  Correlation 
  of 
  the 
  

  

  problem 
  which 
  has 
  not 
  been 
  satisfactorily 
  solved 
  up 
  to 
  the 
  

   present. 
  In 
  this 
  paper 
  an 
  attempt 
  is 
  made 
  to 
  correlate 
  the 
  

   Mississippian 
  formations 
  in 
  these 
  two 
  areas, 
  preliminary 
  to 
  a 
  

   discussion 
  of 
  the 
  Devonian. 
  Also 
  an 
  effort 
  is 
  made 
  to 
  defend 
  

   the 
  proposition 
  that 
  the 
  Berea 
  is 
  the 
  basal 
  formation 
  of 
  the 
  

   Mississippian.
