Taubo marched forth with a loud beating of drums and delivered a wailing chant which again captured his audience. He capered about the reading invader and raced to the points of a star he was drawing on the ground with a wand.

  When he had finished a long show of this, he gave an imperceptible signal to a follower and suddenly pointed his wand at a point of the star.

  Flame burst.

  To the crowd it appeared as though the ground itself was on fire. The smoke rolled and the flames rose pale yellow and smoking in the daylight. At the exact center of the star sat the reader of books.

  The fire swept forward, leaped higher. It came to the invader’s toes. The drums rolled a heavy, rising storm. The flames went under the invader’s feet! Then the smoke was thick and the crowd could not see. But the chair was charring. The entire star was burning in the sand. It was obvious that nothing human could live in that “magic” fire!

  Slowly the spent flames died down. The smoke blew aside. Taubo stared.

  The invader turned another page!

  The entire arena came to its feet with a moan. Taubo started forward. He was becoming red in the face. He had his wand lifted to strike and the shaking tension within tore at him. He moved another step forward, wand still raised. And then he fell, headlong, dead.

  If those three thousand humanoids could have moved, they would have done so. They could not. From terror they stood as though tied.

  The invader glanced up at the sun, saw that it was overhead and rose from the chair. Finger keeping his place, he walked straight toward the pennons which marked his side. He passed into the curtain and out of sight.

  The crowd, chiefs and all, would have run away if Angus had not instantly come out. He marched straight to the bank of notables.

  His hair was wet with sweat, his face was black with grime. He stopped and looked at the chiefs.

  “You have seen how impervious science is to magic,” he said. “I ask you to concede that I have won and that all my demands must therefore be fulfilled. I shall not kill you. I shall help you, for science does not kill, it saves. Do you acknowledge my sovereignty on this planet in the name of the Galactic Council and the Civil Affairs Branch of the Military Defense?”

  They took in his words. They realized that he was not that instant going to kill them. And then they looked at the body of Taubo and sensed somehow that they were free of a thing they could not describe.

  They looked at Angus McBane with his lank black hair and his soiled tunic and his cane and suddenly, as the chiefs rose to assent, the humanoids began to cheer. They cheered louder and louder and babies cried and dogs barked, and sound rose in an enthusiasm which was loud enough to be physical force.

  “You hear the people,” said the high chief. “I hear the people. We acknowledge your science and assent to your rule. You are our lord and your person is sacred unto us forevermore.”

  Angus bowed and walked back through the swelling din to the curtains and the enclosure.

  That evening Angus McBane, Civil Affairs, sent off a laconic dispatch to his superiors.

  DELTOIDS WILL NOT OBJECT TO MINING OPERATIONS. EQUIPMENT MAY BE SENT AT ANY TIME.

  MCBANE

  In the machine shop, meanwhile, of the Argus 48 Sergeant Dirk finished his careful neutralizing, according to McBane’s directions, of the robot McBane had designed and he had built. It was not a very good likeness of McBane anyway, and besides, they needed the parts. McBane regretted the destruction of one perfectly good book.

  The Dangerous Dimension

  Author’s Note

  For reasons pertinent to the happiness of Mankind, by request from the United States Philosophic Society and the refusal of Dr. Henry Mudge, Ph.D., of Yamouth University, the philosophic equation mentioned herein is presented as only Equation C without further expansion.

  The Dangerous Dimension

  THE room was neither mean nor dingy. It was only cluttered. The great bookcases had gaps in their ranks and the fallen members lay limp-leaved on floor and table. The carpet was a snowdrift of wasted paper. The stuffed owl on the mantel was awry because the lined books there had fallen sideways, knocking the owl around and over to peck dismally at China on the globe of the world. The writing desk was heaped with tottering paper towers.

  And still Dr. Mudge worked on.

  His spectacles worried him because they kept falling down in front of his eyes; a spot of ink was on his nose and his right hand was stained blue black.

