LET the -moulders of public opinion in the chief 

 subjects usually called humanistic — history, soci- 

 ology, economics, politics, ethics, religion — once 

 they come to see how fundamentally soundness of view 

 and healthfulness of life in all these domains are de- 

 pendent upon correct elementary information about 

 nature, and innumerable students of educational prob- 

 lems, teachers, and public-spirited and philanthropic 

 persons concentrate their thought and ingenuity upon 

 surmounting the practical difficulties in the way of 

 securing the contact with nature which 'is indispens- 

 able to such information and attitude. 



— Dr. William E. Ritter.
