“What’s the good in Einstein, anyhow?”

I shot the question at lean young Charlie King. In a moment he looked up at me; I thought there was pain in the back of his clear brown eyes. Lips closed in a thin white line across his wind-tanned face; nervously he tapped his pipe on the metal cowling of the _Golden Gull’s_ cockpit.

“I know that space is curved, that there is really no space or time, but only space-time, that electricity and gravitation and magnetism are all the same. But how is that going to pay my grocery bill--or yours?”

“That’s what Virginia wants to know.”

“Virginia Randall!” I was astonished. “Why, I thought--”

“I know. We’ve been engaged a year. But she’s called it off.”

Charlie looked into my eyes for a long minute, his lips still compressed. We were leaning on the freshly painted, streamline fuselage of the Golden Gull, as neat a little amphibian monoplane as ever made three hundred miles an hour. She stood on the glistening white sand of our private landing field on the eastern Florida coast. Below us the green Atlantic was running in white foam on the rocks.

In the year that Charlie King and I had been out of the Institute of Technology, we had built the nucleus of a commercial airplane business. We had designed and built here in our own shops several very successful seaplanes and amphibians. Charlie’s brilliant mathematical mind was of the greatest aid, except when he was too far lost in his abstruse speculations to descend to things commercial. Mathematics is painful enough to me when it is used in calculating the camber of an airplane wing. And pure mathematics, such as the theories of relativity and equivalence, I simply abhor.

I was amazed. Virginia Randall was a girl trim and beautiful as our shining Golden Gull. I had thought them devotedly in love, and had been looking forward to the wedding.

“But it isn’t two weeks, since Virginia was out here! You took her up in our Western Gull IV!”

Nervously Charlie lit his pipe, drew quickly on it. His face, lean and drawn beneath the flying goggles pushed up on his forehead, sought mine anxiously.

“I know. I drove her back to the station. That was when--when we quarreled.”

“But why? About Einstein? That’s silly.”

“She wanted me to give it up here, and go in with her father in his Wall Street brokerage business. The old gent is willing to take me, and make a business man of me.”

“Why, I couldn’t run the business without you, Charlie!”

“We talked about that, Hammond. I don’t really do much of the work. Just play around with the mathematics, and leave the models and blueprints to you.”

“Oh, Charlie, that’s not quite--”

“It’s the truth, right enough,” he said, bitterly. “You design aircraft, and I play with Einstein. And as you say, a fellow can’t eat equations.”

“I’d hate to see you go.”

“And I’d hate to give up you, and our business, and the math. Really no need of it. My tastes are simple enough. And old ‘Iron-clad’ Randall has made all one family needs. Virginia’s not exactly a pauper, herself. Two or three millions, I think.”

“And where did Virginia go?”

“She took the Valhalla yesterday at San Francisco. Going to join her father at Panama. He cruises about the world in his steam yacht, you know, and runs Wall Street by radio. I was to telegraph her if I’d changed my mind. I decided to stick to you, Hammond. I telegraphed a corsage of orchids, and sent her the message, ‘Einstein forever!’”

“If I know Virginia, those were not very politic words.”

“Well, a man--”

His words were cut short by a very unusual incident.

A thin, high scream came suddenly from above our neat stuccoed hangars at the edge of the white field. I looked up quickly, to catch a glimpse of a bright object hurtling through the air above our heads. The bellowing scream ended abruptly in a thunderous crash. I felt a tremor of the ground underfoot.

“What--” I ejaculated.

“Look!” cried Charlie.

He pointed. I looked over the gleaming metal wing of the _Golden Gull_, to see a huge cloud of white sand rising like a fountain at the farther side of the level field. Deliberately the column of debris rose, spread, rained down, leaving a gaping crater in the earth.

“Something fell?”

“It sounded like a shell from a big gun, except that it didn’t explode. Let’s get over and see!”

We ran to where the thing had struck, three hundred yards across the field. We found a great funnel-shaped pit torn in the naked earth. It was a dozen yards across, fifteen feet deep, and surrounded with a powdery ring of white sand and pulverized rock.

“Something like a shell-hole,” I observed.

“I’ve got it!” Charlie cried. “It was a meteor!”

“A meteor? So big?”

“Yes. Lucky for us it was no bigger. If it had been like the one that fell in Siberia a few years ago, or the one that made the Winslow crater in Arizona--we wouldn’t have been talking about it. Probably we have a chunk of nickel-iron alloy here.”

“I’ll get some of the men out here with digging tools, and we’ll see what we can find.”

Our mechanics were already hurrying across the field. I shouted at them to bring picks and shovels. In a few minutes five of us were at work throwing sand and shattered rock out of the pit.

