"Hallo, what's that! I believe we're stopping - yes, we are - and we're beginning to rise, too. Look, dear, the clouds are coming down upon us - fast too! I wonder what sort of miracle that is. Ay, what's the matter, little woman?"
Zaidie's head had dropped heavily on his shoulder. A glance showed him that she had fainted. He could do nothing more in the conning-tower, so he picked her up and carried her towards the companion-way, past his three guests, who were standing in the middle of the upper deck round a table on which lay a large sheet of paper.
He took her below and laid her on her bed, and in a few minutes he had brought her to and told her that it was all right. Then he gave her a drink of brandy and water, and went hack on to the upper deck. As he reached the top of the stairway one of the astronomers came towards him with the sheet of paper in his hand, smiling gravely, and pointing to a sketch upon it.
He took the paper under one of the electric lights and looked at it. The sketch was a plan of the Jovian System. There were some signs written along one side, which he did not understand, but he divined that they were calculations. Still, there was no mistaking the diagram. There was a circle representing the huge bulk of Jupiter; there were four smaller circles at varying distances in a nearly straight line from it, and between the nearest of these and the planet was the figure of the Astronef, with an arrow pointing upwards.
"Ah, I see!" he said, forgetting for a moment that the other did not understand him, "That was the miracle! The four satellites came into line with us just as the pull of Jupiter was getting too much for our engines, and their combined pull just turned the scale. Well, thank God for that, sir, for in a few minutes more we should have been cinders!"
The astronomer smiled again as he took the paper back. Meanwhile the Astronef was rushing upward like a meteor through the clouds. In ten minutes the limits of the Jovian atmosphere were passed. Stars and gems and planets blazed out of the black vault of Space, and the great disc of the World that Is to Be once more covered the floor of Space beneath them - an ocean of cloud, covering continents of lava and seas of flame.
They passed Io and Europa, which changed from new to full moons as they sped by towards the Sun, and then the golden yellow crescent of Ganymede also began to fill out to the half andfull disc, and by the tenth hour of earth-time after they had risen from its surface, the Astronef was once more lying beside the gate of the Crystal City.
At midnight on the second night after their return, the ringed shape of Saturn, attended by his eight satellites, hung in the zenith magnificently inviting. The Astronef's engines had been replenished after the exhaustion of their struggle with the might of Jupiter. Zaidie and Lenox said farewell to their friends of the dying world. The doors of the air chamber closed. The signal tinkled in the engine-room, and a few moments later a blur of white lights on the brown background of the surrounding desert was all they could distinguish of the Crystal City under whose domes they had seen and learnt so much.

RAIDERS INVISIBLE
By D. W. Hall
Alone and unaided, Pilot Travers copes with the invisible foes who have struck down America's great engine of war.
The muffled, helmeted figure of a pilot climbed down the spider ladder, nestled into the foremost scout's cockpit and pressed the starting button. The motor spat out a wisp of smoke, then burst into its full-throated roar: the automatic clamp above loosened: the scout dropped plummet-like, bobbed to the flagship below, straightened out and zoomed six thousand feet up into the morning blue, where it hovered for a few moments like an eagle on taut wings. Lieutenant Christopher Travers, the pilot, glanced around.
Behind and below him was spread a magnificent panorama. Across the plate of scintillating glass that was the sea moved rows of toy ships, tipped by the gleaming, one-fifth-mile long shape of a dirigible, of whose three scout planes Chris's was the leader. As he watched, the second scout dropped from the plane rack beneath the dirigible's sleek underside and went streaking away, followed by the third, in response to the Admiral's order of: "Proceed ahead to locate the enemy's position."
A grin relaxed Chris Travers' tanned, boyish face. His narrowed gray eyes swept the horizon. Below it somewhere lay hidden the ranks of the Black Fleet, complete with its own destroyers, submarines, cruisers, battleships, aircraft carriers and the ZX-2, sister dirigible of the Blue Fleet's ZX-1. Chris spurted the scout ahead and murmured:
"This war game's goin' to be a big affair--the biggest yet!"
