ALONG THE CANAL
“Blake, did you hear that?”
asked Joe, after a pause, during which he and his
chum could hear the low buzz of conversation from the
other balcony.
“Yes, I heard it. What of it?”
“Well, nothing that I know of, and yet—”
“Yet you’re more suspicious
than I was,” broke in Blake. “I don’t
see why.”
“I hardly know myself,”
admitted Joe. “Yet, somehow, that ticking
box, and what you saw in that letter—”
“Oh, nonsense!” interrupted
Blake. “Don’t imagine too much.
You think that curious box is some attachment for
a moving picture camera; do you?”
“Well, it might be, and—”
“And you’re afraid he
will get ahead of you in your invention of a focus
tube; aren’t you?” continued Blake, not
giving his companion a chance to finish what he started
to say. For Joe had recently happened to hit
on a new idea of a focusing tube for a moving picture
camera, and had applied for a patent on it. But
there was some complication and his papers had not
yet been granted. He was in fear lest someone
would be granted a similar patent before he received
his.
“Oh, I don’t know as I’m
afraid of that,” Joe answered slowly.
“Well, it must be that—or
something,” insisted Blake. “You hear
Alcando and someone else talking about a machine, and
you at once jump to the conclusion that it’s
a camera.”
“No, I don’t!” exclaimed
Joe. He did not continue the conversation along
that line, but he was doing some hard thinking.
Later that evening, when Mr. Alcando
called at the room of the two chums to bid them goodnight,
he made no mention of his visitor on the balcony.
Nor did Blake or Joe question him.
“And we start up the Canal in
the morning?” asked the Spaniard.
“Yes, and we’ll make the
first pictures going through the Gatun locks,”
decided Blake.
“Good! I am anxious to
try my hand!” said their “pupil.”
With their baggage, valises, trunks,
cameras, boxes of undeveloped film, other boxes to
hold the exposed reels of sensitive celluloid, and
many other things, the moving picture boys and Mr.
Alcando went aboard the government tug Nama
the next morning. With the exception of some
Army engineers making a trip of inspection, they were
the only passengers.
“Well, are you all ready, boys?”
asked the captain, for he had been instructed by his
superiors to show every courtesy and attention to
our heroes. In a sense they were working for Uncle
Sam.
“All ready,” answered Blake.
“Then we’ll start,” was the reply.
“I guess—”
“Oh, one moment, I beg of you!”
cried Mr. Alcando. “I see a friend coming
with a message to me,” and he pointed along the
pier, where the tug was tied. Coming on the run
was a man who bore every appearance of being a Spaniard.
“You are late,” complained
Mr. Alcando, as the runner handed him a letter.
“You almost delayed my good friend, the captain
of this tug.”
“I could not help it,”
was the answer. “I did not receive it myself
until a few minutes ago. It came by cable.
So you are off?”
“We are off!” answered Mr. Alcando.
Then the other spoke in Spanish, and
later on Blake, who undertook the study of that language
so as to make himself understood in a few simple phrases
knew what it was that the two men said. For the
runner asked:
“You will not fail us?”
“I will not fail—if
I have to sacrifice myself,” was the answer
of Mr. Alcando, and then with a wave of his hand the
other went back up the pier.
“All right?” again asked Captain Watson.
“All right, my dear sir, I am
sorry to have delayed you,” answered Mr. Alcando
with more than his usual politeness.
“A little delay doesn’t
matter. I am at your service,” the commander
said. “Well, now we’ll start.”
If either Blake or Joe felt any surprise
over the hurried visit, at the last minute, of Mr.
Alcando’s friend, they said nothing to each
other about it. Besides, they had other matters
to think of just then, since now their real moving
picture work was about to begin.
In a short time they were moving away
from the pier, up the harbor and toward the wonderful
locks and dam that form the amazing features (aside
from the Culebra Cut) of the great Canal.
“Better get our cameras ready;
hadn’t we, Blake?” suggested Joe.
“I think so,” agreed his
chum. “Now, Mr. Alcando, if you want to
pick up any points, you can watch us. A little
later we’ll let you grind the crank yourself.”
I might explain, briefly, that moving
pictures are taken not by pressing a switch, or a
rubber bulb, such as that which works a camera shutter,
but by the continuous action of a crank, or handle,
attached to the camera. Pressing a bulb does well
enough for taking a single picture, but when a series,
on a long celluloid strip, are needed, as in the case
for the “movies,” an entirely different
arrangement becomes absolutely necessary.
