68 REPORT OF THE SECRETARY. 



he annually and regularly visited the Eocky Mountain region, first un- 

 der the auspices of the United States Exploring Expeditions of Warren 

 and Reynolds, and latterly under that of the IT. S. Geological Survey, 

 of which he became the executive officer when that organization first 

 took form, a position in which he remained up to the time of his death. 

 His capacity and integrity were valued not only by the officials of the 

 Survey, which he did so much in connection with, but by those of this 

 Institution, for which during thirty years he gathered in remote regions 

 specimens of natural history, geology, and ethnology, which are per- 

 manent testimonials of his enterprise and his industry. 



During the season of 1885 he was engaged in making an extended 

 search among the pueblos in the Moquis and Navajo districts of New 

 Mexico, and in this elevated country he was stricken by the dreaded 

 disease which lurks there. I met him in this region in 1887, when he 

 was already aroused, though too late, to a sense of his danger, and am 

 glad to recollect the circumstances of an acquaintance that associated 

 him with the regions of the West, in which so much of his life had been 

 passed, where so much valuable work was done, and where I had an 

 opportunity to learn something of his fertility of resource in emergency 

 and in the intimacy of camp life, of the amiable traits of his private 

 character. 



Mr. Stevenson's work was a double one, for he was equally at home 

 in cities, and especially in Washington, where he was extensively known 

 among members of Congress, and where the general confidence reposed 

 in him by them was a deserved tribute not merely to his skill but to 

 his personal integrity. 



Respectfully submitted. 



S. P. Langkley, 

 Secretary of the Smithsonian Institution.
