"All ordinary vibrations—that is, all molecular and material ones, such as light, heat, electricity, radio, and the like—were arbitrarily called waves of the first order; in order to distinguish them from waves of the second order, which are given off by particles of the second order, which you know as protons and electrons, in their combination to form atoms. Your scientist Millikan discovered these rays for you, and in your language they are known as Millikan, or Cosmic, rays.
"Some time later, when sub-electrons were identified the rays given off by their combination into electrons, or by the disruption of electrons, were called rays of the third order. These rays are most interesting and most useful; in fact, they do all our mechanical work. They as a class are called protelectricity, and bear the same relation to ordinary electricity that electricity does to torque—both are pure energy, and they are inter-convertible. Unlike electricity, however, it may be converted into many different forms by fields of force, in away comparable to that in which white light is resolved into colors by a prism—or rather, more like the way alternating current is changed to direct current by a motor-generator set, with attendant changes in properties. There is a complete spectrum of more than five hundred factors, each as different from the others as red is different from green.
"Continuing farther, particles of the fourth order give rays of the fourth order; those of the fifth, rays of the fifth order. Fourth-order rays have been investigated quite thoroughly, but only mathematically and theoretically, as they are of excessively short wave-length and are capable of being generated only by the breaking down of matter itself into the corresponding particles. However, it has been shown that they are quite similar to protelectricity in their general behavior. Thus, the power that propels your space-vessel, your attractors, your repellers, your object-compass, your zone of force—all these things are simply a few of the many hundreds of wave-bands of the fourth order, all of which you doubtless would have worked out for yourselves in time. Very little is known, even in theory, of the rays of the fifth order, although they have been shown to exist."
"For a man having no knowledge, you seem to know a lot about rays. How about the fifth order—is that as far as they go?"
"My knowledge is slight and very general; only such as I must have in order to understand my own subject. The fifth order certainly is not the end—it is probably scarcely a beginning. We think now that the orders extend to infinite smallness, just as the galaxies are grouped into larger aggregations, which are probably in their turn only tiny units in a scheme infinitely large.
"Over six thousand years ago the last third order rays were worked out; and certain peculiarities in their behavior led the then Rovol to suspect the existence of the fourth order. Successive generations of the Rovol proved their existence, determined the conditions of their liberation, and found that this metal of power was the only catalyst able to decompose matter and thus liberate the rays. This metal, which was called Rovolon after the Rovol, was first described upon theoretical grounds and later was found, by spectroscopy, in certain stars, notably in one star only eight light-years away, but not even the most infinitesimal trace of it exists in our entire solar system. Since these discoveries, the many Rovol have been perfecting the theory of the fourth order, beginning that of the fifth, and waiting for your coming. The present Rovol, like myself and many others whose work is almost at a standstill, is waiting with all-consuming interest to greet you, as soon as theSkylarkcan be landed upon our planet."
"Neither your rocket-ships nor your projections could get you any Rovolon?"
"No. Every hundred years or so someone develops a new type of rocket that he thinks may stand a slight chance of making the journey, but not one of these venturesome youths has as yet returned. Either that sun has no planets or else the rocket-ships have failed. Our projections are useless, as they can be driven only a very short distance upon our present carrier wave. With a carrier of the fifth order we could drive a projection to any point in the galaxy, since its velocity would be millions of times that of light and the power necessary reduced accordingly—but as I have said before, such waves cannot be generated without metal Rovolon."
"I hate to break this up—I'd like to listen to you talk for a week—but we're going to land pretty quick, and it looks as though we were going to land pretty hard."
"We will land soon, but not hard," replied Orlon confidently, and the landing was as he had foretold. TheSkylarkwas falling with an ever-decreasing velocity, but so fast was the descent that it seemed to the watchers as though they must crash through the roof of the huge brilliantly lighted building upon which they were dropping and bury themselves many feet in the ground beneath it. But they did not strike the observatory. So incredibly accurate were the calculations of the Norlaminian astronomer and so inhumanly precise were the controls he had set upon their bar, that, as they touched the ground after barely clearing the domed roof and he shut off their power, the passengers felt only a sudden decrease in acceleration, like that following the coming to rest of a rapidly moving elevator, after it has completed a downward journey.
"I shall join you in person very shortly," Orlon said, and the projection vanished.
"Well, we're here, folks, on another new world. Not quite as thrilling as the first one was, is it?" and Seaton stepped toward the door.
"How about the air composition, density, gravity, temperature, and so on?" asked Crane. "Perhaps we should make a few tests."
"Didn't you get that on the educator? Thought you did. Gravity a little less than seven-tenths. Air composition, same as Osnome and Dasor. Pressure, half-way between Earth and Osnome. Temperature, like Osnome most of the time, but fairly comfortable in the winter. Snow now at the poles, but this observatory is only ten degrees from the equator. They don't wear clothes enough to flag a hand-car with here, either, except when they have to. Let's go!"
