But, after a moment's consideration, he decided, that it would be far more interesting and comfortable to remain right where he was and listen to the reports which were being sent down from above.

"--thus far there seems to be no cause for alarm, and people are advised to remain calm--careful observations of the luminous monster are being made and further reports concerning it will be broadcast--"

Dirk Vanderpool rose to his feet, walked to the coping of the terrace and peered into the magnascope that was set into the wall.

He saw that the street, far below him, was jammed with struggling people and the device through which he was looking brought their faces before him in strong relief. Dirk was deeply interested and, at the same time, gravely concerned as he studied the upturned countenances in the mob.

Fear, despair, reckless abandon, mirth, doubt, religious ecstasy and all the other nuances in the gamut of human emotions and pa.s.sions were reflected in those distorted visages which were gazing skyward.

The silvery humming of a bell diverted his attention from the scene of congestion below him and, turning away, he walked across the terrace and into the great living room of his luxurious abode.

Stepping to the televisor, he turned a tiny switch, and the face of a girl appeared in the gla.s.s panel that was framed above the sound-box. He smiled as he lifted the receiver and placed it to his ear.

"What is the matter, Inga?" he asked. "You look as if you were expecting--well, almost anything disastrous."

"Oh, Dirk, what is that thing?" the girl asked. "I really am frightened!"

He could see by the expression in her blue eyes that she, too, was becoming a victim of the hysteria that was taking possession of many people.

"I wouldn't be alarmed, Inga," he replied rea.s.suringly. "I don't know what it is, and no one else seems to be able to explain it."

"But it is frightful and uncanny, Dirk," the girl insisted, "and I am sure that something terrible is going to happen. I wish," she pleaded, "that you would come over and stay with me for a little while. I am all alone and--"

"All right, Inga," he told her. "I will be with you in a few minutes."

He hung up the receiver of the televisor and clicked off the switch. The image of the golden-haired girl to whom he had been speaking slowly faded from the gla.s.s.

Attiring himself for a short sixty-mile hop down Long Island, Dirk pa.s.sed out to the landing stage and, stepping into the cabin of his plane, he threw in the helicopter lever. The machine rose straight into the air for a couple of hundred feet and then Dirk headed it westward to where the nearest ascension beam sent its red light towering toward the stars. It marked a vertical air-lane that led upward to the horizontal lanes of flight.

Northbound ships flew between two and four thousand feet; southbound planes between five and seven thousand feet; those eastbound confined themselves to the level between nine and eleven thousand feet, while the westbound flyers monopolized the air between twelve and fourteen thousand feet.

All planes flying parallel to the earth were careful to avoid those red beacons which marked ascension routes, and the shafts of green light down which descending planes dropped to the earth or into lower levels of travel.

When Dirk's altimeter indicated seventy-five hundred feet he turned the nose of his ship eastward and adjusted his rheostat until his motors, fed by wireless current, were revolving at top speed.

The great canyons of Manhattan, linked by arches and highways which joined and pa.s.sed through various levels of the stupendous structures of steelite and quartzite, pa.s.sed swiftly beneath him; and, after pa.s.sing for a few minutes over the deserted surface of Long Island, he completed his sixty-mile flight and brought his ship to a rest on a landing stage that was far up on the side of a vast pile that rose up close to the sh.o.r.e of the Sound.

As soon as he stepped from the door of the cabin he was joined by a girl who, apparently, had been lingering there, awaiting his arrival.

She was perhaps twenty years old, and she had the golden hair, the light complexion, and the blue eyes which still were characteristic of the women of northern Europe.

The slender lines of her exquisite figure and the supple grace which she displayed when she moved toward Dirk were evidence, however, of the Latin blood which was in her veins.

For Inga Fragoni, the daughter and heiress of Orlando Fragoni, seemed to be a culmination of all of the desirable qualities of the women of the south and those of the north.

The terrace on which Dirk had landed was illuminated by lights which simulated sunshine, and their soft bright glow revealed the violet hue of her eyes and the shimmering gloss of her silken hair. She wore a sleeveless, light blue tunic which was gathered around her waist with a bejeweled girdle.

