had brought them through.

The tall, thin fellow's hair had turned utterly white. But so had his
soul.

"You're a good man, Maget," said Professor Gurlone. "You have saved
us, and you have been brave as a lion."

Maget shook his head. "Professor," he said. "I came into the jungle to
rob you. Durkin and I bribed Juan to steal that radium, and I feel
responsible for his death. We thought you had diamonds or gold in the
Matto Grosso, and we were after it. That's why I am here."

"You have repaid your debt to us, more than fully," said Kenneth,
holding out his hand.

"Yes," said Espinosa.

"Will you keep me with you, then?" asked Maget anxiously. "Are--will
you go back there?"

Professor Gurlone stared at him, and then said, in a surprised tone,
"Why, of course!"

"But the monsters?" asked Maget.

"Many of them will die in the outer air," said Gurlone. "The survivors
of the battles will start eating the dead. They will finally clear
away the debris of dead creatures about the radium shack. As each is
exposed to the rays of the concentrated metal, it will die. The others
will eat it, and be killed in turn. Thus, they will be destroyed. If
there are any survivors after this evident turn of events, then we
will cope with them when we return, reinforced. Dynamite, enough of
it, will finish them off. And, Maget, in your next pursuit after
knowledge of strange things, you may get a few earthly riches. The
radium is still there, and you will share in it."

"Thank you," said Maget humbly. "I'm with you to the end."

"You must keep quiet about this," cautioned Kenneth Gurlone. "We do
not want the world to know too much of our vast store of radium. It
would attract adventurers and we would be annoyed by ignorant men. But
we're thankful you lay drunk in that saloon when my father spoke of
the millions, Maget."

In Manzos, Maget found himself a changed man. To his surprise, in
spite of his white hair, brought on by the horror of what he had seen,
he found that he had gained two inches in height, and that he was
larger of girth. This, Professor Gurlone told him, was the effect of
the radium rays.

Never again did Maget lie drunk on the floor of a saloon. The events
through which he had gone had seared the tramp's soul, and he kept
close to his new master, Professor Gurlone.
