  Station 
  3. 
  Dry 
  creek, 
  Watervliet 
  

  

  The 
  writer 
  has 
  been 
  unable 
  to 
  find 
  another 
  locality 
  with 
  as 
  

   complete 
  a 
  fauna 
  as 
  this 
  going 
  southward 
  in 
  the 
  strike 
  of 
  the 
  

   beds 
  of 
  Cohoes. 
  This 
  is 
  partly 
  due 
  to 
  the 
  lack 
  of 
  outcrops 
  of 
  

   these 
  beds, 
  caused 
  by 
  the 
  general 
  n 
  ne-s 
  sw 
  strike 
  of 
  the 
  

   Hudson 
  river 
  shales, 
  which 
  carries 
  these 
  Lorraine 
  beds 
  under 
  

   the 
  drift-covered 
  plateau 
  to 
  the 
  west 
  of 
  the 
  Hudson 
  river. 
  Fol- 
  

   lowing 
  the 
  edge 
  of 
  the 
  plateau 
  about 
  3 
  miles 
  to 
  the 
  southwest, 
  

   a 
  large 
  outcrop 
  is 
  met 
  with 
  (station 
  3) 
  along 
  Dry 
  creek, 
  west 
  of 
  

   Green 
  Island. 
  This 
  creek 
  has 
  formed 
  a 
  deep 
  gorge 
  through 
  a 
  

   homogeneous 
  mass 
  of 
  soft 
  gray 
  argillaceous 
  shales. 
  In 
  these 
  

   beds 
  only 
  a 
  single 
  layer 
  with 
  fossils 
  was 
  found. 
  There 
  were 
  a 
  

   few 
  specimens 
  of 
  Corynoides 
  curtus 
  and 
  more 
  abundant 
  

   stipes 
  of 
  Diplograptus 
  foliaceus. 
  The 
  writer 
  colors 
  

   station 
  3 
  (Dry 
  creek) 
  as 
  a 
  Lorraine 
  station, 
  as 
  the 
  two 
  graptolites 
  

   are 
  of 
  themselves 
  noncommittal, 
  while 
  the 
  beds 
  by 
  their 
  extreme 
  

   barrenness 
  suggest 
  their 
  Lorraine 
  age 
  and 
  also 
  lie 
  in 
  the 
  strike 
  

   of 
  the 
  Cohoes 
  rocks. 
  

  

  Station 
  4. 
  South 
  Cohoes 
  

  

  The 
  reconstruction 
  of 
  a 
  sidewalk 
  in 
  south 
  Cohoes 
  brought 
  out 
  

   a 
  considerable 
  mass 
  of 
  rock, 
  which 
  like 
  that 
  of 
  Dry 
  creek 
  (station 
  

   3) 
  consisted 
  mostly 
  of 
  compact 
  dark 
  gray 
  to 
  black, 
  argillaceous 
  

   shales 
  with 
  very 
  few 
  specimens 
  of 
  Diplograptus 
  foli- 
  

   aceus 
  and 
  Corynoides 
  curtus. 
  

  

  Other 
  outcrops 
  of 
  Lorraine 
  beds 
  

  

  No 
  outcrops 
  of 
  rocks 
  which 
  by 
  their 
  fossil 
  contents 
  could 
  be 
  

   attributed 
  to 
  the 
  Lorraine 
  age 
  were 
  found 
  to 
  the 
  northwest 
  and 
  

   west 
  of 
  Albany, 
  as 
  the 
  brooks 
  have 
  nowhere 
  cut 
  through 
  the 
  

   heavy 
  drift 
  covering 
  to 
  the 
  bed 
  rocks. 
  This 
  is 
  specially 
  observa- 
  

   ble 
  along 
  the 
  northern 
  affluents 
  of 
  the 
  Normans 
  kill. 
  The 
  next 
  

   outcrops 
  occur 
  along 
  the 
  Vly, 
  a 
  southern 
  tributary 
  of 
  the 
  Nor- 
  

   mans 
  kill, 
  at 
  the 
  sawmill 
  below 
  Voorheesville, 
  7 
  miles 
  west 
  of
