Four mooring bars dropped neatly into their sockets and the captain-pilot, after locking his controls in neutral, released his safety straps and leaped lightly from his padded bench to the floor. Scuttling across the floor and down a runway upon his four short, powerful, heavily scaled legs, he slipped smoothly into the water and flashed away, far below the surface. For Nevians are true amphibians. Their blood is cold; they use with equal comfort and efficiency gills and lungs for breathing; their scaly bodies are equally at home in the water or in the air; their broad, flat feet serve equally well for running about upon a solid surface or for driving their streamlined bodies through the water at a pace few fishes can equal.
Through the water the Nevian commander darted along, steering his course accurately by means of his short, vaned tail. Through an opening in a wall he sped and along a submarine hallway, emerging upon a broad ramp. He scurried up the incline and into an elevator which lifted him to the top of the hexagon, directly into the office of the Secretary of Commerce of all Nevia.
"Welcome, Captain Nerado!" The Secretary waved a tentacular arm and the visitor sprang lightly upon a softly cushioned bench, where he lay at ease, facing the official across his low, flat "desk." "We congratulate you upon the success of your final trial flight. We received all your reports, even while you were traveling at ten times the velocity of light. With the last difficulties overcome, you are now ready to start?"
"We are ready," the captain-scientist replied, soberly. "Mechanically, the ship is as nearly perfect as our finest minds can make her. She is stocked for two years. All the iron-bearing suns within reach have been plotted. Everything is ready except the iron. Of course the Council refused to allow us any of the national supply—how much were you able to purchase for us in the market?"
"Nearly ten pounds...."
"Ten pounds! Why, the securities we left with you could not have bought two pounds, even at the price then prevailing!"
"No, but you have friends. Many of us believe in you, and have dipped into our own resources. You and your fellow scientists of the expedition have each contributed his entire personal fortune; why should not some of the rest of us also contribute, as private citizens?"
"Wonderful—we thank you. Ten pounds!" The captain's great triangular eyes glowed with an intense violet light. "At least a year of cruising. But ... what if, after all, we should be wrong?"
"In that case you shall have consumed ten pounds of irreplaceable metal." The Secretary was unmoved. "That is the viewpoint of the Council and of almost everyone else. It is not the waste of treasure they object to; it is the fact that ten pounds of iron will be forever lost."
"A high price, truly," the Columbus of Nevia assented. "And after all, I may be wrong."
"You probably are wrong," his host made startling answer. "It is practically certain—it is almost a demonstrable mathematical fact—that no other sun within hundreds of thousands of light-years of our own has a planet. In all probability Nevia is the only planet in the entire Universe. We are very probably the only intelligent life in the Universe. There is only one chance in numberless millions that anywhere within the cruising range of your newly perfected space-ship there may be an iron-bearing planet upon which you can effect a landing. There is a larger chance, however, that you may be able to find a small, cold, iron-bearing cosmic body—small enough so that you can capture it. Although there are no mathematics by which to evaluate the probability of such an occurrence, it is upon that larger chance that some of us are staking a portion of our wealth. We expect no return whatever, but if you should by some miracle happen to succeed, what then? Deep seas being made shallow, civilization extending itself over the globe, science advancing by leaps and bounds, Nevia becoming populated as she should be peopled—that, my friend, is a chance well worth taking!"
The Secretary called in a group of guards, who escorted the small package of priceless metal to the space-ship. Before the massive door was sealed the friends bade each other farewell.
"... I will keep in touch with you on the ultra-wave," the Captain concluded. "After all, I do not blame the Council for refusing to allow the other ship to go out. Ten pounds of iron will be a fearful loss to the world. If we should find iron, however, see to it that she loses no time in following us."
"No fear of that! If you find iron she will set out at once, and all space will soon be full of vessels. Goodbye."
The last opening was sealed and Nerado shot the great vessel into the air. Up and up, out beyond the last tenuous trace of atmosphere, on and on through space it flew with ever-increasing velocity until Nevia's gigantic blue sun had been left so far behind that it became a splendid blue-white star. Then, projectors cut off to save the precious iron whose disintegration furnished them power, for week after week Captain Nerado and his venturesome crew of scientists drifted idly through the illimitable void.
There is no need to describe in detail Nerado's tremendous voyage. Suffice it to say that he found a G-type dwarf star possessing planets—not one planet only, but six ... seven ... eight ... yes, at least nine! And most of those worlds were themselves centers of attraction around which were circling one or more worldlets! Nerado thrilled with joy as he applied a full retarding force, and every creature aboard that great vessel had to peer into a plate or through a telescope before he could believe that planets other than Nevia did in reality exist!
Velocity checked to the merest crawl, as space-speeds go, and with electro-magnetic detector screens full out, the Nevian vessel crept toward our sun. Finally the detectors encountered an obstacle, a conductive substance which the patterns showed conclusively to be practically pure iron. Iron—an enormous mass of it—floating alone out in space! Without waiting to investigate the nature, appearance, or structure of the precious mass, Nerado ordered power into the converters and drove an enormous softening field of force upon the object—a force of such a nature that it would condense the metallic iron into an allotropic modification of much smaller bulk; a red, viscous, extremely dense and heavy liquid which could be stored conveniently in his tanks.
No sooner had the precious fluid been stored away than the detectors again broke into an uproar. In one direction was an enormous mass of iron, scarcely detectable; in another a great number of smaller masses; in a third an isolated mass, comparatively small in size. Space seemed to be full of iron, and Nerado drove his most powerful beam toward distant Nevia and sent an exultant message.
"We have found iron—easily obtained and in unthinkable quantity—not in fractions of milligrams, but in millions upon unmeasured millions of tons! Send our sister ship here at once!"
"Nerado!" The captain was called to one of the observation plates as soon as he had opened his key. "I have been investigating the mass of iron now nearest us, the small one. It is an artificial structure, a small space-boat, and there are three creatures in it—monstrosities certainly, but they must possess some intelligence or they could not be navigating space."
"What? Impossible!" exclaimed the chief explorer. "Probably, then, the other was—but no matter, we had to have the iron. Bring the boat in without converting it, so that we may study at our leisure both the beings and their mechanisms," and Nerado swung his own visiray beam into the emergency boat, seeing there the armored figures of Clio Marsden and the two Triplanetary officers.
"They are indeed intelligent," Nerado commented, as he detected and silenced Costigan's ultra-beam communicator. "Not, however, as intelligent as I had supposed," he went on, after studying the peculiar creatures and their tiny space-ship more in detail. "They have immense stores of iron, yet use it for nothing other than building material. They make little and inefficient use of atomic energy. They apparently have a rudimentary knowledge of ultra-waves, but do not use them intelligently—they cannot neutralize even these ordinary forces we are now employing. They are of course more intelligent than the lower ganoids, or even than some of the higher fishes, but by no stretch
