_The Tricks of the Trade_
He barked a command, and instantly Dick was seized by two of the
guards, one of whom--the one Dick had knocked down--took the occasion
to administer a buffeting in the process of overcoming him. For the
sight of the honored President of the United States--that kindly old
man straining his eyes to meet Dick's own--in the parti-colored garb
of red and yellow, and chained like a beast below the madman's throne,
again filled Dick with a fury beyond all control.
It was only when he had been half-stunned again by the vicious blows
of his captors, delivered with short truncheons of heavy wood, that at
length he desisted from his futile struggle.
With swimming eyes he looked upon the gathering about the throne,
which, again taking its cue from the madman, way roaring with laughter
at his antics. And again Dick's eyes encountered those of Fredegonde
Valmy.
The girl was not smiling. She was looking straight at him, and for a
moment it seemed to Dick as if he read some message in her eyes.
Only for an instant that idea flashed through his mind. He was in no
mood to receive messages. As he stood panting like a wild beast at
bay, suddenly a filmy substance was thrown over his head from behind.
Then, as his face emerged, and the rest of his body was swiftly
enveloped, he realized what was happening.
They had thrown over him one of the invisible garments. He could feel
the stuff about him, but he could no longer see his own body or limbs.
From his own ken, Dick Rennell had vanished utterly. Where his legs
and feet should have been, there was only the rug, with the burn from
the glass tube. He raised one arm and could not see arm or fingers.
In another moment invisible cords had been flung around him. Dick's
efforts to renew the struggle were quickly cut short. Trussed
helplessly, he could only stand glaring at the madman rocking with
laughter upon his tinsel throne. Beside him, similarly bound, stood
Luke Evans, but Dick was only conscious of the old man's presence by
reason of the short, rasping, emphatic curses that broke from his
lips.
* * * * *
The Emperor turned on his throne and beckoned to Von Kettler, who
approached with a deferential bow.
"Nobility, we charge you with the care of these two prisoners," he
addressed him. "Have the old one removed to the laboratory, and give
orders that he shall assist our chemists to the best of his power in
their analysis of the black gas. As for the other, take him up to the
central office, and show him how we deal with Yankees and all other
pigs. Show him everything, so that he may take back a correct account
of our irresistible powers when we dismiss him."
"Come!" barked one of the guards in Dick's ear.
Dick attempted no further resistance. Convinced of its futility, sick
and reeling from the blows he had received, he accompanied his captors
quietly. There was nothing more that he could do, either for President
Hargreaves or for old Luke, but he still imagined the possibility of
somehow warning the approaching fleet or the occupants of the
dirigible.
He was led along the passage, past the guards, and up the stairs
again. The top door opened upon vacancy; it closed, and vanished. Dick
felt the rugs beneath his feet, but he was to all appearances standing
on a square of bare earth in the middle of a prairie.
"Come!" barked the guard again, and Dick accompanied him, trailing his
silver chain. Behind came Von Kettler.
"Here are steps!" said the guard, after they had proceeded a short
distance.
Dick stumbled against the lowest step of an invisible flight. The
breeze was cut off, showing that they had entered a building.
Underneath was a large oval of bare ground. Dick found a handrail and
groped his way up around a spiral staircase, four flights of it.
"Here is a room!"
* * * * *
Dick saw that widening edge of door again. The room inside was
perfectly visible, though it seemed to be supported upon air. It was a
spheroid, of huge size, with a number of large windows set into the
walls, and it was filled with machinery. About a dozen workmen in
blue blouses were moving to and fro, attending to what appeared to be
a number of enormous dynamos, but there were other apparatus of whose
significance Dick was ignorant. The dynamos were whirring with intense
velocity, but not the slightest sound was audible.
Von Kettler stepped to a switch attached to a stanchion of white
metal, surmounted by a huge opaque glass dome, and threw it over.
Instantly the hum and whir of machinery became audible, the sound of
footsteps, the voices of the workmen, and the creak of boards beneath
their feet.
"You see, we have discovered the means of destroying sound waves as
well as shadows, and it was a much simpler feat," said Von Kettler
with a sneer. "Tell them that when you get back to Washington, Yankee
pig. Also you might be interested to know that most of your bombs fell
on camouflaged structures that we had erected with the intention of
deceiving you."
He gestured to Dick to precede him, and halted him at a plain round
iron pipe or rod that rose up through the floor and passed through the
roof. It was surrounded by a mesh of fine wire. Attached to it were
various gauges, with dials showing red and black numbers.
