you'll see whether there are or not," said Glen
Howard.

Then the speaker led the way to the entrance of what appeared to be a
very large ante-chamber, there being openings which resembled doorways
at the back. Both the side walls and the floor were of rock, and
showed evidences of the work of man. A square of light lay on the
floor, the sunlight falling through a cut in the rocky roof.

"We haven't ventured any farther than this," Glen said. "We were shaky
about coming in this far, for there is no knowing what one will find in
these holes. It is dark in the rooms beyond, and it is what one can't
see that he is afraid of."

"Besides," Jack Bosworth cut in, "we were hungry when we got here,
and--"

"Great Scott!" shouted Shaw. "Do you mean that you've brought something
to eat? Lead me to it. I never was so hungry in all me blameless
life."

Following the custom of Boy Scouts when preparing for a trip into an
unknown country, the three boys had provided themselves with a good
supply of provisions, and the hungry ones they had found were soon
enjoying a very satisfying meal.

"After we fill up," Frank said, busy with a whole pie, "we'll get our
flashlights and see what's in those other rooms. Say," he added,
turning to Nestor "what's the matter of bringing Fremont here---when we
get him?"

"I'll bet these rooms are ten thousand years old," said Peter.

After the repast was over Nestor drew Frank aside, while the others
were searching their outfits for the electric torches, and asked:

"You remember what I said about there being three men in the Cameron
suite the night of the tragedy?"

"Of course," was the reply. "Got something new on the subject? I guess
you have that matter on your mind day and night."

"I have," was the reply. "I'm always thinking about it. Well, I now
believe that there were four men there, but I can't think what the
fourth man wanted."

CHAPTER XVIII.

FREMONT AND THE RENEGADE.

While the boys were discussing the situation in the outer chamber of
what appeared to be a subterranean, prehistoric temple, or at least an
ancient habitation or place of shelter, George Fremont was moving down
the slope of the mountain at a slow pace, the outlaws showing signs of
exhaustion.

The big Englishman, known as "Big Bob" by the messenger who had
identified the boy for him, had ordered the boy's bonds removed, and so
he was scrambling along in comparative comfort, the way being quite