He opened the door and the four travelers stepped out upon a close-cropped lawn—a turf whose blue-green softness would shame an Oriental rug. The landscape was illuminated by a soft and mellow, yet intense green light which emanated from no visible source. As they paused and glanced about them, they saw that theSkylarkhad alighted in the exact center of a circular enclosure a hundred yards in diameter, walled by row upon row of shrubbery, statuary, and fountains, all bathed in ever-changing billows of light. At only one point was the circle broken. There the walls did not come together, but continued on to border a lane leading up to the massive structure of cream-and-green marble, topped by its enormous, glassy dome—the observatory of Orlon.
"Welcome to Norlamin, Terrestrials," the deep, calm voice of the astronomer greeted them, and Orlon in the flesh shook hands cordially in the American fashion with each of them in turn, and placed around each neck a crystal chain from which depended a small Norlaminian chronometer-radiophone. Behind him there stood four other old men.
"These men are already acquainted with each of you, but you do not as yet know them. I present Fodan, Chief of the Five of Norlamin. Rovol, about whom you know. Astron, the First of Energy. Satrazon, the First of Chemistry."
Orlon fell in beside Seaton and the party turned toward the observatory. As they walked along the Earth-people stared, held by the unearthly beauty of thegrounds. The hedge of shrubbery, from ten to twenty feet high, and which shut out all sight of everything outside it, was one mass of vivid green and flaring crimson leaves; each leaf and twig groomed meticulously into its precise place in a fantastic geometrical scheme. Just inside this boundary there stood a ring of statues of heroic size. Some of them were single figures of men and women; some were busts; some were groups in natural or allegorical poses—all were done with consummate skill and feeling. Between the statues there were fountains, magnificent bronze and glass groups of the strange aquatic denizens of this strange planet, bathed in geometrically shaped sprays, screens, and columns of water. Winding around between the statues and the fountains there was a moving, scintillating wall, and upon the waters and upon the wall there played torrents of color, cataracts of harmoniously blended light. Reds, blues, yellows, greens—every color of their peculiar green spectrum and every conceivable combination of those colors writhed and flamed in ineffable splendor upon those deep and living screens of falling water and upon that shimmering wall.
As they entered the lane, Seaton saw with amazement that what he had supposed a wall, now close at hand, was not a wall at all. It was composed of myriads of individual sparkling jewels, of every known color, for the most part self-luminous; and each gem, apparently entirely unsupported, was dashing in and out and along among its fellows, weaving and darting here and there, flying at headlong speed along an extremely tortuous, but evidently carefully calculated course.
"What can that be, anyway, Dick?" whispered Dorothy, and Seaton turned to his guide.
"Pardon my curiosity, Orlon, but would you mind explaining the why of that moving wall? We don't get it."
"Not at all. This garden has been the private retreat of the family of Orlon for many thousands of years, and women of our house have been beautifying it since its inception. You may have observed that the statuary is very old. No such work has been done for ages. Modern art has developed along the lines of color and motion, hence the lighting effects and the tapestry wall. Each gem is held upon the end of a minute pencil of force, and all the pencils are controlled by a machine which has a key for every jewel in the wall."
Crane, the methodical, stared at the innumerable flashing jewels and asked, "It must have taken a prodigious amount of time to complete such an undertaking?"
"It is far from complete; in fact, it is scarcely begun. It was started only about four hundred years ago."
"Four hundred years!" exclaimed Dorothy. "Do you live that long? How long will it take to finish it, and what will it be like when it is done?"
"No, none of us live longer than about one hundred and sixty years—at about that age most of us decide to pass. When this tapestry wall is finished, it will not be simply form and color, as it is now. It will be a portrayal of the history of Norlamin from the first cooling of the planet. It will, in all probability, require thousands of years for its completion. You see, time is of little importance to us, and workmanship is everything. My companion will continue working upon it until we decide to pass; my son's companion may continue it. In any event, many generations of the women of the Orlon will work upon it until it is complete. When it is done, it will be a thing of beauty as long as Norlamin shall endure."
"But suppose that your son's wife isn't that kind of an artist? Suppose she should want to do music or painting or something else?" asked Dorothy, curiously.
"That is quite possible; for, fortunately, our art is not yet entirely intellectual, as is our music. There are many unfinished artistic projects in the house of Orlon, and if the companion of my son should not find one to her liking, she will be at liberty to continue anything else she may have begun, or to start an entirely new project of her own."
"You have a family, then?" asked Margaret, "I'm afraid I didn't understand things very well when you gave them to us over the educator."
"I sent things too fast for you, not knowing that your educator was new to you; a thing with which you were not thoroughly familiar. I will therefore explain some things in language, since you are not familiar with the mechanism of thought transference. The Five, a self-perpetuating body, do what governing is necessary for the entire planet. Their decrees are founded upon self-evident truth, and are therefore the law. Population is regulated according to the needs of the planet, and since much work is now in progress, an increase in population was recommended by the Five. My companion and I therefore had three children, instead of the customary two. By lot it fell to us to have two boys and one girl. One of the boys will assume my duties when I pass; the other will take over a part of some branch of science that has grown too complex for one man to handle as a specialist should. In fact, he has already chosen his specialty and been accepted for it—he is to be the nine hundred and sixty-seventh of Chemistry, the student of the asymmetric carbon atom, which will thus be his specialty from this time henceforth.
