<h2><SPAN name="Introduction_to" id="Introduction_to"></SPAN>Introduction to<br/> <i>ULLER UPRISING</i></h2>
<h3>by John F. Carr</h3>
<p>With the publication of this novel, <i>Uller Uprising</i>, all of H. Beam
Piper's previously published science fiction is now available in Ace
editions. <i>Uller Uprising</i> was first published in 1952 in a Twayne
Science Fiction Triplet—a hardbound collection of three thematically
connected novels. (The other two were Judith Merril's <i>Daughters of
Earth</i> and Fletcher Pratt's <i>The Long View</i>.) A year later it appeared
in the February and March issues of <i>Space Science Fiction</i>, edited by
Lester Del Rey.</p>
<p>The magazine version, which was abridged by about a third, was
believed by many bibliographers to be the only version—and as a
novella it was too short for book publication. The Twayne version had
a small print run and is so scarce that few people have seen it. Those
bibliographers who knew of its existence assumed that both versions of
<i>Uller</i> were the same. It was through a telephone conversation with
Charles N. Brown, publisher of <i>Locus</i> and correspondent with Piper,
that I learned about the Twayne edition and its greater length. Brown
allowed me to photocopy his original, for which we owe him a debt of
thanks; because the Twayne version is not only novel length, but far
better than the shorter one that appeared in <i>Space Science Fiction</i>.<span class="pagenum"><SPAN name="Page_vi" id="Page_vi"></SPAN></span></p>
<p>Probably the most surprising and interesting thing about the Twayne
edition is the essay that forms the introduction to that volume, and
is reprinted here. The essay is by Dr. John D. Clark, an eminent
scientist of the forties and fifties and one of the discoverers of
sulfa, the first "miracle drug." It describes in great detail the
planetary system of the star Beta Hydri, and gives the names of those
planets: Uller and Niflheim. A publisher's note states that Clark's
essay was written first, and given to the contributors as background
material for a novel they would then write.</p>
<p>The fans of H. Beam Piper seem to owe a great debt to Dr. Clark.
<i>Uller Uprising</i> became the foundation of Piper's monumental
Terro-Human Future History; the first story where we encounter the
Terran Federation. In it we learn about Odin, the planet that will one
day be the capital of the First Galactic Empire; and humble Niflheim,
which in more decadent times will become a common expletive, a word
meaning hell. This is also where Piper introduced and explained the
Atomic Era dating system (A.E.). <i>Uller Uprising</i> is set in the early
years of the Terran Federation's expansion and exploration, an epoch
of great vitality. In "The Edge of the Knife" Piper compares this time
of discovery to the Spanish conquest of the Americas. This feeling of
vigor and unlimited possibilities runs through all the early
Federation stories: <i>Uller Uprising</i>, "Omnilingual," "Naudsonce,"
"When in the Course—," and, to a lesser degree, in the late
Federation novels, <i>Little Fuzzy</i>, <i>Fuzzy Sapiens</i>, and <i>Fuzzies and
Other People</i>. (See <i>Federation</i> by H. Beam Piper for a good overview
of this period.)</p>
<p>In these stories we see Terro-Humans at their best and at their worst:
Individual heroism and bravery in<span class="pagenum"><SPAN name="Page_vii" id="Page_vii"></SPAN></span> the face of grave danger in <i>Uller
Uprising</i>; Federation law and justice in <i>Little Fuzzy</i> and its
sequels; and, in "Omnilingual" and "Naudsonce," the spirit of science
and rational inquiry. Yet we also see colonial exploitation and
subjugation in <i>Uller Uprising</i> and "Oomphel in the Sky," the greed
and corruption of Chartered land companies in <i>Little Fuzzy</i>, and
political corruption in <i>Four-Day Planet</i>. These stories are about a
living Terro-Human culture, not a utopia.</p>
<p>It was Piper's attention to historical realism and his use of actual
historical models that have helped his work to pass the test of time
and have led to his becoming the favorite of a new generation of
