  It 
  would 
  be 
  tedious 
  and 
  unnecessary 
  to 
  enumerate 
  all 
  

   the

  these 
  deposits

  MARLS 
  OR 
  MINERAL 
  FERTILIZERS. 
  

  

  The 
  term 
  marl 
  is 
  often 
  very 
  vaguely 
  applied 
  by 
  dif- 
  

   ferent 
  writers 
  ; 
  and 
  the 
  names 
  variously 
  given 
  to 
  the 
  

   mineral 
  substances 
  sometimes 
  used 
  as 
  renovators 
  of 
  the 
  

   soil, 
  do 
  not 
  always 
  convey 
  a 
  clear 
  idea 
  of 
  their 
  distinctive 
  

   character 
  or 
  projDerties. 
  

  

  In 
  Europe, 
  a 
  non-calcareous 
  earth 
  is 
  used 
  as 
  clay- 
  

   marl; 
  and 
  slate-marl, 
  gypseous 
  marl, 
  bituminous 
  or 
  fetid 
  

   marl, 
  and 
  variegated 
  marl, 
  &c., 
  are 
  frequently 
  spoken 
  of; 
  

   the 
  latter, 
  a 
  marbled 
  earth 
  containing 
  sulphate 
  of 
  iron, 
  

   and 
  certainly 
  very 
  unfit 
  to 
  be 
  used 
  as 
  a 
  marl, 
  however 
  it 
  

   may 
  be 
  called.
