We are informed that Major De Bernardi's average speed for the flight was 318 3/4 mph, and at one time the speedometer was registering 349 mph. From telegraphic advice we have just received from our Italian representative, the CHAMPION SPARKING PLUGS functioned entirely satisfactorily, and were stated by Major De Bernardi to have assisted him appreciably in putting up a new World's Air Speed Record.
