200 The Development Theory. 



the rhinoceros, the wild horse dwarfed and 

 giant the tapir, the camel and many stranger 

 forms long since passed away. 



At the time of this earlier chapter the 

 present Willamette valley was, through many 

 broad, open straits, in communication with 

 the sea. 



If now with. this extended view of its past 

 history, each epoch of which helped to form 

 the succeeding one, we say God created the 

 Columbia River valley, we of necessity are 

 held to imply through a long development of 

 forms and materials and forces like these now 

 at work around us, that among these were 

 the heat of internal fires, the frosts of unnum- 

 bered winters, changes of level and changes 

 in living forms on its banks; which of course 

 amounts to an acknowledgment that we re- 

 gard the development theory as defining 

 God's process of creating the Columbia river. 



What is here said of mountain mass or of 

 river channel applies with like force to the 

 creation of a whole continent.
