  on 
  Palmer 
  hill, 
  but 
  most 
  are 
  much 
  thinner. 
  They 
  have 
  little 
  effect 
  

   upon 
  the 
  ore 
  and 
  except 
  where 
  accompanied 
  by 
  faulting 
  which 
  is 
  

   rare 
  they 
  do 
  not 
  materially 
  interfere 
  with 
  mining 
  operations. 
  From 
  

   the 
  few 
  examples 
  that 
  have 
  been 
  examined 
  petrographically, 
  they 
  

   appear 
  to 
  be 
  all 
  ordinary 
  diabases. 
  

  

  Arnold 
  hill 
  mines 
  

  

  The 
  mines 
  on 
  Arnold 
  hill 
  comprise 
  several 
  separate 
  openings 
  

   located 
  along 
  the 
  southern 
  shoulder 
  of 
  the 
  ridge. 
  The 
  ore 
  bodies 
  

   outcrop 
  in 
  parallel 
  series 
  or 
  en 
  echelon 
  with 
  a 
  general 
  trend 
  of 
  n. 
  20 
  

   e. 
  Altogether 
  they 
  have 
  been 
  explored 
  for 
  a 
  mile 
  and 
  a 
  half 
  along 
  

   the 
  strike, 
  though 
  of 
  course 
  not 
  continuously. 
  Beginning 
  at 
  the 
  

   south 
  end, 
  the 
  first 
  opening, 
  known 
  as 
  the 
  Finch 
  pit, 
  lies 
  at 
  about 
  

   the 
  850 
  foot 
  contour. 
  Next 
  in 
  order 
  to 
  the 
  north 
  after 
  a 
  short 
  

   interval 
  are 
  several 
  open 
  cuts, 
  parallel 
  but 
  at 
  slightly 
  different 
  

   horizons, 
  extending 
  perhaps 
  500 
  feet. 
  They 
  have 
  long 
  since 
  ceased 
  

   to 
  be 
  productive. 
  The 
  Arnold 
  or 
  Big 
  mine, 
  with 
  three 
  ore 
  bodies, 
  

   is 
  about 
  1000 
  feet 
  farther 
  north, 
  and 
  at 
  about 
  an 
  equal 
  distance 
  

   from 
  the 
  Arnold 
  is 
  the 
  Nelson 
  Bush 
  mine 
  with 
  its 
  two 
  shafts, 
  the 
  

   last 
  to 
  be 
  worked. 
  The 
  small 
  Chalifou 
  pit 
  lies 
  to 
  the 
  south 
  and 
  east 
  

   of 
  the 
  main 
  group. 
  

  

  According 
  to 
  local 
  records 
  the 
  earliest 
  discovery 
  on 
  Arnold 
  hill 
  

   was 
  made 
  in 
  1806. 
  Mining 
  was 
  begun 
  on 
  a 
  small 
  scale 
  shortly 
  after 
  

   that 
  date, 
  and 
  in 
  181 
  2 
  the 
  property 
  was 
  purchased 
  by 
  Arnold, 
  

   Stickney 
  & 
  Howe 
  who 
  continued 
  in 
  possession 
  for 
  over 
  50 
  years. 
  

   Up 
  to 
  the 
  time 
  of 
  Emmons's 
  report 
  (1842) 
  exploitation 
  was 
  con- 
  

   fined 
  to 
  the 
  southern 
  deposits 
  which 
  he 
  states 
  were 
  then 
  being 
  

   worked 
  under 
  lease 
  . 
  The 
  mines 
  have 
  been 
  intermittently 
  active 
  dur- 
  

   ing 
  the 
  last 
  half 
  century. 
  The 
  most 
  recent 
  undertaking, 
  the 
  Arnold 
  

   Mining 
  Co., 
  reopened 
  the 
  Nelson 
  Bush 
  mine, 
  working 
  it 
  for 
  a 
  period 
  

   of 
  three 
  years. 
  A 
  mill 
  of 
  200 
  tons 
  daily 
  capacity 
  was 
  erected 
  at 
  

   Arnold 
  Station 
  (Ferrona 
  on 
  the 
  map) 
  and 
  new 
  mining 
  equipment 
  

   installed. 
  The 
  company 
  ceased 
  operations 
  in 
  the 
  summer 
  of 
  1906. 
  

  

  Geological 
  relations. 
  The 
  deposits 
  outcrop 
  as 
  rather 
  thin 
  bands 
  

   intercalated 
  in 
  the 
  gneiss 
  parallel 
  to 
  its 
  foliation. 
  Their 
  dip 
  is 
  

   toward 
  the 
  west 
  and 
  steep 
  generally 
  70 
  or 
  a 
  little 
  more. 
  Their 
  

   shape 
  which 
  is 
  tabular 
  has 
  been 
  modified 
  by 
  compression, 
  produc- 
  

   ing 
  undulations 
  and 
  pinches 
  both 
  along 
  the 
  strike 
  and 
  dip 
  ; 
  on 
  the 
  

   north 
  end 
  the 
  irregularities 
  seem 
  to 
  be 
  more 
  pronounced 
  than 
  else- 
  

   where 
  and 
  the 
  lenticular 
  form 
  is 
  the 
  characteristic 
  one. 
  

  

  The 
  deposits 
  have 
  been 
  subjected 
  to 
  faulting 
  on 
  a 
  small 
  scale. 
  

   The 
  direction 
  of 
  movement 
  is 
  across 
  the 
  strike,
