  J. 
  Barrell 
  — 
  The 
  Piedmont 
  Terraces 
  

  

  ford 
  and 
  Norwalk 
  quadrangles. 
  The 
  stair-like 
  character 
  

   of 
  these 
  benches 
  is 
  evident. 
  These 
  benches 
  are 
  not 
  so 
  

   strongly 
  developed 
  as 
  the 
  older 
  ones 
  ; 
  in 
  fact 
  the 
  Pitcher 
  

   Mountain 
  terrace 
  (280-320 
  feet) 
  is 
  entirely 
  re-entrant 
  in 
  

   character 
  in 
  this 
  area 
  and 
  the 
  New 
  Canaan 
  terrace 
  (340- 
  

   380 
  feet) 
  also 
  shows 
  this 
  feature. 
  The 
  elongated 
  flat- 
  

   topped 
  form 
  of 
  many 
  of 
  the 
  hills 
  is 
  a 
  characteristic 
  

   feature 
  of 
  the 
  topography 
  of 
  southern 
  Connecticut 
  the 
  

   significance 
  of 
  which, 
  from 
  the 
  point 
  of 
  view 
  of 
  the 
  

   marine 
  origin 
  of 
  the 
  terraces, 
  is 
  referred 
  to 
  by 
  Professor 
  

   Barrell 
  in 
  later 
  sections 
  of 
  the 
  article. 
  The 
  relative 
  

   steepness 
  of 
  the 
  slopes 
  which 
  connect 
  the 
  successive 
  level 
  

   benches 
  should 
  be 
  noted.

   (700-740

  Prospect

  by 
  8% 
  miles 
  in 
  extent 
  on 
  the 
  

   Derby

  New

  quadrangles. 
  The 
  integration 
  of 
  

   elongated 
  flat-topped 
  hills 
  into 
  an 
  even 
  sky-line 
  is 
  well 
  

   shown 
  and 
  also 
  the 
  relative 
  steepness 
  of 
  the 
  slope 
  join- 
  

   ing 
  the 
  two 
  levels. 
  As 
  will 
  appear, 
  this 
  latter 
  feature 
  is 
  

   taken 
  to 
  indicate 
  an 
  old 
  shore-line. 
  

  

  Figure

  shows

  parts 
  of 
  the 
  Litchfield 
  

   (1,100-1,140 
  feet) 
  and 
  Goshen 
  (1,340-1,380

  terraces 
  

   projected

  miles

  on 
  the 
  

   New 
  Milford

  Waterbury 
  quadrangles. 
  These 
  ter- 
  

   races 
  are 
  older 
  than 
  those 
  shown 
  on 
  the 
  preceding 
  pro- 
  

   files 
  and 
  the 
  hilltops 
  do 
  not 
  give 
  so 
  continuously 
  a 
  level 
  

   sky-line 
  although 
  they 
  are 
  quite 
  accordant 
  in 
  elevation.
