  free 
  from 
  such 
  except 
  in 
  places 
  where 
  ash. 
  has 
  rolled 
  down 
  from 
  above, 
  

   or 
  been 
  washed 
  on 
  to 
  it

  water.

  The 
  earliest 
  account 
  in 
  which 
  mention 
  

   is 
  made 
  of 
  the 
  lava 
  (rather 
  obscurely) 
  is 
  that 
  by 
  the 
  commander 
  of 
  a 
  

   ship 
  who 
  landed 
  in 
  March 
  1832.

  But, 
  judging 
  from 
  the 
  quantity 
  of 
  

   sand 
  that 
  has 
  been 
  washed 
  down 
  from 
  the 
  walls 
  of 
  the 
  ancient 
  crater 
  to 
  

   the 
  south, 
  and 
  covered 
  a 
  considerable 
  part 
  of 
  the 
  southern 
  lava 
  stream, 
  

   I 
  should 
  be 
  inclined 
  to 
  assign 
  the 
  greatest 
  possible 
  age 
  to 
  this 
  flow 
  at 
  least. 
  

   It 
  is 
  well 
  known 
  that 
  the 
  ejection 
  of 
  fragmentary 
  material 
  is 
  often 
  the 
  

   first 
  stage 
  of 
  an 
  eruption, 
  and 
  followed 
  by 
  the 
  emission 
  of 
  lava, 
  and 
  

   it 
  seems 
  very 
  probable 
  that 
  the 
  southern 
  stream 
  broke 
  out 
  immediately 
  

   after 
  the 
  eruption 
  witnessed 
  by 
  Blair. 
  Ihe 
  northern 
  stream 
  may 
  have 
  

   poured 
  forth 
  very 
  shortly 
  after, 
  but 
  there 
  is 
  no 
  positive 
  proof 
  of 
  its 
  exist- 
  

   ence 
  much 
  before 
  1858, 
  when 
  it 
  was 
  seen 
  by 
  Dr. 
  Liebig.

  State

  Column 
  of 
  smoke, 
  ascending 
  from 
  the 
  

   summit," 
  was 
  seen 
  from 
  a 
  distance 
  of 
  7 
  

   leagues. 
  No 
  nearer 
  approach 
  to 
  the 
  

   island 
  was 
  made. 
  

  

  The 
  volcano 
  was 
  in 
  a 
  violent 
  state 
  of 
  

   eruption, 
  bursting 
  out 
  immense 
  volumes 
  

   of 
  smoke, 
  and 
  frequently 
  showers 
  of 
  

   red-hot 
  stones. 
  Some 
  were 
  of 
  a 
  size 
  to 
  

   weigh 
  three 
  or 
  four 
  tons, 
  and 
  had 
  been 
  

   thrown 
  some 
  hundred 
  yards 
  past 
  the 
  

   foot 
  of 
  the 
  cone. 
  There 
  were 
  two 
  or 
  

   three 
  eruptions, 
  while 
  we 
  were 
  close 
  to 
  

   it; 
  several 
  of 
  the 
  red-hot 
  stones 
  rolled 
  

   down 
  the 
  sides 
  of 
  the 
  cone, 
  and 
  bounded 
  

   a 
  considerable 
  way 
  beyond 
  us.

  believe, 
  almost 
  entirely 
  due 
  to 
  the 
  breaking-up 
  of 
  the

   the