The sensitive celluloid film must
move continuously, in a somewhat jerky fashion, inside
the dark light-tight camera, and behind the lens.
As each picture, showing some particular motion, is
taken, the film halts for the briefest space of time,
and then goes on, to be wound up in the box, and a
new portion brought before the lens for exposure.
All this the crank does automatically,
opening and closing the shutter, moving the film and
all that is necessary.
I wish I had space, not only to tell
you more of how moving pictures are made, but much
about the Panama Canal. As to the former—the
pictures—in other books of this series I
have done my best to give you a brief account of that
wonderful industry.
Now as to the Canal—it
is such a vast undertaking and subject that only in
a great volume could I hope to do it justice.
And in a story (such as this is intended to be), I
am afraid you would think I was trying to give you
pretty dry reading if I gave you too many facts and
figures.
Of course many of you have read of
the Canal in the newspapers—the controversy
over the choice of the route, the discussion as to
whether a sea level or a lock canal was best, and
many other points, especially whether the Gatun Dam
would be able to hold back the waters of the Chagres
River.
With all that I have nothing to do
in this book, but I hope you will pardon just a little
reference to the Canal, especially the lock features,
since Joe and Blake had a part in at least filming
those wonderful structures.
You know there are two kinds of canals,
those on the level, which are merely big over-grown
ditches, and those which have to go over hills and
through low valleys.
There are two ways of getting a canal
over a hill. One is to build it and let the water
in to the foot of the hill, and then to raise vessels
over, the crest of the hill, and down the other side
to where the canal again starts, by means of inclined
planes, or marine railways.
The other method is by “locks,”
as they are called. That is, there are built
a series of basins with powerful, water-tight gates
dividing them. Boys who live along canals well
know how locks work.
A boat comes along until it reaches
the place where the lock is. It is floated into
a basin, or section, of the waterway, and a gate is
closed behind it. Then, from that part of the
canal which is higher than that part where the boat
then is, water is admitted into the basin, until the
boat rises to the level of the higher part of the
canal. Then the higher gate is opened, and the
vessel floats out on the higher level. It goes
“up hill,” so to speak.
By reversing the process it can also
go “down hill.” Of course there must
be heavy gates to prevent the higher level waters from
rushing into those of the lower level.
Some parts of the Panama Canal are
eighty-five feet higher than other parts. In
other words, a vessel entering the Canal at Colon,
on the Atlantic side of the Isthmus, must rise eighty-five
feet to get to the level of Gatun Lake, which forms
a large part of the Canal. Then, when the Pacific
end is approached, the vessel must go down eighty-five
feet again, first in one step of thirty and a third
feet, and then in two steps, or locks, aggregating
fifty-four and two-thirds feet. So you see the
series of locks at either end of the great Canal exactly
balance one another, the distance at each end being
eighty-five feet.
It is just like going up stairs at
one end of a long board walk and down again at the
other end, only the steps are of water, and not wood.
The tug bearing Blake, Joe and Mr.
Alcando was now steaming over toward Toro Point break-water,
which I have before alluded to. This was built
to make a good harbor at Colon, where violent storms
often occur.
“I want to get some pictures
of the breakwater,” Blake had said, since he
and his chum were to present, in reels, a story of
a complete trip through the Canal, and the breakwater
was really the starting point. It extends out
into the Caribbean Sea eleven thousand feet.
“And you are taking pictures
now?” asked Mr. Alcando, as Blake and Joe set
up a camera in the bow of the boat.
“That’s what we’re
doing. Come here and we’ll give you lesson
number one,” invited Blake, clicking away at
the handle. “I will gladly come!”
exclaimed the Spaniard, and soon he was deep in the
mysteries of the business.
There was not much delay at the breakwater,
as the boys were anxious to get to the Canal proper,
and into the big locks. A little later their
tug was steaming along the great ditch, five hundred
feet wide, and over forty feet deep, which leads directly
to the locks. This ditch, or start of the Canal
proper, is about seven miles long, and at various
points of interest along the way a series of moving
pictures was taken.
“And so at last we are really
on the Panama Canal!” cried Joe as he helped
Blake put in a fresh reel of unexposed film, Mr. Alcando
looking on and learning “points.”
“That’s what you are,”
the captain informed them, “and, just ahead
of you are the locks. Now you’ll see something
worth ‘filming,’ as you call it.”
