<h2 id="c6"><br/><i>DANGER ON THE ICE CANAL</i></h2>
<p>Steve and Sue Shannon were at
Mars Port No. 13. This was one of the many
colonies on the planet Mars where Earth
scientists were carrying on work. It was a town
of plastic tops, called domes, that were clear
as glass. The town was at the center of three
canals that led outward into the red desert.</p>
<div class="pb" id="Page_84">84</div>
<p>The Shannon twins were now touring the
largest dome with Biff Warren, who worked
for their father’s space cargo company. Suddenly
their tour brought them to a large cafeteria
where many of the workers were eating.</p>
<p>“Umm!” Sue exclaimed. “Smell that turkey!”</p>
<p>“Yeah!” Steve said. “It sure makes your
mouth water, doesn’t it?”</p>
<p>“Which reminds me,” Biff said, looking at
his watch. “We’ll have to finish up our sightseeing
pretty soon. The quicker we get back to
your father’s ship, the quicker we can have
our own turkey feast!”</p>
<p>“I can hardly wait for that!” Sue sighed, as
the wonderful smell of the holiday meal kept
tickling her nose.</p>
<p>When Thanksgiving dinner was finished
aboard the big space freighter that had brought
the children to Mars, the ship would take off
into space. But before that, Biff, Sue and Steve
would have to go twenty miles back down the
ice canal to reach the ship.</p>
<div class="pb" id="Page_85">85</div>
<p>Biff had become a close friend of the young
Shannons, having made trips with them to
other ports in space. Sue liked Biff because of
his quick smile and gentle patience. Steve
liked him because he was all that Steve would
like to be some day himself—a fearless, bold
spaceman.</p>
<p>They finished up their tour of the dome.
They saw the room where giant machines
made oxygen out of chemicals and blew it
through the building so that there was fresh
air to breathe all the time. And they saw the
astronomy hall far up on top of the dome
where scientists could see the heavens through
the thin atmosphere much clearer than they
could from Earth.</p>
<p>“Isn’t it about time for the fuel rocket to
be shot off, Biff?” Steve asked.</p>
<p>Biff nodded. “I think it’s just about time,”
he said. “We’ll suit up and go outside to see.”</p>
<div class="pb" id="Page_86">86</div>
<p>In the dressing room they put on their space
suits. As though they were his own children,
Biff carefully checked the young Shannons’ air
tanks, built-in heaters, and their helmet radios
for talking to one another. Finally Biff rubbed
gelatin on their helmets so that they would
not frost over in the cold that was a hundred
degrees below zero.</p>
<p>Outside they found space-suited figures
gathered around the fuel rocket cannon. The
cannon was pointed toward a shiny ball high
up in the purple-black sky.</p>
<p>“Look, Sis, there’s the space ship toward
which they’re going to shoot the fuel rocket,”
Steve said.</p>
<p>“I see it!” Sue cried, her eyes dancing excitedly.</p>
<p>“They have to line up the cannon with the
ship just right or the rocket won’t reach it,”
Biff said.</p>
<p>“Won’t the rocket hit the ship?” Steve asked.</p>
<p>“No, it’ll lose all its speed by the time it
reaches the ship,” Biff told him. “Then they’ll
take on fuel from the rocket by means of a
long hose.”</p>
<div class="pb" id="Page_87">87</div>
<p>Suddenly the three of them heard a loud
roar and saw a burst of flame. Like a bullet,
the rocket left the muzzle of the giant gun and
rose into the sky.</p>
<p>“They’ll be shooting off more rockets before
they have enough fuel for the space ship,” Biff
said. “There’ll be a little wait in between each
firing.”</p>
<p>“Look, Biff, isn’t the space ship right over
the canal where we’ll be heading back?” Steve
asked.</p>
<p>“That’s right, Steve,” Biff answered. “You’ll
remember, our ship is at the end of the canal.
We’ll be able to see the rockets go off as we
head back—which we’d better do right now, if
we’re going to have any turkey and pumpkin
pie!”</p>
<div class="pb" id="Page_88">88</div>
<p>The canals of Mars had been carved out of
a great desert by water and fierce winds. Because
of the ice that filled them, they made
good highways. The three went to the canal
bank to see if their sled was ready to go, and
it was. The sled looked like a big bombing
plane with the wings off. Instead of wheels,
there were long runners beneath it. In this
sled Biff and his young helpers had brought
supplies to the colony several hours before.</p>
<p>Steve, Sue and Biff climbed into the front
seat. Then Biff shut the door. He pushed buttons
in front of them. Steve and Sue felt the
sled’s engines throbbing. The next moment
the sled shot off over the smooth sheet of ice,
Biff holding tightly to the steering wheel.</p>
<p>“Wheeeeee!” Sue screamed in delight.
“Offffffffff weeeeeeee goooooooooo!”</p>
<p>“Like a rooooller cooooster!” Steve shouted.</p>
<p>They sped along at a hundred miles an hour.
