California, elevation of, during the Tertiary epoch; by T. A. 

 Conrad. Am. Jour. Sci., 1st ser., vol. 35, 1839, pp. 237- 

 251. 



In the author's article, "Notes on American Geology," in this jour- 

 nal, the author remarks : "On the coast of California ]Mr. Nuttall 

 found shells of recent species two hundred feet above the sea. These 

 are so much more remote from the axis of elevation than the Ter- 

 tiary shells of New York that the uplift of the Rocky ^Mountains 

 must have been far greater during the upper Tertiary period than 

 was any part of the Atlantic chain."
