EDITORIAL NOTE. 



IN about the year 1885 Mrs. M. D. Lincoln undertook the prep- 

 aration of a biography of Major Powell, and from time to time 

 during several years busied herself with the gathering of material. 

 Her most important source was Major Powell himself, and through 

 a series of interviews she obtained the events of his early and 

 middle life as they were preserved in his memory. In some of 

 those interviews she wrote down his words, and her manuscript as 

 finally completed contains much of his characteristic phraseology. 

 In a sense, therefore, and to a certain extent, the relation is auto- 

 biographic. 



Her work covered his early life and military career, but she 

 did not feel competent to treat of his scientific labors and attain- 

 ments, and for this subject appeal was made to Mr. G. K. Gilbert, 

 member of the Geological Survey, who wrote two further chap- 

 ters on Major Powell's scientific career. This was in 1888. 



Since Major Powell's death, Mr. Gilbert has revised his manu- 

 script so as to cover the later as well as earlier scientific work ; 

 and two chapters have been added, one by Mr. Marcus Baker, and 

 another by the editor of The Open Court. 



All these tributes to our late friend appeared in The Open 

 Court, December, 1902, to June, 1903, and are here reprinted, 

 with slight revision.
