XXVI INTRODUCTION. 
Stearns, of Short Hills, N.J., made a few additions to his already 
valuable donations of relies from the ancient graves of Chiriqui, 
Colombia, and Mr. J. N. Macomb presented a number of frag- 
ments of earthenware from Graham County, North Carolina. 
Some important accessions have been made by purchase. A 
large collection of pottery, textile fabrics, and other articles 
from the graves of Peru was obtained from Mr. William E. 
Curtis; a series of ancient and modern vessels of clay and 
numerous articles of other classes from Chihuahua, Mexico, 
were acquired through the agency of Dr. E. Palmer; a small 
set of handsome vases of the ancient white ware of New Mexico 
was acquired by purchase from Mr. C. M. Landon, of Lawrence, 
Kansas, and several handsome vases from various parts of 
Mexico were obtained from Dr. Eugene Boban. 
Mr. Vicror MrnpeLerr was engaged during the fiscal year 
in the preparation of a report on the architecture of the Tusa- 
yan and Cibola groups of pueblos, which appears in the present 
volume. This report contains a description of the topography 
and climate of the region, in illustration of the influence of 
environment upon the development of the pueblo type of 
architecture. It also contains a traditionary account of the 
Tusayan pueblos and of their separate clans or phratries. A 
description in detail of the Tusayan group treats of the relative 
position of the villages and such ruins as are connected tradi- 
tionally or historically with them. A comparative study is 
iilso made between the Tusayan and Cibola groups and be- 
tween them and certain well preserved ruins in regard to con- 
structive details, by which means the comparatively advanced 
type of the modern pueblo architecture is clearly established, 
Maps of the groups discussed and of the topography of the 
country and ground plans of houses and apartments were pre- 
pared to illustrate the report and give effect to the descriptions 
and discussion. 
Mr. Cosmos Minpreverr devoted the early part of the fiscal 
year to the preparation of a report upon the exhibits of the 
Bureau of Ethnology and the Geological Survey at the Cin- 
cinnati Industrial Exposition, 1884; the Southern Exposition 
at Louisville, 1884; and the Industrial and Cotton Centennial
