  than 
  the 
  surrounding 
  land 
  but 
  each 
  little 
  bayou 
  has 
  done 
  like- 
  

   wise. 
  Thus 
  a 
  basin 
  is 
  formed 
  in 
  the 
  inter-bayou 
  space. 
  The 
  

   old 
  Dooley 
  bayou 
  swamp 
  and 
  the 
  now 
  filled 
  Simpson's 
  lake 
  

   probably 
  occupied 
  such 
  depressions. 
  Old 
  Swan 
  lake 
  just 
  above 
  

   Shreveport, 
  between 
  Twelve 
  Mile 
  bayou 
  and 
  the 
  river 
  was 
  of 
  

   this 
  type. 
  

  

  Raft 
  lakes. 
  — 
  The 
  origin 
  of 
  lakes 
  of 
  this 
  type 
  has 
  already 
  been 
  

   discussed 
  under 
  the 
  headings 
  "Growth 
  of 
  the 
  Raft" 
  and 
  

   " 
  Changes 
  due 
  to 
  the 
  Formation 
  of 
  the 
  Raft 
  " 
  and 
  Ferry, 
  Sodo 
  

   and 
  Cross 
  lakes 
  were 
  referred 
  to 
  this 
  type. 
  It 
  remains, 
  how- 
  

   ever, 
  to 
  call 
  attention 
  to 
  the 
  similarity 
  in 
  position 
  and 
  origin 
  of 
  

   these 
  lakes 
  to 
  the 
  other 
  large 
  lakes 
  of 
  Red 
  River 
  valley 
  ; 
  to 
  give 
  

   the 
  traditions 
  and 
  historical 
  data 
  we 
  possess 
  regarding 
  them 
  and 
  

   to 
  give 
  some 
  other 
  theories 
  which 
  have 
  been 
  advanced 
  to 
  account 
  

   for 
  them. 
  

  

  A 
  reference 
  to 
  a 
  good 
  map 
  of 
  the 
  State 
  of 
  Louisiana 
  will 
  show 
  

   lakes 
  which 
  are 
  the 
  exact 
  counterpart 
  of 
  Cross 
  lake 
  and 
  Sodo 
  

   lake 
  all 
  along 
  the 
  river 
  valley 
  below 
  the 
  Arkansas 
  line. 
  Those 
  

   which 
  have 
  been 
  clearly 
  formed 
  by 
  the 
  drowning 
  of 
  old 
  stream 
  

   valleys 
  and 
  which 
  belong 
  to 
  the 
  same 
  type 
  as 
  Cross 
  and 
  Ferry 
  

   lakes 
  are 
  : 
  Lake 
  Bodcau, 
  Wallace 
  lake, 
  Lake 
  Bistineau, 
  Black 
  

   lake, 
  Saline 
  lake, 
  Spanish 
  lake. 
  Lake 
  Terre 
  Noir, 
  Lake 
  Nan- 
  

   taches 
  and 
  Lake 
  latt. 
  There 
  are 
  also 
  several 
  which 
  have 
  been 
  

   formed 
  in 
  bottom 
  basins 
  like 
  Sodo 
  lake. 
  The 
  two 
  most 
  pro- 
  

   nounced 
  of 
  these 
  are. 
  Lake 
  Cannisnia 
  and 
  the 
  lower 
  part 
  of 
  

   Bayou 
  Pierre 
  lake. 
  They 
  are 
  so 
  alike 
  in 
  their 
  general 
  features 
  

   and 
  occupy 
  such 
  analogous 
  positions 
  that 
  any 
  theory 
  accounting 
  

   for 
  the 
  origin 
  of 
  one 
  must, 
  in 
  general, 
  cover 
  the 
  origin 
  of 
  all. 
  

  

  Of 
  the 
  recent 
  origin 
  of 
  the 
  lakes 
  in 
  the 
  upper 
  part 
  of 
  the 
  val- 
  

   ley 
  there 
  can 
  be 
  little 
  question. 
  A 
  number 
  of 
  planters 
  of 
  Red 
  

   river 
  bottoms 
  have 
  repeated 
  to 
  me 
  the 
  old 
  Caddo 
  Indian 
  tradition 
  

   that 
  about 
  one 
  hundred 
  and 
  fifty 
  years 
  ago 
  the 
  land 
  now 
  occu- 
  

   pied 
  by 
  Sodo 
  lake 
  was 
  an 
  oak 
  ridge, 
  that 
  all 
  the 
  water 
  flowed 
  in 
  

   a 
  narrow 
  cypress-fringed 
  bayou 
  in 
  the 
  center 
  and 
  that 
  the 
  filling 
  

   of 
  the 
  valley 
  was 
  sudden, 
  as 
  if 
  by 
  an 
  earthquake. 
  

  

  Collins 
  evidently 
  heard 
  much 
  the 
  same 
  story, 
  which 
  he 
  states 
  

   in 
  this 
  way: 
  " 
  Mr. 
  Josey, 
  living 
  at 
  Swanson's 
  landing, 
  who 
  is 
  

   probably 
  the 
  most 
  intelligent 
  man 
  in 
  the 
  vicinity, 
  thinks 
  there