readers more than twenty-five years after his death.</p>
<p><i>Uller Uprising</i> is the story of a confrontation between a human
overlord and alien servants, with an ironic twist at the end. Like
most of Piper's best work, <i>Uller Uprising</i> is modeled after an actual
event in human history; in this case the Sepoy Mutiny (a Bengal
uprising in British-held India brought about when rumors were spread
to native soldiers that cartridges being issued by the British were
coated with animal fat. The rebellion quickly spread throughout India
and led to the massacre of the British Colony at Cawnpore.). Piper's
novel is not a mere retelling of the Indian Mutiny, but rather an
analysis of an historical event applied to a similar situation in the
far future.</p>
<hr style='width: 45%;' />
<p>Like many philosophers and social theorists before him, Piper
attempted to chart the progress of human-kind; unlike most, however,
he did not envision or try to create a system of ethics that would end
all of humanity's problems. The best he could offer was his<span class="pagenum"><SPAN name="Page_viii" id="Page_viii"></SPAN></span> model of
the self-reliant man: The man who "actually knows what has to be done
and how to do it, and he's going to go right ahead and do it, without
holding a dozen conferences and round-table discussions and giving
everybody a fair and equal chance to foul things up for him."</p>
<p>Piper brought his own ideas and judgments about society and history
into all of his work, but they appear most clearly in his Terro-Human
Future History. While not everyone will agree with Piper's theories
they give his work a bite that most popular fiction lacks. One cannot
read Piper complacently. And one can often find a wry insight
sandwiched in between the blood and thunder.</p>
<p>Other future histories may span more centuries or better illuminate
the highlights of several decades, but until a rival is created with
more historical depth and attention to detail, H. Beam Piper's
Terro-Human Future History will stand as the Bayeux Tapestry of
science fiction histories.</p>
<p>In many ways—certainly during his lifetime—Piper was the most
underrated of the John W. Campbell's "Astounding" writers. He was
probably also the most Campbellian; his <i>self-reliant man</i> is almost a
mirror image of Campbell's "Citizen."</p>
<p>Piper died a bitter man, a failure in his own mind; shortly before his
death he believed he could no longer earn a living as a writer without
charity from his friends or the state.</p>
<p>Now he's the cornerstone of Ace Books. Had he lived long enough to
finish another half dozen books, he would have been among the sf
greats of the sixties....</p>
<p>But maybe he does know, after all. Jerry Pournelle,<span class="pagenum"><SPAN name="Page_ix" id="Page_ix"></SPAN></span> who was very much
influenced by Piper and in many ways considers himself Beam's
spiritual descendant—and incidently was John W. Campbell's last major
<i>discovery</i>—has said that sometimes, when he's gotten down a
particularly good line, he can hear the "old man" chuckle and whisper,
<i>atta boy</i>.</p>

<h2><SPAN name="Introduction" id="Introduction"></SPAN>Introduction</h2>
<h2>Dr. John D. Clark</h2>
<h3>THE SILICONE WORLD</h3>
<h3>1. THE STAR AND ITS MOST IMPORTANT PLANET</h3>
<p>The planet is named Uller (it seems that when interstellar travel was
developed, the names of Greek Gods had been used up, so those of Norse
gods were used). It is the second planet of the star Beta Hydri, right
angle 0:23, declension -77:32, G-0 (solar) type star, of approximately
the same size as Sol; distance from Earth, 21 light years.</p>
<p>Uller revolves around it in a nearly circular orbit, at a distance of
100,000,000 miles, making it a little colder than Earth. A year is of
the approximate length of that on Earth. A day lasts 26 hours.</p>
<p>The axis of Uller is in the same plane as the orbit, so that at a
certain time of the year the north pole is pointed directly at the
sun, while at the opposite end of the orbit it points directly away.
