Parker set his fingers into the arms of his chair as Von Stein rose and walked to the copper bowl. He stood directly under it, and put on goggles with shields fitting close to his feet. At the pressure of his foot a tablelike affair rose from the floor in front of him. This, like the desk, was equipped with numerous dials, buttons and levers. Von Stein manipulated them. The great cap of copper descended until his head was enveloped by the mist of platinum wires. A faint humming grew in the room. A tiny bell tinkled.
"The connection is made," murmured Von Stein. He lifted a hand for silence: then his fingers leaped among the gadgets on the table. After that came a brief period, measured by seconds, of immobility. Then the table sank from view, the copper bowl lifted, and Dr. von Stein went back to his chair.
"She will be here shortly," he said. "If that does not change your mind…"
He shrugged. Parker knew what that shrug meant. He searched his mind for a plan and found none. Better die fighting than yield, or risk the vengeance of Friedrich von Stein. If he could get the doctor away from the desk where he controlled the blue-white flame there might be a chance to do something. Von Stein was by far the larger man, but Parker had been an athlete all his life. If…
"That mass of copper and platinum," he said, tentatively, "will make you master of the world!"
"My brain, my intelligence, has made me master of the world!" corrected Von Stein, proudly. He was touched in the right spot now. "You have not seen all!"

He sprang up and went to one of the tables. From his pocket he took a piece of paper and crumpled it into a ball while, with the other hand, he made some electrical connections to a plate of metal set into the surface of the table. Next he placed the wad of paper on the plate. Then, standing at arm's length from the apparatus, he pressed a button. Instantly the paper disappeared behind a screen of the colors of the spectrum, from red to violet. The banded colors were there for a minute fraction of a second. Then there was nothing where the paper had been on the plate. Von Stein smiled as he stepped away from the table.
"The electron is formed by the crossing of two lines of force," he said, "and the interaction of positive and negative polarity. The electron is a stress in the ether, nothing more, but it is the stuff of which all matter is made. Thought is vibration in one dimension; matter in two. You have just seen me untie the knot, dissociate the electrons, or what you will. In plain language I have caused matter to vanish utterly. That paper is not burned up. It no longer exists in any form. The earth upon which we stand, Parker, can be dissolved like mist before the sun!"
Appalled as he was at this man who boasted and made good his terrible boasts Allen Parker had not forgotten the purpose that was in him. Now was his chance, while Von Stein stood smiling triumphantly between table and desk.
Parker shot from his chair with the speed of utter desperation. He feinted, and drove a vicious uppercut to the jaw of Dr. Friedrich von Stein. The doctor reeled but he did not go down. His fists swung. Parker found him no boxer, and beat a tattoo upon his middle. Von Stein began to slump.
Then two thick muscled arms closed around the artist from behind and he was lifted clear of the floor. He kicked, and tried to turn, but it was useless. The doctor recovered himself. His eyes blazed fury.
"Put him in the chair, Heinrich!" he roared. "For this I will show you what I can do, Herr Parker!"

At that instant little Hans, who had been yelping on the edge of the battle, dashed in. He leaped for the throat of Von Stein. The doctor kicked him brutally.
The shriek of agony from Hans loosened the arms of Heinrich. Parker got his footing again. He saw the clumsy serving man spring forward and gather his dog up to his breast. Again Parker rushed for his enemy.
It was clear now that Von Stein was cut off from the controls he wanted, and without Heinrich he could not master Parker in a fight. For an instant he stood baffled. Then he retreated the length of the room, taking what blows he could not beat off. He staggered upon a plate of metal set into the floor, righted himself, and failed in an attempt to catch hold of Parker. Suddenly he bowed in the direction of the distant doorway.
Allen half turned. Betty was coming down the room, staring and breathless.
"Leben sie wohl!" cried Von Stein. "Farewell, Madame! I should like to take you with me!"
A great flash of the colors of the spectrum sent Parker reeling back. Dr. Friedrich von Stein had gone the way of the crumpled ball of paper.
There was a long moment of silence. Then Allen Parker found his wife in his arms, clinging to him.
"'Are not two prayers a perfect strength?'" she murmured, sobbing against his heart.
A HUNDRED MILES UNDERGROUND
Scientists bidding their families good-by in the morning to drop fifty or a hundred miles underground in high speed elevators, there to undertake researches not possible nearer to the earth's surface, may be realities of the next decade or two if some wealthy individual or institution accepts the recommendation of Dr. Harlow Shapley, distinguished astronomer of Harvard, in a talk recently before the American Geographical Society.
The earth's interior, Dr. Shapley said, is the "third dimension" of geography. Exploration of the planet's surface soon must cease from lack of places to explore. Even the upper air is coming to be reasonably well known scientifically, thanks to instruments sent up with balloons and to the radio and other investigators who have been uncovering secrets of upper-air electricity. But the interior of the earth is still one of the great mysteries. It is a paradox of astronomy that much more is known about the center of the sun or a star like Sirius than about the center of the earth.
Deep shafts of bore holes into the earth have been suggested often as sources of heat for human use. It is doubtful, however, whether such heat supplies could be obtained. For one thing, the supposed internal heat of the earth is still nothing but a guess. It may be that the relatively slight increases of heat found as one goes deeper in existing mines are due to radioactivity in the rocks instead of to outward seepage from the internal fires. Another difficulty about utilizing earth heat is that heat moves so slowly through substances like rock, as any housewife can prove by trying to fry an egg on a brick placed over a gas flame. As soon as the rock heat immediately at the bottom of a bore hole had been exhausted heat supply would stop until more could diffuse in from the sides.
