  The 
  physiography 
  of 
  Connecticut 
  has 
  been 
  so 
  well 
  de- 
  

   scribed 
  by 
  Davis 
  10 
  that 
  it 
  will 
  only 
  be 
  necessary 
  to 
  record 
  

   here 
  certain 
  new 
  facts 
  which 
  have 
  been 
  determined 
  since 
  

   his 
  descriptions, 
  as 
  well 
  as 
  that 
  in 
  the 
  "Geology 
  of 
  Con- 
  

   necticut,' 
  ?11 
  were 
  published, 
  and 
  to 
  restate 
  certain 
  gen- 
  

   eral 
  features 
  bearing 
  on 
  the 
  problem 
  under 
  discussion. 
  

  

  The 
  upland 
  attains 
  its 
  greatest 
  altitude 
  in 
  the 
  extreme 
  

   northwestern 
  part 
  of 
  the 
  state 
  and 
  slopes 
  gently 
  down 
  

   toward 
  Long 
  Island 
  Sound, 
  the 
  slope 
  becoming 
  steeper 
  

   in 
  the 
  last 
  5 
  to 
  10 
  miles. 
  It 
  is 
  divided 
  into 
  two 
  parts 
  by 
  

   the 
  central 
  lowland 
  and 
  these 
  are 
  commonly 
  known 
  as 
  

   the 
  eastern 
  and 
  western 
  uplands. 
  The 
  upland 
  surface 
  

   has 
  had 
  a 
  physiographic 
  history 
  corresponding 
  in 
  gen- 
  

   eral 
  to 
  that 
  of 
  the 
  Piedmont 
  Plateau 
  of 
  the 
  Middle 
  and 
  

   South 
  Atlantic 
  States 
  and 
  to 
  the 
  Coastal 
  Plain, 
  although 
  

   the 
  later 
  record 
  is 
  left 
  in 
  different 
  form.

  submerged,

  the 
  waters 
  of 
  Long 
  Island 
  Sound 
  against 
  the 
  

   ancient 
  metamorphic 
  rocks.
