  The 
  processes 
  are 
  not 
  wholly 
  distinct 
  from 
  esLch 
  other, 
  as 
  there 
  

   are 
  machines 
  that 
  may 
  be 
  nsed 
  as 
  well 
  in 
  connection 
  wi<th 
  one 
  as 
  

   the 
  other. 
  For 
  instance, 
  in 
  preparing 
  the 
  clay 
  for 
  molding 
  in 
  a 
  

   stiff 
  mud 
  machine, 
  we 
  may 
  use 
  either 
  a 
  pug 
  mill 
  or 
  a 
  pan 
  crusher, 
  

   though 
  the 
  latter 
  belongs 
  preferably 
  to 
  the 
  dry 
  clay 
  process. 
  What- 
  

   ever 
  be 
  the 
  method, 
  the 
  manufacture 
  of 
  clay 
  intO' 
  brick 
  involves 
  the 
  

   following 
  steps, 
  preparation, 
  molding, 
  drying, 
  burning. 
  Below 
  is 
  

   a 
  classified 
  arrangement 
  of 
  the 
  stages 
  in 
  the 
  process 
  of 
  brickmaking 
  

  

  and 
  machines 
  used.
