  The 
  most 
  important 
  and 
  continuous 
  is 
  the 
  Black 
  lake 
  bayou 
  and 
  

   Dauchite 
  bayou 
  deposit. 
  Between 
  Shongaloo 
  and 
  Sykes 
  ferry 
  

   the 
  gravel 
  is 
  quite 
  abundant. 
  At 
  old 
  Haynesville 
  great 
  quanti- 
  

   ties 
  crop 
  out 
  in 
  the 
  hillsides. 
  The 
  territory 
  between 
  the 
  two 
  

   localities 
  was 
  not 
  passed 
  over, 
  but 
  it 
  seems 
  probable 
  that 
  the 
  two 
  

   deposits 
  are 
  connected. 
  Going 
  south 
  the 
  gravel 
  ridge 
  narrows. 
  

   No 
  northern 
  gravels 
  are 
  found 
  on 
  the 
  red 
  lands 
  in 
  T.

  At 
  Minden 
  gravel 
  was 
  seen 
  from 
  about 
  half 
  a 
  mile 
  west 
  

   of 
  the 
  Dauchite 
  bridge 
  to 
  a 
  little 
  beyond 
  Crow's 
  bayou 
  on 
  the 
  

   Homer 
  road. 
  On 
  the 
  large 
  hill 
  between 
  Minden 
  and 
  the 
  bridge 
  

   it 
  is 
  common 
  to 
  a 
  height 
  of 
  65 
  feet 
  above 
  the 
  bottoms. 
  Between 
  

   Minden 
  and 
  Sibley 
  nearly 
  all 
  the 
  hillsides 
  show 
  gravel. 
  

   In 
  the 
  railroad 
  cut 
  at 
  the 
  latter 
  place 
  17 
  feet 
  of 
  gravel 
  and 
  cross- 
  

   bedded 
  sands 
  are 
  exposed. 
  Pebbles 
  as 
  large 
  as 
  a 
  man's 
  fist 
  are 
  

   seen 
  here. 
  This 
  gravel 
  was 
  found 
  as 
  far 
  east 
  as 
  Black 
  lake 
  

   bayou. 
  The 
  country 
  between 
  Sibley 
  and 
  King's 
  salt 
  works 
  was 
  

   not 
  personally 
  examined, 
  but 
  we 
  are 
  credibly 
  informed 
  that 
  

   gravel 
  is 
  common. 
  Pebble 
  conglomerate 
  is 
  often 
  seen 
  on 
  the 
  

   hills 
  around 
  King's 
  salt 
  works, 
  and 
  on 
  the 
  Sparta-Campti 
  road 
  

   between 
  Castor 
  and 
  Toby 
  creeks. 
  Just 
  south 
  of 
  this 
  exposure 
  is 
  

   a 
  very 
  fossiliferous 
  Lower 
  Claiborne 
  prairie 
  and 
  no 
  more 
  gravel 
  

   occurs 
  between 
  here 
  and 
  Lake 
  village. 
  On 
  the 
  west 
  side 
  of 
  

   Black 
  lake 
  bayou, 
  between 
  Lake 
  village 
  and 
  Coushatta, 
  the 
  

   gravel 
  band 
  is 
  three 
  or 
  four 
  miles 
  wide. 
  At 
  Black 
  lake 
  the 
  

   gravel 
  again 
  occurs 
  on 
  the 
  eastern 
  side 
  of 
  the 
  bayou. 
  Here 
  it 
  is 
  

   in 
  close 
  proximity 
  to 
  fossiliferous 
  Lower 
  Claiborne 
  prairies. 
  The 
  

   gravel 
  occurs 
  on 
  the 
  hillsides 
  in 
  Sec. 
  4, 
  11 
  N., 
  6 
  W. 
  The 
  very 
  

   crest 
  of 
  the 
  hill 
  is 
  covered 
  with 
  Osterea 
  falcifo7'-mis 
  and 
  O. 
  

   Johnsoni. 
  

  

  At 
  Grand 
  Kcore 
  ten 
  feet 
  of 
  white 
  and 
  yellow 
  chert 
  pebbles 
  acd 
  

   sand 
  cap 
  the 
  bluff. 
  They 
  extend 
  scarcely 
  an 
  eighth 
  of 
  a 
  mile 
  

   from 
  the 
  river. 
  

  

  Sahit 
  Maurice 
  and 
  Montgomery. 
  — 
  At 
  Saint 
  Maurice 
  large 
  

   quartz 
  boulders 
  are 
  found 
  on 
  the 
  hillsides 
  twenty 
  to 
  forty 
  feet 
  

   above 
  the 
  fossiliferous 
  Lower 
  Claiborne 
  in 
  the 
  l)ed 
  of 
  Saline 
  

   bayou. 
  

  

  From 
  3 
  to 
  4 
  miles 
  northeast 
  of 
  Montgomery, 
  on 
  the 
  east 
  side 
  

   of 
  Bayou 
  Nantaches, 
  there 
  are 
  quite 
  prominent 
  escarpments 
  of