The result is highly exaggerated seasons. At the poles the temperature
runs from 120°C to a low of -80°C. At the equator it remains not far
from 10°C all year round. Strong winds blow during the summer and
winter, from the hot to the cold pole; few winds during the spring and
fall.<span class="pagenum"><SPAN name="Page_xii" id="Page_xii"></SPAN></span> The appearance of the poles varies during the year from baked
deserts to glaciers covered with solid CO<sub>2</sub>. Free water exists in
the equatorial regions all year round.</p>
<h3>2. SOLAR MOVEMENT AS SEEN FROM ULLER</h3>
<p>As seen from the north pole—no sun is visible on Jan. 1. On April 1,
it bisects the horizon all day, swinging completely around. April 1 to
July 1, it continues swinging around, gradually rising in the sky, the
spiral converging to its center at the zenith, which it reaches July
1. From July 1 to October 1 the spiral starts again, spreading out
from the center until on October 1 it bisects the horizon again. On
October 1 night arrives to stay until April 1.</p>
<p>At the equator, the sun is visible bisecting the southern horizon for
all 26 hours of the day on January 1. From January 1 to April 1, the
sun starts to dip below the horizon at night, to rise higher above it
during the day. During all this time it rises and sets at the same
hours, but rises in the southeast and sets in the southwest. At noon
it is higher each day in the southern sky until April 1, when it rises
due east, passes through the zenith and sets due west. From April 1 to
July 1, its noon position drops down to the north, until on July 1, it
is visible all day, bisected by the northern horizon.</p>
<h3>3. CHEMISTRY AND GEOLOGY OF ULLER</h3>
<p>Calcium and chlorine are rarer than on earth, sodium is somewhat
commoner. As a result of the shortage of calcium there is a higher
ration of silicates to<span class="pagenum"><SPAN name="Page_xiii" id="Page_xiii"></SPAN></span> carbonates than exists on earth. The water is
slightly alkaline and resembles a very dilute solution of sodium
silicate (water glass). It would have a pH of 8.5 and tastes slightly
soapy. Also, when it dries out it leaves a sticky, and then a glassy,
crackly film. Rocks look fairly earthlike, but the absence or scarcity
of anything like limestone is noticeable. Practically all the
sedimentary rocks are of the sandstone type.</p>
<p>All rivers are seasonal, running from the polar regions to the central
seas in the spring only, or until the polar cap is completely dried
out.</p>
<h3>4. ANIMAL LIFE</h3>
<p>As on Earth life arose in the primitive waters and with a carbon base,
but because of the abundance of silicone, there was a strong tendency
for the microscopic organisms to develop silicate exoskeletons, like
diatoms. The present invertebrate animal life of the planet is of this
type and is confined to the equatorial seas. They run from amoeba-like
objects to things like crayfish, with silicate skeletons. Later, some
species of them started taking silicone into their soft tissues, and
eventually their carbon-chain compounds were converted to silicone
type chains, from</p>
<div class="center"><ANTIMG src="images/image_02.jpg" alt="Table_01" width-obs="600" height-obs="107" /></div>
<p>with organic radicals on the side links. These organisms were a
transitional type, with silicone tissues and water body fluids,
resembling the earthly amphibians, and are now practically extinct.
There are a few species, something like segmented worms, still to be
seen in the backwaters of the central seas.<span class="pagenum"><SPAN name="Page_xiv" id="Page_xiv"></SPAN></span></p>
<p>A further development occurred when the silicone chain animals began
to get short-chain silicones into their circulatory systems, held in
solution by OH or NH<sub>2</sub> groups on the ends and branches of the
chains. The proportion of these compounds gradually increased until
the water was a minor and then a missing constituent. The larger
mobile species were, then, practically anhydrous. Their blood consists
of short-chain silicones, with quartz reinforcing for the soft parts
and their armor, teeth, etc., of pure amorphous quartz (opal). Most of
these parts are of the milky variety, variously tinted with metallic
impurities, as are the varieties of sapphires.</p>
<p>These pure silicone animals, due to their practical indestructibility,
annihilated all but the smaller of the carbon animals, and drove the
compromise types into odd corners as relics. They developed into a
fish-like animal with a very large swim-bladder to compensate for the
rather higher density of the silicone tissues, and from these fish the
land animals developed. Due to their high density and resulting high
weight, they tend to be low on the ground, rather reptilian in look.
Three pairs of legs are usual in order to distribute the heavy load.
