THE UNDERGROUND RIVER
They gathered around the opening so
unexpectedly disclosed to them, and stared down into
the black depths. Beyond the first few steps of
the flight that led to they knew not where, nothing
could be seen. In his impatience Tom was about
to go down.
“Bless my match box!”
cried Mr. Damon. “What are you going to
do, Tom, my boy?”
“Go down there, of course!
What else? I want to get to the underground city.”
“Don’t!” quickly
advised the odd man. “You don’t know
what’s there. It may be a trap, where the
old Aztecs used to throw their victims. There
may be worse things than bats there. You’ll
need torches— lights—and you’d
better wait until the air clears. It may have
been centuries since that place was opened.”
“I believe that’s right,”
agreed Ned. “Whew; Smell it! It’s
as musty as time!”
An unpleasant odor came up the tunnel
entrance, and it was stifling to stand too close.
Tom lighted a match and threw it down. Almost
instantly the flame was snuffed out.
“We couldn’t live down
there a minute,” said the young inventor.
“We’ve got to wait for it to clear.
We’ll go back to the balloon and get some electric
flash lamps. I brought along a lot of ’em,
with extra strong batteries. I thought we’d
need some if we did find the city of gold, and it
looks as if we were almost there now.”
Tom’s plan was voted good so
they hurried out of the temple, their feet echoing
and re-echoing over the stone floor. The place,
ruined and desolate as it was, had no terrors for
them now. In fact they were glad of the very
loneliness, and Tom and Ned actually looked about
apprehensively as they emerged, fearing they might
see a sign of the Mexicans or the Fogers.
“Guess they can’t pick
up our trail,” said Tom, when, he saw of what
Ned was thinking.
“No, we’ve got the place
to ourselves. I wonder how long it will take
for the air to get fresh?”
“Not so very long, I guess.
There was a good draught. There must be some
opening in the underground city by which the air is
sucked in. They’d never have only one opening
to it. But we don’t need to look for the
other. Come on, we’ll get out the torches.”
These electrical contrivances are
familiar to all boys. A small electric lamp is
set in the end of a hollow tube of tin, and about
the lamp is a reflector. Dry electrical batteries
are put in the tin tube, and by means of a push button
the circuit is closed, illuminating the lamp, which
gives a brilliant glow. Tom had a special kind
of lamp, with tungsten filaments, which gave a very
powerful light, and with batteries designed to last
a long time. A clip on the spring controlling
the push button made it so that the lamp could be
made to give a steady glow. Thus they were well
prepared for exploring the tunnel.
It took some little time to get the
flash lamps ready, and when they were all charged
and they had eaten, they went back to the opening
to see if the air had cleared. Tom tested it by
dropping a match down, and, to his delight it burned
with a clear flame.
“It’s all right!”
he exclaimed. “The air is pure. Now
to see where we will bring up. Come on, everybody.”
“Jest one minute, Massa Tom,”
begged Eradicate, as the young inventor was about
to descend the steps, which even the brightness of
his lamp did not disclose the end. “Is yo’
gwine down dar, Massa Tom?”
“Certainly, Rad.”
“An’ is yo’—’scuse
me—but is yo’ expectin’ me fo’
t’ follow yo’?”
“Certainly, Rad.”
“Den, all I’s got t’
say is dat yo’ is ‘spectin’ too much.
I ain’t gwine t’ bury mahse’f alive
not yit.”
“But, Rad, this is where the
gold images are. If you don’t come down
with us you won’t get any gold.”
“Am dat so? No gold?”
The colored man scratched his head. “Well,
I shore does want gold,” he murmured. “I
reckon I’d better trot along. But one thing
mo’, Massa Tom.”
“What is it, Rad?”
“Was yo’ all aimin’
t’ stay down thar any length ob time? ’Case
if yo’ is yo’ all’d better take
along a snack ob suffin’ t’ eat. ’Case
when I gits among gold I don’t want t’
come out very soon, an’ we might stay dar all
day.”
“Good advice, Rad,” exclaimed
Ned with a laugh. “I think we may get hungry.
You go back and put us up a lunch. We’ll
wait for you.”
“Bless my napkin ring!
I think you’re right!” exclaimed Mr. Damon,
and Eradicate hurried back to the balloon to get some
of the condensed food.
He was soon back and then, with Tom
in the lead, and with everyone carrying an electric
torch, with a spare one in reserve, and with their
weapons in readiness the party descended the stone
steps.
Their footfalls echoed solemnly as
they went down—down into the unknown blackness.
They kept their bright lights playing here and there,
but even these did not dispell the gloom. On every
side was stone—stone walls—stone
steps. It was like going down into some vast
stretch of catacombs.
“Say, will we ever get to the
bottom?” asked Ned, when they had counted several
hundred steps. “Maybe this goes down to
the middle of the earth.”
“Well, ef it do I’m gwine
right along!” called Eradicate. “I’s
gwine t’ hab one ob dem gold images or bust!”
“And I’m with you!”
cried Tom. “We’ll have to get to the
bottom sooner or later.”
Hardly had he spoken than he came
to the last step, and saw stretching off before him
a long tunnel, straight and level, lined on both sides,
and bottom, with smooth stones that gleamed like marble.
“Now we are really in the tunnel,”
declared Ned. “I wonder what’s at
the end?”
“The city of gold, of course,”
answered Tom confidently.
Eagerly they hurried on. There
was a slightly musty smell to the air, but it was
fresher than might have been expected.
Suddenly Tom, who was in advance,
uttered a cry. It sounded like one of alarm,
and Ned yelled:
“What’s the matter?”
“Look here!” cried Tom.
They hurried up to him, to find him standing before
a sort of niche in the wall. And the niche was
lined with a yellow metal that gleamed like gold,
while in it was one of the golden images, the second
one they had seen, and the third they heard about.
“We’re on the trail! We’re
on the trail!” cried Tom.
“Heah! Let me hab dat!”
cried Eradicate. “I may not git anudder,”
and he reached up for the statue.
“Let it stay until we come back,” suggested
Mr. Damon.
“Somebody might take it,” said the colored
man.
“Who?” laughed Tom.
“There’s not a soul here but ourselves.
But take it, if you want it, Rad,” and Eradicate
did so, stuffing the image, which was only about four
inches high, into his pocket.
Then they went on, and they saw several
other images, though not of gold. Several niches
were lined with yellow metal, but whether it was gold
or not they could not tell. They did not want
to stop, as they were anxious to get to the underground
city.
“Hark! What’s that?”
asked Tom, when they had gone about a mile along the
tunnel. “Don’t you hear something?”
“Sounds like a roaring,”
agreed Ned. “Maybe it’s more of the
bats.”
“Doesn’t sound like bats,”
declared Tom. “It’s more like a waterfall.
Come on.”
They hurried forward, the strange
sound increasing at every step, until it filled the
tunnel with its menacing roar.
“That’s strange,”
said Tom in worried tones. “I hope we don’t
come to a waterfall.”
Suddenly the tunnel made a turn, and
as they went around the curve in the wall the sound
smote on their ears with increased violence.
Tom raced forward, focusing his electric lamp down
on the stone corridor. The next instant he cried
out:
“A river! It’s an
underground river and we can’t go any further!
We’re blocked!”
The others came to his side, and there,
in the glare of their lamps, they saw rushing along,
between two walls of stone, a dark stream which caused
the roaring sound that had come to them. The tunnel
was cut squarely in two by the stream, which was at
least thirty feet wide, and how deep they could only
guess. Swiftly it flowed on, its roar filling
the tunnel.
