my young mastah," replied Old Ben. "Why shouldn't I try to sabe
him?"

"You are the fellow who saved Jack years ago, when the shipwreck
occurred, I believe."

"I am, sah."

"Then I am glad I have you in my power," answered Dr. Mackey. "You may
prove useful to me."

CHAPTER XXIX.

THE ESCAPE FROM THE CAVE.

Dr. Mackey turned away to consult with the guerrillas, and Jack and his
companions were left to themselves for the best part of half an hour.

The surgeon was evidently much disturbed over something, and Jack caught
the words, "must leave the country," and "I will send the money," spoken
to the guerrilla captain.

"Can it be possible that he intends to leave the States?" mused our
hero. "Well, we can easily get along without him. But I would like to
know more of that fortune."

At length Dr. Mackey came to him and sat down by his side.

"So you thought to escape me, did you?" he began.

"Do you blame me?" questioned our hero, as coolly as he could.

"Not exactly. But I want to warn you that it won't pay to try to escape
again. I have given the soldiers orders to shoot you down, if you
attempt it."

"In that case they must be outlaws, not soldiers, Dr. Mackey."

"They know how to obey orders."

"Again I demand to know what you are going to do with me."

"If you wish to know so much, I will tell you. I am going to take you
out of the country."

"To where?"

"That you will learn after we are on shipboard."

"Then you intend to take me away from America?"

"Yes."

"Are you going to take me to Europe?"

"As I said before, you'll learn your destination when you are on
shipboard."

"Supposing I won't go with you?"

"If you won't go peaceably, I'll have to use force, that's all."

"You mean you'll drug me, or something like that?"

"Never mind the details. You'll go with me, and that ends it. Moreover,
you'll do just as I want you to."

"When do you intend to take me away?"

"That will depend upon circumstances. Probably to-morrow night, or the
next day."

"What of my companions?"

"Old Ben shall go with us."

"And Columbus?"

"Is that the nigger's name?"

"Yes. Columbus Washington."

"The guerrillas will take care of him."

"Do you mean to say they will shoot him?"

"What if they do? Niggers don't count in this world."

"I think you are a monster, Dr. Mackey!" exclaimed our hero, in horror.
"To kill a negro is as much murder as to kill anyone else."

"I won't dis