There is no sharp dividing line between the quartz armor and the
silicone tissue. One merges into the other.</p>
<p>The dominant pure silicone animals only could become mobile and
venture far from the temperate equatorial regions of Uller, since they
neither froze nor stiffened with cold, nor became incapacitated by
heat. Note that all animal life is cold-blooded, with a negligible
difference between body and ambient temperatures. Since the animals
are silicones, they don't get sluggish like cold snakes.<span class="pagenum"><SPAN name="Page_xv" id="Page_xv"></SPAN></span></p>
<h3>5. PLANT LIFE</h3>
<p>The plants are of the carbon-metabolism, silicate-shell type, like the
primitive animals. They spread out from the equator as far as they
could go before the baking polar summers killed them. They have normal
seasonal growth in the temperate zones and remain dormant and frozen
in the winter. At the poles there is no vegetation, not because of the
cold winter, but because of the hot summer. The winter winds
frequently blow over dead trees and roll them as far as the equatorial
seas. Other dead vegetation, because of the highly silicious water,
always gets petrified unless it is eaten first. What with the
quartz-speckled hides of the living vegetation and the solid quartz of
the dead, a forest is spectacular.</p>
<p>The silicone animals live on the plants. They chew them up, dehydrate
them, and convert their silicious outer bark and carbonaceous
interiors into silicones for themselves. When silicone tissue is
metabolized, the carbon and hydrogen go to CO<sub>2</sub> and H<sub>2</sub>O, which
are breathed out, while the silicone goes into SiO<sub>2</sub>, which is
deposited as more teeth and armor. (Compare the terrestrial octopus,
which makes armor-plating out of calcium urate instead of excreting
urea or uric acid.) The animals can, of course, eat each other too, or
make a meal of the small carbonaceous animals of the equatorial seas.</p>
<p>Further note that the animals cannot digest plants when they are cold.
They can eat them and store them, but the disposal of the solid water
and CO<sub>2</sub> is too difficult a problem. When they warm up, the water in
the plants melts and can be disposed of, and things are simpler.<span class="pagenum"><SPAN name="Page_xvi" id="Page_xvi"></SPAN></span></p>
<hr style="width: 65%;" />
<h2>II</h2>
<h2>THE FLUORINE PLANET</h2>
<h3>1. THE STAR AND PLANET</h3>
<p>The planet named Niflheim is the fourth planet of Nu Puppis, right
angle 6:36, declension -43:09; B8 type star, blue-white and hot, 148
light years distant from Earth, which will require a speed in excess
of light to reach it.</p>
<p>Niflheim is 462,000,000 miles from its primary, a little less than the
distance of Jupiter from our sun. It thus does not receive too great a
total amount of energy, but what it does receive is of high potential,
a large fraction of it being in the ultra-violet and higher
frequencies. (Watch out for really super-special sunburn, etc., on
unwarned personnel.)</p>
<p>The gravity of Niflheim is approximately 1 g, the atmospheric pressure
approximately 1 atmosphere, and the average ambient temperature
about -60°C; -76°F.</p>
<h3>2. ATMOSPHERE</h3>
<p>The oxidizer in the atmosphere is free fluorine (F<sub>2</sub>) in a rather
low concentration, about 4 or 5 percent. With it appears a mad
collection of gases. There are a few inert diluents, such as N<sub>2</sub> (nitrogen), argon, helium, neon, etc., but the major fraction consists
of CF<sub>4</sub> (carbon tetrafluoride), BF<sub>3</sub> (boron trifluoride), SiF<sub>4</sub>
(silicon tetrafluoride), PF<sub>5</sub> (phosphorous pentafluoride), SF<sub>6</sub> (sulphur hexafluoride) and probably others. In other words, the
fluorides of all the non-metals that can form fluorides. The
phosphorous pentafluoride rains out when the weather gets cold. There<span class="pagenum"><SPAN name="Page_xvii" id="Page_xvii"></SPAN></span>
is also free oxygen, but no chlorine. That would be liquid except in
very hot weather. It sometimes appears combined with fluorine in
chlorine trifluoride. The atmosphere has a slight yellowish tinge.</p>
<h3>3. SOIL AND GEOLOGY</h3>
<p>Above the metallic core of the planet, the lithosphere consists
exclusively of fluorides of the metals. There are no oxides, sulfides,
silicates or chlorides. There are small deposits of such things as
bromine trifluoride, but these have no great importance. Since
fluorides are weak mechanically, the terrain is flattish. Nothing
tough like granite to build mountains out of. Since the fluoride ion
is colorless, the color of the soil depends upon the predominant metal
in the region. As most of the light metals also have colorless ions,
the colored rocks are rather rare.</p>
<h3>4. THE WATERS UNDER THE EARTH</h3>
<p>They consist of liquid hydrofluoric acid (HF). It melts at -83°C and
