“O’ course, sir.”

Mark sat thinking for a few moments.

“We might try it with a little.”

“It must be a big dose or none at all, sir.”

“Yes, and we must risk it,” said Mark. “Now, then, it must be done quietly, for depend upon it that scoundrel is watching us.”

“Then I tell you what,” said Tom, “as now it’s dark he can see us, and we can’t see him, I say, sir, let’s all have a nap, and directly after the sun’s up get ready.”

“That’s good advice, Tom. We can sleep in peace with the way of escape open to us—that is, if we can.”

“T’others can, sir,” said Tom; “they’re all sound enough.”

Mark glanced at their companions, who had been unheeded during their earnest conversation, and could see that his lieutenant’s words were correct.

“Let’s lie down, then;” and, setting the example, his mind was so utterly weary, and yet so much at peace, that he was soundly asleep in less than five minutes, Tom Fillot in two.
