Brown 200 in Bermuda; 1,300 others were received from various 

 donors. Messrs. Long and Van Pelt have voluntarily assumed care 

 of the local herbarium, and some 4,000 specimens were added during 

 the year. Mr. Van Pelt has devoted his time to poisoning and 

 mounting the material, while Mr. Long has done much local field 

 work, critically studied the material and identified and lal)elled it. 



Dr. Stone spent some time in arranging and sorting the lower 

 orders in the Porter herbarium preparatory to having the specimens 

 mounted. 



Specimens have been loaned for scientific study to Messrs. K. K. 

 McKenzie, J. K. Small, Harold St. John, C. S. Sargent and M. L. 

 Fernald. 



Minerals and Rocks. 



The Curator of the William S. Vaux Collections, Mr. F. J. Keeley, 

 reports that Mr. Samuel G. Gordon, a student on the Jessup Fund 

 during the year has completed the cataloguing of the minerals. 

 Thirteen additions have been made during the year. The collection 

 now numbers 8,193 specimens. The catalogue of the general Acad- 

 emy collection has also been brought up to date and comprises 

 8,508 entries. This collection has been rearranged by Mr. Gordon 

 in trays under the cases in the archaeological hall, in accordance 

 with Dana's classification (sixth edition) , and is thus easily accessible 

 for study or consultation. 



The local collection of minerals was thoroughly cleansed and 

 rearranged geographically. While lacking a number of local minerals, 

 it is good representative collection. 



All the rocks stored in various parts of the north museum building 

 have been brought together and arranged in temporary cases of 

 drawers by Mr. Gordon, following Rosenbusch's system, so that 

 they may be easily consulted. 



Archeology and Ethnology. 



In this department the material obtained by Mr. Clarence B. 

 Moore's expeditions has been placed on exhibition under his direction. 



Two cases were procured for the display of portions of the Wm. S. 

 Vaux Collections, which have been withdrawn from exhibition for 

 several years, owing to changes in the hall during alterations. 



Two other cases were installed for exhibiting portions of the 

 Pueblo pottery and basketry contained in the Gottschall Collection. 

 This collection, comprising about 5,000 specimens, was presented
