IN THE JUNGLE
“What will we do with the cameras,
Blake? The films, too, they will all be spoiled—we
haven’t enough waterproof cases!” cried
Joe to his chum, as the boat, through some accident
or failure, backed nearer and nearer to the closing
steel gates.
“Will we really have to jump
overboard?” asked the Spaniard. “I
am not a very excellent swimmer.”
But Blake, at whom these questions
seemed directed, did not have to answer them.
For, after a series of confused shouts on the top
of the concrete wall above them the movement of the
boat, as well as the slow motion of the lock gates,
ceased. It was just in time, for the rudder of
the tug was not more than a few feet away from the
jaws of steel.
“You’re all right now,”
a man called down to those on the tug, from the wall
over their heads. “Something went wrong
with the towing locomotives. There’s no
more danger.”
“Well, I’m glad to know
that,” answered Captain Watson gruffly.
“You might just as well kill a man as scare him
to death. What was the matter, anyhow?”
“Well, all of our machinery
isn’t working as smoothly as we’ll have
it later,” the canal engineer explained.
“Some of our signals went wrong as you were
being towed through, and you went backward instead
of forward. Then it took a minute or so to stop
the lock gates. But you’re all right now,
and you’ll go on through.”
Blake and Joe looked at each other
and smiled in relief, and Mr. Alcando appeared to
breathe easier. A little later the tug was again
urged forward toward the front lock gates. Then
the closing of those at her stern went on, until the
vessel was in a square steel and concrete basin—or,
rather, a rectangular one, for it was longer than
it was wide, to lend itself to the shape of the vessels.
As Blake had said, it was like a big swimming tank.
“Now we’ll go up,”
Captain Watson said. “You can’t get
any pictures in here, I suppose?” he added.
“We can show the water bubbling
up as it fills the lock,” said Blake. “Water
always makes a pretty scene in moving pictures, as
it seems to move at just the right rate of speed.
We’ll take a short strip of film, Joe, I guess.”
The tug did not occupy a whole section
of the lock, for they are built to accommodate vessels
a thousand feet long. To economize time in filling
up such a great tank as that would be the locks are
subdivided by gates into small tanks for small vessels.
“It takes just forty-six gates
for all the locks,” explained Captain Watson,
while Blake and Joe were getting their camera in position,
and the men at the locks were closing certain water
valves and opening others. “Each lock has
two leaves, or gates, and their weight runs anywhere
from three hundred to six hundred tons, according
to its position. Some of the gates are forty-seven
feet high, and others nearly twice that, and each leaf
is sixty-five feet wide, and seven feet thick.”
“Think of being crushed between
two steel gates, of six hundred tons each, eighty
feet high, sixty-five feet wide and seven feet thick,”
observed Joe.
“I don’t want to think
of it!” laughed Blake. “We are well
out of that,” and he glanced back toward the
closed and water-tight lock gates which had so nearly
nipped the tug.
“Here comes the water!”
cried the captain. There was a hissing and gurgling
sound, and millions of bubbles began to show on the
surface of the limpid fluid in which floated the Nama.
The water came in from below, through the seventy
openings in the floor of each lock, being admitted
by means of pipes and culverts from the upper level.
As the water hissed, boiled and bubbled
while it flowed in Blake took moving pictures of it.
Slowly the Nama rose. Higher and higher
she went until finally she was raised as high as that
section of the lock would lift her. She went up
at the rate of two feet a minute, though Captain Watson
explained that when there was need of hurry the rate
could be three feet a minute.
“And we have two more locks
to go through?” asked Joe.
“Yes, two more here at Gatun,
and three at Miraflores; or, rather, there is one
lock at Pedro Miguel, where we go down thirty and a
third feet, and then we go a mile to reach the locks
at Miraflores.
“There we shall have to go through
two locks, with a total drop of fifty-four and two-thirds
feet,” Captain Watson explained. “The
system is the same at each place.”
The tug was now resting easily in
the basin, but some feet above the sea level.
Blake and Joe had taken enough moving pictures of
this phase of the Canal, since the next scenes would
be but a repetition of the process in the following
two locks that would lift the Nama to the level
of Gatun Lake.
“But I tell you what we could
do,” Blake said to his chum.
“What’s that—swim
the rest of the way,” asked Joe, “and have
Mr. Alcando make pictures of us?”
“No, we’ve had enough
of water lately. But we could get out on top
of the lock walls, and take pictures of the tug going
through the lock. That would be different.”
“So it would!” cried Joe. “We’ll
do it!”
They easily obtained permission to
do this, and soon, with their cameras, and accompanied
by Mr. Alcando, they were on the concrete wall.
From that vantage point they watched the opening of
the lock gates, which admitted the Nama into
the next basin. There she was shut up, by the
closing of the gates behind her, and raised to the
second level. The boys succeeded in getting some
good pictures at this point and others, also, when
the tug was released from the third or final lock,
and steamed out into Gatun Lake. There was now
before her thirty-two miles of clear water before reaching
Miraflores.
“Better come aboard, boys,”
advised Captain Watson, “and I’ll take
you around to Gatun Dam. You’ll want views
of that.”
“We sure will!” cried Blake.
