ere. He rolls out of his hammock  and walks naked in  the warm
rain to wash himself. Goto Dengo has a job to do.


     <B>Chapter 67 COMPUTER</B>


     Lieutenant Colonel Earl Comstock of The Electrical Till Corporation and
the United States Army, in that order, prepares for today's routine briefing
from  his subordinate, Lawrence Pritchard Waterhouse, much as  a  test pilot
readies himself to be ripped into the stratosphere with a  hot rocket engine
under his ass. He turns  in early the  night before, wakes up late, talks to
his aide and makes sure  that (a) plenty of hot coffee  is available and (b)
none of it will be given to Waterhouse. He gets two wire recorders set up in
the room,  in case  either goes on the fritz, and  brings in a team of three
crack  stenographers with  loads of  technical  savvy.  He has a  couple  of
fellows in his section also ETC employees during peacetime who are real math
whizzes, so he brings them in too. He gives them a little pep talk:
     "I do not expect you fellows to  understand what the fuck Waterhouse is
talking about. I'm gonna be running after him as fast as I can. You just hug
his legs and hold on for dear life so that I  can sort of  keep his backside
in  view as long as  possible." Comstock is  proud of  this analogy, but the
math whizzes seem baffled. Testily, he  fills  them  in on the always tricky
literal  vs.  figurative  dichotomy.  Only  twenty  minutes  remain   before
Waterhouse's  arrival; right on schedule, Comstock's aide comes through  the
room with a tray  of benzedrine  tablets. Comstock takes  two, attempting to
lead  by  example. "Where's  my  darn  chalkboard team?" he demands,  as the
powerful stimulant  begins  to  rev  up  his pulse. Into the  room come  two
privates equipped  with  blackboard erasers  and damp chamois cloths, plus a
three  man photography  team. They  set up a pair of  cameras aimed  at  the
chalkboard, plus a couple of  strobe lights, and lay in a  healthy stock  of
film rolls.
     He checks his watch. They are running five  minutes behind schedule. He
looks out the window and sees that his jeep has returned; Waterhouse must be
in the building. "Where is the extraction team?" he demands.
     Sergeant  Graves is there a few  moments later.  "Sir,  we  went to the
church as directed, and located him, and, uh " He coughs against the back of
his hand.
     "And what?"
     "And who is more like it, sir," says Sergeant Graves, sotto voce. "He's
in the lavatory right now, cleaning up, if you know what I mean." He winks.
     "Ohhhh," says Earl Comstock, cottoning on to it.
     "After all," Sergeant Graves  says, "you can't <I>blow out</I> the <I>rusty pipes</I>
of  your <I>organ</I>  unless  you have  a  <I>nice little  assistant</I> to  get the  job
<I>properly done."</I>

     Comstock tenses. "Sergeant Graves it is critically  important for me to
<I>know did the job get properly done?"</I>

     Graves furrows his brow, as if pained by the very question. "Oh, by all
means sir. We wouldn't dream of  interrupting such an  operation. That's why
we are late begging your pardon."
     "Don't  mention it," Comstock stays,  slapping Graves  heartily  on the
shoulder. "That is why I try to give my men broad discretion. It has been my
opinion  for  quite  some time  that Waterhouse  is  badly in  need  of some
relaxation.  He concentrates  a  little  too hard on his work.  Sometimes  I
frankly cannot tell whether  he is saying something very brilliant, or  just
totally incoherent. And I think you have made a  pivotal, Sergeant Graves, a
pivotal  contribution  to today's meeting by having the good sense  to stand
off  long  enough for  Waterhouse's affairs to  be  set  in order." Comstock
realizes that he  is breathing very fast,  and his  heart is pounding madly.
Perhaps he overdid the benzedrine?
     Waterhouse drifts into the room  ten minutes  later on flaccid legs, as
if he had inadvertently left his own skeleton behind in bed. He barely makes
it  to his designated seat and  thuds into it like a sack of guts, popping a
few strands  of wicker out of its bottom. He is  breathing raggedly  through
his mouth, blinking heavy eyelids frequently.
     "Looks like today's going  to  be  a milk run, men!" Comstock announces
brightly.  Everyone except Waterhouse snickers.  Waterhouse has  been in the
building for  a quarter of  an  hour, and  it took  at  least that  long for
Sergeant Graves to drive him here from the church, and  so  it  has been  at
least half  an  hour. And yet, to look  at him,  you'd  think  that  it  had
happened five seconds ago.
     "Someone pour that man a cup of coffee!" Comstock orders. Someone does.
Being  in  the military  is  <I>amazing;</I>  you  give orders, and  things happen.