boils at 19.4°C. In it are dissolved varying quantities of metallic
and non-metallic fluorides, such as boron trifluoride, sodium
fluoride, etc. When the oceans and lakes freeze, they do so from the
bottom up, so there is no layer of ice over free liquid.</p>
<h3>5. PLANTS AND PLANT METABOLISM</h3>
<p>The plants function by photosynthesis, taking HF as water from the
soil, and carbon tetrafluoride as the<span class="pagenum"><SPAN name="Page_xviii" id="Page_xviii"></SPAN></span> equivalent of carbon dioxide
from the air to produce chain compounds, such as:</p>
<div class="center"><ANTIMG src="images/image_03.jpg" alt="Table_02" width-obs="400" height-obs="219" /></div>
<p>and at the same time liberating free fluorine. This reaction could
only take place on a planet receiving lots of ultra-violet because so
much energy is needed to break up carbon tetrafluoride and
hydrofluoric acid. The plant catalyst (doubling for the magnesium in
chlorophyll) is nickel. The plants are colored in various ways. They
get their metals from the soil.</p>
<h3>6. ANIMALS AND ANIMAL METABOLISM</h3>
<p>Animals depend upon two main reactions for their energy, and for the
construction of their harder tissues. The soft tissues are about the
same as the plant molecules, but the hard tissues are produced by the
reaction:</p>
<div class="center"><ANTIMG src="images/image_04.jpg" alt="Table_03" width-obs="600" height-obs="159" /></div>
<p>resulting in a teflon boned and shelled organism. He's going to be
tough to do much with. Diatoms leave<span class="pagenum"><SPAN name="Page_xix" id="Page_xix"></SPAN></span> strata of powdered teflon. The
main energy reaction is:</p>
<div class="center"><ANTIMG src="images/image_05.jpg" alt="Table_04" width-obs="500" height-obs="159" /></div>
<p>The blood catalyst metal is titanium, which results in colorless
arterial blood and violet veinous, as the titanium flips back and
forth between tri and tetra-valent states.</p>
<h3>7. EFFECT ON INTRUDING ITEMS</h3>
<p>Water decomposes into oxygen and hydrofluoric acid. All organic matter
(earth type) converts into oxygen, carbon tetrafluoride, hydrofluoric
acid, etc., with more or less speed. A rubber gas mask lasts about an
hour. Glass first frosts and then disappears. Plastics act like
rubber, only a little slower. The heavy metals, iron, nickel, copper,
monel, etc., stand up well, forming an insoluble coat of fluorides at
first and then doing nothing else.</p>
<h3>8. WHY GO THERE?</h3>
<p>Large natural crystals of fluorides, such as calcium difluoride,
titanium tetrafluoride, zirconium tetrafluoride, are extremely useful
in optical instruments of various forms. Uranium appears as uranium
hexafluoride, all ready for the diffusion process. Compounds of such
non-metals as boron are obtainable<span class="pagenum"><SPAN name="Page_xx" id="Page_xx"></SPAN></span> from the atmosphere in high purity
with very little trouble. All metallurgy must be electrical. There are
considerable deposits of beryllium, and they occur in high
concentration in its ores.</p>
<hr style="width: 65%;" />
<p><span class="pagenum"><SPAN name="Page_1" id="Page_1"></SPAN></span></p>
<h2><SPAN name="PROLOGUE" id="PROLOGUE"></SPAN>PROLOGUE</h2>
<h3>On Satan's Footstool</h3>
<p>The big armor-tender vibrated, gently and not unpleasantly, as the
contragravity field alternated on and off, occasionally varying its
normal rate of five hundred to the second when some thermal updraft
lifted the vehicle and the automatic radar-altimeter control acted to
alter the frequency and lower it again. Sometimes it rocked slightly,
like a boat on the water, and, in the big screen which served in lieu
of a window at the front of the control cabin, the dingy-yellow
landscape would seem to tilt a little. If unshielded human eyes could
have endured the rays of Nu Puppis, Niflheim's primary, the whole scene
would have appeared a vivid Saint Patrick's Day green, the effect of
the blue-predominant light on the yellow atmosphere. The outside
'visor-pickup, however, was fitted with filters which blocked out the
gamma-rays and X-rays and most of the ultra-violet-rays, and added the
longer light-waves of red and orange which were absent, so that things
looked much as they would have under the light of a G0-type star like
Sol. The air was faintly yellow, the sky was yellow with a greenish
cast, and the clouds were green-gray.</p>
<p>A thousand feet below, the local equivalent of a forest grew, the
trees, topped with huge ragged leaves, looking like hundred-foot
stalks of celery. There would be animal life down there, too—little
round things,<span class="pagenum"><SPAN name="Page_2" id="Page_2"></SPAN></span> four inches across, like eight-legged crabs, gnawing at
the vegetation, and bigger things, two feet long, with articulated
shell-armor and sixteen legs, which fed on the smaller herbivores.
