  some

  sandy. 
  It 
  has 
  

   been 
  bored 
  to 
  a 
  depth 
  of 
  60 
  feet 
  in 
  places, 
  but 
  this 
  depth 
  is 
  not 
  con- 
  

   stant, 
  and 
  in 
  spots 
  the 
  underlying 
  limestone 
  rises 
  to 
  within 
  a 
  few 
  

   feet 
  of 
  the 
  surface. 
  The 
  sand 
  for 
  tempering 
  has 
  to 
  be 
  brought 
  2 
  

   miles. 
  The

  The

  miles 
  north 
  of 
  the 
  depot 
  is 
  

   the

  The 
  clay 
  is 
  of 
  a 
  blue 
  color 
  and 
  

   about 
  20 
  feet

  The 
  clay 
  has 
  to 
  be 
  tempered 
  with 
  sand. 
  

   Drying 
  is 
  done 
  on 
  pallets

  in 
  the

  Burning 
  takes 
  about 
  one 
  

   week.

  William

  The 
  clay 
  bank 
  

   lies 
  on 
  the 
  east 
  side 
  of 
  the 
  Racket 
  river. 
  It 
  is 
  about 
  25 
  feet 
  

   in 
  thickness 
  and 
  there 
  is 
  a 
  covering 
  of 
  12 
  feet 
  of 
  fine 
  sand. 
  The 
  

   clay 
  is 
  rather 
  tough 
  and 
  requires 
  an 
  admixture 
  about 
  one 
  third 
  sand 
  

   for 
  making 
  brick. 
  An 
  abundance 
  of 
  unworked 
  clay 
  is 
  still 
  in 
  sight.
