  there 
  is 
  a 
  break, 
  and 
  a 
  little 
  lower 
  down 
  the 
  bed 
  described 
  as 
  

   Upper 
  Freestone 
  is 
  seen. 
  The 
  relation 
  of 
  the 
  sands 
  and 
  Lower 
  

   Trigonia-gvit 
  may 
  also 
  be 
  seen 
  on 
  the 
  eastern 
  side 
  of 
  the 
  hill 
  above 
  

   * 
  The 
  Ring,' 
  near 
  the 
  1000-foot 
  contour-line. 
  Eelative 
  position, 
  

   but 
  not 
  actual 
  sequence, 
  may 
  be 
  observed 
  at 
  ' 
  Roadstone 
  Hole.' 
  

  

  The 
  sands 
  cover 
  a 
  considerable 
  part 
  of 
  the 
  hill, 
  and 
  have 
  been 
  

   extensively 
  worked. 
  It 
  is 
  reported 
  that 
  they 
  were 
  dug 
  for 
  use 
  in 
  

   the 
  Staffordshire 
  potteries, 
  and 
  that 
  they 
  were 
  conveyed 
  thither 
  

   upon 
  the 
  backs 
  of 
  donkeys. 
  The 
  presence 
  of 
  the 
  sand 
  is 
  often 
  indi- 
  

   cated 
  by 
  the 
  gorse-bushes. 
  The 
  stone-bed 
  (No. 
  X, 
  1) 
  is 
  sometimes 
  

   partially 
  disintegrated 
  into 
  nodule 
  - 
  shaped 
  masses, 
  1 
  which 
  then 
  

   have 
  the 
  appearance 
  of 
  boulders, 
  and 
  have 
  been 
  the 
  cause 
  of 
  some 
  

   confusion 
  in 
  the 
  matter 
  of 
  Northern 
  Drift. 
  There 
  is 
  a 
  specimen 
  in 
  

   the 
  Gloucester 
  Museum 
  which 
  was 
  obtained 
  from 
  'Roadstone 
  Hole/ 
  

   and 
  preserved 
  as 
  an 
  example 
  of 
  that 
  drift 
  ! 
  

  

  (£) 
  The 
  Snowshill 
  Clay. 
  2 
  

  

  This 
  clay 
  may 
  be 
  seen 
  at 
  the 
  western 
  side 
  of 
  the 
  hill, 
  lying 
  over 
  

   the 
  Harford 
  Sands, 
  as 
  noted 
  above 
  ; 
  the 
  measurements 
  given 
  were 
  

   taken 
  therefrom. 
  It 
  may 
  also 
  be 
  seen 
  at 
  ' 
  Roadstone 
  Hole 
  ' 
  capping 
  

   the 
  sands 
  just 
  under 
  the 
  turf, 
  and 
  it 
  seems 
  to 
  attain 
  a 
  thickness 
  of 
  

   2 
  feet. 
  At 
  Leckhampton 
  Hill 
  is 
  the 
  first 
  south-westerly 
  exposure, 
  

   a 
  bed 
  2 
  inches 
  in 
  thickness, 
  marked 
  as 
  ' 
  Harford 
  Sands 
  equivalent.' 
  3 
  

   Northward 
  it 
  would 
  seem 
  that 
  the 
  deposit 
  attains 
  considerable 
  

   proportions, 
  for 
  between 
  Snowshill 
  and 
  Broadway 
  is 
  a 
  stratum 
  

   of 
  this 
  clay, 
  whereon 
  grow 
  oak-trees 
  and 
  thorn-bushes— 
  signs 
  of 
  

   an 
  argillaceous 
  bed 
  ; 
  and 
  it 
  must 
  be 
  several 
  feet 
  in 
  thickness, 
  for 
  

   there 
  was 
  a 
  pit 
  about 
  4 
  feet 
  deep, 
  while 
  beyond 
  that 
  the 
  ground 
  rose 
  

   considerably. 
  Therefore, 
  for 
  distinction, 
  the 
  name 
  ' 
  Snowshill 
  ' 
  has 
  

   been 
  used, 
  because 
  this 
  is 
  a 
  bed 
  of 
  considerable 
  economic 
  importance 
  

   (see 
  p. 
  624). 
  It 
  may 
  be 
  remarked 
  that 
  the 
  clay 
  occurs 
  above 
  sand, 
  

   so 
  that 
  the 
  order 
  is 
  

  

  Limestone 
  (Lower 
  Trigonia-gvit), 
  

  

  Clay 
  (Snowshill 
  Clay), 
  

  

  Sand 
  (Harford 
  Sands), 
  

  

  Limestone 
  (Upper 
  Freestone), 
  

  

  which 
  is 
  somewhat 
  unusual. 
  

  

  The 
  chief 
  interest 
  of 
  the 
  further 
  exploration 
  of 
  the 
  Northern 
  

   Cotteswolds 
  will 
  be 
  the 
  development 
  of 
  the 
  Harford 
  Sands 
  and 
  

   Snowshill 
  Clay, 
  or 
  beds 
  nearly 
  contemporaneous 
  therewith. 
  

  

  1 
  The 
  bed 
  consists 
  of 
  very 
  fine 
  quartz-grains 
  and 
  calcareous 
  cement. 
  The 
  

   rain 
  gradually 
  dissolves 
  the 
  cement, 
  and 
  leaves 
  the 
  grains 
  incoherent 
  as 
  sand.