Waterhouse does not drink, or even touch, the coffee,  but at least it gives
his eyes something to focus on. Those orbs wander around under their rumpled
lids for a while, like ack  ack guns  trying  to track a  house fly,  before
finally fixing on the white coffee mug. Waterhouse clears his throat at some
length,  as  if preparing to  speak,  and the room  goes silent. It  remains
silent  for  about  thirty seconds. Then Waterhouse mumbles  something  that
sounds like "coy."
     The stenographers take it down in unison.
     "Beg pardon?" says Comstock.
     One of the math whizzes says, "He might be talking about Coy Functions.
I think I  saw them when I  was flipping through a  graduate  math  textbook
once."
     "I thought he was saying 'quantum' something," says the other ETC man.
     "Coffee," Waterhouse says, and heaves a deep sigh.
     "Waterhouse,"  says  Comstock, "how  many  fingers  am I  holding  up?"
Waterhouse seems to realize  that there are other people in the room now. He
closes his mouth, and his nostrils flare as air begins to rush through them.
He tries to move one of  his hands, realizes that he is  sitting on  it, and
shifts heavily to and fro until it flops loose. He gets his eyes all the way
open,  providing a really  good, clear  view  of that coffee mug. He  yawns,
stretches, and farts.
     "The Nipponese cryptosystem that we call Azure is the same thing as the
German system that we call Pufferfish," he announces. "Both of them are also
related somehow  to another, newer cryptosystem I  have dubbed Arethusa. All
of these have  something to do with gold. Probably gold mining operations of
some sort. In the Philippines."
     Whammo!  The stenographers go into  action. The photographer  fires off
his strobes,  even though there's nothing  to  take pictures of just nerves.
Comstock glances beadily at  his wire  recorders, makes sure those reels are
spinning. He is a little unnerved by how rapidly Waterhouse is coming up  to
speed. But one  of the  responsibilities of leadership is to mask one's  own
fears, to project confidence at all  times.  Comstock  grins  and says, "You
sound awfully sure of yourself, Waterhouse! I wonder  if you  can get me  to
feel that same level of confidence."
     Waterhouse  frowns at the coffee  mug. "Well, it's all  math," he says.
"If  the  math  works,  why then you  <I>should</I> be sure of yourself. That's the
whole point of math."
     "So you have a mathematical basis for making this assertion?"
     "Assertions," Waterhouse says. "Assertion number one is that Pufferfish
and Azure  are different  names for  the same cryptosystem. Assertion number
two is  that Pufferfish/Azure is a cousin of  Arethusa.  Three: all of these
cryptosystems are related to gold. Four: mining. Five: Philippines."
     "Maybe  you could just chalk those  up  on  the  blackboard  as  you go
along," Comstock says edgily.
     "Glad  to,"  Waterhouse  says.  He  stands  up  and  turns  toward  the
blackboard, freezes for a couple of seconds, then turns back  around, lunges
for the coffee  mug, and drains it before Comstock  or any of his aides  can
rip  it  from his  grasp. Tactical  error!  Then  Waterhouse  chalks  up his
assertions. The photographer records it. The privates  massage their chamois
cloths and glance nervously in Comstock's direction.
     "Now, you have  some sort  of, er, mathematical proof for each  one  of
these assertions?" Comstock asks. Math isn't his  bag,  but running meetings
is, and  what Waterhouse has  just  chalked up on that board  looks, to him,
like the rudiments of an agenda. And Comstock feels a lot better when he has
an agenda. Without an agenda, he's like a grunt running around in the jungle
without a map or a weapon.
     "Well,  sir, that's one way to look  at it," Waterhouse says after some
thought.  "But it  is much more elegant to view all of these as  corollaries
stemming from the same underlying theorem."
     "Are you telling me that you have succeeded in breaking  Azure? Because
if so, congratulations are in order!" Comstock says.
     "No. It is still unbroken. But I <I>can</I> extract information from it."
     This is the  moment where the  joystick  snaps off  in Comstock's hand.
Still, he can  pound haplessly on the control  panel.  "Well, would you mind
taking them one at a time, at least?"
     "Well,  let's  just take, for example,  Assertion Four,  which  is that
Azure/Pufferfish has something to do with mining." Waterhouse sketches out a
freehand map of the  Southwest Pacific  theater of operations, from Burma to
the Solomons, from  Nippon to New Zealand. It takes him about sixty seconds.
Just  for  grins,  Comstock  pulls a  printed  map out of his  clipboard and
compares it against Waterhouse's version. They are basically identical.
     Waterhouse  draws  a  circle with  a letter A in it at the entrance  to
Manila Bay. "This is one of the stations that transmits Azure messages."
     "You know that from huffduff, correct?"
     "That's right."
     "Is that on Corregidor?"
     "One of the smaller islands near Corregidor."
     Waterhouse draws another circle A  in Manila itself, one in  Tokyo, one
in Rabaul, one in Penang, one in the Indian Ocean.
