  This 
  is 
  the 
  highest 
  zone 
  of 
  Hamilton 
  fossils 
  found 
  on 
  the 
  hill 
  

   and 
  is 
  considered 
  to 
  mark 
  the 
  top 
  of 
  the 
  formation 
  above 
  which 
  

   are 
  the 
  shales 
  and 
  sandstones 
  of 
  the 
  Sherburne 
  formation. 
  

  

  Above 
  the 
  fossiliferous 
  zone 
  of 
  D 
  4 
  , 
  39 
  feet 
  of 
  the 
  smooth, 
  bluish, 
  

   argillaceous 
  shales 
  are 
  shown 
  along 
  the 
  quarry 
  road. 
  These 
  

   shales 
  which 
  weather 
  to 
  an 
  olive 
  tint 
  and 
  soon 
  decompose 
  into 
  

   soil 
  closely 
  resemble 
  in 
  lithologic 
  characters 
  the 
  Sherburne 
  

   shales, 
  to 
  the 
  base 
  of 
  which 
  formation 
  this 
  zone 
  is 
  referred. 
  The 
  

   rocks 
  are 
  then 
  covered 
  for 
  35 
  feet 
  when 
  the 
  base 
  of 
  the 
  McDonald 
  

   <& 
  Co's 
  flagstone 
  quarry 
  (D 
  7 
  ) 
  is 
  reached 
  near 
  the 
  top 
  of 
  the 
  hill. 
  

   There 
  are 
  12 
  feet 
  of 
  rather 
  coarse 
  grained, 
  blue 
  sandstone 
  shown 
  

   in 
  the 
  quarry 
  wall, 
  the 
  upper 
  three 
  feet 
  of 
  which 
  have 
  shaly 
  

   partings. 
  The 
  stone 
  is 
  quarried 
  for 
  flagging 
  though 
  some 
  of 
  the 
  

   layers 
  are 
  rather 
  thick. 
  The 
  sandstone 
  is 
  covered 
  by 
  38 
  feet 
  of 
  

   slightly 
  olive 
  and 
  bluish 
  argillaceous 
  shales, 
  (D 
  8 
  ) 
  at 
  the 
  western 
  

   end 
  of 
  the 
  quarry 
  and 
  31 
  feet 
  at 
  the 
  eastern 
  end, 
  containing 
  some 
  

   thin 
  layers 
  of 
  sandstone 
  and 
  all 
  weather 
  to 
  a 
  more 
  or 
  less 
  

   brownish 
  color. 
  At 
  one 
  place 
  on 
  the 
  floor 
  of 
  the 
  quarry 
  are 
  fine 
  

   ripple 
  marks. 
  Some 
  time 
  was 
  spent 
  in 
  hunting 
  for 
  fossils 
  over 
  

   the 
  large 
  amount 
  of 
  debris 
  from 
  the 
  quarry 
  but 
  nothing 
  save 
  a 
  

   few 
  rather 
  poorly 
  preserved 
  specimens 
  of 
  Lepidodendron 
  and 
  

   fragments 
  of 
  plant 
  stems 
  was 
  found. 
  From 
  the 
  top 
  of 
  the 
  quarry 
  

   to 
  the 
  summit 
  of 
  the 
  hill 
  is 
  some 
  20 
  feet 
  more, 
  all 
  of 
  which 
  is 
  

   covered. 
  On 
  the 
  top 
  of 
  the 
  hill 
  is 
  a 
  monument 
  of 
  the 
  New 
  York 
  

   state 
  topographical 
  survey 
  that 
  is 
  2428 
  feet 
  A. 
  T. 
  

  

  The 
  highway 
  was 
  followed 
  from 
  the 
  beginning 
  of 
  the 
  descent 
  

   to 
  Kichmondville 
  and 
  then 
  to 
  Warnerville 
  which 
  is 
  near 
  the 
  top 
  

   of 
  the 
  Onondaga 
  limestone. 
  Along 
  the 
  upper 
  part 
  of 
  the 
  hill 
  

   are 
  numerous 
  outcrops 
  of 
  Hamilton 
  shales 
  and 
  it 
  is 
  a 
  good 
  

   locality 
  at 
  which 
  to 
  study 
  the 
  upper 
  part 
  of 
  that 
  formation.
