“Bless my thermometer!”
gasped Mr. Damon. “This is terrible!”
The airship was plunging and swaying about in the awful
gale. “Can’t something be done, Tom?”
“What has happened?” cried
Mr. Nestor. “We were on a level keel before.
What is it?”
“It’s the automatic balancing
rudder!” answered Tom. “Something
has happened to it. The wind may have broken it!
Come on, Ned!” and he led the way to the engine
room.
“What are you going to do?
Don’t you want Koku to shift the deflecting
rudder? Here he is,” Ned added, as the giant
came forward, in response to a signal bell that Tom’s
chum had rung.
“It’s too late to try
the deflecting rudder!” tried Tom. “I
must see what is the matter with our balancer.”
As he spoke the ship gave a terrific plunge, and the
occupants were thrown sideways. The next moment
it was on a level keel again, scudding along with
the gale, but there was no telling when the craft
would again nearly capsize.
Tom looked at the mechanism controlling
the equalizing and equilibrium rudder. It was
out of order, and he guessed that the terrific wind
was responsible for it.
“What can we do?” cried
Ned, as the airship nearly rolled over. “Can’t
we do anything, Tom?”
“Yes. I’m going to
try. Keep calm now. We may come out all
right. This is the worst blow we’ve been
in since we were in Russia. Start the gas machine
full blast. I want all the vapor I can get.”
As I have explained the Flyer was
a combined dirigible balloon and aeroplane. It
could be used as either, or both, in combination.
At present the gas bag was not fully inflated, and
Tom had been sending his craft along as an aeroplane.
“What are you going to do?”
cried Ned, as he pulled over the lever that set the
gas generating machine in operation.
“I’m going up as high
as I can go!” cried Tom. “If we can’t
go down we must go up. I’ll get above the
hurricane instead of below it. Give me all the
gas you can, Ned!”
The vapor hissed as it rushed into
the big bag overhead. Tom carried aboard his
craft the chemicals needed to generate the powerful
lifting gas, of which he alone had the secret.
It was more powerful than hydrogen, and simple to
make. The balloon of the Flyer was now being
distended.
Meanwhile Tom, with Koku, Mr. Damon
and Mr. Nestor to help him, worked over the deflecting
rudder, and also on the equilibrium mechanism.
But they could not get either to operate.
Ned stood by the gas machine, and
worked it to the limit. But even with all that
energy, so powerful was the wind, that the Flyer rose
slowly, the gale actually holding her down as a water-logged
craft is held below the waves. Ordinarily, with
the gas machine set at its limit the craft would have
shot up rapidly.
At times the airship would skim along
on the level, and again it would be pitched and tossed
about, until it was all the occupants could do to
keep their feet. Mr. Damon was continually blessing
everything he could remember.
“Now she’s going!”
suddenly cried Ned, as he looked at the dials registering
the pressure of the gas, and showing the height of
the airship above the earth.
“Going how?” gasped Tom,
as he looked over from where he was working at the
equilibrium apparatus. “Going down?”
“Going up!” shouted Ned.
“I guess we’ll be all right soon!”
It was true. Now that the bag
was filled with the powerful lifting gas, under pressure,
the Flyer was beginning to get out of the dangerous
predicament into which the gale had blown her, Up
and up she went, and every foot she climbed the power
of the wind became less.
“Maybe it all happened for the
best,” said Tom, as he noted the height gage.
“If we had gone down, the wind might have been
worse nearer the earth.”
Later they learned that this was so.
The most destructive wind storm ever known swept across
the southern part of Europe, over which they were
flying that night, and, had the airship gone down,
she would probably have been destroyed. But, going
up, she got above the wind-strata. Up and up
she climbed, until, when three miles above the earth,
she was in a calm zone. It was rather hard to
breathe at this height, and Tom set the oxygen apparatus
at work.
This created in the interior of the
craft an atmosphere almost like that on the earth,
and the travelers were made more at their ease.
Getting out of the terrible wind pressure made it possible
to work the deflecting rudder, though Tom had no idea
of going down, as long as the blow lasted.
“We’ll just sail along
at this height until morning,” he said, “and
by then the gale may be over, or we may be beyond the
zone of it. Start the propellers, Ned. I
think I can manage to repair the equilibrium rudder
now.”
