PREFACE XI 



the trading post is not yet an obsolete institution. It remains a fixed 

 point in the constantly shifting spectrum of Navaho-White relations, 

 as it has been for over half a century, giving a measure of direction 

 and stability to the process of Navaho cultural adaptation. As such 

 its importance is likely to persist at least for another generation be- 

 fore it finally and fully gives place to more up-to-date enterprises.
