"To operate this stabilizer of ours all the pilot will have to do is to guide the rudder with his feet.  The automatic pilot works the elevator and the ailerons.  It takes care of 'bumps' and 'holes' and sees that the machine banks at just the right angle on the turns.  This makes the operation of an airplane containing the stabilizer even more simple than running a motor-car, because you do not have to worry about going into different speed gears when climbing or descending.  You will notice on this drawing that strong piano-wires connect the instruments with all the necessary controlling planes of the machine."