This was as much fun as they had had on their
last space journey.</p>
<p>Each of their trips into space seemed to be
more exciting than the last. They had won a
lifetime free pass into space and by now they
were sure they would need a lifetime in which
to see all of its many wonders. A brave act by
Steve on their first space trip had earned them
their pass. Right now, Steve thought that their
mother and home, back in Arkansas, seemed
as far away as Deneb, the North Star of Mars.</p>
<div class="pb" id="Page_89">89</div>
<p>“We’ll be there in about ten minutes,” Biff
said. “The ship leaves in thirty, which gives
us some spare time.”</p>
<p>“Look,” Sue said, “there comes the first fuel
rocket back down in a parachute.”</p>
<p>“That’s right, Sue,” Biff replied.</p>
<p>Steve studied the bank of the canal. Along it
he saw scrubby cactus, which was forever fighting
for life in the cold, dry atmosphere. Beyond
the bank stretched acres of red wasteland,
and sand drifts piled up by strong winds that
never stopped blowing.</p>
<p>A few minutes later, Sue noticed a bright
streak against the purple sky. It was nearly as
bright as the tiny sun, which was so far away
that it could not keep Mars warm.</p>
<p>“There goes another fuel rocket!” Sue
called out, pointing through the windshield.</p>
<p>As Biff caught sight of it, he jerked up
sharply in his seat, bumping the shoulders of
Sue and Steve on both sides of him.</p>
<div class="pb" id="Page_90">90</div>
<p>“That rocket’s too low!” he exclaimed. “It’s
not lifting! Something’s gone wrong!”</p>
<p>Steve felt chills run up his spine. He was
seeing the danger too, now. The rocket was
dropping ahead of them, a screaming bomb
filled with explosive fuel. It was still quite a
distance away, but even Steve knew that it
would make a terrible blast when it struck the
ice.</p>
<p>Biff’s feet hit the brakes of the sled and the
runners chewed into the hard ice pack, shrieking,
and bringing the sled to a skidding stop.
The riders were slammed forward. Sue and
Steve were dazed, but not hurt. When Steve’s
mind cleared, he saw that Biff had thrown himself
over in front of Sue and him to protect
them. But in doing this, his helmet had
thumped against the windshield. He was now
slumped over and not moving.</p>
<p>“Sue!” Steve cried. “Biff is hurt!”</p>
<div class="pb" id="Page_91">91</div>
<p>Just then they felt the shock of the explosion.
It tilted the sled at an angle and dropped
it down again with a hard jolt. The air was
filled with flying chunks of ice. It looked like
a hailstorm outside. The ice clattered against
the windshield like stones. Sue and Steve were
relieved when it finally stopped. But the explosion
had left the ice sheet in front of them
broken and choked with lumps of ice.</p>
<p>“Steve,” Sue moaned, “what are we going
to do?”</p>
<p>Steve looked at Biff who was still not moving.
He could see a big lump on Biff’s forehead
where his head had struck the helmet,
knocking him out. The children tried to revive
their friend, but could not.</p>
<p>“We’ve got to get the sled to the ship ourselves,
Sue!” her brother said. “Biff may need
a doctor! Besides, I bet we’ve all missed our
Thanksgiving dinner!”</p>
<p>“I won’t want any dinner if Biff is hurt
badly!” Sue said tearfully.</p>
<div class="pb" id="Page_92">92</div>
<p>At first it seemed like an impossible thing
for a pair of twelve-year-olds to run the big
sled. But Steve remembered how Biff had
worked the controls and he believed he, too,
could do it. He changed seats with the unconscious
spaceman and tried the levers and
buttons.</p>
<p>Presently the sled’s rockets began to pour
fire out of the rear. But Steve couldn’t get the
sled to move. He was afraid it had been damaged.
Then Sue showed him a lever to push
which she had remembered seeing Biff shove.
As Steve worked it gently, the sled started off
slowly.</p>
<p>“We’ll go slow,” Steve said, “and take it
very easy.”</p>
<p>The explosion had hit at the far edge of the
canal so that there was a narrow place on the
other side where the ice was still smooth. Steve
carefully guided the sled across the canal and
through the unbroken part. When there was
smooth ice before them, Steve picked up speed
a little. As he drove, Sue tried to awaken Biff.</p>
<div class="pb" id="Page_93">93</div>
<p>Steve would have found their adventure a
lot of fun if things weren’t so serious at the moment.
It wasn’t every day that a boy had the
chance to drive a giant rocket sled on a distant
planet!</p>
<p>At last Steve saw the round top of the space
ship just over the horizon. It was at that moment
that Sue called out the good news:</p>
<p>“Biff’s awakening, Steve!”</p>
<p>The boy saw their friend slowly rise up,
then shake his head to clear it. When he
smiled at them in his pleasant way, they were
sure that he was going to be all right. By the
time they had told him what had happened,
he was his old self again. He took the controls
and looked at his watch.</p>
<p>“Time’s running out,” he said. “We’ve got
to hit top speed again. Hold onto your helmets!
Here we go!”</p>
<p>And off they went at lightning speed once
more. It seemed to Steve as if they covered
the distance between them and the space ship
in seconds.</p>
<div class="pb" id="Page_94">94</div>
<p>As the sled came to a gentle stop beneath
the giant freighter, Biff said, “It looks like we’ll
make our Thanksgiving dinner on time after
all, doesn’t it, kids?”</p>
<p>“Yeah,” Steve answered, “and this is certainly
one Thanksgiving that I’m really thankful!”</p>
<p>“I know what you mean, Steve,” Sue said
thoughtfully. “We’re thankful that we’re
alive!”</p>
<p>Biff and Steve both nodded. It was a holiday
none of them would ever forget.</p>
