"

"I thought so, too."

"I don't care about going any farther without we have some one with us
and can have a decent light."

The boys hurried to the camp, and waited for John. When he came they
hurriedly related the experience.

"That will do to investigate."

"We saw a cross in there, moving up and down."

"Have we any of the candles with us?" he asked.

"Possibly; I can soon tell."

Tom came back with the news that he had found a box of them.

"As the village is quieting down, we shall have plenty of time to make
the examination to-night. We must wait until Muro returns, so as to get
the latest news, and can then start out."

Muro returned shortly after, and together with the boys, went up the
hill, and entered the mouth of the cavern. Three candles were lighted.
The great cross was before them, but it was such a different thing, now
that they were face to face with it. The end of the chamber, which the
light penetrated, had four openings to the chambers beyond, two above
and two below. These openings were separated from each other, and the
white walls between the openings appeared to form the white cross.

It was wonderfully realistic, this fanciful and fantastical carving of
nature through the rocky structure.

"But I saw it move; that is sure," said Tom.

"Did you see that move, or was it the light of the match that moved?"
asked John. "Imagination plays many a trick, during the excitement of
the moment."

John took the light, and by moving it up and down showed how the beams,
shining past the glistening walls, would cause the illusion of the cross
moving.

The cavern was found to be much broken up as they advanced, and reaching
the second set of chambers, it was evident that some one had lately
occupied it. Penetrating farther into the interior, they were surprised
to see articles of savage clothing, and long reeds, that had been burned
at the ends, together with utensils for cooking.

"We have entered one of the homes of the medicine men of the Tuolos. I
have no doubt they are now at the village attending the festivals, and
we had better leave as quickly as possible."

Before the entrance was reached they heard a great commotion outside,
and their own people rushing to and fro, and as they were emerging three
fantastically garbed natives met them. John ordered them to halt in the
native tongue, and they stood there irresolute. The boys also leveled
their guns at them, and they submitted as
