  The 
  comparison 
  of 
  the 
  section 
  north 
  of 
  Sidney 
  with 
  that 
  of 
  the 
  

   Otsdawa 
  north 
  of 
  Otego 
  furnishes 
  a 
  means 
  of 
  estimating 
  the 
  

   thickness 
  of 
  theOneonta 
  formation. 
  The 
  distance 
  between 
  the 
  two 
  

   sections 
  is 
  12^ 
  miles; 
  the 
  Sidney 
  station 
  is 
  64 
  feet 
  lower 
  than 
  the 
  

   Otego 
  while 
  the 
  base 
  of 
  the 
  Oneonta 
  formation 
  on 
  the 
  Otsdawa 
  

   creek 
  is 
  60 
  feet 
  above 
  the 
  railroad 
  level. 
  If 
  we 
  assume 
  that 
  the 
  

   dip 
  remains 
  the 
  same 
  between 
  Otego 
  and 
  Sidney 
  as 
  between
