where  the  schists  dip  east  at  75°  to  80°,  while  the  vein  dips  west  at 
about  the  same  angle.  Along  the  strike,  spurs  or  stringers  are  seen 
to  run  out  from  the  vein  into  the  schist  on  the  east  side  of  the  vein 
following  the  foliation.  The  vein  filling  is  silicified  and  is  inter 
leaved  with  films  of  quartz,  in  addition  to  which  there  are  streak; 
and  lenses  of  rather  massive  quartz.  Careful  panning  of  sample 
from  the  vein,  which  is  here  all  oxidized,  show  much  coarse  gold 
The  quartz  is  seldom  the  richest  ore,  and  the  best  material  usual! 
comes  from  its  contact  with  the  schists.  The  association  of  th 
coarse  gold  with  cellular  and  rusty  limonite  masses  indicates  iti 
derivation  from  pyrite  bunches.  No  pyrite  is  seen  in  the  tunne 
proper,  but  it  appears  in  the  bottom  of  the  winze. 
The   veins   on  this   property   cross  the  slopes   or   gently   incline 
table-land,  which  is  indented  by  the  branches  of  a  small  brook.     Til 
largest  vein  shows  a  great  outcrop  of  quartz,  forming  a  reef  Ihrjj 
extends  above  the  gentle  slopes  between  the  wagon   road   and   tic 
stream.     This  has  been  crosscut  by  open  cut  and  tunnel  and  shov 
that  the  quartz  does  not  extend  downward  as  a  solid  mass,  but  j 
streaks  and  fingers,  with  altered  schists  between.     Northward,  aero  . 
the  brook,  the  same  quartz  reef  is  exposed  in  an  old  cut,  now  ove 
grown  by  trees  10  to  15  years  old. 
The  Anderson  vein  lies  a  few  yards  east  of  the  one  last  mentione 
It  has  been  stripped  for  250  feet  north  of  the  brook,  and  is  expos<

The   Jenkins   vein   is   about   300   feet   east   of   the   Anderson, 
unopened,  unexplored  vein  lying  between.     The  Jenkins  vein  is  c 
veloped  by  a  vertical  shaft  10  feet  deep,  with  a  10-foot  crosscut  at  t 
bottom,  leading  to  a  20-foot  level  driven  on  the  vein.    The  vein  is  w 
defined,  has  a  smooth  wall,  with  crushed  schist  between  this  Avail  a, 
the  country  rock.     The  quartz  streak  varies  from  12  to  18  inches  jll8] 
thickness,  and  the  richer  samples  come  from  the  walls  of  this  stre 
Much  pyrite  is  seen  on  the  40-foot  level.     The  dip  is  east. 
The  Wabash  vein  lies  east  of  the  Jenkins.  It  is  developed  b} 
shaft  25  feet  deep,  with  15  feet  of  drifting  on  the  vein.  No  qua 
appears  on  this  vein,  but  it  carries  15  inches  of  gold-bearing  schist  I 
The  Hay  vein  to  the  north  is  exposed  by  a  shaft  45  feet  deep  2 
shows  8  feet  of  sheared  and  schistose  quartz.  This  evidence  seems

The  Bonanza  vein  shows  a  well-defined  lode  of  schist  ore  and  quai 
exposed  for  a  width  of  6  feet  by  a  shaft  12  feet  deep. 
The  Bell  vein  is  opened  on  the  ground  south  of  the  Governm 
road.  A  vertical  shaft  65  feet  in  depth  sunk  on  the  hanging  wal
