conveyance to the hideous Golgotha of the pampas.
The chance that any individual would be among the fated ones was reasonably small. It was the fashion to make a jest of the whole business. Ruth smiled as she showed her ticket.
Kay stared at it. "Ruth, if – if anything happened to you I'd go insane. I'd – "
"Why this sudden ardor, Kay?"
Kay took Ruth's small hand in his. "Ruth, you mustn't play with me any more. You know I love you. And the sight of that thing makes me almost insane. You do care, don't you?" And, as Ruth remained silent, "Ruth, it isn't Cliff Hymes, is it? I know you two are old friends. I'd rather it were Cliff than anybody else, if it had to be some one, but – tell me, Ruth!"
"It isn't Cliff," said Ruth slowly.
"Is it – some one else?"
"It's you, dear," answered Ruth. "It's always been you. It might have been Cliff if you hadn't come along. But he knows now it can never be he."
"Does he know it's me?" asked Kay, greatly relieved.
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.
"They will be cut off from the main herd," the optimistic reports announced. "We shall deal with the main herd first. This year the sacrifice will have to be made, but it will be the last. Scientists have at last hit upon an infallible toxin which will utterly destroy this menace within a few months."
Nobody believed that story, for everything had been tried and failed. In their laboratory Cliff and Kay were working frantically. And now the coldness that had developed between them was affecting their collaboration too. Cliff was keeping something back from Kay.
Kay knew it. Cliff had made some discovery that he was not sharing with his partner. Often Kay, entering the laboratory, would find Cliff furtively attempting to conceal some operation that he was in the midst of. Kay said nothing, but a brooding anger began to fill his heart. So Cliff was trying to get all the credit for the result of their years of work together!
And always, in the back of his mind, there was a vision of the little Government ticket in Ruth's hand, with the numbers in staring black type. They had burned into his brain. He could never forget them. Often at night, after a hard day's work, he would suddenly awaken out of a hideous nightmare, in which he saw Ruth taken away by the agents of the Government, to be thrown as a sacrifice to the monsters.
And Cliff was hiding something! That made the situation unbearable.
The coolness between the two men was rapidly changing into open animosity. And then one day, quite by chance, in Cliff's absence, Kay came upon evidence of Cliff's activities.
Cliff was no longer experimenting with the W-ray! He was using a new type of ray altogether, the next series, the psenium electron emanation discovered only a few years before, which had the peculiar property of non-alternation, even when the psenium electron changed its orbit around the central nucleus of the psenium atom.
Instead of discontinuity, the psenium electron had been found to emit radiation steadily, and this had upset the classic theories of matter for the ninth time in the past fifteen years.
And Kay's wrath broke loose in a storm of reproaches when Cliff came into the laboratory.
"You've been deliberately keeping me in the dark!" he shouted. "You're a nice sort of partner to have! Here's where we split up the combination, Hynes!"
"I've been thinking that for a long time," sneered Cliff. "The fact is, Kay, you're a little too elementary in your ideas to suit me. It's due to you that I kept hammering away on the wrong tack for years. The sooner we part, the better."
"No time like now," said Kay. "Keep your laboratory. You put most of the money into it, anyway. I'll build me another – where I can work without being hampered by a partner who's out for himself all the time. Good luck to you in your researches, and I hope you'll get all the credit when you find a way of annihilating the Earth Giants."
And he stormed out of the laboratory, jumped into his plane, and winged his way southward toward his apartment in New York.
Crowds in the streets of every town on the way. In villages and hamlets, swarming like ants, and hurrying along the highways! Kay, who flew one of the slow, old-fashioned planes, averaging little more than a hundred miles an hour, winged his way methodically overhead, too much absorbed in his anger against Cliff to pay much attention to this phenomenon at first. But gradually it was borne in upon him that something was wrong.
He flew lower, and now he was passing over a substantial town, and he could hear the shouts of anger that came up to him.
