  At 
  Monroe 
  several 
  of 
  the 
  streets 
  of 
  the 
  city 
  have 
  been 
  graveled 
  

   from 
  pits 
  on 
  the 
  Traveler's 
  Rest 
  stock 
  farm, 
  three 
  miles 
  north 
  

   of 
  town 
  on 
  the 
  west 
  bank 
  of 
  Ouachita 
  river. 
  This 
  gravel 
  has 
  

   also 
  been 
  used 
  in 
  the 
  concrete 
  work 
  of 
  the 
  new 
  bridge 
  over 
  the 
  

   Ouachita. 
  It 
  is 
  proposed 
  to 
  build 
  a 
  switch 
  to 
  this 
  deposit 
  from 
  the 
  

   V.

  The 
  V. 
  S. 
  & 
  P. 
  railroad 
  passes 
  through 
  a 
  portion 
  of 
  this 
  

   gravel 
  deposit 
  about 
  three 
  miles 
  west 
  of 
  Monroe, 
  and 
  has 
  

   removed 
  some 
  of 
  it 
  for 
  ballast 
  along 
  the 
  line. 
  The 
  Iron 
  Moun- 
  

   tain 
  railroad 
  has 
  obtained 
  a 
  small 
  quantity 
  of 
  gravel 
  from 
  the 
  

   deposits 
  in 
  the 
  northern 
  part 
  of 
  the 
  Grand 
  Gulf, 
  in 
  Grant 
  

   parish. 
  In 
  southern 
  Rapides, 
  according 
  to 
  Clendenin, 
  the 
  Kan- 
  

   sas 
  City, 
  Watkins 
  and 
  Gulf 
  railroad 
  has 
  obtained 
  large 
  quanti- 
  

   ties 
  of 
  gravel 
  for 
  road 
  ballast. 
  

  

  On 
  Belle 
  Isle 
  and 
  Petite 
  Anse 
  the 
  gravel 
  beds 
  have 
  been 
  utilized 
  

   in 
  making 
  concrete. 
  In 
  southern 
  Louisiana 
  good 
  sands 
  are 
  

   rarely 
  found. 
  Sands 
  occur 
  on 
  Petite 
  Anse 
  and 
  Grande 
  Cote, 
  in 
  

   situations 
  where 
  they 
  can 
  be 
  easily 
  dug, 
  and 
  the 
  sand-pits 
  at 
  these 
  

   two 
  places, 
  especially 
  the 
  former 
  because 
  of 
  its 
  railraad 
  connec- 
  

   tions, 
  supply 
  a 
  large 
  area 
  of 
  country.

  The 
  latter 
  part 
  of 
  1885 
  and 
  the 
  early 
  part 
  of 
  1886 
  were 
  spent 
  

   by 
  Mr. 
  L. 
  C. 
  Johnson, 
  of 
  the 
  U. 
  S. 
  Geological 
  Survey, 
  in 
  north- 
  

   ern 
  Louisiana, 
  in 
  investigating 
  the 
  iron 
  ores 
  of 
  that 
  region. 
  

   He 
  found 
  siderite 
  and 
  brown 
  hemitite 
  or 
  limonite 
  ores 
  in 
  the 
  

   form 
  of 
  nodules 
  or 
  concretions 
  and 
  thin 
  plates, 
  occuringin 
  nearly 
  

   all 
  of 
  the 
  beds 
  of 
  the 
  old 
  Tertiary, 
  and 
  occasionally 
  in 
  the 
  Lafay- 
  

   ette 
  sands. 
  These 
  ores 
  are 
  scattered 
  through 
  beds 
  of 
  sands 
  and 
  

   clays, 
  and 
  it 
  is 
  believed 
  that 
  they 
  can 
  hardly 
  be 
  obtained 
  in 
  

   sufiBcient 
  quantities 
  to 
  be 
  of 
  economic 
  value. 
  Selected 
  speci- 
  

   mens 
  give 
  very 
  good 
  results 
  when 
  submitted 
  to 
  analysis, 
  as 
  the 
  

   following 
  tables 
  will 
  show, 
  but 
  the 
  quantit}^ 
  of 
  ores 
  of 
  this 
  qual- 
  

   ity 
  seems 
  to 
  be 
  quite 
  limited.
