  Oneonta 
  

  

  Oneonta 
  is 
  one 
  of 
  the* 
  southern 
  townships 
  of 
  Otsego 
  co., 
  to 
  

   the 
  north 
  of 
  which 
  are 
  the 
  townships 
  of 
  Milford 
  and 
  Laurens, 
  the 
  

   geology 
  of 
  which 
  was 
  described 
  in 
  part 
  1 
  of 
  this 
  report; 
  to 
  the 
  

   west 
  is 
  Otego 
  township 
  and 
  on 
  the 
  south 
  are 
  the 
  townships 
  of 
  

   Franklin 
  and 
  Davenport 
  in 
  Delaware 
  co. 
  The 
  Susquehanna 
  

   river 
  crosses 
  the 
  southern 
  central 
  part 
  of 
  the 
  township 
  from 
  nearly 
  

   east 
  to 
  west 
  and 
  is 
  lined 
  by 
  steep 
  hills 
  on 
  both 
  the 
  northern 
  and 
  

   southern 
  sides. 
  The 
  northern 
  line 
  is 
  broken 
  by 
  the 
  Emmons, 
  

   Oneonta 
  and 
  Otego 
  creeks; 
  but 
  the 
  steep 
  line 
  to 
  the 
  south 
  of 
  the 
  

   Susquehanna 
  and 
  Charlotte 
  rivers 
  is 
  unbroken 
  save 
  by 
  small 
  

   brooks. 
  

  

  The 
  Ithaca 
  formation. 
  In 
  the 
  first 
  part 
  of 
  this 
  report 
  the 
  bluish 
  

   shales 
  containing 
  a 
  few 
  fossils 
  which 
  occur 
  along 
  the 
  river 
  road 
  

   about 
  one 
  half 
  mile 
  north 
  of 
  Colliersville 
  in 
  the 
  southern 
  part 
  of 
  

   Milford 
  township 
  were 
  described. 
  These 
  rocks 
  were 
  referred, 
  with 
  

   some 
  hesitation, 
  to 
  the 
  Sherburne 
  formation 
  and 
  probably 
  belong 
  

   near 
  its 
  top. 
  On 
  the 
  high 
  hill 
  to 
  the 
  east 
  of 
  the 
  river 
  and 
  northeast 
  

   of 
  South 
  Milford 
  are 
  exposures 
  of 
  the 
  Sherburne 
  sandstones.^

  The 
  next 
  locality 
  studied 
  was 
  a 
  glen, 
  known 
  as 
  

   Collier's 
  gulf, 
  less 
  than 
  one 
  mile 
  southwest 
  of 
  Colliersville 
  in 
  the 
  

   southern 
  part 
  of 
  Milford 
  township. 
  From 
  the 
  railroad 
  level 
  to 
  

   the 
  base 
  of 
  the 
  lowest 
  rocks 
  exposed 
  in 
  the 
  brook 
  is 
  about 
  45 
  feet, 
  

   succeeding 
  which 
  are 
  60 
  feet 
  of 
  shales 
  and 
  thin 
  bluish 
  sandstones 
  

   below 
  the 
  highway. 
  The 
  rocks 
  contain 
  scarcely 
  any 
  fossils 
  and 
  

   are 
  referred 
  to 
  the 
  Sherburne 
  formation.

  A

  . 
  In 
  the 
  glen 
  above 
  the 
  highway 
  bridge 
  for 
  some 
  40 
  feet 
  

   the 
  rocks 
  are 
  shales 
  in 
  which 
  Chonetes 
  and 
  Spirifer 
  mucronatus 
  

   (Con.) 
  Bill, 
  are 
  common. 
  These 
  shales 
  contain 
  the 
  lower 
  fauna 
  of 
  

   the 
  Ithaca 
  group 
  as 
  it 
  occurs 
  in 
  the 
  Chenango 
  and 
  Unadilla 
  

   valleys 
  and 
  this 
  zone 
  is 
  referred 
  to 
  the 
  base 
  of 
  that 
  formation. 
  

   The 
  complete 
  fauna 
  is:
