  * 
  To 
  return 
  to 
  the 
  Chenango 
  .valley 
  and 
  its 
  Oneonta 
  beds 
  ; 
  it 
  has 
  

   been 
  shown 
  that 
  these 
  red 
  and 
  green 
  shales 
  and 
  sandstones 
  over- 
  

   lie 
  the 
  barren 
  sandstones 
  capping 
  the 
  fossiliferous 
  Ithaca 
  beds. 
  

   Mention 
  has 
  been 
  made 
  of 
  the 
  extensive 
  development 
  in 
  these 
  

   Oneonta 
  beds 
  of 
  the 
  peculiar 
  layers 
  of 
  red 
  and 
  green 
  concretion- 
  

   ary 
  masses, 
  the 
  typical 
  " 
  Kranienzel," 
  which 
  also 
  occurs 
  on 
  a 
  

   much 
  smaller 
  scale 
  in 
  the 
  Naples 
  beds 
  of 
  Ontario 
  county. 
  This 
  

   concurrence 
  of 
  a 
  lithological 
  character 
  in 
  the 
  upper 
  Devonian, 
  

   which 
  is 
  so 
  unusual 
  in 
  this 
  country, 
  and 
  so 
  widespread 
  and 
  char- 
  

   acteristic 
  at 
  corresponding 
  horizons 
  throughout 
  Germany, 
  espec- 
  

   ially 
  in 
  the 
  Eifel 
  and 
  Westphalia, 
  can 
  not 
  be 
  a 
  mere 
  incident. 
  

   The 
  evidence 
  before 
  us 
  seems 
  to 
  me 
  to 
  indicate 
  that 
  these 
  Oneonta 
  

   beds 
  (including 
  the 
  barren 
  gray 
  sands 
  and 
  flags 
  lying 
  beneath 
  the 
  

   red 
  and 
  green 
  shales 
  and 
  sands) 
  are 
  the 
  eastern 
  representative 
  of 
  

   the 
  upper 
  sandstones 
  and 
  flags 
  originally 
  designated 
  by 
  Prof. 
  

   Hall 
  as 
  the 
  "Portage 
  sandstones," 
  and 
  are 
  hence 
  the 
  sedimentary 
  

   equivalent 
  of 
  the 
  typical 
  Portage. 
  The 
  sections 
  in 
  the 
  vicinity 
  

   of 
  Greene 
  show 
  very 
  clearly 
  that 
  these 
  beds 
  are 
  overlaid 
  by 
  a 
  

   typical 
  and 
  highly-developed 
  Chemung 
  fauna. 
  

  

  Kespectfully 
  yours.

  M.
