  These 
  lists 
  show 
  how 
  wide 
  the 
  distribution 
  of 
  Palaeolithic 
  flint 
  

   implements 
  in 
  the 
  Ightham 
  district 
  is 
  *. 
  It 
  will 
  be 
  seen 
  by 
  refe- 
  

   rence 
  to 
  the 
  Map 
  (PI. 
  IX.) 
  and 
  sections 
  that 
  they 
  extend 
  far 
  beyond 
  

   the 
  limits 
  that 
  I 
  have 
  assigned 
  to 
  the 
  river-drifts 
  formed 
  since 
  the 
  

   present 
  hydrographical 
  basins 
  were 
  established. 
  

  

  Of 
  the 
  various 
  localities 
  named 
  above, 
  the 
  only 
  ones 
  which, 
  I 
  

   consider, 
  come 
  within 
  the 
  boundaries 
  of 
  the 
  old 
  course 
  of 
  the 
  Shode, 
  

   at 
  the 
  time 
  that 
  it 
  flowed 
  at 
  its 
  higher 
  levels, 
  are 
  Fane 
  Hill 
  (the 
  

   lower 
  part 
  of 
  it), 
  Coneyfield, 
  Bayshaw, 
  Highfield, 
  Crowhurst, 
  Basted, 
  

   Dunks 
  Green, 
  and 
  Hamptons. 
  Applying 
  the 
  same 
  rule 
  to 
  the 
  

   adjacent 
  Daren 
  t 
  tributary, 
  the 
  known 
  river-drifts 
  are 
  confined 
  to 
  

   Child's 
  Bridge, 
  and 
  possibly 
  to 
  the 
  terrace 
  just 
  below 
  Fuller 
  Street 
  

   and 
  Stonepit; 
  and 
  in 
  the 
  Leybourne 
  Valley 
  to 
  West 
  Mailing 
  and 
  

   Leybourne. 
  All 
  the 
  other 
  places 
  are 
  beyoud 
  the 
  river-boundaries, 
  

   and 
  the 
  presence 
  of 
  palaeolithic 
  implements 
  at 
  those 
  higher 
  levels 
  

   must 
  be 
  accounted 
  for 
  by 
  some 
  other 
  means 
  than 
  those 
  in 
  connexion 
  

   with 
  the 
  former 
  regime 
  of 
  the 
  existing 
  streams. 
  

  

  Character 
  of 
  the 
  Flint 
  Implements. 
  — 
  Until 
  the 
  discoveries 
  of 
  Mr. 
  

  

  * 
  It 
  is 
  probable 
  that 
  their 
  distribution 
  is 
  even 
  more 
  general 
  than 
  here 
  in- 
  

   dicated 
  ; 
  for 
  a 
  certain 
  portion 
  of 
  the 
  land 
  is 
  pasture 
  and 
  alluvial 
  land, 
  

   which 
  prevents 
  the 
  examination 
  of 
  the 
  subsoil.
