  the 
  Land-shells 
  and 
  sediment 
  would 
  be 
  brought 
  into 
  it 
  by 
  means 
  of 
  

   the 
  springs 
  and 
  land-floods, 
  and 
  the 
  shelly 
  bed 
  is 
  accounted 
  for. 
  

  

  The 
  formation 
  of 
  a 
  pond 
  as 
  the 
  consequence 
  of 
  a 
  landslip 
  is 
  stated 
  

   bv 
  the 
  author 
  to 
  be 
  not 
  inconsistent 
  with 
  the 
  known 
  results 
  of 
  the 
  

   action 
  of 
  springs 
  issuing 
  from 
  the 
  beds 
  of 
  the 
  Fuller's 
  Earth. 
  Thus 
  

   at 
  Brimscombe, 
  three 
  miles 
  distant, 
  these 
  springs 
  have 
  at 
  some 
  former 
  

   period 
  caused 
  an 
  extensive 
  slip 
  of 
  Fuller's 
  Earth, 
  which 
  is 
  now 
  found 
  

   covering 
  the 
  bottom 
  of 
  the 
  valley 
  in 
  a 
  stratum 
  of 
  considerable 
  thick- 
  

   ness, 
  its 
  original 
  position 
  being 
  at 
  an 
  elevation 
  of 
  at 
  least 
  400 
  feet 
  

   above 
  the 
  valley 
  ; 
  and 
  at 
  Chalford, 
  in 
  the 
  same 
  locality, 
  there 
  is, 
  at 
  

   this 
  time, 
  and 
  from 
  the 
  same 
  cause, 
  another 
  mass 
  of 
  Fuller's 
  Earth, 
  

   covering 
  a 
  surface 
  of 
  about 
  two 
  acres, 
  on 
  its 
  way 
  downwards 
  into 
  the 
  

   valley. 
  

  

  If 
  it 
  be 
  conceded 
  that 
  a 
  pond 
  or 
  small 
  lake 
  once 
  existed 
  upon 
  the 
  

   site 
  of 
  the 
  shelly 
  bed, 
  it 
  follows 
  of 
  course, 
  from 
  the 
  contents 
  of 
  the 
  

   deposit, 
  that 
  it 
  was 
  a 
  place 
  to 
  which 
  the 
  inhabitants 
  of 
  the 
  district 
  

   resorted 
  for 
  various 
  purposes, 
  the 
  animal-charcoal, 
  which 
  is 
  found 
  

   throughout 
  the 
  bed, 
  even 
  to 
  its 
  lowest 
  part, 
  proving 
  that 
  during 
  the 
  

   whole 
  period 
  of 
  its 
  formation 
  the 
  surrounding 
  country 
  was 
  inhabited. 
  

  

  The 
  changes 
  which 
  have 
  taken 
  place 
  in 
  the 
  aspect 
  of 
  the 
  slopes 
  

   and 
  the 
  covering 
  up 
  of 
  the 
  deposit 
  with 
  vegetable 
  mould, 
  from 
  2-4 
  

   feet 
  thick, 
  must 
  have 
  been 
  the 
  work 
  of 
  a 
  very 
  long 
  period, 
  and 
  there 
  

   can 
  be 
  little 
  doubt 
  that 
  the 
  people 
  by 
  whom 
  the 
  Flint 
  Implements 
  

   were 
  formed, 
  and 
  who 
  left 
  behind 
  them 
  other 
  traces 
  of 
  their 
  exist- 
  

   ence, 
  were 
  some 
  of 
  the 
  earliest 
  inhabitants 
  of 
  this 
  country. 
  In 
  

   further 
  proof 
  of 
  this 
  opinion 
  is 
  the 
  fact 
  that 
  Helix 
  lamellata 
  (one 
  of 
  

   the 
  shells 
  mentioned 
  in 
  the 
  list) 
  is 
  not 
  now 
  an 
  inhabitant 
  of 
  this 
  

   part 
  of 
  the 
  country, 
  not 
  being 
  found 
  south 
  of 
  Scarborough*.
