the turf for yards. As his mad eyes softened and filmed, he saw once more, perhaps, – or so the heavy-hearted keeper who had slain him would have us believe, – the shadowy plains unrolling under the wild sky, and the hosts of his vanished kindred drifting past into the dark.
