﻿THE 
  EPICENTRAL 
  TRACT.

  hundred 
  yards 
  up 
  stream 
  from, 
  where 
  the 
  Chedrang 
  is 
  joined 
  by 
  

   a 
  considerable 
  tributary 
  from 
  the 
  east, 
  just 
  where 
  the 
  village 
  of 
  

   Dalbot 
  is 
  marked 
  on 
  sheet 
  124 
  of 
  the 
  Atlas 
  of 
  India. 
  At 
  this 
  

   place 
  the 
  destructive 
  energy 
  of 
  the 
  earthquake 
  is 
  very 
  marked. 
  

   Huge 
  blocks 
  of 
  granite, 
  ten 
  and 
  twenty 
  feet 
  in 
  diameter, 
  have 
  been 
  

   dislodged 
  from 
  their 
  positions 
  and 
  thrown 
  about. 
  One 
  block, 
  

   roughly 
  cubical 
  and 
  about 
  40 
  ft. 
  X 
  30 
  ft. 
  X 
  30 
  ft., 
  happened 
  to 
  lie 
  across 
  

   the 
  line 
  of 
  fault 
  and 
  was 
  overturned 
  by 
  it. 
  Clumps 
  of 
  bamboos 
  were 
  

   bodily 
  overturned, 
  and 
  bamboos 
  and 
  trees, 
  even 
  where 
  still 
  standing, 
  

   were 
  killed, 
  evidently 
  by 
  the 
  violence 
  of 
  the 
  shock 
  ; 
  in 
  such 
  a 
  

   climate 
  it 
  is 
  impossible 
  to 
  attribute 
  their 
  death 
  merely 
  to 
  a 
  loosening 
  

   of 
  the 
  soil 
  and 
  consequent 
  drying 
  up 
  of 
  the 
  roots. 
  

  

  Near 
  the 
  junction 
  of 
  the 
  tributary 
  referred 
  to 
  above, 
  and 
  quite 
  

   200 
  feet 
  or 
  more 
  in 
  a 
  direct 
  line 
  from 
  the 
  main 
  fault, 
  the 
  gneiss 
  in 
  

   the 
  Chedrang 
  riverbed 
  was 
  seen 
  to 
  have 
  undergone 
  some 
  disturbance, 
  

   and 
  along 
  numerous 
  planes 
  of 
  jointing, 
  or 
  old 
  slickensides, 
  a 
  small 
  

   movement 
  of 
  a 
  few 
  inches 
  had 
  taken 
  place, 
  always 
  with 
  the 
  upthrow 
  

   on 
  the 
  east. 
  

  

  Proceeding 
  down 
  the 
  main 
  valley, 
  the 
  fault 
  is 
  struck 
  once 
  more, 
  

   after 
  having 
  crossed 
  a 
  spur 
  of 
  the 
  hills 
  to 
  the 
  west 
  of 
  the 
  Chedrang, 
  

   and 
  crosses 
  the 
  river 
  obliquely, 
  forming 
  a 
  waterfall. 
  The 
  throw 
  here 
  

   has 
  sunk 
  to 
  about 
  8 
  feet, 
  the 
  upthrow 
  being 
  still 
  on 
  the 
  east 
  and 
  the 
  

   general 
  course 
  about 
  north-north-west, 
  with 
  numerous 
  local 
  irregu- 
  

   larities. 
  The 
  fault 
  keeps 
  close 
  to 
  the 
  river 
  for 
  about 
  half 
  a 
  mile 
  

   crossing 
  it 
  three 
  times 
  and 
  forming 
  a 
  pool 
  when 
  the 
  upthrow 
  is 
  on 
  the 
  

   downstream 
  side, 
  or 
  a 
  waterfall 
  where 
  it 
  is 
  on 
  the 
  upstream 
  side; 
  

   the 
  throw 
  of 
  the 
  fault 
  increases 
  to 
  18 
  feet 
  measured, 
  and 
  probably 
  

   more 
  where 
  there 
  were 
  no 
  means 
  of 
  exact 
  measurement. 
  

  

  The 
  fault 
  has 
  now 
  crossed 
  to 
  the 
  west 
  of 
  the 
  river 
  and 
  continues 
  

   so 
  for 
  nearly 
  a 
  mile. 
  The 
  throw 
  dies 
  out 
  till 
  it 
  is 
  only 
  traceable 
  with 
  

   great 
  difficulty, 
  but 
  increases 
  once 
  more, 
  and 
  the 
  fault 
  crosses 
  a 
  series 
  

   of 
  low 
  spurs, 
  forming 
  three 
  lakelets 
  by 
  blocking 
  the 
  side 
  drainage. 
  

   Two 
  of 
  these 
  are 
  of 
  fair 
  size, 
  of 
  triangular 
  shape, 
  one 
  about 
  300 
  yards 
  

   in 
  length 
  along 
  the 
  barrier 
  formed 
  by 
  the 
  fault, 
  the 
  other, 
  situated
