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.
