AMERICAN NATURE-STUDY SOCIETY 



The attention of members is respectfully called to the following which in 

 circular form is being distributed. Your cooperation in the camjiaign for 

 new members is needed. 



This Society was organized in January. 1908. Its purposes, 

 as stated in the constitution, are: (1) to promote critical and 

 constructive investigation of all phases of scientific nature-study 

 (as distinguished from technical science) in schools, especially 

 all scientific studies of nature in elementary schools; and (2) to 

 work for the establishment in schools of such nature-study as has 

 been demonstrated valuable and practicable for elementary 

 education. 



It should be noted that the term nature-study as quoted above 

 from the official transactions of the society stands for all that is 

 best in scientific studies of natural objects and processes, in 

 elementary schools especially ; and accordingly the interests and 

 activities of the Society include biological nature-study of plants 

 and animals, physical nature-study of lifeless things (often 

 called "elementary science'*), study of the human body ("physi- 

 ology and hygiene"), school-gardening and elementary agri- 

 culture, and the observational phase of geography. These are 

 not to be regarded as so many diverse and antagonistic subjects, 

 for as now best taught there runs through all a strong bond of 

 union, which is simply the nature-study idea.