"This is perhaps our greatest achievement, swine," remarked Von
Kettler, affably. "You shall see its operations from above." He
pointed to a narrow spiral staircase rising at the far end of the
room. "It is the practical application of Einstein's gravitation and
electricity in field relation. It is by means of this, and the three
dynamos on the ground that we were able to neutralize your engines
last night and bring them down where we wanted them. You must be sure
to tell the Washington hogs about that."
* * * * *
He motioned to Dick to cross the room and ascend the spiral staircase.
Following him, he flung another switch similar to the first one, and
instantly all sound within the room was cut off.
They ascended the winding flight and emerged upon a floor or platform.
Dick felt it under his feet, but he could see nothing except the
ground, far beneath him. He seemed to be suspended in the void. He
stopped, groping, hesitating to advance. Von Kettler's jarring laugh
grated on his ears.
"Don't be afraid, swine," he jeered. "This place is enclosed. There is
a shadow-breaking device on every floor, which renders us complete
masters of camouflage."
A switch snapped. Dick found himself instantly in a rotunda, roofed
with glass, sections of which were raised to a height of three or four
feet from the wooden base, admitting a gentle breeze. Three or four
men were moving about in it, but these wore the black uniform with the
silver braid, and Von Kettler's manner was deferential as he addressed
them, jerking his hand contemptuously toward Dick. Grins of derision
and malice appeared on all the faces.
Save one, an elderly officer, apparently of high rank, who came
forward and raised his hand to the salute.
"Captain Rennell," he said, "we are at war with your nation, but we
are also, I hope, gentlemen." He turned to Von Kettler. "Is it
seemly," he asked, "that an officer of the American army should be
brought here in chains and cords?"
"Excellency, it is His Majesty's command," responded Von Kettler, with
a servile smirk that hardly concealed his elation. "Moreover, the
American is to witness the forthcoming destruction of the Yankee
fleet."
The elderly officer reddened, turned away without replying. Dick
looked about him.
* * * * *
There was less machinery in this room. The iron pillar that he had
seen came through the floor and terminated some five feet above it in
another of the opaque glass domes, filled with iridescent fire. About
it was a complicated arrangement of dials and gauges.
In the centre of the room was a sort of camera obscura. A large hood
projected above a flat table, and an officer was half-concealed
beneath it, apparently studying the table busily.
"Come, American, you shall see your navy on its way to destruction,"
said Von Kettler, beckoning Dick within the hood.
The officer stepped from the table, whose top was a sheet of silvered
glass, leaving Von Kettler and Dick in front of it. Dick looked. At
first he could see nothing but the vast stretch of sea; then he began
to make out tiny dots at the table's end, terminating in minute blurs
that were evidently smoke from the funnels.
"Your ships," said Von Kettler, smiling. "This is the dirigible." He
pointed to another dot that came into sight and disappeared almost
instantly. "They are a hundred and fifty miles away. Explain to your
friends in Washington that our super-telescopic sights are based upon
a refraction of light that overcomes the earth's curvature. It is
simple, but it happens not to have been worked out until my Master
commanded it."
Dick watched those tiny dots in fascination, mentally computing. At an
average speed of fifty knots an hour, the squadron's steaming rate,
they should be off the coast within three hours. The dirigible would
take two, if it went ahead to scout, as was almost certain.
* * * * *
Dick stepped back from beneath the hood and glanced about him. If only
his arms were not bound, he might do enough damage within a few
seconds to put the deadlier machinery out of commission, if only the
silvered mirror. He glanced about him. Von Kettler, interpreting his
thought, smiled coolly.
"You are helpless, my dear Yankee pig," he said. "But there is more
to see. Oblige me by accompanying me up to the top story."
He pointed to a ladder running up beside the iron pillar through an
opening in the roof, and Dick, with a shrug of the shoulders,
complied. He emerged upon a small platform, apparently protruding into
vacancy. Far underneath he saw the clearing, and two airplanes on the
tarmac, the aviators looking like beetles from that height. He looked
out to sea and saw no signs of the fleet.
"You have heard of St. Simeon Stylites, Yankee?" purred Von Kettler.
"The gentleman who spent forty years of his life upon a tall pillar,
in atonement for his sins? It is His Majesty's desire that you spend,
not forty years, but two or three hours up here, meditating upon his
grandeur, before returning to earth. It is also possible that you will
witness something of considerable interest. Look out to sea!"