"It was learned long ago that the most perfect children were born of parents in the full prime of mental life, that is, at one hundred years of age. Therefore, with us each generation covers one hundred years. The first twenty-five years of a child's life are spent at home with his parents, during which time he acquires his elementary education in the common schools. Then boys and girls alike move to the Country of Youth, where they spend another twenty-five years. There they develop their brains and initiative by conducting any researches they choose. Most of us, at that age, solve all the riddles of the Universe, only to discover later that our solutions have been fallacious. However, much really excellent work is done in the Country of Youth, primarily because of the new and unprejudiced viewpoints of the virgin minds there at work. In that country also each finds his life's companion, the one necessary to round out mere existence into a perfection of living that no person, man or woman, can ever know alone. I need not speak to you of the wonders of love or of the completion and fullness of life that it brings, for all four of you, children though you are, know love in full measure.
"At fifty years of age the man, now mentally mature, is recalled to his family home, as his father's brain is now losing some of its vigor and keenness. The father then turns over his work to the son by means of the educator—and when the weight of the accumulated knowledge of a hundred thousand generations of research is impressed upon the son's brain, his play is over."
"What does the father do then?"
"Having made his brain record, about which I have told you, he and his companion—for she has in similar fashion turned over her work to her successor—retire to the Country of Age, where they rest and relax after their century of effort. They do whatever they care to do, for as long as they please to do it. Finally, after assuring themselves that all is well with the children, they decide that they are ready for the Change. Then, side by side as they have labored, they pass."
Now at the door of the observatory, Dorothy paused and shrank back against Seaton, her eyes widening as she stared at Orlon.
"No, daughter, why should we fear the Change?" he answered her unspoken question, calm serenity in every inflection of his quiet voice. "The life-principle is unknowable to the finite mind, as is the All-Controlling Force. But even though we know nothing of the sublime goal toward which it istending, any person ripe for the Change can, and of course does, liberate the life-principle so that its progress may be unimpeded."
In a spacious room of the observatory, in which the Terrestrials and their Norlaminian hosts had been long engaged in study and discussion, Seaton finally rose and extended a hand toward his wife.
"Well, that's that, then, Orlon, I guess. We've been thirty hours without sleep, and for us that's a long time. I'm getting so dopey I can't think a lick. We'd better go back to theSkylarkand turn in, and after we've slept nine hours or so I'll go over to Rovol's laboratory and Crane'll come back here to you."
"You need not return to your vessel," said Orlon. "I know that its somewhat cramped quarters have become irksome. Apartments have been prepared here for you. We shall have a meal here together, and then we shall retire, to meet again tomorrow."
As he spoke, a tray laden with appetizing dishes appeared in the air in front of each person. As Seaton resumed his seat the tray followed him, remaining always in the most convenient position.
Crane glanced at Seaton questioningly, and Satrazon, the First of Chemistry, answered his thought before he could voice it.
"The food before you, unlike that which is before us ofNorlamin, is wholesome for you. It contains no copper, no arsenic, no heavy metals—in short, nothing in the least harmful to your chemistry. It is balanced as to carbohydrates, proteins, fats and sugars, and contains the due proportion of each of the various accessory nutritional factors. You will also find the flavors are agreeable to each of you."
"Synthetic, eh? You've got us analyzed," Seaton stated, rather than asked, as with knife and fork he attacked the thick, rare, and beautifully broiled steak which, with its mushrooms and other delicate trimmings, lay upon his rigid although unsupported tray—noticing as he did so that the Norlaminians ate with tools entirely different from those they had supplied to their Earthly guests.
"Entirely synthetic," Satrazon made answer, "except for the sodium chloride necessary. As you already know, sodium and chlorin are very rare throughout our system, therefore the force upon the food-supply took from your vessel the amount of salt required for the formula. We have been unable to synthesize atoms, for the same reason that the labors of so many others have been hindered—because of the lack of Rovolon. Now, however, my science shall progress as it should; and for that I join with my fellow scientists in giving you thanks for the service you have rendered us."
"We thank you instead," replied Seaton, "for the service we have been able to do you is slight indeed compared to what you are giving us in return. But it seems that you speak quite impersonally of the force upon the food supply. Did you yourself direct the preparation of these meats and vegetables?"
"Oh, no. I merely analyzed your tissues, surveyed the food-supplies you carried, discovered your individual preferences, and set up the necessary integrals in the mechanism. The forces did the rest, and will continue to do so as long as you remain upon this planet."
"Fruit salad always my favorite dish," Dorothy said, after a couple of bites, "and this one is just too perfectly divine! It doesn't taste like any other fruit I ever ate, either—I think it must be the same ambrosia that the old pagan gods used to eat."
"If all you did was to set up the integrals, how do you know what you are going to have for the next meal?" asked Crane.
"We have no idea what the form, flavor, or consistency of any dish will be," was the surprising answer. "We know only that the flavor will be agreeable and that it will agree with the form and consistency of the substance, and that the composition will be well-balanced chemically. You see, all the details of flavor, form, texture, and so on are controlled by a device something like one of your kaleidoscopes. The integrals render impossible any unwholesome, unpleasant, or unbalanced combination of any nature, and everything else is left to the mechanism, which operates upon pure chance."
"Some system, I'd rise to remark," and Seaton, with the others, resumed his vigorous attack upon the long-delayed supper.
The meal over, the Earthly visitors were shown to their rooms, and fell into a deep, dreamless sleep.
Breakfast over, Seaton watched intently as his tray, laden with empty containers, floated away from him and disappeared into an opening in the wall.
"How do you do it, Orlon?" he asked, curiously. "I can hardly believe it, even after seeing it done."
"Each tray is carried upon the end of a beam or rod of force, and supported rigidly by it. Since the beam is tuned to the individual wave of the instrument you wear upon your chest, your tray is, of course, placed in front of you, at a predetermined distance, as soon as the sending force is actuated. When you have finished your meal, the beam is shortened. Thus the tray is drawn back to the food laboratory, where other forces cleanse and sterilize the various utensils and place them in readiness for the next meal. It would be an easy matter to have this same mechanism place your meals before you wherever you may go upon this planet, provided only that a clear path can be plotted from the laboratory to your person."
"Thanks, but it wouldn't pay. No telling where we'd be. Besides, we'd better eat in theSkylarkmost of thetime, to keep our cook good-natured. Well, I see Rovol's got his boat here for me, so guess I'd better turn up a few r. p. m. Coming along, Dot, or have you got something else on your mind?"
"I'm going to leave you for a while. I can't really understand even a radio, and just thinking about those funny, complicated rays and things you are going after makes me dizzy in the head. Mrs. Orlon is going to take us over to the Country of Youth—she says Margaret and I can play around with her daughter and her bunch and have a good time while you scientists are doing your stuff."
"All right. 'Bye till tonight," and Seaton stepped out into the grounds, where the First of Rays was waiting.
The flier was a torpedo-shaped craft of some transparent, glassy material, completely enclosed except for one circular opening or doorway. From the midsection, which was about five feet in diameter and provided with heavily-cushioned seats capable of carrying four passengers in comfort, the hull tapered down smoothly to a needle point at each end. As Seaton entered and settled himself into the cushions, Rovol touched a lever. Instantly a transparent door slid across the opening, locking itself into position flush with the surface of the hull, and the flier darted into the air and away. For a few minutes there was silence, as Seaton studied the terrain beneath them. Fields or cities there were none; the land was covered with dense forests and vast meadows, with here and there great buildings surrounded by gracious, park-like areas. Rovol finally broke the silence.
"I understand your problem, I believe, since Orlon has transferred to me all the thoughts he had from you. With the aid of the Rovolon you have brought us, I am confident that we shall be able to work out a satisfactory solution of the various problems involved. It will take us some few minutes to traverse the distance to my laboratory, and if there are any matters upon which your mind is not quite clear, I shall try to clarify them."
"That's letting me down easy," Seaton grinned, "but you don't need to be afraid of hurting my feelings—I know just exactly how ignorant and dumb I am compared to you. There's a lot of things I don't get at all. First, and nearest, this airboat. It has no power-plant at all. I assume that it, like so many other things hereabouts, is riding on the end of a rod of force?"
"Exactly. The beam is generated and maintained in my laboratory. All that is here in the flier is a small sender, for remote control."
"How do you obtain your power?" asked Seaton. "Solar generators and tide motors? I know that all your work is done by protelectricity, but Orlon did not inform us as to the sources."
"We have not used such inefficient generators for many thousands of years. Long ago it was shown by research that these rays were constantly being generated in abundance in outer space, and that they could be collected upon spherical condensers and transmitted without loss to the surface of the planet by means of matched and synchronized crystals. Several millions of these condensers have been built and thrown out to become tiny satellites of Norlamin."
"How did you get them far enough out?"
"The first ones were forced out to the required distance upon beams of force produced by the conversion of electricity, which was in turn produced from turbines, solar motors, and tide motors. With a few of them out, however, it was easy to obtain sufficient power to send out more; and now, whenever one of us requires more power than he has at his disposal, he merely sends out such additional collectors as he needs."
"Now about those fifth-order rays, which will penetrate a zone of force. I am told that they are not ether waves at all?"
"They are not ether waves. The fourth order rays, of which the theory has been completely worked out, are the shortest vibrations that can be propagated through the ether; for the ether itself is not a continuous medium. We do not know its nature exactly, but it is an actual substance, and is composed of discrete particles of the fourth order. Now the zone of force, which is itself a fourth-order phenomenon, sets up a condition of stasis in the particles composing the ether. These particles are relatively so coarse, that rays and particles of the fifth order will pass through the fixed zone without retardation. Therefore, if there is anything between the particles of the ether—this matter is being debated hotly among us at the present time—it must be a sub-ether, if I may use that term. We have never been able to investigate any of these things experimentally, not even such a coarse aggregation as is the ether; but now, having Rovolon, it will not be many thousands of years until we shall have extended our knowledge many orders farther, in both directions."
