+
+[Sidenote: In their pursuit of an unscrupulous scientist, Phil and
+Ione are swung into hyperspace--marooned in a realm of strange sights
+and shapes.]
+
+
+Tony Costello leaned glumly over his neat, glass-topped desk, on which
+a few papers lay arranged in orderly piles. Tony was very blue and
+discouraged. The foundations of a pleasant and profitable existence
+had been cut right out from under him. Gone were the days in which the
+big racket boss, Scarneck Ed, generously rewarded the exercise of
+Tony's brilliant talents as an engineer in redesigning cars to give
+higher speed for bootlegging purposes, in devising automatic electric
+apparatus for handling and concealing liquor, in designing
+beam-directed radios for secret communication among the gangs. Yes,
+mused Tony, it had been profitable.
+
+Six months ago the Citizens' Committee had stepped in. Now the police
+department was reorganized; Scarneck Ed Podkowski was in jail, and his
+corps of trusty lieutenants were either behind the bars with him or
+scattered far and wide in flight. Tony, always a free spender, had
+nothing left but the marvelous laboratory and workshop that Scarneck
+Ed had built him, and his freedom. For the police could find nothing
+legal against Tony. They had been compelled to let him alone, though
+they were keeping a close watch on him. Tony's brow was as dark as the
+mahogany of his desk. He did not know just how to go about making an
+honest living.
+
+With a hand that seemed limp with discouragement, he reached into his
+pocket for his cigarette-case. As he drew it out, the lackadaisical
+fingers failed to hold it firmly enough, and it clattered to the floor
+behind his chair. With the weary slowness of despondence, he dragged
+himself to his feet and went behind his chair to pick up the
+cigarette-case. But, before he bent over it, and while he was looking
+fully and directly at it, his desk suddenly vanished. One moment it
+was there, a huge ornament of mahogany and glass; the next moment
+there was nothing.
+
+ * * * * *
+
+Tony suddenly went rigid and stared at the empty space where his desk
+had stood. He put his hand to his forehead, wondering if his financial
+troubles were affecting his reason. By that time, another desk stood
+in the place.
+
+Tony ran over this strange circumstance mentally. His mental processes
+were active beneath, though dazed on the surface. His desk had stood
+there. While looking fully at it, all his senses intact, he had seen
+it vanish, and for a moment there had been nothing in its place. While
+he stared directly at the empty space from which the desk had
+disappeared, another desk had materialized there, like a flash.
+Perhaps, there had been a sort of jar, a tremor, of the floor and of
+the air, of everything. But the point was that his own desk, at which
+he had been working one moment, had suddenly vanished, and at the next
+moment another desk had appeared in its place.
+
+And what a desk! The one that now stood there was smaller than his own
+palatial one, and shabbier. A raw, unpleasant golden-oak, much
+scratched and scuffed. Its top was heaped and piled full of books and
+papers. In the middle of it stood a photograph of a girl, framed in
+red leather. Irresistibly, the sunny beauty of the face, the bright
+eyes, the firm little chin, the tall forehead topped by a shining mass
+of light curly hair, drew Tony's first glance. For a few moments his
+eyes rested delightedly on the picture.
+
+In a moment, however, Tony noticed that the books and papers on the
+desk were of a scientific character; and such is the nature of
+professional interest, that for the time he forgot his astonishment at
+how the desk had got there, in his absorption in the things heaped on
+top of it.
+
+Perhaps it isn't fair to give the impression that the desk was in
+disorder. It was merely busy; just as though someone who had been
+deeply engaged in working had for the moment stepped away. There was a
+row of books across the back edge, and Tony leaned over eagerly to
+glance at the titles.
+
+"'Theory of Parallels,' Lobatchevsky; 'Transformation of Complex
+Functions,' Riemann; 'Tensors and Geodesics,' Gauss," Tony read.
+"Hm--old stuff. But here's modern dope along the same line. 'Tensors,'
+by Christoffel; 'Absolute Differential Calculus,' by Ricci and Levi
+Civita. And Schrödinger and Eddington and D'Abro. Looks like
+somebody's interested in Relativity. Hm!"
+
+ * * * * *
+
+He bent over, his constantly increasing interest showing in the
+attitude of his body; he turned over papers and opened notebooks
+crowded full of handwritten figures. Last of all he noted the batch of
+manuscript directly in front of him in the middle of the front edge of
+the desk. It was typewritten, with corrections and interlineations all
+over it in purple ink.
+
+A title, "The Parallel Transformations of Equations for Matter,
+Energy, and Tensors," had been crossed out with purple ink, and "The
+Intimate Relation between Matter and Tensors" substituted. Tony bent
+over it and read. He was so fascinated that it did not even occur to
+him to speculate on the happy circumstance that the mysteriously
+appearing desk had brought its own scientific explanation with it. The
+title of the paper told him that its sheets would elucidate the
+apparently supernatural phenomenon, and all he did was to plunge
+breathlessly ahead in his eager reading. The article was short, about
+seven typewritten sheets. He took out his pencil and followed through
+the mathematical equations readily. Tony's mind was a brilliant, even
+though an erring one.
+
+Under the first article lay a second one. One glance at the title
+caused Tony to stiffen. Then he picked up the typewritten script and
+carried it across the big room of his laboratory, as far away from the
+desk as he could get. He put the girl's photograph in his pocket. Then
+he took heaps and armfuls of papers, books and notes and carried them
+from the desk to a bench in the far corner. For, as soon as he had
+read the title, "A Preliminary Report of Experimental Work in the
+Physical Manipulation of Tensors," a sudden icy panic gripped his
+heart lest the desk and its papers suddenly disappear before he had
+finished reading to the end of the fascinating explanation.
+
+We might add that it did not. For many weeks the desk remained
+standing in Tony's shop and laboratory, and he had the opportunity to
+study its contents thoroughly. But it took him only a few hours to
+grasp its secret, to add his own brilliant conception to it, and to
+form his great resolve. Once more Tony faced the world hopefully and
+enthusiastically.
+
+
+PART II
+
+_Vanishing Valuables_
+
+The police understood Tony's share in the exploits of Scarneck Ed
+thoroughly, and, chagrined at their failure to produce proof that
+would hold in court, they maintained a close and constant watch on
+that gifted gentleman long after crime matters in the city seemed to
+have been cleaned up and forgotten. For one thing, they still had
+hopes that something would turn up to enable them to round off their
+work and lock him up with his former pals; for another, they did not
+fully trust his future behavior. Nevertheless, for three or four
+months it seemed as though Tony had genuinely reformed. He lived in
+and for his laboratory and shop. All day the scouts could see him
+laboring therein, and far into the night he bent over benches and
+machines under shaded lights. Then, some other astonishing occurrences
+distracted their attention from Tony to other fields.
+
+One morning Mr. Ambrose Parakeet, private jewel broker, walked briskly
+out of the elevator on the fourteenth floor of the North American
+Building and unlocked the door of his office. He flung it open and
+started in, but stopped as if shot, uttered a queer, hoarse gurgle,
+and staggered against the door-casing. In a moment he recovered and
+began to shout:
+
+"Help! Help! Robbers!"
+
+Before long, several people had gathered. He stood there, gasping,
+pointing with his hand into the room. The eagerly peering onlookers
+could see that beside his desk stood an empty crate. It was somewhat
+old and weatherbeaten and looked as though it might have come from a
+buffet or a bookcase. He stood there and pointed at it and gasped, and
+the gathering crowd in the corridor wondered what sort of strange
+mental malady he had been seized with. The elevator girl, with trained
+promptness had at once summoned the manager of the building, who
+elbowed his way through the crowd and stood beside Mr. Parakeet.
+
+ * * * * *
+
+"There! There! Look! Where is it?" Mr. Parakeet was gasping slowly and
+gazing round in a circle. He was a little gray man of about sixty, and
+seemed utterly dazed and overcome.
+
+"What's wrong, Mr. Parakeet?" asked the building manager. "I didn't
+know you had your safe moved out."
+
+"But, no!" panted the bewildered old man. "I didn't. It's gone. Just
+gone. Last night at five o'clock I locked the office, and it was
+there, and everything was straight. What did you do? Who took it?"
+
+The building manager conducted the poor old man into the office, shut
+the door, and asked the crowd to disperse. He sat Mr. Parakeet down
+into the most comfortable chair he could find, and then barked
+snappily into the telephone a few times. Then he sat and stared about
+him, stopping occasionally to reassure the old man and ask him to be
+patient until things could be investigated.
+
+The building manager was an efficient man and knew his building and
+his tenants. He knew, as thoroughly as he knew his own office, that
+Mr. Parakeet had a medium-sized A. V. & L. Co.'s safe weighing about
+three tons, that could not be carried up the elevator when Mr.
+Parakeet had moved in, and had been hoisted into the window with block
+and tackle. He knew that it was physically impossible for the safe to
+go down any of the elevators, and knew that none of the operators
+would dare move any kind of a safe without his permission.
+Nevertheless, with the aid of a police-sergeant, his night-shift, and
+the night-watchmen of his building and adjacent ones, it was
+definitely established that nothing had been moved in or out of the
+North American Building during the preceding twenty-four hours, either
+by elevator or through a window to the sidewalk.
+
+ * * * * *
+
+The newspapers took up the mystery with a shout. The prostrating loss
+suffered by Mr. Parakeet, amounting to over a hundred thousand
+dollars, added no little sensation to the story. A huge safe,
+disappearing into thin air, without a trace, and in its place an old
+wooden crate! What a mouthful for the scareheads! For several days
+newspapers kept up items about it, dwindling in size and strategic
+importance of position; for nothing further was ever found. Every bit
+of investigation, including that by scientific men from the University
+of Chicago, was futile; not a trace, not a suggestion did it yield.
+
+Six days later the tall scareheads leaped out again: "Another Safe
+Disappears! Absolutely No Trace! Some time during the night, the
+six-foot steel safe of the Simonson Loan Company vanished into thin
+air. In the morning a dilapidated iron oil-cask was found in its
+place. The safe was so large and heavy that it could not have been
+moved without a large truck, special hoisting apparatus, a crew of
+men, and some hours of time. The store was brightly lighted during the
+entire night, and two watchmen patrolled it regularly. They report
+that they saw and heard nothing unusual, and were very much amazed
+when shown the oil-cask standing where the safe had been the night
+before." The accounts in the various papers were substantially the
+same.
+
+Newspaper readers throughout the city and its environs were very much
+intrigued. Such a thing was very exciting and mystifying; but it was
+so far out of touch with their own lives that it did not affect them
+very much at any time except when they were reading the paper or
+discussing it in conversation. The police were the ones who were doing
+the real worrying. And, when the following week two more safes
+disappeared, insurance companies began to take an interest in the
+matter; and everyone who had any considerable amount of valuables in
+store began to feel panicky.
+
+ * * * * *
+
+The circumstances surrounding the disappearance of the last of the
+series, the fourth, were especially amazing. This was also a jewelry
+safe. Canzoni's is a popular firm that rents a quarter of a floor in a
+big department store, and does a large volume of moderate-priced
+business. The receipts are stored in a heavy portable safe in a corner
+of the silverware section until evening, when they are carried to the
+large vault of the big store. One Saturday afternoon after a
+particularly busy day, Mr. Shipley, Canzoni's manager, was watching
+the hands of the clock creep toward five-thirty. He leaned on a
+counter and watched the clerks putting away goods for the night; he
+glanced idly toward the safe which he intended to open in a few
+minutes. The doormen had already taken their stations to keep out
+further customers. Then he glanced back at the safe, and it wasn't
+there!
+
+Mr. Shipley drew a deep breath. The safe disappearances he had read
+about flashed through his mind. But he didn't believe it. It couldn't
+be! Yet, there was the empty corner with the birch panels forming the
+back of the show-windows, and no safe. In a daze, he walked over to
+the corner, intending to feel about with his hands and make sure the
+safe was really gone. Before he got there, there flashed into sight in
+place of the safe, a barrel of dark wood; and in a moment there was a
+strong odor of vinegar.
+
+Things spun around with Mr. Shipley for a few moments. He grasped a
+counter and looked wildly about him. Clerks were hurrying with the
+covering of counters; no one seemed to have noticed anything. He stood
+a moment, gritted his teeth, and breathed deeply, and soon was master
+of himself. He stood and waited until the last customer was gone, and
+then called several clerks and pointed to where the safe had stood.
+
+Within the space of a month, thirteen safes and three million dollars
+worth of money or property had disappeared. The police were dazed and
+desperate, and business was in a panic. Scientific men were appealed
+to, to help solve the riddle, but were helpless. Many of them agreed
+that though in theory such things were explainable, science was as yet
+far from any known means of bringing them about in actuality.
+Insurance companies spent fabulous sums on investigation, and, failing
+to get results, raised their premiums to impossible levels.
+
+
+PART III
+
+_The Lady of the Picture_
+
+Phil Hurren, often known as "Zip" Hurren, reporter on the _Examiner_,
+felt, on the day the managing editor called him into the sanctum, that
+fortune could smile on him no more brightly. There wasn't anything
+brighter.
+
+"You stand well with the detective bureau," his boss had said; "and
+you've followed this safe-disappearing stuff pretty closely. You're
+relieved of everything else for the time being. Get on that business,
+and see that the public hears from the _Examiner_!"
+
+Phil knew better than to say any more, for before he recovered from
+his surprise, the editor had turned his back, buried himself in his
+work on the desk, and forgotten that Phil was there. Nor did Phil
+waste any real time in rejoicing. That is why he was called "Zip."
+When things happened, whether it was luck or system, Phil was usually
+there. In sixty seconds more, Phil was in a taxicab, whirling toward
+police headquarters.
+
+Luck or system, he didn't know, but he struck it again. The big wagon
+was just starting away from the station door when he arrived, crowded
+inside with bluecoats and plainclothes-men. The burly, red-faced man
+with chevrons on his sleeve, sitting beside the driver, saw Phil jump
+out, and motioned with his hand. Phil leaped up on the back step of
+the vehicle and hung on for dear life with his fingers through the
+wire grating as they careened through the streets. The men on the
+inside grinned at him; a number of them knew him and liked him.
+Gradually the door was opened and he crowded in. He found Sergeant
+Johnson and eyed him mutely.
+
+"How the hell do you find these things out, I'd like to know," the
+sergeant exclaimed. "Are you a mind-reader?"
+
+"I don't really know anything," Phil admitted with that humility which
+the police like on the part of newspaper men and seldom meet with. "Do
+you mind?"
+
+"No objection," grunted the sergeant. "Been watching all the old
+crooks since these safes have been popping. Nothin' much on any of
+them, except this slippery wop, Tony Costello. No, we haven't caught
+him at anything. Seems to be keeping close and minding his own
+business. Working in his laboratory. Ought to make a good living if he
+turned honest; clever guy, he seems. But he's been too prosperous
+lately. Lots of machinery delivered to his place; we traced it to the
+manufacturers and find it cost thousands. Big deposits in his banks.
+But, no trace of his having sold anything or worked at anything
+outside his own place. So, we're running over to surprise him and help
+him get the cobwebs out of his closets."
+
+ * * * * *
+
+The raid on Tony Costello's shop and laboratory disclosed nothing
+whatever. They surrounded the place effectively and surprised Tony
+genuinely. But a thorough search of every nook and cranny revealed
+nothing whatever of a suspicious nature. There was merely a tremendous
+amount of apparatus and machinery that none of the raiding party
+understood anything about. Tony's person was also thoroughly searched,
+and the leather-framed photograph of the beautiful unknown girl was
+found.
+
+"Who's this?" the sergeant demanded. "She don't look like anyone that
+might belong to your crowd."
+
+"I don't know," Tony replied.
+
+"Whad'ya mean, don't know?" The sergeant gave him a rough shake.
+"What'ya carryin' it for, then?"
+
+"I had really forgotten that it was in my pocket," Tony replied
+calmly, at his ease. "I found it in a hotel room one day, and liked
+the looks of it."
+
+"I know you're lying there," the sergeant said, "though I'm ready to
+believe that you don't know her. Too high up for you. Well, it looks
+suspicious and we'll take the picture."
+
+"Boy!" gasped Phil. "What a girl she must be in person! Even the
+picture would stand out among a thousand. May I have the picture,
+Sergeant?"
+
+"You can come and get a copy of it to-morrow. We'll have it copied and
+see if we can trace the subject of it. That might tell us something."
+
+ * * * * *
+
+The following morning Phil was at Police Headquarters to pick up
+further information, and to get a copy of the girl's photograph. Like
+the police, he could not keep his mind off the idea that there was
+some association between the crooked engineer and the disappearance of
+the safes. It seemed to fit too well. The scientific nature of the
+phenomena, Tony Costello's well known reputation for scientific
+brilliance, and his recent affluence; what else could it mean? In some
+way, Tony was getting at these safes. But how? And how prove it? Most
+exhaustive searches failed to reveal any traces of the safes anywhere.
+If any fragment of one of them had appeared in New York or San
+Francisco, the news would have come at once, such was the sensation
+all over the country that the series of disappearances had caused.
+Tony's calm insolence during the raid, his attitude of waiting
+patiently till the police should have had their fun and have it over
+with so that he might be left at peace again, showed that he must be
+guilty, for anyone else would have protested and felt deeply injured
+and insulted. He seemed to be enjoying their discomfiture, and
+absolutely confident of his own safety.
+
+"There's got to be some way of getting him," Phil mused; and he mused
+almost absent-mindedly, for he was gazing at the photograph of the
+girl. For many minutes he looked at it, and then put it silently into
+his pocket.
+
+Five o'clock in the evening of that same day came the news of another
+safe disappearance. Phil got his tip over the phone, and in fifteen
+minutes was at the scene. It was too much like the others to go into
+detail about; a six-foot portable safe had suddenly disappeared right
+in front of the eyes of the office staff of The Epicure, a huge
+restaurant and cafeteria that fed five thousand people three times a
+day. In its place stood a ragged, rusty old Ford coupe body. He went
+away from there, shaking his head.
