  Aldrich,

  studied

   correct

  erroneous

  the

  Johnson 
  

   in

  He 
  states 
  among 
  

   other 
  things 
  that 
  there 
  was 
  a 
  period 
  when 
  the 
  Mississippi 
  

   embouched 
  at 
  Manchac. 
  The 
  Pontchartrain 
  claj^s 
  were 
  then 
  

   deposited. 
  These 
  extend 
  up 
  to 
  the

  The 
  Proceedings

  Museum, 
  

   vol. 
  ii,t 
  contains 
  a 
  note 
  by 
  Knowlton 
  describing 
  two 
  species 
  of 
  

   fossil 
  wood 
  from 
  Rapides 
  parish, 
  La. 
  They 
  were 
  collected 
  by 
  

   L. 
  C. 
  Johnson 
  in 
  1886. 
  Johnson 
  called 
  them 
  Pliocene 
  ; 
  McGee 
  

   says 
  they 
  are 
  of 
  Grand 
  Gulf 
  age 
  ; 
  Knowlton 
  thinks 
  the 
  age 
  very 
  

   uncertain. 
  They 
  are 
  Palms 
  called 
  Palmoxylon 
  quenstedti 
  and 
  P. 
  

   celhdosiim.

  pre- 
  

   pared 
  for 
  publication 
  some 
  of 
  Lesquereux's 
  species 
  from 
  Camp- 
  

   bell's

  Cross