"Just how will Rovolon help you?"
"It will enable us to generate a force of the ninth magnitude—that much power is necessary to set up what you have so aptly named a zone of force—and will give us a source of fourth, fifth, and probably higher orders of rays which, if they are generated in space at all, are beyond our present reach. The zone of force is necessary to shield certain items of equipment from ether vibrations; as any such vibration inside the controlling fields of force renders observation or control of the higher orders of rays impossible."
"Hm ... m, I see—I'm learning something," Seaton replied cordially. "Just as the higher-powered a radio set is, the more perfect must be its shielding?"
"Yes. Just as a trace of any gas will destroy the usefulness of your most sensitive vacuum tubes, and just as imperfect shielding will allow interfering waves to enter sensitive electrical apparatus—in that same fashion will even the slightest ether vibration interfere with the operation of the extremely sensitive fields and lenses of force which must be used in controlling forces of the higher orders."
"You haven't tested the theory of the fourth order yet, have you?"
"No, but that is unnecessary. The theory of the fourth order is not really theory at all—it is mathematical fact. Although we have never been able to generate them, we know exactly the forces you use in your ship of space, and we can tell you of some thousands of others more or less similar and also highly useful forces which you have not yet discovered, but are allowing to go to waste. We know exactly what they are, how to liberate and control them, and how to use them. In fact, in the work which we are to begin today, we shall use but little ordinary power: almost all our work will be done by fourth-order forces, liberated from copper by means of the Rovolon you have given me. But here we are at my laboratory. You already know that the best way to learn is by doing, and we shall begin at once."
The flier alighted upon a lawn quite similar to the one before the observatory of Orlon, and the scientist led his Earthly guest through the main entrance of the imposing structure of vari-colored marble and gleaming metal and into the vast, glass-lined room that was his laboratory. Great benches lined the walls, and there were hundreds of dials, meters, tubes, transformers and other instruments, whose uses Seaton could not even guess.
Rovol first donned a suit of transparent, flexible material, of a deep golden color, instructing Seaton to do the same; explaining that much of the work would be with dangerous frequencies and with high pressures, and that the suits were not only absolute insulators against electricity, heat, and sound, but were also ray-filters proof against any harmful radiations. As each helmet was equipped with radiophones, conversation was not interfered with in the least.
Rovol took up a tiny flash-pencil, and with it deftly cut off a bit of Rovolon, almost microscopic in size. This he placed upon a great block of burnished copper, and upon it played a force. As he manipulated two levers, two more beams of force flattened out the particle of metal, spread it out over the copper, and forced it into the surface of the block until the thin coating was at every point in molecular contact with the copper beneath it—a perfect job of plating, and one done in the twinkling of an eye. He then cut out a piece of the treated copper the size of a pea, and other forces rapidly built around it a structure of coils and metallic tubes. This apparatus he suspended in the air at the extremity of a small beam of force. The block of copper was next cut in two, and Rovol's fingers moved rapidly over the keys of a machine which resembled slightly an overgrown and exceedingly complicated book-keeping machine. Streams and pencils of force flashed and crackled, and Seaton saw raw materials transformed into a complete power-plant, in its center the two-hundred-pound lump of plated copper, where an instant before there had been only empty space upon the massive metal bench. Rovol's hands moved rapidly from keys to dials and back, and suddenly a zone of force, as large as a basketball appeared around the apparatus poised in the air.
"But it'll fly off and we can't stop it with anything," Seaton protested, and it did indeed dart rapidly upward.
The old man shook his head as he manipulated still more controls, and Seaton gasped as nine stupendous beams of force hurled themselves upon that brilliant spherical mirror of pure energy, seized it in mid-flight, and shaped it resistlessly, under his bulging eyes, into a complex geometrical figure of precisely the desired form.
Lurid violet light filled the room, and Seaton turned towards the bar. That two-hundred-pound mass of copper was shrinking visibly, second by second, so vast were the forces being drawn from it, and the searing, blinding light would have been intolerable but for the protective color-filters of his helmet. Tremendous flashes of lightning ripped and tore from the relief-points of the bench to the ground-rods, which flared at blue-white temperature under the incessant impacts. Knowing that this corona-loss was but an infinitesimal fraction of the power being used, Seaton's very mind staggered as he strove to understand the magnitude of the forces at work upon that stubborn sphere of energy.
