<h4>A FIENDISH MACHINE</h4>
<p><span class = "firstword">A chill</span>
of fear gripped Tom and his companions as they blinked helplessly in the
glare! Had the enemy detected them the first moment they had set foot on
Balala Island? Had they walked blindly into a trap?</p>
<p>Gradually Tom's eyes and those of his friends adjusted to the
dazzling radiance. A door, blocking the tunnel just ahead, had slid open
and the light was pouring out of a room beyond.</p>
<p>"What happened?" Arv gasped.</p>
<p>Tom pointed downward to a pedallike plunger inserted in the tunnel
floor. "This must be a switch," he explained. "When I stepped on it
accidentally, it must have opened the door and flashed on the
lights."</p>
<p>Bud whistled. "Wow! Let's be thankful it wasn't a booby trap!"</p>
<p>"Maybe it is," murmured Hank grimly.</p>
<p><span class = "pagenum">167</span>
<SPAN name="page167"> </SPAN>
Steeling their nerves, and with every sense alert, the searchers
advanced into the secret room.</p>
<p>Tom suddenly gave a cry of amazement. "The earthquake machine!"</p>
<p>A huge hydraulic device, with massive steel bed and supporting
pillars, looking somewhat like the enormous body presses found in
automobile plants, stood embedded in a recess in one wall.</p>
<p>Tom rushed to the machine and examined it in fascination. A powerful
diesel generator stood nearby with banks of complicated electrical
equipment, amid a spider-web tangle of wiring. Tom assumed this gear was
for timing and synchronizing the shock waves. Evidently the whole setup
was operated from a single control panel in the wall, studded with knobs
and dials.</p>
<p>"What a job of design!" Tom exclaimed in awe. His eyes roved over
every detail of the equipment while he poked here and there with his
hands. He was getting the "feel" of the setup almost as much by touch
and handling as by his superb technical intuition. "Boy, I hate to
admire anything those Brungarian rebel scientists do, but this is really
masterful!"</p>
<p>"Yes? Well, don't go ga-ga over it," said Bud. "Let's do what we came
to do and scram out of here. This place makes me jumpy!"</p>
<p>Tom appeared oblivious. "It seems like vandalism to wreck such an
engineering achievement! Also, and this may sound strange to you," he
went
<span class = "pagenum">168</span>
<SPAN name="page168"> </SPAN>
on in a doubtful tone, "are we <i>really</i> justified in taking the law
into our own hands?"</p>
<p>"They're trying to wreck <i>our</i> setup, aren't they?" Bud
retorted. "Think of the destruction they've caused already! Do you want
to stand by and see Enterprises destroyed too?"</p>
<p>"Bud's right," Hank Sterling spoke up quietly. "Take a look at
this."</p>
<p>He beckoned them over to another corner of the cave and pointed to a
series of notations, crudely scrawled in white chalk on the cave wall.
Half hidden behind a clump of rock, they would have escaped casual
notice.</p>
<p>Tom read them and gave an angry gasp. A list of places and dates,
already checked off, showed the quakes that had occurred so far. The
last notation, not yet checked, said: SWIFT ENTERPRISES and was dated
five days ahead.</p>
<p>"Okay, that's all the convincing I need!" Tom said grimly.</p>
<p>He issued quick orders. Hank and Arv were to rush back to the <i>Sea
Hound</i>, get an underwater pump from the gear carried aboard, and
install it just off the beach. From there, they were to run a pipe line
up into the cave, using special plastic tubing which hooked together in
a jiffy.</p>
<p>"Cover the piping with sand and gravel, so it won't be noticed," Tom
added. "In the meantime, Bud and I will go to work on this setup
here."</p>
<p>"Aye-aye, skipper!" Hank and Arv responded.</p>
<p><span class = "pagenum">169</span>
<SPAN name="page169"> </SPAN>
As they hurried out through the tunnel, Tom and Bud set to work with the
tools they had brought along. The diesel was partly dismantled, sand
poured into its fuel feed, and the generator windings ripped out. The
boys then tore off and tangled all wiring leads to the electrical
equipment, took apart much of the equipment itself, and smashed the
control panel.</p>
<p>"Boy, if those Brungarian creeps get this setup working again,
they're <i>really</i> geniuses!" Bud said as he and Tom paused a
second.</p>
<p>"This is only the beginning, pal!" Tom said. "Let's tackle the
machine!"</p>
<p>The huge earthquake device was a far more difficult proposition to
disable. Its heavy structural parts had to be disassembled or pried
apart, one by one. Both boys were streaked with sweat as they
finished.</p>
