  About 
  half 
  a 
  mile 
  from 
  Syke's 
  ferry 
  the 
  road 
  enters 
  the 
  level 
  

   second 
  bottom. 
  Natural 
  mounds 
  are 
  quite 
  numerous. 
  The 
  soil 
  

   varies 
  from 
  a 
  gray 
  clay 
  to 
  a 
  pure 
  gray 
  sand. 
  

  

  The 
  present 
  bottom 
  of 
  Bayou 
  Dauchite 
  is 
  about 
  half 
  a 
  mile 
  

   wide 
  and 
  at 
  Syke's 
  Ferry 
  is 
  on 
  the 
  west 
  side 
  of 
  the 
  Bayou. 
  

   From 
  Serepta 
  to 
  Cotton 
  valley 
  the 
  relief 
  is 
  very 
  small 
  indeed. 
  

   The 
  prevailing 
  soil 
  is 
  a 
  pure 
  gray 
  sand. 
  

  

  Johnson 
  describes 
  briefly 
  the 
  iron 
  ores 
  of 
  this 
  parish, 
  and 
  

   determines 
  their 
  age 
  as 
  follows 
  : 
  From

   }( 
  Sec. 
  i6,

  W., 
  and 
  in 
  S.

  same

  and 
  range, 
  

   and 
  in 
  S. 
  25, 
  21 
  N., 
  9 
  W., 
  it 
  appears 
  that 
  these 
  red 
  lands 
  are 
  the 
  

   outcropping 
  of 
  Claiborne 
  marls, 
  rich 
  in 
  greensand, 
  which 
  were 
  

   traced 
  northward 
  from 
  Minden. 
  

  

  (Claiborne 
  Parish) 
  

  

  Lisbon. 
  — 
  Around 
  Lisbon 
  is 
  a 
  red 
  sandy 
  clay 
  soil, 
  apparently 
  of 
  

   considerable 
  agricultural 
  value, 
  for 
  the 
  country 
  looks 
  like 
  a 
  very 
  

   thrifty 
  prosperous 
  strip 
  of 
  land. 
  The 
  larger 
  creeks 
  have 
  great 
  

   flat 
  bottoms. 
  Middle 
  Fork 
  bottom 
  is 
  in 
  this 
  region 
  about 
  

   a 
  mile 
  and 
  a 
  half 
  wide. 
  It 
  is 
  partly 
  in 
  cultivation. 
  The 
  hills 
  

   on 
  the 
  southern 
  portion 
  of 
  the 
  bottoms 
  have 
  a 
  height 
  of 
  about 
  

   100 
  feet. 
  Some 
  of 
  the 
  ironstone 
  concretions 
  which 
  occur 
  in 
  this 
  

   region, 
  when 
  broken 
  open, 
  contain 
  a 
  nucleus 
  of 
  gray 
  phosphate 
  

   of 
  lime. 
  Several 
  of 
  these 
  concretions 
  were 
  picked 
  up 
  on 
  the 
  

   hills 
  on 
  the 
  south 
  side 
  of 
  Middle 
  Fork 
  bottoms 
  and 
  on 
  McGar- 
  

   land's 
  creek 
  ; 
  and, 
  Mr, 
  Maurice 
  Bird 
  of 
  the 
  North 
  Louisiana 
  

   Experiment 
  Station 
  has 
  shown 
  that 
  the 
  concretions 
  contain 
  

   from 
  15 
  to 
  20 
  per 
  cent 
  of 
  phosphoric 
  acid. 
  It 
  is 
  hoped 
  that 
  

   larger 
  deposits 
  of 
  these 
  may 
  be 
  found. 
  

  

  Haynesville. 
  — 
  Around 
  Haynesville 
  the 
  topographic 
  relief 
  is 
  

   not 
  so 
  great 
  as 
  farther 
  east. 
  Gray 
  sands 
  and 
  clays 
  occur 
  in 
  the 
  

   road 
  cuts, 
  and 
  gravel 
  crops 
  out 
  on 
  the 
  hillsides. 
  

  

  Homer. 
  — 
  Six 
  miles 
  northwest 
  of 
  Homer 
  on 
  the 
  Homer- 
  

   Haynesville 
  road 
  the 
  light 
  gray 
  sands 
  of 
  the 
  Gordon 
  region 
  are 
  

   replaced 
  by 
  red 
  lands. 
  These 
  red 
  lands 
  occur 
  with 
  scarcely 
  an 
  

   interruption 
  to 
  Homer. 
  At 
  Homer 
  the 
  railroad 
  cut 
  shows 
  18 
  

   feet 
  of 
  light 
  yellow 
  to 
  white 
  strongly 
  cross-bedded 
  sands 
  with
