<h3>Martian</h3>
<p>It was night when Feldman came to, and the temperature
was dropping rapidly. He struggled to sit up
through a fog of pain. Somewhere in his bag, he should
have an anodyne tablet that would kill any ache. He
finally found the pill and swallowed it, fumbling with
the aspirator lip opening.</p>
<p>The aspirator meant life to him now, he suddenly realized.
He twisted to stare at the tiny charge-indicator
for the battery. It showed half-charge. Then he saw that
someone had attached another battery beside it. He puzzled
briefly over it, but his immediate concern was for
shelter.</p>
<p>Apparently he was still where he had been knocked
out. There was a light coming from the little station,
and he headed toward that, fumbling for the few quarters
that represented his entire fortune.</p>
<p>Maybe it would have been better if the tubemen had
killed him. Batteries were an absolute necessity here,
food and shelter would be expensive, and he had no
skills to earn his way. At most, he had only a day or so
left. But meantime, he had to find warmth before the
cold killed him.</p>
<p>The tiny restaurant in the station was still open, and
the air was warm inside. He pulled off the aspirator,
shutting off the battery.</p>
<p>The counterman didn't even glance up as he entered.
Feldman gazed at the printed menu and flinched.<span class="pagenum"><SPAN name="Page_29" id="Page_29"></SPAN></span></p>
<p>"Soup," he ordered. It was the cheapest item he could
find.</p>
<p>The counterman stared at him, obviously spotting his
Earth origin. "You adjusted to synthetics?"</p>
<p>Feldman nodded. Earth operated on a mixed diet,
with synthetics for all who couldn't afford the natural
foods there. But Mars was all synthetic. Many of the
chemicals in food could exist in either of two forms, or
isomers; they were chemically alike, but differently crystallized.
Sometimes either form was digestible, but frequently
the body could use only the isomer to which it
was adjusted.</p>
<p>Martian plants produced different isomers from those
on Earth. Since the synthetic foods turned out to be
Mars-normal, that was probably the more natural form.
Research designed to let the early colonists live off native
food here had turned up an enzyme that enabled
the body to handle either isomer. In a few weeks of eating
Martian or synthetic food, the body adapted; without
more enzyme, it lost its power to handle Earth-normal
food.</p>
<p>The cheapness of <ins class="correction" title="Transcriber's Note: Original had 'snythetics'.">synthetics</ins> and the discovery that
many diseases common to Earth would not attack Mars-normal
bodies led to the wide use of synthetics on
Earth. No pariah could have been expected to afford
Earth-normal.</p>
<p>Feldman finished the soup, and found a cigarette
that was smokable. "Any objections if I sit in the waiting
room?"</p>
<p>He'd expected a rejection, but the counterman only
shrugged. The waiting room was almost dark and the
air was chilly, but there was normal pressure. He found
a bench and slumped onto it, lighting his cigarette.
He'd miss the smokes—but probably not for long. He<span class="pagenum"><SPAN name="Page_30" id="Page_30"></SPAN></span>
finished the cigarette reluctantly and sat huddled on the
bench, waiting for morning.</p>
<p>The airlock opened later, and feet sounded on the
boards of the waiting-room floor, but he didn't look up
until a thin beam of light hit him. Then he sighed and
nodded. The shoes, made of some odd fiber, didn't look
like those of a cop, but this was Mars. He could see
only a hulking shadow behind the light.</p>
<p>"You the man who was a medical doctor?" The voice
was dry and old.</p>
<p>"Yeah," Feldman answered. "Once."</p>
<p>"Good. Thought that space crewman was just lying
drunk at first. Come along, Doc."</p>
<p>"Why?" It didn't matter, but if they wanted him to
move on, they'd have to push a little harder.</p>
<p>The light swung up to show the other. He was the
shade of old leather with a bleached patch of sandy hair
and the deepest gray eyes Feldman had ever seen. It
was a face that could have belonged to a country storekeeper
in New England, with the same hint of dry humor.
