  raised 
  beach 
  has 
  grown 
  in 
  thickness 
  from 
  1| 
  to 
  12 
  feet. 
  In 
  1890 
  

   there 
  were 
  six 
  feet 
  of 
  sand, 
  with 
  a 
  foot 
  and 
  a 
  half 
  of 
  beach 
  above 
  it. 
  

   There 
  was 
  practically 
  no 
  protection 
  at 
  this 
  date 
  in 
  the 
  shape 
  of 
  

   groynes. 
  In 
  1892 
  the 
  sand 
  had 
  decreased 
  to 
  between 
  3 
  and 
  4 
  feet, 
  

   but 
  the 
  beach 
  remained 
  as 
  in 
  1890. 
  Many 
  falls 
  of 
  cliif 
  took 
  place 
  

   between 
  1892 
  and 
  1895, 
  and 
  at 
  the 
  latter 
  date 
  the 
  beach 
  had 
  

   increased 
  to 
  between 
  4 
  and 
  5 
  feet. 
  The 
  eastern 
  limit 
  of 
  the 
  beds 
  

   had 
  become 
  more 
  clearly 
  defined, 
  the 
  trough 
  in 
  the 
  Chalk 
  in 
  which 
  

   they 
  had 
  been 
  defined 
  taking 
  an 
  upward 
  direction 
  about 
  300 
  yards 
  

   east 
  of 
  the 
  Abergavenny 
  Inn. 
  Many 
  blocks 
  of 
  red 
  sandstone 
  had 
  

   become 
  dislodged, 
  and 
  were 
  lying 
  on 
  the 
  modern 
  beach. 
  In 
  1897, 
  

   10 
  feet 
  of 
  chalk 
  formed 
  the 
  lower 
  portion 
  of 
  the 
  cliff, 
  with 
  8 
  feet 
  

   of 
  raised 
  beach 
  above 
  it 
  in 
  places, 
  but 
  there 
  was 
  a 
  mere 
  trace 
  

   of 
  sand 
  left. 
  The 
  rubble-drift 
  above 
  was 
  seen 
  to 
  be 
  distinctly 
  

   stratified. 
  Many 
  masses 
  of 
  red 
  sandstone 
  had 
  fallen 
  out 
  of 
  the 
  cliff, 
  

   the 
  largest 
  measuring 
  5 
  feet 
  in 
  its 
  greatest 
  dimension. 
  In 
  1899 
  

   the 
  raised 
  beach 
  had 
  reached 
  a 
  thickness 
  of 
  10 
  feet. 
  Great 
  masses 
  

   of 
  moved 
  and 
  reconstructed 
  chalk 
  were 
  observed 
  on 
  the 
  eastern 
  

   boundary 
  embedded 
  in 
  the 
  beach. 
  Two 
  rounded 
  lumps 
  of 
  granite 
  

   were 
  extracted 
  from 
  the 
  beach. 
  In 
  1903, 
  the 
  beach 
  was 
  but 
  a 
  

   little 
  over 
  8 
  feet 
  thick 
  in 
  the 
  exposed 
  parts, 
  but 
  the 
  platform 
  of 
  

   Chalk 
  was 
  li 
  feet 
  thick. 
  The 
  upper 
  portions 
  of 
  the 
  beach, 
  which 
  

   were 
  the 
  least 
  consolidated, 
  had 
  fallen 
  away 
  in 
  such 
  a 
  manner 
  as 
  to 
  

   leave 
  cave-like 
  gaps 
  beneath 
  the 
  rubble. 
  The 
  number 
  of 
  red 
  sand- 
  

   stone 
  blocks 
  which 
  lay 
  on 
  the 
  modern 
  beach 
  was 
  remarkable, 
  forty 
  

   such 
  blocks 
  being 
  counted 
  in 
  a 
  space 
  of 
  50 
  yards 
  square. 
  In 
  1906, 
  

   the 
  raised 
  beach 
  had 
  increased 
  from 
  15 
  to 
  20 
  feet: 
  farther 
  west, 
  

   however, 
  the 
  thickness 
  was 
  not 
  so 
  great. 
  In 
  1908, 
  there 
  were 
  

   17 
  feet 
  of 
  Chalk, 
  12 
  feet 
  of 
  beach. 
  It 
  is 
  noteworthy 
  that 
  as 
  the 
  

   degradation 
  of 
  the 
  cliff 
  proceecFs, 
  the 
  material 
  is 
  rapidly 
  carried 
  

   away 
  by 
  the 
  sea. 
  No 
  talus 
  remains 
  for 
  any 
  length 
  of 
  time, 
  and 
  

   if 
  the 
  material 
  is 
  to 
  be 
  prevented 
  from 
  disappearing 
  into 
  deep 
  water, 
  

   some 
  such 
  contrivance 
  as 
  chain-cable 
  groynes 
  seems 
  to 
  be 
  demanded, 
  

   fixed 
  somewhere 
  between 
  low 
  and 
  high 
  tide-marks. 
  The 
  only 
  

   organic 
  remains 
  observed 
  in 
  the 
  cliffs 
  were 
  some 
  fragments 
  of 
  shells, 
  

   found 
  at 
  the 
  top 
  of 
  the 
  raised 
  beach.