The aged scientist used no tools whatever, as we understand the term. His laboratory was a power-house; at his command were the stupendous forces of a battery of planetoid accumulators, and added to these were the fourth-order, ninth-magnitude forces of the disintegrating copper bar. Electricity, protelectricity, and fourth-order rays, under millions upon millions of kilovolts of pressure, leaped to do the bidding of that wonderful brain, stored with the accumulated knowledge of countless thousands of years of scientific research. Watching the ancient physicist work, Seaton compared himself to a schoolboy mixing chemicals indiscriminately and ignorantly, with no knowledge whatever of their properties, occasionally obtaining a reaction by pure chance. Whereas he had worked with intra-atomic energy schoolboy fashion, the master craftsman before him knew every reagent, every reaction, and worked with known and thoroughly familiar agencies to bring about his exactly predetermined ends—just as calmly certain of the results as Seaton himself would have been in his own laboratory, mixing equivalent quantities of solutions of barium chloride and of sulphuric acid to obtain a precipitate of barium sulphate.
Rovol teaches SeatonHour after hour Rovol labored on, oblivious to the passage of time in his zeal of accomplishment, the while carefully instructing Seaton, who watched every step with intense interest....
Hour after hour Rovol labored on, oblivious to the passage of time in his zeal of accomplishment, the while carefully instructing Seaton, who watched every step with intense interest and did everything possible for him to do. Bit by bit a towering structure arose in the middle of the laboratory. A metal foundation supported a massive compound bearing, which in turn carried a tubular network of latticed metal, mounted like an immense telescope. Near the upper, outer end of this openwork tube a group of nine forces held the field of force rigidly in place in its axis; at the lower extremity were mounted seats for two operators and the control panels necessary for the operation of the intricate system of forces and motors which would actuate and control that gigantic projector. Immense hour and declination circles could be read by optical systems from the operators' seats—circles fully forty feet in diameter, graduated with incredible delicacy and accuracy into decimal fractions of seconds of arc, and each driven by variable-speed motors through gear-trains and connections having no backlash whatever.
While Rovol was working upon one of the last instruments to be installed upon the controlling panel a mellow note sounded throughout the building, and he immediately ceased his labors and opened the master-switches of his power plants.
"You have done well, youngster," he congratulated his helper, as he began to take off his protective covering, "Without your aid I could not have accomplished nearly this much during one period of labor. The periods of exercise and of relaxation are at hand—let us return to the house of Orlon, where we all shall gather to relax and to refresh ourselves for the labors of tomorrow."
"But it's almost done!" protested Seaton. "Let's finish it up and shoot a little juice through it, just to try it out."
"There speaks the rashness and impatience of youth," rejoined the scientist, calmly removing the younger man's suit and leading him out to the waiting airboat. "I read in your mind that you are often guilty of laboring continuously until your brain loses its keen edge. Learn now, once and for all, that such conduct is worse than foolish—it is criminal. We have labored the full period. Laboring for more than that length of timewithout recuperation results in a loss of power which, if persisted in, wreaks permanent injury to the mind; and by it you gain nothing. We have more than ample time to do that which must be done—the fifth-order projector shall be completed before the warning torpedo shall have reached the planet of the Fenachrone—therefore over-exertion is unwarranted. As for testing, know now that only mechanisms built by bunglers require testing. Properly built machines work properly."
"But I'd have liked to see it work just once, anyway," lamented Seaton as the small airship tore through the air on its way back to the observatory.
"You must cultivate calmness, my son, and the art of relaxation. With those qualities your race can easily double its present span of useful life. Physical exercise to maintain the bodily tissues at their best, and mental relaxation following mental toil—these things are the secrets of a long and productive life. Why attempt to do more than can be accomplished efficiently? There is always tomorrow. I am more interested in that which we are now building than you can possibly be, since many generations of the Rovol have anticipated its construction; yet I realize that in the interest of our welfare and for the progress of civilization, today's labors must not be prolonged beyond today's period of work. Furthermore, you yourself realize that there is no optimum point at which any task may be interrupted. Short of final completion of any project, one point is the same as any other. Had we continued, we would have wished to continue still farther, and so on without end."
"You're probably right, at that," the impetuous chemist conceded, as their craft came to earth before the observatory.
Crane and Orlon were already in the common room, as were the scientists Seaton already knew, as well as a group of women and children still strangers to the Terrestrials. In a few minutes Orlon's companion, a dignified, white-haired woman, entered; accompanied by Dorothy, Margaret, and a laughing, boisterous group of men and women from the Country of Youth. Introductions over, Seaton turned to Crane.
"How's every little thing, Mart?"
"Very well indeed. We are building an observatory in space—or rather, Orlon is building it and I am doing what little I can to help him. In a few days we shall be able to locate the system of the Fenachrone. How is your work progressing?"
"Smoother than a kitten's ear. Got the fourth-order projector about done. We're going to project a fourth-order force out to grab us some dense material, a pretty close approach to pure neutronium. There's nothing dense enough around here, even in the core of the central sun, so we're going out to a white dwarf star—one a good deal like the companion star to Sirius in Canis Major—get some material of the proper density from its core, and convert our sender into a fifth-order machine. Then we can really get busy—go places and do things."
"Neutronium? Pure mass?" queried Crane, "I have been under the impression that it does not exist. Of what use can such a substance be to you?"
