Field Work in Anthropology 107 



secured reveals a sub-horizon in the pre-Pueblo period. The 

 months of September and October were given to the examina- 

 tion of a new site on the Navajo Reservation which promises 

 to be of unusual importance. At the Aztec Ruin some new 

 finds were made. Adjoining the painted room reported upon 

 last year, another room was discovered, with ceiling standing in 

 good condition. The floor of this room was covered with earth 

 in which was a burial of unusual interest, accompanied by a 

 shield and many significant objects. Early in the year a large 

 circular depression in the court of the ruin was cleared out, re- 

 vealing a ceremonial structure of new type. In this case, we 

 find a large circular chamber, or kiva, surrounded by thirteen 

 rooms. There are also a number of unique features in the kiva 

 itself, one being a kind of stage, or elevated floor, upon which 

 parts of the ceremonies may have been conducted. 



In July, Mr. Charles L. Bernheimer equipped, financed, and 

 led an expedition into the little known Navajo Mountain coun- 

 try of Arizona and Utah. Mr. Earl H. Morris

Expedition country traversed proved to be exceedingly rugged 

 and difficult, but the party succeeded in working 

 its way through a number of deep narrow canyons in which 

 were found some small scattered ruins. Though the nature of 

 the trip precluded all attempts at excavation, it was possible to 

 collect samples of pottery sufficient to approximately date all 

 these sites. 



Advantage was taken of an offer of cooperation from the 

 Historical Society of North Dakota to study the ceremonies of

 the south, but since first visited, living with the 

 Mandan and Hidatsa along the Missouri River. Accordingly, 

 Curator Goddard joined Mr. Melvin R. Gilmore of the North 

 Dakota Historical Society in August to observe and record the 

 annual ceremonies. As no important data upon the ceremonies 

 of these Indians have been added since the report of their first 

 observer in 1833, the results of Dr. Goddard's visit will con- 

 stitute an important contribution to the subject.
