  easternmost 
  outcrops 
  near 
  the 
  village 
  of 
  Smyrna 
  in 
  the 
  upper 
  

   part 
  of 
  the 
  valley, 
  and 
  is 
  hence 
  representative 
  of 
  the 
  Portage 
  

   group. 
  Inferentially 
  this 
  argument 
  ascribes 
  to 
  the 
  Oneonta 
  

   deposits 
  a 
  supra-Portage 
  or 
  Chemung 
  equivalence. 
  I 
  may 
  

   briefly 
  refer 
  again 
  to 
  Prof. 
  Prosser's 
  observations. 
  

  

  The 
  plan 
  of 
  my 
  field 
  work 
  was 
  to 
  follow 
  meridional 
  sections 
  

   westward 
  from 
  the 
  Chenango 
  river, 
  through 
  Chenango 
  and 
  Cort- 
  

   land 
  counties 
  ; 
  the 
  observations 
  made, 
  however, 
  pertain 
  almost 
  

   wholly 
  to 
  Chenango 
  county. 
  In 
  presenting 
  these 
  traverses 
  I 
  

   have 
  not 
  followed 
  the 
  order 
  in 
  which 
  they 
  were 
  made, 
  but 
  have 
  

   arranged 
  them 
  from 
  north 
  to 
  south 
  along 
  the 
  Chenango 
  valley 
  

   with 
  westward 
  departures. 
  

  

  Station 
  A. 
  One 
  and 
  one-half 
  miles 
  south 
  of 
  Norwich 
  on 
  the 
  val- 
  

   ley 
  road 
  ; 
  exposure 
  along 
  the 
  roadside 
  on 
  the 
  property 
  of 
  William 
  

   Breed 
  ; 
  about 
  fourteen 
  feet 
  thick 
  where 
  opened. 
  At 
  the 
  base 
  of 
  

   this 
  exposure 
  are 
  three 
  feet 
  of 
  a 
  sof 
  tish 
  gray 
  sandstone 
  overlaid 
  for 
  

   the 
  entire 
  height 
  of 
  the 
  section 
  by 
  shaly 
  sandstones 
  and 
  soft 
  

   shales.

  of 
  the 
  softer
