  delta 
  flat, 
  the 
  valley 
  narrows 
  considerablj, 
  but 
  still 
  is 
  very 
  wide 
  in 
  

   comparison 
  with 
  the 
  small 
  stream 
  running 
  through 
  it. 
  

  

  Continuing 
  southward, 
  the 
  valley 
  slowly 
  rises, 
  the 
  morainal 
  hills 
  

   constantly 
  become 
  more 
  prominent, 
  and 
  are 
  here 
  and 
  there 
  inter- 
  

   cepted 
  by 
  kettle-holes 
  forming 
  small 
  lakes 
  and 
  swamps 
  in 
  the 
  wet 
  

   season. 
  

  

  A 
  cross-section 
  of 
  the 
  valley, 
  where 
  the 
  moraine 
  is 
  typically 
  

   developed, 
  presents 
  the 
  following 
  appearance 
  : 
  the 
  valley 
  is 
  half 
  

   a 
  mile 
  wide, 
  or 
  less, 
  the 
  highest 
  hills 
  on 
  either 
  side 
  being 
  rounded, 
  

   drumlinoid 
  hills 
  cut 
  out 
  of 
  the 
  country 
  rock, 
  and 
  by 
  stream 
  erosion, 
  

   and 
  as 
  a 
  general 
  thing 
  have 
  almost 
  no 
  drift 
  covering, 
  as 
  shown 
  by 
  

   their 
  being 
  uncultivated. 
  

  

  Just 
  within 
  these 
  bounding 
  hills, 
  and 
  perhaps 
  a 
  third 
  their 
  height, 
  

   are 
  the 
  typical 
  morainal 
  knolls, 
  most 
  of 
  which 
  are 
  of 
  stratified 
  

   material 
  — 
  at 
  least 
  in 
  part. 
  Near 
  Newfield 
  one 
  of 
  these 
  hills 
  con- 
  

   sists 
  of 
  a 
  tine 
  quality 
  of 
  blue 
  clay 
  with 
  but 
  little 
  iron 
  stain, 
  which 
  is 
  

   used 
  for 
  brick 
  making. 
  Much 
  sand 
  of 
  excellent 
  quality 
  is 
  visible 
  

   where 
  streams 
  have 
  cut 
  into 
  the 
  banks. 
  * 
  

  

  These 
  irregular 
  knolls 
  grade 
  down 
  in 
  size 
  quite 
  rapidly 
  toward 
  

   the 
  center 
  of 
  the 
  valley, 
  which 
  is 
  flat 
  for 
  a 
  considerable 
  distance 
  

   before 
  the 
  hills 
  rise 
  again 
  on 
  the 
  opposite 
  side. 
  

  

  Along 
  here 
  the 
  '^ 
  Inlet 
  " 
  is 
  but 
  a 
  small 
  brook, 
  and 
  it 
  is 
  an 
  excellent 
  

   example 
  of 
  an 
  overladen 
  stream. 
  To 
  suppose 
  that 
  it 
  had 
  cut 
  down 
  

   through 
  the 
  drift 
  and 
  so 
  formed 
  its 
  broad, 
  flat 
  valley 
  would 
  be 
  

   unwarranted. 
  The 
  amount 
  of 
  erosion 
  through 
  the 
  drift-tilled, 
  pre- 
  

   glacial 
  valleys 
  in 
  the 
  neighborhood, 
  by 
  streams 
  of 
  much 
  greater 
  

   volume 
  and 
  flowing 
  more 
  rapidly, 
  has 
  not 
  been 
  one 
  third 
  as 
  great 
  

   in 
  any 
  instance. 
  

  

  How, 
  then, 
  are 
  we 
  to 
  account 
  for 
  this 
  valley 
  ? 
  It 
  would 
  require 
  

   a 
  great 
  amount 
  of 
  study 
  over 
  the 
  whole 
  region 
  to 
  account 
  with 
  cer- 
  

   tainty 
  for 
  the 
  position 
  of 
  the 
  drift. 
  A 
  mere 
  reconnaissance 
  shows 
  

   it 
  to 
  be 
  a 
  preglacial 
  valley 
  choked 
  with 
  drift. 
  The 
  drift 
  is 
  higher 
  

   on 
  the 
  sides 
  than 
  in 
  the 
  center 
  — 
  this 
  may 
  be 
  due 
  to 
  a 
  greater 
  depth 
  

   of 
  deposit 
  along 
  the 
  sides, 
  (Figure 
  2, 
  a) 
  or 
  to 
  a 
  greater 
  depth 
  of 
  

   original 
  erosion 
  in 
  the 
  center 
  and 
  a 
  comparatively 
  uniform 
  deposi- 
  

   tion 
  of 
  drift, 
  (Figure 
  2, 
  b).
