  the

  sands 
  come 
  to 
  an

  the

  situated 
  some 
  where 
  north 
  of 
  the

   but 
  does 
  not 
  specify 
  exactly 
  where. 
  The 
  mud-lumps 
  are 
  also 
  

   intimately 
  connected 
  with 
  the 
  subterranean 
  channels

  The 
  theory 
  of 
  the 
  tide 
  and 
  current 
  origin 
  was 
  advanced 
  by 
  

   Montaigu 
  in 
  1875. 
  He 
  supposed 
  that 
  in 
  the 
  eternal 
  conflict 
  

   between 
  the 
  river 
  and 
  the 
  ocean 
  currents, 
  great 
  pressure 
  was 
  at 
  

   times 
  exerted 
  on 
  the 
  beds 
  near 
  the 
  mouth 
  of 
  the 
  Mississippi, 
  

   which 
  occasionally 
  resulted 
  in 
  the 
  formation 
  of 
  mud-lumps.

  Of 
  these 
  theories 
  the 
  first 
  seems 
  to 
  be 
  best 
  supported 
  by 
  the 
  

   facts 
  at 
  hand 
  at 
  present.

  one 
  of 
  

   the 
  first 
  sites 
  of 
  salt 
  making 
  in 
  Louisiana. 
  This 
  locality 
  more 
  

   nearly 
  agrees 
  with 
  the 
  descriptions 
  of 
  the 
  position 
  of 
  the 
  salt 
  

   pits 
  which 
  Daniel 
  Coxe§ 
  described 
  in 
  1726, 
  from 
  which 
  the 
  

   " 
  Natchitock" 
  Indians 
  made 
  salt

  which
