Does "Both figure and counter are railed off" mean "both of them are far from the audience and separated from them"?
Context:
Both figure and counter are railed off, and only one man attends within side; and he is supposed to be the person with whom the stranger actually plays, by causing the arm and hand of the Automaton to move the Chess-men by some incomprehensible and invisible powers, according to the preceding move of the stranger who plays against the Automaton; and that every spectator should think so, he always places himself close to the right elbow of the Automaton, previous to its move; then puts his left hand into his coat pocket, and by an aukward kind of motion, induces most people to believe, that he has a Magnet concealed in his pocket, by which he can direct the movement of the Turk's arm at pleasure.
