room, the deSchweinitz and other historic collections being arranged 
in a fireproof vault which had been erected there. The north room 
has been fitted up for the mounting and preparation of specimens. 
During the year, Miss Ada Allen, who has continued as an aid in 
the department, has mounted upwards of 3700 sheets of specimens 
comprising the remainder of the Joel Carter herbarium exclusive of 
the local material, 302 specimens from California, and 613 sheets of 
New England plants both of which were received by purchase. Most 
of these have been catalogued by Mr. Brown and distributed. Much 
additional time was spent in the general arrangement of the herbar¬ 
ium in its new quarters. 
Mr. Bayard Long has spent much time in the critical study of 
various groups in the local herbarium and in its general supervision. 
Much use has been made of the herbarium by visiting botanists 
and specimens have been loaned to C. A. Wetherby, M. L. Fernald, 
W. B. Maxon, C. Schneider, A. L. Grant and F. L. Stevens. 
Minerals and Rocks. 
The change of location in this department to rooms adjacent to the 
exhibition collections of minerals has been very advantageous as it 
brings all of the mineralogical and geological material into close as¬ 
sociation where it is readily available for consultation. 
The collection of Pennsylvania minerals has been transferred to 
the gallery of the mineral hall formerly occupied by the State Depart¬ 
ment of Health exhibit, where there is abundant room for its ex¬ 
pansion. 
The Curators are again indebted to Mr. Frank J. Iveeley, curator of 
the William S. Vaux Collections, and to Mr. Samuel G. Gordon, a 
student of the Jessup Fund, for all the attention that has been given 
to this department. Mr. Gordon has cared for the various accessions 
and has completed an examination of the old collections and dupli¬ 
cates stored in the building, preparing the latter for gift or exchange 
to other institutions. He has also made a number of field trips to 
various counties in Pennsylvania and obtained many specimens of 
great value to the State collection. 
Archeology. 
Miss H. N. Wardle, who has cared for the collections in this depart¬ 
ment, reports that considerable shifting of exhibits has been necessary 
to make room for accessions or the display of material not hitherto 
on exhibition, many specimens from the A. H. Gottschall collection 
of North American Indian material having been thus displayed.
