  Forty-seventh 
  Report 
  on 
  the 
  State 
  Museum. 
  

  

  Ackley 
  on 
  the 
  Conewango, 
  two 
  miles 
  south 
  of 
  the 
  State 
  line. 
  

   East 
  of 
  Fentonville 
  just 
  north 
  of 
  the 
  State 
  lice 
  it 
  is 
  at 
  least 
  

   fifteen 
  feet 
  thick. 
  At 
  Corydon 
  on 
  the 
  Allegany 
  river, 
  at 
  the 
  

   State 
  fine, 
  it 
  is 
  sixteen 
  feet 
  thick 
  and 
  maintains 
  this 
  thickness, 
  

   going 
  north 
  from 
  this 
  point. 
  On 
  Quaker 
  run, 
  Red 
  House 
  creek 
  

   and 
  along 
  the 
  Tuna 
  creek 
  it 
  is 
  about 
  fifteen 
  feet 
  thick 
  as 
  far 
  as 
  I 
  

   have 
  traced 
  it. 
  At 
  a 
  rock 
  city, 
  about 
  three 
  quarters 
  of 
  a 
  miJe 
  

   northeast 
  of 
  Carrollton, 
  it 
  is 
  twelve 
  feet 
  thick, 
  massive 
  and 
  peb- 
  

   bly 
  all 
  through. 
  This 
  is 
  the 
  most 
  northeasterly 
  locality 
  where 
  

   it 
  was 
  seen. 
  On 
  the 
  west 
  side 
  of 
  the 
  Red 
  House 
  creek, 
  H\e 
  and 
  

   a 
  half 
  miles 
  north 
  of 
  the 
  State 
  line 
  (section 
  K), 
  it 
  is 
  twenty 
  feet 
  

   thick. 
  This 
  is 
  at 
  the 
  same 
  latitude 
  as 
  the 
  exposure 
  at 
  Panama, 
  

   where 
  it 
  is 
  sixty-nine 
  feet 
  thick 
  and 
  where 
  it 
  attains 
  its 
  maximum 
  

   thickness. 
  

  

  Pope 
  Hollow 
  Rock. 
  

  

  This 
  rock 
  is 
  well 
  developed 
  throughout 
  the 
  district 
  surveyed. 
  

   It 
  is 
  about 
  twenty 
  feet 
  thick 
  and 
  is 
  a 
  sandstone 
  with 
  flat 
  peb- 
  

   bles, 
  but 
  contains 
  fewer 
  pebbles 
  than 
  the 
  Panama 
  rock. 
  In 
  the 
  

   Bradford 
  oil 
  well 
  it 
  is 
  very 
  distinctly 
  shown, 
  " 
  a 
  sandstone 
  with 
  

   few 
  pebbles." 
  North 
  of 
  this 
  there 
  are 
  numerous 
  exposures 
  in 
  

   the 
  hills 
  bordering 
  the 
  Tuna 
  valley. 
  On 
  Limestone 
  brook 
  

   (section 
  E) 
  it 
  makes 
  vertical 
  cliffs 
  and 
  also 
  near 
  the 
  head 
  

   of 
  Irish 
  brook 
  (section 
  F, 
  Rice 
  brook). 
  It 
  is 
  also 
  indistinctly 
  

   shown 
  on 
  the 
  north 
  face 
  of 
  Bald 
  mountain 
  south 
  of 
  

   Limestone 
  (section 
  C). 
  At 
  "rock 
  city," 
  northeast 
  of 
  Car- 
  

   rollton, 
  it 
  is 
  seen 
  lying 
  above 
  the 
  Panama 
  rock. 
  East 
  

   of 
  Irvine 
  Mills 
  a 
  similar 
  rock 
  is 
  seen, 
  but 
  the 
  elevation 
  

   seems 
  to 
  be 
  too 
  great, 
  2110 
  feet. 
  This 
  is 
  only 
  twenty- 
  

   one 
  feet 
  lower 
  than 
  the 
  exposure 
  northeast 
  of 
  Carrollton, 
  two 
  

   and 
  three-quarter 
  miles 
  farther 
  north. 
  I 
  think 
  this 
  is 
  the 
  nine- 
  

   teen 
  feet 
  of 
  sandstone 
  which 
  lies 
  above 
  the 
  Pope 
  Hollow 
  rock 
  at 
  

   "Warren, 
  Pennsylvania, 
  of 
  which 
  I 
  have 
  seen 
  indications 
  through 
  

   Chautauqua 
  and 
  Cattaraugus 
  counties, 
  New 
  York. 
  This 
  rock 
  is 
  

   again 
  seen 
  at 
  the 
  head 
  of 
  Bailett's 
  brook 
  (section 
  G), 
  one 
  and 
  

   three-quarter 
  miles 
  south 
  of 
  Irvine 
  Mills. 
  I 
  did 
  not 
  find 
  an 
  expo- 
  

   sure 
  of 
  the 
  Pope 
  Hollow 
  rock 
  on 
  the 
  Red 
  House 
  creek 
  or 
  Quaker 
  

   run, 
  but 
  have 
  no 
  doubt 
  that 
  it 
  is 
  there, 
  and 
  that 
  future 
  search 
  

   will 
  reveal 
  it.