Suddenly I noticed a curious thing. A pale bluish mist hung in the bottom of the pit. It was easily transparent, no denser than tobacco smoke. Passing my spade through it did not seem to disturb it in the least.

I rubbed my eyes doubtfully, said to Charlie, “Do you see a sort of blue haze in the pit?”

He peered. “No. No ... Yes. Yes, I do! Funny thing. Kind of a blue fog. And the tools cut right through it without moving it! Queer! Must have something to do with the meteor!” He was very excited.

We dug more eagerly. An hour later we had opened the hole to a depth of twenty feet. Our shovels were clanging on the gray iron of the rock from space. The mist had grown thicker as the excavation deepened; we looked at the stone through a screen of motionless blue fog.

We had found the meteor. There were several queer things about it. The first man who touched it--a big Swede mechanic named Olson--was knocked cold as if by a nasty jolt of electricity. It took half an hour to bring him to consciousness.

As fast as the rugged iron side of the meteorite was uncovered, a white crust of frost formed over it.

“It was as cold as outer space, nearly at the absolute zero,” Charlie explained. “And it was heated only superficially during its quick passage through the air. But how it comes to be charged with electricity--I can’t say.”

He hurried up to his laboratory behind the hangars, where he had equipment ranging from an astronomical telescope to a delicate seismograph. He brought back as much electrical equipment as he could carry. He had me touch an insulated wire to the frost-covered stone from space, while he put the other end to one post of a galvanometer.

I think he got a current that wrecked the instrument. At any rate, he grew very much excited.

“Something queer about that stone!” he cried. “This is the chance of a lifetime! I don’t know that a meteor has ever been scientifically examined so soon after falling.”

He hurried us all across to the laboratory. We came back with a truck load of coils and tubes and batteries and potentiometers and other assorted equipment. He had men with heavy rubber gloves lift the frost-covered stone to a packing box on a bench. The thing was irregular in shape, about a foot long; it must have weighed two hundred pounds. He sent a man racing on a motorcycle to the drug store to get dry ice (solidified carbon dioxide) to keep the iron stone at its low temperature.

In a few hours he had a complete laboratory set up around the meteorite. He worked feverishly in the hot sunshine, reading the various instruments he had set up, and arranging more. He contrived to keep the stone cold by packing it in a box of dry ice.

The mechanics stopped for dinner, and I tried to get him to take time to eat.

“No, Hammond,” he said. “This is something big! We were talking about Einstein. This rock seems energized with a new kind of force: all meteors are probably the same way, when they first plunge out of space. I think this will be to relativity what the falling apple is to gravity. This is a big thing.”

He looked up at me, brown eyes flashing.

“This is my chance to make a name, Hammond. If I do something big enough--Virginia might reconsider her opinion.”

Charlie worked steadily through the long hot afternoon. I spent most of the time helping him, or gazing in fascination at the curious haze of luminous blue mist that clung like a sphere of azure fog about the meteoric stone. I did not completely understand what he did; the reader who wants the details may consult the monograph he is preparing for the scientific press.

He had the men string up a line from our direct current generator in the shops, to supply power for his electrical instruments. He mounted a powerful electromagnet just below the meteorite, and set up an X-ray tube to bombard it with rays.

Night came, and the fire of the white sun faded from the sky. In the darkness, the curious haze about the stone became luminescent, distinct, a dim, motionless sphere of blue light. I fancied that I saw grotesque shapes flashing through it. A ball of blue fire, shimmering and ghost-like, shrouded the instruments.

Charlie’s induction coil buzzed wickedly, with purple fire playing about the terminals. The X-ray tube flickered with a greenish glow. He manipulated the rheostat that controlled the current through the electromagnet, and continued to read his instruments.

“Look at that!” he cried.

The bluish haze about the stone grew brighter; it became a ball of sapphire flame, five feet thick, bright and motionless. A great sphere of shimmering azure fire! Wisps of pale, sparkling bluish mist ringed it. The stone in its box, the X-ray bulb and other apparatus were hidden. The end of the table stuck oddly from the ball of light.

I heard Charlie move a switch. The hum of the coils changed a note.

The ball of blue fire vanished abruptly. It became a hole, a window in space!

Through it, we saw another world!

The darkness of the night hung about us. Where the ball had been was a circle of misty blue flame, five feet across. Through that circle I could see a vast expanse of blue ocean, running in high, white-capped rollers, beneath a sky overcast with low gray clouds.

It was no flat picture like a movie screen. The scene had vast depth; I knew that we were really looking over an infinite expanse of stormy ocean. It was all perfectly clear, distinct, real!