The man was dressed in padded levis and a leather
jacket of unguessable age. His aspirator seemed worn
and patched, and one big hand fumbled with it.</p>
<p>"Because we're friends, Doc," the voice drawled at
him. "Because you might as well come with us as sit
here. Maybe we have a job for you."</p>
<p>Feldman shrugged and stood up. If the man was a
Lobby policeman, he was different from the usual kind.
Nothing could be worse than the present prospects.</p>
<p>They went out through the doors of the waiting room
toward a rattletrap vehicle. It looked something like a
cross between a schoolboy's jalopy and a scaled-down
army tank of former times. The treads were caterpillar
style, and the stubby body was completely enclosed. A<span class="pagenum"><SPAN name="Page_31" id="Page_31"></SPAN></span>
tiny airlock stuck out from the rear.</p>
<p>Two men were inside, both bearded. The old man
grinned at them. "Mark, Lou, meet Doc Feldman. Sit,
Doc. I'm Jake Mullens, and you might say we were
farmers."</p>
<p>The motor started with a wheeze. The tractor swung
about and began heading away from Southport toward
the desert dunes. It shook and rattled, but it seemed to
make good time.</p>
<p>"I don't know anything about farming," Feldman protested.</p>
<p>Jake shrugged. "No, of course not. Couple of our
friends heard about you where a spaceman was getting
drunk and tipped us off. We know who you are. Here,
try a bracky?"</p>
<p>Feldman took what seemed to be a cigarette and
studied it doubtfully. It was coarse and fibrous inside,
with a thin, hard shell that seemed to be a natural
growth, as if it had been chopped from some vine. He
lighted it, not knowing what to expect. Then he
coughed as the bitter, rancid smoke burned at his throat.
He started to throw it down, and hesitated. Jake was
smoking one, and it had killed the craving for tobacco
almost instantly.</p>
<p>"Some like 'em, most don't," Jake said. "They won't
hurt you. Look—see that? Old Martian ruins. Built by
some race a million years ago. Only half a dozen on
Mars."</p>
<p>It was only a clump of weathered stone buildings in
the light from the tractor, and Feldman had seen better
in the stereo shots. It was interesting only because it
connected with the legendary Martian race, like the canals
that showed from space but could not be seen on
the surface of the planet.<span class="pagenum"><SPAN name="Page_32" id="Page_32"></SPAN></span></p>
<p>Feldman waited for the other to go on, but Jake was
silent. Finally, he ground out the butt of the weed.
"Okay, Jake. What do you want with me?"</p>
<p>"Consultation, maybe. Ever hear of herb doctors? I'm
one of them."</p>
<p>Feldman knew that the Lobby permitted some leniency
here, due to the scarcity of real medical help.
There was only one decent hospital at Northport, on
the opposite side of the planet.</p>
<p>Jake sighed and reached for another bracky weed.
"Yeah, I'm pretty good with herbs. But I got a sick
village on my hands and I can't handle it. We can't all
mortgage our work to pay for a trip to Northport.
Southport's all messed up while the new she-doctor gets
her metabolism changed. Maybe the old guy there
would have helped, but he died a couple months ago.
So it looks like you're our only hope."</p>
<p>"Then you have no hope," Feldman told him sickly.
"I'm a pariah, Jake. I can't do a thing for you."</p>
<p>"We heard about your argument with the Lobby.
News reaches Mars. But these are mighty sick people,
Doc."</p>
<p>Feldman shook his head. "Better take me back. I'm
not allowed to practice medicine. The charge would be
first-degree murder if anything happened."</p>
<p>Lou leaned forward. "Shall I talk to him, Jake?"</p>
<p>The old man grimaced. "Time enough. Let him see
what we got first."</p>
<p>Sand howled against the windshield and the tractor
bumped and surged along. Feldman took another of the
weeds and tried to estimate their course. But he had no
idea where they were when the tractor finally stopped.