+
+Then suddenly in the midst of his dinner, he jumped up, and ran. An
+idea had leaped into his head.
+
+"Right after one of these things pops is the time to take a peek at
+Tony," he said to himself, and immediately he was on the way.
+
+ * * * * *
+
+But how to get his peep was not so easy a problem. When he alighted
+from his cab a block away from Tony's building, he was hesitant about
+approaching it. Tony knew him, and might see him first. Phil circled
+the brick building, keeping under cover or far enough away; all around
+it was a belt of thirty feet of lawn between the building and the
+sidewalk. Ought he have called the police and given them his idea? Or
+should he wait till darkness and see what he could do alone?
+
+Then suddenly he saw her. Across the street, standing in the shelter
+of a delivery truck in front of an apartment, she was observing Tony's
+building intently. The aristocratic chin, the brightness of the eyes,
+the waves of her hair, and the general sunny expression! It could not
+be anyone else. Post haste he ran across the street.
+
+"Pardon me!" he cried excitedly, lifting his hat and then digging
+hastily into his inner pocket. "I'm sure you must be the--"
+
+"Well, the nerve!" the young woman said icily, and pointing her chin
+at the opposite horizon she walked haughtily away.
+
+By that time Phil had dug out his picture and was running after her.
+
+"Please," he said, "just a moment!" And he held the picture out in
+front of her face.
+
+"Now, where in the world--?" She looked at him in puzzled and
+indignant inquiry, and then burst out laughing.
+
+"It _is_ you, isn't it?" Phil asked. "What are you laughing at?"
+
+"Oh, you looked so abject. I'm sure your intentions must be good. Now
+tell me where you got my picture."
+
+"Let us walk this way," suggested Phil, leading away from Tony's
+building.
+
+ * * * * *
+
+And, as they walked, he told her the story. When he got through she
+stood and looked at him a long time in silence.
+
+"You look square to me," she said. "You're working on my side already.
+Will you help me."
+
+"I'll do anything--anything--" Phil said, and couldn't think of any
+other way of expressing his willingness, for the wonderful eyes bore
+radiantly upon him.
+
+"First I must tell you my story," she began. "But before I can do so,
+you must promise me that it is to remain an absolute secret. You're a
+newspaper man--"
+
+Phil gave his promise readily.
+
+"My father is Professor Bloomsbury at the University of Chicago. He
+has been experimenting in mathematical physics, and I have been
+assisting him. He has succeeded in proving experimentally the concept
+of tensors. A tensor is a mathematical expression for the fact that
+space is smooth and flat, in three dimensions, only at an infinite
+distance from matter; in the neighborhood of a particle of matter,
+there is a pucker or a wrinkle in space. My father has found that by
+suddenly removing a portion of matter from out of space, the pucker
+flattens out. If the matter is heavy enough and its removal sudden
+enough, there is a violent disturbance of space. By planning all the
+steps carefully my father has succeeded in swinging a section of
+space on a pivot through an angle of 180 degrees, and causing two
+portions of space to change places through hyperspace, or as you might
+express it popularly, through the fourth dimension."
+
+ * * * * *
+
+Phil held his hands to his head.
+
+"It is not difficult," she went on smiling. "Loan me your pocket knife
+and a piece of paper from your notebook. If I cut out a rectangular
+piece of paper from this sheet and mount it on a pivot or shaft at A
+B, I can rotate it through 180 degrees, just like a child's
+teeter-totter, so that X will be where Y originally was. That is in
+two dimensions. Now, simply add one dimension all the way round and
+you will have what daddy is doing with space. He does it by shoving
+fifty or a hundred pounds of lead right out of space; the sudden
+flattening out of the tensors causes a section of space to flop
+around, and two portions of space change places. The first time he
+tried it, his desk disappeared, and we've never seen it again. We've
+thought it was somewhere out in hyperspace; but this terrible story of
+yours about disappearing safes, and the fact that you have this
+picture, means that someone has got the desk."
+
+"Surely you must have suspected that long ago, when the disappearances
+first began?" Phil suggested.
+
+"I've just returned from Europe," said Miss Bloomsbury. "I was
+tremendously puzzled when I got my first newspapers in New York and
+read about the safes. Gradually I gathered all the news on the
+subject, and it seemed most reasonable to suspect this gangster
+engineer."
+
+"Great minds and same channels," Phil smiled. "But your father. Why
+didn't he speak up when the safes began to pop?"
+
+"Ha! ha!" she laughed a tinkly little laugh. "My father doesn't know
+what safes are for, nor who is President, nor that there has been a
+war. Mother and I take care of him, and he works on tensors. He has
+probably never heard about the safes."
+
+ * * * * *
+
+"What were you going to do around here?" Phil asked, marveling at the
+courage of the girl who had come to look the situation over
+personally.
+
+"I hadn't formed any definite plans. I just wanted to look about
+first."
+
+"Well," said Phil, "as you will soon see by the papers, another safe
+has puffed out. It occurred to me that we might find out something by
+spying about here immediately after one of the disappearances. That's
+why I'm here. If you'll tell me where you live, or wait for me at some
+safe place, I'll come and report to you as soon as I find out
+anything."
+
+"Oho! So that's the kind of a girl you think I am!" She laughed
+sunnily again. "No, Mr. Reporter. Either we reconnoiter together, or
+each on our own."
+
+"Oh, together, by all means," said Phil so earnestly that she laughed
+again. "And since we'd better wait for darkness, let's have something
+to eat somewhere. I didn't finish my dinner."
+
+Phil found Ione Bloomsbury in person to be even more wonderful than
+her photograph suggested. Obviously she had brains; it was apparent,
+too that she had breeding. Her cheerful view of the world was like a
+tonic for tired nerves; and withal, she had a gentle sort of courtesy
+in her manner that may have been old-fashioned, but it was almost too
+much for Phil. Before the dinner was over, he would have laid his
+heart at her feet. It gave him a thrill that went to his head, to have
+her by his side, slipping along through the darkness toward Tony's
+building.
+
+This building was a one-story brick affair with a vast amount of
+window space. From the sidewalk they could see faint lights glowing
+within, but could make out no further details. They therefore selected
+the darkest side of the building, and made their way hurriedly across
+the lawn. Here, they found, they could see the crowding apparatus
+within the one long room fairly well. They looked into one window
+after another, making a circuit around the building, until Phil
+suddenly clutched the girl's arm.
+
+"Look!" he whispered. "Straight ahead and a little to the left!"
+
+At the place he indicated stood a tall safe. Across the top of its
+door were painted in gold letters, the words: "The Epicure."
+
+"That's the safe that went to-night," whispered Phil. "That's all we
+need to know. Now, quick to a telephone!"
+
+"Oh," said a gentle, ironic voice behind them, "not so quick!"
+
+ * * * * *
+
+They whirled around and found themselves looking into two automatic
+pistols, and behind them in the light of the street lamps, the
+sardonic smile of Tony Costello.
+
+"Charmed at your kind interest in my playthings, I'm sure," he purred.
+"Only it leaves me in an embarrassing position. I'm not exactly sure
+what to do about it. Kindly step inside while I think."
+
+Phil made a move sidewise along the wall.
+
+"Stop!" barked Costello sharply. "Of course," his voice was quiet
+again, "that might be the simplest way out. I think I am within my
+legal rights if I shoot people who are trying to break into my
+property. Yet, that would be messy--not neat. Better step in. The
+window swings outward."
+
+At the point of his pistols they clambered through the window, and he
+came in after them. He kept on talking, as though to himself, but loud
+enough for them to hear.
+
+"Yes, we want some way out that is neater than that. Hm! Violence
+distresses me. Never liked Ed's rough methods. Yet, this is
+embarrassing."
+
+He turned to them.
+
+"What did you really want here? I see that you are the _Examiner's_
+reporter, and that you are the lady of the photograph. What did you
+come here for? Ah, yes, the safe. Well, go over and look at it."
+
+As they hesitated, he stamped his foot and shrilled crankily:
+
+"I mean it! Go, look at the safe! Is there anything else you want to
+know?"
+
+"Yes," said Phil coolly, his self-control returning, "where are the
+other safes?"
+
+"Oh. Anything to oblige. Last requests are a sort of point of honor,
+aren't they. Ought to grant them. Stand close to that safe!"
+
+ * * * * *
+
+He backed away, his guns levelled at them. He laid down the right one,
+keeping the left one aimed, and moved some knobs on a dial and threw
+over a big switch. A muffled rumbling and whirring began somewhere;
+and then, slowly, a block of tables and apparatus ten feet square rose
+upward toward the ceiling. A section of the floor on which they stood
+came up, supported by columns, and now formed the roof of a room that
+had risen out of the floor. In it were four safes.
+
+"Poor old Ed!" sighed Tony. "There was a time when he had a lot of
+good stuff put away down there. I've got six rooms like that. Well,
+the good old times are over."
+
+He threw out the switch and the whole mass sank slowly and silently
+downward till the floor was level and there was no further sign of it.
+Then he backed away to another table, across the room from them,
+keeping his gun levelled.
+
+"Too bad," he said. "I don't like to do these things. But--" he sighed
+deeply, "self-preservation. Now I'm going to flip you out, yes,
+_out_, into a strange region. I've never been there. I don't know if
+there is food or drink there. I hope so, for you'll never get back
+here."
+
+Phil stiffened. He determined to leap and risk a shot. But he was too
+late. Tony's hand came down on a switch. There was a sudden,
+nauseating jar. The laboratory vanished.
+
+There was only the safe, Ione Bloomsbury and himself, and a small
+circle of concrete floor extending to a dim little horizon a dozen
+feet away. Beyond that, nothing. Not blue, as the sky is. Not black,
+as dark, empty spaces are. It suggested black, because there was no
+impression of light or color on the eyes; but it wasn't black. It was
+nothingness.
+
+
+PART IV
+
+_Marooned in Hyperspace_
+
+"I suppose you realize what he has done?" Miss Bloomsbury inquired.
+
+"Couldn't be too sure, but it looks like plenty. What's the equation
+for it?" Beneath his jocularity, Phil felt a tremendous sinking within
+him. It looked serious, despite the fact that he did not understand it
+at all.
+
+"He has swung us out into hyperspace, or into the fourth dimension, as
+your newspaper readers might understand it, and has let us hang there.
+Remember our slip of paper. Suppose X and Y were swung out of the
+plane of the paper and allowed to remain at an angle with it. We are
+at an angle with space, out in hyperspace."
+
+There was a period of bewilderment, almost panic, in which they both
+felt so physically weak that they had to sit down on the concrete and
+stare at each other mutely. But this passed and their natural courage
+soon reasserted itself. Their first thought was to take stock of what
+information they could get on their situation; and their first step
+was to venture as close as possible to the queer little horizon which
+lay almost at their very feet. It gave them a frightened feeling, as
+though they were standing high up on a precipice or tower.
+
+To their surprise, the horizon receded as they walked toward it,
+always remaining about a dozen feet away from them. At first they
+walked on concrete and then came to a crumbly edge of it and found
+themselves stepping on hard, sandy earth. Later there was rock,
+sometimes granite-like, sometimes black and shiny. But what they saw
+underfoot was nothing, compared with the glimpses of things they got
+out in the surrounding emptiness. First there was a vast space in
+which a soft light shone, and in which there were countless spheres of
+various sizes, motionlessly suspended. The spheres seemed to be made
+of wood, a green, sap-filled, unseasoned wood. The scene was visible
+for a few seconds, and vanished suddenly as they walked on. This
+astonished them; so they stepped back a pace or two and saw it again;
+and as they moved on, it disappeared again.
+
+ * * * * *
+
+Then there was a great stretch of water in which the backs of huge
+monsters rolled and from which a hot wind blew for a few instants
+until they passed on and the scene vanished. There was a short walk
+with nothing but emptiness, and then there appeared huge, oblique,
+cubistic looking rows of jagged rocks in wild, dizzy formations that
+didn't look possible; and farther on, after another interval of
+emptiness, a tangle of brown, ropey vines with black-green leaves on
+them, an immense space filled with serpentine swinging loops and
+lengths of innumerable vines. Several loops projected so near them
+that they could have reached out and touched them had they wished.
+
+"This is too much for me!" Phil gasped. "Have we gone crazy? Or did
+he kill us, and is this Purgatory?"
+
+Ione smiled and shook her little head in which she had a goodly store
+of modern mathematics stored away.
+
+"These must be glimpses of other 'spaces' besides our own space. If we
+could see in four dimensions we could see them all spread out before
+us. But we can only perceive in three dimensions; therefore, as we
+walk through hyperspace, past the different 'spaces' which are ranged
+about in it, we get a glimpse into such of them as are parallel with
+our own space. Can you understand that?"
+
+"Oh, yes," groaned Phil. "It sounds just about like it looks. But,
+don't mind me. Go on, have your fun."
+
+"I've been thinking about those wooden spheres," continued Ione. "I'm
+sure they must be sections of trees that are cut crosswise by our
+'space;' they grow in three dimensions, but only two of them are our
+dimensions and a third is strange to us. We see only three-dimensional
+sections of them, which are spheres. There is more of them, that we
+cannot see, in another dimension."
+
+"Yes, yes. Just as plain as the Jabberwock!"
+
+"Look! There's a real Jabberwock!" exclaimed Ione.
+
+On ahead of them they saw a number of creatures that seemed to be made
+of painted wooden balls in different colors, joined together.
+
+"Tinkertoys!" exclaimed Phil. "Live ones! Big ones!"
+
+The animals, though they looked for all the world as though they were
+made of painted wood, moved with jerky motions and clattered and
+snarled.
+
+"There is probably more to _them_ in another dimension," Ione said.
+
+ * * * * *
+
+Suddenly one of the beasts approached them with a leap. There were two
+big eyes and two rows of teeth that came together with a snap, right
+on Phil's trouser-leg. He jerked himself away, sacrificing some square
+inches of trouser-leg, and, whirling around, kicked at the thing with
+all his force. It almost paralyzed his foot, for the animal seemed to
+be made of wood or bone. But it disappeared, and, as it did, both of
+them felt a queer, nauseating jolt. A few more minutes' walk brought
+them back to the safe without seeing any more spaces; and the sight of
+its black iron bulk filled them with a home-like relief, which in a
+moment they recognized as a mockery.
+
+"Are we on a sphere of some sort?" Phil asked.
+
+"Probably on an irregular mass of matter," Ione replied, "part of
+which is Tony's concrete floor, and part of which comes out of some
+other dimension. This mass of matter is at one end of a long, bar-like
+portion of space, the middle of which is pivoted in our world,
+somewhere in Chicago, and both ends of which are free in hyperspace."
+
+"Then," suggested Phil, "why can't we walk down to the axle on which
+it is balanced, and step out into Chicago?"
+
+"Because there isn't any _matter_ for us to walk on. We are not able
+to move about in space, in three dimensions, you know. We can only get
+around in two dimensions, on the surface of _matter_."
+
+"Well, let's try another exploration trip at right angles to our first
+one. After all, these 'spaces' are an interesting show, and I want to
+see some more."
+
+They started out in the selected direction, and after a short walk got
+a glimpse of a vast space dotted with stars and nebulae, with two
+bright moons sailing overhead. A few steps farther on was a wall of
+solid granite, near enough to touch with their hands. Again, there was
+an intensely active mass of weaving bright stripes and loops and
+circles, seeming to consist of light only, and making them dizzy in a
+few seconds. Ione wondered if it might not be something like an
+organic molecule on a large scale. Again, odd, queer, indescribable
+shapes and outlines would appear and disappear, obviously
+three-dimensional sections of multi-dimensional things, cut by space.
+Once they passed a place of intense cold and terrific noise and
+escaped destruction or lunacy only because it took them the merest
+instant to get past.
+
+They arrived back at the safe, very much fatigued from the strain,
+their minds woefully confused. Hunger and thirst were beginning to
+thrust up their little reminders; and for the first time the terrors
+of their position, flung out into hyperspace on a small, barren piece
+of matter, began to seem real.
+
+ * * * * *
+
+After a rest they started out again. As Phil had touched, in kicking
+it, a creature from another "space," perhaps they might find water and
+even food somewhere. They retraced their first steps to the spot where
+they had at first seen water. They found it again and were able to dip
+their hands into it. It was warm, and too salty to drink. They came to
+the place with the creepers or vines, and Phil reached out and seized
+one of them. It was heavy, rubbery, and elastic, stretching readily as
+he pulled it.
+
+"These little lurches that we feel must be the snapping back of the
+space-puckers as expressed by tensors," Ione remarked. "Every time
+matter goes in or out of space, the nature of space is altered."
+
+"Well," observed Phil, releasing the vine, "I'd better be careful. If
+one of these things hauls me off here, our last bond with home is
+gone. I don't want to get lost in some other space."
+
+As he released the vines they snapped back to their places, and the
+forest of them dimmed a little and reappeared.
+
+They made the round again, dodging cautiously past the point where
+they had previously found the "Tinkertoy" animals, and succeeded in
+getting past their snapping teeth. But no promise of food or water did
+they find anywhere.
+
+"Looks like we're sunk," observed Phil, as they dropped down on the
+concrete to rest, leaning their backs against the safe.
+
+How time counted in hyperspace, neither Phil nor Ione could tell; Phil
+knew that his watch was running. He knew that it was ages and ages
+that he sat with his back against the safe, reviewing all the events
+of his put life, and thinking of this ignominious end to a lively
+career! He swore half aloud; then suddenly looked at Ione, ready to
+apologize. He found her weeping silently.
+
+"I should never have let you come into the building with me," he
+stammered in confusion at her tears.
+
+"Oh, what do I care what becomes of _me_!" she exclaimed angrily. "But
+who will take care of poor daddy? He doesn't even know when it's time
+to eat." And she burst into a fresh fit of weeping.
