  of 
  Grand 
  Gulf 
  is 
  in 
  the 
  Kisatchie 
  hills. 
  The 
  road 
  from 
  Lees- 
  

   ville 
  to 
  Provencal 
  passes 
  through 
  a 
  strip 
  of 
  black 
  prairie 
  land 
  

   about 
  four 
  miles 
  from 
  Iveesville 
  called 
  Anacaco 
  prairie. 
  Cal- 
  

   careous 
  concretions 
  are 
  scattered 
  over 
  the 
  ground 
  in 
  large 
  

   numbers 
  but 
  no 
  fossils 
  were 
  seen. 
  Another 
  small 
  calcareous 
  

   prairie 
  of 
  about 
  four 
  acres 
  in 
  extent 
  occurs 
  north 
  of 
  Hardshell. 
  

   In 
  about 
  Sec. 
  5, 
  4 
  N., 
  8 
  W., 
  a 
  light 
  colored 
  ledge 
  crops 
  out 
  in 
  the 
  

   road. 
  Between 
  Kisatchie 
  bayou 
  and 
  Bellewood, 
  sandstone 
  

   becomes 
  quite 
  common, 
  and 
  calcareous 
  prairies 
  are 
  still 
  to 
  be 
  

   found. 
  The 
  northern 
  limit 
  of 
  the 
  sandstone 
  is 
  about 
  Bellewood. 
  

   On 
  the 
  divide 
  between 
  the 
  headwaters 
  of 
  Kisatchie 
  and 
  Toro 
  

   bayous 
  the 
  Grand 
  Gulf 
  probably 
  extends 
  well 
  to 
  the 
  north, 
  and 
  

   it 
  may 
  be 
  that 
  the 
  "Bad 
  Hill* 
  " 
  mentioned 
  by 
  Hopkins 
  as 
  seven 
  

   miles 
  south 
  of 
  Many 
  is 
  in 
  this 
  region. 
  If 
  Bad 
  Hill 
  is 
  seven 
  miles 
  

   due 
  south 
  of 
  Many 
  it 
  is 
  Lower 
  Claiborne, 
  for 
  numerous 
  fossils 
  are 
  

   found 
  in 
  this 
  region 
  and 
  the 
  distance 
  to 
  the 
  first 
  Grand 
  Gulf 
  

   outcrop 
  due 
  south 
  of 
  Many 
  is 
  about 
  18 
  miles. 
  The 
  writers 
  have 
  

   in 
  no 
  place 
  seen 
  the 
  Grand 
  Gulf 
  north 
  or 
  west 
  of 
  Bayou 
  Toro. 
  

   The 
  large 
  quarries 
  in 
  4 
  N., 
  11 
  W., 
  which 
  have 
  been 
  opened 
  to 
  

   obtain 
  stone 
  for 
  crib 
  work 
  at 
  Sabine 
  Pass, 
  Texas 
  afford 
  good 
  

   opportunities 
  for 
  examining 
  the 
  formation 
  in 
  this 
  region. 
  The 
  

   line 
  of 
  parting 
  between 
  the 
  Grand 
  Gulf 
  and 
  the 
  Jackson 
  lies 
  

   from 
  a 
  mile 
  to 
  two 
  miles 
  east 
  of 
  Bayou 
  Toro 
  from 
  the 
  railroad 
  

   bridge 
  to 
  its 
  mouth, 
  where 
  the 
  Grand 
  Gulf 
  crosses 
  the 
  Sabine 
  

   river 
  into 
  Texas. 
  In 
  Sec. 
  9 
  and 
  17 
  3 
  N., 
  11 
  W., 
  large 
  quantities 
  

   of 
  stone 
  are 
  strewn 
  over 
  the 
  hillsides. 
  Great 
  masses 
  separated 
  

   by 
  erosion 
  often 
  occupy 
  outlying 
  hills 
  and 
  are 
  locally 
  supposed 
  

   to 
  be 
  of 
  volcanic 
  origin. 
  Of 
  the 
  southern 
  boundary 
  of 
  the 
  

   formation 
  Hilgard 
  says 
  : 
  " 
  The 
  line 
  originally 
  laid 
  down 
  by 
  me, 
  

   and 
  adopted 
  by 
  Prof. 
  Hopkins, 
  in 
  his 
  Geological 
  Map 
  of 
  the 
  State, 
  

   is 
  based 
  upon 
  the 
  connection 
  of 
  the 
  outcrops 
  near 
  Chicotville, 
  

   then 
  near 
  the 
  mouth 
  of 
  Mill 
  creek 
  into 
  Calcasieu 
  river 
  and 
  the 
  

   point 
  on 
  the 
  Sabine 
  (Salem) 
  given 
  as 
  the 
  limit 
  between 
  the 
  

   Quaternary 
  and 
  Tertiary, 
  by 
  Prof. 
  Buckley 
  of 
  Texas.
