Minerals. 
During the past year the concentration of the mineral and rock 
collections in the new quarters was completed. The collection of 
the Second Geological Survey of Pennsylvania was brought up 
from the basement and placed on the first floor, where the specimens 
are readily accessible, while the rock collection was removed to the 
second floor. A room in the basement has been assigned for the 
storage of the First Geological Survey collection, the duplicates of 
the Second Survey, and the Woolman collection of New Jersey well 
records. 
A small hand lap has been installed for grinding thin sections. 
Among the more important accessions of the year were specimens 
of the Mt. Joy and Cumberland Falls meteorites, and a collection 
of American rocks, which were obtained from the U. S. National 
Museum by exchange; and a collection of stalactities and stal¬ 
agmites from the Redington cave, Northampton County, Pennsyl¬ 
vania. 
During the spring, Mr. Gordon spent three weeks studying the 
chromite deposits and albite pegmatites of southern Pennsylvania 
and Cecil County, Maryland. During the summer a collecting 
trip was taken through Virginia, the itinerary including the Amelia 
mica mines, Irish Creek tin mines, and the Midvale, Rockbridge 
County, durrenite locality. The rest of the summer was spent 
in visiting localities in Pennsylvania; and in studying the Ordovi¬ 
cian diabases and basalts of Lebanon County. 
Archaeology. 
Miss H. Newell Wardle, in charge of this department, reports 
that the Archaeological and Ethnological collections, having now 
reached the limits of congestion, no further additions can be made 
to the general exhibit* until new cases are procured. Two small 
c<ises in the adjoining room, having been placed at the service of 
the department, have been devoted to the temporary display of 
recent additions to the collection and special exhibits of specimens, 
hitherto stored. It is designed to change their contents period¬ 
ically. 
Progress has been made in the sorting, cataloging, and care of 
the Gottschall collection of North American Indian material. 
Mr. Clarence B. Moore was again compelled to forgo his usual 
autumn expedition to the southern states. His spring expedition 
to the Florida west coast and keys resulted in the discovery of 
new types of aboriginal shell-implements.
