“But,” asked the sailor, “where are your companions? I thought there were four of you.”

“Listen to me, sir. I’m not the man you take me for; you are in Captain Rogers’s post, are you not? under orders from General Cromwell. Mine, also, are from him!”

“Indeed, sir, I recognize you; you are Captain Mordaunt.”
