  deep. 
  The 
  currents 
  which 
  had 
  dealt 
  with 
  this 
  lowest 
  gravel 
  appear 
  

   to 
  have 
  been 
  extremely 
  violent, 
  judging 
  from 
  the 
  battered 
  condition 
  

   of 
  the 
  flints, 
  and 
  the 
  absence 
  of 
  any 
  matrix 
  but 
  the 
  coarsest 
  clean 
  

   quartzose 
  sand. 
  

  

  Wave-action 
  and 
  storm-beaches 
  would 
  be 
  inferred 
  if 
  near 
  the 
  

   coast, 
  as 
  the 
  gravel 
  rises 
  in 
  curious 
  ridges, 
  which 
  traverse 
  the 
  

   valley 
  from 
  side 
  to 
  side, 
  more 
  or 
  less 
  at 
  right 
  angles 
  to 
  the 
  present 
  

   course 
  of 
  the 
  Kennet.

  all, 
  upon 
  the 
  surface 
  ; 
  but 
  the 
  peat, 
  clay, 
  and 
  marl 
  thin 
  out 
  over 
  

   these 
  old 
  lines 
  of 
  lake-barriers. 
  This 
  is 
  what 
  we 
  expect, 
  and 
  have 
  

   found, 
  in 
  valleys 
  debouching 
  upon 
  the 
  sea-coast 
  ; 
  and 
  at 
  Newbury 
  

   the 
  lacustrine 
  deposits 
  certainly 
  in 
  several 
  instances 
  do 
  repose 
  

   behind 
  successive 
  barriers 
  of 
  this 
  battered 
  gravel. 
  

  

  No 
  traces 
  of 
  shells 
  or 
  organic 
  remains 
  of 
  any 
  kind 
  have, 
  however, 
  

   been 
  forthcoming 
  from 
  this 
  gravel, 
  and 
  we 
  know 
  of 
  no 
  submergence 
  

   at 
  the 
  period 
  whereof 
  we 
  treat 
  which 
  turned 
  the 
  Kennet 
  Valley 
  into 
  

   an 
  arm 
  of 
  the 
  sea 
  ; 
  the 
  wave-action 
  hypothesis 
  is, 
  therefore, 
  unten- 
  

   able. 
  Is 
  it 
  possible 
  that 
  ice-action, 
  or 
  heavy 
  water-action 
  following 
  

   the 
  close 
  of 
  the 
  Ice 
  Age, 
  could 
  have 
  had 
  anything 
  to 
  do 
  with 
  the 
  origin 
  

   of 
  the 
  barriers 
  ? 
  Here 
  fuller 
  investigation 
  is 
  doubtless 
  necessary.
