Came now a little silence. Beside Stern the girl sat, half supporting his wounded body with her firm, white arm. Thirst was beginning to torment them both, particularly Stern, whose injuries had already given him a marked temperature. But water there was absolutely none. And so, still planless, glad only to recuperate a little, content that for the present the Horde had been held back, they waited. Waiting, they both thought. The girl's thoughts were all of him; but he, man-fashion, was trying to piece out what had happened, to frame some coherent idea of it all, to analyze the urgent necessities that lay upon them both. Here and there, a disjointed bit recurred to him, even from out of the delirium that had followed the blow on the head. From the time he had recovered his senses in the building, things were clearer. He knew that the Horde, temporarily frightened by his mad rush, had given him time to stumble up again and once more lift the girl, before they had ventured to creep into the arcade in search of their prey. He remembered that the spear had been gone then. Raving, he must have broken and plucked it out. The blood, he recalled, was spurting freely as he had carried Beatrice through the wreckage and up to the first landing, where she had regained partial consciousness. Then he shuddered at recollection of that stealthy, apelike creeping of the Horde scouts in among the ruins, furtive and silent; their sniffing after the blood-track; their frightful agility in clambering with feet and hands alike, swinging themselves up like chimpanzees, swarming aloft on the death-hunt. He had evaded them, from story to story. Beatrice, able now to walk, had helped him roll down balustrades and building-stones, fling rocks, wrench stairs loose and block the way. And so, wounding their pursuers, yet tracked always by more and ever more, they had come to the landing, where by aid of the rifle barrel as a lever they had been able to bring a whole wall crashing down, to choke the passage. That had brought silence. For a time, at least, pursuit had been abandoned. In the sliding, dusty avalanche of the wall, hurled down the stairway, Stern knew by the grunts and shrieks which had arisen that some of the Horde had surely perished--how many, he could not tell. A score or two at the very least, he ardently hoped. Fear, at any rate, had been temporarily injected into the rest. For the attack had not yet been renewed. Outside in the forest, no sign of the Horde, no sound. A disconcerting, ominous calm had settled like a pall. Even the birds, recovered from their terrors, had begun to hop about and take up their twittering little household tasks. As in a kind of clairvoyance, the engineer seemed to know there would be respite until night. For a little while, at least, there could be rest and peace. But when darkness should have settled down--