On her tiny feet she wore sandals which were spun of webby filaments of gold and platinum.

"Dirk, I am so glad that you are here!" she exclaimed. "I felt so much alone when I called you up. Dad is locked in the observatory with Professor Nachbaren and three or four other men and the servants--well, they all are so terrified that it simply alarms me to have them around."

"But that is Stanton's plane there, isn't it?" asked Dirk, indicating a powerful looking machine that stood on the terrace.

"Yes, Dirk," the girl replied. "He arrived here three or four minutes before you did. I thought, at first, that it was you coming. And Dirk,"

she continued, with a note of excitement in her voice, "he flew up to look at that thing, and I know that he is as frightened about it as I am."

Dirk grunted, but he gave no expression of the dislike and distrust that Stanton aroused in him. The latter, he knew, was very much inclined to look with favor on Inga, and his presumption annoyed Dirk because, while he and the girl had not declared their intention of living together, they were very much in love with each other.

"You will want to hear him tell about it, I know, Dirk," the girl said.

"I left Stanton up on the garden terrace when I saw you coming down.

Come; we will go and join him."

Dirk and Inga strolled slowly along paths which were lined with exotic shrubbery and plants. Here and there a fountain tossed its glittering spray high into the air while birds, invisible in the feathery foliage, warbled and thrilled entrancingly. Soft music, transmitted from the auditoriums below, blended so harmoniously with the atmosphere of the terraces that it seemed to mingle with and be a part of the drifting, subtle scents of the abundant flowers which bloomed on every side.

For these upper terraces of Fragoni's palace were enclosed, during inclement weather, with great gla.s.s plates which, at the touch of a b.u.t.ton, automatically appeared or disappeared.

Winding their way easily upward, Dirk and Inga came finally to a secluded terrace which overlooked the Sound. Here they saw Stanton, who was unaware of their approach, looking skyward at the dim and sinister shape which was outlined against the sky. Stanton's brow was contracted and his expression was filled with apprehension. He started suddenly when he became conscious of the presence of Dirk and the lovely daughter of Fragoni.

He rose to his feet, a short man in his forties, stocky in build and somewhat swarthy in complexion. He contrasted very unfavorably with Dirk, who was tall and well-built and who had abundant blond hair and steady steel-blue eyes.

"What do you make of that thing, Vanderpool?" he asked, almost ignoring the presence of Inga.

"I don't know enough about it yet to be able to express an opinion,"

Dirk replied. "We will find out about it soon enough," he added, "so why worry about it in the meantime?"

"It is well enough to affect such an att.i.tude," said Stanton, with a touch of sarcasm in his voice, "but let me tell you, Vanderpool, that there is good reason to worry about it."

Dirk frowned at the statement as he saw a shadow pa.s.s over the fair face of Inga.

"That thing up there," continued Stanton, with conviction in his voice, "is not a natural phenomenon. I flew fairly close to it in my plane and I know what I am speaking about. That thing is some sort of a monster, Vanderpool, that is made of metal or of some composition that is an unearthly equivalent of metal. It is a diabolical creation of some sort that has come from out of the fathomless depths of the universe." He shuddered at the fantasy that his feverish imagination was creating. "It is metal, I tell you," he continued, "but it is metal that is endowed with some sort of intelligence. I was up there," he breathed swiftly, "and I saw it hanging there in the sky, quivering with heat and life."

"You are nervous, Stanton," said Vanderpool coolly. "Get a grip on yourself, man, and look at the thing reasonably. If that thing has intelligence," he added, "we will find some way to slay it."

"Slay it!" exclaimed Stanton. "How can you expect to slay a mad creation that can leap through s.p.a.ce, from world to world, like a wasp goes darting from flower to flower? How can you kill a thing which not only defies absolute zero but also the immeasurable heat which its friction with the atmosphere generated when it plunged toward the earth? How can you kill a thing that seems to have brains and nerves and bones and flesh of some strange substance that is harder and tougher than any earthly compound we have discovered?"

He stopped speaking for a moment. They listened to the voice that was broadcasting from the Worldwide Tower.