+
+Phil bent his head in the dumbness of profound despair.
+
+
+PART V
+
+_The Reversible Equation_
+
+Despair, however, is a luxury. Necessity is a stimulus. With the
+parchings of thirst and the gnawings of hunger, the two young people
+ceased swearing and weeping. Phil got up and paced about and sat down
+again. Ione's tears stopped and dried, and she sat and thought.
+
+In the back of her mind there had been forming a vague sort of an
+idea, which had signalled ahead of itself that there was hope. She sat
+there and desperately drove her reason to its utmost efforts, to find
+that idea and bring it to the surface of consciousness. Hand to hand
+fights with wild animals, battles between ships of the line, vicious
+duels between ace-aviators in the clouds are tense fights; but they
+cannot compare in anxious difficulty with the struggle to bring up an
+unformed idea out of the subconscious mind--especially when one knows
+that the idea is there, and that it must be found to save one's life.
+
+"Ione!" exclaimed Phil. It was the first time he had used the name.
+"What is the matter? You are as tense as a--"
+
+"Ah!" cried Ione, springing up. "Tense! Tensors! I have it!"
+
+Phil gazed at her in alarm. She laughed; at first it was a strained
+laugh, but gradually it melted into her sunny one.
+
+"No, I'm not crazy. I knew there was a way out, and I've been trying
+to reason it out. How simple. You remember the little jolts when you
+pulled at the vines and when you kicked the funny animal? Tensors.
+Matter and space are so closely interrelated that you can't move
+matter in or out of space without causing disturbance, recoils, and
+tremors in space. Those bits of matter were small, and produced only a
+slight disturbance. It takes about a hundred pounds of lead to swing
+this segment--"
+
+"Oho! Got you!" exclaimed Phil. "Not so dumb! The safe!"
+
+"Yes. The safe!" Ione cried.
+
+"Throw it off and watch us swing, eh? What would happen?"
+
+"I might calculate it if I knew the weight of the safe."
+
+"No calculating when I'm around," Phil said. "It couldn't make things
+any worse. Try it first and calculate afterwards."
+
+ * * * * *
+
+They got behind the safe and pushed, and their combined strength
+against it was about as effective as it would have been in moving the
+Peoples' Gas Building. They sat down again in despair.
+
+"Suppose we _could_ budge it," Ione said. "All we could do would be to
+push it around, this piece of matter we are on. That wouldn't help.
+We've got to get it out of space. We can't push it hard enough to do
+that. It's got to be shot out suddenly--"
+
+"And we haven't got a gun handy," Phil remarked droopingly.
+
+"Not exactly a gun. A sort of sling--"
+
+Phil leaped to his feet.
+
+"A sling. Why! To be sure! The vines!"
+
+Without another word, both of them got up and ran. They hastened in a
+direction opposite to the one they had at first taken on their trip of
+exploration, and this brought them first past the "space" of the
+Tinkertoy-like animals. As they went by, several of these beasts
+darted at them, one of them snapping at Ione's heels. She uttered a
+scream, causing Phil to turn about and kick right and left among them.
+He drove them back and escaped from them, rejoining Ione.
+
+"Wait," he said, when they reached the vines. "Remember those wooden
+balls. If I could get a few to throw at those critters--"
+
+In a moment they were off, and finally arrived at the point from which
+they first saw the balls. Odd it seemed, how they hung suspended in
+space, thousands of them, all sizes. Phil reached out and grasped one
+about the size of a baseball and drew it toward himself. He felt a
+dizzy lurch and heard Ione scream.
+
+"Let go!" she screamed again.
+
+When he suddenly realized what was going on, he found himself
+prostrate on the ground, with Ione across him, her arms about his
+knees.
+
+"Do you realize," she panted, disentangling herself, "that you were
+pulling yourself out of this space into that one?"
+
+"Thanks!" said Phil. "Never say die. More careful this time, and a
+smaller one."
+
+ * * * * *
+
+He reached out and grasped a ball smaller than a golf-ball, and pulled
+carefully, keeping an eye upon Ione. There was resistance to his pull,
+but gradually the ball came. It seemed heavy. There was a crack as of
+breaking wood, and he fell backward, with a wave of nausea sweeping
+strongly over him. He gazed in amazement at a heavy wooden stick that
+he held in his hands. The only thing about it that suggested the ball
+for which he had reached was its diameter.
+
+"Can't understand it, but appreciate it just the same," he said. He
+broke the stick in two, and had two excellent clubs.
+
+"Simple," Ione replied. "The balls are cross-sections of these trees
+or sticks which grow in a 'space' at right angles to our own; and we
+only see their three-dimensional cross-sections."
+
+"Yes," said Phil. "Cabbages and kings. I'm for you and the party."
+
+A short walk brought them to the "space" of the vines. After testing
+the matter out carefully, they found that they could each pull two of
+them at a time. The vines stretched amazingly when they found those
+whose far ends were fixed firmly in the tangle, permitting them to
+carry their own ends along with them toward the safe. Phil wound his
+vines around his left arm and stuck one club through his belt. The
+other he got ready for the wooden animals.
+
+He needed it. The size of the pack was doubled, and he rapped them
+till his hand was numb before he and Ione got by. Their vines drew out
+thin, but held until they were firmly tied about the safe. They went
+back after four more.
+
+"I should judge," said Phil, "that by the time we get thirty or forty,
+the elastic pull will be strong enough to drag the safe back with
+them as they snap back home."
+
+ * * * * *
+
+Trip after trip they made, fighting the wooden animals with their
+clubs each time. Their clothes were torn, and their legs bleeding;
+their throats were dry and lips cracked. The hard animals seemed to
+have a persistent, mechanical ferocity that was undismayed by
+hammering with the clubs and by repeated repulses. Phil could not seem
+to hurt them; he merely knocked them away. Finally, on the ninth trip,
+Ione collapsed when she reached the safe. As she fell, the elasticity
+of the vines began slowly to drag her back with them. Phil was forced
+to sit across her knees while he tied his own vines about the safe.
+Then he released her and added her vines to the great cable about the
+safe.
+
+An overbold hard animal rattled up and snapped at her. Goaded to fury,
+Phil swung at it with his club and hurled it through the air. He could
+feel the lurch as it left his space and entered another. Then he
+pushed with his mightiest effort against the safe. It budged, and slid
+a few inches. He used his stick as a lever. It moved again, a little
+faster. Ione struggled to her feet and tried to help, but her efforts
+were ineffectual.
+
+With one arm about her, Phil pried again under the safe, knowing that
+another trip after vines was out of question. Another animal snapped
+at their heels. For a while, it was kick backwards, then a shove at
+the safe. Each time the safe moved. The sight of its movement revived
+Ione, so that she was able to push also. Gradually it acquired a
+steady motion, pulled by the contraction of the vines; its progress
+soon became faster and faster. Phil was about to follow it and give it
+another push, when Ione drew him back.
+
+Suddenly they experienced a sinking sensation and a fearful vertigo.
+The snapping animals faded. Ahead of them was the forest of vines, and
+they saw the safe hurled into it, crashing, plunging into the tangled
+mass. The whole view crumpled and moved upwards like a swirl of leaves
+in a wind, and then vanished with a snap.
+
+ * * * * *
+
+They were sick and dizzy, but tremendously curious to see everything.
+The water, the cubistic cliffs, the vast space full of balls, all
+curiously blurred, appeared in succession. There were blank spaces and
+then blurred sights of things which they did not recognize, never
+having seen them before. Then the dizziness and the nausea abated, and
+ahead of them was a vast yellow blue, a huge nebula, and in it were
+double-colored suns and ringed planets with swarms of moons; this
+glorious sight remained for many seconds, as they gazed at it in
+panting astonishment, half reclining on the concrete; and then it
+faded. Again the nausea came on; again the succession of blurred
+views. Eventually the myriad spheres, the water with the leviathans,
+the forest of vines, each succeeding scene grew more blurred. Their
+nausea was correspondingly increased, till they were forced to lie
+down on the ground from illness.
+
+When their giddiness abated, there were blurring views again. There
+was an impression as though the speed of a train were decreasing as
+one looks out of the window. And how one view held for several
+seconds, a vast and wild mountain-range with glaciers and snow peaks
+by moonlight. When this faded gradually, the scenes began to flick by,
+more and more rapidly, and grew blurred. Phil and Ione were attacked
+by nausea until, again, they had to lie down. After that came the
+familiar succession: the wooden animals, the tangle of vines, the vast
+sea, the spheres, and more blurred scenes. Then came a pause, with
+the nebula and the glorious suns swinging into view once again.
+
+"Oh, I understand!" Ione exclaimed; "We're swinging. The safe was so
+heavy that we swung too violently, too far, and back again--"
+
+"And we keep going till it knocks us out, or till the old cat dies,"
+added Phil.
+
+ * * * * *
+
+However, they found that after a number of repetitions of the same
+program, their giddiness was becoming less; and instead of lying down
+in the middle of the swing, they could look about. Then it occurred to
+Phil to time the interval between the nebula and the mountain-range.
+When the exact halfway point was determined, and after several more
+swings, they could see dimly the windows and machinery of Tony's
+laboratory flash by when they passed the middle.
+
+"I don't mean to be a crepe-hanger, but how do you know we will stop
+at the right point?" Phil asked.
+
+"I don't," replied Ione cheerfully. "But mathematics says so. A freely
+oscillating segment of space would naturally come to equilibrium in a
+position parallel to the rest of its own space, would it not?"
+
+There came a swing when they did not reach the nebula on the one hand
+and the mountain-range on the other. After that, views dropped off
+from either end of the swing quite rapidly, and before many minutes,
+they looked into Tony's laboratory a large portion of the time. For
+many seconds the laboratory held; then it would gradually fade, and
+reappear again, only to fade into empty nothingness all around.
+
+"The old cat's dead," Phil finally announced.
+
+They sat and stared about them as the laboratory held steady and no
+further intervening periods of blankness intervened. They both sighed
+deeply and slumped over on the ground to rest.
+
+"Bang! bang! bang!"
+
+ * * * * *
+
+Some sort of hammering woke them up. They looked about them in a daze.
+It was broad daylight, and things looked queer in the laboratory.
+There was a smell of scorched rubber and hot oil. Great loops of wire
+sagged down from above. Several nondescript heaps stood about that
+might once have been machinery, but now suggested melting snow-men,
+all fused into heaps. At a table sprawled a queer, misshapen figure
+that suggested human origin. Both of its hands were burned to cinders
+to the elbows. Great holes were scorched into the clothes. But the
+face was recognizable. Tony's playthings had got him at last.
+
+"Looks like something's happened in here!" Phil gasped, in amazement.
+
+"I'll bet it has, too," Ione exclaimed. "This is the first time it
+occurred to me that our recoil from throwing the safe overboard and
+the oscillation of our space-segment must have created a tremendous
+electrical field in the tetra-ordinate apparatus. The reaction is
+reversible, you see. The field swings the space-segment, or the
+swinging of the space-segment creates the field. And the field was too
+much for Tony."
+
+At this point the door fell under the blows of the police, and the
+raiding squad rushed into the room.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+Ione are swung into hyperspace&mdash;marooned in a realm of strange sights
+and shapes.</div>
+
+
+<p><span class="f2">T</span>ony Costello leaned glumly over his neat, glass-topped desk, on which
+a few papers lay arranged in orderly piles. Tony was very blue and
+discouraged. The foundations of a pleasant and profitable existence
+had been cut right out from under him. Gone were the days in which the
+big racket boss, Scarneck Ed, generously rewarded the exercise of
+Tony's brilliant talents as an engineer in redesigning cars to give
+higher speed for bootlegging purposes, in devising automatic electric
+apparatus for handling and concealing liquor, in designing
+beam-directed radios for secret communication among the gangs. Yes,
+mused Tony, it had been profitable.</p>
+
+<p>Six months ago the Citizens' Committee had stepped in. Now the police
+department was reorganized; Scarneck Ed Podkowski was in jail, and his
+corps of trusty lieutenants were either behind the bars with him or
+scattered far and wide in flight. Tony, always a free spender, had
+nothing left but the marvelous laboratory and workshop that Scarneck
+Ed had built him, and his freedom. For the police could find nothing
+legal against Tony. They had been compelled to let him alone, though
+they were keeping a close watch on him. Tony's brow was as dark as the
+mahogany of his desk. He did not know just how to go about making an
+honest living.</p>
+
+<p>With a hand that seemed limp with discouragement, he reached into his
+pocket for his cigarette-case. As he drew it out, the lackadaisical
+fingers failed to hold it firmly enough, and it clattered to the floor
+behind his chair. With the weary slowness of despondence, he dragged
+himself to his feet and went behind his chair to pick up the
+cigarette-case. But, before he bent over it, and while he was looking
+fully and directly at it, his desk suddenly vanished. One moment it
+was there, a huge ornament of mahogany and glass; the next moment
+there was nothing.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>ony suddenly went rigid and stared at the empty space where his desk
+had stood. He put his hand to his forehead, wondering if his financial
+troubles were affecting his reason. By that time, another desk stood
+in the place.</p>
+
+<p>Tony ran over this strange circumstance mentally. His mental processes
+were active beneath, though dazed on the surface. His desk had stood
+there. While looking fully at it, all his senses intact, he had seen
+it vanish, and for a moment there had been nothing in its place. While
+he stared directly at the empty space from which the desk had
+disappeared, another desk had materialized there, like a flash.
+Perhaps, there had been a sort of jar, a tremor, of the floor and of
+the air, of everything. But the point was that his own desk, at which
+he had been working one moment, had suddenly vanished, and at the next
+moment another desk had appeared in its place.</p>
+
+<p>And what a desk! The one that now stood there was smaller than his own
+palatial one, and shabbier. A raw, unpleasant golden-oak, much
+scratched and scuffed. Its top was heaped and piled full of books and
+papers. In the middle of it stood a photograph of a girl, framed in
+red leather. Irresistibly, the sunny beauty of the face, the bright
+eyes, the firm little chin, the tall forehead topped by a shining mass
+of light curly hair, drew Tony's first glance. For a few moments his
+eyes rested delightedly on the picture.</p>
+
+<p>In a moment, however, Tony noticed that the books and papers on the
+desk were of a scientific character; and such is the nature of
+professional interest, that for the time he forgot his astonishment at
+how the desk had got there, in his absorption in the things heaped on
+top of it.</p>
+
+<p>Perhaps it isn't fair to give the impression that the desk was in
+disorder. It was merely busy; just as though someone who had been
+deeply engaged in working had for the moment stepped away. There was a
+row of books across the back edge, and Tony leaned over eagerly to
+glance at the titles.</p>
+
+<p>"'Theory of Parallels,' Lobatchevsky; 'Transformation of Complex
+Functions,' Riemann; 'Tensors and Geodesics,' Gauss," Tony read.
+"Hm&mdash;old stuff. But here's modern dope along the same line. 'Tensors,'
+by Christoffel; 'Absolute Differential Calculus,' by Ricci and Levi
+Civita. And Schr&ouml;dinger and Eddington and D'Abro. Looks like
+somebody's interested in Relativity. Hm!"</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">H</span>e bent over, his constantly increasing interest showing in the
+attitude of his body; he turned over papers and opened notebooks
+crowded full of handwritten figures. Last of all he noted the batch of
+manuscript directly in front of him in the middle of the front edge of
+the desk. It was typewritten, with corrections and interlineations all
+over it in purple ink.</p>
+
+<p>A title, "The Parallel Transformations of Equations for Matter,
+Energy, and Tensors," had been crossed out with purple ink, and "The
+Intimate Relation between Matter and Tensors" substituted. Tony bent
+over it and read. He was so fascinated that it did not even occur to
+him to speculate on the happy circumstance that the mysteriously
+appearing desk had brought its own scientific explanation with it. The
+title of the paper told him that its sheets would elucidate the
+apparently supernatural phenomenon, and all he did was to plunge
+breathlessly ahead in his eager reading. The article was short, about
+seven typewritten sheets. He took out his pencil and followed through
+the mathematical equations readily. Tony's mind was a brilliant, even
+though an erring one.</p>
+
+<p>Under the first article lay a second one. One glance at the title
+caused Tony to stiffen. Then he picked up the typewritten script and
+carried it across the big room of his laboratory, as far away from the
+desk as he could get. He put the girl's photograph in his pocket. Then
+he took heaps and armfuls of papers, books and notes and carried them
+from the desk to a bench in the far corner. For, as soon as he had
+read the title, "A Preliminary Report of Experimental Work in the
+Physical Manipulation of Tensors," a sudden icy panic gripped his
+heart lest the desk and its papers suddenly disappear before he had
+finished reading to the end of the fascinating explanation.</p>
+
+<p>We might add that it did not. For many weeks the desk remained
+standing in Tony's shop and laboratory, and he had the opportunity to
+study its contents thoroughly. But it took him only a few hours to
+grasp its secret, to add his own brilliant conception to it, and to
+form his great resolve. Once more Tony faced the world hopefully and
+enthusiastically.</p>
+
+
+<h2>PART II</h2>
+
+<h2><i>Vanishing Valuables</i></h2>
+
+<p><span class="f2">T</span>he police understood Tony's share in the exploits of Scarneck Ed
+thoroughly, and, chagrined at their failure to produce proof that
+would hold in court, they maintained a close and constant watch on
+that gifted gentleman long after crime matters in the city seemed to
+have been cleaned up and forgotten. For one thing, they still had
+hopes that something would turn up to enable them to round off their
+work and lock him up with his former pals; for another, they did not
+fully trust his future behavior. Nevertheless, for three or four
+months it seemed as though Tony had genuinely reformed. He lived in
+and for his laboratory and shop. All day the scouts could see him
+laboring therein, and far into the night he bent over benches and
+machines under shaded lights. Then, some other astonishing occurrences
+distracted their attention from Tony to other fields.</p>
+
+<p>One morning Mr. Ambrose Parakeet, private jewel broker, walked briskly
+out of the elevator on the fourteenth floor of the North American
+Building and unlocked the door of his office. He flung it open and
+started in, but stopped as if shot, uttered a queer, hoarse gurgle,
+and staggered against the door-casing. In a moment he recovered and
+began to shout:</p>
+
+<p>"Help! Help! Robbers!"</p>
+
+<p>Before long, several people had gathered. He stood there, gasping,
+pointing with his hand into the room. The eagerly peering onlookers
+could see that beside his desk stood an empty crate. It was somewhat
+old and weatherbeaten and looked as though it might have come from a
+buffet or a bookcase. He stood there and pointed at it and gasped, and
+the gathering crowd in the corridor wondered what sort of strange
+mental malady he had been seized with. The elevator girl, with trained
+promptness had at once summoned the manager of the building, who
+elbowed his way through the crowd and stood beside Mr. Parakeet.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">"T</span>here! There! Look! Where is it?" Mr. Parakeet was gasping slowly and
+gazing round in a circle. He was a little gray man of about sixty, and
+seemed utterly dazed and overcome.</p>
+
+<p>"What's wrong, Mr. Parakeet?" asked the building manager. "I didn't
+know you had your safe moved out."</p>
+
+<p>"But, no!" panted the bewildered old man. "I didn't. It's gone. Just
+gone. Last night at five o'clock I locked the office, and it was
+there, and everything was straight. What did you do? Who took it?"</p>
+
+<p>The building manager conducted the poor old man into the office, shut
+the door, and asked the crowd to disperse. He sat Mr. Parakeet down
+into the most comfortable chair he could find, and then barked
+snappily into the telephone a few times. Then he sat and stared about
+him, stopping occasionally to reassure the old man and ask him to be
+patient until things could be investigated.</p>
+
+<p>The building manager was an efficient man and knew his building and
+his tenants. He knew, as thoroughly as he knew his own office, that
+Mr. Parakeet had a medium-sized A. V. &amp; L. Co.'s safe weighing about
+three tons, that could not be carried up the elevator when Mr.
