ELEVENTH ANNUAL REPORT 



BUREAU OF ETHNOLOGY. 



By J. W. Powell, Director. 



INTKODUCTION. 



The prosecution of research among the North American 

 Indians, as directed b}' act of Congress, was continued during 

 the fiscal year 1889-'9U. 



The general plan on which the work has proceeded is that 

 explained in former reports. Briefly expressed, certain lines 

 of investigation are confided to persons selected for and trained 

 in their pursuit, and the results of their labors are presented 

 from time to time in the publications of the Bureau provided 

 for by law. A concise account of the work on which each 

 special student was actively engaged during the fiscal year 

 appears below, but this account does not enumerate all the 

 studies undei'taken or services rendered by them, because par- 

 ticular lines of research have been suspended in this, as in 

 former years, in order to complete certain investigations 

 regarded as of paramount importance. From this cause 

 delays have been occasioned in the issue of several treatises and 

 monographs, some of which are partly in type. 



The collaboration of explorers, writers, and students who 

 are not and may not desire to be officially connected with the 

 Bureau, is again solicited. Their contriljutions, whether in 

 the shape of suggestions or of extended communications, will 

 be gratefully acknowledged, and will always receive proper
