People in crowded Oriental villages running amok, shot down by the police. A Miami surgeon at an operation killed his patient with a sudden vicious stroke and cried like a child that he had done it. A thousand incongruous, horrible incidents. From every quarter of the earth, medical authorities, scientific bodies and governments were demanding an explanation of Miami. And then the world of the Infra-red began showing. Not only to the infirm--to every one. The strongest man was frightened--terrified, sometimes, at his own mad desire to laugh. Vague red shapes were in the air, murmuring, chattering. I personally did not experience any of this. Father and the others say it was at first like the sensations we had felt on Xenephrene. The red things were not so tangible or visible--nor so clearly audible, perhaps. Not at first. But every hour, every moment, they were intensifying. Soon, it was far worse. The world could not understand, but the authorities in Miami knew at once what was happening--that Graff was using the Red Control. It promised disaster; worse, a fate unspeakable--the world gone mad. The confusion of the Miami authorities now hastily assembled again in conference, was intensified by the red hysteria which was affecting them, as every one else. Hulda was there; she says it was a bedlam within an hour. She sat quietly watching and listening to the red things coming out from their invisible world. She sat there terrified, not of them so much, for to her they were familiar things--terrified at what they were doing to our world. A bedlam surged around her, in which father, Freddie and Dan strove to hold a sanity. The President of our United States, listening to what was being reported from abroad, burst into tears. He had never been in robust health; the strain of the past few days had worn his nerves nearly to the breaking point. They took him away, and by then he was laughing and raging alternately. Out at the beach some one had given orders for the searchlight to signal a world surrender. There was no enemy to see it; but no one thought of that. It was wavering up into the sky; but no one in the War Department heeded it. Then it held steady. Then a shouting throng of people rushed it; smashed it. Father, Freddie and Dan were busy getting the equipment they had brought from Xenephrene into hasty use. The insulated suits were unnecessary. The Infra-red glasses and ear-grids were able to bar out this storming red world. The officials donned them. With normality regained they sat together trying sanely to determine what should be done. A world going mad around them. Even as they sat, news of the glasses and ear-grids had spread into the city; a mob was surging around the building, shouting demands that the glasses be distributed to them. A few hundred glasses and ear-grids, needed by our fighting aviators, and now the hundreds of millions of people would be demanding them!