     "What's that?" Comstock asks.
     "We  picked  up an  Azure  transmission  from  a  German  U boat here,"
Waterhouse says.
     "How do you know it was a German U boat?"
     "Recognized  the  fist," Waterhouse says.  "So,  this  is  the  spatial
arrangement of  Azure transmitters not counting the stations  in Europe that
are making Pufferfish transmissions, and hence, according to  Assertion One,
are part of the same  network. Anyway, now let  us say that an Azure message
originates from Tokyo on a certain date. We don't know what it says, because
we haven't broken Azure yet. We just know that the message went out to these
places."  Waterhouse draws lines  radiating downward  from  Tokyo to Manila,
Rabaul, Penang. "Now,  each one  of  these cities  is a major military base.
Consequently,  each  is   the  source  of  a  steady   stream  of   traffic,
communicating  with all of  the  Nipponese bases in its region."  Waterhouse
draws  shorter lines radiating from  Manila  to  various  locations  in  the
Philippines, and from Rabaul to New Guinea and the Solomons.
     "Correction, Waterhouse," Comstock says. "We own New Guinea now."
     "But I'm going back  in  time!"  Waterhouse  says. "Back to  1943, when
there  were Nip bases all  along the north coast  of New Guinea, and through
the Solomons. So, let  us  say that  within a brief window of time following
this  Azure  message  from Tokyo, a number of  messages are transmitted from
places like Rabaul and Manila to smaller bases in  those areas. Some of them
are  in  ciphers  that  we  have  learned  how  to  break.  Now,  it is  not
unreasonable  to suppose  that some of these messages  were  sent out  as  a
consequence of whatever orders were contained in that Azure message."
     "But  those  places send  out thousands of  messages a  day,"  Comstock
protests. "What makes you  think that you can pick out the messages that are
a consequence of the Azure orders?"
     "It's just a brute force statistics problem," Waterhouse says. "Suppose
that Tokyo sent the Azure  message to  Rabaul  on  October  15th, 1943. Now,
suppose I take all of the messages that were sent out from Rabaul on October
14th  and  I  index  them  in  various ways:  what  destinations  they  were
transmitted to, how long  they were,  and, if we  were able to decrypt them,
what their subject matter  was. Were they orders for troop movements? Supply
shipments?  Changes  in  tactics or  procedures?  Then,  I take  all of  the
messages that were  sent out from  Rabaul on October  16th the day after the
Azure  message came  in from Tokyo  and  I run exactly  the same statistical
analysis on them."
     Waterhouse steps back from  the chalkboard and  turns into  a  blinding
fusillade  of  strobe  lights.  "You see, it is all about information  flow.
Information  flows from Tokyo to Rabaul. We don't know  what the information
was. But it will, in some way, influence what Rabaul does afterwards. Rabaul
is  changed,  irrevocably,  by  the  arrival  of  that information,  and  by
comparing Rabaul's observed behavior  before  and  after that change, we can
make inferences."
     "Such as?" Comstock says warily.
     Waterhouse shrugs. "The differences are very  slight. They hardly stand
out  from the noise. Over the course of the war, thirty  one Azure  messages
have  gone  out from Tokyo, so I have that many data sets to work with.  Any
one data set by itself might not tell me anything. But when I combine all of
the data sets together giving me greater depth then I can see some patterns.
And one of the patterns that I most definitely see is that, on the day after
an Azure message went  out to,  say, Rabaul, Rabaul was much more likely  to
transmit messages having to do with mining engineers. This has ramifications
that can be traced all the way back until the loop is closed."
     "Loop is closed?"
     "Okay. Let's  take it  from the top.  Azure message  goes from Tokyo to
Rabaul," Waterhouse says, drawing a  heavy line down  the chalkboard joining
those two cities. "The next  day, a message in some other crypto system  one
that we have broken goes from Rabaul to a submarine operating out of  a base
here, in  the Moluccas. The message states  that the submarine is to proceed
to an outpost on the north coast of New Guinea and  pick up four passengers,
who are  identified by name. From  our archives, we know  who these men are:
three  aircraft mechanics and one  mining engineer.  A few days  later,  the
submarine transmits from the Bismarck  Sea stating that it  has picked those
men up. A few days after that, our waterfront spies in Manila inform us that
the  same submarine has  showed  up  there. On the  same day, another  Azure
message is transmitted from Manila  back up to Tokyo," Waterhouse concludes,
adding a final line to the polygon, "closing the loop."
     "But that could  all be a series  of random, unconnected  events," says
one  of Comstock's  math whizzes, before  Comstock can say it. "The Nips are
desperate for aircraft mechanics. There's nothing unusual about this kind of
message traffic."
     "But there is  something  unusual about the patterns," Waterhouse says.
