  Forty-seventh 
  Report

  the 
  State 
  Museum. 
  

  

  three 
  and 
  one-half 
  miles 
  northwest 
  of 
  Limestone 
  (section 
  F.) 
  

   Here 
  its 
  upper 
  surface 
  is 
  tAventy-five 
  feet 
  above 
  the 
  Pope 
  Hollow 
  

   rock, 
  but 
  the 
  entire 
  thickness 
  could 
  not 
  be 
  ascertained. 
  It 
  was 
  

   again 
  seen 
  on 
  the 
  east 
  side 
  of 
  Bed 
  House 
  creek 
  (section 
  I). 
  It 
  

   evidently 
  lies 
  just 
  above 
  the 
  Pope 
  Hollow 
  creek. 
  "W 
  hile 
  in 
  the 
  

   field 
  there 
  seemed 
  to 
  be 
  so 
  many 
  horizons 
  of 
  red 
  rock 
  that 
  i 
  did 
  

   not 
  appreciate 
  their 
  importance 
  but 
  simply 
  took 
  the 
  elevations. 
  

   Not 
  until 
  they 
  were 
  placed 
  upon 
  the 
  diagram 
  was 
  I 
  certain 
  that 
  

   they 
  were 
  extensions 
  of 
  the 
  same 
  band. 
  

  

  There 
  is 
  a 
  lower 
  red 
  rock 
  shown 
  in 
  the 
  Bradford 
  oil 
  well, 
  also 
  

   on 
  Buchanan 
  hill 
  (section 
  B), 
  Bald 
  mountain 
  (section 
  C), 
  and 
  on 
  

   Nichol's 
  run 
  (section 
  D-l). 
  About 
  550 
  feet 
  below 
  the 
  Pope 
  

   Hollow 
  rock 
  in 
  the 
  Bradford 
  oil 
  well 
  is 
  another 
  red 
  horizon. 
  On 
  

   Quaker 
  run 
  (section 
  S) 
  a 
  red 
  rock 
  was 
  seen 
  underlaid 
  by 
  flags 
  ; 
  

   also 
  just 
  south 
  of 
  Carrollton 
  a 
  red 
  rock 
  is 
  visible 
  (section 
  0). 
  

   Faint 
  traces 
  of 
  a 
  red 
  shale 
  were 
  seen 
  north 
  of 
  Salamanca 
  at 
  the 
  

   water-works. 
  These 
  may 
  possibly 
  be 
  of 
  the 
  same 
  horizon, 
  but 
  it 
  

   needs 
  further 
  study 
  to 
  confirm 
  this 
  point. 
  I 
  have 
  placed 
  upon 
  

   the 
  diagram 
  the 
  section 
  (M) 
  on 
  Gray's 
  run, 
  southeast 
  of 
  Steam- 
  

   burgh 
  and 
  west 
  of 
  the 
  Allegany 
  river 
  where 
  the 
  Elko 
  mine 
  red 
  

   rock 
  and 
  Panama 
  conglomerate 
  outcrop, 
  to 
  show 
  its 
  close 
  agree- 
  

   ment 
  with 
  this 
  interpretation 
  of 
  the 
  geological 
  structure. 
  

  

  Mauch 
  Chunk 
  Red 
  Shale. 
  

  

  The 
  Second 
  Geological 
  Survey 
  of 
  Pennsylvania, 
  in 
  its 
  report 
  

   upon 
  McKean 
  county, 
  says 
  that 
  the 
  Mauch 
  Chunk 
  red 
  shale 
  was 
  

   not 
  found 
  except 
  in 
  the 
  southeastern 
  portion 
  of 
  that 
  

   county. 
  

  

  In 
  my 
  investigation 
  in 
  Cattaraugus 
  county 
  no 
  red 
  rock 
  lying 
  

   beneath 
  the 
  Clean 
  conglomerate 
  was 
  seen 
  except 
  at 
  one 
  locality, 
  

   viz. 
  : 
  at 
  the 
  head 
  of 
  Irish 
  rua, 
  four 
  miles 
  northeast 
  of 
  Limestone 
  

   station. 
  Here 
  a 
  very 
  red 
  thin-bedded 
  micaceous 
  layer 
  is 
  seen 
  

   capping 
  the 
  hill, 
  twenty-five 
  feet 
  below 
  the 
  base 
  of 
  the 
  Olean 
  

   conglomerate 
  which 
  forms 
  a 
  rock 
  city 
  150 
  yards 
  away. 
  In 
  

   consequence 
  of 
  its 
  position 
  the 
  thickness 
  could 
  not 
  be 
  ascertained, 
  

   but 
  I 
  should 
  estimate 
  it 
  at 
  from 
  five 
  to 
  ten 
  feet. 
  It 
  appears 
  to 
  

   contain 
  obscure 
  .vegetable 
  remains 
  ; 
  one-half 
  mile 
  west 
  of 
  this 
  I 
  

   found 
  a 
  loose 
  block 
  that 
  resembles 
  it 
  closely, 
  but 
  fifty 
  feet 
  lower,
