Mr. Fletcher Pratt, a New York author, who ha. just published a history of the American Navy, has invented a new war game, called Pratt s War Game. It is apparently no amusement for the average person, for it is based on an intricate mathematical formula, which, by adding speed, fire power, armament and tonnage, resolves the efficiency of any warship in the world to a single number. Teams are given 45 seconds to manoeuvre and 15 seconds to shoot, guessing ranges in inches, with a referee to measure hits or misses with a tape. Mr. Pratt spent two years making models for the game, and his formula has sometimes been found more efficient than that used by the American Naval College at Newport.
