The Space Opera Megapack: 20 Modern and Classic Science Fiction Tales

  “Yes—we can signal easily,” Arcot answered; he struggled with the newly acquired language. “I do not know the word in your tongue—it may be that you do not have it—radio we call it—it is akin to light, but of vastly longer wavelength. Produced electrically, it can be directed like light and sent in a beam by means of a reflection. It can penetrate all substances except metals, and can leak around them, if it be not directional. With it I can talk readily with the men of Earth, and this very night I will.”

  Arcot paused, frowning thoughtfully, then continued, “I know there’s definite need for haste, but we can’t do anything until Morey has received the knowledge you’ve given me. While we’re waiting here, I might just as well learn all I can about your planet. The more I know, the more intelligently I’ll be able to plan for our defense.”

  In the conversation which followed, Arcot gained a general knowledge of the physical makeup of Venus. He learned that iron was an exceedingly rare element on the planet, while platinum was relatively plentiful. Gold, though readily available, was considered a nuisance, since it was of no practical value due to its softness, excessive weight and its affinity for many catalysts. Most of the other metallic elements were present in quantities approximating those of Earth, except for an element called “morlus”. When Tonlos mentioned this, Arcot said:

  “Morlus—I have the word in your language—but I do not know the element. What is it?”

  “Why—here is some!”

  Tonlos handed Arcot a small block of metal that had been used as a weight on a table in one corner of the room. It seemed fairly dense, about as heavy as iron, but it had a remarkably bluish tint. Obviously, it was the element that composed the wings of the airplane they had seen that afternoon. Arcot examined it carefully, handicapped somewhat by its heat. He picked up a small copper rod and tried to scratch it but there was no noticeable effect.

  “You cannot scratch it with copper,” said Tonlos. “It is the second hardest metal we know—it is not as hard as chromium, but far less brittle. It is malleable, ductile, very very strong, very tough, especially when alloyed with iron, but those alloys are used only in very particular work because of iron’s rarity.”

  Indicating the bluish block, Arcot said, “I’d like to identify this element. May I take it back to the ship and test it?”

  “You may, by all means. You will have considerable difficulty getting it into solution, however. It is attacked only by boiling selenic acid which, as you must know, dissolves platinum readily. The usual test for the element is to so dissolve it, oxidize it to an acid, then test with radium selenate, when a brilliant greenish blue salt is—”

  “Test with radium selenate!” Arcot exclaimed. “Why, we have no radium salts whatever on Earth that we could use for that purpose. Radium is exceedingly rare!”

  “Radium is by no means plentiful here,” Tonlos replied,“but we seldom have to test for morlus, and we have plenty of radium salts for that purpose. We have never found any other use for radium—it is so active that it combines with water just as sodium does; it is very soft—a useless metal, and dangerous to handle. Our chemists have never been able to understand it—it is always in some kind of reaction no matter what they do, and still it gives off that very light gas, helium, and a heavy gas, niton, and an unaccountable amount of heat.”

  “Your world is vastly different from ours,” Arcot commented. He told Tonlos of the different metals of Earth, the non-metals, and their occurrence. But try as he would, he could not place the metal Tonlos had given him.

  Morey’s arrival interrupted their discussion. He looked very tired, and very serious. His head ached from his unwonted mental strain, just as Arcot’s had. Briefly Arcot told him what he had learned, concluding with a question as to why Morey thought the two planets, both members of the same solar family, should be so different.

  “I have an idea,” said Morey slowly, “and it doesn’t seem too wacky. As you know, by means of solar photography, astronomers have mapped the sun, charting the location of the different elements. We’ve seen hydrogen, oxygen, silicon and others, and as the sun aged, the elements must have been mixed up more and more thoroughly. Yet we have seen the vast areas of single elements. Some of those areas are so vast that they could easily be the source of an entire world! I wonder if it is not possible that Earth was thrown off from some deposit rich in iron, aluminum and calcium, and poor in gold, radium and those other metals—and particularly poor in one element. We have located in the sun the spectrum of an element we have named coronium—and I think you have a specimen of coronium in your hand there! I’d say Venus came from a coronium-rich region!”

