XII BUREAU OF AMERICAN ETHNOLOGY [Bull. 184] 
Angus M. Babcock has redrawn, with great skill and competence, 
sketches of kachina masks, ceremonial costumes and paraphernalia, 
and diagrams of ceremonies made by my informants. I am now at 
liberty to thank him also for similar drawings made for ‘““The Pueblo 
of Santa Ana, New Mexico.” 
No words can adequately express my sense of obligation to my Sia 
informants. Some of them had a deep sense of mission in our joint 
labors, that of preserving for the world a record of their aboriginal 
culture. Some of them assisted me at considerable inconvenience 
and even sacrifice to themselves. And all incurred a risk, not to be 
minimized, in imparting esoteric and forbidden information. 
My wife, Mary, was of inestimable help to me through many years 
of fieldwork. Her gracious personality, her warm and sincere friend- 
liness, made our relationships with the Sias much easier and more 
rewarding. She performed much of the tedious labor of transcribing 
my field notes and typed a portion of the final manuscript. She did 
not live to see it finished. 
To the Center for Advanced Study in the Behavioral Sciences I am 
indebted for hospitality and assistance in the final preparation of 
this study for publication.
