ng fit. "It was an act of Christian charity, and I am glad that we
were able to share it with you."

"That's right, and nicely spoken of you, doctor," said the American;
"but I wish we had been able to help the poor fellow sooner. Here, I'm
burning to know how he got into such a state. I s'pose he told you?"

"He told me a great deal," replied the doctor, "but the time was short,
his words hurried, and what he said has set me considering as to how
much is simple fact and how much the imagination of a diseased brain."

"Hah!" exclaimed the American. "Then the best way will be for you to
tell us too, and then maybe we shall be able to help you sort it out,
and untangle the real thread from the touzly yarn."

"Exactly," said the doctor. "Well, it seems that he was one of a dozen
adventurous prospectors whose brains had been excited by one of the old
legends respecting the discovery of gold by the old mission fathers in
one of the deserts between here and Arizona. They banked their funds
together, purchased necessaries and provisions, and started with a mule

"When all was ready they started, well armed, as I understood him,
making for the south and west. They had certain plans which they had
obtained from explorers, and went out in full hope of discovering not
only a new land of gold, but a city said to exist in the middle of one
of the deserts, a ruin now, but containing fabulous wealth amassed by
the emperor, cacique, or whatever he was called, and fostered by the old
mission fathers, who had made the city their home."

"Hah!" cried Griggs. "This makes one's mouth water. Go on, doctor."

The latter looked at him seriously, and then continued--

"All this sounded very clear and reasonable, but after a time there was
so much of the marvellous in the poor fellow's descriptions that I could
not help feeling that we were getting into the dreamland of an
enthusiast."

"Let us hear, Lee," said Wilton.

"To be sure," cried Griggs.

"I say that," said the doctor, "because, as I seemed to gather, th