+Parakeet had moved in, and had been hoisted into the window with block
+and tackle. He knew that it was physically impossible for the safe to
+go down any of the elevators, and knew that none of the operators
+would dare move any kind of a safe without his permission.
+Nevertheless, with the aid of a police-sergeant, his night-shift, and
+the night-watchmen of his building and adjacent ones, it was
+definitely established that nothing had been moved in or out of the
+North American Building during the preceding twenty-four hours, either
+by elevator or through a window to the sidewalk.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>he newspapers took up the mystery with a shout. The prostrating loss
+suffered by Mr. Parakeet, amounting to over a hundred thousand
+dollars, added no little sensation to the story. A huge safe,
+disappearing into thin air, without a trace, and in its place an old
+wooden crate! What a mouthful for the scareheads! For several days
+newspapers kept up items about it, dwindling in size and strategic
+importance of position; for nothing further was ever found. Every bit
+of investigation, including that by scientific men from the University
+of Chicago, was futile; not a trace, not a suggestion did it yield.</p>
+
+<p>Six days later the tall scareheads leaped out again: "Another Safe
+Disappears! Absolutely No Trace! Some time during the night, the
+six-foot steel safe of the Simonson Loan Company vanished into thin
+air. In the morning a dilapidated iron oil-cask was found in its
+place. The safe was so large and heavy that it could not have been
+moved without a large truck, special hoisting apparatus, a crew of
+men, and some hours of time. The store was brightly lighted during the
+entire night, and two watchmen patrolled it regularly. They report
+that they saw and heard nothing unusual, and were very much amazed
+when shown the oil-cask standing where the safe had been the night
+before." The accounts in the various papers were substantially the
+same.</p>
+
+<p>Newspaper readers throughout the city and its environs were very much
+intrigued. Such a thing was very exciting and mystifying; but it was
+so far out of touch with their own lives that it did not affect them
+very much at any time except when they were reading the paper or
+discussing it in conversation. The police were the ones who were doing
+the real worrying. And, when the following week two more safes
+disappeared, insurance companies began to take an interest in the
+matter; and everyone who had any considerable amount of valuables in
+store began to feel panicky.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>he circumstances surrounding the disappearance of the last of the
+series, the fourth, were especially amazing. This was also a jewelry
+safe. Canzoni's is a popular firm that rents a quarter of a floor in a
+big department store, and does a large volume of moderate-priced
+business. The receipts are stored in a heavy portable safe in a corner
+of the silverware section until evening, when they are carried to the
+large vault of the big store. One Saturday afternoon after a
+particularly busy day, Mr. Shipley, Canzoni's manager, was watching
+the hands of the clock creep toward five-thirty. He leaned on a
+counter and watched the clerks putting away goods for the night; he
+glanced idly toward the safe which he intended to open in a few
+minutes. The doormen had already taken their stations to keep out
+further customers. Then he glanced back at the safe, and it wasn't
+there!</p>
+
+<p>Mr. Shipley drew a deep breath. The safe disappearances he had read
+about flashed through his mind. But he didn't believe it. It couldn't
+be! Yet, there was the empty corner with the birch panels forming the
+back of the show-windows, and no safe. In a daze, he walked over to
+the corner, intending to feel about with his hands and make sure the
+safe was really gone. Before he got there, there flashed into sight in
+place of the safe, a barrel of dark wood; and in a moment there was a
+strong odor of vinegar.</p>
+
+<p>Things spun around with Mr. Shipley for a few moments. He grasped a
+counter and looked wildly about him. Clerks were hurrying with the
+covering of counters; no one seemed to have noticed anything. He stood
+a moment, gritted his teeth, and breathed deeply, and soon was master
+of himself. He stood and waited until the last customer was gone, and
+then called several clerks and pointed to where the safe had stood.</p>
+
+<p>Within the space of a month, thirteen safes and three million dollars
+worth of money or property had disappeared. The police were dazed and
+desperate, and business was in a panic. Scientific men were appealed
+to, to help solve the riddle, but were helpless. Many of them agreed
+that though in theory such things were explainable, science was as yet
+far from any known means of bringing them about in actuality.
+Insurance companies spent fabulous sums on investigation, and, failing
+to get results, raised their premiums to impossible levels.</p>

+<h2>PART III</h2>
+
+<h2><i>The Lady of the Picture</i></h2>
+
+<p><span class="f2">P</span>hil Hurren, often known as "Zip" Hurren, reporter on the <i>Examiner</i>,
+felt, on the day the managing editor called him into the sanctum, that
+fortune could smile on him no more brightly. There wasn't anything
+brighter.</p>
+
+<p>"You stand well with the detective bureau," his boss had said; "and
+you've followed this safe-disappearing stuff pretty closely. You're
+relieved of everything else for the time being. Get on that business,
+and see that the public hears from the <i>Examiner</i>!"</p>
+
+<p>Phil knew better than to say any more, for before he recovered from
+his surprise, the editor had turned his back, buried himself in his
+work on the desk, and forgotten that Phil was there. Nor did Phil
+waste any real time in rejoicing. That is why he was called "Zip."
+When things happened, whether it was luck or system, Phil was usually
+there. In sixty seconds more, Phil was in a taxicab, whirling toward
+police headquarters.</p>
+
+<p>Luck or system, he didn't know, but he struck it again. The big wagon
+was just starting away from the station door when he arrived, crowded
+inside with bluecoats and plainclothes-men. The burly, red-faced man
+with chevrons on his sleeve, sitting beside the driver, saw Phil jump
+out, and motioned with his hand. Phil leaped up on the back step of
+the vehicle and hung on for dear life with his fingers through the
+wire grating as they careened through the streets. The men on the
+inside grinned at him; a number of them knew him and liked him.
+Gradually the door was opened and he crowded in. He found Sergeant
+Johnson and eyed him mutely.</p>
+
+<p>"How the hell do you find these things out, I'd like to know," the
+sergeant exclaimed. "Are you a mind-reader?"</p>
+
+<p>"I don't really know anything," Phil admitted with that humility which
+the police like on the part of newspaper men and seldom meet with. "Do
+you mind?"</p>
+
+<p>"No objection," grunted the sergeant. "Been watching all the old
+crooks since these safes have been popping. Nothin' much on any of
+them, except this slippery wop, Tony Costello. No, we haven't caught
+him at anything. Seems to be keeping close and minding his own
+business. Working in his laboratory. Ought to make a good living if he
+turned honest; clever guy, he seems. But he's been too prosperous
+lately. Lots of machinery delivered to his place; we traced it to the
+manufacturers and find it cost thousands. Big deposits in his banks.
+But, no trace of his having sold anything or worked at anything
+outside his own place. So, we're running over to surprise him and help
+him get the cobwebs out of his closets."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>he raid on Tony Costello's shop and laboratory disclosed nothing
+whatever. They surrounded the place effectively and surprised Tony
+genuinely. But a thorough search of every nook and cranny revealed
+nothing whatever of a suspicious nature. There was merely a tremendous
+amount of apparatus and machinery that none of the raiding party
+understood anything about. Tony's person was also thoroughly searched,
+and the leather-framed photograph of the beautiful unknown girl was
+found.</p>
+
+<p>"Who's this?" the sergeant demanded. "She don't look like anyone that
+might belong to your crowd."</p>
+
+<p>"I don't know," Tony replied.</p>
+
+<p>"Whad'ya mean, don't know?" The sergeant gave him a rough shake.
+"What'ya carryin' it for, then?"</p>
+
+<p>"I had really forgotten that it was in my pocket," Tony replied
+calmly, at his ease. "I found it in a hotel room one day, and liked
+the looks of it."</p>
+
+<p>"I know you're lying there," the sergeant said, "though I'm ready to
+believe that you don't know her. Too high up for you. Well, it looks
+suspicious and we'll take the picture."</p>
+
+<p>"Boy!" gasped Phil. "What a girl she must be in person! Even the
+picture would stand out among a thousand. May I have the picture,
+Sergeant?"</p>
+
+<p>"You can come and get a copy of it to-morrow. We'll have it copied and
+see if we can trace the subject of it. That might tell us something."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>he following morning Phil was at Police Headquarters to pick up
+further information, and to get a copy of the girl's photograph. Like
+the police, he could not keep his mind off the idea that there was
+some association between the crooked engineer and the disappearance of
+the safes. It seemed to fit too well. The scientific nature of the
+phenomena, Tony Costello's well known reputation for scientific
+brilliance, and his recent affluence; what else could it mean? In some
+way, Tony was getting at these safes. But how? And how prove it? Most
+exhaustive searches failed to reveal any traces of the safes anywhere.
+If any fragment of one of them had appeared in New York or San
+Francisco, the news would have come at once, such was the sensation
+all over the country that the series of disappearances had caused.
+Tony's calm insolence during the raid, his attitude of waiting
+patiently till the police should have had their fun and have it over
+with so that he might be left at peace again, showed that he must be
+guilty, for anyone else would have protested and felt deeply injured
+and insulted. He seemed to be enjoying their discomfiture, and
+absolutely confident of his own safety.</p>
+
+<p>"There's got to be some way of getting him," Phil mused; and he mused
+almost absent-mindedly, for he was gazing at the photograph of the
+girl. For many minutes he looked at it, and then put it silently into
+his pocket.</p>
+
+<p>Five o'clock in the evening of that same day came the news of another
+safe disappearance. Phil got his tip over the phone, and in fifteen
+minutes was at the scene. It was too much like the others to go into
+detail about; a six-foot portable safe had suddenly disappeared right
+in front of the eyes of the office staff of The Epicure, a huge
+restaurant and cafeteria that fed five thousand people three times a
+day. In its place stood a ragged, rusty old Ford coupe body. He went
+away from there, shaking his head.</p>
+
+<p>Then suddenly in the midst of his dinner, he jumped up, and ran. An
+idea had leaped into his head.</p>
+
+<p>"Right after one of these things pops is the time to take a peek at
+Tony," he said to himself, and immediately he was on the way.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">B</span>ut how to get his peep was not so easy a problem. When he alighted
+from his cab a block away from Tony's building, he was hesitant about
+approaching it. Tony knew him, and might see him first. Phil circled
+the brick building, keeping under cover or far enough away; all around
+it was a belt of thirty feet of lawn between the building and the
+sidewalk. Ought he have called the police and given them his idea? Or
+should he wait till darkness and see what he could do alone?</p>
+
+<p>Then suddenly he saw her. Across the street, standing in the shelter
+of a delivery truck in front of an apartment, she was observing Tony's
+building intently. The aristocratic chin, the brightness of the eyes,
+the waves of her hair, and the general sunny expression! It could not
+be anyone else. Post haste he ran across the street.</p>
+
+<p>"Pardon me!" he cried excitedly, lifting his hat and then digging
+hastily into his inner pocket. "I'm sure you must be the&mdash;"</p>
+
+<p>"Well, the nerve!" the young woman said icily, and pointing her chin
+at the opposite horizon she walked haughtily away.</p>
+
+<p>By that time Phil had dug out his picture and was running after her.</p>
+
+<p>"Please," he said, "just a moment!" And he held the picture out in
+front of her face.</p>
+
+<p>"Now, where in the world&mdash;?" She looked at him in puzzled and
+indignant inquiry, and then burst out laughing.</p>
+
+<p>"It <i>is</i> you, isn't it?" Phil asked. "What are you laughing at?"</p>
+
+<p>"Oh, you looked so abject. I'm sure your intentions must be good. Now
+tell me where you got my picture."</p>
+
+<p>"Let us walk this way," suggested Phil, leading away from Tony's
+building.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">A</span>nd, as they walked, he told her the story. When he got through she
+stood and looked at him a long time in silence.</p>
+
+<p>"You look square to me," she said. "You're working on my side already.
+Will you help me."</p>
+
+<p>"I'll do anything&mdash;anything&mdash;" Phil said, and couldn't think of any
+other way of expressing his willingness, for the wonderful eyes bore
+radiantly upon him.</p>
+
+<p>"First I must tell you my story," she began. "But before I can do so,
+you must promise me that it is to remain an absolute secret. You're a
+newspaper man&mdash;"</p>
+
+<p>Phil gave his promise readily.</p>
+
+<p>"My father is Professor Bloomsbury at the University of Chicago. He
+has been experimenting in mathematical physics, and I have been
+assisting him. He has succeeded in proving experimentally the concept
+of tensors. A tensor is a mathematical expression for the fact that
+space is smooth and flat, in three dimensions, only at an infinite
+distance from matter; in the neighborhood of a particle of matter,
+there is a pucker or a wrinkle in space. My father has found that by
+suddenly removing a portion of matter from out of space, the pucker
+flattens out. If the matter is heavy enough and its removal sudden
+enough, there is a violent disturbance of space. By planning all the
+steps carefully my father has succeeded in swinging a section of
+space on a pivot through an angle of 180 degrees, and causing two
+portions of space to change places through hyperspace, or as you might
+express it popularly, through the fourth dimension."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">P</span>hil held his hands to his head.</p>
+
+<p>"It is not difficult," she went on smiling. "Loan me your pocket knife
+and a piece of paper from your notebook. If I cut out a rectangular
+piece of paper from this sheet and mount it on a pivot or shaft at A
+B, I can rotate it through 180 degrees, just like a child's
+teeter-totter, so that X will be where Y originally was. That is in
+two dimensions. Now, simply add one dimension all the way round and
+you will have what daddy is doing with space. He does it by shoving
+fifty or a hundred pounds of lead right out of space; the sudden
+flattening out of the tensors causes a section of space to flop
+around, and two portions of space change places. The first time he
+tried it, his desk disappeared, and we've never seen it again. We've
+thought it was somewhere out in hyperspace; but this terrible story of
+yours about disappearing safes, and the fact that you have this
+picture, means that someone has got the desk."</p>
+
+<p>"Surely you must have suspected that long ago, when the disappearances
+first began?" Phil suggested.</p>
+
+<p>"I've just returned from Europe," said Miss Bloomsbury. "I was
+tremendously puzzled when I got my first newspapers in New York and
+read about the safes. Gradually I gathered all the news on the
+subject, and it seemed most reasonable to suspect this gangster
+engineer."</p>
+
+<p>"Great minds and same channels," Phil smiled. "But your father. Why
+didn't he speak up when the safes began to pop?"</p>
+
+<p>"Ha! ha!" she laughed a tinkly little laugh. "My father doesn't know
+what safes are for, nor who is President, nor that there has been a
+war. Mother and I take care of him, and he works on tensors. He has
+probably never heard about the safes."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">"W</span>hat were you going to do around here?" Phil asked, marveling at the
+courage of the girl who had come to look the situation over
+personally.</p>
+
+<p>"I hadn't formed any definite plans. I just wanted to look about
+first."</p>
+
+<p>"Well," said Phil, "as you will soon see by the papers, another safe
+has puffed out. It occurred to me that we might find out something by
+spying about here immediately after one of the disappearances. That's
+why I'm here. If you'll tell me where you live, or wait for me at some
+safe place, I'll come and report to you as soon as I find out
+anything."</p>
+
+<p>"Oho! So that's the kind of a girl you think I am!" She laughed
+sunnily again. "No, Mr. Reporter. Either we reconnoiter together, or
+each on our own."</p>
+
+<p>"Oh, together, by all means," said Phil so earnestly that she laughed
+again. "And since we'd better wait for darkness, let's have something
+to eat somewhere. I didn't finish my dinner."</p>
+
+<p>Phil found Ione Bloomsbury in person to be even more wonderful than
+her photograph suggested. Obviously she had brains; it was apparent,
+too that she had breeding. Her cheerful view of the world was like a
+tonic for tired nerves; and withal, she had a gentle sort of courtesy
+in her manner that may have been old-fashioned, but it was almost too
+much for Phil. Before the dinner was over, he would have laid his
+heart at her feet. It gave him a thrill that went to his head, to have
+her by his side, slipping along through the darkness toward Tony's
+building.</p>
+
+<p>This building was a one-story brick affair with a vast amount of
+window space. From the sidewalk they could see faint lights glowing
+within, but could make out no further details. They therefore selected
+the darkest side of the building, and made their way hurriedly across
+the lawn. Here, they found, they could see the crowding apparatus
+within the one long room fairly well. They looked into one window
+after another, making a circuit around the building, until Phil
+suddenly clutched the girl's arm.</p>
+
+<p>"Look!" he whispered. "Straight ahead and a little to the left!"</p>
+
+<p>At the place he indicated stood a tall safe. Across the top of its
+door were painted in gold letters, the words: "The Epicure."</p>
+
+<p>"That's the safe that went to-night," whispered Phil. "That's all we
+need to know. Now, quick to a telephone!"</p>
+
+<p>"Oh," said a gentle, ironic voice behind them, "not so quick!"</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>hey whirled around and found themselves looking into two automatic
+pistols, and behind them in the light of the street lamps, the
+sardonic smile of Tony Costello.</p>
+
+<p>"Charmed at your kind interest in my playthings, I'm sure," he purred.
