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. VICTOR MINDELEFF was engraved during the fiscal year in the
preparation of a report on the architecture of the Tusayan 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 traditionally
or historically with them. A comparative study is also made between the
Tusayan and Cibola groups and between them and certain well preserved
ruins in regard to constructive 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 prepared to
illustrate the report and give effect to the descriptions and
discussion.

Mr. COSMOS MINDELEFF 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 Cincinnati Industrial Exposition, 1884; the
Southern Exposition at Louisville, 1884; and the Industrial and Cotton
Centennial Exposition at New Orleans, 1884-'85. The report includes a
descriptive catalogue of the various exhibits. As these consisted
largely of models, and as the locality or object represented by each
model was described in detail, the report was lengthy. It was finished
in October and transmitted to the Commissioner representing the
Department of the Interior. During the remainder of the year the portion
of time which Mr. Cosmos Mindeleff was able to devote to office work was
employed in assisting Mr. Victor Mindeleff
