REPORT OF NATIONAL. MUSEUM, 1924 7 



Museum, and a quantity of foreign material was acquired through 

 gifts and exchanges. A slab of fossil footprints from the Triassic 

 shales of Virginia, received through the courtesy of F. C. Littleton, 

 was added to the exhibition series. 



Ethnological material collected in the Philippines by the late Capt. 

 E. Y. Miller was donated by Mrs. Florence G. Miller, and South 

 American Indian relics were contributed by D. S. Bullock. In 

 American archeology should be mentioned an especially valuable 

 collection of. ancient decorated earthenware bowls from Mimbres 

 Valley, N. Mex., transferred from the Bureau of American Ethnology, 

 and a loan by Victor J. Evans of excellent ancient Casas Grandes 

 pottery. Prehistoric antiquities from ancient sites in France, Bel- 

 gium, and Germany, collected by Dr. Ales Hrdlicka, enriched the 

 Old World archeological series. To the large series illustrating the 

 development of the pianoforte which he is building up in the 

 Museum, Hugo Worch added three rare instruments. In physical 

 anthropology the most notable receipt was a large number of skeletal 

 remains from early historic Arikara Indian village sites near 

 Mobridge, S. Dak. An exhibit illustrating the most important relics 

 of ancient man and showing in part the field of man's physical varia- 

 tions was installed in the west north range, first floor, of the Natural 

 History Building. The subject of physical anthropology had before 

 been but inconspicuously illustrated in the exhibition halls. 



The glass industry exhibit was brought considerably closer to com- 

 pletion through the generosity of the Corning Glass Works in sup- 

 plying two models of recent types of melting furnaces and typical 

 examples of glassware. A complete working unit of the Strowger 

 automatic telephone system, contributed by .the Automatic Electric 

 Co., enabled the Museum to equip an exhibition case with three 

 telephone instruments which the visitor may operate and at the 

 same time observe the functioning of the various parts. The ad- 

 vance in motor construction was illustrated by the donation by the 

 Cadillac Motor Co. of one of its first automobiles, made in 1903, and 

 a chassis of its 1923 model, the latter being so sectioned as to display 

 parts ordinarily hidden from view. 



The monoplane, Fokker T-2, which flew in May, 1923, from New 

 York to San Francisco in a nonstop flight of less than 27 hours, was 

 added to the aircraft exhibit, as was also a heliocopter type of air- 

 plane successfully used in 1923 by Emile Berliner and his son at 

 College Park, Md. The watercraft collections were materially 

 enhanced by models of the steamships Leviathan and Empress of 

 Russia, the latter one of the vessels of the Canadian Pacific Railway 

 Co. plying between Vancouver and the Orient.
