  COWPEE 
  EEED 
  ON 
  THE 
  BED 
  EOCKS 
  [May

  897, 
  

  

  these 
  beds 
  by 
  the 
  intrusion 
  of 
  any 
  igneous 
  rock. 
  The 
  sandstone 
  is 
  

   quite 
  similar 
  in 
  lithological 
  characters 
  to 
  many 
  beds 
  in 
  the 
  un- 
  

   doubted 
  Old 
  Red 
  Sandstone 
  around 
  Waterford 
  ; 
  and 
  the 
  basal 
  breccia 
  

   may 
  be 
  compared 
  with 
  that 
  of 
  Dunmore. 
  

  

  The 
  vertical 
  line 
  of 
  junction 
  of 
  the 
  red 
  beds 
  with 
  the 
  igneous 
  

   rocks 
  on 
  the 
  east 
  is 
  obscure, 
  for 
  the 
  adjacent 
  rocks 
  are 
  stained 
  red 
  

   by 
  the 
  washing 
  down 
  of 
  the 
  shaly 
  material 
  ; 
  small 
  slips 
  also 
  have 
  

   taken 
  place 
  which 
  are 
  now 
  grass-grown, 
  and 
  a 
  spring 
  here 
  breaks 
  

   out. 
  There 
  is, 
  however, 
  everything 
  to 
  suggest 
  a 
  fault 
  on 
  this 
  side 
  

   too, 
  by 
  the 
  position 
  and 
  characters 
  of 
  the 
  igneous 
  rocks 
  seen 
  beyond 
  

   this 
  talus 
  and 
  grass. 
  

  

  The 
  next 
  patch 
  is 
  in 
  the 
  large 
  Ballydouane 
  Bay, 
  and 
  is 
  the 
  one 
  

   described 
  with 
  more 
  or 
  less 
  minuteness 
  by 
  all 
  the 
  writers 
  on 
  these 
  

   red 
  rocks 
  of 
  the 
  coast. 
  Beginning 
  at 
  the 
  western 
  corner 
  of 
  the 
  bay, 
  

   west 
  of 
  the 
  road 
  leading 
  down 
  to 
  the 
  beach, 
  we 
  find 
  the 
  low 
  cliffs 
  — 
  

   not 
  more 
  than 
  40 
  feet 
  high 
  at 
  this 
  point 
  — 
  composed 
  of 
  a 
  curious 
  

   banded 
  rock 
  (ophiolite 
  of 
  Kinahan), 
  much 
  resembling 
  serpentine 
  in 
  

   appearance, 
  but 
  containing 
  fossils, 
  dipping 
  most 
  distinctly 
  60° 
  N.N.W. 
  

   — 
  that 
  is, 
  into 
  the 
  face 
  of 
  the 
  cliff. 
  On 
  the 
  east, 
  separated 
  from 
  

   these 
  banded 
  rocks 
  by 
  

  

  a 
  grass 
  -grown 
  talus 
  Fig.

  Ground-plan 
  of

  side 
  

   slope, 
  a 
  few 
  yards 
  f 
  Bally 
  douane 
  Bay. 
  

  

  wide, 
  we 
  find 
  red 
  and 
  

   yellow 
  sandstones 
  with 
  

   thin 
  but 
  frequent 
  bands 
  

   of 
  fine 
  conglomerate, 
  

   made 
  up 
  of 
  white 
  

   quartz 
  and 
  other 
  peb- 
  

   bles, 
  dipping 
  30° 
  N.E. 
  

   These 
  form 
  the 
  low 
  

   cliffs. 
  On 
  the 
  foreshore 
  

   we 
  see 
  these 
  sand- 
  

   stones 
  ending 
  abruptly 
  

   against 
  the 
  serpen 
  - 
  

   tinous 
  bedded 
  rocks 
  

   along 
  a 
  line 
  of 
  fault 
  

   which 
  most 
  clearly 
  

   shows 
  the 
  two 
  rocks 
  

   in 
  contact 
  (see 
  plan, 
  

   fig. 
  2). 
  Thus 
  the 
  

   western 
  boundary 
  of 
  

   the 
  red 
  beds 
  of 
  Bally- 
  

   douane 
  Bay 
  is 
  a 
  line 
  of 
  fault. 
  An 
  isolated 
  pyramidal 
  mass 
  of 
  the 
  

   red 
  sandstones 
  and 
  conglomerates 
  stands 
  in 
  front 
  of 
  the 
  cliffs 
  at 
  this 
  

   point, 
  a 
  few 
  yards 
  west 
  of 
  the 
  gap 
  occupied 
  by 
  the 
  stream 
  and 
  

   road. 
  This 
  mass 
  shows 
  the 
  beds 
  dipping 
  N.E. 
  at 
  45°. 
  

  

  There 
  is 
  thus 
  absolutely 
  no 
  evidence 
  here 
  that 
  the 
  red 
  rocks 
  are 
  

   interbedded 
  with 
  the 
  neighbouring 
  strata, 
  and 
  I 
  cannot 
  understand 
  

   the 
  succession 
  of 
  beds 
  which 
  is 
  tabulated 
  in 
  the 
  Survey 
  Memoir 
  as 
  

   occurring 
  on 
  the 
  western 
  side 
  of 
  Ballydouane
