  was 
  observ^ed 
  in 
  a 
  meadow 
  opposite 
  tlie 
  Koman 
  eatliolic 
  clmrcli; 
  

   it 
  was 
  exposed 
  in 
  digging 
  drainage 
  trenches. 
  I^ear 
  this 
  locality, 
  

   but 
  a 
  little 
  nearer 
  the 
  river^ 
  were 
  found 
  several 
  mastodon 
  bones. 
  

  

  At 
  Jonespoint 
  there 
  was 
  formerly 
  a 
  small 
  deposit 
  of 
  clay, 
  but 
  it 
  

   has 
  been 
  entirely 
  worked 
  out. 
  

  

  Haverstraw 
  has 
  three 
  terraces, 
  viz, 
  at 
  20, 
  60 
  and 
  100 
  feet. 
  

   The 
  clay 
  so 
  far 
  as 
  known 
  is 
  only 
  found 
  underlying 
  the 
  two 
  lower 
  

   ones, 
  the 
  upper 
  one 
  being 
  underlain 
  by 
  drift 
  and 
  delta 
  deposits. 
  

  

  There 
  is 
  a 
  deposit 
  of 
  clay 
  at 
  Stonypoint 
  forming 
  a 
  portion 
  of 
  the 
  

   20 
  foot 
  terrace. 
  The 
  upper 
  layers 
  of 
  clay 
  are 
  in 
  places 
  loamy 
  and 
  

   undulating. 
  Over 
  the 
  clay 
  is 
  a 
  mass 
  of 
  unstratified 
  material 
  from 
  

   2 
  to 
  8 
  feet 
  thick, 
  and 
  the 
  upper 
  surface 
  of 
  the 
  clay 
  is 
  uneven. 
  

   The 
  overlying 
  unstratified 
  material 
  is 
  a 
  coarse 
  sand 
  full 
  of 
  cobble- 
  

   stones, 
  gneiss, 
  schist 
  and 
  granite, 
  all 
  of 
  them 
  rounded 
  but 
  not 
  

   scratched. 
  On 
  the 
  hillside 
  to 
  the 
  west 
  of 
  this 
  deposit 
  is 
  a 
  large, 
  

   isolated 
  boulder 
  of 
  granite. 
  The 
  upper 
  terrace 
  at 
  Stonypoint 
  is 
  

   about 
  75 
  feet 
  higher 
  than 
  the 
  station 
  level; 
  a 
  portion 
  of 
  this 
  terrace 
  

   remains 
  about 
  one 
  eighth 
  of 
  a 
  mile 
  north 
  of 
  Stonypoint 
  station 
  on 
  

   the 
  west 
  side 
  of 
  the 
  track. 
  On 
  the 
  west 
  side 
  of 
  the 
  track 
  where 
  it 
  

   crosses 
  Cedar 
  Fond 
  brook 
  the 
  delta 
  structure 
  is 
  observable 
  in 
  the 
  

   embankment, 
  the 
  upper 
  portion 
  of 
  which 
  consists 
  of 
  coarse 
  sand, 
  

   pebbles 
  and 
  cobblestones 
  which 
  are 
  mostly 
  of 
  gneiss. 
  The 
  lower 
  

   layers 
  exposed 
  at 
  this 
  point 
  are 
  quite 
  argillaceous. 
  A 
  short 
  distance 
  

   below 
  the 
  "West 
  Haverstraw 
  station 
  and 
  some 
  500 
  feet 
  west 
  of 
  the 
  

   track, 
  an 
  excavation 
  had 
  been 
  made 
  for 
  tempering 
  material. 
  It 
  

   exposes 
  a 
  fine 
  yellowish 
  cross-stratified 
  sand 
  overlain 
  by 
  several 
  feet 
  

   of 
  coarse 
  sand 
  and 
  cobblestones. 
  

  

  In 
  T. 
  Malley's 
  clay 
  bank 
  along 
  the 
  shore 
  on 
  the 
  north 
  side 
  of 
  

   G-rassy 
  point, 
  the 
  clay 
  is 
  not 
  found 
  above 
  tide 
  level 
  and 
  is 
  

   overlain 
  by 
  3 
  to 
  4 
  feet 
  of 
  fine 
  gravel. 
  To 
  the 
  northeast 
  of 
  

   P. 
  Brophy's 
  yard 
  is 
  the 
  remnant 
  of 
  a 
  terrace. 
  It 
  is 
  composed 
  of 
  

   obscurely 
  cross-stratified 
  sand 
  and 
  gravel, 
  overlain 
  by 
  a 
  few 
  feet 
  

   of 
  loamy 
  clay, 
  very 
  thinly 
  stratified 
  and 
  the 
  layers 
  wavy. 
  There 
  

   is 
  a 
  boulder 
  of 
  norite 
  in 
  this 
  bank; 
  there 
  are 
  also 
  cobblestones 
  of
