and the civil forms, beginning with tlie chaotic state of the tribal 

 existence. 



Mr. J. P. Harrington, ethnologist, has obtained important corrob- 

 orative evidence of the validity of his discovery that there is a close 

 genetic relationship between Tanoan pueblo dialects of New Mexico 

 and the Kiowa. The bearings of this discovery on theories of the 

 origin of modern Pueblos is very significant. 



Special research work was done among the Salish Tribes, the Paw- 

 nee, and Chippewa. Dr. Walter Hough, curator of ethnology, 

 United States National Museum, undertook archeological work in the 

 A'Vhite Mountain Apache Eeserve, Arizona, and Mr. Neil M. Judd, 

 curator of American archeology, United States National Museum, suc- 

 cessfully investigated five prehistoric ruins in the Cottonwood Can- 

 yon caves. Dr. Ales Hrdlicka, curator of physical anthropology, 

 United States National Museum, was «^letailed to make an examina- 

 tion of the remains of southwestern Florida, especially of the shell 

 heaps along the coast south of Key Marco. Mr. Gerard Fowke has 

 made careful detailed study of the numerous caves in the Ozark 

 region of central Missouri, and also transmitted a valuable collection 

 of relics to the Museum. 



The number of publications distributed was 11,483, an increase of 

 4,139 over the number sent out last year. The library accessioned 

 380 new books and 210 pamphlets. 



INTERNATIONAL EXCHANGES. 



The total number of packages handled by the International Ex- 

 change Service during the year was 270,860, an increase over the 

 number for the previous year of 3,914. Although it has not yet been 

 possible to put the service on a prewar basis as far as the shipment of 

 consignments abroad is concerned, shipments in boxes are being made 

 as frequently as present conditions will permit to all countries except 

 Austria, Bulgaria, Germany, Hungary, Montenegro, Roumania, 

 Russia, Serbia, and Turkey. 



The exchange service has continued its policy of international 

 helpfulness in procuring publications desired by governmental and 

 scientific establishments both abroad and at home. As an instance of 

 this service, sets as nearly complete as possible of posters relating to 

 the war were assembled and transmitted to the British Museum at 

 their request, a similar service having been rendered to the French 

 Government the previous year. Owing to the excessive charges on 

 ocean freight, many packages were sent by mail. 



Late in the fiscal year shipments to Belgium and the northern 

 neutrals were resumed. The chief of the Belgian Service of Inter- 

 national Exchanges said, in part, in a letter to the office here:
