  and 
  hence 
  its 
  absence 
  leaves 
  a 
  certain 
  element 
  of 
  doubt 
  as 
  to 
  the 
  

   position 
  of 
  the 
  mesastriaMs-isLunsL, 
  though 
  there 
  is 
  no 
  evidence 
  

   either 
  in 
  the 
  physical 
  structure 
  of 
  the 
  valley 
  or 
  in 
  the 
  observed 
  

   succession 
  of 
  the 
  rocks 
  at 
  Norwich 
  for 
  assuming 
  that 
  these 
  Gen? 
  

   esee 
  shales 
  or 
  their 
  horizon 
  is 
  to 
  be 
  found 
  in 
  the 
  section 
  some- 
  

   where 
  between 
  its 
  base 
  and 
  the 
  appearance 
  of 
  the 
  red 
  shales 
  and 
  

   sandstones. 
  In 
  the 
  western 
  tovns 
  of 
  Chenango 
  county 
  and 
  in 
  

   Cincirmatus 
  the 
  evidence 
  on 
  this 
  point, 
  is 
  more 
  direct. 
  In 
  Cin- 
  

   cinnatus, 
  Pitcher 
  and 
  Otselic 
  the 
  mesastrialis-fELxmai, 
  is 
  well 
  

   developed 
  and 
  of 
  quite 
  the 
  same 
  character 
  as 
  that 
  of 
  the 
  lower 
  

   beds 
  at 
  Norwich. 
  But 
  these 
  beds 
  clearly 
  and 
  unmistakably 
  lie 
  

   above 
  the 
  Genesee 
  shades, 
  which 
  were 
  observed 
  by 
  me 
  in 
  several 
  

   places, 
  en 
  passant 
  just 
  north 
  of 
  the 
  village 
  of 
  Linckiaen 
  on 
  the 
  

   road 
  to 
  De 
  Euyter. 
  On 
  Prof. 
  S. 
  G. 
  Williams' 
  map 
  showing 
  the 
  

   extent 
  of 
  the 
  Tully 
  limestone 
  in 
  New 
  York 
  (Sixth 
  Annual 
  

   Eeport 
  State 
  Geologist, 
  1887) 
  this 
  formation 
  is 
  represented 
  as 
  

   passing 
  close 
  to, 
  slightly 
  to 
  the 
  north 
  and 
  east 
  of 
  the 
  village 
  of 
  

   De 
  Euyter. 
  There 
  is 
  hence 
  positively 
  no 
  question 
  that 
  the 
  Cin- 
  

   cinnatus 
  and 
  Pitcher 
  beds 
  containing 
  the 
  mesastrialis-i&xm& 
  lie 
  

   above 
  and 
  probably 
  immediately 
  above 
  the 
  Genesee 
  shales. 
  

   And 
  with 
  as 
  little 
  hesitation 
  we 
  may' 
  infer 
  that 
  the 
  Norwich 
  

   representation 
  of 
  the 
  same 
  fauna 
  lies 
  above 
  the 
  horizon 
  of 
  the 
  

   Genesee 
  shales. 
  Throughout 
  the 
  western 
  part 
  of 
  the 
  region 
  

   here 
  under 
  consideration 
  the 
  upper 
  portion 
  of 
  the 
  serie- 
  was 
  not 
  

   closely 
  studied. 
  It 
  was, 
  however, 
  observed 
  that 
  in 
  the 
  section 
  

   between 
  Pitcher 
  Springs 
  and 
  the 
  Otselic 
  valle}^, 
  sandstones 
  and 
  

   thick 
  flags 
  gradually 
  become 
  predominant 
  in 
  the 
  upper 
  layers; 
  

   this 
  is 
  very 
  clearly 
  shown 
  in 
  the 
  Chenango 
  valley 
  sections, 
  

   where 
  the 
  increase 
  in 
  the 
  arenaceous 
  character 
  of 
  the 
  sediment 
  

   is 
  accompanied 
  by 
  a 
  diminution 
  of 
  organic 
  life. 
  

  

  All 
  this, 
  however, 
  is 
  no 
  new 
  determination. 
  Yanuxem 
  in 
  his 
  

   special 
  chapters 
  (Report 
  Third 
  Geological 
  District, 
  1842) 
  on 
  

   Chenango 
  and 
  Cortland 
  counties 
  referred 
  these 
  rocks 
  to 
  his 
  

   Ithaca 
  group, 
  without 
  any 
  detailed 
  observations 
  in 
  regard 
  to 
  

   superposition 
  or 
  the 
  character 
  of 
  the 
  successive 
  faunas. 
  As 
  the 
  

   Hamilton 
  fauna 
  was 
  elaborated 
  and 
  its 
  component 
  species 
  

   became 
  fairly 
  well 
  known, 
  it 
  is 
  quite 
  natural 
  that 
  the 
  rocks 
  bear- 
  

   ing 
  these 
  supra-Hamilton 
  faunas 
  in 
  the 
  Chenango 
  valley 
  and 
  

   Otsego 
  county 
  should 
  have 
  been, 
  in 
  a 
  desultory 
  fashion, 
  referred
