A Sudden Encounter

The map of the moon was not as complete as it could have been, either.

No particular interest had been taken in our satellite since the first

exploratory expeditions nearly fifty years before, when it had been

determined that the moon was of no value to Earthmen, either as an

outpost for colonization or a station for the production of power from

the sun's rays. Jack did the best he could, however, and the little dots

he placed on the map were close enough together to assure complete

vaporization of the solid material in less than the allotted time.

At the end of the second day out, by earth-time, the dead satellite

loomed immense, only five thousand miles ahead. Holden was in the pilot

house when Edwards began turning on the deceleration tubes.

"I flashed your message to the other ships," he said, as his quick

fingers touched the buttons which sent messages to the tube-room,

"telling them to stand by and land with us. I understand that the plan

is to use these ships to travel over the surface of the moon, making

landings in such positions that expeditions can be sent out in four

directions to plant cartridges. That will certainly give us plenty of

time, if nothing goes wrong."

"I don't see what could go wrong," replied Holden, "since that madman is

out of the way."

Eagerly he watched the dead, dust-covered surface approach, marveling at

the huge craters and precipitous peaks.

In two hours the five thousand miles had been reduced to less than that

many yards, and in a few more minutes the three great ships were

settling softly on the smooth surface of the plain at the foot of Mount

Julian.

Space suits were rapidly donned, the air-locks set in operation, and the

men hastily began unloading the first four charges of _hexoxen_ and

Europium. Holden called a meeting of the ship commanders in the pilot

room of the _San Francisco_.

"Commander Huges," he addressed the man in charge of the _Los Angeles_,

"you will proceed toward Mount Locke, and continue in that line until

you reach the spot marked on this chart, which is directly opposite our

present position. Rogers, you take the _Ganymede_, and go at an angle of

120 degrees to Huges' course, toward Mount Zoga. I will continue over

the Crater of Aristotle. We will keep in constant communication with

each other by means of the space phone. Time the charges so that they

will commence to react on the afternoon of the twenty-eighth, thus

giving a sufficient margin of time in case of delays due to parties

getting lost. That's all."

The _Ganymede_ and the _Los Angeles_ left almost immediately, while men

from the _San Francisco_ set out to plant the first charges. There were

four men to each cartridge, since it was necessary that they travel

fast.

Holden smiled as the lean figure of Professor Erickson, almost lost in

his space-suit, bounded away in great leaps at the head of his party. In

five hours they returned, having had no trouble at all. Edwards

manipulated the controls, and the ship rose quickly to an altitude of

about five thousand feet and headed for the rim of the Crater of

Aristotle, barely visible in the distance. As they neared the rim, they

rose higher and higher. The mammoth cliffs of black rock towered above

them, and the meters registered a height of five miles as they passed

through a crack in the cliffs and looked down on the level floor beneath

them.

Suddenly Holden, who had been inspecting the country from one of the bow

ports, uttered an exclamation of astonishment.

"A tiny ship is rising toward us from the floor of the crater, near the

cliffs!"

There it was, a speck rapidly growing larger, headed straight for them,

and gaining velocity with every foot it covered.

Edwards worked frantically with the controls, diving in a zig-zag path

toward the strange craft. Captain Linet rushed in, carrying one of the

light _hexoxen_ guns. Holden hurried to help him place it in a specially

designed aperture in the bow, while Erickson and the regular radio man

endeavored to establish communications with the intruder. A voice

suddenly spoke from their instrument.

"You will consider yourselves our captives. Land at once as close as

possible to the white spot you see at the base of the cliff. If you do

not obey instructions, we will ram you immediately."

"Don't reply for a moment," Holden commanded, focusing his glasses in

the direction indicated. As the powerful lenses brought out every detail

of the scene below, he paled visibly.

"What's the matter?" demanded Erickson.

"Matter enough," was the amazing reply. "We've run into a den of some

bandits. They must be the fiends who have been preying on the Earth-Mars

shipping!"

* * * * *

The tremendous speed of the dive had brought them so close that all

could see, without the aid of binoculars, the great skeletons of wrecked

ships piled up at the base of the precipice.

"Tell those rats to go to hell," snapped Holden, "and get in touch with

our own ships; use code and tell them to get here as quickly as

possible, prepared for a fight. Get near enough to this pirate ship to

open on it with the _hexoxen_ guns. Can you keep them from ramming us,

Edwards?"