"If, a few months later, another submarine is sent, in the same way, to pick
up some mining engineers and some surveyors who have been trapped in Rabaul,
and, upon its arrival in  Manila, another  Azure message is sent from Manila
up to Tokyo, it begins to look very suspicious."
     "I  don't know," Comstock stays, shaking his head. "I'm  not sure  if I
can  sell  this  to  the  General's  staff.  It's  too  much  of  a  fishing
expedition."
     "Correction,  sir, it <I>was</I> a fishing expedition. But now  I'm <I>back</I>  from
the fishing expedition, and I've got the fish!" Waterhouse storms out of the
room  and down the  hall toward  his lab  half the  fucking wing. Good thing
Australia is a big continent, because Waterhouse is  going to take all of it
if he's  not held sternly  in check. Fifteen seconds later he's back  with a
stack of ETC cards a foot high, which he pounds down on the  tabletop. "It's
all right here."
     Comstock has never fired a gun in his life, but  he knows card punching
and  reading machinery like a  jarhead knows his  Springfield,  and he's not
impressed.   "Waterhouse,  that  stack  of   cards  carries  about  as  much
information as a letter home to Mom. Are you trying to tell me "
     "No, this is just the summary. The result of the statistical analysis."
     "Why the hell did you punch it onto ETC cards? Why  not  just turn in a
plain old typed report like everyone else?"
     "I didn't punch it," Waterhouse says. "The machine punched it."
     "The machine punched it," Comstock says very slowly.
     "Yes. When it  was done performing  the analysis." Waterhouse  suddenly
breaks into  his  braying laugh. "You didn't think this was the raw  inputs,
did you?"
     "Well, I "
     "The inputs filled several rooms. I had to  run almost every message we
have intercepted through the whole war through this  analysis. Re member all
those  trucks I requisitioned  a few weeks ago? Those  trucks  were  just to
carry the cards back and forth from storage."
     "Jesus Christ!"  Comstock  says. He  remembers  the  trucks now,  their
incessant comings and  goings,  fender benders in  the motor  pool,  exhaust
fumes coming through his window, the enlisted men shoving heavy carts up and
down the hallways, laden with boxes. Running over people's feet. Scaring the
secretaries.
     And  the  noise.  The noise, the  noise,  from  Waterhouse's  goddamned
machine. Flowerpots vibrating their way off file cabinets, standing waves in
coffee cups.
     "Wait a sec," says one of the ETC  men, with  the nasal skepticism of a
man who has just realized he's being bullshitted. "I saw those trucks. I saw
those cards. Are  you trying  to get  us to believe that  you were  actually
running a statistical analysis on each and every single one of those message
decrypts?"
     Waterhouse looks a little defensive. "Well, that was the only way to do
it!"
     Comstock's  math  whiz is homing in for the kill now. "I agree that the
only way to accomplish the analysis that is implied by that" he waves at the
mandala of  intersecting polygons on Waterhouse's map "is to go through  all
of  those truckloads of old decrypts one by one. That is  clear. That is not
what we are objecting to."
     "What are you objecting to, then?"
     The whiz laughs angrily.  "I'm just worried about the <I>inconvenient fact</I>
that there is  no machine in  the whole world that is  capable of processing
all of that data, that fast."
     "Didn't you hear the noise?" Waterhouse asks.
     "We all  heard the goddamn noise," Comstock says. "What  does that have
to do with anything?"
     "Oh," Waterhouse says, and rolls his eyes at his own stupidity. "That's
right. Sorry. Maybe I should have explained that part first."
     "What part?" Comstock asks.
     "Dr.  Turing,  of Cambridge  University, has pointed out  that bobbadah
bobbadah hoe daddy yanga langa furjeezama  bing  jingle oh yeah," Waterhouse
says, or words  to that effect.  He  pauses for breath, and  turns fatefully
towards the blackboard. "Do  you  mind if I erase  this?"  A  private lunges
forward with an eraser. Comstock sinks  into a chair  and  grips its arms. A
stenographer reaches for  a benzedrine  tablet. An ETC man chomps down  on a
number two  lead pencil like a dog on a drumstick. Strobes flash. Waterhouse
grabs  a  fresh  stick  of  chalk, reaches up, and presses  its tip  to  the
immaculate  slate.  The crisp edge of the stick fractures with a slight pop,
and a  tiny spray of chalk particles drifts  to the  floor spreading  into a
narrow parabolic cloud. Waterhouse bows his head for a minute, like a priest
getting ready to stride up the aisle, and then draws a deep breath.
     The  benzedrine wears off five hours later and  Comstock  finds himself
sprawled  across a  table in  a  room  filled  with  haggard, exhausted men.