  The world could have exploded without in the least disturbing Yamouth’s philosophic professor. In his head whirled a maelstrom of philosophy, physics and higher mathematics and, if examined from within, he would have seemed a very brave man.

  Examined from without it was a different matter. For one thing Dr. Mudge was thin, for another he was bald. He was a small man and his head was far too big for his body. His nose was long and his eyes were unusually bright. His thin hands gripped book and pen as every atom of his being was concentrated upon his work.

  Once he glanced up at the clock with a worried scowl. It was six-thirty and he must be done in half an hour. He had to be done in half an hour. That would give him just time enough to rush down to the university and address the United States Philosophic Society.

  He had not counted on this abrupt stab of mental lightning. He had thought to deliver a calm address on the subject, “Was Spinoza Right in Turning Down the Professorship of . . .” But when he had begun to delve for a key to Spinoza, a truly wonderful idea had struck him and out he had sailed, at two that day, to dwell wholly in thought. He did not even know that he was cramped from sitting so long in one place.

  “Henrrreeee!” came the clarion call.

  Henry failed to hear it.

  “HENrrrry!”

  Again he did not look up.

  “HENRY MUDGE! Are you going to come in here and eat your dinner or not?!”

  He heard that time, but with less than half an ear. He did not come fully back to the world of beefsteak and mashed potatoes until Mrs. Doolin, his housekeeper, stood like a thundercloud in the study door. She was a big woman with what might be described as a forceful personality. She was very righteous, and when she saw the state of that study she drew herself up something on the order of a general about to order an execution.

  “Henry! What have you been doing? And look at you! A smudge on your nose—and an ink spot on your coat!”

  Henry might fight the universe, but Mrs. Doolin was the bogeyman of Henry’s life. Ten years before, she had descended upon him and since that time . . .

  “Yes, Lizzie,” said Henry, aware for the first time of his stiffness and suddenly very tired.

  “Are you coming to dinner or aren’t you? I called you a half-hour ago and the beefsteak will be ruined. And you must dress. What on earth’s gotten into you, Henry Mudge?”

  “Yes, Lizzie,” said the doctor placatingly. He came slowly to his feet and his joints cracked loudly.

  “What have you done to this place?”

  Some of the fire of his enthusiasm swept back into Henry. “Lizzie, I think I have it!” And that thought swept even Lizzie Doolin out of the room as far as he was concerned. He took a few excited steps around the table, raised his glasses up on his forehead and gleamed. “I think I’ve got it!”

  “What?” demanded Lizzie Doolin.

  “The equation. Oh, this is wonderful. This is marvelous! Lizzie, if I am right, there is a condition without dimension. A negative dimension, Lizzie. Think of it! And all these years they have been trying to find the fourth positive dimension and now by working backwards . . .”

  “Henry Mudge, what are you talking about?”

  But Henry had dived into the abstract again and the lightning was flashing inside his head. “The negative dimension
! Epistemology!”

  “What?”

  He scarcely knew she was there. “Look, think of it! You know what you can do with your mind. Mentally you can think you are in Paris. Zip, your mind has mentally taken you to Paris! You can imagine yourself swimming in a river and zip! you are mentally swimming in a river. But the body stays where it is. And why, Lizzie? Why?”

  “Henry Mudge—!”

  “But there is a negative dimension. I am sure there is. I have almost formulated it and if I can succeed—”

  “Henry Mudge, your dinner is getting cold. Stop this nonsense. . . .”

  But he had not heard her. Suddenly he gripped his pen and wrote. And on that blotted piece of paper was set down Equation C.

  He was not even aware of any change in him. But half his brain began to stir like an uneasy beast. And then the other half began to stir and mutter.

  And on the sheet before him was Equation C.

  “Henry Mudge!” said Lizzie with great asperity. “If you don’t come in here and eat your dinner this very minute . . .” She advanced upon him as the elephant moves upon the dog.

