  red 
  marl 
  and 
  conglomerate 
  would 
  appear 
  to 
  indicate 
  a 
  fault 
  of 
  some 
  

   considerable 
  extent. 
  I 
  have 
  not 
  carried 
  on 
  the 
  diagram 
  so 
  far 
  as 
  

   this 
  termination 
  of 
  the 
  red 
  marl. 
  

  

  Another 
  feature 
  represented 
  in 
  the 
  diagram 
  (fig. 
  3), 
  in 
  connexion 
  

   with 
  the 
  pebble-bed, 
  which 
  I 
  would 
  mention, 
  is 
  that 
  in 
  several 
  places 
  

   there 
  are 
  small 
  interstratified 
  patches 
  of 
  fine 
  red 
  sand, 
  generally 
  of 
  

   about 
  four 
  feet 
  thick, 
  and 
  extending 
  to 
  about 
  forty 
  or 
  fifty 
  feet 
  in 
  

   length, 
  and 
  then 
  thinning 
  out 
  at 
  both 
  ends. 
  In 
  these 
  patches 
  

   oblique 
  lines 
  of 
  deposition 
  are 
  visible, 
  running 
  at 
  a 
  considerable 
  angle 
  

   to 
  the 
  general 
  dip 
  of 
  the 
  beds. 
  These 
  lines 
  extend 
  some 
  distance 
  

   beyond 
  the 
  patches 
  of 
  sand 
  into 
  the 
  pebble-bed, 
  at 
  which 
  places 
  the 
  

   pebbles 
  lie 
  with 
  their 
  longer 
  axis 
  in 
  the 
  direction 
  of 
  this 
  minor 
  

   stratification. 
  Passing 
  through 
  different 
  parts 
  of 
  the 
  bed 
  are 
  also 
  

   strings 
  of 
  oxide 
  of 
  iron, 
  which 
  are 
  locally 
  called 
  " 
  pans," 
  uniting 
  and 
  

   cementing 
  the 
  sand 
  and 
  pebbles 
  together. 
  

  

  The 
  beach 
  from 
  the 
  River 
  Exe 
  on 
  the 
  west 
  to 
  the 
  River 
  Otter 
  on 
  

   the 
  east 
  is 
  mainly 
  composed 
  of 
  the 
  pebbles 
  from 
  this 
  bed, 
  and 
  they 
  

   may 
  be 
  found 
  sparingly 
  for 
  three 
  or 
  four 
  miles 
  beyond 
  Sidmouth. 
  

  

  It 
  will 
  be 
  seen 
  from 
  this 
  that 
  the 
  pebbles 
  on 
  the 
  beach 
  extend 
  

   much 
  further 
  than 
  the 
  pebble-bed 
  in 
  the 
  cliff, 
  from 
  which 
  it 
  might 
  

   be 
  supposed 
  they 
  have 
  directly 
  come. 
  But 
  this 
  is 
  by 
  no 
  means 
  

   certain, 
  since 
  there 
  are 
  other 
  sources 
  from 
  which 
  they 
  might 
  have 
  

   been 
  brought. 
  

  

  On 
  again 
  looking 
  at 
  the 
  map 
  it 
  will 
  be 
  seen 
  that 
  the 
  coast 
  

   we 
  have 
  been 
  describing 
  lies 
  between 
  the 
  Rivers 
  Exe 
  and 
  Otter 
  

   before 
  alluded 
  to, 
  which 
  are 
  distant 
  from 
  each 
  other 
  about 
  six 
  or 
  

   seven 
  miles. 
  The 
  top 
  of 
  the 
  cliffs 
  for 
  nearly 
  the 
  whole 
  of 
  this 
  dis- 
  

   tance 
  is 
  capped 
  by 
  a 
  bed 
  of 
  gravel 
  composed 
  of 
  Budleigh 
  pebbles 
  

   with 
  a 
  considerable 
  admixture 
  of 
  flint, 
  probably 
  one-third. 
  

  

  This 
  same 
  kind 
  of 
  gravel 
  extends 
  up 
  the 
  eastern 
  banks 
  of 
  the 
  

   Exe 
  to 
  Topsham, 
  where 
  it 
  becomes 
  mixed 
  with 
  a 
  considerable 
  

   amount 
  of 
  Carboniferous 
  Grit 
  pebbles 
  ; 
  and 
  also 
  up 
  the 
  banks 
  of 
  

   the 
  Otter 
  as 
  far 
  as 
  Fairmile, 
  or 
  a 
  distance 
  of 
  seven 
  or 
  eight 
  miles. 
  

   These 
  sources 
  might 
  have 
  contributed 
  to 
  the 
  mass 
  of 
  pebbles 
  

   found 
  on 
  the 
  beach 
  ; 
  and 
  this 
  is 
  the 
  more 
  likely 
  as 
  at 
  the 
  mouth 
  of 
  

   the 
  Otter 
  the 
  pebbles 
  are 
  more 
  numerous 
  and 
  in 
  such 
  quantities 
  as 
  

   to 
  form 
  quite 
  a 
  bar 
  across 
  the 
  mouth 
  of 
  that 
  river. 
  

  

  We 
  have 
  said 
  that 
  the 
  dip 
  of 
  the 
  pebble-bed 
  is 
  towards 
  the 
  east, 
  

   consequently 
  the 
  strike 
  would 
  be 
  north 
  and 
  south 
  ; 
  and 
  in 
  this 
  

   direction 
  we 
  have 
  a 
  ridge 
  of 
  hills, 
  extending 
  for 
  about 
  ten 
  or 
  twelve 
  

   miles 
  inland, 
  almost 
  wholly 
  composed 
  of 
  Budleigh 
  pebbles. 
  

  

  Near 
  the 
  termination 
  of 
  this 
  ridge 
  of 
  hills 
  to 
  the 
  north 
  are 
  the 
  

   Straightwayhead 
  gravel-pits, 
  which 
  Sir 
  H. 
  De 
  la 
  Beche, 
  in 
  his 
  

   ' 
  Report 
  of 
  the 
  Geology 
  of 
  Devon,' 
  page 
  396, 
  considers 
  to 
  belong 
  to 
  

   the 
  Plastic-clay 
  series. 
  I 
  have 
  not 
  been 
  able 
  to 
  discover 
  any 
  

   difference 
  in 
  character 
  of 
  the 
  bed 
  at 
  Straightwayhead 
  and 
  the 
  bed 
  

   at 
  Budleigh 
  Salterton. 
  

  

  The 
  pebbles 
  are 
  generally 
  sandstone, 
  but 
  sometimes 
  are 
  so 
  com- 
  

   pact 
  as 
  to 
  assume 
  a 
  quartzite 
  character 
  ; 
  they 
  frequently 
  contain 
  

   flakes 
  of 
  mica, 
  and 
  in 
  some 
  instances 
  small 
  crystals 
  of 
  felspar.
