In a word, I should have set this man down as one of the safest of men to be employed in that capacity, but for the circumstance that while he was speaking to me he twice broke off with a fallen color, turned his face toward the little bell when it did not ring, opened the door of the hut (which was kept shut to exclude the unhealthy damp), and looked out toward the red light near the mouth of the tunnel. On both of those occasions, he came back to the fire with the inexplicable air upon him which I had remarked, without being able to define, when we were so far asunder.

Said I, when I rose to leave him, "You almost make me think that I have met with a contented man."

(I am afraid I must acknowledge that I said it to lead him on.)

"I believe I used to be so," he rejoined, in the low voice in which he had first spoken; "but I am troubled, sir, I am troubled."

He would have recalled the words if he could. He had said them, however, and I took them up quickly.

"With what? What is your trouble?"

"It is very difficult to impart, sir. It is very, very difficult to speak of. If ever you make me another visit, I will try to tell you."

"But I expressly intend to make you another visit. Say, when shall it be?"

"I go off early in the morning, and I shall be on again at ten to-morrow night, sir."

"I will come at eleven."