Waterhouse  and  the  privates  are  pasty with  chalk  dust,  giving them a
ghoulish appearance. The stenographers  are  surrounded with used  pads, and
frequently stop writing  to  flap their  limp hands in  the air  like  white
flags. The  wire recorders  are spinning uselessly, one  reel  full  and one
empty. Only  the photographer  is  still  going  strong, hitting that strobe
every time Waterhouse manages to fill the chalkboard.
     Everything  smells  like   underarm   sweat.  Comstock  realizes   that
Waterhouse is looking at him expectantly. "See?" Waterhouse asks.
     Comstock  sits up and glances furtively at his own legal  pad, where he
hoped to draw up an agenda.  He sees  Waterhouse's four assertions, which he
copied down during the  first  five minutes of the meeting, and then nothing
except a  tangled  field  of  spiky doodles  surrounding the  words BURY and
DISINTER.
     It  behooves  Comstock to say  <I>something.</I>  "This  thing, the,  uh,  the
burying procedure, that's the, uh "
     "The  key  feature!" Waterhouse says  brightly.  "See,  these ETC  card
machines are great for input and output.  We've got that  covered. The logic
elements are straightforward enough. What was  needed was a way  to give the
machine memory,  so that  it could, to use Turing's terminology,  bury  data
quickly,  and just as quickly disinter it. So  I made one of those. It is an
electrical device, but its  underlying principles  would be familiar to  any
organ maker."
     "Could I, uh, see it?" Comstock asks.
     "Sure! It's down in my lab."
     Going to  see  it is more complicated. First everyone  has to  use  the
toilet,  then the cameras and strobes have to  be moved down  to the lab and
set up. When  they've  all filed in, Waterhouse is standing next to  a giant
rack of pipes with thousands of wires hanging out of it.
     "That's  it?" Comstock  says, when the group  is finally assembled. Pea
sized drops of mercury are scattered around  the floor  like ball  bearings.
The flat soles of Comstock's  shoes explode  them into bursts rolling in all
directions.
     "That's it."
     "What did you call it again?"
     "The RAM," Waterhouse says. "Random Access Memory. I was going to put a
picture  of a ram on it. Y'know, one of those sheeps with the big huge curly
horns?"
     "Yes."
     "But I didn't have time,  and I'm not that good  at  drawing pictures."
Each pipe is four inches in diameter and thirty two feet long. There must be
a hundred of them,  at least Comstock is trying to remember that requisition
that he signed, months ago Waterhouse had ordered enough drain pipe to plumb
a whole goddamn military base.
     The  pipes are laid out horizontally, like a  rank  of organ pipes that
has been knocked flat. Stuck  into one  end of  each  pipe is a little paper
speaker ripped from an old radio.
     "The  speaker plays  a signal a  note that  resonates in the pipe,  and
creates a standing wave," Waterhouse says. "That means that in some parts of
the  pipe, the  air pressure is low,  and in other parts  it is high." He is
backing down the  length of one of  the pipes,  making chopping motions with
his hand. "These U tubes are full of mercury." He points to one of several U
shaped glass tubes that are plumbed into the bottom of the long pipe.
     "I can  see that very  plainly, Waterhouse," Comstock says.  "Could you
keep   backing  up   to  the  next  one?"  he  requests,  peering  over  the
photographers'  shoulder through  the viewfinder.  "You're blocking my  view
that's  better  farther farther  " because  he  can still  see  Waterhouse's
shadow. "That's good. Hit it!"
     The photographer pulls the trigger, the strobe flares.
     "If  the air pressure in the organ  pipe is high, it pushes the mercury
down a little bit. If it's low, it sucks the mercury up. I put an electrical
contact into each U tube just a couple  of wires separated by an air gap. If
those wires are high  and dry (like  because high air pressure  in the organ
pipe is shoving the mercury  down away  from them), no current flows. But if
they are immersed in the mercury (because low air pressure in the organ pipe
is sucking the mercury up  to cover them), then current flows  between them,
because mercury conducts electricity! So the U tubes produce a set of binary
digits that is like a picture of  the standing wave a graph of the harmonics
that make up the musical note  that is being played  on the speaker. We feed
that vector back to the  oscillator circuit  that is driving the speaker, so
that the vector of bits  keeps refreshing itself forever, unless the machine
decides to write a new pattern of bits into it."
     "Oh, so the ETC machinery  actually can  control  this thing?" Comstock
asks.
     Again with the  laugh. "That's the whole point! This is where the logic
boards bury and disinter the data!" Waterhouse  says. "I'll  show you!"  And
before  Comstock  can order him not to, Waterhouse  has nodded to a corporal
standing at the other end of the room, wearing the protective earmuffs  that
are generally  issued to the men who fire  the very  largest artillery. That
corporal nods and  hits a switch. Waterhouse  slams  his hands over his ears
and grins, showing a little too much gum for Comstock's taste, and then time
stops, or  something, as all of those pipes come alive playing variations on
the same low C.
