  that 
  very 
  curious 
  crossbedding 
  which 
  is 
  characteristic 
  of 
  the 
  

   Oneonta, 
  and 
  which 
  is 
  mentioned 
  by 
  both 
  Mather 
  and 
  Vanuxem 
  

   in 
  the 
  New 
  York 
  state 
  reports 
  . 
  

  

  71 
  feet 
  covered, 
  brings 
  us 
  to 
  a 
  15-foot 
  ledge 
  of 
  coarse, 
  thin 
  

   bedded 
  gray 
  sandstone 
  on 
  the 
  hillside 
  just 
  in 
  front 
  of 
  the 
  home 
  

   of 
  Mr 
  Elmer 
  Hall. 
  This 
  ledge, 
  like 
  all 
  the 
  others 
  on 
  this 
  hill, 
  

   shows 
  no 
  fossils 
  except 
  occasional 
  fragments 
  of 
  plant 
  stems, 
  but 
  

   in 
  lithologic 
  character 
  the 
  rocks 
  agree 
  perfectly 
  with 
  the 
  typical 
  

   Oneonta 
  found 
  in 
  other 
  portions 
  of 
  the 
  county. 
  

  

  Above 
  this 
  ledge 
  there 
  is 
  five 
  feet 
  covered 
  and 
  then 
  a 
  ledge 
  of 
  

   five 
  feet 
  of 
  red 
  sandstone. 
  

  

  45 
  feet 
  covered, 
  five 
  feet 
  of 
  gray 
  sandstone, 
  and 
  10 
  feet 
  covered 
  

   brings 
  us 
  to 
  the 
  top 
  of 
  the 
  hill, 
  which 
  is 
  the 
  highest 
  point 
  of 
  

   ground 
  on 
  the 
  divide 
  between 
  Elk 
  creek 
  and 
  Honest 
  brook. 
  

  

  It 
  will 
  be 
  noticed 
  by 
  referring 
  to 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  

   that 
  Mr 
  Darton 
  claims 
  a 
  large 
  island 
  of 
  Chemung 
  rock 
  covering 
  

   the 
  top 
  of 
  the 
  hill 
  between 
  these 
  two 
  streams. 
  The 
  island 
  as 
  he 
  

   represents 
  it 
  should 
  be 
  about 
  four 
  miles 
  long 
  by 
  one 
  mile 
  wide, 
  

   and 
  at 
  least 
  200 
  feet 
  in 
  thickness. 
  A 
  very 
  careful 
  search 
  failed 
  

   to 
  reveal 
  anything 
  in 
  the 
  nature 
  of 
  Chemung 
  as 
  characterized 
  

   either 
  by 
  its 
  fossils 
  or 
  by 
  its 
  lithology. 
  The 
  rocks, 
  as 
  indicated 
  

   by 
  the 
  section, 
  being 
  the 
  coarse 
  red 
  and 
  'gray 
  sandstone 
  showing 
  

   all 
  the 
  features 
  of 
  the 
  typical 
  Oneonta. 
  

  

  From 
  this 
  station 
  a 
  trip 
  was 
  made 
  over 
  onto 
  the 
  hill 
  lying 
  

   between 
  the 
  east 
  and 
  west 
  branches 
  of 
  Honest 
  brook 
  where 
  Dar- 
  

   ton 
  claims 
  another 
  island 
  of 
  Chemung; 
  somewhat 
  smaller 
  than 
  

   the 
  other, 
  but 
  yet 
  about 
  two 
  miles 
  in 
  length. 
  The 
  work 
  here 
  

   met 
  with 
  the 
  same 
  result 
  as 
  that 
  on 
  Hall's 
  hill, 
  in 
  that 
  it 
  proved 
  

   that 
  the 
  island 
  of 
  Chemung 
  does 
  not 
  exist. 
  The 
  three 
  small 
  

   ledges 
  which 
  were 
  found 
  bear 
  unmistakable 
  evidence 
  that 
  the 
  

   rock 
  is 
  all 
  of 
  the 
  Oneonta 
  formation. 
  

  

  These 
  islands, 
  as 
  well 
  as 
  the 
  four 
  others 
  which 
  Mr 
  Darton 
  

   represents 
  on 
  his 
  map, 
  must 
  have, 
  been 
  placed 
  here 
  simply 
  on 
  

   account 
  of 
  the 
  altitude 
  of 
  the 
  hills 
  and 
  the 
  supposed 
  stratigraphic 
  

   position 
  of 
  the 
  Chemung 
  formation, 
  and 
  with 
  no 
  reference 
  to 
  the 
  

   thinning 
  out 
  of 
  this 
  formation 
  in 
  the 
  western 
  part 
  of 
  the 
  county, 
  

   nor 
  to 
  its 
  entire 
  disappearance 
  before 
  it 
  reaches 
  Delhi. 
  

  

  The 
  next 
  section 
  is 
  the 
  one 
  called 
  the 
  Fish's 
  quarry 
  section. 
  

   It 
  starts 
  at 
  the 
  river 
  near 
  Mr 
  D. 
  L. 
  Wight's 
  farm 
  and 
  extends 
  to 
  

   the 
  top 
  of 
  the 
  hill 
  west 
  of 
  Meredith 
  street 
  in 
  the 
  northern 
  end 
  

   of 
  the 
  village 
  of 
  Delhi. 
  It 
  will 
  be 
  noticed, 
  by 
  comparing 
  this 
  

   section 
  with 
  that 
  of 
  65 
  E, 
  that 
  the 
  rocks 
  represented 
  in 
  this 
  cor- 
  

   respond 
  in 
  elevation 
  to 
  the 
  490 
  feet 
  represented 
  as 
  covered 
  be- 
  

   tween 
  the 
  rocks 
  in 
  Watauga 
  Falls 
  and 
  the 
  lowest 
  ledge
