  Brigham 
  Bros.' 
  yard 
  the 
  clay 
  is 
  yellow, 
  being 
  weathered 
  through 
  

   to 
  its 
  base. 
  It 
  has 
  a 
  thickness 
  of 
  10 
  feet 
  and 
  rests 
  on 
  an 
  uneven 
  

   ridge 
  of 
  shale. 
  On 
  account 
  of 
  its 
  toughness 
  it 
  is 
  worked 
  by 
  under- 
  

   mining, 
  as 
  is 
  the 
  case 
  with 
  other 
  yards 
  along 
  here 
  where 
  clay 
  is 
  

   being 
  dug. 
  C. 
  A. 
  Schultz 
  has 
  ian 
  exposure 
  of 
  clay 
  80 
  feet 
  thick, 
  

   overlain 
  in 
  spots 
  by 
  sand 
  that 
  can 
  be 
  used 
  for 
  tempering. 
  I^ext 
  

   on 
  the 
  south 
  is 
  A. 
  S. 
  Staples's 
  yard. 
  The 
  bank 
  has 
  been 
  excavated 
  

   to 
  a 
  lower 
  level 
  than 
  the 
  preceding 
  one. 
  The 
  clay 
  is 
  underlain 
  by 
  

   hardpan.

  E,. 
  Maine 
  & 
  Co. 
  have 
  five 
  acres 
  of 
  clay 
  land. 
  The 
  ter- 
  

   race 
  here 
  is 
  quite 
  narrow. 
  At 
  Terry 
  Bros.' 
  yard 
  the 
  clay, 
  which 
  

   is 
  mostly 
  blue, 
  has 
  been 
  excavated 
  sufficiently 
  to 
  expose 
  the 
  lime- 
  

   stone 
  against 
  which 
  the 
  terrace 
  lies. 
  At 
  Hutton's 
  yard 
  the 
  blue 
  

   clay 
  is 
  exposed 
  from 
  8 
  feet 
  above 
  mean 
  tide, 
  to 
  110 
  feet 
  above 
  

   it; 
  overlying 
  this 
  is 
  10 
  feet 
  of 
  yellow 
  clay 
  and 
  then 
  15 
  feet 
  of 
  sand. 
  

   It 
  will 
  be 
  seen 
  from 
  the 
  limits 
  quoted 
  above 
  and 
  in 
  the 
  table, 
  that 
  

   the 
  thickness 
  of 
  the 
  clay 
  between 
  Glasco 
  and 
  Rondout 
  varies 
  con- 
  

   siderably, 
  amounting 
  to 
  120 
  feet 
  in 
  places, 
  while 
  in 
  others 
  it 
  is 
  

   not 
  over 
  15 
  or 
  20 
  feet. 
  This 
  is 
  due 
  to 
  the 
  great 
  irregularity 
  of 
  the 
  

   underlying 
  rock 
  surface.
