<passage>:
some stronger intelligence reaches out from the dimensional shadows of the very space we live in and wrests from us the other minds in the other dimension. Man had waged a war and war had bred a pestilence. And the whole vast cycle of events was but a detail of a cyclopean plan. He could see it all now. By an insidious mass hypnosis minions from that other dimension ... or was it one supreme intelligence ... had deliberately sown the seeds of dissension. The reduction of the world's mental power had been carefully planned with diabolic premeditation. On impulse he suddenly turned, crossed the room and opened the him. Even the man at the Red Star confectionery, where he bought his cigar, remained silent while the purchase was being made. Mr. Chambers merely tapped on the glass top of the counter with a coin, the man reached in and brought forth the box, and Mr. Chambers took his cigar. That was all. For people long ago had gathered that Mr. Chambers desired to be left alone. The newer generation of townsfolk called it power of some greater mind. The street was gone. The rest of his house was gone. This room revolutionary to cost Mr. Chambers his post at the university. A silver moon shone over the chimney tops and a chill, impish October wind was rustling the dead leaves when Mr. Chambers And the face ... the face of magnitude ... of power of cosmic craft and evil.... of Oak and Jefferson was waiting for him once again and came out Mr. Chambers turned his eyes back into the room. The clock was ticking slowly, steadily. The greyness was stealing into the room. was blurting floated to Mr. Chambers. snarling and growling, snapping at his heels. But Mr. Chambers A radio was blaring down the street and faint wisps of what it pretended not to notice and the beast gave up the chase. "... still taking place ... Empire State building disappeared ... thin air ... famed scientist, Dr. Edmund Harcourt...." The wind whipped the muted words away and Mr. Chambers grumbled Mr. Chambers had written. But he pushed speculation away, sniffed the clean, crisp air again, looked at the familiar things that materialized out of the late That was a tenet he had laid down twenty years ago. There was a crowd of men in front of the drugstore at the corner of Oak and Lincoln and they were talking excitedly. Mr. Chambers caught some excited words: "It's happening everywhere.... What do you think it is.... The scientists can't explain...." But as Mr. Chambers neared them they fell into what seemed an abashed silence and watched him pass. He, on his part, gave them waited for it. The room, or what was left of it, plunged into dreadful silence. Mr. Chambers started. The clock had stopped. Funny ... the first He had no cigar. For the first time he had neglected to purchase his evening smoke. Shaken, muttering to himself, Mr. Chambers let himself in his house and locked the door behind him. He hung his hat and coat on the rack in the hall and walked Silence filled the room. A silence that was measured by the ticking of the old fashioned pendulum clock on the mantelpiece. But silence was no strange thing to Mr. Chambers. Once he had loved music ... the kind of music he could get by tuning in Every detail of the room was engraved in his mind with ... clarity 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 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, then stopped as he realized the room must be warm. A fire blazed merrily in the grate. The cold he felt came from something ... 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 upon the mantel. Mr. Chambers got to his feet, strode to the door, opened it and looked out. Moonlight tesselated the street in black and silver, etching the Gulping in fright, Mr. Chambers slammed the door shut, locked it and double bolted it. Then he went to his bedroom and took two sleeping powders. them, lost the keen edge of fantastic terror that lurked around them. The light through the windows slowly grew brighter. Mr. Chambers looked. Mr. Chambers was sure of that. And now he saw the faint outlines of his neighbor's house ... but first shelf, his many scientific works on the lower shelves. The second shelf contained but one book. And it was around this book that Mr. Chambers' entire life was centered. Twenty years ago he had written it and foolishly attempted to teach its philosophy to a class of undergraduates. The newspapers, he It was a simple book, really, dismissed by most authorities as merely the vagaries of an over-zealous mind. Mr. Chambers took it down now, opened its cover and began thumbing slowly through the pages. For a moment the memory of happier days swept over him. 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 only with matter's form. For while the mind of man through long ages may have moulded an imagery of that space in which he lives, mind would have little conceivable influence upon the existence 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 our world will dissolve beneath our feet and before our eyes as some stronger intelligence reaches out from the dimensional shadows of the very space we live in and wrests from us the 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 dimension was fighting to supersede man's control and take his universe into its own plane! 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. him. It seemed to ricochet up and into the higher levels of the sky, as if a giant door had been opened to a mighty room high above him. And beyond, like a final backdrop, rose a titanic wall. It was from that wall ... from its crenelated parapets and battlements that Mr. Chambers felt the eyes peering at him. Thousands of eyes glaring down with but a single purpose. And as he continued to look, something else seemed to take form the vision faded like a darkened magic-lantern, and the grayness moved in again. Mr. Chambers pushed open the door of his house. But he did not lock it. There was no need of locks ... not any more. A few coals of fire still smouldered in the grate and going go. 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. 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 our world will dissolve beneath our feet and before our eyes as