     It's all Comstock  can do not  to drop  to his knees;  he has his hands
over his  ears, of course, but the sound's not  really coming in through his
ears,  it is entering his  torso directly, like X rays. Hot sonic tongs  are
rummaging through his viscera, beads of sweat  being vibrated loose from his
scalp, his nuts are hopping around like Mexican jumping beans. The crescents
of  mercury  in all those U  tubes  are  shifting up  and  down, opening and
closing the contacts,  but  systematically: it  is  not  turbulent  sloshing
around,  but  a  coherent  progression  of  discrete  controlled  shiftings,
informed by some program.
     Comstock would draw his sidearm and  put a  bullet through Waterhouse's
head, but he'd have to take one hand off one ear. Finally it stops.
     "The machine just calculated the first hundred numbers in the Fibonacci
sequence," Waterhouse says.
     "As  I  understand it,  this RAM is just the  part where you  bury  and
disinter the data," Comstock says,  trying to master the higher harmonics in
his own  voice,  trying  to sound and act  as  if he saw this kind  of thing
daily. "If you had  to  give a name to the  whole apparatus, what would  you
call it?"
     "Hmmm,"   Waterhouse  says.  "Well,   its  basic  job   is  to  perform
mathematical calculations like a computer."
     Comstock snorts. "A computer is a human being."
     "Well  ...  this  machine  uses  binary digits to  do its computing.  I
suppose you could call it a digital computer."
     Comstock writes  it  out in block  letters on  his  legal  pad: DIGITAL
COMPUTER.
     "Is this going to go into your report?" Waterhouse asks brightly.
     Comstock almost blurts <I>report? This</I> is my <I>report!</I>  Then a  foggy memory
comes  back to him. Something about Azure. Something about  gold mines. "Oh,
yeah," he  murmurs. <I>Oh, yeah, there's a war on.</I>  He considers it.  "Nah. Now
that  you mention it, this isn't even a footnote." He looks significantly at
his pair of hand picked math  whizzes,  who are gazing at  the  RAM  like  a
couple of  provincial Judean sheep shearers  getting their first look at the
Ark  of  the  Covenant.  "We'll  probably  just  keep  these photos for  the
archives. You know how the military is with its archives."
     Waterhouse goes into that dreadful laugh again.
     "Do you have anything else to report before we adjourn?" Comstock says,
desperate to silence him.
     "Well,  this work has given me  some  new ideas on  information  theory
which you might find interesting "
     "Write them down. Send them to me."
     "There's one other  thing. I don't know  if it is really  germane here,
but "
     "What is it, Waterhouse?"
     "Uh, well ... it seems that I'm engaged to be married!"


     <B>Chapter 68 CARAVAN</B>


     Randy has lost all  he owned, but gained an  entourage. Amy has decided
that she might as well come  north with him, as long as she happens to be on
this side of the Pacific Ocean.
     This  makes him  happy. The Shaftoe  boys,  Robin  and Marcus Aurelius,
consider themselves invited  along like  much  else that in  other  families
would  be  the  subject  of  extended  debate,  this  goes  without  saying,
apparently.
     This makes it  imperative that  they <I>drive</I> the thousand or so  miles to
Whitman, Washington, because the Shaftoe  boys are not  really the  sort who
are in position to  simply drop the hot rod  off at  the Park  'n' Ride, run
into the airport, and demand tickets  on the next flight to  Spokane. Marcus
Aurelius is a college sophomore on an ROTC scholarship and Robin's attending
some kind  of military prep  school. But even if they  did have that kind of
money  rattling around in their  pockets, actually spending it  would offend
their native frugality.  Or so Randy assumes,  for the first couple of days.
It's the obvious assumption  to make, given  that the  Cash Flow Issue seems
always to be on their mind.  For example the boys  made Herculean efforts to
consume every spoonful of  the gut busting vat of oatmeal  cooked by Amy the
morning  after  the  quake,  and  finding  it beyond  their  endurance  they
carefully decanted the remainder into a  Ziploc bag while fretting at length
about the high cost of Ziploc bags and didn't Randy have any old glass jelly
jars or  something, some  where in  the basement, that might be unbroken and
usable for this purpose.
