  shales 
  of 
  Geanies 
  are 
  the 
  equivalents 
  of 
  the 
  Caithness 
  flags, 
  and, 
  like 
  

   the 
  latter, 
  they 
  contain, 
  in 
  the 
  joints, 
  asphaltum 
  similar 
  to 
  that 
  which 
  

   has 
  recently 
  been 
  obtained 
  from 
  the 
  Old 
  Red 
  Sandstone 
  at 
  Mount 
  

   Gerald, 
  near 
  Dingwall 
  *, 
  but 
  not 
  in 
  such 
  great 
  quantities. 
  These 
  

   equivalents 
  of 
  the 
  Caithness 
  flags, 
  measured 
  from 
  the 
  top 
  of 
  the 
  

   Lower 
  Old 
  Red 
  series 
  to 
  the 
  point 
  where 
  they 
  disappear 
  under 
  strata 
  

   referable 
  to 
  the 
  Upper 
  Old 
  Red, 
  have 
  a 
  thickness 
  of 
  about 
  350 
  feet, 
  

   and 
  their 
  dip 
  conforms 
  to 
  the 
  underlying 
  and 
  overlying 
  strata, 
  being 
  

   towards 
  the 
  N.W. 
  at 
  25°. 
  At 
  Geanies 
  the 
  anticlinal 
  before 
  alluded 
  

   to 
  is 
  very 
  distinct, 
  the 
  strata 
  on 
  the 
  cliff 
  having 
  the 
  usual 
  inclina- 
  

   tion 
  of 
  the 
  land-rocks, 
  while 
  on 
  the 
  shore 
  the 
  beds 
  have 
  a 
  directly 
  

   opposite 
  dip. 
  Here 
  the 
  rocks 
  forming 
  the 
  anticlinal 
  sink, 
  and 
  con- 
  

   sequently 
  newer 
  beds 
  present 
  themselves 
  than 
  those 
  towards 
  the 
  

   south-west, 
  where, 
  as 
  before 
  stated, 
  the 
  axis 
  rises 
  in 
  vertical 
  position. 
  

  

  About 
  a 
  mile 
  north-north-east 
  of 
  Geanies 
  Hill, 
  at 
  Tarrol, 
  the 
  repre- 
  

   sentatives 
  of 
  the 
  Caithness 
  flags 
  are 
  succeeded 
  by 
  strata 
  appertaining 
  

   to 
  the 
  higher 
  members 
  of 
  the 
  Old 
  Red 
  formation, 
  and 
  consisting 
  of 
  

   whitish 
  sandstones 
  with 
  red 
  blotches, 
  which 
  continue 
  along 
  the 
  coast 
  for 
  

   about 
  a 
  mile 
  and 
  a 
  half, 
  to 
  Rockfield. 
  At 
  Tarrol 
  the 
  anticlinal 
  makes 
  

   a 
  turn 
  to 
  the 
  east 
  for 
  a 
  short 
  distance, 
  but 
  soon 
  assumes 
  its 
  original 
  

   course. 
  From 
  Rockfield 
  to 
  Ballone 
  Castle 
  the 
  same 
  rock 
  occurs, 
  and 
  

   in 
  this 
  interval 
  a 
  slight 
  roll 
  is 
  seen 
  in 
  the 
  rocks 
  on 
  the 
  coast. 
  

  

  A 
  short 
  distance 
  north-north-east 
  of 
  Ballone 
  Castle, 
  the 
  strata 
  on 
  

   the 
  shore 
  consist 
  of 
  similar 
  sandstones 
  with 
  flexures 
  in 
  them 
  ; 
  and 
  

   about 
  half 
  a 
  mile 
  beyond 
  Ballone 
  Castle, 
  in 
  the 
  cliffs, 
  reddish 
  shales, 
  

   reposing 
  upon 
  sandstone, 
  and 
  supporting 
  white 
  cherty 
  strata, 
  having 
  

   the 
  normal 
  north-west 
  dip, 
  are 
  seen. 
  These 
  shales 
  are 
  in 
  some 
  

   spots 
  greenish 
  white 
  in 
  colour, 
  like 
  those 
  immediately 
  overlying 
  the 
  

   reptiliferous 
  sandstones 
  of 
  Lossiemouth. 
  

  

  The 
  surfaces 
  of 
  the 
  flags 
  associated 
  with 
  these 
  shales 
  are 
  marked
