  angular 
  and 
  subangular 
  gravel 
  in 
  a 
  red 
  clayey 
  matrix, 
  almost 
  un- 
  

   stratified, 
  but 
  with 
  a 
  few 
  loamy 
  patches. 
  The 
  stones 
  are 
  prin- 
  

   cipally 
  chalk-flints 
  with 
  a 
  few 
  Greensand 
  pebbles 
  and 
  Tertiary 
  

   sandstone 
  blocks, 
  some 
  of 
  them 
  nine 
  or 
  ten 
  inches 
  long. 
  Its 
  thick- 
  

   ness 
  is 
  about 
  ten 
  or 
  twelve 
  feet. 
  Though 
  less 
  distinctly 
  stratified 
  

   than 
  the 
  gravels 
  of 
  Moulin 
  Quignon, 
  there 
  is 
  a 
  strong 
  general 
  re- 
  

   semblance 
  to 
  them. 
  I 
  have 
  not 
  got 
  the 
  exact 
  measurements 
  of 
  this 
  

   chalk-ridge, 
  but 
  near 
  the 
  Cemetery 
  it 
  probably 
  attains 
  a 
  height 
  of 
  at 
  

   least 
  100 
  feet 
  above 
  the 
  level 
  of 
  the 
  river, 
  and 
  the 
  surface 
  of 
  the 
  

   gravel-beds 
  of 
  which 
  I 
  have 
  been 
  speaking 
  may 
  be 
  about 
  20 
  feet 
  

   lower. 
  As 
  we 
  descend 
  the 
  hill 
  we 
  find 
  the 
  chalk 
  in 
  places 
  coming 
  

   almost 
  to 
  the 
  surface, 
  but 
  at 
  the 
  railway-bridge 
  it 
  is 
  seen 
  that 
  the 
  

   cutting 
  has 
  been 
  carried 
  through 
  beds 
  of 
  brick-earth 
  and 
  gravel, 
  

   resting 
  on 
  flinty 
  chalk-rubble, 
  similar 
  to 
  those 
  exhibited 
  in 
  Mr. 
  

   Harding's 
  brick-pit 
  nearer 
  Salisbury. 
  These 
  beds 
  are 
  continued 
  

   down 
  to 
  the 
  bottom 
  of 
  the 
  valley, 
  and 
  may 
  be 
  traced 
  in 
  various 
  

   clay-pits 
  on 
  the 
  south 
  of 
  the 
  Wilton 
  road. 
  

  

  The 
  relation 
  of 
  the 
  high-level 
  gravels 
  (in 
  which 
  the 
  Implements 
  

   were 
  found) 
  to 
  these 
  lower 
  beds 
  will 
  be 
  best 
  seen 
  in 
  the

  may 
  add 
  that 
  Mr. 
  Prestwich 
  informs 
  me 
  that 
  there 
  are 
  similar 
  

   high-level 
  gravels 
  on 
  the 
  eastern 
  side 
  of 
  the 
  valley 
  of 
  the

  near 
  

   Salisbury. 
  It 
  is 
  needless 
  to 
  enter 
  into 
  any 
  description 
  of 
  the 
  geolo- 
  

   gical 
  character 
  of 
  the 
  low-level 
  beds 
  of 
  drift, 
  as 
  they 
  have 
  already 
  

   been 
  fully 
  described 
  in 
  the 
  paper 
  by 
  Mr. 
  Prestwich*, 
  to 
  which 
  I 
  

   have 
  before 
  referred. 
  As, 
  however, 
  the 
  careful 
  researches 
  of 
  Dr. 
  

   Blackmore 
  have 
  considerably 
  extended 
  the 
  fauna 
  of 
  this 
  deposit 
  since 
  

   that 
  paper 
  was 
  written, 
  it 
  will 
  be 
  well 
  to 
  give 
  an 
  amended 
  list 
  of 
  the 
  

   organic 
  remains 
  found 
  in 
  it.
