﻿PALEOLITHIC 
  FLINT 
  IMPLEMENTS 
  IN 
  KENT.

  Mr. 
  Harrison 
  invited 
  Members 
  of 
  the 
  Society 
  to 
  visit 
  the 
  area 
  

   and 
  examine 
  the 
  district. 
  

  

  Mr. 
  J. 
  Allen 
  Brown 
  agreed 
  with 
  the 
  President 
  as 
  to 
  the 
  subaerial 
  

   origin 
  of 
  some 
  high-level 
  drifts. 
  He 
  believed 
  that 
  many 
  of 
  the 
  Old- 
  

   bury-Hill 
  implements 
  were 
  late 
  palaeolithic 
  forms. 
  In 
  the 
  Thames 
  

   valley 
  the 
  height 
  up 
  to 
  which 
  the 
  implements 
  were 
  found 
  and 
  their 
  

   relation 
  to 
  glacial 
  deposits 
  showed 
  that 
  man 
  then 
  lived 
  in 
  near 
  

   proximity 
  to 
  the 
  ice. 
  

  

  The 
  Author, 
  in 
  reply, 
  regretted 
  that 
  he 
  must 
  disagree 
  with 
  Dr. 
  

   Evans 
  as 
  to 
  the 
  flow 
  of 
  the 
  rivers 
  in 
  the 
  direction 
  which 
  he 
  had 
  

   suggested 
  *. 
  With 
  regard 
  to 
  the 
  erosion 
  of 
  valleys 
  in 
  the 
  Chalk 
  plains 
  

   we 
  did 
  not 
  find 
  implements 
  of 
  the 
  clumsier 
  type 
  in 
  the 
  valleys, 
  

   except 
  under 
  such 
  conditions 
  as 
  to 
  suggest 
  their 
  washing 
  down, 
  but 
  

   on 
  a 
  plateau 
  with 
  the 
  red-clay- 
  with-nints. 
  

  

  He 
  drew 
  a 
  section 
  showing 
  the 
  clay-with- 
  flints 
  ending 
  abruptly 
  

   against 
  the 
  valleys 
  in 
  which 
  the 
  Postglacial 
  drifts 
  were 
  found. 
  

   This 
  high-plateau 
  drift 
  could 
  only 
  have 
  been 
  formed 
  when 
  the 
  Chalk 
  

   extended 
  much 
  further 
  south, 
  as 
  the 
  drift 
  had 
  been 
  derived 
  partly 
  

   from 
  the 
  denudation 
  of 
  the 
  Lower 
  Greensand. 
  Some 
  of 
  the 
  pheno- 
  

   mena 
  seemed 
  to 
  him 
  to 
  be 
  explicable 
  only 
  by 
  ice-action. 
  The 
  im- 
  

   plements 
  from 
  Ash 
  were 
  rare 
  and 
  extremely 
  rudely 
  fashioned 
  ; 
  many 
  

   of 
  them 
  showed 
  incrustations 
  of 
  oxide 
  of 
  iron 
  and 
  sand, 
  which 
  could 
  

   only 
  have 
  been 
  formed 
  when 
  they 
  were 
  imbedded 
  in 
  sand. 
  

  

  * 
  [Mr. 
  F. 
  C. 
  J. 
  Spurred 
  has 
  suggested 
  that 
  the 
  Darent 
  during 
  its 
  earlier 
  

   stages 
  rose 
  in 
  the 
  central 
  Weald, 
  and 
  flowed 
  through 
  the 
  Shode 
  valley 
  at 
  

   Plaxtol, 
  and 
  thus 
  originated 
  the 
  high-level 
  or 
  hill 
  drifts 
  of 
  that 
  valley. 
  One 
  

   objection, 
  amongst 
  others, 
  to 
  this 
  view 
  is 
  that 
  this 
  high-level 
  drift 
  contains 
  no 
  

   Wealden 
  debris, 
  whilst, 
  on 
  the 
  other 
  hand, 
  it 
  consists 
  of 
  Tertiary, 
  Chalk, 
  and 
  

   Lower 
  Greensand 
  debris, 
  all 
  having 
  a 
  transport 
  of 
  from 
  north 
  to 
  south.
