REPORT OF THE SECRETARY 39 



Through the cooperation of the United States Treasury Depart- 

 ment, a number of valuable United States and foreign coins and 

 medals have been added to the numismatic collections. Of special 

 interest in this connection has been the transfer from the Treasury 

 Department to the Museum of about 800 publications, forming a 

 highly useful library, on the subject of numismatics. 



The portrait collection was increased by the following additions: 

 A portrait of Elizabeth Cady Stanton by Anna E. Klumpke was 

 presented by the National American Woman's Suffrage Associa- 

 tion; portraits of Gen. John J. Pershing and Marshal Ferdinand 

 Foch were presented by the artist, Victor Perard. A portrait of 

 President Warren G. Harding, by John Innes, showing the former 

 delivering an address at Stanley Park, British Columbia, July 29, 

 1923, was presented to the Museum by the National Press Club, 

 Washington, D. C. 



EXPLORATIONS AND FIELD WORK 



The greater part of the material added to the collections during 

 the current year w^as as usual derived from expeditions and ex- 

 plorations under the auspices of private organizations and Govern- 

 ment agencies. 



In biology the National Geographic Society was a large con- 

 tributor through its expeditions in China, in the Arctic, and in this 

 country. From the former extremely valuable and extensive col- 

 lections, comprising some 68,000 plants, over 1,600 birds, 60 mam- 

 mals, and other specimens, were received from the society's expedi- 

 tion under Dr. Joseph F. Rock, principally from the Province of 

 Yunnan. The bulk of the material collected by the society's expedi- 

 tion under INIr. F. li. Wulsin, which has been referred to in previous 

 reports, was received during the past fiscal year. It comprised im- 

 portant and extensive collections of birds, mammals, reptiles, and 

 fishes from inner INIongolia, the Alashan Desert, and Western Kaiisu, 

 in the region of Lake Kokonor, northeastern Tibet, as well as from 

 the Min Sha Range, which marks the boundary between the 

 Provinces of Kansu and Szechwan. The specimens from this source 

 are of particular importance, since they afford topotypes of numer- 

 ous species described from Przevalski's famous exploring trip of 50 

 years before. They also include important ethnological material 

 from a region not heretofore represented in this institution. The 

 collections from these sources supplement those made by Mr, R. S. 

 Clark and Mr. Arthur deC. Sowerby in 1908-9 in Kansu, Thansi, 

 and Shensi, and the important collections made during the past 

 year by Rev. David C. Graham in Szechwan. The latter were 

 secured on a difficult trip to Songpan and the Yellow Dragon Gorge,
