Albert Heyem Nachmen Baron translation
A rather extended study of the subject by H. A. Carr will be found in the Investigations of the Department of Psychology and Education of the University of Colorado, vol. I, Number 2, 1902. The late Professor Arthur Allin devoted much time to the investigation of play. See his brief article entitled "Play" in the University of Colorado Studies, vol. I, 1902, pp. 58-73. (Tr.)