Dr. Shapley's suggestion, in any event, is not to search for heat but for facts. Even in existing, relatively shallow mines, he believes, scientific laboratories at different depths under the surface might yield valuable data not now obtainable. Most scientific men will agree. Revolutionary as the idea may seem to those familiar only with the standardized laboratories of physics or chemistry, there are sound reasons why a half-dozen or so of the sciences should do precisely what Dr. Shapley suggests.
At least one underground laboratory has already been installed, for Prof. E. B. Babcock of the University of California has such a workroom in the Twin Peaks Tunnel, underneath the mountain that rises above the city of San Francisco. Natural radioactivity in the rocks thereabouts is greater than normal and Prof. Babcock finds that this apparently increases new species among fruit flies.
To dig out laboratory rooms a mile or so down in existing deep mines probably would cost far less than many enterprises already financed by philanthropists. Even to deepen these shafts for several miles would be much less difficult than most people imagine.
Increasing heat, if it is found that heat does increase, would not be difficult to overcome had the engineers sufficient money. Ventilation and transportation to and from the surface, while too costly for the business enterprise of winning metals from very deep mines, probably would present no serious difficulty were facts the chief object instead of profit. The only question to be decided before intending benefactors of science are urged to consider some such project is whether or not the facts likely to be won promise enough value to mankind.
An excellent case can be made out for answering yes. Dr. Shapley mentioned four chief lines of investigation suitable for such deep-mine laboratories: studies of gravity and of the variable length of the day, researches on the various kinds of earthquake waves, experiments on ether drift and tests of the biological effects of cosmic rays and of the rays from radium.
Astronomical theories indicate that the day ought to be growing slightly longer as the earth's rotation decreases a trifle from century to century because of friction from the tides. The actual length of the days seems, however, sometimes to be decreasing a tiny fraction of a second from year to year, as theory says that it should; sometimes to be increasing in a way for which no present theory provides. Observations underneath the earth, with a portion of the planet's crust and gravity overhead, might yield important clues to the cause of this mysterious wrong time kept by the terrestrial clock.
The Gray Plague
By L. A. Eshbach
CHAPTER I
Five months before the beginning of that period of madness, that time of chaos and death that became known as the Gray Plague, the first of the strange meteors fell to Earth. It landed a few miles west of El Paso, Texas, on the morning of March 11th.
Maimed and captive, in the depths of an interplanetary meteor-craft, lay the only possible savior of plague-ridden Earth.
In a few hours a great throng of people gathered around the dully smoldering mass of fire-pitted rock, the upper half of which protruded from the Earth where it had buried itself, like a huge, roughly outlined hemisphere. And then, when the crowd had assumed its greatest proportions, the meteor, with a mighty, Earth-shaking roar, exploded.
A vast flood of radiance, more brilliant than the light of the sun, lit up the sky for miles around. One moment, a throng of curious people, a number of scientists, newspaper men – a crashing explosion – and then a great, yawning pit sending forth a blinding radiance! Destruction and death where life had been.
The brilliant light streamed from the pit for about ten minutes; then like a snuffed-out candle flame, it vanished.
The second of the strange meteors landed on the evening of March 13th, in the city of Peking, China. It demolished several buildings, and buried itself beneath the ruins. The Chinese, unaware of the tragedy at El Paso, gathered in the vicinity, and when the meteor exploded at about ten o'clock that night, were instantly destroyed. As in Texas, the great pit emitted a cloud of dazzling light for about ten minutes, throwing a brilliant glow over the city and its surroundings; then was extinguished.
The people of the world awoke to the fact that events worthy of more than passing interest were occurring. The press of every nation begin giving the strange meteors more and more publicity. Statements of different pseudo-scientists were published in explanation of the meteor's origin, statements that aroused world wide conjecture.
_______________________
Approximately twenty-four hours after the falling of the second missile, the third one fell, landing near Madrid, Spain. The Spaniards, having received news of the El Paso and Peking tragedies, avoided the ugly mass of rock as though it were a dreaded pestilence. In every way its action was similar to that of its two predecessors.
The interest of the world was doubled now. The unusual similarity of the action of the meteors, and the regularity of their landings, seemed indicative of a definite, hostile purpose behind it all. A menace from the unknown – a peril from the skies!
Scientists began giving serious consideration to the unusual phenomenon, pottering around in the pits, wearing airs of puzzlement. But their investigations were of no avail, for nothing of any great significance came to light through their efforts.
At about that time, an announcement was made that created a furor. Astronomers in different parts of the United States reported that they had observed a bright flare of light leaping up from the darkened portion of the planet Venus. The astronomers had no definite idea of anything of importance in back of what they had seen; but not so the masses. The flare, they said, was caused by the release of another meteor!
From Venus! Missiles, hurled by Venerians, menacing the Earth! The silver planet became the subject of universal discussion; innumerable fantastic articles about it appeared in magazine sections of Sunday newspapers. And the astronomers of Earth turned their telescopes toward Venus with an interest they had never felt before.