+"Only it leaves me in an embarrassing position. I'm not exactly sure
+what to do about it. Kindly step inside while I think."</p>
+
+<p>Phil made a move sidewise along the wall.</p>
+
+<p>"Stop!" barked Costello sharply. "Of course," his voice was quiet
+again, "that might be the simplest way out. I think I am within my
+legal rights if I shoot people who are trying to break into my
+property. Yet, that would be messy&mdash;not neat. Better step in. The
+window swings outward."</p>
+
+<p>At the point of his pistols they clambered through the window, and he
+came in after them. He kept on talking, as though to himself, but loud
+enough for them to hear.</p>
+
+<p>"Yes, we want some way out that is neater than that. Hm! Violence
+distresses me. Never liked Ed's rough methods. Yet, this is
+embarrassing."</p>
+
+<p>He turned to them.</p>
+
+<p>"What did you really want here? I see that you are the <i>Examiner's</i>
+reporter, and that you are the lady of the photograph. What did you
+come here for? Ah, yes, the safe. Well, go over and look at it."</p>
+
+<p>As they hesitated, he stamped his foot and shrilled crankily:</p>
+
+<p>"I mean it! Go, look at the safe! Is there anything else you want to
+know?"</p>
+
+<p>"Yes," said Phil coolly, his self-control returning, "where are the
+other safes?"</p>
+
+<p>"Oh. Anything to oblige. Last requests are a sort of point of honor,
+aren't they. Ought to grant them. Stand close to that safe!"</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">H</span>e backed away, his guns levelled at them. He laid down the right one,
+keeping the left one aimed, and moved some knobs on a dial and threw
+over a big switch. A muffled rumbling and whirring began somewhere;
+and then, slowly, a block of tables and apparatus ten feet square rose
+upward toward the ceiling. A section of the floor on which they stood
+came up, supported by columns, and now formed the roof of a room that
+had risen out of the floor. In it were four safes.</p>
+
+<p>"Poor old Ed!" sighed Tony. "There was a time when he had a lot of
+good stuff put away down there. I've got six rooms like that. Well,
+the good old times are over."</p>
+
+<p>He threw out the switch and the whole mass sank slowly and silently
+downward till the floor was level and there was no further sign of it.
+Then he backed away to another table, across the room from them,
+keeping his gun levelled.</p>
+
+<p>"Too bad," he said. "I don't like to do these things. But&mdash;" he sighed
+deeply, "self-preservation. Now I'm going to flip you out, yes,
+<i>out</i>, into a strange region. I've never been there. I don't know if
+there is food or drink there. I hope so, for you'll never get back
+here."</p>
+
+<p>Phil stiffened. He determined to leap and risk a shot. But he was too
+late. Tony's hand came down on a switch. There was a sudden,
+nauseating jar. The laboratory vanished.</p>
+
+<p>There was only the safe, Ione Bloomsbury and himself, and a small
+circle of concrete floor extending to a dim little horizon a dozen
+feet away. Beyond that, nothing. Not blue, as the sky is. Not black,
+as dark, empty spaces are. It suggested black, because there was no
+impression of light or color on the eyes; but it wasn't black. It was
+nothingness.</p>
+
+
+<h2>PART IV</h2>
+
+<h2><i>Marooned in Hyperspace</i></h2>
+
+<p><span class="f2">"I</span>&nbsp;suppose you realize what he has done?" Miss Bloomsbury inquired.</p>
+
+<p>"Couldn't be too sure, but it looks like plenty. What's the equation
+for it?" Beneath his jocularity, Phil felt a tremendous sinking within
+him. It looked serious, despite the fact that he did not understand it
+at all.</p>
+
+<p>"He has swung us out into hyperspace, or into the fourth dimension, as
+your newspaper readers might understand it, and has let us hang there.
+Remember our slip of paper. Suppose X and Y were swung out of the
+plane of the paper and allowed to remain at an angle with it. We are
+at an angle with space, out in hyperspace."</p>
+
+<p>There was a period of bewilderment, almost panic, in which they both
+felt so physically weak that they had to sit down on the concrete and
+stare at each other mutely. But this passed and their natural courage
+soon reasserted itself. Their first thought was to take stock of what
+information they could get on their situation; and their first step
+was to venture as close as possible to the queer little horizon which
+lay almost at their very feet. It gave them a frightened feeling, as
+though they were standing high up on a precipice or tower.</p>
+
+<p>To their surprise, the horizon receded as they walked toward it,
+always remaining about a dozen feet away from them. At first they
+walked on concrete and then came to a crumbly edge of it and found
+themselves stepping on hard, sandy earth. Later there was rock,
+sometimes granite-like, sometimes black and shiny. But what they saw
+underfoot was nothing, compared with the glimpses of things they got
+out in the surrounding emptiness. First there was a vast space in
+which a soft light shone, and in which there were countless spheres of
+various sizes, motionlessly suspended. The spheres seemed to be made
+of wood, a green, sap-filled, unseasoned wood. The scene was visible
+for a few seconds, and vanished suddenly as they walked on. This
+astonished them; so they stepped back a pace or two and saw it again;
+and as they moved on, it disappeared again.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>hen there was a great stretch of water in which the backs of huge
+monsters rolled and from which a hot wind blew for a few instants
+until they passed on and the scene vanished. There was a short walk
+with nothing but emptiness, and then there appeared huge, oblique,
+cubistic looking rows of jagged rocks in wild, dizzy formations that
+didn't look possible; and farther on, after another interval of
+emptiness, a tangle of brown, ropey vines with black-green leaves on
+them, an immense space filled with serpentine swinging loops and
+lengths of innumerable vines. Several loops projected so near them
+that they could have reached out and touched them had they wished.</p>
+
+<p>"This is too much for me!" Phil gasped. "Have we gone crazy? Or did
+he kill us, and is this Purgatory?"</p>
+
+<p>Ione smiled and shook her little head in which she had a goodly store
+of modern mathematics stored away.</p>
+
+<p>"These must be glimpses of other 'spaces' besides our own space. If we
+could see in four dimensions we could see them all spread out before
+us. But we can only perceive in three dimensions; therefore, as we
+walk through hyperspace, past the different 'spaces' which are ranged
+about in it, we get a glimpse into such of them as are parallel with
+our own space. Can you understand that?"</p>
+
+<p>"Oh, yes," groaned Phil. "It sounds just about like it looks. But,
+don't mind me. Go on, have your fun."</p>
+
+<p>"I've been thinking about those wooden spheres," continued Ione. "I'm
+sure they must be sections of trees that are cut crosswise by our
+'space;' they grow in three dimensions, but only two of them are our
+dimensions and a third is strange to us. We see only three-dimensional
+sections of them, which are spheres. There is more of them, that we
+cannot see, in another dimension."</p>
+
+<p>"Yes, yes. Just as plain as the Jabberwock!"</p>
+
+<p>"Look! There's a real Jabberwock!" exclaimed Ione.</p>
+
+<p>On ahead of them they saw a number of creatures that seemed to be made
+of painted wooden balls in different colors, joined together.</p>
+
+<p>"Tinkertoys!" exclaimed Phil. "Live ones! Big ones!"</p>
+
+<p>The animals, though they looked for all the world as though they were
+made of painted wood, moved with jerky motions and clattered and
+snarled.</p>
+
+<p>"There is probably more to <i>them</i> in another dimension," Ione said.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">S</span>uddenly one of the beasts approached them with a leap. There were two
+big eyes and two rows of teeth that came together with a snap, right
+on Phil's trouser-leg. He jerked himself away, sacrificing some square
+inches of trouser-leg, and, whirling around, kicked at the thing with
+all his force. It almost paralyzed his foot, for the animal seemed to
+be made of wood or bone. But it disappeared, and, as it did, both of
+them felt a queer, nauseating jolt. A few more minutes' walk brought
+them back to the safe without seeing any more spaces; and the sight of
+its black iron bulk filled them with a home-like relief, which in a
+moment they recognized as a mockery.</p>
+
+<p>"Are we on a sphere of some sort?" Phil asked.</p>
+
+<p>"Probably on an irregular mass of matter," Ione replied, "part of
+which is Tony's concrete floor, and part of which comes out of some
+other dimension. This mass of matter is at one end of a long, bar-like
+portion of space, the middle of which is pivoted in our world,
+somewhere in Chicago, and both ends of which are free in hyperspace."</p>
+
+<p>"Then," suggested Phil, "why can't we walk down to the axle on which
+it is balanced, and step out into Chicago?"</p>
+
+<p>"Because there isn't any <i>matter</i> for us to walk on. We are not able
+to move about in space, in three dimensions, you know. We can only get
+around in two dimensions, on the surface of <i>matter</i>."</p>
+
+<p>"Well, let's try another exploration trip at right angles to our first
+one. After all, these 'spaces' are an interesting show, and I want to
+see some more."</p>
+
+<p>They started out in the selected direction, and after a short walk got
+a glimpse of a vast space dotted with stars and nebulae, with two
+bright moons sailing overhead. A few steps farther on was a wall of
+solid granite, near enough to touch with their hands. Again, there was
+an intensely active mass of weaving bright stripes and loops and
+circles, seeming to consist of light only, and making them dizzy in a
+few seconds. Ione wondered if it might not be something like an
+organic molecule on a large scale. Again, odd, queer, indescribable
+shapes and outlines would appear and disappear, obviously
+three-dimensional sections of multi-dimensional things, cut by space.
+Once they passed a place of intense cold and terrific noise and
+escaped destruction or lunacy only because it took them the merest
+instant to get past.</p>
+
+<p>They arrived back at the safe, very much fatigued from the strain,
+their minds woefully confused. Hunger and thirst were beginning to
+thrust up their little reminders; and for the first time the terrors
+of their position, flung out into hyperspace on a small, barren piece
+of matter, began to seem real.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">A</span>fter a rest they started out again. As Phil had touched, in kicking
+it, a creature from another "space," perhaps they might find water and
+even food somewhere. They retraced their first steps to the spot where
+they had at first seen water. They found it again and were able to dip
+their hands into it. It was warm, and too salty to drink. They came to
+the place with the creepers or vines, and Phil reached out and seized
+one of them. It was heavy, rubbery, and elastic, stretching readily as
+he pulled it.</p>
+
+<p>"These little lurches that we feel must be the snapping back of the
+space-puckers as expressed by tensors," Ione remarked. "Every time
+matter goes in or out of space, the nature of space is altered."</p>
+
+<p>"Well," observed Phil, releasing the vine, "I'd better be careful. If
+one of these things hauls me off here, our last bond with home is
+gone. I don't want to get lost in some other space."</p>
+
+<p>As he released the vines they snapped back to their places, and the
+forest of them dimmed a little and reappeared.</p>
+
+<p>They made the round again, dodging cautiously past the point where
+they had previously found the "Tinkertoy" animals, and succeeded in
+getting past their snapping teeth. But no promise of food or water did
+they find anywhere.</p>
+
+<p>"Looks like we're sunk," observed Phil, as they dropped down on the
+concrete to rest, leaning their backs against the safe.</p>
+
+<p>How time counted in hyperspace, neither Phil nor Ione could tell; Phil
+knew that his watch was running. He knew that it was ages and ages
+that he sat with his back against the safe, reviewing all the events
+of his put life, and thinking of this ignominious end to a lively
+career! He swore half aloud; then suddenly looked at Ione, ready to
+apologize. He found her weeping silently.</p>
+
+<p>"I should never have let you come into the building with me," he
+stammered in confusion at her tears.</p>
+
+<p>"Oh, what do I care what becomes of <i>me</i>!" she exclaimed angrily. "But
+who will take care of poor daddy? He doesn't even know when it's time
+to eat." And she burst into a fresh fit of weeping.</p>
+
+<p>Phil bent his head in the dumbness of profound despair.</p>
+
+
+<h2>PART V</h2>
+
+<h2><i>The Reversible Equation</i></h2>
+
+<p><span class="f2">D</span>espair, however, is a luxury. Necessity is a stimulus. With the
+parchings of thirst and the gnawings of hunger, the two young people
+ceased swearing and weeping. Phil got up and paced about and sat down
+again. Ione's tears stopped and dried, and she sat and thought.</p>
+
+<p>In the back of her mind there had been forming a vague sort of an
+idea, which had signalled ahead of itself that there was hope. She sat
+there and desperately drove her reason to its utmost efforts, to find
+that idea and bring it to the surface of consciousness. Hand to hand
+fights with wild animals, battles between ships of the line, vicious
+duels between ace-aviators in the clouds are tense fights; but they
+cannot compare in anxious difficulty with the struggle to bring up an
+unformed idea out of the subconscious mind&mdash;especially when one knows
+that the idea is there, and that it must be found to save one's life.</p>
+
+<p>"Ione!" exclaimed Phil. It was the first time he had used the name.
+"What is the matter? You are as tense as a&mdash;"</p>
+
+<p>"Ah!" cried Ione, springing up. "Tense! Tensors! I have it!"</p>
+
+<p>Phil gazed at her in alarm. She laughed; at first it was a strained
+laugh, but gradually it melted into her sunny one.</p>
+
+<p>"No, I'm not crazy. I knew there was a way out, and I've been trying
+to reason it out. How simple. You remember the little jolts when you
+pulled at the vines and when you kicked the funny animal? Tensors.
+Matter and space are so closely interrelated that you can't move
+matter in or out of space without causing disturbance, recoils, and
+tremors in space. Those bits of matter were small, and produced only a
+slight disturbance. It takes about a hundred pounds of lead to swing
+this segment&mdash;"</p>
+
+<p>"Oho! Got you!" exclaimed Phil. "Not so dumb! The safe!"</p>
+
+<p>"Yes. The safe!" Ione cried.</p>
+
+<p>"Throw it off and watch us swing, eh? What would happen?"</p>
+
+<p>"I might calculate it if I knew the weight of the safe."</p>
+
+<p>"No calculating when I'm around," Phil said. "It couldn't make things
+any worse. Try it first and calculate afterwards."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>hey got behind the safe and pushed, and their combined strength
+against it was about as effective as it would have been in moving the
+Peoples' Gas Building. They sat down again in despair.</p>
+
+<p>"Suppose we <i>could</i> budge it," Ione said. "All we could do would be to
+push it around, this piece of matter we are on. That wouldn't help.
+We've got to get it out of space. We can't push it hard enough to do
+that. It's got to be shot out suddenly&mdash;"</p>
+
+<p>"And we haven't got a gun handy," Phil remarked droopingly.</p>
+
+<p>"Not exactly a gun. A sort of sling&mdash;"</p>
+
+<p>Phil leaped to his feet.</p>
+
+<p>"A sling. Why! To be sure! The vines!"</p>
+
+<p>Without another word, both of them got up and ran. They hastened in a
+direction opposite to the one they had at first taken on their trip of
+exploration, and this brought them first past the "space" of the
+Tinkertoy-like animals. As they went by, several of these beasts
+darted at them, one of them snapping at Ione's heels. She uttered a
+scream, causing Phil to turn about and kick right and left among them.
+He drove them back and escaped from them, rejoining Ione.</p>
+
+<p>"Wait," he said, when they reached the vines. "Remember those wooden
+balls. If I could get a few to throw at those critters&mdash;"</p>
+
+<p>In a moment they were off, and finally arrived at the point from which
+they first saw the balls. Odd it seemed, how they hung suspended in
+space, thousands of them, all sizes. Phil reached out and grasped one
+about the size of a baseball and drew it toward himself. He felt a
+dizzy lurch and heard Ione scream.</p>
+
+<p>"Let go!" she screamed again.</p>
+
+<p>When he suddenly realized what was going on, he found himself
+prostrate on the ground, with Ione across him, her arms about his
+knees.</p>
+
+<p>"Do you realize," she panted, disentangling herself, "that you were
+pulling yourself out of this space into that one?"</p>
+
+<p>"Thanks!" said Phil. "Never say die. More careful this time, and a
+smaller one."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">H</span>e reached out and grasped a ball smaller than a golf-ball, and pulled
+carefully, keeping an eye upon Ione. There was resistance to his pull,
+but gradually the ball came. It seemed heavy. There was a crack as of
+breaking wood, and he fell backward, with a wave of nausea sweeping
+strongly over him. He gazed in amazement at a heavy wooden stick that
+he held in his hands. The only thing about it that suggested the ball
+for which he had reached was its diameter.</p>
+
+<p>"Can't understand it, but appreciate it just the same," he said. He
+broke the stick in two, and had two excellent clubs.</p>
+
+<p>"Simple," Ione replied. "The balls are cross-sections of these trees
+or sticks which grow in a 'space' at right angles to our own; and we
+only see their three-dimensional cross-sections."</p>
+
+<p>"Yes," said Phil. "Cabbages and kings. I'm for you and the party."</p>
+
+<p>A short walk brought them to the "space" of the vines. After testing
+the matter out carefully, they found that they could each pull two of
+them at a time. The vines stretched amazingly when they found those
+whose far ends were fixed firmly in the tangle, permitting them to
+carry their own ends along with them toward the safe. Phil wound his
+vines around his left arm and stuck one club through his belt. The
+other he got ready for the wooden animals.</p>
+
+<p>He needed it. The size of the pack was doubled, and he rapped them
+till his hand was numb before he and Ione got by. Their vines drew out
+thin, but held until they were firmly tied about the safe. They went
+back after four more.</p>
+
+<p>"I should judge," said Phil, "that by the time we get thirty or forty,
+the elastic pull will be strong enough to drag the safe back with
+them as they snap back home."</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>rip after trip they made, fighting the wooden animals with their
+clubs each time. Their clothes were torn, and their legs bleeding;
+their throats were dry and lips cracked. The hard animals seemed to
+have a persistent, mechanical ferocity that was undismayed by
+hammering with the clubs and by repeated repulses. Phil could not seem
+to hurt them; he merely knocked them away. Finally, on the ninth trip,
+Ione collapsed when she reached the safe. As she fell, the elasticity
+of the vines began slowly to drag her back with them. Phil was forced
+to sit across her knees while he tied his own vines about the safe.
