Introduction. 



Human Remains m California. — It is well known that implements and 

 human bones have been reported from beneath the great lava-flows which 

 cover many of the auriferous gravel deposits of California. From the same 

 gravels the partially fossilized bones of extinct quadrupeds have been ob- 

 tained, as well as many plants. The plants were regarded as Tertiary by 

 Lesquereux ; and some at least of the mammals, such as Rhinoceros hesperius, 

 are generally recognized as Pliocene, while others, for instance Mastodon 

 americanus, occur in the Quaternary if they are not confined to it. It was 

 held by Whitney that the gravels were Pliocene, and this view has met with 

 very general acceptance. The accumulation of the gravels and the eruption 

 of the flows of lava which forms the cap-rock preceded the glaciation of the 

 Sierra, a fact which lends strong support to the determination of age.
