A desire to render anthropometric methods uniform and useful resulted in a “Manual for Physical Measurements in connection with Association Gymnasium Records,” which was ready in 1892. An anthropometric chart was also compiled and published. He read a paper on “The Value of Percentile Grades” before the American Statistical Association February 10, 1893, and for Volumes II and III of _Physical Education_ (November, 1893, to January 1895), prepared a series of articles on “Physical Measurements and How They Are Studied.” In connection with the summer conferences various “hygienic drills” and lists of exercises on apparatus suitable for Association use were elaborated. James Naismith, an instructor at the Training School, invented basket ball in the autumn of 1891 to meet the need of a good indoor game, and it was described in the _Triangle_, the school paper, for January 15, 1892. To promote all-around development a _Pentathlon_, comprising the hundred-yard dash, throwing the twelve-pound hammer, the running high jump, the pole vault, and the mile run, was recommended, with a scheme for uniform scoring. Some years of agitation and discussion led in 1895 to the formation of the Athletic League of Young Men’s Christian Associations of North America, designed primarily “to band together those who feel that athletics are often large elements in the formation of character, and to arrange for them lines of coöperation;” and “to foster a better spirit of manliness in connection with these activities that will banish from them the discourtesy and dishonesty by which they have been too often disgraced.” The first official handbook of the League was issued in 1897.