     Randy  has had  plenty  of  time to  disabuse himself of  this  fallacy
(namely that their airplane avoidance is dictated by financial  constraints)
and to draw the real reason out of them after they have dropped Amy's U Haul
off near SFO and begun to caravan northwards in the Acura and the jacked up,
thundering Impala. People are rotated from car to  car  whenever  they stop,
according to some system that no one is  divulging to Randy, but that always
situates him alone  in a car with either  Robin or Marcus  Aurelius. Both of
them are too dignified to spill their guts on light pretexts, and too polite
to assume that Randy gives a shit about anything they think, and perhaps too
basically suspicious  of Randy to  share  a whole lot with him. Some kind of
bonding is required first. The ice doesn't start to break up until  Day 2 of
the drive,  after they have all slept  in an  Interstate  5  rest  area near
Redding  in the  reclined seats  of the vehicles  (each of the  Shaftoe boys
solemnly and  separately informs him that the  chain  of  lodgings known  as
Motel 6 is one giant con game, that if those rooms ever did cost six dollars
a  night,  which is doubtful, they  certainly don't now,  and  many  are the
innocent young travelers who have been drawn in by  the siren calls of those
fraudulent  signs  rising above interstate cloverleaves; they try  to  sound
impartial and wise about it, but  the way  their faces flush and their  eyes
glance  aside  and their voices  rise makes  Randy  suspect  he  is actually
listening  to some thinly veiled personal and recent history). Again without
anyone saying anything,  it is taken to be obvious that  Amy, as the female,
will require her own car to  sleep in, which puts Randy in the  hot rod with
Robin and Marcus  Aurelius; As the guest, Randy gets the reclining passenger
seat, the best bed in the  house, and M.A. curls up on  the back  seat while
Robin,  the youngest, sleeps behind the  steering wheel. For about the first
thirty  seconds  after the  dome light has gone off  and  the  Shaftoes have
finished saying their  prayers out loud, Randy lies there feeling the Impala
rock on  its  suspension from the wake blasts of passing long haul semis and
feels considerably  more alienated  than he did while trying to sleep in the
jeepney  in the  jungle town in  northern  Luzon. Then he opens his eyes and
it's morning, and Robin's out there doing one handed pushups in the dust.
     "When  we get there," Robin pants, after he's finished,  "do you s'pose
you could show me  that video on  the  Internet thing  you  were telling  me
about?" He asks it with all due boyishness. Then  suddenly he looks  abashed
and adds, "Unless it's like real expensive or something."
     "It's  free.  I'll  show  it  to  you,"  Randy  says.  "Let's  get some
breakfast."  It goes  without saying that McDonald's  and  their  ilk charge
scandalously more for, e.g.,  a dish of  hash browns than  one would pay for
the equivalent mass of potatoes in raw form at (if you think money grows  on
trees) Safeway or (if you have any kind of decent  regard for the value of a
buck) farmer's markets situated at lonely interchanges in the boon docks. So
for breakfast they  must drive to a small town (grocery stores in big places
like Redding  being a tipoff) and find an actual grocery  store (convenience
stores being etc., etc., etc.) and purchase  breakfast in the most elemental
form  conceivable (deeply discounted well past their prime  bananas that are
not even in a bunch but swept up from the floor, or something,  and gathered
together in a gaily printed paper sack, and generic Cheerio knockoffs  in  a
tubular  bag, and  a  box  of  generic  powdered  milk) and eat it  from tin
military surplus  messkits that the Shaftoes produce with admirable coolness
from the hot rod's trunk, a ferrous, oily chasm all a bang with tire chains,
battered  ammo boxes, and, unless Randy's  eyes are playing tricks on him, a
pair of samurai swords.
     Anyway, this  is all  done pretty nonchalantly,  and  not like they are
trying to test Randy's mettle or anything, and so he doesn't imagine that it
qualifies  as  a true  bonding  experience.  If, hypothetically, the  Impala
throws a rod in the desert  and they have to fix it with parts stolen from a
nearby junkyard  guarded  by rabid dogs and  shotgun  packing  gypsies, that
would be a bonding experience. But Randy's wrong. On Day 2 the Shaftoes (the
male ones anyway) open up to him a bit.
     It seems (and this is abstracted from many  hours of conversation) that
when you are an able bodied young male Shaftoe  and you are  a stranger in a
strange land with  a car that you  have,  with  plenty  of advice  and elbow
grease from  your extended  family, fixed  up  pretty  nicely, the  idea  of
<I>parking it</I> in favor  of some  other mode of  conveyance  is, in addition  to
obvious financial folly, some kind of moral failure, pure and simple. That's
why  they are driving to Whitman, Washington. But  why  (one of them finally
summons  the boldness  to inquire) why are  they taking  two cars?  There is
plenty of room in the Impala for four.  Randy has gotten the sense all along
that the Shaftoes are dismayed by Randy's insistence on taking the redundant
and repulsively scarred Acura, and that only their formidable politeness has
prevented them from pointing out the  sheer madness of it. "I do not imagine
that we will stay together  beyond Whitman," Randy says (after  being around
these guys  for a couple of days  he has  begun to fall  out of the habit of
using  contractions  those  tawdry  shortcuts  of  the  verbally  lazy   and
pathologically  rushed).  "If  we have two cars,  we  can split up  at  that
point."
