  what 
  is 
  now 
  visible 
  does 
  not 
  at 
  all 
  correspond 
  to 
  the 
  description 
  

   there 
  given. 
  

  

  At 
  the 
  gap 
  in 
  the 
  cliffs 
  formed 
  by 
  the 
  Ballydouane 
  stream 
  we 
  

   find 
  the 
  same 
  red 
  sandstones 
  and 
  conglomerates 
  composing 
  both 
  

   sides 
  of 
  the 
  narrow 
  valley, 
  but 
  the 
  beds 
  are 
  here 
  considerably 
  

   shattered 
  and 
  disturbed 
  for 
  a 
  distance 
  of 
  a 
  few 
  yards, 
  and 
  the 
  cliffs 
  

   are 
  low, 
  irregular, 
  and 
  confused 
  by 
  landslips. 
  However, 
  a 
  dozen 
  

   yards 
  or 
  so 
  to 
  the 
  east 
  of 
  the 
  stream-gap 
  we 
  meet 
  with 
  almost 
  

   vertical 
  beds 
  of 
  coarse 
  quartz-conglomerates, 
  which, 
  as 
  we 
  follow

  S 
  == 
  Fine 
  red 
  sandstones 
  in 
  massive 
  beds, 
  dipping 
  N.W. 
  at 
  80°. 
  

   B 
  = 
  Coarse 
  breccia 
  of 
  underlying 
  igneous 
  rocks 
  (la, 
  lb, 
  etc.) 
  in 
  red 
  sandy 
  

   matrix 
  20 
  feet 
  in 
  thickness, 
  resting 
  unconformably 
  upon 
  the 
  edges 
  of 
  

   the

  rocks

  = 
  Decomposed 
  greyish 
  dolerite 
  ;

  = 
  Dark 
  greenish 
  felsite, 
  intrusive 
  in

  the 
  cliffs 
  eastward, 
  are 
  found 
  to 
  be 
  underlain 
  by 
  finer 
  conglomerates 
  

   and 
  subsidiary 
  alternating 
  beds 
  of 
  red 
  sandstone 
  from 
  2 
  to 
  8 
  

   feet 
  thick. 
  The 
  conglomerates 
  form 
  the 
  greater 
  part 
  of 
  the 
  beds, 
  

   and 
  are 
  composed 
  of 
  subangular 
  or 
  angular 
  pieces 
  of 
  white 
  vein- 
  

   quartz 
  and 
  liver-coloured 
  quartzites. 
  Some 
  of 
  the 
  fragments 
  in 
  the 
  

   coarser 
  beds 
  of 
  conglomerate 
  are 
  as 
  much 
  as 
  8 
  inches 
  long, 
  and 
  can 
  

   scarcely 
  be 
  called 
  pebbles, 
  for 
  they 
  show 
  little 
  sign 
  of 
  rounding 
  or
