  part 
  of 
  the 
  hill 
  only 
  ledges 
  of 
  gray, 
  thin 
  bedded 
  sandstone 
  

   were 
  seen 
  in 
  place. 
  Some 
  of 
  the 
  grayish 
  sandstone 
  shows 
  

   fine 
  examples 
  of 
  oblique 
  bedding. 
  Near 
  the 
  top 
  of 
  the 
  hill 
  

   part 
  of 
  the 
  sandstone 
  is 
  of 
  greenish 
  gray 
  color 
  and 
  a 
  specimen 
  

   was 
  found 
  containing 
  Amnigenia 
  catskillensis 
  (Van.) 
  Hall, 
  which 
  

   apparently 
  came 
  from 
  one 
  of 
  the 
  greenish 
  layers. 
  On 
  the 
  surface 
  

   is 
  an 
  abundance 
  of 
  loose, 
  red 
  rock 
  which 
  must 
  have 
  formerly 
  

   capped 
  the 
  hill, 
  but 
  none 
  was 
  found 
  in 
  place. 
  Mr 
  Fisher 
  has 
  

   given 
  some 
  time 
  to 
  the 
  study 
  of 
  the 
  geology 
  of 
  the 
  southern 
  part 
  

   of 
  Davenport 
  and 
  he 
  has 
  kindly 
  contributed 
  the 
  following 
  notes: 
  

  

  The 
  townships 
  of 
  Davenport 
  and 
  Harpersfield 
  form 
  the 
  extreme 
  

   northeastern 
  portion 
  of 
  Delaware 
  county. 
  The 
  country 
  is 
  hilly, 
  

   but 
  the 
  hills 
  are 
  neither 
  so 
  high 
  nor 
  so 
  steep 
  as 
  those 
  in 
  the 
  more 
  

   central 
  and 
  eastern 
  part 
  of 
  the 
  county. 
  They 
  are 
  drained 
  by 
  the 
  

   Charlotte 
  river 
  and 
  its 
  branches, 
  the 
  river 
  itself 
  being 
  a 
  tributary 
  

   of 
  the 
  Susquehanna. 
  

  

  The 
  low 
  ground 
  in 
  the 
  valley 
  of 
  the 
  Charlotte, 
  and 
  the 
  bases 
  of 
  

   the 
  hills 
  on 
  either 
  side 
  of 
  it, 
  are 
  made 
  up 
  of 
  rocks 
  of 
  the 
  Ithaca 
  

   formation. 
  The 
  tops 
  of 
  the 
  hills 
  are 
  capped 
  with 
  the 
  heavy 
  

   sandstones 
  of 
  the 
  Oneonta 
  formation. 
  

  

  The 
  lower 
  part 
  of 
  the 
  valley, 
  between 
  West 
  Davenport 
  and 
  

   Davenport 
  Center, 
  was 
  searched 
  pretty 
  carefully, 
  but 
  very 
  few 
  

   exposures 
  of 
  rock 
  in 
  place 
  were 
  found. 
  The 
  country 
  is 
  very 
  

   largely 
  covered 
  with 
  drift 
  and 
  soil, 
  so 
  that 
  even 
  the 
  deeper 
  cuts 
  

   along 
  the 
  line 
  of 
  the 
  Cooperstown 
  and 
  Charlotte 
  Valley 
  railroad 
  

   expose 
  only 
  thick 
  beds 
  of 
  sand 
  and 
  coarse 
  gravel. 
  The 
  loose 
  stones 
  

   found 
  along 
  the 
  roadsides 
  and 
  in 
  the 
  bed 
  of 
  the 
  creek, 
  which 
  

   are 
  greenish 
  gray 
  shales 
  and 
  soft 
  gray 
  or 
  brown 
  sandstone, 
  are 
  

   very 
  fossiliferous, 
  and 
  from 
  these 
  loose 
  pieces 
  the 
  following 
  Ithaca 
  

   fossils 
  were 
  collected.
