Ruth inclined her head. "He took it very finely," she said. "He said just what you've said about him. Oh, Kay, if only your experiment had succeeded, and the world could be free of this nightmare! What happened? Why couldn't you and Cliff make it destroy life?" "I don't know, dear," answered Kay. "Iron and steel melt into powder at the least impact of the rays. They are so powerful that there was even a leakage through the rubber and anelektron container. Even the craolite socket was partly fused, and that is supposed to be an impossibility. And there was a hole in the ground seven feet deep where the very mineral water in the earth had been dissolved. But against organic substances the W-ray is powerless. "Next year, dear--next year we'll have solved our problem, and then we'll free the world of this menace, this nightmare. Ruth--don't let's talk about that now. I love you!" They kissed. The Earth Giants faded out of their consciousness even while Ruth held that ominous ticket in her hand. * * * * * Kay said nothing to Cliff about it, but Cliff knew. Perhaps he had put his fate to the test with Ruth and learned the truth from her. Ruth made no reference to the matter when she saw Kay. But between the two men, friends for years, a coolness was inexorably developing. They had gone to work on the new machine. They were hopeful. When they were working, they forgot their rivalry. "You see, Kay," said Cliff, "we mustn't forget that the Millikan rays have been bombarding Earth since Earth became a planet, out of the depths of space. It is their very nature not to injure organic life, otherwise all life on Earth would have been destroyed long ago. Now, our process is only an adaptation of these cosmic rays. We haven't changed their nature." "No," agreed Kay. "What we want is a death-ray strong enough to obliterate these monsters, without simply disintegrating them and creating new fragments to bud into the complete being. Why do you suppose they are so tenacious of life, Cliff?" "They represent primeval man, life itself, striving to organize itself, and nothing is more tenacious than the life principle," answered Cliff. Meanwhile the fatal weeks were passing. A few days after the tickets had been distributed, a Government notice was broadcasted and published, ordaining that, in view of former dissensions, no substitutes for the condemned persons would be permitted. Rich or poor, each of the victims chosen by lot must meet his fate. * * * * * And the monsters were growing active. There had been an extension of their activities. Tongues had been creeping up the rivers that ran into the Amazon. Suddenly a dense mass of the devils had appeared on the north coast, near Georgetown. They had overleaped the Amazon; they were overrunning British Guiana, eating up everything on their way. Georgetown was abandoned; the monsters were in complete control.