"I think so, for a time, at least."

The enemy's craft was now only a few hundred yards away, and Holden

scrutinized it closely for any sign that might give a clue to the

original builders or present owners. Not over a hundred and fifty feet

in length, with no visible openings, it looked like a slightly fattened

steel needle. Its stern tubes were of the ordinary type; they glowed red

against the silvery background, as the enemy swooped and circled, trying

to get into position for a final, crushing blow.

"Every man in space suits," Holden ordered. "Good work, Linet," he

cried, as he saw a sudden pock-mark appear in the pirate's side, where

the devastating _hexoxen_ bullet had struck.

"They've certainly got thick plates," remarked the Captain, as another

direct hit failed to do more than scratch the metal. "Probably heavier

up in front, if they mean what they say about ramming. I'm going to

concentrate on the stern."

The dull red surface of the moon, the black walls of the crater, and the

twinkling stars of outer space mingled in a fantastic whirl as Edwards

skilfully kept the _San Francisco_ out of the enemy's reach, at the same

time giving Linet and the men in the observation compartment sufficient

opportunity to train their guns on vital spots. It was a hopeless game,

though, for the smaller ship was incredibly fast.

Erickson straightened up from his position behind the operator of the

space-phone. "We can't make any connections with either the _Ganymede_

or the _Los Angeles_. Probably these pirates have developed a shield

which, thrown around their victims, prevents any message from getting to

the outside."

That looked bad. Erickson switched the receiver back to the wave-length

of the enemy. A continual stream of taunts and threats came from the

loudspeaker.

"Why don't you surrender?" the gruff voice barked. "You haven't a chance

against us, but if you surrender you may be allowed to work with us, for

your own benefit as well as ours."

"Go to hell," the formerly meek Erickson roared into the transmitter,

surprised at his own rage.

Then finally, with a desperate dash, the tiny pirate ship darted in.

Edwards did his best to swerve away from the needle-point, but in vain.

There was a shattering crash; Holden felt himself hurled through the

air, but his heavy space-suit saved him from being crushed as he hit the

wall of the room. Edwards stayed with the controls, somehow, cursing

savagely.

"Only a glancing blow, but it smashed all the main stern tubes, and

evidently disabled the anti-gravitational shield transmitter. We're

going down."

Holden dashed to a port and glanced out. A welcome sight met his eyes.

The enemy, also injured, was heading for home as fast as his disabled

engines permitted.

"Those _hexoxen_ bombs must have weakened his plating, so that it sprang

when he rammed us," Edwards exclaimed when he saw what was happening.

Slowly the _San Francisco_ sank toward the red and black volcanic ash of

the crater floor. A hasty inspection revealed that Edwards had been

correct in his diagnosis of the trouble. Extensive repairs would be

necessary before they could proceed, but, fortunately, no one was

seriously hurt, and the main shell showed no signs of strains or leaks.

As soon as Edwards had brought them safely to rest on the ground, Holden

called a council of war.

"From the way these chaps fight, it's evident that they have no weapons,

other than the bow of their ship, and possibly some short-range ray

pistols, or the still more antiquated guns using some form of explosive

to expel metal bullets. As soon as the shadow of the cliff throws this

section of the crater into darkness, I'm going to do a little exploring,

and see if I can't find out where these rats hide, when they're not out

in space. Linet, you throw a line of pickets around the ship; Edwards,

get started on repairs, and Erickson, keep on trying to get in touch

with our companions."

* * * * *

Scarcely had he finished speaking when the light began to fade, and in a

few minutes it was pitch black. Refusing to take anyone along with him,

Holden crept out of the air-lock, and with an occasional glance at the

compass fastened inside his suit, always pointing toward the _San

Francisco_, he set out in the general direction of the wrecked space

ships he had seen piled along the base of the cliff. He made good time,

despite the weight of his suit and the poor footing afforded by the

loosely piled dust, and finally saw ahead of him the silvery gleam of a

ship's side. Afraid to use his light, he crept toward the bow of the

craft, past a huge hole, and reached the name-plate. Following the

deeply engraved characters, he slowly spelled out the name "G-L-O-R-,"

his heart gave a great thump. _Gloriana_, the Earth-Mars passenger

transport into which his own Jean had stepped so happily a year

previously!