     "The drive is not that far, Randall," says Robin, slapping the Impala's
gas  pedal against the  floor to rip the transmission into passing gear, and
careening  around  a  gasoline  tanker.  From  the  initial  "Sir"  and "Mr.
Waterhouse," Randy  has been able to talk  them down  into addressing him by
his  first  name,  but  they  have  agreed  to  it  only  on  the  condition
(apparently) that  they use  the full  "Randall"  instead of  "Randy." Early
attempts to use "Randall Lawrence" as a compromise were vigorously denounced
by Randy, and so "Randall" it is for now. "M.A. and I would be happy to drop
you back off at  the San Francisco Airport or, uh, wherever  you  elected to
park your Acura."
     "Where else would I park it?" Randy says, not getting this last bit.
     "Well, I mean that you could probably find a place where you could park
it free  of charge for  a few days, if you did some looking around. Assuming
you  wanted  to keep it." He adds encouragingly, "That Acura probably  would
have some decent resale value even considering all the body work it needs."
     Only at this point does Randy figure out that the Shaftoes believe  him
to be utterly destitute, helpless, and  adrift  in  the wide  world. A total
charity  case.  He recalls,  now,  seeing  them  discard  a  whole  sack  of
McDonald's  wrappers when  they arrived at  his house. This whole  austerity
binge has been concocted to avoid putting financial pressure on Randy.
     Robin and M.A. have been observing him  carefully, talking  about  him,
thinking  about him. They happen to  have made some faulty assumptions,  and
come  to some wrong  conclusions,  but all  the  same, they have shown  more
sophistication than Randy was giving them  credit for.  This causes Randy to
go back and review the conversations he has had with them the last couple of
days, just to get some idea of what <I>other</I> interesting and complicated things
might have been going on in their heads. M.A. is a pretty straightforward by
the book type, the kind who'll get good grades and fit well into any kind of
hierarchical organization. Robin, on the other hand, is more of a wild card.
He has the makings of either  a total loser or a successful entrepreneur, or
maybe one of those  guys who will  oscillate  between those two poles. Randy
realizes  now,  in retrospect,  that  he  has  spilled a hell  of  a lot  of
information to  Robin, in just  a couple  of  days,  about the  Internet and
electronic money and  digital currency  and the new  global economy. Randy's
mental  state is such that he is prone to babbling aimlessly for hours at  a
time. Robin has hoovered it all up.
     To Randy it's just been aimless ventilating. He hasn't even considered,
until  now, what effect  it has  been  exerting  on the  trajectory of Robin
Shaftoe's  life.  Randall Lawrence  Waterhouse hates  <I>Star Trek</I>  and  avoids
people who don't hate it, but  even  so he has seen just about every episode
of the  damn thing,  and  he  feels,  at  this moment, like  the  Federation
scientist who beams down to a primitive planet  and thoughtlessly teaches an
opportunistic pre  Enlightenment yahoo how to construct a phaser cannon from
commonly available materials.
     Randy still has <I>some</I> money. He cannot begin to  guess how he can convey
this fact to these guys without  committing some grievous protocol error, so
the next time they stop for gas, he asks Amy to convey it to them. He thinks
(based on  his hazy understanding of the rotation system) that it's his turn
to be alone in a car with Amy, but if Amy is going to convey this data about
the money  to  one of the boys, she'll need to spend the next leg with  him,
because it must be conveyed indirectly, which will take a while, and because
of that indirectness, time will then need  to be allotted for it to sink in.
But three hours  later,  then,  at  the  gas stop  after  that, it naturally
follows that M.A. and Robin must be placed together in the same car, so that
Robin (who now  knows and understands, and who gets out of the Impala with a
big grin on his face and punches Randy affably on the shoulder) can pass the
message on to M.A., whose recent conversational gambits vis &agrave; vis Randy made
no sense at all until Randy figured out that they thought of him as a beggar
and that M.A. was trying in a really oblique way to find out if Randy needed
to share any of M.A.'s personal toiletry items.  At any rate, Randy and  Amy
get into the  Acura and they head north into Oregon, trying to keep up  with
the hot rod.
     "Well, it's nice to have a chance to spend some  time  with you," Randy
says.  His  back  is  still a bit  sore  from  where Amy  struck him  whilst
asserting,  the other morning, that expressing one's feelings was  "the name
of  the game."  So he figures he will express those  aspects of his feelings
least likely to get him in serious trouble.
     "Ah  figgered you  'n' ah'ud  have plenny a tahm to  chew the rag," Amy
says, having  reverted  utterly to  the tongue  of her ancestors in the last
couple of days. "But it has been ages  and ages since I saw  those two boys,
and you've never seen 'em at all."
     "Ages and ages? Really?"
     "Yeah."
     "How long?"
     "Well, last time  I saw Robin he  was just start