+Then he released her and added her vines to the great cable about the
+safe.</p>
+
+<p>An overbold hard animal rattled up and snapped at her. Goaded to fury,
+Phil swung at it with his club and hurled it through the air. He could
+feel the lurch as it left his space and entered another. Then he
+pushed with his mightiest effort against the safe. It budged, and slid
+a few inches. He used his stick as a lever. It moved again, a little
+faster. Ione struggled to her feet and tried to help, but her efforts
+were ineffectual.</p>
+
+<p>With one arm about her, Phil pried again under the safe, knowing that
+another trip after vines was out of question. Another animal snapped
+at their heels. For a while, it was kick backwards, then a shove at
+the safe. Each time the safe moved. The sight of its movement revived
+Ione, so that she was able to push also. Gradually it acquired a
+steady motion, pulled by the contraction of the vines; its progress
+soon became faster and faster. Phil was about to follow it and give it
+another push, when Ione drew him back.</p>
+
+<p>Suddenly they experienced a sinking sensation and a fearful vertigo.
+The snapping animals faded. Ahead of them was the forest of vines, and
+they saw the safe hurled into it, crashing, plunging into the tangled
+mass. The whole view crumpled and moved upwards like a swirl of leaves
+in a wind, and then vanished with a snap.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">T</span>hey were sick and dizzy, but tremendously curious to see everything.
+The water, the cubistic cliffs, the vast space full of balls, all
+curiously blurred, appeared in succession. There were blank spaces and
+then blurred sights of things which they did not recognize, never
+having seen them before. Then the dizziness and the nausea abated, and
+ahead of them was a vast yellow blue, a huge nebula, and in it were
+double-colored suns and ringed planets with swarms of moons; this
+glorious sight remained for many seconds, as they gazed at it in
+panting astonishment, half reclining on the concrete; and then it
+faded. Again the nausea came on; again the succession of blurred
+views. Eventually the myriad spheres, the water with the leviathans,
+the forest of vines, each succeeding scene grew more blurred. Their
+nausea was correspondingly increased, till they were forced to lie
+down on the ground from illness.</p>
+
+<p>When their giddiness abated, there were blurring views again. There
+was an impression as though the speed of a train were decreasing as
+one looks out of the window. And how one view held for several
+seconds, a vast and wild mountain-range with glaciers and snow peaks
+by moonlight. When this faded gradually, the scenes began to flick by,
+more and more rapidly, and grew blurred. Phil and Ione were attacked
+by nausea until, again, they had to lie down. After that came the
+familiar succession: the wooden animals, the tangle of vines, the vast
+sea, the spheres, and more blurred scenes. Then came a pause, with
+the nebula and the glorious suns swinging into view once again.</p>
+
+<p>"Oh, I understand!" Ione exclaimed; "We're swinging. The safe was so
+heavy that we swung too violently, too far, and back again&mdash;"</p>
+
+<p>"And we keep going till it knocks us out, or till the old cat dies,"
+added Phil.</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">H</span>owever, they found that after a number of repetitions of the same
+program, their giddiness was becoming less; and instead of lying down
+in the middle of the swing, they could look about. Then it occurred to
+Phil to time the interval between the nebula and the mountain-range.
+When the exact halfway point was determined, and after several more
+swings, they could see dimly the windows and machinery of Tony's
+laboratory flash by when they passed the middle.</p>
+
+<p>"I don't mean to be a crepe-hanger, but how do you know we will stop
+at the right point?" Phil asked.</p>
+
+<p>"I don't," replied Ione cheerfully. "But mathematics says so. A freely
+oscillating segment of space would naturally come to equilibrium in a
+position parallel to the rest of its own space, would it not?"</p>
+
+<p>There came a swing when they did not reach the nebula on the one hand
+and the mountain-range on the other. After that, views dropped off
+from either end of the swing quite rapidly, and before many minutes,
+they looked into Tony's laboratory a large portion of the time. For
+many seconds the laboratory held; then it would gradually fade, and
+reappear again, only to fade into empty nothingness all around.</p>
+
+<p>"The old cat's dead," Phil finally announced.</p>
+
+<p>They sat and stared about them as the laboratory held steady and no
+further intervening periods of blankness intervened. They both sighed
+deeply and slumped over on the ground to rest.</p>
+
+<p>"Bang! bang! bang!"</p>
+
+<hr style="width: 45%;" />
+
+<p><span class="f2">S</span>ome sort of hammering woke them up. They looked about them in a daze.
+It was broad daylight, and things looked queer in the laboratory.
+There was a smell of scorched rubber and hot oil. Great loops of wire
+sagged down from above. Several nondescript heaps stood about that
+might once have been machinery, but now suggested melting snow-men,
+all fused into heaps. At a table sprawled a queer, misshapen figure
+that suggested human origin. Both of its hands were burned to cinders
+to the elbows. Great holes were scorched into the clothes. But the
+face was recognizable. Tony's playthings had got him at last.</p>
+
+<p>"Looks like something's happened in here!" Phil gasped, in amazement.</p>
+
+<p>"I'll bet it has, too," Ione exclaimed. "This is the first time it
+occurred to me that our recoil from throwing the safe overboard and
+the oscillation of our space-segment must have created a tremendous
+electrical field in the tetra-ordinate apparatus. The reaction is
+reversible, you see. The field swings the space-segment, or the
+swinging of the space-segment creates the field. And the field was too
+much for Tony."</p>
+
+<p>At this point the door fell under the blows of the police, and the
+raiding squad rushed into the room.</p>

+
+
+
+
+[Sidenote: In their pursuit of an unscrupulous scientist, Phil and
+Ione are swung into hyperspace--marooned in a realm of strange sights
+and shapes.]
+
+
+Tony Costello leaned glumly over his neat, glass-topped desk, on which
+a few papers lay arranged in orderly piles. Tony was very blue and
+discouraged. The foundations of a pleasant and profitable existence
+had been cut right out from under him. Gone were the days in which the
+big racket boss, Scarneck Ed, generously rewarded the exercise of
+Tony's brilliant talents as an engineer in redesigning cars to give
+higher speed for bootlegging purposes, in devising automatic electric
+apparatus for handling and concealing liquor, in designing
+beam-directed radios for secret communication among the gangs. Yes,
+mused Tony, it had been profitable.
+
+Six months ago the Citizens' Committee had stepped in. Now the police
+department was reorganized; Scarneck Ed Podkowski was in jail, and his
+corps of trusty lieutenants were either behind the bars with him or
+scattered far and wide in flight. Tony, always a free spender, had
+nothing left but the marvelous laboratory and workshop that Scarneck
+Ed had built him, and his freedom. For the police could find nothing
+legal against Tony. They had been compelled to let him alone, though
+they were keeping a close watch on him. Tony's brow was as dark as the
+mahogany of his desk. He did not know just how to go about making an
+honest living.
+
+With a hand that seemed limp with discouragement, he reached into his
+pocket for his cigarette-case. As he drew it out, the lackadaisical
+fingers failed to hold it firmly enough, and it clattered to the floor
+behind his chair. With the weary slowness of despondence, he dragged
+himself to his feet and went behind his chair to pick up the
+cigarette-case. But, before he bent over it, and while he was looking
+fully and directly at it, his desk suddenly vanished. One moment it
+was there, a huge ornament of mahogany and glass; the next moment
+there was nothing.
+
+ * * * * *
+
+Tony suddenly went rigid and stared at the empty space where his desk
+had stood. He put his hand to his forehead, wondering if his financial
+troubles were affecting his reason. By that time, another desk stood
+in the place.
+
+Tony ran over this strange circumstance mentally. His mental processes
+were active beneath, though dazed on the surface. His desk had stood
+there. While looking fully at it, all his senses intact, he had seen
+it vanish, and for a moment there had been nothing in its place. While
+he stared directly at the empty space from which the desk had
+disappeared, another desk had materialized there, like a flash.
+Perhaps, there had been a sort of jar, a tremor, of the floor and of
+the air, of everything. But the point was that his own desk, at which
+he had been working one moment, had suddenly vanished, and at the next
+moment another desk had appeared in its place.
+
+And what a desk! The one that now stood there was smaller than his own
+palatial one, and shabbier. A raw, unpleasant golden-oak, much
+scratched and scuffed. Its top was heaped and piled full of books and
+papers. In the middle of it stood a photograph of a girl, framed in
+red leather. Irresistibly, the sunny beauty of the face, the bright
+eyes, the firm little chin, the tall forehead topped by a shining mass
+of light curly hair, drew Tony's first glance. For a few moments his
+eyes rested delightedly on the picture.
+
+In a moment, however, Tony noticed that the books and papers on the
+desk were of a scientific character; and such is the nature of
+professional interest, that for the time he forgot his astonishment at
+how the desk had got there, in his absorption in the things heaped on
+top of it.
+
+Perhaps it isn't fair to give the impression that the desk was in
+disorder. It was merely busy; just as though someone who had been
+deeply engaged in working had for the moment stepped away. There was a
+row of books across the back edge, and Tony leaned over eagerly to
+glance at the titles.
+
+"'Theory of Parallels,' Lobatchevsky; 'Transformation of Complex
+Functions,' Riemann; 'Tensors and Geodesics,' Gauss," Tony read.
+"Hm--old stuff. But here's modern dope along the same line. 'Tensors,'
+by Christoffel; 'Absolute Differential Calculus,' by Ricci and Levi
+Civita. And Schroedinger and Eddington and D'Abro. Looks like
+somebody's interested in Relativity. Hm!"
+
+ * * * * *
+
+He bent over, his constantly increasing interest showing in the
+attitude of his body; he turned over papers and opened notebooks
+crowded full of handwritten figures. Last of all he noted the batch of
+manuscript directly in front of him in the middle of the front edge of
+the desk. It was typewritten, with corrections and interlineations all
+over it in purple ink.
+
+A title, "The Parallel Transformations of Equations for Matter,
+Energy, and Tensors," had been crossed out with purple ink, and "The
+Intimate Relation between Matter and Tensors" substituted. Tony bent
+over it and read. He was so fascinated that it did not even occur to
+him to speculate on the happy circumstance that the mysteriously
+appearing desk had brought its own scientific explanation with it. The
+title of the paper told him that its sheets would elucidate the
+apparently supernatural phenomenon, and all he did was to plunge
+breathlessly ahead in his eager reading. The article was short, about
+seven typewritten sheets. He took out his pencil and followed through
+the mathematical equations readily. Tony's mind was a brilliant, even
+though an erring one.
+
+Under the first article lay a second one. One glance at the title
+caused Tony to stiffen. Then he picked up the typewritten script and
+carried it across the big room of his laboratory, as far away from the
+desk as he could get. He put the girl's photograph in his pocket. Then
+he took heaps and armfuls of papers, books and notes and carried them
+from the desk to a bench in the far corner. For, as soon as he had
+read the title, "A Preliminary Report of Experimental Work in the
+Physical Manipulation of Tensors," a sudden icy panic gripped his
+heart lest the desk and its papers suddenly disappear before he had
+finished reading to the end of the fascinating explanation.
+
+We might add that it did not. For many weeks the desk remained
+standing in Tony's shop and laboratory, and he had the opportunity to
+study its contents thoroughly. But it took him only a few hours to
+grasp its secret, to add his own brilliant conception to it, and to
+form his great resolve. Once more Tony faced the world hopefully and
+enthusiastically.
+
+
+PART II
+
+_Vanishing Valuables_
+
+The police understood Tony's share in the exploits of Scarneck Ed
+thoroughly, and, chagrined at their failure to produce proof that
+would hold in court, they maintained a close and constant watch on
+that gifted gentleman long after crime matters in the city seemed to
+have been cleaned up and forgotten. For one thing, they still had
+hopes that something would turn up to enable them to round off their
+work and lock him up with his former pals; for another, they did not
+fully trust his future behavior. Nevertheless, for three or four
+months it seemed as though Tony had genuinely reformed. He lived in
+and for his laboratory and shop. All day the scouts could see him
+laboring therein, and far into the night he bent over benches and
+machines under shaded lights. Then, some other astonishing occurrences
+distracted their attention from Tony to other fields.
+
+One morning Mr. Ambrose Parakeet, private jewel broker, walked briskly
+out of the elevator on the fourteenth floor of the North American
+Building and unlocked the door of his office. He flung it open and
+started in, but stopped as if shot, uttered a queer, hoarse gurgle,
+and staggered against the door-casing. In a moment he recovered and
+began to shout:
+
+"Help! Help! Robbers!"
+
+Before long, several people had gathered. He stood there, gasping,
+pointing with his hand into the room. The eagerly peering onlookers
+could see that beside his desk stood an empty crate. It was somewhat
+old and weatherbeaten and looked as though it might have come from a
+buffet or a bookcase. He stood there and pointed at it and gasped, and
+the gathering crowd in the corridor wondered what sort of strange
+mental malady he had been seized with. The elevator girl, with trained
+promptness had at once summoned the manager of the building, who
+elbowed his way through the crowd and stood beside Mr. Parakeet.
+
+ * * * * *
+
+"There! There! Look! Where is it?" Mr. Parakeet was gasping slowly and
+gazing round in a circle. He was a little gray man of about sixty, and
+seemed utterly dazed and overcome.
+
+"What's wrong, Mr. Parakeet?" asked the building manager. "I didn't
+know you had your safe moved out."
+
+"But, no!" panted the bewildered old man. "I didn't. It's gone. Just
+gone. Last night at five o'clock I locked the office, and it was
+there, and everything was straight. What did you do? Who took it?"
+
+The building manager conducted the poor old man into the office, shut
+the door, and asked the crowd to disperse. He sat Mr. Parakeet down
+into the most comfortable chair he could find, and then barked
+snappily into the telephone a few times. Then he sat and stared about
+him, stopping occasionally to reassure the old man and ask him to be
+patient until things could be investigated.
+
+The building manager was an efficient man and knew his building and
+his tenants. He knew, as thoroughly as he knew his own office, that
+Mr. Parakeet had a medium-sized A. V. & L. Co.'s safe weighing about
+three tons, that could not be carried up the elevator when Mr.
+Parakeet had moved in, and had been hoisted into the window with block
+and tackle. He knew that it was physically impossible for the safe to
+go down any of the elevators, and knew that none of the operators
+would dare move any kind of a safe without his permission.
+Nevertheless, with the aid of a police-sergeant, his night-shift, and
+the night-watchmen of his building and adjacent ones, it was
+definitely established that nothing had been moved in or out of the
+North American Building during the preceding twenty-four hours, either
+by elevator or through a window to the sidewalk.
+
+ * * * * *
+
+The newspapers took up the mystery with a shout. The prostrating loss
+suffered by Mr. Parakeet, amounting to over a hundred thousand
+dollars, added no little sensation to the story. A huge safe,
+disappearing into thin air, without a trace, and in its place an old
+wooden crate! What a mouthful for the scareheads! For several days
+newspapers kept up items about it, dwindling in size and strategic
+importance of position; for nothing further was ever found. Every bit
+of investigation, including that by scientific men from the University
+of Chicago, was futile; not a trace, not a suggestion did it yield.
+
+Six days later the tall scareheads leaped out again: "Another Safe
+Disappears! Absolutely No Trace! Some time during the night, the
+six-foot steel safe of the Simonson Loan Company vanished into thin
+air. In the morning a dilapidated iron oil-cask was found in its
+place. The safe was so large and heavy that it could not have been
+moved without a large truck, special hoisting apparatus, a crew of
+men, and some hours of time. The store was brightly lighted during the
+entire night, and two watchmen patrolled it regularly. They report
+that they saw and heard nothing unusual, and were very much amazed
+when shown the oil-cask standing where the safe had been the night
+before." The accounts in the various papers were substantially the
+same.
+
+Newspaper readers throughout the city and its environs were very much
+intrigued. Such a thing was very exciting and mystifying; but it was
+so far out of touch with their own lives that it did not affect them
+very much at any time except when they were reading the paper or
+discussing it in conversation. The police were the ones who were doing
+the real worrying. And, when the following week two more safes
+disappeared, insurance companies began to take an interest in the
+matter; and everyone who had any considerable amount of valuables in
+store began to feel panicky.
+
+ * * * * *
+
+The circumstances surrounding the disappearance of the last of the
+series, the fourth, were especially amazing. This was also a jewelry
+safe. Canzoni's is a popular firm that rents a quarter of a floor in a
+big department store, and does a large volume of moderate-priced
+business. The receipts are stored in a heavy portable safe in a corner
+of the silverware section until evening, when they are carried to the
+large vault of the big store. One Saturday afternoon after a
+particularly busy day, Mr. Shipley, Canzoni's manager, was watching
+the hands of the clock creep toward five-thirty. He leaned on a
+counter and watched the clerks putting away goods for the night; he
+glanced idly toward the safe which he intended to open in a few
+minutes. The doormen had already taken their stations to keep out
+further customers. Then he glanced back at the safe, and it wasn't
+there!
