REPORT OF THE HEAD CURATOR OF THE 

 MUSEUMS AND HERBARIUM 



Dr. N. L. Britton, Director-in-Chief. 



Sir: I have the honor to submit the following report for 

 the year 1910. 



The collections in my care were conserved by methods 

 adopted heretofore. They were developed along the 

 usual lines, and were increased as follows: 



By gifts and purchases 6,941 sp< 



By exchanges 9,755 sp< 



By exploration 25,995 s P eci 



Thus an aggregate of 42,691 specimens was added to 

 the collections of the Museums and Herbarium. 



A total of 4,922 duplicate specimens was sent to other 

 institutions and individuals in exchange. 



Museums 



The Fossil Plant Museum received attention along two 

 main lines; first, the replacing of specimens already on 

 exhibition by individual specimens better adapted to il- 

 lustrate features of interest, second, the study and labeling 

 of unnamed material, and the further cataloguing of the 

 type specimens. The public exhibit in the floor cases has 

 been completely furnished with exhibition blocks, and 

 nearly all the specimens with printed labels. The addi- 

 tions to this collection were mostly from North America. 



The Economic Museum was increased chiefly by the 

 installation of three large collections; the first a series of 

 the food-plants of the western United States, the second a 

 series of the food-plants of Mexico, and the third a series 

 of miscellaneous drug-plants from all parts of the globe. 

 Miscellaneous economic specimens, which were largely 

 secured on the Garden's exploring expeditions, were also 

 added throughout the museum.
