  then 
  15 
  feet 
  of 
  thin 
  bluish 
  sandstones 
  occur. 
  Some 
  of 
  the 
  layers 
  

   are 
  very 
  fossiliferous 
  and 
  being 
  strongly 
  calcareous 
  form 
  a 
  sort 
  

   of 
  flrestone. 
  The 
  number 
  of 
  species 
  is 
  small, 
  Spirifer 
  mssastriaMs 
  

   Hall 
  being 
  the 
  most 
  abundant 
  forms 
  a 
  large 
  part 
  of 
  the 
  thin 
  

   layers 
  of 
  firestone. 
  This 
  zone 
  very 
  strongly 
  resembles 
  some 
  of 
  

   the 
  calcareous 
  layers 
  near 
  the 
  middle 
  of 
  the 
  Ithaca 
  formation 
  at 
  

   Ithaca, 
  New 
  York. 
  The 
  top 
  of 
  this 
  zone 
  225 
  feet 
  above 
  the 
  level 
  

   of 
  the 
  railroad 
  is 
  at 
  the 
  head 
  of 
  the 
  glen, 
  above 
  which 
  the 
  rocks 
  

   are 
  mostly 
  concealed 
  by 
  the 
  soil 
  and 
  drift. 
  The 
  following 
  species 
  

   were 
  collected 
  in 
  a 
  few 
  moments:

  In 
  the 
  search 
  for 
  fossils 
  in 
  the 
  zones 
  of 
  this 
  section 
  but 
  little 
  

   time 
  was 
  spent 
  and 
  more 
  exhaustive 
  collecting 
  would 
  undoubt- 
  

   edly 
  increase 
  the 
  number 
  of 
  species 
  for 
  each 
  zone. 
  It 
  is 
  con- 
  

   sidered, 
  however, 
  that 
  these 
  lists 
  when 
  taken 
  into 
  consideration 
  

   with 
  the 
  stratigraphy 
  of 
  the 
  southern 
  part 
  of 
  Milford 
  township 
  

   show 
  conclusively 
  that 
  at 
  least 
  the 
  upper 
  80 
  feet 
  of 
  the 
  section 
  

   belong 
  in 
  the 
  Ithaca 
  formation, 
  while 
  the 
  writer 
  would 
  refer 
  the 
  

   upper 
  120 
  feet 
  to 
  that 
  formation 
  and 
  leave 
  the 
  lower 
  105 
  feet 
  in 
  

   the 
  Sherburne 
  formation.

  Three 
  miles 
  east 
  of 
  Oneonta 
  in 
  the 
  eastern 
  part 
  of 
  

   Oneonta 
  township 
  is 
  the 
  " 
  old 
  Emmons 
  farm 
  " 
  now 
  owned 
  by 
  M. 
  

   L. 
  Swartz. 
  At 
  this 
  locality 
  is 
  a 
  steep 
  hill 
  and 
  the 
  base 
  of 
  the 
  

   section 
  is 
  at 
  railroad 
  level 
  about 
  one 
  half 
  mile 
  above 
  Emmons 
  

   station. 
  ,The 
  highway 
  is 
  some 
  55 
  feet 
  above 
  the 
  railroad 
  level 
  

   and 
  then 
  for 
  265 
  feet 
  the 
  rocks 
  forming 
  the 
  steep 
  part 
  of 
  the 
  hill 
  

   are 
  largely 
  covered 
  and 
  only 
  an 
  occasional 
  outcrop 
  of 
  shale 
  is 
  

   visible. 
  Then 
  ledges 
  occur 
  forming 
  a 
  conspicuous 
  terrace 
  along 
  

   the 
  side 
  of 
  the 
  hill 
  which 
  seems 
  to 
  be 
  its 
  brow 
  when 
  viewed 
  from 
  

   the 
  highway. 
  One 
  layer 
  is 
  hard 
  and 
  somewhat 
  calcareous 
  con- 
  

   taining 
  some 
  pebbles 
  and 
  plenty 
  of 
  fossils 
  specially 
  Camarotoechia. 
  

   These 
  rocks 
  contain 
  the 
  fauna 
  of 
  the 
  Ithaca 
  formation, 
  as 
  will 
  be