A sudden hope flared up and then died down as he remembered the gaping

hole he had just passed. The cowards had probably attacked without

warning; the terrible cold of outer space had flooded through the

opening made by that sharp-pointed prow,--. He could not bear to carry

the image further; with a sob in his throat and murderous hatred in his

heart, he continued his search for the pirate stronghold.

Winding his way among other shattered ships, he came to the base of the

towering cliff, and turned to the right along it, finding his way by

constantly touching the hard rock with his gloved hand. Suddenly there

was a space where he could touch nothing, then the texture of the

material changed.

Carefully shielding the glow, he flashed a light on the wall for a

moment. It was metal, not rock! The pirates had walled in a cave with

plates from the captured transports; probably they were living within,

in all the luxury of their stolen wealth.

A few yards farther on his searching hand touched a seam in the metal,

still farther, another, evidently the air-lock through which the pirates

took their ship into the cave. Holden sat down to think. At that moment

the wall against which he leaned began to move slowly outward! A dim ray

of light came from the opening, which, as he turned to look, he saw to

be an air-lock. The inner door was closed, obviously someone was

expected to enter. He drew a deep breath, clasped his gun firmly in his

right hand, and plunged in.

As soon as he entered, the outer door closed; he heard valves click

open, air rushed into the chamber, and the inner door slowly opened,

revealing a long hall, dark and ominous.

Without removing the helmet of his space-suit, he started down the hall,

but had gone no more than a few steps before he felt a hand on his

sleeve, drawing him through a darkened doorway. The door closed, a light

flashed on, and before him stood, smiling and happy, his sweetheart,

Jean!

With a single movement he flung off his helmet and seized her in his

arms. For a short, delicious moment she clung to him, whispering those

words that lovers know so well. At last she said, "We haven't a minute

to lose, Jack. Let me tell you all I know about this place."

"But Jean, how did you get here? How does it happen that you had access

to the air-lock?"

"I was captured by these fiends, and am a prisoner, together with about

fifteen others, only five of them being men. All the rest were killed,

either when the pirates rammed the ships, or here, when they decided the

place was becoming crowded." Her face paled at the memory of the

horrible massacres, but she went bravely on.

"We have no space-suits, and the pirates, of whom there are perhaps

seventy-five, let us wander around pretty much as we please. We know of

practically everything that goes on. I happened to hear your name

mentioned in the phone room the other day, when a spy on your ship sent

a message. When the pirates brought their ship in, crippled by the

fight, I was sure that you were around somewhere. I have been watching

ever since, making use of a sound detector pieced together from some

scraps of material I picked up unnoticed.

"There aren't any guards because the gang is busy repairing the _Silver

Death_, as they call their ship, preparatory to finishing the job they

started today. Oh, Jack, you must go, now. They may be through at any

time. I don't know when I will see you again, if ever, but I couldn't

resist talking to you, touching you, just once more."

"One moment, dear. I have an idea. Is there any compartment, farther

back or lower down, where you could gather the prisoners together, and

be safe in case the outer wall was broken down?"

* * * * *

"Yes," she replied breathlessly, "one of the older, smaller caves is

still airtight, and while the gang is busy on the _Silver Death_ we

could go there and close the locks. What good would that do, though?

They are certain you can't get in here, or they wouldn't leave the place

unguarded. They have your ship surrounded by a wave-proof shield, so you

can't communicate with the others of your fleet, you know."

"I know that, but I think I can steal a leaf from their own book. Will

they all be working, say three hours from now?"

"I think so. Your guns did a great deal of damage, weakening the forward

structures of their craft."

"All right. Get your friends together in the old cave you mentioned,

seal it, and then wait till I come back."

Tenderly he kissed her good-bye, then hastened away, anxious to get his

work done before the shadow of the cliff again receded.

Thanking the fates for the good fortune that had saved Jean, and had led

her to the air-lock at the moment he was there, he stumbled over the

rocks and dust piles until halted by the picket line surrounding the

_San Francisco_. He called the men into the ship, and hastened to the

pilot room, where Edwards was testing the controls.

"Any luck?"

"Yes, a lot. Can you get the ship in shape to travel in three hours?"

"She's in pretty good shape now, although not capable of the trip back

to Earth."

Captain Linet entered at that moment, and with him Professor Erickson.

