  Sabinetoivn. 
  — 
  A 
  short 
  distance 
  below 
  the 
  ferry 
  on 
  the 
  Texas 
  

   side 
  of 
  the 
  Sabine 
  there 
  is 
  a 
  most 
  interesting 
  section, 
  not 
  only 
  

   for 
  the 
  light 
  that 
  it 
  sheds 
  on 
  the 
  geology 
  of 
  west 
  Eouisiana, 
  but 
  

   also 
  for 
  the 
  various 
  horizons 
  to 
  which 
  its 
  beds 
  have 
  been 
  

   referred. 
  (See 
  under 
  Hilgard, 
  Historic 
  review.) 
  

  

  Putting 
  aside 
  the 
  past, 
  we 
  proceed 
  at 
  once 
  to 
  a 
  detailed 
  

   description 
  of 
  this 
  classic 
  locality. 
  

  

  This 
  bluff 
  is 
  from 
  115 
  to 
  120 
  feet 
  high, 
  counting 
  from 
  the 
  

   surface 
  of 
  the 
  river 
  at 
  a 
  medium 
  stage 
  of 
  water. 
  It 
  is 
  located 
  on 
  

   a 
  bend 
  of 
  the 
  river 
  where 
  the 
  latter 
  pursues 
  a 
  nearly 
  east-west 
  

   direction. 
  Though 
  the 
  dip 
  is 
  locally 
  very 
  considerable 
  here 
  as 
  

   shown 
  in 
  little 
  side 
  gorges 
  often 
  5^ 
  south, 
  it 
  appears 
  slight 
  

   along 
  the 
  bluff 
  as 
  a 
  whole, 
  for 
  the 
  direction 
  of 
  the 
  latter 
  is 
  

   nearly 
  on 
  the 
  line 
  of 
  strike. 
  

  

  The 
  main 
  features 
  of 
  the 
  various 
  component 
  strata 
  are 
  as 
  follows 
  : 
  

  

  8. 
  Sands 
  and 
  ferruginous 
  conglomerates 
  9-16 
  ft. 
  

  

  7. 
  Ferruginous 
  sandstone 
  i 
  ft. 
  

  

  6. 
  Eignitic 
  clay 
  15 
  ft. 
  

  

  5. 
  Yellow 
  sand 
  25 
  ft. 
  

  

  4. 
  More 
  or 
  less 
  alternating 
  shaly 
  lignitic 
  clay 
  and 
  sand. 
  

   The 
  latter 
  weathering 
  yellowish 
  ; 
  the 
  shaly 
  clay 
  

  

  sometimes 
  light 
  brown 
  or 
  pinkish 
  40 
  ft. 
  

  

  3. 
  More 
  or 
  less 
  clayey 
  sand, 
  often 
  greenish 
  and 
  fossilifer- 
  

  

  ous 
  in 
  concretions 
  ; 
  with 
  a 
  hard 
  layer 
  above 
  15 
  ft. 
  

  

  2. 
  Fossiliferous 
  blue 
  sand 
  with 
  concretions 
  6 
  ft. 
  

  

  I. 
  Brittle, 
  shaly, 
  drab 
  clay 
  2 
  ft. 
  

  

  We 
  have 
  only 
  to 
  glance 
  at 
  the 
  fossils 
  to 
  be 
  impressed 
  with 
  the 
  

   almost 
  perfect 
  likeness 
  they 
  bear 
  to 
  the 
  Woods 
  bluff 
  beds 
  in 
  

   Alabama. 
  Some 
  have 
  already 
  been 
  figures 
  in 
  Bulletins 
  of 
  

   American 
  Paleontology 
  and 
  others 
  may 
  be 
  found 
  elsewhere 
  in 
  

   this 
  report. 
  (See 
  Paleontology 
  the 
  Eignite 
  stage.) 
  The 
  best 
  

   fossils 
  are 
  found 
  in 
  the 
  greenish 
  sandy 
  layer 
  at 
  the 
  west 
  end 
  of 
  

   bluff, 
  just 
  east 
  of 
  where 
  a 
  little 
  stream 
  empties 
  into 
  the 
  river. 
  

  

  Low' 
  s 
  creek. 
  — 
  One 
  and 
  one-half 
  mile 
  to 
  the 
  south 
  of 
  Sabine- 
  

   town 
  bluff 
  in 
  the 
  bed 
  of 
  Eow's 
  creek 
  at 
  the 
  ford, 
  Eower 
  Claiborne 
  

   fossils 
  are 
  found. 
  But 
  beneath 
  the 
  same 
  in 
  what 
  is 
  presumably 
  

   Eignitic 
  material, 
  a 
  vast 
  number 
  of 
  Pedens 
  cornuus 
  occur.