It was. The Atlantic Fleet of the United States Navy, termed "Blue" for convenience, had been assigned to guard the Panama Canal; the Pacific Fleet, "Black," to attack it. The cream of America's sea forces had been assembled for that week of March, 1935, all the way from crabby little destroyers to the two newly completed monarchs of the air, the twin dirigibles, fresh from the hangars at Akron, a thousand feet each in length and loaded with the latest offensive and defensive devices developed by Government laboratories.
The war game around the Canal was planned for more than practice, however. The eyes of the whole world were on that array of America's ocean might--the eyes of one foreign nation in particular. Washington knew of the policies of that nation, and wished to impress upon is the hopelessness of them. More than a game, this concentration of sea and air-borne fighting power was a gesture for the continued peace of the world--a gesture strong with the hint of steel.
Chris Travers was vaguely aware, through the rumors of the mess-room, of the double meaning of the game he was playing his part in, but this morning he didn't give a single thought. He was too wrapped up in his job of spotting the van of the Black Fleet, radio-telephoning latitude and longitude to the bridge of the Blue Fleet flagship, and getting home to his dirigible without being declared destroyed by one of the war game umpires.
Therefore, half an hour later, his heart thrilled as he glimpsed, wraith-like on the steely horizon, a wisp of smoke.
* * * * *
He catapulted forward, eyes steady on that hint of ships. The smoke grew to a cloud of black pouring from the funnels of a V-shaped squad of destroyers, rolling through the lazy swells of the Pacific waters. Behind them came the bulldogs, larger warships, hazy blurs in the distance.
Chris struck fist in palm to the tune of a gleeful chortle. He was first! He hauled the microphone from its cubby in the dashboard and spoke the code words. Latitude, longitude and steaming direction of the Black Fleet he gave rapidly, and the information knifed back to the bridge of the Blue Fleet flagship, a hundred miles behind, where a white-haired admiral said: "Ah! Good boy! Get those bombers up--pronto!"
Chris commanded a superb view of the ZX-2, whose gleaming shape, showering rays of sunlight, hung like a thing in a painting over the Black Fleet. He stared at the far-off dirigible, lost in admiration of her trim lines, pausing a minute before returning to his own ZX-1. At that distance, the mammoth craft seemed no more than four inches long, yet, through his telescopic sight, he could discern her markings, machine-gun batteries and the airplane rack along her belly plainly. One plane, he saw, was suspended from the rack; the others were scouting for the Blue Fleet, even as he had scouted for the Black. He wondered if something were wrong with the plane left behind. Somehow, it did not look quite familiar.
But, even as he watched, it dropped from the automatic rack, then straightened and soared dizzily up. And, from one of the airplane carriers' broad decks, he saw two pursuit craft begin to rise. He grinned. They'd seen him, were coming after him!
He gripped the stick, prepared to swerve around. He had already raised a spread-fingered hand for a derisive parting gesture, when suddenly he stiffened. The hand dropped as if paralyzed.
"Good Lord!" he gasped. "What--"
The mighty thousand-foot dirigible ZX-2, pride of the Navy and all America, had wobbled drunkenly in her path. She stuck her nose down, and then her whole vast frame shivered like a wind-whipped leaf as the dull roar of an explosion rolled over the
sea. A huge sliver of hide was stripped from her as if by magic, revealing the skeleton of girders inside--revealing a tongue of crimson that licked out and welled into a hell of flame.
Chris's blood froze. He watched the ZX-2 wallow in her death throes, writhe in the fiery doom that had struck her in seconds, that was devouring her with awful rapidity while thousands of men, blanched and trembling, gazed on helplessly. He saw her plunge, a blazing inferno, into the sea beneath....
There were old pals on her--buddies, gone in a flash of time!
This wasn't a war game. This was tragedy, stark before his eyes.
* * * * *
The Black Fleet forgot its mimic battle. Radio telephone messages winged over the horizon to the approaching Blue Fleet. The Black dreadnoughts hove to; launches with ashen-faced men in white manning them dropped overboard; a dozen destroyers rolled in the swells around a crumbled, charred egg-shell that but minutes before had been an omnipotent giant of the sky.