Holden recounted his adventures of the last hour and then set forth his

plan.

"The cave is walled up with thin plating from the ships the pirates have

brought in here. The entire gang is at work, repairing their own flier;

none of them, or at least only a few, are wearing space suits. I propose

to drive the bow of the _San Francisco_ into the wall of their cave,

previously weakening it by a few bursts from the _hexoxen_ guns!"

"It is possible," replied Edwards, "but it will probably put us out of

commission altogether."

"In any case," put in Erickson, "we will be rid of this damnable shield,

and can communicate with our companions."

It certainly was the only plan, for, as soon as the pirates had repaired

their ship, another unequal battle would be waged, with the result very

little in doubt.

All hands set to work completing repairs on the main stern tubes, the

only ones necessary to drive the _San Francisco_ forward. In less than

three hours, Edwards pronounced the work done to his satisfaction.

As the light began to creep in toward the base of the cliff, the huge

ship rose slightly off the ground, the tubes glowed red and, guided by a

powerful searchlight installed on the bow, Edwards pointed his craft

toward the gleaming metal patch that marked the position of the pirate

cave.

At short range, Holden, Linet, and Erickson opened with the three

_hexoxen_ guns. They saw the bursts take effect on the metal. Edwards

turned the power on full, and they felt the floor leaping under them.

Would the bow of the _San Francisco_ hold? Would they all be crushed to

death at the impact? Another moment would tell. Holden saw the metal

plates dead ahead, could distinguish the seams marking the air-lock.

He fired one final shot, and flung himself to the floor of the pilot

room, endeavoring to find some means of bracing himself for the shock.

Then it came! Torn from his position, he saw the plates buckling and

heaving about him. The lights went out. A great crash sounded in his

ears, and everything went black. In a moment he regained consciousness,

and staggered to his feet, bruised and dizzy. Thank God, his space suit

had not been harmed! A faint glow from the outside made things visible

and he saw that the shock had torn a huge piece out of the plating of

the pilot room.

A hand clutched his elbow, and through the phone in his space suit he

heard Linet's voice.

"Erickson and Edwards are knocked out. Let's see what we did to these

chaps here."

* * * * *

Rushing back through the corridor, they collected as many of the crew as

were able to move, flung open the heavy doors of the air-lock, and

scrambled down to the floor of the cave.

Here and there lay bodies, pirates caught unawares. Suddenly Holden saw

a blue flash. One of the mechanics clutched at his breast and fell, dead

in an instant.

"Some of these fellows are still alive. They're using ray pistols,"

Holden shouted into his suit phone.

Even as he spoke he heard the sound of running feet from the darkness in

the rear of the cave, where the bow of the _Silver Death_ was barely

visible in her cradle, and in a moment at least fifty figures, pirates

who had somehow escaped the fatal cold of space, clad in clumsy suits

and brandishing pistols, flung themselves desperately upon the smaller

party.

Blue flashes were everywhere as the battle commenced, but the only sound

was of struggling feet, with an occasional thud as a body hit the floor.

The pirates had been weakened by their long stay on the moon, and moved

slowly, but the surprise of their attack, and the superiority of numbers

had given them some advantage. It was man to man fighting, savage and

merciless.

Holden, with a neat dive, knocked the feet from under a huge fellow who

had trained a pistol on him, and they rolled over and over, each trying

desperately to gain a second's advantage. He heard a dull crash to one

side, as Captain Linet, jumping high into the air, landed with stunning

force on a bewildered assailant. Thinking of Jean, waiting for him in

some dim corner of the cave, he redoubled his efforts.

For a fraction of a second his pistol pointed toward his antagonist's

body, and that was enough. He pressed the release, and the deadly ray

shot into the body beneath him, dealing instant death. Freeing himself

from the cold grip, he ducked an empty pistol flung at him by a new

assailant. Again his finger bent, and another body dropped to join those

lying motionless on the floor.

A fast-moving shadow caught his eye. He saw one of the pirates detach

himself from a writhing group and head for the side of the cave. That

was the place where Jean had said she would be waiting!

