  a 
  wide

  finally 
  a 
  slight 
  whitish 
  glare,

   ably 
  a 
  forest 
  blaze 
  at 
  the 
  extreme 
  east 
  limit 
  of 
  the 
  lava. 
  From 
  

   the 
  Volcano 
  Observatory 
  at 
  Kilauea 
  only 
  a 
  faint 
  radiance 
  was 
  

   seen. 
  

  

  At 
  8 
  a. 
  m. 
  May 
  28, 
  Vredenburg 
  was 
  at 
  the 
  vents 
  and 
  saw 
  slug- 
  

   gish 
  pahoehoe 
  emerging 
  from 
  the 
  Kahuku 
  vent, 
  and 
  occasional 
  

   spasmodic 
  spouting 
  from 
  the 
  northern 
  cone. 
  He 
  could 
  see 
  no 
  

   lava 
  flowing 
  towards 
  Kona. 
  No 
  movement 
  was 
  seen 
  in 
  the 
  

   Kahuku 
  flows.

  H.

  D. 
  Lycurgus

  the

   of 
  the 
  Kahuku 
  flows 
  on 
  the 
  south, 
  east 
  and 
  north. 
  The 
  fountain- 
  

   ing 
  at 
  the 
  sources 
  was 
  ceasing, 
  and 
  motion 
  in 
  the

   stopped."

  A. 
  Farrell 
  describes 
  a 
  visit 
  to 
  the 
  still 
  active 
  cones 
  from 
  the 
  

   Kona 
  side,* 
  May 
  27, 
  1916. 
  The 
  ascent 
  was 
  in 
  the 
  forenoon 
  

   from 
  Papa 
  to 
  the 
  7000-foot 
  (2300 
  m.) 
  level. 
  " 
  For 
  miles 
  before 
  

   we 
  reached 
  the 
  spatter-cone 
  we 
  heard 
  a 
  confused 
  but 
  contin- 
  

   uous 
  roar 
  directly 
  ahead 
  of 
  us. 
  . 
  . 
  . 
  We 
  saw 
  ahead 
  the 
  final 
  

   line 
  of 
  old 
  lava 
  ridges, 
  which 
  looked 
  down 
  on 
  the 
  fresh 
  black 
  

   flows. 
  From 
  behind 
  these 
  ridges 
  came 
  the 
  bombardment 
  of 
  

   the 
  fountains, 
  and 
  the 
  lire 
  of 
  mounting 
  jets 
  appeared 
  under 
  the 
  

   smoke 
  cloud 
  which 
  rose 
  over 
  our 
  heads." 
  

  

  On 
  reaching 
  the 
  last 
  ridge 
  glistening 
  black 
  pahoehoe 
  in 
  con- 
  

   fusion 
  was 
  seen, 
  glowing 
  with 
  red 
  lire 
  here 
  and 
  there 
  in 
  

   mounds, 
  overhung 
  on 
  the 
  south 
  by 
  a 
  curtain 
  of 
  heat 
  waves. 
  

   A 
  spatter-cone 
  was 
  belching 
  a 
  few 
  hundred 
  yards 
  away, 
  its 
  

   walls 
  split 
  by 
  a 
  great 
  rent 
  north 
  and 
  south. 
  Its 
  interior 
  glowed 
  

   and 
  two 
  jets 
  were 
  rising 
  from 
  it. 
  One 
  was 
  of 
  great 
  volume, 
  

   seemingly 
  four 
  or 
  live 
  times 
  the 
  size 
  of 
  an 
  average 
  Kilauea 
  

   fountain, 
  and 
  spurting 
  high 
  into 
  the 
  air 
  an 
  intensely 
  red 
  incan- 
  

   descent 
  fluid 
  as 
  a 
  single 
  jet. 
  The 
  jet 
  split 
  and 
  branched 
  into 
  

   filagree, 
  falling 
  as 
  black 
  rocks 
  " 
  in 
  sharp 
  outline 
  against 
  the 
  

   flaming 
  new-born 
  fluid." 
  Probably 
  the 
  cone 
  marked 
  " 
  7050 
  

   ft." 
  was 
  the 
  one 
  referred 
  to 
  (fig. 
  4). 
  

  

  There 
  was 
  no 
  roar 
  of 
  explosion 
  whatever, 
  only 
  the 
  clatter 
  of 
  

   falling 
  slag 
  striking 
  as 
  it 
  fell. 
  This 
  larger 
  jet 
  was 
  on 
  the 
  west 
  

   side 
  of 
  the 
  cone. 
  The 
  smaller 
  one 
  was 
  more 
  to 
  the 
  north, 
  

   throwing 
  small 
  bits 
  of 
  slag 
  twice 
  as 
  high 
  as 
  the 
  larger 
  foun- 
  

   tain, 
  which 
  as 
  they 
  descended 
  showed 
  the 
  effect 
  of 
  the 
  trade 
  

   wind, 
  for 
  all 
  that 
  fell 
  on 
  the 
  outside 
  steep 
  slopes 
  of 
  the 
  cone 
  

   fell 
  upon 
  the 
  leeward 
  side. 
  The 
  cone 
  was 
  slightly 
  higher 
  on 
  

   the 
  leeward 
  (west) 
  side. 
  (See 
  fig. 
  5. 
  The 
  heapings 
  on 
  the 
  left 
  

   are 
  the 
  leeward 
  accumulations. 
  The 
  cone 
  seen 
  by 
  Mr. 
  Farrell 
  

   was 
  probably 
  the 
  larger 
  smoking 
  peak 
  in 
  the 
  distance.)
