The quality of tone was now that of a gigantic orchestra, now that of a full bra.s.s 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 pa.s.sages 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 the _Skylark_.

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 s.p.a.ce. 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, d.i.c.k. I was about out of 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 a.s.sured 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 a.n.a.lysis of your product, determine quant.i.tatively the exact vibrations or overtones which make the difference between emotional and intellectual music."

CHAPTER XI

Into a Sun

As Rovol and Seaton approached the physics laboratory at the beginning of the period of labor, another small airboat occupied by one man drew up beside them and followed them to the ground. The stranger, another white-bearded ancient, greeted Rovol cordially and was introduced to Seaton as "Caslor, the First of Mechanism."

"Truly, this is a high point in the course of Norlaminian science, my young friend," Caslor acknowledged the introduction smilingly. "You have enabled us to put into practice many things which our ancestors studied in theory for many a wearisome cycle of time." Turning to Rovol, he went on: "I understand that you require a particularly precise directional mechanism? I know well that it must indeed be one of exceeding precision and delicacy, for the controls you yourself have built are able to hold upon any point, however moving, within the limits of our immediate solar system."

"We require controls a million times as delicate as any I have constructed," said Rovol, "therefore I have called your surpa.s.sing skill into co-operation. It is senseless for me to attempt a task in which I would be doomed to failure. We intend to send out a fifth-order projection, something none of our ancestors ever even dreamed of, which, with its inconceivable velocity of propagation, will enable us to explore any region in the galaxy as quickly as we now visit our closest sister planet. Knowing the dimensions of this, our galaxy, you can readily understand the exact degree of precision required to hold upon a point at its outermost edge."

"Truly, a problem worthy of any man's brain," Caslor replied after a moment's thought. "Those small circles," pointing to the forty-foot hour and declination circles which Seaton had thought the ultimate in precise measurement of angular magnitudes, "are of course useless. I shall have to construct large and accurate circles, and in order to produce the slow and fast motions of the required nature, without creep, slip, play, or backlash, I shall require a pure torque, capable of being increased by infinitesimal increments.... Pure torque."

He thought deeply for a time, then went on: "No gear-train or chain mechanism can be built of sufficient tightness, since in any mechanism there is some freedom of motion, however slight, and for this purpose the director must have no freedom of motion whatever. We must have a pure torque--and the only possible force answering our requirements is the four hundred sixty-seventh band of the fourth order. I shall therefore be compelled to develop that band. The director must, of course, have a full equatorial mounting, with circles some two hundred and fifty feet in diameter. Must your projector tube be longer than that, for correct design?"

"That length will be ample."

"The mounting must be capable of rotation through the full circle of arc in either plane, and must be driven in precisely the motion required to neutralize the motion of our planet, which, as you know, is somewhat irregular. Additional fast and slow motions must, of course, be provided to rotate the mechanism upon each graduated circle at the will of the operator. It is my idea to make the outer supporting tube quite large, so that you will have full freedom with your inner, or projector tube proper. It seems to me that dimensions X37 B42 J867 would perhaps be as good as any."

"Perfectly satisfactory. You have the apparatus well in mind."

"These things will consume some time. How soon will you require this mechanism?" asked Caslor.

"We also have much to do. Two periods of labor, let us say: or, if you require them, three."

"It is well. Two periods will be ample time: I was afraid that you might need it today, and the work cannot be accomplished in one period of labor. The mounting will, of course, be prepared in the Area of Experiment. Farewell."

"You aren't going to build the final projector here, then?" Seaton asked as Caslor's flier disappeared.

"We shall build it here, then transport it to the Area, where its dirigible housing will be ready to receive it. All mechanisms of that type are set up there. Not only is the location convenient to all interested, but there are to be found all necessary tools, equipment and material. Also, and not least important for such long-range work as we contemplate, the entire Area of Experiment is anch.o.r.ed immovably to the solid crust of the planet, so that there can be not even the slightest vibration to affect the direction of our beams of force, which must, of course, be very long."

He closed the master switches of his power-plants and the two resumed work where they had left off. The control panel was soon finished. Rovol then plated an immense cylinder of copper and placed it in the power-plant. He next set up an entirely new system of refractory relief-points and installed additional ground-rods, sealed through the floor and extending deep into the ground below, explaining as he worked.

"You see, son, we must lose one one-thousandth of one per cent of our total energy, and provision must be made for its dissipation in order to avoid destruction of the laboratory. These air-gap resistances are the simplest means of disposing of the wasted power."

"I get you--but say, how about disposing of it when we get the thing in a ship out in s.p.a.ce? We picked up pretty heavy charges in the _Skylark_--so heavy that I had to hold up several times in the ionized layer of an atmosphere while they faded--and this outfit will burn up tons of copper where the old ones used ounces."

"In the projected s.p.a.ce-vessel we shall install converters to utilize all the energy, so that there will be no loss whatever. Since such converters must be designed and built especially for each installation, and since they require a high degree of precision, it is not worth while to construct them for a purely temporary mechanism, such as this one."

The walls of the laboratory were opened, ventilating blowers were built, and refrigerating coils were set up everywhere, even in the tubular structure and behind the visiplates. After a.s.suring themselves that everything combustible had been removed, the two scientists put on under their helmets, goggles whose protecting lenses could be built up to any desired thickness. Rovol then threw a switch, and a hemisphere of flaming golden radiance surrounded the laboratory and extended for miles upon all sides.

"I get most of the stuff you've pulled so far, but why such a light?"

asked Seaton.

"As a warning. This entire area will be filled with dangerous frequencies, and that light is a warning for all uninsulated persons to give our theater of operations a wide berth."

"I see. What next?"

"All that remains to be done is to take our lens-material and go,"

replied Rovol, as he took from a cupboard the largest faidon that Seaton had ever seen.

"Oh, that's what you're going to use! You know, I've been wondering about that stuff. I took one back with me to the Earth to experiment on.
