REPORT OF THE SECRETARY. 63 



the tribes of Alaska, the western half of Washington Territory, and 

 North western Oregon, and is accompanied by maps exhibiting the 

 geographic distribution of the tribes of these regions. A second volume 

 on the tribes of California has also been sent to the Government Printer, 

 which will be succeeded by others as rapidly as they can be prepared. 



Dr. Elliott Coues, U. S. A., is engaged on a " Eeport on the Birds of 

 the Valley of the Colorado," based primarily on the collections made by 

 the several parties under Professor Powell's direction. This report was 

 sent to the Government Printer early in the spring, and about 200 pages 

 have already been set up. 



Mr. L. F. Ward, the botanist of the corps, assisted by several gentle- 

 men of scientific ability in this department, has been engaged during 

 the entire year in the preparation of a "Report on the Botany of the 

 Valley of the Colorado," which is now nearly ready for publication. 



CONCLUSION. 



From the foregoing report I trust it will be evident to all inter- 

 ested in the prosperity of the Institution that the establishment is still 

 successfully prosecuting the plan best adapted to realize the intentions 

 of its founder, that its funds are in a good condition, and that its repu- 

 tation and usefulness have suffered no diminution since the date of the 

 last report. 



Respectfully submitted. 



JOSEPH HENRY, 

 Secretary Smithsonian Institution. 



Washington, January, 1877.