  The discussion ended there, for already the light outside had deepened to a murky twilight. The Terrestrians were led quickly down to the elevator, which dropped them rapidly to the ground. There was still a large crowd about the Solarite, but the way was quickly cleared for them. As the men passed through the crowd, a peculiar sensation struck them very forcibly. It seemed that everyone in the crowd was wishing them the greatest success—the best of good things in every wish.

  “The ultimate in applause! Morey, I’ll swear we just received a silent cheer!” exclaimed Arcot, as they stood inside the airlock of the ship once more. It seemed home to them now! In a moment they had taken off the uncomfortable ventilating suits and stepped once more into the room where Wade and Fuller awaited them.

  “Say—what were you fellows doing?” Wade demanded.“We were actually getting ready to do some inquiring about your health!”

  “I know we were gone a long time—but when you hear the reason you’ll agree it was worth it. See if you can raise Earth on the radio, Morey, will you, while I tell these fellows what happened? If you succeed, tell them to call in Dad and your father, and to have a couple of tape recorders on the job. We’ll want a record of what I have to send. Say that we’ll call back in an hour.” Then, while Morey was busy down in the power room sending the signals out across the forty million miles of space that separated them from their home planet, Arcot told Wade and Fuller what they had learned.

  Morey finally succeeded in getting his message through, and returned to say that they would be waiting in one hour. He had had to wait eight minutes after sending his message to get any answer, however, due to time required for radio waves to make the two-way trip.

  “Fuller,” Arcot said, “as chef, suppose you see what you can concoct while Wade and I start on this piece of coronium and see what there is to learn.”

  At the supper table Wade and Arcot reported to the others the curious constants they had discovered for coronium. It was not attacked by any acid except boiling selenic acid, since it formed a tremendous number of insoluble salts. Even the nitrate violated the long-held rule that “all nitrates are soluble”—it wouldn’t dissolve. Yet it was chemically more active than gold.

  But its physical constants were the most surprising. It melted at 2800° centigrade, a very high melting point indeed. Very few metals are solid at that temperature. But the tensile strength test made with a standard bar they finally turned out by means of a carbaloy tool, gave a reading of more than one million, three hundred thousand pounds per square inch! It was far stronger than iron—stronger than tungsten, the strongest metal heretofore known. It was twice as strong as the Earth’s strongest metal!

  Fuller whistled in awe. “No wonder they can make a plane like that when they have such a metal to work with.” The designing engineer had visions of a machine after his own heart—one in which half the weight was not employed in holding it together!

  It was a little later that they got communication through to Earth, and the men went to the power room. The television screen was struggling to form a clear image despite the handicap of forty million miles of space. In a moment it had cleared, though, and they saw the face of Dr. Arcot. He showed plainly that he was worried about the startling news that had reached him already, sketchy though it was. After brief though warm greetings, his son rapidly outl
ined to him the full extent of their discoveries, and the force that Earth would have to meet.

  “Dad, these Kaxorians have planes capable of far more than a thousand miles an hour in the air. For some reason the apparatus they use to propel them in space is inoperative in air, but their propellers will drive them forward faster than any plane Earth ever saw. You must start at once on a fleet of these molecular motion planes—and a lot of the gas Wade developed—you know how to make it—the animation suspending gas. They don’t have it—and I believe it will be useful. I’ll try to develop some new weapons here. If either of us makes any progress along new lines—we’ll report to the other. I must stop now—a Lanorian delegation is coming.” After a few words of farewell, Arcot severed connections with the Earth and arose to await the arrival of the visitors.

  Since the return of the Terrestrians to the Solarite, a great crowd of Venerians had gathered around it, awaiting a glimpse of the men, for the news had spread that this ship had come from Earth. Now, the crowd had divided, and a group of men was approaching, clothed in great heavy coats that seemed warm enough to wear in Terrestrial arctic regions!

