of the Chinook jargon, for aid in the preparation of Chinookan bibliography; and 

 Mr. Pilling acknowledges equal obligations to the Rev. Myron Eells and Dr. Franz 

 Boas for information concerning the Chinookan and Salishan languages. 



SYNONYMY OF INDIAN TRIBES. 



The preparation of this work, which has engaged the attention of nearly all the 

 collaborators of the Bureau at various times, is well advanced. During the year 

 Messrs. H. W. Henshaw, F. Webb Hodge, James Mooney, and J. Owen Dorsey have 

 contributed to the work. The portions of the synonymy relating to the tribes of 

 the following stocks are ready for publication: 



Attacapan, Beothukan, Kalapooian, Karankawan, Kusan, Lutuamian, Muskho- 

 gean, Natch esan, Skittagetan, Titnuquauan, Tonikan, Ucbean, Yakonan, and Ynman. 



In addition, the Algonquian and Iroquoian families — two of the largest and most 

 important — require comparatively little elaboration by Mr. Mooney (to whom these 

 stocks were originally assigned) to make them ready for press. 



When his other duties permitted Mr. Hodge devoted attention to the elaboration 

 of material pertaining to the Piman family, as well as that of the Pueblo stocks 

 (Zunian, Keresan, Tafioan, and the Tusayan division of the Shoshonean). Very 

 little work is now required to finally complete for publication the material 

 relating to these tribes. In addition, Mr. Hodge introduced into the descriptions 

 formerly made of some twenty stocks (principally in California) a large body of 

 new material made known by recent investigators. 



PSYCHOLOGY. 



Within recent years it has come to be recognized by many ethnologists that the 

 mythic concepts, and through these the social institutions, of primitive peoples are 

 dependent on a limited number of factors, including (1) individual and tribal envi- 

 ronment and (2) individual and collective modes and habits of thought. Now the 

 first of these factors has received the attention of nearly all investigators, while the 

 second has received much less consideration and is frequently ignored. Accordingly, 

 it has been thought desirable to undertake the investigation of intellectual method 

 for the purpose of developing the principles of psychology, and thus affording a more 

 definite basis for the researches in mythology and sociology. To this subject the 

 Director has devoted a considerable part of the year, and a tentative system of psy- 

 chology which will, it is believed, prove a useful guide for further researches has 

 been formulated. 



EXPLORATION. 



The Director spent several weeks in ethnologic exploration in the Northern Pacific 

 slope. The territory lying between the Sierra Nevada Mountains and the Pacific i» 

 of exceptional value to ethnologists by reason of the remarkable number of independ- 

 ent linguistic stocks crowded into a relatively small area; three-fourths of the dis- 

 tinct groups of peoples in this country, and fully half of all known on the Western 

 Hemisphere, are found in this locality. The northern part of the tract has never 

 been explored by students; and in the hope of discovering additional stocks among 

 the remaining tribes, and in the hope of gaining additional knowledge concerning the 

 origin of this remarkable diversity of languages, an exploratory trip was planned. 

 The results of tne observations are incorporated in reports now in course of prepara- 

 tion for the press. Mr. Henshaw, in southern California, and Mr. Mooney, in the 

 northern Rocky Mountain region, also penetrated areas and encountered Indians not 

 previously seen by scientific students. 



MISCELLANOUES WORK. 



As incidentally noted in proceeding paragraphs, much time and thought have 

 been given to the installation of an ethnologic exhibit in the World"s Columbian 

 Exposition at Chicago. This exhibit occupies the southern portion of the Govern-
