  Most 
  of 
  tlie 
  clay 
  deposits 
  of 
  this 
  state 
  are 
  surface 
  beds 
  of 
  Quat- 
  

   ernary 
  age. 
  The 
  loess 
  is 
  extensively 
  used 
  in 
  the 
  eastern 
  counties; 
  

   at 
  Pittsburg 
  a 
  10 
  foot 
  bed 
  of 
  Carboniferous 
  shale 
  occurs, 
  which 
  is 
  

   used 
  for 
  the 
  manufacture 
  of 
  fire 
  brick 
  and 
  paving 
  brick. 
  Fire 
  

   clays 
  also 
  occur 
  at 
  a 
  number 
  of 
  other 
  localities 
  in 
  association 
  with 
  

   the 
  coal 
  beds, 
  but 
  they 
  have 
  not 
  been 
  used 
  to 
  any 
  great 
  extent. 
  

  

  Kentuchy 
  

  

  The 
  state 
  of 
  Kentucky 
  contains 
  numerous 
  clay 
  deposits, 
  many 
  

   of 
  them 
  of 
  excellent 
  quality. 
  

  

  They 
  are 
  found 
  in 
  several 
  geologic 
  formations, 
  beginning 
  with 
  

   the 
  Cretaceous, 
  of 
  western 
  Kentucky, 
  which 
  shows 
  an 
  abundance 
  

   of 
  brick 
  clay, 
  fire 
  clay 
  and 
  pottery 
  clays. 
  

  

  In 
  the 
  Cretaceous 
  and 
  the 
  Coal 
  Measures, 
  clay 
  suitable 
  for 
  

   making 
  vitrified 
  brick 
  as 
  well 
  as 
  fire 
  brick, 
  occurs. 
  

  

  Fire 
  clay 
  is 
  found 
  in 
  Carter 
  co., 
  where 
  it 
  is 
  now 
  being 
  mined 
  and 
  

   carried 
  to 
  Louisville 
  for 
  manufacture. 
  Similar 
  clays 
  are 
  known 
  

   in 
  the 
  counties 
  of 
  Ballard, 
  Muhlenberg, 
  Grayson, 
  Edmonson, 
  

   Graves, 
  Hickman, 
  Calloway, 
  Fulton, 
  Bell, 
  Boyd. 
  Most 
  of 
  these 
  

   clays 
  are 
  said 
  to 
  run 
  high 
  in 
  silica 
  and 
  alumina 
  and 
  low 
  in 
  fluxes. 
  

  

  The 
  clay 
  from 
  Graham 
  station, 
  in