  Henry knew in that instant that he had gone too far with her. And half his brain recognized the danger in her. For years he had been in deadly terror of her. . . .

  “I wish I was in Paris,” Henry shivered to himself, starting to back up.

  Whup!

  Cognac, m’sieu?” said the waiter.

  “Eh?” gaped Henry, glancing up from the sidewalk table. He could not take it in. People were hurrying along the Rue de la Paix, going home as the hour was very late. Some of the cafés were already closed.

  “Cognac o vin blanc, m’sieu?” insisted the waiter.

  “Really,” said Henry, “I don’t drink. I—Is this Paris?”

  “Of a certainty, m’sieu. Perhaps one has already had a sip too much?”

  “No, no! I don’t drink,” said Henry, frightened to be in such a position.

  The waiter began to count the saucers on the table. “Then m’sieu has done well for one who does not drink. Forty francs, m’sieu.”

  Henry guiltily reached into his pocket. But his ink-stained jacket was not his street coat. He had carpet slippers on his feet. His glasses fell down over his eyes. And his searching hands told him that he possessed not a dime.

  “Please,” said Henry, “I am out of funds. If you would let me—”

  “SO!” cried the waiter, suavity vanishing. “Then you will pay just the same! GENDARME! GENDARME!”

  “Oh,” shivered Henry and imagined himself in the peaceful security of his study.

  Whup!

  Lizzie was gaping at him. “Why . . . why, where . . . where did you go? Oh, it must be my eyes. I know it must be my eyes. Those fainting spells did mean something then. Yes, I am sure of it.” She glanced at the clock. “Look, you haven’t eaten dinner yet! You come right into the dining room this instant!”

  Meekly, but inwardly aghast, Henry tagged her into the dining room. She set a plate before him. He was not very hungry, but he managed to eat. He was greatly perplexed and upset. The negative dimension had been there after all. And there was certainly no difficulty stepping into it and out of it. Mind was everything, then, and body nothing. Or mind could control body. . . . Oh, it was very puzzling.

  “What are you dreaming about?” challenged Lizzie. “Get upstairs and get dressed. It’s seven this very minute!”

  Henry plodded out into the hall and up the stairs. He got to his room and saw that all his things were laid out.

  Oh, it was very puzzling, he told himself as he sat down on the edge of the bed. He started to remove one carpet slipper and then scowled in deep thought at the floor.

  Twenty minutes later Lizzie knocked at his door. “Henry, you’re late already!”

  He started guiltily. He had not even taken that slipper off. If Lizzie found him in here— She was starting to open the door.

  “I ought to be there this very minute,” thought Henry, envisioning the lecture hall.

  Whup!

  It startled him to see them filing in. He stood nervously on the platform, suddenly aware of his carpet slippers and ink-stained working jacket, the spot on his nose and his almost black hand. Nervously, he tried to edge back.

  The dean was there. “Why . . . why, Dr. Mudge. I didn’t see you come in.” The dean looked him up and down and frowned. “I hardly think that your present attire . . . ”

  Henry visualized the clothes laid out on his bed and started to cough an apology.

  “I . . . er . . .”

  Whup!

  What’s that, Henry?” said Lizzie. “My heavens, where are you?”

  “In here, Lizzie,” said Henry on the edge of his bed.

  She bustled into the room. “Why, you’re not dressed! Henry Mudge, I don’t know what is happening to your wits. You will keep everybody waiting at the university—”

  “Ohhh,” groaned Henry. But it was too late.

  Whup!

  My dear fellow,” said the dean, startled. “What . . . er . . . what happened to you? I was saying that I scarcely thought it proper—”

  “Please, I—” But that was as far as Henry got.

  Whup!

  I know it’s my eyes,” said Lizzie.

  “Stop!” wailed Henry. “Don’t say anything! Please don’t say anything. Please, please, please don’t say anything!”

