   had 
  a

  60 
  men 
  at 
  the

  Small 
  quarries 
  have 
  been 
  opened 
  here 
  to 
  obtain 
  

   stone 
  for 
  Government 
  crib

  Petite

  — 
  In 
  Iron 
  Mine 
  Run 
  on 
  Petite 
  Anse 
  there 
  is 
  

  

  exposed 
  a 
  soft 
  pink 
  sandstone 
  which 
  may 
  be 
  of 
  value 
  for 
  railroad 
  

  

  ballast. 
  The 
  surface 
  indications, 
  however, 
  seem 
  to 
  show 
  that 
  it 
  

  

  is 
  rather 
  soft. 
  

  

  Limestone 
  

  

  lyimestone 
  occurs 
  in 
  Louisiana 
  in 
  beds 
  of 
  limited 
  extent, 
  and 
  

   also 
  in 
  the 
  form 
  of 
  concretions. 
  

  

  Cretaceous 
  litnestones. 
  — 
  The 
  beds 
  of 
  limestone 
  seem 
  to 
  be 
  

   almost 
  entirely 
  confinefl 
  to 
  the 
  Cretaceous. 
  Of 
  the 
  three 
  

   outcrops 
  which 
  occur 
  in 
  the 
  State, 
  the 
  Winnfield 
  limestone 
  

   is 
  of 
  very 
  doubtful 
  value 
  as 
  a 
  building 
  stone, 
  but 
  the 
  Coochie 
  

   Brake 
  and 
  Bayou 
  Chicot 
  deposit 
  may 
  be 
  utilized 
  for 
  that 
  purpose. 
  

  

  The 
  Winnfield 
  limestone 
  is 
  a 
  highly 
  crystalline 
  blue 
  and 
  white 
  

   banded 
  stone. 
  It 
  is 
  full 
  of 
  cracks 
  and 
  pockets 
  and 
  other 
  flaws, 
  

   which 
  will 
  render 
  it 
  useless 
  as 
  an 
  ornamental 
  or 
  building 
  stone. 
  

   It 
  can 
  doubtless 
  be 
  used 
  to 
  advantage 
  for 
  making 
  lime. 
  The 
  

   quantity 
  of 
  the 
  stone 
  in 
  sight 
  is 
  large 
  and 
  it 
  can 
  be 
  very 
  econom- 
  

   ically 
  quarried. 
  Several 
  kilns 
  of 
  lime 
  have 
  already 
  been 
  burned 
  

   here 
  for 
  local 
  use. 
  

  

  The 
  purity 
  of 
  the 
  stone 
  is 
  shown

  the 
  following