There was a village of small huts that seemed to be
merely entrances to living quarters dug under the sur<span class="pagenum"><SPAN name="Page_33" id="Page_33"></SPAN></span>face.
They led him into one and through a tunnel into
a large room filled with simple cots and the unhappy
sounds of sick people.</p>
<p>Two women were disconsolately trying to attend to
the half-dozen sick—four children and two adults. Their
faces brightened as they saw Jake, then fell. "Eb and
Tilda died," they reported.</p>
<p>Feldman looked at the two figures under the sheets
and whistled. The same black specks he had seen on the
face of Billings covered the skins of the two old people
who had died.</p>
<p>"Funny," Jake said slowly. "They didn't quite act like
the others and they sure died mighty fast. Darn it, I
had it figured for that stuff in the book. Infantile paralysis.
How about it, Doc? Sort of like a cold, stiff
sore neck."</p>
<p>It was clearly polio—one of the diseases that could attack
Mars-normal flesh. Feldman nodded at the symptoms,
staring at the sick kids. He shrugged, finally.
"There's a cure for it, but I don't have the serum. Neither
do you, or you wouldn't have brought me here. I
couldn't help if I wanted to."</p>
<p>"That old book didn't list a cure," Jake told him.
"But it said the kids didn't have to be crippled. There
was something about a Kenny treatment. Doc, does the
stuff really cripple for life?"</p>
<p>Feldman saw one of the boys flinch. He dropped his
eyes, remembering the Lobby's efficient spy service on
Earth and wondering what it was like here. But he knew
the outcome.</p>
<p>"Damn you, Jake!"</p>
<p>Jake chuckled. "Thought you would. We sure appreciate
it. Just tell us what to do, Doc."</p>
<p>Feldman began writing down his requirements, try<span class="pagenum"><SPAN name="Page_34" id="Page_34"></SPAN></span>ing
to remember the details of the treatment. Exercise,
hot compresses, massage. It was coming back to him.
He'd have to do it himself, of course, to get the feel
of it. He couldn't explain it well enough. But he couldn't
turn his back on the kids, either.</p>
<p>"Maybe I can help," he said doubtfully as he moved
toward a cot.</p>
<p>"No, Doc." Jake's voice wasn't amused any longer,
and he held the younger man back. "You're doing us a
favor, and I'll be darned if I'll let you stick your neck
out too far. You can't treat 'em yourself. Mars is
tougher than Earth. You should live under Space Lobby
<i>and</i> Medical Lobby here a while. Oh, maybe they
don't mind a few fools like me being herb doctors, but
they'd sure hate to have a man who can do real medicine
outside their hands. You let me do it, or get in
the tractor and I'll have Lou drive you back. Once you
start in here, there'll be no stopping. Believe me."</p>
<p>Feldman looked at him, seeing the colonials around
him for the first time as people. It had been a long time
since he'd been treated as a fellow human by anyone.</p>
<p>Jake was right, he knew. Once he put his hand to the
bandage, eventually there'd be no turning back from
the scalpel. These people needed medical help too desperately.
Eventually, the news would spread, and the
Lobby police would come for him. Chris couldn't afford
to shield him. In fact, he was sure now that she'd
hunt him night and day.</p>
<p>"Don't be a fool, Jake," he ordered brusquely. He
handed his list to one of the women. "You'll have to
learn to do what I do," he told the people there. "You'll
have to work like fools for weeks. But there won't be
many crippled children. I can promise that much!"</p>
<p>He blinked sharply at the sudden hope in their eyes.<span class="pagenum"><SPAN name="Page_35" id="Page_35"></SPAN></span>
But his mind went on wondering how long it would
be before the inevitable would catch up with him. With
luck, maybe a few months. But he hadn't been blessed
with any superabundance of luck. It would probably be
less time than he thought.<span class="pagenum"><SPAN name="Page_36" id="Page_36"></SPAN></span></p>
