  extent, 
  it 
  is 
  reported 
  that 
  trunks 
  of 
  trees 
  were 
  thrown 
  out, 
  and 
  from 
  

   places 
  near 
  the 
  foot 
  of 
  the 
  Garo 
  Hills 
  the 
  presence 
  of 
  lumps 
  of 
  coal 
  

   and 
  fossil 
  resin 
  is 
  recorded. 
  The 
  specific 
  gravities 
  of 
  these 
  sub- 
  

   stances 
  is; 
  however, 
  low, 
  and 
  they 
  might 
  be 
  raised, 
  even 
  in 
  pieces 
  of 
  

   considerable 
  size, 
  by 
  no 
  more 
  rapid 
  a 
  current 
  than 
  was 
  necessary 
  to 
  

   raise 
  the 
  sand. 
  

  

  This 
  explanation 
  will 
  not, 
  however, 
  apply 
  to 
  two 
  recorded 
  cases 
  

   of 
  heavy 
  substances 
  being 
  ejected. 
  In 
  the 
  north 
  of 
  th^ 
  Tezpur 
  

   district, 
  near 
  the 
  Bhoreli 
  river, 
  waterworn 
  pebbles 
  of 
  hard 
  rock 
  were 
  

   thrown 
  out 
  with 
  the 
  sand, 
  and 
  at 
  Haldibari, 
  in 
  Northern 
  Bengal, 
  

   lumps 
  of 
  "lava" 
  weighing 
  as 
  much 
  as 
  half 
  a 
  pound 
  were 
  thrown 
  out 
  

   with 
  the 
  sand. 
  On 
  examination 
  this 
  proved 
  to 
  be 
  what 
  is 
  known 
  

   in 
  India 
  as 
  jhama> 
  the 
  overburnt 
  bricks 
  from 
  the 
  lining 
  of 
  the 
  fire- 
  

   chambers 
  in 
  brick 
  clumps; 
  it 
  had 
  undergone 
  a 
  marked 
  decomposition 
  

   and 
  the 
  fragments 
  had 
  acquired 
  a 
  whitish 
  coating 
  ; 
  they 
  were 
  

   evidently 
  the 
  remains 
  of 
  an 
  old 
  brick 
  kiln, 
  which 
  had 
  long 
  been 
  buried 
  

   and 
  were 
  washed 
  up 
  with 
  the 
  sand 
  and 
  water 
  as 
  it 
  issued 
  from 
  the 
  

   ground. 
  

  

  In 
  the 
  inspection 
  notes 
  of 
  Lieutenant 
  Colonel 
  H. 
  St. 
  P. 
  Maxwell, 
  

   C.S.I., 
  Officiating 
  Commissioner 
  of 
  the 
  Assam 
  Valley 
  districts 
  1 
  , 
  two 
  

   instances 
  are 
  mentioned 
  which, 
  if 
  accepted 
  as 
  they 
  stand) 
  would 
  lead 
  

   to 
  a 
  very 
  exaggerated 
  idea 
  of 
  the 
  force 
  with 
  which 
  the 
  sand 
  and 
  water 
  

   issued, 
  and 
  for 
  that 
  reason 
  must 
  be 
  noticed 
  here. 
  The 
  first 
  of 
  these 
  

   is 
  at 
  Nowgong, 
  where 
  it 
  is 
  said 
  that 
  the 
  ejection 
  of 
  the 
  sand 
  had 
  

   such 
  force 
  that 
  covers 
  of 
  wells, 
  imbedded 
  in 
  mortar, 
  were 
  hurled 
  aside. 
  

   The 
  second 
  is 
  at 
  Goalpara, 
  where 
  it 
  is 
  said 
  that 
  a 
  well 
  was 
  altogether 
  

   filled 
  with 
  sand 
  and 
  a 
  portion 
  of 
  the 
  wooden 
  cover 
  was 
  hurled 
  30 
  

   feet 
  distant 
  where 
  it 
  lies 
  half 
  buried. 
  

  

  The 
  first 
  mentioned 
  instance 
  I 
  was 
  not 
  able 
  to 
  examine 
  person- 
  

   ally, 
  but 
  the 
  statement 
  that 
  the 
  force 
  of 
  the 
  issuing 
  sand 
  and 
  water 
  

   was 
  sufficient 
  to 
  detach 
  the 
  wooden 
  well 
  covers 
  may 
  be 
  accepted 
  

   as 
  correct 
  ; 
  the 
  other 
  statement, 
  regarding 
  the 
  well 
  at 
  Goalpara,