<p>By this time, Hank and Arv had the piping installed halfway into the
tunnel. Spurred on as if by a sixth sense of danger, Tom told them to go
back to the beach and get the pump working while he and Bud connected
the few remaining pipe lengths into the machine room.</p>
<p>Minutes later, their job done, Tom and Bud rushed out to the mouth of
the cave and waved their flashlights. Soon the water could be heard
boiling through the pipeline. It gushed out with a roar, flooding the
machine room.</p>
<p>"Let's go!" Tom cried, yanking Bud's arm.</p>
<p><span class = "pagenum">170</span>
<SPAN name="page170"> </SPAN>
As they reached the beach and joined Hank and Arv, Tom's keen ears
picked up the drone of a plane somewhere in the darkness.</p>
<p>He gave a yell of alarm and pointed skyward. A ghostlike jet came
zooming into view, boring straight toward them. All four broke into a
mad dash for the seacopter.</p>
<p>They were halfway out on the reef when the plane leveled out of its
dive with an earsplitting whine.</p>
<p>"Hide!" Tom shouted, fearing a bomb might be dropped.</p>
<p class = "illustration">
<ANTIMG src = "images/pic170_171.jpg" width = "566" height = "276" alt = "(Tom and friends are attacked by a ray gun from an airplane)"></p>
<p><span class = "pagenum">171</span>
<SPAN name="page171"> </SPAN>
All leaped for cover among the rocks. At the same instant, a fiery beam
like a bolt of lightning shot from the plane. It seared the spot on the
reef they had just vacated!</p>
<p>"A ray gun!" Bud gasped.</p>
<p>The plane's speed had already carried it far past the island. Before
it could maneuver around for another pass, Tom and his companions were
on their feet, racing for the safety of the <i>Sea Hound</i>.</p>
<p>They were aboard and clamping shut the hatch lid as the jet made its
second pass. This time its fiery ray glanced harmlessly off the
seacopter's Tomasite sheathing. Seconds later, the <i>Sea Hound</i> had
darted off beyond reach into the ocean waters.</p>
<p><span class = "pagenum">172</span>
<SPAN name="page172"> </SPAN>
"Whew! We really broke all speed records that time!" Arv panted.</p>
<p>The others looked at him with wan but triumphant grins. Then they
began to speculate on what the beamlike bolt was, who was in the plane,
and if their enemy knew who Tom's group were.</p>
<p>Dawn was streaking the sky when the seacopter arrived at Fearing
Island. The adventurers flew back to Enterprises at once. Tom and Bud
snatched a few hours' sleep in the apartment adjoining Tom's
laboratory.</p>
<p>Later in the morning the whole group gathered in Tom's laboratory to
recount the raid to Mr. Swift and Harlan Ames. A bell signal from the
electronic brain brought them rushing to the decoder. Grim news awaited
them. The message said:</p>
<blockquote>
EXMAN TO SWIFTS. YOUR ENEMIES ARE NOW SURE I AM SPY. THEY PLAN TO
DESTROY ME.
</blockquote>
<p class = "space">
"No! It mustn't happen!" Tom cried in dismay. "Dad, I'll rescue him
myself!"</p>
<p>His words were greeted with shocked protests from the others.</p>
<p>"Don't be crazy!" Bud said. "You wouldn't have a chance!"</p>
<p>"It would be suicide!" Arv Hanson declared.</p>
<p>Chow grabbed his young boss by the arm. "Brand my cayenne pepper, before
I'd let you
<span class = "pagenum">173</span>
<SPAN name="page173"> </SPAN>
make a blame fool move like that, I'd rope an' hawg-tie you myself!"</p>
<p>Ames interjected the most convincing argument. "I know how you
feel, Tom," he said sympathetically, "but I'm positive the United States
government would never permit such a risky undertaking."</p>
<p>Tom was beside himself with anxiety. Not only had he worked and
struggled to make the space brain's visit a scientific success, but also
it was he who had thought of the scheme to use Exman as a spy. In Tom's
eyes, if the Brungarian rebels were to destroy the brain's body, it
would amount to murder! The young inventor knew that the destruction of
the "body" would not destroy the energy, but that it would be "lost" as
far as the earth was concerned.</p>
<p>Who knew, Tom asked himself, what priceless secrets the "brain" might
ultimately yield to earth's scientific researchers? If the Brungarians
were to succeed, this might deter the Swifts' space friends from ever
attempting another visit to our planet!</p>
<p>In despair, Tom turned to his father. "You know how much is at stake,
Dad!" he pleaded. "Isn't there something we can do?"</p>
<p>Mr. Swift had been silent, thoughtfully drumming his pencil on the
workbench. He looked up.</p>
<p>"Tom, I can think of only one thing," he said. "Perhaps our friends on
Planet X can help us.