Dick turned his head involuntarily. He heard Von Kettler's laugh,
heard the snap of a switch--then suddenly he was alone in the void.
At that snap of the switch, everything had vanished from view behind
him, the building, even the platform on which he stood. His feet
seemed to rest on nothing. Yet below him he could still see the
airplanes, and more being wheeled out.
* * * * *
A sense of extreme physical nausea overcame him. He reeled, then
managed to steady himself. He, too, was invisible to his own eyes.
Involuntarily he cried out. No sound came from his lips. He stood
there, invisible in an invisible, soundless void.
For what seemed an unending period he occupied himself with
endeavoring to obtain the sense of balance. Then, with a great effort,
he managed to loosen the cords that bound his right arm to his side. A
mighty wrench, and he had slipped them up above his elbow. His right
lower arm was free.
He extended it cautiously, and his hand encountered a railing.
Instantly he felt more at ease. He began moving slowly around in a
widening circle, and discovered that the platform was enclosed. The
further side was, however, open, and he began sliding forward, foot by
foot, to locate himself. Once his foot slipped over the edge, and he
drew back hastily. He felt on the other side, and discovered that he
was upon what seemed a plank walk, perhaps a hundred and fifty feet
above the ground, with no rail on either side, and some six feet wide.
Very cautiously he shuffled his way along it. It was solid enough,
although invisible, but more than once Dick walked perilously close to
one edge or the other. At length he went down on his hands and knees,
and proceeded, crawling, until his movements were arrested by what was
unmistakably a door.
The plank bridge, then, connected the top stories of two buildings,
but what the second was, there was no means of knowing. The door was
barred on the other side, and did not yield an iota to Dick's cautious
pressure. Dick felt the frame. Beyond was glass, reinforced with iron
on the outside, the latter metal forming a sort of lattice work.
Cautiously Dick began to crawl up the rounded dome.
* * * * *
Foot by foot he made his way, clinging to the iron bars, until he felt
that he had reached the point of the dome's maximum convexity. He
wedged his feet against a bar and rested. Only now was it brought home
to him that it would be impossible for him to find his way back to the
plank.
A long time must have passed, for, looking out to sea, he could see
the squadron now, minute points on the horizon, exuding smudges of
smoke. The dirigible was still invisible. The airplanes had either
left the tarmac or had been wrapped in the gas-impregnated cloth, for
both they and the aviators had vanished.
Suddenly Dick had an odd sensation that the iron was growing warm.
In another moment or two he had no doubt of it. The iron bar he
clutched was distinctly warm; it was growing hot. He shifted his grasp
to the adjacent bar and even in that moment the heat had increased
perceptibly.
Suddenly there came a vibration, a sense of movement. Dick was being
swung outward. The whole dome seemed to be dropping into space. He dug
his feet and fingers under the hot rods, and felt himself sliding over
on his back.
Back--back, till he was lying horizontally in space, and clutching
desperately at the iron bar, which was growing hotter every moment.
The sliding movement ceased. It was as if the whole upper section of
the glass dome had opened outward. But the heat of the bars was
becoming unbearable, and gusts of hot air seemed to be proceeding from
within.
Hot or not, Dick's only alternative was to work his way back to the
stable portion of the dome, or to frizzle until he dropped through
space.
Clinging desperately to the bars, he began working back, reaching from
bar to bar with his right hand and dragging his feet, with the
clanking chain attached, from bar to bar also.
* * * * *
How he gained the base of the dome he was never able afterward to
understand. The heat had grown intolerable; his hands were blistering.
Somehow he reached it. He rested a moment despite the heat. But to
find the plank walk was clearly impossible. In another minute he must
drop. Better that than to fry there like St. Lawrence on his griddle.
And then, just when he had resigned himself to that last drop, there
came an unexpected diversion. Almost beside him a window was hung
back. A man looked out. Dick saw one of the workmen in the blue
blouses, and, behind him, within the dome, what seemed like an empty
room.
Dick was slightly above the man. As his head and shoulders appeared,
he let himself go, landing squarely across his back. He slid down his
shoulders through the open window into the interior of the dome.
The man, flung against the frame of the window by the shock, uttered a
piercing cry. Before he could recover his stand, or take in what had
happened to him, Dick had gained his feet and leaped upon him. His
right hand closed upon his throat. He bore him to the floor and choked
him into insensibility.
