  BEDS 
  

  

  Park 
  at 
  300', 
  and 
  in 
  the 
  Deer-park 
  at 
  nearly 
  310' 
  ; 
  it 
  is 
  also 
  recorded 
  * 
  

   at 
  Tower 
  Hill, 
  300', 
  and 
  Hagthorn 
  Hill, 
  290'. 
  Dr. 
  Irving 
  has 
  also 
  

   told 
  me 
  of 
  the 
  occurrence 
  of 
  this 
  same 
  bed 
  at 
  300' 
  on 
  Long 
  Hill, 
  

   the 
  -western 
  extension 
  of 
  Goathurst 
  Hill 
  by 
  Ascot 
  ; 
  and 
  we 
  have 
  a 
  

   published 
  section 
  f 
  of 
  the 
  deep 
  well 
  on 
  Ascot 
  Racecourse 
  with 
  115 
  feet 
  

   of 
  Bagshot 
  sand, 
  almost, 
  if 
  not 
  quite, 
  all 
  of 
  which 
  is 
  Lower 
  Bag- 
  

   shot. 
  If 
  we 
  add 
  to 
  this 
  50 
  feet 
  for 
  the 
  Middle 
  Bagshots 
  which 
  

   have 
  been 
  removed, 
  we 
  get 
  300' 
  as 
  the 
  altitude 
  for 
  the 
  pebble-bed. 
  

   Then 
  at 
  Bracknell 
  Station 
  £, 
  Easthampstead 
  Church, 
  the 
  slope 
  of 
  

   Bill 
  Hill, 
  and 
  in 
  sections 
  round 
  Wellington 
  College 
  we 
  get 
  altitudes 
  

   of 
  260' 
  and 
  265'. 
  

  

  Next, 
  at 
  the 
  entrance 
  to 
  the 
  Staff 
  College 
  at 
  Camberley, 
  on 
  the 
  

   Bagshot 
  road, 
  the 
  pebble-bed 
  is 
  recorded 
  at 
  260' 
  §, 
  and 
  as 
  we 
  go 
  

   northward 
  from 
  here 
  we 
  have 
  it 
  at 
  165' 
  || 
  in 
  the 
  well 
  at 
  the 
  Albert 
  

   Orphan 
  Asylum. 
  These 
  two 
  altitudes 
  may 
  seem 
  to 
  differ 
  enor- 
  

   mously, 
  though 
  situated 
  so 
  near 
  together 
  ; 
  but 
  when 
  the 
  dip 
  is 
  

   calculated 
  out 
  it 
  only 
  gives 
  a 
  slope 
  of 
  a 
  little 
  over 
  J°. 
  

  

  On 
  the 
  Railway 
  between 
  Bagshot 
  and 
  Ascot 
  I 
  have 
  found 
  the 
  

   pebble-bed 
  at 
  230', 
  240', 
  and 
  255', 
  as 
  shown 
  on 
  the 
  map, 
  and 
  on 
  

   Chobham 
  Common 
  as 
  follows 
  : 
  — 
  

  

  Hill 
  above 
  Titlarks 
  Farm 
  235' 
  

  

  Cross 
  Eoad 
  near 
  Staples 
  Hill

  Staples

  Windlesham 
  (near 
  Mrs. 
  Bothery's) 
  200' 
  

  

  Church 
  200' 
  

  

  At 
  Barrow 
  Hills 
  the 
  house 
  is 
  about 
  175', 
  and 
  the 
  well 
  there 
  

   (from 
  particulars 
  kindly 
  furnished 
  by 
  Rev. 
  A. 
  Bramwell) 
  passes 
  

   through 
  

  

  ft. 
  

  

  Clay 
  (Middle 
  Bagshot) 
  8 
  

  

  Fine 
  Sand 
  (Lower 
  Bagshot) 
  37 
  

  

  Total 
  45 
  

  

  Adding 
  50 
  feet 
  for 
  the 
  rest 
  of 
  the 
  Middle 
  Bagshot, 
  we 
  get 
  225' 
  

   for 
  the 
  restored 
  altitude. 
  

  

  For 
  St. 
  Anne's 
  Hill, 
  Chertseylf, 
  we 
  have 
  220' 
  or 
  230', 
  and 
  for 
  

   St. 
  George's 
  Hill, 
  Weybridge, 
  a 
  similar 
  height, 
  230'. 
  

  

  Coming 
  down 
  the 
  L. 
  and 
  S. 
  W. 
  main 
  line 
  we 
  find 
  it 
  at 
  200', 
  

   by 
  Whitsheet 
  near 
  Woking 
  station, 
  and 
  at 
  185' 
  on 
  the 
  hill 
  by 
  

   The 
  Hermitage 
  near 
  Woking 
  Convict 
  prison. 
  

  

  "Now 
  we 
  come 
  to 
  a 
  series 
  of 
  altitudes 
  running 
  due 
  north 
  from 
  

   Worplesdon, 
  175', 
  by 
  Dawson's 
  Well 
  160', 
  and 
  by 
  Dawnay's 
  Hill 
  

   west 
  of 
  Woking 
  Cemetery, 
  about
