   Dear 
  Sir 
  : 
  I 
  transmit 
  with 
  this 
  a 
  report 
  upon 
  the 
  collection 
  of 
  

   fossil 
  plants 
  from 
  the 
  vicinity 
  of 
  Shreveport, 
  La., 
  which 
  you 
  

   sent 
  to 
  me 
  for 
  examination 
  some 
  months 
  since. 
  The 
  collection 
  

   numbers 
  about 
  175 
  specimens, 
  the 
  majority 
  of 
  which 
  are 
  beauti- 
  

   fully 
  preserved. 
  The 
  larger 
  number, 
  and 
  best 
  specimens, 
  are 
  in 
  

   a 
  fine 
  reddish 
  sandstone 
  *; 
  a 
  few 
  are 
  in 
  gray 
  sandstone 
  f 
  and 
  the 
  

   remainder 
  in 
  clay 
  J 
  or 
  cla}^ 
  concretions 
  || 
  . 
  

  

  About 
  50 
  species 
  are 
  represented. 
  Of 
  these 
  I 
  have 
  been 
  able 
  

   to 
  identify 
  30 
  either 
  positivelj^ 
  or 
  provisionally. 
  Six 
  others 
  I 
  

   have 
  described 
  as 
  new 
  species. 
  

  

  They 
  are 
  all 
  dicotyledonous 
  angiosperms, 
  with 
  the 
  exception 
  

   of 
  two 
  monocotyledons 
  and 
  one 
  fern, 
  and 
  they 
  indicate 
  a 
  Lower 
  

   Tertiary 
  horizon. 
  

  

  Very 
  truly 
  yours,
