  Lava 
  Flow 
  from 
  Maun 
  a 
  Loa, 
  1916. 
  273 
  

  

  1868 
  and 
  the 
  1887 
  flows. 
  At 
  about 
  seven 
  miles 
  (11*8 
  km.) 
  there 
  

   is 
  a 
  broad 
  rolling 
  paddock 
  with 
  sparse 
  koa. 
  Above 
  this 
  is 
  a 
  

   steeper 
  slope 
  of 
  koa 
  forest, 
  down 
  which 
  the 
  ancient 
  aa 
  flow, 
  Pele 
  

   o 
  Iki, 
  had 
  cut 
  a 
  swath. 
  Above 
  this 
  forest 
  is 
  an 
  extensive 
  bushy 
  

   upland 
  consisting 
  of 
  old 
  pahoehoe 
  and 
  aa 
  which 
  stretch 
  out 
  as 
  

   far 
  as 
  the 
  eye 
  can 
  reach 
  toward 
  distant 
  cones 
  and 
  on 
  the 
  west 
  to 
  

   the 
  rugged 
  ridges 
  of 
  the 
  1887 
  flow. 
  

  

  On 
  reaching 
  the 
  upper 
  edge 
  of 
  the 
  koa 
  slope, 
  it 
  was 
  found 
  that 
  

   the 
  fronts 
  of 
  the 
  new 
  flow 
  had 
  moved 
  down 
  more 
  than 
  a 
  mile

  (1*6 
  km.) 
  since 
  the 
  previous 
  morning 
  and 
  were 
  now 
  close 
  to 
  the 
  

   forest. 
  On 
  riding 
  up 
  the 
  west 
  side 
  of 
  the 
  flow, 
  which 
  was 
  in 
  

   process 
  of 
  overriding 
  Pele 
  o 
  Iki, 
  we 
  came 
  to 
  the 
  moving 
  lava 
  

   advancing 
  in 
  billows 
  and 
  cascades 
  of 
  red 
  hot 
  viscous 
  liquid 
  and 
  

   overflowing 
  the 
  already 
  cooled 
  aa 
  surface 
  of 
  the 
  previous 
  da} 
  T 
  . 
  

   The 
  moving 
  liquid 
  lay 
  in 
  streams 
  from 
  100 
  to 
  300 
  feet 
  (30 
  to 
  90 
  m.) 
  

   in 
  width 
  and 
  one 
  of 
  these 
  only 
  100 
  yards 
  (91 
  m.) 
  from 
  us 
  was 
  cours- 
  

   ing 
  down 
  the 
  main 
  lobe 
  of 
  the 
  previous 
  clay, 
  driving 
  in 
  front 
  of 
  

   it 
  a 
  fan-shaped 
  pool 
  of 
  dark 
  red 
  color 
  with 
  a 
  sugary 
  surface 
  which 
  

   advanced 
  at 
  the 
  rate 
  of 
  perhaps 
  a 
  half 
  a 
  mile 
  (800 
  m.) 
  per 
  hour. 
  

   The 
  cascades 
  above 
  carried 
  huge 
  rafts 
  and 
  bowlders 
  of 
  a 
  ten 
  to 
  

   thirty 
  feet 
  (3 
  to 
  10 
  m.) 
  in 
  diameter, 
  and 
  these 
  blocks 
  moved 
  along 
  

   majestically 
  in 
  a 
  procession, 
  about 
  as 
  fast 
  as 
  a 
  man 
  might 
  walk.
