REPORT OF NATIONAL MUSEUM, 1915. 125 



Outside of ethnology the only exhibit of specimens consists of a 

 splendid group of the common elk or wapiti of the Rocky Mountain 

 region, comprising one individual each of the male, female and 

 young. The specimens were obtained in the Yellowstone National 

 Park, through the courtesy of the Secretary of the Interior, and were 

 mounted by Mr. James L. Clark, of New York. This preparation 

 was made in cooperation with the Biological Survey and is displayed 

 in the Palace of Agriculture. In order to illustrate the important 

 Museum exhibits in anthropology, biology and geology, an extensive 

 series of lantern slides was made to be shown by means of a stereo- 

 motorgraph machine. 



The parent institution and its other branches are all likewise rep- 

 resented by pictures, publications, charts, photographs, instruments, 

 and more especially by an exact reproduction of the Langley experi- 

 mental aeroplane which was successfully flown on the Potomac River, 

 near Quantico, Va., on May 6, 1896, the first demonstration of the 

 possibilit}^ of flight by a heavier than air machine. 



The representative of the Institution received the hearty coopera- 

 tion and assistance of all members of the staff in charge of the sub- 

 jects that are illustrated, and as regards the Museum the most exact- 

 ing duties in this respect naturally fell upon the head curator of 

 anthropology, Mr. Holmes, and the curator of ethnology. Dr. Hough. 

 At the time of the opening of the exposition, February 20, 1915, the 

 exhibits of the Institution and its branches had been entirely installed 

 and labeled. 



The Panama-California Exposition at San Diego, Cal., also de- 

 signed to celebrate the completion of the Panama Canal, was opened 

 on January 1, 1915, and will continue during the entire calendar 

 year. Its organization and maintenance are under local manage- 

 ment, and though combining many features, that in which the 

 Museum is most deeply interested is the illustration of man and his 

 progress from earliest prehistoric times to the present. This part 

 of the exhibition is housed in a permanent building and will be re- 

 tained perpetually as a museum for San Diego. "While not partici- 

 pating in this exposition in the same manner as at San Francisco, 

 the Institution and Museum have aided very materially in the as- 

 sembling of the anthropological collections, under plans drawn up 

 in cooperation with the exposition officials and Dr. E, L. Hewett, 

 director of exhibits. Two exhibits were prepared under the aus- 

 pices of the Institution and the Museum, and both were successfully 

 completed. The expenses were defrayed by the exposition, and 

 while the collections brought together were, in greater measure, to 

 become its property, a certain part of the material as well as the 

 scientific results of the necessary expeditions were to accrue to the 

 Institution.