Beyond, in the middleground, was open grassland, if one could so call
a mat of wormlike colorless or pastel-tinted sprouts, and a river
meandered through it. On the skyline, fifty miles away, was a range of
low dunes and hills, none more than a thousand feet high.</p>
<p>No human had ever set foot on the surface, or breathed the air, of
Niflheim. To have done so would have been instant death; the air was a
mixture of free fluorine and fluoride gasses, the soil was metallic
fluorides, damp with acid rains, and the river was pure hydrofluoric
acid. Even the ordinary spacesuit would have been no protection; the
glass and rubber and plastic would have disintegrated in a matter of
minutes. People came to Niflheim, and worked the mines and uranium
refineries and chemical plants, but they did so inside power-driven
and contragravity-lifted armor, and they lived on artificial
satellites two thousand miles off-planet. This vehicle, for instance,
was built and protected as no spaceship ever had to be, completely
insulated and entered only through a triple airlock—an outer lock,
which would be evacuated outward after it was closed, a middle lock
kept evacuated at all times, and an inner lock, evacuated into the
interior of the vehicle before the middle lock could be opened.
Niflheim was worse than airless, much worse.</p>
<p>The chief engineer sat at his controls, making the minor lateral
adjustments in the vehicle's position which were not possible to the
automatic controls. One of the radiomen was receiving from the orbital
base; the other was saying, over and over, in an ex<span class="pagenum"><SPAN name="Page_3" id="Page_3"></SPAN></span>asperatedly
patient voice: "Dr. Murillo. Dr. Murillo. Please come in, Dr.
Murillo." At his own panel of instruments, a small man with grizzled
black hair around a bald crown, and a grizzled beard, chewed nervously
at the stump of a dead cigar and listened intently to what was—or for
what wasn't—coming in to his headset receiver. A couple of assistants
checked dials and refreshed their memories from notebooks and peered
anxiously into the big screen. A large, plump-faced, young man in
soiled khaki shirt and shorts, with extremely hairy legs, was doodling
on his notepad and eating candy out of a bag. And a black-haired girl
in a suit of coveralls three sizes too big for her, and, apparently,
not much of anything else, lounged with one knee hooked over her
chair-arm, staring into the screen at the distant horizon.</p>
<p>"Dr. Murillo. Dr. Mur—" The radioman broke off in mid-syllable and
listened for a moment. "I hear you, doctor, go ahead." Then, a moment
later "What's your position, now, doctor?"</p>
<p>"I can see them," the girl said, lifting a hand in front of her. "At
two o'clock, about one of my hand's-breadths above the horizon."</p>
<p>The man with the grizzled beard put his face into the fur around the
eyepiece of the telescopic-'visor and twisted a dial. "You have good
eyes, Miss Quinton," he complimented. "Only four personal armors;
Ahmed, ask him where the fifth is."</p>
<p>"We only see four of your personal-armors," the radioman said. "Who's
missing, and why?" He waited for a moment, then lowered the hand-phone
and turned. "The fifth one's inside the handling-machine. One of the
Ullerans. Gorkrink."</p>
<p>The larger of the specks that had appeared on the horizon resolved
itself into a handling-machine, a thing<span class="pagenum"><SPAN name="Page_4" id="Page_4"></SPAN></span> like an oversized
contragravity-tank, with a bulldozer-blade, a stubby derrick-boom
instead of a gun, and jointed, claw-tipped arms to the sides. The
smaller dots grew into personal armor—egg-shaped things that sprouted
arms and grab-hooks and pushers in all directions. The man with the
grizzled beard began talking rapidly into his hand-phone, then hung it
up. There was a series of bumps, and the armor-tender, weightless on
contragravity, shook as the handling-machine came aboard.</p>
<p>"You ever see any nuclear bombing, Miss Quinton?" the young man with
the hairy legs asked, offering her his candy bag.</p>
<p>"Only by telecast, back Sol-side," she replied, helping herself.