<span class = "pagenum">174</span>
<SPAN name="page174"> </SPAN>
They said they would have no control over the energy until it was ready
to return home. But maybe we can get them to help us transfer the energy
back here—not by any means of earth transportation, but by some
extraterrestrial means known to their scientists."</p>
<p>Tom's eyes kindled with hope. "Dad, that's a terrific idea!" he
exclaimed. "Let's try!"</p>
<p>A message was quickly beamed out into space. Minutes went by. Then
the machine signaled a reply. It said:</p>
<blockquote>
WE WILL ATTEMPT RESCUE IF YOU WILL ARC A POWERFUL RADIO BEAM FROM POINT
OF ORIGINAL EARTH LANDING TO POINT WHERE ENERGY IS NOW.
</blockquote>
<p class = "space">
Moments later, a further message followed, giving technical instructions
on how to project the beam. It ended:</p>
<blockquote>
NOTIFY US WHEN SETUP IS READY.
</blockquote>
<p class = "space">
"Yahoo!" Chow whooped. "Brand my space guns, I reckon we'll get Ole
Think Box home safe after all!"</p>
<p>"He's not home yet, Chow," Tom cautioned, grinning but still tense
with worry. "Glad you said that, though. It reminds me that the first
job on our hands is to build a new think box for Exman!"</p>
<p>With hope alive, Tom turned icy calm and
<span class = "pagenum">175</span>
<SPAN name="page175"> </SPAN>
buckled down to the work at hand. Before beginning construction of a new
space robot, he contacted Exman via the electronic brain and asked him
for his exact location in Brungaria. The answer came in precise latitude
and longitude.</p>
<p>Next, Tom radioed instructions for the rescue plan. As soon as Exman
was notified that the invisible force from Planet X was ready to
transport his energy, he was to unlatch point five of his star head. He
would then be free to attach his energy to the rescue beam and be arced
back to the hillside spot near Enterprises, where Tom would have a new
robot body waiting.</p>
<p>Exman replied tersely:</p>
<blockquote>
MESSAGE UNDERSTOOD. WILL COMPLY.
</blockquote>
<p class = "space">
Tom snapped out orders. "Hank! Arv! Bud! And, Dad, we can sure use your
help too! Every hour may be precious! We must construct a replica of
Exman's robot container as fast as possible!"</p>
<p>Every resource of Swift Enterprises was convulsed into action. But
for all their scientific miracles, the staff could not perform magic.
The complicated robot device required hours of highly skilled
construction.</p>
<p>Darkness had fallen by the time the energy container was ready.
Meanwhile, a powerful transmitter and directional antenna had been set
up at the hillside spot. Extensive reports on the condition
<span class = "pagenum">176</span>
<SPAN name="page176"> </SPAN>
of the ionosphere poured into headquarters.</p>
<p>The Swifts and their small group of trusted associates trucked the
new robot and the electronic brain out to the site. Tom then signaled
his space friends that he was ready. They responded with the exact time
for the rescue attempt. Tom transmitted the information to Exman, who
replied:</p>
<blockquote>
DANGER NEAR. BRUNGARIAN SCIENTISTS READY TO DESTROY ME.
</blockquote>
<p class = "space">
"Great bellowin' buffaloes!" Chow gulped. "Please make it quick, Tom! We
got to save that space critter!"</p>
<p>Tom glanced at his illuminated watch dial. The countdown ticked by.
Suddenly his hand closed a switch, transmitting the rescue beam. More
moments passed as the Swifts and the watchers strained their eyes toward
the night sky.</p>
<p>"Here it comes!" Bud yelled suddenly.</p>
<p>A fiery bluish-white light had suddenly flamed into view. It grew
steadily larger. Tom poised the container and opened one point of the
star head.</p>
<p>Now the blue fireball was arcing down over the hillside, trailing its
orange-red comet tail. It hissed into the container and Tom snapped shut
the star head.</p>
<p>The next moment, the young inventor wavered and slumped
unconscious!</p>
