  WYNNE 
  ON 
  SOME 
  EEATUEES 
  IN 
  THE 
  

  

  tain, 
  on 
  the 
  Indus 
  below 
  Attock. 
  Red 
  and 
  variegated 
  gypseous 
  

   rocks 
  resembling 
  those 
  in 
  the 
  Murree 
  group 
  previously 
  mentioned, 
  

   occur 
  far 
  down 
  in 
  the 
  ravine 
  of 
  the 
  Haro 
  river 
  near 
  its 
  source, 
  and 
  at 
  

   Doongagully 
  on 
  the 
  new 
  mountain-road 
  from 
  Murree 
  to 
  Abbottabad, 
  

   while 
  the 
  possibility 
  of 
  the 
  extension 
  of 
  the 
  hill 
  type 
  of 
  Nummu- 
  

   litic 
  limestone 
  southwards 
  beneath 
  the 
  Pot'war 
  country 
  is 
  supported 
  

   by 
  its 
  reappearance 
  at 
  the 
  hill 
  of 
  Khairee 
  Moorut, 
  ten 
  miles 
  south 
  

   of 
  the 
  junction-line 
  referred 
  to, 
  and 
  west 
  by 
  south 
  from 
  Eawul 
  

   Pindi. 
  

  

  Although 
  the 
  line 
  of 
  junction 
  presents 
  ordinarily 
  the 
  appearance 
  

   of 
  a 
  single 
  line 
  of 
  contact 
  (often 
  concealed 
  owing 
  to 
  its 
  position 
  at 
  

   the 
  foot 
  of 
  hills), 
  this 
  is 
  not 
  a 
  constant 
  condition 
  ; 
  for 
  it 
  is 
  accompa- 
  

   nied 
  in 
  places 
  by 
  somewhat 
  parallel 
  lines 
  of 
  the 
  same 
  kind 
  situated 
  

   within 
  very 
  short 
  distances, 
  and 
  traceable 
  into 
  close 
  convergence, 
  if 
  

   not 
  into 
  absolute 
  unity, 
  with 
  the 
  main 
  one 
  (see 
  section, 
  fig. 
  3). 
  It 
  

   also 
  throws 
  off 
  a 
  branch 
  north 
  of 
  Eawul 
  Pindi, 
  having 
  all 
  the 
  

   characters 
  by 
  which 
  it 
  is 
  itself 
  distinguished, 
  and 
  bringing 
  the 
  same 
  

   sort 
  of 
  Lower 
  Murree 
  rocks 
  into 
  junction 
  with 
  the 
  Hill-limestones. 
  

   This 
  branch, 
  diverging 
  at 
  an 
  acute 
  angle 
  from 
  the 
  north 
  side 
  of 
  the 
  

   line, 
  passes 
  westward 
  along 
  the 
  outer 
  foot 
  of 
  the 
  ridge 
  behind 
  

   which 
  are 
  the 
  ruins 
  of 
  the 
  ancient 
  Taxila 
  at 
  Shah-ka-deri. 
  

  

  The 
  whole 
  aspect 
  of 
  the 
  contact 
  along 
  this 
  line 
  presents 
  none 
  of 
  

   the 
  features 
  or 
  irregular 
  outlines 
  which 
  might 
  be 
  expected 
  to 
  result 
  

   from 
  unconformity, 
  overlap, 
  or 
  limit 
  of 
  deposition 
  ; 
  and, 
  further, 
  

   it 
  might 
  be 
  urged 
  that 
  nowhere 
  along 
  the 
  junction 
  are 
  the 
  newer 
  

   rocks 
  on 
  one 
  side 
  of 
  the 
  line 
  or 
  its 
  branches 
  made 
  up 
  of 
  any 
  recog- 
  

   nizable 
  detritus 
  of 
  the 
  older 
  beds 
  on 
  the 
  other 
  side 
  ; 
  nor, 
  indeed, 
  

   are 
  any 
  prominent 
  coarse 
  detrital 
  deposits, 
  such 
  as 
  might 
  indicate 
  

   an 
  adjacent 
  shore, 
  to 
  be 
  found 
  in 
  the 
  lower 
  strata 
  of 
  the 
  Murree 
  

   group, 
  a 
  few 
  minor 
  beds 
  of 
  coarse 
  sandstone 
  at 
  one 
  part 
  of 
  the 
  

   junction 
  only 
  (in 
  section, 
  fig. 
  3, 
  b 
  l 
  ) 
  having 
  been 
  met 
  with 
  along 
  the 
  

   whole 
  region 
  of 
  contact 
  from 
  Oori 
  to 
  Kohat, 
  a 
  distance 
  of 
  fully 
  200 
  

   miles. 
  Nor 
  does 
  it 
  appear 
  that 
  the 
  basal 
  beds 
  of 
  the 
  known 
  Tertiary 
  

   deposits 
  in 
  the 
  Simla 
  area 
  along 
  their 
  inner 
  (and 
  even 
  more 
  ex- 
  

   tended) 
  boundary, 
  differ 
  in 
  these 
  respects 
  from 
  the 
  junction 
  beds 
  of 
  

   the 
  Tertiary 
  belt 
  with 
  the 
  " 
  Hill-rocks 
  " 
  in 
  this 
  region. 
  

  

  The 
  contact 
  here, 
  on 
  the 
  contrary, 
  presents 
  straight 
  or 
  but 
  slightly 
  

   curved 
  lines, 
  like 
  those 
  of 
  fractured 
  dislocation, 
  without 
  sinuosities 
  

   resembling 
  deep 
  bays, 
  creeks, 
  or 
  promontories 
  ; 
  nor 
  are 
  there 
  visible 
  

   signs 
  of 
  islands 
  lying 
  off 
  the 
  supposed 
  ancient 
  coast, 
  the 
  detached 
  

   elongated 
  hill 
  of 
  Khairee 
  Moorut 
  being 
  apparently 
  enclosed 
  between 
  

   lines 
  of 
  fault. 
  

  

  In 
  a 
  case 
  of 
  ordinary 
  unconformity 
  or 
  overlap 
  subjected 
  to 
  denu- 
  

   dation, 
  discordant 
  patches 
  of 
  the 
  Murree 
  beds 
  might 
  be 
  expected 
  to 
  

   occur 
  resting 
  on 
  the 
  older 
  rocks 
  ; 
  but 
  these 
  have 
  not 
  been 
  met 
  with, 
  

   any 
  detached 
  portions 
  which 
  have 
  been 
  found 
  being 
  apparently 
  let 
  in 
  

   among 
  the 
  older 
  rocks 
  by 
  faults, 
  rather 
  than 
  folded 
  into 
  contortions. 
  

   16. 
  Under 
  all 
  these 
  circumstances 
  it 
  is 
  difficult 
  to 
  recognize 
  in 
  

   this 
  and 
  the 
  Simla 
  region 
  the 
  same 
  relations 
  among 
  formations 
  or 
  

   groups, 
  several 
  of 
  which 
  may 
  be 
  fairly 
  considered 
  identical 
  and 
  in