The propellers, which gave the forward
motion to the airship, had been stopped when it was
found that the wind was carrying her along, but they
were now put in motion again, sending the Flyer forward.
In a short time Tom had the equilibrium machine in
order, and matters were now normal again.
“But that was a strenuous time
while it lasted,” remarked the young inventor,
as he sat down.
“It sure was,” agreed Ned.
“Bless my pen wiper!”
cried Mr. Damon. “That was one of the few
times when I wish I’d never come with you, Tom
Swift,” and everyone laughed at that.
The Flyer was now out of danger, going
along high in the air through the night, while the
gale raged below her. At Tom’s suggestion,
Koku got a lunch ready, for they were all tired with
their labors, and somewhat nervous from the danger
and excitement.
“And now for sleep!” exclaimed
Tom, as he pushed back his plate. “Ned,
set the automatic steering gear, and we’ll see
where we bring up by morning.”
An examination, through a powerful
telescope in the bright light of morning, showed the
travelers that they were over the outskirts of a large
city, which, later, they learned was Rome, Italy.
“We’ve made a good trip,”
said Tom. “The gale had us worried, but
it sent us along at a lively clip. Now for Switzerland,
and the avalanches!”
They made a landing at a village just
outside the “Holy City,” as Rome is often
called, and renewed their supply of gasolene.
Naturally they attracted a crowd of curious persons,
many of whom had never seen an airship before.
Certainly few of them had ever seen one like Tom Swift’s.
The next day found them hovering over
the Alps, where Tom hoped to be able to get the pictures
of snow slides. They went down to earth at a
town near one of the big mountain ranges, and there
made inquiries as to where would be the best location
to look for big avalanches. If they went but
a few miles to the north, they were told, they would
be in the desired region, and they departed for that
vicinity.
“And now we’ve just got
to take our time, and wait for an avalanche to happen,”
remarked Tom, as they were flying along over the mountain
ranges. “As Mr. Damon said, these things
aren’t made to order. They just happen.”
For three days they sailed in and
out over the great snow-covered peaks of the Alps.
They did not go high up, for they wanted to be near
earth when an avalanche would occur, so that near-view
pictures could be secured. Occasionally they saw
parties of mountain climbers ascending some celebrated
peak, and for want of something better to photograph,
Tom “snapped” the tourists.
“Well, I guess they’re
all out of avalanches this season,” remarked
Ned one afternoon, when they had circled back and forth
over a mountain where, so it was said, the big snow
slides were frequent.
“It does seem so,” agreed
Tom. “Still, we’re in no hurry.
It is easier to be up here, than it is walking around
in a jungle, not knowing what minute a tiger may jump
out at you.”
“Bless my rubbers, yes!” agreed Mr. Damon.
The sky was covered with lowering
clouds, and there were occasionally flurries of snow.
Tom’s airship was well above the snow line on
the mountains. The young inventor and Ned sat
in the pilot house, taking observations through a
spyglass of the mountain chain below them.
Suddenly Ned, who had the glass focused
on a mighty peak, cried out:
“There she is, Tom!”
“What?”
“The avalanche! The snow
is beginning to slide down the mountain! Say,
it’s going to be a big one, too. Got your
camera ready?”
“Sure! I’ve had it
ready for the last three days. Put me over there,
Ned. You look after the airship, and I’ll
take the pictures!”
Tom sprang to get his apparatus, while
his chum hurried to the levers, wheels and handles
that controlled the Flyer. As they approached
the avalanche they could see the great mass of ice,
snow, big stones, and earth sliding down the mountain
side, carrying tall trees with it.
“This is just what I wanted!”
cried Tom, as he set his camera working. “Put
me closer, Ned.”
Ned obeyed, and the airship was now
hovering directly over the avalanche, and right in
its path. The big landslide, as it would have
been called in this country, met no village in its
path, fortunately, or it would have wiped it out completely.
It was in a wild and desolate region that it occurred.
“I want to get a real close
view!” cried Tom, as he got some pictures showing
a whole grove of giant trees uprooted and carried
off. “Get closer Ned, and—”
Tom was interrupted by a cry of alarm from his chum.
“We’re falling!”
yelled Ned. “Something has gone wrong.
We’re going down into the avalanche!”.
