PREFACE 



This study is dedicated to my wife and to the Dineh. The work was 

 begun in 1965, as a doctoral dissertation in sociology at The American 

 University. After its completion in 1961, it was expanded chiefly by 

 the incorporation of the results of the 1960 census and the consequent 

 revision of several sections of the text. 



My greatest debt is to Frank Lorimer, who was exceedingly patient 

 in trymg to extract me from many of the pitfalls which await the 

 unwary demographer. Many persons, both here m Washington and 

 at the Navajo Agency, were most generous in offering advice and 

 information. I am especially grateful to Robert W. Young, Francis 

 Felsman, and the late J. Nixon Hadley, whose insight and assistance 

 were invaluable. 



I wish, finally, to express my thanks to Miss Susan Colby, for her 

 painstaking and highly competent editorial efforts. Any errors which 

 remain are, alas, the sole responsibility of the author.
