Sierra Club Bulletin. 



NOTES AND CORRESPONDENCE. 



In addition to longer articles suitable for the body of the magazine, the 

 editor would be glad to receive brief memoranda of all noteworthy trips or 

 explorations, together with brief comments and suggestions on any topics of 

 general interest to the Club. Descriptive or narrative articles, or notes 

 concerning the animals, birds, Ush, forests, trails, geology, botany, etc., of 

 the mountains, will be acceptable. 



The oMce of the Sierra Club is Room 402 Mills Building, San Francisco, 

 where all Club members are welcome, and where all the maps, photographs, 

 and other records of the Club are kept. 



The Club would like to secure additional copies of those numbers of the 

 Sierra Club Bulletin which are noted on the back of the cover of this 

 number as being out of print, and we hope any member having extra copies 

 will send them to the Secretary. 



Professor George Davidson. 



In 1850 a young astronomer came to San Francisco. He had 

 been engaged in geodetic work in the East, particularly in the 

 Coast Survey under Bache. To him was assigned the duty of 

 determining the latitude and longitude of the headlands, islands, 

 rocks and harbors of the Pacific Coast from the Mexican bound- 

 ary north. One would think that this was work enough for any 

 geodesist; but George Davidson not only completed the work 

 with the utmost fidelity and rarest precision; but somehow found 

 time also to write the "Coast Pilot." It was a self-imposed task 

 and required years of effort; but the book is an imperishable 

 monument to his professional knowledge and his untiring industry. 



In one of his late volumes he refers to himself as "one who 

 has enjoyed opportunities that will not fall again to the lot of 

 one man." He could justly say this, for he had then given fifty- 

 seven years of service and was to round it out to sixty. 



More than 200 memoirs came from his pen, all of them genuine 

 contributions to knowledge. He received many honors from 

 learned bodies at home and abroad. In 1909 the American 

 Geographical Society bestowed the Daly medal upon him for 

 "Fifty years of distinguished work in Geodesy." Few men of 

 science have received wider recognition and few lives have been 

 so filled with work for the good of the community. 



At the time of his death, he was Honorary Vice-President of 

 this Club, and had been for many years previous one of its 

 Directors.