  She was suddenly all concern. “Why, you’re pale, Henry. Don’t you feel well?”

  “No—I mean yes. I’m all right. But don’t suggest anything. I . . .” But how could he state it? He was frightened half to death by the sudden possibilities which presented themselves to him. All he had to do was visualize anything and that scene was the scene in which he found himself. All anybody had to do was suggest something and zip! there he was.

  At first it had been a little difficult, but the gigantic beast Thought had risen into full power.

  “You dress,” said Lizzie.

  But he was afraid to start disrobing. What if he thought—

  No, he must learn to control this. Somehow he had missed something. If he could get the entire equation straight and its solution, he would have the full answer. But Thought was drunk with power and would not be denied.

  Henry rushed past Mrs. Doolin and down the steps to his study. He quickly sat in his chair and gripped his pen with determination. There was Equation C. Now if he could solve the rest of it he would be all right. He only had to substitute certain values . . .

  Lizzie had followed him down. “Henry, I think you must be going crazy. Imagine keeping all those men waiting in the lecture hall—”

  Whup!

  Henry groaned and heard the dean say, “It was to be our pleasure this evening that we hear from Dr. Mudge on the subject—”

  Somebody twitched at the dean’s sleeve. “He’s right beside you.”

  The dean looked and there was Henry, tweed jacket, ink stains, carpet slippers and all. Beads of perspiration were standing out on Henry’s bulging forehead.

  “Go right ahead,” whispered the dean. “I do not approve of your attire, but it is too late now.”

  Henry stood up, fiery red and choked with stage fright. He looked down across the amused sea of faces and cleared his throat. The hall quieted slowly.

  “Gentlemen,” said Henry, “I have made a most alarming discovery. Forgive me for so appearing before you, but it could not be helped. Mankind has long expected the existence of a state of mind wherein it might be possible to follow thought. However—” His lecture presence broke as he recalled his carpet slippers. Voice nervous and key-jumpy, he rushed on. “However, the arrival at actual transposition of person by thought alone was never attained because mankind has been searching forward instead of
backward. That is, mankind has been looking for the existence of nothing in the fourth dimension instead of the existence—” He tried to make his mind clear. Stage fright was making him become involved. “I mean to say, the negative dimension is not the fourth dimension but no dimension. The existence of nothing as . . .”

  Some of the staid gentlemen in the front row were not so staid. They were trying not to laugh because the rest of the hall was silent.

  “What idiocy is that man babbling?” said the dean to the university president behind his hand.

  Dr. Mudge’s knees were shaking. Somebody tittered openly in the fourth row.

  “I mean,” plunged Mudge, desperately, “that when a man imagines himself elsewhere, his mind seems to really be elsewhere for the moment. The yogi takes several means of accomplishing this, evidently long practiced in the negative dimension. Several great thinkers such as Buddha have been able to appear bodily at a distance when they weren’t there but . . .” he swallowed again, “but elsewhere when they were there. The metaphysicist has attributed supernatural qualities to the phenomenon known as an ‘apport,’ in which people and such appear in one room without going through a door when they were in the other room. . . .”

  Dear me, he thought to himself, this is a dreadful muddle. He could feel the truth behind his words, but he was too acutely aware of a stained jacket and carpet slippers and he kept propping up his glasses.

  “If a man should wish to be in some other place, it is entirely possible for him to imagine himself in that place, and, diving back through the negative dimension, to emerge out of it in that place with instantaneous rapidity. To imagine oneself—”

  He swallowed hard. An awful thought had hit him, big enough to make him forget his clothes and audience. A man could imagine himself anyplace and then be in that place, zip! But how could a man exert enough willpower to keep from imagining himself in a position of imminent destruction? If he thought— Mudge gritted his teeth. He must not think any such thing. He must not! He knew instinctively that there was one place he could not imagine himself without dying instantly before he could recover and retreat. He did not know the name of that place in the instant, would not allow himself to think of it—
