  A 
  few 
  miles 
  northwest 
  of 
  Titusville 
  is 
  the 
  village 
  of 
  Hyde- 
  

   town, 
  through 
  which 
  flows 
  Thompson's 
  Run. 
  A 
  branch 
  of 
  

   this 
  run 
  just 
  above 
  the 
  village 
  is 
  called 
  Hyde 
  Run. 
  Along 
  

   this 
  creek 
  the 
  section 
  was 
  seen.

  In 
  the 
  section 
  above 
  it 
  is 
  more 
  than 
  likely 
  that 
  the 
  Meadville 
  

   formation 
  begins 
  with 
  No.

  In 
  that 
  case 
  the 
  Shenango 
  

   sandstone 
  is 
  concealed 
  in 
  the 
  33-foot 
  interval 
  (No.

  The 
  

   general 
  topography 
  of 
  the 
  stream 
  also 
  seems 
  to 
  bear 
  this 
  out. 
  

   The 
  part 
  of 
  the 
  section 
  including 
  No.

  to

  was 
  obtained 
  by 
  

   following 
  the

  leading

  Thompson's

  one-half
