  Sparta. 
  — 
  North 
  of 
  King's 
  salt 
  works 
  on 
  the 
  Coushatta-Sparta. 
  

   road 
  the 
  hills 
  rise 
  very 
  abruptly 
  120 
  feet. 
  The 
  material 
  seems 
  

   to 
  be 
  almost 
  entirely 
  a 
  light 
  colored, 
  rather 
  fine 
  sand. 
  Rapid 
  

   erosion 
  gives 
  rise 
  to 
  some 
  very 
  interesting 
  topographic 
  forms 
  ; 
  

   great, 
  perfectly 
  shaped 
  ampitheaters 
  are 
  common 
  near 
  the 
  heads 
  

   of 
  the 
  valleys. 
  On 
  the 
  whole 
  it 
  is 
  a 
  topography 
  without 
  sharp 
  

   angles. 
  In 
  places 
  natural 
  land-locked 
  ponds 
  were 
  seen, 
  looking 
  

   like 
  great 
  sink-holes. 
  

  

  About 
  six 
  miles 
  from 
  Sparta 
  long-leaf 
  pine 
  takes 
  the 
  place 
  of 
  

   the 
  short-leaf 
  and 
  continues 
  to 
  within 
  a 
  mile 
  of 
  the 
  old 
  town. 
  

   At 
  Sparta 
  nothing 
  is 
  to 
  be 
  seen 
  but 
  fine, 
  light-colored 
  sand 
  with 
  

   coarse 
  iron 
  sandstone 
  boulders. 
  There 
  seems 
  to 
  be 
  no 
  good 
  

   reason 
  for 
  separating 
  this 
  sand 
  from 
  the 
  adjacent 
  Claiborne 
  beds. 
  

  

  Liberty 
  Hill. 
  — 
  Nearly 
  all 
  the 
  hills 
  in 
  the 
  vicinity 
  of 
  Liberty 
  

   hill 
  are 
  covered 
  with 
  ferruginous 
  concretions 
  filled 
  with 
  casts 
  of 
  

   Lower 
  Claiborne 
  fossils. 
  The 
  best 
  locality 
  seen 
  was 
  above, 
  i 
  ^ 
  

   miles 
  northeast 
  of 
  the 
  village 
  on 
  the 
  Ruston 
  road. 
  Near 
  a 
  

   graveyard, 
  north 
  of 
  the 
  stores, 
  fossiliferous 
  iron 
  concretions 
  

   were 
  seen 
  capping 
  the 
  hill. 
  They 
  were 
  here 
  underlaid 
  by 
  beds 
  

   of 
  coarse 
  iron 
  sandstone 
  and 
  by 
  the 
  gray 
  Arcadia 
  clays 
  of 
  

   Lerch. 
  This 
  would 
  seem 
  to 
  show 
  that 
  the 
  Arcadia 
  clays 
  are 
  

   merely 
  a 
  subordinate 
  bed 
  of 
  the 
  Lower 
  Claiborne.* 
  

  

  The 
  fossiliferous 
  Lower 
  Claiborne 
  material 
  continues 
  for 
  about 
  

   10 
  miles 
  north 
  of 
  Liberty 
  hill 
  on 
  the 
  Arcadia 
  road.
