The author notes the California gold field on p. 470. He remarks in 

 conclusion : " 1. That, looking to the world at large, the auriferous 

 veinstones in the lower Silurian rocks contain the greatest quantity 

 of gold ; 2. That where certain igneous eruptions penetrated the Sec- 

 ondary deposits, the latter have been rendered auriferous for a limited 

 distance only beyond the junction of the two rocks ; 3. That the general 

 axiom before insisted upon remains: that all Secondary and Tertiary 

 deposits (except the auriferous detritus in the latter) not so specially 

 affected never contain gold."
