  Forty-seventh 
  Report 
  on 
  the 
  State 
  Museum, 
  

  

  Just 
  as 
  I 
  was 
  starting 
  into 
  the 
  field 
  there 
  appeared 
  in 
  the 
  

   American 
  Journal 
  of 
  Science 
  for 
  September 
  an 
  important 
  paper 
  

   by 
  Prof. 
  C. 
  S. 
  Prosser, 
  on 
  the 
  very 
  section 
  that 
  I 
  was 
  then 
  to 
  

   study, 
  entitled 
  "The 
  Upper 
  Hamilton 
  and 
  Portage 
  Stages 
  of 
  

   Central 
  and 
  Eastern 
  New 
  York." 
  Much 
  to 
  my 
  regret 
  I 
  knew 
  

   nothing 
  of 
  the 
  existence 
  of 
  this 
  paper 
  until 
  after 
  my 
  return; 
  

  

  could 
  it 
  have 
  been 
  in 
  my 
  hands 
  during 
  the 
  explorations 
  in 
  the 
  

   Chenango 
  valley 
  it 
  would 
  have 
  been 
  of 
  great 
  service. 
  This 
  

   paper 
  puts 
  forth 
  the 
  view, 
  supported 
  by 
  a 
  well-constructed 
  argu- 
  

   ment, 
  that 
  the 
  fauna 
  lying 
  beneath 
  the 
  Oneonta 
  shales 
  and 
  sand- 
  

   stones 
  is 
  a 
  Hamilton 
  fauna 
  only 
  in 
  the 
  sense 
  that 
  it 
  contains 
  a 
  

   considerable 
  number 
  of 
  Hamilton 
  species, 
  whose 
  typical 
  expres- 
  

   sion 
  is 
  often 
  more 
  or 
  less 
  modified 
  ; 
  that 
  it 
  lies 
  above 
  the 
  horizon 
  

   of 
  the 
  Tully 
  limestone 
  and 
  Genesee 
  shales, 
  as 
  indicated 
  by 
  their
