feoLD.]  GOLD    PLACERS    OF    COAST    OF    WASHINGTON.  157 
Placer  mining  has  been  profitably  carried  on  in  the  beach  sands 
md  gravels  at  the  base  of  these  bluffs,  the  pay  sand  being  the  "  con- 
centrate "  from  the  material  which  is  continually  dropping  from  the 
Pace  of  the  cliff.  Water  being  abundant  at  this  place,  the  sluice-box 
nethod  is  used  entirely.  The  association  of  gold,  platinum,  iridos- 
nine,  garnets,  magnetite,  etc.,  is  the  same  at  this  locality  as  at  those 
3reviously  described.  No  estimate  of  the  output  of  this  district  or 
}f  the  pay  quality  of  the  placers  could  be  obtained,  as  at  the  time  of 
jhe  writer's  visit  the  workings  were  temporarily  deserted. 
Resume. — Placer  gold  mining  has  been  carried  on  since  1894  in  the 
>each  sands  at  different  points  along  the  west  Washington  coast  from 
ibout  10  to  23  miles  south  of  Cape  Flattery.  During  this  period  at 
east  $15,000,  and  possibly  much  more,  has  been  taken  from  the  dis- 
rict.     The  gold  is  derived  from  the  Pleistocene  sands  and  gravels, 
hich  cap  the  bluffs  along  this  portion  of  the  coast,  being  concen- 
rated  on  or  near  the  bed  rock  at  the  base  of  the  bluffs  by  the  action 
f  the  waves.  The  gold  is  accompanied  by  small  amounts  of  platinum 
nd    iridosmine,    the    three    being    associated    Avith    magnetite    and 
ruby  "  (garnet)  sand  and  small  quantities  of  pyrite.  Mining  is 
arried  on  principally  by  the  sluice-box  method,  although  where  the 
ater  supply  is  limited,  as  at  the  locality  2  miles  north  of  the  mouth 
f  the  Ozette,  rockers  are  used.
