SIERRA CLUB BULLETIN, VOL. IX. PLATE LXXIV. 



CAPTAIN JOSEPH REDDEFORD WALKER. 



No portrait of Walker has hitherto been published so far as known to the 

 writer. He is buried in Martinez Cemetery, and the date of his over-night camp in 

 Yosemite Valley is taken from the monument over his grave. The portrait is from 

 a daguerreotype in possession of Mrs. Mary Vaughan Walker, of Walnut Creek, 

 California, by whose courtesy the reproduction is made. 



Various rare books, maps and manuscripts in the Bancroft Collection of the 

 University of California Library have been consulted. 



For assistance in locating rare books, map's and manuscripts acknowledgments 

 are made to jNIr. H. I. Priestley, Assistant Curator of the Bancroft Collection.
