  Drake.^ 
  — 
  In 
  a 
  volume 
  entitled 
  the 
  " 
  Principal 
  Diseases 
  of 
  the 
  

   Interior 
  Valley 
  of 
  North 
  America," 
  Dr. 
  Daniel 
  Drake 
  succeeded 
  

   in 
  weaving 
  in 
  many 
  facts 
  and 
  statements 
  of 
  geological 
  interest. 
  

   His 
  description 
  of 
  the 
  mud 
  lumps 
  (pp. 
  91-94) 
  is 
  particularly 
  

   good 
  and 
  deserves 
  attention 
  because 
  he 
  advances 
  the 
  gas 
  theory 
  

   for 
  the 
  formation 
  of 
  these 
  objects. 
  He 
  gives 
  (p. 
  71) 
  a 
  well 
  sec- 
  

   tion 
  on 
  L,ake 
  Pontchartrain 
  and 
  the 
  section 
  exposed 
  in 
  the 
  gas 
  

   tank 
  excavation 
  at 
  New 
  Orleans. 
  On 
  page 
  161 
  he 
  states 
  that 
  

   the 
  geological 
  formation 
  about 
  Fort 
  Jessup 
  is 
  Tertiary.

  — 
  In 
  1853 
  appeared 
  a 
  somewhat 
  extensive 
  work 
  on 
  the 
  

   lower 
  Mississippi 
  by 
  Charles 
  Ellet, 
  C. 
  E.f 
  This 
  book 
  is 
  severely 
  

   criticised 
  by 
  Jones 
  in 
  the 
  Journal 
  of 
  the 
  Franklin 
  Institute, 
  vol. 
  

   26,

  Thomassy.\ 
  — 
  In 
  i860, 
  Reymond 
  Thomassy 
  published 
  his 
  

   " 
  Geologic 
  Pratique 
  de 
  la 
  Louisiane," 
  both 
  in 
  this 
  country 
  and 
  

   in 
  France 
  (Paris). 
  

  

  Whatever 
  may 
  be 
  said 
  of 
  the 
  use 
  of 
  the 
  word 
  " 
  pratique 
  " 
  in 
  

   his 
  title, 
  Thomassy 
  had 
  access 
  to 
  and 
  used 
  to 
  good 
  advantage 
  the 
  

   earlier 
  rare 
  contributions 
  to 
  the 
  cartography 
  of 
  Louisiana. 
  His 
  

   geology, 
  was 
  in 
  the 
  main 
  limited 
  to 
  a 
  discussion 
  of 
  the 
  role 
  the 
  

   Mississippi 
  river 
  has 
  played 
  in 
  the 
  formation 
  of 
  the 
  so-called 
  

   delta 
  region 
  of 
  the 
  State. 
  Particularly 
  was 
  he 
  impressed 
  with 
  

   the 
  multifold 
  manifestations 
  of 
  water 
  absorption 
  all 
  along 
  the 
  

   Mississippi 
  and 
  its 
  consequent 
  diminution 
  in 
  volume 
  gulf-wards, 
  

   and 
  the 
  appearance 
  of 
  lateral 
  springs, 
  lakes 
  and 
  terminal 
  mud- 
  

   lump 
  volcanoes, 
  all 
  having 
  their 
  origin 
  in 
  the 
  porosity 
  of 
  the 
  

   grounds 
  of 
  southern 
  Louisiana 
  and 
  the 
  consequent 
  subter- 
  

   ranean 
  flow 
  of 
  large 
  quantities 
  of 
  water,
