XIV PBEFACE 



Three phases of association with nature may be generalized from 

 what is conjectm'ed and observed of the course of development of 

 man. These are; 



1. Dependence on nature, 



2. Beginning interdependence of man and nature, growing 

 toward 



3. Independence now observed in certain lines and pointing 

 out the goal of ultimate achievement. 



To express broadly the history of man and fire we have: 1, Man 

 fireless, hypothetical stage; 2, man adopts fire; 3, man develops fire 

 and himself; 4, man invents the firestick; and 5, man inherits the 

 earth.
