He took no notice of the speakers, and soon pretended to be asleep.
"Do you know who is in that berth, Warton ?" asked one of the four men, speaking in a low tone, but loud enough to enable Christy to hear him.
"I don't know; do you, Rockton ?" replied the one addressed; and it was evident to the listener that the men were at least persons of average education with but little of the common sailor in it.
"I do; one of the officers told me all about it not half an hour ago," answered Rockton.

"The fellow who is asleep there is the other Passford." "Is that so?
Then we mustn't talk here," added Warton, apparently somewhat alarmed.

"Who told you so ?" "I said one of the officers; and you know as well as I do which one." The speakers said no more, but leaving the locality near the berth, they moved forward in a body.

Christy was sorry he was not to hear any more of the conversation; but he felt that he had made some progress in his work.

He had obtained the names of two of the men, and ascertained that one of the officers in the ward room was a Confederate.