Pausing only an instant to make sure that his pistol was still charged,

Holden sprang in pursuit of the fleeing form. He saw him stoop and pick

up a heavy bar from the floor. The coward was going to burst open the

chamber where the helpless captives waited! It was impossible to aim at

that speed, so Holden forced his flying feet to move still faster, and

foot by foot he drew closer to the man he pursued. Metal plates again

gleamed in front of him, and he saw the pirate raise the bar high over

his head, preparing for a blow which would crush the thin plates. The

tiniest hole would mean death to the captives, who had no means of

protecting themselves.

With one last desperate effort, Holden jumped, his Earth-trained muscles

carrying him high into the air, while his pistol stabbed the partial

darkness with vivid rays. Dodging and ducking, the pirate evaded the

fatal stabs, while his bar beat a loud tattoo against the metal. Holden

struck at him with his now useless pistol as he landed. The blow missed,

and, losing his balance, he staggered and fell, past his foe, who

quickly turned, raising his bar for a _coup de grace_ which never

landed. The familiar flash of a pistol once more illuminated the scene,

the bar dropped from dead hands, and Holden scrambled to his feet.

A voice was speaking through his suit phone, and he recognized it as

Erickson's. "I just came to, tumbled out of that hole in the pilot room,

saw the flash of your pistol, and here I am."

The old professor appeared, wobbling slightly, but still game. The

flashes toward the mouth of the cave had grown fewer. Leaving Erickson

to guard the compartment of the captives, Holden hurried back to the

fight. Even as he went, the flashes died out altogether, and he heard

Linet's hearty voice in the phone. "Holden, where are you? We've cleaned

out them all down here."

Light was now flooding in from outside, and bodies could be seen lying

thick on the floor, cold and stiff in death. Sadly Holden recognized

many of them as his own men. After a hasty conference with Linet, he

gathered together fifteen space suits, and with an escort helping to

carry them, he hurried back to Jean.

* * * * *

The door of the air-lock opened as his party approached. They went in,

heard the swish of air entering, and in a few minutes the inner door

swung wide. A happy crowd of men and women surrounded them, as they rid

themselves of their helmets. Holden felt Jean's arms around him, her

sweet lips once more on his. For a second they clung together, then

parted, for there was work to be done. The space suits were distributed

and, as he led the way back to the _San Francisco_, Jean told him

briefly the details of the long year of imprisonment.

"They gave us warning before they rammed us, as they wanted to save the

women, for a purpose you can guess. Fortunately, there were never enough

of us to go around, and these men, exiles from two planets, were always

quarreling among themselves, so we were quite safe. We just existed,

praying that some exploring expedition would find us, or that the

_Silver Death_ would meet a ship too strong for her to ram and, fleeing

here for refuge, be trailed."

Holden sighted Captain Linet hurrying toward them. In the light now

flooding the entire cavern, he could see lines of despair and

hopelessness written over the florid face.

"What's the matter?"

"Matter enough," came the ominous answer. "The space phone on our ship

is entirely disabled. We won't be able to get in touch with the

_Ganymede_ or the _Los Angeles_. In a few days, the _hexoxen_ charges

they plant will commence to go off, and that will be the end of us."

Holden stopped, stunned by the news. Fleeting visions of happiness with

Jean vanished into thin air. He would be destroyed by the chemical he

had invented, with which he had hoped to save the world.

"I thought we might get out in the _Silver Death_," continued the

captain, "but the entrance is entirely blocked by our own ship, and I'm

afraid it will never move again."

Then Jean's clear voice cut in. "How about the space phone on the

_Silver Death_? Won't it work?"

"Why, of course it will," laughed the captain, amused at his own

stupidity.

Stumbling and tripping in their haste, the three hurried through the

open air lock of the pirate craft, into the pilot room.

Holden feverishly set to work, whirling the strange dials, pushing this

button, then that. At last a faint roar sounded in the loud speaker.

Pressing his helmet against the transmitter, so that the vibrations

would carry his voice, he shouted, "_Ganymede_, _Los Angeles_, Holden

calling."

"What ho?" came a cheery voice, which he recognized as belonging to

Huges, commander of the _Los Angeles_.

Breathing a sigh of relief, he explained the situation. Busy days

followed. _Hexoxen_ and Europium from the _San Francisco_ were

transferred to the other ships, with as much of the treasure collected

by the pirates as could be loaded into the cramped quarters.

With Huges and Rogers assisting, Holden revised the schedule for

planting the charges.

