THE RISING FLOOD
Stumbling, slipping, sliding, half-falling, bruising themselves on the
sharp rocks, but ever leaping forward toward the sides of the tunnel,
and away from the depressed centre down which they could see the rush
of waters coming, the boy ranchers at last managed to reach the granite
wall. Nort had succeeded in grabbing up one of the lanterns, but there
was no time for Dick or Bud to take one, and the food had to be
abandoned.
"Climb up! Climb up, if there's a ledge!" shouted Bud. "We'll be
drowned if we can't get above the water!"
He had, somehow or other, brought up in the rear. Though he did not
admit it, this was because he had shoved his cousins ahead of him,
hoping thus to enable them to gain a safe place.
And as Nort and Dick glanced back they saw, in the gleam of the one
lantern left alight, a white mass of water bearing down on them, and,
seemingly, filling the tunnel from wall to wall, as it rushed foaming
and murmuring onward.
It was as though a dam had suddenly burst, or some obstruction had been
removed, allowing the pent-up waters to rush along the accustomed
channel. And if you have ever noticed a dammed-up stream, say in some
gutter, thus quickly released, you can imagine what happened on a
larger scale in the tunnel where the boys were.
The water, normally, flowed only in the four-foot channel. But now it
spread out on either side, and, of course, was much deeper in the
centre. But as the tunnel sloped from either wall, in a sort of V
shape to the centre channel, naturally the parts nearest the side walls
were less covered by water than the others.
It was because of this that Bud, Nort and Dick were enabled to maintain
a footing, though they were knee-deep in water in an instant, and the
one remaining lantern had to be held up to prevent it from being
engulfed and extinguished in the sudden flood.
"Climb up! Climb up!" shouted Bud. "Isn't there some place--some
rocky ledge--where you can find a footing? The water's getting deeper!"
And this was true. Either the flood was growing at its source (a place
as yet unknown to the boys) or it was running too rapidly, and in too
great a volume, to accommodate itself to the tunnel channel, and was
thus piling up in the vicinity of the boys.
"What happened? What caused it?" cried Nort.
"Never mind that--now!" shouted Bud. "Find the highest place you can,
and stick!"
"Suppose the whole tunnel fills?" asked Dick, trying to pierce the
semi-gloom, and look for a refuge on the rocky wall.
"If it does we'll have to swim for it," grimly said Bud. "But isn't
there some place where you can climb up?"
"This looks like a ledge," Dick answered, as he caught sight of a
darker shadow on the rocky wall of the tunnel, above his head, when his
brother swung the lantern.
"Just what we need!" exclaimed Bud, as he waded through the
ever-deepening water to the side of his cousins. "Up with you! Here,
Nort, I'll hold the lantern until you make it!"
Thus, again, Bud was seeing that his cousins reached a place of
comparative safety before he looked to himself. For they found the
ledge, once they had scrambled up to it, well above the water, and wide
enough to give shelter and a safe perch for all three.
"Whew! That was touch and go!" murmured Bud, as he leaned back, half
exhausted, against the rocky wall at the rear of the ledge.
"I should say so!" gasped Dick. "It all happened so suddenly that I
don't know yet what it was all about."
"The stream suddenly started flowing again," spoke Bud. "That's all
there was to it. Must have been dammed up some place, and suddenly
released. It's still rising, too," he added, as he leaned forward and
held the lantern down over the ledge where he and his cousins had taken
refuge.
"Rising?" sharply inquired Nort, and there was a tone of anxiety in his
voice.
"Yes," remarked Bud, as he swung the lantern to and fro. "We didn't
get up here any too soon, fellows! Look, the water would be up to our
waists down there now, in the most shallow place, and it's got speed
like one of Christy Mathewson's curves!"
His cousins could see that he had not exaggerated the matter. The
waters were rising. Inch by inch, and foot by foot, the flood was
approaching the crest. Where the boy ranchers had sat in the almost
dry bed of the stream, to eat their lunch, there was now a mad race of
swirling waters. Where they had stood, before climbing up to the ledge
of safety, there was now three feet depth of water. And, as Bud had
said, it was flowing along so swiftly, like the stream which turns a
mill-wheel, that the boys could hardly have been able to keep their
feet had they been down in the current, or even on the weakest edge of
it.
But, as they were, they were safe for the time being. How long that
would be the case none could tell. They could see, in the gleam of the
one lantern saved in the mad rush, that the stream was coursing along
as it had never coursed before.
"There must be a powerful lot of water coming out of the reservoir
pipe," Nort remarked.
"Biggest ever, with all this water behind forcing it out," agreed Bud.
"I hope the pipe holds."
"It isn't as if the pipe were the only outlet," said Dick. "You know
the water can flow out of the tunnel above, and on either side of the
conduit."
"Yes," agreed Bud, "and dad had it put in that way on purpose, so if
ever a big flood did come, the tunnel could relieve itself without
ripping away the pipe and reservoir. There's a sort of spillway at one
side of the reservoir, you know."
The boys from the east had noticed this. Up to now no water had run
off through this auxiliary channel, but it was there for emergencies
such as now had occurred. And the water could find a vent and outlet
down the middle of Flume Valley, as, indeed, the surplus from the
reservoir itself did, when there was any.
"Well, it sure is queer, and we had a mighty narrow escape," remarked
Nort, as Bud leaned back again with the lantern. "But the fellows back
at the camp will be scared."
"I reckon they will," admitted Bud. "They'll see the water spouting
out, in a greater volume than ever before, and they'll imagine all
sorts of things have happened to us."
"Well, nothing has happened yet--except we've lost two perfectly good
lanterns, and what grub we didn't eat," asserted Nort.
"But something else may happen," said Bud in a low voice, as, once
more, he leaned forward, and again held the lantern over the edge of
the rocky ledge.
"What?" Dick wanted to know.
"Look," was what Bud replied. And his cousins, glancing down, saw that
the waters were rising, rising, rising!
When would they stop?
