  SEARLES 
  T. 
  WOOD 
  ON 
  THE 
  NEWER 
  

  

  of 
  a 
  thin 
  bed 
  of 
  clay 
  near 
  the 
  

   north 
  end, 
  which 
  was 
  cut 
  off 
  

   by 
  that 
  shingle. 
  No 
  trace 
  of 
  

   the 
  gravel 
  c 
  I 
  found, 
  however, 
  

   appears, 
  and 
  the 
  nuvio-marine 
  

   Crag 
  only 
  shows 
  itself 
  by 
  two 
  

   small 
  bosses 
  rising 
  through 
  

   the 
  beach 
  near 
  the 
  south 
  ex- 
  

   tremity 
  of 
  the 
  cliff. 
  

  

  The 
  evidences 
  thus 
  afforded 
  

   of 
  the 
  ice 
  at 
  the 
  time 
  of 
  its 
  

   greatest 
  extension 
  in 
  East 
  

   Anglia 
  streaming 
  in 
  no 
  great 
  

   thickness 
  over 
  the 
  land 
  near- 
  

   est 
  the 
  sea, 
  but 
  lying 
  in 
  

   greater 
  thickness 
  a 
  few 
  miles 
  

   inland, 
  while 
  its 
  main 
  outlet 
  

   was 
  by 
  glaciers 
  that 
  de- 
  

   scended 
  below 
  the 
  sea-level 
  

   of 
  the 
  time, 
  and 
  issued 
  through 
  

   the 
  more 
  considerable 
  valleys 
  

   of 
  East 
  Anglia 
  as 
  fiords, 
  ap- 
  

   pear 
  to 
  me 
  quite 
  to 
  coincide 
  

   with 
  the 
  description 
  given 
  of 
  

   the 
  shores 
  of 
  Davis' 
  .Straits 
  

   and 
  Baffin's 
  Bay 
  in 
  the 
  Journal 
  

   of 
  the 
  Society 
  (vol.ix. 
  p. 
  301), 
  

   by 
  Dr. 
  Sutherland, 
  whose 
  

   illustration 
  of 
  a 
  part 
  of 
  those 
  

   shores, 
  by 
  permission 
  of 
  the 
  

   Council, 
  I 
  here 
  give. 
  

  

  We 
  have 
  only 
  to 
  substitute 
  

   the 
  low 
  land 
  and 
  soft 
  sands 
  

   and 
  clays 
  of 
  the 
  East 
  Anglian 
  

   shore 
  for 
  the 
  rocky 
  soil 
  and 
  

   more 
  elevated 
  land 
  of 
  Baffin's 
  

   Bay, 
  over 
  which, 
  in 
  Dr. 
  Su- 
  

   therland's 
  representation, 
  the 
  

   ice 
  in 
  varying, 
  but 
  in 
  no 
  case 
  

   great, 
  thickness 
  is 
  streaming 
  

   off 
  from 
  the 
  thicker 
  ice 
  more 
  

   inland, 
  to 
  form, 
  in 
  my 
  opi- 
  

   nion, 
  an 
  accurate 
  idea 
  of 
  the 
  

   shore(alittle 
  further 
  eastward 
  

   than 
  the 
  present) 
  of 
  North- 
  

   east 
  Suffolk 
  at 
  the 
  time 
  when 
  

   the 
  ice 
  of 
  the 
  Chalky 
  Clay 
  

   reached 
  its 
  greatest 
  exten- 
  

   sion, 
  and 
  before 
  it 
  shrank 
  

   from 
  the 
  plateaux, 
  to 
  become
