  sea 
  had 
  had 
  time 
  to 
  reach 
  the 
  interior 
  region. 
  If 
  the 
  

   movement 
  of 
  uplift 
  were 
  200 
  feet 
  the 
  steepening 
  of 
  the 
  

   river 
  grade 
  during 
  downward 
  and 
  headward 
  cutting 
  

   would 
  cause, 
  at 
  a 
  certain 
  distance 
  inland, 
  the 
  new 
  grade 
  to 
  

   be 
  only 
  100 
  feet 
  below 
  the 
  old, 
  and 
  near 
  the 
  headwaters 
  

   the 
  influence 
  of 
  the 
  new 
  movement 
  would 
  completely 
  dis- 
  

   appear. 
  Thus 
  the 
  stages 
  of 
  crustal 
  movement 
  are 
  undif- 
  

   ferentiated 
  and 
  become 
  additive 
  in 
  a 
  continental 
  interior. 
  

   Phases 
  of 
  depression 
  of 
  the 
  crust 
  may 
  pass 
  without 
  

   record 
  in 
  that 
  region 
  whereas 
  on 
  the 
  seaward 
  margin 
  

   embayment 
  gives 
  a 
  sinuous 
  shore 
  and 
  sedimentation 
  

   takes 
  place 
  below 
  the 
  new 
  baselevel. 
  The 
  outer 
  slopes 
  of 
  

   the 
  continent, 
  therefore, 
  are 
  much 
  better 
  adapted 
  than 
  

   the 
  interior 
  for 
  a 
  study 
  of 
  detailed 
  changes 
  in 
  baselevel. 
  

   In 
  this 
  section 
  attention 
  has 
  been 
  called 
  to 
  the 
  indica- 
  

   tions 
  of 
  complexity 
  in 
  the 
  physiographic 
  history 
  of 
  the 
  

   Connecticut 
  upland. 
  The 
  detailed 
  analysis 
  of 
  the 
  nu- 
  

   merous 
  baselevels 
  which 
  have 
  left 
  a 
  record 
  will 
  be 
  post- 
  

   poned, 
  however, 
  until

  bearing 
  upon 
  their 
  interpretation.

  The 
  step-like 
  character 
  of 
  the 
  profile 
  of 
  the 
  western 
  

   upland, 
  referred 
  to 
  in 
  the 
  preceding 
  section 
  by 
  Professor 
  

   Barrell, 
  is 
  best 
  seen 
  in 
  pi. 
  V 
  which 
  shows 
  the 
  entire 
  series 
  

   of 
  terraces. 
  12 
  It 
  is 
  also 
  seen 
  in 
  the 
  following 
  projected 
  

   profiles 
  which 
  have 
  been 
  selected 
  from 
  a 
  much 
  larger 
  

   number 
  drawn 
  by 
  Professor 
  Barrell. 
  Most 
  of 
  them 
  

   show 
  the 
  topography 
  of 
  localities 
  where 
  the 
  "steps" 
  are 
  

   well 
  marked. 
  It 
  should 
  be 
  kept 
  in 
  mind 
  that 
  the 
  vertical 
  

   scale 
  of 
  all 
  the 
  profiles 
  is 
  greatly 
  exaggerated, 
  i. 
  e., 
  is 
  

   twenty-six 
  times 
  the 
  horizontal. 
  It 
  should 
  also 
  be 
  re- 
  

   membered 
  that 
  all 
  the 
  terraces, 
  however 
  perfect 
  may 
  

   have 
  been 
  their 
  initial 
  development, 
  have 
  been 
  dissected 
  

   by 
  later 
  subaerial 
  erosion 
  so 
  that 
  they 
  are 
  to 
  be 
  recog- 
  

   nized 
  at 
  the 
  present 
  time 
  only 
  from 
  their 
  remnants. 
  If 
  

   the 
  planation 
  were 
  complete 
  in 
  all 
  cases, 
  it 
  would 
  be 
  ex- 
  

   pected 
  that 
  the 
  remnants 
  of 
  the 
  younger 
  terraces 
  would 
  

   integrate 
  into 
  a 
  more 
  even 
  and 
  continuous 
  sky-line 
  than 
  

   the 
  older 
  ones.
