  relations 
  of 
  the 
  ore 
  bodies 
  at 
  and 
  near 
  Mineville, 
  may 
  first 
  be 
  given. 
  

   There 
  is 
  one 
  group 
  of 
  mines 
  based 
  on 
  a 
  large 
  faulted 
  and 
  folded 
  ore 
  

   body 
  in 
  the 
  village 
  of 
  Mineville 
  itself. 
  It 
  outcrops 
  at 
  about 
  the 
  

   1 
  200 
  and 
  1300 
  foot 
  contours 
  and 
  is 
  the 
  basis 
  of 
  several 
  distinct 
  

   mines, 
  some 
  of 
  which 
  are 
  no 
  longer 
  worked. 
  A 
  half 
  mile 
  to 
  the 
  

   northwest, 
  Barton 
  hill 
  rises 
  to 
  an 
  altitude 
  of 
  1880 
  feet 
  and 
  on 
  its 
  

   eastern 
  slope, 
  and 
  ranging 
  from 
  its 
  1300 
  contour 
  to 
  the 
  1750 
  is 
  a 
  

   long 
  diagonal 
  outcrop 
  with 
  many 
  pits. 
  The 
  group, 
  collectively 
  

   taken, 
  is 
  here 
  called 
  the 
  Barton 
  hill. 
  It 
  is 
  possible 
  that 
  this 
  bed 
  

   swings 
  around 
  to 
  the 
  east 
  under 
  the 
  drift 
  and 
  is 
  the 
  basis 
  of 
  the 
  two 
  

   Harmony 
  shafts, 
  south 
  of 
  the 
  Mineville 
  groups 
  [see 
  map: 
  fig. 
  6]. 
  

   Yet 
  there 
  is 
  still 
  much 
  uncertainty 
  about 
  this 
  connection. 
  

  

  At 
  the 
  north 
  end 
  of 
  the 
  Barton 
  hill 
  group 
  a 
  gap 
  of 
  concealed 
  and 
  

   drift-covered 
  fields 
  intervenes 
  with 
  no 
  demonstrated 
  ores. 
  After 
  

   half 
  a 
  mile, 
  ore 
  again 
  appears 
  in 
  two 
  bands 
  one 
  over 
  the 
  other, 
  at 
  

   the 
  openings 
  called 
  the 
  Fisher 
  hill 
  and 
  Burt 
  lot, 
  both 
  on 
  the 
  

   1600— 
  1640 
  contours 
  and 
  now 
  for 
  10 
  years 
  or 
  so 
  idle. 
  

  

  A 
  half 
  mile 
  east 
  of 
  Fisher 
  hill 
  and 
  on 
  the 
  1450 
  contour 
  of 
  another 
  

   hill, 
  is 
  the 
  recently 
  revived 
  Smith 
  mine, 
  whose 
  ore 
  body 
  is 
  tapped 
  

   still 
  lower 
  down 
  by 
  the 
  O'Neill 
  shaft. 
  Another 
  interval 
  ensues 
  to 
  

   the 
  north 
  and 
  then 
  after 
  half 
  a 
  mile 
  two 
  old-time 
  but 
  long 
  aban- 
  

   doned 
  mines 
  are 
  met, 
  called 
  the 
  Hall 
  and 
  the 
  Sherman. 
  The 
  former 
  

   is 
  one 
  of 
  the 
  oldest 
  in 
  this 
  locality 
  and 
  is 
  mentioned 
  by 
  Professor 
  

   Emmons. 
  Drilling 
  has 
  recently 
  been 
  in 
  progress 
  in 
  exploring 
  them, 
  

   but 
  no 
  mining 
  has 
  been 
  done 
  for 
  many 
  years. 
  Still 
  farther 
  north 
  

   no 
  ores 
  are 
  known 
  for 
  several 
  miles. 
  

  

  Mineville 
  group. 
  These 
  great 
  ore 
  bodies 
  are 
  the 
  chief 
  source 
  of 
  

   the 
  local 
  production, 
  and 
  they 
  present 
  a 
  mass 
  of 
  noble 
  proportions. 
  

   Thanks 
  to 
  the 
  liberal 
  spirit 
  and 
  courtesy 
  of 
  the 
  two 
  companies, 
  and 
  

   to 
  the 
  excellent 
  and 
  careful 
  records 
  of 
  the 
  engineers 
  they 
  can 
  be 
  so 
  

   well 
  illustrated 
  that 
  with 
  the 
  solitary 
  exception 
  of 
  the 
  Tilly 
  Foster 
  

   mine 
  in 
  Putnam 
  county, 
  they 
  give 
  us 
  the 
  best 
  idea 
  of 
  the 
  general 
  

   shape 
  and 
  relations 
  of 
  a 
  magnetite 
  body, 
  yet 
  afforded 
  in 
  this 
  country. 
  

   At 
  the 
  latter 
  the 
  structural 
  relations 
  are 
  simpler, 
  and 
  the 
  amount 
  

   of 
  ore 
  much 
  less. 
  The 
  Mineville 
  group 
  presents 
  a 
  very 
  violent 
  case 
  

   of 
  folding, 
  accompanied 
  by 
  stretching 
  and 
  pinching 
  of 
  the 
  crest. 
  

   The 
  ores 
  are 
  in 
  a 
  pitching 
  fold 
  which 
  makes 
  depth 
  rapidly 
  to 
  the 
  

   southwest, 
  so 
  that 
  we 
  have 
  to 
  keep 
  the 
  relations 
  constantly 
  in 
  mind 
  

   in 
  terms 
  of 
  solid 
  or 
  three-dimensional 
  geometry. 
  At 
  the 
  north 
  end 
  

   we 
  have 
  further 
  to 
  deal 
  with 
  a 
  series 
  of 
  faults 
  and 
  a 
  very 
  puzzling 
  

   relationship, 
  which 
  on 
  the 
  basis 
  of 
  one 
  bed 
  of 
  ore 
  is 
  not 
  easy 
  to 
  

   satisfactorily 
  clear 
  up.