Chris Travers, aloft in sunlight suddenly bereft of its beauty, jammed the stick of the scout full over. He could do nothing, he knew. He could only return to the ZX-1 and tell the story of its sister as he had seen it.
But why, he wondered as he flew almost blindly, had the ZX-2 so quickly flamed to oblivion? The helium of its inner bags bad been uninflammable, as had the heavy oil of its fuel tanks; the ten engines were Diesels, and hence without the ordinary ignition system and gasoline. Safety devices by the score bad been installed on board; nothing had been overlooked. And the weather, perfect.
It was uncanny. It seemed totally unexplainable.
Swarms of planes droned between sea and sky, all speeding in the one direction, west, to where the crumpled remnants of a dirigible were slipping quickly beneath the billows, beyond the sight of man. Planes of war game umpires, of officials, of newspaper correspondents and photographers. And soon a spectral, gleaming wisp of silver nosed out of the east, and the lone scout flying east dropped in altitude to meet its mother.
Mechanically, his mind elsewhere, Chris shoved the button which reared the automatic clamp behind the cockpit in preparation for affixing the scout to the plane rack beneath the ZX-1. The dirigible, far in advance of the Blue Fleet, was roaring along at its full one hundred and fifty to hover over the grave of its sister. Chris eyed its course and changed his. To jockey into the rack, he had to pass the dirigible and come up underneath from its rear.
* * * * *
The air giant roared closer. As the distance between then loosened, Chris's brow wrinkled and he swore softly in puzzlement.
"Now, just what's wrong with them?" he exclaimed, "The darned zep isn't flying straight! She's wobbling in her course!"
It was hardly apparent, but true. Ever so slightly, the snub nose of the ZX-1 was swaying from side to side as it sped through the air; ever so slightly, her massive stern directional-rudders were wavering.
She was less than a mile away now. At that time, there were no other planes in sight; none flying in that vicinity save Chris's. He glued his eyes to the telescopic sight. A moment later, sheer horror swept his face.
"Good God!"
The scout leaped as its throttle rammed down. The gleaming, thousand-foot shell of the ZX-1 roared by it at equal altitude, making it a puny fly-speck in the sky. But the fly-speck was faster. It turned in a screaming bank; it straightened; it lunged back after the swaying, retreating mammoth like a whippet, lower, now, than its quarry. It maneuvered expertly as it gained, for one of the best pilots of the service was at its controls, and there were deep lines graven in his face, lines of anguish and intolerable suspense.
Through the telescopic sight, Chris had not seen a single white-clad figure standing beside the glass ports of the dirigible's control car. But he had seen, slung from the rack along her belly, a single plane--the same rather peculiar-looking plane he had seen hanging beneath the rack of the ZX-2 a few minutes before she had gone down in flames!
And in that plane, he knew surely, was the answer to the mystery.
* * * * *
Speed cut to just a trifle more than the dirigible's. Chris passed a few feet underneath the huge expanse of her lower directional rudder. From so close, its uncontrolled wavering was terrifying.
His faculties were concentrated on the task of sliding the scout's clamp into the groove of the plane rack, but he was also surveying the lone airplane hanging from it. A powerful machine, painted in Navy colors, a peculiar knob on the upper side of each half of the top wing gave it its unfamiliar appearance. Its pilot was obviously aboard the dirigible, working....
Closer and closer the scout crept, quarter-way now along from the stern of the massive bulk that loomed above it, and within fifty feet of the third clamp in the rack. Touchy work, maneuvering into it, with the ZX-1 yawing as she was, and the need for haste desperate. Chris's hands were glued to the stick: his nerves were as tight as violin strings. Then, when only ten feet from the rack clamp, he gave a startled jump of uncomprehending amazement.
The propeller of the mysterious plane ahead had roared over. Its clamp had left the rack; it had dropped down in a perfectly controlled dive and flattened out as if a master pilot were at its controls.
But the plane's cockpit was still empty, Chris could see; nor had he seen any figure pass down the ladder from the dirigible into it!
