"O, yes; we have a way of getting news of people down there. Toby has nearly gone distracted on your account. He is positive that you are dead, for he believes you could never have got well out of his hands."

"And Miss—Mr. Villars——?"

"They have been so much disturbed about you, that I would have been glad to inform them of your safety, if I could. But not even they must know of this place."

"Where am I, then?"

"You are, as you perceive, in a cave. But I suppose you know so little how you came here that you would find some difficulty in tracing your way to us again?" This was spoken interrogatively, with an intelligent smile.

"I am so ignorant of the place," said Penn, "that it may be in the planet Mars, for aught I know."

"That is well! Now, sir," continued the negro, "since you have several times expressed your obligations to us for preserving your life, I wish to ask one favor in return. It is this. You are welcome to remain here as long as you find your stay beneficial; but when you conclude to go, we desire the privilege of conducting you away. That is not an unreasonable request?"

"Far from it. And I pledge you my word to make no movement without your sanction, and to keep your secret sacredly. But tell me—will you not?—how you came to inhabit this dreadful place?"

"Dreadful? There are worse places, my friend, than this. Is it gloomy? The house of bondage is gloomier. Is it damp? It is not with the cruel sweat and blood of the slave's brow and back. Is it cold? The hearts of our tyrants are colder."

"I understand you," said Penn, whose suspicion was thus confirmed that these men were fugitives. "And I am deeply interested in you. How long have you lived here?"
