  now 
  know 
  that 
  this 
  ore 
  continues 
  downward 
  lower 
  than 
  was 
  for- 
  

   merly 
  shown. 
  More 
  recent 
  data 
  also 
  show 
  that 
  in 
  No. 
  7, 
  rock 
  cuts 
  

   off 
  the 
  ore 
  on 
  the 
  east, 
  apparently 
  before 
  the 
  upward 
  curve 
  of 
  the 
  

   ore 
  was 
  found 
  and 
  a 
  fault 
  is 
  suggested. 
  

  

  In 
  its 
  western 
  prolongation 
  as 
  shown 
  in 
  sections 
  8-12, 
  Old 
  Bed 
  

   encounters 
  faults, 
  and 
  an 
  area 
  of 
  broken 
  ground 
  with 
  one 
  or 
  two 
  

   disconnected 
  masses 
  of 
  iron-stained, 
  apatite-bearing 
  ore 
  called 
  

   11 
  Red 
  Ore." 
  The 
  red 
  color 
  is 
  due 
  to 
  the 
  crush 
  and 
  to 
  the 
  conse- 
  

   quent 
  alteration 
  of 
  some 
  of 
  the 
  minerals. 
  In 
  the 
  slides 
  the 
  color 
  

   is 
  clearly 
  shown 
  to 
  be 
  caused 
  by 
  red 
  hematite 
  infiltrations 
  into 
  

   cracks. 
  The 
  source 
  of 
  the 
  iron 
  oxid 
  is 
  without 
  doubt 
  decomposed 
  

   pyroxene 
  crystals. 
  

  

  Beyond 
  the 
  " 
  Red 
  Ore 
  " 
  lies 
  the 
  Miller 
  pit, 
  a 
  very 
  large 
  and 
  very 
  

   interesting 
  ore 
  body, 
  now 
  practically 
  worked 
  out. 
  The 
  Miller 
  is 
  

   presumably 
  the 
  faulted 
  extension 
  of 
  the 
  Old 
  Bed, 
  which 
  is 
  dropped 
  

   to 
  the 
  west, 
  but 
  it 
  has 
  in 
  sections 
  7-10 
  a 
  very 
  peculiar 
  double 
  char- 
  

   acter. 
  The 
  separate 
  parts 
  of 
  No. 
  7 
  coalesce 
  in 
  Nos. 
  8 
  and 
  9 
  and 
  

   part 
  again 
  in 
  No. 
  10, 
  beyond 
  which 
  to 
  the 
  south 
  the 
  upper 
  one, 
  

   once 
  the 
  large 
  one, 
  fails 
  entirely. 
  We 
  are 
  confronted 
  with 
  some 
  

   difficulties 
  in 
  following 
  out 
  the 
  folds 
  in 
  whatever 
  way 
  we 
  may 
  try 
  

   to 
  explain 
  them. 
  We 
  must 
  consider 
  the 
  Miller 
  as 
  an 
  expanded 
  

   prolongation 
  of 
  Old 
  Bed 
  before 
  folding 
  ; 
  that 
  is 
  that 
  the 
  Miller 
  was 
  

   longer 
  north 
  and 
  south, 
  so 
  as 
  to 
  allow 
  for 
  its 
  extended 
  pod 
  in 
  sec- 
  

   tions 
  13-18. 
  Probably 
  the 
  under 
  one 
  of 
  the 
  two 
  pods 
  in 
  No. 
  10 
  

   was 
  connected 
  with 
  Old 
  Bed 
  and 
  that 
  it 
  was 
  doubled 
  over 
  on 
  itself 
  

   as 
  shown 
  in 
  Nos. 
  7 
  and 
  8. 
  It 
  must 
  either 
  have 
  been 
  this 
  or 
  else 
  the 
  

   upper 
  member 
  is 
  the 
  prolongation 
  and 
  the 
  bed 
  was 
  doubled 
  under 
  

   itself 
  to 
  account 
  for 
  Nos. 
  7 
  and 
  8. 
  Or 
  else 
  the 
  Miller 
  is 
  a 
  forking 
  

   pod, 
  from 
  a 
  central 
  thickened 
  portion 
  in 
  Nos. 
  8 
  and 
  9, 
  where 
  the 
  

   two 
  parts 
  coalesce. 
  Any 
  of 
  these 
  three 
  relations 
  is 
  possible, 
  but 
  if 
  

   we 
  favor 
  folding 
  we 
  can 
  not 
  avoid 
  giving 
  great 
  emphasis 
  to 
  the 
  

   viscosity 
  or 
  doughlike 
  consistency 
  of 
  the 
  rocks 
  at 
  the 
  time, 
  since 
  

   in 
  no 
  other 
  way 
  could 
  they 
  possibly 
  have 
  bulged 
  and 
  molded 
  them- 
  

   selves 
  into 
  these 
  forms. 
  So 
  pronounced 
  is 
  this 
  character 
  that 
  one 
  

   can 
  not 
  well 
  help 
  giving 
  serious 
  attention 
  to 
  possible 
  convolutions 
  

   in 
  a 
  molten 
  but 
  ropy 
  mass. 
  Under 
  the 
  latter 
  assumption 
  we 
  need 
  

   infer 
  burial 
  in 
  the 
  earth 
  at 
  a 
  less 
  depth 
  in 
  order 
  to 
  make 
  the 
  

   results 
  possible. 
  

  

  The 
  following 
  analyses 
  illustrate 
  the 
  composition 
  of 
  the 
  ores 
  

   from 
  the 
  " 
  21 
  " 
  pit. 
  No. 
  1 
  was 
  a 
  sample 
  of 
  65 
  carloads 
  and 
  No. 
  2 
  

   of 
  35 
  carloads 
  from 
  the 
  Port 
  Henry 
  Co.
