Do n't fire . Please point me in the direction of the Boyne , '' said Robert . The sentinel lowered his musket as if saying to himself , `` This must be one of the officers of the frigate who has been on shore having a good time . '' `` The Boyne is right out in that direction , '' said the sentinel , pointing with his musket , `` but my orders are not to let any one pass along the wharf after ten o'clock without they give the countersign . '' `` All right ; always obey orders . I 'll come to the wharf . '' Robert could hear the dip of oars in the fog , and knew it must be the patrol boat pursuing him .
