REPORT OF NATIONAL MUSEUM, 1914. 95 
curator, the varied activities connected with the building, modeling, 
casting, painting, repairing, cleansing, and poisoning of exhibits 
were carried on as usual. Mr. H. W. Hendley, for several years in 
charge of this laboratory, resigned on July 19, 1913, and was suc- 
ceeded by Mr. W. H. Egberts. Mr. R. A. Allen and Mr. T. W. 
Sweeny were engaged in the division of ethnology, while in the sev- 
eral other divisions the preparatorial work was attended to by the 
curators, with such assistance as was needed. The volume of work 
was greatly increased during the year, and much extra help required, 
on account of the preparation of extensive exhibits for the Panama- 
California Exposition and the Panama-Pacific Exposition, as well as 
of the exchange arrangement with Prof. C. V. Hartman, of the 
Naturhistoriska Riksmuseum, at Stockholm, Sweden. Mr. U.S. J. 
Dunbar modeled a large number of figures for the family and indus- 
trial groups; Mr. Hendley, subsequent to his separation from the 
Museum, modeled and painted, under contract, plaster figures for 
the historic costume exhibit; and Mr. Frank Micka made cases and 
painted numerous figures for the expositions. 
Exhibition collections —Steady progress was made with the exhi- 
bition collections, except in the division of graphic arts, where the 
renovation of the halls interrupted all operations. The more im- 
portant and effective results were in connection with history, period 
costumes, photography, and musical instruments. Permanent as- 
signment of space has now been arranged for most subjects, the 
exhibition material, so far as it can be supplied by the existing col- 
lections, has been in great measure selected, the cases are largely 
provided, and installation and labeling has been interrupted only by 
the preparation of exposition and exchange exhibits. 
Explorations —No member of the staff of the department found 
time to engage in field work, except that the head curator spent two 
days in visiting a very interesting aboriginal site near Luray, Va., 
on behalf of the Bureau of American Ethnology. Several joint 
expeditions of the Museum and the Panama-California Exposition, 
however, were conducted under the direction of the curator of the 
division of physical anthropology, as follows: 
Prof. K. Stolyhwo, director of the Anthropological Institute of 
Warsaw, Russian Poland, examined certain caves which the curator 
had previously visited on the Yenisei River in Siberia, with the view 
of obtaining traces of neolithic and possibly older human remains. 
The exploration, which was greatly interrupted by adverse climatic 
conditions, extended over six weeks, and, while failing to furnish 
skeletal remains of much value, it resulted in the acquisition of im- 
portant data and numerous very interesting archeological specimens. 
An investigation among the uncivilized tribes of southeastern Siberia, 
in charge of Dr. Stanislaw Poniatowski, chief of the Ethnologieal
