  on 
  the 
  route 
  traversed 
  along 
  the 
  head 
  of 
  the 
  Chedrang 
  drainage 
  area 
  

   Taking 
  the 
  limit 
  of 
  12 
  miles 
  for 
  its 
  length, 
  this, 
  combined 
  with 
  the 
  

   observed 
  throw, 
  would 
  be 
  sufficient 
  to 
  account 
  for 
  a 
  very 
  severe 
  

   earthquake, 
  and 
  it 
  is 
  fortunate 
  that 
  it 
  was 
  not 
  discovered 
  at 
  the 
  out- 
  

   set 
  of 
  the 
  examination, 
  for 
  it 
  might 
  well 
  have 
  been 
  regarded 
  as 
  a 
  

   sufficient 
  cause, 
  and 
  the 
  area 
  of 
  the 
  examination 
  much 
  restricted. 
  As 
  

   a 
  matter 
  of 
  fact 
  nearly 
  all 
  of 
  the 
  observations 
  which 
  follow 
  were 
  

   made 
  before 
  this 
  great 
  fault 
  was 
  found, 
  and 
  the 
  general 
  result 
  is 
  

   that 
  the 
  Chedrang 
  fault, 
  though 
  by 
  far 
  the 
  most 
  conspicuous, 
  is 
  but 
  a 
  

   small 
  fraction 
  of 
  the 
  total 
  of 
  the 
  permanent 
  changes 
  which 
  accom- 
  

   panied 
  the 
  earthquake. 
  It 
  must 
  consequently 
  be 
  regarded 
  as 
  only 
  

   part 
  of 
  the 
  cause 
  of 
  the 
  earthquake. 
  

  

  About 
  10 
  miles 
  due 
  south 
  of 
  the 
  termination 
  of 
  the 
  Chedrang 
  

   fault 
  is 
  the 
  village 
  of 
  Samin, 
  past 
  which 
  the 
  main 
  road 
  runs 
  south- 
  

   wards 
  from 
  Damra 
  through 
  the 
  Garo 
  Hills. 
  Just 
  before 
  the 
  road 
  

   reaches 
  the 
  Ronghri 
  River 
  there 
  is 
  an 
  abrupt 
  rise 
  of 
  about 
  10 
  feet, 
  

   and 
  on 
  either 
  side 
  of 
  this 
  a 
  low 
  but 
  steep 
  rise, 
  in 
  the 
  surface 
  of 
  

   the 
  alluvial 
  gravels, 
  runs 
  in 
  a 
  WNVV 
  — 
  ESE 
  direction. 
  At 
  first 
  

   sight 
  there 
  is 
  nothing 
  to 
  distinguish 
  this 
  from 
  the 
  natural 
  termina- 
  

   tion 
  of 
  a 
  terrace 
  of 
  valley 
  gravels, 
  except 
  the 
  steepness 
  and 
  bioken^ 
  

   character 
  of 
  the 
  road 
  where 
  it 
  drops 
  from 
  the 
  upper 
  to 
  the 
  lower 
  

   level. 
  On 
  the 
  left 
  of 
  the 
  road, 
  however, 
  there 
  are 
  as 
  shown 
  in 
  

   Plate 
  XIII 
  the 
  remains 
  of 
  an 
  old 
  Garo 
  house. 
  The 
  low 
  cliff 
  just 
  

   mentioned 
  runs 
  through 
  the 
  centre 
  of 
  this, 
  and 
  one 
  of 
  the 
  posts, 
  which 
  

   supported 
  the 
  raised 
  platform 
  of 
  the 
  house, 
  can 
  be 
  seen 
  standing 
  

   below, 
  and 
  another 
  above, 
  the 
  break 
  in 
  the 
  ground 
  level. 
  As 
  the 
  tops 
  

   of 
  these 
  posts 
  must 
  have 
  been 
  on 
  a 
  level 
  with 
  each 
  other 
  when 
  the 
  

   house 
  was 
  built 
  and 
  as 
  the 
  top 
  of 
  the 
  one 
  is 
  now 
  10 
  ft. 
  higher 
  than 
  

   that 
  of 
  the 
  other, 
  they 
  show 
  that 
  the 
  throw 
  of 
  the 
  fault, 
  for 
  such 
  it 
  

   is, 
  was 
  10 
  feet 
  at 
  this 
  point. 
  

  

  This 
  Scimin 
  fault 
  is 
  smaller, 
  both 
  as 
  regards 
  throw 
  and 
  length, 
  

   than 
  the 
  Chedrang 
  fault 
  ; 
  its 
  general 
  course 
  is 
  also 
  different, 
  beino- 
  

   about 
  E 
  30 
  S 
  — 
  W 
  30 
  N 
  and 
  the 
  upthrow 
  is 
  on 
  the 
  southern