Astounded, I turned to find Charlie standing back and looking into the ring of blue fire, with a curious mixture of surprise and delighted satisfaction.

“What--what--” I gasped.

“It’s amazing! Wonderful! More than I had dared hope for! The complete vindication of my theory! If Virginia cares for scientific reputation--”

“But what is it?”

“It’s hard to explain without mathematical language. You might say that we are looking through a hole in space. The new force in the meteorite, amplified by the X-rays and the magnetic field, is causing a distortion of space-time coordinates. You know that a gravitational field bends light; the light of a star is deflected in passing the sun. The field of this meteorite bends light through space-time, through the four-dimensional continuum. That scrap of ocean we can see may be on the other side of the earth.”

I walked around the circle of luminous smoke with the marvelous picture in the center. It seemed that the window swung with me. I surveyed the whole angry surface of that slate-gray, storm-beaten sea, to the misty horizon. Nowhere was it broken by land or ship.

Charlie fell to adjusting his rheostat and switches.

It seemed that the gray ocean moved swiftly beyond the window. Vast stretches of it raced below our eyes. Faint black stains of steamer smoke appeared against the blue-gray horizon and swept past. Then land appeared--a long, green-gray line. We had a flash of a long coast that unreeled in endless panorama before us. It was such a view as one might get from a swift airplane--a plane flying thousands of miles per hour.

The Golden Gate flashed before us, with the familiar skyline of San Francisco rising on the hills behind it.

“San Francisco!” Charlie cried. “This is the Pacific we’ve been seeing. Let’s find the Valhalla. We might be able to see Virginia!”

The coast-line vanished as he manipulated his instruments. Staring into the circle of shining blue mist, I saw the endless ocean racing below us again. We picked up a pleasure yacht, running under bare poles.

“I didn’t know there was such a storm on,” Charlie murmured.

Other vessels swam past below us, laboring against heavy seas.

Then we looked upon an ocean whipped into mighty white-crowned waves. Rain beat down in sheets from low dense clouds; vivid violet lightnings flashed before us. It seemed very strange to see such lightning and hear not the faintest whisper of thunder--but no sound came from anything we saw through the blue-rimmed window in space.

“I hope the Valhalla isn’t in weather like this!” cried Charlie.

In a few minutes a dark form loomed through the wind-riven mist. Swiftly it swam nearer; became a black ship.

“Only a tramp,” Charlie said, breathing a sigh of relief.

It was a dingy tramp steamer, her superstructure wrecked. Her fires seemed dead. She lay across the wind, rolling sluggishly, threatening to sink with every monstrous wave. We saw no living person aboard her; she seemed a sinking derelict. We made out the name Roma on her side.

Charlie moved his dials again.

In a few minutes the slender prow of another great steamer came through the sheets of rain. It was evidently a passenger vessel. She seemed limping along, half wrecked, with mighty waves breaking over her rail.

Charlie grew white with alarm. “The Valhalla!” he gasped. “And she’s headed straight for that wreck!”

In a moment, as he brought the liner closer below our blue-rimmed window, I, too, made out the name. The wet, glistening decks were almost deserted. Here and there a man struggled futilely against the force of the storm.

In a few minutes the drifting wreck of the Roma came into our view, dead ahead of the limping liner. Through the mist and falling rain, the derelict could not have been in sight of the lookout of the passenger vessel until she was almost upon it.

We saw the white burst of steam as the siren was blown. We watched the desperate effort of the liner to check her way, to come about. But it was too much for the already crippled ship. Charlie cried out as a mighty wave drove the Valhalla down upon the sluggishly drifting wreck.

All the mad scene that ensued was strangely silent. We heard no crash when the collision occurred; heard no screams or shouts while the mob of desperate, white-faced passengers were fighting their way to the deck. The vain struggle to launch the boats was like a silent movie.

One boat was splintered while being lowered. Another, already filled with passengers, was lifted by a great ware and crushed against the side of the ship. Only shivered wood and red foam were left. The ship listed so rapidly that the boats on the lee side were useless. It was impossible to launch the others in that terrible, lashing sea.

“Virginia can swim.” Charlie said hopefully. “You know she tried the Channel last year, and nearly made it, too.”

He stopped to watch that terrible scene in white-faced, anxious silence.

The tramp went down before the steamer, drawing fragments of wrecked boats after it. The liner was evidently sinking rapidly. We saw dozens of hopeless, panic-stricken passengers diving off the lee side, trying to swim off far enough to avoid the tremendous suction.

Then, with a curious deliberation, the bow of the Valhalla dipped under green water; her stern rose in the air until the ship stood almost perpendicular. She slipped quickly down, out of sight.

