nless accident should open up the mystery."

Jack, as our readers know who have read of his previous exploits,
possessed a wonderful faculty of discernment and a very clear and
penetrating astuteness. He was a born detective, and this natural gift
in the direction of solving mysteries had led him to become one. As
stated, he became very thoughtful--indeed, he said to the banker:

"Excuse me, sir, but let me think a few moments--yes, think while the
incidents of your remarkable narrative are fresh in my mind."

"Certainly," said the banker; "and let me tell you I have hopes that you
will succeed."

"You have?"

"Yes."

"What leads you to hope?"

"The gentleman who referred me to you said, 'If any man on earth can
solve the mystery, Jack Alvarez is the man.'"

"He was very kind to speak so highly of me."

Jack fell into silence, and his active mind was performing wonders of
detective investigation, and after a season he asked:

"How long was the man in your presence who confided this fortune to
you."

"He was with me over an hour."

"Do you recall his appearance?"

"As well as though it were yesterday that he stood in my presence--yes,
I possess a wonderful memory."

"How old are you, sir?"

"I am seventy."

"How old was the man who called on you?"

"He was a man between fifty and sixty, I should say."

"He had gray hair?"

"Yes, gray hair."

"The color of his eyes was black."

"No, sir."

"Oh, yes."

"No, sir, they were clear blue eyes; I remember that well. Why did you
say they were black?"

Jack laughed and answered:

"I was only aiding you to remember--working on the plan of a detective
I've read about, who always worked on the negative track, when trying to
develop positive facts from witnesses."

"By ginger! I never should have recalled the color of his eyes if you
had not positively stated that they were black."

"Then we have verified the theory?"

"Yes, indeed."

"He wore a high beaver hat, I am sure?"

"No, he did not; he wore a wide-brimmed slouch hat, what they used to
call a Kossuth hat."

"Oh, I see; but he wore low shoes?"

"No, he didn't; he wore boots. I remember that; he sat opposite me and
his pants were drawn up, exposing the leg of his boots."

"I see; and those boots were covered with black mud?"

"No, they were not," laughingly exclaimed Mr. Townsend. "They were
covered with the _red mud of New Jersey_."

"Nonsense, sir."

"I'll swear to that," cri