  “Why—Arcot—what’s the idea of the winter regalia?” asked Fuller in surprise.

  “Think a moment—they are going to visit a place whose temperature is seventy degrees colder than their room temperature. In the bargain, Venus never has any seasonal change of temperature, and a heavy bank of clouds that eternally cover the planet keeps the temperature as constant as a thermocouple arrangement could. The slight change from day to night is only appreciable by the nightly rains—see—the crowd is beginning to break up now. It’s night already, and there is a heavy dew settling. Soon it will be rain, and the great amount of moisture in the air will supply enough heat, in condensing, to prevent a temperature drop of more than two or three degrees. These men are not used to changes in temperature as we are and hence they must protect themselves far more fully.”

  Three figures now entered the airlock of the Solarite, and muffled in heavy garments as they were, large under any conditions, they had to come through one at a time.

  Much that Arcot showed them was totally new to them. Much he could not explain to them at all, for their physics had not yet reached that stage.

  But there was one thing he could show them, and he did. There were no samples of the liquids he wanted, but their chemistry was developed to a point that permitted the communication of the necessary data and Arcot told them the formula of Wade’s gas. Its ability to penetrate any material at ordinary temperatures, combined with its anesthetic properties, gave it obvious advantages as a weapon for rendering the opposing forces defenseless.

  Since it was able to penetrate all substances, there was no means of storing it. Hence it was made in the form of two liquids which reacted spontaneously and produced the gas, which was then projected to the spot where needed.

  Arcot asked now that the Venerian chemists make him a supply of these two liquids; and they promptly agreed. He felt he would have a fighting chance in combatting the enemy if he could but capture one of their flying forts. It seemed a strange task! Capturing so huge a machine with only the tiny Solarite—but Arcot felt there was a good possibility of his doing it if he but had a supply of that gas.

  There was one difficulty—one step in the synthesis required a considerable quantity of chlorine. Since chlorine was rare on Venus, the men were forced to sacrifice most of their salt supply; but this chlorine so generated could be used over and over again.

  It was quite late when the Venerians left, to go again into the scalding hot rain, rain that seemed to them to be a cold drizzle. After they had gone, the Terrestrians turned in for the night, leaving a telephone connection with the armed guard outside.

  The dull light of the Venerian day was filtering in through the windows the next morning when the Terrestrians awoke. It was eight o’clock, New York time, but Sonor was working on a twenty-three hour day. It happened that Sonor and New York had been in opposition at midnight two nights ago, which meant that it was now ten o’clock Sonorian time. The result was that Arcot left the car to speak to the officer in charge of the guard about the ship.

  “We need some pure water—water free of copper salts. I think it would be best if you can get me some water that has been distilled. That is, for drinking. Also we need about two tons of water of any kind—the ship’s tanks need recharging. I’d like about a ton of the drinking water.” Arcot had to translate the Terrestrian measures into the corresponding Venerian terms, of course, but still the officer seemed puzzled. Such a large amount of water would create a real problem in transportation. After apparently conferring by telepathic means with his superiors, the officer asked if the Solarite could be moved to some more accessible place.

  Arcot agreed to have it moved to a spot just outside the city, where the water could be procured directly from a stream. The drinking water would be ready when he returned to the city.

  The Solarite was moved to the bank of the little river and the electrolysis apparatus was set up beside it. During the previous day, and ever since they had landed on Venus, all their power had been coming from the storage cells, but now that the electrolysis apparatus was to establish such a heavy and constant drain, Arcot started the generator, to both charge the cells, and to do the work needed.

  Throughout the day there could be heard the steady hum of the generator, and the throb-throb-throb of the oxygen pump, as the gas was pumped into the huge tanks. The apparatus they were using produced the gas very rapidly, but it was near nightfall before the huge tanks had again been filled. Even then there was a bit more room for the atomic hydrogen that was simultaneously formed, although twice as much hydrogen as oxygen was produced. Its task completed, the Solarite rose again and sped toward the distant city.