"Can't get pure neutronium, of course—couldn't use it if we could. What we need and are going to get is a material of about two and a half million specific gravity. Got to have it for lenses and controls for the fifth-order forces. Those rays go right through anything less dense without measurable refraction. But I see Rovol's giving me a nasty look. He's my boss on this job, and I imagine this kind of talk's barred during the period of relaxation, as being work. That so, chief?"
"You know that it is barred, you incorrigible young cub!" answered Rovol, with a smile.
"All right, boss; one more little infraction and I'll shut up like a clam. I'd like to know what the girls have been doing."
"We've been having a wonderful time!" Dorothy declared. "We've been designing fabrics and ornaments and jewels and things. Wait 'til you see 'em!"
"Fine! All right, Orlon, it's your party—what to do?"
"This is the time of exercise. We have many forms, most of which are unfamiliar to you. You all swim, however, and as that is one of the best of exercises, I suggest that we all swim."
"Lead us to it!" Seaton exclaimed, then his voice changed abruptly. "Wait a minute—I don't know about our swimming in copper sulphate solution."
"We swim in fresh water as often as in salt, and the pool is now filled with distilled water."
The Terrestrials quickly donned their bathing suits and all went through the observatory and down a winding path, bordered with the peculiarly beautiful scarlet and green shrubbery, to the "pool"—an artificial lake covering a hundred acres, its polished metal bottom and sides strikingly decorated with jewels and glittering tiles in tasteful yet contrasting inlaid designs. Any desired depth of water was available and plainly marked, from the fenced-off shallows where the smallest children splashed to the forty feet of liquid crystal which received the diver who cared to try his skill from one of the many spring-boards, flying rings, and catapults which rose high into the air a short distance away from the entrance.
Orlon and the others of the older generation plunged into the water without ado and struck out for the other shore, using a fast double-overarm stroke. Swimming in a wide circle they came out upon the apparatus and went through a series of methodical dives and gymnastic performances. It was evident that they swam, as Orlon had intimated, for exercise. To them, exercise was a necessary form of labor—labor which they performed thoroughly and well—but nothing to call forth the whole-souled enthusiasm they displayed in their chosen fields of mental effort.
The visitors from the Country of Youth, however, locked arms and sprang to surround the four Terrestrials, crying, "Let's do a group dive!"
"I don't believe that I can swim well enough to enjoy what's coming," whispered Margaret to Crane, and they slipped into the pool and turned around to watch. Seaton and Dorothy, both strong swimmers, locked arms and laughed as they were encircled by the green phalanx and swept out to the end of a dock-like structure and upon a catapult.
"Hold tight, everybody!" someone yelled, and interlaced, straining arms and legs held the green and white bodies in one motionless group as a gigantic force hurled them fifty feet into the air and out over the deepest part of the pool. There was a mighty splash and a miniature tidal wave as that mass of humanity struck the water. Many feet they went down before the cordon was broken and the individual units came to the surface. Then pandemonium reigned. Vigorous informal games, having to do with floating and sinking balls and effigies: pushball, in which the players never seemed to know, or to care, upon which side they were playing; water-fights and ducking contests.... A green mermaid, having felt the incredible power of Seaton's arms as he tossed her lightly away from a goal he was temporarily defending, put both her small hands around his biceps wonderingly, amazed at a strength unknown and impossible upon her world; then playfully tried to push him under. Failing, she called for help.
"He's needed a good ducking for ages!" Dorothycried, and she and several other girls threw themselves upon him. Over and around him the lithe forms flashed, while the rest of the young people splashed water impartially over all the combatants and cheered them on. In the midst of the battle the signal sounded to end the period of exercise.
"Saved by the bell," Seaton laughed as, thoroughly ducked and almost half drowned, he was allowed to swim ashore.
When all had returned to the common room of the observatory and had seated themselves, Orlon took out his miniature ray-projector, no larger than a fountain pen, and flashed it briefly upon one of the hundreds of button-like lenses upon the wall. Instantly each chair converted itself into a form-fitting divan, inviting complete repose.
"I believe that you of Earth would perhaps enjoy some of our music during this, the period of relaxation and repose—it is so different from your own," Orlon remarked, as he again manipulated his tiny force-tube.
Every light was extinguished and there was felt a profoundly deep vibration—a note so low as to be palpable rather than audible; and simultaneously the utter darkness was relieved by a tinge of red so dark as to be barely perceptible, while a peculiar somber fragrance pervaded the atmosphere. The music rapidly ran the gamut to the limit of audibility and, in the same tempo, the lights traversed the visible spectrum and disappeared. Then came a crashing chord and a vivid flare of blended light; ushering in an indescribable symphony of sound and color, accompanied by a slower succession of shifting, blending odors.