"We simply haven't time," he explained, "to set the charges as close

together as I had planned. There's nothing to do but get all of them in

that we can, and then hope that conditions in the interior of the moon

will be of a nature to promote the action of the _hexoxen_."

The ships' crews understood only too well the importance and danger of

their work, and during the days that followed they toiled like a gang of

madmen. Parties raced each other over the rough surface of the dead

satellite, grimly determined that their efforts to save the world should

not be in vain. Even the men of the party which had been rescued,

weakened as they were by their long stay in the pirate cave, insisted on

giving what help they could.

Finally came the day when the first charges were set to go off. Holden

sat in the pilot room of the _Ganymede_, his eyes on the chronometer,

while Captain Linet swept the desolate plain with powerful binoculars

for the cloud of dust which would signal the return of the last party.

"Five minutes yet, Captain," Holden said in a low voice. "Tell the _Los

Angeles_ to pull out. The first charges are scarcely two hundred miles

from here, and I'm not certain how fast the reaction will travel."

Five minutes. Two minutes. The silver shape of the _Los Angeles_ was

already fading in the distance. Suddenly a sharp shock rocked the stony

bed on which the _Ganymede_ was resting. Simultaneously five figures

appeared, racing at full speed for the ship. Shock after shock tore at

the ground beneath their feet. Holden stood at the controls, waiting for

the signal that his five comrades were safely aboard. To his tensed

nerves it seemed hours before the welcome sound came to his ears, and

with a sigh of relief he opened the power into the stern tubes, and

laughed happily as the huge ship shot away from the heaving surface of

the dying moon.

Anxious seconds passed. From the height to which they had risen, a great

part of the moon was visible, and for the first time Holden realized the

full power of the chemical which his ingenuity had devised. Immense

tongues of flame ripped through the dust and rock of the satellite,

sending dense clouds of vapor bellowing out into space. Mighty mountains

disappeared in an instant.

The _Ganymede_ was traveling at full speed, and yet it seemed as though

at any moment the conflagration might reach out, consuming the space

ship in that all-engulfing reaction. Holden manipulated the controls

with flying fingers, seeking to get every available bit of speed from

the metal monster which was carrying its precious cargo of human beings

away from a terrible death.

Far ahead he could see the shape of the _Los Angeles_, now safely

outside the danger zone. Thin clouds of vapor floated around the

_Ganymede_, then suddenly cleared.

Captain Linet gave a shout of joy as he read the distance recorded on

the dials. "Jack, my boy, we're safe. We're outside the limit to which

the reaction can extend."

With the three ships playing their deadly beams on the moon, Holden

watched the immense craters, the towering mountains, and the desolate

plains of the moon slowly vaporize.

It was an awe-inspiring sight, as this dead world slowly melted into the

nothingness of space, as though a disease of matter were wasting it

inexorably away.

No doubt, on the earth, as the contours of the moon slowly blurred and

became indistinct, with the accumulation of vapor around its now ragged

rim, there must have been terror and consternation. And as the moon

slowly evaporated in the skies a virtual panic must have ensued among

the Earth's people.

The hand of a terrible fate, or the coming of the end of the world, must

have been shouted from city to city as the only explanation of this

apparent disaster in the heavens.

But the work had to go on....

For days, the _Ganymede_ and the _Los Angeles_ cruised through the thin

clouds, spreading between them the anti-gravitational shield, while the

sections of vapor, freed of their mutual attraction, drifted out into

uncharted space.

It was slow, dangerous work, cutting those sections off from the main

mass, and maintaining the proper position until they had floated off

into space. Occasional particles of rock, small but deadly, clattered

against the hard shell of the space ship. Fortunately, no fragments of

appreciable size were encountered; the _hexoxen_ had done its work

thoroughly. For eight days the powerful ray sliced and repelled. Under

its influence huge clouds of vapor, the ghostly remains of the calm

globe which had innocently threatened the earth, hurtled off into the

farthest reaches of space, there to sink at last into the substance of

some flaming star.

At last the work was finished, and the two ships, saviors of the Earth,

turned their bows toward home to carry to the awestruck people of Earth

the glad news that interplanetary commerce would be as free of pirates

thereafter as the Earth would be free of the disastrous quakes.

And Jack Holden, at last, faced with a light heart the honors that would

be his, knowing that he could now share them with the girl of his

dreams.
