  the

  The

  uplifted 
  marine

  is 
  extended 
  southward 
  

   across

  In 
  Vermont 
  

   "the 
  initial 
  or 
  summit 
  water-plane 
  now 
  lies 
  between 
  400 
  and 
  800 
  

   feet 
  above 
  tide." 
  The

  of 
  the

  invasion 
  to

   races 
  in

  Valley 
  and 
  to 
  the 
  ancient 
  glacial 
  lakes 
  of 
  

   central

  is 
  also

  the
