  Port 
  Ewen, 
  Ulster 
  co. 
  S. 
  D. 
  Coykendairs 
  yard 
  lies 
  near 
  the 
  

   junction 
  of 
  Kondout 
  creek 
  and 
  Hudson 
  river. 
  The 
  bank 
  is 
  just 
  

   west 
  of 
  the 
  yard. 
  There 
  is 
  a 
  considerable 
  stripping 
  of 
  fine 
  sand 
  

   and 
  the 
  clay 
  slides 
  quite 
  easily. 
  It 
  is 
  dug 
  at 
  any 
  convenient 
  point 
  

   of 
  the 
  bank. 
  The 
  overlying 
  sand 
  can 
  be 
  used 
  for 
  tempering 
  and 
  

   molding. 
  Oil 
  is 
  used 
  for 
  burning 
  the 
  bricks. 
  A 
  short 
  distance 
  

   farther 
  south 
  along 
  the 
  river 
  is 
  J. 
  Kline's 
  yard. 
  He 
  obtains 
  his 
  

   clay 
  from 
  various 
  points 
  in 
  the 
  terrace 
  escarpment 
  and 
  in 
  some 
  

   cases 
  hauls 
  it 
  nearly 
  a 
  quarter 
  of 
  a 
  mile. 
  Mr 
  Kline 
  has 
  made 
  

   borings 
  at 
  various 
  points 
  along 
  the 
  river 
  and 
  the 
  terrace 
  and 
  in 
  the 
  

   escarpment 
  in 
  the 
  vicinity 
  of 
  his 
  yard, 
  and 
  says 
  that 
  at 
  none 
  of 
  them 
  

   has 
  he 
  found 
  over 
  18 
  feet 
  of 
  clay. 
  Beneath 
  it 
  was 
  hardpan. 
  This 
  

   would 
  seem 
  to 
  indicate 
  that 
  the 
  central 
  mass 
  of 
  the 
  embankment 
  is 
  

   rock, 
  overlain 
  by 
  hardpan, 
  and 
  that 
  on 
  this 
  the 
  clay 
  is 
  laid 
  down. 
  

   In 
  many 
  places 
  the 
  clay 
  is 
  covered 
  by 
  10 
  to 
  20 
  feet 
  of 
  fine, 
  strati- 
  

   fied 
  sand.
