  immense

  of 
  small

  The 
  base 
  of 
  this 
  cut 
  is 
  approximately 
  199 
  feet 
  above 
  the 
  red 
  

   sandstone 
  of 
  67B 
  2 
  , 
  or 
  137 
  feet 
  higher 
  than 
  the 
  bottom 
  of 
  the 
  rail- 
  

   road 
  cut 
  at 
  67B 
  4 
  , 
  two 
  miles 
  farther 
  northwest, 
  and 
  is, 
  conse- 
  

   quently, 
  at 
  least 
  that 
  much 
  higher 
  stratigraphically 
  in 
  the 
  Che- 
  

   mung 
  formation. 
  

  

  The 
  high 
  hill 
  to 
  the 
  west 
  of 
  Carrs 
  creek, 
  south 
  of 
  May 
  wood, 
  

   affords 
  an 
  opportunity 
  to 
  measure 
  the 
  thickness 
  of 
  the 
  Chemung 
  

   formation. 
  A 
  section 
  has 
  been 
  constructed 
  showing 
  the 
  rocks 
  

   from 
  the 
  level 
  of 
  Carrs 
  creek 
  at 
  67B 
  1 
  to 
  the 
  top 
  of 
  the 
  high 
  hill 
  

   near 
  the 
  Sidney-Masonville 
  township 
  line 
  south 
  of 
  Maywood. 
  The 
  

   course 
  of 
  this 
  section 
  from 
  Maywood 
  south 
  is 
  up 
  the 
  valley 
  of 
  

   Carrs 
  creek 
  to 
  the 
  first 
  road 
  turning 
  west 
  and 
  then 
  over 
  the 
  hill 
  

   to 
  East 
  Masonville. 
  Unfortunately 
  in 
  measuring 
  the 
  section 
  that 
  

   route 
  was 
  not 
  followed 
  so 
  that 
  the 
  covered 
  zone 
  called 
  A 
  3 
  and 
  

   estimated 
  as 
  209 
  feet 
  in 
  thickness 
  may 
  vary 
  to 
  quite 
  an 
  extent 
  

   from 
  that 
  approximation. 
  On 
  this 
  hill 
  the 
  grayish 
  to 
  olive 
  sand- 
  

   stones 
  were 
  noted 
  at 
  the 
  horizon 
  A 
  4 
  which 
  is 
  estimated 
  as 
  475 
  

   feet 
  above 
  the 
  level 
  of 
  Carrs 
  creek 
  at 
  B 
  1 
  , 
  and 
  they 
  continue 
  to 
  

   at 
  least 
  an 
  altitude 
  of 
  615 
  feet 
  the 
  last 
  80 
  feet 
  of 
  which 
  are 
  com- 
  

   posed 
  largely 
  of 
  rather 
  coarse 
  grained 
  grayish 
  sandstone 
  and 
  

   some 
  olive 
  shale. 
  This 
  zone 
  is 
  apparently 
  in 
  the 
  Cheniung 
  al- 
  

   though 
  a 
  hasty 
  search 
  was 
  not 
  rewarded 
  with 
  fossils.

  formation, 
  the

  of 
  

   the

  this 
  section 
  would 
  then 
  be
