  -four 
  inches 
  in 
  thickness 
  ;

  gray 
  shales,

  The 
  shales 
  on 
  this 
  section 
  are 
  soft, 
  clayey 
  and 
  greenish. 
  Fossils 
  

   are 
  exceedingly 
  and

  throughout. 
  One 
  of 
  the 
  

   flagstones 
  furnished 
  a 
  thin 
  layer 
  containing

  Station 
  D. 
  An 
  extensive 
  quarry 
  on 
  the 
  property 
  of 
  Oscar 
  Hale, 
  

   at 
  top 
  of 
  the 
  hill 
  further 
  west 
  on 
  the 
  same 
  road, 
  and 
  one 
  and 
  one- 
  

   half 
  miles 
  west 
  of 
  Norwich 
  post-office. 
  Before 
  considering 
  this 
  

   exposure 
  in 
  detail, 
  a 
  road 
  section 
  may 
  be 
  given, 
  which, 
  though 
  

   studied 
  at 
  a 
  disadvantage 
  on 
  account 
  of 
  scanty 
  exposures, 
  serves 
  

   to 
  continue 
  the 
  section 
  given 
  at 
  C 
  almost 
  to 
  the 
  base 
  of 
  section 
  D. 
  

   The 
  Preston 
  road 
  rapidly 
  rises 
  from 
  the 
  base 
  of 
  the 
  hill 
  below 
  C 
  

   toward 
  D, 
  and 
  the 
  greenish 
  flags 
  (3) 
  are 
  cut 
  by 
  the 
  road 
  work, 
  

   above 
  them 
  lying 
  the 
  greenish 
  shales 
  (4) 
  of 
  0. 
  Above 
  these 
  are 
  

   compact 
  green 
  flags 
  Ml 
  of 
  shale 
  pebbles 
  ano 
  lignites, 
  and 
  

   weathering 
  very 
  rusty 
  along 
  certain 
  lines. 
  These 
  are 
  about 
  seven 
  

   feet 
  in 
  thickness. 
  Over 
  these 
  are 
  two 
  feet 
  six 
  inches 
  of 
  greenish 
  

   flaggy 
  sandstone 
  with 
  black 
  organic 
  vertical 
  markings, 
  above 
  

   which 
  are 
  two 
  feet 
  six 
  inches 
  of 
  brownish 
  yellow 
  sandstone. 
  

   At 
  the 
  top 
  of 
  this 
  roadside 
  section 
  are 
  about 
  three 
  feet 
  of 
  soft 
  red 
  

   and 
  green 
  sandy 
  shales 
  with 
  minute 
  fish 
  bones 
  and 
  entomostracal 
  

   This 
  top 
  layer 
  can 
  not 
  be 
  far 
  from 
  fifteen 
  feet 
  from 
  the 
  base 
  of 
  

   the 
  section 
  at 
  D. 
  At 
  D 
  the 
  following 
  exposure 
  is 
  afforded, 
  from 
  

   the 
  bottom 
  : 
  

  

  (1) 
  Compact 
  light 
  gray 
  -green 
  sandstone, 
  breaking 
  out 
  at 
  the 
  

   base 
  into 
  flags 
  six 
  to 
  ten 
  inches 
  thick 
  ; 
  above 
  these 
  the 
  sandstone
