matter which we know to be our own. But there had been no need to wait for that distant day. Scant years after he had written those prophetic words the thing was He could see it all now. By an insidious mass hypnosis minions from that other dimension ... or was it one supreme intelligence ... had world's mental power had been carefully planned with diabolic premeditation. On impulse he suddenly turned, crossed the room and opened the Weakly Mr. Chambers moved back to his chair in the corner. For people long ago had gathered that Mr. Chambers desired to be "So here I am," he said, half aloud. So there he was. Embattled in the last corner of the world that left alone. The newer generation of townsfolk called it eccentricity. Certain uncouth persons had a different word for revolutionary to cost Mr. Chambers his post at the university. October wind was rustling the dead leaves when Mr. Chambers snarling and growling, snapping at his heels. But Mr. Chambers was blurting floated to Mr. Chambers. "Oh, well," said Mr. Chambers, "I never did like that very well." The wind whipped the muted words away and Mr. Chambers grumbled Something one could expect to happen. Perhaps, if he thought hard enough, he could bring them back. But, after all, what was the use? One man, alone, could not stand Mr. Chambers had written. off the irresistible march of nothingness. One man, all alone, simply couldn't do it. But he pushed speculation away, sniffed the clean, crisp air again, absolutely nothing in the world ... that he would let upset him. That was a tenet he had laid down twenty years ago. of Oak and Lincoln and they were talking excitedly. Mr. Chambers He wondered if he would retain his individuality ... if he still would be a person. Or would he merely be a thing? There was one answer to all of that. He simply didn't know. But as Mr. Chambers neared them they fell into what seemed an Nothingness advanced upon him, ate its way across the room, Now.... It wasn't until then that he realized something else was wrong. Shaken, muttering to himself, Mr. Chambers let himself in his had forgotten his cigar. Huddled in the chair, he frowned slowly. It was disquieting to have something like that happen. There must be something wrong. Had his long exile finally turned his mind ... perhaps just a very little ... enough to make him queer? Had he lost his sense of proportion, of perspective? in his line of vision. He could see it without turning his head. He had put it there because he liked it best. Further reverie became an effort as Mr. Chambers felt himself succumbing to weariness. He undressed and went to bed. For an hour he lay awake, assailed by vague fears he could neither When finally he dozed off it was to lose himself in a series of horrific dreams. He dreamed first that he was a castaway on a thought, passed the store as on the night before? For the first time in twenty years, Mr. Chambers retraced his again, where he stood astounded while a single, incredible fact grew slowly in his brain: Was something happening in the world which he, in his secluded life, knew nothing about? Mr. Chambers shivered, reached to turn up the collar of his coat, he had ever sensed before. Not a homey, comfortable silence ... but a silence that hinted at emptiness and nothingness. There was something back of this, Mr. Chambers told himself. Something that reached far back into one corner of his brain and demanded recognition. Something tied up with the fragments of talk he had heard on the drugstore corner, bits of news And somehow those gruesome statistics seemed tied up with his own experience. Something, somewhere, some part of his earlier life, seemed to hold an explanation. But try as he would his befuddled brain failed to find the answer. The pendulum clock struck slowly, its every other chime as usual Gulping in fright, Mr. Chambers slammed the door shut, locked it The light through the windows slowly grew brighter. Mr. Chambers The tree was there now. But it hadn't been when he first had looked. Mr. Chambers was sure of that. and wrenched it out of true. Like the house he had seen across the street the night before, the house that had painfully righted itself when he thought of how it should look. too might right itself. But Mr. Chambers was very weary. Too of some anti-rational cult, had forced his expulsion from the school. It was a simple book, really, dismissed by most authorities as Then his eyes focused on the paragraph, a paragraph written so long ago the very words seemed strange and unreal: Man himself, by the power of mass suggestion, holds the physical fate of this earth ... yes, even the universe. Billions of minds seeing trees as trees, houses as houses, streets as streets ... entire foundation of matter, robbed of its regenerative power, will crumple and slip away like a column of sand.... always and can never be destroyed, only altered or transformed. But in modern astrophysics and mathematics we gain an insight into the possibility ... yes probability ... that there are other is two dimensional, the pin three dimensional. Yet both occupy the same space. Granting then that the power of men's minds alone holds this universe, or at least this world in its present form, may we not go farther and envision other minds in some other plane watching us, waiting, waiting craftily for the time they can take over the domination of matter? Such a concept is not impossible. It is a natural conclusion if we accept the double hypothesis: that mind does control the formation of all matter and that other worlds matter which we know to be our own. He stood astounded beside the bookcase, his eyes staring unseeing He had written that. And because of those words he had been called a heretic, had been compelled to resign his position at the university, had been forced into this hermit life. A tumultuous idea hammered at him. Men had died by the millions all over the world. Where there had been thousands of minds there blighted Africa, had reached South America ... might even have come to the United States. He remembered the whispers he had heard, the words of the men at the drugstore corner, the But abruptly the whole thing fitted together in his brain like the missing piece of a puzzle into its slot. The significance of it all gripped him with damning clarity. There were not sufficient minds in existence to retain the material world in its mundane form. Some other power from another Abruptly Mr. Chambers closed the book, shoved it back in the case and picked up his hat and coat. He had to know more. He had to find someone who could tell him. With a wild cry, Mr. Chambers turned and ran. Back down the Mr. Chambers pushed open the door of his house. But he did not But how long could he ... his brain ... maintain its existence? Mr. Chambers stared at the marine print and for a moment a little breath of reassurance returned to him. They couldn't take this gone and that fitted in the pattern ... for it would be the least familiar things that would go first. Wheeling, he stared across the room. Was it his imagination, or But as he stared at it, it became clear again, a solid, substantial thing. For a moment real fear reached out and touched him with chilly fingers. For he knew that this room no longer was proof against the thing that had happened out there on the street. Or had it really happened? Might not all this exist within his still exist, splashing the street with the red of its neon sign? Could it be that he was going mad? He had heard whispers when he had passed, whispers the gossiping housewives had not intended him to hear. And he had heard the shouting of boys when he walked by. They thought him mad. Could he be really mad? But he knew he wasn't mad. He knew that he perhaps was the sanest of all men who walked the earth. For he, and he alone, had foreseen this very thing. And the others had scoffed at him for
