years of search for fossils in the gold rocks, by means of which their age 
pnaitt be determined, those which he exhibited were the first he had 
n able to obtain, and that his attention had been called to these and

fossils, and that the Survey had “ found fossils in the rocks associ- 
any with gold along a line nearly 300 miles in length, extending from 
Pitt River to the Mariposa Estate,” os (For synopsis of these remarks, 
see Proc. Cal. Acad. Nat. Sci., ili, p. 198). I described minutely the 
Genesee Valley localities for Jurassic, Triassic, and Carboniferous fossils,

Secondary age from Genesee Valley, in the northern part of the State,
