WHERE DID IT GO?
Pressing back toward the rocky ledge, against which they leaned, gazing
with fearsome eyes at the rising waters, on which the lantern-light
shone fitfully, and almost holding their breaths at times, so great was
the strain, the boy ranchers waited--for what they scarcely knew. And
yet they did, in a measure.
For they waited to see if the waters would stop rising, a happening, as
they well knew, which, alone, could save their lives.
As one of them had remarked, they might have to swim for it. But,
looking at the foaming current, dashing along over jagged rocks on
which the boys had more than once stumbled, they knew what a risk that
effort to escape would bring.
And should the water fill the whole tunnel they would have no earthly
chance!
For only a fish can exist in a hose or pipe completely filled with
water, and that is what the tunnel would become if the water rose to
the roof--merely a great, underground rocky pipe for the conveying of
the liquid from Pocut River.
So you can easily imagine with what anxiety Bud, Nort and Dick watched
the rising water. Every now and again one of them would lean over the
ledge, swinging the lantern to and fro, so its gleams would be
reflected in the hurrying, foaming stream, and indicate how fast it was
rising.
At first the rate of rise had been rapid. But as the boys, again and
again, made observations in the semi-gloom Bud, at length, uttered a
joyful cry.
"Look!" he shouted, pointing with trembling finger at the foamy flood
close, now, to the top of the ledge. "Look!"
"What--a big fish?" asked Dick.
"Fish nothing!" retorted his cousin. "But the water is going down!
Look, it isn't as high as it was. I can see a wet mark where it came
up to, and it's two inches below that now! The flood is going down!"
"Are you sure?" asked Nort, eagerly.
"Look for yourselves!" invited Bud, handing over the lantern.
Nort's observation was confirmatory of his cousin's.
"She _is_ going down!" remarked Nort. "And just in time, too!"
How truly he spoke was evidenced by that fact that another inch of rise
would have sent the flood over the ledge on which the boys rested!
So narrow had been their escape!
"If she only doesn't begin to rise again, after she starts going
down--as you say she is--we'll be all right," said Dick. "But if she
comes up----"
He did not finish what he started to say, but his companions knew what
he meant, and they looked each other in the face with grave
apprehensions.
"The question is now," went on Bud, as he again took an observation and
noted that the flood was still on the descent, "how long we shall have
to stay here."
"If it's too long we'll be wanting some of that grub which was washed
away," asserted Diet. "In fact I dropped a sandwich half eaten."
"Same here," remarked his brother. "But let's hope that it will go
down as suddenly as it came up."
That was all they could do--hope; but it bore fruits, for in about an
hour, as they ascertained by glances at their watches, the flood was
almost down to the normal channel of the underground stream.
"And if it will only stay there we can venture to keep on to the other
end of the tunnel," spoke Bud.
"Will you do that?" Dick wanted to know.
"Why not?" asked Bud. "We want to see what happened, and where this
water goes to when it disappears so suddenly; don't we?"
"Yes," agreed Dick. "But I thought, after our escape, that we had
better head back for camp."
"It's about six of one and half a dozen of the other," asserted Bud.
"We're almost half way through the tunnel, now, and we might as well
keep on. I'd like to solve this mystery, and we can't if we call it
off now."
"That's right," assented Nort. "We don't run any more danger going on
to the river end of the tunnel than we would in going back to the camp
end. That is unless we discover a big cavern, or hole through to
China, in the other end of the tunnel. Even then we might be able to
skirt around it."
"Let's go on!" suggested Bud, as he prepared to climb down off the
ledge. "This thing has my goat!"
"Speaking of goats is most appropriate on a cattle ranch," laughed
Nort, and the spirits of all the lads were lighter now. "But let's
keep on to the end for which we started!"
This was agreed to and, after waiting a little while to make sure that
the waters were not again going to rise, away started the boy ranchers.
They were traveling lighter now, for they only had one lantern, and no
food to carry.
The remainder of the tunnel was as the first part had been--a great,
uneven tube through the mountain, twisting and turning here and there,
sometimes the roof being so high that it did not show in the swinging
lantern-light, and again being low enough, almost, for the boys to
touch.
On all sides was evidence that the flood had been here, as it had been
at the place where the boys took refuge. Now and then they came to
deep pools, which they had to skirt, and, in one case, leap over.
Suddenly, as they were walking along, the lantern which Bud was
carrying went out, leaving them in pitch blackness!
"Hello! What's the idea?" asked Nort.
"Did you do it on purpose?" asked Dick.
"Why, no, of course not!" asserted Bud. "The oil must be gone, though
I filled it before we started, and it ought to have burned longer than
this."
"Whew! This is tough!" bemoaned Nort. "Left in the dark!"
"Not altogether!" exclaimed Bud. "I brought some candles!"
"Great!" voiced Nort. "Light up!"
Which Bud did, placing a short length of candle inside the lantern, by
fastening it, with some grease that hardened, on top of the oil
reservoir of the wick.
"But I can't understand what happened to the lantern," went on Bud,
making an examination by means of a second candle, from the store he
had, luckily, placed in his pocket. "Oh, yes, I can!" he went on.
"What?" asked Dick.
"One of the soldered seams of the lantern oil tank started, and the oil
has leaked out. Guess one of us must have banged it against a stone
when we made the rush. But we'll be all right. A candle in the
lantern is nearly as good as the regular wick."
It was not quite so good, but the boys made the best of it as they
tramped on through the tunnel, hoping to reach the river end without
another flood, or any mishap.
"The water seems to be behaving very nicely," observed Nort, as they
all saw that the stream was well within its rocky channel.
"But what gets me," said Bud, "is where it goes to--when it goes. I
mean where does it disappear to? We haven't come to a single branch
tunnel, or any other passage that could drain off the river water."
"That's right," agreed his cousins.
"But maybe we'll find it further on," suggested Nort.
"We'll soon know, for we must be close to the other end now," observed
Bud. "Our candles are holding out well."
They had come several miles, as they knew by the time consumed. The
way through the tunnel had been uphill all the way, as it must needs be
to allow the water to run down to the reservoir in Flume Valley. But,
so far, they had seen nothing to indicate any side channel for the
stream--any place that might drain off the water, and return it in such
a sudden volume as to cause a flood.
"I can't understand it," Bud remarked as he swung the lantern to and
fro. "It sure is a puzzle. Where does the water disappear?"
His cousins could offer no solution. All the way along they had
carefully scanned the underground stream, but there appeared no break
in its uneven, rocky bank in the middle of the tunnel.
"Well, let's keep on," suggested Nort. "We aren't at the end yet, and
it may be close to the intake--I mean the mysterious influence--that
shuts off our water supply and turns it on again, may be there.
Forward, march!" he cried gaily.
Together they started off, having come to a momentary halt to inspect a
place wider and deeper than usual, when Bud suddenly came to a stop and
exclaimed:
"Some one is coming!"
