SURVEY  PUBLICATIONS  ON  GOLD  AND  SILVER. 
The  following  list  includes  the  more  important  publications  by  the  United  States  Goo- 
logical  Survey  on  precious  metals  and  mining  districts.  Certain  mining  camps,  while 
principally  copper  producers,  also  produce  smaller  amounts  of  gold  and  silver.  Publica- 
tions on  such  districts  will  be  found  in  the  bibliographies  for  copper  on  pages  144  and  145 
and  for  lead  and  zinc  on  page  166.  For  a  list  of  the  geologic  folios  in  which  gold  and  silver 
deposits  are  mapped  and  described,  reference  should  be  made  to  the  table  on  pages  8  and 
13  of  the  present  bulletin:
