PREFACE. 



In present ini;- tliis list of Progressive 

 Nature Studies for your consideration , I do 

 not for a moment presume that there are 

 no good books or outlines upon the market, 

 because there are many excellent ones. 



Neither do I write to improve upon them , 

 only as it touches our peculiar needs. 



The entire series will be composed of 

 gleanings from a large number of our 

 standard works, with some additions of my 

 own. 



Eespectfully submitted , 



G. W. Carver.