+
+Mr. Shipley drew a deep breath. The safe disappearances he had read
+about flashed through his mind. But he didn't believe it. It couldn't
+be! Yet, there was the empty corner with the birch panels forming the
+back of the show-windows, and no safe. In a daze, he walked over to
+the corner, intending to feel about with his hands and make sure the
+safe was really gone. Before he got there, there flashed into sight in
+place of the safe, a barrel of dark wood; and in a moment there was a
+strong odor of vinegar.
+
+Things spun around with Mr. Shipley for a few moments. He grasped a
+counter and looked wildly about him. Clerks were hurrying with the
+covering of counters; no one seemed to have noticed anything. He stood
+a moment, gritted his teeth, and breathed deeply, and soon was master
+of himself. He stood and waited until the last customer was gone, and
+then called several clerks and pointed to where the safe had stood.
+
+Within the space of a month, thirteen safes and three million dollars
+worth of money or property had disappeared. The police were dazed and
+desperate, and business was in a panic. Scientific men were appealed
+to, to help solve the riddle, but were helpless. Many of them agreed
+that though in theory such things were explainable, science was as yet
+far from any known means of bringing them about in actuality.
+Insurance companies spent fabulous sums on investigation, and, failing
+to get results, raised their premiums to impossible levels.
+
+
+PART III
+
+_The Lady of the Picture_
+
+Phil Hurren, often known as "Zip" Hurren, reporter on the _Examiner_,
+felt, on the day the managing editor called him into the sanctum, that
+fortune could smile on him no more brightly. There wasn't anything
+brighter.
+
+"You stand well with the detective bureau," his boss had said; "and
+you've followed this safe-disappearing stuff pretty closely. You're
+relieved of everything else for the time being. Get on that business,
+and see that the public hears from the _Examiner_!"
+
+Phil knew better than to say any more, for before he recovered from
+his surprise, the editor had turned his back, buried himself in his
+work on the desk, and forgotten that Phil was there. Nor did Phil
+waste any real time in rejoicing. That is why he was called "Zip."
+When things happened, whether it was luck or system, Phil was usually
+there. In sixty seconds more, Phil was in a taxicab, whirling toward
+police headquarters.
+
+Luck or system, he didn't know, but he struck it again. The big wagon
+was just starting away from the station door when he arrived, crowded
+inside with bluecoats and plainclothes-men. The burly, red-faced man
+with chevrons on his sleeve, sitting beside the driver, saw Phil jump
+out, and motioned with his hand. Phil leaped up on the back step of
+the vehicle and hung on for dear life with his fingers through the
+wire grating as they careened through the streets. The men on the
+inside grinned at him; a number of them knew him and liked him.
+Gradually the door was opened and he crowded in. He found Sergeant
+Johnson and eyed him mutely.
+
+"How the hell do you find these things out, I'd like to know," the
+sergeant exclaimed. "Are you a mind-reader?"
+
+"I don't really know anything," Phil admitted with that humility which
+the police like on the part of newspaper men and seldom meet with. "Do
+you mind?"
+
+"No objection," grunted the sergeant. "Been watching all the old
+crooks since these safes have been popping. Nothin' much on any of
+them, except this slippery wop, Tony Costello. No, we haven't caught
+him at anything. Seems to be keeping close and minding his own
+business. Working in his laboratory. Ought to make a good living if he
+turned honest; clever guy, he seems. But he's been too prosperous
+lately. Lots of machinery delivered to his place; we traced it to the
+manufacturers and find it cost thousands. Big deposits in his banks.
+But, no trace of his having sold anything or worked at anything
+outside his own place. So, we're running over to surprise him and help
+him get the cobwebs out of his closets."
+
+ * * * * *
+
+The raid on Tony Costello's shop and laboratory disclosed nothing
+whatever. They surrounded the place effectively and surprised Tony
+genuinely. But a thorough search of every nook and cranny revealed
+nothing whatever of a suspicious nature. There was merely a tremendous
+amount of apparatus and machinery that none of the raiding party
+understood anything about. Tony's person was also thoroughly searched,
+and the leather-framed photograph of the beautiful unknown girl was
+found.
+
+"Who's this?" the sergeant demanded. "She don't look like anyone that
+might belong to your crowd."
+
+"I don't know," Tony replied.
+
+"Whad'ya mean, don't know?" The sergeant gave him a rough shake.
+"What'ya carryin' it for, then?"
+
+"I had really forgotten that it was in my pocket," Tony replied
+calmly, at his ease. "I found it in a hotel room one day, and liked
+the looks of it."
+
+"I know you're lying there," the sergeant said, "though I'm ready to
+believe that you don't know her. Too high up for you. Well, it looks
+suspicious and we'll take the picture."
+
+"Boy!" gasped Phil. "What a girl she must be in person! Even the
+picture would stand out among a thousand. May I have the picture,
+Sergeant?"
+
+"You can come and get a copy of it to-morrow. We'll have it copied and
+see if we can trace the subject of it. That might tell us something."
+
+ * * * * *
+
+The following morning Phil was at Police Headquarters to pick up
+further information, and to get a copy of the girl's photograph. Like
+the police, he could not keep his mind off the idea that there was
+some association between the crooked engineer and the disappearance of
+the safes. It seemed to fit too well. The scientific nature of the
+phenomena, Tony Costello's well known reputation for scientific
+brilliance, and his recent affluence; what else could it mean? In some
+way, Tony was getting at these safes. But how? And how prove it? Most
+exhaustive searches failed to reveal any traces of the safes anywhere.
+If any fragment of one of them had appeared in New York or San
+Francisco, the news would have come at once, such was the sensation
+all over the country that the series of disappearances had caused.
+Tony's calm insolence during the raid, his attitude of waiting
+patiently till the police should have had their fun and have it over
+with so that he might be left at peace again, showed that he must be
+guilty, for anyone else would have protested and felt deeply injured
+and insulted. He seemed to be enjoying their discomfiture, and
+absolutely confident of his own safety.
+
+"There's got to be some way of getting him," Phil mused; and he mused
+almost absent-mindedly, for he was gazing at the photograph of the
+girl. For many minutes he looked at it, and then put it silently into
+his pocket.
+
+Five o'clock in the evening of that same day came the news of another
+safe disappearance. Phil got his tip over the phone, and in fifteen
+minutes was at the scene. It was too much like the others to go into
+detail about; a six-foot portable safe had suddenly disappeared right
+in front of the eyes of the office staff of The Epicure, a huge
+restaurant and cafeteria that fed five thousand people three times a
+day. In its place stood a ragged, rusty old Ford coupe body. He went
+away from there, shaking his head.
+
+Then suddenly in the midst of his dinner, he jumped up, and ran. An
+idea had leaped into his head.
+
+"Right after one of these things pops is the time to take a peek at
+Tony," he said to himself, and immediately he was on the way.
+
+ * * * * *
+
+But how to get his peep was not so easy a problem. When he alighted
+from his cab a block away from Tony's building, he was hesitant about
+approaching it. Tony knew him, and might see him first. Phil circled
+the brick building, keeping under cover or far enough away; all around
+it was a belt of thirty feet of lawn between the building and the
+sidewalk. Ought he have called the police and given them his idea? Or
+should he wait till darkness and see what he could do alone?
+
+Then suddenly he saw her. Across the street, standing in the shelter
+of a delivery truck in front of an apartment, she was observing Tony's
+building intently. The aristocratic chin, the brightness of the eyes,
+the waves of her hair, and the general sunny expression! It could not
+be anyone else. Post haste he ran across the street.
+
+"Pardon me!" he cried excitedly, lifting his hat and then digging
+hastily into his inner pocket. "I'm sure you must be the--"
+
+"Well, the nerve!" the young woman said icily, and pointing her chin
+at the opposite horizon she walked haughtily away.
+
+By that time Phil had dug out his picture and was running after her.
+
+"Please," he said, "just a moment!" And he held the picture out in
+front of her face.
+
+"Now, where in the world--?" She looked at him in puzzled and
+indignant inquiry, and then burst out laughing.
+
+"It _is_ you, isn't it?" Phil asked. "What are you laughing at?"
+
+"Oh, you looked so abject. I'm sure your intentions must be good. Now
+tell me where you got my picture."
+
+"Let us walk this way," suggested Phil, leading away from Tony's
+building.
+
+ * * * * *
+
+And, as they walked, he told her the story. When he got through she
+stood and looked at him a long time in silence.
+
+"You look square to me," she said. "You're working on my side already.
+Will you help me."
+
+"I'll do anything--anything--" Phil said, and couldn't think of any
+other way of expressing his willingness, for the wonderful eyes bore
+radiantly upon him.
+
+"First I must tell you my story," she began. "But before I can do so,
+you must promise me that it is to remain an absolute secret. You're a
+newspaper man--"
+
+Phil gave his promise readily.
+
+"My father is Professor Bloomsbury at the University of Chicago. He
+has been experimenting in mathematical physics, and I have been
+assisting him. He has succeeded in proving experimentally the concept
+of tensors. A tensor is a mathematical expression for the fact that
+space is smooth and flat, in three dimensions, only at an infinite
+distance from matter; in the neighborhood of a particle of matter,
+there is a pucker or a wrinkle in space. My father has found that by
+suddenly removing a portion of matter from out of space, the pucker
+flattens out. If the matter is heavy enough and its removal sudden
+enough, there is a violent disturbance of space. By planning all the
+steps carefully my father has succeeded in swinging a section of
+space on a pivot through an angle of 180 degrees, and causing two
+portions of space to change places through hyperspace, or as you might
+express it popularly, through the fourth dimension."
+
+ * * * * *
+
+Phil held his hands to his head.
+
+"It is not difficult," she went on smiling. "Loan me your pocket knife
+and a piece of paper from your notebook. If I cut out a rectangular
+piece of paper from this sheet and mount it on a pivot or shaft at A
+B, I can rotate it through 180 degrees, just like a child's
+teeter-totter, so that X will be where Y originally was. That is in
+two dimensions. Now, simply add one dimension all the way round and
+you will have what daddy is doing with space. He does it by shoving
+fifty or a hundred pounds of lead right out of space; the sudden
+flattening out of the tensors causes a section of space to flop
+around, and two portions of space change places. The first time he
+tried it, his desk disappeared, and we've never seen it again. We've
+thought it was somewhere out in hyperspace; but this terrible story of
+yours about disappearing safes, and the fact that you have this
+picture, means that someone has got the desk."
+
+"Surely you must have suspected that long ago, when the disappearances
+first began?" Phil suggested.
+
+"I've just returned from Europe," said Miss Bloomsbury. "I was
+tremendously puzzled when I got my first newspapers in New York and
+read about the safes. Gradually I gathered all the news on the
+subject, and it seemed most reasonable to suspect this gangster
+engineer."
+
+"Great minds and same channels," Phil smiled. "But your father. Why
+didn't he speak up when the safes began to pop?"
+
+"Ha! ha!" she laughed a tinkly little laugh. "My father doesn't know
+what safes are for, nor who is President, nor that there has been a
+war. Mother and I take care of him, and he works on tensors. He has
+probably never heard about the safes."
+
+ * * * * *
+
+"What were you going to do around here?" Phil asked, marveling at the
+courage of the girl who had come to look the situation over
+personally.
+
+"I hadn't formed any definite plans. I just wanted to look about
+first."
+
+"Well," said Phil, "as you will soon see by the papers, another safe
+has puffed out. It occurred to me that we might find out something by
+spying about here immediately after one of the disappearances. That's
+why I'm here. If you'll tell me where you live, or wait for me at some
+safe place, I'll come and report to you as soon as I find out
+anything."
+
+"Oho! So that's the kind of a girl you think I am!" She laughed
+sunnily again. "No, Mr. Reporter. Either we reconnoiter together, or
+each on our own."
+
+"Oh, together, by all means," said Phil so earnestly that she laughed
+again. "And since we'd better wait for darkness, let's have something
+to eat somewhere. I didn't finish my dinner."
+
+Phil found Ione Bloomsbury in person to be even more wonderful than
+her photograph suggested. Obviously she had brains; it was apparent,
+too that she had breeding. Her cheerful view of the world was like a
+tonic for tired nerves; and withal, she had a gentle sort of courtesy
+in her manner that may have been old-fashioned, but it was almost too
+much for Phil. Before the dinner was over, he would have laid his
+heart at her feet. It gave him a thrill that went to his head, to have
+her by his side, slipping along through the darkness toward Tony's
+building.
+
+This building was a one-story brick affair with a vast amount of
+window space. From the sidewalk they could see faint lights glowing
+within, but could make out no further details. They therefore selected
+the darkest side of the building, and made their way hurriedly across
+the lawn. Here, they found, they could see the crowding apparatus
+within the one long room fairly well. They looked into one window
+after another, making a circuit around the building, until Phil
+suddenly clutched the girl's arm.
+
+"Look!" he whispered. "Straight ahead and a little to the left!"
+
+At the place he indicated stood a tall safe. Across the top of its
+door were painted in gold letters, the words: "The Epicure."
+
+"That's the safe that went to-night," whispered Phil. "That's all we
+need to know. Now, quick to a telephone!"
+
+"Oh," said a gentle, ironic voice behind them, "not so quick!"
+
+ * * * * *
+
+They whirled around and found themselves looking into two automatic
+pistols, and behind them in the light of the street lamps, the
+sardonic smile of Tony Costello.
+
+"Charmed at your kind interest in my playthings, I'm sure," he purred.
+"Only it leaves me in an embarrassing position. I'm not exactly sure
+what to do about it. Kindly step inside while I think."
+
+Phil made a move sidewise along the wall.
+
+"Stop!" barked Costello sharply. "Of course," his voice was quiet
+again, "that might be the simplest way out. I think I am within my
+legal rights if I shoot people who are trying to break into my
+property. Yet, that would be messy--not neat. Better step in. The
+window swings outward."
+
+At the point of his pistols they clambered through the window, and he
+came in after them. He kept on talking, as though to himself, but loud
+enough for them to hear.
+
+"Yes, we want some way out that is neater than that. Hm! Violence
+distresses me. Never liked Ed's rough methods. Yet, this is
+embarrassing."
+
+He turned to them.
+
+"What did you really want here? I see that you are the _Examiner's_
+reporter, and that you are the lady of the photograph. What did you
+come here for? Ah, yes, the safe. Well, go over and look at it."
+
+As they hesitated, he stamped his foot and shrilled crankily:
+
+"I mean it! Go, look at the safe! Is there anything else you want to
+know?"
+
+"Yes," said Phil coolly, his self-control returning, "where are the
+other safes?"
+
+"Oh. Anything to oblige. Last requests are a sort of point of honor,
+aren't they. Ought to grant them. Stand close to that safe!"
+
+ * * * * *
+
+He backed away, his guns levelled at them. He laid down the right one,
+keeping the left one aimed, and moved some knobs on a dial and threw
+over a big switch. A muffled rumbling and whirring began somewhere;
+and then, slowly, a block of tables and apparatus ten feet square rose
+upward toward the ceiling. A section of the floor on which they stood
+came up, supported by columns, and now formed the roof of a room that
+had risen out of the floor. In it were four safes.
+
+"Poor old Ed!" sighed Tony. "There was a time when he had a lot of
+good stuff put away down there. I've got six rooms like that. Well,
+the good old times are over."
+
+He threw out the switch and the whole mass sank slowly and silently
+downward till the floor was level and there was no further sign of it.
+Then he backed away to another table, across the room from them,
+keeping his gun levelled.
+
+"Too bad," he said. "I don't like to do these things. But--" he sighed
+deeply, "self-preservation. Now I'm going to flip you out, yes,
+_out_, into a strange region. I've never been there. I don't know if
+there is food or drink there. I hope so, for you'll never get back
+here."
+
+Phil stiffened. He determined to leap and risk a shot. But he was too
+late. Tony's hand came down on a switch. There was a sudden,
+nauseating jar. The laboratory vanished.
+
+There was only the safe, Ione Bloomsbury and himself, and a small
+circle of concrete floor extending to a dim little horizon a dozen
+feet away. Beyond that, nothing. Not blue, as the sky is. Not black,
+as dark, empty spaces are. It suggested black, because there was no
+impression of light or color on the eyes; but it wasn't black. It was
+nothingness.
+
+
+PART IV
+
+_Marooned in Hyperspace_
+
+"I suppose you realize what he has done?" Miss Bloomsbury inquired.
+
+"Couldn't be too sure, but it looks like plenty. What's the equation
+for it?" Beneath his jocularity, Phil felt a tremendous sinking within
+him. It looked serious, despite the fact that he did not understand it
+at all.
+
+"He has swung us out into hyperspace, or into the fourth dimension, as
+your newspaper readers might understand it, and has let us hang there.
+Remember our slip of paper. Suppose X and Y were swung out of the
+plane of the paper and allowed to remain at an angle with it. We are
+at an angle with space, out in hyperspace."
+
+There was a period of bewilderment, almost panic, in which they both
+felt so physically weak that they had to sit down on the concrete and
+stare at each other mutely. But this passed and their natural courage
+soon reasserted itself. Their first thought was to take stock of what
+information they could get on their situation; and their first step
+was to venture as close as possible to the queer little horizon which
+lay almost at their very feet. It gave them a frightened feeling, as
+though they were standing high up on a precipice or tower.
