 of the southwestern United States were the subject- of investigation 

 by Doctor and Mrs. Vohiey Spaulding, of Tucson, Arizona, and 

 plants of California by Miss Alice Eastwood, of the California 

 Academy of Sciences. Mr. W. AV. Eggleston, of Rutland, Vermont, 

 made several visits to examine specimens of Crataegus. The bota- 

 nists of the Department of Agriculture made constant use of the 

 herbarium. 



About 2,800 specimens, the largest number since 1904, were lent 

 to botanists outside of the government service, both in the United 

 States and Europe. The principal sendings were as follows: One 

 thousand and sixty-seven specimens of Xyctaginacese to Mr. Paul 

 C. Standley, of the New Mexico College of Agriculture; 440 ferns 

 of the genus Dryopteris to Mr. C. Christensen, of the Botanical 

 Museum, Copenhagen ; 190 specimens of the genus Wissadula to Prof. 

 R. E. Fries, of the Botanical Museum, Upsala ; and 153 specimens,

DEPARTMENT OF GEOLOGY. 



The total number of geological and paleontological specimens ac- 

 quired during the year was nearly 33,000, comprised in 147 accessions. 

 Twenty lots of specimens were lent to investigators for study, 149 

 sets of duplicates were distributed to educational establishments, and 

 15 lots of duplicates were used in making exchanges. Twenty-two 

 papers by members of the stafl:' and by others descriptive of material 

 belonging in the department were published. The}- are cited in the 

 bibliography. As explained elsewhere, the division of stratigraphic 

 paleontology was separated into three divisions, corresponding with 

 former sections, as follows: Invertebrate paleontologj^, vertebrate 

 paleontology, and paleobotany. 



Systematic and applied geology. — The most important accessions 

 to this division were as follows: By transfer from the U. S. Geolog- 

 ical Survey, specimens of rocks from the Rockland quadrangle, 

 Maine, the Austin and Brackett quadrangles, Texas, and the Redding 

 quadrangle, California, and rocks and ores from the Coeur d'Alene 

 district, Idaho; as gifts from Mr. Charles P. Robbins, the Southern 

 Railway, and the Utah Antimony Company, respectively, examples 

 of tin ores from Spokane, Washington, of copper ore from Ducktown, 

 Tennessee, and of antimony ores from Utah. 



Xo noteworthy changes were made in either the exhibition or study 

 series. The former is as extensive as the space will permit, and is 

 fully catalogued and labeled. The dust occasioned by the rebuilding 

 of the roofs rendered necessary the thorough cleaning and overhaul-
