"It sickens you," said Eve, "and it sickens me also, for death and decay are not pleasant. Yet Nature, left to herself, reduces all to this. Every grave that has yawned to receive its prey hides corruption no less shocking. Nature's forces of creation and destruction forever work in partnership. Never satisfied with her composition, she destroys and starts again, building, building towards the ultimate of perfection. Thus, it is natural that if Dr. Mundson isolated the Life Ray, Nature's supreme force of compensation, isolation of the Death Ray should closely follow. Adam, thirsting for power, has succeeded. A few sweeps of his unholy ray of decomposition will undo all Dr. Mundson's work in this valley and reduce it to a stinking holocaust of destruction. And the time for his striking has come!" She seized his face and drew it toward her. "Quick!" she said. "We'll have to go back to the third dimension. I could leave you safe in the fourth, but if anything should happen to me, you would be stranded forever in future time." She kissed his lips. In a moment, he was back in the old familiar world, where right is right and left is left. Again the subtle change wrought by Eve's magic lips had taken place. * * * * * Eve went to a machine standing in a corner of the room. "Come here and get behind me, John Northwood. I want to test it before he enters." Northwood stood behind her shoulder. "Now watch!" she ordered. "I shall turn it on one of those cages of guinea pigs over there." She swung the projector around, pointed it at the cage of small, squealing animals, and threw a lever. Instantly a cone of black mephitis shot forth, a loathsome, bituminous stream of putrefaction that reeked of the grave and the cesspool, of the utmost reaches of decay before the dust accepts the disintegrated atoms. The first touch of seething, pitchy destruction brought screams of sudden agony from the guinea pigs, but the screams were cut short as the little animals fell in shocking, instant decay. The very cage which imprisoned them shriveled and retreated from the hellish, devouring breath that struck its noisome rot into the heart of the wood and the metal, reducing both to revolting ruin. Eve cut off the frightful power, and the black cone disappeared, leaving the room putrid with its defilement. "And Adam would do that to the world," she said, her blue eyes like electric-shot icicles. "He would do it to you, John Northwood--and to me!" Her full bosom strained under the passion beneath. "Listen!" She raised her hand warningly. "He comes! The destroyer comes!" * * * * * A hand was at the door. Eve reached for the lever, and, the same moment, Northwood leaned over her imploringly. "If Athalia is with him!" he gasped. "You will not harm her?" A wild shriek at the door, a slight scuffle, and then the doorknob was wrenched as though two were fighting over it.