  A soft red glow filled the sky now, for even through the miles of clouds the intense sun was able to force some direct rays, and all the city was lighted with that warm radiance. The floodlights had not yet been turned on, but the great buildings looming high in the ruddy light were wonderfully impressive, the effect being heightened by the planned construction, for there were no individual spires, only a single mass that grew from the ground to tower high in the air, like some man-made mountain.

  Back at the Capital the Solarite again settled into the broad avenue that had been cut off to traffic now, and allotted to it as its resting place. Tonlos met them shortly after they had settled into place, and with him were five men, each carrying two large bottles.

  “Ah-co,” as Tonlos pronounced the Terrestrian name, “we have not been able to make very much of the materials needed for your gas, but before we made any very great amount, we tried it out on an animal, whose blood structure is the same as ours, and found it had the same effect, but that in our case the iodide of potassium is not as effective in awakening the victim as is the sorlus. I do not know whether you have tried that on Terrestrial animals or not. Luckily sorlus is the most plentiful of the halogen groups; we have far more of it than of chlorine, bromine or iodine.”

  “Sorlus? I do not know of it—it must be one of the other elements that we do not have on Earth. What are its properties?”

  “It, too, is much like iodine, but heavier. It is a black solid melting at 570 degrees; it is a metallic looking element, will conduct electricity somewhat, oxidizes in air to form an acidic oxide, and forms strong oxygen acids. It is far less active than iodine, except toward oxygen. It is very slightly soluble in water. It does not react readily with hydrogen, and the acid where formed is not as strong as HI.”

  “I have seen so many new things here, I wonder if it may not be the element that precedes niton. Is it heavier than that?”

  “No,” replied Tonlos; “it is just lighter than that element you call niton. I think you have none of it.”

  “Then,” said Arcot, “it must be the next member of the halogen series, Morey. I’ll bet they have a number of those heavier elements.”

  The
gas was loaded aboard the Solarite that evening, and when Wade saw the quantity that they had said was “rather disappointingly small” he laughed heartily.

  “Small! They don’t know what that gas will do! There’s enough stuff there to gas this whole city. Why, with that, we can bring down any ship! But tell them to go on making it, for we can use it on the other ships.”

  Again that night they spoke with Earth, and Morey, Senior, told them that work was already under way on a hundred small ships. They were using all their own ships already, while the Government got ready to act on the idea of danger. It had been difficult to convince them that someone on Venus was getting ready to send a force to Earth to destroy them; but the weight of their scientific reputation had turned the trick. The ships now under construction would be ready in three weeks. They would be unable to go into space, but they would be very fast, and capable of carrying large tanks of the gas-producing chemicals.

  It was near midnight, Venerian time, when they turned in. The following day they planned to start for the Kaxorian construction camp. They had learned from Tonlos that there were but five of the giant planes completed now, but there were fifteen more under construction, to make up the fleet of twenty that was to attack Earth. These fifteen others would be ready in a week—or less. When they were ready, the Solarite would stand small chance. They must capture one of the giants and learn its secrets, and then, if possible, with the weapons and knowledge of two worlds, defeat them. A large order!

  Their opportunity came sooner than they had hoped for—or wanted. It was about three o’clock in the morning when the telephone warning hummed loudly through the ship. Arcot answered.

  Far to the east and south of them the line of scout planes that patrolled all the borders of Lanor had been broken. Instantaneously, it seemed, out of the dark, its lights obscured, the mighty Kaxorian craft had come, striking a tiny scout plane head on, destroying it utterly before the scout had a chance to turn from the path of the titanic ship. But even as the plane spun downward, the pilot had managed to release a magnesium flare, a blindingly brilliant light that floated down on a parachute, and in the blaze of the white light it gave off, the other scouts at a few miles distance had seen the mighty bulk of the Kaxorian plane. At once they had dropped to the ground and then, by telephone lines, had sent their report to far off Sonor.
