mighty fine fellow, and we get along splendidly, and
I don't think I ever met a pair of more unselfish boys," said George, as
they walked up the hill.

"That is my opinion, too. Tom is a most wholesouled fellow, and we find
so much that is likeable in each other, that I tell you I do not feel
like being so niggardly as to keep the knowledge of the cave and the
treasure away from them; and I feel the more about it that way when I
think of the terrible suffering they have gone through."

"Just my idea, exactly. How much do you really think there is in the
cave? I mean, what do you think it is worth in money?"

"I am sure the Professor knows. It would be awfully interesting to know.
Isn't it funny the Professor never said anything about the worth of it?"

"Yes, he did. Don't you remember, just before we left on the big trip he
wanted to know whether we cared to take the risks among the savages,
when we had so much treasure in sight?"

"Yes, but that didn't indicate whether there was a thousand or a million
there."

When they reached the entrance to the cave, they sat down and talked
over the matter again. The lamps were left unlighted, and they made no
effort to enter it.

"I have half a notion to go back and talk to the Professor, and bring
the boys over." George looked at Harry inquiringly.

"Do you really mean it?" asked Harry.

"I do."

"Look over there; see who is coming," said George, with a laugh.

Red Angel was on the way with his gun. "You little rascal! How did you
find out we were over here?" He didn't answer, but he went up to George
and looked up into his face, as though he didn't quite understand that
kind of a greeting.

The boys picked up the lamps and went back to the house, and the
Professor was surprised at the early return, but he did not make any
mention of it to either of the boys, and nothing more was said about it
during that day or evening.

CHAPTER XIII

THE ACCIDENT TO JOHN AND THE RESTORATION OF MEMORY

The island yielded an abundance of nuts of various descriptions, the
most prolific being the Brazil nut, which grows in the form of a large
sphere, from three to four inches in diameter, the shell being very
hard, like the cocoanut, and when broken open is found to be filled with
the segmentally formed nuts which we all know.

This was gathered in large quantities, and was the principal source of
oil which was used for the lamps, as they had no other means of
illumina