"Test-shots at the Federation Navy proving-ground on Mars. I never
even heard of nuclear bombs being used for mining till I came here,
though."</p>
<p>"Well, if this turns out as well as the other job, three months ago,
it'll be something to see," he promised. "These volcanoes have been
dormant for, oh, maybe as long as a thousand years; there ought to be
a pretty good head of gas down there. And the magma'll be thick,
viscous stuff, like basalt on Terra. Of course, this won't be anything
like basalt in composition—it'll be intensely compressed metallic
fluorides, with a very high metal-content. The volcanoes we shot three
months ago yielded a fine flow of lava with all sorts of
metals—nickel, beryllium, vanadium, chromium, indium, as well as
copper and iron."</p>
<p>"What sort of gas were you speaking about?" she asked.</p>
<p>"Hydrogen. That's what's going to make the fireworks; it combines
explosively with fluorine. The hydrogen-fluorine combination is what
passes for combustion here; the result is hydrofluoric acid, the<span class="pagenum"><SPAN name="Page_5" id="Page_5"></SPAN></span>
local equivalent of water. See, the metallic core of this planet is
covered, much less thickly than that of Terra, with fluoride
rock—fluorspar, and that sort of thing. There's nothing like granite
here, for instance. That's why those big dunes, out there, are the
best Niflheim has in the way of mountains. The subsurface hydrogen is
produced when the acid filters down through the rock, combines with
pure metals underneath."</p>
<p>"Dr. Murillo's inside, now," the radioman said. "Just came out of the
inner airlock. He'll be up as soon as he gets out of his
pressure-suit."</p>
<p>"As soon as he gets here, I'll touch it off," the bearded man said.
"Everything set, de Jong?"</p>
<p>"Everything ready, Dr. Gomes," one of his assistants assured him.</p>
<p>The door at the rear of the control-cabin opened, and Juan Murillo,
the seismologist, entered, followed by an assistant. Murillo was a big
man, copper-skinned, barrel-chested; he looked like a third-or
fourth-generation Martian, of Andes Indian ancestry. He came forward
and stood behind Gomes' chair, looking down at the instruments. His
assistant stopped at the door. This assistant was not human. He was a
biped, vaguely humanoid, but he had four arms and a face like a
lizard's, and, except for some equipment on a belt, he was entirely
naked.</p>
<p>He spoke rapidly to Murillo, in a squeaking jabber. Murillo turned.</p>
<p>"Yes, if you wish, Gorkrink," he said, in the
English-Spanish-Afrikaans-Portuguese mixture that was Sixth Century,
A.E., Lingua Terra. Then he turned back to Gomes as the Ulleran sat
down in a chair by the door.</p>
<p>"Well, she's all yours, Lourenço, shoot the works."<span class="pagenum"><SPAN name="Page_6" id="Page_6"></SPAN></span></p>
<p>Gomes stabbed the radio-detonator button in front of him. A voice came
out of the PA-speaker overhead: "In sixty seconds, the bombs will be
detonated ... thirty seconds ... fifteen seconds ... ten seconds ...
five seconds, four seconds, three seconds, two seconds, one
second...."</p>
<p>Out on the rolling skyline, fifty miles away, a lancelike ray of
blue-white light shot up into the gathering dusk—a clump of five
rays, really, from five deep shafts in an irregular pentagon half a
mile across, blended into one by the distance. An instant later, there
was a blinding flash, like sheet-lightning, and a huge ball of
varicolored fire belched upward, leaving a series of smoke-rings to
float more slowly after it. That fireball flattened, then spread to
form the mushroom-head of a column of incandescent gas that mounted to
overtake it, engorging the smoke-rings as it rose, twisting, writhing,
changing shape, turning to dark smoke in one moment and belching flame
and crackling with lightning the next. The armor-tender began to pitch
and roll; it was all the engineer and one of the assistants could do,
together, to keep it level.</p>
<p>"In about half an hour," the large young man told the girl, "the real
fireworks should be starting. What's coming up now is just small
debris from the nuclear blast. When the shockwaves get down far enough
to crack things open, the gas'll come up, and then steam and ash, and
then the magma. This one ought to be twice as good as the one we shot
three months ago; it ought to be every bit as good as Krakatoa, on
Terra, in 59 Pre-Atomic."</p>
<p>"Well, even this much was worth staying over for," the girl said,
watching the screen.</p>
<p>"You going on to Uller on the <i>City of Canberra</i>?"<span class="pagenum"><SPAN name="Page_7" id="Page_7"></SPAN></span> Lourenço Gomes
