  Top. 
  By 
  combining 
  these 
  two 
  sections, 
  which 
  are 
  only 
  one 
  half 
  

   mile 
  apart, 
  we 
  can 
  get 
  a 
  nearly 
  continuous 
  exposure 
  of 
  800 
  feet. 
  

  

  The 
  section 
  is 
  as 
  follows: 
  

  

  490 
  feet 
  covered. 
  This 
  represents 
  the 
  small 
  hill 
  between 
  the 
  

   river 
  road 
  and 
  the 
  Meredith 
  road, 
  which 
  is 
  partly 
  of 
  glacial 
  

   origin 
  and 
  in 
  which 
  the 
  rocks 
  are 
  -entirely 
  covered 
  with 
  sand, 
  

   gravel. 
  and 
  soil. 
  

  

  16 
  feet 
  of 
  red 
  shales 
  and 
  gray 
  sandstone 
  in 
  Fish's 
  new 
  quarry. 
  

   In 
  the 
  red 
  shales 
  in 
  the 
  lower 
  part 
  of 
  the 
  quarry 
  are 
  found 
  

   numerous 
  sun 
  cracks 
  and 
  some 
  fucoidal 
  markings. 
  On 
  one 
  speci- 
  

   men 
  is 
  a 
  part 
  of 
  a 
  small 
  Lamellibranch 
  'shell, 
  but 
  it 
  is 
  too 
  poorly 
  

   preserved 
  to 
  admit 
  of 
  identification. 
  It 
  is 
  a 
  shell 
  about 
  one 
  

   fourth 
  inch 
  in 
  diameter 
  shaped 
  somewhat 
  like 
  a 
  NuctiJa, 
  and 
  the 
  

   surface 
  is 
  ornamented 
  with 
  several 
  quite 
  strongly 
  marked, 
  con- 
  

   centric 
  lines. 
  Its 
  position 
  in 
  the 
  bright 
  red 
  Oneonta 
  shales 
  so 
  

   far 
  below 
  the 
  base 
  of 
  the 
  Chemung 
  gives 
  it 
  a 
  peculiar 
  interest; 
  

   and 
  we 
  can 
  only 
  hope 
  that 
  further 
  search 
  in 
  the 
  same 
  region 
  

   may 
  furnish 
  more 
  specimens 
  from 
  which 
  the 
  species 
  may 
  be 
  

   identified. 
  The 
  gray 
  sandstone 
  for 
  which 
  the 
  quarry 
  is 
  worked 
  

   and 
  which 
  is 
  used 
  both 
  for 
  flagging 
  and 
  for 
  building 
  stone, 
  con- 
  

   tains 
  large 
  numbers 
  of 
  fragments 
  of 
  plant 
  stems. 
  In 
  some 
  of 
  

   the 
  layers 
  the 
  surface 
  is 
  almost 
  entirely 
  covered 
  with 
  these 
  frag- 
  

   ments, 
  varying 
  in 
  length 
  from 
  one 
  inch 
  to 
  one 
  foot 
  and 
  in 
  width 
  

   from 
  one 
  line 
  to 
  several 
  inches. 
  Other 
  layers 
  have 
  the 
  surface 
  

   curiously 
  mottled 
  with 
  large, 
  light 
  gray, 
  clay 
  pebbles. 
  

  

  14 
  feet, 
  covered. 
  

  

  18 
  feet, 
  heavy 
  gray 
  sandstone 
  in 
  the 
  old 
  quarry 
  which 
  is 
  now 
  

   abandoned. 
  Here 
  the, 
  sandstone 
  is 
  more 
  massive 
  than 
  in 
  the 
  

   other 
  quarry, 
  and 
  the 
  plant 
  fragments 
  are 
  more 
  numerous 
  and 
  

   better 
  preserved. 
  

  

  20 
  feet, 
  covered. 
  

  

  Eight 
  feet 
  thin 
  bedded, 
  coarse 
  grained, 
  gray 
  sandstone. 
  

  

  15 
  feet, 
  covered. 
  . 
  

  

  12 
  feet, 
  red 
  sandstone 
  showing 
  worm 
  trails 
  and 
  fucoid 
  mark- 
  

   ings. 
  

  

  18 
  feet, 
  covered. 
  

  

  10 
  feet, 
  gray 
  sandstone. 
  One 
  layer 
  of 
  this 
  sandstone 
  shows 
  

   some 
  very 
  curious 
  markings 
  on 
  its 
  upper 
  surface. 
  They 
  are 
  

   rounded 
  pittings 
  varying 
  from 
  one 
  fourth 
  to 
  one 
  half 
  inch 
  in 
  

   diameter, 
  some 
  of 
  the 
  largest 
  being 
  fully 
  one 
  fourth 
  of 
  an 
  inch 
  in 
  

   depth. 
  The 
  opposite 
  side 
  of 
  the 
  layer, 
  which 
  is 
  nearly 
  one 
  half 
  

   inch 
  in 
  thickness, 
  shows 
  a 
  small 
  elevation 
  corresponding 
  to 
  the 
  

   hollow 
  on 
  the 
  upper 
  surface 
  These 
  markings 
  covered 
  quite 
  a 
  

   large 
  area 
  in 
  this 
  ledge, 
  and 
  what 
  is 
  probably 
  the 
  same 
  layer 
  

   was 
  discovered 
  later 
  in 
  a 
  ledge 
  on 
  Van 
  Dyke's 
  hill 
  about 
  one 
  

   fourth 
  of 
  a 
  mile 
  further 
  east.