Only a few swimming humans, and the wrecks of a few boats, were left on the rough gray sea. Charlie fumbled nervously with his dials, trying to get the scene near enough so that we could see the identity of the struggling swimmers.

A long boat, which must have been swept below by the suction of the ship, came plunging above the surface, upside down. It drifted swiftly among the swimmers, who struggled to reach it. I saw one person, evidently a girl, grasp it and drag herself upon it. It swept on past the few others still struggling.

The wrecked boat with the girl upon it seemed coming swiftly toward our blue-rimmed window. In a few minutes I saw something familiar about her.

“It’s Virginia!” Charlie cried. “God! We’ve got to save her, somehow!”

The long rollers drove the over-turned boat swiftly along. Virginia Randall clung desperately to it, deluged in foam, whipped with flying spray, the wild wind tearing at her.

About us, the clear still night was deepening. The air was warm and still; the hot stars shone steadily. Quiet lighted houses were in sight above the beach. It was very strange to look through the fire-rimmed circle, to see a girl struggling for life, clinging to a wrecked boat in a stormy sea.

Charlie watched in an apathy of grief and horror, trembling and speechless doing nothing except move the controls to keep the floating girl in our sight.

Hours went by as we watched. Then Charlie cried out in sudden hope. “There’s a chance! I might do it! I might be able to save her!”

“Might do what?”

“We are able to see what we do because the field of the meteor bends light through the four-dimensional continuum. The world line of a ray of light is a geodesic in the continuum. The field I have built distorts the continuum, so we see rays that originated at a distant point. Is that clear?”

“Clear as mud!”

“Well, anyhow, if the field were strong enough, we could bring physical objects through space-time, instead of mere visual images. We could pick Virginia up and bring her right here to the crater! I’m sure of it!”

“You mean you could move a girl through some four or five thousand miles of space!”

“You don’t understand. She wouldn’t come through space at all, but through space-time, through the continuum, which is a very different thing. She is four thousand miles away in our three-dimensional space, but in space-time, as you see, she is only a few yards away. She is only a few yards from us in the fourth dimension. If I can increase the field a little, she will be drawn right through!”

“You’re a wizard if you can do it!”

“I’ve got to do it! She’s a fine swimmer--that’s the only reason she’s still alive--but she’ll never live to reach the shore. Not in a sea like that!”

Charlie fell to work at once, mounting another electromagnet beside the one he had set up, and rigging up two more X-ray bulbs beside the packing box which held the meteor. The motion of the boat in the fire-rimmed window kept drawing it swiftly away from us, and Charlie showed me how to move the dial of his rheostat to keep the girl in view.

Before he had completed his arrangements, a patch of white foam came into view just ahead of the drifting boat. In a moment I made out a cruel black rock, with the angry sea breaking into fleecy spray upon it. The boat was almost upon it, driving straight for it. Charlie saw it, and cried out in horror.

The long black hull of the splintered boat, floating keel upward, was only a few yards away. A great white-capped breaker lifted it and hurled it forward, with the girl clinging to it. She drew herself up and stared in terror at the black rock, while another long surging roller picked up the boat and swept it forward again.

I stood, paralyzed in horror, while the shattered boat was driven full upon the great rock. I could imagine the crash of it, but it was all as still as a silent picture. The boat, riding high on a crest of white foam, smashed against the rock and was shivered to splinters. Virginia was hurled forward against the slick wet stone. Desperately she scrambled to reach the top of the boulder. Her hands slipped on the polished rock; the wild sea dragged at her. At last she got out of reach of the angry gray water, though spume still deluged her.

I breathed a sigh of relief, though her position was still far from enviable.

“Virginia! Virginia! Why did I let you go?” Charlie cried.

Desperately he fell to work again, mounting the magnet and tubes. Another hour went by, while I watched the shivering girl on the rock. Bobbed hair, wet and glistening, was plastered close against her head, and her clothing was torn half off. She looked utterly exhausted; it seemed to take all her ebbing energy to cling to the rock against the force of the wind and the waves that dashed against her. She looked cold, blue and trembling.

The water stood higher.

“The tide is rising!” Charlie exclaimed. “It will cover the rock pretty soon. If I don’t get her off in time--she’s lost!”

He finished twisting his wires together.

“I’ve got it all ready,” he said. “Now, I’ve got to find out exactly where she is, to know how to set it. Even then it’s fearfully uncertain. I hate to try it, but it’s the only chance.

“You can find out?”

“Yes. From the spectral shift and other factors. I’ll have to get some other apparatus.” He ran up to the laboratory, across the level field that lay black beneath the stars. He came back, panting, with spectrometer, terrestrial globe, and other articles.