asked. "I wish I were; I have to stay over and make another shot, in a
month or so, and I've had about all of Niflheim I can take, now. The
sooner I get onto a planet where they don't ration the air, the better
I'll like it."</p>
<p>"Well, what do you know!" the large young man with the hairy legs
mock-marveled. "He doesn't like our nice planet!"</p>
<p>"Nice planet!" Gomes muttered something. "They call Terra God's
Footstool; well, I'll give you one guess who uses this thing to prop
his cloven hoofs on."</p>
<p>"When are you going to Terra?" the girl asked him.</p>
<p>"Terra? I don't know, a year, two years. But I'm going to Uller on the
next ship—the <i>City of Pretoria</i>—if we get the next blast off in
time. They want me to design some improvements on a couple of
power-reactors, so I'll probably see you when I get there."</p>
<p>"Here she comes!" the chief engineer called. "Watch the base of the
column!"</p>
<p>The pillar of fiery smoke and dust, still boiling up from where the
bombs had gone off far underground, was being violently agitated at
the bottom. A series of new flashes broke out, lifting and spreading
the incandescent radioactive gasses, and then a great gush of flame
rose. A column of pure hydrogen must have rushed up into the vacuum
created by the explosion; the next blast of flame, in a lateral sheet,
came at nearly ten thousand feet above the ground, and great rags of
fire, changing from red to violet and back through the spectrum to red
again, went soaring away to dissipate in the upper atmosphere. Then
geysers of hot ash and molten rock spouted upward; some of the
white-hot debris landed almost at the acid river, half-way to the
armor-tender.<span class="pagenum"><SPAN name="Page_8" id="Page_8"></SPAN></span></p>
<p>"We've started a first-class earthquake, too," the Hispano-Indian
Martian Murillo said, looking at the instruments. "About six big
cracks opening in the rock-structure. You know, when this quiets down
and cools off, we'll have more ore on the surface than we can handle
in ten years, and more than we could have mined by ordinary means in
fifty."</p>
<p>About four miles from the original blast, another eruption began with
a terrific gas-explosion.</p>
<p>"Well, that finishes our work," the large young man said, going to a
kitbag in the corner of the cabin and getting out a bottle. "Get some
of those plastic cups, over there, somebody; this one calls for a
drink."</p>
<p>"That's right," Gomes said. "You do something once, it may be an
accident; you repeat the performance, and it's a success." He began
pushing papers aside on his desk, and the girl in the too-ample
coveralls brought drinking cups.</p>
<p>The Ulleran, in the background, rose quickly and squeaked
apologetically. Murillo nodded. "Yes, of course, Gorkrink. No need for
you to stay here." The Ulleran went out, closing the door behind him.</p>
<p>"That taboo against Ullerans and Terrans watching each other eat and
drink," Murillo said. "What is that, part of their religion?"</p>
<p>"No, it's their version of modesty," the girl replied. "Like some of
our sex-inhibitions, which they can't even begin to understand.... But
you were speaking to him in Lingua Terra; I didn't know any of them
understood it."</p>
<p>"Gorkrink does," Murillo said, uncorking the bottle and pouring into
the plastic cups. "None of them can speak it, of course, because of
the structure of their vocal organs, any more than we can speak their
languages without artificial aids. But I can talk to him<span class="pagenum"><SPAN name="Page_9" id="Page_9"></SPAN></span> in Lingua
Terra without having to put one of those damn gags in my mouth, and he
can pass my instructions on to the others. He's been a big help; I'll
be sorry to lose him."</p>
<p>"Lose him?"</p>
<p>"Yes, his year's up; he's going back to Uller on the <i>Canberra</i>. You
know, it's impossible to keep some trace of fluorine from the air in
the handling-machines, or even out on the orbiters, and it plays the
devil with their lungs. He wanted to stay on another three months, to
help with the next shot, but the medics wouldn't hear of it.... He's
from Keegark, wherever on Uller that is; claims to be a prince, or
something. I know all the other geeks kowtow to him. But he's a damn
good worker. Very smart; picks things up the first time you tell him.
I'll recommend him unqualifiedly for any kind of work with
contragravity or mechanized equipment."</p>
<p>They all had drinks, now, except the chief engineer, who wanted a
rain-check on his.</p>
<p>"Well, here's to us," Murillo said. "The first A-bomb miners in
history...."</p>