+
+To their surprise, the horizon receded as they walked toward it,
+always remaining about a dozen feet away from them. At first they
+walked on concrete and then came to a crumbly edge of it and found
+themselves stepping on hard, sandy earth. Later there was rock,
+sometimes granite-like, sometimes black and shiny. But what they saw
+underfoot was nothing, compared with the glimpses of things they got
+out in the surrounding emptiness. First there was a vast space in
+which a soft light shone, and in which there were countless spheres of
+various sizes, motionlessly suspended. The spheres seemed to be made
+of wood, a green, sap-filled, unseasoned wood. The scene was visible
+for a few seconds, and vanished suddenly as they walked on. This
+astonished them; so they stepped back a pace or two and saw it again;
+and as they moved on, it disappeared again.
+
+ * * * * *
+
+Then there was a great stretch of water in which the backs of huge
+monsters rolled and from which a hot wind blew for a few instants
+until they passed on and the scene vanished. There was a short walk
+with nothing but emptiness, and then there appeared huge, oblique,
+cubistic looking rows of jagged rocks in wild, dizzy formations that
+didn't look possible; and farther on, after another interval of
+emptiness, a tangle of brown, ropey vines with black-green leaves on
+them, an immense space filled with serpentine swinging loops and
+lengths of innumerable vines. Several loops projected so near them
+that they could have reached out and touched them had they wished.
+
+"This is too much for me!" Phil gasped. "Have we gone crazy? Or did
+he kill us, and is this Purgatory?"
+
+Ione smiled and shook her little head in which she had a goodly store
+of modern mathematics stored away.
+
+"These must be glimpses of other 'spaces' besides our own space. If we
+could see in four dimensions we could see them all spread out before
+us. But we can only perceive in three dimensions; therefore, as we
+walk through hyperspace, past the different 'spaces' which are ranged
+about in it, we get a glimpse into such of them as are parallel with
+our own space. Can you understand that?"
+
+"Oh, yes," groaned Phil. "It sounds just about like it looks. But,
+don't mind me. Go on, have your fun."
+
+"I've been thinking about those wooden spheres," continued Ione. "I'm
+sure they must be sections of trees that are cut crosswise by our
+'space;' they grow in three dimensions, but only two of them are our
+dimensions and a third is strange to us. We see only three-dimensional
+sections of them, which are spheres. There is more of them, that we
+cannot see, in another dimension."
+
+"Yes, yes. Just as plain as the Jabberwock!"
+
+"Look! There's a real Jabberwock!" exclaimed Ione.
+
+On ahead of them they saw a number of creatures that seemed to be made
+of painted wooden balls in different colors, joined together.
+
+"Tinkertoys!" exclaimed Phil. "Live ones! Big ones!"
+
+The animals, though they looked for all the world as though they were
+made of painted wood, moved with jerky motions and clattered and
+snarled.
+
+"There is probably more to _them_ in another dimension," Ione said.
+
+ * * * * *
+
+Suddenly one of the beasts approached them with a leap. There were two
+big eyes and two rows of teeth that came together with a snap, right
+on Phil's trouser-leg. He jerked himself away, sacrificing some square
+inches of trouser-leg, and, whirling around, kicked at the thing with
+all his force. It almost paralyzed his foot, for the animal seemed to
+be made of wood or bone. But it disappeared, and, as it did, both of
+them felt a queer, nauseating jolt. A few more minutes' walk brought
+them back to the safe without seeing any more spaces; and the sight of
+its black iron bulk filled them with a home-like relief, which in a
+moment they recognized as a mockery.
+
+"Are we on a sphere of some sort?" Phil asked.
+
+"Probably on an irregular mass of matter," Ione replied, "part of
+which is Tony's concrete floor, and part of which comes out of some
+other dimension. This mass of matter is at one end of a long, bar-like
+portion of space, the middle of which is pivoted in our world,
+somewhere in Chicago, and both ends of which are free in hyperspace."
+
+"Then," suggested Phil, "why can't we walk down to the axle on which
+it is balanced, and step out into Chicago?"
+
+"Because there isn't any _matter_ for us to walk on. We are not able
+to move about in space, in three dimensions, you know. We can only get
+around in two dimensions, on the surface of _matter_."
+
+"Well, let's try another exploration trip at right angles to our first
+one. After all, these 'spaces' are an interesting show, and I want to
+see some more."
+
+They started out in the selected direction, and after a short walk got
+a glimpse of a vast space dotted with stars and nebulae, with two
+bright moons sailing overhead. A few steps farther on was a wall of
+solid granite, near enough to touch with their hands. Again, there was
+an intensely active mass of weaving bright stripes and loops and
+circles, seeming to consist of light only, and making them dizzy in a
+few seconds. Ione wondered if it might not be something like an
+organic molecule on a large scale. Again, odd, queer, indescribable
+shapes and outlines would appear and disappear, obviously
+three-dimensional sections of multi-dimensional things, cut by space.
+Once they passed a place of intense cold and terrific noise and
+escaped destruction or lunacy only because it took them the merest
+instant to get past.
+
+They arrived back at the safe, very much fatigued from the strain,
+their minds woefully confused. Hunger and thirst were beginning to
+thrust up their little reminders; and for the first time the terrors
+of their position, flung out into hyperspace on a small, barren piece
+of matter, began to seem real.
+
+ * * * * *
+
+After a rest they started out again. As Phil had touched, in kicking
+it, a creature from another "space," perhaps they might find water and
+even food somewhere. They retraced their first steps to the spot where
+they had at first seen water. They found it again and were able to dip
+their hands into it. It was warm, and too salty to drink. They came to
+the place with the creepers or vines, and Phil reached out and seized
+one of them. It was heavy, rubbery, and elastic, stretching readily as
+he pulled it.
+
+"These little lurches that we feel must be the snapping back of the
+space-puckers as expressed by tensors," Ione remarked. "Every time
+matter goes in or out of space, the nature of space is altered."
+
+"Well," observed Phil, releasing the vine, "I'd better be careful. If
+one of these things hauls me off here, our last bond with home is
+gone. I don't want to get lost in some other space."
+
+As he released the vines they snapped back to their places, and the
+forest of them dimmed a little and reappeared.
+
+They made the round again, dodging cautiously past the point where
+they had previously found the "Tinkertoy" animals, and succeeded in
+getting past their snapping teeth. But no promise of food or water did
+they find anywhere.
+
+"Looks like we're sunk," observed Phil, as they dropped down on the
+concrete to rest, leaning their backs against the safe.
+
+How time counted in hyperspace, neither Phil nor Ione could tell; Phil
+knew that his watch was running. He knew that it was ages and ages
+that he sat with his back against the safe, reviewing all the events
+of his put life, and thinking of this ignominious end to a lively
+career! He swore half aloud; then suddenly looked at Ione, ready to
+apologize. He found her weeping silently.
+
+"I should never have let you come into the building with me," he
+stammered in confusion at her tears.
+
+"Oh, what do I care what becomes of _me_!" she exclaimed angrily. "But
+who will take care of poor daddy? He doesn't even know when it's time
+to eat." And she burst into a fresh fit of weeping.
+
+Phil bent his head in the dumbness of profound despair.
+
+
+PART V
+
+_The Reversible Equation_
+
+Despair, however, is a luxury. Necessity is a stimulus. With the
+parchings of thirst and the gnawings of hunger, the two young people
+ceased swearing and weeping. Phil got up and paced about and sat down
+again. Ione's tears stopped and dried, and she sat and thought.
+
+In the back of her mind there had been forming a vague sort of an
+idea, which had signalled ahead of itself that there was hope. She sat
+there and desperately drove her reason to its utmost efforts, to find
+that idea and bring it to the surface of consciousness. Hand to hand
+fights with wild animals, battles between ships of the line, vicious
+duels between ace-aviators in the clouds are tense fights; but they
+cannot compare in anxious difficulty with the struggle to bring up an
+unformed idea out of the subconscious mind--especially when one knows
+that the idea is there, and that it must be found to save one's life.
+
+"Ione!" exclaimed Phil. It was the first time he had used the name.
+"What is the matter? You are as tense as a--"
+
+"Ah!" cried Ione, springing up. "Tense! Tensors! I have it!"
+
+Phil gazed at her in alarm. She laughed; at first it was a strained
+laugh, but gradually it melted into her sunny one.
+
+"No, I'm not crazy. I knew there was a way out, and I've been trying
+to reason it out. How simple. You remember the little jolts when you
+pulled at the vines and when you kicked the funny animal? Tensors.
+Matter and space are so closely interrelated that you can't move
+matter in or out of space without causing disturbance, recoils, and
+tremors in space. Those bits of matter were small, and produced only a
+slight disturbance. It takes about a hundred pounds of lead to swing
+this segment--"
+
+"Oho! Got you!" exclaimed Phil. "Not so dumb! The safe!"
+
+"Yes. The safe!" Ione cried.
+
+"Throw it off and watch us swing, eh? What would happen?"
+
+"I might calculate it if I knew the weight of the safe."
+
+"No calculating when I'm around," Phil said. "It couldn't make things
+any worse. Try it first and calculate afterwards."
+
+ * * * * *
+
+They got behind the safe and pushed, and their combined strength
+against it was about as effective as it would have been in moving the
+Peoples' Gas Building. They sat down again in despair.
+
+"Suppose we _could_ budge it," Ione said. "All we could do would be to
+push it around, this piece of matter we are on. That wouldn't help.
+We've got to get it out of space. We can't push it hard enough to do
+that. It's got to be shot out suddenly--"
+
+"And we haven't got a gun handy," Phil remarked droopingly.
+
+"Not exactly a gun. A sort of sling--"
+
+Phil leaped to his feet.
+
+"A sling. Why! To be sure! The vines!"
+
+Without another word, both of them got up and ran. They hastened in a
+direction opposite to the one they had at first taken on their trip of
+exploration, and this brought them first past the "space" of the
+Tinkertoy-like animals. As they went by, several of these beasts
+darted at them, one of them snapping at Ione's heels. She uttered a
+scream, causing Phil to turn about and kick right and left among them.
+He drove them back and escaped from them, rejoining Ione.
+
+"Wait," he said, when they reached the vines. "Remember those wooden
+balls. If I could get a few to throw at those critters--"
+
+In a moment they were off, and finally arrived at the point from which
+they first saw the balls. Odd it seemed, how they hung suspended in
+space, thousands of them, all sizes. Phil reached out and grasped one
+about the size of a baseball and drew it toward himself. He felt a
+dizzy lurch and heard Ione scream.
+
+"Let go!" she screamed again.
+
+When he suddenly realized what was going on, he found himself
+prostrate on the ground, with Ione across him, her arms about his
+knees.
+
+"Do you realize," she panted, disentangling herself, "that you were
+pulling yourself out of this space into that one?"
+
+"Thanks!" said Phil. "Never say die. More careful this time, and a
+smaller one."
+
+ * * * * *
+
+He reached out and grasped a ball smaller than a golf-ball, and pulled
+carefully, keeping an eye upon Ione. There was resistance to his pull,
+but gradually the ball came. It seemed heavy. There was a crack as of
+breaking wood, and he fell backward, with a wave of nausea sweeping
+strongly over him. He gazed in amazement at a heavy wooden stick that
+he held in his hands. The only thing about it that suggested the ball
+for which he had reached was its diameter.
+
+"Can't understand it, but appreciate it just the same," he said. He
+broke the stick in two, and had two excellent clubs.
+
+"Simple," Ione replied. "The balls are cross-sections of these trees
+or sticks which grow in a 'space' at right angles to our own; and we
+only see their three-dimensional cross-sections."
+
+"Yes," said Phil. "Cabbages and kings. I'm for you and the party."
+
+A short walk brought them to the "space" of the vines. After testing
+the matter out carefully, they found that they could each pull two of
+them at a time. The vines stretched amazingly when they found those
+whose far ends were fixed firmly in the tangle, permitting them to
+carry their own ends along with them toward the safe. Phil wound his
+vines around his left arm and stuck one club through his belt. The
+other he got ready for the wooden animals.
+
+He needed it. The size of the pack was doubled, and he rapped them
+till his hand was numb before he and Ione got by. Their vines drew out
+thin, but held until they were firmly tied about the safe. They went
+back after four more.
+
+"I should judge," said Phil, "that by the time we get thirty or forty,
+the elastic pull will be strong enough to drag the safe back with
+them as they snap back home."
+
+ * * * * *
+
+Trip after trip they made, fighting the wooden animals with their
+clubs each time. Their clothes were torn, and their legs bleeding;
+their throats were dry and lips cracked. The hard animals seemed to
+have a persistent, mechanical ferocity that was undismayed by
+hammering with the clubs and by repeated repulses. Phil could not seem
+to hurt them; he merely knocked them away. Finally, on the ninth trip,
+Ione collapsed when she reached the safe. As she fell, the elasticity
+of the vines began slowly to drag her back with them. Phil was forced
+to sit across her knees while he tied his own vines about the safe.
+Then he released her and added her vines to the great cable about the
+safe.
+
+An overbold hard animal rattled up and snapped at her. Goaded to fury,
+Phil swung at it with his club and hurled it through the air. He could
+feel the lurch as it left his space and entered another. Then he
+pushed with his mightiest effort against the safe. It budged, and slid
+a few inches. He used his stick as a lever. It moved again, a little
+faster. Ione struggled to her feet and tried to help, but her efforts
+were ineffectual.
+
+With one arm about her, Phil pried again under the safe, knowing that
+another trip after vines was out of question. Another animal snapped
+at their heels. For a while, it was kick backwards, then a shove at
+the safe. Each time the safe moved. The sight of its movement revived
+Ione, so that she was able to push also. Gradually it acquired a
+steady motion, pulled by the contraction of the vines; its progress
+soon became faster and faster. Phil was about to follow it and give it
+another push, when Ione drew him back.
+
+Suddenly they experienced a sinking sensation and a fearful vertigo.
+The snapping animals faded. Ahead of them was the forest of vines, and
+they saw the safe hurled into it, crashing, plunging into the tangled
+mass. The whole view crumpled and moved upwards like a swirl of leaves
+in a wind, and then vanished with a snap.
+
+ * * * * *
+
+They were sick and dizzy, but tremendously curious to see everything.
+The water, the cubistic cliffs, the vast space full of balls, all
+curiously blurred, appeared in succession. There were blank spaces and
+then blurred sights of things which they did not recognize, never
+having seen them before. Then the dizziness and the nausea abated, and
+ahead of them was a vast yellow blue, a huge nebula, and in it were
+double-colored suns and ringed planets with swarms of moons; this
+glorious sight remained for many seconds, as they gazed at it in
+panting astonishment, half reclining on the concrete; and then it
+faded. Again the nausea came on; again the succession of blurred
+views. Eventually the myriad spheres, the water with the leviathans,
+the forest of vines, each succeeding scene grew more blurred. Their
+nausea was correspondingly increased, till they were forced to lie
+down on the ground from illness.
+
+When their giddiness abated, there were blurring views again. There
+was an impression as though the speed of a train were decreasing as
+one looks out of the window. And how one view held for several
+seconds, a vast and wild mountain-range with glaciers and snow peaks
+by moonlight. When this faded gradually, the scenes began to flick by,
+more and more rapidly, and grew blurred. Phil and Ione were attacked
+by nausea until, again, they had to lie down. After that came the
+familiar succession: the wooden animals, the tangle of vines, the vast
+sea, the spheres, and more blurred scenes. Then came a pause, with
+the nebula and the glorious suns swinging into view once again.
+
+"Oh, I understand!" Ione exclaimed; "We're swinging. The safe was so
+heavy that we swung too violently, too far, and back again--"
+
+"And we keep going till it knocks us out, or till the old cat dies,"
+added Phil.
+
+ * * * * *
+
+However, they found that after a number of repetitions of the same
+program, their giddiness was becoming less; and instead of lying down
+in the middle of the swing, they could look about. Then it occurred to
+Phil to time the interval between the nebula and the mountain-range.
+When the exact halfway point was determined, and after several more
+swings, they could see dimly the windows and machinery of Tony's
+laboratory flash by when they passed the middle.
+
+"I don't mean to be a crepe-hanger, but how do you know we will stop
+at the right point?" Phil asked.
+
+"I don't," replied Ione cheerfully. "But mathematics says so. A freely
+oscillating segment of space would naturally come to equilibrium in a
+position parallel to the rest of its own space, would it not?"
+
+There came a swing when they did not reach the nebula on the one hand
+and the mountain-range on the other. After that, views dropped off
+from either end of the swing quite rapidly, and before many minutes,
+they looked into Tony's laboratory a large portion of the time. For
+many seconds the laboratory held; then it would gradually fade, and
+reappear again, only to fade into empty nothingness all around.
+
+"The old cat's dead," Phil finally announced.
+
+They sat and stared about them as the laboratory held steady and no
+further intervening periods of blankness intervened. They both sighed
+deeply and slumped over on the ground to rest.
+
+"Bang! bang! bang!"
+
+ * * * * *
+
+Some sort of hammering woke them up. They looked about them in a daze.
+It was broad daylight, and things looked queer in the laboratory.
+There was a smell of scorched rubber and hot oil. Great loops of wire
+sagged down from above. Several nondescript heaps stood about that
+might once have been machinery, but now suggested melting snow-men,
+all fused into heaps. At a table sprawled a queer, misshapen figure
+that suggested human origin. Both of its hands were burned to cinders
+to the elbows. Great holes were scorched into the clothes. But the
+face was recognizable. Tony's playthings had got him at last.
+
+"Looks like something's happened in here!" Phil gasped, in amazement.
+
+"I'll bet it has, too," Ione exclaimed. "This is the first time it
+occurred to me that our recoil from throwing the safe overboard and
+the oscillation of our space-segment must have created a tremendous
+electrical field in the tetra-ordinate apparatus. The reaction is
+reversible, you see. The field swings the space-segment, or the
+swinging of the space-segment creates the field. And the field was too
+much for Tony."
+
+At this point the door fell under the blows of the police, and the
+raiding squad rushed into the room.

+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.

+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+https://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org. Email contact links and up to date contact

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