The quality of tone was now that of a gigantic orchestra, now that of a full brass band, now that of a single unknown instrument—as though the composer had had at his command every overtone capable of being produced by any possible instrument, and with them had woven a veritable tapestry of melody upon an incredibly complex loom of sound. As went the harmony, so the play of light accompanied it. Neither music nor illumination came from any apparent source; they simply pervaded the entire room. When the music was fast—and certain passages were of a rapidity impossible for any human fingers to attain—the lights flashed in vivid, tiny pencils, intersecting each other in sharply drawn, brilliant figures, which changed with dizzying speed; when the tempo was slow, the beams were soft and broad, blending into each other to form sinuous, indefinite, writhing patterns, whose very vagueness was infinitely soothing.
"What do you think of it, Mrs. Seaton?" Orlon asked.
"Marvelous!" breathed Dorothy, awed. "I never imagined anything like it. I can't begin to tell you how much I like it. I never dreamed of such absolute perfection of execution, and the way the lighting accompanies the theme is just too perfectly wonderful for words! It was incredibly brilliant."
"Brilliant—yes. Perfectly executed—yes. But I notice that you say nothing of depth of feeling or of emotional appeal." Dorothy blushed uncomfortably and started to say something, but Orlon silenced her and continued: "You need not apologize. I had a reason for speaking as I did, for in you I recognize a real musician, and our music is indeed entirely soulless. That is the result of our ancient civilization. We are so old that our music is purely intellectual, entirely mechanical, instead of emotional. It is perfect, but, like most of our other arts, it is almost completely without feeling."
"But your statues are wonderful!"
"As I told you, those statues were made myriads of years ago. At that time we also had real music, but, unlike statuary, music at that time could not be preserved for posterity. That is another thing you have given us. Attend!"
At one end of the room, as upon a three-dimensional screen, the four Terrestrials saw themselves seated in the control-room of theSkylark. They saw and heard Margaret take up her guitar, and strike four sonorous chords in "A." Then, as if they had been there in person, they heard themselves sing "The Bull-Frog" and all the other songs they had sung, far off in space. They heard Margaret suggest that Dorothy play some "real music," and heard Seaton's comments upon the quartette.
"In that, youngster, you were entirely wrong," said Orlon, stopping the reproduction for a moment. "The entire planet was listening to you very attentively—we were enjoying it as no music has been enjoyed for thousands of years."
"The whole planet!" gasped Margaret. "Were you broadcasting it? How could you?"
"Easy," grinned Seaton. "They can do most anything with these rays of theirs."
"When you have time, in some period of labor, we would appreciate it very much if you four would sing for us again, would give us more of your vast store of youthful music, for we can now preserve it exactly as it is sung. But much as we enjoyed the quartette, Mrs. Seaton, it was your work upon the violin that took us by storm. Beginning with tomorrow, my companion intends to have you spend as many periods as you will, playing for our records. We shall now have your music."
"If you like it so well, wouldn't you rather I'd play you something I hadn't played before?"
"That is labor. We could not...."
"Piffle!" Dorothy interrupted. "Don't you see that I could really play right now, with somebody to listen, who really enjoys music; whereas, if I tried to play in front of a record, I'd be perfectly mechanical?"
"'At-a-girl, Dot! I'll get your fiddle."
"Keep your seat, son," instructed Orlon, as the case containing the Stradivarius appeared before Dorothy, borne by a pencil of force. "While that temperament is incomprehensible to every one of us, it is undoubtedly true that the artistic mind does work in that manner. We listen."
Dorothy swept into "The Melody in F," and as the poignantly beautiful strains poured forth from that wonderful violin, she knew that she had her audience with her. Though so intellectual that they themselves were incapable of producing music of real depth of feeling, they could understand and could enjoy such music with an appreciation impossible to a people of lesser mental attainments; and their profound enjoyment of her playing, burned into her mind by the telepathic, almost hypnotic power of the Norlaminian mentality, raised her to heights of power she had never before attained. Playing as one inspired, she went through one tremendous solo after another—holding her listeners spellbound, urged on by their intense feeling to carry them further and ever further into the realm of pure emotional harmony. The bell which ordinarily signaled the end of the period of relaxation did not sound; for the first time in thousands of years the planet of Norlamin deserted its rigid schedule of life—to listen to one Earth-woman, pouring out her very soul upon her incomparable violin.
The final note of "Memories" died away in a diminuendo wail, and the musician almost collapsed into Seaton's arms. The profound silence, more impressive far than any possible applause, was soon broken by Dorothy.
"There—I'm all right now, Dick. I was about outof control for a minute. I wish they could have had that on a recorder—I'll never be able to play like that again if I live to be a thousand years old."
"It is on record, daughter. Every note and every inflection is preserved, precisely as you played it," Orlon assured her. "That is our only excuse for allowing you to continue as you did, almost to the point of exhaustion. While we cannot really understand an artistic mind of the peculiar type to which yours belongs, yet we realized that each time you play you are doing something that no one, not even yourself, can ever do again in precisely the same subtle fashion. Therefore we allowed, in fact encouraged, you to go on as long as that creative impulse should endure—not merely for our pleasure in hearing it, great though that pleasure was, but in the hope that our workers in music could, by a careful analysis of your product, determine quantitatively the exact vibrations or overtones which make the difference between emotional and intellectual music."