“Isn’t it all wonderful!”
exclaimed Joe, who was deeply impressed by all he
saw.
“It is, indeed!” agreed
the Spaniard. “Your nation is a powerful
and great one. It is a tremendous achievement.”
Aboard the tug they went around toward
the great dam that is really the key to the Panama
Canal. For without this dam there would be no
Gatun Lake, which holds back the waters of the Chagres
River, making a big lake eighty-five feet above the
level of the ocean. It is this lake that makes
possible the operation of a lock canal. Otherwise
there would have to be a sea-level one, and probably
you boys remember what a discussion there was, in
Congress and elsewhere, about the advantages and disadvantages
of a sea-level route across the Isthmus.
But the lock canal was decided on,
and, had it not been, it is probable that the Canal
would be in process of making for many years yet to
come, instead of being finished now.
“Whew!” whistled Joe,
as they came in sight of the dam. “That
sure is going some!”
“That’s what it is!”
cried Captain Watson, proudly, for he had had a small
part in the work. “It’s a mile and
a half long, half a mile thick at the base, three
hundred feet through at the waterline, and on top
a third of that.”
“How high is it?” asked
Joe, who always liked to know just how big or how
little an object was. He had a great head for
figures.
“It’s one hundred and
five feet high,” the captain informed him, “and
it contains enough concrete so that if it were loaded
into two-horse wagons it would make a procession over
three times around the earth.”
“Catch me! I’m going
to faint!” cried Blake, staggered at the immensity
of the figure.
“That dam is indeed the key
to the whole lock,” murmured Mr. Alcando, as
he looked at the wonderful piece of engineering.
“If it were to break—the Canal would
be ruined.”
“Yes, ruined, or at least destroyed
for many years,” said Captain Watson solemnly.
“But it is impossible for the dam to break of
itself. No waters that could come into the lake
could tear it away, for every provision has been made
for floods. They would be harmless.”
“What about an earthquake?”
asked Joe. “I’ve read that the engineers
feared them.”
“They don’t now,”
said the captain. “There was some talk,
at first, of an earthquake, or a volcanic eruption,
destroying the dam, but Panama has not been visited
by a destructive earthquake in so long that the danger
need not be considered. And there are no volcanoes
near enough to do any harm. It is true, there
might be a slight earthquake shock, but the dam would
stand that. The only thing that might endanger
it would be a blast of dynamite.”
“Dynamite!” quickly exclaimed
Mr. Alcando. “And who would dare to explode
dynamite at the dam?”
“I don’t know who would
do it, but some of the enemies of the United States
might. Or someone who fancied the Canal had damaged
him,” the captain went on.
“And who would that be?” asked Blake in
a low tone.
“Oh, someone, or some firm,
who might fancy that the Canal took business away
from them. It will greatly shorten certain traffic
and trade routes, you know.”
“Hardly enough to cause anyone
to commit such a crime as that, do you think?”
asked the Spaniard.
“That is hard to answer,”
went on the tug commander. “I know that
we are taking great precautions, though, to prevent
the dam, or the locks, from being damaged. Uncle
Sam is taking no chances. Well, have you pictures
enough?”
“I think so,” answered
Blake. “When we come back we’ll stop
off here and get some views from below the dam, showing
the spillway.”
“Yes, that ought to be interesting,”
the captain agreed.
The tug now steamed on her way out
into Gatun Lake, and there a series of excellent views
were obtained for the moving picture cameras.
Mr. Alcando was allowed to do his part. He was
rapidly learning what the boys could teach him.
“Of course it could never happen,”
the Spaniard said, when the cameras had been put away,
for the views to be obtained then were of too much
sameness to attract Joe or Blake, “it would never
happen, and I hope it never does; but if it did it
would make a wonderful picture; would it not?”
he asked.
“What are you talking about?” asked Blake.
“The Gatun Dam,” was the
answer. “If ever it was blown up by dynamite
it would make a wonderful scene.”
“Too wonderful,” said
Joe grimly. “It would be a terrible crime
against civilization to destroy this great canal.”
“Yes, it would be a great crime,”
agreed the Spaniard in a low voice. A little
later he went to his stateroom on the tug, and Blake
and Joe remained on deck.
“Queer sort of a chap; isn’t he?”
said Joe.
“He sure is—rather deep,” agreed
his chum.
“Are you boys going into the
jungle?” asked the tug captain that afternoon.
“Yes, we want to get a few views
showing life in the woods,” answered Blake.
“Why?”
“Well, the reason I asked is
that I can take you to the mouth of the Chagres River
and from there you won’t have so much trouble
penetrating into the interior. So if you’re
going—”
“I think we had better go; don’t
you?” asked Blake of his chum.
“Surely, yes. We might
get some fine pictures. They’ll go well
with the Canal, anyhow; really a sort of part of the
series we’re taking.”
“All right, then, I’ll
leave you in the jungle,” the captain said.
A day or so later, stops having been
made to permit the boys to film certain scenes they
wanted, the tug reached Gamboa, where they stopped,
to plan a trip into the interior.
Then, one morning, with their cameras
loaded with film, they started off for a brief trip
into the jungle.
