XVIII ANNUAL REPORT OF THE DIRECTOR 
much to the knowledge of the traditionary history of Tusayan, 
and made an extensive study of the house lore and records of 
house-building ceremonials. He also reported a full nomen- 
clature of ‘Tusayan architectural terms as applied to the vari- 
ous details of terraced-house construction, with etymologies. 
He secured from the Navajo much useful information of the 
ceremonial connected with the construction of their conical 
lodges or “hogans,” supplementing the more purely architec- 
tural records of their construction previously collected by Mr. 
Mindeleff. As opportunity occurred he gathered typical col- 
lections of baskets and other textile fabrics illustrative of the 
successive stages of their manufacture, including specimens of 
raw materials and detailed descriptions of the dyes used. 
These collections are intended to include also the principal 
patterns in use at the present time, with the Indian explana-- 
tions of their significance. 
OFFICE WORK. 
Major J. W. Powe 1, the Director, devoted much time during 
the year to the preparation of the paper to accompany a 
map of the linguistic families of America north of Mexico, the 
scope of which has been alluded to in previous reports. This 
report and map appear in the Seventh Annual Report of the 
Bureau.

duties of the office, which have been placed in his charge by 
the Director, and with the completion of the linguistic map. 
Col. Maturry, after his return from the field work elsewhere 
mentioned, was engaged in the elaboration of the new infor- 
mation obtained and in further continued study of and corret 
spondence relating to sign language and pictography. In this 
work he was assisted by Mr. Horrmay, particularly in the 
sketches made by the latter during previous field seasons, and 
in preparing a large number of the illustrations for the paper 
on Picture-writing of the American Indians which appears in 
the present volume. 
Mr. J. Owen Dorsey did no field work during the year, but 
devoted much of the time to original investigations. Samuel
