fragments. This breccia is in masses sur- 

 rounded by a deposit of finer-grained agglom- 

 erate which is nearly a square mile in extent. 

 Other smaller masses of similar agglomerates 

 were found five miles southeast of Eoubaix. 

 These occurrences are remnants of larger 

 masses, for they have been subject to exten- 

 sive erosion. The original vents are not pre- 

 served but their stocks are now represented 

 by some of the dikes which occur at many 

 places in the schists or overlying Paleozoic 

 rocks. 



These facts suggest that the Black Hills 

 may have been the source of part if not all of 

 the large amount of the volcanic ash which 

 occurs intermixed and interbedded in the de- 

 posits of Oligocene age as well as in later 

 formations in various parts of South Dakota 

 and Nebraska.

INTERNATIONAL CONGEE SS OF PSEHIS- 



TOBIC ANTSSOPOLOG¥ AND 



ABCHEOLOGY 



The fourteenth International Congress of 

 Prehistoric Anthropology and Archeology was 

 held in the aiila of the university, Geneva, 

 September 9-14, 1912. On the evening of the 

 8th, Professor Eugene Pittard, president of 

 the congress, and Professor Edouard Naville, 

 honorary president, received the members in- 

 formally at the Atheneum. The attendance 

 was good throughout the week, 149 delegates 

 being present from 112 institutions represent- 

 ing at least 20 nations, 12 of which sent gov- 

 ernment delegates. A. Hrdlicka, George 

 Grant MacCurdy and Charles Peabody repre- 

 sented the United States government. The 

 total enrollment was nearly 600. 



It had been over sis years since the last con- 

 gress (Monaco) was held. In view of the im- 

 mense progress made in the domain of the 

 prehistoric during this time, the program was 

 exceptionally long and interesting. As no 

 provision had been made for a division of the 

 program into sections each treating a related 

 group of subjects, it was necessary not only 

 to limit each speaker to ten minutes, but also 



to abridge the discussion far beyond a desir- 

 able limit. Fortunately, however, many of the 

 papers were supplemented by generous exhib- 

 its of original specimens, casts, drawings, 

 plans, photographs, etc., for which the uni- 

 versity furnished suitable eases and ample 

 wall space conveniently located. The large 

 collection of original specimens from Spain 

 including remains of Elephas antiquus asso- 

 ciated with a Ohellean and perhaps pre- 

 Chellean industry, and the Celti-iberian sepul- 

 tures, exhibited by the Marquis of Cerralbo 

 deserve special mention. Other exhibitors, to 

 all of whom the thanks of the members pres- 

 ent are due will be indicated in the program 

 that is to follow. 



The following amendments to the constitu- 

 tion recommended at the Congress of Monaco, 

 were adopted at the first seance of the Geneva 

 Congress and went immediately into effect: 



The official language of the congress is French; 

 it is used for the publication of the proceedings 

 and the correspondence of the commission of 

 organization and of the committee. However, the 

 members of the congress may, in their letters, 

 communications or readings, make use of German, 

 English or Italian. Communications in these three 

 languages shall be accompanied by a rgsumg in 

 French, and the discussions before the congress 

 shall continue to be made in French. 



The maximum number of communications which 

 any author may enter on the program is limited 

 to four. 



At the same seance an anthropometric com- 

 mission consisting of the following members 

 was appointed to continue the work of unifi- 

 cation of anthropometric measurements begun 

 at the Congress of Monaco* and to report at 

 the close of the session: 



MM. Chantre (Prance), Ozekanowski (Eus- 

 sia), Duckworth (Great Britain), Prassetto 

 (Italy), Giuffrida-Euggeri (Italy), Godin 

 (France), Hillebrand (Hungary), Hoyos 

 Sainz (Spain), Hrdlicka (United States),

 many), MacCurdy (United States), Manouv-
