to look upon. But it needed only a glance into the faces of either
giant to show that it was a struggle in deadly earnest.

Back and forth they reeled over the rocky floor of the tunnel, bones
and sinews cracking. One sought to throw the other, and first, as Koku
would gain a slight advantage, his friends would call encouragement,
while, when Lamos seemed about to triumph, the Indians favoring him
would let out a yell of triumph.

For a few minutes Tom and his friends watched, fascinated. Then they
saw Koku slip, while Lamos bent him farther toward the earth. The
Indian giant raised his big fist, and Tom saw in it a rock, which the
big man was about to bring down on Koku's head.

"Look out, Koku!" yelled Tom.

Tom's giant slid to one side only just in time, for the blow descended,
catching him on his muscular shoulder where it only raised a bruise.
And then Koku gathered himself for a mighty effort. His face flamed
with rage at the unfair trick.

"Bless my bath sponge!" cried Mr. Damon. "This is awful!"

"They must stop!" said Job Titus. "We can't have them fighting like
this. It is bad for the others. If it were in fun it would be all
right, but they are in deadly earnest. They must stop!"

"Koku, stop!" called Tom. "You must not fight any more!"

"No fight more!" gasped the giant, through his clenched teeth. "This
end fight!"

With a mighty effort he broke the hold of Lamos' arms. Then stooping
suddenly he seized his rival about the middle, and with a tremendous
heave, in which his muscles stood out in great bunches while his very
bones seemed to crack, Koku raised Lamos high in the air. Up over his
head he raised that mass of muscle, bone and flesh, squirming and
wriggling, trying in vain to save itself.

Up and up Koku raised Lamos as the murmur of those watching grew to a
shout of amazement and terror. Never had the like been seen in that
land for generations. Up and up one giant raised the other. Then
calling out something in his native tongue Koku hurled the other from
him, clear across the tunnel and up against the opposite rocky wall.
The murmuring died to frightened whispers as Lamos fell in a shapeless
heap on the floor.

"Ah!" breathed Koku, stretching himself, and extending his brawny arms.
"Fight all over, Master."

"Yes, so it seems, Koku," said Tom, solemnly, "but you have killed him.
Shame on you!" and he spoke bitterly.

Job Titus had hurried over to the fallen giant.

"He isn't
