Archaeology and Ethnology. 
Mr. Clarence B. Moore has placed on exhibition in this department 
the material obtained on his expeditions during the year. 
Two additional exhibition cases were obtained by the William S. 
Vaux Fund for the display of the European archaeological material 
in that collection, chiefly from Scandinavia and Switzerland. 
Miss H. N. Wardle has cared for the collections during the year 
and rearranged portions of the display, preparing a number of new 
labels. 
Besides the material in the Vaux collection, the specimens in the 
Gottschall collection from the Frazer and Thompson Rivers, B. C., 
and from Washington, Oregon, Montana, and the Shasta tribes of 
California, have been catalogued and displayed. 
A rearrangement of some of the cases has added much-needed 
floor space and given uniformity of aspect.

Report of the Curator of the William S. Vaux Collections. 
During past year new cases have been purchased and installed, 
under the supervision of the Curators of the Academy, for the 
display of the archaeological collection. 
There have been few accessions to the mineral collection, as it 
has been considered advisable to defer any extensive purchases 
until the completion of the contemplated rearrangement. 
Respectfully submitted, 
F. J. Keeley, Curator Wm. S. Vaux Collection.
