  continental 
  ones. 
  The 
  conditions 
  in 
  Baffin 
  Land 
  are 
  less 
  

   certain, 
  but 
  even 
  here 
  it 
  seems 
  natural 
  to 
  assume 
  for 
  

   Lower 
  Devonian 
  time 
  a 
  water-way 
  connecting 
  the 
  Elles- 
  

   mereland 
  region 
  with 
  the 
  eastern 
  part 
  of 
  the 
  continent 
  

   of 
  North 
  America. 
  The 
  Helderbergian 
  faunas 
  of 
  the 
  

   two 
  districts 
  are 
  indeed 
  so 
  similar 
  that 
  an 
  open 
  oceanic 
  

   connection 
  must 
  have 
  existed.

  The 
  very 
  large 
  North 
  Atlantic 
  continent, 
  including 
  

   North 
  America 
  (=Eria 
  of 
  Dawson), 
  is 
  the 
  dominating 
  

   feature 
  of 
  this 
  time, 
  and 
  a 
  mighty 
  faulting 
  still 
  continues 
  

   which 
  is 
  most 
  distinct 
  in 
  Bear 
  Island 
  and 
  Spitzbergen. 
  

   In 
  the 
  latter 
  district, 
  the 
  marine 
  Carboniferous 
  in 
  some 
  

   places 
  rests 
  on 
  the 
  continental 
  Lower 
  Carboniferous, 
  

   which 
  may 
  be 
  more 
  than 
  1000 
  m. 
  in 
  thickness 
  ; 
  in 
  other 
  

   places 
  this 
  division 
  has 
  been 
  totally 
  denuded 
  and 
  the 
  

   marine 
  beds 
  then 
  lie 
  on 
  the 
  Devonian.
