The Big Business Man appeared not so sanguine, but said nothing. Finally they came to one of the large amphitheaters into which several of the tunnels opened. In size, it appeared to them now a hundred feet in length and with a roof some twelve feet high. The Chemist stopped to let the others come up. "I think our best route is there," he pointed. "It is not so high a tunnel; we shall have to get smaller. Beyond it they are larger again. It is not far--half an hour, perhaps, walking as we----" A cry from Aura interrupted him. "My brother, see, they come," she exclaimed. Before them, out of several of the smaller passageways, a crowd of little figures was pouring. There were no shouts; there was seemingly no confusion; just a steady, flowing stream of human forms, emptying from the tunnels into the amphitheater and spreading out over its open surface. The fugitives stared a moment in horror. "Good God! they've got us," the Doctor muttered, breaking the tenseness of the silence. The little people kept their distance at first, and then as the open space filled up, slowly they began coming closer, in little waves of movement, irresistible as an incoming tide. Aura turned towards the passageway through which they had entered. "We can go back," she said. And then. "No--see, they come there, too." A crowd of the little gray figures blocked that entrance also--a crowd that hesitated an instant and then came forward, spreading out fan-shape as it came. The Big Business Man doubled up his fists. "It's fight," he said grimly. "By God! we'll----" but Lylda, with a low cry, flung herself before him. "No, no," she said passionately. "Not that; it cannot be that now, just at the last----" Aura laid a hand upon her sister's shoulder. "Wait, my sister," she said gently. "There is no matter of justice here--for you, a woman--to decide. This is for men to deal with--a matter for men--our men. And what they say to do--that must be done." She turned to the Chemist and the Very Young Man, who were standing side by side. "A woman--cannot kill," she said slowly. "Unless--her man--says it so. Or if to save him----" Her eyes flashed fire; she held her slim little body erect and rigid--an Amazon ready to fight to the death for those she loved. The Chemist hesitated a moment. Before he could answer, a single shrill cry sounded from somewhere out in the silent, menacing throng. As though at a signal, a thousand little voices took it up, and with a great rush the crowd swept forward. In the first moment of surprise and indecision the group of fugitives stood motionless. As the wave of little, struggling human forms closed in around them, the Very Young Man came to himself with a start. He looked down. They were black around him now, swaying back and forth about his legs. Most of them were men, armed with the short, broad-bladed swords, or with smaller knives. Some brandished other improvised weapons; still others held rocks in their hands.