Devoid of all emotion save bewilderment, he sat stupidly in the scout. A moment later, so well had he aimed it, its clamp nestled snugly into the groove of the rack, and the regular automatic action took place. A tiny door slid open directly above in the dirigible's hull: a thin ladder craned down--and Chris's nostrils caught a faint whiff of something that cleared his mind of its confusion instantly.
Just a whiff, but it registered. Gas, with an odor resembling carbon monoxide.
He stared up. Over the edge of the automatic trap-door above, a white, contorted face was hanging. The dirigible swung; white-clad shoulders and body slumped into view. Then, with a rush, the body slipped through, jarred against the connecting ladder, slithered off and went twisting and turning into the gulf below.
"God!"
Gassed! How, by what, Chris had no idea. A moment before he had been about to follow the uncannily piloted plane; but now his duty was plain. He knew with awful certainty that in minutes, seconds perhaps, the giant ZX-1 was scheduled to roar into flames like its sister and plunge into the Pacific.
He jerked out a gas mask. He was fitting it on with one hand as, with the other, he hauled himself up the spider ladder into the hull of the thundering, yawing dirigible.
He did not see, hovering a few hundred yards behind the ZX-1, the mystery plane; he did not see it now begin to approach the rack once more.
* * * * *
The crew of that dirigible of death, Chris discovered, had not had a chance. White-clad bodies lay sprawled throughout the cabin which contained the mechanism of the plane rack, stricken down silently at their posts. There was no life, no sound save the booming of the motors and the whip of the wind screaming past the uncontrolled air titan.
But he did not pause there. He did not know what he was grappling with--it seemed black magic--but he darted to a ladder which angled up from the lowermost entrance cabin to the cat-walk that stretched from the nose to the stern of the ship. If any infernal contrivance had been planted aboard, it would be in the most vital spot.
Heart pumping from the artificial air he was breathing and from the consciousness that each second might well be his last, he sprinted along the interior gangway. Above was the vasty gloom of the gas bags and the interweaving latticework of the supporting girders; the drum of power-car motors and the strained creakings of cables and supports echoed weirdly throughout. Outside was the sun and the sea and the clean air, but this realm of mammoth shapes and dimness seemed apart from the world. Once he stumbled against something soft and yielding--a body flung down there in death, fingers at its throat. And there were other white-clad figures, grimly marking off the length of the
cat-walk....
Chris's nerves were raw and his face sopping with sweat beneath its mask when suddenly he stopped at sight of something that lay on the cat-walk, with the main fuel tanks on the girders just above it and the entrance to the control car just below.
* * * * *
It was a black box, perhaps two feet square and a foot in depth, made of dull metal that did not reflect the rays of the light bulb placed at the head of the ladder leading down in the control car. There were three curious little dials on its face, and the trembling finger of each one was mounting.
It had been strategically placed. An explosion at that point would rip open the fuel tanks, split the largest gas bag, wreak havoc on an intricate cluster of main girders, and destroy the control car with its mechanism.
"No wonder the ZX-2 crashed!" Chris muttered.
Then his hands swept down. The next instant he was hugging the thing tight to his chest and stumbling down into the control car, hearing only a high-pitched, impatient whine that was coming from the box as the fingers of its dials crept slowly upward.
The ZX-1 was wavering wildly as her rudders flopped from side to side, and with every swing the bodies that lay in her control car, strangled by gas, stirred slightly. The gray-haired commander was stretched there, one arm limply rolling as his ship, which had gone so suddenly from him, rolled. Subordinate officers were tumbled around him. Death rode the control car.
But down to it and through it now came one who was alive, a figure made grotesque by the mask it wore and the pack of the parachute strapped to it, who threaded past the littered bodies, an ever-rising whine wailing from the box clasped in his arms.
With a leap, he was at one of the car's port-holes, fingers fumbling at the heavy bolts. The seconds seemed eternal, and the box's whine had become a shattering, sinister scream when at last the bolts loosened. The round pane of glass teetered back, swung open--and the masked man slung his metal burden out, out from the ZX-1 into the gulf between sea and sky.
