  over 
  the 
  bridge 
  being 
  N 
  2o° 
  E. 
  The 
  balance 
  walls 
  of 
  the 
  abutments 
  have 
  

   been 
  broken 
  and 
  forced 
  back, 
  and 
  this, 
  with 
  the 
  sinking 
  of 
  the 
  abutments, 
  has 
  

   caused 
  the 
  line 
  over 
  the 
  bridge 
  to 
  be 
  arched 
  and 
  the 
  girders 
  to 
  be 
  torn 
  apart 
  at 
  

   their 
  junction 
  on 
  the 
  centre 
  pier, 
  which 
  centre 
  pier 
  was 
  not 
  affected 
  by 
  the 
  

   earthquake. 
  The 
  embankment 
  on 
  the 
  north 
  side 
  of 
  the 
  bridge 
  was 
  badly 
  

   broken 
  down. 
  

  

  Juri 
  Bridge, 
  mile 
  212. 
  — 
  'The 
  two 
  centre 
  piers 
  have 
  moved 
  18 
  inches 
  bodily 
  

   towards 
  one 
  another 
  and 
  are 
  not 
  tilted. 
  

  

  Markal 
  Bridge. 
  — 
  The 
  piers 
  on 
  the 
  east 
  side 
  of 
  the 
  bridge 
  are 
  leaning 
  towards 
  

   the 
  west, 
  and 
  the 
  piers 
  on 
  the 
  west 
  side 
  towards 
  the 
  east. 
  

  

  Manho 
  River 
  Bridge. 
  — 
  The 
  line 
  over 
  this 
  is 
  in 
  a 
  direction 
  of 
  N. 
  15 
  E, 
  

   and 
  the 
  piers 
  are 
  little, 
  if 
  at 
  all, 
  damaged. 
  The 
  north 
  abutment 
  wall 
  and 
  

   the 
  adjoining 
  embankment 
  are 
  broken 
  down 
  and 
  the 
  banks 
  of 
  the 
  river 
  on 
  this 
  

   side 
  are 
  badly 
  cracked. 
  

  

  Dhulai 
  Bridge, 
  mile 
  188. 
  — 
  The 
  centre 
  pier 
  is 
  leaning 
  to 
  one 
  side 
  and 
  the 
  line 
  

   on 
  the 
  top 
  is 
  curved, 
  and 
  the 
  end 
  piers 
  are 
  leaning 
  inwards. 
  The 
  original 
  

   direction 
  of 
  the 
  bridge 
  was 
  N 
  42 
  E 
  ; 
  the 
  embankment 
  and 
  river 
  bank 
  on 
  the 
  

   south-west 
  side 
  are 
  both 
  very 
  badly 
  broken 
  down. 
  

  

  Khwai 
  Bridge, 
  mile 
  162, 
  near 
  Shaistaganj 
  '.—The 
  direction 
  of 
  the 
  line 
  over 
  

   the 
  bridge 
  is 
  nearly 
  east 
  and 
  west. 
  The 
  abutment 
  wall 
  on 
  the 
  eastern 
  side 
  is 
  

   leaning 
  over 
  to 
  the 
  east 
  ; 
  it 
  has 
  sunk 
  about 
  2 
  feet 
  and 
  its 
  balance 
  wall 
  is 
  broken 
  

   off. 
  The 
  next 
  pier 
  is, 
  however, 
  leaning 
  towards 
  the 
  west, 
  and 
  the 
  girder 
  between 
  

   the 
  abutment 
  and 
  this 
  pier 
  has 
  slipped 
  off 
  and 
  is 
  now 
  supported 
  on 
  a 
  pile 
  of 
  

   sleepers. 
  The 
  face 
  of 
  the 
  abutment 
  has 
  a 
  dip 
  of 
  84 
  to 
  the 
  west 
  and 
  the 
  face 
  of 
  

   the 
  pier 
  a 
  dip 
  of 
  8i° 
  to 
  the 
  east. 
  

  

  Besides 
  the 
  breaking 
  down 
  the 
  embankment, 
  the 
  railway 
  line 
  is 
  in 
  many 
  

   cases 
  bent 
  into 
  curves. 
  These 
  had 
  almost 
  all 
  been 
  straightened 
  out 
  again 
  at 
  the 
  

   time, 
  of 
  my 
  visit, 
  but 
  some 
  severe 
  cases 
  were 
  still 
  to 
  be 
  seen. 
  The 
  force 
  required 
  

   to 
  bend 
  the 
  line 
  into 
  curves 
  must 
  have 
  been 
  very 
  great, 
  as 
  in 
  many 
  places 
  the 
  

   steel 
  rails 
  are 
  bent 
  and 
  curved, 
  and 
  the 
  nature 
  of 
  the 
  curving 
  of 
  the 
  line 
  sometimes 
  

   seems 
  to 
  indicate 
  movement 
  of 
  the 
  ground 
  horizontally. 
  

  

  Of 
  the 
  horizontal 
  movement 
  of 
  the 
  ground 
  I 
  was, 
  however, 
  able 
  to 
  obtain 
  a 
  

   definite 
  piece 
  of 
  evidence. 
  Between 
  Daragaonand 
  Shaistaganj 
  the 
  embankment, 
  

   which 
  is 
  quite 
  low, 
  was 
  much 
  broken 
  down 
  and 
  the 
  line 
  twisted 
  into 
  curves 
  for 
  a 
  

   considerable 
  distance, 
  and 
  as 
  I 
  was 
  going 
  over 
  it 
  on 
  a 
  trolley, 
  Mr. 
  F. 
  P. 
  Anderson, 
  

   the 
  Executive 
  Engineer, 
  Shaistaganj 
  Section, 
  Assam-Bengal 
  Railway, 
  pointed 
  

   out 
  to 
  me 
  that 
  the 
  line 
  was 
  shifted 
  several 
  feet 
  from 
  its 
  original 
  position. 
  As 
  the 
  

   alignment 
  here 
  was 
  perfectly 
  straight 
  for 
  a 
  considerable 
  distance 
  and 
  part 
  of 
  it 
  

   had 
  not 
  suffered 
  in 
  the 
  slightest, 
  this 
  could 
  be 
  tested 
  with 
  certainty, 
  and 
  at 
  my 
  

   request 
  Mr. 
  R. 
  K. 
  Coxe, 
  Assistant 
  Engineer, 
  Shaistaganj 
  Section, 
  set 
  up 
  his 
  

   theodolite 
  and 
  took 
  sights 
  along 
  the 
  line. 
  The 
  place 
  we 
  chose 
  to 
  test 
  was 
  a 
  small 
  

   bridge 
  of 
  three 
  20 
  feet 
  spans 
  in 
  mile 
  164, 
  which 
  was 
  in 
  the 
  centre 
  of 
  the 
  disturbed 
  

   portion 
  : 
  this 
  bridge 
  was 
  somewhat 
  cracked 
  and 
  broken, 
  but 
  it 
  was 
  absolutely 
  

   certain 
  that 
  it 
  had 
  not 
  moved 
  relatively 
  to 
  the 
  surrounding 
  country 
  and 
  trees, 
  yet 
  

   the 
  theodolite 
  showed 
  that 
  the 
  centre 
  of 
  the 
  bridge 
  was 
  6 
  feet 
  9 
  inches 
  out 
  of 
  the 
  

   straight 
  line. 
  At 
  the 
  time 
  it 
  was 
  built 
  it 
  was 
  6 
  inches 
  out 
  and 
  so 
  now 
  it 
  is 
  6 
  feet
