Double Faults.
The system of “double faults” deserves explanation. The educational value of the game is high, fostering as it does quickness of observation and that desirable attribute, an eagle-glance. When a player has had some little practice he will often score winning points from behind the specimen. Thus a side-whiskered gentleman may be claimed from the rear but, on drawing level with the quarry, it is observed that the chin is bare ... double fault.
