CHAPTER XIII

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 water-line, 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.
