  searcli, 
  find 
  the 
  material 
  most 
  suited 
  to 
  his 
  needs. 
  In 
  several 
  plants 
  

   already 
  established 
  the 
  plastic 
  clays 
  have 
  been 
  given 
  np 
  for 
  shale, 
  

   this 
  being 
  true 
  not 
  only 
  of 
  works 
  where 
  ornamental 
  wares 
  are 
  made, 
  

   but 
  also 
  of 
  those 
  manufacturing 
  common 
  brick. 
  

  

  "Next 
  to 
  the 
  shale 
  deposits 
  it 
  is 
  probable 
  that 
  the 
  clay 
  beds 
  of 
  

   Long 
  Island 
  have 
  the 
  most 
  promising 
  future. 
  It 
  is 
  true 
  that 
  they 
  

   are 
  at 
  times 
  pockety 
  and 
  the 
  overburden 
  is 
  often 
  considerable, 
  but 
  

   nevertheless 
  there 
  is 
  an. 
  abundance 
  of 
  material 
  of 
  gopd 
  quality. 
  

  

  Another 
  noteworthy 
  feature 
  of 
  the 
  industrj^ 
  is 
  the 
  adoption 
  of 
  

   more 
  modem 
  methods 
  of 
  molding 
  and 
  burning. 
  Dry 
  press 
  and 
  stiff 
  

   mud 
  machines 
  are 
  frequently 
  met 
  A^ith 
  where 
  they 
  were 
  not 
  seen 
  

   six 
  years 
  ago. 
  There 
  is 
  also 
  progress 
  in 
  the 
  use 
  of 
  the 
  most 
  approved 
  

   kilns, 
  and 
  those 
  of 
  the 
  continuous 
  type 
  are 
  gaining 
  specially 
  in 
  

   favor. 
  Six 
  years 
  ago 
  there 
  was 
  not 
  one 
  in 
  use 
  in 
  the 
  state. 
  

  

  Many 
  of 
  the 
  analyses 
  given 
  in 
  the 
  report 
  are 
  new, 
  and 
  a 
  number 
  

   of 
  physical 
  tests 
  haA^e 
  been 
  made, 
  particularly 
  on 
  the 
  shales, 
  in 
  order 
  

   that 
  they 
  may 
  be 
  compared 
  intelligently 
  with 
  some 
  used 
  in 
  the 
  

   manufacture 
  of 
  standard 
  products 
  at 
  other 
  localities. 
  

  

  Thanks 
  are 
  due 
  to 
  the 
  many 
  manufacturers 
  who 
  have 
  kindly 
  

  

  given 
  aid 
  and 
  information 
  in 
  the 
  preparation 
  of 
  this 
  bulletin, 
  and 
  

  

  through 
  their 
  liberality 
  it 
  has 
  been 
  possible 
  to 
  give 
  many 
  of 
  the 
  

  

  illustrations 
  which 
  accompany 
  the 
  text.
